PERFORMANCE

During the six month period ending June 30, 2007, the Batterymarch Growth and
Income Portfolio returned 8.04% versus 6.96% for the S&P 500(R) Index.

YOUR PORTFOLIO

For the period, the portfolio performance exceeded the S&P 500(R) Index
benchmark, benefiting from positive stock selection for the period, led by
selection in the transportation and financials--real estate sectors. Selection
in services & distribution was also strong. Stock selection in health care was
the greatest detractor. The impact of relative sector weightings was
essentially neutral.

Our stock selection model performed well for the period, with all of the
dimensions having positive top-to-bottom quintile spreads on an equal weighted
basis. The technical dimension led in the first quarter, while the earnings
growth and expectations dimensions led in the second quarter.

As of June 30, 2007, your Portfolio remained broadly diversified and
attractively valued compared with the benchmark, with a lower 12-month forward
price-to-earnings ratio and a strong two-year forward earnings growth rate.
Looking forward, your Portfolio is focused on stocks that rank attractively
relative to their peers across the dimensions of our stock selection model.

MARKET ENVIRONMENT

After a positive start to the year, markets globally suffered a correction
towards the end of February, sparked by a sharp one-day decline in local China
A shares. The downturn was exacerbated within the U.S. by sub-prime lending
concerns, with initial reaction centered on the stocks of mortgage lenders. The
second quarter began with benign economic data and strong corporate earnings
until news headlines, involving spikes in bond yields, hedge fund bailouts and
declining home sales, reawakened investors to economic risks. Still, consumer
spending remained stable, industrial growth continued and monetary policy
makers appeared satisfied with the current balance between currency stability
and economic growth. Merger and acquisition activity in the U.S. continued at a
high level, reflecting the global environment.

The leading sectors within the benchmark for the period were energy services,
materials and energy as oil process climbed. The only sectors posting negative
returns for the six-month period were financials--banks and financials--real
estate as sub-prime mortgage lending continued to worry investors.

OUTLOOK

Economic growth has moderated, and the Fed continues to monitor signs of
inflationary pressure. The consensus outlook for the U.S. economy therefore
remains mostly upbeat, having weathered much of the recent uncertainty. Our
portfolios are positioned for continued global growth that is not dependent on
the U.S. consumer as the primary source of demand.

INVESTMENT RESEARCH UPDATE

During the period, we completed research on ways to glean additional
information from corporate earnings announcements. As a result, we have
implemented a new Decayed 4-Day Relative Return factor within the expectations
dimension of our stock selection model. Decayed 4-Day Relative Return
encapsulates earnings information by calculating four-day relative returns
surrounding a company's earnings release. Share-price movement in the days
after an earnings announcement reflects not only earnings data, but also
insights about corporate guidance and future revenues.

We also completed research that furthers our ability to capture shifts in the
distribution of analyst opinions over time so that we can better understand and
exploit changes in market sentiment. As a result, we enhanced the Estimate
Diffusion Factor within our expectations dimension: we added a second
calculation for this factor that allows us to have a more complete picture of
the distribution of estimates and improves stock count, information ratio and
alpha spreads in peer groups where this factor is applied.

+The chart reflects the performance of Class A shares of the Portfolio. This is
currently the only active Class in the Portfolio.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-value weighted index (stock price times number of shares outstanding),
with each stock's weight in the Index proportionate to its market value. The
Index does not include fees or expenses and is not available for direct
investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gains distributions.

/3/Inception of Class A shares is 5/16/83. Index returns are based on an
inception date of 5/16/83. On May 1, 2006, the assets of The Travelers Growth
and Income Stock Account for Variable Annuities were transferred to the

Portfolio. The historical performance prior to this period is the performance
of the Portfolio's predecessor insurance company separate account managed by an
entity which became an affiliate of the Advisor in December 2005 using the same
investment objective and similar investment strategies as the Portfolio. The
separate account's performance reflects all expenses including Contract charges
since such charges were not separately stated from other account expenses.
Subsequent to May 1, 2006, the Portfolio's performance will not reflect
Contract charges. If Contract charges had been excluded from the performance
calculations, the performance numbers would have been higher. Prior to May 1,
2006, the Portfolio was not registered under the Investment Company Act of 1940
("1940 Act") and was not subject to certain investment limitations,
diversification requirements, and other restrictions imposed by the 1940 Act
and the Internal Revenue Code, which, if applicable, may have adversely
affected its performance.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Batterymarch Growth and Income Portfolio,
which is diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A Shares are offered
by the Portfolio. Class B and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Trust's Valuation
Committee. The Valuation Committee will regularly monitor and review the
services provided by the pricing service to the Portfolios and periodically
report to the Board on the pricing services' performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually

received or paid. Net unrealized foreign exchange gains and losses arise from
changes in the value of assets and liabilities other than investments in
securities at fiscal year end, from changes in the exchange rates of foreign
currency held, and from changes in the contract value of forward foreign
currency contracts.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary

affiliate of the Manager. MLIC receives no fees for its services to the Trust.
Prior to April 30, 2007, State Street Bank and Trust Company served as transfer
agent to the Trust.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement for the Portfolio is
permanent. Pursuant to that Expense Limitation Agreement, the Manager has
agreed to waive or limit its fees and to assume other expenses so that the
total annual operating expenses of the Portfolio other than interest, taxes,
brokerage commissions, other expenditures which are capitalized in accordance
with accounting principles generally accepted in the United States of America,
other extraordinary expenses not incurred in the ordinary course of the
Portfolio's business, but including amounts payable pursuant to a plan adopted

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. ACQUISITIONS

On May 1, 2006, Batterymarch Growth and Income Portfolio (the "Batterymarch
Portfolio") commenced operations after acquiring all of the net assets of The
Travelers Growth and Income Stock Account for Variable Annuities (the
"Travelers Account") pursuant to a plan of reorganization approved by the
Travelers Account unit holders on April 27, 2006. In a tax-free transaction,
the Travelers Account contributed net assets of $491,658,847, including
unrealized gains of $69,772,560, in exchange for 23,717,262 Class A shares of
the Batterymarch Portfolio.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MANAGED BY BATTERYMARCH FINANCIAL MANAGEMENT, INC.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


PERFORMANCE

During the six month period ending June 30, 2007, the Batterymarch Mid-Cap
Stock Portfolio returned 13.82% versus 11.98% for the S&P MidCap 400(R) Index.

YOUR PORTFOLIO

Your Portfolio outperformed the benchmark for the period, benefiting from
positive stock selection, led by energy, financials--real estate and
energy-services. Selection in the services & distribution sector was the
greatest detractor. The impact of sector allocation was essentially neutral.

Our stock selection model performed well for the period, with all of the
dimensions having positive top-to-bottom quintile spreads on an equal weighted
basis. The technical dimension led in the first quarter, while the earnings
growth and expectations dimensions led in the second quarter.

As of June 30, 2007, your Portfolio remained broadly diversified and
attractively valued compared with the benchmark, with a lower 12-month forward
price-to-earnings ratio and a strong two-year forward earnings growth rate.
Looking forward, your portfolio is focused on stocks that rank attractively
relative to their peers across the dimensions of our stock selection model.

MARKET ENVIRONMENT

After a positive start to the year, markets globally suffered a correction
towards the end of February, sparked by a sharp one-day decline in local China
A shares. The downturn was exacerbated within the U.S. by sub-prime lending
concerns, with initial reaction centered on the stocks of mortgage lenders.
Consumer spending remained stable, industrial growth continued and monetary
policy makers appeared satisfied with the current balance between currency
stability and economic growth. Merger and acquisition activity in the U.S.
continued at a high level, reflecting the global environment. Mid-cap stocks
outperformed large cap stocks for this period, with the S&P 400 at 5.8% vs the
S&P 500 at 0.6% in the second quarter. Large cap stocks benefited more from
this global exposure and outpaced mid-cap stocks in the second quarter while
still lagging year-to-date. For the first six months of the year, the S&P 400
returned 12.0% vs. the S&P 500 at 6.7%.

The leading sectors within the benchmark for the period were energy services,
industrials and materials. The only sectors posting negative returns for the
six-month period were financials--real estate as sub-prime mortgage lending
continued to worry investors, and consumer cyclicals.

OUTLOOK

Economic growth has moderated, and the Fed continues to monitor signs of
inflationary pressure. The consensus outlook for the U.S. economy therefore
remains mostly upbeat, having weathered much of the recent uncertainty. Our
portfolios are positioned for continued global growth that is not dependent on
the U.S. consumer as the primary source of demand.

INVESTMENT RESEARCH UPDATE

During the period, we completed research on ways to glean additional
information from corporate earnings announcements. As a result, we have
implemented a new Decayed 4-Day Relative Return factor within the expectations
dimension of our stock selection model. Decayed 4-Day Relative Return
encapsulates earnings information by calculating four-day relative returns
surrounding a company's earnings release. Share-price movement in the days
after an earnings announcement reflects not only earnings data, but also
insights about corporate guidance and future revenues.

We also completed research that furthers our ability to capture shifts in the
distribution of analyst opinions over time so that we can better understand and
exploit changes in market sentiment. As a result, we enhanced the Estimate
Diffusion Factor within our expectations dimension: we added a second
calculation for this factor that allows us to have a more complete picture of
the distribution of estimates and improves stock count, information ratio and
alpha spreads in peer groups where this factor is applied.

shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Batterymarch Mid-Cap Stock Portfolio,
which is diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A Shares are offered
by the Portfolio. Class B and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


FIXED INCOME MARKET

The Federal Reserve Board (Fed) continued to pause in its monetary tightening
campaign during the past six months, keeping the target federal funds rate at
5.25%. The Fed previously had raised the target rate in 17 increments of 25
basis points (0.25%) between June 2004 and June 2006. In the statement that
accompanied its news release following the May 28 meeting, the Federal Open
Market Committee (FOMC) again expressed its concern that "inflation will fail
to moderate as expected." The FOMC made clear that "future policy adjustments
will depend on the evolution of the outlook for both inflation and economic
growth, as implied by incoming information."

The U.S. Treasury yield curve began the six-month period slightly inverted
(i.e., short-term yields were higher than long-term rates). At December 31,
2006, the two-year U.S. Treasury note yielded 4.82% versus 4.71% for the
10-year note. However, the yield curve normalized during the period as the rise
in long-term yields considerably outpaced that in the shorter segment of the
curve. At the end of the period, the two- and 10-year Treasuries yielded 4.87%
and 5.03%, respectively.

The investment-grade sector of the fixed income market experienced some
volatility during the period amid an environment of generally rising interest
rates and weakness in the subprime mortgage market.

The below-investment-grade sector was one of the best-performing fixed income
areas during this period. As in other sectors, concerns over rising Treasury
yields, subprime mortgage market turmoil, and heavy leveraged buyout activity
led to periods of increased volatility. However, fundamentals remained strong
in the high yield market and spreads finished lower. Benign conditions such as
good liquidity, historically low default rates, and a favorable supply of new
issues helped to spur the sector and attract investors. For the six-month
period, the Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index
returned 2.96% versus the 0.98% return of the broad-market Lehman Brothers
Aggregate Bond Index/1/.

PORTFOLIO REVIEW

For the period, the Portfolio's relative performance continued to benefit from
its overweight exposure to lower-tier credits, particularly B-rated, CCC-rated
and C-rated issues, as these segments of the market posted the strongest
returns. Security selection in BB-rated issues was also a positive for the
Portfolio. The Portfolio's overweights in the media-non cable and wireless
sectors benefited performance for the period, while underweight exposures in
supermarkets and healthcare were detractors.
- --------
/1/ The Lehman Brothers Aggregate Bond Index represents securities that are
U.S. domestic, taxable, non-convertible and dollar denominated. The Index
covers the investment grade fixed rate bond market, with index components for
government and corporate securities, mortgage pass-through securities, and
asset-backed securities. The Index does not include fees or expenses and is not
available for direct investment.

At June 30, 2007, the Portfolio continued to hold an overweight in lower-rated
issues (B, CCC and C) as we expect that continued historically low default
rates and relatively strong fundamentals will help to support prices of the
underlying issues. The larger sector overweights in the Portfolio were in the
wireless, media-non cable, retail and chemicals sectors, and the larger sector
underweights were in automotive, food and supermarkets.

+The chart reflects the performance of Class A shares of the Portfolio. This is
currently the only active Class in the Portfolio.

/1/The Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index is
composed of fixed rate non-investment grade debt with at least one year
remaining to maturity that are dollar-denominated, nonconvertible and have an
outstanding par value of at least $100 million. The Index does not include fees
or expenses and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gains distributions.

/3/Inception of Class A shares is 08/30/1996. Index returns are based on an
inception date of 8/31/1996.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is BlackRock High Yield Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A Shares are offered
by the Portfolio. Class B and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                            Expiring   Expiring   Expiring   Expiring

- ---------                      ----------- ---------- ---------- ---------- ----------
                                                             

BlackRock High Yield Portfolio $13,235,077 $4,592,238 $6,217,956 $1,599,086  $825,797


On May 1, 2006, the Federated High Yield Portfolio, a series of The Travelers
Series Trust, was reorganized into the Federated High Yield Portfolio, a series
of Met Investors Series Trust. The Portfolio acquired capital losses of
$13,291,427. The losses incurred by the Portfolio are subject to an annual
limitation of $3,740,137.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

G. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

unrealized foreign exchange gains and losses arise from changes in the value of
assets and liabilities other than investments in securities at fiscal year end,
from changes in the exchange rates of foreign currency held, and from changes
in the contract value of forward foreign currency contracts.

H. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

I. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of collateral decreases below the value of the securities loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

9. ACQUISITION

On April 30, 2007, BlackRock High Yield Portfolio ("BlackRock"), a series of
Met Investors Series Trust, acquired all the net assets of Western Asset
Management High Yield Bond Portfolio ("Western"), a series of Metropolitan
Series Fund, Inc., pursuant to a plan of reorganization approved by Western
shareholders on April 24, 2007. The acquisition was accomplished by a tax-free
exchange of 10,512,242 Class A shares of Western (valued at $100.8 Million) in
exchange for the 12,027,317 Class A shares of BlackRock outstanding on
April 27, 2007. Western Class A net assets at that date ($100.8 Million),
including $3,537,529 of unrealized appreciation and approximately $1,258,595 of
accumulated net realized gains, were combined with those of BlackRock Class A.
The aggregate Class A net assets of BlackRock and Western immediately before
the acquisition were $78,433,253 and $100,788,917, respectively. The aggregate
Class A net assets of BlackRock immediately after the acquisition were
$179,222,170.

10. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

11. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

ECONOMIC OVERVIEW & OUTLOOK

U.S. equity markets generally gained ground in the first six months of 2007.
The broad-market S&P 500(R) Index/1/ rose 6.28%. Shares of large-cap growth
stocks outperformed large-cap value stocks, with the Russell 1000(R) Growth
Index/2/ gaining 8.13% versus the 6.23% return of the Russell 1000(R) Value
Index/3/ for the period.

Slow economic growth and credit-related problems such as the ongoing subprime
lending issue and some high-profile losses in the hedge fund industry do have
the potential to increase financial stresses in the months ahead. While such
strains would unsettle the equity and corporate bond markets, we do not believe
they will mark the end of the liquidity-driven bull market in "riskier" assets.
The financial environment has become more turbulent, but not to the point that
it poses a major challenge to economic stability or to the ongoing bull market
in stocks. Our overarching equity-related comment from the beginning of the
year was that stock markets would experience a "reasonably constructive" year,
and this view has not changed. In our interpretation, "constructive" means an
up year and "reasonably" means less so than last year and with more volatility
along the way. Year-to-date, returns for equities have been quite good, but
have come with some disruptive bumps along the way. Looking ahead, we believe
stock prices to finish the year higher than where they were at quarter-end, but
the overall pace of gains is likely to be slower in the second half of the year.

From a big picture perspective, the economic and financial environment remains
in remarkably good shape, given the various events of recent years. For
example, the global economy is enjoying its

strongest run of growth in three decades, yet inflation is low; the equity bull
market is in its fifth year, yet valuations are reasonable in most regions; the
U.S. housing bubble has burst, yet there has been little impact on employment
and consumer spending. The favorable environment owes a lot to the bullish
effects of globalization, technological innovations and market reforms.
Importantly, these are long-term structural, and not cyclical, developments.
The equity market may struggle in the near term if credit market turmoil
worsens, but we do not believe that a bear market is in the cards.

PORTFOLIO OVERVIEW

During the period, BlackRock Large-Cap Portfolio a series of the Metropolitan
Series Fund, Inc. was merged into the BlackRock Large-Cap Core Portfolio of the
Met Investors Series Trust.

For the six-month period ended June 30, 2007, the Class A shares of the
BlackRock Large-Cap Core Portfolio returned 5.97%, compared to its benchmark,
the Russell 1000(R) Index/4/, which returned 7.18%.

The Portfolio held overweight positions relative to the benchmark in
information technology, consumer discretionary, energy, healthcare and, to a
lesser degree, materials. There were underweights in the financials, utilities,
telecommunication services, consumer staples and industrials sectors.

The Portfolio's performance in comparison to that of the benchmark was hindered
by stock selection and an overweight position in the consumer discretionary
sector; stock selection in information technology, industrials and consumer
staples; underweight positions in telecommunication services, utilities and
industrials; and overweights in healthcare and industrials. Portfolio
performance benefited, however, from stock selection and an overweight position
in the energy sector; stock selection and an underweight in financials; and
stock selection in healthcare and materials.

The investment objective of the BlackRock Large-Cap Core Portfolio is to seek
long-term growth of capital through investments primarily in a diversified
portfolio of equity securities of large-cap companies located in the United
States. The Portfolio uses an investment approach that blends growth and value.

+The chart reflects the performance of Class A shares of the Portfolio.

/1/The Russell 1000(R) Index is an unmanaged index which measures the
performance of the 1,000 largest companies in the Russell 3000 Index, which
represents approximately 92% of the total market capitalization of the Russell
3000 Index. As of latest reconstitution, the average market capitalization was
approximately $16.3 billion; the median market capitalization was approximately
$6.1 billion. The smallest company in the index had an approximate market
capitalization of $2.5 billion. The Index does not include fees and expenses
and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gains distributions.

/3/Inception of Class A shares is 3/23/1998. Inception of Class B and Class E
shares is 4/30/2007. Index returns are based on an inception date of 3/31/1998.

/4/"Cumulative Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is BlackRock Large-Cap Core Portfolio, which
is diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B, and E Shares
are offered by the Portfolio. Shares of each Class of the Portfolio represent
an equal pro rata interest in the Portfolio and generally give the shareholder
the same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                                      13



                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                     Expiring    Expiring
     Portfolio                             Total    12/31/2009  12/31/2010
     ---------                          ----------- ----------- -----------
                                                       

     BlackRock Large-Cap Core Portfolio $61,967,454 $23,132,070 $38,835,384


On May 1, 2006, the BlackRock Large-Cap Core Portfolio, a series of The
Travelers Series Trust, was reorganized into the BlackRock Large-Cap Core
Portfolio, a series of Met Investors Series Trust. The Portfolio acquired
capital losses of $67,463,346. The losses incurred by the Portfolio are subject
to an annual limitation of $5,495,892.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MARKET OVERVIEW

Continuing the general trend of the past four years, financial markets
progressed markedly during the first half of 2007. Volatility returned to the
markets with episodic appearances over the past six months. Global markets
dropped sharply in February on fears of a slowdown in U.S. economic growth from
a subprime lending meltdown. Despite significant declines, markets recovered
sharply and ended the first quarter on a positive note. The advancement
continued during the second quarter as markets remained resilient and the Dow
and S&P 500(R) Index reached all-time highs. Year-to-date through June 30, the
S&P 500(R) Index returned 6.96%, the S&P MidCap 400(R) Index returned 11.9%,
and the S&P SmallCap 600(R) Index returned 8.6%. Energy was the best performing
sector across large-cap and mid-cap stocks, while materials dominated in
small-caps. Financials were the biggest laggard across all market
capitalizations. Foreign stocks, as measured by the MSCI EAFE(R) Index,
returned 10.7% in light of continued strong economic growth abroad. Bonds
underperformed equities with the Lehman Brothers Aggregate Bond Index/1/
returning 0.98%.

PORTFOLIO STRATEGIES

For the six-month period ended June 30, 2007, the Portfolio (Class B) returned
6.30%, outperforming both the S&P 500 and its blended benchmark which returned
6.96% and 5.70% respectively. From an asset class perspective, the Portfolio's
significant overweight to equities versus bonds relative to the blended
benchmark aided returns. The Portfolio maintained a weighting of close to 15%
in fixed-income exchange traded funds during the period, which was
substantially less than the 38% allocation to bonds in the blended benchmark.
This positioning greatly aided relative performance as equity markets posted
strong gains.

With regard to equity positioning, underweighting small-caps detracted from
performance as smaller capitalization stocks outperformed large-caps. The
Portfolio was void of small-cap exposure despite small-cap stocks representing
10% of the blended benchmark. We continue to find large-cap stocks attractive
and maintain a substantial overweight to this asset class relative to the
blended benchmark. Large-cap stocks have generated strong absolute returns
through the first half of 2007, aiding Portfolio returns, but have lagged mid-
and small-caps. The Portfolio maintained a benchmark weight of 5% to foreign
equities which aided absolute returns.

Within the large-cap portion of the Portfolio, sector allocation aided relative
performance. An underweight position in consumer discretionary accounted for
most of the relative outperformance as the sector lagged the S&P 500(R) Index
through the first half of the year. The Portfolio's overweight to health care
also aided relative performance. On the negative side, an underweight of
materials and overweight of consumer staples detracted from relative
performance.

/1/ The Lehman Brothers Aggregate Bond Index represents securities that are
U.S. domestic, taxable, non-convertible and dollar denominated. The Index
covers the investment grade fixed rate bond market, with index components for
government and corporate securities, mortgage pass-through securities, and
asset-backed securities. The Index does not include fees or expenses and is not
available for direct investment.

OUTLOOK

The rate of economic growth in the U.S. has slowed in recent quarters. We
believe we are moving through the low point of the cycle and expect growth to
gradually improve in coming quarters. From a cyclical viewpoint, we believe
this growth will be sufficient to support corporate profits and economic
expansion. Along with the outlook for corporate profits, we prefer large-cap
stocks based on their attractive valuation relative to smaller capitalization
stocks. With regard to sector allocation, we maintain an overweight to consumer
staples and healthcare as these non-cyclical sectors tend to perform well at
this point in the cycle. Continued exposure to domestic mid-cap and foreign
developed country stocks provides additional growth opportunities and portfolio
diversification. Our fixed-income focus is on high-quality, short- to
intermediate-maturity bonds. We see relatively attractive yields in these areas
of the fixed-income market.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-value weighted index (stock price times number of shares outstanding),
with each stock's weight in the Index proportionate to its market value. The
Index does not include fees or expenses and is not available for direct
investment.

/2/The blended benchmark is comprised of 2% Merrill Lynch U.S. 3-Month Treasury
Bill Index, 10% Merrill Lynch Corporate/Government Master Index, 48% S&P 500(R)
Index, 15% S&P MidCap 400(R) Index, 15% S&P SmallCap 600(R) Index and 10%
Morgan Stanley Capital International Europe, Australia and Far East Index
("MSCI EAFE(R) Index").

The Merrill Lynch U.S. 3-Month Treasury Bill Index is composed of a single
90-Day Treasury bill issue, or potentially a seasoned 6-month or 1-year
Treasury bill issue, that is replaced on a monthly basis. The Index does not
include fees or expenses and is not available for direct investment.

The Merrill Lynch Corporate/Government Master Index is an indicator of the
performance of investment-grade domestic bonds, capturing close to $5 trillion
of outstanding debt. The Index does not include fees or expenses and is not
available for direct investment.

The S&P MidCap 400(R) Index is a capitalization-weighted index which measures
the performance of the mid-range sector of the U.S. stock market. The Index
does not include fees or expenses and is not available for direct investment.

The S&P SmallCap 600(R) Index is a capitalization-weighted index which measures
the performance of the small-cap range of the U.S. stock market. The Index does
not include fees or expenses and is not available for direct investment.

The MSCI EAFE(R) Index is a widely recognized unmanaged index which is an
aggregate of 15 individual country indices that collectively represent many of
the major markets of the world. An index does not include transaction costs
associated with buying and selling securities or any mutual fund expenses. The
Index does not include fees or expenses and is not available for direct
investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of Class B shares is 10/3/05. Inception of Class A and Class E
shares is 5/1/06. Index returns are based on an inception date of 9/30/05.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)


1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Cyclical Growth and Income ETF Portfolio,
which is diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. REPURCHASE AGREEMENT - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

G. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with Gallatin Asset Management, Inc., (the "Adviser") for investment advisory
services in connection with the investment management of the Portfolio.

Subject to the supervision and direction of the Board, the Manager supervises
the Adviser and has full discretion with respect to the retention or renewal of
the advisory agreement. The Manager pays the Adviser a fee based on the
Portfolio's average daily net assets.

the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

10. OTHER MATTERS

The Portfolio does not invest in the Underlying Portfolios for the purpose of
exercising management or control; however, investments by the Portfolio within
its principal investment strategies may represent a significant portion of an
Underlying Portfolio's net assets. At the end of the period, the Portfolio was
not the owner of record of 5% or more of the total outstanding shares of any
Underlying Portfolios.

MARKET OVERVIEW

Continuing the general trend of the past four years, financial markets
progressed markedly during the first half of 2007. Volatility returned to the
markets with episodic appearances over the past six months. Global markets
dropped sharply in February on fears of a slowdown in U.S. economic growth from
a subprime lending meltdown. Despite significant declines, markets recovered
sharply and ended the first quarter on a positive note. The advancement
continued during the second quarter as markets remained resilient and the Dow
and S&P 500(R) Index reached all-time highs. Year-to-date through June 30, the
S&P 500(R) Index returned 6.96%, the S&P MidCap 400(R) Index returned 11.9%,
and the S&P SmallCap 600(R) Index returned 8.6%. Energy was the best performing
sector across large-cap and mid-cap stocks, while materials dominated in
small-caps. Financials were the biggest laggard across all market
capitalizations. Foreign stocks, as measured by the MSCI EAFE(R) Index,
returned 10.7% in light of continued strong economic growth abroad. Bonds
underperformed equities with the Lehman Brothers Aggregate Bond Index/1/
returning 0.98%.

PORTFOLIO STRATEGIES

For the six-month period ended June 30, 2007, the Portfolio (Class B) returned
7.73%, outperforming both the S&P 500 and its blended benchmark which returned
6.96% and 7.66% respectively. From an asset class perspective, overweighting
equities versus bonds relative to the blended benchmark aided Portfolio
returns. With regard to equity positioning, underweighting small-caps detracted
from performance as smaller capitalization stocks outperformed large-caps. The
Portfolio was void of small-cap exposure despite small-cap stocks representing
15% of the blended benchmark. We continue to find large-cap stocks attractive
and maintain a substantial overweight to this asset class relative to the
blended benchmark. Large-cap stocks have generated strong absolute returns
through the first half of 2007, aiding Portfolio returns, but have lagged mid-
and small-caps. The Portfolio maintained a benchmark weight of 10% to foreign
equities which aided absolute returns.

Within the large-cap portion of the Portfolio, sector allocation aided relative
performance. An underweight position in consumer discretionary accounted for
most of the relative outperformance as the sector lagged the S&P 500(R) Index
through the first half of the year. The Portfolio's overweight to health care
also aided relative performance. On the negative side, an underweight of
materials and overweight of consumer staples detracted from relative
performance.

OUTLOOK

The rate of economic growth in the U.S. has slowed in recent quarters. We
believe we are moving through the low point of the cycle and expect growth to
gradually improve in coming quarters. From a cyclical
- --------
/1/ The Lehman Brothers Aggregate Bond Index represents securities that are
U.S. domestic, taxable, non-convertible and dollar denominated. The Index
covers the investment grade fixed rate bond market, with index components for
government and corporate securities, mortgage pass-through securities and
asset-backed securities. The Index does not include fees or expenses and is not
available for direct investment. viewpoint, we believe this growth will be
sufficient to support corporate profits and economic expansion. Along with the
outlook for corporate profits, we prefer large-cap stocks based on their
attractive valuation relative to smaller capitalization stocks. With regard to
sector allocation, we maintain an overweight to consumer staples and healthcare
as these non-cyclical sectors tend to perform well at this point in the cycle.
Continued exposure to domestic mid-cap and foreign developed country stocks
provides additional growth opportunities and portfolio diversification.

+The chart reflects the performance of Class B shares of the Portfolio. The
Performance of Class B shares will differ from that of the other classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-value weighted index (stock price times number of shares outstanding),
with each stock's weight in the Index proportionate to its market value. The
Index does not include fees or expenses and is not available for direct
investment.

/2/The blended benchmark is comprised of 2% Merrill Lynch U.S. 3-Month Treasury
Bill Index, 10% Merrill Lynch Corporate/Government Master Index, 48% S&P 500(R)
Index, 15% S&P MidCap 400(R) Index, 15% S&P SmallCap 600(R) Index and 10%
Morgan Stanley Capital International Europe, Australia and Far East Index
("MSCI EAFE(R) Index").

The Merrill Lynch U.S. 3-Month Treasury Bill Index is composed of a single
90-Day Treasury bill issue, or potentially a seasoned 6-month or 1-year
Treasury bill issue, that is replaced on a monthly basis. The Index does not
include fees or expenses and is not available for direct investment.

The Merrill Lynch Corporate/Government Master Index is an indicator of the
performance of investment-grade domestic bonds, capturing close to $5 trillion
of outstanding debt. The Index does not include fees or expenses and is not
available for direct investment.

The S&P MidCap 400(R) Index is a capitalization-weighted index which measures
the performance of the mid-range sector of the U.S. stock market. The Index
does not include fees or expenses and is not available for direct investment.

The S&P SmallCap 600(R) Index is a capitalization-weighted index which measures
the performance of the small-cap range of the U.S. stock market. The Index does
not include fees or expenses and is not available for direct investment.

The MSCI EAFE(R) Index is a widely recognized unmanaged index which is an
aggregate of 15 individual country indices that collectively represent many of
the major markets of the world. An index does not include transaction costs
associated with buying and selling securities or any mutual fund expenses. The
Index does not include fees or expenses and is not available for direct
investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of Class B shares is 10/3/05. Inception of Class A and Class E
shares is 5/1/06. Index returns are based on an inception date of 9/30/05.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)


1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Cyclical Growth ETF Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

G. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

10. OTHER MATTERS

The Portfolio does not invest in the Underlying Portfolios for the purpose of
exercising management or control; however, investments by the Portfolio within
its principal investment strategies may represent a significant portion of an

Underlying Portfolios.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


DREMAN SMALL-CAP VALUE PORTFOLIO

Except for a period of weakness in late February and early March, equity
markets were quite strong during the first six months of 2007. By the end of
May, most indices were at or near their all-time highs; markets were volatile
with no pronounced trend in June. The Russell 3000(R) Index/1/, which is
generally regarded as a good indicator of the broad stock market, returned
7.11% for the six-month period. The Small Cap Russell 2000(R) Index/2/ returned
6.45%. Within all capitalization categories, using the Russell growth and value
indices for measurement, growth stocks performed better than value stocks.

During the six month period ending June 30, 2007, the Portfolio returned 8.52%;
while the benchmark (the Russell 2000 Value Index/3/) returned 3.80%,
outperforming the Index by 497 basis points.

An important factor in the fund's strong performance was not owning some of the
worst performing issues in the financials sector, particularly mortgage
companies and real estate investment trusts. An underweight position in banks
was also positive. Holdings in the information technology sector contributed to
performance, particularly communications equipment manufacturers CommScope,
Inc. and Anixter International Inc. As in past periods, energy holdings
contributed to performance, especially Atwood Oceanics, Inc., Superior Energy
Services, Inc., Uranium Resources PLC, and OMI Corp., a marine shipper or
petroleum products that agreed to be acquired.

The major detractor from performance was not having a significant position in
the materials sector, which performed very well. At this late stage of an
economic expansion, we have difficulty finding good values among these highly
cyclical stocks. However, a position in Uranium Resources Plc, a uranium
exploration and development company focused in southern Tanzania, contributed
to performance.

Messrs. David N. Dreman, E. Clifton Hoover Jr., and Mark Roach have served as
the day-to-day portfolio managers of the portion of the Portfolio's assets
allocated to Dreman. Mr. Dreman has been part of the management team since the
Portfolio's inception in 2005.
Mr. Dreman is the founder, Chairman and Chief Investment Officer of Dreman
Value Management, LLC. Mr. Hoover has been a Managing Director of Large and
Small Cap products, and the co-Chief Investment Officer of Dreman Value
Management since December 2006.
Mr. Roach joined DVM in November 2006 as a Managing Director and Portfolio
Manager of Small and Mid Cap products.

The views expressed above are those of the investment subadvisory firm and are
subject to change based on market and other conditions, and no forecast can be
guaranteed. Information about the Portfolio's holdings, asset allocation,
industry allocation or country diversification is historical and is not an
indication of future portfolio composition which will vary.

+The chart reflects the performance of Class A shares of the Portfolio. This is
currently the only active Class in the Portfolio.

/1/The Russell 2000(R) Value Index is an unmanaged index which measures the
performance of those Russell 2000 companies with lower price-to-book ratios and
lower forecasted growth values. The Index does not include fees or expenses and
is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividend and capital gains distributions.

/3/Inception of Class A shares is 05/02/2005. Index returns are based on an
inception date of 4/30/2005.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)


1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Dreman Small-Cap Value Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A Shares are offered
by the Portfolio. Class B and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

G. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

H. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


PERFORMANCE REVIEW

For the six month period ended June 30, 2007, the Goldman Sachs Mid-Cap Value
Portfolio Class A shares returned 9.84% versus 8.69% for its benchmark, the
Russell Midcap(R) Value Index./1/

MARKET REVIEW

The U.S. equity markets hit new highs during the reporting period. While the
equity markets finished the first half of the year in positive territory,
concerns related to subprime loans undercut investor optimism as markets closed
the quarter on a cautious note. Consistent with recent trends, leveraged buyout
and merger and acquisition (M&A) activity remained high as corporate and
private buyers sought attractive assets. On the economic front, the Federal
Reserve Board kept short-term interest rates steady while bond yields spiked
above 5% in June.

PORTFOLIO POSITIONING

During the six-month reporting period, the Goldman Sachs Mid-Cap Value
Portfolio generated positive returns and outperformed the returns of the
Russell Midcap(R) Value Index. The Portfolio's stocks in the energy and
healthcare sectors led performers while its holdings in the technology and
financials sectors detracted from results.

In the first six months of the year, a mix of successful stock picking and
favorable acquisition activity drove the Portfolio's relative gains. Several of
the Portfolio's Energy positions, such as EOG Resources, Inc. (1.4% of the
Portfolio) and Range Resources Corp. (3.1%), rebounded from last year's
weakness to lead performance year-to-date. We continue to favor Energy
companies with a mix of low cost structures, positive reserve trends and
disciplined management teams. The Portfolio also benefited from M&A activity as
MedImmune (0.0%) was acquired by AstraZeneca at a sizable premium. MedImmune
had long served as an example of what we considered a mis-priced company
despite its robust pipeline of products. We subsequently sold our stake after
the shares rose sharply on the news. Other holdings in the Portfolio that
contributed to positive returns included Supervalu, Inc. (2.0%) and PPL Corp.
(2.3%).

Several investments offset gains in the portfolio for the six-month reporting
period. In technology, shares of Seagate Technology (1.1%) declined as the
company faced aggressive competition and pricing pressures. While we managed to
avoid many of the sharp losses in the homebuilders sector, Lennar Corp. (0.6%)
was still hit by housing concerns. We think this turnaround story is still
attractive over the long term, but reduced the position to reflect near term
uncertainty. Elsewhere, KeyCorp (1.9%) and Webster Financial Corp.

/1/ The Russell Midcap(R) Value Index is an unmanaged index of common stock
prices that measures the performance of those Russell Midcap companies with
lower price-to-book ratios and lower forecasted growth values. The S&P 500(R)
Index is the Standard & Poor's 500 Composite Index of 500 stocks, an unmanaged
index of common stock prices. The Index figures do not reflect any deduction
for fees, expenses or taxes. It is not possible to invest directly in an
unmanaged index.
(1.2%) both experienced weakness as both companies lowered their near term
outlooks. We continue to view both stocks as attractive opportunities.

OUTLOOK

Many of our Portfolio's best performing stocks in 2007 have been companies
engaged in efforts to rationalize their cost structures, divest non-strategic
assets and generally improve returns on capital. As we move into the second
half, we will continue to seek similar opportunities as these programs of
internal change can show positive results in an uncertain market environment.
We believe the market will continue to see a healthy flow of private equity
investment into mid-cap companies, particularly those with the cash flow
characteristics we tend to favor.

TEAM MANAGED

The Portfolio is managed by a team headed by Eileen Rominger, Managing Director
and Chief Investment Officer--Value. Ms. Rominger joined Goldman Sachs in 1999.
From 1981-1999, Ms. Rominger worked at Oppenheimer Capital, most recently as a
senior portfolio manager.

The Portfolio invests primarily in mid-capitalization U.S. equity investments
and is subject to market risk so that the value of the securities in which it
invests may go up or down in response to the prospects of individual companies,
particular industry sectors and/or general economic conditions. The securities
of mid-capitalization companies involve greater risks than those associated
with larger, more established companies and may be subject to more abrupt or
erratic price movements.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B shares
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The Russell Midcap(R) Value Index is an unmanaged index of common stock
prices which measures the performance of those Russell Midcap companies with
lower price-to-book ratios and lower forecasted growth values. The stocks are
also members of the Russell 1000 Value(R) Index. The Index does not include
fees or expenses and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A and Class B shares is 5/1/04. Index returns are
based on an inception date of 4/30/04.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)


1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Goldman Sachs Mid-Cap Value Portfolio,
which is diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                           JUNE 30, 2007 (UNAUDITED)


2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with Goldman Sachs Asset Management, L.P., (the "Adviser") for investment
advisory services in connection with the investment management of the Portfolio.

Subject to the supervision and direction of the Board, the Manager supervises
the Adviser and has full discretion with respect to the retention or renewal of
the advisory agreement. The Manager pays the Adviser a fee based on the
Portfolio's average daily net assets.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing
distribution and shareholder servicing with respect to the Class B and Class E
Shares for such entities' fees or expenses incurred or paid in that regard.

Goldman Sachs Mid-Cap Value Portfolio  $13,979,514   $34,448,881  $56,214,981         $--         $104,643,376


The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

QUARTERLY PORTFOLIO SCHEDULE

MARKET & ECONOMIC REVIEW:

CHINA, UNSAFE AT ANY SPEED?

We receive many questions as to why we remain uninvested in China, the world's
fastest growing major economy. Recall, we are long-term value investors,
seeking to invest in companies that are not only high quality but also sell at
low prices. Today the stocks of Chinese companies represent neither: they are
richly priced and low quality. Most major Chinese companies are still state
controlled, which means that politics will most certainly enter corporate
decision making. The state is directly involved in critical banking matters,
ranging from capital allocation to pricing to investment criteria, all of which
could lead to less than optimal results for foreign investors. Although the
lack of environmental regulations in China has helped it become a low cost
country for producing goods and has attracted manufacturers from all over the
world, its air, water, and soil have rapidly deteriorated. Additionally,
aggressive "entrepreneurs" have called into question the safety and quality of
much of what has been produced. Recently, pet food, toys, tooth paste, cough
syrup, and ATVs have been made either toxic by the addition of cheap materials
or unsafe by poor design. We believe that China will have to deal with these
issues, which will eventually affect the cost of production and possibly make
it a less competitive place to invest and produce. In our view the current pace
of environmental decay, if maintained, would be catastrophic not only for China
but also for the globe. It is true that there will be growth in China for as
far as the eye can see: strong growth in fixed capital, economic
liberalization, and some positive microeconomic fundamentals will lead to
productivity enhancement. However, this does not mean it is safe to invest in
Chinese stocks at today's prices, and we will continue to avoid these stocks
because of their inflated valuations, corporate governance issues and political
risk.

PERFORMANCE AT-A-GLANCE

At this time, we are quite enthused with the make-up of the portfolio, and we
believe it will continue to outperform in the long-term. We feel that risk is
being mispriced in global equity markets and that the undervalued and high
quality companies in our portfolios will eventually deliver strong performance.
Today's "dogs"--those stocks that have been a drag on portfolio return--often
turn into tomorrow's stars. We are quite confident that those securities that
have dampened performance will not only recover but will lead to solid absolute
and relative performance. For the six-months ending June 30, 2007 the MSCI
EAFE(R) Index returned 9.48% and the Portfolio slightly under-performed the
Index for the same period.

PORTFOLIO PERFORMANCE REVIEW:

For the six months ended June 30/th/ 2007 the largest contributors to the
Portfolio's performance were DAIMLERCHRYLSER, NIKKO CORDIAL CORP., BRITISH SKY
BROADCASTING ("BSKYB") and CADBURY SCHWEPPES.

DAIMLER, the top performer for the period returned 53%. Most of the stock
price's increase resulted from the announcement of the sale of 80% of the
Chrysler division to Cerberus. While Daimler AG will maintain 20% ownership in
Chrysler Holding LLC, it will be divested of the pension and health care
obligations.

NIKKO CORDIAL is a Japanese investment firm and the country's third largest
brokerage firm. We invested in Nikko towards the end of 2006 after the share
price had been hit exceptionally hard due to a relatively small accounting
scandal that raised the possibility of the stock being de-listed from the Tokyo
exchange. We believed that Nikko offered significantly higher return potential
because, in addition to the company's exceptionally strong franchise, the
Japanese investment sector presented huge growth opportunities. This
opportunity is the result of recent Japanese regulations that allow investors
to move savings from deposits that earned less than 1% to products and funds
offered by Nikko that could offer significantly higher returns. Additionally,
because those who were involved in the accounting scandal were fired, we
estimated that it was improbable that the stock would be de-listed. Our
hypotheses were mostly correct about the strength of Nikko's business and the
Japanese exchange's action, and we correctly assumed that Citigroup, who owned
approximately 5% of Nikko and runs a joint venture with them, would be
interested in bidding for the company. As a result, Nikko's share price
increased almost 25% in the first quarter. We did not, however, anticipate that
Nikko's management would seem more interested in pleasing Citigroup than in
serving the other 95% of its shareholders. Sadly, once Citigroup expressed
interest in buying the company, Nikko's management seemed to actively
discourage other interested parties. We have trimmed our position as a result
of the share price's massive appreciation, but our preference at this time
would be to remain Nikko shareholders given the unsatisfactory price that
Citigroup is offering.

BSKYB, the United Kingdom's number one pay-television operator, returned 27% in
the period. In addition to continued strong results in its pay-television
business, BskyB has made excellent progress in attracting both new and existing
customers to its recently launched broadband and telephony service.

Rounding out the top four was CADBURY SCHWEPPES, a UK-based confectionary and
beverage company. Most of the 26% increase in price followed the mid-March
announcement that a leading hedge fund had taken interest in 3% of issued share
capital, which generated market speculation that the company was a takeover
target. Bowing to pressure led by the new hedge fund activist, Cadbury
announced the spin-off of its North American beverage unit, the maker of
Dr. Pepper and 7 Up.

On the negative side, shares of Japanese security ROHM CO. lagged during the
period mostly due to an industry-wide weakness for semiconductor-related stocks.

OUTLOOK:

The strong global equity market of 2006 continued into the first six weeks of
2007. However, global markets began an abrupt sell-off in late February,
triggered by a 9% decline in the Chinese market. Despite all of the panicky
headlines, we view this as normal equity market behavior and continue to focus
on finding value--searching for high quality businesses that sell at attractive
prices. Market sell-offs actually help our quest because they provide us with
more investment opportunities. Keep in mind that we strongly believe that the
way to achieve investment success over time is to stay focused on the long

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The Morgan Stanley Capital International Europe, Australasia and Far East
Index ("MSCI EAFE(R) Index") is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance, excluding the U.S. & Canada. The Index does not include fees or
expenses and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A shares is 1/2/02. Inception of the Class B shares
is 10/9/01. Inception of the Class E shares is 4/01/02. Index returns are based
on an inception date of 10/9/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)


1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Harris Oakmark International Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                        Expiring   Expiring

    ---------                              ----------- ---------- ----------
                                                         

    Harris Oakmark International Portfolio $12,186,002 $4,729,888 $7,456,114


Harris Oakmark International Portfolio acquired losses of $17,613,489 in the
merger with TST-Mondrian International Stock Portfolio on May 1, 2006 which are
subject to an annual limitation of $8,141,230.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

G. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


H. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

I. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

J. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

9. ACQUISITIONS

On May 1, 2006, Harris Oakmark International Portfolio ("Harris Oakmark")
acquired all of the net assets of Mondrian International Stock Portfolio, a
series of The Travelers Series Trust ("Mondrian International"), pursuant to a
plan of reorganization approved by Mondrian International shareholders on March
14, 2006. The acquisition was accomplished by a tax-free exchange of 12,568,324
Class A shares of Harris Oakmark (valued at $214.8 million) in exchange for the
16,088,645 Class A shares of Mondrian International outstanding on April 28,
2006. Mondrian International Class A net assets at that date ($214.8 million),
including $44,877,012 of unrealized appreciation were combined with those of
Harris Oakmark Class A. The cost of securities acquired in the tax-free
exchange by Harris Oakmark from Mondrian International was $168,917,339. The
aggregate Class A net assets of Harris Oakmark and Mondrian International
immediately before the acquisition were $850,651,198 and $214,792,652,
respectively. The aggregate Class A net assets of Harris Oakmark immediately

10. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

11. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that and there is no
impact to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

PERFORMANCE OVERVIEW

For the six months ended June 30, 2007, the Portfolio outperformed its
benchmark, the S&P 500(R) Index. The Portfolio posted a return of 10.63%, which
compared favorably to the 6.96% return of the benchmark.

PORTFOLIO ATTRIBUTION

Within the Portfolio, holdings within the technology and materials sectors
drove outperformance during the period. In terms of detractors, select consumer
discretionary names were the biggest laggards. Holdings within the telecomm and
financials sectors also weighed on performance.

SECTORS THAT CONTRIBUTED TO PERFORMANCE INCLUDED TECHNOLOGY AND MATERIALS

Within technology, Apple was the top contributor to performance during the
period. Apple gained ground as investors and consumers anxiously awaited the
arrival of the iPhone, which was launched in late June. Investors are sensing
that Apple's original estimate of 10 million phones sold in the first year is
conservative. More importantly, we continue to track market share gains in
desktop and laptop computers, which we think should increase with the launch of
Apple's next generation operating system. Given its recent strength, the stock
could be volatile now that the iPhone has launched. We trimmed the position
slightly but remain constructive on the outlook for the company.

Staying with technology, Research in Motion was also a top-five contributor for
the period, posting solid gains that were highlighted by the addition of
1.2 million new subscribers in its most recent quarter vs. 680,000 during the
same period last year. The company's mobile data service is now offered on over
270 carriers, and subscriber trends remain strong. We remain positive on the
potential of Research in Motion to double its subscriber base over the long
term from the current level of 9 million subscribers as the total addressable
market for mobile data devices continues to expand. Due to our continued
positive outlook for market share gains, we added to the position during the
period.

Within materials, high conviction holding Potash was another top contributor,
driven by realized price increases with important trading partners like India,
which follow previously announced price increases in Brazil and China. Due to
low inventories, pricing for potash should remain robust based on current high
demand trends. We added to the position based on our continued positive outlook
for the company.

SECTORS THAT DETRACTED FROM PERFORMANCE INCLUDED CONSUMER DISCRETIONARY AND
FINANCIALS

Within consumer discretionary, JC Penney declined during the time period after
running up in front of an analyst day it held during the most recent quarter.
Despite the pullback, we remain constructive on the name, viewing the company
as the best-positioned, moderately priced department store in the country. Also
within consumer discretionary, Melco PBL traded down in sympathy with the
decline in Asian markets, which impacted any company with direct exposure to
the Chinese economy. We trimmed the position but remain constructive on the
outlook for this gaming company and its position in the fast-growing Macau
gaming market.

Within financials, Bear Stearns declined during the time period, as it was
weighed down by sub-prime concerns and the bailout of two hedge funds that had
mortgage exposure. While this event helped to illustrate investor fears about
leverage in the system, we maintained exposure to the stock based on its
valuation.

INVESTMENT STRATEGY AND OUTLOOK

Global equity markets have been robust over the past 12 months. Therefore, it
is natural to become apprehensive about the short-term direction of the market
while we await operational confirmation of further economic growth that comes
with time. We believe that rates will remain steady and the Federal Reserve
will remain on the sidelines.

Regardless of the macro-economic climate, we remain focused on identifying
single-purpose business models that are selling compelling products into large
total addressable markets.

+The chart reflects the performance of Class A shares of the Portfolio.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-weighted index (stock price times number of shares outstanding), with
each stock's weight in the Index proportionate to its market value. The Index
does not include fees or expenses and is not available for direct investment.

/2/The Russell 2000(R) Index is an unmanaged index which measures the
performance of the 2,000 smallest companies in the Russell 3000(R) Index, which
represents approximately 8% of the total market capitalization of the Russell
3000(R) Index. As of the latest reconstitution, the average market
capitalization was approximately $898.3 million; the median market
capitalization was approximately $705.4 million. The largest company in the
Index had a market capitalization of $2.5 billion. The Index does not include
fees or expenses and is not available for direct investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gains distributions.

/4/Inception of Class A shares is 03/19/1982. Inception of Class B and Class E
shares is 04/28/2007. Index returns are based on an inception date of 3/31/1982.

/5/"Cumulative Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)


1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Janus Forty Portfolio (formerly Janus
Capital Appreciation Portfolio), which is non- diversified. Shares in the Trust
are not offered directly to the general public and are currently available only
to separate accounts established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B, and E Shares
are offered by the Portfolio. Shares of each Class of the Portfolio represent
an equal pro rata interest in the Portfolio and generally give the shareholder
the same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                    Expiring    Expiring     Expiring    Expiring
Portfolio                Total     12/31/2009  12/31/2010   12/31/2011  12/31/2012

Janus Forty Portfolio $293,010,804 $61,393,522 $74,123,366 $104,924,615 $52,569,301


On May 1, 2006, the Capital Appreciation Fund was reorganized into the Janus
Capital Appreciation Portfolio, a series of Met Investors Series Trust. The
Portfolio acquired capital losses of $338,668,642. The losses incurred by the
Portfolio are subject to an annual limitation of $45,657,838.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. SHORT SALES - The Portfolio may enter into a "short sale" of securities in
circumstances in which, at the time the short position is open, the Portfolio
owns an equal amount of the securities sold short or owns preferred stocks or
debt securities, convertible or exchangeable without payment of further
consideration, into an equal number of securities sold short. This kind of
short sale, which is referred to as one "against the box," may be entered into
by the Portfolio to, for example, lock in a sale price for a security the
Portfolio does not wish to sell immediately.

The Portfolio may also make short sales of a security it does not own, in
anticipation of a decline in the market value of that security. To complete
such a transaction, the Portfolio must borrow the security to make delivery to
the buyer. The Portfolio then is obligated to replace the security borrowed by
purchasing it at market price at the time of replacement. The price at such
time may be more or less than the price at which the

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

security was sold by the Portfolio. Until the security is replaced, the
Portfolio is required to pay to the lender any dividends or interest which
accrue during the period of the loan. To borrow the security, the Portfolio
also may be required to pay a premium, which would increase the cost of the
security sold. The proceeds of the short sale will be retained by the broker,
to the extent necessary to meet margin requirements, until the short position
is closed out. Until the Portfolio replaces a borrowed security, the Portfolio
will segregate with its custodian, or earmark, cash or other liquid assets at
such a level that (i) the amount segregated, or earmarked, plus the amount
deposited with the broker as collateral will equal the current value of the
security sold short and (ii) the amount segregated plus the amount deposited
with the broker as collateral will not be less than the market value of the
security at the time it was sold short. The Portfolio will incur a loss as a
result of the short sale if the price of the security increases between the
date of the short sale and the date on which the Portfolio replaces the
borrowed security. The Portfolio will realize a gain if the security declines
in price between those dates. This result is the opposite of what one would
expect from a cash purchase of a long position in a security. The amount of any
gain will be decreased, and the amount of any loss increased, by the amount of
any premium, dividends or interest the Portfolio may be required to pay in
connection with a short sale. No more than one third of the Portfolio's net
assets will be, when added together: (i) deposited as collateral for the
obligation to replace securities borrowed to effect short sales; and
(ii) segregated in connection with short sales.

H. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

I. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

J. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MANAGED BY LAZARD ASSET MANAGEMENT LLC

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


For the six months ended June 30, 2007, the Lazard Mid-Cap Portfolio Class B
returned 12.41% versus the 9.90% return of the Russell Midcap(R) Index/1/, the
Portfolio's benchmark.

In the beginning of the year, stocks rose modestly, fueled by the combination
of moderating economic growth, solid corporate profits, and strong mergers and
acquisitions activity. Then, a sharp selloff began two days before the end of
February, driving indices to modest losses. While there was no obvious trigger
for the selloff, some analysts pointed to a sharp decline in Chinese shares.
Others blamed the rally in the Japanese yen, which implied that speculators
were reversing the "carry trade." However, stocks recovered much of these
losses in March. Equity markets proved to be resilient in April and May, rising
steadily and ending the first two months of the second quarter with strong
gains. Stocks performed well through May, ignoring a sharp rise in government
bond yields as earnings reports continued to exceed investors' expectations.
Merger activity provided a further boost to stocks. However, stocks experienced
increased volatility in June, as the rise in interest rates accelerated and
investors became increasingly cautious following news of potential hedge fund
losses in the subprime mortgage market. The Federal Reserve decided to leave
interest rates unchanged at the June meeting for the eighth time in the last 12
months, with inflation concerns and sustained economic growth as the main
drivers behind its decision. High commodity prices coupled with a weaker U.S.
dollar and a tight labor market have put pressure on consumer prices,
underscoring the Fed's comment that, "a sustained moderation in inflation
pressures has yet to be convincingly demonstrated." In addition, concerns about
the future of the housing and subprime mortgage markets remain sources of
uncertainty that surround the outlook for the economy. From a sector
perspective, cyclical sectors of the market, such as materials, industrials,
and energy, performed well as economic growth was resilient. Conversely, more
economically defensive groups, such as areas of health care, consumer staples,
and utilities, lagged. Financials were among the worst performing groups, as
uncertainty surrounding the scope of the recent rise in subprime-loan defaults
weighed on the sector.

For the year-to-date-period, performance benefited from solid broad-based stock
selection, in some cases driven by robust corporate activity, as the Portfolio
experienced five takeouts. Stock selection in consumer staples was one of the
largest contributors to outperformance, as shares of Coca-Cola Enterprises,
which bottles and distributes Coca-Cola Company (Coke) products, saw its stock
rise, based on reports that Coke would purchase another beverage company in an
effort to improve its portfolio of products. We believe that this kind of
strategic purchase would significantly benefit Coca-Cola Enterprises. Holdings
such as, Smithfield Foods, Constellation Brands, Kroger, and Pilgrim's Pride
also performed well. In addition, solid

/1/The Russell Midcap(R) Index is an unmanaged index which measures the
performance of the 800 smallest companies in the Russell 1000(R) Index, which
represent approximately 30% of the total market capitalization of the Russell
1000(R) Index. As of the latest reconstitution, the average market
capitalization was approximately $6.3 billion; the median market capitalization
was approximately $4.7 billion. The largest company in the Index had a market
capitalization of $18.3 billion. The Index does not include fees or expenses
and is not available for direct investment.

stock selection in the consumer discretionary sector aided performance, as the
Portfolio's media holdings, including Idearc Inc. and R.H. Donnelley continued
to perform well. However the overall impact in this sector was diminished, as
shares of Liz Claiborne declined. The company reported disappointing earnings,
due to a decline in wholesale-clothing sales to large department stores.
However, we believe the company should benefit from a focus on its more
profitable clothing lines and company-owned stores. Performance was also helped
by stock selection in technology, as Avaya, Solectron, and CDW agreed to be
acquired. Many of the takeout offers in the Portfolio were from private-equity
firms, which show that these strategic buyers are focusing on attractive
valuations and free cash flow. In addition, stock selection in financials
helped returns, as shares of A.G. Edwards rose; Wachovia agreed to buy the
company, creating the second-largest U.S. brokerage firm. Conversely, stock
selection in health care detracted from returns, as shares of Sepracor declined
due to reduced Medicare reimbursement rates for one of its major respiratory
drugs. Returns were also hurt by stock selection in industrials and materials,
as deeper cyclical stocks performed well.

OUTLOOK

While the multiyear rally in equities continues, a change in market leadership
appears to be underway, as investors' risk tolerance moderates after an
extended period of embracing risk. Historically, periods of slowing
corporate-earnings growth have favored more consistently profitable companies,
as investors seek out stability in a more adverse environment. Valuations
remain attractive, earnings visibility is quite strong, and the fundamentals
for owning highly cash-generative stocks are compelling. We believe the
Portfolio is well positioned to benefit from those companies that, from our
perspective, are attractively valued yet offer high returns on capital and high
levels of free cash flow. As a result, we believe the Portfolio should perform
well in these market conditions.

TEAM MANAGED

The Portfolio is managed by Andrew Lacey, Christopher Blake, Gary Buesser and
Robert Failla.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The Russell Midcap(R) Index is an unmanaged index which measures the
performance of the 800 smallest companies in the Russell 1000(R) Index, which
represent approximately 30% of the total market capitalization of the Russell
1000(R) Index. As of the latest reconstitution, the average market
capitalization was approximately $6.3 billion; the median market capitalization
was approximately $4.7 billion. The largest company in the Index had a market
capitalization of $18.3 billion. The Index does not include fees or expenses
and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A shares is 1/2/02. Inception of the Class B shares
is 10/9/01. Inception of the Class E shares is 4/01/02. Index returns are based
on an inception date of 10/9/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

multiplied by the average account value over the period, multiplied by 181/365
(to reflect the one-half year period).

                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Lazard Mid-Cap Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with Lazard Asset Management LLC, (the "Adviser") for investment advisory
services in connection with the investment management of the Portfolio.

Subject to the supervision and direction of the Board, the Manager supervises
the Adviser and has full discretion with respect to the retention or renewal of
the advisory agreement. The Manager pays the Adviser a fee based on the
Portfolio's average daily net assets.

Under the terms of the Portfolio's investment advisory agreement, the Portfolio
pays the Manager a monthly fee based upon annual rates applied to the
Portfolio's average daily net assets as follows:

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES -
CONTINUED


State Street Bank and Trust Company provides custodian and administration
services to the Trust. Effective April 30, 2007, Metropolitan Life Insurance
Company (MLIC) became the new transfer agent for the Trust. MLIC is an
affiliate of the Manager. MLIC receives no fees for its services to the Trust.
Prior to April 30, 2007, State Street Bank and Trust Company served as transfer
agent to the Trust.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a
percentage of the Portfolio's average daily net assets:



                                          Maximum Expense Ratio
                                          under current Expense
                                          Limitation Agreement

                Lazard Mid-Cap Portfolio  0.80%   1.05%   0.95%


If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing
distribution and shareholder servicing with respect to the Class B and Class E
Shares for such entities' fees or expenses incurred or paid in that regard.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MARKET REVIEW AND OUTLOOK

The first half of 2007 saw U.S. equity markets move higher, with the Dow Jones
Industrial Average/1/ and other major stock market indexes exiting the second
quarter just a few percentage points below all-time or multi-year highs. The
catalysts for the advance included strong corporate earnings, abundant
liquidity and a continuation of the strong mergers and acquisitions (M&A)
trends of the past 12 months. During the period, the Federal Reserve ("Fed")/2/
kept short term interest rates unchanged, a sign that Fed members believe we
are in a period of decent, albeit slowing, growth and relatively benign core
inflation. The Dow industrials ended the first half of the year with a 7.6%
gain.

We began the second quarter just weeks removed from the 6% correction in the
major averages of late February/early March. At the end of the first quarter,
we wrote that "whether or not the short and sharp decline seen in the first
quarter will prove the end of the pullback or the beginning of a longer
correction remains to be seen, but we are presently more confident in the
potential for the bull market to proceed apace than we were at the start of the
year."

Perhaps the most encouraging derivative of the strong equity markets in the
second quarter was that the advance was met with increasingly skittish
headlines. Investor concern grew over the rising sub-prime mortgage defaults in
the U.S. and the effect that the backup in long-term interest rates could have
on the future funding of levered transactions. As has been stated often, we
believe a healthy bull market is one that climbs a proverbial "wall of worry,"
and the market of 2007 has so far fit this pattern nicely.

We remain generally constructive in our view toward the equity markets, and our
portfolio holdings in particular. We continue to believe that with corporate
balance sheets flush with cash, we should continue to see stock buybacks,
dividend increases and a proliferation of M&A activity. In fact, it is our view
that the change in administrations in 2008 should only serve to accelerate
large cash transactions amongst corporations. Given this backdrop, we believe
the primary bull market that began in the spring of 2003 is intact, and would
view future pullbacks or corrections in the market constructively.

PORTFOLIO PERFORMANCE REVIEW AND STRATEGY

For the first half of 2007, the Portfolio's relative underperformance compared
with the Russell 3000(R) Growth Index was largely due to stock selection, with
sector selection having only a slightly negative impact on the Portfolio during
the six-month period.

In particular, stock selection in health care was the leading detractor to
Portfolio performance, with stock selection in information technology (IT) and
financials also weighing down relative performance. Sector allocation detracted
the most from performance in health care, cash holdings, IT and industrials.
The Portfolio was significantly overweight in health care and significantly
underweight in IT. Stock selection in energy and industrials were the top
positive contributions to performance during the six month period. The energy
sector, where the Portfolio was significantly overweight, made a positive
contribution to Portfolio performance. It is important to note that the
Portfolio's sector allocation and corresponding over- or underweight positions
were, as usual, effectively a byproduct of the manager's bottom-up, stock
selection process rather than the result of any top-down strategy or questions
of benchmark sensitivity.

Among individual stocks in the Portfolio, Weatherford International Ltd.,
Anadarko Petroleum and Grant Prideco Inc. in the energy sector, and Cablevision
Systems Corp. in consumer discretionary and Tyco International Ltd. in the
industrial sector, contributed positively to performance. The largest
contributors to Portfolio performance in the quarter were our energy sector
holdings in both the service/drilling and exploration/production (E&P)
industries. We view the growth of these businesses as an important trend, which
still may not be fully discounted. The service companies continue to grow
earnings substantially, especially internationally. We also believe it could
prove cheaper for major/national oil companies to acquire reserves on the NYSE
than it would be to drill on their own, which could lift the valuations of the
E&P companies.

Detractors included Amgen Inc., Forest Laboratories Inc., UnitedHealth Group
Inc. in health care, Merrill Lynch & Co. in financials, and Micron Technology
Inc. in IT. The health care and technology holdings suffered from
stock-specific concerns.

In line with our buy-and-hold approach, portfolio turnover during the six-month
period remained low/3/, with the only significant sale being Biosite, a medical
device maker, following the announcement of a proposed acquisition that drove
the company's stock up dramatically in March. Citadel Broadcasting Corp. was
the only significant addition, acquired through Walt Disney Co.'s spin-off of
its ABC Radio assets. As of June 30, the Portfolio was overweight in the health
care, energy and consumer discretionary and financials, and underweight in IT
and industrials. The Portfolio had no substantial holdings in consumer staples,
materials and utilities during the six-month period.

As we have said in the past, our goal is to buy and hold quality companies that
are showing consistent earnings and/or cash flow growth. While we offer our
market/macroeconomic thoughts above, it is the fundamental success or failure
of our companies that will determine the success or failure of our portfolios.
To use a baseball analogy, our goal is to hit for a high average/slugging
percentage, and we believe that to hit a curveball, you need to keep your focus
on the pitch, not the positioning of the fielders.

Keep in mind, the portfolio may invest a significant portion of its assets in
small- and mid-cap companies which may be more volatile than an investment that
focuses only on large-cap companies. The statistics have been obtained from
sources believed to be reliable, but the accuracy and completeness of this
information cannot be guaranteed. Portfolio holdings and characteristics
subject to change.

Limited investments may be made in ADRs and stocks of non-U.S. companies which
involve risks in addition to those ordinarily associated with investing in
domestic securities, including the potentially negative effects of currency
fluctuations, political and economic developments, foreign taxation and
differences in auditing and other financial standards. International investing
may not be suitable for everyone.

    -----------------------------------------------------------------


+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of Class A and E shares
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The Russell 3000(R) Growth Index is an unmanaged index which measures the
performance of those Russell 3000(R) Index companies with higher price-to- book
ratios and higher forecasted growth values. The Index does not include Fees or
expenses and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of Class A shares is 1/2/02. Inception of Class B shares is
2/12/01. Inception of Class E shares is 4/17/03. Index returns are based on an
inception date of 1/31/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Legg Mason Partners Aggressive Growth
Portfolio (formerly Legg Mason Aggressive Growth Portfolio), which is
non-diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:

Legg Mason Partners Aggressive Growth Portfolio $3,178,721 $1,996,340 $1,182,381


Legg Mason Partners Aggressive Growth Portfolio acquired losses of $7,266,413
in the merger with Janus Growth Portfolio on April 28th, 2003 which are subject
to an annual limitation of $1,021,923.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. SHORT SALES - The Portfolio may enter into a "short sale" of securities in
circumstances in which, at the time the short position is open, the Portfolio
owns an equal amount of the securities sold short or owns preferred stocks or
debt securities, convertible or exchangeable without payment of further
consideration, into an equal number of securities sold short. This kind of
short sale, which is referred to as one "against the box," may be entered into
by the Portfolio to, for example, lock in a sale price for a security the
Portfolio does not wish to sell immediately.

The Portfolio may also make short sales of a security it does not own, in
anticipation of a decline in the market value of that security. To complete
such a transaction, the Portfolio must borrow the security to make delivery to
the buyer. The Portfolio then is obligated to replace the security borrowed by
purchasing it at market price at the time of replacement. The price at such
time may be more or less than the price at which the security was sold by the
Portfolio. Until the security is replaced, the Portfolio is required to pay to
the lender any dividends or interest which accrue during the period of the
loan. To borrow the security, the Portfolio also may be required to pay a
premium, which would increase the cost of the security sold. The proceeds of
the short sale will be retained by the broker, to the extent necessary to meet
margin requirements, until the short position is closed out. Until the
Portfolio replaces a borrowed security, the Portfolio will segregate with its
custodian, or earmark, cash or other liquid assets at such a level that (i) the
amount segregated, or earmark, plus the amount deposited with the broker as
collateral will equal the current value of the security sold short and (ii) the
amount segregated plus the amount deposited with the broker as collateral will
not be less

Portfolio will incur a loss as a result of the short sale if the price of the
security increases between the date of the short sale and the date on which the
Portfolio replaces the borrowed security. The Portfolio will realize a gain if
the security declines in price between those dates. This result is the opposite
of what one would expect from a cash purchase of a long position in a security.
The amount of any gain will be decreased, and the amount of any loss increased,
by the amount of any premium, dividends or interest the Portfolio may be
required to pay in connection with a short sale. No more than one third of the
Portfolio's net assets will be, when added together: (i) deposited as
collateral for the obligation to replace securities borrowed to effect short
sales; and (ii) segregated in connection with short sales.

H. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

I. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

J. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held and from changes in the
contract value of forward foreign currency contracts.

K. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

During the six-month period ended June 30, 2007, the Portfolio had a return of
5.10%, versus 0.98% for its benchmark, the Lehman Government/Credit Bond Index,
6.96% for its benchmark S&P 500(R) Index and 6.96% for its benchmark Merrill
Lynch All Qualities, All Convertibles Index.

YOUR PORTFOLIO

The impact of stock selection was positive for the period, led by selection in
the health care and transportation sectors. Stock selection in the retailers
sector was the greatest detractor. The effect of relative sector weightings was
positive, most notably an overweight in energy services and an underweight in
financials--banks.

Our stock selection model performed well for the period, with all of the
dimensions having positive top-to-bottom quintile spreads on an equal weighted
basis. The Technical dimension led in the first quarter, while the Earnings
Growth and Expectations dimensions led in the second quarter.

As of June 30, 2007, your Portfolio remained broadly diversified and
attractively valued compared with the benchmark, with a lower 12-month forward
price-to-earnings ratio ("P/E") and a strong two-year forward earnings growth
rate. Looking forward, your portfolio is focused on stocks that rank
attractively relative to their peers across the dimensions of our stock
selection model.

MARKET ENVIRONMENT

After a positive start to the year, markets globally suffered a correction
towards the end of February, sparked by a sharp one-day decline in local China
A shares. The downturn was exacerbated within the US by sub-prime lending
concerns, with initial reaction centered on the stocks of mortgage lenders. The
second quarter began with benign economic data and strong corporate earnings
until news headlines, involving spikes in bond yields, hedge fund bailouts and
declining home sales, reawakened investors to economic risks. Still, consumer
spending remained stable, industrial growth continued and monetary policy
makers appeared satisfied with the current balance between currency stability
and economic growth. Merger and acquisition activity in the US continued at a
high level, reflecting the global environment.

The leading sectors within the benchmark for the period were energy services,
materials and energy Services as oil process climbed. The only sectors posting
negative returns for the six-month period were financials--banks and
financials--real estate as sub-prime mortgage lending continued to worry
investors.

OUTLOOK

Economic growth has moderated, and the Federal Reserve ("Fed") continues to
monitor signs of inflationary pressure. The consensus outlook for the US
economy therefore remains mostly upbeat, having weathered much of the recent
uncertainty. Our Portfolios are positioned for continued global growth that is
not dependent on the US consumer as the primary source of demand.

INVESTMENT RESEARCH UPDATE

During the period, we completed research on ways to glean additional
information from corporate earnings announcements. As a result, we have
implemented a new Decayed 4-Day Relative Return factor within the Expectations
dimension of our stock selection model. Decayed 4-Day Relative Return
encapsulates earnings information by calculating four-day relative returns
surrounding a company's earnings release. Share-price movement in the days
after an earnings announcement reflects not only earnings data, but also
insights about corporate guidance and future revenues.

We also completed research that furthers our ability to capture shifts in the
distribution of analyst opinions over time so that we can better understand and
exploit changes in market sentiment. As a result, we enhanced the Estimate
Diffusion Factor within our Expectations dimension: we added a second
calculation for this factor that allows us to have a more complete picture of
the distribution of estimates and improves stock count, information ratio and
alpha spreads in peer groups where this factor is applied.

FIXED INCOME

MARKET REVIEW

Bond yields moved higher this year as the economy proved stronger than expected
and expectations of future Fed easing were largely reversed. Long-term rates
rose more than short-term rates, leaving the yield curve almost flat with a
modest positive slope. Core inflation fell within the Fed's comfort zone, but
headline inflation remained elevated and energy prices rose, leaving both the
market and Fed uncertain about future inflation. As bond yields approached the
highs of last year late in the period, signs of stress began to accumulate.
Mortgage-backed spreads widened sharply as extension risk increased and
volatility rose. Swap spreads were driven higher by pressure from
mortgage-backed securities hedging and subprime lending contagion concerns.
Credit spreads were generally tighter, particularly lower-quality spreads,
though they spiked toward the end of the period. Treasury inflation protected
securities' ("TIP") yields rose slightly less than nominal yields, as 10-year
breakeven spreads rose to a modest 2.37%. Emerging market spreads reached
record lows, only to rebound somewhat late in the period. Commodity prices were
generally higher, and gold prices rose modestly. The U.S. dollar fell against
most currencies. Equity markets were generally higher around the world.

CONTRIBUTORS TO PERFORMANCE

Strategies produced mixed results during the period. A tactically driven
duration posture detracted from returns as interest rates rose and duration was
somewhat overweight on average. A modestly bulleted yield curve exposure
contributed to performance as the front end of the curve steepened. Overweight
exposure to the mortgage-backed sector subtracted from returns as spreads
widened. Underweight

exposure to investment grade credits was a negative as the sector outperformed,
but an overweight exposure to lower quality credits was rewarded as spreads
tightened. A moderate exposure to TIPS contributed to performance, due mainly
to a larger than expected inflation adjustment, which in turn was primarily
driven by rising energy prices.

OUTLOOK AND STRATEGY

Markets fret and pundits pontificate. However, despite a list of concerns that
includes recession, inflation, a plunging U.S. housing market, a soaring U.S.
current account deficit, the collapse of subprime lending, and a surge in
leveraged buyouts, the global financial environment has probably never been so
healthy and relatively calm. Interest and inflation rates in most major
economies haven't been so low and stable for many decades. The implied
volatility of stock and bond options has been exceptionally low for the past
several years, and credit spreads are generally low and stable. The volatility
that we have seen has been relatively contained, and interest rates have
generally moved in a narrow and slight upward sloping range for the past few
years. Free markets are working their wonders in China and India, and rapidly
expanding global trade is boosting the efficiency of all but a handful of
nations. As a result, global living standards are improving significantly and
more people are upwardly mobile than at any other time in history. Not
surprisingly, equity markets are moving steadily higher in nearly every
industrialized and emerging market economy.

Of the many contributing factors to global prosperity, a prevailing pessimism
is one of the lesser remarked factors. The memory of the stock market collapse
of 2000-2002 is still fresh, terrorist threats are real, the U.S. housing
market has yet to bottom out, hedge funds are stumbling, and central banks are
still finding reasons to raise interest rates. If bull markets can climb walls
of worry, then the good times will likely continue.

The recent spike in interest rates in most markets is the latest concern to
investors. However, it too stems from pessimism. Good economic news in recent
months has challenged investors' gloomy outlook for the U.S. economy, so Fed
rate cuts now are considered to be significantly less likely. In recent years,
central banks tended to overestimate the risks of deflation and underestimate
the potential for economic growth, so their pessimism resulted in monetary
policy that was probably easier than it should have been. Easy money has helped
fuel demand and keep inflation and interest rates higher than they might
otherwise have been.

Leaving headlines aside, it's hard to find evidence of any major threats to
growth. Most recessions have been caused by a substantial tightening of
monetary policy, which is typically a response to a real or perceived inflation
threat. However, real interest rates are not particularly high in any major
economy, and inflation is generally contained. Fiscal policy is supportive
overall, and while Democrats seem anxious to raise taxes, the rapidly shrinking
U.S. federal budget deficit significantly mitigates that risk. The U.S. housing
market has yet to bottom out, but there are signs that the worst of
construction declines is behind us. Thus, the drag from housing should lessen
in the future. Ongoing strength in industrial commodity prices is evidence of
the vitality of the global economy.

At the same time, it's hard to envision the U.S. economy becoming strong enough
to sound alarms at the Fed. Job growth has been quite modest, and productivity
has fallen substantially. We can't dismiss the possibility of further
deterioration in the housing market, especially in light of the 50 bps rise in
mortgage rates over the past three months and the virtual cessation of subprime
lending activity. The economy is currently rebounding from a soft first
quarter, but seems unlikely to grow more than 2-3% over the next year.

We are continuing to pursue a tactical duration policy which calls for
increased duration as rates rise, and reduced duration as rates fall. We
believe rates are likely to oscillate in a relatively stable range, and should
decline from recent highs as investor jitters subside. Long-term yields are
likely to be less volatile than short-term yields, since they appear to be
anchored by inflationary pressures that are reasonably contained. The curve is
likely to flatten on continued economic strength, or to steepen on any signs of
weakness. Thus, an overweight exposure to short-term rates should be a good
hedge against our overweight exposure to lower quality credits.

Our primary sector overweight exposure is to mortgage-backed securities, since
they should benefit from stable interest rates and reduced volatility. In
addition, the recent upward drift in spreads has made this sector generally
attractive. With credit spreads generally low, we are targeting an underweight
exposure to the sector overall, with an overweight exposure to lower quality
credits where spreads are still somewhat attractive. We are mindful of growing
downside risks, and concerned about the increased level of takeovers and
leveraged buyout activity, since these factors undermine fundamental credit
quality. We like TIPS as an inflation hedge, and have increased our exposure as
real yields have reached attractive levels.

CONVERTIBLE

MARKET REVIEW

The continuing correction in the U.S. housing market combined with the
surprisingly weak business investment spending resulted in an anemic growth
rate of 0.7% in US GDP in the first quarter of 2007. Fortunately, the U.S.
consumer remains resilient as employment growth continues, and with an
improvement in the trade balance and an uptick in business investment the
second quarter, yet to be reported, seems likely to have picked up the pace.

MARKET OUTLOOK

Housing remains the weak spot in the economic picture, clearly the victim of
the last cycle of rising interest rates conducted by the Federal Reserve, but
while it will obviously take some time for the large inventory of both new and
existing homes to be cleared, the drag on economic growth from this sector
seems likely to slowly decline going into the second half of 2007 and 2008.

accelerating and gains in financial assets offsetting the decline in home
values, consumers remain in good shape and are likely to cope with yet another
rise in energy prices.

The convertible market has performed admirably for the first half of 2007, but
if our expectation of a strong finish to the year by stock prices proves to be
correct convertibles will likely lag behind, particularly if the recent
widening of credit spreads in the fixed income market continues. Remember that
convertibles typically offer higher current income but less appreciation
potential than stocks, and greater appreciation potential and less current
income than bonds.

PORTFOLIO PERFORMANCE REVIEW AND STRATEGY

The industrial sector, which was the largest sector holding at June 30, 2007,
was the top group contributor to Portfolio returns for the period. This
performance was led by the convertible bonds of Actuant Corp., a manufacturer
of a broad range of industrial products and systems, and by the convertible
bonds of United Rentals, an equipment rental company.

The second largest group contributor to Portfolio returns for the first half of
2007 was the information technology sector. This group was led by our holdings
in Sina Corp., an online media and information services provider that serves
China and Chinese-language communities worldwide, and by Corning Inc., a
fiber-optic technology company.

The largest detractor from Portfolio returns for the six-month period was the
financials sector, led by holdings in Merrill Lynch & Co., a provider of
financial services, and Countrywide Financial Corp., a holding company engaged
in financial services, including mortgage lending.

The second worst performing group in the Portfolio was the materials sector,
one of the smallest sectors in the Portfolio, where our two holdings, Pioneer
Cos., a chemicals company, and Headwaters Inc., a diversified company serving
the energy and construction industries, ended the first half of the year with
no gain or loss.

+The chart reflects the performance of Class A shares of the Portfolio. This is
currently the only active Class in the Portfolio.

/1/The Lehman Brothers Government/Credit Bond Index is a weighted composite of
the Lehman Brothers Government Bond Index, which is a broad-based index of all
public debt obligations of the U.S. Government and its agencies and has an
average maturity of nine years and the Lehman Brothers Credit Bond Index, which
is comprised of all public fixed-rate non-convertible investment grade domestic
corporate debt, excluding collateralized mortgage obligations. The Index does
not include fees or expenses and is not available for direct investment.

/2/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-weighted index (stock price times number of shares outstanding) with
each stock's weight in the Index proportionate to its market value. The Index
does not include fees or expenses and is not available for direct investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gains distributions.

/4/Inception of Class A shares is 4/08/1983. Index returns are based on an
inception date of 4/30/1983.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Legg Mason Partners Managed Assets
Portfolio, which is diversified. Shares in the Trust are not offered directly
to the general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A Shares are offered
by the Portfolio. Class B and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. FORWARD COMMITMENTS, WHEN-ISSUED AND DELAYED DELIVERY SECURITIES - The
Portfolio may purchase securities on a when-issued or delayed delivery basis
and may purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the purchase
or sale commitment is made. The Portfolio may purchase securities under such
conditions only with the intention of actually acquiring them, but may enter
into a separate agreement to sell the securities before the settlement date.
Since the value of securities purchased may fluctuate prior to settlement, the
Portfolio may be required to pay more at settlement than the security is worth.
In addition, the purchaser is not entitled to any of the interest earned prior
to settlement. Upon making a commitment to purchase a security on a
when-issued, delayed delivery or forward commitment basis, the Portfolio will
hold liquid assets in a segregated account at the Portfolio's custodian bank
worth at least the equivalent of the amount due. The liquid assets will be
monitored on a daily basis and adjusted as necessary to maintain the necessary
value.

I. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


J. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees

accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES -
CONTINUED


If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the

respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

As of December 31, 2006, the components of distributable earnings (accumulated

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

ECONOMIC OVERVIEW & OUTLOOK

Equity markets powered higher during the first six months of 2007, shrugging
off continued concerns about subprime lending in particular and the U.S.
housing market in general, as well as a correction in late February and early
March. The S&P 500(R) Index returned 6.96% during the two quarters, while the
Russell 2000(R) Index/1/ of small caps returned 6.45%, a reversal of the last
few years of small cap dominance. From a style perspective, the Russell 1000(R)
Growth Index/2/ returned 8.13% versus 6.23% for the Russell 1000(R) Value
Index/3/, also a turnaround from recent patterns.

Economic growth and corporate profits slowed but remain solidly in positive
territory. Although the Fed continues to profess a hawkish bias, inflation
worries have thankfully begun to recede. The rate cuts that many were expecting
at the beginning of the year, however, are now looking less and less likely. We
believe U.S. economic growth, softened by a downturn in the housing market,
will continue to be slow but positive for the rest of 2007. Given strong
employment levels and healthy corporate profits, the likelihood of a recession
remains remote, in our view.

The new year continued the "game change" that has been evident since early
August 2006, as traditional growth stocks outperformed value, and large caps
posted better results than smaller issues. Our U.S. equity market outlook
remains unchanged since the beginning of the year. We continue to expect equity
returns in the mid-teens based on a favorable economic backdrop that should
support solid earnings growth and dividends, benign monetary policy (recent
rises in bond yield notwithstanding), and attractive valuations that leave room
for a point or so of multiple expansion.

PORTFOLIO OVERVIEW

For the six months ended June 30, 2007, the Portfolio posted a total return of
5.06% for Class B, underperforming the 6.96% return of the

/1/ The Russell 2000(R) Index is an unmanaged index which measures the
performance of the 2,000 smallest companies in the Russell 3000(R) Index, which
represents approximately 8% of the total market capitalization of the Russell
3000(R) Index. As of the latest reconstitution, the average market
capitalization was approximately $898.3 million; the median market
capitalization was approximately $705.4 million. The largest company in the
index had a market capitalization of $2.5 billion. The Index does not include
fees or expenses and is not available for direct investment.

/2/ The Russell 1000(R) Growth Index is an unmanaged index that measures the
performance of those Russell 1000 companies with higher price-to-book ratios
and higher forecasted growth values. The Index does not include fees or
expenses and is not available for direct investment.

/3/ The Russell 1000(R) Value Index is an unmanaged index which measures the
performance of the Russell 1000(R) Index companies with lower price-to-book
ratios and lower forecasted growth values. The Index does not include fees or
expenses and is not available for direct investment.

benchmark S&P 500(R) Index. Large stakes in weak-performing securities in the
information technology, consumer discretionary, health care and
telecommunication sectors were among the largest detractors from returns. Our
absence from the strong-performing energy sector also weighed meaningfully on
relative performance.

From an individual security perspective, Amazon.com took off after reporting an
unexpectedly impressive first quarter that saw sequential margin expansion,
increased full-year profit guidance, and a $500 million share repurchase. Other
Internet holdings Expedia and Google also posted solid gains. Sprint Nextel,
which performed poorly in 2006, made up some lost ground in the first half of
2007, as pressure from activist investors seems to have helped light a fire
under the struggling company. Managed care organizations Aetna and Health Net
also helped portfolio performance, as medical cost trends appear to be tipping
back in their favor. On the downside, concerns about the sickly housing market,
especially during the market's volatile first quarter, caused housing-related
companies to perform poorly. Although the six stocks--Countrywide Financial,
Centex, Pulte Homes, Beazer Homes, Ryland, and Home Depot--together represent
only about 10% of the portfolio, their combined performance accounted for the
lion's share of drag on overall returns. Most of the downturn was concentrated
in February and March, and the group was able to make up some lost ground in
the second quarter. Seagate Technology suffered following an April earnings
release showing a weaker-than-expected demand environment and
higher-than-expected price competition among desktop class drives. Meanwhile,
expected synergies and lower intensity of competition from the Maxtor deal have
yet to fully materialize.

We are optimistic about the portfolio for the rest of 2007 and beyond. We
continue to believe that our disciplined, fundamental, bottom-up,
valuation-focused process will, over the long-term, produce competitive
results, and we thank investors for their continued trust and confidence.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B shares
because of the difference in expenses paid by policyholders investing in the
different share class.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-value weighted index (stock price times number of shares outstanding),
with each stock's weight in the Index proportionate to its market value. The
Index does not include fees or expenses and is not available for direct
investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of Class A and Class B shares is 11/1/05. Inception of Class E
shares is 5/1/06. Index returns are based on an inception date of 10/31/05.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Legg Mason Value Equity Portfolio, which
is non-diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Trust's Valuation
Committee. The Valuation Committee will regularly monitor and review the
services provided by the pricing service to the Portfolios and periodically
report to the Board on the pricing services' performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

G. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

H. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

I. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


Portfolio enters into a repurchase agreement, the value of the collateral
securities including accrued interest will be equal to or exceed the value of
the repurchase agreement and, for repurchase agreements that mature in more
than one day, the seller will agree that the value of the collateral securities
including accrued interest will continue to be at least equal to the value of
the repurchase agreement.

J. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the

State Street Bank and Trust Company provides custodian and administration
services to the Trust. Effective April 30, 2007, Metropolitan Life Insurance
Company (MLIC) became the new transfer agent for the Trust. MLIC is an
affiliate of the Manager. MLIC receives no fees for its services to the Trust.
Prior to April 30, 2007, State Street Bank and Trust Company served as transfer
agent to the Trust.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a
percentage of the Portfolio's average daily net assets:

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. ACQUISITIONS

On May 1, 2006, Legg Mason Value Equity Portfolio ("Value Equity") acquired all
of the net assets of MFS Investors Trust Portfolio, a series of Metropolitan
Series Fund, Inc., ("MFS Investors") pursuant to a plan of reorganization
approved by MFS Investors shareholders on March 14, 2006. The acquisition was
accomplished by a tax-free exchange of 5,304,737 Class A shares of Value Equity
(valued at $56.0 million) in exchange for the 5,954,932 Class A shares of MFS
Investors, 4,919,414 Class B shares of Value Equity (valued at $51.9 million)
in exchange for the 5,505,682 Class B shares of MFS Investors and 2,226,012
Class E shares of Value Equity (valued at $23.5 million) in exchange for the
2,496,689 Class E shares of MFS Investors. MFS Investors Class A net assets at
that date ($56.0 million), including $7,451,570 of unrealized appreciation were
combined with those of Value Equity Class A. MFS Investors Class B net assets
at that date ($51.9 million), including $7,423,569 of unrealized appreciation
were combined with those of Value Equity Class B. MFS Investors Class E net
assets at that date ($23.5 million), including $3,153,729 of unrealized
appreciation were combined with those of Value Equity Class E. The cost of
securities acquired by Value Equity from MFS Investors was $113,318,381. The
aggregate Class A net assets of Value Equity and MFS Investors immediately
before the acquisition were $3,153,591 and $55,964,976, respectively. The
aggregate Class A net assets of Value Equity immediately after the acquisition
were $59,118,567. The aggregate Class B net assets of Value Equity and MFS
Investors immediately before the acquisition were $29,399,561 and $51,850,624,
respectively. The aggregate Class B net assets of Value Equity immediately
after the acquisition were $81,250,185. The aggregate Class E net assets of
Value Equity and MFS Investors immediately before the acquisition were $10,000
and $23,484,428, respectively. The aggregate Class E net assets of Value Equity
immediately after the acquisition were $23,494,428.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

EQUITY OVERVIEW

MARKET & ECONOMIC REVIEW AND OUTLOOK

The market had a volatile first quarter, as investors worried about the pace of
economic activity. It rebounded from a difficult February to post a positive
return in March and for the first quarter. In March, investors had more
confidence that economic activity would continue to be reasonably strong, and
the Federal Reserve seemed to signal a softer stance toward rate increases,
thus resulting in a rebound in the stock markets.

The market was surprisingly buoyant in the second quarter. Bad news on the
subprime mortgage and housing fronts was absorbed with little indigestion and
bumpy economic statistics were shrugged off, as investors focused on strong
earnings growth and the ebullient merger and acquisition climate. We wouldn't
be surprised to see the market consolidate its gains in the near-term, but it
remains poised to deliver high single-digit, low double-digit gains for the
year. The backdrop: solid profit growth, constructive valuation levels and a
reasonable inflation/interest rate environment, may augur well for a healthy
market. We are watching global liquidity levels, as this continues to be a key
market lynchpin, but with no real change expected on this front, we remain
optimistic about market prospects for the balance of the year.

PORTFOLIO PERFORMANCE REVIEW

Within this environment, the equities sleeve of the Portfolio outperformed its
benchmark, the MSCI World Index/SM/, returning +11.1% versus +9.5% for the
Index. Strong returns were due in large part to positive stock selections
across all sectors, as there were no sectors that detracted from performance
for the first half of the year. Leading the pack in contribution to return were
technology and financials names.

The technology sectors' performance was due primarily to Apple. Apple continued
to benefit from the anticipation of the iPhone, which had an early summer
release, the introduction of its iTV service, and strong sales of its iPod and
iMac line-up. Financials performed well due to the performance of Keppel Land
and Piraeus Bank. Keppel Land, a Singapore real estate company shares rose in
February, as a potential shortage of office space in the downtown area of
Singapore has been driving rents higher. Piraeus Bank shares rose after it was
reported that Dubai Investment Group LLC might make a bid for the bank and
offer as much as seven billion euros.

FIXED INCOME OVERVIEW

MARKET AND ECONOMIC REVIEW AND OUTLOOK

The US dollar weakened and global Treasury yields rose in the first half of
2007. Perceptions of a "strong Eurasia, weak US" have shifted towards "strong
Eurasia, strong US." Investors largely ignored friendlier data on core
inflation, which has declined in the US to within the Federal Reserve's target
range, and have instead focused on rising commodity prices. Treasurys only
briefly rallied in late June in reaction to subprime mortgage and hedge fund
stresses. In general, we continue to expect a robust global economy, higher
central bank policy rates abroad, and stable policy rates in the US. Bond
yields may find their way irregularly higher over time. Among currencies, the
US dollar and Japanese yen are near recent valuation lows, and the Euro and
currencies such as the Canadian dollar and Australian dollar are near decade
highs. We retain a preference for non-Japanese Asian currencies as we expect
fast Asian economic growth to continue.

PORTFOLIO PERFORMANCE REVIEW

The fixed income sleeve of the Portfolio outperformed its benchmark, the
Citigroup World Government Bond Index/1/, returning 2.23%, versus a 0.41% loss
for the Index. At the total Portfolio level, the Portfolio remained heavily
tilted towards equities, which have strongly outperformed bonds. The main
drivers of fixed income gains were exposure to smaller foreign currency markets
such as Colombia, Iceland and Brazil, and selected U.S. high yield and
investment grade corporate issues. The weakest segments of the Portfolio's
fixed income sleeve were our positions in Malaysian Ringgit and Japanese yen.

Top and bottom returns were either currency or company specific. Top performers
included an Avnet convertible bond, a Rabobank issue in Icelandic krona, and a
Merrill Lynch issue in Brazilian real. Our worst performers included the debt
of SLM Corp (Sallie Mae), which was taken private; Hovnanian, which has
weakened with the slump in new home sales and Canadian paper-maker Abitibi,
which has been hurt by Canadian dollar strength and weak pulp sales.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B shares
because of the difference in expenses paid by policyholders investing in the
different share class.

/1/The MSCI World Index/SM/ is an unmanaged free-float adjusted market
capitalization index that is designed to measure global developed market equity
performance. The Index does not include fees or expenses and is not available
for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of Class A and Class B shares is 5/1/06. Index returns are based
on an inception date of 4/30/06.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                           JUNE 30, 2007 (UNAUDITED)


1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Loomis Sayles Global Markets Portfolio,
which is diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                             Expiring
         Portfolio                                 Total    12/31/2014
         ---------                              ----------- -----------
                                                      

         Loomis Sayles Global Markets Portfolio $18,067,159 $18,067,159


E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

G. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

H. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

I. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

J. FORWARD COMMITMENTS, WHEN-ISSUED AND DELAYED DELIVERY SECURITIES - The
Portfolio may purchase securities on a when-issued or delayed delivery basis
and may purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the purchase
or sale commitment is made. The Portfolio may purchase securities under such
conditions only with the intention of actually acquiring them, but may enter
into a separate agreement to sell the securities before the settlement date.
Since the value of securities purchased may fluctuate prior to settlement, the
Portfolio may be required to pay more at settlement than the security is worth.
In addition, the purchaser is not entitled to any of the interest earned prior
to settlement. Upon making a commitment to purchase a security on a
when-issued, delayed delivery or forward commitment basis, the Portfolio will
hold liquid assets in a segregated account at the Portfolio's custodian bank
worth at least the equivalent of the amount due. The liquid assets will be
monitored on a daily basis and adjusted as necessary to maintain the necessary
value.

K. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MARKET REVIEW

Economic data during the period was mostly positive, with employment, wages,
and consumer confidence all strong. First quarter Gross Domestic Product (GDP)
growth, however, fell to 0.7%, the slowest growth level in four years. Within
the disappointing GDP report, the housing market was especially weak with
existing home sales slowing in April and May to an annualized rate of 5.99
million. With mixed data and relatively low inflation, the Federal Reserve
Board (the Fed) left the Fed Funds rate (the rate at which banks lend to one
another) unchanged at 5.25% at its January, March, May, and June meetings. At
the last meeting, the Fed indicated that the U.S. economy continued to grow at
a moderate pace but that "the predominant policy concern remains the risk that
inflation will fail to moderate as expected". Late in the period, the benchmark
10-year Treasury yield crossed the psychologically important level of 5% for
the first time since August of 2006, increasing to 5.295% on June 12/th/, the
highest level in five years.

Year-to-date, the Merrill Lynch High Yield Master II Index is up 3.07%, the
Lehman Aggregate Index is up 0.98%, and the Merrill Lynch All Convertibles
Index/(1)/ is up 6.96%. Convertibles captured 100% of the upside of equities,
with the S&P 500(R) Index/(2)/ also up 6.96%.

Thus far in 2007, investors have shown a preference for riskier, lower rated
securities. Within the high yield market, CCC-rated bonds outperformed single
and double B-rated bonds, with the CCC-Index up 6.14%, the B-Index up 3.34%,
and the BB-Index up 1.54%. In the convertible market, speculative grade issues
beat investment grade issues as well. The Merrill Lynch Speculative Grade
Index/(3)/ was up 9.83%, while the Merrill Lynch Investment Grade Index/(4)/
was up 5.46%. Even in the high-grade portion of the market, mortgages and
corporates outperformed treasuries.

PORTFOLIO REVIEW

The Portfolio outperformed its benchmark, the Lehman Brothers Aggregate Bond
Index, for the six months ended June 30, 2007.

Performance during the period was helped by convertible securities, which
greatly outperformed high yield and high grade holdings. These securities
benefited from positive macro trends and a strong equity market. Among
industries, pharmaceuticals, health services, and media-cable were particularly
strong. In particular, Schering-Plough Corporation did well after releasing
first quarter results which heartily beat analyst expectations. Additionally,
other pharmaceutical companies also were boosted by stronger than anticipated
sales growth. In health services, Manor Care, Inc. rose sharply on a possible
private equity buyout. Natural gas provider, The Williams Companies, Inc. was
also among top performers.

The company agreed to sell its power assets in a move to reduce debt and focus
on its core natural gas operations. The move should also lead to a lower cost
of capital for the firm.

Detracting from performance on an absolute basis were high grade holdings,
which lagged high yield and convertibles as interest rates rose over the period
and riskier assets performed better. In particular, the more interest rate
sensitive industries of investments and banking lagged. Also detracting from
performance was beverage company, Constellation Brands, Inc. The company
disappointed investors after lowering guidance for 2008, citing increasing
challenges in the UK market, primarily due to increased competition from low
cost Australian and private label wine makers. Agriculture firm,
Archer-Daniels-Midland Company, also detracted from performance after the firm
released lower than expected quarterly earnings. The company missed targets on
ethanol margins, partly due to higher corn costs. Chip maker, LSI Corporation,
also detracted from performance after the company gave guidance for second
quarter sales and profit that fell short of analyst expectations. The guidance
also led to investor worries over a recent large acquisition made by the firm.

OUTLOOK

We do not think that recent difficulties in the subprime mortgage market will
spill over into the U.S. high yield market and we have avoided subprime issuers
within our mortgage holdings. We believe much of the problem stems from
aggressive issuance and low lending standards and we have always maintained a
preference for AAA rated prime mortgages. Nevertheless, we think that investors
have become more cautious given the subprime shock and that market volatility
could continue for several more quarters. We remain positive on the outlook for
high yield. We were pleased with first quarter earnings among our holdings and
expect corporate earnings to continue growing at a high single digit pace.

We have been saying from some time that inflation would be constrained and that
Treasuries have not offered compelling value. We have seen that play out thus
far this year, with high yield and convertibles greatly outperforming
investment grade securities. We expect strength in capital goods, energy,
infrastructure, and select export markets and are avoiding high yield issuers
that are closely tied to low end consumer spending. Convertible securities have
also been an important factor this year and we have seen good earnings results
from many of the convertibles we hold. Interest rates may continue to trend
higher, but we expect that GDP growth will eventually normalize to the 2% range.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B and Class E
shares because of the difference in expenses paid by policyholders investing in
the different share class.

/1/Lehman Brothers Aggregate Bond Index represents securities that are U.S.
domestic, taxable, non-convertible and dollar denominated. The Index covers the
investment grade fixed rate bond market, with index components for government
and corporate securities, mortgage pass-through securities, and asset-backed
securities. The Index does not include fees or expenses and are not available
for direct investment.

/2/The Credit Suisse First Boston High Yield Index is an unmanaged index
representative of lower rated debt, including straight-preferred stocks. The
Index does not include fees or expenses and is not available for direct
investment.

/3/The Merrill Lynch High Yield Master II Constrained Index and the Hybrid
Index is comprised of 60% Merrill Lynch High Yield Master II Constrained Index,
20% Lehman Brothers U.S. Aggregate Bond Index, 20% Merrill Lynch all
Convertible Index. The Index does not include fees or expenses and are not
available for direct investment.

/4/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/5/Inception of the Class A shares is 5/1/96. Inception of the Class B shares
is 4/3/01. Inception of the Class E shares is 4/2/02. Index returns are based
on an inception date of 5/1/96.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Lord Abbett Bond Debenture Portfolio,
which is diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:

     Lord Abbett Bond Debenture Portfolio $8,332,196 $4,020,940 $4,311,256


Lord Abbett Bond Debenture Portfolio acquired losses of $19,627,064 in the
merger with Loomis High Yield Fund on April 26, 2002, which are subject to an
annual limitation of $3,688,483.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. FORWARD COMMITMENTS, WHEN-ISSUED AND DELAYED DELIVERY SECURITIES - The
Portfolio may purchase securities on a when-issued or delayed delivery basis
and may purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the purchase
or sale commitment is made. The Portfolio may purchase securities under such
conditions only with the intention of actually acquiring them, but may enter
into a separate agreement to sell the securities before the settlement date.
Since the value of securities purchased may fluctuate prior to settlement, the
Portfolio may be required to pay more at settlement than the security is worth.
In addition, the purchaser is not entitled to any of the interest earned prior
to settlement. Upon making a commitment to purchase a security on a
when-issued, delayed delivery or forward commitment basis, the Portfolio will
hold liquid assets in a segregated account at the Portfolio's custodian bank
worth at least the equivalent of the amount due. The liquid assets will be
monitored on a daily basis and adjusted as necessary to maintain the necessary
value.

8. ACQUISITIONS

On May 1, 2006, Lord Abbett Bond Debenture Portfolio ("Bond Debenture")
acquired all of the net assets of Convertible Securities Portfolio, a series of

Class A shares of Bond Debenture (valued at $100.2 million) in exchange for the
8,068,461 Class A shares of Convertible Securities outstanding on April 28,

including $6,800,593 of unrealized appreciation were combined with those of
Bond Debenture Class A. The cost of securities acquired in the tax-free
exchange by Bond Debenture from Convertible Securities was $93,008,142. The

the acquisition were $785,793,046 and $27,175,078, respectively. The aggregate
Class B net assets of Bond
Debenture immediately after the acquisition were $812,968,124.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MARKET REVIEW

Supported by above-trend earnings growth and a dwindling supply of shares
outstanding, equities returned approximately 7% (on a total return basis) in
the six-month period ended June 30, 2007. Though the path higher had its dips
and turns, both the Dow Jones Industrial Average/1 /and S&P 500(R) Index
reached record levels, with the latter finally cresting (albeit for only a
brief period) its prior high established seven years ago. A bevy of mergers and
acquisitions, private equity deals, and share buybacks cumulatively left
investors with fewer shares of public companies to own.

The industrial sector of the economy looked stronger in the period. With the
supply of inventories low and foreign demand robust, manufacturing activity
began to accelerate. The Institute for Supply Management's (ISM) survey of the
manufacturing sector, for instance, jumped 4.1 points between March and May. In
response, year-ahead forward rates on three-month deposits rose, and the yield
on the 10-year Treasury bond climbed lockstep. By early June, the rise in the
10-year Treasury bond yield eclipsed that of short-term rates, which triggered
a period of consolidation in the equity markets. Though the semiannual period
ended June 30, 2007 finished on a down-note, the gains returned during the full
period were still quite strong.

Returns in the equity market were broad; however, companies with mid to small
capitalizations outperformed large to mega capitalizations. In fact, shares of
growth-oriented small and mid cap companies led all other styles of investing.
The relative strength of small and mid caps reflected the large number of
private equity deals (reportedly worth more than $300 billion) announced
between January and June 2007. With the performance of large cap companies
trailing that of their smaller peers, the valuation gap (the difference between
the prices that investors are willing to pay for the earnings of the companies
in each index) widened. At the close of June, the price-to-earnings ratio (P/E)
of the S&P 100(R) Index/2/ was about 25% less than the P/E of the small and mid
cap indexes. Finally, unlike in the small and mid cap categories, value
continued its dominance over growth in the large cap space.

PORTFOLIO REVIEW

The largest detractor from the performance relative to the S&P 500(R) Index/3/
was stock selection within the technology sector. The Portfolio lacked exposure
to Apple, an S&P 500(R) Index holding that continues to outperform, owing to
product introductions like the iPhone. The Portfolio's underweight of the other
energy and integrated oils sectors also detracted, as both sectors advanced
nicely during the six-month period, benefiting from the price of crude oil.
Although prices began the year with a rapid sell-off to below $60 per barrel,
they subsequently rallied strongly to end on a high note in June, topping $70
per barrel--a level still below that of a year ago.

Conversely, stock selection within the consumer staples sector aided relative
performance, with Kroger performing well during the period. This large grocery
store chain solidified its competitive position in the marketplace, allowing it
to better withstand competition from giant retailers such as Wal-Mart. Lastly,
stock selection within the health care sector aided relative performance, with
pharmaceutical companies Baxter and Teva outperforming for the period. Baxter
benefited from the positive resolution of issues regarding its infusion pump.
Generic drug manufacturer Teva reported better than expected fourth quarter
2006 earnings and guided current year earnings higher.

OUTLOOK

We continue to increase our exposure to the technology sector. The glut of tech
capacity put in place in the late 1990's has been largely absorbed, and tech
companies are now well positioned to take advantage of increased infrastructure
spending.

We remain overweight consumer staples, continuing to concentrate on stable
earners that can grow earnings in a slowing economic environment through new
products and/or restructuring. We also took profits in several positions
that have performed well over the past couple of years. The health care
overweight was reduced, as we trimmed exposure to large pharmaceutical
companies that have performed well and thus represented attractive
profit-taking opportunities. We also decreased our exposure to
utilities, taking advantage of the strong performance in this sector over the
past year.

We continue to underweight financial services, especially in regional banks, as
we believe that banks are earning at above normal levels with prospects for an
upswing in problem loans (from historically low levels). Recent sub-prime
lending woes are a harbinger of more difficulties ahead. We remain underweight
integrated oils, as crude oil prices remain above long term normalized levels
and current earnings levels are not sustainable, in our opinion.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B shares
because of the difference in expenses paid by policyholders investing in the
different share class.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-value weighted index (stock price times number of shares outstanding),
with each stock's weight in the Index proportionate to its market value. The
Index does not include fees or expenses and is not available for direct
investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A shares is 12/11/89. Returns shown for the Class A
shares are the historical returns of the Lord Abbett Growth & Income Portfolio
of Cova Series Trust (from January 8, 1999 through December 31, 2000) and of
the Growth and Income Portfolio of Lord Abbett Series Fund, Inc. (from December
11, 1989 through January 7, 1999). Inception of the Class B shares is 3/22/01.
Index returns are based on an inception date of 12/11/89.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Lord Abbett Growth and Income Portfolio,
which is diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                     Expiring   Expiring    Expiring

Lord Abbett Growth and Income Portfolio $46,237,772 $8,374,531 $28,690,142 $9,173,099


Lord Abbett Growth and Income Portfolio acquired losses of $61,902,713 in the
merger with J.P. Morgan Enhanced Index Portfolio on April 28th, 2003 which are
subject to an annual limitation of $5,221,647.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

8. ACQUISITIONS

On May 1, 2006, Lord Abbett Growth and Income Portfolio ("Growth and Income")
acquired all of the net assets of Federated Stock Portfolio, a series of The
Travelers Series Trust ("Federated Stock"), pursuant to a plan of
reorganization approved by Federated Stock shareholders on March 14, 2006. The
acquisition was accomplished by a tax-free exchange of 1,016,486 Class B shares
of Growth and Income (valued at $27.3 million) in exchange for the 1,773,115
Class A shares of Federated Stock outstanding on April 28, 2006. Federated
Stock Class A net assets at that date ($27.3 million), including $2,884,780 of
unrealized appreciation were combined with those of Growth and Income Class B.
The cost of securities acquired in the tax-free exchange by Growth and Income
from Federated Stock was $24,155,155. The aggregate Class B net assets of
Growth and Income and Class A of Federated Stock immediately before the
acquisition were $1,196,462,432 and $27,312,987, respectively. The aggregate
Class B net assets of Growth and Income immediately after the acquisition were
$1,223,775,419.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MARKET REVIEW

Supported by above-trend earnings growth and a dwindling supply of shares
outstanding, equities returned approximately 7% (on a total return basis) in
the six-month period ended June 30, 2007. Though the path higher had its dips
and turns, both the Dow Jones Industrial Average/(1) /and S&P 500(R) Index/(2)/
reached record levels, with the latter finally cresting (albeit for only a
brief period) its prior high established seven years ago. A bevy of mergers and
acquisitions, private equity deals, and share buybacks cumulatively left
investors with fewer shares of public companies to own.

The industrial sector of the economy looked stronger in the period. With the
supply of inventories low and foreign demand robust, manufacturing activity
began to accelerate. The Institute for Supply Management's (ISM) survey of the
manufacturing sector, for instance, jumped 4.1 points between March and May. In
response, year-ahead forward rates on three-month deposits rose, and the yield
on the 10-year Treasury bond climbed lockstep. By early June, the rise in the
10-year Treasury bond yield eclipsed that of short-term rates, which triggered
a period of consolidation in the equity markets. Though the semiannual period
ended June 30, 2007 finished on a down-note, the gains returned during the full
period were still quite strong.

Returns in the equity market were broad; however, companies with mid to small
capitalizations outperformed large to mega capitalizations. In fact, shares of
growth-oriented small and mid cap companies led all other styles of investing.
The relative strength of small and mid caps reflected the large number of
private equity deals (reportedly worth more than $300 billion) announced
between January and June 2007. With the performance of large cap companies
trailing those of their smaller peers, the valuation gap (the difference
between the prices that investors are willing to pay for the earnings of the
companies in each index) widened. At the close of June, the price-to-earnings
ratio (P/E) of the S&P 100(R) Index/(3)/ was about 25% less than the P/E of the
small and mid cap indexes. Finally, unlike in the small and mid cap categories,
value continued its dominance over growth in the large cap space.

PORTFOLIO REVIEW

For the six-month period ended June 30, 2007, the Portfolio outperformed the
Russell Midcap(R) Index/(4)/. The Portfolio's underweight within the financial
services sector was the largest contributor to performance during the period as
this sector was negatively impacted by the fallout from a troubled sub-prime
mortgage market. The largest contributor to performance overall was Mosaic, the
world's largest phosphate producer, which benefited from higher demand and
improved pricing for fertilizer. The company also prepaid a portion of its
outstanding loans in an effort to reduce overall debt and improve the strength
of its balance sheet. King Pharmaceuticals, a healthcare holding, was another
significant performer. The company's stock price rose as it surprised the
Street by announcing higher than expected earnings for the fourth quarter of
2006, and again for the first quarter of 2007.

The largest detractor from performance was stock selection within the consumer
discretionary sector. Shares of OfficeMax fell after the company announced
disappointing first quarter results, driven mainly by profit deterioration in
its contract segment. Another significant detractor was JDS Uniphase, a
communications equipment supplier. Shares fell sharply after the company
announced a loss for the fiscal third quarter and lower guidance for the fourth
quarter. Another significant detractor during the first half of 2007 was
NiSource, an energy holding company. Shares slid after management announced
that it would not be pursuing the sale of its electric business as many
analysts had hoped it would.

OUTLOOK

Returns in the stock market have been strong for the past four years,
particularly in mid cap stocks. Valuations have compressed across the
capitalization spectrum, but they do not appear to be stretched. Profitability
at many companies is at peak levels and we are clearly in the later stages of
expansion. The recent financial turmoil and housing market pressure may slow
economic growth and perhaps impinge profitability going forward.

We will continue to invest in areas where we see company and industry catalysts
to improve below-average levels of profitability. We maintain our overweight
position in telecommunications, believing the companies will benefit from
reduced costs and expanded services, including television and high speed
internet. Telecommunications equipment suppliers also remain an area of focus
for us, as we expect them to improve profitability as telephone companies and
cable companies extend their networks. Recently we have increased our exposure
to more traditionally defensive companies by adding names within the consumer
staples and health care sectors.

We have maintained an underweight position in financial services for a number
of years. With the exception of insurance-related holdings, we have not seen
the combination of valuation and the potential for improving profitability that
would make the companies attractive to us. As a result, we have no exposure to
banks or sub-prime mortgage lenders, and have a significant relative
underweight position in REIT securities. However, the sub-prime mortgage
implosion, a growing fear of credit deterioration, and general uncertainty over
the direction of future fed policy may create the opportunity for future
investment.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B shares
because of the difference in expenses paid by policyholders investing in the
different share class.

/1/The S&P MidCap(R) 400/Citigroup Value Index consists of 400 domestic stocks
chosen for market size, liquidity, and industry group representation. The
blended Index is constructed by selecting the stocks in each index with high
book-to-price ratios. The Indices do not include fees or expenses and are not
available for direct investment.

/2/The Russell Midcap(R) Index is an unmanaged index which measures the
performance of the 800 smallest companies in the Russell 1000(R) Index, which
represent approximately 30% of the total market capitalization of the Russell
1000 Index. As of the latest reconstitution, the average market capitalization
was approximately $6.3 billion; the median market capitalization was
approximately $4.7 billion. The largest company in the Index had a market
capitalization of $18.3 billion. The Index does not include fees or expenses
and is not available for direct investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of the Class A shares is 8/20/97. Inception of the Class B shares
is 4/3/01. The Russell Midcap(R) Index returns are based on an inception date
of 8/20/97. The S&P MidCap(R) 400/Citigroup Value Index returns are based on an
inception date of 8/1/97.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Lord Abbett Mid-Cap Value Portfolio, which
is diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

8. ACQUISITIONS

On April 30, 2007, Lord Abbett Mid-Cap Value Portfolio ("Mid-Cap") acquired 73%
of the net assets of Lord Abbett America's Value Portfolio ("America"), a
series of Met Investors Series Trust, pursuant to a plan of reorganization
approved by America shareholders on April 24, 2007. The acquisition was
accomplished by a taxable exchange of 3,426,929 Class B shares of Mid-Cap
(valued at $267.8 Million) in exchange for the 4,787,094 Class B shares of
America outstanding on April 27, 2007. The aggregate Class B net assets of
Mid-Cap and America immediately before the acquisition were $267,841,421 and
$73,473,358, respectively. The aggregate Class B net assets of Mid-Cap
immediately after the acquisition were $341,314,779.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

ECONOMIC OVERVIEW & OUTLOOK

Equity markets rebounded strongly during the second quarter, following the
tumultuous months of February and March when the Shanghai stock market plunged
and subprime mortgage lending practices were brought to light. Despite concerns
over a slowing economy, rising energy prices and fallout from the subprime
market, the major market indexes performed surprisingly well during the period,
boosted by global economic growth and stronger than expected corporate earnings.

Mid caps, as measured by the Russell Midcap(R) Index, outperformed large and
small caps, as measured by the Russell Top 200(R) Index and the Russell 2000(R)
Index, respectively./1/ In terms of investment style, growth stocks,
represented by the Russell 3000(R) Growth Index, outperformed value stocks,
represented by the Russell 3000(R) Value Index./1/ Energy and materials were
the best performing sectors of the stock market, as measured by the S&P 500(R)
Index, while financials and consumer discretionary were the weakest performing
sectors during the period./1/

PORTFOLIO OVERVIEW

For the six months ended June 30, 2007, the Met/AIM Capital Appreciation
Portfolio had positive returns and outperformed the S&P 500(R) Index and the
Russell 1000(R) Growth Index on a net basis.

The Portfolio outperformed the Russell 1000(R) Growth Index by the widest
margin in the industrials sector. Within this sector, the Portfolio benefited
from solid stock selection in several industries, including aerospace and
defense and industrial conglomerates. An overweight position in electrical
equipment stocks also contributed to outperformance within the sector.

The Portfolio also benefited from outperformance in several other sectors,
including energy, telecom, consumer discretionary and healthcare.

Some of this positive outperformance was offset by underperformance in the
financials, materials and utilities sectors. In the financials sector,
underperformance was driven primarily by stock selection and an overweight
position in capital markets stocks. In the materials sector, underperformance
was driven by stock selection in the chemicals industry. Finally, in the
utilities sector, the underperformance was driven by an underweight position as
utility stocks continued to perform well.

During the period, exposure was added to the consumer discretionary,
industrials and consumer staples sectors, and decreased in the information
technology, materials and financials sectors.

These Portfolio changes resulted in a positioning that is expected to benefit
from moderate global economic growth, while maintaining significant exposure to
defensive growth stocks as the economic cycle shows signs of maturing. At the
close of the period, the portfolio was overweight in the industrials,
financials, consumer discretionary, and telecom sectors, and marketweight in
the health care and information technology sectors. Underweight positions
include the consumer staples, utilities, materials and energy sectors.

+The chart reflects the performance of Class A shares of the Portfolio.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-value weighted index (stock prices times number of shares outstanding),
with each stock's weight in the Index proportionate to its market value. The
Index does not include fees and expenses and is not available for direct
investment.

/2/The Russell 1000(R) Growth Index is an unmanaged index which measures the
performance of those Russell 1000 companies with higher price-to-book ratios
and higher forcasted growth values. The Index does not include fees or expenses
and is not available for direct investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gains distributions.

/4/Inception date of Class A shares is 10/10/1995. Inception date of Class E
shares is 4/28/2007. Index returns are based on an inception date of 10/10/1995.

/5/"Cumulative Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Met/AIM Capital Appreciation Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and E Shares are
offered by the Portfolio. Class B Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

On May 24, 2006, the Board of Trustees of the Trust approved the change of the
fiscal year end from October 31st to December 31 for the Portfolio. The
Portfolio's change of the fiscal year end was effective on November 1, 2006.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                    Expiring   Expiring    Expiring

Met/AIM Capital Appreciation Portfolio $39,623,952 $2,432,996 $25,303,918 $11,887,038


On May 1, 2006, the TST Portfolio was reorganized into the Portfolio, a series
of Met Investors Series Trust. The Portfolio acquired capital losses of
$51,774,317. The losses incurred by the Portfolio are subject to an annual
limitation of $10,410,524.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

Portfolio enters into a repurchase agreement, the value of the collateral
securities including accrued interest will be equal to or exceed the value of
the repurchase agreement and, for repurchase agreements that mature in more
than one day, the seller will agree that the value of the collateral securities
including accrued interest will continue to be at least equal to the value of
the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

ECONOMIC OVERVIEW & OUTLOOK

Equity markets rebounded strongly during the second quarter, following the
tumultuous months of February and March when the Shanghai stock market plunged
and subprime mortgage lending practices were brought to light. Despite concerns
over a slowing economy, rising energy prices and fallout from the subprime
market, the major market indexes performed surprisingly well during the period,
boosted by global economic growth and stronger than expected corporate earnings.

Mid caps, as measured by the Russell Midcap(R) Index, outperformed large and
small caps, as measured by the Russell Top 200(R) Index and the Russell 2000
Index, respectively./1/ In terms of investment style, growth stocks,
represented by the Russell 3000(R) Growth Index, outperformed value stocks,
represented by the Russell 3000(R) Value Index./1/ Energy and materials were
the best performing sectors of the stock market, as measured by the S&P 500(R)
Index, while financials and consumer discretionary were the weakest performing
sectors during the period./1/

PORTFOLIO OVERVIEW

For the six months ended June 30, 2007, the Met/AIM Small Cap Growth Portfolio
had positive returns and outperformed both the Russell 2000(R) Index and the
Russell 2000(R) Growth Index on a net basis.

The Portfolio outperformed the Russell 2000(R) Growth Index benchmark index by
the widest margin in the information technology sector. Within this sector, the
Portfolio benefited from solid stock selection in several industries, including
internet software/services and software.

The Portfolio also benefited from outperformance in several other sectors,
including financials, industrials, energy and healthcare.

The only sector in which the Portfolio underperformed versus the Russell
2000(R) Growth Index was the consumer discretionary sector. Within this sector,
underperformance was largely due to stock selection in the specialty retail,
diversified consumer services and media industries.

The Portfolio performed in-line with the Russell 2000(R) Growth Index in the
materials and utilities sectors.

During the period, exposure was added to the industrials, materials and
consumer staples sectors, and decreased in the energy, consumer discretionary
and information technology sectors.

These Portfolio changes resulted in a positioning that is expected to benefit
from moderate global economic growth, while maintaining significant exposure to
defensive growth stocks as the economic cycle shows signs of maturing. At the
close of the period, the portfolio was overweight in the information
technology, telecom and consumer staples sectors, and underweight in the
consumer discretionary sector versus the Russell 2000(R) Growth Index.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The Russell 2000(R) Index is an unmanaged index which measures the
performance of the 2,000 smallest companies in the Russell 3000(R) Index, which
represents approximately 8% of the total market capitalization of the Russell
3000(R) Index. As of the latest reconstitution, the average market
capitalization was approximately $898.3 million; the median market
capitalization was approximately $705.4 million. The largest company in the
index had a market capitalization of $2.5 billion. The Index does not include
fees or expenses and is not available for direct investment.

/2/The Russell 2000(R) Growth Index is an unmanaged index which measures the
performance of those Russell 2000 companies with higher price-to-book ratios
and higher forecasted growth values. The Index does not include fees or
expenses and is not available for direct investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of the Class A shares is 1/2/02. Inception of the Class B shares
is 10/9/01. Inception of the Class E shares is 4/01/02. Index returns are based
on an inception date of 10/9/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Met/AIM Small Cap Growth Portfolio, which
is diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. ACQUISITIONS

On May 1, 2006, Met/AIM Small Cap Growth Portfolio ("Met/AIM") acquired all of
the net assets of Style Focus Series: Small Cap Growth Portfolio, a series of
The Travelers Series Trust ("Style Focus"), pursuant to a plan of
reorganization approved by Style Focus shareholders on March 14, 2006. The
acquisition was accomplished by a tax-free exchange of 670,445 Class A shares
of Met/AIM (valued at $9.1 million) in exchange for the 715,654 Class A shares
of Style Focus outstanding on April 28, 2006. Style Focus Class A net assets at
that date ($9.1 million), including $1,296,475 of unrealized appreciation were
combined with those of Met/AIM Class A. The cost of securities acquired in the
tax-free exchange by Met/AIM from Style Focus was $7,888,935. The aggregate
Class A net assets of Met/AIM and Style Focus immediately before the
acquisition were $271,272,413 and $9,138,167, respectively. The aggregate Class
A net assets of Met/AIM immediately after the acquisition were $280,410,580.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MANAGED BY MET INVESTORS ADVISORY, LLC

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------

For the six months ended June 30, 2007, the MetLife Aggressive Strategy
Portfolio gained 6.98%. This compares to a 7.56% return for the Dow Jones
Wilshire 5000 Index and a 7.97% return for the blended benchmark (the
Aggressive Blended Benchmark is comprised of the following mix: 76% Wilshire
5000, 19% MSCI EAFE(R) Index, and 5% CG 90-Day T-Bill).

The U.S. equity markets continued the positive momentum from the beginning of
the year as strong gains culminated in early June with records highs for the
Dow and S&P 500 Indexes. The primary driver of the rally was strong corporate
profits resulting from strong overseas demand and a weaker dollar. Stock
markets moved higher both in the U.S. and abroad despite signs of a slowing
economy in the U.S. and ongoing concerns about inflation. Other concerns also
included credit-related problems such as the ongoing subprime lending issue and
some high-profile losses in the hedge fund industry. Despite the concerns
mentioned above investors pointed towards strong economic growth outside the
U.S. and a boom in merger activity (a 90% increase over the second quarter of
2006) as positive signs for the global economy overall. The bond market
experienced rising yields as investors sought slightly higher premiums on high
yield and mortgage related debt securities. The Federal Reserve stayed on hold,
indicating a reluctance to cut U.S. rates due to concerns about inflation.

During the period strong performance in the small and mid cap sectors due to
favorable market conditions contributed to performance specifically the Met/AIM
Small Cap Growth Portfolio and the Turner Mid-Cap Growth Portfolio. Another
notable positive was our position in the Third Avenue Small Cap Value Portfolio
whose out-performance was driven by appreciation from various holdings within
the oil, gas and energy sectors.

Also contributing to overall performance were the Davis Venture Value and the
Van Kampen Comstock Portfolios. Stock selection within the financials sector
and a modest overweight to the energy sector drove performance for the Davis
Venture Value Portfolio while stock picks within the technology sector
increased returns for the Van Kampen Comstock Portfolio. On the international
side, the MFS Research International Portfolio added to performance due to
continued strength in foreign markets. The MFS(R) Emerging Markets Equity
Portfolio also contributed to absolute returns as emerging-markets stocks
continued to rally.

Equity performance was adversely impacted by exposure to the healthcare sector
for the Legg Mason Partners Aggressive Growth Portfolio. A general
underweighting in energy stocks hurt performance for the Legg Mason Value
Equity Portfolio and the Lord Abbett Growth and Income Portfolio. Finally, the
Jennison Growth Portfolio's stock selection in the consumer discretionary
sector detracted from performance. On the fixed income side, the PIMCO Total
Return Portfolio was also a detractor due to above-index duration as interest
rates rose over the period.

A correction in the real estate securities market occurred after a significant
period of out-performance. The Neuberger Berman Real Estate Portfolio, as a
result, was the largest detractor from absolute performance during the period.
The allocation to real estate has provided significant returns over the past
few years and the asset class continues to offer diversification benefits for
the Portfolio.

The Portfolio allocations were adjusted in early May 2007. Specifically, we
added real estate exposure for greater diversification and rebalanced the
growth and value sectors of the large cap equity component of the Portfolio.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The Wilshire 5000 Equity Index is an unmanaged index which measures the
performance of all U.S. headquartered equity securities with readily available
price data. The market capitalized weighted index is compromised of
approximately 82% New York Stock Exchange, 2% American Stock Exchange and 16%
OTC (1995). The Index was created in 1974 and backdated to 1971, with a base
index of December 1980 (base index equals 1,044.596). Dividends are reinvested
on the "ex" dividend date and the rebalancing of share weights is done on a
monthly basis. No attempt has been made to adjust the market capitalization of
the index to take into account cross holding between corporations. The Index
does not include fees or expenses and is not available for direct investment.

/2/The Aggressive Blended Benchmark is comprised of 76% Wilshire 5000 Equity
Index, 19% Morgan Stanley Capital International Europe Australasia and Far East
Index ("MSCI EAFE(R) Index") and 5% Citigroup 3-Month Treasury Bill Index.

The MSCI EAFE(R) Index is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance, excluding the US & Canada. The Index does not include fees or
expenses and is not available for direct investment.

The Citigroup 3-Month Treasury Bill Index--equal dollar amounts of three-month
Treasury bills are purchased at the beginning of each of three consecutive
months. As each bill matures, all proceeds are rolled over or reinvested in a
new three-month bill. The income used to calculate the monthly return is
derived by subtracting the original amount invested from the maturity value.
The Index does not include fees or expenses and is not available for direct
investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of the Class B shares is 11/4/04. Inception of the Class A shares
is 5/2/05. Index returns are based on an inception date of 10/31/04.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

account value over the period, multiplied by 181/365 (to reflect the one-half
year period).

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is MetLife Aggressive Strategy Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary

Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into a management
agreement for investment advisory services in connection with the investment
management of the Portfolio.

Under the terms of the Portfolio's management agreement, the Portfolio pays the

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

7. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

8. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MANAGED BY MET INVESTORS ADVISORY, LLC

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


For the six months ended June 30, 2007, the MetLife Balanced Strategy Portfolio
gained 5.83%. This compares to a 6.53% return of the MSCI Global Capital
Markets Index and a 5.82% return for the blended benchmark (the Balanced
Blended Benchmark is comprised of the following mix: 52% Wilshire 5000, 30%
Lehman Brothers Universal, 13% MSCI EAFE(R) Index, and 5% CG 90-Day T-Bill).

The U.S. equity markets continued the positive momentum from the beginning of
the year as strong gains culminated in early June with records highs for the
Dow and S&P 500(R) Indexes. The primary driver of the rally was strong
corporate profits resulting from strong overseas demand and a weaker dollar.
Stock markets moved higher both in the U.S. and abroad despite signs of a
slowing economy in the U.S. and ongoing concerns about inflation. Other
concerns also included credit-related problems such as the ongoing subprime
lending issue and some high-profile losses in the hedge fund industry. Despite
the concerns mentioned above investors pointed towards strong economic growth
outside the U.S. and a boom in merger activity (a 90% increase over the second
quarter of 2006) as positive signs for the global economy overall. The bond
market experienced rising yields as investors sought slightly higher premiums
on high yield and mortgage related debt securities. The Federal Reserve stayed
on hold, indicating a reluctance to cut U.S. rates due to concerns about
inflation.

On the equity side, strong performance in the small and mid cap sectors due to
favorable market conditions contributed to performance specifically the T. Rowe
Price Mid-Cap Growth Portfolio and the Lazard Mid-Cap Portfolio. Another
notable positive was our position in the Third Avenue Small Cap Value Portfolio
whose out-performance was driven by appreciation from various holdings within
the oil, gas and energy sectors.

Also contributing to overall performance were the Davis Venture Value and the
Van Kampen Comstock Portfolios. Stock selection within the financials sector
and a modest overweight to the energy sector drove performance for the Davis
Venture Value Portfolio while stock picks within the technology sector
increased returns for the Van Kampen Comstock Portfolio. On the international
side, the MFS Research International Portfolio added to performance due to
continued strength in foreign markets.

During the period our portfolio allocations to the international debt,
convertibles and high yield sectors of the bond market were moderate
contributors to performance. The Loomis Sayles Global Markets Portfolio and the
Lord Abbett Bond Debenture Portfolio, both of which combine fixed income and
equity, or equity-like, securities, were contributors to returns.

Equity performance was adversely impacted by exposure to the healthcare sector
for the Legg Mason Partners Aggressive Growth Portfolio. A general
underweighting in energy stocks hurt performance for the Legg Mason Value
Equity Portfolio and the Lord Abbett Growth and Income Portfolio. Finally, the
Jennison Growth Portfolio's stock selection in the consumer discretionary
sector detracted from performance.

The Western Asset Management U.S. Government Portfolio detracted from
performance due to slightly longer duration relative to the benchmark as well
as structural exposure to agency mortgages. The PIMCO Total Return Portfolio
was also a detractor due to above-index duration as interest rates rose over
the period.

A correction in the real estate securities market occurred after a significant
period of out-performance. The Neuberger Berman Real Estate Portfolio, as a
result, was the largest detractor from absolute performance during the period.
The allocation to real estate has provided significant returns over the past
few years and the asset class continues to offer diversification benefits for
the Portfolio.

The Portfolio allocations were adjusted in early May 2007. Specifically, we
further diversified the fixed income component and rebalanced the growth and
value sectors of the large cap equity component of the Portfolio.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

long-term indices composed of bonds with maturities longer than ten years. All
returns are market value weighted inclusive of accrued interest. Yield is
defined as the yield to worst, the lesser of the yield to maturity and yield to
call. Market Values are expressed in millions of dollars. The Index does not
include fees or expenses and is not available for direct investment.

The Morgan Stanley Capital International Europe, Australasia and Far East Index
("MSCI EAFE(R) Index") is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance, excluding the US & Canada. The Index does not include fees or
expenses and is not available for direct investment.

The Citigroup 3-Month Treasury Bill Index--equal dollar amounts of three-month
Treasury bills are purchased at the beginning of each of three consecutive
months. As each bill matures, all proceeds are rolled over or reinvested in a
new three-month bill. The income used to calculate the monthly return is
derived by subtracting the original amount invested from the maturity value.
The Index does not include fees or expenses and is not available for direct
investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of the Class B shares is 11/4/04. Inception of the Class A shares
is 5/2/05. Index returns are based on an inception date of 10/31/04.

Effective July 1, 2007, Morgan Stanley Capital International, Inc. (MSCI)
discontinued the MSCI Global Capital Markets Index and the Portfolio will use
the Dow Jones Moderate Portfolio Index in future reports to policyholders as
the Portfolio's primary benchmark.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is MetLife Balanced Strategy Portfolio, which
is non-diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into a management
agreement for investment advisory services in connection with the investment
management of the Portfolio.

Under the terms of the Portfolio's management agreement, the Portfolio pays the
Manager a monthly fee based upon annual rates applied to the Portfolio's
average daily net assets as follows:

("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

7. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

8. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

9. OTHER MATTERS

The Portfolio does not invest in the Underlying Portfolios for the purpose of
exercising management or control; however, investments by the Portfolio within
its principal investment strategies may represent a significant portion of the
Underlying Portfolio's net assets. Transactions in the Underlying Portfolios
during the period during the period ended June 30, 2007 in which the Portfolio

METLIFE DEFENSIVE STRATEGY PORTFOLIO               FOR THE PERIOD ENDED 6/30/07
MANAGED BY MET INVESTORS ADVISORY, LLC

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


For the six months ended June 30, 2007, the MetLife Defensive Strategy
Portfolio gained 3.66%. This compares to a 6.53% return for the MSCI Global
Capital Markets Index and a 3.75% return for the blended benchmark (the blended
benchmark for this Portfolio is comprised of the following mix: 28% Wilshire
5000 Index, 55% Lehman Brothers Universal Index, 7% MSCI EAFE Index, and 10% CG
90-Day T-Bill Index).

The U.S. equity markets continued the positive momentum from the beginning of
the year as strong gains culminated in early June with records highs for the
Dow and S&P 500 Indexes. The primary driver of the rally was strong corporate
profits resulting from strong overseas demand and a weaker dollar. Stock
markets moved higher both in the U.S. and abroad despite signs of a slowing
economy in the U.S. and ongoing concerns about inflation. Other concerns also
included credit-related problems such as the ongoing subprime lending issue and
some high-profile losses in the hedge fund industry. Despite the concerns
mentioned above investors pointed towards strong economic growth outside the
U.S. and a boom in merger activity (a 90% increase over the second quarter of
2006) as positive signs for the global economy overall. The bond market
experienced rising yields as investors sought slightly higher premiums on high
yield and mortgage related debt securities. The Federal Reserve stayed on hold,
indicating a reluctance to cut U.S. rates due to concerns about inflation.

During the period our portfolio allocations to the Treasury Inflation Protected
Securities, international debt, convertibles and high yield sectors of the bond
market were positive contributors to performance. The Loomis Sayles Global
Markets Portfolio and the Lord Abbett Bond Debenture Portfolios, both of which
combine fixed income and equity, or equity-like, securities, were two of the
larger contributors to returns.

On the equity side, strong performance in the small and mid cap sectors due to
favorable market conditions contributed to performance specifically the T. Rowe
Price Mid-Cap Growth Portfolio and the Lazard Mid-Cap Portfolio. Another
notable positive was our position in the Third Avenue Small Cap Value Portfolio
whose out-performance was driven by appreciation from various holdings within
the oil, gas and energy sectors. Also adding to overall performance was the
MFS(R) Research International Portfolio due to continued strength in foreign
markets.

The Western Asset Management U.S. Government Portfolio detracted from
performance due to slightly longer duration relative to the benchmark as well
as structural exposure to agency mortgages. The PIMCO Total Return Portfolio
was also a detractor due to above-index duration as interest rates rose over
the period.

Equity performance was adversely impacted by a general underweighting in energy
stocks for the Legg Mason Value Equity Portfolio and the Lord Abbett Growth and
Income Portfolio. Finally, the Jennison Growth Portfolio's stock selection in
the consumer discretionary sector detracted from performance.

A correction in the real estate securities market occurred after a significant
period of out-performance. The Neuberger Berman Real Estate Portfolio, as a
result, was the largest detractor from absolute performance during the period.
The allocation to real estate has provided significant returns over the past
few years and the asset class continues to offer diversification benefits for
the Portfolio.

The Portfolio allocations were adjusted in early May 2007. Specifically, we
further diversified the fixed income component and rebalanced the growth and
value sectors of the large cap equity component of the Portfolio.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The MSCI Global Capital Markets Index/SM/ an unmanaged index which measure
the performance of the core capital markets asset classes comprising global
equities and fixed income. It is a market capitalization weighted composite of
the MSCI All Country World Index/SM/ and the MSCI Global Total Bond Index/SM/.
The MSCI All Country World Index/SM/ is an unmanaged free float-adjusted market
capitalization index that is designed to measure equity market performance in
the global developed and emerging markets. The MSCI All Country World Index
includes 49 country indices. The MSCI Global Total Bond Index an unmanaged
index which measures the capitalization weighted performance of sovereign,
investment grade credit and high yield bond markets with appropriate

Total Bond Index/SM/ includes the World Sovereign Debt Index, USD Total Bond
Index, Euro Dollar Credit Index, Euro Sterling Credit Index, Euro Credit Index,
Emerging Market Local Sovereign Index and High Yield Sovereign and Corporate
Indices. The Index does not include fees or expenses and is not available for

/2/The Defensive Blended Benchmark is comprised of 28% Wilshire 5000 Equity
Index, 55% Lehman Brothers Universal Index, 7% Morgan Stanley Capital
International Europe Australasia and Far East Index and 10% Citigroup 3-Month
Treasury Bill Index.

The Wilshire 5000 Equity Index is an unmanaged index which measures the
performance of all U.S. headquartered equity securities with readily available
price data. The market capitalized weighted index is compromised of
approximately 82% New York Stock Exchange, 2% American Stock Exchange and 16%
OTC (1995). The Index was created in 1974 and backdated to 1971; with a base
index of December 1980 (base index equals 1,044.596). Dividends are reinvested
on the "ex" dividend date and the rebalancing of share weights is done on a
monthly basis. No attempt has been made to adjust the market capitalization of
the Index to take into account cross holding between corporations. The Index
does not include fees or expenses and is not available for direct investment.

The Lehman Brothers Universal Index represents the union of the U.S. Aggregate
Index, the U.S. High-Yield Corporate Index, the 144A Index, the Eurodollar
Index, the Emerging Markets Index, the non-EIRSA portion of the Commercial

long-term indices composed of bonds with maturities longer than ten years. All
returns are market value weighted inclusive of accrued interest. Yield is
defined as the yield to worst, the lesser of the yield to maturity and yield to
call. Market values are expressed in millions of dollars. The Index does not
include fees or expenses and is not available for direct investment.

The Morgan Stanley Capital International Europe, Australasia and Far East Index
("MSCI EAFE(R) Index") is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance, excluding the US & Canada. The Index does not include fees or
expenses and is not available for direct investment.

The Citigroup 3-Month Treasury Bill Index--equal dollar amounts of three-month
Treasury bills are purchased at the beginning of each of three consecutive
months. As each bill matures, all proceeds are rolled over or reinvested in a
new three-month bill. The income used to calculate the monthly return is
derived by subtracting the original amount invested from the maturity value.
The Index does not include fees or expenses and is not available for direct
investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of the Class B shares is 11/4/04. Inception of the Class A shares
is 5/2/05. Index returns are based on an inception date of 10/31/04.

Effective July 1, 2007, Morgan Stanley Capital International, Inc. (MSCI)
discontinued the MSCI Global Capital Markets Index and the Portfolio will use
the Dow Jones Moderately Conservative Portfolio Index in future reports to
policyholders as the Portfolio's primary benchmark.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is MetLife Defensive Strategy Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary

administration of the Trust. The Manager has entered into a management
agreement for investment advisory services in connection with the investment
management of the Portfolio.

("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

7. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

8. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

9. OTHER MATTERS

MANAGED BY MET INVESTORS ADVISORY, LLC

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------

The MetLife Growth Strategy Portfolio performance for the six months ended
June 30, 2007 was a gain of 6.82%. This compares to a 6.53% return for the MSCI
Global Capital Markets Index and a 7.26% return for the blended benchmark (the
Growth Blended Benchmark is comprised of the following mix: 68% Wilshire 5000,
10% Lehman Brothers Universal, 17% MSCI EAFE, and 5% CG 90-Day T-Bill).

The U.S. equity markets continued the positive momentum from the beginning of
the year as strong gains culminated in early June with records highs for the
Dow and S&P 500 Indexes. The primary driver of the rally was strong corporate
profits resulting from strong overseas demand and a weaker dollar. Stock
markets moved higher both in the U.S. and abroad despite signs of a slowing
economy in the U.S. and ongoing concerns about inflation. Other concerns also
included credit-related problems such as the ongoing subprime lending issue and
some high-profile losses in the hedge fund industry. Despite the concerns
mentioned above investors pointed towards strong economic growth outside the
U.S. and a boom in merger activity (a 90% increase over the second quarter of
2006) as positive signs for the global economy overall. The bond market
experienced rising yields as investors sought slightly higher premiums on high
yield and mortgage related debt securities. The Federal Reserve stayed on hold,
indicating a reluctance to cut U.S. rates due to concerns about inflation.

During the period strong performance in the small and mid cap sectors due to
favorable market conditions contributed to performance specifically the Met/AIM
Small Cap Growth Portfolio and the T. Rowe Price Mid-Cap Growth Portfolio.
Another notable positive was our position in the Third Avenue Small Cap Value
Portfolio whose out-performance was driven by appreciation from various
holdings within the oil, gas and energy sectors.

Also contributing to overall performance were the Davis Venture Value and the
Van Kampen Comstock Portfolios. Stock selection within the financials sector
and a modest overweight to the energy sector drove performance for the Davis
Venture Value Portfolio while stock picks within the technology sector
increased returns for the Van Kampen Comstock Portfolio. On the international
side, the MFS Research International Portfolio added to performance due to
continued strength in foreign markets. The MFS(R) Emerging Markets Equity
Portfolio also contributed to absolute returns as emerging-markets stocks
continued to rally.

During the period our portfolio allocations to the international debt,
convertibles and high yield sectors of the bond market were moderate
contributors to performance. The Loomis Sayles Global Markets Portfolio which
combines fixed income and equity, or equity-like, securities, was a contributor
to returns.

Equity performance was adversely impacted by exposure to the healthcare sector
for the Legg Mason Partners Aggressive Growth Portfolio. A general
underweighting in energy stocks hurt performance for the Legg Mason Value
Equity Portfolio and the Lord Abbett Growth and Income Portfolio. Finally, the
Jennison Growth Portfolio's stock selection in the consumer discretionary
sector detracted from performance. On the fixed income side, the PIMCO Total
Return Portfolio was also a detractor due to above-index duration as interest
rates rose over the period.

A correction in the real estate securities market occurred after a significant
period of out-performance. The Neuberger Berman Real Estate Portfolio, as a
result, was the largest detractor from absolute performance during the period.
The allocation to real estate has provided significant returns over the past
few years and the asset class continues to offer diversification benefits for
the Portfolio.

The Portfolio allocations were adjusted in early May 2007. Specifically, we
further diversified the fixed income component and rebalanced the growth and
value sectors of the large cap equity component of the Portfolio.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The MSCI Global Capital Markets Index/SM/ is an unmanaged index which
measures the performance of the core capital markets asset classes comprising
global equities and fixed income. It is a market capitalization weighted
composite of the MSCI All Country World Index/SM/ and the MSCI Global Total
Bond Index/SM/. The MSCI All Country World Index/SM/ is an unmanaged free
float-adjusted market capitalization index which measure equity market
performance in the global developed and emerging markets. The MSCI All Country
World Index includes 49 country indices. The MSCI Global Total Bond Index is an

Total Bond Index includes the World Sovereign Debt Index, USD Total Bond Index,
Euro Dollar Credit Index, Euro Sterling Credit Index, Euro Credit Index,
Emerging Market Local Sovereign Index and High Yield Sovereign and Corporate
Indices. The Index does not include fees or expenses and is not available for

/2/The Growth Blended Benchmark is comprised of 68% Wilshire 5000 Equity Index,
10% Lehman Brothers Universal Index, 17% Morgan Stanley Capital International
Europe Australasia and Far East Index(the MSCI EAFE(R) Index) and 5% Citigroup
3-Month Treasury Bill Index.

The Wilshire 5000 Equity Index is an unmanaged index which measures the
performance of all U.S. headquartered equity securities with readily available
price data. The market capitalized weighted index is compromised of
approximately 82% New York Stock Exchange, 2% American Stock Exchange and 16%
OTC (1995). The Index was created in 1974 and backdated to 1971; with a base
index of December 1980 (base index equals 1,044.596). Dividends are reinvested
on the "ex" dividend date and the rebalancing of share weights is done on a
monthly basis. No attempt has been made to adjust the market capitalization of
the Index to take into account cross holding between corporations. The Index
does not include fees or expenses and is not available for direct investment.

The Lehman Brothers Universal Index represents the union of the U.S. Aggregate
Index, the U.S. High-Yield Corporate Index, the 144A Index, the Eurodollar
Index, the Emerging Markets Index, the non-EIRSA portion of the Commercial
Mortgage Backed Securities Index and the Commercial Mortgage Backed Securities
High Yield Index. Municipal debt, private placements, and non-dollar
denominated issues are excluded from the Universal Index. The only constituent
of the Index that includes floating-rate debt is the Emerging Markets Index.

returns are market value weighted inclusive of accrued interest. Yield is
defined as the yield to worst, the lesser of the yield to maturity and yield to
call. Market values are expressed in millions of dollars. The Index does not
include fees or expenses and is not available for direct investment.

The MSCI EAFE(R) Index is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance, excluding the US & Canada. The Index does not include fees or
expenses and is not available for direct investment.

The Citigroup 3-Month Treasury Bill Index--equal dollar amounts of three-month
Treasury bills are purchased at the beginning of each of three consecutive
months. As each bill matures, all proceeds are rolled over or reinvested in a
new three-month bill. The income used to calculate the monthly return is
derived by subtracting the original amount invested from the maturity value.
The Index does not include fees or expenses and is not available for direct
investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of the Class B shares is 11/4/04. Inception of the Class A shares
is 5/2/05. Index returns are based on an inception date of 10/31/04.

Effective July 1, 2007, Morgan Stanley Capital International, Inc. (MSCI)
discontinued the MSCI Global Capital Markets Index and the Portfolio will use
the Dow Jones Moderately Aggressive Portfolio Index in future reports to
policyholders as the Portfolio's primary benchmark.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is MetLife Growth Strategy Portfolio, which
is non-diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

7. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

8. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MANAGED BY MET INVESTORS ADVISORY, LLC

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


The MetLife Moderate Strategy Portfolio performance for the six months ended
June 30, 2007 was a gain of 4.94%. This compares to a 6.53% return for the MSCI
Global Capital Markets Index and a 4.75% return for the blended benchmark (the
Moderate Blended Benchmark is comprised of the following mix: 40% Wilshire
5000, 45% Lehman Brothers Universal, 10% MSCI EAFE(R) Index, and 5% CG 90-Day
T-Bill).

The U.S. equity markets continued the positive momentum from the beginning of
the year as strong gains culminated in early June with record highs for the Dow
and S&P 500(R) Indexes. The primary driver of the rally was strong corporate
profits resulting from strong overseas demand and a weaker dollar. Stock
markets moved higher both in the U.S. and abroad despite signs of a slowing
economy in the U.S. and ongoing concerns about inflation. Other concerns also
included credit-related problems such as the ongoing subprime lending issue and
some high-profile losses in the hedge fund industry. Despite the concerns
mentioned above investors pointed towards strong economic growth outside the
U.S. and a boom in merger activity (a 90% increase over the second quarter of
2006) as positive signs for the global economy overall. The bond market
experienced rising yields as investors sought slightly higher premiums on high
yield and mortgage related debt securities. The Federal Reserve stayed on hold,
indicating a reluctance to cut U.S. rates due to concerns about inflation.

During the period our portfolio allocations to the Treasury Inflation Protected
Securities, international debt, convertibles and high yield sectors of the bond
market were contributors to performance. The Loomis Sayles Global Markets
Portfolio and the Lord Abbett Bond Debenture Portfolio, both of which combine
fixed income and equity, or equity-like, securities, were two of the larger
contributors to returns.

On the equity side, strong performance in the small and mid cap sectors due to
favorable market conditions contributed to performance specifically the T. Rowe
Price Mid-Cap Growth Portfolio and the Lazard Mid-Cap Portfolio. Another
notable positive was our position in the Third Avenue Small Cap Value Portfolio
whose out-performance was driven by appreciation from various holdings within
the oil, gas and energy sectors.

Also contributing to overall performance was the Davis Venture Value Portfolio
as stock selection within the financials sector and a modest overweight to the
energy sector drove performance. On the international side, the MFS(R) Research
International Portfolio added to performance due to continued strength in
foreign markets.

The Western Asset Management U.S. Government Portfolio detracted from
performance due to slightly longer duration relative to the benchmark as well
as structural exposure to agency mortgages. The PIMCO Total Return Portfolio
was also a detractor due to above-index duration as interest rates rose over
the period.

Equity performance was adversely impacted by a general underweighting in energy
stocks for the Legg Mason Value Equity Portfolio and the Lord Abbett Growth and
Income Portfolio. Finally, the Jennison Growth Portfolio's stock selection in
the consumer discretionary sector detracted from performance.

A correction in the real estate securities market occurred after a significant
period of out-performance. The Neuberger Berman Real Estate Portfolio, as a
result, was the largest detractor from absolute performance during the period.
The allocation to real estate has provided significant returns over the past
few years and the asset class continues to offer diversification benefits for
the Portfolio.

The Portfolio allocations were adjusted in early May 2007. Specifically, we
further diversified the fixed income component and rebalanced the growth and
value sectors of the large cap equity component of the Portfolio.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The MSCI Global Capital Markets Index/SM/ is an unmanaged index which
measures the performance of the core capital markets asset classes comprising
global equities and fixed income. It is a market capitalization weighted
composite of the MSCI All Country World Index/SM/ and the MSCI Global Total
Bond Index/SM/. The MSCI All Country World Index/SM/ is an unmanaged free
float-adjusted market capitalization index which measure equity market
performance in the global developed and emerging markets. The MSCI All Country
World Index includes 49 country indices. The MSCI Global Total Bond Index is an
unmanaged index which measures the capitalization weighted performance of
sovereign, investment grade credit and high yield bond markets with appropriate
adjustments for investability and to eliminate double counting. The MSCI Global
Total Bond Index includes the World Sovereign Debt Index, USD Total Bond Index,
Euro Dollar Credit Index, Euro Sterling Credit Index, Euro Credit Index,
Emerging Market Local Sovereign Index and High Yield Sovereign and Corporate
Indices. The Index does not include fees or expenses and is not available for
direct investment.

/2/The Moderate Blended Benchmark is comprised of 40% Wilshire 5000 Equity
Index, 45% Lehman Brothers Universal Index, 10% Morgan Stanley Capital
International Europe Australasia and Far East Index (the MSCI EAFE(R) Index)
and 5% Citigroup 3-Month Treasury Bill Index.

The Wilshire 5000 Equity Index is an unmanaged index which measures the
performance of all U.S. headquartered equity securities with readily available
price data. The market capitalized weighted index is compromised of
approximately 82% New York Stock Exchange, 2% American Stock Exchange and 16%
OTC (1995). The Index was created in 1974 and backdated to 1971; with a base
index of December 1980 (base index equals 1,044.596). Dividends are reinvested
on the "ex" dividend date and the rebalancing of share weights is done on a
monthly basis. No attempt has been made to adjust the market capitalization of
the Index to take into account cross holding between corporations. The Index
does not include fees or expenses and is not available for direct investment.

The Lehman Brothers Universal Index represents the union of the U.S. Aggregate
Index, the U.S. High-Yield Corporate Index, the 144A Index, the Eurodollar
Index, the Emerging Markets Index, the non-EIRSA portion of the Commercial
Mortgage Backed Securities Index and the Commercial Mortgage Backed Securities
High Yield Index. Municipal debt, private placements, and non-dollar

long-term indices composed of bonds with maturities longer than ten years. All
returns are market value weighted inclusive of accrued interest. Yield is
defined as the yield to worst, the lesser of the yield to maturity and yield to
call. Market values are expressed in millions of dollars. The Index does not
include fees or expenses and is not available for direct investment.

The MSCI EAFE(R) Index is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance, excluding the US & Canada. The Index does not include fees or
expenses and is not available for direct investment.

The Citigroup 3-Month Treasury Bill Index--equal dollar amounts of three-month
Treasury bills are purchased at the beginning of each of three consecutive
months. As each bill matures, all proceeds are rolled over or reinvested in a
new three-month bill. The income used to calculate the monthly return is
derived by subtracting the original amount invested from the maturity value.
The Index does not include fees or expenses and is not available for direct
investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of the Class B shares is 11/4/04. Inception of the Class A shares
is 5/2/05. Index returns are based on an inception date of 10/31/04.

Effective July 1, 2007, Morgan Stanley Capital International, Inc. (MSCI)
discontinued the MSCI Global Capital Markets Index and the Portfolio will use
the Dow Jones Moderate Portfolio Index in future reports to policyholders as
the Portfolio's primary benchmark.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is MetLife Moderate Strategy Portfolio, which
is non-diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

7. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

8. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

SUMMARY OF RESULTS

For the six months ended June 30, 2007, the MFS(R) Emerging Markets Equity
Portfolio provided a total return of 14.74% for Class A. This compares with a
return of 17.75% for the Portfolio's benchmark, the MSCI Emerging Markets
Index/SM/.

DETRACTORS FROM PERFORMANCE

The portfolio's underweighted position in the industrial goods and services
sector detracted from relative performance. Not holding ship-building firm
Hyundai Heavy (South Korea), whose stock price more than doubled over the
reporting period, hurt relative results.

Security selection in the utilities and communications sector also dampened
relative returns. Not holding strong-performing wireless communications company
America Movil (Mexico) weighed on performance.

The combination of an overweighted position and security selection in the
health care sector had a negative impact on results. The portfolio's
positioning in pharmaceutical firm Gedeon Richter/(g)/ (Hungary) and generic
drug manufacturer Teva Pharmaceutical (Israel) hurt performance as both stocks
lagged the benchmark.

Stocks in other sectors that hurt results included microchip and electronics
manufacturer Samsung Electronics (South Korea), global software services firm
HCL Technologies/(aa)/ (India), and banking and financial services firm Nossa
Caixa-Nosso Banco/(g) /(Brazil).

The Portfolio's cash position detracted from relative performance. The
Portfolio holds some cash to buy new holdings and to provide liquidity. In a
period when equity markets increased, as measured by the portfolio's benchmark,
holding cash hurts performance versus the benchmark, which has no cash position.

CONTRIBUTORS TO PERFORMANCE

Security selection and an overweighted position in the basic materials sector
boosted relative performance. Iron ore producer Companhia Vale do Rio Doce
(Brazil), mining companies Grupo Mexico SAB De CV (Mexico) and Southern
Copper/(aa)/ (U.S.), and industrial conglomerate LG Group (South Korea) were
among the portfolio's top contributors. Underweighting steel products and
electronics manufacturer Posco/(g)/ (South Korea) also helped.

Stocks in other sectors that contributed to performance included brewing
company Companhia de Bebidas das Americas (Brazil) and petrochemical firm
Reliance Industries (India). Underweighting technology consulting firm Infosys/
(g)/ (India) and avoiding poor-performing gas and oil exploration firm
Surgutneftegaz/(g) /(Russia) also helped.

/(aa)/ Security is not a benchmark constituent.

/(g)/ Security was not held in the portfolio at period end.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B shares
because of the difference in expenses paid by policyholders investing in the
different share class.

/1/The Morgan Stanley Capital International (MSCI) Emerging Market Free (EMF)
Index/SM/ is an unmanaged market capitalization weighted equity index composed
of companies that are representative of the market structure of the following
26 countries: Argentina, Brazil, Chile, China, Colombia, Czech Republic, Egypt,
Hungary, India, Indonesia, Israel, Jordan, Korea, Malaysia, Mexico, Morocco,
Pakistan, Peru, Philippines, Poland, Russia, South Africa, Taiwan, Thailand,
Turkey, and Venezuela. "Free" MSCI indices exclude those shares not purchasable
by foreign investors. The Index does not include fees or expenses and is not
available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of Class A and Class B shares is 5/1/06. Index returns are based
on an inception date of 4/30/06.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is MFS(R) Emerging Markets Equity Portfolio,
which is diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

G. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

H. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

I. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

J. FORWARD COMMITMENTS, WHEN-ISSUED AND DELAYED DELIVERY SECURITIES - The
Portfolio may purchase securities on a when-issued or delayed delivery basis
and may purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the purchase
or sale commitment is made. The Portfolio may purchase securities under such
conditions only with the intention of actually acquiring them, but may enter
into a separate agreement to sell the securities before the settlement date.
Since the value of securities purchased may fluctuate prior to settlement, the
Portfolio may be required to pay more at settlement than the security is worth.
In addition, the purchaser is not entitled to any of the interest earned prior
to settlement. Upon making a commitment to purchase a security on a
when-issued, delayed delivery or forward commitment basis, the Portfolio will
hold liquid assets in a segregated account at the Portfolio's custodian bank
worth at least the equivalent of the amount due. The liquid assets will be
monitored on a daily basis and adjusted as necessary to maintain the necessary
value.

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

SUMMARY OF RESULTS

For the six months ended June 30, 2007, the MFS(R) Research International
Portfolio provided a total return of 10.44% for Class B. This compares with a
return of 11.09% for the Portfolio's benchmark, the MSCI EAFE(R) Index.

DETRACTORS FROM PERFORMANCE

Stock selection in the financial services sector detracted from performance
relative to the MSCI EAFE(R) Index. Aeon Credit Service (Japan), BOC Hong Kong,
and banking and financial services firm Sumitomo Mitsui Financial (Japan) were
among the portfolio's top detractors.

Stock selection in the leisure and autos and housing sectors also held back
relative performance. In the leisure sector, video game software company
Konami/(g)/ (Japan) hurt results. In the autos and housing sector, our
positioning in Honda Motor (Japan) and not owning strong-performing car maker
DaimlerChrysler (Germany) had a negative impact on relative returns.

Stocks in other sectors that dampened relative performance included electronics
manufacturers Samsung Electronics/(aa)/ (South Korea) and Funai Electric/(aa)/
(Japan). Not owning cellular phones maker Nokia (Finland) and mining operator
Rio Tinto (Australia), both benchmark constituents, also hurt as these stocks
outperformed the benchmark over the reporting period.

CONTRIBUTORS TO PERFORMANCE

Stock selection in the utilities and communications sector was the principal
contributor to performance relative to the MSCI EAFE(R) Index. Our holdings of
power and gas company E.ON/(aa)/ (Germany) was among the portfolio's top
contributors.

Stock selection in the basic materials sector aided relative returns. Mining
giant BHP Billiton (United Kingdom), industrial and medical gases producer
Linde (Germany), and steel products manufacturer Posco/(aa)(g)/ (South Korea)
helped drive the sector's positive results.

Stock selection in the health care sector also turned in a favorable relative
performance. Healthcare products maker Bayer (Germany) was the portfolio's top
contributing individual stock.

Elsewhere, our holdings of electronics and electrical engineering company
Siemens (Germany), mechanical engineering company GEA/(aa)/ (Germany), sporting
goods maker Adidas (Germany), and electrical distribution equipment
manufacturer Schneider Electric (France) bolstered relative performance. Not
owning weak-performing car maker Toyota (Japan) was another positive factor.

/(aa)/ Security is not a benchmark constituent.

/(g)/ Security was not held in the portfolio at period end.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The Morgan Stanley Capital International Europe, Australasia and Far East
Index ("MSCI EAFE(R) Index") is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance, excluding the US & Canada. The Index does not include fees or
expenses and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A shares is 5/1/01. Inception of the Class B shares
is 2/12/01. Inception of the Class E shares is 10/31/01. Index returns are
based on an inception date of 2/12/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is MFS(R) Research International Portfolio,
which is diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                     Expiring    Expiring    Expiring

MFS(R) Research International Portfolio $29,955,270 $11,883,462 $11,694,451 $6,377,357


MFS(R) Research International Portfolio acquired losses of $37,816,349 in the
merger with J.P. Morgan International Equity Portfolio on April 28th 2003 which
are subject to an annual limitation of $2,138,073.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. FUTURES CONTRACTS - A futures contract is an agreement involving the
delivery of a particular asset on a specified future date at an agreed upon
price. These contracts are generally used to provide the return of an index
without purchasing all of the securities underlying the index or as a temporary
substitute for purchasing or selling specific securities.

Upon entering into a futures contract, the Portfolio is required to make
initial margin deposits with the broker or segregate liquid investments to
satisfy the broker's margin requirements. Initial margin deposits are recorded
as assets and held in a segregated account at the custodian. During the period
the futures contract is open, changes in the value of the contract are
recognized as unrealized gains or losses by "marking to market" the contract on
a daily basis to reflect the value of the contract's settlement price at the
end of each day's trading. Variation margin payments are made or received and
recognized as assets due from or liabilities to the broker depending upon
whether unrealized gains or losses, respectively, are incurred. When the
contract is closed, the Portfolio records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
its basis in the contract.

Risks of entering into futures contracts include the possibility that there may
be an illiquid market and that the change in the value of the contract may not
correlate with changes in the value of the underlying securities.

G. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

H. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

of the loan would accrue to the account of the Portfolio. Risks of delay in
recovery of the securities or even loss of rights in the collateral may occur
should the borrower of the securities fail financially. Risks may also arise to
the extent that the value of the collateral decreases below the value of the
securities loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

J. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

K. FORWARD COMMITMENTS, WHEN-ISSUED AND DELAYED DELIVERY SECURITIES - The
Portfolio may purchase securities on a when-issued or delayed delivery basis
and may purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the purchase
or sale commitment is made. The Portfolio may purchase securities under such
conditions only with the intention of actually acquiring them, but may enter
into a separate agreement to sell the securities before the settlement date.
Since the value of securities purchased may fluctuate prior to settlement, the
Portfolio may be required to pay more at settlement than the security is worth.
In addition, the purchaser is not entitled to any of the interest earned prior
to settlement. Upon making a commitment to purchase a security on a
when-issued, delayed delivery or forward commitment basis, the Portfolio will
hold liquid assets in a segregated account at the Portfolio's custodian bank
worth at least the equivalent of the amount due. The liquid assets will be
monitored on a daily basis and adjusted as necessary to maintain the necessary
value.

L. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary

State Street Bank and Trust Company provides custodian and administration
services to the Trust. Effective April 30, 2007, Metropolitan Life Insurance
Company (MLIC) became the new transfer agent for the Trust. MLIC is an
affiliate of the Manager. MLIC receives no fees for its services to the Trust.
Prior to April 30, 2007, State Street Bank and Trust Company served as transfer
agent to the Trust.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a
percentage of the Portfolio's average daily net assets:

        MFS(R) Research International Portfolio  1.00%   1.25%   1.15%


If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing
distribution and shareholder servicing with respect to the Class B and Class E
Shares for such entities' fees or expenses incurred or paid in that regard.

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


SUMMARY OF RESULTS

For the six months ended June 30, 2007, the MFS(R) Value Portfolio had a total
return of 8.00%. This compares with a return of 6.23% for the Portfolio's
benchmark, the Russell 1000(R) Value Index.

CONTRIBUTORS TO PERFORMANCE

Stock selection and an underweighting in the weak-performing financial services
sector boosted performance relative to the Russell 1000(R) Value Index.
Avoiding financial services firm Wachovia and insurance firm American
International Group helped results as both stocks underperformed the benchmark
over the reporting period.

The combination of stock selection and an overweighted position in the
industrial goods and services sector aided relative returns. Top-contributing
holdings included agricultural equipment maker Deere, industrial machinery and
equipment manufacturer W.W. Grainger, and defense contractor Northrop Grumman.

Security selection in the consumer staples sector also benefited the
Portfolio's performance. Avoiding weak-performing household products maker
Procter & Gamble for a majority of the period positively affected the Portfolio.

Elsewhere, our holdings of integrated oil company TOTAL/*/, communications
services firm Vodafone/*/, global chemical company PPG Industries, and retailer
Nike/*/ were among the Portfolio's top contributing stocks.

DETRACTORS FROM PERFORMANCE

Stock selection in the health care sector negatively affected the Portfolio's
performance relative to the Russell 1000(R) Value Index. Our position in
weak-performing health care products maker Johnson & Johnson was among the
largest detractors from performance for the reporting period.

In the energy sector, an underweighted position in strong-performing oil and
gas giants Chevron and Exxon Mobil dampened relative results. Not owning
standout performers Valero Energy, Marathon Oil and Occidental Petroleum also
held back relative returns.

Stocks in other sectors that held back performance included an underweighted
position in telecommunications firm AT&T, and overweighted positions in
financial services company Allstate, home improvements product maker Masco and
defense contractor Lockheed Martin*.

+The chart reflects the performance of Class A shares of the Portfolio. This is
currently the only active Class in the Portfolio.

/1/The Russell 1000(R) Value Index is an unmanaged index which measures the
performance of those Russell 1000(R) Index companies with lower price-to-book
ratios and lower forecasted growth values. The Index does not include fees or
expenses and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gains distributions.

/3/Inception of Class A shares is 7/20/1998. Index returns are based on an
inception due of 7/31/1998.

Past Performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is MFS(R) Value Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A Shares are offered
by the Portfolio. Class B and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

8. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MANAGED BY NEUBERGER BERMAN MANAGEMENT, INC.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------

PORTFOLIO HIGHLIGHTS

Real estate investment trusts suffered through a difficult first half 2007 as
the FTSE NAREIT Equity REITs Index declined almost 6% at a time when stocks
generally provided positive returns. Key factors in the weakness of U.S. real
estate shares included higher credit spreads on commercial mortgage debt,
higher interest rates and "sector rotation" on the part of investors to more
global real estate companies away from domestically focused names. In this
environment, the Neuberger Berman Real Estate Portfolio modestly underperformed
its FTSE NAREIT benchmark.

The early weeks of the year were favorable for real estate stocks, as continued
earnings growth and extensive merger and acquisition activity helped them
advance modestly. However, real estate investment trusts (REITs) began to sell
off in February, along with the rest of the equity markets, on news of weakness
in the subprime lending sector. Later, further credit deterioration among
subprime loans widened credit spreads on securitized debt including commercial
mortgage securities. As a result, investors became more concerned that higher
borrowing costs might reduce mergers and acquisitions (M&A) activity, which has
been supportive of the public real estate markets. In addition, with relatively
healthy economic growth abroad, generalist investors sought global real estate
exposure, particularly at the expense of large-capitalization REITs, which
endured a sell-off in the second quarter.

Among the REIT sectors, Shopping Center stocks performed poorly amid concerns
about a potential consumer slowdown due to pressures from the weak housing
market, higher oil prices and stiffer lending rates. Health care issues also
lagged, as investors worried that higher interest rates would affect profits in
this rate-sensitive sector. The self storage sector trailed all other sectors.
The lodging/resorts sector outperformed for the period, providing positive
performance amid continued deal activity. The purchase of Hilton Hotels,
although not a REIT, reflected the overall interest from private buyers in
hotel shares. Specialty stocks also provided gains.

During the six-month reporting period, the Portfolio benefited from the strong
performance of a particular holding in the diversified sector, as well as an
underweight in the weak self storage sector. On the downside, stock selection
in Shopping Centers and an underweight in the outperforming specialty area
hampered results. An overweight and stock selection in the office sector was
also a negative. We continue to maintain an overweight in the Industrial and
Office sectors, where we expect good fundamentals, including rising occupancy
levels and rents as well as favorable earnings growth, for the balance of the
year.

OUTLOOK

Looking forward, the subprime mortgage market continues to be a significant
concern. With the presence of higher short-term interest rates, tighter lending
standards and softening housing markets, we anticipate that defaults and
delinquencies will increase. However, it bears noting that the payment history
for commercial real estate debt is favorable. Moreover, commercial real estate
fundamentals and credit quality have been strong and are likely to remain as
such.

Indeed, the majority of property markets in the United States can be described
as a "landlord's market." The core property sectors--Apartments, Office,
Industrial and Regional Malls/Shopping Centers--continued to show rising rents
and occupancy levels. Non-core areas--Health Care, Lodging/Resorts and Self
Storage--also exhibit sound fundamentals. In our view, the current environment
should translate into 7-8% earnings growth for REITs in 2007-08. In addition,
after a record setting six months for REIT transactions, we think that M&A
activity will continue to be strong.

Overall, we believe that attractive valuation levels and sound industry
fundamentals should begin to outweigh negative investor sentiment and continued
deterioration in the sub-prime residential mortgage market. REITs currently
trade at 7-10% discounts to net asset value, offer dividend yields of 4-5% and
are delivering above trend earnings growth. Still, we note that the domestic
REIT market is no longer a focal point of interest for many generalist
investors, which may limit gains in the coming quarters.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B and Class E
shares because of the difference in expenses paid by policyholders investing in
the different share class.

/1/The FTSE NAREIT Equity REIT Index is an unmanaged index that reflects
performance of all publicly traded equity REITs. The Index does not include
fees or expenses and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of Class A, B and E shares is 5/1/04. Index returns are based on
an inception date of 4/30/04.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Neuberger Berman Real Estate Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with Neuberger Berman Management, Inc., (the "Adviser") for investment advisory
services in connection with the investment management of the Portfolio.

Subject to the supervision and direction of the Board, the Manager supervises
the Adviser and has full discretion with respect to the retention or renewal of
the advisory agreement. The Manager pays the Adviser a fee based on the
Portfolio's average daily net assets.

affiliate of the Manager. MLIC receives no fees for its services to the Trust.
Prior to April 30, 2007, State Street Bank and Trust Company served as transfer

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a
percentage of the Portfolio's average daily net assets:

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution

subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

QUARTERLY PORTFOLIO SCHEDULE

The Trust files Form N-Q for the first and third quarters of each fiscal year.
The Trust's Forms N-Q will be available on the Securities and Exchange
Commission's website at http://www.sec.gov. The Trust's Forms N-Q may be

For the six month period ending June 30, 2007, the Portfolio outperformed both
the S&P 500(R) Index and the Russell 1000(R) Growth Index/1/.

During the reporting period, global economic growth, stable corporate earnings
and low inflation rates supported stock prices. However, related gains were
achieved in a somewhat volatile environment characterized by competing economic
forces. On the one hand, continued growth in the United States and the rest of
the world enabled many companies to report revenues and earnings that met or
exceeded expectations. Emerging markets produced especially strong returns,
fueled in large part by private equity investors with significant capital to
deploy. Conversely, the market was concerned about the prospect of rising
interest rates, volatile energy prices and potential inflation. In addition,
troubles with sub-prime mortgage lenders undermined the confidence of
investors, who worried that the impact of bad loans to credit-challenged
consumers could weigh on other parts of the market. Overall, however, solid
earnings and strong levels of liquidity generally proved positive for stocks.

Relative to the S&P 500(R) Index, the strongest contributors to return were
financials and information technology. Although financials yielded negative
market returns, strong stock selection delivered positive results to the
Portfolio, with relative outperformance supported by a sector underweight.
Similarly, both stock and sector selection contributed to relative returns in
technology. In contrast, a handful of our individual investments in the
consumer discretionary sector were disappointments and detracted from overall
performance.

Two large recent additions to the Portfolio were Boeing Co., the world's
leading aerospace company and the largest manufacturer of commercial jetliners
and military aircraft, and Costco Wholesale Corp., the largest wholesale retail
club operator in the United States. In our view, Boeing was selling for a
reasonable valuation, especially given what we believe is the company's
competitive advantage in the production of wide-body aircrafts. While we have
seen Costco as a successful retailer, more recently we have been encouraged by
its prospects for higher profit margins over the next few years--a step we felt
it has previously been unwilling to take in order to keep prices down.

One of the Portfolio's top performers was Apple, Inc. This computer and
personal electronics maker benefited from three ongoing trends: continued
growth in market share, strong sales of the IPOD digital music player, and the
eagerly anticipated release of the IPHONE. Another strong performer was
Monsanto Co., an agricultural company

whose seed and genomic products help farmers increase crop yields. The company
has benefited from high corn prices, which in turn have encouraged farmers to
look for ways to increase the productivity of their land. In the energy sector,
Schlumberger Ltd. continued to perform well. High oil prices have encouraged
companies to invest in new technologies to extract oil more efficiently, and
Schlumberger has been a direct beneficiary of this trend.

Corporate Executive Board (CEB), an information provider to large corporations
and nonprofit organizations, trailed our expectations. After the company
experienced some sales problems, it reported worse-than-expected earnings,
which weighed heavily on CEB's shares. Another underperformer was semiconductor
manufacturer Advanced Micro Devices, Inc. (AMD), which we sold from the
Portfolio during the period. AMD was facing a very tough competitive
environment, losing market share and struggling with a pricing war with its
much larger rival, Intel Corp. Also hurting performance was coffeehouse giant
Starbucks Corp., whose earnings lagged on higher-than-expected costs.

Regardless of the overall market backdrop, we will continue to follow our
bottom-up investment approach and favor companies that offer the potential for
sustainable earnings growth and at valuations that we believe are appropriate.
The Portfolio remains broadly diversified, and we continue to seek stocks
across a variety of sectors.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-value weighted index (stock price times number of shares outstanding),
with each stock's weight in the Index proportionate to its market value. The
Index does not include fees or expenses and is not available for direct
investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of Class A shares is 1/2/02. Inception of the Class B shares is
2/12/01. Inception of the Class E shares is 5/1/05. Index returns are based on
an inception date of 2/12/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Oppenheimer Capital Appreciation
Portfolio, which is diversified. Shares in the Trust are not offered directly
to the general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                                      12



                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                              Expiring
         Portfolio                                   Total   12/31/2010
         ---------                                  -------- ----------
                                                       

         Oppenheimer Capital Appreciation Portfolio $420,575  $420,575


Oppenheimer Capital Appreciation acquired losses of $2,062,652 in the merger
with Met/Putnam Research Portfolio on November 19, 2004 which are subject to a
limitation of $547,359.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

State Street Bank and Trust Company provides custodian and administration
services to the Trust. Effective April 30, 2007, Metropolitan Life Insurance
Company (MLIC) became the new transfer agent for the Trust. MLIC is an
affiliate of the Manager. MLIC receives no fees for its services to the Trust.
Prior to April 30, 2007, State Street Bank and Trust Company served as transfer
agent to the Trust.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a
percentage of the Portfolio's average daily net assets:

expenses in such subsequent year to exceed the Maximum Expense Ratio as stated
above. The Portfolio is not obligated to repay any expense paid by the Manager
more than five years after the end of the fiscal year in which such expense was
incurred.

For the period July 1, 2005 through October 31, 2006, if the average monthly
net assets of the Oppenheimer Capital Appreciation Portfolio were in excess of
$1 billion, a discount to the total fees for the Portfolio for that month of
2.5% was applied. Such fee was accrued daily and paid monthly by the tenth
business day following the end of the month in which such fee was accrued. If
OppenheimerFunds, Inc. ("Oppenheimer") shall serve for less than the whole of
any month, the foregoing compensation was prorated. For the purpose of
determining fees payable to Oppenheimer, the value of the Portfolio's net
assets was computed at the times and in the manner specified in the Trust's
Registration Statement.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to
activities primarily intended to result in the sale of Class B and Class E
Shares. However, under Class B and Class E Distribution Agreements, payments to
the Distributor for activities pursuant to the Class B Distribution Plan and
Class E Distribution Plan are currently limited to payments at an annual rate
equal to 0.25% and 0.15% of average daily net assets of the Portfolio
attributable to its Class B and Class E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing
distribution and shareholder servicing with respect to the Class B and Class E
Shares for such entities' fees or expenses incurred or paid in that regard.

During the year ended December 31, 2006 the Portfolio paid brokerage

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------

MAJOR MARKET TRENDS AFFECTING THE PORTFOLIO'S PERFORMANCE

Most fixed income sectors, including inflation-linked bonds (ILBs), showed
modest gains during the first half of 2006. During the second quarter of 2007
Treasury Inflation-Protection Protected Securities (TIPS) gave back some of
their gains from earlier in the year as worldwide growth and capital flows
drove real yields higher. The Lehman Brothers U.S. TIPS Index, returned a
modest 1.73 percent for the first six months of the year. The benchmark 10-year
TIPS issue yielded 2.67 percent as of the end of June, 46 basis points higher
than at the start of the second quarter. During the first quarter of 2007
economic data pointed toward slower growth, heightening market expectations for
Federal Reserve easing. During the second quarter the data, especially
employment statistics, gave little indication of economic weakness, causing
expectations of Fed easing to unwind and interest rates to move higher. Rates
also climbed in Europe and the U.K. as central banks there tightened to
forestall inflation. Another critical factor moving rates higher was the
market's anticipation of central bank reserve diversification away from
government bonds toward riskier assets. China's investment in a major U.S.
private equity firm raised investor awareness that there could be less demand
for Treasuries at the margin in the future. One consequence of institutional
investors seeking to get out ahead of this trend was the return of the term
premium to the U.S. yield curve late in the second quarter.

OTHER FACTORS ATTRIBUTED TO THE PORTFOLIO'S POSITIVE/NEGATIVE PERFORMANCE VS.
THE BENCHMARK

Below investment grade corporate bonds and locally issued emerging market bonds
held up better than their higher quality counterparts during difficult market
conditions in the first half of 2007. During the first quarter, an emphasis on
shorter maturity nominal bonds added to returns, while exposure to short
maturities via Eurodollar futures lost value during the second quarter as
expectations of Fed easing dimmed. Mortgage-backed bond returns lagged
Treasuries on a like-duration basis for the first six months of the year,
detracting from performance. While volatility in the mortgage market remained
near historic lows, mortgage yield premiums widened mainly due to reduced
demand from banks and other financial institutions. Exposure to short maturity
U.K. rates hurt performance as rates rose amid expectations of more rate hikes
by the Bank of England. Exposure to emerging market currencies helped
performance in the first half, while a position in the yen hurt performance.

MARKET/PORTFOLIO OUTLOOK

Real global growth will continue to advance at an annual rate of around 5
percent over the next several years, led by rapid expansion in developing
economies such as China and India. More mature developed economies will likely
grow at rates closer to 2 percent amid demographic and other challenges. The
U.S. economy will remain weak in 2007 and 2008. The soft domestic housing
market should feed into a broader economic slowdown, exacerbated by the sharp
increase in gasoline prices that should act as a tax on consumer demand. An
anticipated rise in unemployment and tame inflation should prompt Fed easing.
Non-dollar assets should outperform dollar-denominated investments since
relatively sluggish U.S. growth points to a weaker U.S. dollar and lower asset
price appreciation than in the rest of the world.

STRATEGY:

Key strategies will include:

..  REAL AND NOMINAL INTEREST RATE STRATEGIES--PIMCO will likely move total
   duration toward neutral reflecting the opposing forces of expected cyclical
   domestic weakness and continued secular global strength. Treasury Inflation
   Protected Securities (TIPS) duration will likely be maintained near the
   index with the potential for tactical overweights should inflation risks
   emerge. PIMCO will likely employ select non-US duration strategies given
   global relative value opportunities in U.S. dollar-hedged Japanese
   government bonds, which provide yield enhancement given interest rate
   differentials and short maturity U.K. nominal exposure, which may benefit as
   growth potentially slows through 2007.

..  YIELD CURVE--PIMCO will likely maintain a short-to- intermediate nominal
   focus in anticipation of a steeper yield curve. Over a cyclical time frame
   this steepening is likely to occur as the Fed cuts short-term rates later
   this year and early next year to stave off the negative impact of the
   housing downturn on the U.S. economy. Over a longer time horizon could also
   steepen as countries diversify currency reserves away from longer maturity
   Treasury bonds.

..  EMERGING MARKET BONDS--To participate in the rapid growth expected in
   developing economies, PIMCO will likely take exposure to locally issued
   emerging market bonds. Local Emerging Market (EM) bonds are poised for
   continued growth in new issuance, liquidity and investor participation.
   Their yields, many of which are in the high single digits, are likely to
   compress as economic fundamentals continue to improve. Yield premiums
   relative to Treasuries on local EM bonds tend to be more attractive than
   those on mostly dollar denominated, external emerging market debt, which
   already reflect the strong growth prospects for these economies.

..  CURRENCY--PIMCO will likely take advantage of expected weakness in the U.S.
   dollar by building currency positions, comprised largely of EM currencies.
   Local EM bonds, which are typically denominated in home country currencies,
   can be effective vehicles for taking EM currency exposure.

..  MORTGAGE AND CORPORATE EXPOSURE--While mortgages will remain an important
   source of high quality yield in portfolios, PIMCO will target reduced
   allocations and look to add value via security selection. Historically tight
   credit premiums point toward continued low exposure, as better opportunities
   to enhance yield exist elsewhere.

contained herein has been obtained from sources believed to be reliable, but
not guaranteed.

In an environment where interest rates may trend upward, rising rates will
negatively impact fixed income securities. Bonds with a longer duration (a
measure of the expected life of a security) tend to be more sensitive to
changes in interest rates, usually making them more volatile than securities
with shorter durations.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. Each sector of the bond
market entails risk. Municipals may realize gains and may incur a tax liability
from time to time. The guarantee on Treasuries, TIPS and Government Bonds is to
the timely repayment of principal and interest; shares of a portfolio that
invest in them are not guaranteed. Mortgage-backed securities are subject
prepayment risk. With corporate bonds there is no assurance that issuers will
meet their obligations. An investment in high-yield securities generally
involves greater risk to principal than an investment in higher-rated bonds.
Investing in non-U.S. securities may entail risk as a result of non-U.S.
economic and political developments, which may be enhanced when investing in
emerging markets.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B and Class E
shares because of the difference in expenses paid by policyholders investing in
the different share class.

/1/The Lehman Brothers Global Real: U.S. TIPS Index represents an unmanaged
market index made up of U.S. Treasury Inflation Linked Index securities. The
Index does not include fees or expenses and is not available for direct
investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of Class A and Class B shares is 5/1/03. Inception of Class E
shares is 5/1/06. Index returns are based on an inception date of 4/30/03.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

* Expenses are equal to the Portfolio's annualized expense ratio of 0.53%,
0.78%, and 0.68% for the Class A, Class B, and Class E, respectively,
multiplied by the average account value over the period, multiplied by 181/365
(to reflect the one-half year period).

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is PIMCO Inflation Protected Bond Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:

        PIMCO Inflation Protected Bond Portfolio $35,536,901 $35,536,901


E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. FUTURES CONTRACTS - A futures contract is an agreement involving the
delivery of a particular asset on a specified future date at an agreed upon
price. These contracts are generally used to provide the return of an index
without purchasing all of the securities underlying the index or as a temporary
substitute for purchasing or selling specific securities.

Upon entering into a futures contract, the Portfolio is required to make
initial margin deposits with the broker or segregate liquid investments to
satisfy the broker's margin requirements. Initial margin deposits are recorded
as assets and held in a segregated account at the custodian. During the period
the futures contract is open, changes in the value of the contract are
recognized as unrealized gains or losses by "marking to market" the contract on
a daily basis to reflect the value of the contract's settlement price at the
end of each day's trading. Variation margin payments are made or received and
recognized as assets due from or liabilities to the broker depending upon
whether unrealized gains or losses, respectively, are incurred. When the
contract is closed, the Portfolio records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
its basis in the contract.

Risks of entering into futures contracts include the possibility that there may
be an illiquid market and that the change in the value of the contract may not
correlate with changes in the value of the underlying securities.

G. OPTIONS CONTRACTS - A purchased option contract gives the buyer the right,
but not the obligation, to buy (call) or sell (put) an underlying item at a
fixed exercise price during a specified period. These contracts are generally
used by the Portfolio to provide the return of an index without purchasing all
of the securities underlying the index or as a substitute for purchasing or
selling specific securities.

Purchases of put and call options are recorded as investments, the value of
which are marked-to-market daily. When a purchased option expires, the
Portfolio will realize a loss equal to the premium paid. When the Portfolio
enters into a closing sale transaction, the Portfolio will realize a gain or
loss depending on whether the sales proceeds from the closing sale transaction
are greater or less than the cost of the option. When the Portfolio exercises a
put option, it will realize a gain or loss from the sale of the underlying
security and the proceeds from such sale will be decreased by the premium
originally paid. When the Portfolio exercises a call option, the cost of the
security which the Portfolio purchases upon exercise will be increased by the
premium originally paid.

The premium received for a written option is recorded as a liability. The
liability is marked-to-market daily based on the option's quoted market price.
When an option expires or the Portfolio enters into a closing purchase
transaction, the Portfolio realizes a gain (or loss if the cost of the closing
purchase transaction exceeds the premium received when the option was sold)
without regard to any unrealized gain or loss on the underlying security and
the liability related to such option is eliminated. When a written call option
is exercised, the Portfolio realizes a gain or loss from the sale of the
underlying security and the proceeds from such sale are increased by the
premium originally received. If a written put option is exercised, the amount
of the premium originally received will reduce the cost of the underlying
security purchased.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The risk associated with purchasing options is limited to the premium
originally paid. The risk in writing a call option is that the Portfolio may
forego the opportunity for profit if the market price of the underlying
security increases and the option is exercised. The risk in writing a put
option is that the Portfolio may incur a loss if the market price of the
underlying security decreases and the option is exercised. This loss can be
greater than premium received. In addition, the Portfolio could be exposed to
risks if the counterparties to the transactions are unable to meet the terms of
the contracts.

H. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

J. SHORT SALES - The Portfolio may enter into a "short sale" of securities in
circumstances in which, at the time the short position is open, the Portfolio
owns an equal amount of the securities sold short or owns preferred stocks or
debt securities, convertible or exchangeable without payment of further
consideration, into an equal number of securities sold short. This kind of
short sale, which is referred to as one "against the box," may be entered into
by the Portfolio to, for example, lock in a sale price for a security the
Portfolio does not wish to sell immediately.

The Portfolio may also make short sales of a security it does not own, in
anticipation of a decline in the market value of that security. To complete
such a transaction, the Portfolio must borrow the security to make delivery to
the buyer. The Portfolio then is obligated to replace the security borrowed by
purchasing it at market price at the time of replacement. The price at such
time may be more or less than the price at which the security was sold by the
Portfolio. Until the security is replaced, the Portfolio is required to pay to
the lender any dividends or interest which accrue during the period of the
loan. To borrow the security, the Portfolio also may be required to pay a
premium, which would increase the cost of the security sold. The proceeds of
the short sale will be retained by the broker, to the extent necessary to meet
margin requirements, until the short position is closed out. Until the
Portfolio replaces a borrowed security, the Portfolio will segregate with its
custodian, or earmark, cash or other liquid assets at such a level that (i) the
amount segregated, or earmarked, plus the amount deposited with the broker as
collateral will equal the current value of the security sold short and (ii) the
amount segregated plus the amount deposited with the broker as collateral will
not be less than the market value of the security at the time it was sold
short. The Portfolio will incur a loss as a result of the short sale if the
price of the security increases between the date of the short sale and the date
on which the Portfolio replaces the borrowed security. The Portfolio will
realize a gain if the security declines in price between those dates. This
result is the opposite of what one would expect from a cash purchase of a long
position in a security. The amount of any gain will be decreased, and the
amount of any loss increased, by the amount of any premium, dividends or
interest the Portfolio may be required to pay in connection with a short sale.
No more than one third of the Portfolio's net assets will be, when added
together: (i) deposited as collateral for the obligation to replace securities
borrowed to effect short sales; and (ii) segregated in connection with short
sales.

K. SWAP AGREEMENTS - The Portfolio may enter into swap contracts. Swap
contracts are derivatives in the form of a contract or other similar
instrument, which is an agreement to exchange the return generated by one
instrument for the return generated by another instrument. The payment streams
are calculated by reference to a specified index and agreed upon notional
amount. The term "specified index" includes, but is

not limited to, currencies, fixed interest rates, prices and total return on
interest rate indices, fixed income indices, stock indices and commodity
indices (as well as amounts derived from arithmetic operations on these
indices). For example, the Portfolio may agree to swap the return generated by
a fixed income index for the return generated by a second fixed income index.
The currency swaps in which the Portfolio may enter will generally involve an
agreement to pay interest streams in one currency based on a specified index in
exchange for receiving interest streams denominated in another currency. Such
swaps may involve initial and final exchanges that correspond to the agreed
upon notional amount. A Portfolio will usually enter into swaps on a net basis,
i.e., the two payment streams are netted out in a cash settlement on the
payment date or dates specified in the instrument, with the Portfolio receiving
or paying, as the case may be, only the net amount of the two payments. The
Portfolio's obligations under a swap agreement will be accrued daily (offset
against any amounts owing to the Portfolio) and any accrued by unpaid net
amounts owed to a swap counterparty will be covered by designating the
segregation, either on its records or with the Trust's custodian, of cash or
other liquid assets, to avoid any potential leveraging of the Portfolio. To the
extent that the net amounts owed to a swap counterparty are covered with such
liquid assets, the investment adviser believes such obligations do not
constitute "senior securities" under the 1940 Act and accordingly, the
investment adviser will not treat them as being subject to the Portfolio's
borrowing restrictions. The Portfolio may enter into OTC swap transactions with
counterparties that are approved by the investment adviser in accordance with
guidelines established by the Board. These guidelines provide for a minimum
credit rating for each counterparty and various credit enhancement techniques
(for example, collateralization of amounts due from counterparties) to limit
exposure to counterparties that have lower credit ratings.

The swaps in which the Portfolio may engage may include instruments under which
one party pays a single or periodic fixed amount(s) (or premium), and the other
party pays periodic amounts based on the movement of a specified index. Swaps
do not involve the delivery of securities, other underlying assets, or
principal. Accordingly, the risk of loss with respect to swaps is limited to
the net amount of payments the Portfolio is contractually obligated to make. If
the other party to a swap defaults, the Portfolio's risk of loss consists of
the net amount of payments that the Portfolio contractually is entitled to
receive. Currency swaps usually involve the delivery of the entire principal
value of one designated currency in exchange for the other designated currency.
Therefore, the entire principal value of a currency swap is subject to the risk
that the other party to the swap will default on its contractual delivery
obligations. If there is a default by the counterparty, the Portfolio may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of
banks and investment banking firms acting both as principals and as agents
utilizing standardized swap documentation. As a result, the swap market has
become relatively liquid. Certain swap transactions involve more recent
innovations for which standardized documentation has not yet been fully
developed and, accordingly, they are less liquid than traditional swap
transactions.

The use of swaps is a highly specialized activity that involves investment
techniques and risks different from those associated with ordinary portfolio
securities transactions. If an investment adviser is incorrect in its forecasts
of market values, interest rates, and currency exchange rates, the investment
performance of the Portfolio would be less favorable than it would have been if
this investment technique were not used.

Among the strategic transactions into which the Portfolio may enter are
interest rate swaps and the purchase or sale of related caps and floors. The
Portfolio may enter into these transactions primarily to manage its exposure to
interest rates, to protect against currency fluctuations, or to preserve a
return or spread on a particular investment. Interest rate swaps involve the
exchange by the Portfolio with another party of their respective commitments to
pay or receive interest, e.g., an exchange of floating rate payments for fixed
rate payments with respect to a notional amount of principal. A currency swap
is an agreement to exchange cash flows on a notional amount of two or more
currencies based on the relative value differential among them. An index swap
is an agreement to swap cash flows on a notional amount based on changes in the
values of the reference indices. The purchase of a cap entitles the purchaser,
to the extent that a specific index exceeds a predetermined interest rate, to
receive payments of interest on a notional principal amount from the party
selling such cap. The purchase of a floor entitles the purchaser to receive
payments on a notional principal amount from the party selling such floor to
the extent that a specified index falls below a predetermined interest rate or
amount.

In addition the Portfolio may enter into credit default swap contracts for
investment purposes. As the seller in a credit default swap contract, the
Portfolio would be required to pay the par (or other agreed upon) value of a
referenced debt obligation to the counterparty in the event of a default by a
third party, such as a U.S. or foreign corporate issuer, on the debt
obligation. In return, the Portfolio would receive from the counterparty a
periodic stream of payments over the term of the contract provided that no
event of default has occurred. If no default occurs, the Portfolio would keep
the stream of payments and would have no payment obligations. As the seller,
the Portfolio would be subject to investment exposure on the notional amount of
the swap. The Portfolio may also purchase credit default swap contracts in
order to hedge against the risk of default of debt securities held in its
portfolio, in which case the Portfolio would function as the counterparty
referenced in the preceding sentence. This would involve the risk that the
investment may expire worthless and would only generate income in the event of
an actual default by the issuer of the underlying obligation (as opposed to a
credit downgrade or other indication of financial instability). It would also
involve credit risk--the seller may fail to satisfy its payment obligations to
the Portfolio in the event of a default. Swap agreements are marked daily by
prices that are retrieved from independent pricing platforms (e.g. Bloomberg)
or from brokers. Fair values will be provided if independent prices are
unavailable. The change in value, if any, is recorded as unrealized gain or
loss in the Statement of Operations. A liquidation payment received or made at
the termination of the swap is recorded as realized gain or loss in the
Statement of Operations. Net periodic payments are included as part of realized
gain (loss) on the Statement of Operations.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

L. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

M. REVERSE REPURCHASE AGREEMENTS - The Portfolio may enter into reverse
repurchase agreements with brokers, dealers, domestic and foreign banks or
other financial institutions. In a reverse repurchase agreement, the Portfolio
sells a security and agrees to repurchase it at a mutually agreed upon date and
price, reflecting the interest rate effective for the term of the agreement. It
may also be viewed as the borrowing of money by the Portfolio. The Portfolio's
investment of the proceeds of a reverse repurchase agreement is the speculative
factor known as leverage. Leverage may cause any gains or losses of the
Portfolio to be magnified. The Portfolio may enter into a reverse repurchase
agreement only if the interest income from investment of the proceeds is
greater than the interest expense of the transaction and the proceeds are
invested for a period no longer than the term of the agreement. At the time the
Portfolio enters into a reverse repurchase agreement, it will earmark, or
establish and maintain a segregated account with an approved custodian
containing, cash or other liquid securities having a value not less than the
repurchase price (including accrued interest). If interest rates rise during a
reverse repurchase agreement, it may adversely affect the Portfolio's net asset
value. Reverse repurchase agreements are considered to be borrowings under the
1940 Act.

The assets contained in the segregated account will be marked-to-market daily
and additional assets will be placed in such account on any day in which the
assets fall below the repurchase price (plus accrued interest). The Portfolio's
liquidity and ability to manage its assets might be affected when it sets aside
cash or portfolio securities to cover such commitments. Reverse repurchase
agreements involve the risk that the market value of the securities retained in
lieu of sale may decline below the price of the securities the Portfolio has
sold but is obligated to repurchase. In the event the buyer of securities under
a reverse repurchase agreement files for bankruptcy or becomes insolvent, such
buyer or its trustee or receiver may receive an extension of time to determine
whether to enforce the Portfolio's obligation to repurchase the securities, and
a Portfolio's use of the proceeds of the reverse repurchase agreement may
effectively be restricted pending such decision.

N. FORWARD COMMITMENTS, WHEN-ISSUED AND DELAYED DELIVERY SECURITIES - The
Portfolio may purchase securities on a when-issued or delayed delivery basis
and may purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the purchase
or sale commitment is made. The Portfolio may purchase securities under such
conditions only with the intention of actually acquiring them, but may enter
into a separate agreement to sell the securities before the settlement date.
Since the value of securities purchased may fluctuate prior to settlement, the
Portfolio may be required to pay more at settlement than the security is worth.
In addition, the purchaser is not entitled to any of the interest earned prior
to settlement. Upon making a commitment to purchase a security on a
when-issued, delayed delivery or forward commitment basis, the Portfolio will
hold liquid assets in a segregated account at the Portfolio's custodian bank
worth at least the equivalent of the amount due. The liquid assets will be
monitored on a daily basis and adjusted as necessary to maintain the necessary
value.

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to Reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor

subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing

11. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

12. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MAJOR MARKET TRENDS AFFECTING THE PORTFOLIO'S PERFORMANCE

During the second quarter of 2007 bonds gave back much of their gains from
earlier in the year as worldwide growth and capital flows drove interest rates
higher. The Lehman Brothers Aggregate Bond Index, a widely used index of
high-grade bonds, managed a modest gain of 0.98 percent for the first six
months of the year. The benchmark 10-year Treasury bond yielded 5.03 percent as
of the end of June, 33 basis points higher than at the start of the year.
During the first quarter of 2007 economic data pointed toward slower growth,
heightening market expectations for Federal Reserve easing. During the second
quarter the data, especially employment statistics, gave little indication of
economic weakness, causing expectations of Fed easing to unwind and interest
rates to move higher. Rates also climbed in Europe and the U.K. as central
banks there tightened to forestall inflation. Another critical factor moving
rates higher was the market's anticipation of central bank reserve
diversification away from government bonds toward riskier assets. China's
investment in a major U.S. private equity firm raised investor awareness that
there could be less demand for Treasuries at the margin in the future. One
consequence of institutional investors seeking to get out ahead of this trend
was the return of the term premium to the U.S. yield curve late in the second
quarter. The Fed has remained on hold thus far in 2007, indicating a reluctance
to ease due to inflation concerns.

OTHER FACTORS ATTRIBUTED TO THE PORTFOLIO'S POSITIVE/NEGATIVE PERFORMANCE VS.
THE BENCHMARK

Below investment grade corporate bonds and locally issued emerging market bonds
held up better than their higher quality counterparts during difficult market
conditions in the first half of 2007. Above-index duration hurt performance
over the six-month period as interest rates rose. An emphasis on shorter
maturities was a positive, as yields on these bonds fell by more than those on
longer maturities. Mortgage-backed bond returns lagged Treasuries on a
like-duration basis for the first six months of the year. Returns from Treasury
Inflation Protected Securities (TIPS) and municipal bonds were mixed. TIPS
outpaced nominal bonds for the first half of 2007, as high gasoline prices
drove higher inflation accruals. Municipal bonds lagged taxable bonds for the
first half of 2007 after a difficult first quarter. Underweighting corporate
bonds was negative, as high grade corporates modestly outpaced Treasuries on a
like-duration basis for the first half of 2007. Holding emerging market bonds
added to performance, as they outperformed Treasuries for the first half of
2007. Government bonds around the world were under pressure amid the rise in
rates. U.S. Treasuries fared better than bonds of most developed economies for
the first six months of the year. Both the Bank of England and European Central
Bank raised rates during the first half of the year to quell inflation while
the Fed remained on hold.

MARKET/PORTFOLIO OUTLOOK

Real global growth should continue to advance at an annual rate of around 5
percent over the next several years, led by rapid expansion in developing
economies such as China and India. More mature developed economies will likely
grow at rates closer to 2 percent amid demographic and other challenges. The
U.S. economy should remain weak in 2007 and 2008. The downturn in the
residential property market has not found a bottom and the corresponding
influence on homeowners and consumers has yet to be fully realized. Non-dollar
assets should outperform dollar-denominated investments since relatively
sluggish U.S. growth points to a weaker U.S. dollar and lower asset price
appreciation than in the rest of the world.

STRATEGY:

Key strategies will include:

  .  INTEREST RATE STRATEGIES--PIMCO will likely reduce overall duration in
     anticipation of higher long-term rates over the next several years.
     However, we will likely maintain an overweight to shorter maturities in
     anticipation of a steeper yield curve. Over a cyclical time frame this
     steepening is likely to occur as the Fed cuts short-term rates later this
     year and early next to offset the negative impact of the housing downturn
     on the U.S. economy. Over a longer time horizon the yield curve could also
     steepen because of continued diversification away from longer maturity
     Treasury bonds by developing countries with large currency reserves.

  .  EMERGING MARKET BONDS--To participate in the rapid growth expected in
     developing economies, PIMCO will likely take exposure to locally issued
     emerging market bonds. Local EM bonds are poised for continued growth in
     new issuance, liquidity and investor participation. Their yields, many of
     which are in the high single digits, are likely to compress as economic
     fundamentals continue to improve. Yield premiums relative to Treasuries on
     local EM bonds tend to be more attractive than those on mostly dollar
     denominated, external emerging market debt, which already reflect the
     strong growth prospects for these economies.

  .  CURRENCY--PIMCO will likely take advantage of expected weakness in the
     U.S. dollar by building currency positions, comprised largely of EM
     currencies. Local EM bonds, which are typically denominated in home
     country currencies, can be effective vehicles for taking EM currency
     exposure.

  .  DEVELOPED NON-U.S. MARKETS--PIMCO will likely take exposure to short
     maturities in the U.K., where yields reflect more central bank tightening
     than we expect.

  .  MORTGAGE AND ASSET-BACKED BONDS--While mortgages will remain an important
     source of high quality yield in portfolios, PIMCO will target neutral
     allocations versus the index and look to add value via security selection.
     In the case of asset-backed bonds such as those backed by home equity
     loans, PIMCO will continue to emphasize the highest quality short-term
     issues that offer credit enhancement and payment priority.

  .  CORPORATES--Historically tight credit premiums point toward a continued
     underweight of this sector, as better opportunities to enhance yield exist
     elsewhere.

In an environment where interest rates may trend upward, rising rates will
negatively impact fixed income securities. Bonds with a longer duration (a
measure of the expected life of a security) tend to be more sensitive to
changes in interest rates, usually making them more volatile than securities
with shorter durations.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. Each sector of the bond
market entails risk. Municipals may realize gains and may incur a tax liability
from time to time. The guarantee on Treasuries, TIPS and Government Bonds is to
the timely repayment of principal and interest, shares of a portfolio that
invest in them are not guaranteed. Mortgage-backed securities are subject
prepayment risk. With corporate bonds there is no assurance that issuers will
meet their obligations. An investment in high-yield securities generally
involves greater risk to principal than an investment in higher-rated bonds.
Investing in non-U.S. securities may entail risk as a result of non-U.S.
economic and political developments, which may be enhanced when investing in
emerging markets.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The Lehman Brothers Aggregate Bond Index represents securities that are U.S.
domestic, taxable, non-convertible and dollar denominated. The Index covers the
investment grade fixed rate bond market, with index components for government
and corporate securities, mortgage pass-through securities, and asset-backed
securities. The Index does not include fees or expenses and is not available
for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A shares is 5/1/01. Inception of the Class B shares
is 2/12/01. Inception of the Class E shares is 10/31/01. Index returns are
based on an inception date of 1/31/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

0.78%, and 0.68% for the Class A, Class B, and Class E, respectively,
multiplied by the average account value over the period, multiplied by 181/365
(to reflect the one-half year period).

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is PIMCO Total Return Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                        Expiring

              PIMCO Total Return Portfolio $11,799,340 $11,799,340


E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. FUTURES CONTRACTS - A futures contract is an agreement involving the
delivery of a particular asset on a specified future date at an agreed upon
price. These contracts are generally used to provide the return of an index
without purchasing all of the securities underlying the index or as a temporary
substitute for purchasing or selling specific securities.

Upon entering into a futures contract, the Portfolio is required to make
initial margin deposits with the broker or segregate liquid investments to
satisfy the broker's margin requirements. Initial margin deposits are recorded
as assets and held in a segregated account at the custodian. During the period
the futures contract is open, changes in the value of the contract are
recognized as unrealized gains or losses by "marking to market" the contract on
a daily basis to reflect the value of the contract's settlement price at the
end of each day's trading. Variation margin payments are made or received and
recognized as assets due from or liabilities to the broker depending upon
whether unrealized gains or losses, respectively, are incurred. When the
contract is closed, the Portfolio records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
its basis in the contract.

Risks of entering into futures contracts include the possibility that there may
be an illiquid market and that the change in the value of the contract may not
correlate with changes in the value of the underlying securities.

G. OPTIONS CONTRACTS - A purchased option contract gives the buyer the right,
but not the obligation, to buy (call) or sell (put) an underlying item at a
fixed exercise price during a specified period. These contracts are generally
used by the Portfolio to provide the return of an index without purchasing all
of the securities underlying the index or as a substitute for purchasing or
selling specific securities.

Purchases of put and call options are recorded as investments, the value of
which are marked-to-market daily. When a purchased option expires, the
Portfolio will realize a loss equal to the premium paid. When the Portfolio
enters into a closing sale transaction, the Portfolio will realize a gain or
loss depending on whether the sales proceeds from the closing sale transaction
are greater or less than the cost of the option. When the Portfolio exercises a
put option, it will realize a gain or loss from the sale of the underlying
security and the proceeds from such sale will be decreased by the premium
originally paid. When the Portfolio exercises a call option, the cost of the
security which the Portfolio purchases upon exercise will be increased by the
premium originally paid.

The premium received for a written option is recorded as a liability. The
liability is marked-to-market daily based on the option's quoted market price.
When an option expires or the Portfolio enters into a closing purchase
transaction, the Portfolio realizes a gain (or loss if the cost of the closing
purchase transaction exceeds the premium received when the option was sold)
without regard to any unrealized gain or loss on the underlying security and
the liability related to such option is eliminated. When a written call option
is exercised, the Portfolio realizes a gain or loss from the sale of the
underlying security and the proceeds from such sale are increased by the
premium originally received. If a written put option is exercised, the amount
of the premium originally received will reduce the cost of the underlying
security purchased.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The risk associated with purchasing options is limited to the premium
originally paid. The risk in writing a call option is that the Portfolio may
forego the opportunity for profit if the market price of the underlying
security increases and the option is exercised. The risk in writing a put
option is that the Portfolio may incur a loss if the market price of the
underlying security decreases and the option is exercised. This loss can be
greater than premium received. In addition, the Portfolio could be exposed to
risks if the counterparties to the transactions are unable to meet the terms of
the contracts.

H. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

J. SHORT SALES - The Portfolio may enter into a "short sale" of securities in
circumstances in which, at the time the short position is open, the Portfolio
owns an equal amount of the securities sold short or owns preferred stocks or
debt securities, convertible or exchangeable without payment of further
consideration, into an equal number of securities sold short. This kind of
short sale, which is referred to as one "against the box," may be entered into
by the Portfolio to, for example, lock in a sale price for a security the
Portfolio does not wish to sell immediately.

The Portfolio may also make short sales of a security it does not own, in
anticipation of a decline in the market value of that security. To complete
such a transaction, the Portfolio must borrow the security to make delivery to
the buyer. The Portfolio then is obligated to replace the security borrowed by
purchasing it at market price at the time of replacement. The price at such
time may be more or less than the price at which the security was sold by the
Portfolio. Until the security is replaced, the Portfolio is required to pay to
the lender any dividends or interest which accrue during the period of the
loan. To borrow the security, the Portfolio also may be required to pay a
premium, which would increase the cost of the security sold. The proceeds of
the short sale will be retained by the broker, to the extent necessary to meet
margin requirements, until the short position is closed out. Until the
Portfolio replaces a borrowed security, the Portfolio will segregate with its
custodian, or earmark, cash or other liquid assets at such a level that (i) the
amount segregated, or earmarked, plus the amount deposited with the broker as
collateral will equal the current value of the security sold short and (ii) the
amount segregated plus the amount deposited with the broker as collateral will
not be less than the market value of the security at the time it was sold
short. The Portfolio will incur a loss as a result of the short sale if the
price of the security increases between the date of the short sale and the date
on which the Portfolio replaces the borrowed security. The Portfolio will
realize a gain if the security declines in price between those dates. This
result is the opposite of what one would expect from a cash purchase of a long
position in a security. The amount of any gain will be decreased, and the
amount of any loss increased, by the amount of any premium, dividends or
interest the Portfolio may be required to pay in connection with a short sale.
No more than one third of the Portfolio's net assets will be, when added
together: (i) deposited as collateral for the obligation to replace securities
borrowed to effect short sales; and (ii) segregated in connection with short
sales.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


K. SWAP AGREEMENTS - The Portfolio may enter into swap contracts. Swap
contracts are derivatives in the form of a contract or other similar
instrument, which is an agreement to exchange the return generated by one
instrument for the return generated by another instrument. The payment streams
are calculated by reference to a specified index and agreed upon notional
amount. The term "specified index" includes, but is not limited to, currencies,
fixed interest rates, prices and total return on interest rate indices, fixed
income indices, stock indices and commodity indices (as well as amounts derived
from arithmetic operations on these indices). For example, the Portfolio may
agree to swap the return generated by a fixed income index for the return
generated by a second fixed income index. The currency swaps in which the
Portfolio may enter will generally involve an agreement to pay interest streams
in one currency based on a specified index in exchange for receiving interest
streams denominated in another currency. Such swaps may involve initial and
final exchanges that correspond to the agreed upon notional amount. A Portfolio
will usually enter into swaps on a net basis, i.e., the two payment streams are
netted out in a cash settlement on the payment date or dates specified in the
instrument, with the Portfolio receiving or paying, as the case may be, only
the net amount of the two payments. The Portfolio's obligations under a swap
agreement will be accrued daily (offset against any amounts owing to the
Portfolio) and any accrued but unpaid net amounts owed to a swap counterparty
will be covered by designating the segregation, either on its records or with
the Trust's custodian, of cash or other liquid assets, to avoid any potential
leveraging of the Portfolio. To the extent that the net amounts owed to a swap
counterparty are covered with such liquid assets, the investment adviser
believes such obligations do not constitute "senior securities" under the 1940
Act and accordingly, the investment adviser will not treat them as being
subject to the Portfolio's borrowing restrictions. The Portfolio may enter into
OTC swap transactions with counterparties that are approved by the investment
adviser in accordance with guidelines established by the Board. These
guidelines provide for a minimum credit rating for each counterparty and
various credit enhancement techniques (for example, collateralization of
amounts due from counterparties) to limit exposure to counterparties that have
lower credit ratings.

The swaps in which the Portfolio may engage may include instruments under which
one party pays a single or periodic fixed amount(s) (or premium), and the other
party pays periodic amounts based on the movement of a specified index. Swaps
do not involve the delivery of securities, other underlying assets, or
principal. Accordingly, the risk of loss with respect to swaps is limited to
the net amount of payments the Portfolio is contractually obligated to make. If
the other party to a swap defaults, the Portfolio's risk of loss consists of
the net amount of payments that the Portfolio contractually is entitled to
receive. Currency swaps usually involve the delivery of the entire principal
value of one designated currency in exchange for the other designated currency.
Therefore, the entire principal value of a currency swap is subject to the risk
that the other party to the swap will default on its contractual delivery
obligations. If there is a default by the counterparty, the Portfolio may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of
banks and investment banking firms acting both as principals and as agents
utilizing standardized swap documentation. As a result, the swap market has
become relatively liquid. Certain swap transactions involve more recent
innovations for which standardized documentation has not yet been fully
developed and, accordingly, they are less liquid than traditional swap
transactions.

The use of swaps is a highly specialized activity that involves investment
techniques and risks different from those associated with ordinary portfolio
securities transactions. If an investment adviser is incorrect in its forecasts
of market values, interest rates, and currency exchange rates, the investment
performance of the Portfolio would be less favorable than it would have been if
this investment technique were not used.

Among the strategic transactions into which the Portfolio may enter are
interest rate swaps and the purchase or sale of related caps and floors. The
Portfolio may enter into these transactions primarily to manage its exposure to
interest rates, to protect against currency fluctuations, or to preserve a
return or spread on a particular investment. Interest rate swaps involve the
exchange by the Portfolio with another party of their respective commitments to
pay or receive interest, e.g., an exchange of floating rate payments for fixed
rate payments with respect to a notional amount of principal. A currency swap
is an agreement to exchange cash flows on a notional amount of two or more
currencies based on the relative value differential among them. An index swap
is an agreement to swap cash flows on a notional amount based on changes in the
values of the reference indices. The purchase of a cap entitles the purchaser,
to the extent that a specific index exceeds a predetermined interest rate, to
receive payments of interest on a notional principal amount from the party
selling such cap. The purchase of a floor entitles the purchaser to receive
payments on a notional principal amount from the party selling such floor to
the extent that a specified index falls below a predetermined interest rate or
amount.

In addition the Portfolio may enter into credit default swap contracts for
investment purposes. As the seller in a credit default swap contract, the
Portfolio would be required to pay the par (or other agreed upon) value of a
referenced debt obligation to the counterparty in the event of a default by a
third party, such as a U.S. or foreign corporate issuer, on the debt
obligation. In return, the Portfolio would receive from the counterparty a
periodic stream of payments over the term of the contract provided that no
event of default has occurred. If no default occurs, the Portfolio would keep
the stream of payments and would have no payment obligations. As the seller,
the Portfolio would be subject to investment exposure on the notional amount of
the swap. The Portfolio may also purchase credit default swap contracts in
order to hedge against the risk of default of debt securities held in its
portfolio, in which case the Portfolio would function as the counterparty
referenced in the preceding paragraph. This would involve the risk that the
investment may expire worthless and would only generate income in the event of
an actual default by the issuer of the underlying obligation (as opposed to a
credit downgrade or other indication of financial instability). It would also
involve credit risk--the seller may fail to satisfy its payment obligations to
the Portfolio in the event of a default. Swap agreements are marked daily by
prices that are retrieved from independent pricing platforms (e.g. Bloomberg)
or from brokers. Fair values will be provided if independent prices

are unavailable. The change in value, if any, is recorded as unrealized gain or
loss in the Statement of Operations. A liquidation payment received or made at
the termination of the swap is recorded as realized gain or loss in the
Statement of Operations. Net periodic payments are included as part of realized
gain (loss) on the Statement of Operations.

L. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

M. REVERSE REPURCHASE AGREEMENTS - The Portfolio may enter into reverse
repurchase agreements with brokers, dealers, domestic and foreign banks or
other financial institutions. In a reverse repurchase agreement, the Portfolio
sells a security and agrees to repurchase it at a mutually agreed upon date and
price, reflecting the interest rate effective for the term of the agreement. It
may also be viewed as the borrowing of money by the Portfolio. The Portfolio's
investment of the proceeds of a reverse repurchase agreement is the speculative
factor known as leverage. Leverage may cause any gains or losses of the
Portfolio to be magnified. The Portfolio may enter into a reverse repurchase
agreement only if the interest income from investment of the proceeds is
greater than the interest expense of the transaction and the proceeds are
invested for a period no longer than the term of the agreement. At the time the
Portfolio enters into a reverse repurchase agreement, it will earmark, or
establish and maintain a segregated account with an approved custodian
containing, cash or other liquid securities having a value not less than the
repurchase price (including accrued interest). If interest rates rise during a
reverse repurchase agreement, it may adversely affect the Portfolio's net asset
value. Reverse repurchase agreements are considered to be borrowings under the
1940 Act.

The assets contained in the segregated account will be marked-to-market daily
and additional assets will be placed in such account on any day in which the
assets fall below the repurchase price (plus accrued interest). The Portfolio's
liquidity and ability to manage its assets might be affected when it sets aside
cash or portfolio securities to cover such commitments. Reverse repurchase
agreements involve the risk that the market value of the securities retained in
lieu of sale may decline below the price of the securities the Portfolio has
sold but is obligated to repurchase. In the event the buyer of securities under
a reverse repurchase agreement files for bankruptcy or becomes insolvent, such
buyer or its trustee or receiver may receive an extension of time to determine
whether to enforce the Portfolio's obligation to repurchase the securities, and
a Portfolio's use of the proceeds of the reverse repurchase agreement may
effectively be restricted pending such decision.

N. FORWARD COMMITMENTS, WHEN-ISSUED AND DELAYED DELIVERY SECURITIES - The
Portfolio may purchase securities on a when-issued or delayed delivery basis
and may purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the purchase
or sale commitment is made. The Portfolio may purchase securities under such
conditions only with the intention of actually acquiring them, but may enter
into a separate agreement to sell the securities before the settlement date.
Since the value of securities purchased may fluctuate prior to settlement, the
Portfolio may be required to pay more at settlement than the security is worth.
In addition, the purchaser is not entitled to any of the interest earned prior
to settlement. Upon making a commitment to purchase a security on a
when-issued, delayed delivery or forward commitment basis, the Portfolio will
hold liquid assets in a segregated account at the Portfolio's custodian bank
worth at least the equivalent of the amount due. The liquid assets will be
monitored on a daily basis and adjusted as necessary to maintain the necessary
value.

O. MORTGAGE DOLLAR ROLLS - PIMCO Total Return Portfolio may enter into dollar
rolls in which the Portfolio sells mortgage-backed securities for delivery in
the current month and simultaneously contracts to repurchase substantially
similar (same type, coupon and maturity) securities to settle on a specified
future date. During the roll period, the Portfolio forgoes principal and
interest paid on the securities. The Portfolio is compensated by a fee paid by
the counterparty, often in the form of a drop in the repurchase price of the
securities. Dollar rolls are accounted for as financing arrangements; the fee
is accrued into interest income ratably over the term of the dollar roll and
any gain or loss on the roll is deferred and realized upon disposition of the
rolled security. The average monthly balance of dollar rolls outstanding during
the period ended June 30, 2007 was approximately $1,163,887,870.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

services to the Trust. Effective April 30, 2007, Metropolitan Life Insurance
Company (MLIC) became the new transfer agent for the Trust. MLIC is an
affiliate of the Manager. MLIC receives no fees for its services to the Trust.
Prior to April 30, 2007, State Street Bank and Trust Company served as transfer
agent to the Trust.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing
distribution and shareholder servicing with respect to the Class B and Class E
Shares for such entities' fees or expenses incurred or paid in that regard.

11. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

12. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MANAGED BY PIONEER INVESTMENT MANAGEMENT, INC.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------

FIRST HALF MARKET REVIEW

After having eked out a marginally positive return in the first quarter, the
S&P 500(R) Index posted a solid gain in the second quarter despite slower GDP
growth and rising bond yields. The S&P 500(R) Index returned 7% in the first
half, with its energy (up 17%), materials (16%), and telecom services
(15%) leading while the financials (-1%) and consumer discretionary
(3%) sectors were its worst performers.

SECOND QUARTER PERFORMANCE REVIEW

Pioneer Fund Portfolio shares returned 7.90% at net asset value in the first
half of 2007, compared to 6.96% for the benchmark S&P 500(R) Index.

Returns benefited most from good stock selection in the industrials, materials,
and consumer discretionary sectors and an underweight in financials.

In the consumer discretionary sector, efficiency and building parts supplier
Johnson Controls returned 36% primarily driven by profits in its Building
Controls business, which has benefited from the strength of U.S. construction
spending.

In industrials, heavy truck maker PACCAR, farm equipment maker Deere, and
Caterpillar truckmaker PACCAR each returned over 25% on continued strong
business conditions and operating results. All three are benefiting from strong
demand--PACCAR due to a strong overall economy, Deere from an increase in farm
equipment demand linked to rising corn prices and ethanol demand, and
Caterpillar from strength in a number of its end markets.

In the materials sector, diversified mining company Rio Tinto and aluminum
producer Alcoa each returned over 35%. Merger and acquisition activity in the
mining industry continues, stimulating investor interest in the group, and
metal prices remain firm.

The largest drag on performance was the energy sector, as rising oil prices
penalized both our underweight of the energy sector and selection strategy
within the sector. We have been surprised by the continuing strength in oil
prices, and have not been positioned for rising prices.

CURRENT OUTLOOK AND POSITIONING

The U.S. economy continues to behave in line with our expectations, slowing
without falling into recession. While there are sources of concern, equity
valuations remain quite reasonable, and we continue to expect single-digit
profit growth and interest rates near current levels for the remainder of the
year. We have rather moderate expectations for this year but are looking ahead
to positioning the portfolio for next year as we move through this year.

Over the last couple of years, it's been very much an old economy-focused
market with cyclicals, materials and industrials doing very well, but we expect
a shift in investor preferences toward consumer staples and less cyclically
sensitive stocks, and consumer staples now represents one of our most
overweighted sectors. While we continue to have significant positions in
industrials and materials companies, and while these positions have been key
contributors to performance, we're increasingly cautious on some of the
cyclicals that have done so well. We're avoiding companies with overly
leveraged balance sheets, and we're very conscious of earnings and the
sensitivity of the market to earnings announcements.

The financials sector represents our largest underweight relative to the S&P
500(R) index. Later in the year, the sector may present some opportunities, but
we remain cautious for the time being, because of credit quality concerns and
tight lending margins. It may still be six to twelve months before the coast is
clear there, but the companies that make their way through this difficult time
should be in pretty good shape for the upturn. Keep in mind, you always want to
be looking ahead six to nine to twelve months, rather than focusing on the
immediate environment.

At June 30, we are also underweighted energy and utilities relative to the S&P
500(R) Index. As noted above, oil company stocks appear richly valued barring a
forecast of rising oil prices, but we believe oil prices are higher than is
justified by underlying supply, demand, and inventory conditions and that
prices would be lower than they are if it weren't for the tension in the Middle
East. Utilities, particularly electric utilities appear very richly valued
given their modest earnings and dividend growth prospects.

SINCERELY,

+The chart reflects the performance of Class A shares of the Portfolio. This is
currently the only active Class in the Portfolio.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 chosen for
market size, liquidity, and industry group representation. It is a market-value
weighted index (stock price times number of shares outstanding), with each
stock's weight in the Index proportionate to its market value. The Index does
not include fees and expenses and is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gains distributions.

/3/Inception of Class A shares is 12/31/1994. Index returns are based on an
inception date of 12/31/1994.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Pioneer Fund Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A Shares are offered
by the Portfolio. Class B and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                Expiring   Expiring
            Portfolio                 Total    12/31/2010 12/31/2011

            Pioneer Fund Portfolio $11,243,971 $9,959,689 $1,284,282


On May 1, 2006, the Pioneer Fund Portfolio, a series of The Travelers Series
Trust, was reorganized into the Pioneer Fund Portfolio a series of Met
Investors Series Trust. The Portfolio acquired capital losses of $13,217,771.
The losses incurred by the Portfolio are subject to an annual limitation of
$1,630,787.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the

8. RECENT ACCOUNTING PRONOUNCEMENTS


On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MARKET REVIEW

The first half of 2007 in the U.S. fixed income market was dominated by two
issues: the anticipated easing of rates by the Federal Reserve and worries
about the U.S. housing and sub-prime market. Contrary to our view, investors
expected the Fed to cut rates at the beginning of 2007, due to weak economic
growth and controlled inflation. Indeed, these expectations seemed to be
confirmed by anemic first quarter GDP growth (ultimately determined to be
0.7%), which resulted from a large inventory correction and a slowdown in
housing and in government spending. As it became evident that second quarter
growth would more than compensate for the weakness of the first quarter
(current expectations are around 3.3%), the market unwound its expectations of
easing in May and June, with the 10 year Treasury rising from 4.70% at the
beginning of the year to 5.03% by the end of June. The yield curve inversion
lessened as the Fed remained on hold with the emergence of stronger growth.
Part of the fears regarding U.S. GDP growth centered on the weak U.S. housing
market, which gave rise to the second major concern of the first half: the
sub-prime market. Poor U.S. housing demand, reflected in lower housing permits
and new construction, and lower prices, has accelerated defaults among
sub-prime borrowers, highlighting the weak underwriting standards used to
extend these mortgage loans. Rising sub-prime defaults raised concerns about
CDO, hedge fund and financial institutions' exposure to these assets, and along
with increasing yields, brought about a flight to quality and aversion to risky
credit sectors in June.

The Lehman U.S. Universal Index returned 1.10% for the six month period.
Treasuries returned 1.0%, with dramatic differences along the yield curve, as
longer yields rose, reflecting changed interest rate expectations, and short
Treasuries benefited from the duration shortening trade and the flight to
quality in June. Investment grade corporates marginally outpaced Treasuries,
returning 3 basis points of excess return for the period. Particularly hard hit
in June were mortgages, which widened 4 basis points vs. swaps for a -53 basis
points excess return versus Treasuries for the month, their worst performance
since July 2003, resulting in a -57 excess return for the first half. U.S. high
yield, at a 3.0% return, was the best performing U.S. fixed income asset class
for the first half of 2007. The high yield markets benefited from improving
economic growth outlook and a 10 year low in default rates. High yield
performance for the period reflected its lower interest rate sensitivity, in an
environment of rising yields and stronger economic growth.

With respect to currencies and international fixed income, the U.S. dollar
declined against most major currencies except the Yen during the period,
reflecting continuing concerns about relative U.S. growth, trade and capital
flows, and the sub-prime impact on the credit and mortgage markets. The Euro
rose 3% and the Norwegian Krone rose 6.6%. The Japanese Yen declined 3.5% due
to continued uncertainty surrounding Japanese growth. International high yield
had strong performance, primarily due to strong currency returns, and emerging
markets debt, underperformed high yield, reflecting tight relative spreads and
increased risk aversion later in May and June.
PERFORMANCE REVIEW

Pioneer Strategic Income Portfolio returned 1.96% for the six months, compared
to the Lehman Brothers U.S. Universal Index return of 1.11%.

The primary contributors to our outperformance were our U.S. high yield
allocation and our short duration position. While we have reduced our global
high yield allocation over the past year to the current level of 27.5% in light
of tighter spreads, we continue to find value through bottom-up security
selection. We positioned our duration 0.3 years short, consistent with our view
that economic growth was strong and the Fed would not cut rates. Finally, our
currency positions generally helped performance, as the dollar weakened over
the period against most currencies except the Japanese Yen. Our TIPS overweight
vs. nominal Treasuries, focused in longer maturities, also helped performance.

Security positions that helped performance included our Norwegian Krone
position, which we pared down over the period as well as high yield issues True
Move and Intelsat. True Move, a Thai telecom provider, benefited from favorable
tax rulings affecting tariffs, and Intelsat was acquired by another private
equity firm. Securities that hurt performance included our Japanese Yen
position, in the face of a dollar rally against the Yen. In addition, our
Sallie Mae position declined on news of a leveraged buyout (which recent
reports indicate may fall through).

TRADING ACTIVITY

In response to the increase in Treasury yields, we extended the duration of the
portfolio to a near-neutral position to the index, primarily by adding lower
coupon mortgages. We also increased our inflation-linked position in the longer
end, as a hedge against increased inflation. At the sector level, we continued
to improve the quality of the portfolio and positioned it more defensively. We
have reduced our non-investment grade exposure with a corresponding increase in
our mortgage exposure. We have also increased our loan exposure within our high
yield allocation, gaining seniority in the capital structure. Significant
security level additions included Community Health Systems, and Algoma Steel;
security sales included Celanese (bond tender), Gazprom, Kabel Deutschland and
Noble Group.

CURRENT OUTLOOK AND POSITIONING

We believe the U.S. economy will experience good growth for the year. We
therefore continue to believe the Fed will not cut rates in 2007, and that
long-term U.S. interest rates will remain in a trading range.

Given solid economic growth prospects and sufficient market liquidity, we
believe high yield can continue to deliver above-market performance and
continue to hold high yield and, to a lesser extent, emerging markets
positions, but we have been reducing exposure as narrower relative yields
reduce relative their attractiveness.

We continue to favor mortgages over investment grade corporate bonds, because
they offer comparable yield without incurring the credit risk associated with
LBO and share buyback corporate actions. Finally, we favor inflation-protected
securities (TIPS) as a hedge against an overheating economy and rising
inflation.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Pioneer Strategic Income Portfolio, which
is non-diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A Shares are offered
by the Portfolio. Class B and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

On May 24, 2006, the Board of Trustees of the Trust approved the change of the
fiscal year end from October 31 to December 31. The Portfolio's change of the
fiscal year end became effective on November 1, 2006.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED - CONTINUED


B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                Expiring   Expiring   Expiring   Expiring

- ---------                          ----------- ---------- ---------- ---------- -----------
                                                                 

Pioneer Strategic Income Portfolio $27,677,097 $3,523,658 $3,076,895 $7,414,445 $13,662,099


On May 1, 2006, the Portfolio, a series of The Travelers Series Trust, was
reorganized into the Portfolio, a series of Met Investors Series Trust. The
Portfolio acquired capital losses of $28,401,723. The losses incurred by the
Portfolio are subject to an annual limitation of $6,843,272.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

                                      20



                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

H. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

I. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

J. FORWARD COMMITMENTS, WHEN-ISSUED AND DELAYED DELIVERY SECURITIES - The
Portfolio may purchase securities on a when-issued or delayed delivery basis
and may purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the purchase
or sale commitment is made. The Portfolio may purchase securities under such
conditions only with the intention of actually acquiring them, but may enter
into a separate agreement to sell the securities before the settlement date.
Since the value of securities purchased may fluctuate prior to settlement, the
Portfolio may be required to pay more at settlement than the security is worth.
In addition, the purchaser is not entitled to any of the interest earned prior
to settlement. Upon making a commitment to purchase a security on a
when-issued, delayed delivery or forward commitment basis, the Portfolio will
hold liquid assets in a segregated account at the Portfolio's custodian bank
worth at least the equivalent of the amount due. The liquid assets will be
monitored on a daily basis and adjusted as necessary to maintain the necessary
value.

K. STRIPPED SECURITIES - The Portfolio may invest in "Stripped Securities," a
term used collectively for certain structured fixed income securities. Stripped
securities can be principal only securities ("PO"), which are debt obligations
that have been stripped of unmatured interest coupons or interest only
securities ("IO"), which are unmatured interest coupons that have been stripped
from debt obligations. Stripped Securities do not make periodic payments of
interest prior to maturity. As is the case with all securities, the market
value of Stripped Securities will fluctuate in response to changes in economic
conditions, interest rates and the market's perception of the securities.
However, fluctuations in response to interest rates may be greater in Stripped
Securities than for debt obligations of comparable maturities that currently
pay interest. The amount of fluctuation increases with a longer period of
maturity.

The yield to maturity on IOs' is sensitive to the rate of principal repayments
(including prepayments) on the related underlying debt obligation and principal
payments may have a material effect on yield to maturity. If the underlying
debt obligation experiences greater than anticipated prepayments of principal,
the Portfolio may not fully recoup the initial investment in IOs'.

L. CREDIT AND MARKET RISK - The Portfolio may invest in high yield instruments
that are subject to certain credit and market risks. The yields of high yield
instruments reflect, among other things, perceived credit risk. The Portfolio's
investments in securities rated below investment grade typically involve risks
not associated with higher rated securities including, among others, greater
risk related to timely and ultimate payment of interest and principal, greater
market price volatility and less liquid secondary market trading.

M. LOAN PARTICIPATIONS - The Portfolio may invest in loans arranged through
private negotiation between one or more financial institutions. The Portfolios'
investment in any such loan may be in the form of a participation in or an
assignment of the loan. In connection with purchasing participations, the
Portfolio generally will have no right to enforce compliance by the borrower
with the terms of the loan agreement relating to the loan, nor any rights of
set-off against the borrower and the Portfolio may not benefit directly from
any collateral supporting the loan in which they have purchased the
participation.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The Portfolio will assume the credit risk of both the borrower and the lender
that is selling the participation. In the event of the insolvency of the lender
selling the participation, the Portfolio may be treated as a general creditor
of the lender and may not benefit from any set-off between the lender and the
borrower.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary

Prior to May 1, 2006, Travelers Asset Management International Company LLC
managed the investment operations of the Portfolio pursuant to a management
agreement entered into by The Travelers Series Trust on behalf of the
Portfolio. In addition, The Travelers Insurance Company acted as administrator
to the Portfolio.

State Street Bank and Trust Company provides custodian and administration
services to the Trust. Effective April 30, 2007, Metropolitan Life Insurance
Company (MLIC) became the new transfer agent for the Trust. MLIC is an
affiliate of the Manager. MLIC receives no fees for its services to the Trust.
Prior to April 30, 2007, State Street Bank and Trust Company served as transfer
agent to the Trust.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a
percentage of the Portfolio's average daily net assets:



                                                Maximum Expense Ratio

Income Portfolio were 1.50%, 1.75%, and 1.65% for Class A, B and E,
respectively.

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

9. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

10. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------

MANAGEMENT'S PERFORMANCE REVIEW

The RCM Technology Portfolio, Class A increased by +10.82% for the first six
months of 2007. The Portfolio outperformed its primary style benchmark, the
Goldman Sachs Technology Index ('GSTI')/1/ which returned 10.40%, as well as
its broad-market index, the S&P 500(R) Index, which returned 6.96%.

MARKET ENVIRONMENT

The first half of 2007 started off with investors concerned about the economy.
As the second quarter progressed, investors became enthusiastic about many
large cap technology stocks, such as IBM, Oracle, and Dell, which were not
holdings of the portfolio. Our focus for the RCM Technology Portfolio is on
mid-cap, higher-growth companies, and the portfolio's stock holdings generally
lagged those larger companies which appreciated more than those in the GSTI
Index.

North American markets continued to march higher despite a major move upward in
long term bond yields, continued weakness in housing, and high energy prices.
The first half ended with some volatility, given late quarter press citing the
near collapse of two mortgage-debt funds at Bear Stearns. Nonetheless, strong
global economies, favorable earnings, and record corporate buyout activity
supported strength during the first half of 2007. Finally, the market broadened
its interest into the higher growth companies in June, and the Portfolio passed
the indices for the year.

PORTFOLIO REVIEW

Positive stock selection was the major contributor to the portfolio's
performance during the first half of 2007. Most notably, strong stock-picking
in the consumer services, media and telecommunication services industries
proved to benefit the portfolio. Specific stocks that added the most value on
an absolute basis were Japanese-based Nintendo Co., Apple, Inc. and NII
Holdings. RCM's decision to overweight energy and materials and to underweight
software also proved to be successful strategies during this period.

The largest detractors to portfolio performance were some of the component
companies that are struggling with competition. On an absolute basis, Qlogic
Corp, Seagate Technology and Marvell Technology proved to be the biggest
negative contributors to performance.

From a geographical perspective, the portfolio benefited from positions in
European & Asian technology stocks. Strong stock selection within these areas
also helped performance. Our focus in Asia has been on components companies,
Chinese internet companies and gaming companies, and many of these have done
well despite some concerns about the regional currencies and economies. In
Europe, we have been focusing on the third generation cellular components and
alternative energy companies who are being driven by rapid adoption of these
two technologies in that region.
- --------
/1/ The Goldman Sachs Technology Index is a capitalization-weighted index
considered representative of the technology Industry. The Index does not
include fees or expenses and is not available for direct investment.
OUTLOOK

Earlier this year, we believed that the economy was weakening and that interest
rates would be cut, but now it appears that the economy has again resumed its
steady growth and interest rates have begun to rise. This steady growth should
help most technology companies at least meet expectations, and we are hopeful
that investors will continue to show interest in the higher growth companies.

We remain focused on growth sectors within technology, and we have seen a
compression in the difference between valuations of high and low growth
companies. We believe the large amount of cash available for buyouts has caused
investors to set a 'valuation floor' of multiples for most stocks. The higher
growth companies have seen their multiples continue to compress toward this
floor, despite their much higher growth rates than the economy. As investors
gain confidence about the economy, we think they will continue the recent trend
and buy these high growth companies.

Another factor is the multinational nature of our Portfolio's companies, most
of which have significant business outside the North America. That piece is
doing better than expected, helping many of these companies to ride through any
softness in the U.S. That performance is also helping bolster confidence in
these companies.

We remain enthusiastic about the fundamentals driving our companies,
historically low valuations for growth, and a number of strong product cycles
that are underway in the technology sector.

is 2/12/01. Inception of the Class E shares is 10/31/01. Index returns are
based on an inception date of 1/31/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is RCM Technology Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. OPTIONS CONTRACTS - A purchased option contract gives the buyer the right,
but not the obligation, to buy (call) or sell (put) an underlying item at a
fixed exercise price during a specified period. These contracts are generally
used by the Portfolio to provide the return of an index without purchasing all
of the securities underlying the index or as a substitute for purchasing or
selling specific securities.

Purchases of put and call options are recorded as investments, the value of
which are marked-to-market daily. When a purchased option expires, the
Portfolio will realize a loss equal to the premium paid. When the Portfolio
enters into a closing sale transaction, the Portfolio will realize a gain or
loss depending on whether the sales proceeds from the closing sale transaction
are greater or less than the cost of the option. When the Portfolio exercises a
put option, it will realize a gain or loss from the sale of the underlying
security and the proceeds from such sale will be decreased by the premium
originally paid. When the Portfolio exercises a call option, the cost of the
security which the Portfolio purchases upon exercise will be increased by the
premium originally paid.

The premium received for a written option is recorded as a liability. The
liability is marked-to-market daily based on the option's quoted market price.
When an option expires or the Portfolio enters into a closing purchase
transaction, the Portfolio realizes a gain (or loss if the cost of the closing
purchase transaction exceeds the premium received when the option was sold)
without regard to any unrealized gain or loss on the underlying security and
the liability related to such option is eliminated. When a written call option
is exercised, the Portfolio realizes a gain or loss from the sale of the
underlying security and the proceeds from such sale are increased by the
premium originally received. If a written put option is exercised, the amount
of the premium originally received will reduce the cost of the underlying
security purchased.

The risk associated with purchasing options is limited to the premium
originally paid. The risk in writing a call option is that the Portfolio may
forego the opportunity for profit if the market price of the underlying
security increases and the option is exercised. The risk in writing a put
option is that the Portfolio may incur a loss if the market price of the
underlying security decreases and the option is exercised. This loss can be
greater than premium received. In addition, the Portfolio could be exposed to
risks if the counterparties to the transactions are unable to meet the terms of
the contracts.

G. FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into forward
foreign currency contracts to hedge their portfolio holdings against future
movements in certain foreign currency exchange rates. A forward currency
contract is a commitment to purchase or sell a foreign currency at a future
date at a set price. The forward currency contracts are valued at the forward
rate and are marked-to-market daily. The change in market value is recorded by
the Portfolio as an unrealized gain or loss. When the contract is closed, the
Portfolio recognizes a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time
it was closed.

The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the securities of the Portfolio, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts to sell limit the risk of loss due to a
decline in the value of the currency holdings, they also limit any potential
gain that might result should the value of the currency increase. In addition,
the Portfolio could be exposed to risks if the counterparties to the contracts
are unable to meet the terms of the contracts.

H. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

J. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

K. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary

Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with RCM Capital Management LLC (the "Adviser") for investment advisory
services in connection with the investment management of the Portfolio.

Subject to the supervision and direction of the Board, the Manager supervises
the Adviser and has full discretion with respect to the retention or renewal of
the advisory agreement. The Manager pays the Adviser a fee based on the
Portfolio's average daily net assets.

Under the terms of the Portfolio's investment advisory agreement, the Portfolio
pays the Manager a monthly fee based upon annual rates applied to the
Portfolio's average daily net assets as follows:

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES -
CONTINUED


The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a
percentage of the Portfolio's average daily net assets:



                                          Maximum Expense Ratio
                                          under current Expense
                                          Limitation Agreement

                RCM Technology Portfolio  1.10%   1.35%   1.25%


If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing
distribution and shareholder servicing with respect to the Class B and Class E
Shares for such entities' fees or expenses incurred or paid in that regard.

the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MARKET OVERVIEW

Continuing the general trend of the past four years, financial markets
progressed markedly during the first half of 2007. Volatility returned to the
markets with episodic appearances over the past six months. Global markets
dropped sharply in February on fears of a slowdown in U.S. economic growth from
a subprime lending meltdown. Despite significant declines, markets recovered
sharply and ended the first quarter on a positive note. The advancement
continued during the second quarter as markets remained resilient and the Dow
and S&P 500 reached all-time highs. Year-to-date through June 30, the S&P
500(R) Index returned 6.9%, the S&P MidCap 400(R) Index returned 11.9%, and the
S&P SmallCap 600(R) Index returned 8.6%. Energy was the best performing sector
across large-cap and mid-cap stocks, while materials dominated in small-caps.
Financials were the biggest laggard across all market capitalizations. Foreign
stocks, as measured by the MSCI EAFE(R) Index, returned 10.7% in light of
continued strong economic growth abroad. Bonds underperformed equities with the
Lehman Brothers Aggregate Bond Index returning 0.98%.

PORTFOLIO OVERVIEW

For the six-month period ended June 30, 2007, the Portfolio (Class B) returned
6.78%, underperforming its blended benchmark which returned 7.19%. Most of the
underperformance was attributed to the Portfolio's mid-cap holdings as the
mid-cap value portion of the model, Neuberger Berman Mid Cap Value Portfolio*,
lagged the broad S&P MidCap 400(R) Index. The Portfolio's large-cap segment
also detracted, with Jennison Growth Portfolio and Van Kampen Comstock
Portfolio holding back returns as both lagged the broad S&P 500(R) Index.
Sources of strength for the period included the Portfolio's small-cap and
foreign holdings. Within small-cap, Franklin Templeton Small Cap Growth
Portfolio gained 10.18% during the period, outperforming the S&P SmallCap
600(R) Index by 1.62%. Within the foreign sleeve of the Portfolio, exposure to
emerging market equities had the greatest impact, with MFS(R) Emerging Markets
Equity Portfolio returning 14.58% during the period. With regard to the bond
portion of the Portfolio, Lord Abbett Bond Debenture Portfolio displayed strong
performance during the period, aiding overall returns.

We made one change to the underlying portfolios in the Strategic Conservative
Growth Portfolio during the period, replacing Pioneer Mid-Cap Value Portfolio
with Neuberger Berman Partners Mid Cap Value Portfolio.

OUTLOOK

The rate of economic growth in the U.S. has slowed in recent quarters. We
believe we are moving through the low point of the cycle and expect growth to
gradually improve in coming quarters. This positive growth is expected to fuel
corporate profits, capital spending, and employment, thus supporting further
economic expansion. Within domestic equities, we favor large-cap stocks based
on relative valuations. As a group, large-caps have shown improved fundamentals
over the past several years which have not been reflected in valuations.
Continued exposure to domestic mid-cap and small-cap stocks, as well as foreign
equities provides additional growth opportunities and portfolio
diversification. The relatively small bond allocation tempers the overall risk
of an otherwise all-equity portfolio. Within fixed-income, relatively
attractive yields are available in investment-grade, short- and
intermediate-maturity bonds. We continue to limit exposure to speculative-grade
bonds.

* Neuberger Berman Partners Mid Cap Value Portfolio was added to the Portfolio
during February 2007. Therefore, it was not held in the Portfolio for the full
six-month period.

+The chart reflects the performance of Class B shares of the Portfolio. This is
currently the only active Class in the Portfolio.

/1/The Wilshire 5000 Equity Index measures the performance of all U.S.
headquartered equity securities with readily available price data. The market
capitalized weighted index is compromised of approximately 82% New York Stock
Exchange, 2% American Stock Exchange and 16% OTC (1995). The Index was created
in 1974 and backdated to 1971, with a base index of December 1980 (base index
equals 1,044.596). Dividends are reinvested on the "ex" dividend date and the
rebalancing of share weights is done on a monthly basis. No attempt has been
made to adjust the market capitalization of the index to take into account
cross holding between corporations. The Index does not include fees or expenses
and is not available for direct investment.

/2/ The blended benchmark is comprised of 20% Lehman Brothers Aggregate Bond
Index, 43% S&P 500(R) Index, 15% S&P 400(R) MidCap Index, 7% S&P 600(R)
SmallCap Index, and 15% MSCI EAFE(R) Index.

The Lehman Brother Aggregate Bond Index represents securities that are U.S.
domestic, taxable, non-convertible and dollar denominated. The Index covers the
investment grade fixed rate bond market with index components for government
and corporate securities, mortgage pass-through securities, and asset-backed
securities. The Index does not include fees or expenses and is not available
for direct investment.

The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen for
market size, liquidity, and industry group representation. It is a market-value
weighted index (stock price times number of shares outstanding), with each
stock's weight in the Index proportionate to its market value. The Index does
not include fees or expenses and is not available for direct investment.

The S&P MidCap 400(R) Index is a capitalization-weighted index which measures
the performance of the mid-range sector of the U.S. Stock market. The Index
does not include fees or expenses and is not available for direct investment.

The S&P SmallCap 600(R) Index is a capitalization-weighted index which measures
the performance of the small-cap range of the U.S. stock market. The Index does
not include fees or expenses and is not available for direct investment.

The Morgan Stanley Capital International Europe, Australasia and Far East Index
("MSCI EAFE(R) Index") is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance excluding the US & Canada. The Index does not include fees or
expenses and is not available for direct investment.

/3/"Cumulative Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of Class B shares is 11/1/06. Index returns are based on an
inception date of 10/31/06.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Strategic Conservative Growth Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class B Shares are offered
by the Portfolio. Class A and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with Gallatin Asset Management, Inc., (the "Adviser") for investment advisory

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES -
CONTINUED


The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing
distribution and shareholder servicing with respect to the Class B and Class E
Shares for such entities' fees or expenses incurred or paid in that regard.

Strategic Conservative Growth Portfolio    $198,525              $--           $198,525


As of December 31, 2006, the components of distributable earnings (accumulated
losses) on a federal income tax basis were as follows:

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

7. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

8. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

9. OTHER MATTERS

exercising management or control; however, investments by the Portfolio within

MARKET OVERVIEW

Continuing the general trend of the past four years, financial markets
progressed markedly during the first half of 2007. Volatility returned to the
markets with episodic appearances over the past six months. Global markets
dropped sharply in February on fears of a slowdown in U.S. economic growth from
a subprime lending meltdown. Despite significant declines, markets recovered
sharply and ended the first quarter on a positive note. The advancement
continued during the second quarter as markets remained resilient and the Dow
and S&P 500 reached all-time highs. Year-to-date through June 30, the S&P
500(R) Index returned 6.9%, the S&P MidCap 400(R) Index returned 11.9%, and the
S&P SmallCap 600(R) Index returned 8.6%. Energy was the best performing sector
across large-cap and mid-cap stocks, while materials dominated in small-caps.
Financials were the biggest laggard across all market capitalizations. Foreign
stocks, as measured by the MSCI EAFE(R) Index, returned 10.7% in light of
continued strong economic growth abroad. Bonds underperformed equities with the
Lehman Brothers Aggregate Bond Index returning 0.98%.

PORTFOLIO OVERVIEW

For the six-month period ended June 30, 2007, the Portfolio (Class B) returned
4.97%, underperforming its blended benchmark which returned 5.41%. Much of the
underperformance was attributed to the Portfolio's mid-cap exposure. Despite
strong absolute returns, Neuberger Berman Mid Cap Value Portfolio* and FI Mid
Cap Opportunities Portfolio lagged the broad S&P MidCap 400(R) Index during the
period. Another area of underperformance was the Portfolio's real estate
holding, Neuberger Berman Real Estate Portfolio, as REIT's sold off sharply
during the latter portion of the six-month period. The Portfolio's fixed-income
portion also detracted, with PIMCO Total Return Portfolio and BlackRock Bond
Income Portfolio lagging the Lehman Aggregate Bond Index during the period.
Sources of strength for the period included the Portfolio's large-cap and
small-cap holdings. Within large-cap, the two growth-oriented portfolios, T.
Rowe Price Large Cap Growth Portfolio and Oppenheimer Capital Appreciation
Portfolio, outperformed the broader S&P 500 Index. Within small-cap, Franklin
Templeton Small Cap Growth Portfolio gained 10.18% during the period,
outperforming the S&P SmallCap 600(R) Index by 1.62%.

We made one change to the underlying portfolios in the Strategic Growth and
Income Portfolio during the period, replacing Pioneer Mid-Cap Value Portfolio
with Neuberger Berman Partners Mid Cap Value Portfolio.

OUTLOOK

The rate of economic growth in the U.S. has slowed in recent quarters. We
believe we are moving through the low point of the cycle and expect growth to
gradually improve in coming quarters. This positive growth is expected to fuel
corporate profits, capital spending, and employment, thus supporting further
economic expansion. Within domestic equities, we favor large-cap stocks based
on relative valuations. As a group, large-caps have shown improved fundamentals
over the past several years which have not been reflected in valuations.
Continued exposure to domestic mid-cap and small-cap stocks, as well as foreign
equities provides additional growth opportunities and portfolio
diversification. Within fixed-income, relatively attractive yields are
available in investment-grade, short- and intermediate-maturity bonds. We
continue to limit exposure to speculative-grade bonds.

+The chart reflects the performance of Class B shares of the Portfolio. This is
currently the only active Class in the Portfolio.

/1/The MSCI Global Capital Markets Index/SM/ is an unmanaged index which
measure the performance of the core capital markets asset classes comprising
global equities and fixed income. It is a market capitalization weighted
composite of the MSCI All Country World Index/SM/ and the MSCI Global Total
Bond Index/SM/. The MSCI All Country World Index/SM/ is an unmanaged free
float-adjusted market capitalization index that is designed to measure equity
market performance in the global developed and emerging markets. The MSCI All
Country World Index includes 49 country indices. The MSCI Global Total Bond
Index is an unmanaged index which measures the capitalization weighted
performance of sovereign, investment grade credit and high yield bond markets
with appropriate adjustments for investability and to eliminate double
counting. The MSCI Global Total Bond Index/SM/ includes the World Sovereign
Debt Index, USD Total Bond Index, Euro Dollar Credit Index, Euro Sterling
Credit Index, Euro Credit Index, Emerging Market Local Sovereign Index and High
Yield Sovereign and Corporate Indices.

/2/The blended benchmark is comprised of 35% Lehman Brothers Aggregate Bond
Index, 30% S&P 500(R) Index, 15% S&P MidCap 400(R) Index, 5% S&P SmallCap
600(R) Index, 10% MSCI EAFE(R) Index, and 5% Dow Jones Wilshire REIT Index.

The Lehman Brothers Aggregate Bond Index represents securities that are U.S.
domestic, taxable, non-convertible and dollar denominated. The Index covers the
investment grade fixed rate bond market, with index components for government
and corporate securities, mortgage pass-through securities, and asset-backed
securities. The Index does not include fees or expenses and is not available
for direct investment.

The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen for
market size, liquidity, and industry group representation. It is a market-
value weighted index (stock price times number of shares outstanding), with
each stock's weight in the Index proportionate to its market value.

The S&P MidCap 400(R) Index is a capitalization-weighted index which measures
the mid-range sector of the U.S. stock market. The Index does not include fees
or expenses and is not available for direct investment.

The S&P SmallCap 600(R) Index is a capitalization-weighted index which measures
the small-cap range of the U.S. stock market. The Index does not include fees
or expenses and is not available for direct investment.

The Morgan Stanley Capital International Europe, Australasia and Far East Index
("MSCI EAFE(R) Index") is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance, excluding the US & Canada. The Index does not include fees or
expenses and is not available for direct investment.

The Dow Jones Wilshire REIT Index measures U.S. publicly traded real estate
investment trusts. The Index does not include fees or expenses and is not
available for direct investment.

/3/"Cumulative Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of Class B shares is 11/1/06. Index returns are based on an
inception date of 10/31/06.

Effective July 1, 2007, Morgan Stanley Capital International, Inc. (MSCI)
discontinued the MSCI Global Capital Markets Index and the Portfolio will use
the Dow Jones Moderate Portfolio Index in future reports to policyholders as
the Portfolio's primary benchmark.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would
be lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)


1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Strategic Growth and Income Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class B Shares are offered
by the Portfolio. Class A and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is

      Strategic Growth and Income Portfolio $106,224     $--      $106,224


As of December 31, 2006, the components of distributable earnings (accumulated

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

7. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

8. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MARKET OVERVIEW

Continuing the general trend of the past four years, financial markets
progressed markedly during the first half of 2007. Volatility returned to the
markets with episodic appearances over the past six months. Global markets
dropped sharply in February on fears of a slowdown in U.S. economic growth from
a subprime lending meltdown. Despite significant declines, markets recovered
sharply and ended the first quarter on a positive note. The advancement
continued during the second quarter as markets remained resilient and the Dow
and S&P 500 reached all-time highs. Year-to-date through June 30, the S&P
500(R) Index returned 6.9%, the S&P MidCap 400(R) Index returned 11.9%, and the
S&P SmallCap 600(R) Index returned 8.6%. Energy was the best performing sector
across large-cap and mid-cap stocks, while materials dominated in small-caps.
Financials were the biggest laggard across all market capitalizations. Foreign
stocks, as measured by the MSCI EAFE(R) Index, returned 10.7% in light of
continued strong economic growth abroad. Bonds underperformed equities with the
Lehman Brothers Aggregate Bond Index returning 0.98%.

PORTFOLIO OVERVIEW

For the six-month period ended June 30, 2007, the Portfolio (Class B) returned
8.27%, underperforming its blended benchmark which returned 8.63%. Most of the
underperformance was attributed to the Portfolio's mid-cap holdings as the
mid-cap value portion of the model, Neuberger Berman Mid Cap Value Portfolio*,
lagged the broad S&P MidCap 400(R) Index. The Portfolio's large-cap segment
also detracted, with Jennison Growth Portfolio and Van Kampen Comstock
Portfolio holding back returns as both lagged the broad S&P 500(R) Index.
Sources of strength for the period included the Portfolio's small-cap and
foreign holdings. Within small-cap, Franklin Templeton Small Cap Growth
Portfolio gained 10.18% during the period, outperforming the S&P SmallCap
600(R) Index. Within the foreign sleeve of the Portfolio, exposure to emerging
market equities had the greatest impact, with MFS(R) Emerging Markets Equity
Portfolio returning 14.58% during the period.

We made one change to the underlying portfolios in the Strategic Growth
Portfolio during the period, replacing Pioneer Mid-Cap Value Portfolio with
Neuberger Berman Partners Mid Cap Value Portfolio.

OUTLOOK

The rate of economic growth in the U.S. has slowed in recent quarters. We
believe we are moving through the low point of the cycle and expect growth to
gradually improve in coming quarters. This positive growth is expected to fuel
corporate profits, capital spending, and employment, thus supporting further
economic expansion. Within domestic equities, we favor large-cap stocks based
on relative valuations. As a group, large-caps have shown improved fundamentals
over the past several years which have not been reflected in valuations.
Continued exposure to domestic mid-cap and small-cap stocks, as well as foreign
equities, provides additional growth opportunities and portfolio
diversification.

*Neuberger Berman Partners Mid Cap Value Portfolio was added to the Portfolio
during February 2007. Therefore, it was not held in the Portfolio for the full
six-month period.

+The chart reflects the performance of Class B shares of the Portfolio. This is
currently the only active Class in the Portfolio.

/1/The Wilshire 5000 Equity Index measures the performance of all U.S.
headquartered equity securities with readily available price data. The market
capitalized weighted index is compromised of approximately 82% New York Stock
Exchange, 2% American Stock Exchange and 16% OTC (1995). The Index was created
in 1974 and backdated to 1971, with a base index of December 1980 (base index
equals 1,044.596). Dividends are reinvested on the "ex" dividend date and the
rebalancing of share weights is done on a monthly basis. No attempt has been
made to adjust the market capitalization of the index to take into account
cross holding between corporations. The Index does not include fees or expenses
and is not available for direct investment.

/2/The blended benchmark is comprised of 55% S&P 500(R) Index, 15% S&P MidCap
400(R) Index, 10% S&P SmallCap 600(R) Index, and 20% MSCI EAFE(R) Index.

The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen for
market size, liquidity, and industry group representation. It is a market-value
weighted index (stock price times number of shares outstanding), with each
stock's weight in the Index proportionate to its market value. The Index does
not include fees or expenses and is not available for direct investment.

The S&P MidCap 400(R) Index is a capitalization-weighted index which measures
the performance of the mid-range sector of the U.S. stock market. The Index
does not include fees or expenses and is not available for direct investment.

The S&P SmallCap 600(R) Index is a capitalization-weighted index which measures
the performance of the small-cap range of the U.S. stock market. The Index does
not include fees or expenses and is not available for direct investment.

The Morgan Stanley Capital International Europe, Australasia and Far East Index
("MSCI EAFE(R) Index") is an unmanaged free float-adjusted market
capitalization index that is designed to measure developed market equity
performance excluding the US & Canada. The Index does not include fees or
expenses and is not available for direct investment.

/3/"Cumulative Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of Class B shares is 11/1/06. Index returns are based on an
inception date of 10/31/06.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Strategic Growth Portfolio, which is
non-diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class B Shares are offered
by the Portfolio. Class A and E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with Gallatin Asset Management, Inc., (the "Adviser") for investment advisory
services in connection with the investment management of the Portfolio.

Subject to the supervision and direction of the Board, the Manager supervises
the Adviser and has full discretion with respect to the retention or renewal of
the advisory agreement. The Manager pays the Adviser a fee based on the
Portfolio's average daily net assets.

Under the terms of the Portfolio's investment advisory agreement, the Portfolio

State Street Bank and Trust Company provides custodian and administration
services to the Trust. Effective April 30, 2007, Metropolitan Life Insurance
Company (MLIC) became the new transfer agent for the Trust. MLIC is an
affiliate of the Manager. MLIC receives no fees for its services to the Trust.

agent to the Trust.

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES -
CONTINUED


If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended December 31,
2006 is shown as investment advisory fee waiver in the Statement of Operations
of the Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing
distribution and shareholder servicing with respect to the Class B and Class E
Shares for such entities' fees or expenses incurred or paid in that regard.

The tax character of distributions paid for the period ended December 31, 2006
was as follows:

   Strategic Growth Portfolio    $121,083              $98           $121,181


As of December 31, 2006, the components of distributable earnings (accumulated
losses) on a federal income tax basis were as follows:



                           Undistributed Undistributed     Net

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

7. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

8. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

9. OTHER MATTERS

exercising management or control; however, investments by the Portfolio within
its principal investment strategies may represent a significant portion of the

T. ROWE PRICE MID-CAP GROWTH PORTFOLIO             FOR THE PERIOD ENDED 6/30/07
MANAGED BY T. ROWE PRICE ASSOCIATES, INC.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------

PERFORMANCE

The Portfolio outperformed the Russell Midcap(R) Growth Index in the six-month
period ended June 30, 2007. Stock selection decisions in the information
technology, financials and consumer discretionary sectors were sources of
outperformance. An underweighting of the materials sector and stock selection
decisions in the industrials and business service sector detracted from
relative returns.

MARKET ENVIRONMENT

Within the mid-cap universe, growth stocks have lagged value stocks for the
trailing 12 months. However, in the most recent quarter growth stocks
significantly outperformed value across the capitalization range. Energy,
materials, and industrials and business service stocks have paced mid-cap
growth returns within the benchmark. On average, stocks in the financials,
consumer staples and consumer discretionary sectors lagged benchmark returns.

PORTFOLIO REVIEW

Outperformance by the portfolio's information technology holdings represents a
significant turnaround, as portfolio exposure to the sector had been a major
detractor in recent reporting periods.

The portfolio's position in aQuantive benefited relative returns when Microsoft
agreed to acquire the digital marketing company at an 85% premium. The deal is
expected to close in the second half of the year. Additionally, shares of
VeriSign, a provider of security software for online transactions, increased
significantly with the resignation of its CEO. The rally in VeriSign shares
marked a turnaround from last summer's panic-driven woes when the stock
weakened under criticism of the company's practices in issuing options. Stock
selection in electronic equipment and instruments and in alternative energy
companies also performed well. Shares of First Solar, a component manufacturer,
have performed well over the last two quarters on strong demand.

Outperformance in financials was driven by stock selection in capital markets
companies and lack of exposure to real estate investment trusts (REITs) where
jittery investor sentiment has hurt performance. In general, financials have
been under pressure as a result of weakness in the sub-prime mortgage market.
Asset manager Eaton Vance continues to benefit from strong net flows, good use
of capital, and solid management.

An underweight in the materials sector detracted from relative results.
Increasing commodity prices and on-going merger and acquisition activity have
fueled growth in the materials sector.

Selections in the industrials and business service sector detracted. Freight
logistics provider UTi Worldwide posted disappointing fourth quarter results
due to a large expense ramp-up in anticipation of accelerated growth. Shares
have rebounded slightly after the firm met street expectations for the first
quarter. Southwest Airlines has performed well relative to other airlines;
however, compared to other industrial and business services companies, results
have been sub par. Most airlines have suffered due to increases in jet-fuel
prices and passenger resistance to higher ticket prices.

OUTLOOK

While our outlook remains generally favorable, we continue to expect that some
of the contradictions in the economy will be resolved as it enters a seventh
year of expansion. In particular, consumers are likely to feel a greater pinch
as the housing sector continues the process of unwinding from its largest
expansion cycle since World War II. We believe the developing environment could
continue to bode well for growth stocks.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the other Classes
because of the difference in expenses paid by policyholders investing in the
different share classes.

/1/The Russell Midcap(R) Growth Index is an unmanaged index which measures the
performance of those Russell Midcap companies with higher price-to-book ratios
and higher forecasted growth values. The stocks are also members of the Russell
1000 Growth Index. The Index does not include fees or expenses and is not
available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A shares is 5/1/01. Inception of the Class B shares
is 2/12/01. Inception of the Class E shares is 10/31/01. Index returns are
based on an inception date of 2/12/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is T. Rowe Price Mid-Cap Growth Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A, B and E Shares are
offered by the Portfolio. Shares of each Class of the Portfolio represent an
equal pro rata interest in the Portfolio and generally give the shareholder the
same voting, dividend, liquidation, and other rights. Investment income,
realized and unrealized capital gains and losses, the common expenses of the
Portfolio and certain Portfolio-level expense reductions, if any, are allocated
on a pro rata basis to each class based on the relative net assets of each
class to the total net assets of the Portfolio. Each class of shares differs in
its respective distribution expenses and certain other class-specific expense
reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                                      12



                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

dividends, interest, and foreign withholding taxes recorded on the Portfolio's
books, and the U.S. dollar equivalent of the amounts actually received or paid.
Net unrealized foreign exchange gains and losses arise from changes in the
value of assets and liabilities other than investments in securities at fiscal
year end, from changes in the exchange rates of foreign currency held, and from
changes in the contract value of forward foreign currency contracts.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a
percentage of the Portfolio's average daily net assets:



                                                 Maximum Expense Ratio

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

Effective February 17, 2005, T. Rowe Price Associates, Inc. ("T. Rowe Price")
has agreed to a voluntary subadvisory fee waiver that applies if (i) assets
under management by T. Rowe Price for the Trust and Metropolitan Series Fund,

subadvises three or more portfolios of the Trust and MSF in the aggregate and
(iii) at least one of those portfolios is a large cap domestic equity
portfolio. The Manager has voluntarily agreed to reduce its advisory fee for T.
Rowe Price Mid-Cap Growth Portfolio by the amount waived (if any) by T. Rowe
Price for the Portfolio pursuant to this voluntary subadvisory fee waiver.

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

THIRD AVENUE SMALL CAP VALUE PORTFOLIO             FOR THE PERIOD ENDED 6/30/07
MANAGED BY THIRD AVENUE MANAGEMENT LLC

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


For the half year ended June 30, 2007, the Third Avenue Small Cap Value
Portfolio ("the Portfolio") appreciated by 6.90% for Class A, compared to
returns of 6.96%, 6.45%, and 3.80% for the S&P 500(R) Index/1/, Russell 2000(R)
Index/2/ and Russell 2000(R) Value Index, respectively. The positive absolute
performance during the period was driven by meaningful appreciation from
various holdings, including Commscope, Inc. (up 91%), Tidewater, Inc. (up 47%),
Agrium, Inc. (up 39%), Fording Canadian Coal Trust (up 63%) and Canfor
Corporation (up 37%). These positive contributions were partially offset by
declines in other holdings, including Lexmark International (down 33%), The St.
Joe Company (down 13%), Skyline Corporation (down 25%), MDC Holdings (down 14%)
and Haverty Furniture Companies (down 20%).

During the first half of the year, the Portfolio acquired thirteen new common
stock positions, increased its position in forty holdings, reduced its position
in five holdings, and eliminated eleven positions. Comments on several of these
changes are provided below.

One position acquired during the period was Bristow Group. Bristow Group is the
largest contractor of helicopter services to the global oil and gas industry. A
majority of Bristow's work comes from offshore production activity, a less
volatile source of revenue than that derived from exploration activities.
Competitive forces in the next two years or so ought to be relatively tame as
demand for helicopter services seems to be outpacing supply, a supply that is
constrained as helicopter manufacturers are fully booked for a number of years.
Bristow Common was purchased at a modest discount to Management's conservative
estimate of Net Asset Value, a value that is likely to grow should the
company's ambitious fleet expansion capitalize on the attractive growth
prospects offered by opportunities in the Middle East and Southeast Asia. A
liquid market for helicopters exists outside the energy industry underpinning
the company's asset values, and lending significant downside protection to this
investment.

During the first half, we also purchased shares in Glatfelter. Founded in 1864,
Glatfelter produces specialty papers and owns a modest tract of timberlands
that it is in the process of monetizing. Specialty papers include paper used in
the production of high quality hardbound books and envelopes as well as other
highly technical customized products. Additionally, the company produces other
specialized items such as tea

bags, coffee filters and metallized products for bottle labels. The company
boasts leading shares of its served markets--markets that have benefited from
consolidation and rationalization of producer capacity--and low cost production
based on its vertically integrated operations. The company's cyclically
depressed current earnings profile ought to improve as recent acquisitions
start to contribute, and as debt reduction occurs over the next 12-24 months.

American Power Conversion Corp. was eliminated as a result of a "resource
conversion" (E.G., selling to a strategic buyer) in the first quarter.
Schneider Electric S.A. completed its acquisition (originally announced during
the fourth quarter of 2006) of American Power Conversion Corp. for $31 per
share in cash. The offer price represented roughly a 30% premium over the
market price at the time of the announcement. This resource conversion produced
a very significant return on our investment.

We also eliminated our position in Comverse Technology, during the first
quarter, following the announcement of an acquisition by Verint (a majority
owned subsidiary of Comverse Technology) at a price that we considered to be
excessive. Our sale decision was also influenced by considerable management
turnover related primarily to options backdating.

During the second quarter, Bridgestone Corporation completed its all cash
acquisition of Bandag, Inc. at $50.75 per share, representing a 13% premium to
the market price of the stock prior to the acquisition announcement, and a
significant premium to the Portfolio's cost basis in Bandag.

We appreciate your continued support and look forward to writing you again in
the future.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B shares
because of the difference in expenses paid by policyholders investing in the
different share class.

/1/The Russell 2000(R) Value Index is an unmanaged index which measures the
performance of those Russell 2000 companies with lower price-to-book ratios and
lower forecasted growth values. The Index does not include fees or expenses and
is not available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A and Class B shares is 5/1/02. Index returns are
based on an inception date of 5/1/02.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Third Avenue Small Cap Value Portfolio,
which is non-diversified. Shares in the Trust are not offered directly to the
general public and are currently available only to separate accounts
established by certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually

received or paid. Net unrealized foreign exchange gains and losses arise from
changes in the value of assets and liabilities other than investments in
securities at fiscal year end, from changes in the exchange rates of foreign
currency held, and from changes in the contract value of forward foreign
currency contracts.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with Third Avenue Management LLC, (the "Adviser") for investment advisory
services in connection with the investment management of the Portfolio.

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The Trust has distribution agreements with MetLife Investors Distribution

result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MANAGED BY TURNER INVESTMENT PARTNERS, INC.

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------


MARKET REVIEW

In a reversal to a trend that has prevailed for most of the decade, the stock
market favored growth stocks in the first six months of 2007; it was powered
generally by the shares of companies with the greatest earnings power. The
Turner Mid-Cap Growth Portfolio, which emphasizes growth stocks, performed
well, up 13.86% for Class A, producing a solid gain that handily outperformed
its benchmark, the Russell Midcap(R) Growth Index, which had a return of 10.97%.

PORTFOLIO REVIEW

Adding the most value to results for the six month period ending June 30, 2007
were financials, consumer-discretionary, and energy, a 44% weighting. In
financials, overweighted positions in IntercontinentalExchange Inc. and
Affiliated Managers Group Inc. contributed to performance. In the consumer
discretionary sector, aQuantive Inc. and Guess? Inc. were strong performers.
National Oilwell Varco and First Solar Inc. had strong absolute and relative
returns in the energy sector. Overall, seven of the Portfolio's ten sector
positions beat their corresponding index sectors.

Subpar returns in the technology and healthcare sectors impaired results the
most. In technology, Isilon Systems Inc., Akamai Technologies and NVIDIA Corp.
were the biggest relative detractors. In healthcare, Sepracor, Inc., Medicis
Pharmaceutical Corp., and Psychiatric Solutions, Inc. were impediments.

In managing the Portfolio, our focus remains on owning stocks that we think
have superior earnings prospects. We currently favor shares of companies in the
Internet, gaming, luxury-retailing, investment-exchange, oilfield services, oil
and gas production, biotechnology, semiconductor, and telecommunications
industries.

OUTLOOK

We continue to anticipate that 2007 will prove a year in which price/earnings
ratios expand--a circumstance that typically bodes well for growth stocks. We
think any multiple expansion (which would be the first since 2003) could help
to offset the decelerating rate of corporate earnings growth. So, although we
think the stock market should be higher at the end of the year than it is now,
a number of risks could confound that outlook: consumer spending, which
accounts for about 70% of the gross domestic product, is softening; petroleum
prices threaten to spike sharply higher; and a large loss in the suddenly
unsteady Chinese stock market could have an adverse impact on the U.S. market.
But we don't assign a high probability to any of those risks. In managing the
Portfolio, our focus remains always on owning stocks that we think have
superior earnings prospects.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B shares
because of the difference in expenses paid by policyholders investing in the
different share class.

/1/The Russell Midcap(R) Growth Index is an unmanaged index which measures the
performance of those Russell Midcap companies with higher price-to-book ratios
and higher forecasted growth values. The stocks are also members of the Russell
1000 Growth index. The Index does not include fees or expenses and is not
available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A and Class B shares is 5/1/04. Index returns are
based on an inception date of 4/30/04.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

account value over the period, multiplied by 181/365 (to reflect the one-half
year period).

                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Turner Mid-Cap Growth Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                          MET INVESTORS SERIES TRUST
                         NOTES TO FINANCIAL STATEMENTS
                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with Turner Investment Partners, Inc., (the "Adviser") for investment advisory
services in connection with the investment management of the Portfolio.

Subject to the supervision and direction of the Board, the Manager supervises
the Adviser and has full discretion with respect to the retention or renewal of
the advisory agreement. The Manager pays the Adviser a fee based on the
Portfolio's average daily net assets.

State Street Bank and Trust Company provides custodian and administration

Company (MLIC) became the new transfer agent for the Trust. MLIC is an
affiliate of the Manager. MLIC receives no fees for its services to the Trust.
Prior to April 30, 2007, State Street Bank and Trust Company served as transfer

The Manager has entered into an expense limitation agreement with the Trust
("Expense Limitation Agreement") in the interest of limiting expenses of the
Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including
amounts payable pursuant to a plan adopted in accordance with Rule 12b-1 under
the 1940 Act are limited to the following respective expense ratios as a
percentage of the Portfolio's average daily net assets:

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

MANAGED BY MORGAN STANLEY INVESTMENT MANAGEMENT, INC. (DBA VAN KAMPEN)

LETTER TO POLICYHOLDERS

- --------------------------------------------------------------------------------

MARKET CONDITIONS

Although stocks generally rose over the six months ended June 30, 2007,
increased volatility tempered the market's gains. Weighing heavily on the
market were concerns about rising inflation and interest rates, which would
likely dampen consumer spending, corporate profits and the boom in corporate
buyouts--some of the chief factors driving the markets in the past few years.
Moreover, a higher interest rate environment would make bonds appear more
attractive than stocks, which would lead investors to rotate out of the stock
market. The weakening U.S. housing market was another source of heightened
anxieties. Lower home values are expected to remove a significant source of
consumer borrowing, home equity, which would trigger a slump in consumer
spending. Furthermore, several hedge funds invested in securities related to
subprime mortgages (loans made to less creditworthy consumers) were nearing
collapse at the end of the reporting period. Despite these overhangs, other
more positive news continued to bolster stock investors' enthusiasm. Wage
growth and steady employment trends helped support consumer spending, fueling a
slight uptick in economic growth from the first quarter to the second quarter
of 2007. Corporate earnings reported for the first quarter were reasonably
strong. But, given the recently more turbulent environment, investors tempered
their expectations for second quarter earnings, which were made available after
the close of this reporting period.

PERFORMANCE ANALYSIS

For the six-month period ended June 30, 2007, the Portfolio's Class A shares
returned 6.11 percent and class B shares returned 6.02 percent. In comparison,
the Portfolio's benchmark, the S&P 500(R) Index, returned 6.96 percent for the
same period.

The Portfolio's underperformance relative to the S&P 500(R) Index was primarily
driven by the Portfolio's lack of exposure to energy stocks. By our measures,
these stocks are overpriced relative to our assessment of fair value. Our stock
selection in the financials sector was also a detractor from relative
performance, as the Portfolio's diversified financial holdings did not perform
as well as those represented in the S&P 500(R) Index.

However, the Portfolio performed well relative to the S&P 500(R) Index in other
areas. The Portfolio's holdings in the health care sector, which are almost
entirely pharmaceutical stocks, were a source of strength for relative returns.
The pharmaceutical industry began to see a turnaround after waning investor
sentiment kept pharmaceutical companies' stock prices depressed for the past
several years. In the consumer staples sector, the Portfolio held a food
company and a diversified consumer goods company that contributed positively to
relative performance.

MANAGEMENT STRATEGY

Investors have continued to favor cyclical stocks (those stocks whose
performance is highly correlated to the economic cycle)--and in particular,
energy stocks--for what seems like a protracted period. However, the expensive
valuations in these areas of the market indicate to us that investors have
continued to overlook the considerable downside of these stocks in a
decelerating economic environment. Rather than chase such short-term,
unsustainable performance, we continue to seek stocks with reasonable
valuations relative to our assessment of fair value. As a result, all sector
weights are built from the bottom up, driven by the valuation opportunities
presented by individual companies and not by economic or market forecasts. On
that basis, the Portfolio continued to have greater exposure to those companies
whose earnings growth does not depend on the economic cycle, including notable
weights in health care, consumer discretionary and consumer staples stocks. In
contrast, the lack of compelling opportunities in cyclical stocks has resulted
in the Portfolio's very modest exposure to the industrials sector and its zero
weighting in energy stocks. Additionally, we recently trimmed selected
telecommunication services holdings based on company-specific fundamental and
valuation factors.

There is no guarantee that the sectors mentioned will continue to perform well
or be held by the portfolio in the future.

Data as of 6/30/07 and is subject to change at any time. The commentary is
provided for informational purposes only and should not be deemed a
recommendation to buy or sell securities in the sectors mentioned above.

+The chart reflects the performance of Class A shares of the Portfolio. The
performance of Class A shares will differ from that of the Class B shares
because of the difference in expenses paid by policyholders investing in the
different share class.

/1/The S&P 500(R) Index is an unmanaged index consisting of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market-value weighted index (stock price times number of shares outstanding),
with each stock's weight in the Index proportionate to its market value. The
Index does not include fees or expenses and is not available for direct
investment.

/2/The Russell 1000(R) Value Index is an unmanaged index which measures the
performance of those Russell 1000(R) Index companies with lower price-to-book
ratios and lower forecasted growth values. The Index does not include fees and
expenses and is not available for direct investment.

/3/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/4/Inception of Class A and Class B shares is 5/2/05. Index returns are based
on an inception date of 4/30/05.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

year period).

Portfolio included in this report is Van Kampen Comstock Portfolio, which is
diversified. Shares in the Trust are not offered directly to the general public
and are currently available only to separate accounts established by certain
affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Portfolio segregates assets having an aggregate value at least equal to the
amount of the when issued or delayed delivery purchase commitments until
payment is made.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

3. INVESTMENT MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust is managed by Met Investors Advisory, LLC which is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Manager is subject to the supervision and direction of the
Board and has overall responsibility for the general management and
administration of the Trust. The Manager has entered into an advisory agreement
with Morgan Stanley Investment Management, Inc., (dba Van Kampen), (the
"Adviser") for investment advisory services in connection with the investment
management of the Portfolio.

Subject to the supervision and direction of the Board, the Manager supervises
the Adviser and has full discretion with respect to the retention or renewal of
the advisory agreement. The Manager pays the Adviser a fee based on the

Portfolio of the Trust. The Expense Limitation Agreement shall continue in
effect with respect to the Portfolio until April 30, 2008. Pursuant to that
Expense Limitation Agreement, the Manager has agreed to waive or limit its fees
and to assume other expenses so that the total annual operating expenses of the
Portfolio other than interest, taxes, brokerage commissions, other expenditures
which are capitalized in accordance with accounting principles generally
accepted in the United States of America, other extraordinary expenses not
incurred in the ordinary course of the Portfolio's business, but including

If in any year in which the Management Agreement is still in effect, the
estimated aggregate Portfolio Operating Expenses of the Portfolio for the
fiscal year are less than the Maximum Expense Ratio for that year, subject to
approval by the Trust's Board, the Manager shall be entitled to reimbursement
by the Portfolio to the extent that the charge does not cause the expenses in
such subsequent year to exceed the Maximum Expense Ratio as stated above. The
Portfolio is not obligated to repay any expense paid by the Manager more than
five years after the end of the fiscal year in which such expense was incurred.

The amount waived and expenses reimbursed for the period ended June 30, 2007 is
shown as investment advisory fee waiver in the Statement of Operations of the
Portfolio.

The Trust has distribution agreements with MetLife Investors Distribution
Company ("MIDC" or the "Distributor") in which MIDC serves as the Distributor
for the Trust's Class A, Class B and Class E shares. MIDC is a wholly-owned
subsidiary of MetLife Investors Group, Inc. which is a wholly-owned subsidiary
of MetLife, Inc. The Class B and Class E Distribution Plans provide that the
Trust, on behalf of the Portfolio, may pay annually up to 0.50% and 0.25%
respectively of the average net assets of the Portfolio attributable to its
Class B and Class E shares in respect to activities primarily intended to
result in the sale of Class B and Class E Shares. However, under Class B and
Class E Distribution Agreements, payments to the Distributor for activities
pursuant to the Class B Distribution Plan and Class E Distribution Plan are
currently limited to payments at an annual rate equal to 0.25% and 0.15% of
average daily net assets of the Portfolio attributable to its Class B and Class
E Shares, respectively.

Under terms of the Class B and Class E Distribution Plans and Distribution
Agreements, the Portfolio is authorized to make payments monthly to the
distributor that may be used to pay or reimburse entities providing
distribution and shareholder servicing with respect to the Class B and Class E
Shares for such entities' fees or expenses incurred or paid in that regard.

The difference between book basis and tax basis is attributable primarily to
the tax deferral of losses on wash sales.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157) was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Portfolio's financial statement disclosures.

LETTER TO POLICYHOLDERS

MARKET CONDITIONS

Although the U.S. equity market advanced in the six months ended June 30, 2007,
domestic economic growth slowed significantly compared to recent years. Gross
domestic product (GDP) reported in at 0.7 percent for the first quarter, which
was substantially lower than in prior periods. Interest rates rose during the
period, creating fears about the possibility of investors rotating out of the
stock market in favor of attractive yields on fixed income instruments.
Moreover, the ongoing deterioration of the sub-prime mortgage market (which
makes loans to less creditworthy borrowers) and its impact on the declining
housing and construction sectors created additional distress for investors.
These anxieties were further exacerbated in June when news broke that Bear
Stearns was offering more than $3 billion in financing to bail out two of its
troubled hedge funds, which invest primarily in mortgage-related securities.
However, despite these worrisome events, investors still retained their
enthusiasm for equities, as positive economic data on the wage growth and
employment fronts reported in the latter weeks of the period supported the
market's momentum. Additionally, relatively strong corporate profits reports
for the first quarter and continued frenetic merger and acquisition (M&A)
activity helped to sustain positive investor sentiment through the end of the
reporting period.

PERFORMANCE ANALYSIS

For the period from January 1, 2007 through June 30, 2007, the Portfolio's A
shares returned 13.15% and B shares returned 12.90%. In comparison, the
Portfolio's benchmark, the Russell Midcap(R) Growth Index, returned 10.97% for
the same period.

Many sectors provided strong positive returns for the Portfolio relative to the
Russell Midcap Growth Index for this period. Within the technology sector,
stock selection in computer software services had the most favorable impact on
overall performance, and an sector underweight also helped. The Portfolio's
holding of a wireless company in the utilities sector significantly added to
relative returns. In the heath care sector, both stock selection and an
underweight allocation were advantageous to performance. In particular, the
Portfolio's investment in medical and dental instruments and supplies and in
health care services turned out to be quite beneficial.

In contrast, the sectors that had the largest negative influence on the
Portfolio's return relative to the Russell Midcap(R) Growth Index were the
other energy, materials and processing, and the multi-industry sectors. In the
other energy sector, an avoidance of oil well equipment companies was a key
detractor to performance. Additionally, an underweight position in the
materials and processing sector diminished the Portfolio's relative returns. In
the multi-industry sector (which includes conglomerates), both stock selection
and an underweight allocation also hindered performance.

MANAGEMENT STRATEGY

We use intensive fundamental research to seek high-quality growth companies.
Our investment discipline favors companies that have sustainable competitive
advantages, business visibility, rising return on invested capital, free cash
flow and a favorable risk/reward profile. Because we emphasize secular growth,
short-term market events are not as meaningful in the stock selection process.

At the end of the period, consumer discretionary represented the largest sector
weight and overweight in the Portfolio, followed by the financial services and
health care sectors. Both the financial services and health care sectors were
underweight versus the Russell Midcap(R) Growth Index.

+The chart reflects the performance of Class B shares of the Portfolio. The
performance of Class B shares will differ from that of the Class A shares
because of the difference in expenses paid by policyholders investing in the
different share class.

/1/The Russell Midcap(R) Growth Index is an unmanaged index which measures the
performance of those Russell Midcap companies with higher price-to-book ratios
and higher forecasted growth values. The stocks are also members of the Russell
1000(R) Growth index. The Index does not include fees or expenses and is not
available for direct investment.

/2/"Average Annual Return" is calculated including reinvestment of all income
dividends and capital gain distributions.

/3/Inception of the Class A shares is 5/1/01. Inception of the Class B shares
is 2/12/01. Index returns are based on an inception date of 2/12/01.

Past performance does not guarantee future results. The investment return and
principal value of an investment in the Portfolio will fluctuate, so that
shares, on any given day or when redeemed, may be worth more or less than their
original cost. Performance numbers are net of all Portfolio expenses but do not
include any insurance, sales, or administration charges of variable annuity or
life insurance contracts. If these charges were included, the returns would be
lower.

MET INVESTORS SERIES TRUST
UNDERSTANDING YOUR PORTFOLIO'S EXPENSES

SHAREHOLDER EXPENSE EXAMPLE

As a mutual fund shareholder you may incur two types of costs: (1) TRANSACTION
COSTS, including sales charges (loads) on purchase payments and redemption fees
and (2) ONGOING COSTS, including management fees, distribution (12b-1) fees,
shareholder services fees and other Portfolio expenses. For Met Investors
Series Trust sales charges and redemption fees do not apply and Class A does
not charge a distribution (12b-1) fee. Costs are described in more detail in
the Portfolio's prospectus. The examples below are intended to help you
understand your ongoing costs of investing in the Portfolio and help you
compare these with the ongoing costs of investing in other mutual funds.

ACTUAL EXPENSES

The first line in the table for each Class of shares shows the ACTUAL account
values and ACTUAL Portfolio expenses you would have paid on a $1,000 investment
in the Portfolio from January 1, 2007 through June 30, 2007. It also shows how
much a $1,000 investment would be worth at the close of the period, assuming
ACTUAL Portfolio returns and expenses. To estimate the expenses you paid over
the period, simply divide your account by $1,000 (for example $8,600 account
value divided by $1,000 = 8.6) and multiply the result by the number in the
"Expenses Paid During Period" column as shown below for your Portfolio and
Class.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual
expense ratio and an ASSUMED rate of return of 5% per year before expenses,
which is not the Portfolio's actual return. Thus, you should NOT use the
hypothetical account values and expenses to estimate the actual ending account
balance or your expenses for the period. Rather, these figures are provided to
enable you to compare the ongoing costs of investing in the Portfolio and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds. Please note
that the expenses shown in the table are meant to highlight your ongoing costs
only. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative TOTAL costs of owning
different funds. In addition, if these transaction costs were included, your
costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your
ongoing cost only. Therefore, the second line of the table is useful in the
comparing ongoing cost only, and will not help you determine the relative TOTAL
costs of owning different funds.

1. ORGANIZATION

Met Investors Series Trust (the "Trust") is registered as an open-end
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust currently offers forty-three portfolios
("Portfolios", collectively; "Portfolio", individually), each of which operates
as a distinct investment vehicle of the Trust. As of June 30, 2007, the
Portfolio included in this report is Van Kampen Mid-Cap Growth Portfolio, which
is diversified. Shares in the Trust are not offered directly to the general
public and are currently available only to separate accounts established by
certain affiliated life insurance companies.

The Trust currently offers three classes of shares: Class A and B Shares are
offered by the Portfolio. Class E Shares are not currently offered by the
Portfolio included in this report. Shares of each Class of the Portfolio
represent an equal pro rata interest in the Portfolio and generally give the
shareholder the same voting, dividend, liquidation, and other rights.
Investment income, realized and unrealized capital gains and losses, the common
expenses of the Portfolio and certain Portfolio-level expense reductions, if
any, are allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the Portfolio. Each class of
shares differs in its respective distribution expenses and certain other
class-specific expense reductions.

2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities at the date of the financial statements and the
reported amounts of income and expenses during the reporting period. Actual
results could differ from these estimates.

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements.

A. SECURITY VALUATION - Portfolio securities for which the primary market is on
a domestic or foreign exchange (except the NASDAQ) will be valued at the last
sale price on the day of valuation or, if there was no sale that day, at the
last reported bid price, using prices as of the close of trading. Portfolio
securities traded over-the-counter and quoted on NASDAQ are valued at the
NASDAQ Official Closing Price ("NOCP"). The NOCP is a "normalized" price. At
4:00 pm EST the NOCP is calculated as follows: (i) if the last traded price of
a listed security reported by a NASDAQ member falls within the current best bid
and ask price, then the NOCP will be the last traded price; (ii) if the last
traded price falls outside of that range, however, the NOCP will be the last
bid price (if higher) or the last ask price (if lower). Portfolio securities
not quoted on NASDAQ that are actively traded in the over-the-counter market,
including listed securities for which the primary market is believed to be
over-the-counter, will be valued at the most recently quoted bid price provided
by the principal market makers. If market values are not readily available, or
if available market quotations are not reliable, securities are priced at their
fair value as determined by the Valuation Committee of the Trust's Board of
Trustees using procedures approved by the Board of Trustees (the "Board"). The
Portfolio may use fair value pricing if the value of a security has been
materially affected by events occurring before the Portfolio's calculation of
NAV but after the close of the primary markets on which the security is traded.
The Portfolio may also use fair value pricing if reliable market quotations are
unavailable due to infrequent trading or if trading in a particular security
was halted during the day and did not resume prior to the Portfolio's
calculation of NAV. Such fair value may be determined by utilizing information
furnished by a pricing service which determines valuations for normal,
institutional-size trading units of such securities using methods based on
market transactions for comparable securities and various relationships between
securities which are generally recognized by institutional traders.

Debt securities are valued at the mean between the bid and asked prices
provided by an independent pricing service that are based on transactions in
debt obligations, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost, which approximates market value. The Portfolio may hold
securities traded in foreign markets. Foreign securities traded outside the
United States will be valued daily at their fair value according to procedures
decided upon in good faith by the Trust's Board. All securities and other
assets of the Portfolio initially expressed in foreign currencies will be
converted to U.S. dollar values at the mean of the bid and offer prices of such
currencies against U.S. dollars quoted as designated on the Price Source
Authorization Agreement between the Trust and its custodian on a valuation date
by any recognized dealer.

The Trust is managed by Met Investors Advisory, LLC (the "Manager"), a
wholly-owned subsidiary of MetLife Investors Group, Inc., which is a
wholly-owned subsidiary of MetLife, Inc. The Manager may, from time to time,
under the general supervision of the Board or the Valuation Committee, utilize
the services of one or more pricing services available in valuing the assets of
the Trust. The Manager will continuously monitor the performance of these
services. The Portfolio has retained a third party pricing service to
automatically fair value each of its investments that is traded principally on
a foreign exchange or market, subject to adjustment by the Valuation Committee
of the Trust's Board of Trustees. The Valuation Committee will regularly
monitor and review the services provided by the pricing service to the
Portfolios and periodically report to the Board on the pricing services'
performance.

Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued daily at forward foreign
currency exchange rates. Investments in mutual funds are valued at the daily
net asset value of the mutual fund.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.
The Portfolio may purchase and sell securities on a "when issued" or "delayed
delivery" basis, with settlement to occur at a later date.

                           JUNE 30, 2007 (UNAUDITED)

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

The value of the security so purchased is subject to market fluctuations during
this period. The Portfolio segregates assets having an aggregate value at least
equal to the amount of the when issued or delayed delivery purchase commitments
until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Interest income, adjusted for amortization
of premium and accretion of discount, is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date. Foreign dividend income is
recorded on the ex-dividend date or as soon as practical after the Portfolio
has determined the existence of a dividend declaration after exercising
reasonable due diligence. Foreign income and foreign capital gains on some
foreign securities may be subject to foreign withholding taxes, which are
accrued as applicable.

D. FEDERAL INCOME TAXES - It is the Portfolio's policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of
1986, as amended (the "Code"), applicable to regulated investment companies.
Accordingly, the Portfolio intends to distribute substantially all of its
taxable income and net realized gains on investments, if any, to shareholders
each year. Therefore, no federal income tax provision is required in the
Portfolio's financial statements. It is also the Portfolio's policy to comply
with the diversification requirements of the Code so that variable annuity and
variable life contracts investing in a portfolio will not fail to qualify as
annuity and life insurance contracts for tax purposes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. As a result,
distributions from net investment income and net realized capital gains may
differ from their ultimate characterization for federal income tax purposes due
to timing differences.

The Portfolio utilizes the provisions of the federal income tax laws that
provide for the carryforward of capital losses for eight years, offsetting such
losses against any future net realized capital gains. At December 31, 2006, the
accumulated capital loss carryforwards and expiration dates by the Portfolio
were as follows:



                                                 Expiring   Expiring   Expiring

Van Kampen Mid-Cap Growth Portfolio $10,804,540  $564,339  $4,499,968 $5,740,233


Van Kampen Mid-Cap Growth Portfolio (formerly, Lord Abbett Growth Opportunities
Portfolio) acquired losses of $13,507,053 in the merger with Lord Abbett
Developing Growth Portfolio on April 28th 2003 which are subject to an annual
limitation of $771,861.

E. DISTRIBUTION OF INCOME AND GAINS - The Portfolio intends to distribute
substantially all of its net investment income and net realized capital gains,
if any, annually.

F. SECURITIES LENDING - The Portfolio may lend its securities to certain
qualified brokers who borrow securities in order to complete certain
transactions. By lending its investment securities, the Portfolio attempts to
increase its net investment income through the receipt of interest on the loan.
Any gain or loss in the market price of the securities loaned that might occur
and any interest earned or dividends declared during the term of the loan would
accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.

Upon entering into a securities lending transaction, the Portfolio receives
cash or other securities as collateral in an amount equal to or exceeding 102%
of the current market value of the loaned securities. Any cash received as
collateral is generally invested by State Street Bank and Trust Company ("State
Street"), acting in its capacity as securities lending agent (the "Agent"), in
the State Street Navigator Securities Lending Prime Portfolio which is a money
market fund registered under the 1940 Act. A portion of the dividends received
on the collateral is rebated to the borrower of the securities and the
remainder is split between the Agent and the Portfolio. On loans collateralized
by cash, the cash collateral is invested in a money market fund or short term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers and the remainder is allocated between the fund
and the lending agent. On loans collateralized by U.S. Treasuries, a fee is
received from the Borrower and is allocated between the fund and the lending
agent.

G. REPURCHASE AGREEMENTS - The Portfolio may enter into repurchase agreements
with selected commercial banks and broker-dealers, under which the Portfolio
acquires securities as collateral and agrees to resell the securities at an
agreed upon time and at an agreed upon price. The Portfolio accrues interest
for the difference between the amount it pays for the securities and the amount
it receives upon resale. At the time the Portfolio enters into a repurchase
agreement, the value of the collateral securities including accrued interest
will be equal to or exceed the value of the repurchase agreement and, for
repurchase agreements that mature in more than one day, the seller will agree
that the value of the collateral securities including accrued interest will
continue to be at least equal to the value of the repurchase agreement.

H. DIRECTED BROKERAGE AGREEMENT - The Trust has entered into a directed
brokerage arrangement with State Street Global Markets ("SSGM"). Under this
arrangement, the Portfolio directs certain trades to SSGM in return for a
recapture credit. SSGM issues a cash rebate to the Portfolio. Amounts paid to
each Portfolio are shown separately as an expense reduction on the Statement of
Operations of the Portfolio.

2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED


I. FOREIGN CURRENCY TRANSLATION - The books and records of the Portfolio are
maintained in U.S. dollars. Foreign currencies, investments and other assets
and liabilities are translated into U.S. dollars on a daily basis using
prevailing exchange rates. Purchases and sales of securities are translated at
the rates of exchange prevailing when such securities were acquired or sold.
Income is translated at rates of exchange prevailing when interest is accrued
or dividends are recorded.

The Portfolio does not isolate that portion of operations resulting from
changes in foreign exchange rates on investments from the fluctuations arising
from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, sales of foreign currencies, currency gains
or losses realized between the trade and settlement dates on securities
transactions, and the difference between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Portfolio's books, and the U.S.
dollar equivalent of the amounts actually received or paid. Net unrealized
foreign exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, from
changes in the exchange rates of foreign currency held, and from changes in the
contract value of forward foreign currency contracts.

8. CONTRACTUAL OBLIGATIONS

The Trust has a variety of indemnification obligations under contracts with its
service providers. The Trust's maximum exposure under these arrangements is
unknown. However, the Trust has not had prior claims or losses pursuant to
these contracts and expects the risk of loss to be remote.

9. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Portfolio's tax returns to determine whether the tax positions
are "more-likely-than-not" of being sustained by the applicable tax authority.
Tax positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Management has
evaluated the implication of FIN 48 and has determined that there is no impact
to the Portfolio's financial statements.
