DEAR SHAREHOLDER,
Despite sharply rising oil prices, threats of terrorism, geopolitical concerns
and uncertainties surrounding the presidential election, the U.S. economy
continued to expand during the reporting period. Following a robust 4.5% gain in
the first quarter of 2004, gross domestic product ("GDP")(i) growth was 3.3% in
the second quarter of the year. This decline was largely attributed to higher
energy prices. However, third quarter 2004 GDP growth rose a strong 4.0%. While
fourth quarter GDP figures have not yet been released, continued growth is
expected.
Turning to the financial markets, stocks in both the U.S. and abroad rallied
sharply during the fourth quarter of 2004, helping to produce solid gains for
the year. With the uncertainty of the presidential election behind them, coupled
with falling oil prices, investors were drawn to the equity markets. The overall
bond market also generated positive returns during the fiscal year. This was
surprising to many, given the economic expansion and five interest rate hikes by
the Federal Reserve Board ("Fed").(ii) At the end of the fund's reporting
period, at their February meeting, the Fed once again raised the target rate by
0.25% to 2.50%.
Within this environment, the portfolios performed as follows:

INFORMATION ABOUT YOUR FUND

As you may be aware, several issues in the mutual fund and variable product
industry have recently come under the scrutiny of federal and state regulators.
Travelers Life & Annuity and some of its affiliates have received requests for
information from various government regulators regarding market timing, late
trading, fees, revenue sharing, producer compensation and other mutual fund and
variable product issues in connection with various investigations. The funds
have been informed that Traveler's Life & Annuity and its affiliates are
responding to those information requests, but are not in a position to predict
the outcome of these requests and investigations.

As previously disclosed by Citigroup, the Staff of the Securities and Exchange
Commission ("SEC") has notified Citigroup Asset Management ("CAM") and Citicorp
Trust Bank ("CTB"), an affiliate of CAM, that the Staff is considering
recommending a civil injunctive action and/or an administrative proceeding
against CAM, CTB, the former CEO of CAM, two former employees and a current
employee of CAM, relating to the creation, operation and fees of an internal
transfer agent unit that serves various CAM-managed funds. Citigroup is
cooperating with the SEC and will seek to resolve this matter in discussion with
the SEC Staff. Although there can be no assurance, Citigroup does not believe
that this matter will have a material adverse effect on the funds. For further
information, please see the "Additional Information" note in the Notes to the
Financial Statements included in this report.

As always, thank you for your confidence in our stewardship of your assets. We
look forward to helping you continue to meet your financial goals.

Sincerely,

/s/ R. Jay Gerken

                                MANAGER OVERVIEW

CONVERTIBLE SECURITIES PORTFOLIO

SPECIAL SHAREHOLDER NOTICE

Effective November 1, 2004, Robert Simmons replaced David A. Tyson as Portfolio
Manager of the Convertible Securities Portfolio.

PERFORMANCE UPDATE(1)

For the twelve months ended December 31, 2004, the Convertible Securities
Portfolio returned 6.29%. In comparison, the portfolio's unmanaged benchmark,
the Merrill Lynch Investment Grade Convertible Bond Index(i), returned 4.69% and
the Lipper Variable Specialty/Miscellaneous Funds Category Average(2) was 7.82%
for the same period.

MARKET/ECONOMIC OVERVIEW

For the year as a whole, convertibles generated solid investment results with
investors, driving the market higher during the fourth quarter. This reversed a
negative trend over the prior two quarters, as economic data was mixed and
interest rates rose. While the convertibles market participated in the year's
late rally, it underperformed the overall stock market, as measured by the S&P
500 Index(ii) which returned 10.87% during this period, and for the entire year.

CONTRIBUTORS TO PERFORMANCE

The portfolio's bias towards investment grade companies served to hold back its
performance during the fiscal year, as speculative grade issues returned roughly
two-and-a-half times as much as investment grade convertibles. However, the
portfolio did benefit from the rise in equity valuations during 2004, as well as
significant spread tightening in the corporate markets.

TYCO INTERNATIONAL GROUP, S.A. was the portfolio's top-performing convertible
security during the fiscal year. This global diversified manufacturing and
service company benefited as the economic recovery gained momentum in 2004. Tyco
also experienced many positive developments during the year, including rating
agency upgrades, as well as significant balance sheet, revenue, earnings, and
cash flow improvement. These factors helped the convertible to return 25.1% in
2004. Examples of other fund holdings that were strong performers were FOUR
SEASONS HOTELS INC., ANIXTER INTERNATIONAL INC., TRIBUNE CO., and ROYAL
CARIBBEAN CRUISES LTD.

The worst performing sectors in the index during the reporting period were in
the transportation and consumer staples sectors. We had no transportation
exposure in the portfolio and were significantly underweighted in consumer
staples versus the overall convertible bond universe. Our worst performing
convertible during the fiscal year was issued by GENERAL MOTORS CORP. This
convertible security was pressured as the company lost market share, had its
ratings lowered by credit agencies, and seemed to become "addicted" to sales
incentives, which significantly hurt the firm's profitability. Investors also
became increasingly concerned that the company would soon see its credit ratings
lowered to below investment grade, or "junk" status, as a result of its high
legacy costs (i.e., pensions) relative to its foreign competitors.

Thank you for your investment in the Convertible Securities Portfolio. As ever,
we appreciate that you have chosen us to manage your assets and we remain
focused on achieving the fund's investment goals.

Sincerely,

/s/ Robert Simmons

                                MANAGER OVERVIEW

MFS MID CAP GROWTH PORTFOLIO

PERFORMANCE UPDATE(1)

For the twelve months ended December 31, 2004, the MFS Mid Cap Growth Portfolio
returned 14.10%. The portfolio underperformed its unmanaged benchmark, the
Russell MidCap Growth Index(i), and the Russell 2000 Index(ii), a secondary
benchmark, which returned 15.48% and 18.33%, respectively, for the same period.
The Lipper Variable Mid-Cap Growth Funds Category Average was 14.75% for the
same period.

MARKET/ECONOMIC OVERVIEW

For stock investors, 2004 was a bumpy ride with a smooth finish. In the end,
improving fundamental factors, such as corporate spending and earnings growth,
triumphed and drove equity markets to solid gains for the year. During the
12-month reporting period, investors endured skyrocketing oil prices, rising
short-term interest rates, a volatile and retreating U.S. dollar, record budget
and trade deficits, and war in Iraq. For some time it seemed these factors would
lead to flat or negative annual performance for many investments. But by the
last quarter of 2004, oil prices retreated, investors seemed to adopt a less
negative view of other broad economic issues and markets appeared to recognize
that both corporate profits and economic growth were up solidly, if not
spectacularly, for the year. We believed that as the year came to a close, the
global economy was still in the midst of a sustainable broad-based recovery.

CONTRIBUTORS TO PERFORMANCE

During the fiscal year, the fund's holdings in the healthcare, utilities and
communications, and special products and services sectors generated the
strongest relative returns. Conversely, its leisure, consumer staples and
industrial goods and services holdings detracted from relative results.

In the healthcare sector, the fund's holding in medical testing company CYTYC
CORP. was one of its strongest relative performers. Medical device firm C.R.
BARD, INC. was also a top contributor to results. In the telecommunication
services sector, an overweight position and strong stock selection both aided
relative results. The strongest performers in this sector were cellular tower
operators AMERICAN TOWER CORP., CLASS A SHARES and SPECTRASITE, INC. Stock
selection in the industrial sector boosted returns, thanks in part to the fund's
holding in Internet job search firm MONSTER WORLDWIDE, INC. Strong relative
contributors in other sectors included computer security firm MCAFEE, INC.,
vacation company ROYAL CARIBBEAN CRUISES LTD., multimedia software developer
COMVERSE TECHNOLOGY, INC. and semiconductor firm MARVELL TECHNOLOGY GROUP LTD.

Conversely, in the consumer discretionary sector, stock selection detracted from
relative performance. In particular, the fund's positions in CITADEL
BROADCASTING CO. and radio conglomerate WESTWOOD ONE, INC. were the largest
detractors from results. Stock selection in the consumer staples sector was also
detrimental to returns. The largest detractor in the sector was Canadian frozen
dessert purveyor COOLBRANDS INTERNATIONAL INC., whose stock fell sharply during
the period. As of period-end, Coolbrands was no longer held in the portfolio. In
the industrials sector, being relatively underweighted and, to some extent,
negative stock selection held back relative returns. Other stocks that hurt
relative results included post-secondary education company CORINTHIAN COLLEGES
INC., semiconductor company PMC-SIERRA, INC., Linux operating system provider
RED HAT, INC., and jewelry retailer TIFFANY & CO. Corinthian Colleges was
subsequently eliminated from the portfolio.

(1)  The fund is an underlying investment option of various variable annuity and
     variable life products. The fund's performance returns do not reflect the
     deduction of sales charges and expenses imposed in connection with
     investing in variable annuity and variable life contracts such as
     administrative fees, account charges and surrender charges which, if
     reflected, would reduce the performance of the fund. PAST PERFORMANCE IS NO
     GUARANTEE OF FUTURE RESULTS.

(2)  Lipper, Inc. is a major independent mutual-fund tracking organization.
     Returns are based on the 12-month period ended December 31, 2004, including
     the reinvestment of dividends and capital gains, if any, calculated among
     the 127 funds in the fund's Lipper category, and excluding sales charges.
                                                                               7

MERRILL LYNCH LARGE CAP CORE PORTFOLIO

PERFORMANCE UPDATE(1)

For the twelve months ended December 31, 2004, the Merrill Lynch Large Cap Core
Portfolio returned 15.89%. The portfolio outperformed its unmanaged benchmark,
the Russell 1000 Index(i), which returned 11.40% for the same period. It also
outperformed the Lipper Variable Large-Cap Core Funds Category Average(2), which
was 8.59%.

MARKET/ECONOMIC OVERVIEW

Thanks to a late year rally, prompted by the lifting of the uncertainty
surrounding the presidential election and falling oil prices, U.S. equities
produced solid results in 2004. Virtually all of the market's gains for the year
occurred in the fourth quarter.

CONTRIBUTORS TO PERFORMANCE

The portfolio's outperformance during the year came from positive stock
selection in the healthcare (especially managed care), consumer discretionary,
utilities, and materials (especially steel) sectors. From an individual stock
perspective, the largest positive contributors to results included TXU CORP.,
AUTODESK, INC., UNITED STATES STEEL CORP., SPRINT CORP., CUMMINS INC., VALERO
ENERGY CORP., MANDALAY RESORT GROUP, and PACIFICARE HEALTH SYSTEMS, INC. An
underweight position versus the benchmark in INTEL CORP. also enhanced relative
results, as its shares were weak during the year. This positive performance was
partially offset by declines in fund holdings: FOUNDRY NETWORKS INC., ATMEL
CORP., CYPRESS SEMICONDUCTOR CORP. and AMKOR TECHNOLOGY INC., as well as being
underweighted in IMCLONE SYSTEMS INC.

During the year, we increased the fund's weighting in the energy, industrials
and utilities sectors. Our largest purchases during the year were ADVANCED MICRO
DEVICES, INC., METLIFE, INC., JOHNSON & JOHNSON, and CHEVRONTEXACO CORP.
Conversely, our largest sales included LEHMAN BROTHERS HOLDINGS INC., ALTRIA
GROUP INC., CISCO SYSTEMS, INC., and QUALCOMM INC.

In managing the portfolio, we continue to emphasize a pro-cyclical approach to
the economy believing that, for now, economic and earnings growth will be
reasonably strong. Accordingly, the portfolio's largest overweighted sectors
include information technology, consumer discretionary, energy and materials.
Our largest underweight positions are in telecommunications, consumer staples,
and financial services.

Thank you for your investment in the Merrill Lynch Large Cap Core Portfolio. As
ever, we appreciate that you have chosen us to manage your assets and we remain
focused on achieving the fund's investment goals.

Sincerely,

Assumes reinvestment of dividends and capital gains, if any, at net asset value.
All figures represent past performance and are not a guarantee of future
results. Investment return and principal value of an investment will fluctuate
so that an investor's shares, when redeemed, may be worth more than or less than
their original cost. Total returns do not reflect expenses associated with the
separate account such as administrative fees, account charges and surrender
charges, which, if reflected, would reduce the total returns. Performance
figures may reflect voluntary fee waivers and/or expense reimbursements. In the
absence of voluntary fee waivers and/or expense reimbursements, the total return
would have been lower.

 FUND EXPENSES (UNAUDITED)

     EXAMPLE

     As a shareholder of the Fund, you may incur two types of costs: (1)
transaction costs, including front-end and back-end sales charges (loads) on
purchase payments, reinvested dividends, or other distributions; and (2) ongoing
costs, including management fees; distribution and/or service (12b-1) fees; and
other Fund expenses. This example is intended to help you understand your
ongoing costs (in dollars) of investing in the Fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

     This example is based on an investment of $1,000 invested on July 1, 2004
and held for the six months ended December 31, 2004.

     ACTUAL EXPENSES

     The table below titled "Based on Actual Total Return" provides information
about actual account values and actual expenses. You may use the information
provided in this table, together with the amount you invested, to estimate the
expenses that you paid over the period. To estimate the expenses you paid on
your account, divide your ending account value by $1,000 (for example, an $8,600
ending account value divided by $1,000 = 8.6), then multiply the result by the
number under the heading entitled "Expenses Paid During the Period".

(1) For the six months ended December 31, 2004.
(2) Assumes reinvestment of dividends and capital gains distributions, if any,
    at net asset value. Total return is not annualized, as it may not be
    representative of the total return for the year. Total returns do not
    reflect expenses associated with the separate account such as administrative
    fees, account charges and surrender charges, which, if reflected, would
    reduce the total returns. Performance figures may reflect voluntary fee
    waivers and/or expense reimbursements. Past performance is no guarantee of
    future results. In the absence of voluntary fee waivers and/or expense
    reimbursements, the total return would have been lower.
(3) Expenses (net of voluntary fee waiver and/or expense reimbursement) are
    equal to the Fund's annualized expense ratio multiplied by the average
    account value over the period, multiplied by the number of days in the most
    recent fiscal half-year, then divided by 366.

                                                                              15

 FUND EXPENSES (UNAUDITED) (CONTINUED)

     HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

     The table below titled "Based on Hypothetical Total Return" provides
information about hypothetical account values and hypothetical expenses based on
the actual expense ratio and an assumed rate of return of 5.00% per year before
expenses, which is not the Fund's actual return. The hypothetical account values
and expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. You may use the information provided in this
table to compare the ongoing costs of investing in the Fund and other funds. To
do so, compare the 5.00% hypothetical example relating to the Fund with the
5.00% hypothetical examples that appear in the shareholder reports of the other
funds.

     Please note that the expenses shown in the table below are meant to
highlight your ongoing costs only and do not reflect any transactional costs,
such as front-end or back-end sales charges (loads). Therefore, 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.

 BOND RATINGS (UNAUDITED)

The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Service ("Standard & Poor's") -- Ratings from "AA" to
"CCC" may be modified by the addition of a plus (+) or minus (-) sign to show
relative standings within the major rating categories.

<Table>
                  
AAA                --   Bonds rated "AAA" have the highest rating assigned by
                        Standard & Poor's. Capacity to pay interest and repay
                        principal is extremely strong.
AA                 --   Bonds rated "AA" have a very strong capacity to pay interest
                        and repay principal and differ from the highest rated issue
                        only in a small degree.
A                  --   Bonds rated "A" have a strong capacity to pay interest and
                        repay principal although they are somewhat more susceptible
                        to the adverse effects of changes in circumstances and
                        economic conditions than bonds in higher rated categories.
BBB                --   Bonds rated "BBB" are regarded as having an adequate
                        capacity to pay interest and repay principal. Whereas they
                        normally exhibit adequate protection parameters, adverse
                        economic conditions or changing circumstances are more
                        likely to lead to a weakened capacity to pay interest and
                        repay principal for bonds in this category than in higher
                        rated categories.
BB, B, CCC and CC  --   Bonds rated "BB", "B", "CCC" and "CC" are regarded, on
                        balance, as predominantly speculative with respect to the
                        issuer's capacity to pay interest and repay principal in
                        accordance with the terms of the obligation. "BB" indicates
                        the lowest degree of speculation and "CC" the highest degree
                        of speculation. While such bonds will likely have some
                        quality and protective characteristics, these are outweighed
                        by large uncertainties or major risk exposures to adverse
                        conditions.
</Table>

Moody's Investors Service ("Moody's") -- Numerical modifiers 1, 2, and 3 may be
applied to each generic rating from "Aa" to "Caa", where 1 is the highest and 3
the lowest ranking within its generic category.
<Table>
                  
Aaa                --   Bonds rated "Aaa" are judged to be of the best quality. They
                        carry the smallest degree of investment risk and are
                        generally referred to as "gilt edge." Interest payments are
                        protected by a large or by an exceptionally stable margin
                        and principal is secure. While the various protective
                        elements are likely to change, such changes as can be
                        visualized are most unlikely to impair the fundamentally
                        strong position of such an issue.
Aa                 --   Bonds rated "Aa" are judged to be of high quality by all
                        standards. Together with the "Aaa" group they comprise what
                        are generally known as high grade bonds. They are rated
                        lower than the best bonds because margins of protection may
                        not be as large in "Aaa" securities or fluctuation of
                        protective elements may be of greater amplitude or there may
                        be other elements present which make the long-term risks
                        appear somewhat larger than in "Aaa" securities.
A                  --   Bonds rated "A" possess many favorable investment attributes
                        and are to be considered as upper medium grade obligations.
                        Factors giving security to principal and interest are
                        considered adequate but elements may be present which
                        suggest a susceptibility to impairment some time in the
                        future.
Baa                --   Bonds rated "Baa" are considered as medium grade
                        obligations; i.e., they are neither highly protected nor
                        poorly secured. Interest payments and principal security
                        appear adequate for the present but certain protective
                        elements may be lacking or may be characteristically
                        unreliable over any great length of time. Such bonds lack
                        outstanding investment characteristics and in fact have
                        speculative characteristics as well.
Ba                 --   Bonds rated "Ba" are judged to have speculative elements;
                        their future cannot be considered as well assured. Often the
                        protection of interest and principal payments may be very
                        moderate and thereby not well safeguarded during both good
                        and bad times over the future. Uncertainty of position
                        characterizes bonds in this class.
B                  --   Bonds rated "B" generally lack characteristics of desirable
                        investments. Assurance of interest and principal payments or
                        of maintenance of other terms of the contract over any long
                        period of time may be small.
Caa                --   Bonds rated "Caa" are of poor standing. Such issues may be
                        in default, or there may be present elements of danger with
                        respect to principal or interest.
Ca                 --   Bonds rated "Ca" represent obligations which are speculative
                        in a high degree. Such issues are often in default or have
                        other marked shortcomings.
C                  --   Bonds rated "C" are the lowest rated class of bonds, and
                        issues so rated can be regarded as having extremely poor
                        prospects of ever attaining any real investment standing.

NR                 --   Indicates that the bond is not rated by Standard & Poor's or
                        Moody's.

(1) Per share amounts have been calculated using the monthly average shares
    method.

(2) Effective January 1, 2001, the Fund adopted a change in the accounting
    method that requires the Fund to amortize premiums and accrete all
    discounts. Without the adoption of this change, for the year ended December
    31, 2001, the ratio of net investment income to average net assets would
    have been 3.99%. Per share information, ratios and supplemental data for the
    periods prior to January 1, 2001 have not been restated to reflect this
    change in presentation. In addition, the impact of this change to net
    investment income and net realized and unrealized loss was less than $0.01
    per share.

(3) Total returns do not reflect expenses associated with your variable contract
    such as administrative fees, account charges and surrender charges which, if
    reflected, would reduce the total returns for all periods shown. Performance
    figures may reflect voluntary fee waivers and/or expense reimbursements.
    Past performance is no guarantee of future results. In the absence of
    voluntary fee waivers and/or expense reimbursements, the total return would
    have been lower.

(4) As a result of an expense limitation, the ratio of expenses to average net
    assets will not exceed 0.80%.

(5) During the year ended December 31, 2004, Smith Barney Fund Management LLC
    voluntarily waived a portion of its fee and/or reimbursed the Fund for
    certain expenses. If such fees were not voluntarily waived and/or expenses
    reimbursed, the actual expense ratio would have been 0.75%.

(6) The Travelers Insurance Company has agreed to reimburse the Fund for certain
    expenses for the years ended December 31, 2002 and December 31, 2000. If
    such expenses were not reimbursed, the actual expense ratios would have been
    0.81% and 0.90% for the years ended December 31, 2002 and 2000,
    respectively.

 NOTES TO FINANCIAL STATEMENTS

     1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     The Convertible Securities, MFS Mid Cap Growth and Merrill Lynch Large Cap
Core Portfolios ("Fund(s)") are separate investment funds of The Travelers
Series Trust ("Trust"). The Convertible Securities Portfolio and the Merrill
Lynch Large Cap Core Portfolio are separate diversified investment funds of the
Trust. The MFS Mid Cap Growth Portfolio is a separate non-diversified investment
fund of the Trust. The Trust is a Massachusetts business trust registered under
the Investment Company Act of 1940, as amended, as an open-end management
investment company. The Funds and the other investment funds of the Trust are
offered exclusively for use with certain variable annuity and variable life
insurance contracts offered through the separate accounts of various affiliated
life insurance companies. Shares of the Trust are offered exclusively for use
with certain variable annuity and variable life insurance contracts offered
through the separate accounts of various affiliated life insurance companies.

     The following are significant accounting policies consistently followed by
the Funds and are in conformity with U.S. generally accepted accounting
principles ("GAAP"). Estimates and assumptions are required to be made regarding
assets, liabilities and changes in net assets resulting from operations when
financial statements are prepared. Changes in the economic environment,
financial markets and any other parameters used in determining these estimates
could cause actual results to differ.

     (A) INVESTMENT VALUATION.  Securities traded on national securities markets
are valued at the closing price on such markets or, if there were no sales
during the day, at the mean between the closing bid and asked prices. Securities
primarily traded on foreign exchanges are generally valued at the closing values
of such securities on their respective exchanges. Securities listed on the
NASDAQ National Market System for which market quotations are available are
valued at the official closing price or, if there is no official closing price
on that day, at the last sale price. Securities traded in the over-the-counter
market are valued at prices based on market quotations for securities of similar
type. U.S. government agencies and obligations are valued at the mean between
the last reported bid and asked prices. Securities other than U.S. government
agencies that have a maturity of 60 days or more are valued at prices based on
market quotations for securities of similar type, yield and maturity. When
market quotations or official closing prices are not readily available, or are
determined not to reflect fair value, such as when the value of a security has
been significantly affected by events after the close of the exchange or market
on which the security is principally traded, but before the Funds calculate
their net asset values, the Funds may value these investments at fair value as
determined in accordance with the procedures approved by the Funds' Board of
Trustees. Short-term obligations with maturities of 60 days or less are valued
at amortized cost, which approximates value.

     (B) REPURCHASE AGREEMENTS.  When entering into repurchase agreements, it is
the Funds' policy that a custodian takes possession of the underlying collateral
securities, the value of which at least equals the principal amount of the
repurchase transaction, including accrued interest. To the extent that any
repurchase transaction exceeds one business day, the value of the collateral is
marked-to-market to ensure the adequacy of the collateral. If the seller
defaults and the value of the collateral declines of if bankruptcy proceedings
are commenced with respect to the seller of the security, realization of the
collateral by the Funds may be delayed or limited.

     (C) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  Security transactions are
accounted for on a trade date basis. 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 dividends are recorded on
the ex-dividend date or as soon as practical after the Funds determine the
existence of a dividend declaration after exercising reasonable due diligence.
The cost of investments sold is determined by use of the specific identification
method.

     (D) FOREIGN CURRENCY TRANSLATION.  The books and records of the Funds are
maintained in U.S. dollars. Transactions denominated in foreign currencies are
recorded at the current prevailing exchange rates. All assets and liabilities
denominated in foreign currencies are translated into U.S. dollar amounts at the
current exchange rates at the end of the period. Translation gains or losses
resulting from changes in the exchange rates during the reporting period and
realized gains and losses on the settlement of foreign currency transactions are
reported in the statement of operations for the current period. The Funds do not
isolate that portion of realized gains and losses on investments in securities,
which are due to changes in the foreign exchange rates from that which is due to
changes in market prices of equity securities

     (E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends from net
investment income and distributions of net realized gains to shareholders of the
Funds, if any, are declared at least annually. Dividends and distributions to
shareholders of the Funds are recorded on the ex-dividend date and are
determined in accordance with income tax regulations which may differ from GAAP.

- --------------------------------------------------------------------------------
 NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     (F) FEDERAL AND OTHER TAXES.  It is the Funds' policy to comply with the
federal income and excise tax requirements of the Internal Revenue Code of 1986,
as amended, applicable to regulated investment companies. Accordingly, the Funds
intend to distribute substantially all of their taxable income and net realized
gains on investments, if any, to shareholders each year. Therefore, no federal
income tax provision is required. Under the applicable foreign tax law, a
withholding tax may be imposed on interest, dividends and capital gains at
various rates.

     (G) RECLASSIFICATION.  GAAP requires that certain components of net assets
be adjusted to reflect permanent differences between financial and tax
reporting. Accordingly, during the current year, $15,635 has been reclassified
between undistributed net investment income and accumulated net realized loss
from investment transactions due to the tax treatment of distributions from Real
Estate Investment Trusts and the differences between book and tax amortization
of premium on fixed income securities for Convertible Securities Portfolio.
Additionally, $1,274,710 has been reclassified between paid-in capital and
accumulated net investment loss as a result of permanent differences
attributable to a tax net operating loss, $5,927 has been reclassified between
accumulated net realized loss and paid-in capital as a result of the different
book/tax treatment of various items and $5,665 has been reclassified between
accumulated net realized loss from investment transactions and net investment
loss due to differences between book foreign currency transactions treated as
ordinary income for tax purposes for the MFS Mid Cap Growth Portfolio. Finally,
$14,926 has been reclassified between paid-in capital and accumulated net
investment loss as a result of permanent differences attributable to an
overdistribution of net investment income and $2,189 has been reclassified
between accumulated net realized loss from investment transactions and options
and accumulated net investment loss as a result of permanent differences due to
book foreign currency transactions treated as ordinary income for tax purposes
for the Merrill Lynch Large Cap Core Portfolio. These reclassifications have no
effect on net assets or net asset values per share.

   These amounts will be available to offset any future taxable capital gains.

** The difference between book-basis and tax-basis unrealized appreciation is
   attributable primarily to the tax deferral of losses on wash sales and the
   difference between book and tax amortization methods for premiums and
   discounts on fixed income securities.

     The Funds are liable for excise tax payments resulting from the timing of
required distribution payments made to taxable shareholders for the years
1999-2001. The actual amount of the liability is not yet determinable. However,
the Funds have been indemnified by SBFM for any associated excise tax liability
as well as any interest and penalties or any other costs. Accordingly, the net
asset values of the Funds will not be impacted by the outcome of this matter.

     6.  ADDITIONAL INFORMATION

     In connection with an investigation previously disclosed by Citigroup, the
Staff of the Securities and Exchange Commission ("SEC") has notified Citigroup
Asset Management ("CAM"), the Citigroup business unit that includes the funds'
investment manager and other investment advisory companies; Citicorp Trust Bank
("CTB"), an affiliate of CAM; Thomas W. Jones, the former CEO of CAM; and three
other individuals, one of whom is an employee and two of whom are former
employees of CAM, that the SEC Staff is considering recommending a civil
injunctive action and/or an administrative proceeding against each of them
relating to the creation and operation of an internal transfer agent unit to
serve various CAM-managed funds.

     In 1999, CTB entered the transfer agent business. CTB hired an unaffiliated
subcontractor to perform some of the transfer agent services. The subcontractor,
in exchange, had signed a separate agreement with CAM in 1998 that guaranteed
investment management revenue to CAM and investment banking revenue to a CAM
affiliate. The subcontractor's business was later taken over by PFPC Inc., and
at that time the revenue guarantee was eliminated and a one-time payment was
made by the subcontractor to a CAM affiliate.

     CAM did not disclose the revenue guarantee when the boards of various
CAM-managed funds hired CTB as transfer agent. Nor did CAM disclose to the
boards of the various CAM-managed funds the one-time payment received by the CAM
affiliate when it was made. As previously disclosed, CAM has already paid the
applicable funds, primarily through voluntary fee waivers, a total of
approximately $17 million (plus interest), which is the amount of the revenue
received by Citigroup relating to the revenue guarantee.

     In addition, the SEC Staff has indicated that it is considering
recommending action based on the adequacy of the disclosures made to the fund
boards that approved the transfer agency arrangement, CAM's initiation and
operation of, and compensation for, the transfer agent business and CAM's
retention of, and agreements with, the subcontractor.

     Citigroup is cooperating fully in the SEC's investigation and is seeking to
resolve the matter in discussions with the SEC Staff. On January 20, 2005,
Citigroup stated that it had established an aggregate reserve of $196 million
($25 million in the third quarter of 2004 and $171 million in the fourth quarter
of 2004) related to its discussions with the SEC Staff. Settlement negotiations
are ongoing and any settlement of this matter with the SEC will require approval
by the Citigroup Board and acceptance by the Commission.

     Unless and until any settlement is consummated, there can be no assurance
that any amount reserved by Citigroup will be distributed. Nor is there at this
time any certainty as to how the proceeds of any settlement would be
distributed, to whom any such distribution would be made, the methodology by
which such distribution would be allocated, and when such distribution would be
made.

     Although there can be no assurance, Citigroup does not believe that this
matter will have a material adverse effect on the funds.

 NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     7.  SUBSEQUENT EVENT

     On January 31, 2005, Citigroup announced that it has reached an agreement
with MetLife, Inc. ("MetLife") to sell Citigroup's life insurance and annuity
businesses ("Travelers Life & Annuity") to MetLife. As part of this transaction,
TAMIC, currently an indirect wholly owned subsidiary of Citigroup, would become
an indirect wholly owned subsidiary of MetLife. TAMIC is the investment adviser
to the Funds.

     The transaction is subject to certain regulatory approvals, as well as
other customary conditions to closing. The transaction is expected to close this
summer.

     In connection with this transaction, the Trust's Board of Trustees will be
asked to approve new investment advisory and administrative services contracts,
and, to the extent required by law, variable annuity and variable life contract
owners, who beneficially own the shares of the funds, will be asked to approve
new investment advisory agreements.

                                                                              45

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
THE TRAVELERS SERIES TRUST:

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments, of Convertible Securities Portfolio, MFS Mid Cap
Growth Portfolio, and Merrill Lynch Large Cap Core Portfolio of The Travelers
Series Trust ("Trust"), as of December 31, 2004, and the related statements of
operations for the year then ended, the statements of changes in net assets for
each of the years in the two-year period then ended, and the financial
highlights for each of the years in the five-year period then ended. These
financial statements and financial highlights are the responsibility of the
Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the auditing standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
An audit includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 2004, by correspondence with
the custodian and brokers or by other appropriate auditing procedures where
replies from brokers were not received. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Convertible Securities Portfolio, MFS Mid Cap Growth Portfolio, and Merrill
Lynch Large Cap Core Portfolio of The Travelers Series Trust as of December 31,
2004, and the results of their operations for the year then ended, the changes
in their net assets for each of the years in the two-year period then ended, and
the financial highlights for each of the years in the five-year period then
ended, in conformity with U.S. generally accepted accounting principles.

                                                                    /s/ KPMG LLP

      (d)     All Other Fees for The Travelers Series Trust of $0 and $0 for

      (e)     (1) Audit Committee's pre-approval policies and procedures
         described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

         The Charter for the Audit Committee (the "Committee") of the Board of
         each registered investment company (the "Fund") advised by Smith Barney
         Fund Management LLC or Salomon Brothers Asset Management Inc or one of
         their affiliates (each, an "Adviser") requires that the Committee shall
         approve (a) all audit and permissible non-audit services to be provided
         to the Fund and (b) all permissible non-audit services to be provided
         by the Fund's independent auditors to the Adviser and any Covered
         Service Providers if the engagement relates directly to the operations
         and financial reporting of the Fund. The Committee may implement
         policies and procedures by which such services are approved other than
         by the full Committee.

         The Committee shall not approve non-audit services that the Committee
         believes may impair the independence of the auditors. As of the date of
         the approval of this Audit Committee Charter, permissible non-audit
         services include any professional services (including tax services),
         that are not prohibited services as described below, provided to the
         Fund by the independent auditors, other than those provided to the Fund
         in connection with an audit or a review of the financial statements of
         the Fund. Permissible non-audit services may not include: (i)
         bookkeeping or other services related to the accounting records or
         financial statements of the Fund; (ii) financial information systems
         design and implementation; (iii) appraisal or valuation services,
         fairness opinions or contribution-in-kind reports; (iv) actuarial
         services; (v) internal audit outsourcing services; (vi) management
         functions or human resources; (vii) broker or dealer, investment
         adviser or investment banking services; (viii) legal services and
         expert services unrelated to the audit; and (ix) any other service the
         Public Company Accounting Oversight Board determines, by regulation, is
         impermissible.

         Pre-approval by the Committee of any permissible non-audit services is
         not required so long as: (i) the aggregate amount of all such
         permissible non-audit services provided to the Fund, the Adviser and
         any service providers controlling, controlled by or under common
         control with the Adviser that provide ongoing services to the Fund
         ("Covered Service Providers") constitutes not more than 5% of the total
         amount of revenues paid to the independent auditors during the fiscal
         year in which the permissible non-audit services are provided to (a)
         the Fund, (b) the Adviser and (c) any entity controlling, controlled by
         or under common control with the Adviser that provides ongoing services
         to the Fund during the fiscal year in which the services are provided
         that would have to be approved by the Committee; (ii) the permissible
         non-audit services were not recognized by the Fund at the time of the
         engagement to be non-audit services; and (iii) such services are
         promptly brought to the attention of the Committee and approved by the
         Committee (or its delegate(s)) prior to the completion of the audit.

         (2) For The Travelers Series Trust, the percentage of fees that were
         approved by the audit committee, with respect to: Audit-Related Fees
         were 100% and 100% for the years ended 12/31/04 and 12/31/03; Tax Fees
         were 100% and 100% for the years ended 12/31/04 and 12/31/03; and Other
         Fees were 100% and 100% for the years ended 12/31/04 and 12/31/03.

      (f)     N/A

      (g)     Non-audit fees billed by the Accountant for services rendered
         to Travelers Series Trust and CAM and any entity controlling,
         controlled by, or under common control with CAM that provides ongoing
         services to Travelers Series Trust. Fees billed to and paid by
         Citigroup Global Markets, Inc. related to the transfer agent matter as
         fully described in the notes to the financial statements titled
         "additional information" were $75,000 and $0 for the years ended
         12/31/04 and 12/31/03.

      (h)     Yes. The Travelers Series Trust's Audit Committee has
         considered whether the provision of non-audit services that were
         rendered to Service Affiliates which were not pre-approved (not
         requiring pre-approval) is compatible with maintaining the Accountant's
         independence. All services provided by the Accountant to the Travelers
         Series Trust or to Service Affiliates which were required to be
         pre-approved were pre-approved as required.

ITEM 10. CONTROLS AND PROCEDURES.

         (a)   The registrant's principal executive officer and principal
               financial officer have concluded that the registrant's disclosure
               controls and procedures (as defined in Rule 30a- 3(c) under the
               Investment Company Act of 1940, as amended (the "1940 Act")) are
               effective as of a date within 90 days of the filing date of this
               report that includes the disclosure required by this paragraph,
               based on their evaluation of the disclosure controls and
               procedures required by Rule 30a-3(b) under the 1940 Act and
               15d-15(b) under the Securities Exchange Act of 1934.

         (b)   There were no changes in the registrant's internal control over
               financial reporting (as defined in Rule 30a-3(d) under the 1940
               Act) that occurred during the registrant's last fiscal half-year
               (the registrant's second fiscal half-year in the case of an
               annual report) that have materially affected, or are likely to
               materially affect the registrant's internal control over
               financial reporting.
