                                                    2004 SEMI-ANNUAL REPORT

                                                    March 31, 2004 (unaudited)

NOTES TO FINANCIAL STATEMENTS

Morgan Stanley Institutional Fund Trust ("MSIFT" or the "Fund") is registered
under the Investment Company Act of 1940 as an open-end investment company. The
Fund is comprised of nineteen active portfolios. The accompanying financial
statements and financial highlights are those of the Equity, Mid Cap Growth,
Strategic Small Value, U.S. Mid Cap Value, U.S. Small Cap Value, and Value
Portfolios, all of which are considered diversified funds for purposes of the
1940 Act (each referred to as a "Portfolio"). The financial statements of the
remaining portfolios are presented separately.

The Fund offers up to three different classes of shares for certain Portfolios -
Institutional Class shares, Investment Class shares and Adviser Class shares.
Each class of shares has identical voting rights (except shareholders of a Class
have exclusive voting rights regarding any matter relating solely to that Class
of shares), dividend, liquidation and other rights, except each class bears
different distribution or service fees as described in Note D. The Strategic
Small Value and U.S. Small Cap Value Portfolios are authorized to issue
unlimited shares per class but are currently closed to new accounts.

A. SIGNIFICANT ACCOUNTING POLICIES. The following significant accounting
policies are in conformity with accounting principles generally accepted in the
United States for investment companies. Such policies are consistently followed
by the Fund in the preparation of its financial statements. Accounting
principles generally accepted in the United States may require management to
make estimates and assumptions that affect the reported amounts and disclosures
in the financial statements. Actual results may differ from those estimates.

1. SECURITY VALUATION: Equity securities listed on a U.S. exchange are valued at
   the latest quoted sales price on the valuation date. Equity securities listed
   or traded on NAS-DAQ, for which market quotations are available, are valued
   at the NASDAQ Official Closing Price. Securities listed on a foreign exchange
   are valued at their closing price. Unlisted securities and listed securities
   not traded on the valuation date for which market quotations are readily
   available are valued at the mean between the current bid and asked prices
   obtained from reputable brokers. Debt securities purchased with remaining
   maturities of 60 days or less are valued at amortized cost, if it
   approximates value.

   All other securities and investments for which market values are not readily
   available, including restricted securities, and those securities for which it
   is inappropriate to determine prices in accordance with the aforementioned
   procedures, are valued at fair value as determined in good faith under
   procedures adopted by the Board of Trustees, although the actual calculations
   may be done by others. Factors considered in making this determination may
   include, but are not limited to, information obtained by contacting the
   issuer, analysts, or the appropriate stock exchange (for exchange-traded
   securities), analysis of the issuer's financial statements or other available
   documents and, if necessary, available information concerning other
   securities in similar circumstances.

2. REPURCHASE AGREEMENTS: Each Portfolio may enter into repurchase agreements
   under which a Portfolio lends excess cash and takes possession of securities
   with an agreement that the counterparty will repurchase such securities. In
   connection with transactions in repurchase agreements, a bank as custodian
   for the Fund takes possession of the underlying securities which are held as
   collateral, with a market value at least equal to the amount of the
   repurchase transaction, including principal and accrued interest. To the
   extent that any repurchase transaction exceeds one business day, the value of
   the of the collateral is marked-to-market on a daily basis to determine the
   adequacy of the collateral. In the event of default on the obligation to
   repurchase, the Fund has the right to liquidate the collateral and apply the
   proceeds in satisfaction of the obligation. In the event of default or
   bankruptcy by the counterparty to the agreement, realization and/or retention
   of the collateral or proceeds may be subject to legal proceedings.

   Pursuant to an exemptive order issued by the Securities and Exchange
   Commission, the Portfolios may transfer their uninvested cash balances into a
   joint trading account with other Portfolios of the Fund which invests in one
   or more repurchase agreements. Any such joint repurchase agreement is covered
   by the same collateral requirements as discussed above.

3. FOREIGN CURRENCY TRANSLATION AND FOREIGN CURRENCY EXCHANGE CONTRACTS: The
   books and records of the Fund are maintained in U.S. dollars. Foreign
   currency amounts are translated into U.S. dollars at the bid prices of such
   currencies against U.S. dollars quoted by a bank. Net realized gains (losses)
   on foreign currency transactions represent net foreign exchange gains
   (losses) from foreign currency exchange contracts, disposition of foreign
   currencies, currency gains or losses realized between the trade and
   settlement dates on securities transactions, and the difference between the
   amount of investment income and foreign withholding taxes recorded on a
   Portfolio's books and the U.S. dollar equivalent of amounts actually received
   or paid.

   A foreign currency exchange contract is an agreement between two parties to
   buy or sell currency at a set price on a future date. Each Portfolio (except
   the Mid Cap Growth Portfolio) may enter into foreign currency exchange
   contracts to protect securities and related receivables and payables against
   future changes in foreign exchange rates.

                                                                              27

2004 SEMI-ANNUAL REPORT

March 31, 2004 (UNAUDITED)

NOTES TO FINANCIAL STATEMENTS (CONT'D)

   Fluctuations in the value of such contracts are recorded as unrealized
   appreciation or depreciation; realized gains or losses, which are disclosed
   in the Statement of Operations, include net gains or losses on contracts
   which have been terminated by settlements. Risks may arise upon entering into
   these contracts from the potential inability of counterparties to meet the
   terms of their contracts and are generally limited to the amount of
   unrealized gain on the contract, if any, at the date of default. Risks may
   also arise from unanticipated movements in the value of the foreign currency
   relative to the U.S. dollar.

   The Portfolios do not isolate that portion of the results of operations
   arising as a result of changes in the foreign exchange rates from the
   fluctuations arising from changes in the market prices of the securities held
   at period end. Similarly, the Portfolios do not isolate the effect of changes
   in foreign exchange rates from the fluctuations arising from changes in the
   market prices of securities sold during the period. Accordingly, the
   components of realized and unrealized foreign currency gains (losses)
   representing foreign exchange changes on investments is included in the
   reported net realized and unrealized gains (losses) on investment
   transactions and balances. Changes in currency exchange rates will affect the
   value of and investment income from such securities and currency.

   Foreign security and currency transactions may involve certain considerations
   and risks not typically associated with those of U.S. dollar denominated
   transactions as a result of, among other factors, the possibly lower level of
   governmental supervision, relative currency valuation fluctuation, regulation
   of foreign securities markets and the possibility of political or economic
   instability.

4. OTHER: Security transactions are accounted for on the date the securities
   are purchased or sold. Costs used in determining realized gains and losses on
   the sale of investment securities are those of specific securities sold.

   Interest income is recognized on the accrual basis. Discounts and premiums on
   securities purchased are amortized over their respective lives. Most expenses
   of the Fund can be directly attributed to a particular Portfolio. Expenses
   which cannot be directly attributed are apportioned among the Portfolios on
   the basis of their relative net assets. Income, expenses (other than class
   specific expenses) and realized and unrealized gains or losses are allocated
   to each class of shares based upon their relative net assets.

B. INVESTMENT ADVISORY FEE. Under the terms of an Investment Advisory Agreement,
each Portfolio has agreed to pay Morgan Stanley Investment Management Inc. ("MS
Investment Management," formerly Morgan Stanley Investments LP, or the
"Adviser"), a wholly-owned subsidiary of Morgan Stanley, for investment advisory
services performed at a fee calculated by applying a quarterly rate based on an
annual percentage rate to each Portfolio's average daily net assets for the
quarter.

</Table>

The Adviser has voluntarily agreed to reduce the fees payable to it and, if
necessary, reimburse the Strategic Small Value Portfolio for certain expenses so
that annual operating expenses, after giving effect to custody fee offsets, will
not exceed voluntary expense limitations established for each class of shares as
presented in the table above.

C. ADMINISTRATOR. MS Investment Management (the "Administrator") also provides
the Fund with administrative services pursuant to an administrative agreement
for a monthly fee which on an annual basis equals 0.08% of the average daily net
assets of each Portfolio, plus reimbursement of out-of-pocket expenses. Under an
agreement between the Administrator and J.P. Morgan Investor Services Co.
("JPMIS"), a corporate affiliate of JPMorgan Chase Bank, JPMIS provides certain
administrative services to the Fund. For such services, the Administrator pays
JPMIS a portion of the fee the Administrator receives from the Fund. An employee
of JPMIS is an officer of the Fund.

D. DISTRIBUTOR. Morgan Stanley Distribution, Inc. ("MSDI" or the "Distributor"),
a wholly owned subsidiary of the Adviser, is the distributor for the Fund. MSDI
is a limited-purpose broker/dealer whose only function is to distribute open-end
mutual fund shares. The Distributor provides all classes of shares in each
Portfolio with distribution services, and receives fees in connection with these
services, pursuant to separate Distribution and Shareholder Servicing Plans (the
"Plans") in accordance with Rule 12b-1 under the Investment Company Act of 1940.

Under the Plans, the Distributor is entitled to distribution fees and
shareholder servicing fees for Adviser Class and Investment Class shares,
respectively. The distribution fee is an asset-based fee to support distribution
efforts and/or servicing of accounts. The Adviser Class of shares pays a
distribution fee of 0.25% of average net assets of the class for such services
under the 12b-1 plan adopted by the Fund. The Investment Class of

shares pays a shareholder servicing fee of 0.15% of average net assets of the
class. The shareholder servicing fee is used to support the expenses associated
with servicing and maintaining accounts. Both fees are paid directly to MSDI.
The distribution fee may be retained by MSDI if an Adviser Class shareholder
invests directly through MSDI. Usually the fees are paid by MSDI to external
organizations such as 401(k) alliance sponsors, discount brokers and bank trust
departments who distribute MSIFT Portfolios to the public.

E. CUSTODY. JPMorgan Chase Bank serves as custodian for the Fund in accordance
with a custodian agreement. The Custodian holds cash, securities, and other
assets of the Fund as required by the 1940 Act.

The Portfolios have entered into an arrangement with their custodian whereby
credits realized on uninvested cash balances were used to offset a portion of
each applicable Portfolio's expenses. These custodian credits are shown as
"expense offsets" on the Statement of Operations.

F. PORTFOLIO INVESTMENT ACTIVITY.

G. SECURITIES LENDING. Certain Portfolios may lend investment securities to
qualified financial institutions, such as broker-dealers, to earn additional
income. Any increase or decrease in the fair value of the securities loaned that
might occur and any interest earned or dividends declared on those securities
during the term of the loan would remain in the Portfolio. Portfolios that lend
securities receive cash or securities as collateral in an amount equal to or
exceeding 100% of the current fair value of the loaned securities. The
collateral is marked to market daily, by the securities lending agent, to ensure
that a minimum of 100% collateral coverage is maintained.

Based on pre-established guidelines, the securities lending agent invests any
cash collateral that is received in high-quality short-term investments. The
Portfolio retains a portion of the income derived from these investments, which
is included in the Statement of Operations in interest income. Risks in
securities lending transactions are that a borrower may not provide additional
collateral when required or return the securities when due, and that the value
of the short-term investments will be less than the amount of cash collateral
plus any rebate that is required to be returned to the borrower. The value of
loaned securities and related collateral outstanding at March 31, 2004 are as
follows:

H. FEDERAL INCOME TAXES. It is each Portfolio's intention to continue to qualify
as a regulated investment company and distribute all of its taxable income.
Accordingly, no provision for Federal income taxes is required in the financial
statements. Dividend income and distributions to shareholders are recorded on
the ex-dividend date.

Dividends from net investment income, if any, are declared and paid quarterly
for the Equity and Value Portfolios. The Mid Cap Growth, Strategic Small Value,
U.S. Mid Cap Value, and U.S. Small Cap Value Portfolios dividends are declared
and paid annually. Net realized capital gains are distributed at least annually.

The tax character of distributions paid may differ from the character of
distributions shown on the Statement of Changes in Net Assets due to short-term
capital gains being treated as ordinary income for tax purposes. As of September
30, 2003,

                                                                              29

</Table>

The amount and character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from accounting
principles generally accepted in the United States. The book/tax differences are
either considered temporary or permanent in nature.

Temporary differences are generally due to differing book and tax treatments in
the timing of the recognition of gains or losses on securities, forwards and
futures, including Post October Losses. Permanent differences are generally due
to REIT adjustments, gain (loss) on in-kind redemptions, foreign currency
transactions and gains on certain equity securities designated as issued by
"passive foreign investment companies".

Permanent book and tax basis differences may result in reclassifications to
undistributed (distributions in excess of) net investment income (or accumulated
net investment loss), accumulated net realized gain (loss) and paid-in capital.

As of September 30, 2003, the components of distributable earnings on a tax
basis were as follows:

2004 SEMI-ANNUAL REPORT

March 31, 2004 (unaudited)

SHAREHOLDER'S LETTER


Dear Shareholders:

We are pleased to present to you the Fund's Semi-Annual Report for the six
months ended March 31, 2004. Our Fund currently consists of 19 portfolios,
providing investors with a broad array of equity, fixed- income, and balanced
portfolios. The Fund's portfolios, together with the portfolios of the Morgan
Stanley Institutional Fund, Inc., provide investors with a means to help them
meet specific investment needs and to allocate their investments among equities
(e.g., value and growth; small, medium, and large capitalization), and fixed
income (e.g., short, medium, and long duration; investment grade and high

^    The Portfolio's turnover rate is calculated by dividing the lesser of
     purchases and sales of securities for a fiscal year by the average monthly
     value of the portfolio securities during such fiscal year. The turnover
     rate may vary greatly from year to year as well as within a year. The
     Portfolio's current year turnover rate reflects mortgage pool forward
     commitments as purchases and sales, which was not the case in the past
     years. The inclusion of such securities caused the reported turnover rate
     to be higher during the period than in previous fiscal years.

                                                     2004 SEMI-ANNUAL REPORT

                                                     March 31, 2004 (unaudited)
NOTES TO FINANCIAL STATEMENTS

Morgan Stanley Institutional Fund Trust ("MSIFT" or the "Fund") is registered
under the Investment Company Act of 1940 as an open-end investment company. The
Fund was comprised of nineteen active portfolios. The accompanying financial
statements and financial highlights are those of the Advisory Foreign Fixed
Income, Advisory Foreign Fixed Income II and Advisory Mortgage Portfolios (each
referred to as a "Portfolio") only. For the purposes of the 1940 Act, Advisory
Foreign Fixed Income and Advisory Foreign Fixed Income II Portfolios are
considered non-diversified funds; Advisory Mortgage Portfolio is considered a
diversified fund. The financial statements of the remaining portfolios are
presented separately.

A. SIGNIFICANT ACCOUNTING POLICIES. The following significant accounting
policies are in conformity with accounting principles generally accepted in the
United States. Such policies are consistently followed by the Fund in the
preparation of its financial statements. Accounting principles generally
accepted in the United States of America may require management to make
estimates and assumptions that affect the reported amounts and disclosures in
the financial statements. Actual results may differ from those estimates.

1.   SECURITY VALUATION: Equity securities listed on a U.S. exchange are valued
     at the latest quoted sales price on the valuation date. Equity securities
     listed or traded on NASDAQ, for which market quotations are available, are
     valued at the NASDAQ Official Closing Price. Securities listed on a foreign
     exchange are valued at their closing price. Unlisted and listed equity
     securities not traded on the valuation date, for which market quotations
     are readily available, are valued at the mean between the current bid and
     asked prices obtained from reputable brokers. Bonds and other fixed income
     securities may be valued according to the broadest and most representative
     market. In addition, bonds and other fixed income securities may be valued
     on the basis of prices provided by a pricing service. The prices provided
     by a pricing service take into account broker dealer market price
     quotations for institutional size trading in similar groups of securities,
     security quality, maturity, coupon and other security characteristics as
     well as any developments related to the specific security. Debt securities
     purchased with remaining maturities of 60 days or less are valued at
     amortized cost, if it approximates market value.

     All other securities and investments for which market values are not
     readily available, including restricted securities, and those securities
     for which it is inappropriate to determine prices in accordance with the
     aforementioned procedures, are valued at fair value as determined in good
     faith under procedures adopted by the Board of Trustees, although the
     actual calculations may be done by others. Factors consid ered in making
     this determination may include, but are not limited to, information
     obtained by contacting the issuer, analysts, or the appropriate stock
     exchange (for exchange-traded securities), analysis of the issuer's
     financial statements or other available documents and, if necessary,
     available information concerning other securities in similar circumstances.

     Most foreign markets close before the New York Stock Exchange (NYSE).
     Occasionally, developments that could affect the closing prices of
     securities and other assets may occur between the times at which valuations
     of such securities are determined (that is, close of the foreign market on
     which the securities trade) and the close of business on the NYSE. If these
     developments are expected to materially affect the value as of the
     securities, the valuations may be adjusted to reflect the estimated fair
     value as of the close of the NYSE, as determined in good faith under
     procedures established by the Board of Trustees.

2.   REPURCHASE AGREEMENTS: Each Portfolio may enter into repurchase agreements
     under which a Portfolio lends excess cash and takes possession of
     securities with an agreement that the counterparty will repurchase such
     securities. In connection with transactions in repurchase agreements, a
     bank as custodian for the Fund takes possession of the underlying
     securities which are held as collateral, with a market value at least equal
     to the amount of the repurchase transaction, including principal and
     accrued interest. To the extent that any repurchase transaction exceeds one
     business day, the value of the of the collateral is marked-to-market on a
     daily basis to determine the adequacy of the collateral. In the event of
     default on the obligation to repurchase, the Fund has the right to
     liquidate the collateral and apply the proceeds in satisfaction of the
     obligation. In the event of default or bankruptcy by the counterparty to
     the agreement, realization and/or retention of the collateral or proceeds
     may be subject to legal proceedings.

     Pursuant to an exemptive order issued by the Securities and Exchange
     Commission, the Portfolios may transfer their uninvested cash balances into
     a joint trading account with other Portfolios of the Fund which invests in
     one or more repurchase agreements. Any such joint repurchase agreement is
     covered by the same collateral requirements as discussed above.

3.   FUTURES: Financial futures contracts (secured by cash and securities
     deposited with brokers as "initial margin") are valued based upon their
     quoted daily settlement prices; changes in initial settlement value
     (represented by cash paid to or received from brokers as "variation
     margin") are accounted for as unrealized appreciation (depreciation). When
     futures contracts are closed, the difference between the opening

                                                                              17
<Page>
2004 SEMI-ANNUAL REPORT

March 31, 2004 (unaudited)

NOTES TO FINANCIAL STATEMENTS (CONT'D)

     value at the date of purchase and the value at closing is recorded as
     realized gain or loss in the Statement of Operations. "Due from (to)
     Broker" includes initial margin and variation margin, as stated in the
     Statement of Net Assets.

     Futures contracts may be used by each Portfolio in order to hedge against
     unfavorable changes in the value of securities or to attempt to realize
     profits from the value of the related securities.

     Futures contracts involve market risk that may exceed the amounts
     recognized in the Statement of Net Assets. Risks arise from the possible
     movements in the prices of securities relating to these instruments. The
     change in value of futures contracts primarily corresponds with the value
     of their related securities, but may not precisely correlate with the
     change in value of such securities. In addition, there is the risk that a
     Portfolio may not be able to enter into a closing transaction because of an
     illiquid secondary market.

4.   SECURITIES SOLD SHORT: Each Portfolio may sell securities short. A short
     sale is a transaction in which the Portfolio sells securities it may or may
     not own, but has borrowed, in anticipation of a decline in the market price
     of the securities. The Portfolio is obligated to replace the borrowed
     securities at their market price at the time of replacement. The Portfolio
     may have to pay a premium to borrow the securities as well as pay any
     dividends or interest payable on the securities until they are replaced.
     The Portfolio's obligation to replace the securities borrowed in connection
     with a short sale will generally be secured by collateral deposited with
     the broker that consists of cash, U.S. government securities or other
     liquid high grade debt obligations. In addition, the Portfolio will either
     place in a segregated account with its custodian or denote on its custody
     records an amount of cash, U.S. government securities or other liquid high
     grade debt obligations equal to the difference, if any, between (1) the
     market value of the securities sold at the time they were sold short and
     (2) any cash, U.S. government securities or other liquid high grade debt
     obligations deposited as collateral with the broker in connection with the
     short sale (not including the proceeds of the short sale). Short sales by
     the Portfolios involve certain risks and special considerations. Possible
     losses from short sales differ from losses that could be incurred from a
     purchase of a security because losses from short sales may be unlimited,
     whereas losses from purchases cannot exceed the total amount invested.

5.   SWAP AGREEMENTS: Each Portfolio may enter into swap agreements to exchange
     the interest rate on, or return generated by, one nominal instrument for
     the return generated by another instrument. Cash collateral for swap
     agreements, if applicable, is deposited with the broker serving as
     counter-party to the agreement, and is included in "Due from (to) Broker"
     on the Statement of Net Assets. The following summarizes swaps entered into
     by the Portfolios:

     CREDIT DEFAULT SWAPS: Credit default swaps involve commitments to pay a
     fixed rate in exchange for payment if a credit event affecting a third
     party (the referenced company) occurs. Credit events may include a failure
     to pay interest, bankruptcy, or restructuring. Net periodic interest
     payments to be received or paid are accrued daily and are recorded in the
     Statement of Operations as an adjustment to interest income. Credit default
     swaps are marked-to-market daily based upon quotations from market makers
     and the change, if any, is recorded as unrealized appreciation or
     depreciation in the Statement of Operations.

     INTEREST RATE SWAPS: Interest rate swaps involve the exchange of
     commitments to pay and receive interest based on a notional principal
     amount. Net periodic interest payments to be received or paid are accrued
     daily and are recorded in the Statement of Operations as an adjustment to
     interest income. In a zero-coupon interest rate swap, payments only occur
     at maturity, at which time one counterparty pays the total compounded fixed
     rate over the life of the swap and the other pays the total compounded
     floating rate that would have been earned had a series of LIBOR investments
     been rolled over through the life of the swap. Interest rate swaps are
     marked-to-market daily based upon quotations from market makers and the
     change, if any, is recorded as unrealized appreciation or depreciation in
     the Statement of Operations.

     TOTAL RETURN SWAPS: Total return swaps involve commitments to pay interest
     in exchange for a market-linked return based on a notional amount. To the
     extent the total return of the security or index underlying the transaction
     exceeds or falls short of the offsetting interest rate obligation, the
     Portfolio will receive a payment from or make a payment to the
     counterparty, respectively. Total return swaps are marked-to-market daily
     based upon quotations from market makers and the change, if any, is
     recorded as unrealized appreciation or depreciation in the Statement of
     Operations. Periodic payments received or made at the end of each
     measurement period, but prior to termination, are recorded as realized
     gains or losses in the Statement of Operations.

     Realized gains or losses on maturity or termination of swaps are presented
     in the Statement of Operations. Because there is no organized market for
     these swap agreements, the unrealized gain/loss reported in the Statement
     of Net Assets may differ from that which would be realized in the event the
     Portfolio terminated its position in the agreement. Risks may arise upon
     entering into these agreements from the potential inability of the
     counterparties to meet the terms of the agreements and are generally
     limited to the amount of

                                                     2004 SEMI-ANNUAL REPORT

                                                     March 31, 2004 (unaudited)
NOTES TO FINANCIAL STATEMENTS (CONT'D)

     net interest payments to be received, if any, at the date of default.

6.   STRUCTURED INVESTMENTS: Each Portfolio may invest in structured investments
     whose values are linked either directly or inversely to changes in foreign
     currencies, interest rates, commodities, indices, or other underlying
     instruments. A Portfolio uses these securities to increase or decrease its
     exposure to different underlying instruments and to gain exposure to
     markets that might be difficult to invest in through conventional
     securities. Structured investments may be more volatile than their
     underlying instruments, but any loss is limited to the amount of the
     original investment.

7.   DELAYED DELIVERY COMMITMENTS: Each Portfolio may purchase or sell
     securities on a when-issued or forward commitment basis. Payment and
     delivery may take place a month or more after the date of the transaction.
     The price of the underlying securities and the date when the securities
     will be delivered and paid for are fixed at the time the transaction is
     negotiated. Liquid securities or cash is designated in an amount at least
     equal to these commitments. Securities held for this purpose cannot be sold
     while this strategy is outstanding, unless replaced with other assets. As a
     result, there is a possibility that as designated assets reach certain
     levels, a Portfolio may lose some flexibility in managing its investments,
     responding to shareholder redemption requests, or meeting other current
     obligations.

8.   FOREIGN CURRENCY TRANSLATION AND FOREIGN CURRENCY EXCHANGE CONTRACTS: The
     books and records of the Fund are maintained in U.S. dollars. Foreign
     currency amounts are translated into U.S. dollars at the bid prices of such
     currencies against U.S. dollars quoted by a bank. Net realized gains
     (losses) on foreign currency transactions represent net foreign exchange
     gains (losses) from foreign currency exchange contracts, disposition of
     foreign currencies, currency gains or losses realized between the trade and
     settlement dates on securities transactions, and the difference between the
     amount of investment income and foreign withholding taxes recorded on a
     Portfolio's books and the U.S. dollar equivalent of amounts actually
     received or paid.

     A foreign currency exchange contract is an agreement between two parties to
     buy or sell currency at a set price on a future date. Each Portfolio may
     enter into foreign currency exchange contracts to protect securities and
     related receivables and payables against future changes in foreign exchange
     rates. Fluctuations in the value of such contracts are recorded as
     unrealized appreciation or depreciation; realized gains or losses, which
     are disclosed in the Statement of Operations, include net gains or losses
     on contracts which have been terminated by settlements. Risks may arise
     upon entering into these contracts from the potential inability of
     counterparties to meet the terms of their contracts and are generally
     limited to the amount of unrealized gain on the contract, if any, at the
     date of default. Risks may also arise from unanticipated movements in the
     value of the foreign currency relative to the U.S. dollar.

     At March 31, 2004, the Advisory Foreign Fixed Income and Advisory Foreign
     Fixed Income II Portfolio's net assets included foreign denominated
     securities and currency. The net assets of these Portfolios are presented
     at the foreign exchange rates and market values at the close of the period.
     The Portfolios do not isolate that portion of the results of operations
     arising as a result of changes in the foreign exchange rates from the
     fluctuations arising from changes in the market prices of the securities
     held at period end. Similarly, the Portfolios do not isolate the effect of
     changes in foreign exchange rates from the fluctuations arising from
     changes in the market prices of securities sold during the period.
     Accordingly, the component of realized and unrealized foreign currency
     gains (losses) representing foreign exchange changes on investments is
     included in the reported net realized and unrealized gains (losses) on
     investment transactions and balances. Changes in currency exchange rates
     will affect the value of and investment income from such securities and
     currency.

     Foreign security and currency transactions may involve certain
     considerations and risks not typically associated with those of U.S. dollar
     denominated transactions as a result of, among other factors, the possibly
     lower level of governmental supervision, relative currency valuation
     fluctuation and regulation of foreign securities markets and the
     possibility of political or economic instability.

9.   OTHER: Security transactions are accounted for on the date the securities
     are purchased or sold. Costs used in determining realized gains and losses
     on the sale of investment securities are those of specific securities sold.

     Discounts and premiums on securities purchased are accreted/amortized over
     their respective lives. Most expenses of the Fund can be directly
     attributed to a particular Portfolio. Expenses which cannot be directly
     attributed are apportioned among the Portfolios on the basis of their
     relative net assets.

B. INVESTMENT ADVISORY FEE. Under the terms of an Investment Advisory Agreement,
each Portfolio pays Morgan Stanley Investment Management Inc. ("MS Investment
Management," formerly Morgan Stanley Investments LP, or "the Adviser"), a
wholly-owned subsidiary of Morgan Stanley, for investment advisory services
performed at a fee calculated by applying a quarterly rate based on an annual
percentage

                                                                              19

rate of 0.375% of the Portfolio's average daily net assets for the quarter.

The Adviser has voluntarily agreed to reduce the fees payable to it and, if
necessary, reimburse the Portfolios if annual operating expenses exceed 0.15%,
0.15% and 0.08% of average daily net assets of the Advisory Foreign Fixed
Income, Advisory Foreign Fixed Income II and Advisory Mortgage Portfolios,
respectively.

Morgan Stanley Investment Management Limited ("MSIM Limited") serves as
Sub-Adviser to the Advisory Foreign Fixed Income Portfolio and the Advisory
Foreign Fixed Income II Portfolio. MSIM Limited is a wholly-owned subsidiary of
Morgan Stanley. Under an Investment Sub-Advisory Agreement with the Adviser,
MSIM Limited, subject to the control and supervision of the Fund, its officers,
Trustees and the Adviser, and in accordance with the investment objectives,
policies and restrictions of these Portfolios, makes certain day-to-day
investment decisions for these Portfolios and places certain of the Portfolios'
purchase and sales orders. The Adviser pays MSIM Limited on a monthly basis a
portion of the net advisory fees the Adviser receives from these Portfolios.

C. ADMINISTRATOR. MS Investment Management (the "Administrator") also provides
the Fund with administrative services pursuant to an administrative agreement
for a monthly fee which on an annual basis equals 0.08% of the average daily net
assets of each Portfolio, plus reimbursement of out-of-pocket expenses. Under an
agreement between the Administrator and J.P. Morgan Investor Services Co.
("JPMIS"), a corporate affiliate of JPMorgan Chase Bank, JPMIS provides certain
administrative services to the Fund. For such services, the Administrator pays
JPMIS a portion of the fee the Administrator receives from the Fund. An employee
of JPMIS is an officer of the Fund.

D. DISTRIBUTOR. Morgan Stanley Distribution, Inc. ("MSDI" or the "Distributor"),
a wholly owned subsidiary of the Adviser, is the distributor for the Fund. MSDI
is a limited-purpose broker/dealer whose only function is to distribute open-end
mutual fund shares.

E. CUSTODY. JPMorgan Chase Bank serves as custodian for the Fund in accordance
with a custodian agreement. The Custodian holds cash, securities, and other
assets of the Fund as required by the 1940 Act.

The Portfolios have entered into an arrangement with their custodian whereby
credits realized on uninvested cash balances were used to offset a portion of
each applicable Portfolio's expenses. These custodian credits are shown as
"expense offset" on the Statements of Operations.

2004 SEMI-ANNUAL REPORT

March 31, 2004 (unaudited)

NOTES TO FINANCIAL STATEMENTS (CONT'D)

G. FEDERAL INCOME TAXES: It is each Portfolio's intention to continue to qualify
as a regulated investment company and distribute all of its taxable income.
Accordingly, no provision for Federal income taxes is required in the financial
statements. Dividend income and distributions to shareholders are recorded on
the ex-dividend date. Interest income is recognized on the accrual basis.
Dividends from net investment income, if any, are declared and paid quarterly
for the Advisory Foreign Fixed Income and Advisory Foreign Fixed Income II
Portfolios and monthly for the Advisory Mortgage Portfolio. Net realized capital
gains are distributed at least annually.

The tax character of distributions paid may differ from the character of
distributions shown on the Statement of Changes in Net Assets due to short-term
capital gains being treated as ordinary income for tax purposes. The tax
character of distributions paid during 2003 and 2002 were as follows:

</Table>

The amount and character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from accounting
principles generally accepted in the United States. The book/tax differences are
either considered temporary or permanent in nature.

Temporary differences are generally due to a portion of certain redemptions
being treated as taxable dividends and/or capital gain distributions, and
differing book and tax treatments in the timing of the recognition of gains or
losses on securities, forwards and futures, including Post-October Losses.
Permanent differences are generally due to gain (loss) on in-kind redemptions
and foreign currency transactions.

Permanent book and tax basis differences may result in reclassifications to
undistributed (distributions in excess of) net investment income, accumulated
net realized net gain (loss) and paid-in capital.

As of September 30, 2003, the components of distributable earnings on a tax
basis were as follows:

We are pleased to present to you the Fund's Semi-Annual Report for the six

yield).


SIGNIFICANT DEVELOPMENTS

The Cash Reserves Portfolio will be liquidated on May 27, 2004. The Portfolio

^    The Portfolio's turnover rate is calculated by dividing the lesser of
     purchases and sales of securities for a fiscal year by the average monthly
     value of portfolio securities during such fiscal year. The turnover rate
     may vary greatly from year to year as well as within a year. The
     Portfolio's current year turnover rate reflects mortgage pool forward
     commitments as purchases and sales, which was not the case in past years.
     The inclusion of such securities caused the reported turnover rate to be
     higher during the period than in previous fiscal years.

^    The Portfolio's turnover rate is calculated by dividing the lesser of
     purchases and sales of securities for a fiscal year by the average monthly
     value of portfolio securities during such fiscal year. The turnover rate
     may vary greatly from year to year as well as within a year. The
     Portfolio's current year turnover rate reflects mortgage pool forward
     commitments as purchases and sales, which was not the case in past years.
     The inclusion of such securities caused the reported turnover rate to be
     higher during the period than in previous fiscal years.

^    The Portfolio's turnover rate is calculated by dividing the lesser of
     purchases and sales of securities for a fiscal year by the average monthly
     value of portfolio securities during such fiscal year. The turnover rate
     may vary greatly from year to year as well as within a year. The
     Portfolio's current year turnover rate reflects mortgage pool forward
     commitments as purchases and sales, which was not the case in past years.
     The inclusion of such securities caused the reported turnover rate to be
     higher during the period than in previous fiscal years.

^    The Portfolio's turnover rate is calculated by dividing the lesser of
     purchases and sales of securities for a fiscal year by the average monthly
     value of portfolio securities during such fiscal year. The turnover rate
     may vary greatly from year to year as well as within a year. The
     Portfolio's current year turnover rate reflects mortgage pool forward
     commitments as purchases and sales, which was not the case in past years.
     The inclusion of such securities caused the reported turnover rate to be
     higher during the period than in previous fiscal years.

**   Initial offering of Investment Class shares.
^    The Portfolio's turnover rate is calculated by dividing the lesser of
     purchases and sales of securities for a fiscal year by the average monthly
     value of portfolio securities during such fiscal year. The turnover rate
     may vary greatly from year to year as well as within a year. The
     Portfolio's current year turnover rate reflects mortgage pool forward
     commitments as purchases and sales, which was not the case in past years.
     The inclusion of such securities caused the reported turnover rate to be
     higher during the period than in previous fiscal years.

^    The Portfolio's turnover rate is calculated by dividing the lesser of
     purchases and sales of securities for a fiscal year by the average monthly
     value of portfolio securities during such fiscal year. The turnover rate
     may vary greatly from year to year as well as within a year. The
     Portfolio's current year turnover rate reflects mortgage pool forward
     commitments as purchases and sales, which was not the case in past years.
     The inclusion of such securities caused the reported turnover rate to be
     higher during the period than in previous fiscal years.

^    The Portfolio's turnover rate is calculated by dividing the lesser of
     purchases and sales of securities for a fiscal year by the average monthly
     value of portfolio securities during such fiscal year. The turnover rate
     may vary greatly from year to year as well as within a year. The
     Portfolio's current year turnover rate reflects mortgage pool forward
     commitments as purchases and sales, which was not the case in past years.
     The inclusion of such securities caused the reported turnover rate to be
     higher during the period than in previous fiscal years.

                                                  March 31, 2004 (unaudited)

NOTES TO FINANCIAL STATEMENTS

Morgan Stanley Institutional Fund Trust ("MSIFT" or the "Fund") is registered
under the Investment Company Act of 1940 as an open-end investment company. The
Fund is comprised of nineteen active portfolios. The accompanying financial
statements and financial highlights are those of the Core Plus Fixed Income,
Investment Grade Fixed Income, U.S. Core Fixed Income, Cash Reserves, High
Yield, Intermediate Duration, International Fixed Income, Limited Duration,
Municipal and Balanced Portfolios, all of which except the International Fixed
Income Portfolio are considered diversified for purposes of the 1940 Act (each
referred to as a "Portfolio"). The financial statements of the remaining
portfolios of the Fund are presented separately.

The Fund offers up to three different classes of shares for certain Portfolios
- -- Institutional Class shares, Investment Class shares and Adviser Class shares.
Each class of shares has identical voting rights (except shareholders of each
Class have exclusive voting rights regarding any matter relating solely to that
particular Class of shares), dividend, liquidation and other rights.

A. SIGNIFICANT ACCOUNTING POLICIES. The following significant accounting
policies are in conformity with accounting principles generally accepted in the
United States. Such policies are consistently followed by the Fund in the
preparation of the financial statements. Accounting principles generally
accepted in the United States may require management to make estimates and
assumptions that affect the reported amounts and disclosures in the financial
statements. Actual results may differ from those estimates.

1. SECURITY VALUATION: Equity securities listed on a U.S. exchange are valued at
   the latest quoted sales price on the valuation date. Equity securities listed
   or traded on NAS-DAQ, for which market quotations are available, are valued
   at the NASDAQ Official Closing Price. Securities listed on a foreign exchange
   are valued at their closing price. Unlisted and listed equity securities not
   traded on the valuation date, for which market quotations are readily
   available, are valued at the mean between the current bid and asked prices
   obtained from reputable brokers. Bonds and other fixed income securities may
   be valued according to the broadest and most representative market. In
   addition, bonds and other fixed income securities may be valued on the basis
   of prices provided by a pricing service. The prices provided by a pricing
   service take into account broker dealer market price quotations for
   institutional size trading in similar groups of securities, security quality,
   maturity, coupon and other security characteristics as well as any
   developments related to the specific security. Debt securities purchased with
   remaining maturities of 60 days or less are valued at amortized cost, if it
   approximates market value.

   All other securities and investments for which market values are not readily
   available, including restricted securities, and those securities for which it
   is inappropriate to determine prices in accordance with the aforementioned
   procedures, are valued at fair value as determined in good faith under
   procedures adopted by the Board of Trustees, although the actual calculations
   may be done by others. Factors considered in making this determination may
   include, but are not limited to, information obtained by contacting the
   issuer, analysts, or the appropriate stock exchange (for exchange-traded
   securities), analysis of the issuer's financial statements or other available
   documents and, if necessary, available information concerning other
   securities in similar circumstances.

   Most foreign markets close before the New York Stock Exchange (NYSE).
   Occasionally, developments that could affect the closing prices of securities
   and other assets may occur between the times at which valuations of such
   securities are determined (that is, close of the foreign market on which the
   securities trade) and the close of business on the NYSE. If these
   developments are expected to materially affect the value as of the
   securities, the valuations may be adjusted to reflect the estimated fair
   value as of the close of the NYSE, as determined in good faith under
   procedures established by the Board of Trustees.

2. REPURCHASE AGREEMENTS: Each Portfolio may enter into repurchase agreements
   under which a Portfolio lends excess cash and takes possession of securities
   with an agreement that the counterparty will repurchase such securities. In
   connection with transactions in repurchase agreements, a bank as custodian
   for the Fund takes possession of the underlying securities which are held as
   collateral, with a market value at least equal to the amount of the
   repurchase transaction, including principal and accrued interest. To the
   extent that any repurchase transaction exceeds one business day, the value of
   the of the collateral is marked-to-market on a daily basis to determine the
   adequacy of the collateral. In the event of default on the obligation to
   repurchase, the Fund has the right to liquidate the collateral and apply the
   proceeds in satisfaction of the obligation. In the event of default or
   bankruptcy by the counterparty to the agreement, realization and/or retention
   of the collateral or proceeds may be subject to legal proceedings.

   Pursuant to an exemptive order issued by the Securities and Exchange
   Commission, the Portfolios may transfer their uninvested cash balances into a
   joint trading account with other Portfolios of the Fund which invests in one
   or more repurchase agreements. Any such joint repurchase agreement is covered
   by the same collateral requirements as discussed above.

                                                                              85

NOTES TO FINANCIAL STATEMENTS (CONT'D)

3. FUTURES: Financial futures contracts (secured by cash and securities
   deposited with brokers as "initial margin") are valued based upon their
   quoted daily settlement prices; changes in initial settlement value
   (represented by cash paid to or received from brokers as "variation margin")
   are accounted for as unrealized appreciation (depreciation). When futures
   contracts are closed, the difference between the opening value at the date of
   purchase and the value at closing is recorded as realized gain or loss in the
   Statement of Operations. "Due from (to) Broker" includes initial margin and
   variation margin, as stated in the Statement of Net Assets.

   Futures contracts may be used by each Portfolio, except the Cash Reserves
   Portfolio, in order to hedge against unfavorable changes in the value of
   securities or to attempt to realize profits from the value of the related
   securities.

   Futures contracts involve market risk that may exceed the amounts recognized
   in the Statement of Net Assets. Risks arise from the possible movements in
   the prices of securities relating to these instruments. The change in value
   of futures contracts primarily corresponds with the value of their related
   securities, but may not precisely correlate with the change in value of such
   securities. In addition, there is the risk that a Portfolio may not be able
   to enter into a closing transaction because of an illiquid secondary market.

4. SECURITIES SOLD SHORT: Each Portfolio, except Cash Reserves Portfolio, may
   sell securities short. A short sale is a transaction in which the Portfolio
   sells securities it may or may not own, but has borrowed, in anticipation of
   a decline in the market price of the securities. The Portfolio is obligated
   to replace the borrowed securities at their market price at the time of
   replacement. The Portfolio may have to pay a premium to borrow the securities
   as well as pay any dividends or interest payable on the securities until they
   are replaced. The Portfolio's obligation to replace the securities borrowed
   in connection with a short sale will generally be secured by collateral
   deposited with the broker that consists of cash, U.S. government securities
   or other liquid high grade debt obligations. In addition, the Portfolio will
   either place in a segregated account with its custodian or denote on its
   custody records an amount of cash, U.S. government securities or other liquid
   high grade debt obligations equal to the difference, if any, between (1) the
   market value of the securities sold at the time they were sold short and (2)
   any cash, U.S. government securities or other liquid high grade debt
   obligations deposited as collateral with the broker in connection with the
   short sale (not including the proceeds of the short sale). Short sales by the
   Portfolios involve certain risks and special considerations. Possible losses
   from short sales differ from losses that could be incurred from a purchase of
   a security because losses from short sales may be unlimited, whereas losses
   from purchases cannot exceed the total amount invested.

5. SWAP AGREEMENTS: Each Portfolio, except the Cash Reserves Portfolio, may
   enter into swap agreements to exchange the interest rate on, or return
   generated by, one nominal instrument for the return generated by another
   nominal instrument. Cash collateral for swap agreements, if applicable, is
   deposited with the broker serving as counterparty to the agreement, and is
   included in "Due from (to) Broker" on the Statement of Net Assets. The
   following summarizes swaps entered into by the Portfolios:

   CREDIT DEFAULT SWAPS: Credit default swaps involve commitments to pay a fixed
   rate in exchange for payment if a credit event affecting a third party (the
   referenced company) occurs. Credit events may include a failure to pay
   interest, bankruptcy, or restructuring. Net periodic interest payments to be
   received or paid are accrued daily and are recorded in the Statement of
   Operations as an adjustment to interest income. Credit default swaps are
   marked-to-market daily based upon quotations from market makers and the
   change, if any, is recorded as unrealized appreciation or depreciation in the
   Statement of Operations.

   INTEREST RATE SWAPS: Interest rate swaps involve the exchange of commitments
   to pay and receive interest based on a notional principal amount. Net
   periodic interest payments to be received or paid are accrued daily and are
   recorded in the Statement of Operations as an adjustment to interest income.
   In a zero-coupon interest rate swap, payments only occur at maturity, at
   which time one counterparty pays the total compounded fixed rate over the
   life of the swap and the other pays the total compounded floating rate that
   would have been earned had a series of LIBOR investments been rolled over
   through the life of the swap. Interest rate swaps are marked-to-market daily
   based upon quotations from market makers and the change, if any, is recorded
   as unrealized appreciation or depreciation in the Statement of Operations.

   TOTAL RETURN SWAPS: Total return swaps involve commitments to pay interest in
   exchange for a market-linked return based on a notional amount. To the extent
   the total return of the security or index underlying the transaction exceeds
   or falls short of the offsetting interest rate obligation, the Portfolio will
   receive a payment from or make a payment to the counterparty, respectively.
   Total return swaps are marked-to-market daily based upon quotations from
   market makers and the change, if any, is recorded as unrealized appreciation
   or depreciation in the Statement of Operations. Periodic payments received or

                                                  March 31, 2004 (unaudited)

NOTES TO FINANCIAL STATEMENTS (CONT'D)

   Realized gains or losses on maturity or termination of swaps are presented in
   the Statement of Operations. Because there is no organized market for these
   swap agreements, the unrealized gain/loss reported in the Statement of Net
   Assets may differ from that which would be realized in the event the
   Portfolio terminated its position in the agreement. Risks may arise upon
   entering into these agreements from the potential inability of the
   counterparties to meet the terms of the agreements and are generally limited
   to the amount of net payments to be received, if any, at the date of default.

6. STRUCTURED INVESTMENTS: Certain Portfolios may invest in structured
   investments whose values are linked either directly or inversely to changes
   in foreign currencies, interest rates, commodities, indices, equity
   securities or other underlying instruments. A Portfolio uses these securities
   to increase or decrease its exposure to different underlying instruments and
   to gain exposure to markets that might be difficult to invest in through
   conventional securities. Structured investments may be more volatile than
   their underlying instruments, but any loss is limited to the amount of the
   original investment.

7. DELAYED DELIVERY COMMITMENTS: Each Portfolio, except the Cash Reserves
   Portfolio, may purchase or sell securities on a when-issued or forward
   commitment basis. Payment and delivery may take place a month or more after
   the date of the transaction. The price of the underlying securities and the
   date when the securities will be delivered and paid for are fixed at the time
   the transaction is negotiated. Liquid securities or cash is designated in an
   amount at least equal to these commitments. Securities held for this purpose
   cannot be sold while this strategy is outstanding, unless replaced with other
   assets. As a result, there is a possibility that as designated assets reach
   certain levels, a Portfolio may lose some flexibility in managing its
   investments, responding to shareholder redemption requests, or meeting other
   current obligations.

8. PURCHASED OPTIONS: Certain Portfolios may purchase call and put options on
   their portfolio securities. A call option, upon payment of a premium, gives
   the purchaser of the option the right to buy, and the writer the obligation
   to sell, the underlying instrument at the exercise price. The purchase of a
   call option might be intended to protect the Portfolio against an increase in
   the price of the underlying instrument that it intends to purchase in the
   future by fixing the price at which it may purchase the instrument. A put
   option gives the purchaser of the option, upon payment of a premium, the
   right to sell, and the writer the obligation to buy, the instrument at the
   exercise price. A Portfolio may purchase a put option to protect its holdings
   in the underlying instrument, or a similar instrument, against a substantial
   decline in the market value of such instrument by giving the Portfolio the
   right to sell the instrument at the option exercise price. Possible losses
   from purchased options cannot exceed the total amount invested.

9. FOREIGN CURRENCY TRANSLATION AND FOREIGN CURRENCY EXCHANGE CONTRACTS: The
   books and records of the Fund are maintained in U.S. dollars. Foreign
   currency amounts are translated into U.S. dollars at the bid prices of such
   currencies against U.S. dollars quoted by a bank. Net realized gains (losses)
   on foreign currency transactions represent net foreign exchange gains
   (losses) from foreign currency exchange contracts, disposition of foreign
   currencies, currency gains or losses realized between the trade and
   settlement dates on securities transactions, and the difference between the
   amount of investment income and foreign withholding taxes recorded on a
   Portfolio's books and the U.S. dollar equivalent of amounts actually received
   or paid.

   A foreign currency exchange contract is an agreement between two parties to
   buy or sell currency at a set price on a future date. Each Portfolio (except
   the U.S. Core Fixed Income, Cash Reserves, and Limited Duration Portfolios)
   may enter into foreign currency exchange contracts to protect securities and
   related receivables and payables against future changes in foreign exchange
   rates. Fluctuations in the value of such contracts are recorded as unrealized
   appreciation or depreciation; realized gains or losses, which are disclosed
   in the Statement of Operations, include net gains or losses on contracts
   which have been terminated by settlements. Risks may arise upon entering into
   these contracts from the potential inability of counterparties to meet the
   terms of their contracts and are generally limited to the amount of
   unrealized gain on the contract, if any, at the date of default. Risks may
   also arise from unanticipated movements in the value of the foreign currency
   relative to the U.S. dollar.

   At March 31, 2004, the net assets of certain Portfolios were substantially
   comprised of foreign-currency denominated securities and foreign currency.
   The net assets of these Portfolios are presented at the foreign exchange
   rates and market values at the close of the period. The Portfolios do not
   isolate that portion of the results of operations arising as a result of
   changes in the foreign exchange rates from the fluctuations arising from
   changes in the market prices of the securities held at period end. Similarly,
   the Portfolios do not isolate the effect of changes in foreign exchange rates
   from the fluctuations arising from changes in the market prices of securities
   sold during the period. Accordingly, the components of realized and
   unrealized foreign currency gains (losses) representing foreign exchange
   changes on investments is included in the reported net realized and
   unrealized gains (losses) on

                                                                              87

   investment transactions and balances. Changes in currency exchange rates will
   affect the value of and investment income from such securities and currency.

   Foreign security and currency transactions may involve certain considerations
   and risks not typically associated with those of U.S. dollar denominated
   transactions as a result of, among other factors, the possibly lower level of
   governmental supervision, relative currency valuation fluctuation, regulation
   of foreign securities markets and the possibility of political or economic
   instability.

10. OTHER: Security transactions are accounted for on the date the securities
   are purchased or sold. Costs used in determining realized gains and losses on
   the sale of investment securities are those of specific securities sold.
   Interest income is recognized on the accrual basis.

   Discounts and premiums on securities purchased are amortized over their
   respective lives. Most expenses of the Fund can be directly attributed to a
   particular Portfolio. Expenses which cannot be directly attributed are
   apportioned among the Portfolios on the basis of their relative net assets.
   Income, expenses (other than class specific expenses) and realized and
   unrealized gains or losses are allocated to each class of shares based upon
   their relative net assets.

B. INVESTMENT ADVISORY FEE. Under the terms of an Investment Advisory Agreement,
each Portfolio has agreed to pay Morgan Stanley Investment Management Inc. ("MS
Investment Management," formerly Morgan Stanley Investments LP, or the
"Adviser"), a wholly-owned subsidiary of Morgan Stanley, for investment advisory
services performed at a fee calculated by applying a quarterly rate based on the
annual percentage rate listed below, to each Portfolio's average daily net
assets for the quarter.

The Adviser has voluntarily agreed to reduce the fees payable to it and, if
necessary, reimburse the Portfolios for certain expenses so that annual
operating expenses, after giving effect to custody fee offsets, will not exceed
voluntary expense limitations established for each class of shares as presented
in the table above.

Morgan Stanley Investment Management Limited ("MSIM Limited") serves as
Sub-Adviser to the International Fixed Income Portfolio. MSIM Limited is a
wholly-owned subsidiary of Morgan Stanley. Under an Investment Sub-Advisory
Agreement with the Adviser, MSIM Limited, subject to the control and supervision
of the Fund, its officers, Trustees and the Adviser, and in accordance with the
investment objectives, policies and restrictions of the Portfolio, makes certain
day-to-day investment decisions for the Portfolio and places certain of the
Portfolio's purchase and sales orders. The Adviser pays MSIM Limited on a
monthly basis a portion of the net advisory fees the Adviser receives from the
Portfolio.

C. ADMINISTRATOR. MS Investment Management (the "Administrator") also provides
the Fund with administrative services pursuant to an administrative agreement
for a monthly fee which on an annual basis equals 0.08% of the average daily net
assets of each Portfolio, plus reimbursement of out-of-pocket expenses. Under an
agreement between the Administrator and J.P. Morgan Investor Services Co.
("JPMIS"), a corporate affiliate of JPMorgan Chase Bank, JPMIS provides certain
administrative services to the Fund. For such services, the Administrator pays
JPMIS a portion of the fee the Administrator receives from the Fund. An employee
of JPMIS is an officer of the Fund.

D. DISTRIBUTOR. Morgan Stanley Distribution, Inc. ("MSDI" or the "Distributor"),
a wholly-owned subsidiary of the Adviser, is the distributor for the Fund. MSDI
is a limited-purpose broker/dealer whose only function is to distribute open-end
mutual fund shares. The Distributor provides all classes of shares in each
Portfolio with distribution services, and receives fees in connection with these
services, pursuant to separate Distribution and Shareholder Servicing Plans (the
"Plans") in accordance with Rule 12b-1 under the Investment Company Act of 1940.

Under the Plans, the Distributor is entitled to distribution fees and
shareholder servicing fees for Adviser Class and Investment Class shares,
respectively. The distribution fee is an asset-based fee to support distribution
efforts and/or servicing of accounts. The Adviser Class of shares pays an annual
distribution fee of 0.25% of average net assets of the class for such services
under the 12b-1 plan adopted by the Fund. The Investment Class of shares pays an
annual shareholder servicing fee of 0.15% of average net assets of the class.
The shareholder servicing fee is used to support the expenses associated with
servicing and maintaining accounts. Both fees are paid directly to MSDI. The
distribution fee may be retained by MSDI if an Adviser Class shareholder invests
directly through

MSDI. Usually the fees are paid by MSDI to external organizations such as 401(k)
alliance sponsors, discount brokers and bank trust departments who distribute
MSIFT Portfolios to the public. The Distributor has voluntarily agreed to waive
0.10% of the 0.25% distribution fee it is entitled to receive from the Adviser
Class Shares' average daily net assets for the Investment Grade Fixed Income
Portfolio.

E. CUSTODY. JPMorgan Chase Bank serves as custodian for the Fund in accordance
with a custodian agreement. The Custodian holds cash, securities, and other
assets of the Fund as required by the 1940 Act.

The Portfolios have entered into an arrangement with their custodian whereby
credits realized on uninvested cash balances were used to offset a portion of
each applicable Portfolio's expenses. These custodian credits are shown as
"expense offset" on the Statements of Operations.

G. SECURITIES LENDING. Certain Portfolios may lend securities to qualified
financial institutions, such as broker-dealers, to earn additional income. Any
increase or decrease in the fair value of the securities loaned that might occur
and any interest earned or dividends declared on those securities during the
term of the loan would remain in the Portfolio. Portfolios that lend securities
receive cash or securities as collateral in an amount equal to or exceeding 100%
of the current fair value of the loaned securities. The collateral is marked to
market daily, by the securities lending agent, to ensure that a minimum of 100%
collateral coverage is maintained.

Based on pre-established guidelines, the securities lending agent invests any
cash collateral that is received in high-quality short-term investments. the
Portfolio retains a portion of the income derived from these investments, which
is included in the Statement of Operations in interest income. Risk in
securities lending transactions are that a borrower may not provide additional
collateral when required or return the securities when due, and that the value
of the short-term investments will be less than the amount of cash collateral
plus any rebate that is required to be returned to the borrower. The value of
loaned securities and related collateral outstanding at March 31, 2004 are as
follows:

H. FEDERAL INCOME TAXES. It is each Portfolio's intention to continue to qualify
as a regulated investment company and distribute all of its taxable income.
Accordingly, no provision for Federal income taxes is required in the financial
statements. Dividend income and distributions to shareholders are recorded on
the ex-dividend date. Interest income is recognized on the accrual basis.
Dividends from net investment income, if any, are declared and paid quarterly
except for those of the Cash Reserves Portfolio which are declared daily and

paid monthly and Intermediate Duration, Limited Duration and Municipal
Portfolios which are declared and paid monthly. Net realized capital gains are
distributed at least annually.

The tax character of the Municipal Portfolio's ordinary income distributions
include tax exempt as well as taxable components. The undistributed ordinary
income for the Municipal Portfolio includes tax exempt as well as taxable
components.

The tax character for distributions paid may differ from the character of
distributions shown on the Statement of Changes in Net Assets due to short-term
capital gains being treated as ordinary income for tax purposes. The tax
character of distributions paid during fiscal 2003 and 2002 were as follows:

</Table>

The amount and character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from accounting
principles generally accepted in the United States. The book/tax differences are
either considered temporary or permanent in nature. Temporary differences are
generally due to differing book and tax treatments in the timing of the
recognition of gains or losses on securities, forwards and futures, including
Post October losses. Permanent differences are generally due to REIT
adjustments, gain (loss) on in-kind redemptions, foreign currency transactions
and gains on certain equity securities designated as issued by "passive foreign
investment companies".

Permanent book and tax basis differences may result in reclassifications to
undistributed (distributions in excess of) net investment income and paid-in
capital.

At September 30, 2003, the components of distributable earnings on a tax basis
were as follows:

2004 SEMI-ANNUAL REPORT

March 31, 2004 (unaudited)

NOTES TO FINANCIAL STATEMENTS (CONT'D)

In addition to the $243,906,000 in unused capital losses attributed to the High
Yield Portfolio in the table above, approximately $63,437,000 has been brought
forward as a result of the Portfolio's merger with the MSIF High Yield II
Portfolio. The utilization of the capital loss carryforward in subsequent years
may be limited pursuant to sections 382 and 383 of the Internal Revenue Code.
This acquired capital loss carryforward is expected to expire between 2006-2011.

To the extent that capital loss carryover is used to offset any future capital
gains realized during the carryover period as provided by U.S. Federal income
tax regulations, no capital gains tax liability will be incurred by a portfolio
for gains realized and not distributed. To the extent that capital gains are
offset, such gains will not be distributed to the shareholders.

Under current tax law, certain capital and net foreign exchange losses realized
after October 31 may be deferred and treated as occurring on the first day of
the following fiscal year. For the fiscal year ended September 30, 2003, the
following Portfolios elected to defer capital and currency losses occurring
between November 1, 2002 and September 30, 2003 up to the following amounts:

I. OTHER. The High Yield Portfolio's net assets are substantially comprised of
high yield fixed income securities. The financial condition of an issuer of
these securities and general economic and industry specific conditions may
affect an issuer's ability to make payments of income and principal on these
securities and ultimately impact their valuation.

A portion of the securities of the Municipal Portfolio are insured by certain
companies specializing in the insurance of municipal debt obligations. At March
31, 2004, approximately 52.8% of the net assets of the Municipal Portfolio are
covered by such insurance. Listed below are the insurers that insure obligations
constituting more than 10% of the Portfolio's net assets:
