     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to decrease net investment income per share by
     $0.004, increase net realized and unrealized gains and losses per share by
     $0.004 and decrease the ratio of net investment income to average net
     assets from 6.37% to 6.35%. Per share data and ratios/supplemental data for

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                       STANDISH MELLON FIXED INCOME FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon Fixed Income Fund (the "Fund") is a separate diversified
     investment series of the Trust.

     The objective of the Fund is to achieve a high level of current income,
     consistent with conserving principal and liquidity, and secondarily to seek
     capital appreciation when changes in interest rates and economic conditions
     indicate that capital appreciation may be available without significant
     risk to principal. The Fund seeks to achieve its objective by investing all
     of its investable assets in an interest of the Standish Mellon Fixed Income
     Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds
     Master Portfolio (the "Portfolio Trust"), which is organized as a New York
     trust and which has the same investment objective as the Fund. The
     Portfolio seeks to achieve its objective by investing, under normal
     circumstances, at least 80% of net assets in fixed income securities issued
     by U.S. and foreign governments and companies. The value of the Fund's
     investment in the Portfolio reflects the Fund's proportionate interest in
     the net assets of the Portfolio (approximately 100% at June 30, 2004). The
     performance of the Fund is directly affected by the performance of the
     Portfolio. The financial statements of the Portfolio are included elsewhere
     in this report and should be read in conjunction with the Fund's financial
     statements.

     The following is a summary of significant accounting policies followed by
     the Fund in the preparation of its financial statements. The preparation of
     financial statements in accordance with accounting principles generally
     accepted in the United States of America requires management to make
     estimates and assumptions that affect the reported amounts and disclosures
     in the financial statements. Actual results could differ from those
     estimates.

     A. INVESTMENT SECURITY VALUATIONS

     The Fund records its investment in the Portfolio at value. The method by
     which the Portfolio values its securities is discussed in Note 1A of the
     Portfolio's Notes to Financial Statements, which are included elsewhere in
     this report.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Currently, the
     Fund's net investment income consists of the Fund's pro rata share of the
     net investment income of the Portfolio, less all actual and accrued
     expenses of the Fund determined in accordance with generally accepted
     accounting principles. All realized and unrealized gains and losses of the
     Portfolio are allocated pro rata among the investors in the Portfolio. The
     Fund does not isolate that portion of the results of operations resulting
     from changes in foreign exchange rates on investments from the fluctuations
     arising from changes in market prices of securities held. Such fluctuations
     are included with the net realized and unrealized gain or loss from
     investments.

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. In determining the amounts of its dividends,
     the Fund will take into account its share of the income, gains or losses,
     expenses, and any other tax items of the Portfolio. Dividends from net
     investment income and distributions from capital gains, if any, are
     reinvested in additional shares of the Fund unless a shareholder elects to
     receive them in cash. Income and capital gain distributions are determined
     in accordance with income tax regulations which may differ from generally
     accepted accounting principles. These differences, which may result in
     distribution reclassifications, are primarily due to differing treatments
     for foreign currency transactions, options, futures, interest rate floor,
     capital loss carryforwards, losses deferred due to wash sales, paydown
     gains and losses, and amortization and/or accretion of premiums and
     discounts on certain securities.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications to undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments and foreign currency transactions may include
     temporary book and tax basis differences which will reverse in a subsequent
     period. Any taxable income or gain remaining at fiscal year end is
     distributed in the following year.

     D. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expense and the relative size of the funds.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     E. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Fund may enter into contracts and
     agreements that contain a variety of representations and warranties, which
     provide general indemnifications. The maximum exposure to the Fund under
     these arrangements is unknown, as this would involve future claims that may
     be made against the Fund that have not yet occurred. However, based on
     experience, the Fund expects the risks of loss to be remote.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary of Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report.

     On February 23, 2004, the Fund entered into an agreement with Dreyfus
     Transfer, Inc., a wholly-owned subsidiary of Dreyfus, which is an affiliate
     of Standish Mellon, to provide transfer agent services to the Fund.
     Pursuant to this agreement the Fund was charged $2,079 during the period
     ended June 30, 2004. At June 30, 2004, $2,079 was due to Dreyfus Transfer,
     Inc.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     period ended June 30, 2004, aggregated $34,100,503 and $178,729,348
     respectively.

(4)  SHARES OF BENEFICIAL INTEREST:

     The Declaration of Trust permits the Trustees to issue an unlimited number
     of full and fractional shares of beneficial interest having a par value of
     one cent per share. Transactions in Fund shares were as follows:



                                                              PERIOD ENDED

     At June 30, 2004, one shareholder of record held approximately 13% of the
     total outstanding shares of the Fund. Investment activity of this
     shareholder could have a material impact on the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

                     STANDISH MELLON FIXED INCOME PORTFOLIO

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
     organized as a master trust fund under the laws of the state of New York on
     January 18, 1996 and is registered under the Investment Company Act of
     1940, as amended, as an open-end, management investment company. Standish
     Mellon Fixed Income Portfolio (the "Portfolio") is a separate diversified
     investment series of the Portfolio Trust.

     At June 30, 2004, there was one fund, Standish Mellon Fixed Income Fund
     (the "Fund"), invested in the Portfolio. The value of the Fund's investment
     in the Portfolio reflects the Fund's proportionate interest in the net
     assets of the Portfolio. The Fund's proportionate interest at June 30, 2004
     was approximately 100%.

     The objective of the Portfolio is to achieve a high level of current
     income, consistent with conserving principal and liquidity, and secondarily
     to seek capital appreciation when changes in interest rates and economic
     conditions indicate that capital appreciation may be available without
     significant risk to principal by investing, under normal circumstances, at
     least 80% of net assets in fixed income securities issued by U.S. and
     foreign governments and companies.

     The following is a summary of significant accounting policies followed by
     the Portfolio in the preparation of its financial statements. The
     preparation of financial statements in accordance with accounting
     principles generally accepted in the United States of America requires
     management to make estimates and assumptions that affect the reported
     amounts and disclosures in the financial statements. Actual results could
     differ from those estimates.

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are normally traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     when acquired by the Portfolio are valued at amortized cost, which
     approximates market value. If the Portfolio acquires a short-term
     instrument with more than sixty days remaining to its maturity, it is
     valued at current market value until the sixtieth day prior to maturity and
     will then be valued at amortized value based upon the value on such date
     unless the Trustees determine during such sixty-day period that amortized
     value does not represent fair value.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method on
     long-term debt securities. Dividend income is recorded on the ex-dividend
     date. Realized gains and losses from securities sold are recorded on the
     identified cost basis. The Portfolio does not isolate that portion of the
     results of operations resulting from changes in foreign exchange rates on
     investments from the fluctuations arising from changes in market prices of
     securities held. Such fluctuations are included with the net realized and
     unrealized gain or loss from investments. Net realized gains and losses on
     foreign currency transactions represent gains and losses on disposition of
     foreign currencies and forward foreign currency exchange contracts,
     currency gains and 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 the Fund's
     books and the U.S. dollar equivalent amounts usually received or paid.

     C. INCOME TAXES

     The Portfolio is treated as a partnership for federal tax purposes. No
     provision is made by the Portfolio for federal or state taxes on any
     taxable income of the Portfolio because each investor in the Portfolio is
     ultimately responsible for the payment of any taxes. Since at least one of
     the Portfolio's investors is a regulated investment company that invests
     all or substantially all of its assets in the Portfolio, the Portfolio
     normally must satisfy the source of income and diversification requirements
     applicable to regulated investment companies (under the Internal Revenue
     Code) in order for its investors to satisfy them. The Portfolio allocates
     at least annually among its investors each investor's distributive share of
     the Portfolio's net investment income, net realized capital gains, and any
     other items of income, gain, loss deduction or credit.

     D. FOREIGN CURRENCY TRANSACTIONS

     Investment security valuations, other assets, and liabilities initially
     expressed in foreign currencies are converted into U.S. dollars based upon
     current currency exchange rates. Purchases and sales of foreign investment
     securities and income and expenses are converted into U.S. dollars based
     upon currency exchange rates prevailing on the respective dates of such
     transactions.

     Section 988 of the Internal Revenue Code provides that gains or losses on
     certain transactions attributable to fluctuations in foreign currency
     exchange rates must be treated as ordinary income or loss. For financial
     statement purposes, such amounts are included in net realized gains or
     losses.

     E. INVESTMENT RISK

     There are certain additional risks involved in investing in foreign
     securities that are not inherent in investments in domestic securities.
     These risks may involve adverse political and economic developments,
     including the possible imposition of capital controls or other foreign
     governmental laws or restrictions. In addition, the securities of some
     foreign companies and securities markets are less liquid and at times may
     be more volatile than securities of comparable U.S. companies and U.S.
     securities markets. The risks described above apply to an even greater
     extent to investments in emerging markets. The securities markets of
     emerging countries are generally smaller, less developed, less liquid, and
     more volatile than the securities markets of the U.S. and developed foreign
     markets.

     F. COMMITMENT AND CONTINGENCIES

     In the normal course of business, the Portfolio may enter into contracts
     and agreements that contain a variety of representations and warranties,
     which provide general indemnifications. The maximum exposure to the
     Portfolio under these arrangements is unknown, as this would involve future
     claims that may be made against the Portfolio that have not yet occurred.
     However, based on experience, the Portfolio expects the risks of loss to be
     remote.

     G. AFFILIATED ISSUERS

     Issuers in which the Portfolio held investments in other investment
     companies advised by Standish Mellon Asset Management Company LLC
     ("Standish Mellon") or its affiliates.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services is paid monthly at the annual rate of
     0.40% of the Portfolio's first $250,000,000 of average daily net assets,
     0.35% of the next $250,000,000 of average daily net assets, and 0.30% of
     the average daily net assets in excess of $500,000,000.

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio was charged $88,461 during the period ended
     June 30, 2004 and owed $29,000.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the Trustees.

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the period ended June 30, 2004 were as follows:

                                                    ============


(5)  FINANCIAL INSTRUMENTS:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved. The
     nature, risks and objectives of these instruments are set forth more fully
     in the Portfolio Trust's registration statement.

     The Portfolio may trade the following financial instruments with
     off-balance sheet risk:

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Portfolio may use options to seek to hedge against
     risks of market exposure and changes in security prices and foreign
     currencies, as well as to seek to enhance returns. Writing puts and buying
     calls tend to increase the Portfolio's exposure to the underlying
     instrument. Buying puts and writing calls tend to decrease the Portfolio's
     exposure to the underlying instrument, or hedge other Portfolio
     investments. Options, both held and written by the Portfolio, are reflected
     in the accompanying Statement of Assets and Liabilities at market value.
     The underlying face amount at value of any open purchased options is shown
     in the Schedule of Investments. This amount reflects each contract's
     exposure to the underlying instrument at period end. Losses may arise from
     changes in the value of the underlying instruments if there is an illiquid
     secondary market for the contract or if the counterparty does not perform
     under the contract's terms.

     Premiums received from writing options which expire are treated as realized
     gains. Premiums received from writing options which are exercised or are
     closed are added to or offset against the proceeds or amount paid on the
     transaction to determine the realized gain or loss. Realized gains and
     losses on purchased options are included in realized gains and losses on
     investment securities, except purchased options on foreign currency which
     are included in realized gains and losses on foreign currency transactions.
     If a put option written by the Portfolio is exercised, the premium reduces
     the cost basis of the securities purchased by the Portfolio. The Portfolio,
     as a writer of an option, has no control over whether the underlying
     securities may be sold (call) or purchased (put) and as a result bears the
     market risk of an unfavorable change in the price of the security
     underlying the written option.

     Exchange traded options are valued at the last sale price, or if no sales
     are reported, the last bid price for purchased options and the last ask
     price for written options. Options traded over-the-counter are valued using
     prices supplied by the dealers.

     A summary of the written put options for the period ended June 30, 2004 is
     as follows:

     INTEREST RATE FLOORS

     Interest rate floors purchased by the Portfolio entitle the Portfolio to
     receive payments on a notional principal amount from the party selling such
     floor to the extent that a specified index falls below a predetermined
     interest rate amount. Credit and market risk exist with respect to these
     instruments. If forecasts of interest rates and other market factors are
     incorrect, investment performance will diminish compared to what
     performance would have been if these investment techniques were not used.
     Even if the forecasts are correct, there are risks that the positions may
     correlate imperfectly with the asset or liability being hedged, a liquid
     secondary market may not always exist, or counterparty to a transaction may
     not perform. The Portfolio expects to enter these transactions primarily
     for hedging purposes including, but not limited to, preserving a return or
     spread on a particular investment or portion of its portfolio, protecting
     against currency fluctuations, as a duration management technique or
     protecting against an increase in the price of securities the Portfolio
     anticipates purchasing at a later date. Interest rate floors are
     "marked-to-market" daily based on quotations from market makers and the
     change, if any, is recorded as unrealized appreciation or depreciation in
     the Statement of Operations. Periodic payments of interest, if any, are
     reported as additions to interest income in the Statement of Operations.
     Realized gains or losses from these agreements are disclosed in the
     Statement of Operations.

     At June 30, 2004, the Portfolio did not hold any open interest rate floor
     agreements.

     FORWARD CURRENCY EXCHANGE CONTRACTS

     The Portfolio may enter into forward foreign currency and cross currency
     exchange contracts for the purchase or sale of a specific foreign currency
     at a fixed price on a future date. Risks may arise upon entering these
     contracts from the potential inability of counterparties to meet the terms
     of their contracts and from unanticipated movements in the value of a
     foreign currency relative to the U.S. dollar and other foreign currencies.
     The forward foreign currency and cross currency exchange contracts are
     marked to market using the forward foreign currency rate of the underlying
     currency and any gains or losses are recorded for financial statement
     purposes as unrealized until the contract settlement date or upon the
     closing of the contract. Forward currency exchange contracts are used by
     the Portfolio primarily to protect the value of the Portfolio's foreign
     securities from adverse currency movements. Unrealized appreciation and
     depreciation of forward currency exchange contracts is included in the
     Statement of Assets and Liabilities.

     At June 30, 2004, the Portfolio held the following forward foreign currency
     exchange contracts:

     FUTURES CONTRACTS

     The Portfolio may enter into financial futures contracts for the delayed
     sale or delivery of securities or contracts based on financial indices at a
     fixed price on a future date. Pursuant to margin requirements the Portfolio
     deposits either cash or securities in an amount equal to a certain
     percentage of the contract amount. Subsequent payments are made or received
     by the Portfolio each day, depending on the daily fluctuations in the value
     of the underlying security, and are recorded for financial statement
     purposes as unrealized gains or losses by the Portfolio. There are several
     risks in connection with the use of futures contracts as a hedging device.
     The change in value of futures contracts primarily corresponds with the
     value of their underlying instruments or indices, which may not correlate
     with changes in the value of hedged investments. Buying futures tends to
     increase the Portfolio's exposure to the underlying instrument, while
     selling futures tends to decrease the Portfolio's exposure to the
     underlying instrument or hedge other investments. In addition, there is the
     risk that the Portfolio may not be able to enter into a closing transaction
     because of an illiquid secondary market. Losses may arise if there is an
     illiquid secondary market or if the counterparty does not perform under the
     contract's terms. The Portfolio enters into financial futures transactions
     primarily to seek to manage its exposure to certain markets and to changes
     in securities prices and foreign currencies. Gains and losses are realized
     upon the expiration or closing of the futures contracts. Futures contracts
     are valued at the quoted daily settlement prices established by the
     exchange on which they trade.

     At June 30, 2004, the Portfolio held the following financials futures
     contracts:

     SWAP AGREEMENTS

     The Portfolio may enter into swap agreements. A swap is an agreement to
     exchange the return generated by one instrument for the return generated by
     another instrument. The Portfolio may enter into interest rate and credit
     default swap agreements to manage its exposure to interest rates and credit
     risk. Interest rate swap agreements involve the exchange by the Portfolio
     with another party of their respective commitments to pay or receive
     interest, e.g., an exchange of floating rate payments for fixed rate
     payments with respect to a notional amount of principal. In a credit
     default swap, one party makes a stream of payments to another party in
     exchange for the right to receive a specified return in the event of a
     default by a third party on its obligation. The Portfolio may use credit
     default swaps to provide a measure of protection against defaults of
     issuers (i.e., to reduce risk where the Portfolio owns or has exposure to
     the corporate or sovereign issuer) or to take an active long or short
     position with respect to the likelihood of a particular corporate or
     sovereign issuer's default. In connection with these agreements, cash or
     securities may be set aside as collateral in accordance with the terms of
     the swap agreement. The Portfolio earns interest on cash set aside as
     collateral. Swaps are marked to market daily based upon quotations from
     market makers and change in value, if any, is recorded as unrealized gain
     or loss in the Statement of Operations. These financial instruments are not
     actively traded on financial markets. The values assigned to these
     instruments are based upon the best available information and because of
     the uncertainty of the valuation, these values may differ significantly
     from the values that would have been realized had a ready market for these
     instruments existed, and differences could be material. Payments received
     or made from credit default swaps at the end of the measurement period are
     recorded as realized gain or loss in the Statement of Operations. Net
     payments of interest on interest rate swap agreements, if any, are included
     as part of realized gain or loss. Entering into these agreements involves,
     to varying degrees, elements of credit, market, and documentation risk in
     excess of the amounts recognized on the Statement of Assets and
     Liabilities. Such risks involve the possibility that there will be no
     liquid market for these agreements, that the counterparty to the agreements
     may default on its obligation to perform or disagree as to the meaning of
     contractual terms in the agreements, and that there may be unfavorable
     changes in interest rates.

(6)  DELAYED DELIVERY TRANSACTIONS:

     The Portfolio may purchase or sell securities on a when-issued, delayed
     delivery or forward commitment basis. Payment and delivery may take place a
     month or more after the date of the transactions. 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. Income on
     the securities will not be earned until settlement date. The Portfolio
     instructs its custodian to segregate securities having value at least equal
     to the amount of the purchase commitment.

     The Portfolio may enter into to be announced ("TBA") purchase commitments
     to purchase securities for a fixed unit price at a future date beyond
     customary settlement time. Although the unit price has been established,
     the principal value has not been finalized. However, the amount of the
     commitments will not fluctuate more than 0.01% from the principal amount.
     The Portfolio holds, and maintains until settlement date, cash or
     high-grade debt obligations in an amount sufficient to meet the purchase
     price, or the Portfolio may enter into offsetting contracts for the forward
     sale of other securities it owns. Income on the securities will not be
     earned until settlement date. TBA purchase commitments may be considered
     securities in themselves, and involve a risk of loss if the value of the
     security to be purchased declines prior to the settlement date, which risk
     is in addition to the risk of decline in the value of the Portfolio's other
     assets. Unsettled TBA purchase commitments are valued at the current market
     value of the underlying securities, according to the procedures described
     under "Investment security valuations" above.

     The Portfolio may enter into TBA sale commitments to hedge its portfolio
     positions. Proceeds of TBA sale commitments are not received until the
     contractual settlement date. During the time a TBA sale commitment is
     outstanding, an offsetting TBA purchase commitment deliverable is held as
     "cover" for the transaction.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     "marked-to-market" daily and the change in market value is recorded by the
     Portfolio as an unrealized gain or loss. If the TBA sale commitment is
     closed through the acquisition of an offsetting purchase commitment, the
     Portfolio realizes a gain or loss. If the Portfolio delivers securities
     under the commitment, the Portfolio realizes a gain or a loss from the sale
     of the securities based upon the unit price established at the date the
     commitment was entered into.

     See the Schedule of Investments for outstanding delayed delivery
     transactions.

(7)  SECURITIES LENDING:

     The Portfolio may lend its securities to financial institutions which the
     Portfolio deems to be creditworthy. The loans are collateralized at all
     times with cash or securities with a market value at least equal to the
     market value of the securities on loan. The market value of securities
     loaned is determined daily and any additional required collateral is
     allocated to the Portfolio on the next business day. For the duration of a
     loan, the Portfolio receives the equivalent of the interest or dividends
     paid by the issuer on the securities loaned and also receives compensation
     from the investment of the collateral. As with other extensions of credit,
     the Portfolio bears the risk of delay in recovery or even loss of rights in
     its securities on loan should the borrower of the securities fail
     financially or default on its obligations to the Portfolio. In the event of
     borrower default, the Portfolio generally has the right to use the
     collateral to offset losses incurred. The Portfolio may incur a loss in the
     event it was delayed or prevented from exercising its rights to dispose of
     the collateral. The Portfolio also bears the risk in the event that the
     interest and/or dividends received on invested collateral is not sufficient
     to meet the Portfolio's obligations due on the loans.

     The Portfolio loaned securities during the period ended June 30, 2004
     resulting in $30,662 of security lending income. At June 30, 2004, the
     Portfolio had $33,191,879 worth of securities on loan.

     See the Schedule of Investments for securities on loan.

(8)  LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
     Trust are parties to a committed line of credit facility, which enables
     each portfolio/fund to borrow, in the aggregate, up to $35 million.
     Interest is charged to each participating portfolio/fund based on its
     borrowings at a rate equal to the Federal Funds effective rate plus 1-2 of
     1%. In addition, a commitment fee, computed at an annual rate of 0.060 of
     1% on the daily unused portion of the facility, is allocated ratably among
     the participating portfolios/funds at the end of each quarter.

     For the period ended June 30, 2004, the expense related to the commitment
     fee was $2,117 for the Portfolio.

     During the period ended June 30, 2004, the Portfolio had not borrowed under
     the credit facility.

(a)  Through its investment in the Portfolio, the Fund has adopted the
     provisions of the revised AICPA Audit and Accounting Guide for Investment
     Companies effective January 1, 2001 and began amortizing premium and
     discount on all debt securities on an effective yield basis. The effect of
     this change for the year ended December 31, 2001 was to decrease net
     investment income per share by $0.007, increase net realized and unrealized
     gains and losses per share by $0.007 and decrease the ratio of net
     investment income to average net assets from 4.50% to 4.46%. Per share data

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                    STANDISH MELLON GLOBAL FIXED INCOME FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon Global Fixed Income Fund (the "Fund") is a separate
     non-diversified investment series of the Trust.

     The objective of the Fund is to maximize total return while realizing a
     market level of income consistent with preserving principal and liquidity.
     The Fund seeks to achieve its objective by investing all of its investable
     assets in an interest of Standish Mellon Global Fixed Income Portfolio (the
     "Portfolio"), a subtrust of the Mellon Institutional Funds Master Portfolio
     (the "Portfolio Trust"), which is organized as a New York trust and which
     has the same investment objective as the Fund. The Portfolio seeks to
     achieve its investment objective by investing, under normal circumstances,
     at least 80% of its net assets in U.S. and non-U.S. dollar denominated
     fixed income securities of U.S. and foreign governments and companies
     located in the U.S. and various countries, including emerging markets. The
     value of the Fund's investment in the Portfolio reflects the Fund's
     proportionate interest in the net assets of the Portfolio (approximately
     100% at June 30, 2004). The performance of the Fund is directly affected by
     the performance of the Portfolio. The financial statements of the Portfolio
     are included elsewhere in this report and should be read in conjunction
     with the Fund's financial statements.

     The following is a summary of significant accounting policies followed by
     the Fund in the preparation of its financial statements. The preparation of
     financial statements in accordance with accounting principles generally
     accepted in the United States of America requires management to make
     estimates and assumptions that affect the reported amounts and disclosures
     in the financial statements. Actual results could differ from those
     estimates.

     A. INVESTMENT SECURITY VALUATIONS

     The Fund records its investment in the Portfolio at value. The method by
     which the Portfolio values its securities is discussed in Note 1A of the
     Portfolio's Notes to Financial Statements, which are included elsewhere in
     this report.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Currently, the
     Fund's net investment income consists of the Fund's pro rata share of the
     net investment income of the Portfolio, less all actual and accrued
     expenses of the Fund determined in accordance with accounting principles
     generally accepted in the United States of America. All realized and
     unrealized gains and losses of the Portfolio are allocated pro rata among
     the investors in the Portfolio. The Fund does not isolate that portion of
     the results of operations resulting from changes in foreign exchange rates
     on investments from the fluctuations arising from changes in market prices
     of securities held. Such fluctuations are included with the net realized
     and unrealized gain or loss from investments.

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. In determining the amounts of its dividends,
     the Fund will take into account its share of the income, gains or losses,
     expenses, and any other tax items of the Portfolio. Distributions to
     shareholders are recorded on ex-dividend date. Dividends from net
     investment income and distributions from capital gains, if any, are
     reinvested in additional shares of the Fund unless a shareholder elects to
     receive them in cash. Income and capital gain distributions are determined
     in accordance with income tax regulations which may differ from accounting
     principles generally accepted in the United States of America. These
     differences, which may result in distribution reclassifications, are
     primarily due to differing treatments for foreign currency transactions,
     options, futures, amortization and/or accretion of premiums and discounts
     on certain securities, capital loss carryforwards and losses deferred due
     to wash sales.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications to undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments and foreign currency transactions may include
     temporary book and tax basis differences which will reverse in a subsequent
     period. Any taxable income or gain remaining at fiscal year end is
     distributed in the following year.

     D. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expense and the relative size of the funds.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     E. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Fund may enter into contracts and
     agreements that contain a variety of representations and warranties, which
     provide general indemnifications. The maximum exposure to the Fund under
     these arrangements is unknown, as this would involve future claims that may
     be made against the Fund that have not yet occurred. However, based on
     experience, the Fund expects the risks of loss to be remote.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary of Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report.

     On February 23, 2004, the Fund entered into an agreement with Dreyfus
     Transfer, Inc., a wholly owned subsidiary of Dreyfus, which is an affiliate
     of Standish Mellon, to provide transfer agent services to the Fund.
     Pursuant to this agreement the Fund was charged $2,391 during the period
     ended June 30, 2004 and $2,391 was owed at June 30, 2004.

     The Portfolio compensates Mellon Bank, N.A. under a administration and
     accounting services agreement for providing fund administration and fund
     accounting services for the Portfolio.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     period ended June 30, 2004, aggregated $1,941,448 and $65,926,424,
     respectively.

(4)  SHARES OF BENEFICIAL INTEREST:

     The Declaration of Trust permits the Trustees to issue an unlimited number
     of full and fractional shares of beneficial interest having a par value of
     one cent per share. Transactions in Fund shares were as follows:

     At June 30, 2004, three shareholders of record held approximately 31%, 21%
     and 19% of the total outstanding shares of the Fund, respectively.
     Investment activity of these shareholders could have a material impact on
     the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

       Accounting Guide for Investment Companies effective January 1, 2001 and
       began amortizing premium and discount on all debt securities on an
       effective yield basis. The effect of this change for the year ended
       December 31, 2001 was to decrease the ratio of the net investment income
       to average net assets from 4.53% to 4.49%. Ratios for the periods prior

                  STANDISH MELLON GLOBAL FIXED INCOME PORTFOLIO

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
     organized as a master trust fund under the laws of the state of New York on
     January 18, 1996 and is registered under the Investment Company Act of
     1940, as amended, as an open-end, management investment company. Standish
     Mellon Global Fixed Income Portfolio (the "Portfolio") is a separate
     non-diversified investment series of the Portfolio Trust.

     The objective of the Portfolio is to maximize total return while realizing
     a market level of income consistent with preserving principal and
     liquidity. The Portfolio seeks to achieve its objective by investing, under
     normal circumstances, at least 80% of its net assets in U.S. and non-U.S.
     dollar denominated fixed income securities of U.S. and foreign governments
     and companies located in the U.S. and various countries, including emerging
     markets.

     At June 30, 2004 there was one fund, Standish Mellon Global Fixed Income
     Fund (the "Fund"), invested in the Portfolio. The value of the Fund's
     investment in the Portfolio reflects the Fund's proportionate interest in
     the net assets of the Portfolio. The Fund's proportionate interest at June
     30, 2004 was approximately 100%.

     The following is a summary of significant accounting policies followed by
     the Portfolio in the preparation of its financial statements. The
     preparation of financial statements in accordance with accounting
     principles generally accepted in the United States of America requires
     management to make estimates and assumptions that affect the reported
     amounts and disclosures in the financial statements. Actual results could
     differ from those estimates.

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are normally traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     when acquired by the Portfolio are valued at amortized cost, which
     approximates market value. If the Portfolio acquires a short-term
     instrument with more than sixty days remaining to its maturity, it is
     valued at current market value until the sixtieth day prior to maturity and
     will then be valued at amortized value based upon the value on such date
     unless the Trustees determine during such sixty-day period that amortized
     value does not represent fair value.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield - to - maturity method
     on long-term debt securities. Realized gains and losses from securities
     sold are recorded on the identified cost basis. The Portfolio does not
     isolate that portion of the results of operations resulting from changes in
     foreign exchange rates on investments from the fluctuations arising from
     changes in market prices of securities held. Such fluctuations are included
     with the net realized and unrealized gain or loss from investments. Net
     realized gains and losses on foreign currency transactions represent gains
     and losses on disposition of foreign currencies and forward foreign
     currency exchange contracts, currency gains and 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 the Fund's books and the U.S. dollar equivalent amounts usually
     required or paid.

     C. INCOME TAXES

     The Portfolio is treated as a partnership for federal tax purposes. No
     provision is made by the Portfolio for federal or state taxes on any
     taxable income of the Portfolio because each investor in the Portfolio is
     ultimately responsible for the payment of any taxes. Since at least one of
     the Portfolio's investors is a regulated investment company that invests
     all or substantially all of its assets in the Portfolio, the Portfolio
     normally must satisfy the source of income and diversification requirements
     applicable to regulated investment companies (under the Internal Revenue
     Code) in order for its investors to satisfy them. The Portfolio allocates
     at least annually among its investors each investor's distributive share of
     the Portfolio's net investment income, net realized capital gains, and any
     other items of income, gain, loss deduction or credit.

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

     D. FOREIGN CURRENCY TRANSACTIONS

     Investment security valuations, other assets, and liabilities initially
     expressed in foreign currencies are converted into U.S. dollars based upon
     current currency exchange rates. Purchases and sales of foreign investment
     securities and income and expenses are converted into U.S. dollars based
     upon currency exchange rates prevailing on the respective dates of such
     transactions.

     Section 988 of the Internal Revenue Code provides that gains or losses on
     certain transactions attributable to fluctuations in foreign currency
     exchange rates must be treated as ordinary income or loss. For financial
     statement purposes, such amounts are included in net realized gains or
     losses.

     E. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expense and the relative size of the funds.

     F. INVESTMENT RISK

     There are certain additional risks involved in investing in foreign
     securities that are not inherent in investments in domestic securities.
     These risks may involve adverse political and economic developments,
     including the possible imposition of capital controls or other foreign
     governmental laws or restrictions. In addition, the securities of some
     foreign companies and securities markets are less liquid and at times may
     be more volatile than securities of comparable U.S. companies and U.S.
     securities markets. The risks described above apply to an even greater
     extent to investments in emerging markets. The securities markets of
     emerging countries are generally smaller, less developed, less liquid, and
     more volatile than the securities markets of the U.S. and developed foreign
     markets.

     G. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Portfolio may enter into contracts
     and agreements that contain a variety of representations and warranties,
     which provide general indemnifications. The maximum exposure to the
     Portfolio under these arrangements is unknown, as this would involve future
     claims that may be made against the Portfolio that have not yet occurred.
     However, based on experience, the Portfolio expects the risks of loss to be
     remote.

     H. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by Standish Mellon Asset Management Company LLC ("Standish Mellon")
     or its affiliates.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services, and general office facilities, is
     paid monthly at the annual rate of 0.40% of the Portfolio's average daily
     net assets.

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio was charged $51,950 during the period ended
     June 30, 2004 and was owed $14,221 as of June 30, 2004.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(5)  FINANCIAL INSTRUMENTS:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved. The
     nature, risks and objectives of these instruments are set forth more fully
     in the Portfolio Trust's registration statement.

     The Portfolio may trade the following financial instruments with
     off-balance sheet risk:

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Portfolio may use options to seek to hedge against
     risks of market exposure and changes in security prices and foreign
     currencies, as well as to seek to enhance returns. Writing puts and buying
     calls tend to increase the Portfolio's exposure to the underlying
     instrument. Buying puts and writing calls tend to decrease the Portfolio's
     exposure to the underlying instrument, or hedge other Portfolio
     investments. Options, both held and written by the Portfolio, are reflected
     in the accompanying Statement of Assets and Liabilities at market value.
     The underlying face amount at value of any open purchased options is shown
     in the Schedule of Investments. This amount reflects each contract's
     exposure to the underlying instrument at period end. Losses may arise from
     changes in the value of the underlying instruments if there is an illiquid
     secondary market for the contract or if the counterparty does not perform
     under the contract's terms.

     Premiums received from writing options which expire are treated as realized
     gains. Premiums received from writing options which are exercised or are
     closed are added to or offset against the proceeds or amount paid on the
     transaction to determine the realized gain or loss. Realized gains and
     losses on purchased options are included in realized gains and losses on
     investment securities, except purchased options on foreign currency which
     are included in realized gains and losses on foreign currency transactions.
     If a put option written by the Portfolio is exercised, the premium reduces
     the cost basis of the securities purchased by the Portfolio. The Portfolio,
     as a writer of an option, has no control over whether the underlying
     securities may be sold (call) or purchased (put) and as a result bears the
     market risk of an unfavorable change in the price of the security
     underlying the written option.

     Exchange traded options are valued at the last sale price, or if no sales
     are reported, the last bid price for purchased options and the last ask
     price for written options. Options traded over-the-counter are valued using
     prices supplied by the dealers.

     FORWARD CURRENCY EXCHANGE CONTRACTS

     The Portfolio may enter into forward foreign currency and cross currency
     exchange contracts for the purchase or sale of a specific foreign currency
     at a fixed price on a future date. Risks may arise upon entering these
     contracts from the potential inability of counterparties to meet the terms
     of their contracts and from unanticipated movements in the value of a
     foreign currency relative to the U.S. dollar and other foreign currencies.
     The forward foreign currency and cross currency exchange contracts are
     marked to market using the forward foreign currency rate of the underlying
     currency and any gains or losses are recorded for financial statement
     purposes as unrealized until the contract settlement date or upon the
     closing of the contract. Forward currency exchange contracts are used by
     the Portfolio primarily to protect the value of the Portfolio's foreign
     securities from adverse currency movements. Unrealized appreciation and
     depreciation of forward currency exchange contracts is included in the
     Statement of Assets and Liabilities.

     At June 30, 2004, the Portfolio held the following forward foreign currency
     exchange contracts:

     FUTURES CONTRACTS

     The Portfolio may enter into financial futures contracts for the delayed
     sale or delivery of securities or contracts based on financial indices at a
     fixed price on a future date. Pursuant to margin requirements the Portfolio
     deposits either cash or securities in an amount equal to a certain
     percentage of the contract amount. Subsequent payments are made or received
     by the Portfolio each day, depending on the daily fluctuations in the value
     of the underlying security, and are recorded for financial statement
     purposes as unrealized gains or losses by the Portfolio. There are several
     risks in connection with the use of futures contracts as a hedging device.
     The change in value of futures contracts primarily corresponds with the
     value of their underlying instruments or indices, which may not correlate
     with changes in the value of hedged investments. Buying futures tends to
     increase the Portfolio's exposure to the underlying instrument, while
     selling futures tends to decrease the Portfolio's exposure to the
     underlying instrument or hedge other investments. In addition, there is the
     risk that the Portfolio may not be able to enter into a closing transaction
     because of an illiquid secondary market. Losses may arise if there is an
     illiquid secondary market or if the counterparty does not perform under the
     contract's terms. The Portfolio enters into financial futures transactions
     primarily to seek to manage its exposure to certain markets and to changes
     in securities prices and foreign currencies. Gains and losses are realized
     upon the expiration or closing of the futures contracts. Futures contracts
     are valued at the quoted daily settlement prices established by the
     exchange on which they trade.

     At June 30, 2004, the Portfolio held no financial futures contracts.

     SWAP AGREEMENTS

     The Portfolio may enter into swap agreements. A swap is an agreement to
     exchange the return generated by one instrument for the return generated by
     another instrument. The Portfolio may enter into interest rate and credit
     default swap agreements to manage its exposure to interest rates and credit
     risk. Interest rate swap agreements involve the exchange by the Portfolio
     with another party of their respective commitments to pay or receive
     interest, e.g., an exchange of floating rate payments for fixed rate
     payments with respect to a notional amount of principal. In a credit
     default swap, one party makes a stream of payments to another party in
     exchange for the right to receive a specified return in the event of a
     default by a third party on its obligation. The Portfolio may use credit
     default swaps to provide a measure of protection against defaults of
     issuers (i.e., to reduce risk where the Portfolio owns or has exposure to
     the corporate


                                       23

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

     or sovereign issuer) or to take an active long or short position with
     respect to the likelihood of a particular corporate or sovereign issuer's
     default. In connection with these agreements, cash or securities may be set
     aside as collateral in accordance with the terms of the swap agreement. The
     Portfolio earns interest on cash set aside as collateral. Swaps are marked
     to market daily based upon quotations from market makers and change in
     value, if any, is recorded as unrealized gain or loss in the Statement of
     Operations. These financial instruments are not actively traded on
     financial markets. The values assigned to these instruments are based upon
     the best available information and because of the uncertainty of the
     valuation, these values may differ significantly from the values that would
     have been realized had a ready market for these instruments existed, and
     differences could be material. Payments received or made from credit
     default swaps at the end of the measurement period are recorded as realized
     gain or loss in the Statement of Operations. Net payments of interest on
     interest rate swap agreements, if any, are included as part of realized
     gain or loss. Entering into these agreements involves, to varying degrees,
     elements of credit, market, and documentation risk in excess of the amounts
     recognized on the Statement of Assets and Liabilities. Such risks involve
     the possibility that there will be no liquid market for these agreements,
     that the counterparty to the agreements may default on its obligation to
     perform or disagree as to the meaning of contractual terms in the
     agreements, and that there may be unfavorable changes in interest rates.

     At June 30, 2004, the Portfolio held no open swap contracts.

(6)  SECURITY LENDING:

     The Portfolio may lend its securities to financial institutions which the
     Portfolio deems to be creditworthy. The loans are collateralized at all
     times with cash or securities with a market value at least equal to the
     market value of the securities on loan. The market value of securities
     loaned is determined daily and any additional required collateral is
     allocated to the Portfolio on the next business day. For the duration of a
     loan, the Portfolio receives the equivalent of the interest or dividends
     paid by the issuer on the securities loaned and also receives compensation
     from the investment of the collateral. As with other extensions of credit,
     the Portfolio bears the risk of delay in recovery or even loss of rights in
     its securities on loan should the borrower of the securities fail
     financially or default on its obligations to the Portfolio. In the event of
     borrower default, the Portfolio generally has the right to use the
     collateral to offset losses incurred. The Portfolio may incur a loss in the
     event it was delayed or prevented from exercising its rights to dispose of
     the collateral. The Portfolio also bears the risk in the event that the
     interest and/or dividends received on invested collateral is not sufficient
     to meet the Portfolio's obligations due on the loans.

     The Portfolio loaned securities during the period ended June 30, 2004
     resulting in $5,182 of security lending income. At June 30, 2004, the
     Portfolio had $12,382,704 worth of securities on loan.

     See the Schedule of Investments for securities out on loan.

(7)  DELAYED DELIVERY TRANSACTIONS:

     The Portfolio may purchase or sell securities on a when-issued, delayed
     delivery or forward commitment basis. Payment and delivery may take place a
     month or more after the date of the transactions. 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. Income on
     the securities will not be earned until settlement date. The Portfolio
     instructs its custodian to segregate securities having value at least equal
     to the amount of the purchase commitment.

     The Portfolio may enter into to be announced ("TBA") purchase commitments
     to purchase securities for a fixed unit price at a future date beyond
     customary settlement time. Although the unit price has been established,
     the principal value has not been finalized. However, the amount of the
     commitments will not fluctuate more than 0.01% from the principal amount.
     The Portfolio holds, and maintains until settlement date, cash or
     high-grade debt obligations in an amount sufficient to meet the purchase
     price, or the Portfolio may enter into offsetting contracts for the forward
     sale of other securities it owns. Income on the securities will not be
     earned until settlement date. TBA purchase commitments may be considered
     securities in themselves, and involve a risk of loss if the value of the
     security to be purchased declines prior to the settlement date, which risk
     is in addition to the risk of decline in the value of the Portfolio's other
     assets. Unsettled TBA purchase commitments are valued at the current market
     value of the underlying securities, according to the procedures described
     under "Investment security valuations" above.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     The Portfolio may enter into TBA sale commitments to hedge its portfolio
     positions. Proceeds of TBA sale commitments are not received until the
     contractual settlement date. During the time a TBA sale commitment is
     outstanding, an offsetting TBA purchase commitment deliverable is held as
     "cover" for the transaction.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     "marked-to-market" daily and the change in market value is recorded by the
     Portfolio as an unrealized gain or loss. If the TBA sale commitment is
     closed through the acquisition of an offsetting purchase commitment, the
     Portfolio realizes a gain or loss. If the Portfolio delivers securities
     under the commitment, the Portfolio realizes a gain or a loss from the sale
     of the securities based upon the unit price established at the date the
     commitment was entered into.

     See the Schedule of Investments for outstanding delayed delivery
     transactions.

8)   LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
     Trust are parties to a committed line of credit facility, which enables
     each portfolio/fund to borrow, in the aggregate, up to $35 million.
     Interest is charged to each participating portfolio/fund based on its
     borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
     1%. In addition, a commitment fee, computed at an annual rate of 0.060 of
     1% on the daily unused portion of the facility, is allocated ratably among
     the participating portfolios/funds at the end of each quarter.

     For the period ended June 30, 2004, the expense related to the commitment
     fee was $428 for the Portfolio.

     During the period ended June 30, 2004, the Portfolio had not borrowed under
     the credit facility.

(a)        The Fund has adopted the provisions of the revised AICPA Audit and
           Accounting Guide for Investment Companies effective January 1, 2001
           and began amortizing premium and discount on all debt securities on
           an effective yield basis. The effect of this change for the year
           ended December 31, 2001 was to decrease net investment income per
           share by $0.05, increase net realized and unrealized gains and losses
           per share by $0.05 and decrease the ratio of net investment income to
           average net assets from 9.20% to 8.86%. Per share data and
           ratios/supplemental data for the periods prior to January 1, 2001

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                       STANDISH MELLON HIGH YIELD BOND FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Investment Trust (the Trust) is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon High Yield Bond Fund (the Fund) is a separate diversified
     investment series of the Trust.

     The objective of the Fund is to maximize total return, consisting primarily
     of a high level of income. The Fund seeks to achieve its objective by
     investing all of its investable assets in an interest of the Standish
     Mellon High Yield Bond Portfolio (the Portfolio), a subtrust of the Mellon
     Institutional Funds Master Portfolio ( the Portfolio Trust), which is
     organized as a New York trust and which has the same investment objective
     as the Fund. The Portfolio seeks to achieve its objective by investing,
     under normal circumstances, at least 80% of net assets in fixed income
     securities issued by U.S. and foreign governments, companies and banks, as
     well as tax-exempt securities, preferred stocks and warrants. The value of
     the Fund's investment in the Portfolio reflects the Fund's proportionate
     interest in the net assets of the Portfolio (approximately 100% at June 30,
     2004). The performance of the Fund is directly affected by the performance
     of the Portfolio. The financial statements of the Portfolio are included
     elsewhere in this report and should be read in conjunction with the Fund's
     financial statements.

     The following is a summary of significant accounting policies followed by
     the Fund in the preparation of its financial statements. The preparation of
     financial statements in accordance with accounting principles generally
     accepted in the United States of America requires management to make
     estimates and assumptions that affect the reported amounts and disclosures
     in the financial statements. Actual results could differ from those
     estimates.

     A. INVESTMENT SECURITY VALUATIONS

     The Fund records its investment in the Portfolio at value. The method by
     which the Portfolio values its securities is discussed in Note 1A of the
     Portfolio's Notes to Financial Statements, which are included elsewhere in
     this report.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Currently, the
     Fund's net investment income consists of the Fund's pro rata share of the
     net investment income of the Portfolio, less all actual and accrued
     expenses of the Fund determined in accordance with accounting principles
     generally accepted in the United States of America. All realized and
     unrealized gains and losses of the Portfolio are allocated pro rata among
     the investors in the Portfolio.

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's dividends from short-term and long-term capital gains, if any, after
     reduction of capital losses will be declared and distributed at least
     annually, as will dividends from net investment income. In determining the
     amounts of its dividends, the Fund will take into account its share of the
     income, gains or losses, expenses, and any other tax items of the
     Portfolio. Dividends from net investment income and distributions from
     capital gains, if any, are reinvested in additional shares of the Fund
     unless a shareholder elects to receive them in cash. Income and capital
     gain distributions are determined in accordance with income tax regulations
     which may differ from accounting principles generally accepted in the
     United States of America. These differences, which may result in
     distribution reclassifications, are primarily due to differing treatments
     for foreign currency transactions, amortization and/or accretion of
     premiums and discounts on certain securities, non-taxable dividends,
     capital loss carryforwards, post-October losses, losses deferred due to
     wash sales and excise tax regulations.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications to undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments and foreign currency transactions may include
     temporary book and tax basis differences which will reverse in a subsequent
     period. Any taxable income or gain remaining at fiscal year end is
     distributed in the following year.

     D. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expense and the relative size of the funds.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     E. COMMITMENT AND CONTINGENCIES

     In the normal course of business, the Fund may enter into contracts and
     agreements that contain a variety of representations and warranties which
     provide general indemnifications. The maximum exposure to the Fund under
     these arrangements is unknown, as this would involve future claims that may
     be made against the Fund that have not yet occurred. However, based on
     experience, the Fund expects the risks of loss to be remote.

     F. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by Standish Mellon Asset Management Company LLC (Standish Mellon),
     or its affiliates.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon, a wholly-owned subsidiary of Mellon Financial Corporation,
     for such services. See Note 2 of the Portfolio's Notes to Financial
     Statements which are included elsewhere in this report. Standish Mellon
     voluntarily agreed to limit the total operating expenses of the Fund and
     it's pro rata share of the Portfolio expenses (excluding commissions, taxes
     and extraordinary expenses) to 0.50% of the Fund's average daily net
     assets. This agreement is voluntary and temporary and may be discontinued
     or revised by Standish Mellon at any time. Pursuant to this agreement, for
     the period ended June 30, 2004, Standish Mellon voluntarily reimbursed the
     Fund for $32,291 of its operating expenses.

     On February 23, 2004, the Fund entered into an agreement with Dreyfus
     Transfer, Inc., a wholly-owned subsidiary of Dreyfus which is an affiliate
     of Standish Mellon, to perform transfer agency services for the Fund.
     Pursuant to this agreement the Fund was charged $1,775 during the period
     ended June 30, 2004 and $1,609 was owed at June 30, 2004.

     The Portfolio compensates Mellon Bank, N.A. under a administration and
     accounting services agreement for providing fund administration and fund
     accounting services for the Portfolio.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, disclosed in the Fund's prospectus, which
     are redeemed or exchanged less than 90 days from the day of their purchase.
     The redemption fee is paid directly to the Fund, and is designed to offset
     brokerage commissions, market impact, and other costs associated with
     short-term trading. The fee does not apply to shares that were acquired
     through reinvestment of distributions. For the period ended June 30, 2004,
     the Fund did receive any redemption fees.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended June 30, 2004 aggregated $6,780,854 and $6,914,377,
     respectively.

(4)  SHARES OF BENEFICIAL INTEREST:

     At June 30, 2004, two shareholders of record held approximately 60% and 13%
     of the total outstanding shares of the Fund. Investment activity of this
     shareholder could have a material impact on the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Master Portfolio (the Portfolio Trust) was
     organized as a master trust fund under the laws of the State of New York on
     January 18, 1996 and is registered under the Investment Company Act of
     1940, as amended, as an open-end, management investment company. Standish
     Mellon High Yield Bond Portfolio (the Portfolio) is a separate diversified
     investment series of the Portfolio Trust.

     The objective of the Portfolio is to maximize total return, consisting
     primarily of a high level of income. The Portfolio seeks to achieve its
     objective by investing, under normal circumstances, at least 80% of net
     assets in fixed income securities issued by U.S. and foreign governments,
     companies and banks, as well as tax-exempt securities, preferred stocks and
     warrants.

     At June 30, 2004 there was one fund, Standish Mellon High Yield Bond Fund
     (the Fund), invested in the Portfolio. The value of the Fund's investment
     in the Portfolio reflects the Fund's proportionate interest in the net
     assets of the Portfolio. The Fund's proportionate interest at June 30, 2004
     was approximately 100%.

     The following is a summary of significant accounting policies followed by
     the Portfolio in the preparation of its financial statements. The
     preparation of financial statements in accordance with accounting
     principles generally accepted in the United States of America requires
     management to make estimates and assumptions that affect the reported
     amounts and disclosures in the financial statements. Actual results could
     differ from those estimates.

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are normally traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     when acquired by the Portfolio are valued at amortized cost, which
     approximates market value. If the Portfolio acquires a short-term
     instrument with more than sixty days remaining to its maturity, it is
     valued at current market value until the sixtieth day prior to maturity and
     will then be valued at amortized value based upon the value on such date
     unless the Trustees determine during such sixty-day period that amortized
     value does not represent fair value.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Interest income
     is determined on the basis of interest accrued, adjusted for discount or
     amortization of premium using the yield--to--maturity method on long-term
     debt securities. Dividend income is recorded on the ex-dividend date.
     Realized gains and losses from securities sold are recorded on the
     identified cost basis. The Portfolio does not isolate that portion of the
     results of operations resulting from changes in foreign exchange rates on
     investments from the fluctuations arising from changes in market prices of
     securities held. Such fluctuations are included with the net realized and
     unrealized gain or loss from investments. Net realized gains and losses on
     foreign currency transactions represent gains and losses on disposition of
     foreign currencies and forward foreign currency exchange contracts,
     currency gains and 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 the Fund's
     books and the U.S. dollar equivalent amounts usually received or paid.

     C. INCOME TAXES

     The Portfolio is treated as a partnership for federal tax purposes. No
     provision is made by the Portfolio for federal or state taxes on any
     taxable income of the Portfolio because each investor in the Portfolio is
     ultimately responsible for the payment of any taxes. Since at least one of
     the Portfolio's investors is a regulated investment company that invests
     all or substantially all of its assets in the Portfolio, the Portfolio
     normally must satisfy the source of income and diversification requirements
     applicable to regulated investment companies (under the Internal Revenue
     Code) in order for its investors to satisfy them. The Portfolio allocates
     at least annually among its investors each investor's distributive share of
     the Portfolio's net investment income, net realized capital gains, and any
     other items of income, gain, loss deduction or credit.

     D. FOREIGN CURRENCY TRANSACTIONS

     Investment security valuations, other assets, and liabilities initially
     expressed in foreign currencies are converted into U.S. dollars based upon
     current currency exchange rates. Purchases and sales of foreign investment
     securities and income and expenses are converted into U.S. dollars based
     upon currency exchange rates prevailing on the respective dates of such
     transactions.

     Section 988 of the Internal Revenue Code provides that gains or losses on
     certain transactions attributable to fluctuations in foreign currency
     exchange rates must be treated as ordinary income or loss. For financial
     statement purposes, such amounts are included in net realized gains or
     losses.

     E. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expense and the relative size of the funds.

     F. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Portfolio may enter into contracts
     and agreements that contain a variety of representations and warranties,
     which provide general indemnifications. The maximum exposure to the
     Portfolio under these arrangements is unknown, as this would involve future
     claims that may be made against the Portfolio that have not yet occurred.
     However, based on experience, the Portfolio expects the risks of loss to be
     remote.

     G. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by Standish Mellon Asset Management Company LLC (Standish Mellon)
     or its affiliates.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services is paid monthly at the annual rate of
     0.50% of the Portfolio's average daily net assets. Standish Mellon
     voluntarily agreed to limit the Portfolio's total annual operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     0.50% of the Portfolio's average daily net assets for the period ended June
     30, 2004. Pursuant to this agreement, for the period ended June 30, 2004,
     Standish Mellon voluntarily did not impose $58,966 of its investment
     advisory fees. This agreement is voluntary and temporary and may be
     discontinued or revised by Standish Mellon at any time.

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio was charged $32,918 during the period ended
     June 30, 2004 and was owed $10,420 at June 30, 2004.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the period ended June 30, 2004 were $16,206,032 and
     $16,553,548, respectively. For the period ended June 30, 2004, the
     Portfolio did not purchase or sell any long-term U.S. government
     securities.

(4)  FEDERAL TAXES:

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at June 30, 2004, as computed on a federal
     income tax basis, were as follows:

                                                  ============

(5)  FINANCIAL INSTRUMENTS:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved. The
     nature, risks and objectives of these instruments are set forth more fully
     in the Portfolio Trust's registration statement.

     The Portfolio may trade the following financial instruments with
     off-balance sheet risk:

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Portfolio may use options to seek to hedge against
     risks of market exposure and changes in security prices and foreign
     currencies, as well as to seek to enhance returns. Writing puts and buying
     calls tend to increase the Portfolio's exposure to the underlying
     instrument. Buying puts and writing calls tend to decrease the Portfolio's
     exposure to the underlying instrument, or hedge other Portfolio
     investments. Options, both held and written by the Portfolio, are reflected
     in the accompanying Statement of Assets and Liabilities at market value.
     The underlying face amount at value of any open purchased options is shown
     in the Schedule of Investments. This amount reflects each contract's
     exposure to the underlying instrument at period end. Losses may arise from
     changes in the value of the underlying instruments if there is an illiquid
     secondary market for the contract or if the counterparty does not perform
     under the contract's terms.

     Premiums received from writing options which expire are treated as realized
     gains. Premiums received from writing options which are exercised or are
     closed are added to or offset against the proceeds or amount paid on the
     transaction to determine the realized gain or loss. Realized gains and
     losses on purchased options are included in realized gains and losses on
     investment securities, except purchased options on foreign currency which
     are included in realized gains and losses on foreign currency transactions.
     If a put option written by the Portfolio is exercised, the premium reduces
     the cost basis of the securities purchased by the Portfolio. The Portfolio,
     as a writer of an option, has no control over whether the underlying
     securities may be sold (call) or purchased (put) and as a result bears the
     market risk of an unfavorable change in the price of the security
     underlying the written option.

     Exchange traded options are valued at the last sale price, or if no sales
     are reported, the last bid price for purchased options and the last ask
     price for written options. Options traded over-the-counter are valued using
     prices supplied by the dealers.

     The Fund had no option activity for the period ended June 30, 2004.

     FORWARD CURRENCY EXCHANGE CONTRACTS

     The Portfolio may enter into forward foreign currency and cross currency
     exchange contracts for the purchase or sale of a specific foreign currency
     at a fixed price on a future date. Risks may arise upon entering these
     contracts from the potential inability of counterparties to meet the terms
     of their contracts and from unanticipated movements in the value of a
     foreign currency relative to the U.S. dollar and other foreign currencies.
     The forward foreign currency and cross currency exchange contracts are
     marked to market using the forward foreign currency rate of the underlying
     currency and any gains or losses are recorded for financial statement
     purposes as unrealized until the contract settlement date or upon the
     closing of the contract. Forward currency exchange contracts are used by
     the Portfolio primarily to protect the value of the Portfolio's foreign
     securities from adverse currency movements. Unrealized appreciation and
     depreciation of forward currency exchange contracts is included in the
     Statement of Assets and Liabilities.

     At June 30, 2004, the Portfolio held the following forward foreign currency
     exchange contracts:

     SWAP AGREEMENTS

     The Portfolio may invest in swap agreements. A swap is an agreement to
     exchange the return generated by one instrument for the return generated by
     another instrument. The Portfolio may enter into interest rate and credit
     default swap agreements to manage its exposure to interest rates and credit
     risk. Interest rate swap agreements involve the exchange by the Portfolio
     with another party of their respective commitments to pay or receive
     interest, e.g., an exchange of floating rate payments for fixed rate
     payments with respect to a notional amount of principal. In a credit
     default swap, one party makes a stream of payments to another party in
     exchange for the right to receive a specified return in the event of a
     default by a third party on its obligation. The Portfolio may use credit
     default swaps to provide a measure of protection against defaults of
     issuers (i.e., to reduce risk where the Portfolio owns or has exposure to
     the corporate or sovereign issuer) or to take an active long or short
     position with respect to the likelihood of a particular corporate or
     sovereign issuer's default. In connection with these agreements, cash or
     securities may be set aside as collateral in accordance with the terms of
     the swap agreement. The Portfolio earns interest on cash set aside as
     collateral. Swaps are marked to market daily based upon quotations from
     market makers and change in value, if any, is recorded as unrealized gain
     or loss in the Statement of Operations. These financial instruments are not
     actively traded on financial markets. The values assigned to these
     instruments are based upon the best available information and because of
     the uncertainty of the valuation, these values may differ significantly
     from the values that would have been realized had a ready market for these
     instruments existed, and differences could be material. Payments received
     or made from credit default swaps at the end of the measurement period are
     recorded as realized gain or loss in the Statement of Operations. Net
     payments of interest on interest rate swap agreements, if any, are included
     as part of realized gain/loss. Entering into these agreements involves, to
     varying degrees, elements of credit, market, and documentation risk in
     excess of the amounts recognized on the Statement of Assets and
     Liabilities. Such risks involve the possibility that there will be no
     liquid market for these agreements, that the counterparty to the agreements
     may default on its obligation to perform or disagree as to the meaning of
     contractual terms in the agreements, and that there may be unfavorable
     changes in interest rates.

     At June 30, 2004 the Portfolio held no open swap contracts:

(6)  SECURITY LENDING:

     The Portfolio may lend its securities to financial institutions which the
     Portfolio deems to be creditworthy. The loans are collateralized at all
     times with cash or securities with a market value at least equal to the
     market value of the securities on loan. The market value of securities
     loaned is determined daily and any additional required collateral is
     allocated to the Portfolio on the next business day. For the duration of a
     loan, the Portfolio receives the equivalent of the interest or dividends
     paid by the issuer on the securities loaned and also receives compensation
     from the investment of the collateral. As with other extensions of credit,
     the Portfolio bears the risk of delay in recovery or even loss of rights in
     its securities on loan should the borrower of the securities fail
     financially or default on its obligations to the Portfolio. In the event of
     borrower default, the Portfolio generally has the right to use the
     collateral to offset losses incurred. The Portfolio may incur a loss in the
     event it was delayed or prevented from exercising its rights to dispose of
     the collateral. The Portfolio also bears the risk in the event that the
     interest and/or dividends received on invested collateral is not sufficient
     to meet the Portfolio's obligations due on the loans.

     The Portfolio loaned securities during the period ended June 30, 2004
     resulting in $8,737 of security lending income. At June 30, 2004 the
     Portfolio had $10,025,880 worth of securities on loan.

     See the Schedule of Investments for the securities that are on loan.

(7)  DELAYED DELIVERY TRANSACTIONS:

     The Portfolio may purchase or sell securities on a when-issued, delayed
     delivery or forward commitment basis. Payment and delivery may take place a
     month or more after the date of the transactions. 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. Income on
     the securities will not be earned until settlement date. The Portfolio
     instructs its custodian to segregate securities having value at least equal
     to the amount of the purchase commitment.

     The Portfolio may enter into to be announced (TBA) purchase commitments to
     purchase securities for a fixed unit price at a future date beyond
     customary settlement time. Although the unit price has been established,
     the principal value has not been finalized. However, the amount of the
     commitments will not fluctuate more than 0.01% from the principal amount.
     The Portfolio holds, and maintains until settlement date, cash or
     high-grade debt obligations in an amount sufficient to meet the purchase
     price, or the Portfolio may enter into offsetting contracts for the forward
     sale of other securities it owns. Income on the securities will not be
     earned until settlement date. TBA purchase commitments may be considered
     securities in themselves, and involve a risk of loss if the value of the
     security to be purchased declines prior to the settlement date, which risk
     is in addition to the risk of decline in the value of the Portfolio's other
     assets. Unsettled TBA purchase commitments are valued at the current market
     value of the underlying securities, according to the procedures described
     under Investment security valuations above.

     The Portfolio may enter into TBA sale commitments to hedge its portfolio
     positions. Proceeds of TBA sale commitments are not received until the
     contractual settlement date. During the time a TBA sale commitment is
     outstanding, an offsetting TBA purchase commitment deliverable is held as
     cover for the transaction.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under Investment security valuations above. The contract is
     marked-to-market daily and the change in market value is recorded by the
     Portfolio as an unrealized gain or loss. If the TBA sale commitment is
     closed through the acquisition of an offsetting purchase commitment, the
     Portfolio realizes a gain or loss. If the Portfolio delivers securities
     under the commitment, the Portfolio realizes a gain or a loss from the sale
     of the securities based upon the unit price established at the date the
     commitment was entered into.

     At June 30, 2004, the Portfolio held no delayed delivery transactions.

(8)  CONCENTRATION OF RISK:

     The Portfolio invests in low rated (non-investment grade) and comparable
     quality unrated high yield securities. Investments in high yield securities
     are accompanied by a greater degree of credit risk and the value of high
     yield securities tends to be more sensitive to economic conditions than
     higher rated securities. The risk of loss due to default of an issuer may
     be significantly greater for holders of high yield securities, because such
     securities are generally unsecured and are often subordinated to other
     creditors of the issuer.

     There are certain additional considerations and risks associated with
     investing in foreign securities and currency transactions that are not
     inherent with investments of domestic origin. The Portfolio's investment in
     emerging market countries may involve greater risks than investments in
     more developed markets and the price of such investments may be volatile.
     These risks of investing in foreign and emerging markets may include
     foreign currency exchange rate fluctuations, perceived credit risk, adverse
     political and economic developments and possible adverse foreign government
     intervention.

(9)  LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
     Trust are parties to a committed line of credit facility, which enables
     each portfolio/fund to borrow, in the aggregate, up to $35 million.
     Interest is charged to each participating portfolio/fund based on its
     borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
     1%. In addition, a commitment fee, computed at an annual rate of .060 of 1%
     on the daily unused portion of the facility, is allocated ratably among the
     participating portfolios/funds at the end of each quarter.

     For the period ended June 30, 2004, the expense related to the commitment
     fee was $1,153 for the Portfolio.

     During the period ended June 30, 2004, the Portfolio had borrowed under the
     credit facility resulting in $7 of interest expense.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                STANDISH MELLON INTERNATIONAL FIXED INCOME FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon International Fixed Income Fund (the "Fund") is a separate
     non-diversified investment series of the Trust.

     During the period ended June 30, 2004 the Fund had offered two classes of
     shares: Institutional Class and Service Class. On April 30, 2004 the
     Service Class was liquidated and closed. Expenses of the Fund, until the
     time when the Service Class was closed, were borne pro-rata by the holders
     of each class of shares, except for transfer agent fees and an account
     service fee of up to 0.25% of the average daily net assets of the Service
     Class of shares. Each class voted separately as a class only with respect
     to its own service plan (Service Class only) or other matters that relate
     only to that class. Shares of the Service Class received their pro-rata
     share of the net assets of the Fund (after satisfaction of any
     class-specific expenses) when the Service Class was liquidated.

     The objective of the Fund is to maximize total return while realizing a
     market level of income consistent with preserving principal and liquidity.
     The Fund seeks to achieve its objective by investing, under normal
     circumstances, at least 80% of net assets in fixed income securities. The
     Fund also invests, under normal circumstances, at least 65% of net assets
     in non-U.S. dollar denominated fixed income securities of foreign
     governments and companies located in various countries, including emerging
     markets.

     The following is a summary of significant accounting policies followed by
     the Fund in the preparation of its financial statements. The preparation of
     financial statements in accordance with accounting principles generally
     accepted in the United States of America requires management to make
     estimates and assumptions that affect the reported amounts and disclosures
     in the financial statements. Actual results could differ from those
     estimates.

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     when acquired by the Fund are valued at amortized cost, which approximates
     market value. If the Fund acquires a short-term instrument with more than
     sixty days remaining to its maturity, it is valued at current market value
     until the sixtieth day prior to maturity and will then be valued at
     amortized value based upon the value on such date unless the Trustees
     determine during such sixty-day period that amortized value does not
     represent fair value.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method on
     long-term debt securities. Realized gains and losses from securities sold
     are recorded on the identified cost basis. The Fund does not isolate that
     portion of the results of operations resulting from changes in foreign
     exchange rates on investments from the fluctuations arising from changes in
     market prices of securities held. Such fluctuations are included with the
     net realized and unrealized gain or loss from investments. Net realized
     gains and losses on foreign currency transactions represent gains and
     losses on disposition of foreign currencies and forward foreign currency
     exchange contracts, currency gains and 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
     the Fund's books and the U.S. dollar equivalent amounts usually received or
     paid.

     C. FOREIGN CURRENCY TRANSACTIONS

     Investment security valuations, other assets, and liabilities initially
     expressed in foreign currencies are converted into U.S. dollars based upon
     current currency exchange rates. Purchases and sales of foreign investment
     securities and income and expenses are converted into U.S. dollars based
     upon currency exchange rates prevailing on the respective dates of such
     transactions.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                STANDISH MELLON INTERNATIONAL FIXED INCOME FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     Section 988 of the Internal Revenue Code provides that gains or losses on
     certain transactions attributable to fluctuations in foreign currency
     exchange rates must be treated as ordinary income or loss. For financial
     statement purposes, such amounts are included in net realized gains or
     losses.

     D. INVESTMENT RISK

     There are certain additional risks involved in investing in foreign
     securities that are not inherent in investments in domestic securities.
     These risks may involve adverse political and economic developments,
     including the possible imposition of capital controls or other foreign
     governmental laws or restrictions. In addition, the securities of some
     foreign companies and securities markets are less liquid and at times may
     be more volatile than securities of comparable U.S. companies and U.S.
     securities markets. The risks described above apply to an even greater
     extent to investments in emerging markets. The securities markets of
     emerging countries are generally smaller, less developed, less liquid, and
     more volatile than the securities markets of the U.S. and developed foreign
     markets.

     E. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income and distributions from capital gains,
     if any, are reinvested in additional shares of the Fund unless the
     shareholder elects to receive them in cash. Income and capital gain
     distributions are determined in accordance with income tax regulations
     which may differ from accounting principles generally accepted in the
     United States of America. These differences, which may result in
     distribution reclassifications, are primarily due to differing treatments
     for foreign currency transactions, futures, amortization and/or accretion
     of premiums and discounts on certain securities, capital loss
     carryforwards, losses deferred due to wash sales and excise tax
     regulations.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications among undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments and foreign currency transactions may include
     temporary book and tax basis differences which will reverse in a subsequent
     period. Any taxable income or gain remaining at fiscal year end is
     distributed in the following year.

     F. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expense and the relative size of the funds.

     G. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Fund may enter into contracts and
     agreements that contain a variety of representations and warranties, which
     provide general indemnifications. The maximum exposure to the Fund under
     these arrangements is unknown, as this would involve future claims that may
     be made against the Fund that have not yet occurred. However, based on
     experience, the Fund expects the risks of loss to be remote.

     H. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by Standish Mellon Asset Management Company LLC ("Standish Mellon")
     or its affiliates.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to Standish Mellon, a wholly-owned
     subsidiary of Mellon Financial Corporation, for overall investment advisory
     and administrative services, and general office facilities is paid monthly
     at the annual rate of 0.40% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit the Service Class operating
     expenses (excluding brokerage commissions, taxes and extraordinary
     expenses) for the period ended June 30, 2004, so that the Service Class
     annual operating expenses did not exceed the total operating expenses of
     the Institutional Class (net of any expense limitation) for the comparable
     period plus 0.25% (the maximum Service Fee). Pursuant to this agreement,
     for the period ended June 30, 2004, Standish Mellon reimbursed the Service
     Class $2,032 for class specific operating expenses.

                STANDISH MELLON INTERNATIONAL FIXED INCOME FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     On February 23, 2004, the Fund entered into an agreement with Dreyfus
     Transfer, Inc., a wholly owned subsidiary of Dreyfus which is an affiliate
     of Standish Mellon to provide transfer agent services to the Fund. Pursuant
     to this agreement the Fund was charged $3,500 during the period ended June
     30, 2004 and $3,500 was owed at June 30, 2004.

     The Fund compensates Mellon Bank, N.A., under a custody, administration and
     accounting services agreement for providing custody, fund administration
     and fund accounting services for the fund. Pursuant to this agreement the
     Fund was charged $106,142 during the period ended June 30, 2004 and $
     33,151 was owed at June 30, 2004.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     90 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that are acquired through reinvestment of
     distributions. For the period ended June 30, 2004, the Fund received $504
     of redemption fees.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     investments, for the period ended June 30, 2004 were as follows:

        At June 30, 2004, three shareholders held of record approximately 8%, 6%
        and 6% of the total outstanding shares of the Fund.

        A significant portion of the Fund's shares are beneficially owned by
        fiduciary accounts over which Standish Mellon and its affiliates have
        either sole or joint investment discretion. Investment activity of these
        shareholders could have a material impact on the Fund.

(6)  FINANCIAL INSTRUMENTS:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved. The
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     The Fund may trade the following instruments with off-balance sheet risk:

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Fund may use options to seek to hedge against risks of
     market exposure and changes in securities prices and foreign currencies, as
     well as to seek to enhance returns. Writing puts and buying calls tend to
     increase the Fund's exposure to the underlying instrument. Buying puts and
     writing calls tend to decrease the Fund's exposure to the underlying
     instrument, or hedge other Fund investments. Options, both held and written
     by the Fund, are reflected in the accompanying Statement of Assets and
     Liabilities at market value. The underlying face amount at value of any
     open purchased options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     end. Losses may arise from changes in the value of the underlying
     instruments, if there is an illiquid secondary market for the contract or
     if the counterparty does not perform under the contract's terms.

     Premiums received from writing options which expire are treated as realized
     gains. Premiums received from writing options which are exercised or are
     closed are added to or offset against the proceeds or amount paid on the
     transaction to determine the realized gain or loss. Realized gains and
     losses on purchased options are included in realized gains and losses on
     investment securities, except purchased options on foreign currency which
     are included in realized gains and losses on foreign currency transactions.
     If a put option written by the Fund is exercised, the premium reduces the
     cost basis of the securities purchased by the Fund. The Fund, as writer of
     an option, has no control over whether the underlying securities may be
     sold (call) or purchased (put) and as a result bears the market risk of an
     unfavorable change in the price of the security underlying the written
     option.

     Exchange traded options are valued at the last sale price, or if no sales
     are reported, the last bid price for purchased options and the last ask
     price for written options. Options traded over-the-counter are valued using
     prices supplied by the dealers.

     A summary of the written put options for the period ended June 30, 2004 is
     as follows:

     FORWARD CURRENCY EXCHANGE CONTRACTS

     The Fund may enter into forward foreign currency and cross currency
     exchange contracts for the purchase or sale of a specific foreign currency
     at a fixed price on a future date. Risks may arise upon entering these
     contracts from the potential inability of counterparties to meet the terms
     of their contracts and from unanticipated movements in the value of a
     foreign currency relative to the U.S. dollar and other foreign currencies.
     The forward foreign currency and cross currency exchange contracts are
     marked to market using the forward foreign currency rate of the underlying
     currency and any gains or losses are recorded for financial statement
     purposes as unrealized until the contract settlement date or upon the
     closing of the contract. Forward currency exchange contracts are used by
     the Fund primarily to protect the value of the Fund's foreign securities
     from adverse currency movements. Unrealized appreciation and depreciation
     of forward currency exchange contracts is included in the Statement of
     Assets and Liabilities.

    FUTURES CONTRACTS

    The Fund may enter into financial futures contracts for the delayed sale or
    delivery of securities or contracts based on financial indices at a fixed
    price on a future date. Pursuant to the margin requirements, the Fund
    deposits either cash or securities in an amount equal to a certain
    percentage of the contract amount. Subsequent payments are made or received
    by the Fund each day, depending on the daily fluctuations in the value of
    the underlying security, and are recorded for financial statement purposes
    as unrealized gains or losses by the Fund. There are several risks in
    connection with the use of futures contracts as a hedging device. The change
    in value of futures contracts primarily corresponds with the value of their
    underlying instruments or indices, which may not correlate with changes in
    the value of hedged investments. Buying futures tends to increase the Fund's
    exposure to the underlying instrument, while selling futures tends to
    decrease the Fund's exposure to the underlying instrument or hedge other
    Fund investments. In addition, there is the risk that the Fund may not be
    able to enter into a closing transaction because of an illiquid secondary
    market. Losses may arise if there is an illiquid secondary market or if the
    counterparties do not perform under the contract's terms. The Fund enters
    into financial futures transactions primarily to manage its exposure to
    certain markets and to changes in securities prices and foreign currencies.
    Gains and losses are realized upon the expiration or closing of the futures
    contracts. Futures contracts are valued at the quoted daily settlement
    prices established by the exchange on which they trade.

     SWAP AGREEMENTS

     The Fund may enter into swap agreements. A swap is an agreement to exchange
     the return generated by one instrument for the return generated by another
     instrument. The Fund may enter into interest rate and credit default swap
     agreements to manage its exposure to interest rates and credit risk.
     Interest rate swap agreements involve the exchange by the Fund with another
     party of their respective commitments to pay or receive interest, e.g., an
     exchange of floating rate payments for fixed rate payments with respect to
     a notional amount of principal. In a credit default swap, one party makes a
     stream of payments to another party in exchange for the right to receive a
     specified return in the event of a default by a third party on its
     obligation. The Fund may use credit default swaps to provide a measure of
     protection against defaults of issuers (i.e., to reduce risk where the Fund
     owns or has exposure to the corporate or sovereign issuer) or to take an
     active long or short position with respect to the likelihood of a
     particular corporate or sovereign issuer's default. In connection with
     these agreements, cash or securities may be set aside as collateral in
     accordance with the terms of the swap agreement. The Fund earns interest on
     cash set aside as collateral. Swaps are marked to market daily based upon
     quotations from market makers and change in value, if any, is recorded as
     unrealized gain or loss in the Statement of Operations. These financial
     instruments are not actively traded on financial markets. The values
     assigned to these instruments are based upon the best available information
     and because of the uncertainty of the valuation, these values may differ
     significantly from the values that would have been realized had a ready
     market for these instruments existed, and differences could be material.
     Payments received or made from credit default swaps at the end of the
     measurement period are recorded as realized gain or loss in the Statement
     of Operations. Net payments of interest on interest rate swap agreements,
     if any, are included as part of realized gain or loss. Entering into these
     agreements involves, to varying degrees, elements of credit, market, and
     documentation risk in excess of the amounts recognized on the Statement of
     Assets and Liabilities. Such risks involve the possibility that there will
     be no liquid market for these agreements, that the counterparty to the
     agreements may default on its obligation to perform or disagree as to the
     meaning of contractual terms in the agreements, and that there may be
     unfavorable changes in interest rates.

     At June 30, 2004, the Fund held no open swap contracts:

(7)  SECURITY LENDING:

     The Fund may lend its securities to financial institutions which the Fund
     deems to be creditworthy. The loans are collateralized at all times with
     cash or securities with a market value at least equal to the market value
     of the securities on loan. The market value of securities loaned is
     determined daily and any additional required collateral is allocated to the
     Fund on the next business day. For the duration of a loan, the Fund
     receives the equivalent of the interest or dividends paid by the issuer on
     the securities loaned and also receives compensation from the investment of
     the collateral. As with other extensions of credit, the Fund bears the risk
     of delay in recovery or even loss of rights in its securities on loan
     should the borrower of the securities fail financially or default on its
     obligations to the Fund. In the event of borrower default, the Fund
     generally has the right to use the collateral to offset losses incurred.
     The Fund may incur a loss in the event it was delayed or prevented from
     exercising its rights to dispose of the collateral. The Fund also bears the
     risk in the event that the interest and/or dividends received on invested
     collateral is not sufficient to meet the Fund's obligations due on the
     loans.

     The Fund loaned securities during the period ended June 30, 2004 resulting
     in $9,913 of security lending income. At June 30, 2004 the Fund had
     $1,952,464 worth of securities on loan.

     See the Statement of Investments for further detail on the security
     positions on loan.

(8)  LINE OF CREDIT:

     The Fund, and other subtrusts in the Portfolio Trust and funds in the Trust
     are parties to a committed line of credit facility, which enables each
     portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is
     charged to each participating portfolio/fund based on its borrowings at a
     rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition,
     a commitment fee, computed at an annual rate of 0.060 of 1% on the daily
     unused portion of the facility, is allocated ratably among the
     participating portfolios/funds at the end of each quarter.

     For the period ended June 30, 2004, the expense related to the commitment
     fee was $1,500 for the Fund.

     During the period ended June 30, 2004, the Fund had not borrowed under the
     credit facility.

(a) The Fund has adopted the provisions of the revised AICPA Audit and
    Accounting Guide for Investment Companies effective January 1, 2001 and
    began amortizing premium and discount on all debt securities on an effective
    yield basis. The effect of this change for the year ended December 31, 2001
    was to decrease net investment income per share by $0.002, increase net
    realized and unrealized gains and losses per share by $0.002 and decrease
    the ratio of net investment income to average net assets from 4.00% to
    3.99%. Per share data and ratios/supplemental data for the periods prior to
    January 1, 2001 have not been restated to reflect this change in
    presentation.

(1) Calculated based on average shares outstanding.

+   Computed on an annualized basis using a 366 day calendar year.

++  Not annualized.

+++ Total return would have been lower in the absence of fee waivers and expense
    limitations.

    securities of foreign government and companies located in various countries,
    including emerging markets.

    The following is a summary of significant accounting policies followed by
    the Fund in the preparation of its financial statements. The preparation of
    financial statements in accordance with accounting principles generally
    accepted in the United States of America requires management to make
    estimates and assumptions that affect the reported amounts and disclosures
    in the financial statements. Actual results could differ from those
    estimates.

    A. INVESTMENT SECURITY VALUATIONS

    Securities for which quotations are readily available are valued at the last
    sale price, or if no sale price, at the closing bid price in the principal
    market in which such securities are primarily traded. Market quotations are
    not considered to be readily available for certain debt obligations; such
    investments are stated at fair value on the basis of valuations furnished by
    a pricing service or dealers, approved by the Trustees, which determine
    valuations for normal institutional-size trading units of such securities
    using methods based on market transactions for comparable securities and
    variable relationships between securities that are generally recognized by
    institutional traders. Securities (including illiquid securities) for which
    quotations are not readily available are valued at their fair value as
    determined in good faith under consistently applied procedures under the
    general supervision of the Trustees.

    Short-term instruments with less than sixty-one days remaining to maturity
    when acquired by the Fund are valued at amortized cost, which approximates
    market value. If the Fund acquires a short-term instrument with more than
    sixty days remaining to its maturity, it is valued at current market value
    until the sixtieth day prior to maturity and will then be valued at
    amortized value based upon the value on such date unless the Trustees
    determine during such sixty-day period that amortized value does not
    represent fair value.

    B. SECURITIES TRANSACTIONS AND INCOME

    Securities transactions are recorded as of trade date. Interest income is
    determined on the basis of interest accrued, adjusted for accretion of
    discount or amortization of premium using the yield-to-maturity method on
    long-term debt securities. Realized gains and losses from securities sold
    are recorded on the identified cost basis. The Fund does not isolate that
    portion of the results of operations resulting from changes in foreign
    exchange rates on investments from the fluctuations arising from changes in
    market prices of securities held. Such fluctuations are included with the
    net realized and unrealized gain or loss from investments. Net realized
    gains and losses on foreign currency transactions represent gains and losses
    on disposition of foreign currencies and forward foreign currency exchange
    contracts, currency gains and 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 the
    Fund's books and the U.S. dollar equivalent amounts usually received or
    paid.

    C. FOREIGN CURRENCY TRANSACTIONS

    Investment security valuations, other assets, and liabilities initially
    expressed in foreign currencies are converted into U.S. dollars based upon
    current currency exchange rates. Purchases and sales of foreign investment
    securities and income and expenses are converted into U.S. dollars based
    upon currency exchange rates prevailing on the respective dates of such
    transactions.

    Section 988 of the Internal Revenue Code provides that gains or losses on
    certain transactions attributable to fluctuations in foreign currency
    exchange rates must be treated as ordinary income or loss. For financial
    statement purposes, such amounts are included in net realized gains or
    losses.

    D. INVESTMENT RISK

    There are certain additional risks involved in investing in foreign
    securities that are not inherent in investments in domestic securities.
    These risks may involve adverse political and economic developments,
    including the possible imposition of capital controls or other foreign
    governmental laws or restrictions. In addition, the securities of some
    foreign companies and securities markets are less liquid and at times may be
    more volatile than securities of comparable U.S. companies and U.S.
    securities markets. The risks described above apply to an even greater
    extent to investments in emerging markets. The securities markets of
    emerging countries are generally smaller, less developed, less liquid, and
    more volatile than the securities markets of the U.S. and developed foreign
    markets.

    E. DISTRIBUTIONS TO SHAREHOLDERS

    Distributions to shareholders are recorded on the ex-dividend date.
    Dividends from net investment income and distributions from capital gains,
    if any, are reinvested in additional shares of the Fund unless the
    shareholder elects to receive them in cash. Income and capital gain
    distributions are determined in accordance with income tax regulations which
    may differ from accounting principles generally accepted in the United
    States of America. These differences, which may result in distribution
    reclassifications, are primarily due to differing treatments for foreign
    currency transactions, futures, amortization and/or accretion of premiums
    and discounts on certain securities, capital loss carryforwards, losses
    deferred due to wash sales and excise tax regulations.

    Permanent book and tax basis differences relating to shareholder
    distributions will result in reclassifications among undistributed net
    investment income, accumulated net realized gain (loss) and paid in capital.
    Undistributed net investment income and accumulated net realized gain (loss)
    on investments and foreign currency transactions may include temporary book
    and tax basis differences which will reverse in a subsequent period. Any
    taxable income or gain remaining at fiscal year end is distributed in the
    following year.

    F. EXPENSES

    The majority of expenses of the Trust are directly identifiable to an
    individual fund. Expenses which are not readily identifiable to a specific
    fund are allocated taking into consideration, among other things, the nature
    and type of expense and the relative size of the funds.

    H. COMMITMENTS AND CONTINGENCIES

    In the normal course of business, the Fund may enter into contracts and
    agreements that contain a variety of representations and warranties, which
    provide general indemnifications. The maximum exposure to the Fund under
    these arrangements is unknown, as this would involve future claims that may
    be made against the Fund that have not yet occurred. However, based on
    experience, the Fund expects the risks of loss to be remote.

    G. AFFILIATED ISSUERS

    Issuers in which the fund held investments in other investment companies
    advised by Standish Mellon Asset Management Company LLC ("Standish Mellon")
    or its affiliates.

(2) INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

    The investment advisory fee paid to Standish Mellon, a wholly-owned
    subsidiary of Mellon Financial Corporation, for overall investment advisory
    and administrative services, and general office facilities is paid monthly
    at the annual rate of 0.40% of the Fund's average daily net assets. Standish
    Mellon voluntarily agreed to limit the Fund's total annual operating
    expenses (excluding brokerage commissions, taxes and extraordinary expenses)
    to 0.75% of the Fund's average daily net assets for the period ended June
    30, 2004. Pursuant to this agreement, for the period ended June 30, 2004,
    Standish Mellon voluntarily did not impose $37,582 of its investment
    advisory fee. This agreement is voluntary and temporary and may be
    discontinued or revised by Standish Mellon at any time.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

    On February 23, 2004, the The Fund entered into an agreement with Dreyfus
    Transfer, Inc., a wholly owned subsidiary of Dreyfus, which is an affiliate
    of Standish Mellon, to perform transfer agency services for the Fund.
    Pursuant to this agreement the Fund was charged $2,983 during the period
    ended June 30, 2004 and $2,492 was owed at June 30, 2004.

    The Fund compensates Mellon Bank, N.A., under a custody, administration and
    accounting services agreement for providing custody, fund administration and
    fund accounting services for the fund. Pursuant to this agreement the Fund
    was charged $39,579 during the period ended June 30, 2004 and owed $12,271
    at June 30, 2004.

    The Fund imposes a redemption fee of 2% of the net asset value of the
    shares, with certain exceptions, which are redeemed or exchanged less than
    90 days from the day of their purchase. The redemption fee is paid directly
    to the Fund, and is designed to offset brokerage commissions, market impact,
    and other costs associated with short-term trading in the Fund. The fee does
    not apply to shares that are acquired through reinvestment of distributions.
    For the period ended June 30, 2004, the Fund received no redemption fees.

    No director, officer or employee of Standish Mellon or its affiliates
    receives any compensation from the Trust or the Fund for serving as an
    officer or Trustee of the Trust. The Trust pays each Trustee who is not a
    director, officer or employee of Standish Mellon or its affiliates an annual
    fee and a per meeting fee as well as reimbursement for travel and out of
    pocket expenses. In addition, the Trust pays the legal fees for the
    independent counsel of the Trustees.

(3) PURCHASES AND SALES OF INVESTMENTS:

    Purchases and proceeds from sales of investments, other than short-term
    investments, for the period ended June 30, 2004 were as follows:

(4) SHARES OF BENEFICIAL INTEREST:

    The Declaration of Trust permits the Trustees to issue an unlimited number
    of full and fractional shares of beneficial interest having a par value of
    one cent per share. Transactions in Fund shares were as follows:

                                                     ============       ===========


    At June 30, 2004, two shareholders held of record approximately 73% and 10%
    of the total outstanding shares of the Fund.

    A significant portion of the Fund's shares are beneficially owned by
    fiduciary accounts over which Standish Mellon and its affiliates have either
    sole or joint investment discretion. Investment activity of these
    shareholders could have a material impact on the Fund.

(5) FEDERAL TAXES:

    As a regulated investment company qualified under Subchapter M of the
    Internal Revenue Code, the Fund is not subject to income taxes to the extent
    that it distributes substantially all of its taxable income for its fiscal
    year.

(6) FINANCIAL INSTRUMENTS:

    In general, the following instruments are used for hedging purposes as
    described below. However, these instruments may also be used to seek to
    enhance potential gain in circumstances where hedging is not involved. The
    nature, risks and objectives of these instruments are set forth more fully
    in the Fund's Prospectus and Statement of Additional Information.

    The Fund may trade the following instruments with off-balance sheet risk:

    OPTIONS

    Call and put options give the holder the right to purchase or sell a
    security or currency or enter into a swap arrangement on a future date at a
    specified price. The Fund may use options to seek to hedge against risks of
    market exposure and changes in securities prices and foreign currencies, as
    well as to seek to enhance returns. Writing puts and buying calls tend to
    increase the Fund's exposure to the underlying instrument. Buying puts and
    writing calls tend to decrease the Fund's exposure to the underlying
    instrument, or hedge other Fund investments. Options, both held and written
    by the Fund, are reflected in the accompanying Statement of Assets and
    Liabilities at market value. The underlying face amount at value of any open
    purchased options is shown in the Schedule of Investments. This amount
    reflects each contract's exposure to the underlying instrument at period
    end. Losses may arise from changes in the value of the underlying
    instruments, if there is an illiquid secondary market for the contract or if
    the counterparty does not perform under the contract's terms.

    Premiums received from writing options which expire are treated as realized
    gains. Premiums received from writing options which are exercised or are
    closed are added to or offset against the proceeds or amount paid on the
    transaction to determine the realized gain or loss. Realized gains and
    losses on purchased options are included in realized gains and losses on
    investment securities, except purchased options on foreign currency which
    are included in realized gains and losses on foreign currency transactions.
    If a put option written by the Fund is exercised, the premium reduces the
    cost basis of the securities purchased by the Fund. The Fund, as writer of
    an option, has no control over whether the underlying securities may be sold
    (call) or purchased (put) and as a result bears the market risk of an
    unfavorable change in the price of the security underlying the written
    option.

    Exchange traded options are valued at the last sale price, or if no sales
    are reported, the last bid price for purchased options and the last ask
    price for written options. Options traded over-the-counter are valued using
    prices supplied by the dealers.

     At June 30, 2004, the Fund held the following option contracts:

    FORWARD CURRENCY EXCHANGE CONTRACTS

    The Fund may enter into forward foreign currency and cross currency exchange
    contracts for the purchase or sale of a specific foreign currency at a fixed
    price on a future date. Risks may arise upon entering these contracts from
    the potential inability of counterparties to meet the terms of their
    contracts and from unanticipated movements in the value of a foreign
    currency relative to the U.S. dollar and other foreign currencies. The
    forward foreign currency and cross currency exchange contracts are marked to
    market using the forward foreign currency rate of the underlying currency
    and any gains or losses are recorded for financial statement purposes as
    unrealized until the contract settlement date or upon the closing of the
    contract. Forward currency exchange contracts are used by the Fund primarily
    to protect the value of the Fund's foreign securities from adverse currency
    movements. Unrealized appreciation and depreciation of forward currency
    exchange contracts is included in the Statement of Assets and Liabilities.

    FUTURES CONTRACTS

    The Fund may enter into financial futures contracts for the delayed sale or
    delivery of securities or contracts based on financial indices at a fixed
    price on a future date. Pursuant to the margin requirements, the Fund
    deposits either cash or securities in an amount equal to a certain
    percentage of the contract amount. Subsequent payments are made or received
    by the Fund each day, depending on the daily fluctuations in the value of
    the underlying security, and are recorded for financial statement purposes
    as unrealized gains or losses by the

    Fund. There are several risks in connection with the use of futures
    contracts as a hedging device. The change in value of futures contracts
    primarily corresponds with the value of their underlying instruments or
    indices, which may not correlate with changes in the value of hedged
    investments. Buying futures tends to increase the Fund's exposure to the
    underlying instrument, while selling futures tends to decrease the Fund's
    exposure to the underlying instrument or hedge other Fund investments. In
    addition, there is the risk that the Fund may not be able to enter into a
    closing transaction because of an illiquid secondary market. Losses may
    arise if there is an illiquid secondary market or if the counterparties do
    not perform under the contract's terms. The Fund enters into financial
    futures transactions primarily to manage its exposure to certain markets and
    to changes in securities prices and foreign currencies. Gains and losses are
    realized upon the expiration or closing of the futures contracts. Futures
    contracts are valued at the quoted daily settlement prices established by
    the exchange on which they trade.

    At June 30, 2004 the Fund held the following futures contracts:

    SWAP AGREEMENTS

    The Fund may enter into swap agreements. A swap is an agreement to exchange
    the return generated by one instrument for the return generated by another
    instrument. The Fund may enter into interest rate and credit default swap
    agreements to manage its exposure to interest rates and credit risk.
    Interest rate swap agreements involve the exchange by the Fund with another
    party of their respective commitments to pay or receive interest, e.g., an
    exchange of floating rate payments for fixed rate payments with respect to a
    notional amount of principal. In a credit default swap, one party makes a
    stream of payments to another party in exchange for the right to receive a
    specified return in the event of a default by a third party on its
    obligation. The Fund may use credit default swaps to provide a measure of
    protection against defaults of issuers (i.e., to reduce risk where the Fund
    owns or has exposure to the corporate or sovereign issuer) or to take an
    active long or short position with respect to the likelihood of a particular
    corporate or sovereign issuer's default. In connection with these
    agreements, cash or securities may be set aside as collateral in accordance
    with the terms of the swap agreement. The Fund earns interest on cash set
    aside as collateral. Swaps are marked to market daily based upon quotations
    from market makers and change in value, if any, is recorded as unrealized
    gain or loss in the Statement of Operations. These financial instruments are
    not actively traded on financial markets. The values assigned to these
    instruments are based upon the best available information and because of the
    uncertainty of the valuation, these values may differ significantly from the
    values that would have been realized had a ready market for these
    instruments existed, and differences could be material. Payments received or
    made from credit default swaps at the end of the measurement period are
    recorded as realized gain or loss in the Statement of Operations. Net
    payments of interest on interest rate swap agreements, if any, are included
    as part of realized gain or loss. Entering into these agreements involves,
    to varying degrees, elements of credit, market, and documentation risk in
    excess of the amounts recognized on the Statement of Assets and Liabilities.
    Such risks involve the possibility that there will be no liquid market for
    these agreements, that the counterparty to the agreements may default on its
    obligation to perform or disagree as to the meaning of contractual terms in
    the agreements, and that there may be unfavorable changes in interest rates.

    At June 30, 2004, the Fund held no open swap contracts.

(7) SECURITY LENDING:

    The Fund may lend its securities to financial institutions which the Fund
    deems to be creditworthy. The loans are collateralized at all times with
    cash or securities with a market value at least equal to the market value of
    the securities on loan. The market value of securities loaned is determined
    daily and any additional required collateral is allocated to the Fund on the
    next business day. For the duration of a loan, the Fund receives the
    equivalent of the interest or dividends paid by the issuer on the securities
    loaned and also receives compensation from the investment of the collateral.
    As with other extensions of credit, the Fund bears the risk of delay in
    recovery or even loss of rights in its securities on loan should the
    borrower of the securities fail financially or default on its obligations to
    the Fund. In

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

    the event of borrower default, the Fund generally has the right to use the
    collateral to offset losses incurred. The Fund may incur a loss in the event
    it was delayed or prevented from exercising its rights to dispose of the
    collateral. The Fund also bears the risk in the event that the interest
    and/or dividends received on invested collateral is not sufficient to meet
    the Fund's obligations due on the loans.

    The Fund loaned securities during the period ended June 30, 2004 resulting
    in $2,050 of security lending income. At June 30, 2004 the Fund had $512,646
    worth of securities on loan.

    See the Schedule of Investments for the securities that are on loan.

(8) DELAYED DELIVERY TRANSACTIONS:

    The Fund may purchase or sell securities on a when-issued, delayed delivery
    or forward commitment basis. This Fund segregates securities having a value
    at least equal to the amount of the purchase commitment.

    The Fund may enter into to be announced ("TBA") purchase commitments to
    purchase securities for a fixed unit price at a future date beyond customary
    settlement time. Although the unit price has been established, the principal
    value has not been finalized. However, the amount of the commitments will
    not fluctuate more than 0.01% from the principal amount. The Fund holds, and
    maintains until settlement date, cash or high-grade debt obligations in an
    amount sufficient to meet the purchase price, or the Fund may enter into
    offsetting contracts for the forward sale of other securities it owns.
    Income on the securities will not be earned until settlement date. TBA
    purchase commitments may be considered securities in themselves, and involve
    a risk of loss if the value of the security to be purchased declines prior
    to the settlement date, which risk is in addition to the risk of the decline
    in the value of the Fund's other assets. Unsettled TBA purchase commitments
    are valued at the current market value of the underlying securities,
    according to the procedures described under "Investment security valuations"
    above.

    The Fund may enter into TBA sale commitments to hedge its portfolio
    positions. Proceeds of TBA sale commitments are not received until the
    contractual settlement date. During the time a TBA sale commitment is
    outstanding, an offsetting TBA purchase commitment deliverable is held as
    "cover" for the transaction.

    Unsettled TBA sale commitments are valued at the current market value of the
    underlying securities, generally according to the procedures described under
    "Investment security valuations" above. The contract is 'marked-to-market'
    daily and the change in market value is recorded by the Fund as an
    unrealized gain or loss. If the TBA sale commitment is closed through the
    acquisition of an offsetting purchase commitment, the Fund realizes a gain
    or loss from the sale of the securities based upon the unit price
    established at the date the commitment was entered into.

    At June 30, 2004, the Fund did not have any delayed delivery transactions.

(9) LINE OF CREDIT:

    The Fund, and other subtrusts in the Portfolio Trust and funds in the Trust
    are parties to a committed line of credit facility, which enables each
    portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is
    charged to each participating portfolio/fund based on its borrowings at a
    rate equal to the Federal Funds effective rate plus 1_2 of 1%. In addition,
    a commitment fee, computed at an annual rate of 0.060 of 1% on the daily
    unused portion of the facility, is allocated ratably among the participating
    portfolios/funds at the end of each quarter.

    For the period ended June 30, 2004, the expense related to the commitment
    fee was $105 for the Fund.

    During the period ended June 30, 2004, the Fund had not borrowed under the
    credit facility.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                   STANDISH MELLON INVESTMENT GRADE BOND FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1) SIGNIFICANT ACCOUNTING POLICIES:

    Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
    Massachusetts business trust and is registered under the Investment Company
    Act of 1940, as amended, as an open-end, management investment company.
    Standish Mellon Investment Grade Bond Fund (the "Fund") is a separate
    diversified investment series of the Trust.

    The objective of the Fund is to maximize total return, consistent with
    preserving principal and liquidity, primarily through the generation of
    current income and, to a lesser extent, capital appreciation. The Fund seeks
    to achieve its objective by investing, under normal circumstances, at least
    80% of net assets in investment grade fixed income securities including, but
    not limited to, government, agency, corporate and mortgage and asset-backed
    issues.

    The following is a summary of significant accounting policies followed by
    the Fund in the preparation of its financial statements. The preparation of
    financial statements in accordance with accounting principles generally
    accepted in the United States of America requires management to make
    estimates and assumptions that affect the reported amounts and disclosures
    in the financial statements. Actual results could differ from those
    estimates.

    A. INVESTMENT SECURITY VALUATIONS

    Securities for which quotations are readily available are valued at the last
    sale price, or if no sale price, at the closing bid price in the principal
    market in which such securities are primarily traded. Market quotations are
    not considered to be readily available for certain debt obligations; such
    investments are stated at fair value on the basis of valuations furnished by
    a pricing service or dealers, approved by the Trustees, which determine
    valuations for normal institutional-size trading units of such securities
    using methods based on market transactions for comparable securities and
    variable relationships between securities that are generally recognized by
    institutional traders. Securities (including illiquid securities) for which
    quotations are not readily available are valued at their fair value as
    determined in good faith under consistently applied procedures under the
    general supervision of the Trustees.

    Short-term instruments with less than sixty-one days remaining to maturity
    when acquired by the Fund are valued at amortized cost, which approximates
    market value. If the Fund acquires a short-term instrument with more than
    sixty days remaining to its maturity, it is valued at current market value
    until the sixtieth day prior to maturity and will then be valued at
    amortized value based upon the value on such date unless the Trustees
    determine during such sixty-day period that amortized value does not
    represent fair value.

    B. SECURITIES TRANSACTIONS AND INCOME

    Securities transactions are recorded as of the trade date. Interest income
    is determined on the basis of interest accrued, adjusted for accretion of
    discount or amortization of premium using the yield-to-maturity method on
    long-term debt securities. Dividend income is recorded on the ex-dividend
    date. Realized gains and losses from securities sold are recorded on the
    identified cost basis.

    C. DISTRIBUTIONS TO SHAREHOLDERS

    Distributions to shareholders are recorded on the ex-dividend date.
    Dividends from net investment income and distributions from capital gains,
    if any, are reinvested in additional shares of the Fund unless the
    shareholder elects to receive them in cash. Income and capital gain
    distributions are determined in accordance with income tax regulations which
    may differ from generally accepted accounting principles. These differences,
    which may result in distribution reclassifications, are primarily due to
    differing treatments for losses deferred due to wash sales, amortization
    and/or accretion of premiums and discounts on certain securities and the
    timing of recognition of gains and losses on futures contracts.

    Permanent book and tax basis differences relating to shareholder
    distributions will result in reclassifications among undistributed net
    investment income, accumulated net realized gain (loss) and paid in capital.
    Undistributed net investment income and accumulated net realized gain (loss)
    on investments may include temporary book and tax basis differences which
    will reverse in a subsequent period. Any taxable income or gain remaining at
    fiscal year end is distributed in the following year.

    D. EXPENSES

    The majority of expenses of the Trust are directly identifiable to an
    individual fund. Expenses which are not readily identifiable to a specific
    fund are allocated taking into consideration, among other things, the nature
    and type of expense and the relative size of the funds.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

    E. COMMITMENTS AND CONTINGENCIES

    In the normal course of business, the Fund may enter into contracts and
    agreements that contain a variety of representations and warranties, which
    provide general indemnifications. The maximum exposure to the Fund under
    these arrangements is unknown, as this would involve future claims that may
    be made against the Fund that have not yet occurred. However, based on
    experience, the Fund expects the risks of loss to be remote.

    F. AFFILIATED ISSUERS

    Issuers in which the Fund held investments in other investment companies
    advised by to Standish Mellon Asset Management Company LLC ("Standish
    Mellon") or its affiliates.

(2) INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

    The investment advisory fee paid to Standish Mellon, a wholly-owned
    subsidiary of Mellon Financial Corporation, for overall investment advisory
    and administrative services and general office facilities, is paid monthly
    at the annual rate of 0.40% of the Fund's average daily net assets. Standish
    Mellon voluntarily agreed to limit total Fund operating expenses (excluding
    brokerage commissions, taxes and extraordinary expenses) to 0.40% of the
    Fund's average daily net assets for the period ended June 30, 2004. Pursuant
    to this agreement, for the period ended June 30, 2004, Standish Mellon
    voluntarily did not impose $91,471 of its investment advisory fee. This
    agreement is voluntary and temporary and may be discontinued or revised by
    Standish Mellon at any time.

    As of February 23, 2004, the The Fund compensates Dreyfus Transfer, Inc., a
    wholly owned subsidiary of Dreyfus, which is an affiliate of Standish
    Mellon, under a transfer agency agreement for providing personnel and
    facilities to perform transfer agency services for the Fund. Pursuant to
    this agreement the Fund was charged $2,428 during the period ended June 30,
    2004 and $2,428 was owed at June 30, 2004.

    The Fund compensates Mellon Bank, N.A., under a custody, administration and
    accounting services agreement for providing custody, fund administration and
    fund accounting services for the fund. Pursuant to this agreement the Fund
    was charged $41,459 during the period ended June 30, 2004 and $10,461 was
    owed at June 30, 2004.

    No director, officer or employee of Standish Mellon or its affiliates
    receives any compensation from the Trust or the Fund for serving as an
    officer or Trustee of the Trust. The Trust pays each Trustee who is not a
    director, officer or employee of Standish Mellon or its affiliates an annual
    fee and a per meeting fee as well as reimbursement for travel and out of
    pocket expenses. In addition, the Trust pays the legal fees for the
    independent counsel of the Trustees.

(3) PURCHASES AND SALES OF INVESTMENTS:

    Purchases and proceeds from sales of investments, other than short-term
    obligations, for the period ended June 30, 2004 were as follows:

    At June 30, 2004, three shareholders of record held approximately 67%, 15%
    and 9% of the total outstanding shares of the Fund. Investment activity of
    these shareholders could have a material impact on the Fund.

(5) FEDERAL TAXES:

    As a regulated investment company qualified under Subchapter M of the
    Internal Revenue Code, the Fund is not subject to income taxes to the extent
    that it distributes all of its taxable income for its fiscal year.

    The cost and unrealized appreciation (depreciation) in value of the
    investment securities owned at June 30, 2004, as computed on a federal
    income tax basis, were as follows:

(6) FINANCIAL INSTRUMENTS:

    In general, the following instruments are used for hedging purposes as
    described below. However, these instruments may also be used to seek to
    enhance potential gain in circumstances where hedging is not involved. The
    nature, risks and objectives of these instruments are set forth more fully
    in the Fund's Prospectus and Statement of Additional Information.

    The Fund may trade the following instruments with off-balance sheet risk:

    OPTIONS

    Call and put options give the holder the right to purchase or sell a
    security or currency or enter into a swap arrangement on a future date at a
    specified price. The Fund may use options to seek to hedge against risks of
    market exposure and changes in securities prices and foreign currencies, as
    well as to seek to enhance returns. Writing puts and buying calls tend to
    increase the Fund's exposure to the underlying instrument. Buying puts and
    writing calls tend to decrease the Fund's exposure to the underlying
    instrument, or hedge other Fund investments. Options, both held and written
    by the Fund, are reflected in the accompanying Statement of Assets and
    Liabilities at market value. The underlying face amount at value of any open
    purchased options is shown in the Schedule of Investments. This amount
    reflects each contract's exposure to the underlying instrument at period
    end. Losses may arise from changes in the value of the underlying
    instruments, if there is an illiquid secondary market for the contract or if
    the counterparty does not perform under the contract's terms.

    Premiums received from writing options which expire are treated as realized
    gains. Premiums received from writing options which are exercised or are
    closed are added to or offset against the proceeds or amount paid on the
    transaction to determine the realized gain or loss. Realized gains and
    losses on purchased options are included in realized gains and losses on
    investment securities, except purchased options on foreign currency which
    are included in realized gains and losses on foreign currency transactions.
    If a put option written by the Fund is exercised, the premium reduces the
    cost basis of the securities purchased by the Fund. The Fund, as writer of
    an option, has no control over whether the underlying securities may be sold
    (call) or purchased (put) and as a result bears the market risk of an
    unfavorable change in the price of the security underlying the written
    option.

    Exchange traded options are valued at the last sale price, or if no sales
    are reported, the last bid price for purchased options and the last ask
    price for written options. Options traded over-the-counter are valued using
    prices supplied by the dealers.

    A summary of the written put options for the period ended June 30, 2004 is
    as follows:

    At June 30, 2004, the Fund had segregated sufficient securities for open
    written options:

    INTEREST RATE FLOORS

    Interest rate floors purchased by the Fund entitle the Fund to receive
    payments on a notional principal amount from the party selling such floor to
    the extent that a specified index falls below a predetermined interest rate
    amount. Credit and market risk exist with respect to these instruments. If
    forecasts of interest rates and other market factors are incorrect,
    investment performance will diminish compared to what performance would have
    been if these investment techniques were not used. Even if the forecasts are
    correct, there are risks that the positions may correlate imperfectly with
    the asset or liability being hedged, a liquid secondary market may not
    always exist, or counterparty to a transaction may not perform. The Fund
    expects to enter these transactions primarily for hedging purposes
    including, but not limited to, preserving a return or spread on a particular
    investment or portion of its portfolio, protecting against currency
    fluctuations, as a duration management technique or protecting against an
    increase in the price of securities the Fund anticipates purchasing at a
    later date. Interest rate floors are marked-to-market daily based on
    quotations from market makers and the change, if any, is recorded as
    unrealized appreciation or depreciation in the Statement of Operations.
    Realized gains or losses from these agreements are disclosed in the
    Statement of Operations.

    At June 30, 2004, the Fund held no open interest rate floor agreements.

    FUTURES CONTRACTS

    The Fund may enter into financial futures contracts for the delayed sale or
    delivery of securities or contracts based on financial indices at a fixed
    price on a future date. Pursuant to the margin requirements, the Fund
    deposits either cash or securities in an amount equal to a certain
    percentage of the contract amount. Subsequent payments are made or received
    by the Fund each day, depending on the daily fluctuations in the value of
    the underlying security, and are recorded for financial statement purposes
    as unrealized gains or losses by the Fund. There are several risks in
    connection with the use of futures contracts as a hedging device. The change
    in value of futures contracts primarily corresponds with the value of their
    underlying instruments or indices, which may not correlate with changes in
    the value of hedged investments. Buying futures tends to increase the Fund's
    exposure to the underlying instrument, while selling futures tends to
    decrease the Fund's exposure to the underlying instrument or hedge other
    Fund investments. In addition, there is the risk that the Fund may not be
    able to enter into a closing transaction because of an illiquid secondary
    market. Losses may arise if there is an illiquid secondary market or if the
    counterparties do not perform under the contract's terms. The Fund enters
    into financial futures transactions primarily to manage its exposure to
    certain markets and to changes in securities prices and foreign currencies.
    Gains and losses are realized upon the expiration or closing of the futures
    contracts. Futures contracts are valued at the quoted daily settlement
    prices established by the exchange on which they trade.

    At June 30,2004, the Fund held the following financials futures contracts:



                                                                              UNDERLYING FACE          UNREALIZED

    SWAP AGREEMENTS

    The Fund may enter into swap agreements. A swap is an agreement to exchange
    the return generated by one instrument for the return generated by another
    instrument. The Fund may enter into interest rate and credit default swap
    agreements to manage its exposure to interest rates and credit risk.
    Interest rate swap agreements involve the exchange by the Fund with another
    party of their respective commitments to pay or receive interest, e.g., an
    exchange of floating rate payments for fixed rate payments with respect to a
    notional amount of principal. In a credit default swap, one party makes a
    stream of payments to another party in exchange for the right to receive a
    specified return in the event of a default by a third party on its
    obligation. The Fund may use credit default swaps to provide a measure of
    protection against defaults of issuers (i.e., to reduce risk where the Fund
    owns or has exposure to the corporate or sovereign issuer) or to take an
    active long or short position with respect to the likelihood of a particular
    corporate or sovereign issuer's default. In connection with these
    agreements, cash or securities may be set aside as collateral in accordance
    with the terms of the swap agreement. The Fund earns interest on cash set
    aside as collateral. Swaps are marked to market daily based upon quotations
    from market makers and change in value, if any, is recorded as unrealized
    gain or loss in the Statement of Operations. These financial instruments are
    not actively traded on financial markets. The values assigned to these
    instruments are based upon the best available information and because of the
    uncertainty of the valuation, these values may differ significantly from the
    values that would have been realized had a ready market for these
    instruments existed, and differences could be material. Payments received or
    made from credit default swaps at the end of the measurement period are
    recorded as realized gain or loss in the Statement of Operations. Net
    payments of interest on interest rate swap agreements, if any, are included
    as part of realized gain or loss. Entering into these agreements involves,
    to varying degrees, elements of credit, market, and documentation risk in
    excess of the amounts recognized on the Statement of Assets and Liabilities.
    Such risks involve the possibility that there will be no liquid market for
    these agreements, that the counterparty to the agreements may default on its
    obligation to perform or disagree as to the meaning of contractual terms in
    the agreements, and that there may be unfavorable changes in interest rates.

    At June 30, 2004, the Fund held the following open swap contracts:

(7) SECURITY LENDING:

    The Fund may lend its securities to financial institutions which the Fund
    deems to be creditworthy. The loans are collateralized at all times with
    cash or securities with a market value at least equal to the market value of
    the securities on loan. The market value of securities loaned is determined
    daily and any additional required collateral is allocated to the Fund on the
    next business day. For the duration of a loan, the Fund receives the
    equivalent of the interest or dividends paid by the issuer on the securities
    loaned and also receives compensation from the investment of the collateral.
    As with other extensions of credit, the Fund bears the risk of delay in
    recovery or even loss of rights in its securities on loan should the
    borrower of the securities fail financially or default on its obligations to
    the Fund. In the event of borrower default, the Fund generally has the right
    to use the collateral to offset losses incurred. The Fund may incur a loss
    in the event it was delayed or prevented from exercising its rights to
    dispose of the collateral. The Fund also bears the risk in the event that
    the interest and/or dividends received on invested collateral is not
    sufficient to meet the Fund's obligations due on the loans.

    The Fund loaned securities during the period ended June 30, 2004 resulting
    in $4,672 of security lending income. At June 30, 2004, the Fund had
    $7,794,809 worth of securities on loan.

    See the Schedule of Investments for the securities that are on loan.

(8) DELAYED DELIVERY TRANSACTIONS:

    The Fund may purchase or sell securities on a when-issued, delayed delivery
    or forward commitment basis. This Fund segregates securities having a value
    at least equal to the amount of the purchase commitment.

    The Fund may enter into to be announced ("TBA") purchase commitments to
    purchase securities for a fixed unit price at a future date beyond customary
    settlement time. Although the unit price has been established, the principal
    value has not been finalized. However, the amount of the commitments will
    not fluctuate more than 0.01% from the principal amount. The Fund holds, and
    maintains until settlement date, cash or high-grade debt obligations in an
    amount sufficient to meet the purchase price, or the Fund may enter into
    offsetting contracts for the forward sale of other securities it owns.
    Income on the securities will not be earned until settlement date. TBA
    purchase commitments may be considered securities in themselves, and involve
    a risk of loss if the value of the security to be purchased declines prior
    to the settlement date, which risk is in addition to the risk of the decline
    in the value of the Fund's other assets. Unsettled TBA purchase commitments
    are valued at the current market value of the underlying securities,
    according to the procedures described under "Investment security valuations"
    above.

    The Fund may enter into TBA sale commitments to hedge its portfolio
    positions. Proceeds of TBA sale commitments are not received until the
    contractual settlement date. During the time a TBA sale commitment is
    outstanding, an offsetting TBA purchase commitment deliverable is held as
    "cover" for the transaction.

    Unsettled TBA sale commitments are valued at the current market value of the
    underlying securities, generally according to the procedures described under
    "Investment security valuations" above. The contract is 'marked-to-market'
    daily and the change in market value is recorded by the Fund as an
    unrealized gain or loss. If the TBA sale commitment is closed through the
    acquisition of an offsetting purchase commitment, the Fund realizes a gain
    or loss from the sale of the securities based upon the unit price
    established at the date the commitment was entered into.

    See the Schedule of Investments for outstanding delayed delivery contracts.

(9) LINE OF CREDIT:

    The Fund, and other subtrusts in the Portfolio Trust and funds in the Trust
    are parties to a committed line of credit facility, which enables each
    portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is
    charged to each participating portfolio/fund based on its borrowings at a
    rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition,
    a commitment fee, computed at an annual rate of 0.060 of 1% on the daily
    unused portion of the facility, is allocated ratably among the participating
    portfolios/funds at the end of each quarter.

    For the period ended June 30, 2004, the expense related to the commitment
    fee was $250 for the Fund.

    During the period ended June 30, 2004, the Fund had not borrowed under the
    credit facility.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
            STANDISH MELLON OPPORTUNISTIC EMERGING MARKETS DEBT FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon Opportunistic Emerging Markets Debt Fund (the "Fund") is a
     separate non-diversified investment series of the Trust.

     The objective of the Fund is to generate a high total return through a
     combination of capital appreciation and income. The fund seeks to achieve
     its objective by investing, under normal circumstances, at least 80% of net
     assets in fixed income securities issued by governments, companies and
     banks of emerging markets, as well as preferred stocks, warrants and
     tax-exempt bonds.

     The following is a summary of significant accounting policies followed by
     the Fund in the preparation of its financial statements. The preparation of
     financial statements in accordance with accounting principles generally
     accepted in the United States of America requires management to make
     estimates and assumptions that affect the reported amounts and disclosures
     in the financial statements. Actual results could differ from those
     estimates.

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     when acquired by the Fund are valued at amortized cost, which approximates
     market value. If the Fund acquires a short-term instrument with more than
     sixty days remaining to its maturity, it is valued at current market value
     until the sixtieth day prior to maturity and will then be valued at
     amortized value based upon the value on such date unless the Trustees
     determine during such sixty-day period that amortized value does not
     represent fair value.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Interest income
     is determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method on
     long-term debt securities. Dividend income is recorded on the ex-dividend
     date. Realized gains and losses from securities sold are recorded on the
     identified cost basis. The Fund does not isolate that portion of the
     results of operations resulting from changes in foreign exchange rates on
     investments from the fluctuations arising from changes in market prices of
     securities held. Such fluctuations are included with the net realized and
     unrealized gain or loss from investments. Net realized gains and losses on
     foreign currency transactions represent gains and losses on disposition of
     foreign currencies and forward foreign currency exchange contracts,
     currency gains and 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 the Fund's
     books and the U.S. dollar equivalent amounts usually received or paid.

     C. FOREIGN CURRENCY TRANSACTIONS

     Investment security valuations, other assets, and liabilities initially
     expressed in foreign currencies are converted into U.S. dollars based upon
     current currency exchange rates. Purchases and sales of foreign investment
     securities and income and expenses are converted into U.S. dollars based
     upon currency exchange rates prevailing on the respective dates of such
     transactions.

     Section 988 of the Internal Revenue Code provides that gains or losses on
     certain transactions attributable to fluctuations in foreign currency
     exchange rates must be treated as ordinary income or loss. For financial
     statement purposes, such amounts are included in net realized gains or
     losses.

     D. INVESTMENT RISK

     There are certain additional risks involved in investing in foreign
     securities that are not inherent in investments in domestic securities.
     These risks may involve adverse political and economic developments,
     including the possible imposition of capital controls or other foreign
     governmental laws or restrictions. In addition, the securities of some
     foreign companies and securities markets are less liquid and at times


                                       10


                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
            STANDISH MELLON OPPORTUNISTIC EMERGING MARKETS DEBT FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     may be more volatile than securities of comparable U.S. companies and U.S.
     securities markets. The risks described above apply to an even greater
     extent to investments in emerging markets. The securities markets of
     emerging countries are generally smaller, less developed, less liquid, and
     more volatile than the securities markets of the U.S. and developed foreign
     markets.

     E. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. Dividends from net investment income and
     distributions from capital gains, if any, are reinvested in additional
     shares of the Fund unless the shareholder elects to receive them in cash.
     Income and capital gain distributions are determined in accordance with
     income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in distribution reclassifications, are primarily due to
     differing treatments for losses deferred due to wash sales, foreign
     currency gains and losses, post-October losses, amortization and/or
     accretion of premiums and discounts on certain securities and the timing of
     recognition of gains and losses on futures contracts.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications among undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments and foreign currency transactions may include
     temporary book and tax basis differences which will reverse in a subsequent
     period. Any taxable income or gain remaining at fiscal year end is
     distributed in the following year.

     F. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expense and the relative size of the funds.

     G. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Fund may enter into contracts and
     agreements that contain a variety of representations and warranties, which
     provide general indemnifications. The maximum exposure to the Fund under
     these arrangements is unknown, as this would involve future claims that may
     be made against the Fund that have not yet occurred. However, based on
     experience, the Fund expects the risks of loss to be remote.

     H. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by Standish Mellon Asset Management Company LLC ("Standish Mellon")
     or its affiliates.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to Standish Mellon, a wholly-owned
     subsidiary of Mellon Financial Corporation, for overall investment advisory
     and administrative services, and general office facilities, is paid monthly
     at the annual rate of 0.50% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit total Fund operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     0.30% of the Fund's average daily net assets for the period ended June 30,
     2004. Pursuant to this agreement, for the period ended June 30, 2004,
     Standish Mellon voluntarily did not impose $38,338 of its investment
     advisory fee and reimbursed the Fund for $30,411 of its operating expenses.
     This agreement is voluntary and temporary and may be discontinued or
     revised by Standish Mellon at any time.

      As of February 23, 2004, the The Fund compensates Dreyfus Transfer, Inc.,
     a wholly owned subsidiary of Dreyfus, which is an affiliate of Standish
     Mellon, under a transfer agency agreement for providing personnel and
     facilities to perform transfer agency services for the Fund. Pursuant to
     this agreement the Fund was charged $2,301 during the period ended June 30,
     2004 and $2,301 was owed at June 30, 2004.

     The Fund compensates Mellon Bank, N.A., under a custody, administration and
     accounting services agreement for providing custody, fund administration
     and fund accounting services for the fund. Pursuant to this agreement the
     Fund was charged $22,675 during the period ended June 30, 2004 and $7,131
     was owed at June 30, 2004.

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

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the period ended June 30, 2004 were as follows:

(6)  FINANCIAL INSTRUMENTS:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved. The
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     The Fund may trade the following instruments with off-balance sheet risk:

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Fund may use options to seek to hedge against risks of
     market exposure and changes in securities prices and foreign currencies, as
     well as to seek to enhance returns. Writing puts and buying calls tend to
     increase the Fund's exposure to the underlying instrument. Buying puts and
     writing calls tend to decrease the Fund's exposure to the underlying
     instrument, or hedge other Fund investments. Options, both held and written
     by the Fund, are reflected in the accompanying Statement of Assets and
     Liabilities at market value. The underlying face amount at value of any
     open purchased options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     end. Losses may arise from changes in the value of the underlying
     instruments, if there is an illiquid secondary market for the contract or
     if the counterparty does not perform under the contract's terms.

     Premiums received from writing options which expire are treated as realized
     gains. Premiums received from writing options which are exercised or are
     closed are added to or offset against the proceeds or amount paid on the
     transaction to determine the realized gain or loss. Realized gains and
     losses on purchased options are included in realized gains and losses on
     investment securities, except purchased options on foreign currency which
     are included in realized gains and losses on foreign currency transactions.
     If a put option written by the Fund is exercised, the premium reduces the
     cost basis of the securities purchased by the Fund. The Fund, as writer of
     an option, has no control over whether the underlying securities may be
     sold (call) or purchased (put) and as a result bears the market risk of an
     unfavorable change in the price of the security underlying the written
     option.

     Exchange traded options are valued at the last sale price, or if no sales
     are reported, the last bid price for purchased options and the last ask
     price for written options. Options traded over-the-counter are valued using
     prices supplied by the dealers.

     At June 30, 2004, the Fund held no written or purchased options.

     During the period ended June 30, 2004 the Funds option transactions were as
     follows:

     FORWARD CURRENCY EXCHANGE CONTRACTS

     The Fund may enter into forward foreign currency and cross currency
     exchange contracts for the purchase or sale of a specific foreign currency
     at a fixed price on a future date. Risks may arise upon entering these
     contracts from the potential inability of counterparties to meet the terms
     of their contracts and from unanticipated movements in the value of a
     foreign currency relative to the U.S. dollar and other foreign currencies.
     The forward foreign currency and cross currency exchange contracts are
     marked to market using the forward foreign currency rate of the underlying
     currency and any gains or losses are recorded for financial statement
     purposes as unrealized until the contract settlement date or upon the
     closing of the contract. Forward currency exchange contracts are used by
     the Fund primarily to protect the value of the Fund's foreign securities
     from adverse currency movements. Unrealized appreciation and depreciation
     of forward currency exchange contracts is included in the Statement of
     Assets and Liabilities.

     At June 30, 2004, the Fund held the following forward foreign currency or
     cross currency exchange contracts:

     Euro                                45,000          9/15/2004       54,763           54,394            $(369)


     FUTURES CONTRACTS

     The Fund may enter into financial futures contracts for the delayed sale or
     delivery of securities or contracts based on financial indices at a fixed
     price on a future date. Pursuant to the margin requirements, the Fund
     deposits either cash or securities in an amount equal to a certain
     percentage of the contract amount. Subsequent payments are made or received
     by the Fund each day, depending on the daily fluctuations in the value of
     the underlying security, and are recorded for financial statement purposes
     as unrealized gains or losses by the Fund. There are several risks in
     connection with the use of futures contracts as a hedging device. The
     change in value of futures contracts primarily corresponds with the value
     of their underlying instruments or indices, which may not correlate with
     changes in the value of hedged investments. Buying futures tends to
     increase the Fund's exposure to the underlying instrument, while selling
     futures tends to decrease the Fund's exposure to the underlying instrument
     or hedge other Fund investments. In addition, there is the risk that the
     Fund may not be able to enter into a closing transaction because of an
     illiquid secondary market. Losses may arise if there is an illiquid
     secondary market or if the counterparties do not perform under the
     contract's terms. The Fund enters into financial futures transactions
     primarily to manage its exposure to certain markets and to changes in
     securities prices and foreign currencies. Gains and losses are realized
     upon the expiration or closing of the futures contracts. Futures contracts
     are valued at the quoted daily settlement prices established by the
     exchange on which they trade.

     At June 30, 2004, the Fund held no outstanding financial futures contracts

(7)  SECURITY LENDING:

     The Fund may lend its securities to financial institutions which the Fund
     deems to be creditworthy. The loans are collateralized at all times with
     cash or securities with a market value at least equal to the market value
     of the securities on loan. The market value of securities loaned is
     determined daily and any additional required collateral is allocated to the
     Fund on the next business day. For the duration of a loan, the Fund
     receives the equivalent of the interest or dividends paid by the issuer on
     the securities loaned and also receives compensation from the investment of
     the collateral. As with other extensions of credit, the Fund bears the risk
     of delay in recovery or even loss of rights in its securities on loan
     should the borrower of the securities fail financially or default on its
     obligations to the Fund. In the event of borrower default, the Fund
     generally has the right to use the collateral to offset losses incurred.
     The Fund may incur a loss in the event it was delayed or prevented from
     exercising its rights to dispose of the collateral. The Fund also bears the
     risk in the event that the interest and/or dividends received on invested
     collateral is not sufficient to meet the Fund's obligations due on the
     loans.

     The Fund loaned securities during the period ended June 30, 2004 resulting
     $2,687 of security lending income. At June 30, 2004, the Fund had $519,521
     worth of securities on loan.

     See the Statement of Investments for further detail on the security
     positions on loan.

(8)  DELAYED DELIVERY TRANSACTIONS:

     The Fund may purchase or sell securities on a when-issued, delayed delivery
     or forward commitment basis. This Fund segregates securities having a value
     at least equal to the amount of the purchase commitment.

     The Portfolio may enter into to be announced ("TBA") purchase commitments
     to purchase securities for a fixed unit price at a future date beyond
     customary settlement time. Although the unit price has been established,
     the principal value has not been finalized. However, the amount of the
     commitments will not fluctuate more than 0.01% from the principal amount.
     The Portfolio holds, and maintains until settlement date, cash or
     high-grade debt obligations in an amount sufficient to meet the purchase
     price, or the Portfolio may enter into offsetting contracts for the forward
     sale of other securities it owns. Income on the securities will not be
     earned until settlement date. TBA purchase commitments may be considered
     securities in themselves, and involve a risk of loss if the value of the
     security to be purchased declines prior to the settlement date, which risk
     is in addition to the risk of decline in the value of the Portfolio's other
     assets. Unsettled TBA purchase commitments are valued at the current market
     value of the underlying securities, according to the procedures described
     under "Investment security valuations" above.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
            STANDISH MELLON OPPORTUNISTIC EMERGING MARKETS DEBT FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     The Fund may enter into TBA sale commitments to hedge its portfolio
     positions. Proceeds of TBA sale commitments are not received until the
     contractual settlement date. During the time a TBA sale commitment is
     outstanding, an offsetting TBA purchase commitment deliverable is held as
     "cover" for the transaction.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     "marked-to-market" daily and the change in market value is recorded by the
     Fund as an unrealized gain or loss. If the TBA sale commitment is closed
     through the acquisition of an offsetting purchase commitment, the Portfolio
     realizes a gain or loss. If the Portfolio delivers securities under the
     commitment, the Portfolio realizes a gain or a loss from the sale of the
     securities based upon the unit price established at the date the commitment
     was entered into.

     At June 30, 2004, the Fund held no delayed delivery transactions.

(9)  LINE OF CREDIT:

     The Fund, and other subtrusts in the Portfolio Trust and funds in the Trust
     are parties to a committed line of credit facility, which enables each
     portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is
     charged to each participating portfolio/fund based on its borrowings at a
     rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition,
     a commitment fee, computed at an annual rate of .060 of 1% on the daily
     unused portion of the facility, is allocated ratably among the
     participating portfolios/funds at the end of each quarter.

     For the period ended June 30, 2004, the expense related to the commitment
     fee was $60 for the Fund.

     During the period ended June 30, 2004, the Fund had not borrowed under the
     credit facility.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                  STANDISH MELLON OPPORTUNISTIC HIGH YIELD FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon Opportunistic High Yield Fund (the "Fund") is a separate
     non-diversified investment series of the Trust.

     The objective of the Fund is to maximize total return, consistent with
     preserving principal, primarily through the generation of current income
     and, to a lesser extent, capital appreciation by investing, under normal
     circumstances, at least 80% of net assets in below investment grade fixed
     income securities.

     The following is a summary of significant accounting policies followed by
     the Fund in the preparation of its financial statements. The preparation of
     financial statements in accordance with accounting principles generally
     accepted in the United States of America requires management to make
     estimates and assumptions that affect the reported amounts and disclosures
     in the financial statements. Actual results could differ from those
     estimates.

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size tr
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     when acquired by the Fund are valued at amortized cost, which approximates
     market value. If the Fund acquires a short-term instrument with more than
     sixty days remaining to its maturity, it is valued at current market value
     until the sixtieth day prior to maturity and will then be valued at
     amortized value based upon the value on such date unless the Trustees
     determine during such sixty-day period that amortized value does not
     represent fair value.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Interest income
     is determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method on
     long-term debt securities. Dividend income is recorded on the ex-dividend
     date. Realized gains and losses from securities sold are recorded on the
     identified cost basis. The Fund does not isolate that portion of the
     results of operations resulting from changes in foreign exchange rates on
     investments from the fluctuations arising from changes in market prices of
     securities held. Such fluctuations are included with the net realized and
     unrealized gain or loss from investments. Net realized gains and losses on
     foreign currency transactions represent gains and losses on disposition of
     foreign currencies and forward foreign currency exchange contracts,
     currency gains and 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 the Fund's
     books and the U.S. dollar equivalent amounts usually received or paid.

     C. FOREIGN CURRENCY TRANSACTIONS

     Investment security valuations, other assets, and liabilities initially
     expressed in foreign currencies are converted into U.S. dollars based upon
     current currency exchange rates. Purchases and sales of foreign investment
     securities and income and expenses are converted into U.S. dollars based
     upon currency exchange rates prevailing on the respective dates of such
     transactions.

     Section 988 of the Internal Revenue Code provides that gains or losses on
     certain transactions attributable to fluctuations in foreign currency
     exchange rates must be treated as ordinary income or loss. For financial
     statement purposes, such amounts are included in net realized gains or
     losses.

     D. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. Dividends from net investment income and
     distributions from capital gains, if any, are reinvested in additional
     shares of the Fund unless the shareholder elects to receive them in cash.
     Income and capital gain distributions are determined in accordance with
     income tax regulations which may differ from generally accepted accounting
     principles. These differences, which may result in distribution
     reclassifications, are primarily due to differing treatments for losses
     deferred due to wash sales, capital loss carryforwards, foreign currency,
     and amortization and/or accretion of premiums and discounts on certain
     securities.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications among undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments and foreign currency transactions may include
     temporary book and tax basis differences which will reverse in a subsequent
     period. Any taxable income or gain remaining at fiscal year end is
     distributed in the following year.

     E. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expense and the relative size of the funds.

     F. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Fund may enter into contracts and
     agreements that contain a variety of representations and warranties, which
     provide general indemnifications. The maximum exposure to the Fund under
     these arrangements is unknown, as this would involve future claims that may
     be made against the Fund that have not yet occurred. However, based on
     experience, the Fund expects the risks of loss to be remote.

     G. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by Standish Mellon Asset Management Company LLC ("Standish Mellon")
     or its affiliates.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to Standish Mellon, a wholly-owned
     subsidiary of Mellon Financial Corporation, for overall investment advisory
     and administrative services, and general office facilities, is paid monthly
     at the annual rate of 0.40% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit total Fund operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     0.10% of the Fund's average daily net assets for the period ended June 30,
     2004. Pursuant to this agreement, for the period ended June 30, 2004,
     Standish Mellon voluntarily did not impose $76,890 of its investment
     advisory fee and reimbursed the Fund for $48,419 of its operating expenses.
     This agreement is voluntary and temporary and may be discontinued or
     revised by Standish Mellon at any time.

     As of February 23, 2004, the Fund compensates Dreyfus Transfer, Inc., a
     wholly owned subsidiary of Dreyfus, Which is an affiliate of Standish
     Mellon, under a transfer agency agreement for providing personnel and
     facilities to perform transfer agency services for the Fund. Pursuant to
     this agreement the Fund was charged $2,361 during the period ended June 30,
     2004 and $2,361 was owed at June 30, 2004.

     The Fund compensates Mellon Bank, N.A., under a custody, administration and
     accounting services agreement for providing custody, fund administration
     and fund accounting services for the fund. Pursuant to this agreement the
     Fund was charged $28,458 during the period ended June 30, 2004 and $9,745
     was owed at June 30, 2004.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(4)  SHARES OF BENEFICIAL INTEREST:

     The Declaration of Trust permits the Trustees to issue an unlimited number
     of full and fractional shares of beneficial interest having a par value of
     one cent per share. Transactions in Fund shares were as follows:

     At June 30, 2004, three shareholders of record held approximately 28%, 24%
     and 12% of the total outstanding shares of the Fund. All of the Fund's
     shares are beneficially owned by fiduciary accounts over which Standish
     Mellon and its affiliates have either sole or joint investment discretion.
     Investment activity of these shareholders could have a material impact on
     the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at June 30, 2004, as computed on a federal
     income tax basis, were as follows:

(6)  FINANCIAL INSTRUMENTS:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved. The
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     The Fund may trade the following instruments with off-balance sheet risk:

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Fund may use options to seek to hedge against risks of
     market exposure and changes in securities prices and foreign currencies, as
     well as to seek to enhance returns. Writing puts and buying calls tend to
     increase the Fund's exposure to the underlying instrument. Buying puts and
     writing calls tend to decrease the Fund's exposure to the underlying
     instrument, or hedge other Fund investments. Options, both held and written
     by the Fund, are reflected in the accompanying Statement of Assets and
     Liabilities at market value. The underlying face amount at value of any
     open purchased options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     end. Losses may arise from changes in the value of the underlying
     instruments, if there is an illiquid secondary market for the contract or
     if the counterparty does not perform under the contract's terms.

     Premiums received from writing options which expire are treated as realized
     gains. Premiums received from writing options which are exercised or are
     closed are added to or offset against the proceeds or amount paid on the
     transaction to determine the realized gain or loss. Realized gains and
     losses on purchased options are included in realized gains and losses on
     investment securities, except purchased options on foreign currency which
     are included in realized gains and losses on foreign currency transactions.
     If a put option written by the Fund is exercised, the premium reduces the
     cost basis of the securities purchased by the Fund. The Fund, as writer of
     an option, has no control over whether the underlying securities may be
     sold (call) or purchased (put) and as a result bears the market risk of an
     unfavorable change in the price of the security underlying the written
     option.

     Exchange traded options are valued at the last sale price, or if no sales
     are reported, the last bid price for purchased options and the last ask
     price for written options. Options traded over-the-counter are valued using
     prices supplied by the dealers.

     The Fund entered into no such transactions during the period ended June 30,
     2004.

     FORWARD CURRENCY EXCHANGE CONTRACTS

     The Fund may enter into forward foreign currency and cross currency
     exchange contracts for the purchase or sale of a specific foreign currency
     at a fixed price on a future date. Risks may arise upon entering these
     contracts from the potential inability of counterparties to meet the terms
     of their contracts and from unanticipated movements in the value of a
     foreign currency relative to the U.S. dollar and other foreign currencies.
     The forward foreign currency and cross currency exchange contracts are
     marked to market using the forward foreign currency rate of the underlying
     currency and any gains or losses are recorded for financial statement
     purposes as unrealized until the contract settlement date or upon the
     closing of the contract. Forward currency exchange contracts are used by
     the Fund primarily to protect the value of the Fund's foreign securities
     from adverse currency movements. Unrealized appreciation and depreciation
     of forward currency exchange contracts is included in the Statement of
     Assets and Liabilities.

     At June 30, 2004, the Fund held the following forward foreign currency
     exchange contracts:

     SWAP AGREEMENTS

     The Fund may invest in swap agreements. A swap is an agreement to exchange
     the return generated by one instrument for the return generated by another
     instrument. The Fund may enter into interest rate and credit default swap
     agreements to manage its exposure to interest rates and credit risk.
     Interest rate swap agreements involve the exchange by the Fund with another
     party of their respective commitments to pay or receive interest, e.g., an
     exchange of floating rate payments for fixed rate payments with respect to
     a notional amount of principal. In a credit default swap, one party makes a
     stream of payments to another party in exchange for the right to receive a

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

     specified return in the event of a default by a third party on its
     obligation. The Fund may use credit default swaps to provide a measure of
     protection against defaults of issuers (i.e., to reduce risk where the Fund
     owns or has exposure to the corporate or sovereign issuer) or to take an
     active long or short position with respect to the likelihood of a
     particular corporate or sovereign issuer's default. In connection with
     these agreements, cash or securities may be set aside as collateral in
     accordance with the terms of the swap agreement. The Fund earns interest on
     cash set aside as collateral. Swaps are marked to market daily based upon
     quotations from market makers and change in value, if any, is recorded as
     unrealized gain or loss in the Statement of Operations. These financial
     instruments are not actively traded on financial markets. The values
     assigned to these instruments are based upon the best available information
     and because of the uncertainty of the valuation, these values may differ
     significantly from the values that would have been realized had a ready
     market for these instruments existed, and differences could be material.
     Payments received or made from credit default swaps at the end of the
     measurement period are recorded as realized gain or loss in the Statement
     of Operations. Net payments of interest on interest rate swap agreements
     are included as part of interest income. Entering into these agreements, if
     any, involves, to varying degrees, elements of credit, market, and
     documentation risk in excess of the amounts recognized on the Statement of
     Assets and Liabilities. Such risks involve the possibility that there will
     be no liquid market for these agreements, that the counterparty to the
     agreements may default on its obligation to perform or disagree as to the
     meaning of contractual terms in the agreements, and that there may be
     unfavorable changes in interest rates.

     At June 30, 2004, the Fund held no credit default swap contracts.

     FUTURES CONTRACTS

     The Fund may enter into financial futures contracts for the delayed sale or
     delivery of securities or contracts based on financial indices at a fixed
     price on a future date. Pursuant to the margin requirements, the Fund
     deposits either cash or securities in an amount equal to a certain
     percentage of the contract amount. Subsequent payments are made or received
     by the Fund each day, depending on the daily fluctuations in the value of
     the underlying security, and are recorded for financial statement purposes
     as unrealized gains or losses by the Fund. There are several risks in
     connection with the use of futures contracts as a hedging device. The
     change in value of futures contracts primarily corresponds with the value
     of their underlying instruments or indices, which may not correlate with
     changes in the value of hedged investments. Buying futures tends to
     increase the Fund's exposure to the underlying instrument, while selling
     futures tends to decrease the Fund's exposure to the underlying instrument
     or hedge other Fund investments. In addition, there is the risk that the
     Fund may not be able to enter into a closing transaction because of an
     illiquid secondary market. Losses may arise if there is an illiquid
     secondary market or if the counterparties do not perform under the
     contract's terms. The Fund enters into financial futures transactions
     primarily to manage its exposure to certain markets and to changes in
     securities prices and foreign currencies. Gains and losses are realized
     upon the expiration or closing of the futures contracts. Futures contracts
     are valued at the quoted daily settlement prices established by the
     exchange on which they trade.

     The Fund entered into no such transactions during the period ended June 30,
     2004.

(7)  SECURITY LENDING:

     The Fund may lend its securities to financial institutions which the Fund
     deems to be creditworthy. The loans are collateralized at all times with
     cash or securities with a market value at least equal to the market value
     of the securities on loan. The market value of securities loaned is
     determined daily and any additional required collateral is allocated to the
     Fund on the next business day. For the duration of a loan, the Fund
     receives the equivalent of the interest or dividends paid by the issuer on
     the securities loaned and also receives compensation from the investment of
     the collateral. As with other extensions of credit, the Fund bears the risk
     of delay in recovery or even loss of rights in its securities on loan
     should the borrower of the securities fail financially or default on its
     obligations to the Fund. In the event of borrower default, the Fund
     generally has the right to use the collateral to offset losses incurred.
     The Fund may incur a loss in the event it was delayed or prevented from
     exercising its rights to dispose of the collateral. The Fund also bears the
     risk in the event that the interest and/or dividends received on invested
     collateral is not sufficient to meet the Fund's obligations due on the
     loans.

     The Fund loaned securities during the period ended June 30, 2004 resulting
     in $3,345 of security lending income. At June 30, 2004 the Fund had
     $4,800,499 worth of securities on loan.

     See the Statement of Investments for further detail on the security
     positions on loan.

(8)  DELAYED DELIVERY TRANSACTIONS:

     The Fund may purchase or sell securities on a when-issued, delayed delivery
     or forward commitment basis. This Fund segregates securities having a value
     at least equal to the amount of the purchase commitment.

     The Fund may enter into to be announced ("TBA") purchase commitments to
     purchase securities for a fixed unit price at a future date beyond
     customary settlement time. Although the unit price has been established,
     the principal value has not been finalized. However, the amount of the
     commitments will not fluctuate more than 0.01% from the principal amount.
     The Fund holds, and maintains until settlement date, cash or high-grade
     debt obligations in an amount sufficient to meet the purchase price, or the
     Fund may enter into offsetting contracts for the forward sale of other
     securities it owns. Income on the securities will not be earned until
     settlement date. TBA purchase commitments may be considered securities in
     themselves, and involve a risk of loss if the value of the security to be
     purchased declines prior to the settlement date, which risk is in addition
     to the risk of the decline in the value of the Fund's other assets.
     Unsettled TBA purchase commitments are valued at the current market value
     of the underlying securities, according to the procedures described under
     "Investment security valuations" above.

     The Fund may enter into TBA sale commitments to hedge its portfolio
     positions. Proceeds of TBA sale commitments are not received until the
     contractual settlement date. During the time a TBA sale commitment is
     outstanding, an offsetting TBA purchase commitment deliverable is held as
     "cover" for the transaction.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Fund as an unrealized gain or loss. If the TBA sale commitment is closed
     through the acquisition of an offsetting purchase commitment, the Fund
     realizes a gain or loss from the sale of the securities based upon the unit
     price established at the date the commitment was entered into.

     The Fund entered into no such transactions during the period ended June 30,
     2004.

(9)  CONCENTRATION OF RISK:

     The Fund invests in low rated (non-investment grade) and comparable quality
     unrated high yield securities. Investments in high yield securities are
     accompanied by a greater degree of credit risk and the value of high yield
     securities tends to be more sensitive to economic conditions than higher
     rated securities. The risk of loss due to default of an issuer may be
     significantly greater for holders of high yield securities, because such
     securities are generally unsecured and are often subordinated to other
     creditors of the issuer.

(10)   LINE OF CREDIT:

     The Fund, and other subtrusts in the Portfolio Trust and funds in the Trust
     are parties to a committed line of credit facility, which enables each
     portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is
     charged to each participating portfolio/fund based on its borrowings at a
     rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition,
     a commitment fee, computed at an annual rate of .060 of 1% on the daily
     unused portion of the facility, is allocated ratably among the
     participating portfolios/funds at the end of each quarter.

     For the period ended June 30, 2004, the expense related to the commitment
     fee was $150 for the Fund.

     During the period ended June 30, 2004, the Fund had not borrowed under the
     credit facility.

     Companies effective January 1, 2001 and began amortizing premium and
     discount on all debt securities on an effective yield basis. The effect of
     this change for the year ended December 31, 2001 was to increase net
     investment income per share by $0.001, decrease net realized and unrealized
     gains and losses per share by $0.001 and increase the ratio of net
     investment income to average net assets by less than 0.01%. Per share data

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                 STANDISH MELLON SHORT-TERM ASSET RESERVE FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon Short-Term Asset Reserve Fund (the "Fund") is a separate
     diversified investment series of the Trust.

     The objective of the Fund is to achieve a high level of current income
     consistent with preserving principal and liquidity. The Fund seeks to
     achieve its objective by investing all of its investable assets in an
     interest of the Standish Mellon Short-Term Asset Reserve Portfolio (the
     "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio
     (the "Portfolio Trust"), which is organized as a New York trust and which
     has the same investment objective as the Fund. The Portfolio seeks to
     achieve its objective by investing, under normal circumstances, at least
     80% of net assets in dollar-denominated money market instruments,
     short-term fixed income securities and asset-backed securities of U.S. and
     foreign governments, banks and companies. The value of the Fund's
     investment in the Portfolio reflects the Fund's proportionate interest in
     the net assets of the Portfolio (approximately 100% at June 30, 2004). The
     performance of the Fund is directly affected by the performance of the
     Portfolio. The financial statements of the Portfolio are included elsewhere
     in this report and should be read in conjunction with the Fund's financial
     statements.

     The following is a summary of significant accounting policies followed by
     the Fund in the preparation of its financial statements. The preparation of
     financial statements in accordance with accounting principles generally
     accepted in the United States of America requires management to make
     estimates and assumptions that affect the reported amounts and disclosures
     in the financial statements. Actual results could differ from those
     estimates.

     A. INVESTMENT SECURITY VALUATIONS

     The Fund records its investment in the Portfolio at value. The method by
     which the Portfolio values its securities is discussed in Note 1A of the
     Portfolio's Notes to Financial Statements, which are included elsewhere in
     this report.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Currently, the
     Fund's net investment income consists of the Fund's pro rata share of the
     net investment income of the Portfolio, less all actual and accrued
     expenses of the Fund determined in accordance with accounting principles
     generally accepted in the United States of America. All realized and
     unrealized gains and losses of the Portfolio are allocated pro rata among
     the investors in the Portfolio.

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared daily and distributed
     monthly. The Fund's dividends from short-term and long-term capital gains,
     if any, after reduction of capital losses will be declared and distributed
     at least annually. In determining the amounts of its dividends, the Fund
     will take into account its share of the income, gains or losses, expenses,
     and any other tax items of the Portfolio. Dividends from net investment
     income and distributions from capital gains, if any, are reinvested in
     additional shares of the Fund unless a shareholder elects to receive them
     in cash. Income and capital gain distributions are determined in accordance
     with income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in distribution reclassifications, are primarily due to
     differing treatments for capital loss carryforwards and amortization and/or
     accretion of premiums and discounts on certain securities.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications to undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments and foreign currency transactions may include
     temporary book and tax basis differences which will reverse in a subsequent
     period. Any taxable income or gain remaining at fiscal year end is
     distributed in the following year.

     D. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expense and the relative size of the funds.

     E. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Fund may enter into contracts and
     agreements that contain a variety of representations and warranties, which
     provide general indemnifications. The maximum exposure to the Fund under
     these arrangements is unknown, as this would involve future claims that may
     be made against the Fund that have not yet occurred. However, based on
     experience, the Fund expects the risks of loss to be remote.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(2)  INVESTMENT ADVISORY FEE AND TRANSACTIONS WITH AFFILIATES:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary of Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report. Standish Mellon voluntarily agreed to
     limit the total operating expenses of the Fund and its pro rata share of
     the Portfolio expenses (excluding brokerage commissions, taxes and
     extraordinary expenses) to 0.45% of the Fund's average daily net assets for
     the period ended June 30, 2004. This agreement is voluntary and temporary
     and may be discontinued or revised by Standish Mellon at any time.

     On February 23, 2004, the Fund entered into an agreement with Dreyfus
     Transfer, Inc., a wholly owned subsidiary of Dreyfus, which is an affiliate
     of Standish Mellon, to provide transfer agent services to the Fund.
     Pursuant to this agreement the Fund was charged $2,701 during the period
     ended June 30, 2004 and $2,701 was owed at June 30, 2004.

     The Portfolio compensates Mellon Bank, N.A. under a administration and
     accounting services agreement for providing fund administration and fund
     accounting services for the Portfolio.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     period ended June 30, 2004, aggregated $52,946,871 and $126,082,112,
     respectively.

(4)  SHARES OF BENEFICIAL INTEREST:

     The Declaration of Trust permits the Trustees to issue an unlimited number
     of full and fractional shares of beneficial interest having a par value of
     one cent per share. Transactions in Fund shares were as follows:



                                                                      PERIOD ENDED

     At June 30, 2004, one shareholder of record held approximately 14% and of
     the total outstanding shares of the Fund. Investment activity of these
     shareholders could have a material impact on the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

               STANDISH MELLON SHORT-TERM ASSET RESERVE PORTFOLIO

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
     organized as a master trust fund under the laws of the State of New York on
     January 18, 1996 and is registered under the Investment Company Act of
     1940, as amended, as an open-end, management investment company. Standish
     Mellon Short-Term Asset Reserve Portfolio (the "Portfolio") is a separate
     diversified investment series of the Portfolio Trust.

     At June 30, 2004 there was one fund, Standish Mellon Short-Term Asset
     Reserve Fund (the "Fund"), invested in the Portfolio. The value of the
     Fund's investment in the Portfolio reflects the Fund's proportionate
     interest in the net assets of the Portfolio. The Fund's proportionate
     interest at June 30, 2004 was approximately 100%.

     The objective of the Portfolio is to achieve a high level of current income
     consistent with preserving principal and liquidity. The Portfolio seeks to
     achieve its objective by investing, under normal circumstances, at least
     80% of net assets in dollar-denominated money market instruments,
     short-term fixed income securities and asset-backed securities of U.S. and
     foreign governments, banks and companies.

     The following is a summary of significant accounting policies followed by
     the Portfolio in the preparation of its financial statements. The
     preparation of financial statements in accordance with accounting
     principles generally accepted in the United States of America requires
     management to make estimates and assumptions that affect the reported
     amounts and disclosures in the financial statements. Actual results could
     differ from those estimates.

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are normally traded. Market
     quotations are not considered to be readily available for certain debt
     obligations, such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     when acquired by the Portfolio are valued at amortized cost, which
     approximates market value. If the Portfolio acquires a short-term
     instrument with more than sixty days remaining to its maturity, it is
     valued at current market value until the sixtieth day prior to maturity and
     will then be valued at amortized value based upon the value on such date
     unless the Trustees determine during such sixty-day period that amortized
     value does not represent fair value.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method on
     long-term debt securities. Realized gains and losses from securities sold
     are recorded on the identified cost basis.

     C. INCOME TAXES

     The Portfolio is treated as a partnership for federal tax purposes. No
     provision is made by the Portfolio for federal or state taxes on any
     taxable income of the Portfolio because each investor in the Portfolio is
     ultimately responsible for the payment of any taxes. Since at least one of
     the Portfolio's investors is a regulated investment company that invests
     all or substantially all of its assets in the Portfolio, the Portfolio
     normally must satisfy the source of income and diversification requirements
     applicable to regulated investment companies (under the Internal Revenue
     Code) in order for its investors to satisfy them. The Portfolio allocates
     at least annually among its investors each investor's distributive share of
     the Portfolio's net investment income, net realized capital gains, and any
     other items of income, gain, loss deduction or credit.

     D. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Portfolio may enter into contracts
     and agreements that contain a variety of representations and warranties,
     which provide general indemnifications. The maximum exposure to the
     Portfolio under these arrangements is unknown, as this would involve future
     claims that may be made against the Portfolio that have not yet occurred.
     However, based on experience, the Portfolio expects the risks of loss to be
     remote.

     E. AFFILIATED ISSUERS

     Issuers in which the Portfolio held investments in other investment
     companies advised by Standish Mellon Asset Management Company LLC
     ("Standish Mellon") or its affiliates.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services is paid monthly at the annual rate of
     0.25% of the Portfolio's average daily net assets.

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio was charged $47,089 during the period ended
     June 30, 2004 and was owed $3,978 at June 30, 2004.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the Trustees.

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the period ended June 30, 2004 were as follows:

(4)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

(5)  FINANCIAL INSTRUMENTS:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved. The
     nature, risks and objectives of these instruments are set forth more fully
     in the Portfolio Trust's registration statement.

     The Portfolio may trade the following financial instruments with
     off-balance sheet risk:

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Portfolio may use options to seek to hedge against
     risks of market exposure and changes in security prices and foreign
     currencies, as well as to seek to enhance returns. Writing puts and buying
     calls tend to increase the Portfolio's exposure to the underlying
     instrument. Buying puts and writing calls tend to decrease the Portfolio's
     exposure to the underlying instrument, or hedge other Portfolio
     investments. Options, both held and written by the Portfolio, are reflected
     in the accompanying Statement of Assets and Liabilities at market value.
     The underlying face amount at value of any open purchased options is shown
     in the Schedule of Investments. This amount reflects each contract's
     exposure to the underlying instrument at period end. Losses may arise from
     changes in the value of the underlying instruments if there is an illiquid
     secondary market for the contract or if the counterparty does not perform
     under the contract's terms.

     Premiums received from writing options which expire are treated as realized
     gains. Premiums received from writing options which are exercised or are
     closed are added to or offset against the proceeds or amount paid on the
     transaction to determine the realized gain or loss. Realized gains and
     losses on purchased options are included in realized gains and losses on
     investment securities, except purchased options on foreign currency which
     are included in realized gains and losses on foreign currency transactions.
     If a put option written by the Portfolio is exercised, the premium reduces
     the cost basis of the securities purchased by the Portfolio. The Portfolio,
     as a writer of an option, has no control over whether the underlying
     securities may be sold (call) or purchased (put) and as a result bears the
     market risk of an unfavorable change in the price of the security
     underlying the written option.

     Exchange traded options are valued at the last sale price, or if no sales
     are reported, the last bid price for purchased options and the last ask
     price for written options. Options traded over-the-counter are valued using
     prices supplied by the dealers.

     The Portfolio entered into no such transactions during the period ended
     June 30, 2004.

     INTEREST RATE FLOORS

     Interest rate floors purchased by the Portfolio entitle the Portfolio to
     receive payments on a notional principal amount from the party selling such
     floor to the extent that a specified index falls below a predetermined
     interest rate amount. Credit and market risk exist with respect to these
     instruments. If forecasts of interest rates and other market factors are
     incorrect, investment performance will diminish compared to what
     performance would have been if these investment techniques were not used.
     Even if the forecasts are correct, there are risks that the positions may
     correlate imperfectly with the asset or liability being hedged, a liquid
     secondary market may not always exist, or a counterparty to a transaction
     may not perform. The Portfolio expects to enter these transactions
     primarily for hedging purposes including, but not limited to, preserving a
     return or spread on a particular investment or portion of its portfolio,
     protecting against currency fluctuations, as a duration management
     technique or protecting against an increase in the price of securities the
     Portfolio anticipates purchasing at a later date. Interest rate floors are
     "marked-to-market" daily based on quotations from market makers and the
     change, if any, is recorded as unrealized appreciation or depreciation in
     the Statement of Operations. Periodic payments of interest, if any, are
     reported as additions to interest income in the Statement of Operations.
     Realized gains or losses from these agreements are disclosed in the
     Statement of Operations.

     At June 30, 2004, the Portfolio did not hold any open interest rate floor
     agreements.

     FUTURES CONTRACTS

     The Portfolio may enter into financial futures contracts for the delayed
     sale or delivery of securities or contracts based on financial indices at a
     fixed price on a future date. Pursuant to margin requirements the Portfolio
     deposits either cash or securities in an amount equal to a certain
     percentage of the contract amount. Subsequent payments are made or received
     by the Portfolio each day, depending on the daily fluctuations in the value
     of the underlying security, and are recorded for financial statement
     purposes as unrealized gains or losses by the Portfolio. There are several
     risks in connection with the use of futures contracts as a hedging device.
     The change in value of futures contracts primarily corresponds with the
     value of their underlying instruments or indices, which may not correlate
     with changes in the value of hedged investments. Buying futures tends to
     increase the Portfolio's exposure to the underlying instrument, while
     selling futures

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

     tends to decrease the Portfolio's exposure to the underlying instrument or
     hedge other investments. In addition, there is the risk that the Portfolio
     may not be able to enter into a closing transaction because of an illiquid
     secondary market. Losses may arise if there is an illiquid secondary market
     or if the counterparty does not perform under the contract's terms. The
     Portfolio enters into financial futures transactions primarily to seek to
     manage its exposure to certain markets and to changes in securities prices
     and foreign currencies. Gains and losses are realized upon the expiration
     or closing of the futures contracts. Futures contracts are valued at the
     quoted daily settlement prices established by the exchange on which they
     trade.

     At June 30, 2004, the Portfolio held the following financials futures
     contracts:



                                                                          UNDERLYING FACE         UNREALIZED

     At June 30, 2004, the Portfolio had segregated sufficient cash and/or
     securities to cover margin requirements on open futures contracts.

(6)  SECURITY LENDING:

     The Portfolio may lend its securities to financial institutions which the
     Portfolio deems to be creditworthy. The loans are collateralized at all
     times with cash or securities with a market value at least equal to the
     market value of the securities on loan. The market value of securities
     loaned is determined daily and any additional required collateral is
     allocated to the Portfolio on the next business day. For the duration of a
     loan, the Portfolio receives the equivalent of the interest or dividends
     paid by the issuer on the securities loaned and also receives compensation
     from the investment of the collateral. As with other extensions of credit,
     the Portfolio bears the risk of delay in recovery or even loss of rights in
     its securities on loan should the borrower of the securities fail
     financially or default on its obligations to the Portfolio. In the event of
     borrower default, the Portfolio generally has the right to use the
     collateral to offset losses incurred. The Portfolio may incur a loss in the
     event it was delayed or prevented from exercising its rights to dispose of
     the collateral. The Portfolio also bears the risk in the event that the
     interest and/or dividends received on invested collateral is not sufficient
     to meet the Portfolio's obligations due on the loans.

     The Portfolio loaned securities during the period ended June 30, 2004
     resulting in $776 of security lending income. At June 30, 2004, the
     Portfolio had $699,896 worth of securities on loan.

     See the Statement of Investments for further detail on the security
     positions on loan.

(7)  DELAYED DELIVERY TRANSACTIONS:

     The Portfolio may purchase securities on a when-issued, delayed delivery or
     forward commitment basis. Payment and delivery may take place a month or
     more after the date of the transactions. 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. Income on the
     securities will not be earned until settlement date. The Portfolio
     instructs its custodian to segregate securities having value at least equal
     to the amount of the purchase commitment.

     The Portfolio may enter into to be announced ("TBA") purchase commitments
     to purchase securities for a fixed unit price at a future date beyond
     customary settlement time. Although the unit price has been established,
     the principal value has not been finalized. However, the amount of the
     commitments will not fluctuate more than 0.01% from the principal amount.
     The Portfolio holds, and maintains until settlement date, cash or
     high-grade debt obligations in an amount sufficient to meet the purchase
     price, or the Portfolio may enter into offsetting contracts for the forward
     sale of other securities it owns. Income on the securities will not be
     earned until settlement date. TBA purchase commitments may be considered
     securities in themselves, and involve a risk of loss if the value of the
     security to be purchased declines prior to the settlement date, which risk
     is in addition to the risk of the decline in the value of the Portfolio's
     other assets. Unsettled TBA purchase commitments are valued at the current
     market value of the underlying securities, according to the procedures
     described under "Investment security valuations" above.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

     The Portfolio may enter into TBA sale commitments to hedge its portfolio
     positions. Proceeds of TBA sale commitments are not received until the
     contractual settlement date. During the time a TBA sale commitment is
     outstanding, an offsetting TBA purchase commitment deliverable is held as
     "cover" for the transaction.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Portfolio as an unrealized gain or loss. If the TBA sale commitment is
     closed through the acquisition of an offsetting purchase commitment, the
     Portfolio realizes a gain or loss from the sale of the securities based
     upon the unit price established at the date the commitment was entered
     into.

     At June 30, 2004, the Portfolio did not have any delayed delivery
     transactions.

(8)  LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
     Trust are parties to a committed line of credit facility, which enables
     each portfolio/fund to borrow, in the aggregate, up to $35 million.
     Interest is charged to each participating portfolio/fund based on its
     borrowings at a rate equal to the Federal Funds effective rate plus 1-2 of
     1%. In addition, a commitment fee, computed at an annual rate of 0.060 of
     1% on the daily unused portion of the facility, is allocated ratably among
     the participating portfolios/funds at the end of each quarter.

     For the period ended June 30, 2004, the expense related to the commitment
     fee was $428 for the Portfolio.

     During the period ended June 30, 2004, the Portfolio had not borrowed under
     the credit facility.

(a) The Fund has adopted the provisions of the revised AICPA Audit and
    Accounting Guide for Investment Companies effective January 1, 2001 and
    began amortizing premium and discount on all debt securities on an
    effective yield basis. The effect of this change for the year ended
    December 31, 2001 was to increase net investment income per share by less
    than $0.001, decrease net realized and unrealized gains and losses per
    share by less than $0.001 and increase the ratio of net investment income
    to average net assets by less than 0.01%. Per share data and
    ratios/supplemental data for the periods prior to January 1, 2001 have not
    been restated to reflect this change in presentation.

(1) Calculated based on average shares outstanding,

(2) The amount shown for a share outstanding does not correspond with the
    aggregate net realized and unrealized gain/loss for the period due to the
    timing of purchases and redemptions of Fund shares in relation to the
    fluctuating market values of the Fund.

+   Total return would have been lower in the absence of expense waivers.

++  Not annualized.

+++ Computed on an annualized basis using a 366 day calendar year.

                  STANDISH MELLON SHORT-TERM FIXED INCOME FUND

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon Short-Term Fixed Income Fund (the "Fund") is a separate
     diversified investment series of the Trust.

     The objective of the Fund is to maximize total return, consistent with
     preserving principal and liquidity, while seeking a relatively high level
     of current income. The Fund seeks to achieve its objective by investing,
     under normal circumstances, at least 80% of net assets in fixed income
     securities of U.S. companies and the U.S. government.

     The following is a summary of significant accounting policies followed by
     the Fund in the preparation of its financial statements. The preparation of
     financial statements in accordance with accounting principles generally
     accepted in the United States of America requires management to make
     estimates and assumptions that affect the reported amounts and disclosures
     in the financial statements. Actual results could differ from those
     estimates.

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     when acquired by the Fund are valued at amortized cost, which approximates
     market value. If the Fund acquires a short-term instrument with more than
     sixty days remaining to its maturity, it is valued at current market value
     until the sixtieth day prior to maturity and will then be valued at
     amortized value based upon the value on such date unless the Trustees
     determine during such sixty-day period that amortized value does not
     represent fair value.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Interest income
     is determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method on
     debt securities. Realized gains and losses from securities sold are
     recorded on the identified cost basis.

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income and distributions from capital gains,
     if any, are reinvested in additional shares of the Fund unless a
     shareholder elects to receive them in cash. Income and capital gain
     distributions are determined in accordance with income tax regulations
     which may differ from accounting principles generally accepted in the
     United States of America. These differences, which may result in
     distribution reclassifications, are primarily due to differing treatments
     of amortization and/or accretion of premiums and discounts on certain
     securities and paydown gains and losses.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications among undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments may include temporary book and tax basis
     differences which will reverse in a subsequent period. Any taxable income
     or gain remaining at fiscal year end is distributed in the following year.

     D. EXPENSES

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration, among other things, the
     nature and type of expenses and the relative size of the funds.

     E. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Fund may enter into contracts and
     agreements that contain a variety of representations and warranties which
     provide general indemnifications. The maximum exposure to the Fund under
     these arrangements is unknown, as this would involve future claims that may
     be made against the Fund that have not yet occurred. However, based on
     experience, the Fund expects the risks of loss to be remote.

     F. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by Standish Mellon Asset Management Company LLC ("Standish Mellon")
     or its affiliates.

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to Standish Mellon, a wholly-owned
     subsidiary of Mellon Financial Corporation, for overall investment
     advisory, administrative services, and general office facilities, is paid
     monthly at the annual rate of 0.30% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit total Fund operating expenses

     At June 30, 2004, two shareholders of record held approximately 57% and 24%
     of the total outstanding shares of the Fund.

     A significant portion of the Fund's shares are beneficially owned by

     either sole or joint investment discretion. Investment activity of these
     shareholders could have a material impact on the Fund.

(6)  FINANCIAL INSTRUMENTS:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved. The
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     The Fund may trade the following instruments with off-balance sheet risk:

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Fund may use options to seek to hedge against risks of
     market exposure and changes in securities prices and foreign currencies, as
     well as to seek to enhance returns. Writing puts and buying calls tend to
     increase the Fund's exposure to the underlying instrument. Buying puts and
     writing calls tend to decrease the Fund's exposure to the underlying
     instrument, or hedge other Fund investments. Options, both held and written
     by the Fund, are reflected in the accompanying Statement of Assets and
     Liabilities at market value. The underlying face amount at value of any
     open purchased options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     end. Losses may arise from changes in the value of the underlying
     instruments, if there is an illiquid secondary market for the contract or
     if the counterparty does not perform under the contract's terms

     Premiums received from writing options which expire are treated as realized
     gains. Premiums received from writing options which are exercised or are
     closed are added to or offset against the proceeds or amount paid on the
     transaction to determine the realized gain or loss. Realized gains and
     losses on purchased options are included in realized gains and losses on
     investment securities, except purchased options on foreign currency which
     are included in realized gains and losses on foreign currency transactions.
     If a put option written by the Fund is exercised, the premium reduces the
     cost basis of the securities purchased by the Fund. The Fund, as writer of
     an option, has no control over whether the underlying securities may be
     sold (call) or purchased (put) and as a result bears the market risk of an
     unfavorable change in the price of the security underlying the written
     option.

     Exchange traded options are valued at the last sale price, or if no sales
     are reported, the last bid price for purchased options and the last ask
     price for written options. Options traded over-the-counter are valued using
     prices supplied by the dealers.

     The Fund entered into no such transactions during the period ended June 30,
     2004.

     FUTURES CONTRACTS

     The Fund may enter into financial futures contracts for the delayed sale or
     delivery of securities or contracts based on financial indices at a fixed
     price on a future date. Pursuant to the margin requirements, the Fund
     deposits either cash or securities in an amount equal to a certain
     percentage of the contract amount. Subsequent payments are made or received
     by the Fund each day, depending on the daily fluctuations in the value of
     the underlying security, and are recorded for financial statement purposes
     as unrealized gains or losses by the Fund. There are several risks in
     connection with the use of futures contracts as a hedging device. The
     change in value of futures contracts primarily corresponds with the value
     of their underlying instruments or indices, which may not correlate with
     changes in the value of hedged investments. Buying futures tends to
     increase the Fund's exposure to the underlying instrument, while selling
     futures tends to decrease the Fund's exposure to the underlying instrument
     or hedge other Fund investments. In addition, there is the risk that the
     Fund may not be able to enter into a closing transaction because of an
     illiquid secondary market. Losses may arise if there is an illiquid
     secondary market or if the counterparties do not perform under the
     contract's terms. The Fund enters into financial futures transactions

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

     primarily to manage its exposure to certain markets and to changes in
     securities prices and foreign currencies. Gains and losses are realized
     upon the expiration or closing of the futures contracts. Futures contracts
     are valued at the quoted daily settlement prices established by the
     exchange on which they trade.

     The Fund entered into no such transactions during the period ended June 30,
     2004.

(7)  SECURITY LENDING:

     The Fund may lend its securities to financial institutions which the Fund
     deems to be creditworthy. The loans are collateralized at all times with
     cash or securities with a market value at least equal to the market value
     of the securities on loan. The market value of securities loaned is
     determined daily and any additional required collateral is allocated to the
     Fund on the next business day. For the duration of a loan, the Fund
     receives the equivalent of the interest or dividends paid by the issuer on
     the securities loaned and also receives compensation from the investment of
     the collateral. As with other extensions of credit, the Fund bears the risk
     of delay in recovery or even loss of rights in its securities on loan
     should the borrower of the securities fail financially or default on its
     obligations to the Fund. In the event of borrower default, the Fund
     generally has the right to use the collateral to offset losses incurred.
     The Fund may incur a loss in the event it was delayed or prevented from
     exercising its rights to dispose of the collateral. The Fund also bears the
     risk in the event that the interest and/or dividends received on invested
     collateral is not sufficient to meet the Fund's obligations due on the
     loans.

     The Fund loaned securities during the period ended June 30, 2004 resulting
     in $487 of security lending income. At June 30, 2004, the Fund had $45,362
     worth of securities on loan.

     See the Statement of Investments for further detail on the security
     positions on loan.

(8)  DELAYED DELIVERY TRANSACTIONS:

     The Fund may purchase or sell securities on a when-issued, delayed delivery
     or forward commitment basis. The Fund segregates securities having a value
     at least equal to the amount of the purchase commitment.

     The Fund may enter into to be announced ("TBA") purchase commitments to
     purchase securities for a fixed unit price at a future date beyond
     customary settlement time. Although the unit price has been established,
     the principal value has not been finalized. However, the amount of the
     commitments will not fluctuate more than 0.01% from the principal amount.
     The Fund holds, and maintains until settlement date, cash or high-grade
     debt obligations in an amount sufficient to meet the purchase price, or the
     Fund may enter into offsetting contracts for the forward sale of other
     securities it owns. Income on the securities will not be earned until
     settlement date. TBA purchase commitments may be considered securities in
     themselves, and involve a risk of loss if the value of the security to be
     purchased declines prior to the settlement date, which risk is in addition
     to the risk of the decline in the value of the Fund's other assets.
     Unsettled TBA purchase commitments are valued at the current market value
     of the underlying securities, according to the procedures described under
     "Investment security valuations" above.

     The Fund may enter into TBA sale commitments to hedge its portfolio
     positions. Proceeds of TBA sale commitments are not received until the
     contractual settlement date. During the time a TBA sale commitment is
     outstanding, an offsetting TBA purchase commitment deliverable is held as
     "cover" for the transaction.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Fund as an unrealized gain or loss. If the TBA sale commitment is closed
     through the acquisition of an offsetting purchase commitment, the Fund
     realizes a gain or loss from the sale of the securities based upon the unit
     price established at the date the commitment was entered into.

     At June 30, 2004, the Fund did not have any delayed delivery transactions.

(9)  LINE OF CREDIT:

     The Fund, and other subtrusts in the Portfolio Trust and funds in the Trust
     are parties to a committed line of credit facility, which enables each
     portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is
     charged to each participating portfolio/fund based on its borrowings at a
     rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition,
     a commitment fee, computed at an annual rate of .060 of 1% on the daily
     unused portion of the facility, is allocated ratably among the
     participating portfolios/funds at the end of each quarter.

     For the period ended June 30, 2004, the expense related to the commitment
     fee was $10 for the Fund.

     During the period ended June 30, 2004, the Fund had not borrowed under the
     credit facility.
