*    For the periods indicated, the investment adviser voluntarily agreed not to
     impose all or a portion of its investment advisory fee and reimbursed the
     Fund for all or a portion of its operating expenses. If this voluntary
     action had not been taken, the investment income per share and ratios would
     have been:

(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
     $0.004, 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 6.02% to 6.00%. 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.
++   Not annualized.
+++  Total return would have been lower in the absence of expense waivers.

                  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 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.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Investment Grade Bond Fund was changed to Standish Mellon
      Investment Grade Bond Fund. In addition, the name of the Standish, Ayer &
      Wood Investment Trust was changed to Mellon Institutional Funds Investment
      Trust. The name changes for the Fund and the Trust are effective July 1,
      2003.

      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. REPURCHASE AGREEMENTS

      It is the policy of the Fund to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the Fund
      and the counterparty. Additionally, procedures have been established by
      the Fund to monitor on a daily basis, the market value and accrued
      interest of the repurchase agreement's underlying investments to ensure
      the existence of a proper level of collateral.

     C. 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.

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

     D. 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.

     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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
      Financial Corporation, for overall investment advisory and administrative

      At June 30, 2003, the Fund had segregated sufficient securities for open

     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 a 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, 2003, 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, 2003, the Fund held the following financials futures
      contracts:



                                                                        UNDERLYING FACE

(7)  SECURITIES LENDING:

      The Fund may lend its securities, through its agent Investors Bank & Trust
      Co., to financial institutions which Standish Mellon 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.

      At June 30, 2003, the Fund loaned securities having a market value of
      $11,703,762. The Fund received cash collateral of $11,967,837 which is
      invested, together with collateral of other Mellon Institutional funds, in
      high-grade short-term investments.

(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.

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

      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

            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, 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.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Opportunistic Emerging Markets Debt Fund was changed to Standish
      Mellon Opportunistic Emerging Markets Debt Fund. In addition, the name of
      the Standish, Ayer & Wood Investment Trust was changed to Mellon
      Institutional Funds Investment Trust. The name changes for the Fund and
      the Trust are effective July 1, 2003.

      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. REPURCHASE AGREEMENTS

      It is the policy of the Fund to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the Fund
      and the counterparty. Additionally, procedures have been established by
      the Fund to monitor on a daily basis, the market value and accrued
      interest of the repurchase agreement's underlying investments to ensure
      the existence of a proper level of collateral.

     C. 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

            STANDISH MELLON OPPORTUNISTIC EMERGING MARKETS DEBT FUND

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

      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.

     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. 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.

     G. 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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("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 six months ended June 30, 2003.
      Pursuant to this agreement, for the six months ended June 30, 2003,
      Standish Mellon voluntarily did not impose $17,184 of its investment
      advisory fee and reimbursed the Fund for $52,783 of its operating
      expenses. This agreement is voluntary and temporary and may be
      discontinued or revised by Standish Mellon at any time.

      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 six months ended June 30, 2003 were as follows:



                                                                       PURCHASES     SALES

(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:

(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 trades 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, 2003, the Fund held no written call 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.

      At June 30, 2003, the Fund held the following forward foreign currency or
      cross currency exchange 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 six months ended
      June 30, 2003.

(7)  SECURITIES LENDING:

      The Fund may lend its securities, through its agent Investors Bank & Trust
      Co., to financial institutions which Standish Mellon 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.

      At June 30, 2003, the Fund loaned securities having a market value of
      $125,736. The Fund received cash collateral of $128,950 which is invested,
      together with collateral of other Mellon Institutional funds, in
      high-grade short-term investments.

(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 six months ended
      June 30, 2003.

                  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 invests 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 Trust 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, preferreds 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, 2003). 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.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish High Yield Bond Fund was changed to Standish Mellon High Yield
      Bond Fund. In addition, the name of the Standish, Ayer & Wood Investment
      Trust was changed to Mellon Institutional Funds Investment Trust. The name
      changes for the Fund and the Trust are effective July 1, 2003.

      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.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                      STANDISH MELLON HIGH YIELD BOND FUND

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

      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. 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.

(2)  INVESTMENT ADVISORY FEE:

      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 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 six months ended June 30, 2003, Standish Mellon voluntarily reimbursed
      the Fund for $36,388 of its operating expenses.

      Effective January 28, 2003, the Fund began imposing 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. The fee does not apply to shares that were acquired
      through reinvestment of distributions. The redemption fee is applicable to
      shares of the Fund purchased on or after January 28, 2003. For the period
      ended June 30, 2003, the Fund received $722 in 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
      six months ended June 30, 2003 aggregated $8,858,959 and $4,193,656,
      respectively.

(4)  SHARES OF BENEFICIAL INTEREST:

                   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 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, preferreds and warrants.

      At June 30, 2003, 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, 2003 was approximately 100%.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish High Yield Bond Portfolio was changed to Standish Mellon High
      Yield Bond Portfolio. In addition, the name of the Standish, Ayer & Wood
      Master Portfolio was changed to Mellon Institutional Funds Master
      Portfolio. The name changes for the Portfolio and the Portfolio Trust are
      effective July 1, 2003.

      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. REPURCHASE AGREEMENTS

      It is the policy of the Portfolio to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the
      Portfolio and the counterparty. Additionally, procedures have been
      established by the Portfolio to monitor on a daily basis, the market value
      and accrued interest of the repurchase agreement's underlying investments
      to ensure the existence of a proper level of collateral.

     C. 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.

     D. 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.

     E. 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.

     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 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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("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 six months ended June 30, 2003. Pursuant
      to this agreement, for the six months ended June 30, 2003, Standish Mellon
      voluntarily did not impose $87,727 of its investment advisory fees. This
      agreement is voluntary and temporary and may be discontinued or revised by
      Standish Mellon at any time.

      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 six months ended June 30, 2003 were $27,411,276 and
      $20,194,813, respectively. For the six months ended June 30, 2003, the
      Portfolio did not purchase or sell any long-term U.S. government
      securities.

(4)  FEDERAL TAXES:

(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 Parts A and B of the Portfolio Trust's registration statement.

      The Portfolio trades 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

                                       23

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

      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 six months ended June 30,
      2003 is as follows:

      At June 30, 2003, the Portfolio held no written call option contracts.

     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.

     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 interest income. 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, 2003, the Portfolio held the following open credit default
      swap contracts:



         NOTIONAL AMOUNT         EXPIRATION                                                           NET UNREALIZED

                                               Agreement with Goldman Sachs Capital Market, dated
                                               4/16/03 to pay 0.46% per year times the notional
                                               amount. The Portfolio receives payment only upon a
                                               default event by JP Morgan Chase & Co., the notional
                                               amount times the difference between the par value and
                                               the then-market value of JP Morgan Chase & Co., 5.25%
             1,000,000 USD        6/20/08      due 5/30/07.                                              $(3,000)


(6)  SECURITIES LENDING:

      The Portfolio may lend its securities, through its agent Investors Bank &
      Trust Co., to financial institutions which Standish Mellon 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.

      At June 30, 2003, the Portfolio loaned securities having a market value of
      $5,529,223. The Portfolio received cash collateral of $5,677,980 which is
      invested together with collateral of other Mellon Institutional funds in
      high grade short-term investments.

(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, 2003, the Portfolio did not have any 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 .065 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 six months ended June 30, 2003, the expense related to the
      commitment fee was $941 for the Portfolio.

      During the six months ended June 30, 2003, the Portfolio had no borrowings
      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.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Opportunistic High Yield Fund was changed to Standish Mellon
      Opportunistic High Yield Fund. In addition, the name of the Standish,
      Ayer & Wood Investment Trust was changed to Mellon Institutional Funds
      Investment Trust. The name changes for the Fund and the Trust are
      effective July 1, 2003.

      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. REPURCHASE AGREEMENTS

      It is the policy of the Fund to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the Fund
      and the counterparty. Additionally, procedures have been established by
      the Fund to monitor on a daily basis, the market value and accrued
      interest of the repurchase agreement's underlying investments to ensure
      the existence of a proper level of collateral.

     C. 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

                                       11


                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                 STANDISH MELLON OPPORTUNISTIC HIGH YIELD FUND

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

      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.

     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. 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.

     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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("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 six months ended June 30, 2003. Pursuant to this agreement,
      for the six months ended June 30, 2003, Standish Mellon voluntarily did
      not impose $63,131 of its investment advisory fee and reimbursed the Fund
      for $72,464 of its operating expenses. This agreement is voluntary and
      temporary and may be discontinued or revised by Standish Mellon at any
      time.

      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 six months ended June 30, 2003 were $19,269,095 and
      $27,110,198, respectively. For the six months ended June 30, 2003, the
      Fund did not purchase or sell any long-term U.S. government securities.

(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, 2003, 4 shareholders held of record approximately 27%, 19%,
      17% and 11% 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, 2003, 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 trades 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 six months ended
      June 30, 2003.

     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.

     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, 2003, the Fund held the following credit default swap
      contracts:

                                              04/16/03 to pay 0.46% per year times the notional
                                              amount. The Fund receives payment only upon a
                                              default event by JP Morgan Chase & Co., the notional
                                              amount times the difference between the par value
                                              and the then-market value of JP Morgan Chase & Co.,
                                              5.25% due 05/30/07.


     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

                                       15

                 STANDISH MELLON OPPORTUNISTIC HIGH YIELD FUND

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

      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 six months ended
      June 30, 2003.

(7)  SECURITIES LENDING:

      The Fund may lend its securities, through its agent Investors Bank & Trust
      Co., to financial institutions which Standish Mellon 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.

      At June 30, 2003, the Fund loaned securities having a market value of
      $2,836,659. The Fund received cash collateral of $2,910,940 which is
      invested, together with collateral of other Mellon Institutional funds, in
      high-grade short-term investments.

(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 six months ended
      June 30, 2003.

(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.

     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, to 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

                    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 invests all of its investable assets in an interest of Standish
      Mellon Global Fixed Income Portfolio (the "Portfolio"), a subtrust 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 Trust 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, 2003). 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.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Global Fixed Income Fund was changed to Standish Mellon Global
      Fixed Income Fund. In addition, the name of the Standish, Ayer & Wood
      Investment Trust was changed to Mellon Institutional Funds Investment
      Trust. The name changes for the Fund and the Trust are effective July 1,
      2003.

      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

                                       5

      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.

     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:

      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 0.65% of the Fund's average daily net
      assets for the six months ended June 30, 2003. Pursuant to this agreement,
      for the six months ended June 30, 2003, Standish Mellon voluntarily
      reimbursed the Fund for $37,744 of its operating expenses. This agreement
      is voluntary and temporary and may be discontinued or revised by Standish
      Mellon at any time.

      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:

      six months ended June 30, 2003, aggregated $2,503,072 and $16,720,305,

(a)  The Portfolio 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 the ratio of net investment income to
     average net assets from 4.53% to 4.49%. Ratios for the periods prior to
     January 1, 2001 have not been restated to reflect this change in
     presentation.

(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 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, 2003 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, 2003 was approximately 100%.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Global Fixed Income Portfolio was changed to Standish Mellon
      Global Fixed Income Portfolio. In addition, the name of the Standish,
      Ayer & Wood Master Portfolio was changed to Mellon Institutional Funds
      Master Portfolio. The name changes for the Portfolio and the Master
      Portfolio are effective July 1, 2003.

      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. REPURCHASE AGREEMENTS

      It is the policy of the Portfolio to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the
      Portfolio and the counterparty. Additionally, procedures have been
      established by the Portfolio to monitor on a daily basis, the market value
      and accrued interest of the repurchase agreement's underlying investments
      to ensure the existence of a proper level of collateral.

     C. 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.

     D. 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.

     E. 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.

     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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("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.

      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
      investments, for the six months ended June 30, 2003 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.

      The cost and unrealized appreciation (depreciation) in value of the
      investment securities owned at June 30, 2003, 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 Parts A and B of the Portfolio Trust's registration statement.

      The Portfolio trades 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

                                       22

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

      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 six months ended June 30,
      2003 is as follows:

     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.

     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, 2003, the Portfolio held the following financials futures
      contracts:

     INTEREST RATE SWAP CONTRACTS

      Interest rate swaps involve the exchange by the Portfolio with another
      party of their respective commitments to pay or receive interest, e.g., an
      exchange of floating rate payments for fixed rate payments with respect to
      a notional amount of principal. Credit and market risk exist with respect
      to these instruments. If forecasts of interest rates and other market
      factors are incorrect, investment performance will be diminished 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 into
      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,
      managing duration or protecting against an increase in the price of
      securities the Portfolio anticipates purchasing at a later date. Interest
      rate swaps are marked to market daily based upon quotations from market
      makers and the change, if any, is recorded as unrealized gain or loss.
      Payments made or received are included as part of interest income. Gains
      and losses are realized upon the expiration or closing of the swap
      contracts.

      The Portfolio entered into no such transactions during the six months
      ended June 30, 2003.

(6)  SECURITIES LENDING:

      The Portfolio may lend its securities, through its agent Investors Bank &
      Trust Co., to financial institutions which Standish Mellon 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

                                       25

      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.

      At June 30, 2003, the Portfolio loaned securities having a market value of
      $2,419,765. The Portfolio received cash collateral of $2,482,750 which is
      invested, together with collateral of other Mellon Institutional funds, in
      high-grade short-term investments.

(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.

      The Portfolio entered into no such transactions during the six months
      ended June 30, 2003.

                  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.

      The Fund currently offers two classes of shares: Institutional Class and
      Service Class. Expenses of the Fund are 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 votes separately as a class only with respect
      to its own distribution plan (Service Class only) or other matters that
      relate only to that class. Shares of each class would receive their
      pro-rata share of the net assets of the Fund (after satisfaction of any
      class-specific expenses) if the Fund were liquidated. In addition, the
      Trustees declare separate dividends on each class of shares.

      Shares of the Service Class may be purchased by entities ("Account
      Administrators") that provide omnibus accounting services for groups of
      individuals who beneficially own Service Class shares ("Omnibus
      Accounts"). Omnibus Accounts include pension and retirement plans (such as
      401(k) plans, 457 plans and 403(b) plans), and programs through which
      personal and or account maintenance services are provided to groups of
      individuals whether or not such individuals invest on a tax-deferred
      basis. Individual investors may only purchase Service Class shares through
      their Omnibus Account Administrators.

      The objective of the Fund is to maximize total return while realizing a
      market level of income consistent with preserving principal and liquidity
      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.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish International Fixed Income Fund was changed to Standish Mellon
      International Fixed Income Fund. In addition, the name of the Standish,
      Ayer & Wood Investment Trust was changed to Mellon Institutional Funds
      Investment Trust. The name changes for the Fund and the Trust are
      effective July 1, 2003.

      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.

                                       13

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

     B. REPURCHASE AGREEMENTS

      It is the policy of the Fund to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the Fund
      and the counterparty. Additionally, procedures have been established by
      the Fund to monitor on a daily basis, the market value and accrued
      interest of the repurchase agreement's underlying investments to ensure
      the existence of a proper level of collateral.

     C. SECURITIES TRANSACTIONS AND INCOME

      Securities transactions are recorded as of trade date. Interest income is
      determined on the basis of interest accrued, adjusted 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.

     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. DISTRIBUTIONS TO SHAREHOLDERS

      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 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,
      amortization and/or accretion of premiums and discounts on certain
      securities, capital loss carry forwards, losses deferred due to wash sales
      and excise tax regulations.

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

      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.

     G. ALLOCATION OF OPERATING ACTIVITY

      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. Investment
      income, common expenses and realized and unrealized gains and losses are
      allocated among the share classes of the Fund based on the relative net
      assets of each class. Transfer agent fees, which are directly attributable
      to a class of shares, are charged to that class' operations. Service fees,
      which are directly attributable to the Service Class shares, are charged
      to the Service Class operations.

     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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("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 six months ended June 30, 2003, so that the Service Class annual
      operating expenses do 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 six months ended June 30, 2003, Standish Mellon reimbursed the
      Service Class $6,569 for class specific operating expenses. This agreement
      is voluntary and temporary and may be discontinued or revised by Standish
      Mellon at any time.

      Effective January 28, 2003, the Institutional Class of the Fund began
      imposing 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. The fee does not apply to
      shares that were acquired through reinvestment of distributions. The
      redemption fee is applicable to shares of the Institutional Class
      purchased on or after January 28, 3003. For the period ended June 30,
      2003, the Fund received $142 in 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)  SERVICE FEE:

      Pursuant to a service plan, the Service Class pays a service fee at an
      aggregate annual rate of up to 0.25% of the class' average daily net
      assets. The service fee is payable for the benefit of participants in the
      omnibus accounts that are

(7)  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 trades 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.

      June 30, 2003 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.

      At June 30, 2003, the Fund held the following financials futures
      contracts:

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

     INTEREST RATE SWAP CONTRACTS

      Interest rate swaps 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. 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 Fund expects to enter into 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 swaps are
      marked to market daily based upon quotations from market makers and the
      change, if any, is recorded as unrealized gain or loss. Payments made or
      received are included as part of interest income. Gains and losses are
      realized upon the expiration or closing of the swap contracts.

      The Fund entered into no such transactions during the six months ended
      June 30, 2003.

(8)  SECURITIES LENDING:

      The Fund may lend its securities, through its agent Investors Bank & Trust
      Co., to financial institutions which Standish Mellon 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.

      At June 30, 2003, the Fund loaned securities having a market value of
      $859,805. The Fund received cash collateral of $885,100 which is invested,
      together with collateral of other Mellon Institutional funds, in
      high-grade short-term investments.

(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 $0.004, 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 periods prior to January 1, 2001 have not

                  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 Fund invests 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 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, 2003). 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 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 by the Portfolio investing, under normal
      circumstances, at least 80% of net assets in fixed income securities
      issued by U.S. and foreign governments and companies.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Fixed Income Fund was changed to Standish Mellon Fixed Income
      Fund. In addition, the name of the Standish, Ayer & Wood Investment Trust
      was changed to Mellon Institutional Funds Investment Trust. The name
      changes for the Fund and the Trust are effective July 1, 2003.

      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

                                       5


                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                       STANDISH MELLON FIXED INCOME FUND

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

      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.

     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:

      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 0.38% of the Fund's average daily net
      assets for the six months ended June 30, 2003. Pursuant to this agreement,
      for the six months ended June 30, 2003, Standish Mellon voluntarily
      reimbursed the Fund for $121,350 of its operating expenses. This agreement
      is voluntary and temporary and may be discontinued or revised by Standish
      Mellon at any time.

      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
      six months ended June 30, 2003, aggregated $10,021,412 and $181,939,231,
      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

                   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, 2003, 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, 2003 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.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Fixed Income Portfolio was changed to Standish Mellon Fixed
      Income Portfolio. In addition, the name of the Standish, Ayer & Wood
      Master Portfolio was changed to Mellon Institutional Funds Master
      Portfolio. The name changes for the Portfolio and the Portfolio Trust are
      effective July 1, 2003.

      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. REPURCHASE AGREEMENTS

      It is the policy of the Portfolio to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the
      Portfolio and the counterparty. Additionally, procedures have been
      established by the Portfolio to monitor on a daily basis, the market value
      and accrued interest of the repurchase agreement's underlying investments
      to ensure the existence of a proper level of collateral.

     C. 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.

     D. 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.

     E. 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.

     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. 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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("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. Standish Mellon voluntarily
      agreed to limit the Portfolio's total annual operating expenses (excluding
      brokerage commissions, taxes and extraordinary expenses) to 0.38% of the
      Portfolio's average daily net assets. Pursuant to this agreement, for the
      six months ended June 30, 2003, Standish Mellon voluntarily waived
      $124,405 of its investment advisory fee. This agreement is voluntary and
      temporary and may be discontinued or revised by Standish Mellon at any
      time.

      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.

      Purchases and proceeds from sales of investments, other than short-term
      obligations, for the six months ended June 30, 2003 were as follows:

(4)  FEDERAL TAXES:

(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 Parts A and B of the Portfolio Trust's registration statement.

      The Portfolio trades 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

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

      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 six months ended June 30,
      2003 is as follows:

      At June 30, 2003, the Portfolio held no written call option contracts.

     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, 2003, 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, 2003, 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.

(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.

      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, through its agent Investors Bank &
      Trust Co., to financial institutions which Standish Mellon 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

                                       26

      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.

      At June 30, 2003, the Portfolio loaned securities having a market value of
      $91,070,541. The Portfolio received cash collateral of $93,033,125 which
      is invested, together with collateral of other Mellon Institutional funds,
      in high-grade short-term investments.

*    For the periods indicated, the investment adviser voluntarily agreed not to

     the Fund for all or a portion of its operating expenses. If this voluntary
     action had not been taken, the investment income per share and the ratios
     would have been:

(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.
++   Not annualized
+++  Total return would have been lower in the absence of expense waivers.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
               STANDISH MELLON INTERNATIONAL FIXED INCOME FUND II

                   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 II (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
      by investing, under normal circumstances, at least 80% of net assets in
      fixed income securities, and at least 65% of net assets in non-U.S. dollar
      denominated fixed income securities of foreign government and companies
      located in various countries, including emerging markets.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish International Fixed Income Fund II was changed to Standish Mellon
      International Fixed Income Fund II. In addition, the name of the Standish,
      Ayer & Wood Investment Trust was changed to Mellon Institutional Funds
      Investment Trust. The name changes for the Fund and the Trust are
      effective July 1, 2003.

      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. REPURCHASE AGREEMENTS

      It is the policy of the Fund to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the Fund
      and the counterparty. Additionally, procedures have been established by
      the Fund to monitor on a daily basis, the market value and accrued
      interest of the repurchase agreement's underlying investments to ensure
      the existence of a proper level of collateral.

     C. 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

               STANDISH MELLON INTERNATIONAL FIXED INCOME FUND II

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

      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.

     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. 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.

     G. 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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("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
      0.55% of the Fund's average daily net assets for the six months ended
      June 30, 2003. Pursuant to this agreement, for the six months ended
      June 30, 2003, Standish Mellon voluntarily did not impose $45,227 of its
      investment advisory fee and reimbursed the Fund for $40,103 of its
      operating expenses. This agreement is voluntary and temporary and may be
      discontinued or revised by Standish Mellon at any time.

      Effective January 28, 2003, the Fund began imposing 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. The fee does not apply to shares that were acquired
      through reinvestment of distributions. The redemption fee is applicable to

      At June 30, 2003, two shareholders held of record approximately 73% and
      12% 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.

      The cost and unrealized appreciation (depreciation) in value of the
      investment securities at June 30, 2003 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 trades 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 six months ended June 30,
      2003 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.

      At June 30, 2003, the Fund held the following forward foreign currency
      exchange contracts.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
               STANDISH MELLON INTERNATIONAL FIXED INCOME FUND II

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

     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, 2003, the Fund held the following futures contracts:



                                                                        UNDERLYING FACE

                                                                                             =======


     INTEREST RATE SWAP CONTRACTS

      Interest rate swaps 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. 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 Fund expects to enter into 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 swaps are
      marked to market daily based upon quotations from market makers and the
      change, if any, is recorded as unrealized gain or loss. Payments made or
      received are included as part of interest income. Gains and losses are
      realized upon the expiration or closing of the swap contracts.

      The Fund entered into no such transactions during the six months ended
      June 30, 2003.

(7)  SECURITIES LENDING:

      The Fund may lend its securities, through its agent Investors Bank & Trust
      Co., to financial institutions which Standish Mellon 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

                                       18

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

      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.

      At June 30, 2003, the Fund loaned securities having a market value of
      $32,405. The Fund received cash collateral of $33,275 which is invested,
      together with collateral of other Mellon Institutional funds, in
      high-grade short-term investments.

(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
      transactions.

(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.
+    Total return would have been lower in the absense of expense waivers.
++   Computed on an annualized basis.
+++  Not annualized.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                  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 by investing, under normal circumstances, at least 80%
      of net assets in fixed income securities of U.S. companies and the U.S.
      government.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Short-Term Fixed Income Fund was changed to Standish Mellon
      Short-Term Fixed Income Fund. In addition, the name of the Standish,
      Ayer & Wood Investment Trust was changed to Mellon Institutional Funds
      Investment Trust. The name changes for the Fund and the Trust are
      effective July 1, 2003.

      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. REPURCHASE AGREEMENTS

      It is the policy of the Fund to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the Fund
      and the counterparty. Additionally, procedures have been established by
      the Fund to monitor on a daily basis, the market value and accrued
      interest of the repurchase agreement's underlying investments to ensure
      the existence of a proper level of collateral.

     C. 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.

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

     D. 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.

     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 expenses 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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("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 (excluding
      brokerage commissions, taxes and extraordinary expenses) to 0.30% of the
      Fund's average daily net assets for the six months ended June 30, 2003.
      Pursuant to this agreement, for the six months ended June 30, 2003,
      Standish Mellon voluntarily did not impose $32,715 of its investment
      advisory fee and reimbursed the Fund for $37,876 of its operating
      expenses. This agreement is voluntary and temporary and may be
      discontinued or revised by Standish Mellon at any time.

      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.

      At June 30, 2003, three shareholders held of record approximately 54%, 14%
      and 13% 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.

      The cost and unrealized appreciation (depreciation) in value of the
      investment securities owned at June 30, 2003, as computed on a federal

(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.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                  STANDISH MELLON SHORT-TERM FIXED INCOME FUND

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

      The Fund trades 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 six months ended
      June 30, 2003.

     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 six months ended
      June 30, 2003.

(7)  SECURITIES LENDING:

      The Fund may lend its securities, through its agent Investors Bank & Trust
      Co., to financial institutions which Standish Mellon deems to be
      creditworthy. The loans are collateralized at all times with cash or
      securities with a market value at

                                       10


                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST

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

      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.

      At June 30, 2003, the Fund loaned securities having a market value of
      $562,852. The Fund received cash collateral of $574,375 which is invested,
      together with collateral of other Mellon Institutional funds, in
      high-grade short-term investments.

(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, 2003, the Fund did not have any delayed delivery transactions.

     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 $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 invests 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 Trust 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, 2003). 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.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Short-Term Asset Reserve Fund was changed to Standish Mellon
      Short-Term Asset Reserve Fund. In addition, the name of the Standish,
      Ayer & Wood Investment Trust was changed to Mellon Institutional Funds
      Investment Trust. The name changes for the Fund and the Trust are
      effective July 1, 2003.

      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.

                                       5


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

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

      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.

(2)  INVESTMENT ADVISORY FEE:

      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 0.36% of the Fund's average daily net
      assets for the six months ended June 30, 2003. Pursuant to this agreement,
      for the six months ended June 30, 2003, Standish Mellon voluntarily
      reimbursed the Fund for $45,589 of its operating expenses. This agreement
      is voluntary and temporary and may be discontinued or revised by Standish
      Mellon at any time.

      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
      six months ended June 30, 2003, aggregated $102,013,486 and $60,549,536,
      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, 2003, two shareholders held of record approximately 38% and
      11% 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.

      See coresponding master portfolio for tax basis unrealized
      appreciation/(depreciation) information.

                   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, 2003 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, 2003 was approximately 100%.

      The objective of the Portfolio is to achieve a high level of current
      income consistent with preserving principal and liquidity 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.

      On June 21, 2003, by vote of the Board of Trustees, the name of the
      Standish Short-Term Asset Reserve Portfolio was changed to Standish Mellon
      Short-Term Asset Reserve Portfolio. In addition, the name of the Standish,
      Ayer & Wood Master Portfolio was changed to Mellon Institutional Funds
      Master Portfolio. The name changes for the Portfolio and the Master
      Portfolio are effective July 1, 2003.

      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. REPURCHASE AGREEMENTS

      It is the policy of the Portfolio to require the custodian bank to take
      possession of, to have legally segregated in the Federal Reserve Book
      Entry System, or to have segregated within the custodian bank's vault, all
      securities held as collateral in support of repurchase agreement
      investments. Collateral for certain tri-party repurchase agreements is
      held at the custodian in a segregated account for the benefit of the
      Portfolio and the counterparty. Additionally, procedures have been
      established by the Portfolio to monitor on a daily basis, the market value
      and accrued interest of the repurchase agreement's underlying investments
      to ensure the existence of a proper level of collateral.

     C. 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.

     D. 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.

     E. DEFERRED ORGANIZATIONAL EXPENSES

      Costs incurred by the Portfolio in connection with its organization and
      initial registration are being amortized on a straight-line basis through
      January 2003.

     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.

(2)  INVESTMENT ADVISORY FEE:

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("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. Standish Mellon voluntarily agreed
      to limit the Portfolio's total annual operating expenses (excluding
      brokerage commissions, taxes and extraordinary expenses) to 0.36% of the
      Portfolio's average daily net assets for the six months ended June 30,
      2003. Pursuant to this agreement, for the six months ended June 30, 2003,
      Standish Mellon voluntarily did not impose $5,942 of its investment
      advisory fees. This agreement is voluntary and temporary and may be
      discontinued or revised by Standish Mellon at any time.

      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.

(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.

      investment securities owned at June 30, 2003, 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 Parts A and B of the Portfolio Trust's registration statement.

      The Portfolio trades 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.

                                       18

               STANDISH MELLON SHORT-TERM ASSET RESERVE PORTFOLIO

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

      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 six months
      ended June 30, 2003.

     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, 2003, 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, 2003, the Portfolio held the following financials futures
      contracts:

      At June 30, 2003, the Portfolio had segregated sufficient cash and/or
      securities to cover margin requirements on open futures contracts.

                  MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
               STANDISH MELLON SHORT-TERM ASSET RESERVE PORTFOLIO

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

(6)  SECURITIES LENDING:

      The Portfolio may lend its securities, through its agent Investors Bank &
      Trust Co., to financial institutions which Standish Mellon 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.

      At June 30, 2003, the Portfolio loaned securities having a market value of
      $28,377,464. The Portfolio received cash collateral of $29,400,062 which
      is invested, together with collateral of other Mellon Institutional funds,
      in high-grade short-term investments.

(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.

      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, 2003, the Portfolio did not have any delayed delivery
      transactions.
