                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                THE BOSTON COMPANY INTERNATIONAL CORE EQUITY 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. The
     Boston Company International Core Equity 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 Boston
     Company International Core Equity Portfolio (the "Portfolio"), a subtrust
     of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"),
     which is organized as a New York trust, and has the same investment
     objective as the Fund. The Portfolio seeks to achieve its objective by
     investing, under normal circumstances, at least 80% of net assets in equity
     securities of companies located in the foreign countries represented in the
     MSCI Europe, Australia, Far East Index and Canada. The value of the Fund's
     investment in the Portfolio reflects the Fund's proportionate interest in
     the net assets of the Portfolio (approximately 98.9% at March 31, 2004).
     The performance of the Fund is directly affected by the performance of the
     Portfolio. The financial statements of the Portfolio are included elsewhere
     in this report and should be read in conjunction with the Fund's financial
     statements.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. INVESTMENT RISK

     The Fund's investment in the Portfolio involves certain additional risks
     due to the fact that the Portfolio may invest in foreign securities that
     were 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 have been 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.

     D. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on 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. 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, passive foreign
     investment companies (PFICs), post-October loss deferrals, wash sales and
     capital loss carryovers.


                                        6


                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                THE BOSTON COMPANY INTERNATIONAL CORE EQUITY FUND

                    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 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 AND OTHER TRANSACTIONS WITH AFFILIATES:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to for
     such services. See Note 2 of the Portfolio's Notes to Financial Statements
     which are included elsewhere in this report. The Boston Company Asset
     Management, LLC ("TBCAM") 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 1.25% of the
     Fund's average daily net assets for the for the period ended March 31,
     2004. Pursuant to this agreement, for this period ended March 31, 2004,
     TBCAM was not required to reimburse the Fund as the Fund operated below the
     agreed expense limit. This agreement is temporary and voluntary and may be
     discontinued or revised by TBCAM at any time.

     As of February 23, 2004, the Fund compensates Dreyfus Transfer, Inc., a
     wholly owned subsidiary of Dreyfus, an affiliate of TBCAM, under a transfer
     agency agreement for providing personnel and facilities to perform transfer
     agency services for the Fund. Pursuant to this agreement the Fund was
     charged $121 during the period ended March 31, 2004.
     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     90 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading. The fee does
     not apply to shares that were acquired through reinvestment of
     distributions. For the period ended March 31, 2004, the Fund received no
     redemption fees.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the 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)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     period ended March 31, 2004, aggregated $14,753,283 and $15,543,643.

(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:

                   MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
             THE BOSTON COMPANY INTERNATIONAL CORE EQUITY PORTFOLIO

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
     organized as a master trust fund under the laws of the State of New York on
     January 18, 1996 and is registered under the Investment Company Act of
     1940, as amended, as an open-end, management investment company. The Boston
     Company International Core Equity Portfolio (the "Portfolio"), a separate
     diversified investment series of the Portfolio Trust, commenced operations
     on January 28, 2003.

     The objective of the Portfolio is to achieve long-term growth of capital.
     The Portfolio seeks to achieve its objective by investing, under normal
     circumstances, at least 80% of net assets in equity securities of companies
     that are located in the foreign countries represented in the MSCI Europe,
     Australia, Far East Index and Canada.

     At March 31, 2004, there were two funds, The Boston Company International
     Core Equity Fund and Dreyfus Premier International Equity Fund invested in
     the Portfolio. The value of the funds' investment in the Portfolio reflects
     the funds' proportionate interests in the net assets of the Portfolio. At
     March 31, 2004, The Boston Company International Core Equity Fund and the
     Dreyfus Premier International Equity Fund held approximately 98.9% and 1.1%
     interests in the Portfolio, respectively.

     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, or the
     NASDAQ official close if applicable, in the principal market in which such
     securities are normally traded. Because foreign markets may be open at
     different times than the New York Stock Exchange, the value of the
     Portolio's shares may change on days when shareholders are not able to buy
     or sell them. Many securities markets and exchanges outside the U.S. close
     prior to the close of the New York Stock Exchange and therefore the closing
     prices for securities in such markets or on such exchanges may not fully
     reflect the events that occur after such close but before the close of the
     New York Stock Exchange.

     If market quotations are not readily available or do not accurately reflect
     fair value, or the value of a security has been materially affected by
     events occurring after the close of the exchange or market on which the
     security is principally traded (for example, a foreign exchange or market),
     the Portfolio may value its assets by a method the Trustees believe
     accurately reflects the fair value. The Trustees have adopted fair value
     pricing procedures, which, among other things, require the Portfolio to
     fair value such secutities if there has been a movement in the U.S. market
     that exceeds a specified threshold. Although the threshold may be revised
     from time to time and the number of days on which fair value prices will be
     used will depend on market activity, it is possible that fair value prices
     for foreign securities will be used by each fund to a significant extent.

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

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Interest income
     is determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method.
     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 Portfolio's books and the
     U.S. dollar equivalent amounts usually received or paid.

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

     C. INCOME TAXES

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

     D. FOREIGN CURRENCY TRANSACTIONS

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

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

     E. INVESTMENT RISK

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

     F. COMMITMENTS AND CONTINGENCIES

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

     G. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by The Boston Company Asset Management, LLC ("TBCAM") or its
     affiliates.

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

     The investment advisory fee paid to TBCAM for overall investment advisory,
     administrative services, and general office facilities, is paid monthly at
     the annual rate of 0.80% of the Portfolio's average daily net assets.

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

(5)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

     The Portfolio did not enter into option transactions during the period
     ended March 31, 2004.

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     At March 31, 2004, the Portfolio held the following forward foreign
     currency exchange contracts:

     FUTURES CONTRACTS

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

     At March, 31, 2004, the Portfolio held the following futures contracts:



                                                                                       UNDERLYING FACE           UNREALIZED

(6)  SECURITY LENDING:

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

     The Portfolio loaned securities during the period ended March 31, 2004
     resulting in security lending income. At March 31, 2004 the Portfolio had
     $21,098,659 worth of securities on loan.

(7)  LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
     Mellon Institutional Funds Investment Trust (the "Trust") are parties to a
     committed line of credit facility, which enables each portfolio/fund to
     borrow, in the aggregate, up to $35 million. Interest is charged to each
     participating portfolio/fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. In addition, a commitment fee,
     computed at an annual rate of 0.060 of 1% on the daily unused portion of
     the facility, is allocated ratably among the participating portfolios/funds
     at the end of each quarter. For the period ended March 31, 2004, the
     commitment fee was $1,277 for the Portfolio.

     During the period ended March 31, 2004, the Portfolio had no borrowings
     under the credit facility.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                     THE BOSTON COMPANY LARGE CAP CORE 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. The
     Boston Company Large Cap Core Fund (the "Fund") is a separate diversified
     investment series of the Trust.

     The objective of the Fund is to achieve long-term growth of capital. The
     Fund invests all of its investable assets in an interest of The Boston
     Company Large Cap Core Portfolio (the "Portfolio"), a subtrust of Mellon
     Institutional Funds Master Portfolio (the "Portfolio Trust"), which is
     organized as a New York trust, and which has the same investment objective
     as the Fund. The Portfolio seeks to achieve its objective by investing,
     under normal circumstances, at least 80% of net assets in equity securities
     in companies that appear to be undervalued relative to underlying business
     fundamentals. 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 March 31, 2004). The performance of the Fund is
     directly affected by the performance of the Portfolio. The financial
     statements of the Portfolio are included elsewhere in this report and
     should be read in conjunction with the Fund's financial statements.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on 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. 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 wash sales, post-October losses and realized and
     unrealized gains or losses on futures.

     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 may include temporary book and tax basis
     differences which will reverse in a subsequent period. Any taxable income
     or gain remaining at fiscal year end is distributed in the following year.

     D. EXPENSES

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

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

     E. COMMITMENT AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE AND TRANSACTIONS WITH AFFILIATES:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to TBCAM
     for such services. See Note 2 of the Portfolio's Notes to Financial
     Statements which are included elsewhere in this report. Effective November
     1, 2003, TBCAM 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 0.90% of the Fund's
     average daily net assets for the period ended March 31, 2004. Prior to that
     the voluntary expense limitation was 0.71% of the Funds average daily net
     assets. Pursuant to this agreement, for the period ended March 31, 2004,
     TBCAM voluntarily reimbursed the Fund for $6,986 of its operating expenses.
     This agreement is temporary and voluntary and may be discontinued or

                  THE BOSTON COMPANY LARGE CAP CORE PORTFOLIO

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

     At March 31, 2004, there was one fund, The Boston Company Large Cap Core
     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 March
     31, 2004 was approximately 100%.

     The objective of the Portfolio is long-term growth of capital. The
     Portfolio seeks to achieve its objective by investing, under normal
     circumstances, of at least 80% of net assets in equity and equity-related
     securities of companies which appear to be undervalued relative to current
     earnings growth.

     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, or the
     NASDAQ official close if applicable, in the principal market in which such
     securities are normally traded. Securities (including illiquid securities)
     for which quotations are not readily available are valued at their fair
     value as determined in good faith under consistently applied procedures
     under the general supervision of the Trustees.

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

     B. SECURITIES TRANSACTION AND INCOME

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

     C. INCOME TAXES

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

     D. COMMITMENTS AND CONTINGENCIES

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

     E. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by The Boston Company Asset Management, LLC ("TBCAM").

(2)  INVESTMENT ADVISORY FEE AND TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to TBCAM 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. Effective November 1, 2003, TBCAM
     voluntarily agreed to limit the Portfolio's total annual operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     0.90% of the Porfolio's average daily net assets for the period ended March
     31, 2004. Prior to November 1, 2003 the voluntary expense limitation was
     0.71% of the Portfolio's average daily net assets. Pursuant to this
     agreement, for the period ended March 31, 2004, TBCAM voluntarily waived
     $3,826 of its investment advisory fees. This agreement is voluntary and
     temporary and may be discontinued or revised by TBCAM at any time.

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio was charged $37,801 during the period ended
     March 31, 2004.

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

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the period ended March 31, 2004, were $18,046,118 and
     $28,365,639, respectively. For the period ended March 31, 2004, the
     Portfolio did not purchase or sell any long-term U.S. Government
     securities.

(4)  FEDERAL TAXES:

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2004, as computed on a federal
     income tax basis, were as follows:

     Aggregate Cost                                        $54,052,681
                                                           ===========

                                                           -----------

                                                           ===========

(5)  FINANCIAL INSTRUMENTS:

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

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Portfolio may use options to seek to hedge against
     risks of market exposure and changes in security prices and foreign
     currencies, as well as to seek to enhance returns. Writing puts and buying
     calls tend to increase the Portfolio's exposure to the underlying
     instrument. Buying puts and writing calls tend to decrease the Portfolio's

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

     exposure to the underlying instrument, or hedge other Portfolio
     investments. Options, both held and written by the Portfolio, are reflected
     in the accompanying Statement of Assets and Liabilities at market value.
     The underlying face amount at value of any open purchased options is shown
     in the Schedule of Investments. This amount reflects each contract's
     exposure to the underlying instrument at period end. Losses may arise from
     changes in the value of the underlying instruments if there is an illiquid
     secondary market for the contract or if the counterparty does not perform
     under the contract's terms.

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

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

     The Portfolio entered into no such transactions during the period ended
     March 31, 2004.

     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 March 31, 2004, the Portfolio held the following financial futures
     contracts:



                                                                        UNDERLYING FACE

(6)  LINE OF CREDIT:

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

     For the period ended March 31, 2004, the commitment fee was $1,070 for the
     Portfolio.

     During the period ended March 31, 2004, the Portfolio had no borrowings
     under the credit facility.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                 THE BOSTON COMPANY INTERNATIONAL SMALL CAP 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. The
     Boston Company International Small Cap 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 The
     Boston Company International Small Cap Portfolio (the Portfolio), a
     subtrust of Mellon Institutional Funds Master Portfolio (the Portfolio
     Trust), which is organized as a New York trust, and has the same investment
     objective as the Fund. The Portfolio seeks to achieve its objective by
     investing, under normal circumstances, at least 80% of net assets in equity
     securities in companies that are located in foreign countries represented
     in the Citigroup Extended Market Ex-U.S. (EMI-U.S.) Index. The Portfolio
     may invest up to 25% of its assets in emerging market countries. The value
     of the Fund's investment in the Portfolio reflects the Fund's proportionate
     interest in the net assets of the Portfolio (approximately 99% at March 31,
     2004). The performance of the Fund is directly affected by the performance
     of the Portfolio. The financial statements of the Portfolio are included
     elsewhere in this report and should be read in conjunction with the Fund's
     financial statements.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. 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 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. 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, passive foreign
     investment companies (PFICs) and capital loss carryovers.

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

     D. EXPENSES

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

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

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

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

     As of February 23, 2004, the Fund compensates Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of Dreyfus, an affiliate of TBCAM, under a transfer
     agency agreement for providing personnel and facilities to perform transfer
     agency services for the Fund. Pursuant to this agreement the Fund was
     charged $121 during the period ended March 31, 2004.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     90 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading. The fee does
     not apply to shares that were acquired through reinvestment of
     distributions. For the period ended March 31, 2004, the Fund received no
     redemption fees.

     No director, officer or employee of TBCAM 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 TBCAM or its affiliates an annual fee and a per
     meeting fee as well as reimbursement for travel and out of pocket expenses.
     In addition, the Trust pays the legal fees for the independent counsel of
     the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     period ended March 31, 2004, aggregated $23,646,331 and $1,552,204,
     respectively.

(4)  SHARES OF BENEFICIAL INTEREST:

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



                                                                           PERIOD ENDED

     At March 31, 2004, five shareholder of record held approximately 31%, 10%,
     9%, 7% and 6% of the total outstanding shares of the Fund. Investment
     activities of this shareholder could have a material impact on the Fund.

(5)  FEDERAL TAXES:

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

                   MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
              THE BOSTON COMPANY INTERNATIONAL SMALL CAP PORTFOLIO

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
     organized as a master trust fund under the laws of the State of New York on
     January 18, 1996 and is registered under the Investment Company Act of
     1940, as amended, as an open-end, management investment company. The Boston
     Company International Small Cap Portfolio (the "Portfolio"), a separate
     diversified investment series of the Portfolio Trust, commenced operations
     on January 28, 2003.

     The objective of the Portfolio is to achieve long-term growth of capital.
     The Portfolio seeks to achieve its objective by investing, under normal
     circumstances, at least 80% of net assets in equity securities of companies
     that are located in foreign countries represented in the Citigroup Extended
     Market Ex-U.S. (EMI-U.S.) Index. The Portfolio may invest up to 25% of its
     assets in emerging market countries.

     At March 31, 2004, there were two funds, The Boston Company International
     Small Cap Fund and Dreyfus Premier International Small Cap Fund invested in
     the Portfolio. The value of the funds' investment in the Portfolio reflects
     the funds' proportionate interests in the net assets of the Portfolio. At
     March 31, 2004, The Boston Company International Small Cap Fund and the
     Dreyfus Premier International Small Cap Fund held approximately 99% and 1%
     interests in the Portfolio, respectively.

     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, or the
     NASDAQ official close if applicable, in the principal market in which such
     securities are normally traded. Because foreign markets may be open at
     different times than the New York Stock Exchange, the value of the
     Portolio's shares may change on days when shareholders are not able to buy
     or sell them. Many securities markets and exchanges outside the U.S. close
     prior to the close of the New York Stock Exchange and therefore the closing
     prices for securities in such markets or on such exchanges may not fully
     reflect the events that occur after such close but before the close of the
     New York Stock Exchange.

     If market quotations are not readily available or do not accurately reflect
     fair value, or the value of a security has been materially affected by
     events occurring after the close of the exchange or market on which the
     security is principally traded (for example, a foreign exchange or market),
     the Portfolio may value its assets by a method the Trustees believe
     accurately reflects the fair value. The Trustees have adopted fair value
     pricing procedures, which, among other things, require the Portfolio to
     fair value such secutities if there has been a movement in the U.S. market
     that exceeds a specified threshold. Although the threshold may be revised
     from time to time and the number of days on which fair value prices will be
     used will depend on market activity, it is possible that fair value prices
     for foreign securities will be used by each fund to a significant extent.

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

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Interest income
     is determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method.
     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 Portfolio's books and the
     U.S. dollar equivalent amounts usually received or paid.

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

     C. INCOME TAXES

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

     D. FOREIGN CURRENCY TRANSACTIONS

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

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

     E. INVESTMENT RISK

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

     F. COMMITMENTS AND CONTINGENCIES

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

     G. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by the fund manager

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

     The investment advisory fee paid to The Boston Company Asset Management,
     LLC ("TBCAM") for overall investment advisory, administrative services, and
     general office facilities, is paid monthly at the annual rate of 1.00% of
     the Portfolio's average daily net assets.

     The Fund compensates Mellon Bank, N.A., under a custody, administration and
     accounting services agreement for providing custody, fund administration
     and fund accounting services for the fund. Pursuant to this agreement the
     Fund was charged $85,546 during the period ended March 31, 2004.

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

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the period ended March 31, 2004 were $52,835,465 and
     $35,279,651, respectively. For the period ended March 31, 2004, the
     Portfolio did not purchase or sell any long-term U.S. Government
     securities.

(4)  FEDERAL TAXES:

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2004, as computed on a federal
     income tax basis, were as follows:

     Aggregate Cost                                        $97,160,937
                                                           ===========
     Gross unrealized appreciation                          39,793,319
     Gross unrealized depreciation                            (489,804)
                                                           -----------
     Net unrealized appreciation                           $39,303,515
                                                           ===========

(5)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

     The Portfolio did not enter into option transactions during the period
     ended March 31, 2004.

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

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     At March 31, 2004, the Portfolio held the following forward foreign
     currency exchange contracts:



                                     LOCAL PRINCIPAL        CONTRACT              MARKET            AGGREGATE        UNREALIZED

     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

                   MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
              THE BOSTON COMPANY INTERNATIONAL SMALL CAP PORTFOLIO

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

(6)  SECURITY LENDING:

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

     The Portfolio loaned securities during the period ended March 31, 2004
     resulting in security lending income. At March 31, 2004, the Portfolio had
     $18,525,201 worth of securities on loan.

(7)  LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
     Mellon Institutional Funds Investment Trust (the "Trust") are parties to a
     committed line of credit facility, which enables each portfolio/fund to
     borrow, in the aggregate, up to $35 million. Interest is charged to each
     participating portfolio/fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. In addition, a commitment fee,
     computed at an annual rate of 0.060 of 1% on the daily unused portion of
     the facility, is allocated ratably among the participating portfolios/funds
     at the end of each quarter. For the period ended March 31, 2004, the
     commitment fee was $1,267 for the Portfolio.

     During the period ended March 31, 2004, the Portfolio had no borrowings
     under the credit facility.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                    THE BOSTON COMPANY SMALL CAP GROWTH 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. The
     Boston Company Small Cap Growth Fund (the "Fund") is a separate diversified
     investment series of the Trust.

     The objective of the Fund is to achieve long-term growth of capital. The
     Fund invests all of its investable assets in an interest in The Boston
     Company Small Cap Growth Portfolio (the "Portfolio"), a subtrust of Mellon
     Institutional Funds Master Portfolio (the "Portfolio Trust"), which is
     organized as a New York trust, and has the same investment objective as the
     Fund. The Portfolio seeks to achieve its investment objective by investing,
     under normal circumstances, at least 80% of its net assets in equity
     securities of small cap U.S. 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 March 31, 2004). The
     performance of the Fund is directly affected by the performance of the
     Portfolio. The financial statements of the Portfolio are included elsewhere
     in this report and should be read in conjunction with the Fund's financial
     statements.

     The 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 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 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. 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 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. 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 losses deferred due to wash sales, capital loss
     carryovers and realized and unrealized gains or losses on futures.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                    THE BOSTON COMPANY SMALL CAP GROWTH 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 undistributed
     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. The calculation of net investment income per share in the financial
     highlights table excludes these reclassifications.

     D. 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.

     E. COMMITMENTS AND CONTINGENCIES

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

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

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to The
     Boston Company Asset Management, LLC ("TBCAM") for such services. See Note
     2 of the Portfolio's Notes to Financial Statements which are included
     elsewhere in this report. TBCAM voluntarily agreed to limit the total
     operating expenses of the Portfolio's expenses (excluding brokerage
     commissions, taxes and extraordinary expenses) to 1.00% of the
     Institutional Class' average daily net assets for the period from October
     1, 2003 through October 31, 2003, and to 1.20% for the period from November
     1, 2003 through March 31, 2004. The total operating expenses of the Service
     Class and its pro rata share of the Portfolio's expenses (excluding
     brokerage commissions, taxes and extraordinary expenses) were limited 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 period ended March 31, 2004, TBCAM
     reimbursed the Institutional Class $23,049 and the Service Class $15,005
     for class-specific and Fund operating expenses. This agreement was
     voluntary and temporary and may be discontinued or revised by TBCAM at any
     time.

     As of February 23, 2004, the Fund compensates Dreyfus Transfer, Inc., a
     wholly owned subsidiary of Dreyfus, an affiliate of TBCAM, under a transfer
     agency agreement for providing personnel and facilities to perform transfer
     agency services for the Fund. Pursuant to this agreement the Fund was
     charged $242 during the period ended March 31, 2004.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     90 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading. The fee does
     not apply to shares that were acquired through reinvestment of
     distributions. For the period ended March 31, 2004, the Fund received $10
     in redemption fees.

     No director, officer or employee of TBCAM 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 TBCAM 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 shareholders in the Service Class and is intended
     to be compensation to Account Administrators for providing personal
     services and/or account maintenance services to participants in omnibus
     accounts that are the beneficial owners of Service Class shares.

(4)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     period ended March 31, 2004 aggregated $5,224,469 and $5,509,798
     respectively.

(5)  SHARES OF BENEFICIAL INTEREST:

     and 5% of the total outstanding shares of the Institutional Class and one

                  MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO

                  THE BOSTON COMPANY SMALL CAP GROWTH PORTFOLIO

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

     The objective of the Portfolio is to achieve long-term growth of capital.
     The Portfolio seeks to achieve its objective by investing, under normal
     circumstances, at least 80% of its net assets in equity securities of small
     cap U.S. companies.

     At March 31, 2004, there was one Fund, The Boston Company Small Cap Growth
     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 March
     31, 2004 was approximately 100%.

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

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price, or the
     NASDAQ official close if applicable, in the principal market in which such
     securities are normally traded. Securities (including illiquid securities)
     for which quotations are not readily available are valued at their fair
     value as determined in good faith under consistently applied procedures
     under the general supervision of the Trustees.

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. INCOME TAXES

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

     D. COMMITMENTS AND CONTINGENCIES

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

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

     E. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by The Boston Company Asset Management, LLC ("TBCAM") or its
     affiliates are described as "affiliated" in the Act.

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

     The investment advisory fee paid to TBCAM, a wholly-owned subsidiary of
     Mellon Financial Corporation, for overall investment advisory and
     administrative services is paid monthly at the annual rate of 0.80% of the
     Portfolio's average daily net assets. TBCAM voluntarily agreed to limit the
     total operating expenses of the Portfolio (excluding brokerage commissions,
     taxes and extraordinary expenses) to 1.00% of the Portfolio's average daily
     net assets for the period from October 1, 2003 through October 31, 2003,
     and to 1.20% for the period from November 1, 2003 through March 31, 2004.
     Pursuant to this agreement, for the period ended March 31, 2004, TBCAM did
     not impose $10,016 of its investment advisory fee. This agreement was
     voluntary and temporary and may be discontinued or revised by TBCAM at any
     time.

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio was charged $43,403 during the period ended
     March 31, 2004.

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

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the period ended March 31, 2004, were $27,770,048 and
     $27,885,914, respectively. For the period ended March 31, 2004, the
     Portfolio did not purchase or sell any long-term U.S. Government
     securities.

(4)  FEDERAL TAXES:

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2004, as computed on a federal
     income tax basis, were as follows:

     Aggregate Cost                                        $30,535,161
                                                           ===========
     Gross unrealized appreciation                           6,196,367
     Gross unrealized depreciation                            (422,243)
                                                           -----------
     Net unrealized appreciation                           $ 5,774,124
                                                           ===========

(5)  FINANCIAL INSTRUMENTS:

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

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


                                       19


                   MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
                  THE BOSTON COMPANY SMALL CAP GROWTH PORTFOLIO

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

     OPTIONS

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

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

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

     The Portfolio did not enter into option transactions during the Period
     ended March 31, 2004.

     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 March 31, 2004, the Portfolio held the following financial futures
     contracts:



                                                                               UNDERLYING FACE

(6)  SECURITY LENDING:

     The Portfolio may lend its securities to financial institutions which the
     Portfolio deems to be creditworthy. The loans are collateralized at all
     times with cash or securities with a market value at least equal to the
     market value of the securities on loan. The market value of securities
     loaned is determined daily and any additional required collateral is
     allocated to the Portfolio on the next business day. For the duration of a
     loan, the Portfolio receives the equivalent of the interest or dividends
     paid by the issuer on the securities loaned and also receives compensation
     from the investment of the collateral.

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

     As with other extensions of credit, the Portfolio bears the risk of delay
     in recovery or even loss of rights in its securities on loan should the
     borrower of the securities fail financially or default on its obligations
     to the Portfolio. In the event of borrower default, the Portfolio generally
     has the right to use the collateral to offset losses incurred. The
     Portfolio may incur a loss in the event it was delayed or prevented from
     exercising its rights to dispose of the collateral. The Portfolio also
     bears the risk in the event that the interest and/or dividends received on
     invested collateral is not sufficient to meet the Portfolio's obligations
     due on the loans.

     The Portfolio loaned securities during the period ended March 31, 2004
     resulting in security lending income. At March 31, 2004, the Portfolio had
     $979,164 worth of securities on loan.

(7)  LINE OF CREDIT:

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

     For the period ended March 31, 2004, the commitment fee was $499 for the
     Portfolio.

     During the period ended March 31, 2004, the Portfolio had borrowings under
     the credit facility. As a result of these borrowings the Portfolio incurred
     $30 of interest expense.


                                       21

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                    THE BOSTON COMPANY SMALL CAP VALUE 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. The
     Boston Company Small Cap Value 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 The
     Boston Company Small Cap Value Portfolio (the "Portfolio"), a subtrust of
     Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which
     is organized as a New York trust, and has the same investment objective as
     the Fund. The Portfolio seeks to achieve its objective by investing, under
     normal circumstances, at least 80% of net assets in equity securities of
     small cap U.S. 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 97% at March 31, 2004). The performance of the
     Fund is directly affected by the performance of the Portfolio. The
     financial statements of the Portfolio are included elsewhere in this report
     and should be read in conjunction with the Fund's financial statements.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. 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 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. 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 realized and unrealized gains or losses on futures
     contracts and wash sales.

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

     D. EXPENSES

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

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST

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

     E. COMMITMENTS AND CONTINGENCIES

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

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

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to The
     Boston Company Asset Management, LLC ("TBCAM") for such services. See Note
     2 of the Portfolio's Notes to Financial Statements which are included
     elsewhere in this report. TBCAM voluntarily agreed to limit the Fund's
     total operating expenses of the Fund and its pro rata share of the
     Portfolio expenses (excluding brokerage commissions, taxes and
     extraordinary expenses) to 1.25% of the Fund's average daily net assets.
     For the period ended March 31, 2004 the Fund operated below the agreed upon
     expense limit. This agreement was voluntary and temporary and may be
     discontinued or revised by TBCAM at any time.

     As of February 23, 2004, the Fund compensates Dreyfus Transfer, Inc., a
     wholly owned subsidiary of Dreyfus, an affiliate of TBCAM, under a transfer
     agency agreement for providing personnel and facilities to perform transfer
     agency services for the Fund. Pursuant to this agreement the Fund was
     charged $121 during the period ended March 31, 2004.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     90 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading. The fee does
     not apply to shares that were acquired through reinvestment of
     distributions. For the period ended March 31, 2004, the Fund received no
     redemption fees.

     No director, officer or employee of TBCAM 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 TBCAM or its affiliates an annual fee and a per
     meeting fee as well as reimbursement for travel and out of pocket expenses.
     In addition, the Trust pays the legal fees for the independent counsel of
     the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     period ended March 31, 2004 aggregated $8,101,910 and $5,492,888,
     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:



                                                                          SIX MONTHS ENDED

     At March 31, 2004, three shareholders of record held approximately 17%, 12%
     and 5% of the total outstanding shares of the Fund, respectively.
     Investment activities of these shareholders could have a material impact on
     the Fund.

                  MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
                  THE BOSTON COMPANY SMALL CAP VALUE PORTFOLIO

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
     organized as a master trust fund under the laws of the State of New York on
     January 18, 1996 and is registered under the Investment Company Act of
     1940, as amended, as an open-end, management investment company. The Boston
     Company Small Cap Value Portfolio (the "Portfolio"), a separate diversified
     investment series of the Portfolio Trust, commenced operations on January
     28, 2003.

     The objective of the Portfolio is to achieve long-term growth of capital.
     The Portfolio seeks to achieve its objective by investing, under normal
     circumstances, at least 80% of net assets in equity securities of small cap
     U.S. companies.

     At March 31, 2004, there were two funds, The Boston Company Small Cap Value
     Fund and Dreyfus Premier Small Cap Equity Fund invested in the Portfolio.
     The value of the funds' investment in the Portfolio reflects the funds'
     proportionate interests in the net assets of the Portfolio. At March 31,
     2004, The Boston Company Small Cap Value Fund and the Dreyfus Premier Small
     Cap Equity Fund held approximately 97% and 3% interests in the Portfolio,
     respectively.

     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, or the
     NASDAQ official close if applicable, in the principal market in which such
     securities are normally traded. Securities (including illiquid securities)
     for which quotations are not readily available are valued at their fair
     value as determined in good faith under consistently applied procedures
     under the general supervision of the Trustees.

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

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of interest accrued, adjusted for amortization of
     premium or discount on long-term debt securities when required for federal
     income tax purposes. Dividend income is recorded on the ex-dividend date.
     Realized gains and losses from securities sold are recorded on the
     identified cost basis. Dividends representing a return of capital are
     reflected as a reduction of cost, when the amount of return of capital is
     conclusively determined.

     C. INCOME TAXES

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

     D. COMMITMENTS AND CONTINGENCIES

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

     E. AFFILIATED ISSUERS

     Issuers in which the fund held investments in other investment companies
     advised by The Boston Company Asset Management, LLC ("TBCAM") or its
     affiliates.

(2)  INVESTMENT ADVISORY FEE:

     The investment advisory fee paid to TBCAM for overall investment advisory,
     administrative services, and general office facilities, is paid monthly at
     the annual rate of 0.80% of the Portfolio's average daily net assets.

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio was charged $37,566 during the period ended
     March 31, 2004.

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

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the period ended March 31, 2004 were $27,770,048 and
     $27,885,914, respectively. For the period ended March 31, 2004, the
     Portfolio did not purchase or sell any long-term U.S. Government
     securities.

(4)  FEDERAL TAXES:

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2004, as computed on a federal
     income tax basis, were as follows:

     Aggregate Cost                                        $44,974,005
                                                           ===========
     Gross unrealized appreciation                          10,658,694
     Gross unrealized depreciation                            (426,399)
                                                           -----------
     Net unrealized appreciation                           $10,232,295
                                                           ===========

(5)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

     Call and put options give the holder the right to purchase or sell a
     security or currency or enter into a swap arrangement on a future date at a
     specified price. The Portfolio may use options to seek to hedge against
     risks of market exposure and changes in security prices and foreign
     currencies, as well as to seek to enhance returns. Writing puts and buying
     calls tend to increase the Portfolio's exposure to the underlying
     instrument. Buying puts and writing calls tend to decrease the Portfolio's
     exposure to the underlying instrument, or hedge other Portfolio
     investments. Options, both held and written by the Portfolio, are reflected
     in the accompanying Statement of Assets and Liabilities at market value.
     The underlying face amount at value of any open purchased options is shown
     in the Schedule of Investments. This amount reflects each


                                       18


                   MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
                  THE BOSTON COMPANY SMALL CAP VALUE PORTFOLIO

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

     contract's exposure to the underlying instrument at period end. Losses may
     arise from changes in the value of the underlying instruments if there is
     an illiquid secondary market for the contract or if the counterparty does
     not perform under the contract's terms.

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

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

     The Portfolio did not enter into option transactions during the period
     ended March 31, 2004.

     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 March 31, 2004, the Portfolio held no outstanding financial futures
     contracts.

(6)  SECURITY LENDING:

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

     The Portfolio loaned securities during the period ended March 31, 2004
     resulting in security lending income. At March 31, 2004, the Portfolio had
     $3,120,266 worth of securities on loan.

(7)  LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
     Mellon Institutional Funds Investment Trust (the "Trust") are parties to a
     committed line of credit facility, which enables each portfolio/fund to
     borrow, in the aggregate, up to $35 million. Interest is charged to each
     participating portfolio/fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. In addition, a commitment fee,
     computed at an annual rate of 0.060 of 1% on the daily unused portion of
     the facility, is allocated ratably among the participating portfolios/funds
     at the end of each quarter. For the period ended March 31, 2004, the
     commitment fee was $767 for the Portfolio.

     During the period ended March 31, 2004, the Portfolio had borrowed under
     the credit facility and incurred $30 of interest expense.
