Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2004.

The past 12 months have been largely positive ones for the financial markets, as
the economic expansion continued. However, as the year progressed, estimates of
the recovery's strength have been reined in, to the benefit of fixed income and
the detriment of stocks.

The S&P 500 finished 2003 and entered 2004 with a sharp 100-point climb to its
peak in March, fueled to a large degree by above-trend GDP growth and driven by
a potent mix of tax cuts, monetary policy and government spending. But the
momentum stalled, as the market dealt with the prospect of inflation and a new
tightening cycle by the Federal Reserve, and the uncertainties of a tight
presidential campaign. Since March, the S&P 500 has been largely range-bound,
except for booming oil stocks. Economic indicators increasingly painted a
picture of a slowdown to more normal growth, and corporate profits appeared
strong, but less robust than anticipated.

In the bond market, 2003 ended with much speculation about when and how the Fed
would end one of the longest stretches of easy monetary policy on record, which
had driven rates to historical lows. In the fall of 2003, the prospect of
deflation was still a factor in the Fed's deliberations, and was its stated
rationale for maintaining an accommodative stance. Soon, however, the Fed began
to refer to a "measured pace" of tightening. The market reacted by switching
gears dramatically, sending the 10-year U.S. Treasury note from 3.7% on March 16
to 4.9% on June 14. Since then, as the economic outlook softened, with
relatively tame inflation, yields have settled back to about 4%, roughly the
same as a year ago.

Looking ahead, it's clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash, and are being deliberate in boosting employment and
spending on plant and equipment, as federal stimulus is waning. Nevertheless,
business activity has some significant momentum, which should carry over into
2005, with reasonably strong profit growth and modest inflation.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

September 2004

The Boston Company International Core Equity Fund (the "International Core
Equity Fund") return for the twelve months ended September 30, 2004 was 27.04%
versus 22.08% for its benchmark, the MSCI EAFE index. This was the second
consecutive year of better than 27% returns for the Fund. The Fund's 1 Year, 3
Year and 5 Year average annual total returns have exceeded the benchmark by
solid margins since the change of strategy to actively manage individual stock
holdings in 1996.

All but one EAFE market (Finland) posted double-digit annual returns, as
measured in US dollars. Norway proved to be the highest performing market with a
return of 65%. Finland's market lagged with a return of 5%. Energy stocks rose
the most with a 38.8% return, while Information Technology stocks rose the least
with a 4.5% return. Not surprisingly, Norway's market is heavily weighted toward
energy, and Finland's is dominated by technology, primarily Nokia. Energy stocks
were buoyed by oil prices that remained much higher than anticipated. Very
strong demand, especially from developing markets, and supply concerns due to
unrest in Iraq and elsewhere combined to keep oil prices high. Technology stocks
were depressed by very intense price competition, industry overcapacity,
reluctance of buyers to invest in new products, and valuation levels that still
appear to be too high relative to other sectors.

The International Core Equity Fund outperformed its index during the period,
largely due to our process of disciplined stock selection. Contribution to the
positive relative performance was broad based. The Fund outperformed the
benchmark in every region and in 17 of 21 countries. In addition the Fund
outperformed the benchmark in nine of 10 economic sectors. The Fund trailed its
benchmark only in the Health Care sector, and that by only a very modest amount

The portfolio continues to reflect our approach of investing in stocks of
companies that are attractively valued and exhibit improving business momentum.
The global economy is growing. Policy makers have begun the process of removing
the massive stimulus pumped into the system following the last recession and the
September 11 terrorist attacks. While policy has not yet moved into restrictive
territory, the combination of higher rates and higher oil prices may undermine
the strength of the economic expansion. Corporate profits are expected to grow,
but at a slower pace. It remains unclear whether investors will be encouraged by
the growth, or discouraged by the slowdown in the rate of growth. Overall,
valuation levels seem reasonable.

                THE BOSTON COMPANY INTERNATIONAL CORE EQUITY FUND

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, and (2) ongoing costs, including management
fees and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2004 to September 30, 2004).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000.00=8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expenses
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs. Therefore, the
second line of the table is useful in comparing ongoing costs and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

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

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 98.5% at September 30, 2004)
     . The performance of the Fund is directly affected by the performance of
     the Portfolio. The financial statements of the Portfolio are included
     elsewhere in this report and should be read in conjunction with the Fund's
     financial statements.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. 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 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.

     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 and redemptions in-kind. In 2004, the fund incurred
     a redemption in-kind which resulted in a realized gain of $4,426,312, which
     will be deferred indefinitely for tax purposes.

                                       9


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

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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 The
     Boston Company Asset Management, LLC ("TBCAM") a wholly owned subsidiary of
     Mellon Institutional Asset Management, for such services. See Note 2 of the
     Portfolio's Notes to Financial Statements which are included elsewhere in
     this report.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of TBCAM, to provide personnel and facilities to perform
     transfer agency and certain shareholder services for the Fund. For these
     services the Fund pays Dreyus Transfer, Inc. a fixed fee plus per account
     and transaction based fees, as well as, out-of-pocket expenses. Pursuant to
     this agreement the Fund was charged $3,500 during the year ended September
     30, 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 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.

     The following table sets forth all remuneration paid to the Trustees by the
     Fund for the fiscal year ended September 30, 2004. The fund also bears its
     pro rata share of the renumeration paid to the Trustees by the Portfolio.
     See Note 2 of the Portfolio's notes to financial statements which are
     included elsewhere in this report.

     year ended September 30, 2004 aggregated $48,077,039 and $23,245,417,
     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:



                                                                 For the                For the

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

     At September 30, 2004, one shareholder of record held approximately 34% of
     the total outstanding shares of the Fund. Investment activities of this
     shareholder could have a material impact on the Fund.

     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 year ended September 30, 2004, the Fund received no
     redemption fees.

(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.

     As of September 30, 2004, the components of distributable earnings on a tax
     basis were as follows:

         Undistributed ordinary income   $3,098,536

     Tax character of distributions paid during the fiscal year ended ended
     September 30, 2004 was as follows:

         Ordinary income                  1,441,503

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

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Investment Trust and the
Shareholders of The Boston Company International Core Equity Fund:

In our opinion, the accompanying statement of assets and liabilities, and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
The Boston Company International Core Equity Fund (the "Fund") at September 30,
2004, and the results of its operations, the changes in its net assets and the
financial highlights for each of the periods indicated, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of investment in the Portfolio at September
30, 2004 by correspondence with the custodian, provide a reasonable basis for
our opinion.

             THE BOSTON COMPANY INTERNATIONAL CORE EQUITY PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 September 30, 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 September 30, 2004, The Boston Company International Core
     Equity Fund and the Dreyfus Premier International Equity Fund held
     approximately 98.5% and 1.5% 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
- --------------------------------------------------------------------------------

     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. For

     owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM,

     the Portfolio. For these services the Portfolio pays Mellon Bank a fixed
     fee plus fees that are asset and transaction based, as well as,
     out-of-pocket expenses. Pursuant to this agreement the Portfolio was
     charged $150,179 during the year ended September 30, 2004.

     obligations, for the year ended September 30, 2004 were $97,530,191 and

     Portfolio did not purchase or sell any long-term U.S. Government
     securities.

(4)  FEDERAL TAXES:

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

     investment securities owned at September 30, 2004, as computed on a federal
     income tax basis, were as follows:

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


(5)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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


                                       26


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

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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 year 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 year ended
     September 30, 2004.

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     At September 30, 2004, the Portfolio held forward foreign currency exchange
     contracts. See Schedule of Investments for further detail.

     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 September 30, 2004, the Portfolio held futures contracts. See Schedule
     of Investments for further detail.

(6)  SECURITY LENDING:

     The Portfolio entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Portfolio's lending agent.
     Pursuant to this agreement Mellon Bank receives an agreed upon percentage
     of the net lending revenues. This compensation is a standard form of
     compensation received by securities lending agents with respect to
     non-affiliated entities.

     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 year ended September 30, 2004
     resulting in $64,099 worth of security lending income. At September 30,
     2004 the Portfolio had securities valued at $9,806,048 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 facility 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 year ended September 30, 2004, the
     facility fee was $1,805.

     During the year ended September 30, 2004, the Portfolio had no borrowings
     under the credit facility.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Master Portfolio and Investors of
The Boston Company International Core Equity Portfolio:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of The Boston Company International
Core Equity Portfolio (the "Portfolio") at September 30, 2004, and the results
of its operations, the changes in its net assets, and the financial highlights
for each of the periods indicated, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Portfolio's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at September 30, 2004 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2004.

The past 12 months have been largely positive ones for the financial markets, as
the economic expansion continued. However, as the year progressed, estimates of
the recovery's strength have been reined in, to the benefit of fixed income and
the detriment of stocks.

The S&P 500 finished 2003 and entered 2004 with a sharp 100-point climb to its
peak in March, fueled to a large degree by above-trend GDP growth and driven by
a potent mix of tax cuts, monetary policy and government spending. But the
momentum stalled, as the market dealt with the prospect of inflation and a new
tightening cycle by the Federal Reserve, and the uncertainties of a tight
presidential campaign. Since March, the S&P 500 has been largely range-bound,
except for booming oil stocks. Economic indicators increasingly painted a
picture of a slowdown to more normal growth, and corporate profits appeared
strong, but less robust than anticipated.

In the bond market, 2003 ended with much speculation about when and how the Fed
would end one of the longest stretches of easy monetary policy on record, which
had driven rates to historical lows. In the fall of 2003, the prospect of
deflation was still a factor in the Fed's deliberations, and was its stated
rationale for maintaining an accommodative stance. Soon, however, the Fed began
to refer to a "measured pace" of tightening. The market reacted by switching
gears dramatically, sending the 10-year U.S. Treasury note from 3.7% on March 16
to 4.9% on June 14. Since then, as the economic outlook softened, with
relatively tame inflation, yields have settled back to about 4%, roughly the
same as a year ago.

Looking ahead, it's clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash, and are being deliberate in boosting employment and
spending on plant and equipment, as federal stimulus is waning. Nevertheless,
business activity has some significant momentum, which should carry over into
2005, with reasonably strong profit growth and modest inflation.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

September 2004

The level of uncertainty in the equity markets has diverted investor attention
from investment fundamentals (e.g., earnings and earnings growth), to investment
behavior that is more emotionally driven. The current unsettled climate is
fostered by terrorist threats, the election puzzle, oil price uncertainty,
inflation fears and interest rate concerns. The economy continues to perform
relatively well and concerns about slowing economic growth and the resultant
slowing corporate profit growth seem to be somewhat overblown.

For the twelve months ended September 30, 2004 The Boston Company Small
Capitalization Equity Fund had a total return of 18.78%. This was well ahead of
the Russell 2000 Growth Index at 11.92% for the period. The Fund has had strong
relative performance in recent months as our holdings have been somewhat more
risk averse but, at the same time, it has participated fully in the recent
positive move. Within the markets, smaller stocks again performed better than
large stocks (the Russell 2000 was up 18.77% while the S&P 500 was up 13.87%),
and value has outpaced growth, especially in smaller stocks where the Russell
2000 Value Index was up more than twice that of the Russell 2000 Growth index.

Our risk averse approach continues to be a rewarding strategy in this very
volatile market environment. We are finding many companies we believe are truly
undervalued, not just cheap for an obvious reason. These potentially rewarding
opportunities seem to be a by-product of the prevailing market caution,
bordering on pessimism.

The US economy slowed a bit in the summer as higher energy prices and interest
rates, along with the uncertainty surrounding the election and its potential
market impact, reduced consumer and investor confidence and put a modest damper
on the stock market. We continue to view the economic landscape positively and
expect corporate capital spending to remain relatively strong.

Our best performing sectors relative to the index have been health care,
industrials and consumer discretionary. We expect strong earnings in these
sectors and continue to emphasize them in our portfolio allocation decisions.

Our energy holdings have been reduced at the margin as these stocks have done
well. We continue carry a market weight in this sector because of our long-term
positive outlook for energy prices. Our emphasis here continues to be on energy
services and exploration companies.


                                       2


We continue to deemphasize financials as most of these stocks are fully valued
in our view. Business momentum is neutral at best and rising interest rates will
further narrow spreads and put more pressure on earnings in coming quarters.
Stocks in the industrials sector are attractive because of the positive outlook
for corporate capital spending. We look for several more quarters of relatively
strong earnings from this group and remain significantly overweight here.

Our general outlook remains positive. We continue to find many companies in our
research universe we believe are undervalued with strong fundamentals and good
earnings prospects. With a good chance for continued economic growth and modest
inflation, capital spending should be robust for several quarters. The major
concerns were highlighted earlier but we believe our fundamental approach,
emphasizing strong business momentum and undervaluation, will yield good returns
even in this more volatile equity environment.

AVERAGE ANNUAL TOTAL RETURNS REFLECT THE CHANGE IN THE VALUE OF AN INVESTMENT,
ASSUMING REINVESTMENT OF THE FUND'S DIVIDEND INCOME AND CAPITAL GAINS. THE
$100,000 LINE GRAPH AND THE FUND'S RETURNS DO NOT REFLECT THE DEDUCTION OF TAXES
THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND
SHARES. DURING PERIODS OF REIMBURSEMENT BY THE FUND'S INVESTMENT ADVISER (IF
APPLICABLE), THE FUND'S TOTAL RETURN WILL BE GREATER THAN IT WOULD BE HAD THE
REIMBURSEMENT NOT OCCURRED. PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE
PERFORMANCE.

               THE BOSTON COMPANY SMALL CAPITALIZATION EQUITY FUND

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, and (2) ongoing costs, including management
fees and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2004 to September 30, 2004).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000.00=8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expenses
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs. Therefore, the
second line of the table is useful in comparing ongoing costs and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
               THE BOSTON COMPANY SMALL CAPITALIZATION EQUITY FUND

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 Capitalization Equity 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 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 with total market capitalizations equal to or less than 75%
     of the average total market capitalization of the largest companies
     included in the Russell 2000 Growth Index measured at the end of each of
     the previous twelve months.

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

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price, 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 Fund are valued at amortized cost, which approximates
     market value. If the Fund acquires a short-term instrument with more than
     sixty days remaining to its maturity, it is valued at current market value
     until the sixtieth day prior to maturity and will then be valued at
     amortized value based upon the value on such date unless the Trustees
     determine during such sixty-day period that amortized value does not
     represent fair value.

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. DISTRIBUTIONS TO SHAREHOLDERS

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

     D. EXPENSES

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

     E. COMMITMENTS AND CONTINGENCIES

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

     F. 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 0.60% of the Fund's average daily net assets. Effective
     November 30, 2003, TBCAM voluntarily agreed to limit total Fund operating
     expenses (excluding brokerage commissions, taxes and extraordinary
     expenses) to 1.00% of the Fund's average daily net assets for the year
     ended September 30, 2004. Prior to that date the voluntary rate was 0.74%.
     Pursuant to this agreement, for the year ended September 30, 2004, TBCAM
     collectively and voluntarily waived a portion of its investment advisory
     fee in the amount of $74,380. This agreement is voluntary and temporary and
     may be discontinued or revised by TBCAM at any time.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of TBCAM, to provide personnel and facilities to perform
     transfer agency and certain shareholder services for the Fund. For these
     services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account
     and transaction based fees, as well as, out-of-pocket expenses. Pursuant to
     this agreement the Fund was charged $3,500 during the year ended September
     30, 2004.

     The Fund has contracted Mellon Bank, N.A. ("Mellon Bank"), a wholly owned
     subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to
     provide custody, fund administration and fund accounting services for the
     Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset
     and transaction based fees, as well as, out-of-pocket expenses. Pursuant to
     this agreement the Fund was charged $67,883 during the year ended September
     30, 2004.

     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,

(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:



                                                                              For the               For the

                                                                         ------------------    ------------------
                                                                                                 
     Shares sold                                                               26,941                  23,955
     Shares issued to shareholders in payment of distributions declared           --                      130
       Shares redeemed                                                       (624,714)               (374,824)
                                                                             --------                --------
       Net increase (decrease)                                               (597,773)               (350,739)
                                                                             ========                ========


     At September 30, 2004, two shareholders of record held approximately 39%
     and 37% of the total outstanding shares of the Fund. Investment activity of
     these shareholders could have a material impact on the Fund.

     A significant portion of the Fund's shares represent investments by
     fiduciary accounts over which Standish Mellon and its affiliates have
     either sole or joint investment discretion.

     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 year ended September 30, 2004, the Fund received no
     redemption fees.

(5)  FEDERAL TAXES:

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

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2004, was as follows:


                                                  
     Unrealized appreciation                         $ 2,704,372
     Unrealized depreciation                            (578,423)
                                                     ----------
     Net unrealized appreciation/depreciation          2,125,949
     Undistributed ordinary income                          (383)
     Capital loss carry-forward                       (5,455,967)
                                                     ----------
     Total distributable earnings                    $(3,330,401)
                                                     ===========
     Cost for federal income tax purposes            $18,505,660


     At September 30, 2004, the Fund, for federal income tax purposes, has
     capital loss carryovers which will reduce the Fund's taxable income arising
     from net realized gain on investments, if any, to the extent permitted by
     the Internal Revenue Code and thus will reduce the amount of distributions
     to shareholders which would otherwise be necessary to relieve the Fund of
     any liability for federal income tax. Such capital loss carryovers are as
     follows:



              Capital Loss
               Carry Over                     Expiration Date
              -------------                   ---------------

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(6)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

     The Fund did not enter into option transactions during the year ended
     September 30, 2004.

     FUTURES CONTRACTS

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

     At September 30, 2004, the Fund held futures contracts. See Schedule of
     Investments for further details.

(7)  SECURITY LENDING:

     The Fund entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement the Mellon Bank receives an agreed upon
     percentage of the net lending revenues. This compensation is a standard
     form of compensation received by securities lending agents with respect to
     non-affiliated entities.

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

     The Fund loaned securities during the year ended September 30, 2004
     resulting in security lending income of $2,130. At September 30, 2004, the
     Fund had $1,372,944 worth of securities on loan.

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

(8)  LINE OF CREDIT:

     The Fund, and other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio Trust (the "Portfolio 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 facility fee, computed at an annual rate of .060 of 1% comitted amount,
     is allocated ratably among the participating portfolios/funds at the end of
     each quarter. For the year ended September 30, 2004, the facility fee was
     $490 for the Fund.

     During the year ended September 30, 2004, the Fund borrowed under the
     credit facility, and incurred $149 of interest expense.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Investment Trust and the
Shareholders of The Boston Company Small Capitalization Equity Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of The Boston Company Small
Capitalization Equity Fund (the "Fund") at September 30, 2004 and the results of
its operations, the changes in its net assets, and financial highlights for each
of the periods indicated, in conformity with accounting principles generally
accepted in the United States of America. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2004 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2004.

The past 12 months have been largely positive ones for the financial markets, as
the economic expansion continued. However, as the year progressed, estimates of
the recovery's strength have been reined in, to the benefit of fixed income and
the detriment of stocks.

The S&P 500 finished 2003 and entered 2004 with a sharp 100-point climb to its
peak in March, fueled to a large degree by above-trend GDP growth and driven by
a potent mix of tax cuts, monetary policy and government spending. But the
momentum stalled, as the market dealt with the prospect of inflation and a new
tightening cycle by the Federal Reserve, and the uncertainties of a tight
presidential campaign. Since March, the S&P 500 has been largely range-bound,
except for booming oil stocks. Economic indicators increasingly painted a
picture of a slowdown to more normal growth, and corporate profits appeared
strong, but less robust than anticipated.

In the bond market, 2003 ended with much speculation about when and how the Fed
would end one of the longest stretches of easy monetary policy on record, which
had driven rates to historical lows. In the fall of 2003, the prospect of
deflation was still a factor in the Fed's deliberations, and was its stated
rationale for maintaining an accommodative stance. Soon, however, the Fed began
to refer to a "measured pace" of tightening. The market reacted by switching
gears dramatically, sending the 10-year U.S. Treasury note from 3.7% on March 16
to 4.9% on June 14. Since then, as the economic outlook softened, with
relatively tame inflation, yields have settled back to about 4%, roughly the
same as a year ago.

Looking ahead, it's clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash, and are being deliberate in boosting employment and
spending on plant and equipment, as federal stimulus is waning. Nevertheless,
business activity has some significant momentum, which should carry over into
2005, with reasonably strong profit growth and modest inflation.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

September 2004

Investor focus has clearly shifted to the prevailing economic conditions over
the past year. Nudged along by steadily escalating oil prices and a close US
presidential race, a conservatism has emerged that has manifest itself in
weakening consumption, rising interest rates and corporate America's reluctance
to be excessively leveraged. Equity markets have languished as year-over-year
trading volumes have declined over 10%, and the Lehman Brothers Aggregate bond
index has more than doubled the return of the S&P 500 thus far in 2004.

For the 12 months ended September 30, 2004, The Boston Company Large Cap Core
Fund (formerly known as Standish Select Value Fund) had a total return of
13.23%. This put the Large Cap Core Fund slightly behind both the S&P 500 at
13.87% and the Russell 1000 Value Index, which returned 20.5%. The bulk of this
annual return is imbedded in the fourth quarter of 2003, as the broad market
rose only 1.5% through the first nine months of 2004.

Within the markets, results have been a mixed bag as well, with return
leadership still centered in mid and smaller capitalization ranges (below $10b),
while value has outperformed growth. From an absolute return perspective, energy
has been the best performing sector, and from a contribution to portfolio return
standpoint, it was the consumer staples sector.

Over the course of the past year the US markets have transitioned from a drastic
rebound to a more cautious advance, as the memories of the recent downturn are
still fresh in investors' minds. Interest rates bottomed out at 40-year lows,
global tension escalated in the Middle East, and oil prices soared beyond
$50/barrel. GDP has slowed its hasty rate of growth in 2003 to a more moderate
level. Increasing corporate expenditures, sinking jobless claims, and improving
fundamentals underpinned an increasingly cautious, albeit sustainable, advance
by US equities.

Regardless of the direction of the economy or the markets, the disciplined
investment approach used to manage the Large Cap Core Fund does not vary. Our
unwavering focus is on finding undervalued companies with improving business
momentum. The process begins with a computerized ranking of approximately 1000
large and liquid stocks. The computer modeling identifies those companies that
have the most attractive combination of low valuations and business strength.
Using this list of ranked candidates the analysts conduct further research to
identify those companies in the best position to maintain their business
momentum. The process ensures that the Large Cap Core Fund's holdings have an
attractive combination of better than average business strength and better than
average valuations. The strategy does not guarantee superior performance, but we
believe that over time it will prove to be successful.


                                       2


Although less robust than 2003, we expect the economy to continue to grow at a
more modest 3-4% annual rate as measured by GDP. Stock valuations have tightened
up in various segments of the equity markets, highlighting our fundamental
research and stock selection. Our portfolio team is focusing on the most
severely discounted stocks across all sectors. On a broader level there has been
a distinct shift away from a consumer driven economic expansion as the credit
tightening cycle is underway and energy prices have commanded a greater portion
of household income. Outlooks have admittedly shifted to 2005 and the
expectations that equity markets will rise moderately in an earnings driven
environment.

Thank you for your continued support.

AVERAGE ANNUAL TOTAL RETURNS REFLECT THE CHANGE IN THE VALUE OF AN INVESTMENT,
ASSUMING REINVESTMENT OF THE FUND'S DIVIDEND INCOME AND CAPITAL GAINS. THE
$100,000 LINE GRAPH AND THE FUND'S RETURNS DO NOT REFLECT THE DEDUCTION OF TAXES
THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND
SHARES. DURING PERIODS OF REIMBURSEMENT BY THE FUND'S INVESTMENT ADVISER (IF
APPLICABLE), THE FUND'S TOTAL RETURN WILL BE GREATER THAN IT WOULD BE HAD THE
REIMBURSEMENT NOT OCCURRED. PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE
PERFORMANCE.

                     THE BOSTON COMPANY LARGE CAP CORE FUND

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, and (2) ongoing costs, including management
fees and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2004 to September 30, 2004).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000.00=8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expenses
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs. Therefore, the
second line of the table is useful in comparing ongoing costs and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

+    EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIO OF 0.83%,

     COMBINED EXPENSES OF THE FUND AND THE MASTER PORTFOLIO IN WHICH IT INVESTS
     ALL ITS ASSETS.

(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. As of
     September 30, 2004 the Fund owned approximately 100% of the Portfolio's net
     assets. 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 based on the net
     asset value of the Portfolio. 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

     Investment 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
- --------------------------------------------------------------------------------

     E. COMMITMENT AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to The
     Boston Company Asset Management, LLC ("TBCAM") a wholly-owned subsidiary of
     Mellon Financial Corporation, for such services. See Note 2 of the
     Portfolio's Notes to Financial Statements which are included elsewhere in
     this report. 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 year
     ended September 30, 2004. Prior to that date the voluntary expense
     limitation rate was 0.71%. Pursuant to this agreement, for the year ended
     September 30, 2004, TBCAM voluntarily reimbursed the Fund for $7,419 of its
     operating expenses. This agreement is temporary and voluntary and may be
     discontinued or revised by TBCAM at any time.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of TBCAM, to provide personnel and facilities to perform
     transfer agency and certain shareholder services for the Fund. For these
     services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account
     and transaction based fees, as well as, out-of-pocket expenses. Pursuant to
     this agreement the Fund was charged $3,500 during the year ended September
     30, 2004.

     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.

     The following table sets forth all remuneration paid to the Trustees by the
     Fund for the fiscal year ended September 30, 2004. The fund also bears its
     pro rata share of the renumeration paid to the Trustees by the Portfolio.
     See Note 2 of the Portfolio's notes to financial statements which are
     included elsewhere in this report.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended aggregated $6,813,122 and $22,706,053, respectively. The Fund
     receives a proportionate share of the Portfolio's income, expenses, and
     realized and unrealized gains and losses based on applicable tax allocation
     rules. Book/tax differences arise when changes in proportionate interest
     for funds investing in the Portfolio occur. At September 30, 2004,
     unrealized appreciation (depreciation) on the Portfolio was allocated in
     the amount of $4,130,402 to the Fund and $1,219,888 to other entities
     previously invested in the Portfolio but since ceased operations.

(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:



                                                             For the                For the

     At September 30, 2004, two shareholders of record held approximately 12%
     and 11% of the total outstanding shares of the Fund, respectively.
     Investment activities of these shareholders could have a material impact on
     the Fund.

(5)  FEDERAL TAXES:

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

     As of September 30, 2004, the components of distributable earnings on a tax
     basis were as follows:

     Undistributed ordinary income          $   136,255

     Capital loss carry-forward              (1,315,495)

     At September 30, 2004, the Fund, for federal income tax purposes, has
     capital loss carryovers which will reduce the Fund's taxable income arising
     from net realized gain on investments, if any, to the extent permitted by
     the Internal Revenue Code and thus will reduce the amount of distributions
     to shareholders which would otherwise be necessary to relieve the Fund of
     any liability for federal income tax. Such capital loss carryovers are as
     follows:



                   Capital Loss
                    Carry Over                        Expiration Date
                  -------------                       ---------------
                                                      
                   $1,315,495                            9/30/2011


     Tax character of distributions paid during the fiscal year ended September
     30, 2004, was as follows:

        Distributions paid from:

        Ordinary income                           $568,427

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

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Investment Trust and the
Shareholders of The Boston Company Large Cap Core Fund:

In our opinion, the accompanying statement of assets and liabilities, and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
The Boston Company Large Cap Core Fund (the "Fund") at September 30, 2004 and
the results of its operations, the changes in its net assets, and the financial
highlights for each of the periods indicated, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of investment in the Portfolio at September
30, 2004 by correspondence with the custodian, provide a reasonable basis for
our opinion.

                   MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
                   THE BOSTON COMPANY LARGE CAP CORE PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 September 30, 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
     September 30, 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, 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. Dividends representing a return of capital are
     reflected as a reduction of cost.

     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.

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(2) INVESTMENT ADVISORY FEE:

     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. For the year ended September 30,
     2004, the Portfolio paid $298,188 in investment advisory fees to TBCAM.

     The Portfolio has contracted Mellon Bank, N.A. ("Mellon Bank"), a wholly
     owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM,
     to provide custody, fund administration and fund accounting services for
     the Portfolio. For these services the Portfolio pays Mellon Bank a fixed
     fee plus fees that are asset and transaction based, as well as,
     out-of-pocket expenses. Pursuant to this agreement the Portfolio was
     charged $75,579 during the year ended September 30, 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.

     The following table sets forth all remuneration paid to the Trustees by the
     Portfolio for the Portfolio's fiscal year ended September 30, 2004:

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended September 30, 2004, were $38,837,349 and
     $53,126,917, respectively. For the year ended September 30, 2004, the
     Portfolio did not purchase or sell any long-term U.S. Government
     securities.

(4)  FEDERAL TAXES:

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

     Aggregate Cost                                 $ 50,295,661
                                                    ============
     Gross unrealized appreciation                  $  6,544,162
     Gross unrealized depreciation                    (1,370,931)
                                                    ------------
     Net unrealized appreciation                    $  5,173,231
                                                    ============

(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:


                                       24


                   MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

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

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

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

     The Portfolio entered into no such transactions during the year ended
     September 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 September 30, 2004, the Portfolio held futures contracts. See Schedule
     of Investments for further detail.

(6)  LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust, as well as 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 facility fee, computed at an annual rate of 0.060 of 1% on the committed
     amount, is allocated ratably among the participating portfolios/funds at
     the end of each quarter. For the year ended September 30, 2004, the
     facility fee was $1,368 for the Portfolio.

     During the September 30, 2004, the Portfolio had borrowed under the credit
     facility incurring $34 of interest expense.

To the Trustees of Mellon Institutional Funds Master Portfolio and Investors of
The Boston Company Large Cap Core Portfolio:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of The Boston Company Large Cap Core
Portfolio (the "Portfolio") at September 30, 2004, and the results of its
operations, the changes in its net assets and the financial highlights for each
of the periods indicated, in conformity with accounting principles generally
accepted in the United States of America. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Portfolio's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2004 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2004.

The past 12 months have been largely positive ones for the financial markets, as
the economic expansion continued. However, as the year progressed, estimates of
the recovery's strength have been reined in, to the benefit of fixed income and
the detriment of stocks.

The S&P 500 finished 2003 and entered 2004 with a sharp 100-point climb to its
peak in March, fueled to a large degree by above-trend GDP growth and driven by
a potent mix of tax cuts, monetary policy and government spending. But the
momentum stalled, as the market dealt with the prospect of inflation and a new
tightening cycle by the Federal Reserve, and the uncertainties of a tight
presidential campaign. Since March, the S&P 500 has been largely range-bound,
except for booming oil stocks. Economic indicators increasingly painted a
picture of a slowdown to more normal growth, and corporate profits appeared
strong, but less robust than anticipated.

In the bond market, 2003 ended with much speculation about when and how the Fed
would end one of the longest stretches of easy monetary policy on record, which
had driven rates to historical lows. In the fall of 2003, the prospect of
deflation was still a factor in the Fed's deliberations, and was its stated
rationale for maintaining an accommodative stance. Soon, however, the Fed began
to refer to a "measured pace" of tightening. The market reacted by switching
gears dramatically, sending the 10-year U.S. Treasury note from 3.7% on March 16
to 4.9% on June 14. Since then, as the economic outlook softened, with
relatively tame inflation, yields have settled back to about 4%, roughly the
same as a year ago.

Looking ahead, it's clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash, and are being deliberate in boosting employment and
spending on plant and equipment, as federal stimulus is waning. Nevertheless,
business activity has some significant momentum, which should carry over into
2005, with reasonably strong profit growth and modest inflation.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

September 2004

Coupon income once again pushed municipal bond investment returns into positive
territory, more than offsetting the negative price impact of a modest increase
in interest rates. For the year ended September 30, 2004, the Standish Mellon
Massachusetts Intermediate Tax Exempt Bond Fund produced a total return after
expenses of 2.64%. This result trailed the benchmark performance index (Lehman
Muni 3,5,7 and 10 Year Index) return of 2.87%. Please note that the
Massachusetts Fund invests only in bonds the interest of which is exempt from
Massachusetts and federal income taxes, while the benchmark index is national in
scope.

Throughout the past year, bond market participants focused on how quickly the
Federal Reserve would hike short-term interest rates, and by how much. A steady
stream of strong employment and consumption data in early 2004 convinced
investors that the Fed would need to act aggressively to choke off any nascent
inflation. Consequently, all rates were pushed up in anticipation of the
pressures of a possibly overheating economy. The spike in yields was temporary,
and quickly reversed course as jobs and spending numbers weakened through the
summer months. By the end of the period, the Fed had abandoned its accommodative
policy, raising short rates by a total of three-quarters of a point. Yields on
longer maturities, however, were mostly unchanged from one year earlier,
reflecting the perceived deceleration in the U.S. economy.

Income-oriented sectors of the tax-free bond market were bid up in the
competition for excess income, and the Fund's holdings in hospital bonds, which
typically carry a significant yield premium, outperformed. In addition,
underweighting lower-yielding pre-refunded securities proved a successful
strategy.

Although surging tax receipts caused city and state credit quality to improve
markedly in fiscal 2004, Massachusetts bonds lagged under the weight of heavy
potential supply to finance school construction. Recent economic indicators
remain positive. The state's non-farm employment increased 2.0% since January
2004, slightly trailing the nation's 2.3% growth rate. The Commonwealth's
revenue collections reflect these positive economic trends, with collections
from all major taxes above budget as well as last year's results.

The gap between short- and long-term interest rates should shrink somewhat as
short rates rise, but will likely remain wider than average. We are gradually
moving toward a mix of shorter and longer bonds, known as a barbell structure,
but only when we can establish it without sacrificing income. The Fund's
sensitivity to interest rate changes closely tracks the benchmark index. We
remain focused on sectors and securities that produce excess yield as the
primary sources of long-term outperformance.

It has been our privilege to manage the Fund, and we thank you for your
continued support.

Sincerely,

/s/ Steven W. Harvey                    /s/ Christine L. Todd

AVERAGE ANNUAL TOTAL RETURNS REFLECT THE CHANGE IN THE VALUE OF AN INVESTMENT,
ASSUMING REINVESTMENT OF THE FUND'S DIVIDEND INCOME AND CAPITAL GAINS. THE
$100,000 LINE GRAPH AND THE FUND'S RETURNS DO NOT REFLECT THE DEDUCTION OF TAXES
THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND
SHARES. DURING PERIODS OF REIMBURSEMENT BY THE FUND'S INVESTMENT ADVISER (IF
APPLICABLE), THE FUND'S TOTAL RETURN WILL BE GREATER THAN IT WOULD BE HAD THE
REIMBURSEMENT NOT OCCURRED. PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE
PERFORMANCE.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
         STANDISH MELLON MASSACHUSETTS INTERMEDIATE TAX EXEMPT BOND FUND

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, and (2) ongoing costs, including management
fees and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2004 to September 30, 2004).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000.00=8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expenses
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs. Therefore, the
second line of the table is useful in comparing ongoing costs and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

     exempt from Massachusetts and federal income taxes, while seeking
     preservation of capital. The Fund seeks to achieve its objective by
     investing, under normal circumstances, at least 80% of net assets in tax
     exempt municipal securities of Massachusetts issuers and other qualifying
     issuers (such as Puerto Rico, the U.S. Virgin Islands, and Guam).

     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

     Tax-exempt bonds and notes are priced at fair value on the basis of
     valuations furnished by an independent pricing service or dealers, approved
     by the Trustees. Such services or dealers determine valuations for normal
     institutional-size trading units of such securities using methods based on
     market transactions for comparable securities and various relationships,
     generally recognized by institutional traders, between securities.

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions on shares of the Fund are declared daily from net investment
     income and distributed monthly. Distributions from capital gains, if any,
     will be distributed annually by the Fund. Distributions from net investment
     income and capital gains, if any, are automatically reinvested in
     additional shares of the applicable Fund unless the shareholder elects to
     receive them in cash. Distributions are recorded on the ex-dividend date.

     Income and capital gains 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 adjustments under the AICPA audit guide and
     distributions payable.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications among undistributed net
     investment income (loss), 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.

     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 investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
     Financial Corporation, for overall investment advisory, administrative
     services, and general office facilities, is paid at an annual rate of 0.40%
     of the Fund's average daily net assets. Standish Mellon voluntarily agreed
     to limit the total Fund operating expenses (excluding litigation,
     indemnification and other extraordinary expenses) to 0.65% of the Fund's
     average daily net assets for the year ended September 30, 2004. Pursuant to
     this agreement, for the year ended September 30, 2004, Standish Mellon
     voluntarily waived a portion of its advisory fee in the amount of $47,482.
     This agreement is voluntary and temporary and may be discontinued or
     revised by Standish Mellon at any time.

     Effective February 23, 2004, the Fund compensates Dreyfus Transfer, Inc., a
     wholly owned subsidiary of The Dreyfus Corporation, an affiliate of
     Standish Mellon, under a transfer agency agreement for providing personnel
     and facilities to perform transfer agency services for the Fund. Pursuant
     to this agreement the Fund was charged $3,500 during the year ended
     September 30, 2004.

     The Fund compensates Mellon Bank, N.A., an affiliate of Standish Mellon,
     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 $75,400 during the
     year ended September 30, 2004.

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

     The following table sets forth all remuneration paid to the Trustees by the
     Fund for the fiscal year ended September 30, 2004:

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     investments, for the year ended September 30, 2004 were $7,068,374 and
     $12,982,063, respectively. For the year ended September 30, 2004, the Fund

(4)  SHARES OF BENEFICIAL INTEREST:

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

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


     At September 30, 2004, the Fund had two shareholders of record owning
     approximately 29% and 10% of the Fund's outstanding shares. Investment
     activity of these shareholders could have a material impact on the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes all of its taxable income for its fiscal year.
     Dividends paid by the Fund from net interest earned on tax-exempt municipal
     bonds are not includable by shareholders as gross income for federal income
     tax purposes because the Fund intends to meet certain requirements of the
     Internal Revenue Code applicable to regulated investment companies which
     will enable the Fund to pay exempt-interest dividends.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2004, was as follows:


                                                  
     Unrealized appreciation                         $ 2,104,692
     Unrealized depreciation                             (44,650)
                                                     -----------
     Net unrealized appreciation/depreciation          2,060,042
     Undistributed ordinary income                        61,480
     Undistributed capital gains                         223,270
                                                     -----------
     Total distributable earnings                    $ 2,344,792
                                                     ===========
     Cost for federal income tax purposes            $41,732,283


     Tax character of distributions paid during the fiscal year ended September
     30, 2004, was as follows:

          Distributions paid from:           Amount
                                           ----------
                                        
              Tax-exempt income            $1,670,668
              Capital gains                 1,266,678


(6)  FINANCIAL INSTRUMENTS:

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


                                       15


                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
         STANDISH MELLON MASSACHUSETTS INTERMEDIATE TAX EXEMPT BOND FUND

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     Since the Fund may invest a substantial portion of its assets in issuers
     located in one state, it will be more susceptible to factors adversely
     affecting issuers of that state than would be a comparable general
     tax-exempt mutual fund.

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

     FUTURES CONTRACTS

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

     At September 30, 2004, the Fund held no outstanding futures contracts.

(7)  DELAYED DELIVERY TRANSACTIONS:

     The Fund may purchase securities on a "when-issued", "delayed delivery" or
     "forward commitment" basis. Delivery and payment for such securities
     typically take longer than the customary settlement periods. The payment
     obligation and interest rates on the securities are fixed at the time the
     Fund enters into such commitments, but interest will not accrue to the Fund
     until delivery of and payment for the securities. The Fund may receive
     compensation for such forgone interest. Although the Fund will only make
     commitments to purchase when-issued, delayed delivery or forward commitment
     securities with the intention of actually acquiring the securities, the
     Fund may sell the securities before the settlement date if deemed advisable
     by the investment adviser. The Fund offsets in its Statement of Assets and
     Liabilities the payables and receivables associated with the purchases and
     sales of when-issued, delayed delivery or forward commitment securities
     that have the same coupon, settlement date and broker. When-issued, delayed
     delivery or forward commitment securities that are purchased from or sold
     to different brokers are reflected as both payables and receivables in the
     Fund's Statement of Assets and Liabilities.

     Unless the Fund has entered into an offsetting agreement to sell the
     securities, cash or liquid obligations with a market value at least equal
     to the amount of the Fund's commitment will be segregated with the Fund's
     custodian bank. If the market value of these securities declines,
     additional cash or securities will be segregated daily so that the
     aggregate market value of the segregated securities equals the amount of
     the Fund's commitment.

     Securities purchased on a when-issued, delayed delivery or forward
     commitment basis may have a market value on delivery that is less than the
     amount paid by the Fund. The Fund may also sell portfolio securities on a
     delayed delivery basis. The market value of the securities when they are
     delivered may be more than the amount to be received by the Fund.

     At September 30, 2004 the Fund held a delayed delivery security. See
     Schedule of Investments for further detail.

(8)  LINE OF CREDIT:

     The Fund, other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio (the "Portfolio 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 facility fee,
     computed at an annual rate of .060 of 1% on the committed amount, is
     allocated ratably among the participating portfolios/funds at the end of
     each quarter. For the year ended September 30, 2004, the expense related to
     the facility fee was $1,334 for the Fund.

     During the year ended September 30, 2004, the Fund borrowed under the
     credit facility and incurred $140 of interest expense.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Investment Trust and the
Shareholders of Standish Mellon Massachusetts Intermediate Tax Exempt Bond Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Standish Mellon Massachusetts
Intermediate Tax Exempt Bond Fund (the "Fund") at September 30, 2004, and the
results of its operations, the changes in its net assets and the financial
highlights for each of the periods indicated, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at September 30, 2004 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2004.

The past 12 months have been largely positive ones for the financial markets, as
the economic expansion continued. However, as the year progressed, estimates of
the recovery's strength have been reined in, to the benefit of fixed income and
the detriment of stocks.

The S&P 500 finished 2003 and entered 2004 with a sharp 100-point climb to its
peak in March, fueled to a large degree by above-trend GDP growth and driven by
a potent mix of tax cuts, monetary policy and government spending. But the
momentum stalled, as the market dealt with the prospect of inflation and a new
tightening cycle by the Federal Reserve, and the uncertainties of a tight
presidential campaign. Since March, the S&P 500 has been largely range-bound,
except for booming oil stocks. Economic indicators increasingly painted a
picture of a slowdown to more normal growth, and corporate profits appeared
strong, but less robust than anticipated.

In the bond market, 2003 ended with much speculation about when and how the Fed
would end one of the longest stretches of easy monetary policy on record, which
had driven rates to historical lows. In the fall of 2003, the prospect of
deflation was still a factor in the Fed's deliberations, and was its stated
rationale for maintaining an accommodative stance. Soon, however, the Fed began
to refer to a "measured pace" of tightening. The market reacted by switching
gears dramatically, sending the 10-year U.S. Treasury note from 3.7% on March 16
to 4.9% on June 14. Since then, as the economic outlook softened, with
relatively tame inflation, yields have settled back to about 4%, roughly the
same as a year ago.

Looking ahead, it's clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash, and are being deliberate in boosting employment and
spending on plant and equipment, as federal stimulus is waning. Nevertheless,
business activity has some significant momentum, which should carry over into
2005, with reasonably strong profit growth and modest inflation.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

September 2004

Coupon income once again pushed municipal bond investment returns into positive
territory, more than offsetting the negative price impact of a modest increase
in shorter interest rates. For the year ended September 30, 2004, the Standish
Intermediate Tax Exempt Bond Fund produced a total return after expenses of
2.76%. This result trailed the benchmark performance index (Lehman Muni 3,5,7
and 10 Year Index) return of 2.87%.

Throughout the past year, bond market participants focused on how quickly the
Federal Reserve would hike short-term interest rates, and by how much. A steady
stream of strong employment and consumption data in early 2004 convinced
investors that the Fed would need to act aggressively to choke off any nascent
inflation. Consequently, all rates were pushed up in anticipation of the
pressures of a possibly overheating economy. The spike in yields was temporary,
and quickly reversed course as jobs and spending numbers weakened through the
summer months. By the end of the period, the Fed had abandoned its accommodative
policy, raising short rates by a total of three-quarters of a point. Yields on
longer maturities, however, were mostly unchanged from one year earlier,
reflecting the perceived deceleration in the U.S. economy.

Income-oriented sectors of the tax-free bond market were bid up in the
competition for excess income, and the Fund's holdings in hospital bonds, which
typically carry a significant yield premium, outperformed. In addition,
underweighting lower-yielding pre-refunded securities proved a successful
strategy. Security selection in the housing bonds also generated favorable
relative returns for the 12-month period. The Fund continues to hold a large
strategic weighting in this more defensive sector.

City and state credit quality improved markedly in fiscal 2004, driven primarily
by surging tax receipts. Ratings upgrades and favorable budget news proved
positive for California general obligation bond valuations in the third quarter.
And New York City's creditworthiness showed steady gains as the City's economy
rebounded, causing its bonds to outperform as well. We expect both California
and New York City will see further economic and fiscal gains, and are holding
large positions in each of these prominent credits in the Fund.

The gap between short- and long-term interest rates should shrink somewhat as
short rates rise, but will likely remain wider than average. We are gradually
moving toward a mix of shorter and longer bonds, known as a barbell structure,
but only when we can establish it without sacrificing income. The Fund's
sensitivity to interest rate changes closely tracks the benchmark index. We
remain focused on sectors and securities that produce excess yield as the
primary sources of long-term outperformance.

It has been our privilege to manage the Fund, and we thank you for your
continued support.

Sincerely,

AVERAGE ANNUAL TOTAL RETURNS REFLECT THE CHANGE IN THE VALUE OF AN INVESTMENT,
ASSUMING REINVESTMENT OF THE FUND'S DIVIDEND INCOME AND CAPITAL GAINS. THE
$100,000 LINE GRAPH AND THE FUND'S RETURNS DO NOT REFLECT THE DEDUCTION OF TAXES
THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND
SHARES. DURING PERIODS OF REIMBURSEMENT BY THE FUND'S INVESTMENT ADVISER (IF
APPLICABLE), THE FUND'S TOTAL RETURN WILL BE GREATER THAN IT WOULD BE HAD THE
REIMBURSEMENT NOT OCCURRED. PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE
PERFORMANCE.

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, and (2) ongoing costs, including management
fees and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2004 to September 30, 2004).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000.00=8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expenses
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs. Therefore, the
second line of the table is useful in comparing ongoing costs and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                STANDISH MELLON INTERMEDIATE TAX EXEMPT BOND FUND

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

     The objective of the Fund is to provide a high level of interest income
     exempt from federal income taxes, while seeking preservation of capital.
     The Fund seeks to achieve its objective by investing, under normal
     circumstances, at least 80% of net assets in tax exempt municipal
     securities issued by states, territories, and possessions of the United
     States, the District of Columbia and their political subdivisions, agencies
     and instrumentalities.

     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

     Tax-exempt bonds and notes are priced at fair value on the basis of
     valuations furnished by an independent pricing service or dealers, approved
     by the Trustees. Such services or dealers determine valuations for normal
     institutional-size trading units of such securities using methods based on
     market transactions for comparable securities and various relationships,
     generally recognized by institutional traders, between securities.

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions on shares of the Fund are declared daily from net investment
     income and distributed monthly. Distributions from capital gains, if any,
     will be distributed annually by the Fund. Distributions from net investment
     income and capital gains, if any, are automatically reinvested in
     additional shares of the applicable Fund unless the shareholder elects to
     receive them in cash. Distributions are recorded on the ex-dividend date.

     Income and capital gains 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 adjustments under the AICPA audit guide and
     distributions payable.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications among undistributed net
     investment income (loss), 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.

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

     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 investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
     Financial Corporation, for overall investment advisory, administrative
     services, and general office facilities, is paid at an annual rate of 0.40%
     of the Fund's average daily net assets. Effective January 28, 2004,
     Standish Mellon voluntarily agreed to limit the total Fund operating
     expenses (excluding litigation, indemnification and other extraordinary
     expenses) to 0.45% of the Fund's average daily net assets for the year
     ended September 30, 2004. Prior to that date the rate was 0.65%. Pursuant
     to this agreement, for the year ended September 30, 2004, Standish Mellon
     voluntarily waived a portion of its advisory fee in the amount of $180,781.
     This agreement is voluntary and temporary and may be discontinued or
     revised by Standish Mellon at any time.

     Effective February 23, 2004, the Fund compensates Dreyfus Transfer, Inc., a
     wholly owned subsidiary of Dreyfus, an affiliate of Standish Mellon, under
     a transfer agency agreement for providing personnel and facilities to
     perform transfer agency services for the Fund. Pursuant to this agreement
     the Fund was charged $3,500 during the year ended September 30, 2004.

     The Fund compensates Mellon Bank, N.A., an affiliate of Standish Mellon
     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 $102,617 during the
     year ended September 30, 2004.

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

     The following table sets forth all remuneration paid to the Trustees by the
     Fund for the fiscal year ended September 31, 2004:

     At September 30, 2004, the Fund had two shareholders of record owning
     approximately 42% and 10% of the Fund's outstanding shares. Investment
     activity of these shareholders could have a material impact on the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes all of its taxable income for its fiscal year.
     Dividends paid by the Fund from net interest earned on tax-exempt municipal
     bonds are not includable by shareholders as gross income for federal income
     tax purposes because the Fund intends to meet certain requirements of the
     Internal Revenue Code applicable to regulated investment companies which
     will enable the Fund to pay exempt-interest dividends.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2004, was as follows:

(6)  FINANCIAL INSTRUMENTS:

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

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

     FUTURES CONTRACTS

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

     At September 30, 2004, the Fund held no outstanding futures contracts.

     SWAP AGREEMENTS

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

     At September 30, 2004, the Fund had one swap agreement outstanding. See
     Schedule of Investments for detail.

(7)  DELAYED DELIVERY TRANSACTIONS:

     The Fund may purchase securities on a "when-issued", "delayed delivery" or
     "forward commitment" basis. Delivery and payment for such securities
     typically take longer than the customary settlement periods. The payment
     obligation and interest rates on the securities are fixed at the time the
     fund enters into such commitments, but interest will not accrue to the fund
     until delivery of and payment for the securities. The Fund may receive
     compensation for such forgone interest. Although the Fund will only make
     commitments to purchase when-issued, delayed delivery or forward commitment
     securities with the intention of actually acquiring the securities, the
     fund may sell the securities before the settlement date if deemed advisable
     by the investment adviser. The Fund offsets in its Statement of Assets and
     Liabilities the payables and receivables associated with the purchases and
     sales of when-issued, delayed delivery or forward commitment securities
     that have the same coupon, settlement date and broker. When-issued, delayed
     delivery or forward commitment securities that are purchased from or sold
     to different brokers are reflected as both payables and receivables in the
     Fund's Statement of Assets and Liabilities.

     Unless the Fund has entered into an offsetting agreement to sell the
     securities, cash or liquid obligations with a market value at least equal
     to the amount of the Fund's commitment will be segregated with the Fund's
     custodian bank. If the market value of these securities declines,
     additional cash or securities will be segregated daily so that the
     aggregate market value of the segregated securities equals the amount of
     the Fund's commitment.

     Securities purchased on a when-issued, delayed delivery or forward
     commitment basis may have a market value on delivery that is less than the
     amount paid by the fund. The Fund may also sell portfolio securities on a
     delayed delivery basis. The market value of the securities when they are
     delivered may be more than the amount to be received by the Fund.

     At September 30, 2004 the Fund held delayed delivery securities. See
     Schedule of Investments for further detail.

(8)  LINE OF CREDIT:

     The Fund, other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio (the "Portfolio 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 facility fee,
     computed at an annual rate of .060 of 1% on the committed amount, is
     allocated ratably among the participating portfolios/funds at the end of
     each quarter.

     For the year ended September 30, 2004, the expense related to the facility
     fee was $1,991 for the Fund.

     During the year ended September 30, 2004, the Fund had no borrowings under
     the credit facility.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Investment Trust and the
Shareholders of Standish Mellon Intermediate Tax Exempt Bond Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Standish Mellon Intermediate Tax
Exempt Bond Fund (the "Fund") at September 30, 2004, and the results of its
operations, the changes in its net assets and the financial highlights for each
of the periods indicated, in conformity with accounting principles generally
accepted in the United States of America. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2004 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2004.

The past 12 months have been largely positive ones for the financial markets, as
the economic expansion continued. However, as the year progressed, estimates of
the recovery's strength have been reined in, to the benefit of fixed income and
the detriment of stocks.

The S&P 500 finished 2003 and entered 2004 with a sharp 100-point climb to its
peak in March, fueled to a large degree by above-trend GDP growth and driven by
a potent mix of tax cuts, monetary policy and government spending. But the
momentum stalled, as the market dealt with the prospect of inflation and a new
tightening cycle by the Federal Reserve, and the uncertainties of a tight
presidential campaign. Since March, the S&P 500 has been largely range-bound,
except for booming oil stocks. Economic indicators increasingly painted a
picture of a slowdown to more normal growth, and corporate profits appeared
strong, but less robust than anticipated.

In the bond market, 2003 ended with much speculation about when and how the Fed
would end one of the longest stretches of easy monetary policy on record, which
had driven rates to historical lows. In the fall of 2003, the prospect of
deflation was still a factor in the Fed's deliberations, and was its stated
rationale for maintaining an accommodative stance. Soon, however, the Fed began
to refer to a "measured pace" of tightening. The market reacted by switching
gears dramatically, sending the 10-year U.S. Treasury note from 3.7% on March 16
to 4.9% on June 14. Since then, as the economic outlook softened, with
relatively tame inflation, yields have settled back to about 4%, roughly the
same as a year ago.

Looking ahead, it's clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash, and are being deliberate in boosting employment and
spending on plant and equipment, as federal stimulus is waning. Nevertheless,
business activity has some significant momentum, which should carry over into
2005, with reasonably strong profit growth and modest inflation.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

September 2004

The level of uncertainty in the equity markets has diverted investor attention
from investment fundamentals (e.g., earnings and earnings growth), to investment
behavior that is more emotionally driven. The current unsettled climate is
fostered by terrorist threats, the election puzzle, oil price uncertainty,
inflation fears and interest rate concerns. The economy continues to perform
relatively well and concerns about slowing economic growth and the resultant
slowing corporate profit growth seem to be somewhat overblown.

For the twelve months ended September 30, 2004 The Boston Company Small Cap Tax
Sensitive Equity Fund had a total return of 17.34%. This was well ahead of the
Russell 2000 Growth Index at 11.92% for the period. The Fund has had strong
relative performance in recent months as our holdings have been somewhat more
risk averse but, at the same time, it has participated fully in the recent
positive move. Within the markets, smaller stocks again performed better than
large stocks (the Russell 2000 was up 18.77% while the S&P 500 was up 13.87%),
and value has outpaced growth, especially in smaller stocks where the Russell
2000 Value Index was up more than twice that of the Russell 2000 Growth index.

Our risk averse approach continues to be a rewarding strategy in this very
volatile market environment. We are finding many companies we believe are truly
undervalued, not just cheap for an obvious reason. These potentially rewarding
opportunities seem to be a by-product of the prevailing market caution,
bordering on pessimism. The US economy slowed a bit in the summer as higher
energy prices and interest rates, along with the uncertainty surrounding the
election and its potential market impact, reduced consumer and investor
confidence and put a modest damper on the stock market. We continue to view the
economic landscape positively and expect corporate capital spending to remain
relatively strong.

Our best performing sectors relative to the index have been health care,
industrials and consumer discretionary. We expect strong earnings in these
sectors and continue to emphasize them in our portfolio allocation decisions.
Our energy holdings have been reduced at the margin as the stocks have done
well. We continue to carry a market weight in this sector because of our
long-term positive outlook for energy prices. Our emphasis here continues to be
on energy services and exploration companies.

We continue to deemphasize financials as most of these stocks are fully valued
in our view. Business momentum is neutral at best and rising interest rates will
further narrow spreads and put more pressure on earnings in coming quarters.
Stocks in the industrials sector are attractive because of the positive outlook
for corporate capital spending. We look for several more quarters of relatively
strong earnings from this group and remain significantly overweight here.


                                       2


Our general outlook remains positive. We continue to find many companies in our
research universe we believe are undervalued with strong fundamentals and good
earnings prospects. With a good chance for continued economic growth and modest
inflation, capital spending should be robust for several quarters. The major
concerns were highlighted earlier but we believe our fundamental approach,
emphasizing strong business momentum and undervaluation, will yield good returns
even in this more volatile equity environment.

AVERAGE ANNUAL TOTAL RETURNS REFLECT THE CHANGE IN THE VALUE OF AN INVESTMENT,
ASSUMING REINVESTMENT OF THE FUND'S DIVIDEND INCOME AND CAPITAL GAINS. THE
$100,000 LINE GRAPH AND THE FUND'S RETURNS DO NOT REFLECT THE DEDUCTION OF TAXES
THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND
SHARES. DURING PERIODS OF REIMBURSEMENT BY THE FUND'S INVESTMENT ADVISER (IF
APPLICABLE), THE FUND'S TOTAL RETURN WILL BE GREATER THAN IT WOULD BE HAD THE
REIMBURSEMENT NOT OCCURRED. PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE
PERFORMANCE.

             THE BOSTON COMPANY SMALL CAP TAX-SENSITIVE EQUITY FUND

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, and (2) ongoing costs, including management
fees and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2004 to September 30, 2004).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000.00=8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs. Therefore, the
second line of the table is useful in comparing ongoing costs and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
             THE BOSTON COMPANY SMALL CAP TAX-SENSITIVE EQUITY FUND

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 Tax-Sensitive Equity Fund (the "Fund") is a
     separate diversified investment series of the Trust.

     The objective of the Fund is to maximize after-tax total return, consisting
     of long-term growth of capital. The Fund seeks to achieve its objective by
     investing, under normal circumstances, at least 80% of net assets in equity
     securities of small capitalization U.S. companies.

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

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price, 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 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. Dividends representing a return of capital are
     reflected as a reduction of cost.

     C. DISTRIBUTIONS TO SHAREHOLDERS

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

     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 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.

     D. EXPENSES

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

     E. COMMITMENTS AND CONTINGENCIES

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

     F. 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 Fund's average daily net assets. For the
     year ended September 30, 2004, the Fund paid $949,430 in investment
     advisory fees to TBCAM.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of TBCAM, to provide personnel and facilities to perform
     transfer agency and certain shareholder services for the Fund. For these
     services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account
     and transaction based fees, as well as, out-of-pocket expenses. Pursuant to
     this agreement the Fund was charged $3,500 during the year ended September
     30, 2004.

     The Fund has contracted Mellon Bank, N.A. ("Mellon Bank"), a wholly owned
     subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to
     provide custody, fund administration and fund accounting services for the
     Fund. For these services, the Fund pays Mellon Bank a fixed fee plus asset
     and transaction based fees, as well as, out-of-pocket expenses. Pursuant to
     this agreement the Fund was charged $106,106 during the year ended
     September 30, 2004.

     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.

     The following table sets forth all remuneration paid to the Trustees for
     the Fund's fiscal year ended September 30, 2004:

(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:



                                                                        For the                For the

        Shares sold                                                     553,482                766,053

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

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


     At September 30, 2004, two shareholders of record held approximately 44%
     and 11% of the total outstanding shares of the Fund. Investment activity of
     these shareholders could have a material impact on the Fund.

     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 year ended September 30, 2004, the Fund received
     $242 in redemption fees.

(5)  FEDERAL TAXES:

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

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2004, was as follows:


                                                 
     Cost for federal income tax purposes           $108,070,932
                                                    ------------
     Unrealized appreciation                        $ 20,564,477
     Unrealized depreciation                          (2,703,248)
                                                    ------------
     Net unrealized appreciation/depreciation         17,861,229
                                                    ============
     Undistributed ordinary income                            82
     Capital loss carry-forward                       (2,406,360)


     At September 30, 2004, the Fund, for federal income tax purposes, has
     capital loss carryovers which will reduce the Fund's taxable income arising
     from net realized gain on investments, if any, to the extent permitted by
     the Internal Revenue Code and thus will reduce the amount of distributions
     to shareholders which would otherwise be necessary to relieve the Fund of
     any liability for federal income tax. Such capital loss carryovers are as
     follows:



                   Capital Loss
                    Carry Over                  Expiration Date

                          NOTES TO FINANCIAL STATEMENTS

(6)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

     The Fund did not enter into option transactions during the year ended
     September 30, 2004.

     FUTURES CONTRACTS

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

     At September 30, 2004, the Fund held financial futures contracts. See
     Schedule of Investments for further detail.

(7)  SECURITY LENDING:

     The Fund entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement Mellon Bank receives an agreed upon percentage
     of the net lending revenues. This compensation is a standard form of
     compensation received by securities lending agents with respect to
     non-affiliated entities.

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

     The Fund loaned securities during the year ended September 30, 2004
     resulting in $21,929 of security lending income. At September 30, 2004, the
     Fund had $5,986,620 worth of securities on loan.

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

(8)  LINE OF CREDIT:

     The Fund, and other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio Trust (the "Portfolio 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 facility fee, computed at an annual rate of .060 of 1% on the committed
     amount, is allocated ratably among the participating portfolios/funds at
     the end of each quarter. For the year ended September 30, 2004, the
     facility fee was $2,468.

     During the year ended September 30, 2004, the Fund had borrowings under the
     credit facility and incurred $72 of interest expense.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Investment Trust and the
Shareholders of The Boston Company Small Cap Tax-Sensitive Equity Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of The Boston Company Small Cap
Tax-Sensitive Equity Fund (the "Fund") at September 30, 2004 and the results of
its operations, the changes in its net assets, and the financial highlights for
each of the periods indicated, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2004 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2004.

The past 12 months have been largely positive ones for the financial markets, as
the economic expansion continued. However, as the year progressed, estimates of
the recovery's strength have been reined in, to the benefit of fixed income and
the detriment of stocks.

The S&P 500 finished 2003 and entered 2004 with a sharp 100-point climb to its
peak in March, fueled to a large degree by above-trend GDP growth and driven by
a potent mix of tax cuts, monetary policy and government spending. But the
momentum stalled, as the market dealt with the prospect of inflation and a new
tightening cycle by the Federal Reserve, and the uncertainties of a tight
presidential campaign. Since March, the S&P 500 has been largely range-bound,
except for booming oil stocks. Economic indicators increasingly painted a
picture of a slowdown to more normal growth, and corporate profits appeared
strong, but less robust than anticipated.

In the bond market, 2003 ended with much speculation about when and how the Fed
would end one of the longest stretches of easy monetary policy on record, which
had driven rates to historical lows. In the fall of 2003, the prospect of
deflation was still a factor in the Fed's deliberations, and was its stated
rationale for maintaining an accommodative stance. Soon, however, the Fed began
to refer to a "measured pace" of tightening. The market reacted by switching
gears dramatically, sending the 10-year U.S. Treasury note from 3.7% on March 16
to 4.9% on June 14. Since then, as the economic outlook softened, with
relatively tame inflation, yields have settled back to about 4%, roughly the
same as a year ago.

Looking ahead, it's clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash, and are being deliberate in boosting employment and
spending on plant and equipment, as federal stimulus is waning. Nevertheless,
business activity has some significant momentum, which should carry over into
2005, with reasonably strong profit growth and modest inflation.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

September 2004

The Boston Company International Small Cap Fund (the "International Small Cap
Fund") return for the twelve months ended September 30, 2004 was 33.35% versus
26.46% for its benchmark, the S&P Citigroup EMI ex. US index. The International
Small Cap Fund's 1 Year, 3 Year and 5 Year returns have exceeded the benchmark
by solid margins.

All EAFE markets were up this year, and all but Greece posted double-digit
annual returns, as measured in US dollars. Ireland proved to be the highest
performing market with a 108% return, due primarily to tremendous strength in
one stock, Elan, a pharmaceuticals company. Four other international equity
markets were up more than 50%. In general, energy producing countries benefited
at the relative expense of energy consuming countries. For example, oil rich
Norway witnessed its market produce annual returns of greater than 50%, while
oil dependent Japan's market was a relative laggard with only a 16.5% return for
the period.

From an economic sector perspective, it was an excellent year for energy stocks,
and a relative struggle for technology stocks. Energy stocks were up the most
with a return of 66%, buoyed by oil prices that remained much higher than
anticipated. Very strong demand, especially from developing markets, and supply
concerns, due to unrest in Iraq and elsewhere, combined to keep oil prices high.
Technology stocks were up only 6.5%, and were depressed by very intense price
competition, industry overcapacity, reluctance of buyers to invest in new
products, and valuations levels that still appear to be too high relative to
other sectors.

The International Small Cap Fund outperformed the index during the period,
largely due to our process of disciplined stock selection. Contribution to the
positive relative performance was broad based. The Fund had positive stock
selection versus the benchmark in 19 of 24 countries. In addition the Fund
outperformed the benchmark in eight of 10 economic sectors.

The portfolio continues to reflect our approach of investing in stocks of
companies that are attractively valued and exhibit improving business momentum.
The global economy is growing. Policy makers have begun the process of removing
the massive stimulus pumped into the system following the last recession and the
September 11 terrorist attacks. While policy has not yet moved into restrictive
territory, the combination of higher rates and higher oil prices may undermine
the strength of the economic expansion. Corporate profits are expected to grow,
but at a slower pace. It remains unclear whether investors will be encouraged by
the growth, or discouraged by the slowdown in the rate of growth. Overall,
valuation levels seem reasonable.

*COMBINED LP & MF PERFORMANCE

AVERAGE ANNUAL TOTAL RETURNS REFLECT THE CHANGE IN THE VALUE OF AN INVESTMENT,
ASSUMING REINVESTMENT OF THE FUND'S DIVIDEND INCOME AND CAPITAL GAINS. THE
$100,000 LINE GRAPH AND THE FUND'S RETURNS DO NOT REFLECT THE DEDUCTION OF TAXES
THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND
SHARES. DURING PERIODS OF REIMBURSEMENT BY THE FUND'S INVESTMENT ADVISER (IF
APPLICABLE), THE FUND'S TOTAL RETURN WILL BE GREATER THAN IT WOULD BE HAD THE
REIMBURSEMENT NOT OCCURRED. PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE
PERFORMANCE.

                 THE BOSTON COMPANY INTERNATIONAL SMALL CAP FUND

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, and (2) ongoing costs, including management
fees and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2004 to September 30, 2004).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000.00=8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expenses
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs. Therefore, the
second line of the table is useful in comparing ongoing costs and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

+    EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIO OF 1.27%,
     MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY
     183/366 (TO REFLECT THE ONE-HALF YEAR PERIOD). THE EXAMPLE REFLECTS THE
     COMBINED EXPENSES OF THE FUND AND THE MASTER PORTFOLIO IN WHICH IT INVESTS
     ALL ITS ASSETS.

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                 THE BOSTON COMPANY INTERNATIONAL SMALL CAP FUND

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 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 S&P
     Citigroup EMI Ex-U.S. Index and, to a limited extent, emerging markets. The
     value of the Fund's investment in the Portfolio reflects the Fund's
     proportionate interest in the net assets of the Portfolio (approximately
     96.6% at September 30, 2004). The performance of the Fund is directly
     affected by the performance of the Portfolio. The financial statements of
     the Portfolio are included elsewhere in this report and should be read in
     conjunction with the Fund's financial statements.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. 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 and redemptions
     in-kind. In 2004, the fund incurred a redemption in-kind which resulted in
     a realized gain of $2,404,435, which will be deferred indefinitely for tax
     purposes.

     Permanent book and tax basis differences relating to shareholder
     distributions, including distributions in kind, 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. and redemptions in-kind. In 2004, the
     fund incurred a redemption in-kind which resulted in a realized gain of
     $2,404,435, which will be deferred indefinitely for tax purposes.

     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.

(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.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of TBCAM, to provide personnel and facilities to perform
     transfer agency and certain shareholder services for the Fund. For these
     services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account
     and transaction based fees, as well as, out-of-pocket expenses. Pursuant to
     this agreement the Fund was charged $3,500 during the year ended September
     30, 2004.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     90 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading. The fee does
     not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2004, the Fund received
     $1,605 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.

     The following table sets forth all remuneration paid to the Trustees by the
     Fund for the fiscal year ended September 30, 2004. The fund also bears its
     pro rata share of the renumeration paid to the Trustees by the Portfolio.
     See Note 2 of the Portfolio's notes to financial statements which are

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Investment Trust and the
Shareholders of The Boston Company International Small Cap Fund:

In our opinion, the accompanying statement of assets and liabilities, and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
The Boston Company International Small Cap Fund (the "Fund") at September 30,
2004, the results of its operations, the changes in its net assets and the
financial highlights for each of the periods indicated, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of investment in the Portfolio at September
30, 2004 by correspondence with the custodian, provide a reasonable basis for
our opinion.

              THE BOSTON COMPANY INTERNATIONAL SMALL CAP PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 Salomon Smith
     Barney Extended Market Ex-U.S. Index and, to a limited extent, emerging
     markets.

     At September 30, 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 September 30, 2004, The Boston Company International
     Small Cap Fund and the Dreyfus Premier International Small Cap Fund held
     approximately 96.6% and 3.4% 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
- --------------------------------------------------------------------------------

     D. INCOME TAXES

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

     E. FOREIGN CURRENCY TRANSACTIONS

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

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

     F. INVESTMENT RISK

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

     G. COMMITMENTS AND CONTINGENCIES

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

     H. 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 1.00% of the Portfolio's average daily net assets. For
     the year ended September 30, 2004, the Portfolio paid $1,416,138 in
     investment advisory fees to TBCAM.

     The Portfolio has contracted Mellon Bank, N.A. ("Mellon Bank"), a wholly
     owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM,
     to provide custody, fund administration and fund accounting services for
     the Portfolio. For these services the Portfolio pays Mellon Bank a fixed
     fee plus fees that are asset and transaction based, as well as,
     out-of-pocket expenses. Pursuant to this agreement the Portfolio was
     charged $209,622 during the year ended September 30, 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.

     The following table sets forth all remuneration paid to the Trustees by the
     Portfolio for the fiscal year ended September 30, 2004:

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended September 30, 2004 were $182,962,215 and
     $98,297,342, respectively. For the year ended September 30, 2004, the
     Portfolio did not purchase or sell any long-term U.S. government
     securities.

(4)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the

(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:

              THE BOSTON COMPANY INTERNATIONAL SMALL CAP PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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 year ended
     September 30, 2004.

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     At September 30, 2004, the Portfolio did not hold any forward 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 September 30, 2004, the Portfolio held the
     following outstanding financial futures contracts:

     At September 30, 2004, the Portfolio held futures contracts. See Schedule
     of Investments for further details.

(6)  SECURITY LENDING:

     The Portfolio entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Portfolio's lending agent.
     Pursuant to this agreement the Mellon Bank receives an agreed upon
     percentage of the net lending revenues. This compensation is a standard
     form of compensation received by securities lending agents with respect to
     non-affiliated entities.

     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 year ended September 30, 2004
     resulting in $177,450 worth of security lending income. At September 30,
     2004, the Portfolio had securities valued at $19,274,168 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 facility fee,
     computed at an annual rate of .060 of 1% on the committed amount, is
     allocated ratably among the participating portfolios/funds at the end of
     each quarter. For the year ended September 30, 2004, the facility fee was
     $1,949.

     During the year ended September 30, 2004, the Portfolio had no borrowings
     under the credit facility.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Portfolio and Investors of The
Boston Company International Small Cap Portfolio:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of The Boston Company International
Small Cap Portfolio (the "Portfolio") at September 30, 2004 and the results of
its operations, the changes in its net assets, and the financial highlights for
each of the periods indicated, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Portfolio's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at September 30, 2004 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2004.

The past 12 months have been largely positive ones for the financial markets, as
the economic expansion continued. However, as the year progressed, estimates of
the recovery's strength have been reined in, to the benefit of fixed income and
the detriment of stocks.

The S&P 500 finished 2003 and entered 2004 with a sharp 100-point climb to its
peak in March, fueled to a large degree by above-trend GDP growth and driven by
a potent mix of tax cuts, monetary policy and government spending. But the
momentum stalled, as the market dealt with the prospect of inflation and a new
tightening cycle by the Federal Reserve, and the uncertainties of a tight
presidential campaign. Since March, the S&P 500 has been largely range-bound,
except for booming oil stocks. Economic indicators increasingly painted a
picture of a slowdown to more normal growth, and corporate profits appeared
strong, but less robust than anticipated.

In the bond market, 2003 ended with much speculation about when and how the Fed
would end one of the longest stretches of easy monetary policy on record, which
had driven rates to historical lows. In the fall of 2003, the prospect of
deflation was still a factor in the Fed's deliberations, and was its stated
rationale for maintaining an accommodative stance. Soon, however, the Fed began
to refer to a "measured pace" of tightening. The market reacted by switching
gears dramatically, sending the 10-year U.S. Treasury note from 3.7% on March 16
to 4.9% on June 14. Since then, as the economic outlook softened, with
relatively tame inflation, yields have settled back to about 4%, roughly the
same as a year ago.

Looking ahead, it's clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash, and are being deliberate in boosting employment and
spending on plant and equipment, as federal stimulus is waning. Nevertheless,
business activity has some significant momentum, which should carry over into
2005, with reasonably strong profit growth and modest inflation.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

September 2004

The level of uncertainty in the equity markets has diverted investor attention
from investment fundamentals (e.g., earnings and earnings growth) to investment
behavior that is more emotionally driven. The current unsettled climate is
fostered by terrorist threats, the election puzzle, oil price uncertainty,
inflation fears and interest rate concerns. The economy continues to perform
relatively well and concerns about slowing economic growth and the resultant
slowing corporate profit growth seem to be somewhat overblown.

For the twelve months ended September 30, 2004 The Boston Company Small Cap
Growth Fund-Institutional Class had a total return of 17.09% versus 11.92% for
the Russell 2000 Growth Index. The Boston Company Small Cap Growth Fund-Service
Class returned 16.76% as compared to the same benchmark. The Funds have had
strong relative performance in recent months as our holdings have been somewhat
more risk averse but, at the same time, they have participated fully in the
recent positive move. Within the markets, smaller stocks again performed better
than large stocks (the Russell 2000 was up 18.77% while the S&P 500 was up
13.87%), and value has outpaced growth, especially in smaller stocks where the
Russell 2000 Value Index was up more than twice that of the Russell 2000 Growth
index.

Our risk averse approach continues to be a rewarding strategy in this very
volatile market environment. We are finding many companies we believe are truly
undervalued, not just cheap for an obvious reason. These potentially rewarding
opportunities seem to be a by-product of the prevailing market caution,
bordering on pessimism. The US economy slowed a bit in the summer as higher
energy prices and interest rates, along with the uncertainty surrounding the
election and its potential market impact, reduced consumer and investor
confidence and put a modest damper on the stock market. We continue to view the
economic landscape positively and expect corporate capital spending to remain
relatively strong.

Our best performing sectors relative to the index have been health care,
industrials and consumer discretionary. We expect strong earnings in these
sectors and continue to emphasize them in our portfolio allocation decisions.
Our energy holdings have been reduced at the margin as the stocks have done
well. We continue to carry a market weight in this sector because of our
long-term positive outlook for energy prices. Our emphasis here continues to be
on energy services and exploration companies.

We continue to deemphasize financials as most of these stocks are fully valued
in our view. Business momentum is neutral at best and rising interest rates will
further narrow spreads and put more pressure on earnings in coming quarters.
Stocks in the industrials sector are attractive because of the positive outlook
for corporate capital spending. We look for several more quarters of relatively
strong earnings from this group and remain significantly overweight here.

Our general outlook remains positive. We continue to find many companies in our
research universe we believe are undervalued with strong fundamentals and good
earnings prospects. With a good chance for continued economic growth and modest
inflation, capital spending should be robust for several quarters. The major
concerns were highlighted earlier but we believe our fundamental approach,
emphasizing strong business momentum and undervaluation, will yield good returns
even in this more volatile equity environment.

AVERAGE ANNUAL TOTAL RETURNS REFLECT THE CHANGE IN THE VALUE OF AN INVESTMENT,
ASSUMING REINVESTMENT OF THE FUND'S DIVIDEND INCOME AND CAPITAL GAINS. THE
$100,000 LINE GRAPH AND THE FUND'S RETURNS DO NOT REFLECT THE DEDUCTION OF TAXES
THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND
SHARES. DURING PERIODS OF REIMBURSEMENT BY THE FUND'S INVESTMENT ADVISER (IF
APPLICABLE), THE FUND'S TOTAL RETURN WILL BE GREATER THAN IT WOULD BE HAD THE
REIMBURSEMENT NOT OCCURRED. PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE
PERFORMANCE.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                    THE BOSTON COMPANY SMALL CAP GROWTH FUND

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, and (2) ongoing costs, including management
fees and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2004 to September 30, 2004).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000.00=8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expenses
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs. Therefore, the
second line of the table is useful in comparing ongoing costs and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                    THE BOSTON COMPANY SMALL CAP GROWTH FUND

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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. As of September 30, 2004 the Fund owned
     approximately 100% of the Portfolio assets. 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

     Investment 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
     distributions 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 distributions, 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.

     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.

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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
     Institutional Class operating expenses (excluding brokerage commission,
     taxes and extraordinary expense) to 1.20% of the Institutional Class'
     average daily net assets and the Service Class operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses), 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 year ended September 30, 2004, TBCAM
     reimbursed the Institutional Class $46,892 and the Service Class $34,772
     for class-specific and Fund operating expenses. Prior to November 1, 2003,
     the voluntary expense limitation was 1.00% for Institutional Class shares
     and 1.25% for Service Class shares. This agreement is voluntary and
     temporary and may be discontinued or revised by TBCAM at any time.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of TBCAM, to provide personnel and facilities to perform
     transfer agency and certain shareholder services for the Fund. For these
     services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account
     and transaction based fees, as well as, out-of-pocket expenses. Pursuant to
     this agreement the Fund was charged $7,000 during the year ended September
     30, 2004.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     90 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading. The fee does
     not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2004, the Fund received $51
     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.

     The following table sets forth all remuneration paid to the Trustees by the
     Fund for the fiscal year ended September 30, 2004. The fund also bears its
     pro rata share of the renumeration paid to the Trustees by the Portfolio.
     See Note 2 of the Portfolio's notes to financial statements which are
     included elsewhere in this report.

(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
     year ended September 30, 2004 aggregated $9,465,370 and $11,682,896
     respectively.

(5)  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:



                                                                         For the                For the

     At September 30, 2004, one shareholder of record held approximately 12% of
     the total outstanding shares of the Institutional Class and one shareholder
     held of record approximately 100% of the total outstanding shares of the
     Service Class. Investment activity of these shareholders could have a
     material impact on the Fund.

(6)  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.

     As of September 30, 2004, the components of distributable earnings on a tax
     basis were as follows:

     Capital loss carry-forward                     (20,461,964)
                                                    -----------

     At September 30, 2004, the Fund, for federal income tax purposes, has
     capital loss carryovers which will reduce the Fund's taxable income arising
     from net realized gain on investments, if any, to the extent permitted by
     the Internal Revenue Code and thus will reduce the amount of distributions
     to shareholders which would otherwise be necessary to relieve the Fund of
     any liability for federal income tax. Such capital loss carryovers are as
     follows:



              CAPITAL LOSS

                    THE BOSTON COMPANY SMALL CAP GROWTH FUND

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Investment Trust and the
Shareholders of The Boston Company Small Cap Growth Fund:

In our opinion, the accompanying statement of assets and liabilities, and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
The Boston Company Small Cap Growth Fund (the "Fund") at September 30, 2004 and
the results of its operations, the changes in its net assets, and the financial
highlights for each of the periods indicated, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of investment in the Portfolio at September
30, 2004 by correspondence with the custodian, provide a reasonable basis for
our opinion.

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

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 September 30, 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
     September 30, 2004 was approximately 100%.

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

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price, 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 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") or its
     affiliates.

(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. Effective November 1, 2003 TBCAM
     voluntarily agreed to limit total Portfolio operating expenses (excluding
     brokerage commissions, taxes and extraordinary expenses) to 1.20% effective
     November 1, 2003, from 1.00% prior to that date, of the Portfolio's average
     daily net assets. Pursuant to this agreement, for the year ended September
     30, 2004, TBCAM voluntarily did not impose $9,471 of its investment
     advisory fee. This agreement is voluntary and temporary and may be
     discontinued or revised by TBCAM at any time.

     The Portfolio has contracted Mellon Bank, N.A. ("Mellon Bank"), a wholly
     owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM,
     to provide custody, fund administration and fund accounting services for
     the Portfolio. For these services the Portfolio pays Mellon Bank a fixed
     fee plus fees that are asset and transaction based, as well as,
     out-of-pocket expenses. Pursuant to this agreement the Portfolio was
     charged $86,325 during the year ended September 30, 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.

     The following table sets forth all remuneration paid to the Trustees for
     the Portfolio's fiscal year ended September 30, 2004:

     obligations, for the year ended September 30, 2004, were $50,161,289 and

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 year ended
     September 30, 2004.

     See the Schedule of Investments for securities on loan as of 9/30/04.

     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 September 30, 2004, the Portfolio held financial futures contracts. See
     Schedule of Investments for further detail.

(6)  SECURITY LENDING:

     The Portfolio entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Portfolio's Portfolio
     lending agent. Pursuant to this agreement Mellon Bank receives an agreed
     upon percentage of the net lending revenues. This compensation is a
     standard form of compensation received by securities lending agents with
     respect to non-affiliated entities.

                  THE BOSTON COMPANY SMALL CAP GROWTH PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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 year ended September 30, 2004
     resulting in $5,911 worth of security lending income. At September 30,
     2004, the Portfolio had $1,704,668 worth of securities on loan.

     See the Schedule of Investments for securities on loan as of September 30,
     2004.

(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 facility fee,
     computed at an annual rate of .060 of 1% on the commited amount, is
     allocated ratably among the participating portfolios/funds at the end of
     each quarter.

     For the year ended September 30, 2004, the facility fee was $716 for the
     Portfolio.

     During the year ended September 30, 2004, the Portfolio had borrowings
     under the credit facility. As a result of these borrowings the Portfolio
     incurred $38 of interest expense.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Master Portfolio and Investors of
The Boston Company Small Cap Growth Portfolio:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, and in all
material respects, the financial position of The Boston Company Small Cap Growth
Portfolio (the "Portfolio") at September 30, 2004 and the results of its
operations, the changes in its net assets, and the financial highlights for each
of the periods indicated, in conformity with accounting principles generally
accepted in the United States of America. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Portfolio's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2004 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2004.

The past 12 months have been largely positive ones for the financial markets, as
the economic expansion continued. However, as the year progressed, estimates of
the recovery's strength have been reined in, to the benefit of fixed income and
the detriment of stocks.

The S&P 500 finished 2003 and entered 2004 with a sharp 100-point climb to its
peak in March, fueled to a large degree by above-trend GDP growth and driven by
a potent mix of tax cuts, monetary policy and government spending. But the
momentum stalled, as the market dealt with the prospect of inflation and a new
tightening cycle by the Federal Reserve, and the uncertainties of a tight
presidential campaign. Since March, the S&P 500 has been largely range-bound,
except for booming oil stocks. Economic indicators increasingly painted a
picture of a slowdown to more normal growth, and corporate profits appeared
strong, but less robust than anticipated.

In the bond market, 2003 ended with much speculation about when and how the Fed
would end one of the longest stretches of easy monetary policy on record, which
had driven rates to historical lows. In the fall of 2003, the prospect of
deflation was still a factor in the Fed's deliberations, and was its stated
rationale for maintaining an accommodative stance. Soon, however, the Fed began
to refer to a "measured pace" of tightening. The market reacted by switching
gears dramatically, sending the 10-year U.S. Treasury note from 3.7% on March 16
to 4.9% on June 14. Since then, as the economic outlook softened, with
relatively tame inflation, yields have settled back to about 4%, roughly the
same as a year ago.

Looking ahead, it's clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash, and are being deliberate in boosting employment and
spending on plant and equipment, as federal stimulus is waning. Nevertheless,
business activity has some significant momentum, which should carry over into
2005, with reasonably strong profit growth and modest inflation.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------


September 2004

The level of uncertainty in the equity markets has diverted investor attention
from investment fundamentals (e.g., earnings and earnings growth), to investment
behavior that is more emotionally driven. The current unsettled climate is
fostered by terrorist threats, the election puzzle, oil price uncertainty,
inflation fears and interest rate concerns. The economy continues to perform
relatively well and concerns about slowing economic growth and the resultant
slowing corporate profit growth seem to be somewhat overblown.

For the twelve months ended September 30, 2004 The Boston Company Small Cap
Value Fund had a total return of 29.92%. This was well ahead of the Russell 2000
Value Index at 25.66% for the period. The Fund has had strong relative
performance in recent months as our holdings have been somewhat more risk averse
but, at the same time, it participated fully in the recent positive move. Within
the markets, smaller stocks again performed better than large stocks (the
Russell 2000 was up 18.77% while the S&P 500 was up 13.87%), and value has
outpaced growth, especially in smaller stocks where the Russell 2000 Value Index
was up more than twice that of the Russell 2000 Growth index.

Our value approach continues to be a rewarding strategy in this very volatile
market environment. We are finding many companies we believe are truly
undervalued, not just cheap for an obvious reason. These potentially rewarding
opportunities seem to be a by-product of the prevailing market caution,
bordering on pessimism.

The US economy slowed a bit in the summer as higher energy prices and interest
rates, along with the uncertainty surrounding the election and its potential
market impact, reduced consumer and investor confidence and put a modest damper
on the stock market. We continue to view the economic landscape positively and
expect corporate capital spending to remain relatively strong.

Our best performing sectors relative to the index have been health care and
information technology. We expect continued strength in these sectors and remain
overweight in both relative to the benchmark. Other overweight sectors include
consumer staples and industrials.

Our energy holdings have been reduced at the margin as the stocks have done
well. We continue to carry a market weight in this sector because of our
long-term positive outlook for energy prices. Our emphasis here continues to be
on energy services and exploration companies. We continue to deemphasize
financials as most of these stocks are fully valued in our view. Business
momentum is neutral at best and rising interest rates will further narrow
spreads and put more pressure on earnings in coming quarters. Stocks in the
industrials sector are attractive because of the positive outlook for corporate
capital spending. We look for several more quarters of relatively strong
earnings from this group and remain significantly overweight here.


                                       2


Our general outlook remains positive. We continue to find many companies in our
research universe we believe are undervalued with strong fundamentals and good
earnings prospects. With a good chance for continued economic growth and modest
inflation, capital spending should be robust for several quarters. The major
concerns were highlighted earlier but we believe our fundamental approach,
emphasizing strong business momentum and undervaluation, will yield good returns
even in this more volatile equity environment.

                     THE BOSTON COMPANY SMALL CAP VALUE FUND

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, and (2) ongoing costs, including management
fees and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2004 to September 30, 2004).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000.00=8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expenses
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs. Therefore, the
second line of the table is useful in comparing ongoing costs and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                     THE BOSTON COMPANY SMALL CAP VALUE FUND

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 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 92% at September 30, 2004). The performance of
     the Fund is directly affected by the performance of the Portfolio. The
     financial statements of the Portfolio are included elsewhere in this report
     and should be read in conjunction with the Fund's financial statements.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. 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 REITS
     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.

     E. Commitments and Contingencies

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

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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"), a wholly owned subsidiary
     of Mellon Institutional Asset Management, for such services. See Note 2 of
     the Portfolio's Notes to Financial Statements which are included elsewhere
     in this report.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of TBCAM, to provide personnel and facilities to perform
     transfer agency and certain shareholder services for the Fund. For these
     services the Fund pays Dreyus Transfer, Inc. a fixed fee plus per account
     and transaction based fees, as well as, out-of-pocket expenses. Pursuant to
     this agreement the Fund was charged $3,500 during the year ended September
     30, 2004.

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

     The following table sets forth all remuneration paid to the Trustees by the
     Fund for the fiscal year ended September 30, 2004. The fund also bears its
     pro rata share of the renumeration paid to the Trustees by the Portfolio.
     See Note 2 of the Portfolio's notes to financial statements which are
     included elsewhere in this report.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Investment Trust and the
Shareholders of The Boston Company Small Cap Value Fund:

In our opinion, the accompanying statement of assets and liabilities, and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
The Boston Company Small Cap Value Fund (the "Fund") at September 30, 2004, and
the results of its operations, the changes in its net assets and the financial
highlights for each of the periods indicated, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of investment in the Portfolio at September
30, 2004 by correspondence with the custodian, provide a reasonable basis for
our opinion.

(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 September 30, 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
     September 30, 2004, The Boston Company Small Cap Value Fund and the Dreyfus
     Premier Small Cap Equity Fund held approximately 92% and 8% 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.

     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.

     C. SECURITIES TRANSACTIONS AND INCOME

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

     D. INCOME TAXES

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

     E. 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.

     out-of-pocket expenses. Pursuant to this agreement the Portfolio was
     charged $73,447 during the year ended September 30, 2004.

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

                  THE BOSTON COMPANY SMALL CAP VALUE PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(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 year ended
     September 30, 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 September 30, 2004, the Portfolio held no outstanding financial futures
     contracts.

(6)  SECURITY LENDING:

     The Portfolio entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Portfolio lending agent.
     Pursuant to this agreement the Mellon Bank receives an agreed upon
     percentage of the net lending revenues. This compensation is a standard
     form of compensation received by securities lending agents with respect to
     non-affiliated entities.

     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 Fund loaned securities during the year ended September 30, 2004
     resulting in security lending income of $24,999. At September 30, 2004, the
     Fund had $3,122,542 worth of securities on loan.

     See Schedule of Investments for further detail on the security positions 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 0.60 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 year ended September 30, 2004, the
     commitment fee was $1,038 for the Portfolio.

     During the year ended September 30, 2004 the Portfolio had borrowed under
     the credit facility incurring $54 of interest expense.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Mellon Institutional Funds Master Portfolio and Investors of
The Boston Company Small Cap Value Portfolio:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of The Boston Company Small Cap Value
Portfolio (the "Portfolio") at September 30, 2004, and the results of its
operations, the changes in its net assets, and the financial highlights for each
of the periods indicated, in conformity with accounting principles generally
accepted in the United States of America. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Portfolio's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2004 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.
