Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

Funds. Please feel free to contact us with questions or comments.

            STANDISH MELLON OPPORTUNISTIC EMERGING MARKETS DEBT FUND

                       Management Discussion and Analysis
                                  December 2003

The Emerging Market debt asset class performed well in 2003, due to both a
supportive environment for risky assets and to fundamental improvements in the
economic condition of many emerging market countries. The widely followed JP
Morgan EMBI Plus returned 28.82% for the year, while the more diversified JP
Morgan EMBI Global managed a 25.67% return. The year 2003 was the second full
year for the Opportunistic Emerging Market Fund and it returned 28.82%, over 3%
ahead of its EMBI Global benchmark. Ecuador was the best performing market with
a return of 101.48%; the country benefited from strong oil prices and good
policy implementation by the government. Other notable performers included
Brazil, Nigeria and Uruguay, all with returns above 50%. The worst performing
market and the only market to produce a negative return was the Dominican
Republic; it declined 15.33% in 2003 as a banking crisis negatively impacted the
economy in the midst of an election season. Other key markets such as Mexico and
Russia returned 11.56% and 22.38%, respectively. Argentina's bond prices also
managed to bounce back after a difficult few years and return 19.05%.

Emerging market debt was driven by three important factors for most of 2003: the
US economic outlook, the performance of the Brazilian authorities, and new
inflows into the asset class. In the first half of the year, the US economy and
Brazil's reform progress had a very supportive impact on the asset class. The US
was continuing its economic recovery but was still showing anemic signs of
growth. This kept interest rates low and pushed investors to look for higher
yields in sectors such as emerging markets debt. Meanwhile, the newly elected
Lula government in Brazil took action to reduce inflation, maintain tight fiscal
policy, and tackle much needed reform of the social security and tax systems.
This pushed spreads on Brazil bonds lower and helped other high yielding credits
in Latin America to rally as well. During this period spreads on the EMBI+
narrowed about 200 bp.

In late June the Federal Reserve cut rates by 25 basis points but disappointed
the markets with their language change in the accompanying statement. The
Treasury market subsequently began selling off by over 100 bp over the next two
months. This negatively affected emerging markets spreads as investors
remembered the fallout from the 1994 Mexico crisis that was in part caused by a
rise in Treasury yields. Spreads remained volatile until the September, when
weak inflation and employment growth indicators caused the Fed to stress that
interest rates were likely to be kept at low levels for some time. Once US
Treasury rates stabilized, emerging market spreads continued to contract,
falling by another 100bp by the end of the year. Throughout the year but
especially in the second half, new inflows into the asset class from
institutional and retail investors helped keep bond prices well supported.

Fund positioning during the year emphasized overweights in the higher yielding
countries such as Brazil, Ecuador, Venezuela and Colombia. After four years of
dramatic tightening in Russian spreads due to strong policy implementation and
favorable oil prices, we reduced our allocation to Russia early in the year.
However, in summer Russian credit spreads widened on concerns that the
government's prosecution of the powerful Yukos oil company chairman represented
a wider assault


                                       3


on capitalism. We used that opportunity to increase our positioning. One area of
disappointment was our overweight in the Dominion Republic, which was negatively
affected by a banking scandal and poor fiscal results.

In 2004 we expect the first half of the year to be somewhat of a continuation of
the trends in 2003 with the Federal Reserve on hold and continued credit
improvement in many emerging markets. During the second half of the year the
outlook is more cautious as we expect the Federal Reserve to consider a change
in policy which is likely to impact all fixed income assets including emerging
market debt. Other factors such a large decline in the value of the US dollar,
another terrorist strike or a significant change in the economic policies of a
dominant emerging market country could pose challenges during the course of the
year.

We thank you for your continued support.

/s/ John L. Peta

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
            STANDISH MELLON OPPORTUNISTIC EMERGING MARKETS DEBT 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 Opportunistic Emerging Markets Debt Fund (the "Fund") is a
     separate non-diversified investment series of the Trust.

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

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

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

     B. REPURCHASE AGREEMENTS

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

     C. SECURITIES TRANSACTIONS AND INCOME

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

                                        14


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

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

     recorded on the identified cost basis. The Fund does not isolate that
     portion of the results of operations resulting from changes in foreign
     exchange rates on investments from the fluctuations arising from changes in
     market prices of securities held. Such fluctuations are included with the
     net realized and unrealized gain or loss from investments. Net realized
     gains and losses on foreign currency transactions represent gains and
     losses on disposition of foreign currencies and forward foreign currency
     exchange contracts, currency gains and losses realized between the trade
     and settlement dates on securities transactions, and the difference between
     the amount of investment income and foreign withholding taxes recorded on
     the Fund's books and the U.S. dollar equivalent amounts usually received or
     paid.

     D. FOREIGN CURRENCY TRANSACTIONS

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

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

     E. INVESTMENT RISK

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

     F. DISTRIBUTIONS TO SHAREHOLDERS

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

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

     G. EXPENSES

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

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

     H. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
     Financial Corporation, for overall investment advisory and administrative
     services, and general office facilities, is paid monthly at the annual rate
     of 0.50% of the Fund's average daily net assets. Standish Mellon
     voluntarily agreed to limit total Fund operating expenses (excluding
     brokerage commissions, taxes and extraordinary expenses) to 0.30% of the
     Fund's average daily net assets for the year ended December 31, 2003.
     Pursuant to this agreement, for the year ended December 31, 2003, Standish
     Mellon voluntarily did not impose $46,799 of its investment advisory fee
     and reimbursed the Fund for $105,675 of its operating expenses. This
     agreement is voluntary and temporary and may be discontinued or revised by
     Standish Mellon at any time.

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

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended December 31, 2003 were as follows:



                                                                      PURCHASES      SALES

(4)  SHARES OF BENEFICIAL INTEREST:

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

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the

       Accumulated gains                                                 41,551
       Cost for federal income tax purposes                         $15,301,178

      The tax character of distributions paid during the fiscal year ended
      December 31, 2003, was as follows:

                                                                       AMOUNT

       Distributions paid from:
         Ordinary income                                             $1,697,933
         Accumulated gains                                               46,884

(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.

     At December 31, 2003, the Fund had segregated sufficient securities for the

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     FUTURES CONTRACTS

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

     At December 31, 2003, the Fund held no outstanding financial futures
     contracts.

(7)  SECURITY LENDING:

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

     The Fund loaned securities during the year ended December 31, 2003
     resulting in security lending income. At December 31, 2003, the Fund had no
     securities on loan.

(8)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

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

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

     The Fund entered into no such transactions during the year ended December
     31, 2003.

     present fairly, in all material respects, the financial position of Mellon
     Institutional Funds Investment Trust: Standish Mellon Opportunistic
     Emerging Markets Debt Fund (formerly, Standish Opportunistic Emerging
     Markets Debt Fund) (the "Fund") at December 31, 2003, 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 auditing standards generally accepted in the United States
     of America, which 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 December 31, 2003 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
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

Funds. Please feel free to contact us with questions or comments.

               STANDISH MELLON INTERNATIONAL FIXED INCOME FUND II

                       Management Discussion and Analysis
                                  December 2003

International bond markets produced modest, positive returns in 2003in local
currency terms. However, in U.S. dollar terms the returns were significantly
higher due to the dramatic decline in the U.S. dollar. The Standish Mellon
International Fixed Income Fund II returned 21.51% for the year, after all
expenses, compared to 18.63% for our benchmark, the JP Morgan Non-U.S.
Government Bond Index.

Global bond market returns had two distinct phases during 2003 that were driven
by a series of economic, financial and geopolitical developments. During the
first half of the year, bond markets were generally strong, led by the U.S.
market. The global economy was weak, although there were signs of recovery, and
financial market participants were concerned about the possibility of deflation,
particularly in the U.S. The Iraq war and concern about North Korea's nuclear
weapons program further weighed on confidence and the growth outlook. In
addition, financial market scandals caused some investors to abandon riskier
assets such as stocks. Bonds looked like a safe bet.

During the second half of the year, global growth accelerated and confidence
returned to financial markets. The heavy fighting was over in Iraq and progress
was being made on the Korean Peninsula. The Federal Reserve had lowered rates to
their lowest level since 1958 and the combination of low interest rates and
fiscal stimulus was taking hold. The health of global companies was improving
with increasing profits and declining credit spreads. Equities were rallying
globally as were emerging market stocks and bonds. As the fear of deflation
faded, bond yields rose dramatically from the mid-year lows.

The range of returns in local terms for government bond markets as measured by
the JP Morgan Government Bond Indices was modest for the year with only 684 b.p.
separating the best market Canada (+6.04%) from the worst, Japan (-0.80%). The
U.S. component of the index returned 2.44% while European markets returned
3.76%. The U.S. dollar fell relative to all major currencies last year with the
declines ranging from 33.80% relative to the Australian dollar to 10.73%
relative to the Japanese yen. Although government bond returns were modest in
2003, corporate and emerging market bonds performed quite well. The higher
yielding segments of the bond market produced the best returns with high yield
corporate bonds and emerging market bond indices recording returns in excess of
20%. The U.S. dollar fell during the year as the mix of loose fiscal and
monetary policy and the large current account deficit made the currency
unattractive to global investors.

During this period of U.S. dollar weakness, the Fund has not been able to make
regular distributions of investment income. This is due to our policy of hedging
most of our currency exposures back to U.S. dollars. Although this policy
results in less volatility in total return over time than if the portfolio were
unhedged, currency volatility can have a


                                       3


significant effect on the Fund's investment income. In periods when the dollar
declines as it has over the past two years, the losses from the currency hedging
activity offset the investment income of the portfolio. Conversely, when the
dollar appreciates, our currency hedging activity typically generates gains that
enhance the investment income of the Fund. Another way to view this is that much
of the Fund's reported total return -which has been very strong compared to the
Index -- is classified as capital appreciation within the portfolio.

The Fund outperformed its benchmark during the year. Our position in investment
grade and high yield corporate bonds and emerging market securities was the
largest positive contributor relative to our benchmark. Our country selection
was also positive as we were overweighted European markets and zero weighted in
Japan. Our currency exposure was positive for the year relative to the benchmark
as we had established positions in the Euro and the Australian, New Zealand and
Canadian dollars relative to the U.S. dollar and all those positions contributed
positively in 2003.

Our outlook for 2004 is favorable for international bonds. We believe that the
performance of global economies will be mixed in the coming year with the U.S.
growing above trend, Japan on trend and Europe below. Government bond yields in
the U.S. will be biased upwards but opportunities for value-added can be found
in European bonds as the European Central Bank is likely to lag any moves by the
Fed to increase interest rates. Non-government sectors such as corporate and
emerging bonds offer value in 2004 as credit quality improves. However, the
excess returns are likely to be more modest than in 2003.

We appreciate your continued support and look forward to working on your behalf
over the next year.

/s/ W. Charles Cook

     the Fund for all or a portion of its operating expenses. If this voluntary

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

               STANDISH MELLON INTERNATIONAL FIXED INCOME FUND II

                         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 International Fixed Income Fund II (the "Fund") is a
     separate non-diversified investment series of the Trust.

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

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

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

     B. REPURCHASE AGREEMENTS

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

     C. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method on
     long-term debt securities. Realized gains and losses from securities sold
     are recorded on the identified cost basis. The Fund does not

     isolate that portion of the results of operations resulting from changes in
     foreign exchange rates on investments from the fluctuations arising from
     changes in market prices of securities held. Such fluctuations are included
     with the net realized and unrealized gain or loss from investments. Net
     realized gains and losses on foreign currency transactions represent gains
     and losses on disposition of foreign currencies and forward foreign
     currency exchange contracts, currency gains and losses realized between the
     trade and settlement dates on securities transactions, and the difference
     between the amount of investment income and foreign withholding taxes
     recorded on the Fund's books and the U.S. dollar equivalent amounts usually
     received or paid.

     D. FOREIGN CURRENCY TRANSACTIONS

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

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

     E. INVESTMENT RISK

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

     F. DISTRIBUTIONS TO SHAREHOLDERS

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

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

     G. EXPENSES

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

     H. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
     Financial Corporation, for overall investment advisory and administrative
     services, and general office facilities is paid monthly at the annual rate
     of 0.40% of the Fund's average daily net assets. Standish Mellon
     voluntarily agreed to limit the Fund's total annual operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     0.55% of the Fund's average daily net assets for the year ended December
     31, 2003. Pursuant to this agreement, for the year ended December 31, 2003,
     Standish Mellon voluntarily did not impose $93,938 of its investment
     advisory fee and reimbursed the Fund for $81,282 of its operating expenses.
     This agreement is voluntary and temporary and may be discontinued or
     revised by Standish Mellon at any time.

     Effective January 28, 2003, the Fund began imposing a redemption fee of 2%
     of the net asset value of the shares, with certain exceptions, which are
     redeemed or exchanged less than 90 days from the day of their purchase. The
     redemption fee is paid directly to the Fund, and is designed to offset
     brokerage commissions, market impact, and other costs associated with
     short-term trading in the Fund. The fee does not apply to shares that are
     acquired through reinvestment of distributions. For the period ended
     December 31, 2003, the Fund received no redemption fees.

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

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     investments, for the year ended December 31, 2003 were as follows:

(4)  SHARES OF BENEFICIAL INTEREST:

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

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

     At December 31, 2003, two shareholders held of record approximately 65% and
     14% of the total outstanding shares of the Fund.

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

(5)  FEDERAL TAXES:

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

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2003 was as follows:

         Unrealized depreciation                                              (53,762)
                                                                          -----------
         Net unrealized appreciation/depreciation                           2,542,733
         Undistributed ordinary income                                         21,739
         Accumulated losses                                                  (768,911)
         Cost basis of investments for federal income tax purposes        $20,892,645


     At December 31, 2003, the Fund, for federal income tax purposes had 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. The capital loss carryovers are $67,233
     and $686,115 which expire on December 31, 2009 and 2010, respectively.

     The Fund elected to defer to its fiscal year ending December 31, 2004
     $15,563 of losses recognized during the period November 1, 2003 to December
     31, 2003.

     The tax character of distributions paid during the fiscal year ended
     December 31, 2003, was as follows:

                                                                       AMOUNT
                                                                     ----------
         Distributions paid from:
           Ordinary income                                           $3,060,410
                                                                     ----------

(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.

     FORWARD CURRENCY EXCHANGE CONTRACTS

     The Fund may enter into forward foreign currency and cross currency
     exchange contracts for the purchase or sale of a specific foreign currency
     at a fixed price on a future date. Risks may arise upon entering these
     contracts from the potential inability of counterparties to meet the terms
     of their contracts and from unanticipated movements in the value of a
     foreign currency relative to the U.S. dollar and other foreign currencies.
     The forward foreign currency and cross currency exchange contracts are
     marked to market using the forward foreign currency rate of the underlying
     currency and any gains or losses are recorded for financial statement
     purposes as unrealized until the contract settlement date or

     used by the Fund primarily to protect the value of the Fund's foreign
     securities from adverse currency movements. Unrealized appreciation and
     depreciation of forward currency exchange contracts is included in the
     Statement of Assets and Liabilities.

     FUTURES CONTRACTS

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

     At December 31, 2003, the Fund held the following futures contracts:

     INTEREST RATE SWAP CONTRACTS

     Interest rate swaps involve the exchange by the Fund with another party of
     their respective commitments to pay or receive interest, e.g., an exchange
     of floating rate payments for fixed rate payments with respect to a
     notional amount of principal. Credit and market risk exist with respect to
     these instruments. If forecasts of interest rates and other market factors
     are incorrect, investment performance will diminish compared to what
     performance would have been if these investment techniques were not used.
     Even if the forecasts are correct, there are risks that the positions may
     correlate imperfectly with the asset or liability being hedged, a liquid
     secondary market may not always exist, or a counterparty to a transaction
     may not perform. The Fund expects to enter into these transactions
     primarily for hedging purposes including, but not limited to, preserving a
     return or spread on a particular investment or portion of its portfolio,
     protecting against currency fluctuations, as a duration management
     technique or protecting against an increase in the price of securities the
     Fund anticipates purchasing at a later date. Interest rate swaps are marked
     to market daily based upon quotations from market makers and the change, if
     any, is recorded as unrealized gain or loss. Payments made or received are
     included as part of interest income. Gains and losses are realized upon the
     expiration or closing of the swap contracts.

     The Fund entered into no such transactions during the year ended December
     31, 2003.

(7)  SECURITY LENDING:

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

     The Fund loaned securities during the year ended December 31, 2003
     resulting in security lending income. At December 31, 2003, the Fund had no
     securities on loan.

     DELAYED DELIVERY TRANSACTIONS:

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

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

     to the settlement date, which risk is in addition to the risk of the
     decline in the value of the Fund's other assets. Unsettled TBA purchase
     commitments are valued at the current market value of the underlying
     securities, according to the procedures described under "Investment
     security valuations" above.

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

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

     At December 31, 2003, the Fund did not have any delayed delivery
     transactions.

     Shareholders of Standish Mellon International Fixed Income Fund II:

     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 Mellon
     Institutional Funds Investment Trust: Standish Mellon International Fixed
     Income Fund II (formerly, Standish International Fixed Income Fund II) (the
     "Fund"), at December 31, 2003, 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
     auditing standards generally accepted in the United States of America,
     which 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 include confirmation of securities at
     December 31, 2003, 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
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

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

                                  December 2003

The year 2003 can be broken into two distinctly different environments for the
financial markets. The first half of the year was characterized by the war in
Iraq and a generally weak economy. The second half saw a renewed optimism in the
economy and was highlighted by a moderate rise in interest rates and a strong
equity market. The fixed income market had mixed results during the year, strong
during the first half, weaker during the second. In this mixed environment
Standish Mellon's disciplined approach to investing provided excellent relative
returns. The Standish Mellon Short-Term Fixed Income Fund returned 2.62% for the
year, surpassing the Merrill Lynch 1-3 year Treasury index which returned 1.90%.
On an absolute basis, both the return of the Fund and its benchmark are low due
to the historically low levels of short-term interest rates.

The year started on a cautious note. Early in the first quarter, the war in Iraq
seemed more likely every day and it appeared that the entire economy was waiting
on some resolution to this uncertainty. Consumer spending continued to be
strong, but there were few other bright spots. As the war commenced and was
successfully resolved, some of the uncertainty was eliminated and the stock
market improved. However, through April and May, the lack of any bounce in the
economy led people to speculate that a declining economic, deflationary
environment was possible and that drastic measures might need be taken to spark
the economy. During this time, interest rates declined to historically low
levels. It was speculated that the Federal Reserve might drop its overnight
funds target to well below 1% and even buy long-term Treasury securities to
reduce long-term interest rates. In June, the rates on two-year Treasury notes
reached a historical low of 1.08%, down nearly 50 basis points from the
beginning of the year. Longer-term interest rates declined even more
dramatically.

The Fed did eventually lower its overnight target rate to 1.00% in late June.
Although this action moved short-term rates to their lowest level yet, the move
was not as dramatic as originally expected. At the same time, economic news
began to indicate stronger growth, particularly in the capital goods sector.
This news led to a rapid increase in long-term interest rates during the summer.
While very-short term rates were held stable by the 1.00% overnight Fed Funds
target, longer-term rates began to anticipate an eventual tightening by the Fed.
The yield of the two-year note rose to over 2.10% by early September. Since that
time, the economy has continued to strengthen and the stock market has risen in
step. The bond market has also improved somewhat as the inflationary pressures
have not yet reappeared and the Fed has expressed reluctance to raising rates.
Ironically, the two-year Treasury note ended the year at roughly 1.60%, the same
level as it began the year.

In this back and forth interest rate environment, the spread sectors in the
fixed-income market continued to outperform. The deleveraging of corporations
from the prior few years and the gradually improving economy led credit spreads
to narrow to levels not


                                       3


seen since 1997. This spread narrowing was particularly noteworthy in lesser
quality names such as those rated BBB and below.

The performance of the Fund was helped during the year by its use of high
quality spread paper. High quality spread paper, such as corporate notes and
asset-backed securities, will continue to represent a major portion of the Fund
in the coming year. Historically the Fund has been managed relatively close to
its benchmark's duration and we anticipate this will continue in the future.

We would also like to note that as of March 31, 2003, portfolio management of
the Standish Mellon Short-Term Fixed Income Fund changed from David Hertan to
Laurie Carroll and Johnson Moore. As you may recall, as of July 1, Standish
Mellon in Boston combined with two affiliates within Mellon: Mellon Bond
Associates and Certus Asset Advisors. The Fund had been managed by Mr. Hertan
from the Boston office. In conjunction with the combination, all short-term
asset management was relocated in the Pittsburgh office, under Ms. Carroll and
Mr. Moore.

We remain committed to our disciplined approach with high quality fundamental
research to generate the strong relative returns we have achieved in the past.
We appreciate the continued support of our shareholders.


Sincerely,

/s/ Laurie A. Carroll           /s/ Johnson S. Moore

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

Net investment income per share(1)                            $ 0.40      $ 0.75  $  1.07   $  1.21  $  1.12

(a)  The Fund has adopted the provisions of the revised AICPA Audit and
     Accounting Guide for Investment Companies effective January 1, 2001 and
     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to increase net investment income per share by less
     than $0.001, decrease net realized and unrealized gains and losses per
     share by less than $0.001 and increase the ratio of net investment income
     to average net assets by less than 0.01%. Per share data and
     ratios/supplemental data for the periods prior to January 1, 2001 have not
     been restated to reflect this change in presentation.
(1)  Calculated based on average shares outstanding.
(2)  The amount shown for a share outstanding does not correspond with the
     aggregate net realized and unrealized gain/loss for the period due to the
     timing of purchases and redemptions of Fund shares in relation to the
     fluctuating market values of the Fund.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                  STANDISH MELLON SHORT-TERM FIXED INCOME 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 Short-Term Fixed Income Fund (the "Fund") is a separate
     diversified investment series of the Trust.

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

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

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

     B. REPURCHASE AGREEMENTS

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

     C. SECURITIES TRANSACTIONS AND INCOME

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

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

     D. DISTRIBUTIONS TO SHAREHOLDERS

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

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

     E. EXPENSES

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

     F. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
     Financial Corporation, for overall investment advisory, administrative
     services, and general office facilities, is paid monthly at the annual rate
     of 0.30% of the Fund's average daily net assets. Standish Mellon
     voluntarily agreed to limit total Fund operating expenses (excluding
     brokerage commissions, taxes and extraordinary expenses) to 0.30% of the
     Fund's average daily net assets for the year ended December 31, 2003.
     Pursuant to this agreement, for the year ended December 31, 2003, Standish
     Mellon voluntarily did not impose $39,204 of its investment advisory fee
     and reimbursed the Fund for $98,328 of its operating expenses. This
     agreement is voluntary and temporary and may be discontinued or revised by
     Standish Mellon at any time.

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

     At December 31, 2003, two shareholders held of record approximately 65% and
     13% of the total outstanding shares of the Fund. A significant portion of
     the Fund's shares are beneficially owned by fiduciary accounts over which
     Standish Mellon and its affiliates have either sole or joint investment
     discretion. Investment activity of these shareholders could have a material
     impact on the Fund.

(5)  FEDERAL TAXES:

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

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2003 were as follows:

         Unrealized appreciation                                     $   72,237

(6)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

     The Fund entered into no such transactions during the year ended December
     31, 2003.

     FUTURES CONTRACTS

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

     The Fund entered into no such transactions during the year ended December
     31, 2003.

(7)  SECURITY LENDING:

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

     The Fund loaned securities during the year ended December 31, 2003
     resulting in security lending income. At December 31, 2003, the Fund had no
     securities on loan.

(8)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

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

     At December 31, 2003, the Fund did not have any delayed delivery
     transactions.

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon Short-Term Fixed Income 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 Mellon
     Institutional Funds Investment Trust: Standish Mellon Short-Term Fixed
     Income Fund (formerly, Standish Short-Term Fixed Income Fund) (the "Fund"),
     at December 31, 2003, 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 auditing standards generally
     accepted in the United States of America, which 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 December 31, 2003 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
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

Funds. Please feel free to contact us with questions or comments.

                   STANDISH MELLON INVESTMENT GRADE BOND FUND

                       Management Discussion and Analysis
                                  December 2003

The market environment improved dramatically over the course of the year. As we
began 2003, the war with Iraq, weak job growth and deflation concerns posed
considerable risks to economic growth. However, second half GDP was boosted by
prompt military action, tax cuts and another mortgage refinancing boom. By
mid-year, a pick up in growth pushed interest rates higher. However, the Federal
Reserve has tempered the upward pressure on bond yields by emphasizing their
focus on inflation over growth. With core inflation dipping to 1.1%
year-over-year, and job growth still sluggish, the Fed has little reason to
raise interest rates in the near term.

Over the past year, Treasury Inflation Protected Securities (TIPS) and
investment grade corporate bonds solidly outperformed other fixed income
sectors. As the previous year's negative events faded from the headlines and
corporate profits surged, credit spreads narrowed significantly. Similarly, as
the economic picture improved, inflation expectations rose and TIPS
outperformed. In comparison, the relative performance of mortgages and agencies
lagged. The mortgage market suffered amid sharp interest rate moves which
resulted in significant hedging costs and diminished returns. The agency sector
also suffered as Freddie Mac's accounting issues surfaced and regulatory
oversight came under harsh scrutiny.

For the first half of the year, the Fund was defensively postured with an
underweight in corporate bonds and overweight positions in mortgages, asset
backed securities and commercial mortgages. The Fund's conservative stance was a
drag on performance as we saw stellar performance in corporate bonds relative to
other sectors. However, as the economy's momentum picked up around mid-year, we
increased the allocation to credit which helped performance in the second half.
Our underweight to agency bonds for the majority of the year strongly
contributed to performance. A sizable reduction to the mortgage position was
well-timed as we avoided July's massive underperformance when interest rates
backed up and durations extended sharply. Mortgage security selection was
particularly positive in the beginning of the year as we favored lower coupon
issues that benefited from very strong demand by banks. By the end of the year,
the Fund's returns, gross of fees, had picked up considerably and we concluded
the year just ahead of the benchmark.

Looking ahead, the prospects for economic growth in 2004 appear quite good.
Solid corporate profits should spur business spending and a weaker dollar should
support higher export activity. Inventory rebuilding should also boost GDP in
the first half. With strong productivity and lots of excess capacity, a low
inflation environment should persist. In this environment, the Fed will likely
hold interest rates unchanged for most of the year. The key investment themes
are building the Fund's yield advantage and a bulleted intermediate curve
position. Among the various spread sectors, we favor corporate bonds as we find
the fundamental improvement of credit quality remains


                                       3


solidly in place. Given a steep yield curve, we are more heavily weighted toward
intermediate bonds in the 2 to 5 year area. The Fund's overweight position in
commercial mortgage and asset backed securities emphasizes our intermediate
bias. The less-thanbenchmark weighting in mortgages also fits well with our
yield curve strategy as amortizing assets are less attractive than bullet
securities. Finally, we continue to find TIPS attractive as we expect a gradual
rise in inflation expectations given Fed policy will err on the accommodative
side in order to successfully reflate the economy.

As always, we look forward to serving you in the coming year.

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

Net investment income per share(1)                         $  0.63  $  0.83  $  1.17        $  0.78

(a)  The Fund has adopted the provisions of the revised AICPA Audit and
     Accounting Guide for Investment Companies effective January 1, 2001 and
     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to decrease net investment income per share by
     $0.004, increase net realized and unrealized gains and losses per share by
     $0.004 and decrease the ratio of net investment income to average net
     assets from 6.02% to 6.00%. Per share data and ratios/supplemental data for
     the periods prior to January 1, 2001 have not been restated to reflect this
     change in presentation.
(1)  Calculated based on average shares outstanding.
+    Computed on an annualized basis.
++   Not annualized.
+++  Total return would have been lower in the absence of expense waivers.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                   STANDISH MELLON INVESTMENT GRADE BOND FUND

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

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

     On June 21, 2003, by vote of the Trustees, the name of the Standish
     Investment Grade Bond Fund was changed to Standish Mellon Investment Grade
     Bond Fund. In addition, the Declaration of Trust was amended to change the
     name of the Trust from Standish, Ayer & Wood Investment Trust to Mellon
     Institutional Funds Investment Trust. The name changes became effective
     July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

     B. REPURCHASE AGREEMENTS

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

     C. SECURITIES TRANSACTIONS AND INCOME

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

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

     D. DISTRIBUTIONS TO SHAREHOLDERS

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

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

     E. EXPENSES

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

     F. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
     Financial Corporation, for overall investment advisory and administrative
     services and general office facilities, is paid monthly at the annual rate
     of 0.40% of the Fund's average daily net assets. Standish Mellon
     voluntarily agreed to limit total Fund operating expenses (excluding
     brokerage commissions, taxes and extraordinary expenses) to 0.40% of the
     Fund's average daily net assets for the year ended December 31, 2003.
     Pursuant to this agreement, for the year ended December 31, 2003, Standish
     Mellon voluntarily did not impose $222,267 of its investment advisory fee.
     This agreement is voluntary and temporary and may be discontinued or
     revised by Standish Mellon at any time.

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

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

     At December 31, 2003, two shareholders held of record approximately 67% and
     14% of the total outstanding shares of the Fund. Investment activity of
     these shareholders could have a material impact on the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes all of its taxable income for its fiscal year.
     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 December 31, 2003 were as follows:

       Unrealized appreciation                                       $1,331,784
       Unrealized depreciation                                         (241,074)
                                                                     ----------

       Cost for federal income tax purposes                          $71,702,647

(6)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

     A summary of the written put options for the year ended December 31, 2003
     is as follows:

     At December 31, 2003, the Fund had segregated sufficient securities for
     open written options contracts.

     INTEREST RATE FLOORS

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

     At December 31, 2003, the Fund held no open interest rate floor agreements.

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

     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 December 31, 2003, the Fund held the following financials futures
     contracts:



                                                                    UNDERLYING FACE

     SWAP AGREEMENTS

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

                                                the total return of The Lehman

(7)  SECURITY LENDING:

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

     The Fund loaned securities during the year ended December 31, 2003
     resulting in security lending income. At December 31, 2003, the Fund had no
     securities on loan.

(8)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

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

     See the Schedule of Investments for outstanding delayed delivery contracts.

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon Investment Grade 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 Mellon
     Institutional Funds Investment Trust: Standish Mellon Investment Grade Bond
     Fund (formerly, Standish Investment Grade Bond Fund) (the "Fund") at
     December 31, 2003, 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 auditing standards generally
     accepted in the United States of America, which 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 December 31, 2003 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
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

Funds. Please feel free to contact us with questions or comments.

               STANDISH MELLON OPPORTUNISTIC HIGH YIELD BOND FUND

                       Management Discussion and Analysis
                                  December 2003

Performance

Just when it looked like the high yield market might settle down and glide
through the last month of the year, bond prices moved sharply higher during
December. December's monthly return was one of seven that exceeded 2% and high
yield finished with its best year since 1991. For the month the Standish Mellon
Opportunistic High Yield Fund returned 2.32%, modestly topping the 2.26% return
of the benchmark Lehman High Yield Index. The Fund had a total return in 2003 of
21.77%, which underperformed the Index mark of 28.97%. The high yield asset
class was the star of the fixed income market in 2003 as it significantly
outperformed most competitors, with Emerging Markets coming the closest at
26.93%. High yield outperformed the Lehman Aggregate Index (+4.1% 2003 total
return) by almost 23%.

From a quality perspective the return pattern for December mirrored the one that
held steady throughout the year: outperformance by the most speculative
securities. In December, CCC and Ca thru D rated securities returned 3.43% and
3.58% respectively. The B sector was next at 2.34% and BB's followed along at
1.54%. The story for the year, as we have related repeatedly, was the same but
on a much bigger scale. Lehman's Ca and defaulted bond subindex returned 86.29%
for the year while CCC's were next in line with a stunning +60.23%. The more
mainstream rating sectors had strong but much lower returns with B's gaining
26.59% and BB's rising 19.95%. Two of the outcomes from all this performance are
worth noting: the average dollar price of bonds in the Index is nearly 103
(CCC's alone are over 94) and CCC and lower rated bonds represent 18%-20% of the
market value of every broad high yield index.

On an industry basis December's outperforming sectors were led by a price
recovery in steel (+9.21%) and late in the month gains from the cable sector
(+4.28%). Again, the standout under-performing sector (a small component of the
total market at 0.7%) was textile/apparel, which fell a further 2.09% during the
month largely due to further price deterioration in Levi's securities. For the
year, apparel/textile is the only sector reporting a negative total return at
- -3.85%. Interestingly, only one other market sector has a YTD total return of
less than 10%: steel at +9.91%, almost all of which came in December. Combined,
these two laggard sectors represent less than 1.5% of the high yield universe.

With lower quality bonds dominating returns in 2003, it follows that the
industry classifications containing a concentration of those lower
priced/higher-yielding securities would provide the bulk of outperformance. The
top performing industries were electric utilities (+52.29%), telecommunications
(+46.77%), cable TV (+46.03%, a large share from Charter) and technology
(+41.44%). All of these industries represent large components of the high yield
index universe, with each exceeding a 3.5% share, and in total they represent
about 28% of the asset class's market value.


                                       3


Despite the huge returns in these four industries, fundamental credit
improvement within them was not universally observed. A return of capital market
access did solve almost all near term liquidity problems for many companies. But
notable large issuers such as Calpine, Charter Communications, Level Three
Communications, Lucent Technologies and Qwest Communications still face enormous
competitive threats and business execution issues. We have had limited or zero
exposure to these companies.

In examining the performance of the Standish Mellon Opportunistic High Yield
Fund against the benchmark, the major discrepancy was caused by the huge returns
from credit situations that were stressed and at low dollar prices starting the
year. Our higher-quality strategy and concentration on cash flow generating B
and BB credits was not a recipe for outperformance in 2003. Although we avoided
what few credit problems did occur, the sectors that did poorly were not
material parts of the universe. Also, positive performance opportunities from
security selection standpoint were limited to a fairly small list of industries:
of the 37 industry classifications defined in the Merrill Lynch Master Index
only six had returns above the overall return of the Index. Of the four big
outperforming sectors listed above, the Fund's portfolio had a large overweight
in the utility area; particularly in the asset-value rich pipeline operating
subsidiaries. Our exposure to the other three was limited primarily due to
fundamental credit concerns and, in the case of Qwest, a lack of audited
financial statements upon which to base a credit opinion.

Market Environment

The market commentary surrounding the huge cash flows in the market remains the
same and is substantially repeated below. High yield mutual fund flows continued
to be positive as over $1 billion was allocated in December thus increasing 2003
inflows to $27 billion. As a back of the envelope demonstration of the technical
strength of the asset class, consider that in 2003 the high yield market had
approximately $121 billion in new issuance. A bit less than half of that total
was in the form of refinancings and as such does not represent net new issuance.
Against the roughly $70 billion in net new issuance, sources of cash for the
market include about $50 billion in high yield coupon income, the aforementioned
$27 billion in mutual fund flows plus all institutional, hedge fund and
insurance company commitments not flowing to reporting mutual funds.

Wall Street of course has a ready answer for this situation: more high yield
paper. As the search for potential issuers widens and portfolio managers
continue to search for any new opportunity with yield, the quality of the new
issuance has declined precipitously. The average ratings of new deals have
fallen and CCC new issues have become a regular occurrence. Other anecdotal
signs of quality decline include: the return of zero-coupon issues, new deals of
less than $100 million, paper from industries such as sub-prime finance,
shipping, European cable and CLECs all of which were effectively banished from
the high yield primary market due to horrific default rates.


                                       4


Portfolio Strategy and Outlook

Seemingly ever-higher high yield bond prices continue to be supported by high
levels of investor liquidity and improving trends in defaults and ratings
actions. The burning questions now are: what is likely to change this situation
and when might the change occur? Our feeling is that although spreads on high
yield securities have declined, the asset class continues to offer attractive
return opportunities relative to other higher quality fixed income options,
particularly if the default experience continues to decline. High yield
investments to be avoided, therefore, are ones that may experience credit
stress. That statement sounds obvious, but the behavior of the market is just
the opposite -- there is a huge thirst for risk and yield, and performance in
2003 was dominated by the price recovery of the most stressed situations. We
intend to invest based on sensible risk reward from a credit standpoint.

We believe that the credit stress associated with the risky crop of issues
priced in the past six months will occur sometime in the next 18 to 36 months.
Also, companies that were facing liquidity and capital market access
difficulties were bailed out in 2003 but many of those companies also have
significant business challenges that have not been addressed or improved. When
investors begin to fear the possibility that those business issues will not be
solved those credits will suffer. The other timing consideration that will
impact the market will occur when high yield buyers feel that, despite excess
portfolio cash, it is time to sell the new issues from weak credits that were
purchased in a hot market. That exercise will be the high yield portfolio
management guessing game in 2004 for those who are currently aggressively
invested.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                 STANDISH MELLON OPPORTUNISTIC HIGH YIELD 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 Opportunistic High Yield Fund (the "Fund") is a separate
     non-diversified investment series of the Trust.

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

     On June 21, 2003, by vote of the Trustees, the name of the Standish
     Opportunistic High Yield Fund was changed to Standish Mellon Opportunistic
     High Yield Fund. In addition, the Declaration of Trust was amended to
     change the name of the Trust from Standish, Ayer & Wood Investment Trust to
     Mellon Institutional Funds Investment Trust. The name changes became
     effective July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

     B. REPURCHASE AGREEMENTS

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

     C. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of the trade date. Interest income
     is determined on the basis of interest accrued, adjusted for accretion of
     discount or amortization of premium using the yield-to-maturity method on
     long-term debt securities. Dividend income is recorded on the ex-dividend
     date. Realized gains and losses from securities sold are recorded on the
     identified cost basis. The Fund does not isolate that portion of the
     results of operations resulting from

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                 STANDISH MELLON OPPORTUNISTIC HIGH YIELD FUND

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

     changes in foreign exchange rates on investments from the fluctuations
     arising from changes in market prices of securities held. Such fluctuations
     are included with the net realized and unrealized gain or loss from
     investments. Net realized gains and losses on foreign currency transactions
     represent gains and losses on disposition of foreign currencies and forward
     foreign currency exchange contracts, currency gains and losses realized
     between the trade and settlement dates on securities transactions, and the
     difference between the amount of investment income and foreign withholding
     taxes recorded on the Fund's books and the U.S. dollar equivalent amounts
     usually received or paid.

     D. FOREIGN CURRENCY TRANSACTIONS

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

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

     E. DISTRIBUTIONS TO SHAREHOLDERS

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

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

     F. EXPENSES

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

     G. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

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

     general office facilities, is paid monthly at the annual rate of 0.40% of
     the Fund's average daily net assets. Standish Mellon voluntarily agreed to
     limit total Fund operating expenses (excluding brokerage commissions, taxes
     and extraordinary expenses) to 0.10% of the Fund's average daily net assets
     for the year ended December 31, 2003. Pursuant to this agreement, for the
     year ended December 31, 2003, Standish Mellon voluntarily did not impose
     $148,664 of its investment advisory fee and reimbursed the Fund for
     $151,462 of its operating expenses. This agreement is voluntary and
     temporary and may be discontinued or revised by Standish Mellon at any
     time.

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

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended December 31, 2003 were $46,891,637 and
     $46,666,730, respectively. For the year ended December 31, 2003, the Fund
     did not purchase or sell any long-term U.S. government securities.

(4)  SHARES OF BENEFICIAL INTEREST:

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



                                                                  YEAR ENDED            YEAR ENDED

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


     At December 31, 2003, five shareholders held of record approximately 21%,
     13%, 11%, 11% and 11% of the total outstanding shares of the Fund. All of
     the Fund's shares are beneficially owned by fiduciary accounts over which
     Standish Mellon and its affiliates have either sole or joint investment
     discretion. Investment activity of these shareholders could have a material
     impact on the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes 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 December 31, 2003 were as follows:

         Unrealized appreciation                                    $ 3,269,762
         Unrealized depreciation                                       (486,693)

         Cost for federal income tax purposes                       $39,069,661

     At December 31, 2003, the Fund, for federal income tax purposes had 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. The capital loss carryovers are
     $11,205,658 and $7,303,547 which expire on December 31, 2009 and 2010,
     respectively.

     The tax character of distributions paid during the fiscal year ended
     December 31, 2003, was as follows:

                                                                       AMOUNT

(6)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

     The Fund entered into no such transactions during the year ended December
     31, 2003.

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     At December 31, 2003, the Fund held the following forward foreign currency
     or cross currency exchange contracts:

     SWAP AGREEMENTS

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

     FUTURES CONTRACTS

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

     The Fund entered into no such transactions during the year ended December
     31, 2003.

(7)  SECURITY LENDING:

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

     The Fund loaned securities during theyear ended December 31, 2003 resulting
     in security lending income. At December 31, 2003 the Fund had no securities
     on loan.

(8)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

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

     The Fund entered into no such transactions during the year ended December
     31, 2003.

(9)  CONCENTRATION OF RISK:

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

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon Opportunistic High Yield 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 Mellon
     Institutional Funds Investment Trust: Standish Mellon Opportunistic High
     Yield Fund (fomerly, Standish Opportunistic High Yield Fund) (the "Fund")
     at December 31, 2003, and the results of its operations, the changes in its
     net assets and the financial highlights for 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 auditing standards generally
     accepted in the United States of America, which 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 December 31, 2003 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
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

Funds. Please feel free to contact us with questions or comments.


Sincerely,

                      STANDISH MELLON HIGH YIELD BOND FUND

                       Management Discussion and Analysis
                                  December 2003

Performance

Just when it looked like the high yield market might settle down and glide
through the last month of the year, bond prices moved sharply higher during
December. December's monthly return was one of seven that exceeded 2% and high
yield finished with its best year since 1991. For the month the Standish Mellon
High Yield Fund returned 2.28% modestly topping the 2.26% return of the
benchmark Lehman High Yield Index. The Fund had a total return in 2003 of
21.76%, which underperformed the Index mark of 28.97%. The high yield asset
class was the star of the fixed income market in 2003 as it significantly
outperformed most competitors, with Emerging Markets coming the closest at
26.93%. High yield outperformed the Lehman Aggregate Index (+4.1% 2003 total
return) by almost 23%.

From a quality perspective the return pattern for December mirrored the one that
held steady throughout the year: outperformance by the most speculative
securities. In December, CCC and Ca thru D rated securities returned 3.43% and
3.58% respectively. The B sector was next at 2.34% and BB's followed along at
1.54%. The story for the year, as we have related repeatedly, was the same but
on a much bigger scale. Lehman's Ca and defaulted bond sub-index returned 86.29%
for the year while CCC's were next in line with a stunning +60.23%. The more
mainstream rating sectors had strong but much lower returns with B's gaining
26.59% and BB's rising 19.95%. Two of the outcomes from all this performance are
worth noting: the average dollar price of bonds in the Index is nearly 103
(CCC's alone are over 94) and CCC and lower rated bonds represent 18%20% of the
market value of every broad high yield index.

On an industry basis December's outperforming sectors were led by a price
recovery in steel (+9.21%) and late in the month gains from the cable sector
(+4.28%). Again, the standout under-performing sector (a small component of the
total market at 0.7%) was textile/apparel, which fell a further 2.09% during the
month largely due to further price deterioration in Levi's securities. For the
year, apparel/textile is the only sector reporting a negative total return at
- -3.85%. Interestingly, only one other market sector has a YTD total return of
less than 10%: steel at +9.91%, almost all of which came in December. Combined,
these two laggard sectors represent less than 1.5% of the high yield universe.

With lower quality bonds dominating returns in 2003, it follows that the
industry classifications containing a concentration of those lower
priced/higher-yielding securities would provide the bulk of outperformance. The
top performing industries were electric utilities (+52.29%), telecommunications
(+46.77%), cable TV (+46.03%, a large share from Charter) and technology
(+41.44%). All of these industries represent large components of the high yield
index universe, with each exceeding a 3.5% share, and in total they represent
about 28% of the asset class's market value.


                                       3


Despite the huge returns in these four industries, fundamental credit
improvement within them was not universally observed. A return of capital market
access did solve almost all near term liquidity problems for many companies. But
notable large issuers such as Calpine, Charter Communications, Level Three
Communications, Lucent Technologies and Qwest Communications still face enormous
competitive threats and business execution issues. We have had limited or zero
exposure to these companies.

In examining the performance of the Standish Mellon High Yield Fund against the
benchmark, the major discrepancy was caused by the huge returns from credit
situations that were stressed and at low dollar prices starting the year. Our
higher-quality strategy and concentration on cash flow generating B and BB
credits was not a recipe for outperformance in 2003. Although we avoided what
few credit problems did occur, the sectors that did poorly were not material
parts of the universe. Also, positive performance opportunities from security
selection standpoint were limited to a fairly small list of industries: of the
37 industry classifications defined in the Merrill Lynch Master Index only six
had returns above the overall return of the Index. Of the four big outperforming
sectors listed above, the Fund's portfolio had a large overweight in the utility
area; particularly in the asset-value rich pipeline operating subsidiaries. Our
exposure to the other three was limited primarily due to fundamental credit
concerns and, in the case of Qwest, a lack of audited financial statements upon
which to base a credit opinion.

Market Environment

The market commentary surrounding the huge cash flows in the market remains the
same and is substantially repeated below. High yield mutual fund flows continued
to be positive as over $1 billion was allocated in December thus increasing 2003
inflows to $27 billion. As a back of the envelope demonstration of the technical
strength of the asset class, consider that in 2003 the high yield market had
approximately $121 billion in new issuance. A bit less than half of that total
was in the form of refinancings and as such does not represent net new issuance.
Against the roughly $70 billion in net new issuance, sources of cash for the
market include about $50 billion in high yield coupon income, the aforementioned
$27 billion in mutual fund flows plus all institutional, hedge fund and
insurance company commitments not flowing to reporting mutual funds.

Wall Street of course has a ready answer for this situation: more high yield
paper. As the search for potential issuers widens and portfolio managers
continue to search for any new opportunity with yield, the quality of the new
issuance has declined precipitously. The average ratings of new deals have
fallen and CCC new issues have become a regular occurrence. Other anecdotal
signs of quality decline include: the return of zero-coupon issues, new deals of
less than $100 million, paper from industries such as sub-prime finance,
shipping, European cable and CLECs all of which were effectively banished from
the high yield primary market due to horrific default rates.


                                       4


Portfolio Strategy and Outlook

Seemingly ever-higher high yield bond prices continue to be supported by high
levels of investor liquidity and improving trends in defaults and ratings
actions. The burning questions now are: what is likely to change this situation
and when might the change occur? Our feeling is that although spreads on high
yield securities have declined, the asset class continues to offer attractive
return opportunities relative to other higher quality fixed income options,
particularly if the default experience continues to decline. High yield
investments to be avoided, therefore, are ones that may experience credit
stress. That statement sounds obvious, but the behavior of the market is just
the opposite -there is a huge thirst for risk and yield, and performance in 2003
was dominated by the price recovery of the most stressed situations. We intend
to invest based on sensible risk reward from a credit standpoint.

We believe that the credit stress associated with the risky crop of issues
priced in the past six months will occur sometime in the next 18 to 36 months.
Also, companies that were facing liquidity and capital market access
difficulties were bailed out in 2003 but many of those companies also have
significant business challenges that have not been addressed or improved. When
investors begin to fear the possibility that those business issues will not be
solved those credits will suffer. The other timing consideration that will
impact the market will occur when high yield buyers feel that, despite excess
portfolio cash, it is time to sell the new issues from weak credits that were
purchased in a hot market. That exercise will be the high yield portfolio

     discount on all debt securities on an effective yield basis. The effect of
     this change for the year ended December 31, 2001 was to decrease net
     investment income per share by $0.05, increase net realized and unrealized
     gains and losses per share by $0.05 and decrease the ratio of net
     investment income to average net assets from 9.20% to 8.86%. Per share data

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                      STANDISH MELLON HIGH YIELD 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 High Yield Bond Fund (the "Fund") is a separate diversified
     investment series of the Trust.

     The objective of the Fund is to maximize total return, consisting primarily
     of a high level of income. The Fund seeks to achieve its objective by
     investing all of its investable assets in an interest of the Standish
     Mellon High Yield Bond Portfolio (the "Portfolio"), a subtrust of the
     Mellon Institutional Funds Master Portfolio ( the "Portfolio Trust"), which
     is organized as a New York trust and which has the same investment
     objective as the Fund. The Portfolio seeks to achieve its objective by
     investing, under normal circumstances, at least 80% of net assets in fixed
     income securities issued by U.S. and foreign governments, companies and
     banks, as well as tax-exempt securities, preferred stocks and warrants. The
     value of the Fund's investment in the Portfolio reflects the Fund's
     proportionate interest in the net assets of the Portfolio (approximately
     100% at December 31, 2003). The performance of the Fund is directly
     affected by the performance of the Portfolio. The financial statements of
     the Portfolio are included elsewhere in this report and should be read in
     conjunction with the Fund's financial statements.

     On June 21, 2003, by vote of the Trustees, the name of the Standish High
     Yield Bond Fund was changed to Standish Mellon High Yield Bond Fund. In
     addition, the Declaration of Trust was amended to change the name of the
     Trust from Standish, Ayer & Wood Investment Trust to Mellon Institutional
     Funds Investment Trust. The name changes became effective July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. DISTRIBUTIONS TO SHAREHOLDERS

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

                                       11


                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                      STANDISH MELLON HIGH YIELD BOND FUND

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

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

     D. EXPENSES

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

     E. COMMITMENT AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary of Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report. Standish Mellon voluntarily agreed to
     limit the total operating expenses of the Fund and its pro rata share of
     the Portfolio expenses (excluding commissions, taxes and extraordinary
     expenses) to 0.50% of the Fund's average daily net assets. This agreement
     is voluntary and temporary and may be discontinued or revised by Standish
     Mellon at any time. Pursuant to this agreement, for the year ended December
     31, 2003, Standish Mellon voluntarily reimbursed the Fund for $78,353 of
     its operating expenses.

     Effective January 28, 2003, the Fund began imposing a redemption fee of 2%
     of the net asset value of the shares, with certain exceptions, which are
     redeemed or exchanged less than 90 days from the day of their purchase. The
     redemption fee is paid directly to the Fund, and is designed to offset
     brokerage commissions, market impact, and other costs associated with
     short-term trading. The fee does not apply to shares that were acquired
     through reinvestment of distributions. For the period ended December 31,
     2003, the Fund received $1,380 in redemption fees.

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

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended December 31, 2003 aggregated $13,400,767 and $10,633,762,
     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:



                                                                  YEAR ENDED            YEAR ENDED

     At December 31, 2003, one shareholder held of record approximately 57% of
     the total outstanding shares of the Fund. Investment activity of this
     shareholder 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.

(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 December 31, 2003, the components of distributable earnings on a tax
     basis were as follows:

                                                                      AMOUNT
                                                                   ------------
         Accumulated losses                                        $(11,733,921)

     At December 31, 2003, 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

           4,197,096     12/31/2010

     The fund elected to defer to its fiscal year ending December 31, 2004
     $270,741 of losses recognized during the period November 1, 2003 to
     December 31, 2003.

     The tax character of distributions paid during the fiscal year ended
     December 31, 2003, was as follows:

         Distributions paid from:
           Ordinary income                                            $4,091,517

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Investment Trust and
     Shareholders of Standish Mellon High Yield Bond 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 Mellon Institutional Funds Investment Trust: Standish
     Mellon High Yield Bond Fund (formerly, Standish High Yield Bond Fund) (the
     "Fund") at December 31, 2003, 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
     auditing standards generally accepted in the United States of America,
     which 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 correspondence with the custodian,
     provide a reasonable basis for our opinion.

     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to decrease the ratio of net investment income to
     average net assets from 9.20% to 8.87%. Ratios for the periods prior to
     January 1, 2001 have not been restated to reflect this change in

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

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

     At December 31, 2003, there was one fund, Standish Mellon High Yield Bond
     Fund (the "Fund"), invested in the Portfolio. The value of the Fund's
     investment in the Portfolio reflects the Fund's proportionate interest in
     the net assets of the Portfolio. The Fund's proportionate interest at
     December 31, 2003 was approximately 100%.

     On June 21, 2003, by vote of the Trustees, the name of the Standish High
     Yield Bond Portfolio was changed to Standish Mellon High Yield Bond
     Portfolio. In addition, the Declaration of Trust was amended to change the
     name of the Portfolio Trust from Standish, Ayer & Wood Master Portfolio to
     Mellon Institutional Funds Master Portfolio. The name changes became
     effective July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

     B. REPURCHASE AGREEMENTS

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

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

     C. SECURITIES TRANSACTIONS AND INCOME

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

     D. INCOME TAXES

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

     E. FOREIGN CURRENCY TRANSACTIONS

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

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

     F. EXPENSES

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

     G. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon") for overall investment advisory and
     administrative services is paid monthly at the annual rate of 0.50% of the
     Portfolio's

(5)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

     Premiums received from writing options which expire are treated as realized
     gains. Premiums received from writing options which are exercised or are
     closed are added to or offset against the proceeds or amount paid on the
     transaction to determine the realized gain or loss. Realized gains and
     losses on purchased options are included in realized gains and losses on
     investment securities, except purchased options on foreign currency which
     are included in realized gains and

     losses on foreign currency transactions. If a put option written by the
     Portfolio is exercised, the premium reduces the cost basis of the
     securities purchased by the Portfolio. The Portfolio, as a writer of an
     option, has no control over whether the underlying securities may be sold
     (call) or purchased (put) and as a result bears the market risk of an
     unfavorable change in the price of the security underlying the written
     option.

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

     A summary of the written put options for the year ended December 31, 2003
     is as follows:

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     At December 31, 2003, the Portfolio held the following forward foreign
     currency exchange contracts:

     SWAP AGREEMENTS

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

(6)  SECURITY LENDING:

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

     The Portfolio loaned securities during the year ended December 31, 2003
     resulting in security lending income. At December 31, 2003, the Portfolio
     had no securities on loan.

(7)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

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

     At December 31, 2003, the Portfolio did not have any delayed delivery
     transactions.

(8)  CONCENTRATION OF RISK:

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

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

(9)  LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
     Trust are parties to a committed line of credit facility with Investors
     Bank and Trust Co., which enables each portfolio/fund to borrow, in the
     aggregate, up to $35 million. Interest is charged to each participating
     portfolio/fund based on its borrowings at a rate equal to the Federal Funds
     effective rate plus 1/2 of 1%. In addition, a commitment fee, computed at
     an annual rate of .065 of 1% on the daily unused portion of the facility,
     is allocated ratably among the participating portfolios/funds at the end of
     each quarter.

     For the year ended December 31, 2003, the expense related to the commitment
     fee was $1,558 for the Portfolio.

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

     For the year ended December 31, 2003, the expense related to the commitment
     fee was $378 for the Portfolio.

     During the year ended December 31, 2003, the Portfolio had no borrowings
     under the credit facilities.

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Master Portfolio and the
     Investors of Standish Mellon High Yield Bond 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 Mellon
     Institutional Funds Master Portfolio: Standish Mellon High Yield Bond
     Portfolio (formerly, Standish High Yield Bond Portfolio) (the "Portfolio"),
     at December 31, 2003, 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 auditing standards generally
     accepted in the United States of America, which 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 December 31, 2003, 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
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

Funds. Please feel free to contact us with questions or comments.

                    STANDISH MELLON GLOBAL FIXED INCOME FUND

                       Management Discussion and Analysis
                                  December 2003

Global bond markets produced modest, positive returns in 2003. The Standish
Mellon Global Fixed Income Fund returned 6.38% for the year, after all expenses,
compared to our benchmarks of 2.09% for the JP Morgan Hedged Global Government
Bond Index, and 3.11% for the Lehman Global Aggregate Hedged Index.

Global bond market returns had two distinct phases during 2003 that were driven
by a series of economic, financial and geopolitical developments. During the
first half of the year, bond markets were generally strong, led by the U.S.
market. The global economy was weak, although there were signs of recovery, and
financial market participants were concerned about the possibility of deflation,
particularly in the U.S. The Iraq war and concern about North Korea's nuclear
weapons program further weighed on confidence and the growth outlook. In
addition, financial market scandals caused some investors to abandon riskier
assets such as stocks. Bonds looked like a safe bet.

During the second half of the year, global growth accelerated and confidence
returned to financial markets. The heavy fighting was over in Iraq and progress
was being made on the Korean Peninsula. The Federal Reserve had lowered rates to
their lowest level since 1958 and the combination of low interest rates and
fiscal stimulus was taking hold. The health of global companies was improving
with increasing profits and declining credit spreads. Equities were rallying
globally as were emerging market stocks and bonds. As the fear of deflation
faded, bond yields rose dramatically from the mid-year lows.

The range of returns in hedged terms for government bond markets as measured by
the JP Morgan Government Bond Indices was modest for the year with only 514 b.p.
separating the best market Canada (+4.52%) from the worst, Australia (-0.62%).
The U.S. component of the index returned 2.44% while European markets returned
2.80% and Japan only 36 b.p. Although government bond returns were modest in
2003, corporate and emerging market bonds performed quite well. The higher
yielding segments of the bond market produced the best returns with high yield
corporate bonds and emerging market bond indices recording returns in excess of
20%. The U.S. dollar fell during the year as the mix of loose fiscal and
monetary policy and the large current account deficit made the currency
unattractive to global investors.

During this period of U.S. dollar weakness, the Fund has not been able to make
regular distributions of investment income. This is due to our policy of hedging
most of our currency exposures back to U.S. dollars. Although this policy
results in less volatility in total return over time than if the portfolio were
unhedged, currency volatility can have a significant effect on the Fund's
investment income. In periods when the dollar declines as it has over the past
two years, the losses from the currency hedging activity offset the investment
income of the portfolio. Conversely, when the dollar appreciates, our


                                       3


currency hedging activity typically generates gains that enhance the investment
income of the Fund. Another way to view this is that much of the Fund's reported
total return -which has been very strong compared to the Index -- is classified
as capital appreciation within the portfolio.

The Fund outperformed its benchmarks during the year. Our position in investment
grade and high yield corporate bonds and emerging market securities was the
largest positive contributor relative to our benchmarks. Our country selection
was also positive as we were overweighted European markets and zero weighted in
Japan. Our currency exposure was positive for the year relative to the benchmark
as we had established positions in the euro and the Australian, New Zealand and
Canadian dollars relative to the U.S. dollar and all those positions contributed
positively in 2003.

Our outlook for 2004 is favorable for global bonds. We believe that the
performance of global economies will be mixed in the coming year with the U.S.
growing above trend, Japan on trend and Europe below. Government bond yields in
the U.S. will be biased upwards but opportunities for value-added can be found
in European bonds as the European Central Bank is likely to lag any moves by the
Fed to increase interest rates. Non-government sectors such as corporate and
emerging bonds offer value in 2004 as credit quality improves. However, the
excess returns are likely to be more modest than in 2003.

We appreciate your continued support and look forward to working on your behalf
over the next year.


/s/ W. Charles Cook

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

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

(a)  Through its investment in the Portfolio, the Fund has adopted the
     provisions of the revised AICPA Audit and Accounting Guide for Investment
     Companies effective January 1, 2001 and began amortizing premium and
     discount on all debt securities on an effective yield basis. The effect of
     this change for the year ended December 31, 2001 was to decrease net
     investment income per share by $0.007, to increase net realized and
     unrealized gains and losses per share by $0.007 and decrease the ratio of
     net investment income to average net assets from 4.50% to 4.46%. Per share
     data and ratios/supplemental data for periods prior to January 1, 2001 have
     not been restated to reflect this change in presentation.
(1)  Calculated based on average shares outstanding.
(2)  The amount shown for a share outstanding does not correspond with the
     aggregate net realized and unrealized gain/loss for the period due to the
     timing of purchases and redemptions of Fund shares in relation to the
     fluctuating market values of the Fund.
+    Total return would have been lower in the absence of expense waivers.

                         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 Global Fixed Income Fund (the "Fund") is a separate
     non-diversified investment series of the Trust.

     The objective of the Fund is to maximize total return while realizing a
     market level of income consistent with preserving principal and liquidity.
     The Fund seeks to achieve its objective by investing all of its investable
     assets in an interest of Standish Mellon Global Fixed Income Portfolio (the
     "Portfolio"), a subtrust of the Mellon Institutional Funds Master Portfolio
     (the "Portfolio Trust"), which is organized as a New York trust and which
     has the same investment objective as the Fund. The Portfolio seeks to
     achieve its investment objective by investing, under normal circumstances,
     at least 80% of its net assets in U.S. and non-U.S. dollar denominated
     fixed income securities of U.S. and foreign governments and companies
     located in the U.S. and various countries, including emerging markets. The
     value of the Fund's investment in the Portfolio reflects the Fund's
     proportionate interest in the net assets of the Portfolio (approximately
     100% at December 31, 2003). The performance of the Fund is directly
     affected by the performance of the Portfolio. The financial statements of
     the Portfolio are included elsewhere in this report and should be read in
     conjunction with the Fund's financial statements.

     On June 21, 2003, by vote of the Trustees, the name of the Standish Global
     Fixed Income Fund was changed to Standish Mellon Global Fixed Income Fund.
     In addition, the Declaration of Trust was amended to change the name of the
     Trust from Standish, Ayer & Wood Investment Trust to Mellon Institutional
     Funds Investment Trust. The name changes became effective July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. In determining the amounts of its dividends,
     the Fund will take into account its share of the income, gains or losses,
     expenses, and any other tax items of the Portfolio. Distributions to
     shareholders are recorded on ex-dividend date. Dividends from net
     investment income and distributions from capital gains, if any, are
     reinvested in additional shares of the Fund unless a shareholder elects to
     receive them in cash. Income and capital gain distributions are determined
     in accordance with income tax regulations which may differ from accounting
     principles generally accepted in the United

                                       10

     States of America. These differences, which may result in distribution
     reclassifications, are primarily due to differing treatments for foreign
     currency transactions, options, futures, amortization and/or accretion of
     premiums and discounts on certain securities, capital loss carryforwards
     and losses deferred due to wash sales.

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

     D. EXPENSES

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

     E. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary of Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report. Standish Mellon voluntarily agreed to
     limit the total operating expenses of the Fund and its pro rata share of
     the Portfolio expenses (excluding commissions, taxes and extraordinary
     expenses) to 0.65% of the Fund's average daily net assets for the year
     ended December 31, 2003. Pursuant to this agreement, for the year ended
     December 31, 2003, Standish Mellon voluntarily reimbursed the Fund for
     $85,583 of its operating expenses. This agreement is voluntary and
     temporary and may be discontinued or revised by Standish Mellon at any
     time.

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

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended December 31, 2003, aggregated $10,566,938 and $31,376,444,
     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:



                                                                  YEAR ENDED            YEAR ENDED

     At December 31, 2003, four shareholders held of record approximately 32%,
     19%, 15% and 14% of the total outstanding shares of the Fund, respectively.
     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.

(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 December 31, 2003, the components of distributable earnings on a tax
     basis were as follows:

                                                                     AMOUNT
                                                                  ------------
         Accumulated losses                                       $(31,409,647)

     At December 31, 2003, 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
         ------------  ---------------
         $ 6,326,146     12/31/2007

           3,621,061     12/31/2010

     The fund elected to defer to its fiscal year ending December 31, 2004
     $5,952,909 of losses recognized during the period November 1, 2003 to
     December 31, 2003.

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Investment Trust and
     Shareholders of Standish Mellon Global Fixed Income 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 Mellon Institutional Funds Investment Trust: Standish
     Mellon Global Fixed Income Fund (formerly, Standish Global Fixed Income
     Fund) (the "Fund") at December 31, 2003, 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
     auditing standards generally accepted in the United States of America,
     which 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 correspondence with the custodian,
     provide a reasonable basis for our opinion.

(a)  The Portfolio has adopted the provisions of the revised AICPA Audit and
     Accounting Guide for Investment Companies effective January 1, 2001 and
     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to decrease the ratio of net investment income to
     average net assets from 4.53% to 4.49%. Ratios for the periods prior to
     January 1, 2001 have not been restated to reflect this change in
     presentation.
+    Total return for the Portfolio has been calculated based on the total
     return for the invested Fund, assuming all distributions were reinvested,
     and adjusted for the difference in expenses as set out in the notes to the
     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. Standish
     Mellon Global Fixed Income Portfolio (the "Portfolio") is a separate
     non-diversified investment series of the Portfolio Trust.

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

     At December 31, 2003 there was one fund, Standish Mellon Global Fixed
     Income Fund (the "Fund"), invested in the Portfolio. The value of the
     Fund's investment in the Portfolio reflects the Fund's proportionate
     interest in the net assets of the Portfolio. The Fund's proportionate
     interest at December 31, 2003 was approximately 100%.

     On June 21, 2003, by vote of the Trustees, the name of the Standish Global
     Fixed Income Portfolio was changed to Standish Mellon Global Fixed Income
     Portfolio. In addition, the Declaration of Trust was amended to change the
     name of the Portfolio Trust from Standish, Ayer & Wood Master Portfolio to
     Mellon Institutional Funds Master Portfolio. The name changes became
     effective July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

     B. REPURCHASE AGREEMENTS

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

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

     C. SECURITIES TRANSACTIONS AND INCOME

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

     D. INCOME TAXES

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

     E. FOREIGN CURRENCY TRANSACTIONS

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

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

     F. EXPENSES

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

     G. 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.

     H. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

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

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

(5)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

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

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

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     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 December 31, 2003, the Portfolio held no outstanding financial futures
     contracts.

     INTEREST RATE SWAP CONTRACTS

     Interest rate swaps involve the exchange by the Portfolio with another
     party of their respective commitments to pay or receive interest, e.g., an
     exchange of floating rate payments for fixed rate payments with respect to
     a notional amount of principal. Credit and market risk exist with respect
     to these instruments. If forecasts of interest rates and other market
     factors are incorrect, investment performance will be diminished compared
     to what performance would have been if these investment techniques were not
     used. Even if the forecasts are correct, there are risks that the positions
     may correlate imperfectly with the asset or liability being hedged, a
     liquid secondary market may not always exist, or a counterparty to a
     transaction may not perform. The Portfolio expects to enter into these
     transactions primarily for hedging purposes including, but not limited to,
     preserving a return or spread on a particular investment or portion of its
     portfolio, protecting against currency fluctuations, managing duration or
     protecting against an increase in the price of securities the Portfolio
     anticipates purchasing at a later date. Interest rate swaps are marked to
     market daily based upon quotations from market makers and the change, if
     any, is recorded as unrealized gain or loss. Payments made or received are
     included as part of interest income. Gains and losses are realized upon the
     expiration or closing of the swap contracts.

     The Portfolio entered into no such transactions during the year ended
     December 31, 2003.

(6)  SECURITY LENDING:

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

     The Portfolio loaned securities during the year ended December 31, 2003
     resulting in security lending income. At December 31, 2003, the Portfolio
     had no securities on loan.

(7)  DELAYED DELIVERY TRANSACTIONS:

     The Portfolio may purchase or sell securities on a when-issued, delayed
     delivery or forward commitment basis. Payment and delivery may take place a
     month or more after the date of the transactions. The price of the
     underlying securities

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

     and the date when the securities will be delivered and paid for are fixed
     at the time the transaction is negotiated. Income on the securities will
     not be earned until settlement date. The Portfolio instructs its custodian
     to segregate securities having value at least equal to the amount of the
     purchase commitment.

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

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

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

     See the Schedule of Investments for outstanding delayed delivery
     transactions.

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Master Portfolio and the
     Investors of Standish Mellon Global Fixed Income 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 Mellon
     Institutional Funds Master Portfolio: Standish Mellon Global Fixed Income
     Portfolio (formerly, Standish Global Fixed Income Portfolio) (the
     "Portfolio"), at December 31, 2003, 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
     auditing standards generally accepted in the United States of America,
     which 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
     December 31, 2003, 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
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

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

                 STANDISH MELLON INTERNATIONAL FIXED INCOME FUND

                       Management Discussion and Analysis
                                  December 2003

International bond markets produced modest, positive returns in 2003. The
Standish Mellon International Fixed Income Fund returned 4.89% for the year,
after all expenses, compared to 1.98% for our benchmark, the JP Morgan Hedged
Non-U.S. Government Bond Index.

Global bond market returns had two distinct phases during 2003 that were driven
by a series of economic, financial and geopolitical developments. During the
first half of the year, bond markets were generally strong, led by the U.S.
market. The global economy was weak, although there were signs of recovery, and
financial market participants were concerned about the possibility of deflation,
particularly in the U.S. The Iraq war and concern about North Korea's nuclear
weapons program further weighed on confidence and the growth outlook. In
addition, financial market scandals caused some investors to abandon riskier
assets such as stocks. Bonds looked like a safe bet.

During the second half of the year, global growth accelerated and confidence
returned to financial markets. The heavy fighting was over in Iraq and progress
was being made on the Korean Peninsula. The Federal Reserve had lowered rates to
their lowest level since 1958 and the combination of low interest rates and
fiscal stimulus was taking hold. The health of global companies was improving
with increasing profits and declining credit spreads. Equities were rallying
globally as were emerging market stocks and bonds. As the fear of deflation
faded, bond yields rose dramatically from the mid-year lows.

The range of returns in hedged terms for government bond markets as measured by
the JP Morgan Government Bond Indices was modest for the year with only 514 b.p.
separating the best market Canada (+4.52%) from the worst, Australia (-0.62%).
The U.S. component of the index returned 2.44% while European markets returned
2.80% and Japan only 36 b.p. Although government bond returns were modest in
2003, corporate and emerging market bonds performed quite well. The higher
yielding segments of the bond market produced the best returns with high yield
corporate bonds and emerging market bond indices recording returns in excess of
20%. The U.S. dollar fell during the year as the mix of loose fiscal and
monetary policy and the large current account deficit made the currency
unattractive to global investors.

During this period of U.S. dollar weakness, the Fund has not been able to make
regular distributions of investment income. This is due to our policy of hedging
most of our currency exposures back to U.S. dollars. Although this policy
results in less volatility in total return over time than if the portfolio were
unhedged, currency volatility can have a significant effect on the Fund's
investment income. In periods when the dollar declines as it has over the past
two years, the losses from the currency hedging activity offset the investment
income of the portfolio. Conversely, when the dollar appreciates, our


                                       3


currency hedging activity typically generates gains that enhance the investment
income of the Fund. Another way to view this is that much of the Fund's reported
total return -which has been very strong compared to the Index -- is classified
as capital appreciation within the portfolio.

The Fund outperformed its benchmark during the year. Our position in investment
grade and high yield corporate bonds and emerging market securities was the
largest positive contributor relative to our benchmark. Our country selection
was also positive as we were overweighted European markets and zero weighted in
Japan. Our currency exposure was positive for the year relative to the benchmark
as we had established positions in the euro and the Australian, New Zealand and
Canadian dollars relative to the U.S. dollar and all those positions contributed
positively in 2003.

Our outlook for 2004 is favorable for international bonds. We believe that the
performance of global economies will be mixed in the coming year with the U.S.
growing above trend, Japan on trend and Europe below. Government bond yields in
the U.S. will be biased upwards but opportunities for value-added can be found
in European bonds as the European Central Bank is likely to lag any moves by the
Fed to increase interest rates. Non-government sectors such as corporate and
emerging bonds offer value in 2004 as credit quality improves. However, the
excess returns are likely to be more modest than in 2003.

We appreciate your continued support and look forward to working on your behalf
over the next year.


/s/ W. Charles Cook

(a)  The Fund has adopted the provisions of the revised AICPA Audit and
     Accounting Guide for Investment Companies effective January 1, 2001 and
     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to decrease net investment income per share by
     $0.007, increase net realized and unrealized gains and losses per share by
     $0.007 and decrease the ratio of net investment income to average net
     assets from 3.98% to 3.94%. Per share data and ratios/supplemental data for

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                STANDISH MELLON INTERNATIONAL FIXED INCOME 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 International Fixed Income Fund (the "Fund") is a separate
     non-diversified investment series of the Trust.

     The Fund currently offers two classes of shares: Institutional Class and
     Service Class. Expenses of the Fund are borne pro-rata by the holders of
     each class of shares, except for transfer agent fees and an account service
     fee of up to 0.25% of the average daily net assets of the Service Class of
     shares. Each class votes separately as a class only with respect to its own
     distribution plan (Service Class only) or other matters that relate only to
     that class. Shares of each class would receive their pro-rata share of the
     net assets of the Fund (after satisfaction of any class-specific expenses)
     if the Fund were liquidated. In addition, the Trustees declare separate
     dividends on each class of shares.

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

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

     On June 21, 2003, by vote of the Trustees, the name of the Standish
     International Fixed Income Fund was changed to Standish Mellon
     International Fixed Income Fund. In addition, the Declaration of Trust was
     amended to change the name of the Trust from Standish, Ayer & Wood
     Investment Trust to Mellon Institutional Funds Investment Trust. The name
     changes became effective July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

                                       19

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

     B. REPURCHASE AGREEMENTS

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

     C. SECURITIES TRANSACTIONS AND INCOME

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

     D. FOREIGN CURRENCY TRANSACTIONS

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

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

     E. INVESTMENT RISK

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

     F. DISTRIBUTIONS TO SHAREHOLDERS

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

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

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

     G. ALLOCATION OF OPERATING ACTIVITY

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated taking into consideration among other things, the nature
     and type of expense and the relative size of the funds. Investment income,
     common expenses and realized and unrealized gains and losses are allocated
     among the share classes of the Fund based on the relative net assets of
     each class. Transfer agent fees, which are directly attributable to a class
     of shares, are charged to that class' operations. Service fees, which are
     directly attributable to the Service Class shares, are charged to the
     Service Class operations.

     H. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
     Financial Corporation, for overall investment advisory and administrative
     services, and general office facilities is paid monthly at the annual rate
     of 0.40% of the Fund's average daily net assets. Standish Mellon
     voluntarily agreed to limit the Service Class operating expenses (excluding
     brokerage commissions, taxes and extraordinary expenses) for the year ended
     December 31, 2003, so that the Service Class annual operating expenses do
     not exceed the total operating expenses of the Institutional Class (net of
     any expense limitation) for the comparable period plus 0.25% (the maximum
     Service Fee). Pursuant to this agreement, for the year ended December 31,
     2003, Standish Mellon reimbursed the Service Class $11,300 for class
     specific operating expenses. This agreement is voluntary and temporary and
     may be discontinued or revised by Standish Mellon at any time.

     Effective January 28, 2003, the Institutional Class of the Fund began
     imposing a redemption fee of 2% of the net asset value of the shares, with
     certain exceptions, which are redeemed or exchanged less than 90 days from
     the day of their purchase. The redemption fee is paid directly to the Fund,
     and is designed to offset brokerage commissions, market impact, and other
     costs associated with short-term trading. The fee does not apply to shares
     that were acquired through reinvestment of distributions. For the period
     ended December 31, 2003, the Fund received $627 in redemption fees which is
     recorded in capital.

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

(3)  SERVICE FEE:

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

(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

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2003 was as follows:

     At December 31, 2003, 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:

           6,588,065     12/31/2010

     The fund elected to defer to its fiscal year ending December 31, 2004
     $18,544,399 of losses recognized during the period November 1, 2003 to
     December 31, 2003.

(7)  FINANCIAL INSTRUMENTS:

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

     The Fund 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.

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     FUTURES CONTRACTS

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

     At December 31, 2003, the Fund held the following financials futures
     contracts:


                                                                         UNDERLYING FACE

     INTEREST RATE SWAP CONTRACTS

     Interest rate swaps involve the exchange by the Fund with another party of
     their respective commitments to pay or receive interest, e.g., an exchange
     of floating rate payments for fixed rate payments with respect to a
     notional amount of principal. Credit and market risk exist with respect to
     these instruments. If forecasts of interest rates and other market factors
     are incorrect, investment performance will diminish compared to what
     performance would have been if these investment techniques were not used.
     Even if the forecasts are correct, there are risks that the positions may
     correlate imperfectly with the asset or liability being hedged, a liquid
     secondary market may not always exist, or a counterparty to a transaction
     may not perform. The Fund expects to enter into these transactions
     primarily for hedging purposes including, but not limited to, preserving a
     return or spread on a particular investment or portion of its portfolio,
     protecting against currency fluctuations, as a duration management
     technique or protecting against an increase in the price of securities the
     Fund anticipates purchasing at a later date. Interest rate swaps are marked
     to market daily based upon quotations from market makers and the change, if
     any, is recorded as unrealized gain or loss. Payments made or received are
     included as part of interest income. Gains and losses are realized upon the
     expiration or closing of the swap contracts.

     The Fund entered into no such transactions during the year ended December
     31, 2003.

(8)  SECURITY LENDING:

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

     The Fund loaned securities during the year ended December 31, 2003
     resulting in security lending income. At December 31, 2003 the Fund had no
     securities on loan.

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon International Fixed Income 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 Mellon
     Institutional Funds Investment Trust: Standish Mellon International Fixed
     Income Fund (formerly, Standish International Fixed Income Fund) (the
     "Fund") at December 31, 2003, 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
     auditing standards generally accepted in the United States of America,
     which 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
     December 31, 2003 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
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

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

                        STANDISH MELLON FIXED INCOME FUND

                       Management Discussion and Analysis
                                  December 2003

The market environment improved dramatically over the course of the year. As we
began 2003, the war with Iraq, weak job growth and deflation concerns posed
considerable risks to economic growth. However, second half GDP was boosted by
prompt military action, tax cuts and another mortgage refinancing boom. By
mid-year, a pick up in growth pushed interest rates higher. However, the Federal
Reserve has tempered the upward pressure on bond yields by emphasizing their
focus on inflation over growth. With core inflation dipping to 1.1%
year-over-year, and job growth still sluggish, the Fed has little reason to
raise interest rates in the near term.

Over the past year, investment grade and high yield corporate bonds solidly
outperformed other fixed income sectors. As the previous year's negative events
faded from the headlines and corporate profits surged, credit spreads narrowed
significantly. The relative performance of other sectors, especially mortgages
and agencies, paled in comparison to corporate bonds. The mortgage market
suffered amid sharp interest rate moves which resulted in significant hedging
costs and diminished returns. The agency sector also suffered as Freddie Mac's
accounting issues surfaced and regulatory oversight came under harsh scrutiny.

The Fund's outperformance in 2003 was largely driven by the overweight in high
yield and increased allocation to investment grade corporate bonds. Our
underweight to agencies positively contributed to returns. A sizable reduction
to the mortgage position around mid-year was well-timed as we avoided July's
massive underperformance when interest rates backed up and durations extended
sharply. Mortgage security selection was particularly positive in the beginning
of the year as we favored lower coupon issues that benefited from very strong
demand by banks.

Looking ahead, the prospects for economic growth in 2004 appear quite good.
Solid corporate profits should spur business spending and a weaker dollar should
support higher export activity. Inventory rebuilding should also boost GDP in
the first half. With strong productivity and lots of excess capacity, a low
inflation environment should persist. In this environment, the Fed will likely
hold interest rates unchanged for most of the year. The key investment themes
are building the Fund's yield advantage and a bulleted intermediate curve
position. Among the various spread sectors, we favor corporate bonds as we find
the fundamental improvement of credit quality remains solidly in place. Given a
steep yield curve, we are more heavily weighted toward intermediate bonds in the
2 to 5 year area. The Fund's overweight position in commercial mortgage and
asset backed securities emphasizes our intermediate bias. The less-thanbenchmark
weighting in mortgages also fits well with our yield curve strategy as
amortizing assets are less attractive than bullet securities. Finally, the Fund
has a


                                       3



meaningful allocation to international bonds. As the recovery takes hold in the
U.S., we expect European growth prospects will lag, especially with the strength
of the euro. As a result, we look for the yield relationship between U.S.
Treasuries and European bonds will shift in favor of the latter.

As always, we look forward to serving you in the coming year.

(a)  Through its investment in the Portfolio, the Fund has adopted the
     provisions of the revised AICPA Audit and Accounting Guide for Investment
     Companies effective January 1, 2001and began amortizing premium and
     discount on all debt securities on an effective yield basis. The effect of
     this change for the year ended December 31, 2001 was to decrease net
     investment income per share by $0.004, increase net realized and unrealized
     gains and losses per share by $0.004 and decrease the ratio of net
     investment income to average net assets from 6.37% to 6.35%. Per share data
     and ratios/supplemental data for periods prior to January 1, 2001 have not
     been restated to reflect this change in presentation.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                       STANDISH MELLON FIXED INCOME 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 Fixed Income Fund (the "Fund") is a separate diversified
     investment series of the Trust.

     The objective of the Fund is to achieve a high level of current income,
     consistent with conserving principal and liquidity, and secondarily to seek
     capital appreciation when changes in interest rates and economic conditions
     indicate that capital appreciation may be available without significant
     risk to principal. The Fund seeks to achieve its objective by investing all
     of its investable assets in an interest of the Standish Mellon Fixed Income
     Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds
     Master Portfolio (the "Portfolio Trust"), which is organized as a New York
     trust and which has the same investment objective as the Fund. The
     Portfolio seeks to achieve its objective by investing, under normal
     circumstances, at least 80% of net assets in fixed income securities issued
     by U.S. and foreign governments and companies. The value of the Fund's
     investment in the Portfolio reflects the Fund's proportionate interest in
     the net assets of the Portfolio (approximately 100% at December 31, 2003).
     The performance of the Fund is directly affected by the performance of the
     Portfolio. The financial statements of the Portfolio are included elsewhere
     in this report and should be read in conjunction with the Fund's financial
     statements.

     On June 21, 2003, by vote of the Trustees, the name of the Standish Fixed
     Income Fund was changed to Standish Mellon Fixed Income Fund. In addition,
     the Declaration of Trust was amended to change the name of the Trust from
     Standish, Ayer & Wood Investment Trust to Mellon Institutional Funds
     Investment Trust. The name changes became effective July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. In determining the amounts of its dividends,
     the Fund will take into account its share of the income, gains or losses,
     expenses, and any other tax items of the Portfolio. Dividends from net
     investment income and distributions from capital gains, if any, are
     reinvested in additional shares of the Fund unless a shareholder elects to
     receive them in cash. Income and capital gain distributions are determined
     in accordance with income tax regulations which may differ from generally
     accepted accounting principles.

                                       10


                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                       STANDISH MELLON FIXED INCOME FUND

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

     These differences, which may result in distribution reclassifications, are
     primarily due to differing treatments for foreign currency transactions,
     options, futures, interest rate floor, capital loss carryforwards, losses
     deferred due to wash sales, paydown gains and losses, and amortization
     and/or accretion of premiums and discounts on certain securities.

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

     D. EXPENSES

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

     E. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary of Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report. Standish Mellon voluntarily agreed to
     limit the total operating expenses of the Fund and its pro rata share of
     the Portfolio expenses (excluding brokerage commissions, taxes and
     extraordinary expenses) to 0.38% of the Fund's average daily net assets for
     the period from January 1, 2003 through June 30, 2003 and 0.50% for the
     period from July 1, 2003 through December 31, 2003. Pursuant to these
     agreements, for the year ended December 31, 2003, Standish Mellon
     voluntarily reimbursed the Fund for $121,899 of its operating expenses.
     This agreement is voluntary and temporary and may be discontinued or
     revised by Standish Mellon at any time.

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

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended December 31, 2003, aggregated $24,345,488 and $398,371,443,
     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:



                                                                  YEAR ENDED            YEAR ENDED

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

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


     At December 31, 2003, one shareholder held of record approximately 12% of
     the total outstanding shares of the Fund. Investment activity of this
     shareholder could have a material impact on the Fund.

(5)  FEDERAL TAXES:

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

     As of December 31, 2003, the components of distributable earnings on a tax
     basis were as follows:

                                                                     AMOUNT
                                                                  -------------
         Undistributed ordinary income                            $   2,751,000
         Accumulated losses                                        (198,011,405)

     At December 31, 2003, 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
         ------------  ---------------
         $ 43,337,647    12/31/2007
          118,614,149    12/31/2008
           36,020,187    12/31/2009

     The fund elected to defer to its fiscal year ending December 31, 2004
     $39,422 of losses recognized during the period November 1, 2003 to December
     31, 2003.

     The tax character of distributions paid during the fiscal year ended
     December 31, 2003, was as follows:

         Distributions paid from:
           Ordinary income                                           $25,303,177

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

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon Fixed Income 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 Mellon Institutional Funds Trust: Standish Mellon
     Fixed Income Fund (formerly, Standish Fixed Income Fund) (the "Fund"), at
     December 31, 2003, 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 auditing standards generally
     accepted in the United States of America, which 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 correspondence with the custodian, provide a reasonable basis for
     our opinion.

     had not been taken, the ratios would have been:

(a)  The Portfolio has adopted the provisions of the revised AICPA Audit and
     Accounting Guide for Investment Companies effective January 1, 2001 and
     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to decrease the ratio of net investment income to
     average net assets from 6.39% to 6.37%. Ratios for the periods prior to
     January 1, 2001 have not been restated to reflect this change in
     presentation.
+    Total return for the Portfolio has been calculated based on the total
     return for the invested Fund, assuming all distributions were reinvested,
     and adjusted for the difference in expenses as set out in the notes to the
     financial statements. Total return would have been lower in the absence of
     expense waivers.

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

     At December 31, 2003, there was one fund, Standish Mellon Fixed Income Fund
     (the "Fund"), invested in the Portfolio. The value of the Fund's investment
     in the Portfolio reflects the Fund's proportionate interest in the net
     assets of the Portfolio. The Fund's proportionate interest at December 31,
     2003 was approximately 100%.

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

     On June 21, 2003, by vote of the Trustees, the name of the Standish Fixed
     Income Portfolio was changed to Standish Mellon Fixed Income Portfolio. In
     addition, the Declaration of Trust was amended to change the name of the
     Portfolio Trust from Standish, Ayer & Wood Master Portfolio to Mellon
     Institutional Funds Master Portfolio. The name changes became effective
     July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

     B. REPURCHASE AGREEMENTS

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

     C. SECURITIES TRANSACTIONS AND INCOME

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

     D. INCOME TAXES

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

     E. FOREIGN CURRENCY TRANSACTIONS

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

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

     F. INVESTMENT RISK

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

     G. COMMITMENT AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon") for overall investment advisory and
     administrative services is paid monthly at the annual rate of 0.40% of the
     Portfolio's first $250,000,000 of average daily net assets, 0.35% of the
     next $250,000,000 of average daily net assets, and 0.30% of the average
     daily net assets in excess of $500,000,000. Standish Mellon voluntarily
     agreed to limit the Portfolio's total annual operating expenses (excluding
     brokerage commissions, taxes and extraordinary expenses) to 0.38% of the
     Portfolio's average daily net assets for the period from January 1, 2003
     through June 30, 2003 and 0.50% for the period from July 1, 2003 through
     December 31, 2003. Pursuant to these agreements, for the year ended
     December 31, 2003, Standish Mellon voluntarily waived $124,405 of its
     investment advisory fee. This agreement is voluntary and temporary and may
     be discontinued or revised by Standish Mellon at any time.

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

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended December 31, 2003 were as follows:

(4)  FEDERAL TAXES:

                                                                   ------------
         Net unrealized appreciation                               $ 21,112,434
                                                                   ============

(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

                                       30

                     STANDISH MELLON FIXED INCOME PORTFOLIO

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

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

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

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

     A summary of the written put options for the year ended December 31, 2003
     is as follows:

     INTEREST RATE FLOORS

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

     At December 31, 2003, the Portfolio did not hold any open interest rate
     floor agreements.

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     At December 31, 2003, the Portfolio held the following forward foreign
     currency exchange contracts:

     FUTURES CONTRACTS

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

     At December 31, 2003, the Portfolio held the following financials futures
     contracts:



                                                                        UNDERLYING FACE

     At December 31, 2003, the Portfolio had segregated sufficient cash and/or
     securites to cover margin requirements on open futures contracts.

     SWAP AGREEMENTS

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

(6)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

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

     See the Schedule of Investments for outstanding delayed delivery
     transactions.

(7)  SECURITIES LENDING:

     The Portfolio may lend its securities 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

     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

     due on the loans.

     The Portfolio loaned securities during the year ended December 31, 2003
     resulting in security lending income. At December 31, 2003, the Portfolio

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Master Portfolio and the
     Investors of Standish Mellon Fixed Income Portfolio:

     In our opinion, the accompanying statement of asset 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 Mellon
     Institutional Funds Master Portfolio: Standish Mellon Fixed Income
     Portfolio (formerly Standish Fixed Income Portfolio) (the "Portfolio"), at
     December 31, 2003, 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 auditing standards generally
     accepted in the United States of America, which 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 December 31, 2003, 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
December 31, 2003.

In 2003 we experienced a return to risk-taking in the financial markets. It's
worth recalling that for most of 2002, market sentiment was notably bearish,
characterized by a flight to quality. Indeed, the first half of 2002 produced
the worst six-month performance for the S&P 500 Index in more than 30 years,
with a loss of almost 14%.

In contrast, during 2003, the greatest gains were made by the stock market and
the lowest-rated corporate debt. The S&P 500 gained 22%, while the Merrill Lynch
C-Rated High Yield Index advanced 42%. In keeping with the risk-taking trend,
small cap stocks, as measured by the Russell 2000 Index, advanced 45%.
International stocks also have enjoyed a healthy rebound, advancing 17%, as
measured by the MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had
a total return of just 2%, after providing a total return of 12% in 2002, as
measured by the Lehman Treasury Index.

The financial markets were reacting to the increasing strength of the economy.
After several sluggish quarters, economic activity in the U.S. accelerated in
the summer months and remains strong. The sources of strength include a)
continuing monetary ease that has induced substantial mortgage refinancing and
housing activity, b) Federal fiscal stimulus from large new tax cuts and sharp
increases in defense spending, and c) a gradual improvement in business capital
spending after many quarters of stagnation. Sluggish spots to date include
inventory investment, state and local spending, net exports and employment,
although some of these sectors show signs of much-awaited improvement.

The renewal of economic strength has created a schizophrenic year for the bond
markets. Until late June, the market's tone had been set by an expectation of
continued sluggish growth. In June, the Fed made explicit its intent to keep
short-term interest rates low for a "considerable period." But the Fed
announcement was perceived as a disappointment by the market, which promptly
caused a sharp summer selloff in bonds. In September, bonds recouped some of
their losses, as market participants felt the selloff had been overdone. At its
most recent meeting, the Fed edged closer to a less accommodative stance in
dropping the "considerable period" language. Instead, the Fed said it "can be
patient" in not raising rates until signs of inflation become evident. The yield
curve remains very steep, influenced by the Fed at the short end, but with the
intermediate maturities under pressure from the large volume of Treasury
financing in that sector. With the recent bump in yields and inflation still
relatively quiescent, real interest rates have increased to the lower end of
what have been the historic norms.

Looking ahead, it is clear that there are some serious distortions and
imbalances in world economies including structural problems in Japan and core
Europe, the U.S. current account deficit, and the leverage in the consumer
balance sheet. It is impossible to predict when these restraints might undermine
economic activity, but the latter part of 2004 or the year 2005 could be a
period of vulnerability when there will be a loss of incremental fiscal stimulus
as well as the lagged effect of higher interest rates.

Nevertheless, the near term economic outlook has brightened, business activity
has some significant momentum which should carry over into 2004. The result
should be favorable growth, especially in business investment. We expect
inflation to remain modest and corporate profit growth to be reasonably strong.

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

                  STANDISH MELLON SHORT-TERM ASSET RESERVE FUND

                       Management Discussion and Analysis
                                  December 2003

The year 2003 can be broken into two distinctly different environments for the
financial markets. The first half of the year was characterized by the war in
Iraq and a generally weak economy. The second half saw a renewed optimism in the
economy and was highlighted by a moderate rise in interest rates and a strong
equity market. The fixed income market had mixed results during the year, strong
during the first half, weaker during the second. In this mixed environment
Standish Mellon's disciplined approach to investing provided excellent relative
returns. The Standish Mellon Short-Term Asset Reserve Fund returned 1.48% for
the year, surpassing the iMoneyNet All Taxable Fund which returned 0.53%. On an
absolute basis, both the return of the Fund and its benchmark are low due to the
historically low levels of short-term interest rates.

The year started on a cautious note. Early in the first quarter, the war in Iraq
seemed more likely every day and it appeared that the entire economy was waiting
on some resolution to this uncertainty. Consumer spending continued to be
strong, but there were few other bright spots. As the war commenced and was
successfully resolved, some of the uncertainty was eliminated and the stock
market improved. However, through April and May, the lack of any bounce in the
economy led people to speculate that a declining economic, deflationary
environment was possible and that drastic measures might need to be taken to
spark the economy. During this time, interest rates declined to historically low
levels. It was speculated that the Federal Reserve might drop its overnight
funds target to well below 1% and even buy long-term Treasury securities to
reduce long-term interest rates. In June, the rates on two-year Treasury notes
reached a historical low of 1.08%, down nearly 50 basis points from the
beginning of the year. Longer-term interest rates declined even more
dramatically.

The Fed did eventually lower its overnight target rate to 1.00% in late June.
Although this action moved short-term rates to their lowest level yet, the move
was not as dramatic as originally expected. At the same time, economic news
began to indicate stronger growth, particularly in the capital goods sector.
This news led to a rapid increase in long-term interest rates during the summer.
While very-short term rates were held stable by the 1.00% overnight Fed Funds
target, longer-term rates began to anticipate an eventual tightening by the
Federal Reserve. The yield of the two-year note rose to over 2.10% by early
September. Since that time, the economy has continued to strengthen and the
stock market has risen in step. The bond market has also improved somewhat as
the inflationary pressures have not yet reappeared and the Fed has expressed
reluctance to raising rates. Ironically, the two-year Treasury note ended the
year at roughly 1.60%, the same level as it began the year.

In this back and forth interest rate environment, the spread sectors in the
fixed-income market continued to outperform. The deleveraging of corporations
from the prior few years and the gradually improving economy helped narrow
credit spreads to levels not


                                       3


seen since 1997. This spread narrowing was particularly noteworthy in lesser
quality names such as those rated BBB and below.

The performance of the Fund was helped during the year by its use of high
quality spread paper and its ability to extend beyond the technical limits of
money-market funds. High quality spread paper, such as corporate notes and
asset-backed securities, will continue to represent a major portion of the Fund
in the coming year.

By strategy, the duration of the Fund is relatively long compared to its
benchmark. This longer duration combined with a steep yield curve did enable the
fund to benefit from higher long-term yields.

We would also like to note that as of March 31, 2003, portfolio management of
STAR changed from David Hertan to Laurie Carroll and Johnson Moore. As you may
recall, as of July 1, Standish Mellon in Boston combined with two affiliates
within Mellon: Mellon Bond Associates and Certus Asset Advisors. STAR had been
managed by Mr. Hertan from the Boston office. In conjunction with the
combination, all short term asset management was relocated in the Pittsburgh
office, under Ms. Carroll and Mr. Moore.

We remain committed to our disciplined approach with high quality fundamental
research to generate the strong relative returns we have achieved in the past.
We appreciate the continued support of our shareholders.


Sincerely,

/s/ Laurie A. Carroll           /s/ Johnson S. Moore

(a)  Through its investment in the Portfolio, the Fund has adopted the
     provisions of the revised AICPA Audit and Accounting Guide for Investment
     Companies effective January 1, 2001 and began amortizing premium and
     discount on all debt securities on an effective yield basis. The effect of
     this change for the year ended December 31, 2001 was to increase net
     investment income per share by $0.001, decrease net realized and unrealized
     gains and losses per share by $0.001 and increase the ratio of net
     investment income to average net assets by less than 0.01%. Per share data
     and ratios/supplemental data for the periods prior to January 1, 2001 have

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                 STANDISH MELLON SHORT-TERM ASSET RESERVE 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 Short-Term Asset Reserve Fund (the "Fund") is a separate
     diversified investment series of the Trust.

     The objective of the Fund is to achieve a high level of current income
     consistent with preserving principal and liquidity. The Fund seeks to
     achieve its objective by investing all of its investable assets in an
     interest of the Standish Mellon Short-Term Asset Reserve Portfolio (the
     "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio
     (the "Portfolio Trust"), which is organized as a New York trust and which
     has the same investment objective as the Fund. The Portfolio seeks to
     achieve its objective by investing, under normal circumstances, at least
     80% of net assets in dollar-denominated money market instruments,
     short-term fixed income securities and asset-backed securities of U.S. and
     foreign governments, banks and companies. The value of the Fund's
     investment in the Portfolio reflects the Fund's proportionate interest in
     the net assets of the Portfolio (approximately 100% at December 31, 2003).
     The performance of the Fund is directly affected by the performance of the
     Portfolio. The financial statements of the Portfolio are included elsewhere
     in this report and should be read in conjunction with the Fund's financial
     statements.

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

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

     A. INVESTMENT SECURITY VALUATIONS

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. DISTRIBUTIONS TO SHAREHOLDERS

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

                                       10


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

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

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

     D. EXPENSES

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

     E. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary of Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report. Standish Mellon voluntarily agreed to
     limit the total operating expenses of the Fund and its pro rata share of
     the Portfolio expenses (excluding brokerage commissions, taxes and
     extraordinary expenses) to 0.36% of the Fund's average daily net assets for
     the year ended December 31, 2003. Pursuant to this agreement, for the year
     ended December 31, 2003, Standish Mellon voluntarily reimbursed the Fund
     for $101,180 of its operating expenses. This agreement is voluntary and
     temporary and may be discontinued or revised by Standish Mellon at any
     time.

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

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended December 31, 2003, aggregated $153,343,305 and $160,857,552,
     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:


                                                                   YEAR ENDED            YEAR ENDED

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

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


     At December 31, 2003, two shareholders held of record approximately 25% and
     15% 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.

(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 December 31, 2003, the components of distributable earnings on a tax
     basis were as follows:

                                                                    AMOUNT
                                                                  -----------
         Undistributed ordinary income                            $   170,610
         Accumulated losses                                        (2,449,299)

     At December 31, 2003, the Fund, for federal income tax purposes, had
     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
         ------------  ---------------
           $277,757      12/31/2004
            381,998      12/31/2005
             80,787      12/31/2006
            848,377      12/31/2007
            816,280      12/31/2008

     The tax character of distributions paid during the fiscal year ended
     December 31, 2003, was as follows:

         Distributions paid from:
           Ordinary income                                         $3,213,940

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

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon Short-Term Asset Reserve 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 Mellon Institutional Funds Investment Trust: Standish
     Mellon Short-Term Asset Reserve Fund (formerly, Standish Short-Term Asset
     Reserve Fund) (the "Fund"), at December 31, 2003, 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 auditing standards generally accepted in the United States
     of America, which 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
     correspondence with the custodian, provide a reasonable basis for our
     opinion.

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

(a)  The Portfolio has adopted the provisions of the revised AICPA Audit and
     Accounting Guide for Investment Companies effective January 1, 2001 and
     begun amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to increase the ratio of the net investment income to
     average net assets by less than 0.01%. Ratios for the periods prior to
     January 1, 2001 have not been restated to reflect this change in
     presentation.
+    Total return for the Portfolio has been calculated based on the total
     return for the invested Fund, assuming all distributions were reinvested,
     and adjusted for the difference in expenses as set out in the notes to the
     financial statements. Total return would have been lower in the absence of
     expense waivers.

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

     At December 31, 2003 there was one fund, Standish Mellon Short-Term Asset
     Reserve Fund (the "Fund") invested in the Portfolio. The value of the
     Fund's investment in the Portfolio reflects the Fund's proportionate
     interest in the net assets of the Portfolio. The Fund's proportionate
     interest at December 31, 2003 was approximately 100%.

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

     On June 21, 2003, by vote of the Trustees, the name of the Standish
     Short-Term Asset Reserve Portfolio was changed to Standish Mellon
     Short-Term Asset Reserve Portfolio. In addition, the Declaration of Trust
     was amended to change the name of the Trust from Standish, Ayer & Wood
     Master Portfolio to Mellon Institutional Funds Master Portfolio. The name
     changes became effective July 1, 2003.

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

     A. INVESTMENT SECURITY VALUATIONS

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

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

     B. REPURCHASE AGREEMENTS

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

                                       21

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

     C. SECURITIES TRANSACTIONS AND INCOME

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

     D. INCOME TAXES

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

     E. DEFERRED ORGANIZATIONAL EXPENSES

     Costs incurred by the Portfolio in connection with its organization and
     initial registration were amortized on a straight-line basis over the five
     year period since the Portfolio's inception on January 2, 1998.

     F. COMMITMENTS AND CONTINGENCIES

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

(2)  INVESTMENT ADVISORY FEE:

     The investment advisory fee paid to Standish Mellon Asset Management
     Company LLC ("Standish Mellon") for overall investment advisory and
     administrative services is paid monthly at the annual rate of 0.25% of the
     Portfolio's average daily net assets. Standish Mellon voluntarily agreed to
     limit the Portfolio's total annual operating expenses (excluding brokerage
     commissions, taxes and extraordinary expenses) to 0.36% of the Portfolio's
     average daily net assets for the year ended December 31, 2003. Pursuant to
     this agreement, for the year ended December 31, 2003, Standish Mellon
     voluntarily did not impose $16,912 of its investment advisory fees. This
     agreement is voluntary and temporary and may be discontinued or revised by
     Standish Mellon at any time.

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

(4)  FEDERAL TAXES:

(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.

                                       23

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

     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
     December 31, 2003.

     INTEREST RATE FLOORS

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

     At December 31, 2003, the Portfolio did not hold any open interest rate
     floor agreements.

     FUTURES CONTRACTS

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

     At December 31, 2003, the Portfolio held the following financials futures
     contracts:

      At December 31, 2003, the Portfolio had segregated sufficient cash and/or
      securities to cover margin requirements on open futures contracts.

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

(6)  SECURITY LENDING:

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

     The Portfolio loaned securities during the year ended December 31, 2003
     resulting in security lending income. At December 31, 2003, the Portfolio
     had no securities on loan.

(7)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

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

     At December 31, 2003, the Portfolio did not have any delayed delivery
     transactions.

                          REPORT OF INDEPENDENT AUDITORS

     To the Trustees of Mellon Institutional Funds Master Portfolio and the
     Investors of Standish Mellon Short-Term Asset Reserve Portfolio:

     In our opinion, the accompanying statement of asset 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 Mellon
     Institutional Funds Master Portfolio: Standish Mellon Short-Term Asset
     Reserve Portfolio (the "Portfolio"), at December 31, 2003, 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 auditing standards generally accepted in the
     United States of America, which 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 December 31, 2003, by correspondence with the
     custodian, provide a reasonable basis for our opinion.

Item 2.   Code of Ethics.

          As of November 25, 2003, the Registrant has adopted a Code of Ethics
          that applies to the Principal Executive Officer and Principal
          Financial Officer pursuant to the Sarbanes-Oxley Act of 2002. For the
          year ended December 31, 2003, there were no amendments to a provision
          of the Code of Ethics nor were there any waivers granted from a
          provision of the Code of Ethics. A copy of the Registrant's Code of
          Ethics is filed with this Form N-CSR under item 10 (a).

Item 3.   Audit Committee Financial Expert.

          The Registrant's Board of Trustees has determined that the Registrant
          has more than one audit committee financial expert serving on its
          audit committee. The audit committee financial experts serving on the
          Registrant's audit committee are John Hewitt and Caleb Loring III,
          both of whom are independent.

Item 4.   Principal Accountant Fees and Services.

          (a)  AUDIT FEES: The aggregate fees paid and accrued by the Registrant
               for professional services rendered by its independent auditors,
               PricewaterhouseCoopers LLP, for the audit of the Registrant's
               annual financial statements for 2003 and 2002 were $127,776 and
               $122,495, respectively.

          (b)  AUDIT RELATED FEES: The aggregate fees paid or accrued by the
               Registrant for audit-related professional services rendered by
               PricewaterhouseCoopers LLP for 2003 and 2002 were $39,290 and
               $37,310, respectively. Such services and related fees for 2003
               and 2002 included: the preparation of fiscal year end tax
               provisions and distribution requirements necessary to prepare
               annual financial statements.

          (c)  TAX FEES: The aggregate fees paid or accrued by the Registrant
               for professional services rendered by PricewaterhouseCoopers LLP
               for the review of distributions, asset diversification testing
               and preparation of tax returns and extensions for 2003 and 2002
               were $92,214 and $88,628, respectively.

          (d)  ALL OTHER FEES: No such fees were billed to the Registrant by
               PricewaterhouseCoopers LLP for 2003 or 2002.

          (e)  (1) AUDIT COMMITTEE PRE-APPROVAL POLICY: The Registrant's audit
               committee pre-approves all audit and non-audit services to be
               performed by the Registrant's accountant before the accountant is
               engaged by the Registrant to perform such services.

          (e)  (2) 100% of the services described in each of paragraphs (b)
               through (d) of this Item 4 were pre-approved by the Registrant's
               audit committee before the accountant was engaged by the
               Registrant to perform such services.

          (f)  Not applicable.

          (g)  The aggregate non-audit fees billed by the Registrant's
               accountant for services rendered to the Registrant's investment
               adviser by PricewaterhouseCoopers LLP for 2003 and 2002 were
               $50,925 and $0, respectively. Services provided in 2003 included
               consultation and discussions regarding the tax implications
               resulting from the Registrant's change of custodian and fund
               administrator, including change in partnership allocation
               methodology for funds in a master feeder structure and state tax
               issues concerning domicile of master portfolios.

          (h)  Because all of the non-audit services rendered to the
               Registrant's investment adviser or any entity controlling,
               controlled by, or under common control with the investment
               adviser that provides ongoing services to the registrant were
               pre-approved by the Registrant's Audit Committee of the Board of
               Directors and no such non-audit services were not pre-approved,
               the Audit Committee was not asked to consider whether the
               provision of non-audit services rendered to the Registrant's
               investment adviser or any entity controlling, controlled by, or
               under common control with the investment adviser that provides
               ongoing services to the registrant which were not pre-approved by
               the Registrant's Audit Committee is compatible with maintaining
               the principal accountant's independence.

          of an annual report) that has materially affected, or is reasonably
          likely to materially affect, the Registrant's internal control over
