Item 1. Reports to Stockholders.

     (Annual Report for the period 10/01/02 through 9/30/03 is filed herewith).

                   Mellon Institutional Funds Investment Trust

November 28, 2003

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2003.

This year might best be summarized as one in which risk-taking returned to the
financial markets. For most of last year, market sentiment was notably bearish,
characterized by a flight to quality. It's worth recalling that 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, over the past 12 months, the greatest gains have been made by the
stock market and the lowest-rated corporate debt. For the 12 months ended
September 30, the S&P 500 has 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 34%. International
stocks also have enjoyed a healthy rebound, advancing 9%, as measured by the
MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had a total return
of just 3%, after providing a total return of 13% in 2002, as measured by the
Merrill Lynch 5-7 Yr. 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. Soft spots to date include inventory
investment, employment, state and local spending, and net exports.

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. 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's 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,

                   Mellon Institutional Funds Investment Trust
                Standish Mellon Intermediate Tax Exempt Bond Fund

                       Management Discussion and Analysis
                                 September 2003

Steady coupon income enabled municipal bonds to post solid investment results,
even while interest rates fluctuated wildly in the spring and summer of 2003.
For the year ended September 30, 2003, the Standish Intermediate Tax Exempt Bond
Fund produced a total return after expenses of 3.89%. This result trailed the
benchmark performance index (Lehman Muni 3,5,7 and 10 Year Index) return of
4.30%.

Interest rates plunged in the first six months of 2003, causing investors
seeking incremental yield to focus on sectors and securities with more credit
risk. This quest was supported by new rating agency data showing that default
rates among rated municipals are historically miniscule. As rates hit 40-year
lows, however, retail investors' appetites for municipal bonds dwindled, and
funds flowed out of the tax-exempt market and into equities. Declining retail
buying was only partly offset by growing demand among property and casualty
insurers, spurred by renewed profitability in the insurance industry. Throughout
the year we witnessed extraordinary monthly swings in the Fund's returns as
inconsistent demand combined with heavy supply, gyrating interest rates and the
growing prominence of leveraged investors, such as hedge funds, combined to
escalate volatility in the municipal market.

Income-oriented sectors of the tax-free bond market were bid up in the
competition for excess income, and the Fund's holdings in hospital bonds, which
typically carry a significant yield premium, outperformed. In contrast, a large
allocation to lower-yielding triple-A rated insured bonds lagged. Housing bonds
turned in strong results when rates rose in the summer and generated favorable
relative returns for the 12-month period. The Fund continues to hold a large
strategic weighting in this more defensive sector.

Despite well-publicized state budget shortfalls across the country, tax-backed
general obligations were among the best performing municipal sectors. California
state general obligations, buffeted by a rating downgrade, massive new issuance
volume and the pending governor's recall election, reached their lowest relative
values in July. Nevertheless, valuations improved as uncertainties receded over
the state's rating and budget. We are confident California's creditworthiness
will improve over the next 12 months, but expect prices will fluctuate with the
steady barrage of political and economic news reports. New York City's general
obligation bonds saw steadily higher valuations after reaching a low point in
late 2002. By quickly and decisively balancing fiscal 2003 financial operations,
the City's administration was able to alleviate many investor concerns over
long-term creditworthiness. We used price weakness throughout the past year to
build substantial positions in the Fund in both California and New York City
general obligations.

With municipal yields still very low, we are maintaining our strategic emphasis
on high quality, intermediate term municipals. We will focus on sector and
security selection to produce consistently competitive returns by generating
excess income. In addition, it is important to note that municipals are usually
more defensive instruments, ordinarily holding their values better than
Treasuries do when rates begin to rise.

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

/s/ STEVEN W. HARVEY                                  /s/ CHRISTINE TODD

               STANDISH MELLON INTERMEDIATE TAX EXEMPT BOND FUND

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

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

      On June 21, 2003, by vote of the Trustees, the name of the Standish
      Intermediate Tax Exempt Bond Fund was changed to Standish Mellon
      Intermediate Tax Exempt 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

      Municipal bonds are normally valued on the basis of valuations furnished
      by a pricing service. Taxable fixed income obligations, if any, for which
      price quotations are readily available are normally valued at the last
      sales prices on the exchange or market on which they are primarily traded,
      or if not listed or no sale, at the last quoted bid prices. Securities
      (including restricted 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. 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.

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

     D. DISTRIBUTIONS TO SHAREHOLDERS

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

      Income and capital gains distributions are determined in accordance with
      income tax regulations which may differ from accounting principles
      generally accepted in the United States of America. These differences,
      which may result in distribution reclassifications, are primarily due to
      differing treatments for non-taxable dividends, capital loss
      carryforwards, post-October losses, losses deferred due to wash sales and
      net operating losses.

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

     E. EXPENSES

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

     F. COMMITMENTS AND CONTINGENCIES

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

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

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
      Financial Corporation, for overall investment advisory, administrative
      services, and general office facilities, is paid at an annual rate of
      0.40% of the Fund's average daily net assets. Standish Mellon voluntarily
      agreed to limit the total Fund operating expenses (excluding litigation,
      indemnification and other extraordinary expenses) to 0.65% of the Fund's
      average daily net assets for the year ended September 30, 2003. Pursuant
      to this agreement, for the year ended September 30, 2003, Standish Mellon
      voluntarily waived a portion of its advisory fee in the amount of $20,927.
      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
      investments, for the year ended September 30, 2003 were $32,143,303 and
      $47,875,497, respectively. For the year ended September 30, 2003, the Fund
      did not purchase or sell any long-term U.S. Government securities.

(4)  SHARES OF BENEFICIAL INTEREST:

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



                                                                 YEAR ENDED             YEAR ENDED

      At September 30, 2003, the Fund had one shareholder of record owning
      approximately 18% of the Fund's outstanding shares. 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 all of its taxable income for its fiscal year.
      Dividends paid by the Fund from net interest earned on tax-exempt
      municipal bonds are not includable by shareholders as gross income for
      federal income tax purposes because the Fund intends to meet certain
      requirements of the Internal Revenue Code applicable to regulated
      investment companies which will enable the Fund to pay exempt-interest
      dividends.

      The tax basis components of distributable earnings and the federal tax
      cost as of September 30, 2003 was as follows:

         Unrealized appreciation                               $3,834,806
         Unrealized depreciation                                 (155,365)

(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

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

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

     FUTURES CONTRACTS

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

      At September 30, 2003, the Fund held no outstanding futures contracts.

(7)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

      See Schedule of Investments for outstanding delayed delivery transactions.

(8)  LINE OF CREDIT:

      The Fund, other funds in the Trust and subtrusts in the Mellon
      Institutional Funds Master Portfolio (the "Portfolio Trust") are parties
      to a committed line of credit facility, which enables each portfolio/fund
      to borrow, in the aggregate, up to $35 million. Interest is charged to
      each participating portfolio/fund based on its borrowings at a rate equal
      to the Federal Funds effective rate plus 1/2 of 1%. In addition, a
      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 September 30, 2003, the expense related to the commitment fee was
      $3,454 for the Fund.

      During the year ended September 30, 2003, the Fund had no borrowings under
      the credit facility.

                          REPORT OF INDEPENDENT AUDITORS

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

   In our opinion, the accompanying statement of assets and liabilities,
   including the schedule of investments, and the related statements of
   operations and of changes in net assets and the financial highlights present
   fairly, in all material respects, the financial position of Mellon
   Institutional Funds Investment Trust: Standish Mellon Intermediate Tax Exempt
   Bond Fund (formerly, Standish Intermediate Tax Exempt Bond Fund) (the
   "Fund"), at September 30, 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 September 30, 2003 by correspondence with the
   custodian and brokers, provide a reasonable basis for our opinion.

                   Mellon Institutional Funds Investment Trust

November 28, 2003

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2003.

This year might best be summarized as one in which risk-taking returned to the
financial markets. For most of last year, market sentiment was notably bearish,
characterized by a flight to quality. It's worth recalling that 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, over the past 12 months, the greatest gains have been made by the
stock market and the lowest-rated corporate debt. For the 12 months ended
September 30, the S&P 500 has 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 34%. International
stocks also have enjoyed a healthy rebound, advancing 9%, as measured by the
MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had a total return
of just 3%, after providing a total return of 13% in 2002, as measured by the
Merrill Lynch 5-7 Yr. 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. Soft spots to date include inventory
investment, employment, state and local spending, and net exports.

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. 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's 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.

                   Mellon Institutional Funds Investment Trust
         Standish Mellon Massachusetts Intermediate Tax Exempt Bond Fund
                       Management Discussion and Analysis
                                 September 2003

Steady coupon income enabled municipal bonds to post solid investment results,
even while interest rates fluctuated wildly in the spring and summer of 2003.
For the year ended September 30, 2003, the Standish Mellon Massachusetts
Intermediate Tax Exempt Bond Fund produced a total return after expenses of
3.20%. This result trailed the benchmark performance index (Lehman Muni 3,5,7
and 10 Year Index) return of 4.30%. Please note that the Massachusetts Fund
invests only in bonds where interest is exempt from Massachusetts and federal
income taxes, while the benchmark index is national in scope.

Interest rates plunged in the first six months of 2003, causing investors
seeking incremental yield to focus on sectors and securities with more credit
risk. This quest was supported by new rating agency data showing that default
rates among rated municipals are historically miniscule. As rates hit 40-year
lows, however, retail investors' appetites for municipal bonds dwindled, and
funds flowed out of the tax-exempt market and into equities. Declining retail
buying was only partly offset by growing demand among property and casualty
insurers, spurred by renewed profitability in the insurance industry. Throughout
the year we witnessed extraordinary monthly swings in the Fund's returns as
inconsistent demand combined with heavy supply, gyrating interest rates and the
growing prominence of leveraged investors, such as hedge funds, combined to
escalate volatility in the municipal market.

Income-oriented sectors of the tax-free bond market were bid up in the
competition for excess income, and the Fund's holdings in hospital bonds, which
typically carry a significant yield premium, outperformed. In contrast, a large
allocation to lower-yielding triple-A rated insured bonds lagged. Housing bonds
turned in strong results when rates rose in the summer and generated favorable
relative returns for the 12-month period. The Fund continues to hold a large
strategic weighting in this more defensive sector.

Massachusetts bonds benefited from scarcity as fewer new bonds were offered for
sale. Despite suggestions of continuing budget problems in fiscal 2004,
Massachusetts state general obligations performed well, which was favorable for
the Fund's relative returns. Light new issue volume, combined with strong demand
from individual investors, also caused government-backed pre-refunded bonds to
register strong results. An underweight position in this sector detracted from
the Fund's performance.

With municipal yields still very low, we are maintaining our strategic emphasis
on high quality, intermediate term municipals. We will focus on sector and
security selection to produce consistently competitive returns by generating
excess income. In addition, it is important to note that municipals are usually
more defensive instruments, ordinarily holding their values better than
Treasuries do when rates begin to rise.

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

        STANDISH MELLON MASSACHUSETTS INTERMEDIATE TAX EXEMPT BOND FUND

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

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

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

      On June 21, 2003, by vote of the Trustees, the name of the Standish
      Massachusetts Intermediate Tax Exempt Bond Fund was changed to Standish
      Mellon Massachusetts Intermediate Tax Exempt 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

      Municipal bonds are normally valued on the basis of valuations furnished
      by a pricing service. Taxable fixed income obligations, if any, for which
      price quotations are readily available are normally valued at the last
      sales prices on the exchange or market on which they are primarily traded,
      or if not listed or no sale, at the last quoted bid prices. Securities
      (including restricted 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. 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.

     D. DISTRIBUTIONS TO SHAREHOLDERS

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

      Income and capital gains distributions are determined in accordance with
      income tax regulations which may differ from accounting principles
      generally accepted in the United States of America. These differences,
      which may result in distribution reclassifications, are primarily due to
      differing treatments for non-taxable dividends, capital loss
      carryforwards, post-October losses, losses deferred due to wash sales and
      net operating losses.

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

     E. EXPENSES

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

     F. COMMITMENTS AND CONTINGENCIES

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

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

      The investment advisory fee paid to Standish Mellon Asset Management
      Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon
      Financial Corporation, for overall investment advisory, administrative
      services, and general office facilities, is paid at an annual rate of
      0.40% of the Fund's average daily net assets. Standish Mellon voluntarily
      agreed to limit the total Fund operating expenses (excluding litigation,
      indemnification and other extraordinary expenses) to 0.65% of the Fund's
      average daily net assets for the year ended September 30, 2003. Pursuant
      to this agreement, for the year ended September 30, 2003, Standish Mellon
      voluntarily waived a portion of its advisory fee in the amount of $33,257.
      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
      investments, for the year ended September 30, 2003 were $14,716,321 and
      $27,313,027, respectively. For the year ended September 30, 2003, the Fund
      did not purchase or sell any long-term U.S. Government securities.

(4)  SHARES OF BENEFICIAL INTEREST:

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



                                                                 YEAR ENDED             YEAR ENDED

         Shares sold                                                226,054               233,126

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

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


      At September 30, 2003, the Fund had one shareholder of record owning
      approximately 30% of the Fund's outstanding shares. 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 all of its taxable income for its fiscal year.
      Dividends paid by the Fund from net interest earned on tax-exempt
      municipal bonds are not includable by shareholders as gross income for
      federal income tax purposes because the Fund intends to meet certain
      requirements of the Internal Revenue Code applicable to regulated
      investment companies which will enable the Fund to pay exempt-interest
      dividends.

      The tax basis components of distributable earnings and the federal tax
      cost as of September 30, 2003 was as follows:

         Unrealized appreciation                                $2,840,885
         Unrealized depreciation                                   (76,435)
                                                                ----------
         Net unrealized appreciation/depreciation                2,764,450
         Undistributed tax-exempt income                            55,384
         Undistributed capital gains                             1,229,428
                                                                ----------
         Total distributable earnings                           $4,049,262
                                                                ==========
         Cost for federal income tax purposes                   $48,298,723

      The tax character of distributions paid during the fiscal year ended
      September 30, 2003, was as follows:

                                                                  AMOUNT
                                                                ----------
         Distributions paid from:
           Tax-exempt income                                    $2,244,407
           Ordinary income                                              59
           Capital gains                                           113,195

(6)  FINANCIAL INSTRUMENTS:

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

                                       14


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

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

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

     FUTURES CONTRACTS

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

      At September 30, 2003, the Fund held no outstanding futures contracts.

(7)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

      At September 30, 2003, the Fund had no outstanding delayed delivery
      transactions.

(8)  LINE OF CREDIT:

      The Fund, other funds in the Trust and subtrusts in the Mellon
      Institutional Funds Master Portfolio (the "Portfolio Trust") are parties
      to a committed line of credit facility, which enables each portfolio/fund
      to borrow, in the aggregate, up to $35 million. Interest is charged to
      each participating portfolio/fund based on its borrowings at a rate equal
      to the Federal Funds effective rate plus 1/2 of 1%. In addition, a
      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 September 30, 2003, the expense related to the commitment fee was
      $2,719 for the Fund.

      During the year ended September 30, 2003, the Fund had no borrowings under
      the credit facility.

                          REPORT OF INDEPENDENT AUDITORS

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

   In our opinion, the accompanying statement of assets and liabilities,
   including the schedule of investments, and the related statements of
   operations and of changes in net assets and the financial highlights present
   fairly, in all material respects, the financial position of Mellon
   Institutional Funds Investment Trust: Standish Mellon Massachusetts
   Intermediate Tax Exempt Bond Fund (formerly, Standish Massachusetts
   Intermediate Tax Exempt Bond Fund) (the "Fund"), at September 30, 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 September 30, 2003
   by correspondence with the custodian and brokers, provide a reasonable basis
   for our opinion.

                   Mellon Institutional Funds Investment Trust

November 28, 2003

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2003.

This year might best be summarized as one in which risk-taking returned to the
financial markets. For most of last year, market sentiment was notably bearish,
characterized by a flight to quality. It's worth recalling that 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, over the past 12 months, the greatest gains have been made by the
stock market and the lowest-rated corporate debt. For the 12 months ended
September 30, the S&P 500 has 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 34%. International
stocks also have enjoyed a healthy rebound, advancing 9%, as measured by the
MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had a total return
of just 3%, after providing a total return of 13% in 2002, as measured by the
Merrill Lynch 5-7 Yr. 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. Soft spots to date include inventory
investment, employment, state and local spending, and net exports.

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. 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's 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,

                   Mellon Institutional Funds Investment Trust
               The Boston Company Small Capitalization Equity Fund

                       Management Discussion and Analysis
                                 September 2003

The Boston Company Small Capitalization Equity Fund's return for the fiscal year
ended September 30, 2003 was 33.54% versus 41.72% for the Russell 2000 Growth
Index. The strong absolute performance was the fund's best since the fiscal year
ended September 2000. The fund lagged on a relative basis, following
outperformance in the prior fiscal year.

Market Environment

Equity markets were positive during the year, with smaller stocks leading large
and growth outperforming value. The broad Russell 3000 Index, which encompasses
large and small companies, was up 25.9%. Smaller companies, as measured by the
Russell 2000, were up 36.5%, while the large cap Russell 1000 gained 25.1%.
While growth outperformed value across all capitalization ranges, the widest
spread was in the smallest stocks - in both the small cap and mid cap indices
growth outpaced value by over 10 percentage points.

Strong stock returns were driven by a firming economic outlook, albeit one with
little job creation. GDP growth increased during the year to a 3.3% annual rate
in the quarter ended June 30, up from 1.4% in the prior quarter, spurred by a
7.3% jump in business spending. Leading indicators continue to foretell
expansion, up 2.4% in the six months through August. The recovery's soft spot
remains employment. While initial claims for unemployment ticked down in August
to around 400,000, a level considered the dividing line between job creation and
job loss, we have not yet seen a robust improvement in the jobs market.

Portfolio Strategy & Results

The last twelve months were a particularly difficult period for active managers
as the lowest quality stocks drove index returns. Recent work done by Merrill
Lynch shows that the lowest quality companies, as ranked by Standard and Poor's,
were up 57.8% in the nine months ended September 30, while the highest quality
companies were up 13.4%. Further, a majority of these stocks have
characteristics that do not appeal to many investors - low earnings, high
multiples and weak fundamentals. Historically, these lower quality stocks tend
to lead coming out of a recession as investors make an asset allocation trade
into more risky assets. In small caps, this was seen most recently through the
sharply increased trading volume in exchange traded funds (ETFs) that focus on
smaller company indexes. Specifically, Russell 2000 ETF volume more than doubled
to $4.7 billion from December 2002 to August 2003.



The portfolio's relative underperformance during this period was concentrated
primarily in technology and services. In technology a combination of an
underweight position (generally reduced throughout the year) and weak stock
selection had a negative impact on performance. The underperformance in services
was driven by selection. Specifically, positions in Central Parking and
Scholastic had a negative impact on returns. Central Parking's focus on parking
lots in metropolitan areas led to poor results as fewer people drove to work
during the downturn and corporate layoffs continued. Scholastic's book clubs
proved to be more economically sensitive than expected, pulling down earnings.
On the positive side, retail holdings such as Children's Place and Linens `n'
Things contributed to outperformance in the consumer sector. Similarly, the
fund's energy holdings more than doubled the returns of those in the benchmark,
helped by positions in Patina Oil & Gas and Key Energy Services.

Outlook

Investors' increasing love of risk over the last 12 months has led to a near
term focus on the lowest rated, most leveraged, most expensive companies. We
believe that, for the market to sustain its upward momentum, higher quality
companies - those with strong growth rates, real earnings, and reasonable
valuations relative to their growth rates - will likely assume market
leadership. This would result in a shift away from some of the best performing
sectors, like technology and biotech, to areas that exhibit recognizable,
sustainable sources of earnings. These areas, which could include consumer
staples and industrial companies, are those we believe hold the best long-term
potential for our investors.


Sincerely,

/s/ W. RANDALL WATTS

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

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

      The objective of the Fund is to achieve long-term growth of capital. The
      Fund seeks to achieve its objective by investing, under normal
      circumstances, at least 80% of net assets in equity securities of small
      cap U.S. companies with total market capitalizations equal to or less than
      75% of the average total market capitalization of the largest companies
      included in the Russell 2000 Growth Index measured at the end of each of
      the previous twelve months.

      On June 21, 2003, by vote of the Trustees, the name of the Standish Small
      Capitalization Equity Fund was changed to The Boston Company Small
      Capitalization Equity 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, or the
      NASDAQ official close if applicable, in the principal market in which such
      securities are primarily traded. Securities (including illiquid
      securities) for which quotations are not readily available are valued at
      their fair value as determined in good faith under consistently applied
      procedures under the general supervision of the Trustees.

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

     B. 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. Dividends representing a return of capital are
      reflected as a reduction of cost, when the amount of return of capital is
      conclusively determined.

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

     D. DISTRIBUTIONS TO SHAREHOLDERS

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

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

     E. EXPENSES

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

     F. COMMITMENTS AND CONTINGENCIES

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

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

      On June 21, 2003, by vote of the Trustees, as part of a reorganization of
      the investment management operations of certain Mellon Financial
      Corporation's subsidiaries, Standish Mellon Asset Management Company LLC
      ("Standish Mellon") transferred all of its rights and obligations under
      the investment advisory agreements between Standish Mellon and the Trust
      on behalf of the Fund to The Boston Company Asset Management, LLC
      ("TBCAM"). The transfer of rights and obligations became effective
      July 1, 2003. For the year ended September 30, 2003, the Fund paid $83,888
      and $33,269 in investment advisory fees to Standish Mellon and TBCAM,
      respectively.

      The investment advisory fee paid to TBCAM for overall investment advisory,
      administrative services, and general office facilities, is paid monthly at
      the annual rate of 0.60% of the Fund's average daily net assets. Standish
      Mellon and TBCAM voluntarily agreed to limit total Fund operating expenses
      (excluding brokerage commissions, taxes and extraordinary expenses) to
      0.74% of the Fund's average daily net assets for the year ended
      September 30, 2003. Pursuant to this agreement, for the year ended
      September 30, 2003, Standish Mellon and TBCAM collectively and voluntarily
      did not impose its investment advisory fee of $117,157 and reimbursed the
      Fund for $12,339 of its operating expenses. Effective November 1, 2003,
      the voluntary expense limitation was changed to 1.00% of the Fund's
      average daily net assets. This agreement is voluntary and temporary and
      may be discontinued or revised by TBCAM at any time.

      Effective January 28, 2003, the Fund began imposing a redemption fee of 2%
      of the net asset value of the shares, with certain exceptions, which are
      redeemed or exchanged less than 90 days from the day of their purchase.
      The redemption fee is paid directly to the Fund, and is designed to offset
      brokerage commissions, market impact, and other costs

      associated with short-term trading. The fee does not apply to shares that
      were acquired through reinvestment of distributions. The redemption fee is
      applicable to shares of the Fund purchased on or after January 28, 2003.
      For the period ended September 30, 2003, the Fund received no redemption
      fees.

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

(3)  PURCHASES AND SALES OF INVESTMENTS:

      Purchases and proceeds from sales of investments, other than short-term
      obligations for the year ended September 30, 2003, were $47,904,391 and
      $50,396,743, respectively. For the year ended September 30, 2003, the Fund
      did not purchase or sell any long-term U.S. Government securities.

(4)  SHARES OF BENEFICIAL INTEREST:

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



                                                                 YEAR ENDED             YEAR ENDED

      At September 30, 2003, three shareholders held of record approximately
      29%, 27%, and 12% 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.

      The tax basis components of distributable earnings and the federal tax
      cost as of September 30, 2003, was as follows:

         Unrealized appreciation                                    $ 2,909,847

              THE BOSTON COMPANY SMALL CAPITALIZATION EQUITY FUND

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

      At September 30, 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
         ------------  ---------------
          $3,406,176       9/30/2009
           6,056,870       9/30/2010
             752,919       9/30/2011

      The tax character of distributions paid during the fiscal year ended
      September 30, 2003, was as follows:

         Distributions paid from:
           Ordinary income                                             $1,316

(6)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

      The Fund did not enter into option transactions during the year ended
      September 30, 2003.

                         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 September 30, 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 September 30, 2003
      resulting in security lending income. At September 30, 2003, the Fund had
      no securities on loan.

(8)  LINE OF CREDIT:

      The Fund, and other funds in the Trust and subtrusts in the Mellon
      Institutional Funds Master Portfolio Trust (the "Portfolio Trust") are
      parties to a committed line of credit facility, which enables each
      portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is
      charged to each participating portfolio/fund based on its borrowings at a
      rate equal to the Federal Funds effective rate plus 1/2 of 1%. In
      addition, a 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 September 30, 2003, the commitment fee was $810 for the Fund.

      During the year ended September 30, 2003, the Fund had no borrowings under
      the credit facility.

                          REPORT OF INDEPENDENT AUDITORS

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

   In our opinion, the accompanying statement of assets and liabilities,
   including the schedule of investments and the related statements of
   operations and of changes in net assets and the financial highlights present
   fairly, in all material respects, the financial position of Mellon
   Institutional Funds Investment Trust: The Boston Company Small Capitalization
   Equity Fund (formerly, Standish Small Capitalization Equity Fund) (the
   "Fund") at September 30, 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
   September 30, 2003, by correspondence with the custodian and brokers, provide
   a reasonable basis for our opinion.

                   Mellon Institutional Funds Investment Trust

November 28, 2003

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2003.

This year might best be summarized as one in which risk-taking returned to the
financial markets. For most of last year, market sentiment was notably bearish,
characterized by a flight to quality. It's worth recalling that 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, over the past 12 months, the greatest gains have been made by the
stock market and the lowest-rated corporate debt. For the 12 months ended
September 30, the S&P 500 has 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 34%. International
stocks also have enjoyed a healthy rebound, advancing 9%, as measured by the
MSCI EAFE Index. In comparison, intermediate U.S. Treasuries had a total return
of just 3%, after providing a total return of 13% in 2002, as measured by the
Merrill Lynch 5-7 Yr. 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. Soft spots to date include inventory
investment, employment, state and local spending, and net exports.

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. 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's 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,

                   Mellon Institutional Funds Investment Trust
             The Boston Company Small Cap Tax Sensitive Equity Fund

                       Management Discussion and Analysis
                                 September 2003

The Boston Company Small Cap Tax Sensitive Equity Fund's return for the fiscal
year ended September 30, 2003 was 31.29% versus 41.72% for the Russell 2000
Growth Index. The strong absolute performance was the fund's best since the
fiscal year ended September 2000. The fund lagged on a relative basis, following
outperformance in the prior fiscal year.

Market Environment

Equity markets were positive during the year, with smaller stocks leading large
and growth outperforming value. The broad Russell 3000 Index, which encompasses
large and small companies, was up 25.9%. Smaller companies, as measured by the
Russell 2000, were up 36.5%, while the large cap Russell 1000 gained 25.1%.
While growth outperformed value across all capitalization ranges, the widest
spread was in the smallest stocks - in both the small cap and mid cap indices
growth outpaced value by over 10 percentage points.

Strong stock returns were driven by a firming economic outlook, albeit one with
little job creation. GDP growth increased during the year to a 3.3% annual rate
in the quarter ended June 30, up from 1.4% in the prior quarter, spurred by a
7.3% jump in business spending. Leading indicators continue to foretell
expansion, up 2.4% in the six months through August. The recovery's soft spot
remains employment. While initial claims for unemployment ticked down in August
to around 400,000, a level considered the dividing line between job creation and
job loss, we have not yet seen a robust improvement in the jobs market.

Portfolio Strategy & Results

The last twelve months were a particularly difficult period for active managers
as the lowest quality stocks drove index returns. Recent work done by Merrill
Lynch shows that the lowest quality companies, as ranked by Standard and Poor's,
were up 57.8% in the nine months ended September 30, while the highest quality
companies were up 13.4%. Further, a majority of these stocks have
characteristics that do not appeal to many investors - low earnings, high
multiples and weak fundamentals. Historically, these lower quality stocks tend
to lead coming out of a recession as investors make an asset allocation trade
into more risky assets. In small caps, this was seen most recently through the
sharply increased trading volume in exchange traded funds (ETFs) that focus on
smaller company indexes. Specifically, Russell 2000 ETF volume more than doubled
to $4.7 billion from December 2002 to August 2003.



The portfolio's relative underperformance during this period was concentrated
primarily in technology and services. In technology a combination of an
underweight position (generally reduced throughout the year) and weak stock
selection had a negative impact on performance. The underperformance in services
was driven by selection. Specifically, positions in Central Parking and
Scholastic had a negative impact on returns. Central Parking's focus on parking
lots in metropolitan areas led to poor results as fewer people drove to work
during the downturn and corporate layoffs continued. Scholastic's book clubs
proved to be more economically sensitive than expected, pulling down earnings.
On the positive side, retail holdings such as Children's Place and Linens `n'
Things contributed to outperformance in the consumer sector. Similarly, the
fund's energy holdings more than doubled the returns of those in the benchmark,
helped by positions in Patina Oil & Gas and Key Energy Services.

Outlook

Investors' increasing love of risk over the last 12 months has led to a near
term focus on the lowest rated, most leveraged, most expensive companies. We
believe that, for the market to sustain its upward momentum, higher quality
companies - those with strong growth rates, real earnings, and reasonable
valuations relative to their growth rates - will likely assume market
leadership. This would result in a shift away from some of the best performing
sectors, like technology and biotech, to areas that exhibit recognizable,
sustainable sources of earnings. These areas, which could include consumer
staples and industrial companies, are those we believe hold the best long-term
potential for our investors.


Sincerely,

/s/ W. RANDALL WATTS

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

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

(1)  SIGNIFICANT ACCOUNTING POLICIES:

      Mellon Institutional Funds Investment Trust (the "Trust") is organized as
      a Massachusetts business trust and is registered under the Investment
      Company Act of 1940, as amended, as an open-end, management investment
      company. The Boston Company Small Cap Tax-Sensitive Equity Fund (the
      "Fund") is a separate diversified investment series of the Trust.

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

      On June 21, 2003, by vote of the Trustees, the name of the Standish Small
      Cap Tax-Sensitive Equity Fund was changed to The Boston Company Small Cap
      Tax-Sensitive Equity 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, or the
      NASDAQ official close if applicable, in the principal market in which such
      securities are primarily traded. Securities (including illiquid
      securities) for which quotations are not readily available are valued at
      their fair value as determined in good faith under consistently applied
      procedures under the general supervision of the Trustees.

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

     B. 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. Dividends representing a return of capital are
      reflected as a reduction of cost, when the amount of return of capital is
      conclusively determined.

             THE BOSTON COMPANY SMALL CAP TAX-SENSITIVE EQUITY FUND

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

     D. DISTRIBUTIONS TO SHAREHOLDERS

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

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

     E. EXPENSES

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

     F. COMMITMENTS AND CONTINGENCIES

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

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

      On June 21, 2003, by vote of the Trustees, as part of a reorganization of
      the investment management operations of certain Mellon Financial
      Corporation's subsidiaries, Standish Mellon Asset Management Company LLC
      ("Standish Mellon") transferred all of its rights and obligations under
      the investment advisory agreements between Standish Mellon and the Trust
      on behalf of the Fund to The Boston Company Asset Management, LLC
      ("TBCAM"). The transfer of rights and obligations became effective
      July 1, 2003. For the year ended September 30, 2003, the Fund paid
      $521,768 and $216,441 in investment advisory fees to Standish Mellon and
      TBCAM, respectively.

      The investment advisory fee paid to TBCAM for overall investment advisory,
      administrative services, and general office facilities, is paid monthly at
      the annual rate of 0.80% of the Fund's average daily net assets. Standish
      Mellon and TBCAM voluntarily agreed to limit total Fund operating expenses
      (excluding brokerage commissions, taxes and extraordinary expenses) to
      1.00% of the Fund's average daily net assets for the year ended
      September 30, 2003. Pursuant to this agreement, for the year ended
      September 30, 2003, Standish Mellon and TBCAM collectively and voluntarily
      did not impose $64,845 of its investment advisory fee. Effective
      November 1, 2003, the voluntary expense limitation was changed to 1.10% of
      the Fund's average daily net assets. This agreement is voluntary and
      temporary and may be discontinued or revised by TBCAM at any time.

      Effective January 28, 2003, the Fund began imposing a redemption fee of 2%
      of the net asset value of the shares, with certain exceptions, which are
      redeemed or exchanged less than 90 days from the day of their purchase.
      The redemption fee is paid directly to the Fund, and is designed to offset
      brokerage commissions, market impact, and other costs associated with
      short-term trading. The fee does not apply to shares that were acquired
      through reinvestment of distributions. The redemption fee is applicable to
      shares of the Fund purchased on or after January 28, 2003. For the period
      ended September 30, 2003, the Fund received $84 in redemption fees.

      At September 30, 2003, three shareholders held of record approximately
      36%, 10% and 10% of the total outstanding shares of the Fund. Investment
      activity of these shareholders could have a material impact on the Fund.

(5)  FEDERAL TAXES:

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

      The tax basis components of distributable earnings and the federal tax
      cost as of September 30, 2003, was as follows:

         Unrealized appreciation                                    $15,092,383
         Unrealized depreciation                                     (1,395,315)

         Total distributable earnings                               $(3,978,550)
                                                                    ===========
         Cost for federal income tax purposes                       $93,367,047

      At September 30, 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)  FINANCIAL INSTRUMENTS:

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

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

     OPTIONS

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

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

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

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

      At September 30, 2003, the Fund held the following financial futures
      contracts.



                                                                        UNDERLYING FACE

(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 September 30, 2003
      resulting in security lending income. At September 30, 2003, the Fund had
      no securities on loan.

(8)  LINE OF CREDIT:

      The Fund, and other funds in the Trust and subtrusts in the Mellon
      Institutional Funds Master Portfolio Trust (the "Portfolio Trust") are
      parties to a committed line of credit facility, which enables each
      portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is
      charged to each participating portfolio/fund based on its borrowings at a
      rate equal to the Federal Funds effective rate plus 1/2 of 1%. In
      addition, a 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 September 30, 2003, the commitment fee was $3,727 for the Fund.

      During the year ended September 30, 2003, the Fund had no borrowings under
      the credit facility.

                          REPORT OF INDEPENDENT AUDITORS

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

   In our opinion, the accompanying statement of assets and liabilities,
   including the schedule of investments, and the related statements of
   operations and of changes in net assets and the financial highlights present
   fairly, in all material respects, the financial position of Mellon
   Institutional Funds Investment Trust: The Boston Company Small Cap
   Tax-Sensitive Equity Fund (formerly, Standish Small Cap Tax-Sensitive Equity
   Fund) (the "Fund"), at September 30, 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 September 30, 2003 by correspondence with the
   custodian and brokers, provide a reasonable basis for our opinion.
