MELLON INSTITUTIONAL FUNDS

September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

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,
Barbara McCann
President

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

For the year ended September 30, 2007, The Mellon Large Cap Growth Fund had a
total return of 17.5% compared to its benchmark, the Russell 1000 Growth index
which returned 19.4%. The twelve-month period ended September 30, 2007 concluded
one of the more challenging periods in recent memory as both credit and equity
markets witnessed volatility increasing, risk appetites abating, and liquidity
disappearing. An overheating China and an economic slowdown worried investors in
February, but companies managed to continue to grow earnings, calming investors'
fears through the second quarter. Continued deterioration in the housing market
and signs of mounting credit losses at Wall Street banks ignited a flight to
quality in July. Both occurrences witnessed global investors fleeing risky
assets for the safety of liquid short-term investment vehicles. Investors bid up
the price of cash causing liquidity around the world to cost more. With
liquidity evaporating, many leveraged investors were forced to liquidate
regardless of valuation conviction. Given the turmoil in the credit markets,
where even the most creditworthy counterparties were hesitant to lend even
overnight, the U.S. Federal Reserve first reduced its emergency discount window
rate, and then reduced its Federal Funds rate. Both rate reductions of 50 basis
points helped calm the marketplace as September ended. Although some fears have
receded, concerns over economic growth, reacceleration of inflation, and
monetary policy remain well entrenched.

Energy and material related names led the Fund's benchmark, the Russell 1000
Growth Index, as investors sought value in hard assets. Financials and consumer
cyclicals sectors were the worst performing sectors reflecting investors'
concerns over further deterioration of the housing sector and the strength of
consumer confidence.

During the reporting period, the Fund underperformed its benchmark in an up
market. Selection within the technology, consumer cyclicals, and
telecommunication sectors contributed positively to performance. Companies
differentiating themselves through cash generation continued to have positive
performance. This was particularly the case within technology and the
telecommunications sectors. Within consumer cyclicals, strong operating
efficiencies were rewarded throughout the period. Health care, information and
industrial sectors detracted from performance as oil services, drug, and
internet related companies lagged their respective benchmark groups.

Our approach involves the identification of those common stock attributes that
are rewarded in a given market environment. We seek to capture market themes
among equities by emphasizing the optimal combination of fundamentally based
characteristics to identify good stocks. In addition, we use a disciplined
construction process that provides a portfolio that is broadly diversified
across economic sectors.

Average annual total return reflects the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

                    Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

+  Expenses are equal to the Fund's annualized expense ratio of 0.95%,
   multiplied by the average account value over the period, multiplied by
   183/365 (to reflect the one-half year period).

                  Mellon Institutional Funds Investment Trust
                      Mellon Equity Large Cap Growth Fund

                         Notes to Financial Statements
- --------------------------------------------------------------------------------

(1)  Organization and 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
     Mellon Equity Large Cap Growth Fund (the "Fund"), which commenced operation
     on December 21, 2005, 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 large
     capitalization companies that have total market capitalizations within the
     range of capitalizations of the companies in the top 80% of the Russell
     1000 Growth Index at the time of purchase.

     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

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. Securities are valued at the last sale prices on the exchange or
     national securities market on which they are primarily traded. Securities
     not listed on an exchange or national securities market, or securities for
     which there were no reported transactions, are valued at the last
     calculated mean price (average of last bid and last offer). Securities that
     are fixed income securities, other than short-term instruments with less
     than sixty days remaining to maturity, for which accurate market prices are
     readily available, are valued at their current market value on the basis of
     quotations, which may be furnished by a pricing service or dealers in such
     securities. Securities (including illiquid securities) for which quotations
     are not readily available, or if such quotations do not accurately reflect
     fair value, are valued at their fair value as determined in good faith
     under consistently applied procedures under the general supervision of the
     Trustees. With respect to any portion of the Fund's assets that are
     invested in one or more open-end regulated investment companies ("RICs"),
     the Fund's net asset value ("NAV") will be calculated based upon the NAVs
     of such RICs.

     Exchange traded options and futures are valued at the settlement price
     determined by the relevant exchange. Non-exchange traded derivatives are
     normally valued on the basis of quotes obtained from brokers and dealers,
     including counterparties or pricing services.

     Short-term instruments with less than sixty days remaining to maturity 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 cost based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized cost does not represent fair value.

     B. Securities transactions and income

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

     C. Distributions to shareholders

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from 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 reclassifications, are primarily due
     to wash sales.

     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 (loss) and accumulated net
     realized gain (loss) on investments may include temporary book and tax
     basis differences which will be distributed in a subsequent period. Any
     taxable income or gain remaining at fiscal year end is distributed in the
     following year.

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

     D. Expenses

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

     E. Commitments and contingencies

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

     F. Affiliated issuers

     Affiliated issuers are investment companies advised by Mellon Equity
     Associates, LLP ("Mellon Equity"), a wholly-owned subsidiary of The Bank of
     New York Mellon Corporation ("BNY Mellon"), or its affiliates.

     G. New accounting requirements

     On September 20, 2006, the Financial Accounting Standards Board ("FASB")
     released Statement of Financial Accounting Standards No. 157 "Fair Value
     Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition
     of fair value, sets out a framework for measuring fair value, and requires
     additional disclosures about fair-value measurements. The application of
     FAS 157 is required for fiscal years beginning after November 15, 2007 and
     interim periods within those fiscal years. At this time, management is
     evaluating the implications of FAS 157 and its impact, if any, in the
     financial statements has not yet been determined.

(2)  Investment Advisory Fee and Other Transactions With Affiliates:

     The investment advisory fee paid to Mellon Equity for overall investment
     advisory, administrative services, and general office facilities, is paid
     monthly at the annual rate of 0.65% of the Fund's average daily net assets.
     Mellon Equity voluntarily agreed to limit the Fund's total annual operating
     expenses (excluding brokerage commissions, taxes and extraordinary
     expenses) to 0.95% of the Fund's average daily net assets for the year
     ended September 30, 2007. Pursuant to this agreement, for the year ended
     September 30, 2007, Mellon Equity voluntarily waived a portion of its
     investment advisory fee in the amount of $31,362 and reimbursed $84,532 of
     the Fund's operating expenses. This arrangement is voluntary and temporary
     and may be discontinued or revised by Mellon Equity at any time.

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
     subsidiary of BNY Mellon and an affiliate of Mellon Equity, to provide
     personnel and facilities to perform transfer agency and certain shareholder
     services for the Fund. For these services the Fund pays Dreyfus Transfer,
     Inc. a fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $6,119, for the year ended September 30, 2007.

     The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"),
     a wholly-owned subsidiary of BNY Mellon and an affiliate of Mellon Equity,
     to provide custody, administration and accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $44,535 for the year ended September 30,
     2007.

     The Trust also entered into an agreement with Mellon Bank to perform
     certain securities lending activities and to act as the Fund's lending
     agent. Mellon Bank receives an agreed upon percentage of the net lending
     revenues. Pursuant to this agreement, Mellon Bank earned $112 for the year
     ended September 30, 2007. See Note 6 for further details.

     The Trust entered into two separate agreements with The Bank of New York
     that enables the Fund, and other funds in the Trust, to borrow, in the
     aggregate, (i) up to $35 million from a committed line of credit and (ii)
     up to $15 million from an uncommitted line of credit. Interest is charged
     to each participating fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. The participating funds also
     pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
     uncommitted amounts and allocated ratably to the participating funds. In
     addition, a facility fee, computed at an annual rate of 0.060 of 1% on the
     committed amount, is allocated ratably among the participating funds at the
     end of each quarter. Pursuant to these agreements, the Fund was charged $72
     for the year ended September 30, 2007, which is included in miscellaneous
     expenses on the statement of operations. See Note 7 for further details.

                         Notes to Financial Statements
- --------------------------------------------------------------------------------

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended
     September 30, 2007, the Fund was charged $4,250, which amount is included
     in miscellaneous expenses in the statement of operations. No other
     director, officer or employee of Mellon Equity or its affiliates receives
     any compensation from the Trust or the Fund for serving as an officer or
     Trustee of the Trust. The Fund pays each Trustee who is not a director,
     officer or employee of Mellon Equity or its affiliates an annual fee and a
     per meeting fee as well as reimbursement for travel and out-of-pocket
     expenses. In addition, the Trust pays the legal fees for the independent
     counsel of the Trustees.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     year ended September 30, 2007, the Fund was not charged an administrative
     service fee by an affiliate of BNY Mellon.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of Mellon Equity, to provide
     printing and fulfillment services for the Fund. Pursuant to this agreement,
     the Fund was charged $1,171, which amount is included in miscellaneous
     expenses in the statement of operations, for the year ended September 30,
     2007.

     Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
     owned subsidiary of BNY Mellon and affiliate of Mellon Equity, replaced
     Mellon Funds Distributor, L.P. as the Fund's principal distributor.

     Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
     of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
     Mellon being the surviving entity of each merger.

(4)  Shares of Beneficial Interest:

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



                                                                  For the period

     At September 30, 2007, one shareholder of record (MBC Investments Corp., a
     wholly-owned subsidiary of BNY Mellon and an affiliate of Mellon Equity)
     held in the aggregate 96% of the total outstanding shares of the Fund.
     Investment activities of this shareholder could have a material impact on
     the Fund.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     30 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2007, the Fund did not
     assess any redemption fees.

                         Notes to Financial Statements
- --------------------------------------------------------------------------------

(5)  Federal Taxes:

     Each year, the Fund intends to qualify as a "regulated investment company"
     under Subchapter M of the Code. As such and by complying with the
     applicable provisions of the Code regarding the sources of its income, the
     timely distributions of its income to its shareholders, and the
     diversification of its assets, the Fund will not be subject to U.S. federal
     income tax on its investment company taxable income and net capital gain
     which are distributed to shareholders.

     In July 2006, FASB issued Interpretation No. 48, "Accounting for
     Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
     (the "Interpretation"). The Interpretation establishes for all entities,
     including pass-through entities such as the Fund, a minimum threshold for
     financial statement recognition of the benefit of positions taken in filing
     tax returns (including whether an entity is taxable in a particular
     jurisdiction), and requires certain expanded tax disclosures. Adoption of
     FIN 48 is required for fiscal years beginning after December 15, 2006 and
     is to be applied to all open tax years as of the effective date. At this
     time, management is evaluating the implications of FIN 48 and its impact on
     the financial statements has not yet been determined.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2007 were as follows:


                                                      
        Cost for federal income tax purposes             $2,819,264
                                                         ==========
        Gross unrealized appreciation                    $  442,041
        Gross unrealized depreciation                       (53,097)
                                                         ----------
        Net unrealized appreciation (depreciation)       $  388,944
                                                         ==========
        Undistributed ordinary income                    $  175,598
        Undistributed capital gains                         185,475
                                                         ----------

                                                         ==========


     The tax character of distributions paid during the fiscal years ended
     September 30, 2007 and September 30, 2006 was as follows:



                                                2007            2006

        Ordinary income                      $  20,067        $ 5,000
                                             =========        =======


(6)  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, 2007 and
     earned interest on the invested collateral of $3,252 of which $2,981 was
     rebated to borrowers or paid in fees. At September 30, 2007, the Fund had
     securities valued at $130,819 on loan. See Schedule of Investments for
     further detail on the security positions on loan and collateral held, of
     which $43,900 was collateralized with cash and $90,600 was collateralized
     with liquid securities.

(7)  Line of Credit:

     On behalf of the Fund, and other funds in the Trust, the Trust has access
     to a credit facility, which enables each fund to borrow, in the aggregate,
     up to $35 million under a committed line of credit and up to $15 million
     under an uncommitted line of credit.

     For the year ended September 30, 2007, the Fund had average borrowings
     outstanding of $42,750 for a total of eight days and incurred $55 of
     interest expense. At September 30, 2007, the Fund did not have a loan
     balance outstanding.

            Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------

     To the Trustees of Mellon Institutional Funds Investment Trust and
     Shareholders of Mellon Equity Large Cap Growth 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
     Equity Large Cap Growth Fund (the "Fund") at September 30, 2007, the
     results of its operations for the year then ended, and the changes in its
     net assets and the financial highlights for the year then ended and for the
     period from December 21, 2005 (commencement of operations) through
     September 30, 2006, in conformity with accounting principles generally
     accepted in the United States of America. These financial statements and
     financial highlights (hereafter referred to as "financial statements") are
     the responsibility of the Fund's management. Our responsibility is to
     express an opinion on these financial statements based on our audits. We
     conducted our audits of these financial statements in accordance with the
     standards of the Public Company Accounting Oversight Board (United States).
     Those standards require that we plan and perform the audit to obtain
     reasonable assurance about whether the financial statements are free of
     material misstatement. An audit includes examining, on a test basis,
     evidence supporting the amounts and disclosures in the financial
     statements, assessing the accounting principles used and significant
     estimates made by management, and evaluating the overall financial
     statement presentation. We believe that our audits, which included
     confirmation of securities at September 30, 2007 by correspondence with the
     custodian and brokers, provide a reasonable basis for our opinion.

          September 2007

          Dear Mellon Institutional Fund Shareholder:

          Enclosed you will find your Fund's annual report for the fiscal year
          ended September 30, 2007.

          The financial markets experienced a major bout of volatility in the
          summer stemming from two principal sources: troubles in the credit
          markets related to the difficulties experienced by mortgage securities
          backed by sub-prime loans, and the high degree of leverage employed by
          many hedge funds, whose impact on the markets has swollen
          significantly over the past decade. From its peak of over 1550 in
          mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
          close the quarter at just under its peak for the 12-month period,
          resulting in an 11.8% return over that period. Part of the rebound was
          due to the September 18 decision by the U.S. Federal Reserve Board to
          cut the Federal Funds rate by 50 basis points to 4.75%. This ended a
          string of nine consecutive meetings in which the Fed left rates
          unchanged. The reduction was 25 basis points greater than anticipated,
          driven by the Fed's concerns over the housing recession and tighter
          credit availability.

          Credit markets responded to the sub-prime troubles with a broad-based
          flight to quality as investors fled to short-term Treasury securities.
          One result was a significant steepening of the yield curve, as the
          yield on the 2-year Treasury note fell 86 basis points to 3.98%, while
          the 30-year Treasury bond yield dropped just 25 basis points to 4.84%.
          In a dramatic re-pricing of risk, spreads widened in the corporate
          bond sector compared to Treasury issues, which has the effect of
          making corporate borrowing more expensive. In another indication of
          just how disruptive this period was in the credit markets, even some
          issuers of commercial paper - typically viewed as the safest segment
          of the corporate market - had trouble issuing or rolling over their
          issues.

          While liquidity has slowly returned to the bond markets in general,
          the mortgage sector clearly has been shaken, and this will likely
          exacerbate the housing recession as financing becomes more expensive.
          In the view of some, the likelihood of a broader U.S. recession has
          become greater. Our view is that a period of diminished growth -
          around 2% GDP growth in 2008 vs. the 2.5% long-term trend - is more
          likely. We see U.S. exports boosted by the weaker dollar, multi-year
          global economic expansion and monetary growth, and high corporate
          profitability - especially for multinational franchises - as being
          positives that partially offset the drag of the housing sector and
          lower consumption.

          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,
          Barbara McCann
          President

                       Management Discussion and Analysis
- -------------------------------------------------------------------------------

          Over the past year, equity markets have faced many negative
          crosscurrents, such as rising energy prices and turmoil in the credit
          markets. In spite of these negative influences, equity markets posted
          positive returns over the past year, though not without a noticeable
          market decline in mid to late summer. At the very moment it appeared
          that the equity markets were set for a meaningful decline, the U.S.
          Federal Reserve changed course and cut key interest rates. Upon this
          news, markets rallied in September, and thus provided attractive total
          returns for the year under review. Within the context of such a
          turbulent market, it is not surprising that generally speaking, larger
          capitalization stocks outperformed smaller capitalization issues, as
          investors searched for stability. While micro cap stocks provided a
          positive absolute return over the past year, it is also not surprising
          that this slice of the equity marketplace was also the weakest
          performing sector, when compared to other equity capitalization
          classifications.

          For the one-year period ended September 30, 2007, the Fund provided a
          total return of 8.85% as compared to 9.51% for the Dow Jones Wilshire
          Micro Cap Index, the Fund's benchmark. While we were pleased that the
          Fund achieved a positive absolute return, we were nonetheless
          disappointed that the return was modestly below that of the benchmark.
          Our goal remains to generate investment returns that exceed our
          performance benchmark. We manage the Fund using a quantitative
          valuation model along with a sector neutral approach to stock
          selection based on the performance benchmark. Thus individual stock
          selection within each economic sector is the primary engine that
          drives investment performance.

          Our stock selections within the health care and energy sectors were
          especially rewarding. Within the health care sector, we experienced
          beneficial stock selection among bio-technology and pharmaceutical
          companies. Among our bio-technology holdings, we achieved positive
          results both through owning a company that was subject to a very
          attractive takeover offer, to owning issues that had very positive new
          product announcements over the past year. Among our pharmaceutical
          holdings, companies with products serving such diverse markets as
          cardiovascular health to veterinarian/animal health also had a
          positive impact upon relative performance. Within the energy related
          sector, some of our investments among oil exploration companies
          contributed positively to performance. As for negative influences, we
          had disappointing stock selections among financial services companies,
          especially among banks and thrift institutions. This group appeared to
          be under pressure as smaller and more consumer oriented financial
          institutions faced an environment of generally rising interest rates,
          and growing consumer anxiety about their personal economic condition.
          Such a mix caused many investors to become concerned about the future
          business trends for these smaller financial organizations. We also had
          some disappointing results among industrial services and freight
          companies. These types of firms tend to be more economically
          sensitive, and appeared to be under pressure again based upon an
          uncertain interest rate and economic outlook.

          In closing, we have just been through a fairly uncertain economic
          environment, with issues such as rising energy prices and the subprime
          credit market worries causing a high level of investor anxiety. In
          spite of these negatives, the microcap sector of the equity market
          generated competitive returns over the past year. Thus, we remain
          convinced that this capitalization sector continues to provide
          attractive and very dynamic investment opportunities, and should be a
          portion of a well-diversified equity portfolio.

Average annual total return reflects the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

                     Shareholder Expense Example (Unaudited)
- -------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

  multiplied by the average account value over the period, multiplied by
  183/365 (to reflect the one-half year period).

                  Mellon Institutional Funds Investment Trust
                          Mellon Equity Micro Cap Fund


                          Notes to Financial Statements
- -------------------------------------------------------------------------------
(1)  Organization and 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
     Mellon Equity Micro Cap Fund (the "Fund"), which commenced operations on
     May 1, 2006, 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 micro cap
     U.S. companies with total market capitalizations equal to or less than $1
     billion at the time of investment.

     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

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. Securities are valued at the last sale prices on the exchange or
     national securities market on which they are primarily traded. Securities
     not listed on an exchange or national securities market, or securities for
     which there were no reported transactions, are valued at the last
     calculated mean price (average of last bid and last offer). Securities that
     are fixed income securities, other than short-term instruments with less
     than sixty days remaining to maturity, for which accurate market prices are
     readily available, are valued at their current market value on the basis of
     quotations, which may be furnished by a pricing service or dealers in such
     securities. Securities (including illiquid securities) for which quotations
     are not readily available, or if such quotations do not accurately reflect
     fair value, are valued at their fair value as determined in good faith
     under consistently applied procedures under the general supervision of the
     Trustees. With respect to any portion of the Fund's assets that are
     invested in one or more open-end regulated investment companies ("RICs"),
     the Fund's net asset value ("NAV") will be calculated based upon the NAVs
     of such RICs.

     Exchange traded options and futures are valued at the settlement price
     determined by the relevant exchange. Non-exchange traded derivatives are
     normally valued on the basis of quotes obtained from brokers and dealers,
     including counterparties or pricing services.Short-term instruments with
     less than sixty days remaining to maturity 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 cost based upon the value on such date
     unless the Trustees determine during such sixty-day period that amortized
     cost does not represent fair value.

     B. Securities transactions and income

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

     C. Distributions to shareholders

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from 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 reclassifications, are primarily due to losses deferred
     due to wash sales.

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

                          Notes to Financial Statements
- -------------------------------------------------------------------------------
     D. Expenses

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

     E. Commitments and contingencies

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

     F. Affiliated issuers

     Affiliated issuers are investment companies advised by Mellon Equity
     Associates, LLP ("Mellon Equity"), a wholly-owned subsidiary of The Bank of
     New York Mellon Corporation ("BNY Mellon"), or its affiliates.

     G. New accounting requirements

     On September 20, 2006, the Financial Accounting Standards Board ("FASB")
     released Statement of Financial Accounting Standards No. 157 "Fair Value
     Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition
     of fair value, sets out a framework for measuring fair value, and requires
     additional disclosures about fair-value measurements. The application of
     FAS 157 is required for fiscal years beginning after November 15, 2007 and
     interim periods within those fiscal years. At this time, management is
     evaluating the implications of FAS 157 and its impact, if any, in the
     financial statements has not yet been determined.

(2)  Investment Advisory Fee and Other Transactions With Affiliates:

     The investment advisory fee paid to Mellon Equity for overall investment
     advisory, administrative services, and general office facilities, is paid
     monthly at the annual rate of 1.00% of the Fund's average daily net assets.
     Mellon Equity voluntarily agreed to limit the Fund's total annual operating
     expenses (excluding brokerage commissions, taxes and extraordinary
     expenses) to 1.35% of the Fund's average daily net assets for the year
     ended September 30, 2007. Pursuant to this arrangement, for the year ended
     September 30, 2007, Mellon Equity voluntarily waived a portion of its
     investment advisory fee in the amount of $95,995. This arrangement is
     voluntary and temporary and may be discontinued or revised by Mellon Equity
     at any time.

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
     subsidiary of BNY Mellon and an affiliate of Mellon Equity, to provide
     personnel and facilities to perform transfer agency and certain shareholder
     services for the Fund. For these services the Fund pays Dreyfus Transfer,
     Inc. a fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $8,331, for the year ended September 30, 2007.

     The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"),
     a wholly-owned subsidiary of BNY Mellon and an affiliate of Mellon Equity,
     to provide custody, administration and accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $50,317 for the year ended September 30,
     2007.

     The Trust also entered into an agreement with Mellon Bank to perform
     certain securities lending activities and to act as the Fund's lending
     agent. Mellon Bank receives an agreed upon percentage of the net lending
     revenues. Pursuant to this agreement, Mellon Bank earned $5,659 for the
     year ended September 30, 2007. See Note 6 for further details.

     The Trust entered into two separate agreements with The Bank of New York
     that enables the Fund, and other funds in the Trust, to borrow, in the
     aggregate, (i) up to $35 million from a committed line of credit and (ii)
     up to $15 million from an uncommitted line of credit. Interest is charged
     to each participating fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. The participating funds also
     pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
     uncommitted amounts and allocated ratably to the participating funds. In
     addition, a facility fee, computed at an annual rate of 0.060 of 1% on the
     committed amount, is allocated ratably among the participating funds at the
     end of each quarter. Pursuant to these agreements, the Fund was charged $71
     for the year ended September 30, 2007, which amount is included in
     miscellaneous expenses on the statement of operations. See Note 7 for
     further details.

                          Notes to Financial Statements
- --------------------------------------------------------------------------------
     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended
     September 30, 2007, the Fund was charged $4,250, which amount is included
     in miscellaneous expenses in the statement of operations. No other
     director, officer or employee of Mellon Equity or its affiliates receives
     any compensation from the Trust or the Fund for serving as an officer or
     Trustee of the Trust. The Fund pays each Trustee who is not a director,
     officer or employee of Mellon Equity or its affiliates an annual fee and a
     per meeting fee as well as reimbursement for travel and out-of-pocket
     expenses. In addition, the Trust pays the legal fees for the independent
     counsel of the Trustees.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of Mellon Equity, to provide
     printing and fulfillment services for the Fund. Pursuant to this agreement,
     the Fund was charged $1,241, which amount is included in miscellaneous
     expenses in the statement of operations, for the year ended September 30,
     2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     year ended September 30, 2007, the Fund was not charged an administrative
     service fee by any BNY Mellon affiliates.

     Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
     owned subsidiary of BNY Mellon and affiliate of Mellon Equity, replaced
     Mellon Funds Distributor, L.P. as the Fund's principal distributor.

     Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
     of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
     Mellon being the surviving entity of each merger.

(4)  Shares of Beneficial Interest:

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



                                                              For the period
                                                               May 1, 2006

     At September 30, 2007, two shareholders of record (including MBC
     Investments Corp., a wholly-owned subsidiary of BNY Mellon and an affiliate
     of Mellon Equity which holds approximately 52%) held in the aggregate 98.8%
     of the total outstanding shares of the Fund. Investment activities of these
     shareholders could have a material impact on the Fund.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     30 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2007, the Fund did not
     assess any redemption fees.

                          Notes to Financial Statements
- -------------------------------------------------------------------------------
(5)  Federal Taxes:

     Each year, the Fund intends to qualify as a "regulated investment company"
     under Subchapter M of the Code. As such and by complying with the
     applicable provisions of the Code regarding the sources of its income, the
     timely distributions of its income to its shareholders, and the
     diversification of its assets, the Fund will not be subject to U.S. federal
     income tax on its investment company taxable income and net capital gain
     which are distributed to shareholders.

     In July 2006, FASB issued Interpretation No. 48, "Accounting for
     Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
     (the "Interpretation"). The Interpretation establishes for all entities,
     including pass-through entities such as the Fund, a minimum threshold for
     financial statement recognition of the benefit of positions taken in filing
     tax returns (including whether an entity is taxable in a particular
     jurisdiction), and requires certain expanded tax disclosures. Adoption of
     FIN 48 is required for fiscal years beginning after December 15, 2006 and
     is to be applied to all open tax years as of the effective date. At this
     time, management is evaluating the implication of FIN 48 and its impact in
     the financial statements has not yet been determined.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2007 were as follows:

(6)  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, 2007 and
     earned interest on the invested collateral of $2,579,964 of which
     $2,563,690 was rebated to borrowers or paid in fees. At September 30, 2007,
     the Fund had securities valued at $1,421,255 on loan of which $1,525,413
     was collateralized with cash and $35,750 was collateralized with highly
     liquid securities. See Schedule of Investments for further detail on the
     security positions on loan and collateral held.

(7)  Line of Credit:

     On behalf of the Fund and other funds in the Trust, the Trust has access to
     a credit facility, which enables each fund to borrow, in the aggregate, up
     to $35 million under a committed line of credit and up to $15 million under
     an uncommitted line of credit. For the year ended September 30, 2007, the
     Fund had average borrowings outstanding of $1,000 for a total of one days
     and incurred $0 of interest expense. At September 30, 2007, the Fund did
     not have a loan balance outstanding.

            Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------------------------------

     To the Trustees of Mellon Institutional Funds Investment Trust and
     Shareholders of Mellon Equity Micro Cap 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
     Equity Micro Cap Fund (the "Fund") at September 30, 2007, the results of
     its operations for the year then ended, and the change in its net assets
     and the financial highlights for the year then ended and for the period
     from May 1, 2006 (commencement of operations) through September 30, 2006,
     in conformity with accounting principles generally accepted in the United
     States of America. These financial statements and financial highlights
     (hereafter referred to as "financial statements") are the responsibility of
     the Fund's management. Our responsibility is to express an opinion on these
     financial statements based on our audits. We conducted our audits of these
     financial statements in accordance with the standards of the Public Company
     Accounting Oversight Board (United States). Those standards require that we
     plan and perform the audit to obtain reasonable assurance about whether the
     financial statements are free of material misstatement. An audit includes
     examining, on a test basis, evidence supporting the amounts and disclosures
     in the financial statements, assessing the accounting principles used and
     significant estimates made by management, and evaluating the overall
     financial statement presentation. We believe that our audits, which
     included confirmation of securities at September 30, 2007 by correspondence
     with the custodian and brokers, provide a reasonable basis for our opinion.

MELLON INSTITUTIONAL FUNDS


September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

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,
Barbara McCann
President

                        Newton International Equity Fund

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------


Newton's investment philosophy is structured around the central tenet of our
business: no company, market or economy can be considered in isolation; each
must be understood in a global context.

We believe that, in a rapidly shrinking world, we can properly evaluate the
prospects for equities only by understanding events, trends and competitive
pressures globally. We also believe that a geographically constrained
perspective to stock selection limits a portfolio manager's ability to identify
and invest in the strongest companies and does not provide for sufficient
exposure to deep, long-term trends in economies.

The roots of the current equity market turmoil have been a concern of Newton for
some time. The very low level of interest rates for much of this decade and
problems of the post dot.com bubble have engendered a rapid acceleration in
consumer lending in the US and UK against a backdrop of soaring house prices and
a boom in Merger & Acquisition (M&A) activity, fed by debt and exemplified by
the prominence of private equity. With banks and insurers from Germany to
Singapore admitting exposure to potentially worthless US mortgage-backed
securities, markets are understandably nervous.

As banks tighten lending requirements we may see a more significant slow-down in
the US and this could have a negative impact on the rest of the world. However,
competing trends such as the urbanization and industrialization of Asia may
provide some offset.

Although global equity markets began the period with solid gains (on the back of
better data than expected from the US), they went through several changes of
fortune during the twelve months to September 30, 2007. Some of the factors
influencing these swings were:

o  aggressive rhetoric in China from the government, prompting fears that the
   authorities intended to curtail recent dramatic share price appreciation and
   introduce a sharper capital gains tax regime;

o  the acute deterioration in the US sub-prime mortgage market, followed by the
   collapse of a number of sub-prime finance providers;

o  the ever-growing pipeline of M&A transactions, ensuring strong performance
   from Continental Europe;

o  the yen's devaluation against a broad range of currencies, which proved to be
   a key determinant of performance in Japan;

o  a sharp sell-off in Thailand following its Central Bank's bungled attempt to
   instigate exchange controls in order to curb the baht's appreciation;

o  a rise in the Brazilian credit rating to one level below investment grade;

o  a significant volatility in equity markets in the three months to September
   2007, as one of the consequences of the US sub-prime mortgage crisis.

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------


Many of these events played particularly to our key long-term themes(1) of
'Global Realignment,' 'Debt & Credit' and 'Developing Economies.'

For the twelve months to September 30, 2007, the Fund produced a return of 26.9%
as compared to a return of 24.9% for its benchmark, the MSCI EAFE Index. Over
the period outperformance relative to the benchmark was achieved primarily in
the Industrials, Energy and Financials sectors, while poor relative performance
was seen in the Healthcare and Information Technology sectors.

In sector terms, Industrials was the top performer for the Fund: our 'Energy
Supply' theme was a primary driver for activity in this sector during 2007. We
remain positive on Telecoms, where we continue to see major opportunities for
expansion and distribution in the developing world. The sector made a good
contribution to the overall performance of the Fund during the year. The two
worst-performing areas over the period were Healthcare and Information
Technology.

During the months leading up to September 2007 we saw continuing credit fears
and concerns over a slowing US economy leading indices down before interest rate
cuts helped them rebound strongly. Prior to these rate cuts, we had seen a
concentrated period of heavy selling across asset classes in mid-August. This
became indiscriminate in some cases, in our view, and we therefore added to some
positions that we expect to be key beneficiaries of our 'Global Realignment'
theme. All of these stocks were sold down in the markets as investors reduced
their exposure to perceived 'risky' areas. We view this as ironic: the US dollar
appreciated at this time as monies were repatriated to the economy most exposed
to the catalyst of the market's concerns - the US itself.

We continue to believe that the well-documented sub-prime and credit issues will
take some time to play out. There is little clarity as to where the worst of the
debt sits as much is wrapped up in larger vehicles, and neither the investment
banks nor underlying investors can know with confidence to what extent they are
exposed. This major 'Debt and Credit' event reinforces our caution on bank
stocks: Australian and UK domestic banking exposure remains zero.

This said, we contend that the rest of the world will be better insulated from
US economic weakness as decoupling continues. Our macroeconomic outlook for Asia
ex-Japan, Continental Europe and the developing markets remains constructive.

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------


Over the next few months we expect the market to begin to differentiate more
rationally between the likely winners and losers, providing further opportunity
to increase favoured holdings. We do not see the recent turmoil greatly changing
our key themes of 'Debt & Credit', 'Energy Supply' and 'Global Realignment' and
so continue to represent these views within the Fund.

   o  Global Realignment - The western industrialised nations dominate the
      world's GDP, wealth, consumption and market capitalisation in US dollar
      terms, as well as consuming the lion's share of natural resources. The
      stronger growth and increasing economic influence of the developing world
      will progressively challenge this position. Some realignment over time is
      inevitable; how it occurs will be crucially important to the longer term
      global economic outlook.

   o  Debt & Credit - The era of disinflation has fostered a supercycle of
      credit growth in many of the developed economies. In recent years the pace
      of credit expansion has accelerated in response to global financial
      deregulation, relatively loose monetary policy and innovations in
      structured finance. The resulting high level of corporate and individual
      leverage in these economies is in stark contrast to that prevailing in the
      developing world where savings rates remain high.

   o  Energy Supply - Forecasts of strong developing world growth together with
      increases in per capita energy usage point to continued strong demand for
      petroleum products. When combined with uncertainties over supply, this
      implies a structurally high real oil price. This theme has broad
      implications across sectors and economies, particularly in the light of
      measures to tackle climate change.

   o  Developing Economies - The developing economies are increasingly fully
      engaged in the world trading system. Their influence on the global
      economic cycle is growing and they are on an apparent convergence course
      with the industrialised world. This secular trend will however be subject
      to significant cyclical influences particularly from the larger economies,
      such as China, and frictions regarding trade policies.

Average annual total return reflects the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

                     Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------


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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

   multiplied by the average account value over the period, multiplied by
   183/365 (to reflect the one-half year period).

                          Notes to Financial Statements
- --------------------------------------------------------------------------------


(1)   Organization and 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 Newton International Equity Fund (the "Fund"), which
      commenced operation on December 21, 2005, 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 common stocks or securities
      convertible into common stocks (such as convertible preferred stocks,
      warrants and convertible bonds) of foreign companies and depositary
      receipts evidencing ownership in such securities. At least 75% of the
      Fund's net assets will be invested in countries represented in the Morgan
      Stanley Capital International Europe, Australasia and the Far East (MSCI
      EAFE) Index. The Fund may invest up to 20% of its assets in emerging
      market countries.

      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

      Fund shares are valued as of the close of regular trading (normally 4:00
      p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
      is open. Securities are valued at the last sale prices on the exchange or
      national securities market on which they are primarily traded. Securities
      not listed on an exchange or national securities market, or securities for
      which there were no reported transactions, are valued at the last
      calculated mean price (average of last bid and last offer). Securities
      that are fixed income securities, other than short-term instruments with
      less than sixty days remaining to maturity, for which accurate market
      prices are readily available, are valued at their current market value on
      the basis of quotations, which may be furnished by a pricing service or
      dealers in such securities. Securities (including illiquid securities) for
      which quotations are not readily available, or if such quotations do not
      accurately reflect fair value, are valued at their fair value as
      determined in good faith under consistently applied procedures under the
      general supervision of the Trustees. With respect to any portion of the
      Fund's assets that are invested in one or more open-end regulated
      investment companies ("RICs"), the Fund's net asset value ("NAV") will be
      calculated based upon the NAVs of such RICs.

      Exchange traded options and futures are valued at the settlement price
      determined by the relevant exchange. Non-exchange traded derivatives are
      normally valued on the basis of quotes obtained from brokers and dealers,
      including counterparties or pricing services.

      Because foreign markets may be open at different times than the NYSE, the
      value of the Fund's shares may change on days when shareholders are not
      able to buy or sell them. Many securities markets and exchanges outside
      the U.S. close prior to the close of the NYSE and therefore the closing
      prices for securities in such markets or on such exchanges may not fully
      reflect the events that occur after such close but before the close of the
      NYSE.

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

      Short-term instruments with less than sixty days remaining to maturity 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 cost based upon the
      value on such date unless the Trustees determine during such sixty-day
      period that amortized cost does not represent fair value.

      B. Securities transactions and income

      Securities transactions are recorded as of trade date. Interest income is
      determined on the basis of coupon interest accrued, adjusted for accretion
      of discount or amortization of premium using the yield-to-maturity method
      on debt securities with greater than sixty days remaining to maturity.
      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.

                          Notes to Financial Statements
- --------------------------------------------------------------------------------


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

      C. Distributions to shareholders

      Distributions to shareholders are recorded on the ex-dividend date. The
      Fund's distributions from 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 reclassifications, are primarily due to differing
      treatments for foreign currency transactions and losses deferred due to
      wash sales and passive foreign investment companies (PFIC).

      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 (loss) and accumulated net
      realized gain (loss) on investments may include temporary book and tax
      basis differences which will be distributed in a subsequent period. Any
      taxable income or gain remaining at fiscal year end will be distributed in
      the following year.

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

      D. Expenses

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

      E. Foreign currency transactions

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

      F. Foreign investment risk

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

      G. Commitments and contingencies

      In the normal course of business, the 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.

      H. Affiliated issuers

      Affiliated issuers are investment companies advised by Newton Capital
      Management Ltd. ("Newton"), a wholly-owned subsidiary of The Bank of New
      York Mellon Corporation ("BNY Mellon"), or its affiliates.

      I. New accounting requirements

      The Financial Accounting Standards Board ("FASB") released Statement of
      Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS
      157"). FAS 157 establishes an authoritative definition of fair value, sets
      out a framework for measuring fair value, and requires additional
      disclosures about fair-value measurements. The application of FAS 157 is
      required for fiscal years beginning after November 15, 2007 and interim
      periods within those fiscal years. At this time, management is evaluating
      the implications of FAS 157 and its impact, if any, in the financial
      statements has not yet been determined.

(2)   Investment Advisory Fee and Other Transactions With Affiliates:

      The investment advisory fee paid to Newton for overall investment advisory
      and administrative services, and general office facilities, is paid
      monthly at the annual rate of 0.80% of the Fund's average daily net
      assets. Newton voluntarily agreed to limit the Fund's total annual
      operating expenses (excluding brokerage commissions, taxes and
      extraordinary expenses) to 1.15% of the Fund's average daily net assets
      for the year ended September 30, 2007. Pursuant to this agreement, for the
      year ended September 30, 2007, Newton voluntarily waived a portion of its
      investment advisory fee in the amount of $91,606. This arrangement is
      voluntary and temporary and may be discontinued or revised by Newton at
      any time.

      The Trust entered into an agreement with Dreyfus Transfer, Inc., a
      wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
      subsidiary of BNY Mellon and an affiliate of Newton, to provide personnel
      and facilities to perform transfer agency and certain shareholder services
      for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a
      fixed fee plus per account and transaction based fees, as well as,
      out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
      $6,630 for the year ended September 30, 2007.

      The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon
      Bank"), a wholly-owned subsidiary of BNY Mellon and an affiliate of
      Newton, to provide custody, administration and accounting services for the
      Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset
      and transaction based fees, as well as out-of-pocket expenses. Pursuant to
      this agreement, the Fund was charged $128,578 for the year ended September
      30, 2007.

      The Trust entered into two separate agreements with The Bank of New York
      that enables the Fund, and other funds in the Trust, to borrow, in the
      aggregate, (i) up to $35 million from a committed line of credit and (ii)
      up to $15 million from an uncommitted line of credit. Interest is charged
      to each participating fund based on its borrowings at a rate equal to the
      Federal Funds effective rate plus 1/2 of 1%. The participating funds also
      pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
      uncommitted amounts and allocated ratably to the participating funds. In
      addition, a facility fee, computed at an annual rate of 0.060 of 1% on the
      committed amount, is allocated ratably among the participating funds at
      the end of each quarter. Pursuant to these agreements, the Fund was
      charged $2,780 for the year ended September 30, 2007, which amount is
      included in miscellaneous expenses on the statement of operations. See
      Note 7 for further details.

      The Trust reimburses BNY Mellon Asset Management for a portion of the
      salary of the Trust's Chief Compliance Officer. For the year ended
      September 30, 2007, the Fund was charged $4,250, which amount is included
      in miscellaneous expenses in the statement of operations. No other
      director, officer or employee of Newton or its affiliates receives any
      compensation from the Trust or the Fund for serving as an officer or
      Trustee of the Trust. The Fund pays each Trustee who is not a director,
      officer or employee of Newton or its affiliates an annual fee and a per
      meeting fee as well as reimbursement for travel and out-of-pocket
      expenses. In addition, the Trust pays the legal fees for the independent
      counsel of the Trustees.

      The Trust has contracted Mellon Investor Services LLC, a wholly owned
      subsidiary of BNY Mellon and an affiliate of Newton, to provide printing
      and fulfillment services for the Fund. Pursuant to this agreement, the
      Fund was charged $1,344, which amount is included in miscellaneous
      expenses in the statement of operations, for the year ended September 30,
      2007.

      The Fund may pay administrative service fees. These fees are paid to
      affiliated or unaffiliated retirement plans, omnibus accounts and platform
      administrators and other entities ("Plan Administrators") that provide
      record keeping and/or other administrative support services to accounts,
      retirement plans and their participants. As compensation for such
      services, the Fund may pay each Plan Administrator an administrative
      service fee in an amount of up to 0.15% (on an annualized basis) of the
      Fund's average daily net assets attributable to Fund shares that are held
      in accounts serviced by such Plan Administrator. The Fund's adviser or its
      affiliates may pay additional compensation from their own resources to
      Plan

      Administrators and other entities for administrative services, as well as
      in consideration of marketing or other distribution-related services.
      These payments may provide an incentive for these entities to actively
      promote the Fund or cooperate with the distributor's promotional efforts.
      For the year ended September 30, 2007, the Fund was not charged an
      administrative service fee by an affiliate of BNY Mellon.

      Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
      owned subsidiary of BNY Mellon and affiliate of Newton, replaced Mellon
      Funds Distributor, L.P. as the Fund's principal distributor.

      Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
      of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
      Mellon being the surviving entity of each merger.

(3)   Purchases and Sales of Investments:

      Purchases and proceeds from sales of investments, other than short-term
      obligations, for the year ended September 30, 2007 were as follows:



                                                                                Purchases                      Sales

(4)   Shares of Beneficial Interest:

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



                                                                                                           For the period

                                                                              September 30, 2007          September 30, 2006

      At September 30, 2007, three shareholders of record, in the aggregate held
      approximately 97.2% of the total outstanding shares of the Fund.
      Investment activities of these shareholders could have a material impact
      on the Fund.

      The Fund imposes a redemption fee of 2% of the net asset value of the
      shares, with certain exceptions, which are redeemed or exchanged less than
      30 days from the day of their purchase. The redemption fee is paid
      directly to the Fund, and is designed to offset brokerage commissions,
      market impact, and other costs associated with short-term trading in the
      Fund. The fee does not apply to shares that were acquired through
      reinvestment of distributions. For the year ended September 30, 2007, the
      Fund did not assess any redemption fees.

(5)   Federal Taxes:

      Each year, the Fund intends to qualify as a "regulated investment company"
      under Subchapter M of the Code. As such and by complying with the
      applicable provisions of the Code regarding the sources of its income, the
      timely distributions of its income to its shareholders, and the
      diversification of its assets, the Fund will not be subject to U.S.
      federal income tax on its investment company taxable income and net
      capital gain which are distributed to shareholders.

      FASB issued Interpretation No. 48, "Accounting for Uncertainty in Income
      Taxes - an Interpretation of FASB Statement No. 109" (the
      "Interpretation"). The Interpretation establishes for all entities,
      including pass-through entities such as the Fund, a minimum threshold for
      financial statement recognition of the benefit of positions taken in
      filing tax returns (including whether an entity is taxable in a particular
      jurisdiction), and requires certain expanded tax disclosures. Adoption of
      FIN 48 is required for fiscal years beginning after December 15, 2006 and
      is to be applied to all open tax years as of the effective date. At this
      time, management is evaluating the implication of FIN 48 and its impact in
      the financial statements has not yet been determined.

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

      Forward Foreign Currency Exchange Contracts

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

      At September 30, 2007, the Fund held forward foreign currency exchange
      contracts. See Schedule of Investments for further details.

(7)   Line of Credit:

            Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------


To the Trustees of Mellon Institutional Funds Investment Trust and Shareholders
of Newton International 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 Newton International Equity Fund
(the "Fund") at September 30, 2007, the results of its operations for the year
then ended, and the changes in its net assets and the financial highlights for
the year then ended and for the period from December 21, 2005 (commencement of
operations) to September 30, 2006, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2007 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

MELLON INSTITUTIONAL FUNDS

     September 2007

     Dear Mellon Institutional Fund Shareholder:

     Enclosed you will find your Fund's annual report for the fiscal year ended
     September 30, 2007.

     The financial markets experienced a major bout of volatility in the summer
     stemming from two principal sources: troubles in the credit markets related
     to the difficulties experienced by mortgage securities backed by sub-prime
     loans, and the high degree of leverage employed by many hedge funds, whose
     impact on the markets has swollen significantly over the past decade. From
     its peak of over 1550 in mid-July, the S&P 500 dropped by about 6.5%,
     before rebounding to close the quarter at just under its peak for the
     12-month period, resulting in an 11.8% return over that period. Part of the
     rebound was due to the September 18 decision by the U.S. Federal Reserve
     Board to cut the Federal Funds rate by 50 basis points to 4.75%. This ended
     a string of nine consecutive meetings in which the Fed left rates
     unchanged. The reduction was 25 basis points greater than anticipated,
     driven by the Fed's concerns over the housing recession and tighter credit
     availability.

     Credit markets responded to the sub-prime troubles with a broad-based
     flight to quality as investors fled to short-term Treasury securities. One
     result was a significant steepening of the yield curve, as the yield on the
     2-year Treasury note fell 86 basis points to 3.98%, while the 30-year
     Treasury bond yield dropped just 25 basis points to 4.84%. In a dramatic
     re-pricing of risk, spreads widened in the corporate bond sector compared
     to Treasury issues, which has the effect of making corporate borrowing more
     expensive. In another indication of just how disruptive this period was in
     the credit markets, even some issuers of commercial paper - typically
     viewed as the safest segment of the corporate market - had trouble issuing
     or rolling over their issues.

     While liquidity has slowly returned to the bond markets in general, the
     mortgage sector clearly has been shaken, and this will likely exacerbate
     the housing recession as financing becomes more expensive. In the view of
     some, the likelihood of a broader U.S. recession has become greater. Our
     view is that a period of diminished growth - around 2% GDP growth in 2008
     vs. the 2.5% long-term trend - is more likely. We see U.S. exports boosted
     by the weaker dollar, multi-year global economic expansion and monetary
     growth, and high corporate profitability - especially for multinational
     franchises - as being positives that partially offset the drag of the
     housing sector and lower consumption.

     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,
     Barbara McCann
     President

                Standish Mellon Intermediate Tax Exempt Bond Fund

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

For the year ended September 30, 2007, the Standish Mellon Intermediate Tax
Exempt Bond Fund produced a total return after expenses of 3.26%. This result
trailed the benchmark performance index (Lehman Brothers Municipal 3-5-7-10 Year
Municipal Bond Index) return of 3.73%.

Tax-exempt interest rates changed only modestly during the last 12 months in
spite of highly visible turmoil from subprime mortgages, a midsummer contraction
of bond market liquidity and a half-point cut by the U.S. Federal Reserve in a
key overnight interest rate.

In the widening credit turmoil that roiled worldwide bond markets this summer,
investors fled risky assets for the safe haven of government bonds and notes. A
repricing of risk in July and August caused underperformance among many of the
income-oriented municipal revenue bond sectors which had consistently produced
excess returns over the last few years. Weightings in hospitals and housing
detracted from relative returns as investors abandoned those sectors in favor of
triple-A rated government-backed pre-refunded bonds. In addition, tax-exempt
bonds tied to corporations, particularly pre-paid natural gas and tobacco
securitization bonds, traded off in concert with trends among corporate bonds in
the taxable markets.

After another year of steady ratings upgrades, we believe municipal credit
quality is leveling out, albeit at a very high level. Average credit quality
among intermediate municipals is double-A. The Fund established a position in
bonds issued by the Commonwealth of Puerto Rico, which benefited during the
period from improving creditworthiness and strengthened financial management.

While U.S. gross domestic product may slow to below trend over the next year, we
believe that healthy corporate balance sheets, higher government spending,
export growth and income expansion should all help stave off recession. The
continuing downturn in housing and spreading financial contagion from subprime
mortgages may force the Federal Reserve to lower short-term interest rates again
by early 2008. Inflation does not appear to be a problem, which relieves upward
pressures on longer-term rates. Amidst heightened credit market volatility, the
Fund continues to emphasize high credit quality and a neutral interest rate
posture. As we write this, municipal bonds are priced attractively relative to
Treasury securities, producing a substantial after-tax yield advantage for
shareholders in all but the lowest federal tax brackets. In addition, the 2001
and 2003 tax cuts are set to expire in 2010, making tax-exempt bonds potentially
more valuable in coming years.

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

Sincerely,

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

                Standish Mellon Intermediate Tax Exempt Bond Fund

                    Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

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

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

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

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

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

(1)  Organization and 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 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
     shareholders' capital. The Fund seeks to achieve its objective by
     investing, under normal circumstances, at least 80% of net assets in tax
     exempt municipal securities issued by states, territories, and possessions
     of the United States, the District of Columbia and their political
     subdivisions, agencies and instrumentalities.

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

     A. Investment security valuations

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. Tax-exempt bonds and notes are priced at market on the basis of
     valuations furnished by an independent pricing service or dealers, approved
     by the Trustees. Such services or dealers determine valuations for normal
     institutional-size trading units of such securities using methods based on
     market transactions for comparable securities and various relationships,
     generally recognized by institutional traders, between securities.
     Securities (including illiquid securities) for which quotations are not
     readily available, or if such quotations do not accurately reflect fair
     value, are valued at their fair value as determined in good faith under
     consistently applied procedures under the general supervision of the
     Trustees. With respect to any portion of the Fund's assets that are
     invested in one or more open-end regulated investment companies ("RICs"),
     the Fund's net asset value ("NAV") will be calculated based upon the NAVs
     of such RICs.

     Exchange traded options and futures are valued at the settlement price
     determined by the relevant exchange. Non-exchange traded derivatives are
     normally valued on the basis of quotes obtained from brokers and dealers,
     including counterparties, or pricing services.

     Short-term instruments with less than sixty days remaining to maturity 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 then is valued at amortized cost based upon the value on
     such date unless the Trustees determine during such sixty-day period that
     amortized cost does not represent fair value.

     B. Securities transactions and income

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

     C. Distributions to shareholders

     Distributions on shares of the Fund are declared daily from net investment
     income and distributed monthly. Distributions from capital gains, if any,
     are distributed annually by the Fund. Distributions from net investment
     income and capital gains, if any, are automatically reinvested in
     additional shares of the 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
     reclassifications, are primarily due to differing treatments for capital
     loss carryovers.

     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 (loss) and accumulated net
     realized gain (loss) on investments may include temporary book and tax
     basis differences which will be distributed in a subsequent period. Any
     taxable income or gain remaining at fiscal year end is distributed in the
     following year.

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

     D. Expenses

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

     E. Commitments and contingencies

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

     F. Affiliated issuer

     Affiliated issuers are investment companies advised by Standish Mellon
     Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary
     of The Bank of New York Mellon Corporation ("BNY Mellon"), or its
     affiliates.

     G. New accounting requirements

     On September 20, 2006, the Financial Accounting Standards Board ("FASB")
     released Statement of Financial Accounting Standards No. 157 "Fair Value
     Measurements" ("FAS 157") FAS 157 establishes an authoritative definition
     of fair value, sets out a framework for measuring fair value, and requires
     additional disclosures about fair-value measurements. The application of
     FAS 157 is required for fiscal years beginning after November 15, 2007 and
     interim periods within those fiscal years. At this time, management is
     evaluating the implications of FAS 157 and its impact, if any, in the
     financial statements has not yet been determined.

(2)  Investment Advisory Fee and Other Transactions with Affiliates:

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services, and general office facilities, is
     paid monthly at the annual rate of 0.40% of the Fund's average daily net
     assets. Standish Mellon voluntarily agreed to limit the Fund's total annual
     operating expenses (excluding brokerage commissions, taxes and other
     extraordinary expenses) to 0.45% of the Fund's average daily net assets for
     the year ended September 30, 2007. Pursuant to this arrangement, for the
     year ended September 30, 2007, Standish Mellon voluntarily waived a portion
     of its investment advisory fee in the amount of $226,230. This arrangement
     is voluntary and temporary and may be discontinued or revised by Standish
     Mellon at any time.

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
     subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide
     personnel and facilities to perform transfer agency and certain shareholder
     services for the Fund. For these services the Fund pays Dreyfus Transfer,
     Inc. a fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $10,606, for the year ended September 30, 2007.

     The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"),
     a wholly-owned subsidiary of BNY Mellon and an affiliate of Standish
     Mellon, to provide custody, administration and accounting services for the
     Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset
     and transaction based fees, as well as out-of-pocket expenses. Pursuant to
     this agreement, the Fund was charged $122,378 for the year ended September
     30, 2007.

     The Trust entered into two separate agreements with The Bank of New York
     that enables the Fund, and other funds in the Trust, to borrow, in the
     aggregate, (i) up to $35 million from a committed line of credit and (ii)
     up to $15 million from an uncommitted line of credit. Interest is charged
     to each participating fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. The participating funds also
     pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
     uncommitted amounts and allocated ratably to the participating funds. In
     addition, a facility fee, computed at an annual rate of 0.060 of 1% on the
     committed amount, is allocated ratably among the participating funds at the
     end of each quarter. Pursuant to these agreements, the Fund was charged
     $1,504 for the year ended September 30, 2007, which is included in
     miscellaneous expenses on the statement of operations. See Note 6 for
     further details.

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended
     September 30, 2007, the Fund was charged $4,245, which amount is included
     in miscellaneous expenses in the statement of operations. No other
     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 Fund pays each Trustee who is not a director,
     officer or employee of Standish or its affiliates an annual fee and a per
     meeting fee as well as reimbursement for travel and out-of-pocket expenses.
     In addition, the Trust pays the legal fees for the independent counsel of
     the Trustees.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide
     printing and fulfillment services for the Fund. Pursuant to this agreement,
     the Fund was charged $4,841, which is included in miscellaneous expenses in
     the statement of operations, for the year ended September 30, 2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     year ended September 30, 2007, the Fund was charged $18,458 for fees
     payable to BNY Mellon Wealth Management.

     Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
     owned subsidiary of BNY Mellon and affiliate of Standish, replaced Mellon
     Funds Distributor, L.P. as the Fund's principal distributor.

     Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
     of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
     Mellon being the surviving entity of each merger.

     At September 30, 2007, two shareholders of record held in the aggregate 84%
     of the total outstanding shares of the Fund. Investment activities of these
     shareholders could have a material impact on the Fund.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     30 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2007, the Fund received
     $1,133 in redemption fees which is reflected in the cost of shares
     redeemed.

(5)  Federal Taxes:

     Each year, the Fund intends to qualify as a "regulated investment company"
     under Subchapter M of the Code. As such and by complying with the
     applicable provisions of the Code regarding the sources of its income, the
     timely distributions of its income to its shareholders, and the
     diversification of its assets, the Fund will not be subject to U.S. federal
     income tax on its investment company taxable income and net capital gain
     which are distributed to shareholders.

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     In July 2006, FASB issued Interpretation No. 48, "Accounting for
     Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
     (the "Interpretation"). The Interpretation establishes for all entities,
     including pass-through entities such as the Fund, a minimum threshold for
     financial statement recognition of the benefit of positions taken in filing
     tax returns (including whether an entity is taxable in a particular
     jurisdiction), and requires certain expanded tax disclosures. Adoption of
     FIN 48 is required for fiscal years beginning after December 15, 2006 and
     is to be applied to all open tax years as of the effective date. At this
     time, management is evaluating the implication of FIN 48 and its impact in
     the financial statements has not yet been determined.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2007 were as follows:

     The tax character of distributions paid during the fiscal years ended
     September 30, 2007 and September 30, 2006 was as follows:

     At September 30, 2007, 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 investment, 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

     It is uncertain whether the Fund will be able to realize the benefits of
     the losses before they expire.

(6)  Line of Credit:

     On behalf of the Fund, and other funds in the Trust, the Trust has access
     to a credit facility, which enables each fund to borrow, in the aggregate,
     up to $35 million under a committed line of credit and up to $15 million
     under an uncommitted line of credit.For the year ended September 30, 2007,
     the Fund had average borrowings outstanding of $533,000 for a total of
     twelve days and incurred $1,038 of interest expense, which is included in
     miscellaneous expenses on the statement of operations. At September 30,
     2007, the Fund did not have an outstanding loan balance.

             Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------

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

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Standish Mellon Intermediate Tax
Exempt Bond Fund (the "Fund") at September 30, 2007, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at September 30, 2007 by
correspondence with the custodian, provide a reasonable basis for our opinion.

MELLON INSTITUTIONAL FUNDS


September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

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,
Barbara McCann
President

                       Management Discussion and Analysis
- -------------------------------------------------------------------------------

For the year ended September 30, 2007, The Boston Company International Core
Equity Fund had a total return of 22.4% compared to a return of 24.9% for its
benchmark, the MSCI EAFE Index. During this period, international stocks
continued to post strong returns compared to their U.S. peers. Over the past
five years, the MSCI EAFE Index has posted an annualized return of 23.6%, the
MSCI Emerging Market Index return was up a remarkable 38.7%, while the S&P 500
return of 15.5% was well below such overseas markets. As the Fund's fiscal year
came to a close, the U.S. sub-prime difficulties, which spread globally, were
calming down as the U.S. Federal Reserve Board reduced interest rates. However,
it is clear the problem has not gone away.

Although the returns for the 12-month period ended September 30, 2007 were
strong, events around the world caused equity markets to be volatile. In the
fourth quarter of 2006, as oil and gas prices fell and interest rates were
inching down, the market returns were very positive. In the first quarter of
2007, a crackdown by the Chinese government on local investors borrowing to buy
securities in their equity market caused a few days in which global markets
tumbled. While world-wide markets were strong in April and May , returns in June
trailed as inflation concerns heightened and defaults were increasing. The MSCI
EAFE return for the quarter was 2.2%, however performance over the quarter was
volatile. The major issues centered on the U.S. sub-prime exposure, widening
bond spreads and a lack of liquidity in the credit markets. The credit
tightening triggered quantitative models to perform in a perverse fashion as
stocks that were unattractive on many valuation measures were being purchased by
some large hedge funds to cover their short positions, thus pushing up prices of
these unattractive stocks. Faced with the prospect of economic fallout and under
intense political and market pressure, central bankers were compelled to expand
liquidity. The Federal Reserve Board cut rates by fifty basis points and the
market rallied.

The strong returns over the period were broad-based with all countries and
sectors reporting positive returns. Finland was the best performing country with
a 68% return while Japan was the laggard with a 7% return. The Materials sector
was the best performing sector with a 56% return, as the growth in the emerging
markets continues to fuel demand for materials as infrastructure expands.
Healthcare was the weakest sector reporting a 4.6% return. Failures in tests,
patent expirations and impeding lawsuits hurt the returns of global health care
stocks.

Stock selection for the Fund was mixed for the twelve-month period ended
September 30, 2007. Stock selection in Japan, Finland and Belgium was very
strong with each attributing more than fifty basis points in excess of the
relative return. Stock selection in the UK was weak, as the economy was hit
particularly hard with the concerns related to the sub-prime credit crisis. The
Fund's stock selection in the U.K. underperformed by 5.5% the benchmark return
of 22.4% and was responsible for negative eighty basis points to the relative
return.

                       Management Discussion and Analysis
- -------------------------------------------------------------------------------

From the sector perspective, financials had the largest negative effect on the
portfolio, again reflecting sub-prime contagion. The financial portfolio
holdings were well diversified with attractive valuations, however companies
exposed to mortgage underwriting reported that there would be writeoffs and
earnings would be negatively affected. Financials underperformed the benchmark
index by 6%. The Industrial sector was the best performer with a 54.7% return as
compared to the benchmark's return of 38.3%. A significant story during the
third quarter of 2007 was the "quant blowup" caused by major hedge funds
liquidating positions in mid-August. From August 8 through August 10, stocks
that were rated highly in our models underperformed and those that ranked poorly
outperformed. During this time,factors such as valuation and momentum which have
been strong indicators of positive alpha had negative attribution to the
relative return. This had a negative effect on the portfolio.

Looking toward the future, while we believe that the sub-prime crisis has
subsided, it is clear it has not gone away completely. Commodity prices remain
firm with oil trading at an all time high of over $80a barrel. The threat of
inflation is lurking, as U.S. GDP numbers are being lowered. That said, the
reliance on the US for global growth is not as important as it has been in the
past. The emerging markets and in particular the "BRIC"s (Brazil, Russia, India
and China) continue to demand goods and services to address infrastructure
needs. Europe is benefiting from intra regional exports and 40% of Japanese
companies are trading below book value. Taken together, we believe that these
facts support positive future returns. As always, we remain disciplined in our
investment philosophy as we believe the best opportunity is through stock
selection. The Fund will continue to seek to invest in stocks which combine
better than peer-group business momentum and better than peer-group valuation
characteristics. This is the time tested philosophy the Fund has followed since
inception, and we believe this methodology will continue to produce attractive
long-term results for shareholders.

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

               The Boston Company International Core Equity Fund

                    Shareholder Expense Example (Unaudited)
- -------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

                   Mellon Institutional Funds Investment Trust
               The Boston Company International Core Equity Fund

                         Notes to Financial Statements
- -------------------------------------------------------------------------------

(1)  Organization and Significant Accounting Policies:

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

     The 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 companies
     that are represented in the MSCI Europe, Australia, Far East (EAFE) Index
     and Canada. The Fund may invest up to 25% of assets in emerging market
     countries. The Fund may also invest in equity index futures contracts based
     primarily on the indices of countries included in the EAFE Index and
     Canada.

     Prior to September 20, 2007, the Fund had invested substantially all of its
     investable assets in The Boston Company International Core Equity Portfolio
     (the "Portfolio"), a subtrust of the Mellon Institutional Funds Master
     Portfolio, the "Portfolio Trust", a New York trust. The Portfolio had
     investment objectives, policies, limitations and accounting policies
     substantially identical to those of the Fund. While investing in the
     Portfolio, the Fund earned its proportionate share of the Portfolio's
     income, expenses, and realized and unrealized gains and losses based on its
     percentage ownership of the Portfolio's shares of beneficial interest. The
     Portfolio's Statement of Operations for the period October 1, 2006 through
     September 19, 2007 is included in Note 9. On September 19, 2007, the Fund,
     which owned 100% of the Portfolio on that date, withdrew entirely from the
     Portfolio and received the Portfolio's assets, including securities and
     cash, and assumed the Portfolio's stated liabilities in exchange for its
     interest in the Portfolio. Effective September 20, 2007, the Fund began
     investing directly in the securities in which the Portfolio had invested.

     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

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. Securities are valued at the last sale prices on the exchange or
     national securities market on which they are primarily traded. Securities
     not listed on an exchange or national securities market, or securities for
     which there were no reported transactions, are valued at the last
     calculated mean price (average of last bid and last offer). Securities that
     are fixed income securities, other than short-term instruments with less
     than sixty days remaining to maturity, for which accurate market prices are
     readily available, are valued at their current market value on the basis of
     quotations, which may be furnished by a pricing service or dealers in such
     securities. Securities (including illiquid securities) for which quotations
     are not readily available, or if such quotations do not accurately reflect
     fair value, are valued at their fair value as determined in good faith
     under consistently applied procedures under the general supervision of the
     Trustees. With respect to any portion of the Fund's assets that are
     invested in one or more open-end regulated investment companies ("RICs"),
     the Fund's net asset value ("NAV") is calculated based upon the NAVs of
     such RICs.

     Exchange traded options and futures are valued at the settlement price
     determined by the relevant exchange. Non-exchange traded derivatives are
     normally valued on the basis of quotes obtained from brokers and dealers,
     including counterparties or pricing services.

     Because foreign markets may be open at different times than the NYSE, the
     value of the Fund's shares may change on days when shareholders are not
     able to buy or sell them. Many securities markets and exchanges outside the
     U.S. close prior to the close of the NYSE and therefore the closing prices
     for securities in such markets or on such exchanges may not fully reflect
     the events that occur after such close but before the close of the NYSE.

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

     Short-term instruments with less than sixty days remaining to maturity 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 cost based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized cost does not represent fair value.

                          Notes to Financial Statements
- -------------------------------------------------------------------------------

     B. Securities transactions and income

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of coupon interest accrued, adjusted for accretion
     of discount or amortization of premium using the yield-to-maturity method
     on debt securities with greater than sixty days remaining to maturity.
     Dividend income is recorded on the ex-dividend date. Dividends representing
     a return of capital are reflected as a reduction of cost. Realized gains
     and losses from securities sold are recorded on the identified cost basis.
     Income, expenses and realized and unrealized gains and losses allocated
     from the Portfolio represent the Fund's proportionate share of those items
     earned by the Portfolio during the period October 1, 2006 through September
     19, 2007.

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

     C. Distributions to shareholders

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from 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 reclassifications, are primarily due to differing
     treatments for foreign currency transactions and losses deferred due to
     wash sales.

     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 (loss) and accumulated net
     realized gain (loss) on investments may include temporary book and tax
     basis differences which will be distributed in a subsequent period. Any
     taxable income or gain remaining at fiscal year end is distributed in the
     following year.

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

     On July 31, 2007, the Dreyfus Premier International Equity Fund ("Dreyfus
     Feeder") withdrew from the master feeder structure via a redemption-in-kind
     and received currency and securities with unrealized appreciation of
     $57,244,763 for the value of their interest in the Portfolio. The Fund
     realized no gain on this transaction. $40,597,582 of unrealized
     appreciation had been allocated to that feeder fund. The Fund increased
     paid in capital and decreased unrealized appreciation on investments by
     $16,647,181 to recognize this difference. This reclassification had no
     impact on the net assets or results of operations of the Fund.

     D. Expenses

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

     E. Foreign currency transactions

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

     F. Foreign investment risk

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

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


     G. Commitments and contingencies

     In the normal course of business, the 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.

     H. Affiliated issuers

     Affiliated issuers are investment companies advised by The Boston Company
     Asset Management LLC. ("TBCAM"), a wholly-owned subsidiary of The Bank of
     New York Mellon Corporation ("BNY Mellon"), or its affiliates.

     I. New accounting requirements

     On September 20, 2006, the Financial Accounting Standards Board ("FASB")
     released Statement of Financial Accounting Standards No. 157 "Fair Value
     Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition
     of fair value, sets out a framework for measuring fair value, and requires
     additional disclosures about fair-value measurements. The application of
     FAS 157 is required for fiscal years beginning after November 15, 2007 and
     interim periods within those fiscal years. At this time, management is
     evaluating the implications of FAS 157 and its impact, if any, in the
     financial statements has not yet been determined.

(2)  Investment Advisory Fee and Other Transactions With Affiliates:

     Prior to September 20, 2007 the Fund did not directly incur any investment
     advisory, custody, administration and commitment fees, which were incurred
     by the Portfolio and allocated to the Fund based on its proportionate
     interest in the Portfolio. The following disclosures relating to these fees
     represent fees incurred by the Portfolio for the period prior to September
     20, 2007, and by the Fund thereafter.

     The investment advisory fee paid to TBCAM for overall investment advisory,
     and administrative services, and general office facilities, is paid monthly
     at the annual rate of 0.80% of the first $500 million of the Fund's, and
     previously the Portfolio's, average daily net assets, 0.75% of the next
     $500 million, and 0.70% of the next $500 million, 0.60% of the next $500
     million, and 0.50% on assets over $2 billion.

     For the period of September 1, 2007 through August 31, 2008, TBCAM has
     agreed to rebate 0.25% of its management fee to the Fund. This rebate will
     end on September 1, 2008, and on such date the Fund's contractual advisory
     fee will again be in effect. This rebate will not change any existing
     voluntary total expense limitation arrangements that are in effect, as
     TBCAM will continue its commitment to maintain such total expense
     limitations during this rebate period. For the period October 1, 2006
     through September 19, 2007, TBCAM rebated $125,843 of its investment
     advisory fees charged to the Portfolio. For the period September 20, 2007
     through September 30, 2007, TBCAM rebated $92,386 of its investment
     advisory fees charged to the Fund.

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide personnel
     and facilities to perform transfer agency and certain shareholder services
     for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a
     fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $107,940, for the year ended September 30, 2007.

     The Trust, and previously the Portfolio Trust, entered into an agreement
     with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of BNY
     Mellon and an affiliate of TBCAM, to provide custody, administration and
     accounting services for the Portfolio/Fund. For these services the Fund
     pays Mellon Bank a fixed fee plus asset and transaction based fees, as well
     as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $1,401,006 for the period October 1, 2006 to September 19, 2007 and $43,397
     for the period September 20, 2007 to September 30, 2007.

     The Trust, and previously the Portfolio Trust, also entered into an
     agreement with Mellon Bank to perform certain securities lending activities
     and to act as the Portfolio/Fund's lending agent. Mellon Bank receives an
     agreed upon percentage of the net lending revenues. Pursuant to this
     agreement, the Fund was charged $47 for the period October 1, 2006 to
     September 19, 2007 and $0 for the period September 20, 2007 to September
     30, 2007. See Note 7 for further details.

                         Notes to Financial Statements
- -------------------------------------------------------------------------------

     The Trust, and previously the Portfolio Trust, entered into two separate
     agreements with The Bank of New York that enables the Fund, and other funds
     in the Trust, to borrow, in the aggregate, (i) up to $35 million from a
     committed line of credit and (ii) up to $15 million from an uncommitted
     line of credit. Interest is charged to each participating fund based on its
     borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
     1%. The participating funds also pay an annual fee, computed at a rate of
     0.020 of 1% of the committed and uncommitted amounts and allocated ratably
     to the participating funds. In addition, a facility fee, computed at an
     annual rate of 0.060 of 1% on the committed amount, is allocated ratably
     among the participating funds at the end of each quarter. Pursuant to these
     agreements, the Fund was charged $14,389 for the period October 1, 2006 to
     September 19, 2007 and the fund was charged $370 for the period September
     20, 2007 to September 30, 2007, which is included in miscellaneous expenses
     on the statement of operations. See Note 8 for further details.

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended
     September 30, 2007, the Fund was charged $4,241, which amount is included
     in miscellaneous expenses in the statement of operations. No other
     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 Fund pays each Trustee who is not a director,
     officer or employee of TBCAM or its affiliates an annual fee and a per
     meeting fee as well as reimbursement for travel and out-of-pocket expenses.
     In addition, the Trust pays the legal fees for the independent counsel of
     the Trustees.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide printing and
     fulfillment services for the Fund. Pursuant to this agreement, the Fund was
     charged $37,930, which amount is included in miscellaneous expenses in the
     statement of operations, for the year ended September 30, 2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     year ended September 30, 2007, the Fund was charged $156,191 payable to BNY
     Mellon Wealth Management.

     Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
     owned subsidiary of BNY Mellon and affiliate of TBCAM, replaced Mellon
     Funds Distributor, L.P. as the Fund's principal distributor.

     Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
     of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
     Mellon being the surviving entity of each merger.

At September 30, 2007, one shareholder of record held approximately 23.5% of the
total outstanding shares of the Fund. Investment activities of this shareholder
could have a material impact on the Fund.

               The Boston Company International Core Equity Fund

                         Notes to Financial Statements
- -------------------------------------------------------------------------------

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     30 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2007, the Fund received
     $75,412 in redemption fees and is reflected in the cost of shares redeemed.


(5)  Federal Taxes:

     Each year, the Fund intends to qualify as a "regulated investment company"
     under Subchapter M of the Code. As such and by complying with the
     applicable provisions of the Code regarding the sources of its income, the
     timely distributions of its income to its shareholders, and the
     diversification of its assets, the Fund will not be subject to U.S. federal
     income tax on its investment company taxable income and net capital gain
     which are distributed to shareholders.

     In July 2006, FASB issued Interpretation No. 48, "Accounting for
     Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
     (the "Interpretation"). The Interpretation establishes for all entities,
     including pass-through entities such as the Fund, a minimum threshold for
     financial statement recognition of the benefit of positions taken in filing
     tax returns (including whether an entity is taxable in a particular
     jurisdiction), and requires certain expanded tax disclosures. Adoption of
     FIN 48 is required for fiscal years beginning after December 15, 2006 and
     is to be applied to all open tax years as of the effective date. At this
     time, management is evaluating the implication of FIN 48 and its impact in
     the financial statements has not yet been determined.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2007 were as follows:

(6)  Financial Instruments:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved.

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

     Futures contracts

     The Fund, and previously the portfolio, may enter into financial futures
     contracts for the purchase or sale of securities, or contracts based on
     financial indices at a fixed price on a future date. Pursuant to 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 appreciation or depreciation 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


                                       21


                   Mellon Institutional Funds Investment Trust
               The Boston Company International Core Equity Fund

                         Notes to Financial Statements
- -------------------------------------------------------------------------------

     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 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 also arise if there is an illiquid secondary
     market or if the counterparty does not perform under the contract's terms.
     The Fund enters into financial futures transactions primarily to seek to
     manage its exposure to certain markets and to changes in securities prices
     and foreign currencies. Gains and losses are realized upon the expiration
     or closing of the futures contracts. Futures contracts are valued at the
     quoted daily settlement prices established by the exchange on which they
     trade.

     At September 30, 2007, the Fund held open financial futures contracts. See
     the Schedule of Investments for further details.

     Forward Foreign Currency Exchange Contracts

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

     At September 30, 2007, the Fund held forward foreign currency exchange
     contracts. See Schedule of Investments for further details.

(7)  Security Lending:

     The Fund, and previously the Portfolio, 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, and previously the Portfolio, loaned securities during the year
     ended September 30, 2007 and earned interest on the invested collateral of
     $392 of which $346 was rebated to borrowers or paid in fees. At September
     30, 2007, the Fund did not have securities out on loan.

(8)  Line of Credit:

     On behalf of the Fund, and other funds in the Trust, and previously the
     portfolios in the Portfolio Trust, the Trust has access to a credit
     facility, which enables each fund to borrow, in the aggregate, up to $35
     million under a committed line of credit and up to $15 million under an
     uncommitted line of credit.

     For the year ended September 30, 2007, the Fund and the Portfolio had
     average borrowings outstanding of $14,676,875 for a total of eight days and
     incurred $4,997 for the period October 1, 2006 to September 19, 2007 and
     $13,135 for the period September 20, 2007 to September 30, 2007, of
     interest expense. At September 30, 2007, the Fund did not have a loan
     balance outstanding.

(9)  Reorganization:

     Prior to September 19, 2007, the Fund had utilized a Master Feeder Fund
     structure where the Fund sought to achieve its investment objectives by
     investing all of its investable assets in the Boston Company International
     Core Equity Portfolio. Effective after the close of business on September
     19, 2007, the Fund withdrew its assets from the Portfolio by means of a
     redemption-in-kind and now the Fund invests directly in portfolio
     securities.

     Below is the Statement of Operations for The Boston Company International
     Core Equity Portfolio for the period from October 1, 2006 to September 19,
     2007:

               The Boston Company International Core Equity Fund

            Report of Independent Registered Public Accounting Firm
- -------------------------------------------------------------------------------

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

     In our opinion, the accompanying statement of assets and liabilities,
     including the schedule of investments, and the related statements of
     operations and of changes in net assets and the financial highlights
     present fairly, in all material respects, the financial position of The
     Boston Company International Core Equity Fund (the "Fund") at September 30,
     2007, the results of its operations for the year then ended, the changes in
     its net assets for each of the two years in the period then ended and the
     financial highlights for each of the five years in the period then ended,
     in conformity with accounting principles generally accepted in the United
     States of America. These financial statements and financial highlights
     (hereafter referred to as "financial statements") are the responsibility of
     the Fund's management. Our responsibility is to express an opinion on these
     financial statements based on our audits. We conducted our audits of these
     financial statements in accordance with the standards of the Public Company
     Accounting Oversight Board (United States). Those standards require that we
     plan and perform the audit to obtain reasonable assurance about whether the
     financial statements are free of material misstatement. An audit includes
     examining, on a test basis, evidence supporting the amounts and disclosures
     in the financial statements, assessing the accounting principles used and
     significant estimates made by management, and evaluating the overall
     financial statement presentation. We believe that our audits, which
     included confirmation of securities at September 30, 2007 by correspondence
     with the custodian and brokers, provide a reasonable basis for our opinion.

MELLON INSTITUTIONAL FUNDS

September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

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,
Barbara McCann
President

                   Mellon Institutional Funds Investment Trust
                The Boston Company International Small Cap Fund

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

For the year ended September 30, 2007, The Boston Company International Small
Cap Fund had a total return of 24.5% compared to a return of 26.8% for its
benchmark, the S&P Citigroup World EMI ex-US Index. During this period,
international stocks continued to post strong returns compared to their U.S.
peers. Over the past five years, the S&P Citigroup World EMI ex-US Index has
posted an annualized return of 29.6%, while the MSCI EAFE Index and the MSCI
Emerging Market Index were up 23.6% and 38.7%, respectively. Meanwhile, the S&P
500 returned 15.5%, which was well below the overseas markets. As the Fund's
fiscal year came to a close, the U.S. sub-prime difficulties which spread
globally were calming down as the U.S. Federal Reserve Board reduced interest
rates. However, it is clear the problem has not gone away.

Although the returns for the 12-month period ended September 30, 2007 were
strong, events around the world caused equity markets to be volatile. In the
fourth quarter of 2006, as oil and gas prices fell and interest rates were
inching down, the market returns were very positive. In the first quarter of
2007, a crackdown by the Chinese government on local investors borrowing to buy
securities in their equity market caused a few days in which global markets
tumbled. While worldwide markets were strong in April and May, returns in June
trailed as inflation concerns heightened and defaults were increasing. The S&P
Citigroup World EMI ex-US Index returned -0.4% this past quarter, yet
performance over the quarter was volatile. The major issues centered on the U.S.
sub-prime exposure, widening bond spreads and a lack of liquidity in the credit
markets. The credit tightening triggered quantitative models to perform in a
perverse fashion as stocks that were unattractive on many valuation measures
were being purchased by some large hedge funds to cover their short positions,
thus pushing up prices of these unattractive stocks. Faced with the prospect of
economic fallout and under intense political and market pressure, central
bankers were compelled to expand liquidity. The Federal Reserve Board cut rates
by fifty basis points and the market rallied.

The strong returns over the period were broad-based with all countries except
one and all sectors reporting positive returns. South Korea and Slovenia were
the best performing countries with returns of 78.7% and 173%, respectively.
Japan, the only country with a negative return, was the weakest market in the
benchmark with a -1.9% return. The Materials sector was the best performing
sector with a 47% return, as growth in the emerging markets continues to fuel
demand for materials as infrastructure expands. Information Technology was the
weakest sector in the benchmark reporting a 16% return.

Stock selection for the Fund was mixed for the twelve month period ended
September 30, 2007. Stock selection in both Switzerland and Finland was very
strong. The Fund's stock selection in Switzerland, with a 51% return,
outperformed the benchmark return of 32% by 19%. The Fund's stock selection in
Finland, with an 83% return, outperformed the benchmark return of 51% by 32%.
Stock selection in the UK was weak, as the country was hit particularly hard
with concerns related to the sub-prime credit crisis. The Fund's stock selection
in the UK underperformed by 4.7% the benchmark return of 18.8% and was
responsible for negative eighty basis points to the relative return. Japan stock
selection was also weak contributing a negative forty-seven basis points to the
return.

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

From the sector perspective, financials had the largest negative effect on the
portfolio, again reflecting sub-prime contagion. The financial portfolio
holdings were well diversified with attractive valuations, however companies
exposed to mortgage underwriting reported that there would be writeoffs and
earnings would be negatively affected. Financials underperformed the benchmark
index by 5%. The Materials sector was the best performer with a 53.8% return as
compared to the benchmark's return of 46.9%. A significant story during the
third quarter of 2007 was the "quant blowup" caused by major hedge funds
liquidating positions in mid-August. From August 8 through August 10, stocks
that were rated highly in our models underperformed and those that ranked poorly
outperformed. During this time, factors such as valuation and momentum which
have been strong indicators of positive alpha had negative attribution to the
relative return. This had a negative effect on the portfolio.

Looking toward the future, while we believe that the sub-prime crisis has
subsided, it is clear it has not gone away completely. Commodity prices remain
firm with oil trading at an all time high of over $80 a barrel. The threat of
inflation is lurking, as U.S. GDP numbers are being lowered. That said, the
reliance on the US for global growth is not as important as it has been in the
past. The emerging markets and in particular the "BRIC"s (Brazil, Russia, India
and China) continue to demand goods and services to address infrastructure
needs. Europe is benefiting from intraregional exports and 40% of Japanese
companies are trading below book value. Taken together, we believe that these
facts support positive future returns. As always, we remain disciplined in our
investment philosophy as we believe the best opportunity is through stock
selection. The Fund will continue to seek to invest in stocks which combine
better than peer-group business momentum and better than peer-group valuation
characteristics. This is the time tested philosophy the Fund has followed since
inception, and we believe this methodology will continue to produce attractive
long-term results for shareholders.

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

                    Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

*    The investment advisor voluntarily agreed not to impose a portion of its investment advisory fee and/or reimburse the
     Fund for all or a portion of its operating expenses. If this voluntary action had not been taken, the investment income

(c)  For the period October 1, 2006 to September 19, 2007 and for the fiscal
     years ended September 30, 2003-2006, the ratio includes the Fund's share of
     the TBC International Small Cap Portfolio's allocated expenses.
(d)  On September 19, 2007, the Fund, which had owned approximately 100% of the
     Portfolio on such date, withdrew entirely from the Portfolio and received
     the Portfolio's securities and cash in exchange for its interests in the
     Portfolio. Effective September 20, 2007, the Fund began investing directly
     in the securities in which the Portfolio had invested. Portfolio turnover
     represents investment activity of both the Fund and the Portfolio for the
     year. The amounts shown for 2004-2006 are the ratios for the Portfolio.
(e)  Portfolio turnover represents activity while the Fund was investing
     directly in securities until January 23, 2003. The Portfolio turnover for
     the period January 24, 2003 to September 30, 2003 was 46%.

                         Notes to Financial Statements

(1)  Organization and Significant Accounting Policies:

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

     The 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 companies
     that are located in foreign countries represented in the S&P Citigroup
     World Extended Market Ex.-U.S. (EMI Ex-U.S.) Index. The EMI Ex-U.S. Index
     is made up of those companies representing the lowest 20% of each country's
     total available market capitalization. The Fund may invest up to 25% of
     assets in emerging market countries.

     Prior to September 20, 2007, the Fund had invested substantially all of its
     investable assets in The Boston Company International Small Cap Portfolio
     (the "Portfolio"), a subtrust of the Mellon Institutional Funds Master
     Portfolio, the "Portfolio Trust", a New York trust. The Portfolio had
     investment objectives, policies, limitations and accounting policies
     substantially identical to those of the Fund. While investing in the
     Portfolio, the Fund earned its proportionate share of the Portfolio's
     income, expenses, and realized and unrealized gains and losses based on its
     percentage ownership of the Portfolio's shares of beneficial interest. The
     Portfolio's Statement of Operations for the period October 1, 2006 through
     September 19, 2007 is included in Note 9. On September 19, 2007, the Fund,
     which owned 100% of the Portfolio on that date, withdrew entirely from the
     Portfolio and received the Portfolio's assets, including securities and
     cash, and assumed the Portfolio's stated liabilities in exchange for its
     interest in the Portfolio. Effective September 20, 2007, the Fund began
     investing directly in the securities in which the Portfolio had invested.

     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

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. Securities are valued at the last sale prices on the exchange or
     national securities market on which they are primarily traded. Securities
     not listed on an exchange or national securities market, or securities for
     which there were no reported transactions, are valued at the last
     calculated mean price (average of last bid and last offer). Securities that
     are fixed income securities, other than short-term instruments with less
     than sixty days remaining to maturity, for which accurate market prices are
     readily available, are valued at their current market value on the basis of
     quotations, which may be furnished by a pricing service or dealers in such
     securities. Securities (including illiquid securities) for which quotations
     are not readily available, or if such quotations do not accurately reflect
     fair value, are valued at their fair value as determined in good faith
     under consistently applied procedures under the general supervision of the
     Trustees. With respect to any portion of the Fund's assets that are
     invested in one or more open-end regulated investment companies ("RICs"),
     the Fund's net asset value ("NAV") is calculated based upon the NAVs of
     such RICs.

     Exchange traded options and futures are valued at the settlement price
     determined by the relevant exchange. Non-exchange traded derivatives are
     normally valued on the basis of quotes obtained from brokers and dealers,
     including counterparties or pricing services.

     Because foreign markets may be open at different times than the NYSE, the
     value of the Fund's shares may change on days when shareholders are not
     able to buy or sell them. Many securities markets and exchanges outside the
     U.S. close prior to the close of the NYSE and therefore the closing prices
     for securities in such markets or on such exchanges may not fully reflect
     the events that occur after such close but before the close of the NYSE.

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

     Short-term instruments with less than sixty days remaining to maturity 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 cost based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized cost does not represent fair value.

                         Notes to Financial Statements
- --------------------------------------------------------------------------------

     B. Securities transactions and income

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of coupon interest accrued, adjusted for accretion
     of discount or amortization of premium using the yield-to-maturity method
     on debt securities with greater than sixty days remaining to maturity.
     Dividend income is recorded on the ex-dividend date. Dividends representing
     a return of capital are reflected as a reduction of cost. Realized gains
     and losses from securities sold are recorded on the identified cost basis.
     Income, expenses and realized and unrealized gains and losses allocated
     from the Portfolio represent the Fund's proportionate share of those items
     earned by the Portfolio during the period October 1, 2006 through September
     19, 2007.

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

     C. Distributions to shareholders

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from 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 reclassifications, are primarily due to differing
     treatments for foreign currency transactions, losses deferred due to wash
     sales, passive foreign investment companies (PFIC) and equalization.

     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 (loss) and accumulated net
     realized gain (loss) on investments may include temporary book and tax
     basis differences which will be distributed in a subsequent period. Any
     taxable income or gain remaining at fiscal year end is distributed in the
     following year.

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

     On July 31, 2007, the Dreyfus Premier International Small Cap Fund
     ("Dreyfus Feeder") withdrew from the master feeder structure via a
     redemption-in-kind and received currency and securities with unrealized
     appreciation of $79,724,556 for the value of their interest in the
     Portfolio. The Fund realized no gain on this transaction. $59,333,708 of
     unrealized appreciation had been allocated to that feeder fund. The Fund
     increased paid in capital and decreased unrealized appreciation on
     investments by $20,390,848 to recognize this difference. This
     reclassification had no impact on the net assets or results of operations
     of the Fund.

     D. Expenses

     The majority of expenses of the Trust are directly identifiable to an
     individual fund. Expenses which are not readily identifiable to a specific
     fund are allocated among the funds of the Trust taking into consideration,
     among other things, the nature and type of expense and the relative size of
     the funds. E. Foreign currency transactions The Fund maintains its books
     and records in U.S. dollars. Investment security valuations and other
     assets and liabilities initially expressed in foreign currencies are
     converted into U.S. dollars based upon current currency exchange rates.
     Purchases and sales of foreign investment securities and income and
     expenses are converted into U.S. dollars based upon currency exchange rates
     prevailing on the respective dates of such transactions.

     F. Foreign investment risk

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

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

     G. Commitments and contingencies

     In the normal course of business, the 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.

     H. Affiliated issuers

     Affiliated issuers are investment companies advised by The Boston Company
     Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of The Bank of
     New York Mellon Corporation ("BNY Mellon"), or its affiliates.

     I. New accounting requirements

     On September 20, 2006, the Financial Accounting Standards Board ("FASB")
     released Statement of Financial Accounting Standards No. 157 "Fair Value
     Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition
     of fair value, sets out a framework for measuring fair value, and requires
     additional disclosures about fair-value measurements. The application of
     FAS 157 is required for fiscal years beginning after November 15, 2007 and
     interim periods within those fiscal years. At this time, management is
     evaluating the implications of FAS 157 and its impact, if any, in the
     financial statements has not yet been determined.

(2)  Investment Advisory Fee and Other Transactions With Affiliates:

     Prior to September 20, 2007 the Fund did not directly incur any investment
     advisory, custody, administration and commitment fees, which were incurred
     by the Portfolio and allocated to the Fund based on its proportionate
     interest in the Portfolio. The following disclosures relating to these fees
     represent fees incurred by the Portfolio for the period prior to September
     20, 2007, and by the Fund thereafter.

     The investment advisory fee paid to TBCAM for overall investment advisory
     and administrative services, and general office facilities, is paid monthly
     at the annual rate of 1.00% of the Fund's average daily net assets.

     For the period of September 1, 2007 through August 31, 2008, TBCAM has
     agreed to rebate 0.25% of its management fee to the Fund. This rebate will
     end on September 1, 2008, and on such date the Fund's contractual advisory
     fee will again be in effect. This rebate will not change any existing
     voluntary total expense limitation arrangements that are in effect, as
     TBCAM will continue its commitment to maintain such total expense
     limitations during this rebate period. For the period October 1, 2006
     through September 19, 2007, TBCAM rebated $103,350 of its investment
     advisory fees charged to the Portfolio. For the period September 20, 2007
     through September 30, 2007, TBCAM rebated $29,167 of its investment
     advisory fees charged to the Fund.

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide personnel
     and facilities to perform transfer agency and certain shareholder services
     for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a
     fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $45,781, for the year ended September 30, 2007.

     The Trust, and previously the Portfolio Trust, entered into an agreement
     with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of BNY
     Mellon and an affiliate of TBCAM, to provide custody, administration and
     accounting services for the Portfolio/Fund. For these services the Fund
     pays Mellon Bank a fixed fee plus asset and transaction based fees, as well
     as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $697,943 for the period October 1, 2006 to September 19, 2007 and $21,653
     for the period September 20, 2007 to September 30, 2007.

     The Trust, and previously the Portfolio Trust, also entered into an
     agreement with Mellon Bank to perform certain securities lending activities
     and to act as the Portfolio/Fund's lending agent. Mellon Bank receives an
     agreed upon percentage of the net lending revenues. Pursuant to this
     agreement, Mellon Bank earned 110,671 for the period October 1, 2006 to
     September 19, 2007 and $0 for the period September 20, 2007 to September
     30, 2007. See Note 7 for further details.

     The Trust, and previously the Portfolio Trust, entered into two separate
     agreements with The Bank of New York that enable the Fund, and other funds
     in the Trust, to borrow, in the aggregate, (i) up to $35 million from a
     committed line of credit and (ii) up to $15 million from an uncommitted
     line of credit. Interest is charged to each participating fund based on its
     borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
     1%. The

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

     participating funds also pay an annual fee, computed at a rate of 0.020 of
     1% of the committed and uncommitted amounts and allocated ratably to the
     participating funds. In addition, a facility fee, computed at an annual
     rate of 0.060 of 1% on the committed amount, is allocated ratably among the
     participating funds at the end of each quarter. Pursuant to these
     agreements, the Fund was charged $8,904 for the period October 1, 2006 to
     September 19, 2007 and $287 for the period September 20, 2007 to September
     30, 2007, which is included in miscellaneous expenses on the statement of
     operations. See Note 8 for further details.

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended
     September 30, 2007, the Fund was charged $4,255, which amount is included
     in miscellaneous expenses in the statement of operations. No other
     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 Fund pays each Trustee who is not a director,
     officer or employee of TBCAM or its affiliates an annual fee and a per
     meeting fee as well as reimbursement for travel and out-of-pocket expenses.
     In addition, the Trust pays the legal fees for the independent counsel of
     the Trustees.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide printing and
     fulfillment services for the Fund. Pursuant to this agreement, the Fund was
     charged $12,684, which amount is included in miscellaneous expenses in the
     statement of operations, for the year ended September 30, 2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     year ended September 30, 2007, the Fund was charged $107,882 for fees
     payable to BNY Mellon Wealth Management.

     Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
     owned subsidiary of BNY Mellon and affiliate of TBCAM, replaced Mellon
     Funds Distributor, L.P. as the Fund's principal distributor.

     Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
     of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
     Mellon being the surviving entity of each merger.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended September 30, 2007 were as follows:



                                                                     Purchases          Sales

(4)  Shares of Beneficial Interest:

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



                                                       For the                      For the

Net increase (decrease)                               ===========                   =========


     At September 30, 2007, four shareholders of record, in the aggregate, held
     approximately 47.7% of the total outstanding shares of the Fund. Investment
     activities of these shareholders could have a material impact on the Fund.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     30 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2007, the Fund received
     $7,754 in redemption fees and is reflected in the cost of shares redeemed.

(5)  Federal Taxes:

     Each year, the Fund intends to qualify as a "regulated investment company"
     under Subchapter M of the Code. As such and by complying with the
     applicable provisions of the Code regarding the sources of its income, the
     timely distributions of its income to its shareholders, and the
     diversification of its assets, the Fund will not be subject to U.S. federal
     income tax on its investment company taxable income and net capital gain
     which are distributed to shareholders.

     In July 2006, FASB issued Interpretation No. 48, "Accounting for
     Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
     (the "Interpretation"). The Interpretation establishes for all entities,
     including pass-through entities such as the Fund, a minimum threshold for
     financial statement recognition of the benefit of positions taken in filing
     tax returns (including whether an entity is taxable in a particular
     jurisdiction), and requires certain expanded tax disclosures. Adoption of
     FIN 48 is required for fiscal years beginning after December 15, 2006 and
     is to be applied to all open tax years as of the effective date. At this
     time, management is evaluating the implication of FIN 48 and its impact on
     the financial statements has not yet been determined.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2007 were as follows:


                                                                                              
                      Cost for federal income tax purposes                     $442,963,380

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

     Futures contracts

     The Fund, and previously the Portfolio, may enter into financial futures
     contracts for the purchase or sale of securities, or contracts based on
     financial indices at a fixed price on a future date. Pursuant to 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 appreciation or depreciation 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 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
     also arise if there is an illiquid secondary market or if the counterparty
     does not perform under the contract's terms. The Fund enters into financial
     futures transactions primarily to seek to manage its exposure to certain
     markets and to changes in securities prices and foreign currencies. Gains
     and losses are realized upon the expiration or closing of the futures
     contracts. Futures contracts are valued at the quoted daily settlement
     prices established by the exchange on which they trade.

     At September 30, 2007, the Fund held open financial futures contracts. See
     the Schedule of Investments for further details.

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

     Forward Foreign Currency Exchange Contracts

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

     At September 30, 2007, the Fund held forward foreign currency exchange
     contracts. See Schedule of Investments for further details.

(7)  Security Lending:

     The Fund, and previously the Portfolio, 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, and previously the Portfolio, loaned securities during the year
     ended September 30, 2007 and earned interest on the invested collateral of
     $129,601 of which $18,930 was rebated to borrowers or paid in fees. At
     September 30, 2007, the Fund did not have any securities out on loan.

(8)  Line of Credit:

     On behalf of the Fund and other funds in the Trust, and previously the
     Portfolios in the Portfolio Trust, the Trust has access to a credit
     facility, which enables each fund to borrow, in the aggregate, up to $35
     million under a committed line of credit and up to $15 million under an
     uncommitted line of credit. For the year ended September 30, 2007, the Fund
     had average borrowings outstanding of $10,974,467 for a total of fifteen
     days and incurred interest expense of $26,806 for the period October 1,
     2006 to September 19, 2007 and $10 for the period September 20, 2007 to
     September 30, 2007. At September 30, 2007, the Fund did not have a loan
     balance outstanding.

(9)  Reorganization:

     Prior to September 19, 2007, the Fund had utilized a Master Feeder Fund
     structure where the Fund sought to achieve its investment objectives by
     investing all of its investable assets in the Boston Company International
     Small Cap Portfolio. Effective after the close of business on September 19,
     2007, the Fund withdrew its assets from the Portfolio by means of a
     redemption-in-kind and now the Fund invests directly in portfolio
     securities.

     Below is the Statement of Operations for The Boston Company International
     Small Cap Portfolio for the period October 1, 2006 to September 19, 2007:

             Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------

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

In our opinion, the accompanying statement of assets and liabilities, including
schedule of investments, and the related statements of operations and of changes
in net assets and the financial highlights present fairly, in all material
respects, the financial position of The Boston Company International Small Cap
Fund (the "Fund") at September 30, 2007, the results of its operations for the
year then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with accounting principles generally accepted
in the United States of America. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2007 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

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,
Barbara McCann
President

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

Stock prices were buoyed throughout the reporting period by positive U.S. and
global economic growth and strong corporate earnings. However, the market's
advance slowed during the second half of the reporting period as turmoil in the
sub-prime mortgage market spread to other areas of the financial markets,
derailing investor confidence. The fund participated fully in the market's rise,
producing higher returns than its benchmark due to the success of our security
selection process in a variety of market sectors.

For the 12-month period ended September 30, 2007, The Boston Company Large Cap
Core Fund returned 20.3% as compared to its benchmark, the S&P 500 Index, which
returned 16.4%. The portfolio outperformed the S&P 500 Index, thanks largely to
strong stock selection in the Consumer Discretionary and Information Technology
sectors. Within Consumer Discretionary, an initial overweight in Hilton Hotels
and a consistent overweight in McDonald's helped to boost performance. We
liquidated Hilton Hotels after a private equity group offered shareholders a
significant premium to the high end of the 52-week trading range, harvesting a
return of more than 60% for the period. In the Information Technology sector, it
was the telecommunications equipment and computer hardware industries that
claimed the strongest relative performance. The superstar in the
telecommunications equipment industry was Research In Motion. The maker of the
multiple "Smartphones" experienced several successful new product launches and
increased demand for this new breed of products, which resulted in several
strong quarterly earnings reports that beat Wall Street's estimates soundly. In
the computer hardware arena, Apple also enjoyed a strong, positive response from
consumers to new product releases. This resulted in solid revenue, cash flow,
gross margin and earnings growth.

While we would prefer that all of our portfolio picks add value, we did have
several stocks that slowed performance. Within Financials, two stocks in the
capital markets industry (ETRADE Financial and Merrill Lynch) and one specialty
insurance firm (Ambac Financial Group) accounted for much of the fund's
underperformance. As expected, many financial institutions slipped during the
period on the negative sentiment surrounding this past summer's sub-prime loan
and liquidity crunch. Merrill Lynch stumbled due to investor perceptions that
there was significant sub-prime loan exposure on the company's books. However,
we feel that these views are unfounded and continue to hold the stock due to its
well-diversified revenue stream and historically-attractive valuation. ETRADE
Financial, a firm that had some exposure to mortgage loans on its books, also
suffered. While they were not forced to liquidate and realize massive losses
like some firms, they did decide to reduce loan exposure and ride out the
mortgage storm. This was not an encouraging sign and the position was
liquidated.

The fund continues to rely on the disciplined process that has produced
distinguished performance in the past. Based on our bottom-up stock selection
process, we have identified what we believe are a relatively large number of
attractive investments among technology companies. By contrast, we have reduced
the fund's exposure to consumer discretionary stocks, where we see cautionary
business trends and little earnings clarity. We have also trimmed the fund's
energy positions in light of current valuations. We believe that these
strategies should position the fund for continued, albeit slowing, economic
growth.

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

by the average account value over the period, multiplied by 183/365 (to reflect
the one-half year period).

                     The Boston Company Large Cap Core Fund

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

(1)  Organization and Significant Accounting Policies:

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

     The objective of the Fund is 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 companies that appear to be
     undervalued relative to underlying business fundamentals. The Fund focuses
     on companies with total market capitalizations which are greater than the
     market capitalization of companies in the bottom 5% of the S&P 500 Index.
     The Fund may invest without limit in securities of U.S. companies and of
     foreign companies that are listed or traded in the U.S., but not more than
     10% of it assets in other foreign securities.

     Prior to September 20, 2007, the Fund had invested substantially all of its
     investable assets in The Boston Company Large Cap Core Portfolio (the
     "Portfolio"), a subtrust of the Mellon Institutional Funds Master
     Portfolio, a New York trust. The Portfolio had investment objectives,
     policies and limitations substantially identical to those of the Fund. On
     September 19, 2007, the Fund, which had owned 100% of the Portfolio on such
     date, withdrew entirely from the Portfolio and received the Portfolio's
     assets, including securities and cash, and assumed its stated liabilities,
     in exchange for its interests in the Portfolio. This redemption in kind
     transaction was effected based upon the net assets value of the Fund's
     interests in the Portfolio. Effective September 20, 2007, the Fund began
     investing directly in securities. Accordingly, the financial statements of
     the Fund and Portfolio have been presented on a consolidated basis, and
     represent all the activities of both the Fund and the Portfolio.

     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

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. Securities are valued at the last sale prices on the exchange or
     national securities market on which they are primarily traded. Securities
     not listed on an exchange or national securities market, or securities for
     which there were no reported transactions, are valued at the last
     calculated mean price (average of last bid and last offer). Securities that
     are fixed income securities, other than short-term instruments with less
     than sixty days remaining to maturity, for which accurate market prices are
     readily available, are valued at their current market value on the basis of
     quotations, which may be furnished by a pricing service or dealers in such
     securities. Securities (including illiquid securities) for which quotations
     are not readily available, or if such quotations do not accurately reflect
     fair value, are valued at their fair value as determined in good faith
     under consistently applied procedures under the general supervision of the
     Trustees. With respect to any portion of the Fund's assets that are
     invested in one or more open-end regulated investment companies ("RICs"),
     the Fund's net asset value ("NAV") will be calculated based upon the NAVs
     of such RICs.

     Exchange traded options and futures are valued at the settlement price
     determined by the relevant exchange. Non-exchange traded derivatives are
     normally valued on the basis of quotes obtained from brokers and dealers,
     including counterparties or pricing services.

     Short-term instruments with less than sixty days remaining to maturity 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 cost based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized cost does not represent fair value.

     B. Securities transactions and income Securities

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

     C. Distributions to shareholders

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from 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 reclassifications, are primarily due to losses deferred
     due to wash sales.

     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 (loss) and accumulated net
     realized gain (loss) on investments may include temporary book and tax
     basis differences which will be distributed in a subsequent period. Any
     taxable income or gain remaining at fiscal year end is distributed in the
     following year.

     D. Expenses

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

     E. Commitments and contingencies

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

     F. Affiliated issuers

     Affiliated issuers are investment companies advised by The Boston Company
     Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of The Bank of
     New York Mellon Corporation ("BNY Mellon"), or its affiliates.

     G. New accounting requirements

     On September 20, 2006, the Financial Accounting Standards Board ("FASB")
     released Statement of Financial Accounting Standards No. 157 "Fair Value
     Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition
     of fair value, sets out a framework for measuring fair value, and requires
     additional disclosures about fair-value measurements. The application of
     FAS 157 is required for fiscal years beginning after November 15, 2007 and
     interim periods within those fiscal years. At this time, management is
     evaluating the implications of FAS 157 and its impact, if any, in the
     financial statements has not yet been determined.

(2)  Investment Advisory Fee and Other Transactions With Affiliates:

     The investment advisory fee paid to TBCAM for overall investment advisory
     and administrative services and general office facilities is paid monthly
     at the annual rate of 0.50% of the Fund's average daily net assets.

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide personnel
     and facilities to perform transfer agency and certain shareholder services
     for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a
     fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $10,838, for the year ended September 30, 2007.

     The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"),
     a wholly-owned subsidiary of BNY Mellon and an affiliate of TBCAM, to
     provide custody, administration and accounting services for the Fund. For
     these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $100,709 for the year ended September 30,
     2007.

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     The Trust entered into two separate agreements with The Bank of New York
     that enables the Fund, and other funds in the Trust, to borrow, in the
     aggregate, (i) up to $35 million from a committed line of credit and (ii)
     up to $15 million from an uncommitted line of credit. Interest is charged
     to each participating fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. The participating funds also
     pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
     uncommitted amounts and allocated ratably to the participating funds. In
     addition, a facility fee, computed at an annual rate of 0.060 of 1% on the
     committed amount, is allocated ratably among the participating funds at the
     end of each quarter. Pursuant to these agreements, the Fund was charged
     $3,393 for the year ended September 30, 2007, which amount is included in
     miscellaneous expenses on the statement of operations. See Note 7 for
     further details.

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended
     September 30, 2007, the Fund was charged $3,121, which amount is included
     in miscellaneous expenses in the statement of operations. No other
     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 Fund pays each Trustee who is not a director,
     officer or employee of TBCAM or its affiliates an annual fee and a per
     meeting fee as well as reimbursement for travel and out-of-pocket expenses.
     In addition, the Trust pays the legal fees for the independent counsel of
     the Trustees.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide printing and
     fulfillment services for the Fund. Pursuant to this agreement, the Fund was
     charged $567, which amount is included in miscellaneous expenses in the
     statement of operations, for the year ended September 30, 2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     year ended September 30, 2007, the Fund was charged $130,312 for fees
     payable to BNY Mellon Wealth Management.

     Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
     owned subsidiary of BNY Mellon and affiliate of TBCAM, replaced Mellon
     Funds Distributor, L.P. as the Fund's principal distributor.

     Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
     of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
     Mellon being the surviving entity of each merger.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended September 30, 2007 were as follows:



                                        Purchases                Sales

(4) Shares of Beneficial Interest:

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

                   Mellon Institutional Funds Investment Trust
                     The Boston Company Large Cap Core Fund

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     At September 30, 2007, two shareholders of record held in the aggregate 72%
     of the total outstanding shares of the Fund. Investment activities of these
     shareholders could have a material impact on the Fund.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     30 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2007, the Fund did not
     assess any redemption fees.

(5)  Federal Taxes:

     Each year, the Fund intends to qualify as a "regulated investment company"
     under Subchapter M of the Code. As such and by complying with the
     applicable provisions of the Code regarding the sources of its income, the
     timely distributions of its income to its shareholders, and the
     diversification of its assets, the Fund will not be subject to U.S. federal
     income tax on its investment company taxable income and net capital gain
     which are distributed to shareholders.

     In July 2006, FASB issued Interpretation No. 48, "Accounting for
     Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
     (the "Interpretation"). The Interpretation establishes for all entities,
     including pass-through entities such as the Fund, a minimum threshold for
     financial statement recognition of the benefit of positions taken in filing
     tax returns (including whether an entity is taxable in a particular
     jurisdiction), and requires certain expanded tax disclosures. Adoption of
     FIN 48 is required for fiscal years beginning after December 15, 2006 and
     is to be applied to all open tax years as of the effective date. At this
     time, management is evaluating the implications of FIN 48 and its impact on
     the financial statements has not yet been determined.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2007 were as follows:


                                                     
             Cost for federal income tax purposes        $   105,357,588

The tax character of distributions paid during the fiscal years ended September
30, 2007 and September 30, 2006, was as follows:

(6)  Financial Instruments:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved.

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

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     Futures contracts

     The Fund may enter into financial futures contracts for the purchase or
     sale of securities, or contracts based on financial indices at a fixed
     price on a future date. Pursuant to 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
     appreciation or depreciation 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 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 also arise if there is an illiquid secondary
     market or if the counterparty does not perform under the contract's terms.
     The Fund enters into financial futures transactions primarily to seek to
     manage its exposure to certain markets and to changes in securities prices
     and foreign currencies. Gains and losses are realized upon the expiration
     or closing of the futures contracts. Futures contracts are valued at the
     quoted daily settlement prices established by the exchange on which they
     trade.

     At September 30, 2007, the Fund did not hold any open financial futures
     contracts.

(7)  Line of Credit:

     On behalf of the Fund, and other funds in the Trust, the Trust has access
     to a credit facility, which enables each fund to borrow, in the aggregate,
     up to $35 million under a committed line of credit and up to $15 million
     under an uncommitted line of credit. For the year ended September 30, 2007,
     the Fund had average borrowings outstanding of $815,154 for a total of
     twenty-six days and incurred $3,410 of interest expense. At September 30,
     2007, the Fund did not have an outstanding loan balance.

             Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------

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

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of The Boston Company Large Cap Core
Fund (the "Fund") at September 30, 2007, the results of its operations for the
year then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with accounting principles generally accepted
in the United States of America. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2007 by correspondence with the
custodian, provide a reasonable basis for our opinion.

MELLON INSTITUTIONAL FUNDS

September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper typically viewed as the safest segment of the corporate market
had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth around 2% GDP growth in 2008 vs. the 2.5% long-term
trend is more likely. We see U.S. exports boosted by the weaker dollar,
multi-year global economic expansion and monetary growth, and high corporate
profitability especially for multinational franchises as being positives that
partially offset the drag of the housing sector and lower consumption.

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,
Barbara McCann
President

                  The Boston Company Small/Mid Cap Growth Fund


                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

Small/mid-cap stocks rallied early in the reporting period amid moderate
economic growth, stable short-term interest rates and rising corporate earnings.
At the time, investors maintained an ample appetite for risk, which benefited
shares of smaller companies more than their larger counterparts. However, the
market environment changed dramatically in mid-June 2007, when credit concerns
in the sub-prime mortgage sector spread to other areas of the financial markets.
In the ensuing market turbulence, newly risk-averse investors engaged in a
"flight to quality", and larger, higher-quality companies returned to favor.

The Federal Reserve Board attempted to improve market liquidity by reducing key
short-term interest rates in August and September. These moves bolstered
investor confidence that a recession could be avoided, sparking a market rally
late in the reporting period.

For the 12-month period ended September 30, 2007, The Boston Company Small/Mid
Cap Growth Fund returned 26.31% as compared to the fund's benchmark, the Russell
2500 Growth Index, which returned 21.27% over the same period. The portfolio
enjoyed strong relative returns from exposure to the Energy, Industrials,
Consumer Staples, and Healthcare sectors. Within Energy, investments in both the
equipment and services and the consumable fuels segments were strong
contributors to performance, as strong stock selection led to significantly
higher returns relative to the benchmark. Exploration and production companies
such as Range Resources, Cabot Oil & Gas, and Penn Virginia Corp. were among the
stronger performers, while equipment and services stocks FMC Technologies,
Cameron International Corp., and W-H Energy Services led this segment higher.
Healthcare also proved to be a relatively strong area for the portfolio, led by
pharmaceuticals, equipment and supplies, and providers and services.
Pharmaceuticals were driven by investments in Adams Respiratory Therapeutics and
MGI Pharma, while within equipment and supplies, we benefited from investments
in diversified diagnostic and medical device companies Cytyc Corp. and Viasys
Healthcare Inc. Industrials continued to hold up well relative to the benchmark,
benefiting from strength among our portfolio selections in the construction and
engineering, distributors, and commercial services segments. Engineering and
construction firms Foster Wheeler, Quanta services, and Washington Group
International all surged during the period, the latter of which was acquired by
URS Corporation.

Conversely, the portfolio was negatively affected by exposure to the Financials
and Information Technology sectors. With regard to Information Technology, the
portfolio's investments in the software, computers and peripherals, and
electronic equipment and instruments segments underperformed relative to the
benchmark. Software services providers Amdocs Ltd, BEA Systems and Sybase Inc.
led the relative decline in the software segment, while the portfolio also saw
declines in scalable server manufacturer Rackable Systems, component
manufacturer SMART Modular Technologies, and National Instruments Corp. Within
the Financials sector, exposure to commercial banks and capital markets segments
hurt portfolio performance as well. Commercial bank Capitol Bancorp suffered a
decline as problems in their business in Great Lakes region could not be offset
by strength in the their California business, compressing margins and hurting
their earnings. Within capital markets, investment service firms Piper Jaffray
Cos. and Jefferies Group Inc. both declined on profit concerns.

As we move into the fourth quarter, we believe that the slower U.S. economy will
continue to challenge our focus on uncovering companies that can grow in spite
of this deceleration. We, as always, are sensitive to valuation and fundamentals
that belie a company's ability to achieve and sustain growth.

** Combined Limited Partnership & Mutual Fund Performance

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

                    Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

+    Expenses are equal to the Fund's annualized expense ratio of 1.00%,
     multiplied by the average account value over the period, multiplied by
     183/365 (to reflect the one-half year period).

                  Mellon Institutional Funds Investment Trust
                  The Boston Company Small/Mid Cap Growth Fund

                         Notes to Financial Statements
- --------------------------------------------------------------------------------
(1) Organization and 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/Mid Cap Growth Fund (the "Fund") is a separate
    diversified investment series of the Trust.

    The objective of the Fund is to achieve long-term growth of capital. The
    Fund seeks to achieve its objective by investing, under normal
    circumstances, at least 80% of net assets in equity securities of small cap
    and mid cap U.S. companies. The Fund focuses on companies with total market
    capitalizations equal to or less than the total market capitalization of the
    largest company included in the Russell 2500 Growth Index. The Fund may also
    invest in equity index futures based on the Russell 2000 and S&P Midcap
    indices, and exchange traded funds based upon the Russell 2500 Growth Index.

    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

    Fund shares are valued as of the close of regular trading (normally 4:00
    p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is
    open. Securities are valued at the last sale prices on the exchange or
    national securities market on which they are primarily traded. Securities
    not listed on an exchange or national securities market, or securities for
    which there were no reported transactions, are valued at the last calculated
    mean price (average of last bid and last offer). Securities that are fixed
    income securities, other than short-term instruments with less than sixty
    days remaining to maturity, for which accurate market prices are readily
    available, are valued at their current market value on the basis of
    quotations, which may be furnished by a pricing service or dealers in such
    securities. Securities (including illiquid securities) for which quotations
    are not readily available, or if such quotations do not accurately reflect
    fair value, are valued at their fair value as determined in good faith under
    consistently applied procedures under the general supervision of the
    Trustees. With respect to any portion of the Fund's assets that are invested
    in one or more open-end regulated investment companies ("RICs"), the Funds
    net asset value ("NAV") will be calculated based upon the NAVs of such RICs.

    Exchange traded options and futures are valued at the settlement price
    determined by the relevant exchange. Non-exchange traded derivatives are
    normally valued on the basis of quotes obtained from brokers and dealers,
    including counterparties or pricing services.

    Short-term instruments with less than sixty days remaining to maturity 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 cost based upon the value
    on such date unless the Trustees determine during such sixty-day period that
    amortized cost does not represent fair value.

    B. Securities transactions and income

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

    C. Distributions to shareholders

    Distributions to shareholders are recorded on the ex-dividend date. The
    Fund's distributions from 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 reclassifications, are primarily due to losses deferred
    due to wash sales and the timing of recognition of realized and unrealized
    gains and losses on futures contracts.

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

                         Notes to Financial Statements
- --------------------------------------------------------------------------------
    D.  Expenses

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

    E.  Commitments and contingencies

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

    F.  Affiliated issuers

    Affiliated issuers are investment companies advised by The Boston Company
    Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of The Bank of New
    York Mellon Corporation ("BNY Mellon"), or its affiliates.

    G.  New accounting requirements

    On September 20, 2006, the Financial Accounting Standards Board ("FASB")
    released Statement of Financial Accounting Standards No. 157 "Fair Value
    Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition
    of fair value, sets out a framework for measuring fair value, and requires
    additional disclosures about fair-value measurements. The application of
    FAS 157 is required for fiscal years beginning after November 15, 2007 and
    interim periods within those fiscal years. At this time, management is
    evaluating the implications of FAS 157 and its impact, if any, in the
    financial statements has not yet been determined.

(2) Investment Advisory Fee and Other Transactions With Affiliates:

    The investment advisory fee paid to TBCAM for overall investment advisory,
    administrative services, and general office facilities, is paid monthly at
    the annual rate of 0.60% of the Fund's average daily net assets. TBCAM
    voluntarily agreed to limit the Fund's total annual 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, 2007. Pursuant to this arrangement, for the year ended September 30,
    2007, TBCAM voluntarily waived a portion of its investment advisory fee in
    the amount of $55,134. This arrangement is voluntary and temporary and may
    be discontinued or revised by TBCAM at any time.

    The Trust entered into an agreement with Dreyfus Transfer, Inc., a
    wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
    subsidiary of BNY Mellon and an affiliate of TBCAM, to provide personnel and
    facilities to perform transfer agency and certain shareholder services for
    the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a fixed
    fee plus per account and transaction based fees, as well as, out-of-pocket
    expenses. Pursuant to this agreement, the Fund was charged $7,511, for the
    year ended September 30, 2007.

    The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"),
    a wholly-owned subsidiary of BNY Mellon and an affiliate of TBCAM, to
    provide custody, administration and accounting services for the Fund. For
    these services the Fund pays Mellon Bank a fixed fee plus asset and
    transaction based fees, as well as out-of-pocket expenses. Pursuant to this
    agreement, the Fund was charged $67,140 for the year ended September 30,
    2007.

    The Trust also entered into an agreement with Mellon Bank to perform
    certain securities lending activities and to act as the Funds lending
    agent. Mellon Bank receives an agreed upon percentage of the net lending
    revenues. Pursuant to this agreement, Mellon Bank earned $2,923 for the
    year ended September 30, 2007. See Note 7 for further details.

    The Trust entered into two separate agreements with The Bank of New York
    that enables the Fund, and other funds in the Trust, to borrow, in the
    aggregate, (i) up to $35 million from a committed line of credit and (ii)
    up to $15 million from an uncommitted line of credit. Interest is charged
    to each participating fund based on its borrowings at a rate equal to the
    Federal Funds effective rate plus 1/2 of 1%. The participating funds also
    pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
    uncommitted amounts and allocated ratably to the participating funds. In
    addition, a facility fee, computed at an annual rate of 0.060 of 1% on the
    committed amount, is allocated ratably among the participating funds at the

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

    The Trust reimburses BNY Mellon Asset Management for a portion of the salary
    of the Trust's Chief Compliance Officer. For the year ended September 30,
    2007, the Fund was charged $4,250, which amount is included in miscellaneous
    expenses in the statement of operations. No other 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 Fund pays
    each Trustee who is not a director, officer or employee of TBCAM or its
    affiliates an annual fee and a per meeting fee as well as reimbursement for
    travel and out-of-pocket expenses. In addition, the Trust pays the legal
    fees for the independent counsel of the Trustees.

    The Trust has contracted Mellon Investor Services LLC, a wholly owned
    subsidiary of BNY Mellon and an affiliate of TBCAM, to provide printing and
    fulfillment services for the Fund. Pursuant to this agreement, the Fund was
    charged $1,828, which amount is included in miscellaneous expenses in the
    statement of operations, for the year ended September 30, 2007.

    The Fund may pay administrative service fees. These fees are paid to
    affiliated or unaffiliated retirement plans, omnibus accounts and platform
    administrators and other entities ("Plan Administrators") that provide

    retirement plans and their participants. As compensation for such services,

    an amount of up to 0.15% (on an annualized basis) of the Fund's average
    daily net assets attributable to Fund shares that are held in accounts
    serviced by such Plan Administrator. The Fund's adviser or its affiliates
    may pay additional compensation from their own resources to Plan
    Administrators and other entities for administrative services, as well as
    in consideration of marketing or other distribution-related services. These
    payments may provide an incentive for these entities to actively promote
    the Fund or cooperate with the distributor's promotional efforts. For the
    year ended September 30, 2007, the Fund was charged $1,357 for fees paid to
    BNY Mellon Wealth Management.

                         Notes to Financial Statements
- --------------------------------------------------------------------------------
(5) Federal Taxes:

    Each year, the Fund intends to qualify as a "regulated investment company"
    under Subchapter M of the Code. As such and by complying with the applicable
    provisions of the Code regarding the sources of its income, the timely
    distributions of its income to its shareholders, and the diversification of
    its assets, the Fund will not be subject to U.S. federal income tax on its
    investment company taxable income and net capital gain which are distributed
    to shareholders.

    In July 2006, FASB issued Interpretation No. 48, "Accounting for
    Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
    (the "Interpretation"). The Interpretation establishes for all entities,
    including pass-through entities such as the Fund, a minimum threshold for
    financial statement recognition of the benefit of positions taken in filing
    tax returns (including whether an entity is taxable in a particular
    jurisdiction), and requires certain expanded tax disclosures. Adoption of
    FIN 48 is required for fiscal years beginning after December 15, 2006 and
    is to be applied to all open tax years as of the effective date. At this
    time, management is evaluating the implication of FIN 48 and its impact in
    the financial statements has not yet been determined.

    The tax basis components of distributable earnings and the federal tax cost
    as of September 30, 2007 were as follows:

                                                      
             Cost for federal income tax purposes        $ 33,289,402

    The tax character of distributions paid during the fiscal years ended
    September 30, 2007 and September 30, 2006 was as follows:

(6) Financial Instruments:

    In general, the following instruments are used for hedging purposes as
    described below. However, these instruments may also be used to seek to
    enhance potential gain in circumstances where hedging is not involved.

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

    Futures contracts

    The Fund may enter into financial futures contracts for the purchase or
    sale of securities, or contracts based on financial indices at a fixed
    price on a future date. Pursuant to 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
    appreciation or depreciation 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 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 also arise if there is an illiquid secondary
    market or if the counterparty does not perform under the contract's terms.
    The Fund enters into financial futures transactions primarily to seek to
    manage its exposure to certain markets and to changes in securities prices
    and foreign currencies. Gains and losses are realized upon the expiration
    or closing of the futures contracts. Futures contracts are valued at the
    quoted daily settlement prices established by the exchange on which they
    trade.

    At September 30, 2007, the Fund held open financial futures contracts. See
    the Schedule of Investments for further details.

                         Notes to Financial Statements
- --------------------------------------------------------------------------------
(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, 2007 and
    earned interest on the invested collateral of $118,385 of which $111,528 was
    rebated to borrowers or paid in fees. At September 30, 2007, the Fund had
    securities valued at $3,726,436 on loan of which $3,858,175 was
    collateralized with cash and $10,945 was collateralized with highly liquid
    securities. See Schedule of Investments for further detail on the security
    positions on loan and collateral held.

(8) Line of Credit:

    On behalf of the the Fund, and other funds in the Trust, the Trust has
    access to a credit facility, which enables each fund to borrow, in the
    aggregate, up to $35 million under a committed line of credit and up to $15
    million under an uncommitted line of credit. For the year ended September
    30, 2007, the Fund had average borrowings outstanding of $1,200,000 for a
    total of four days and incurred $767 of interest expense. At September 30,
    2007, the Fund did not have a loan balance outstanding.

             Report of Independent Registered Public Accounting Firm

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

    In our opinion, the accompanying statement of assets and liabilities,
    including the schedule of investments, and the related statements of
    operations and of changes in net assets and the financial highlights present
    fairly, in all material respects, the financial position of The Boston
    Company Small/Mid Cap Growth Fund (the Fund) at September 30, 2007, the
    results of its operations for the year then ended, the changes in its net
    assets for each of the two years in the period then ended and the financial
    highlights for each of the five years in the period then ended, in
    conformity with accounting principles generally accepted in the United
    States of America. These financial statements and financial highlights
    (hereafter referred to as "financial statements") are the responsibility of
    the Fund's management. Our responsibility is to express an opinion on these
    financial statements based on our audits. We conducted our audits of these
    financial statements in accordance with the standards of the Public Company
    Accounting Oversight Board (United States). Those standards require that we
    plan and perform the audit to obtain reasonable assurance about whether the
    financial statements are free of material misstatement. An audit includes
    examining, on a test basis, evidence supporting the amounts and disclosures
    in the financial statements, assessing the accounting principles used and
    significant estimates made by management, and evaluating the overall
    financial statement presentation. We believe that our audits, which included
    confirmation of securities at September 30, 2007 by correspondence with the
    custodian and brokers, provide a reasonable basis for our opinion.

MELLON INSTITUTIONAL FUNDS

September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

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,
Barbara McCann
President

                   Mellon Institutional Funds Investment Trust
                    The Boston Company Small Cap Growth Fund

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

Small-cap stocks rallied early in the reporting period amid moderate economic
growth, stable short-term interest rates and rising corporate earnings. At the
time, investors maintained an ample appetite for risk, which benefited shares of
smaller companies more than their larger counterparts. However, the market
environment changed dramatically in mid-June 2007, when credit concerns in the
sub-prime mortgage sector spread to other areas of the financial markets. In the
ensuing market turbulence, newly risk-averse investors engaged in a "flight to
quality," and larger, higher-quality companies returned to favor.

The Federal Reserve Board attempted to improve market liquidity by reducing key
short-term interest rates in August and September. These moves bolstered
investor confidence that a recession could be avoided, sparking a market rally
late in the reporting period.

For the 12-month period ended September 30, 2007, The Boston Company Small Cap
Growth Fund returned 19.61% as compared to the fund's benchmark, the Russell
2000 Growth Index, which returned 18.94% over the same period. The fund enjoyed
strong relative returns from exposure to the Energy, Healthcare, Industrials,
and Materials sectors. Within Energy, investments in both the equipment and
services and the consumable fuels segments were strong contributors to
performance, as strong stock selection led to significantly higher returns
relative to the benchmark. Exploration and production companies such as Arena
Resources, Cabot Oil & Gas, and Penn Virginia Corp. were among the stronger
performers, while equipment and services stocks W-H Energy Services, T-3 Energy
Services, and Oil States led this group higher. Healthcare also proved to be a
relatively strong area for the portfolio, led by pharmaceuticals, biotechnology,
and equipment and suppliers. Sirtris Pharmaceuticals, Inc., a biopharmaceutical
company, enjoyed strong returns as the company has had success with emerging
treatments for aging and effects thereof. Within equipment and supplies, we
benefited from investments in diversified diagnostic and medical device
companies Cytyc Corp. and Viasys Healthcare Inc., as well as, biotechnology
companies Sima Therapeutics, InterMune Inc., and Sangamo BioSciences, Inc.
Industrials continued to hold up well relative to the benchmark, benefiting from
strength among our portfolio selections in the electrical equipment, commercial
services, and transportation infrastructure segments, while our Materials
investments rose sharply on continued strength in the metal commodities and
agriculture chemicals due to the ethanol push which has driven corn harvesting
to an all-time high.

Conversely, the portfolio was affected negatively by exposure to the Information
Technology and Consumer Discretionary sectors. With regard to Information
Technology, the portfolio's investments in the semiconductors, computers and
peripherals, and software segments underperformed relative to the benchmark.
Rudolph Technologies, a provider of process control metrology and data analysis
systems for the semiconductor industry, fell as weakness in demand from memory
manufacturers hurt revenues. The portfolio also saw declines in high performance
chip and software provider Ikanos Communications, scalable server manufacturer
Rackable Systems, and business software provider BEA Systems. Within the
Consumer Discretionary sector, exposure to the catalog/internet retail area hurt
on a relative basis as this was among the best performing segments within the
sector for the Index and our investments in US Auto Parts Network and Shutterfly
Inc. declined.

As we move into the fourth quarter, we believe that the slower U.S. economy will
continue to challenge our focus on uncovering companies that can grow in spite
of this deceleration. We, as always, are sensitive to valuation and fundamentals
that belie a company's ability to achieve and sustain growth.

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

                     Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

(1)    Organization and Significant Accounting Policies:

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

       The objective of the Fund is to achieve long-term growth of capital. The
       Fund seeks to achieve its objective by investing, under normal
       circumstances, at least 80% of its net assets in equity securities of
       small cap U.S. companies. The Fund focuses on companies with total market
       capitalizations equal to or less than the total market capitalization of
       the largest company included in the Russell 2000 Growth Index. The Fund
       may also invest in equity index futures contracts based primarily upon
       the Russell 2000 Index.

       Prior to September 20, 2007, the Fund had invested substantially all of
       its investable assets in The Boston Company Small Cap Growth Portfolio
       (the "Portfolio"), a subtrust of the Mellon Institutional Funds Master
       Portfolio, a New York trust. The Portfolio had investment objectives,
       policies and limitations substantially identical to those of the Fund. On
       September 19, 2007, the Fund, which had owned 100% of the Portfolio on
       such date, withdrew entirely from the Portfolio and received the
       Portfolio's assets, including securities and cash, and assumed its stated
       liabilities, in exchange for its interests in the Portfolio. This
       redemption in kind transaction was effected based upon the net assets
       value of the Fund's interest in the portfolio. Effective September 20,
       2007, the Fund began investing directly in securities. Accordingly, the
       financial statements of the Fund and Portfolio have been presented on a
       consolidated basis, and represent all the activities of both the Fund and
       the Portfolio.

       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

       Fund shares are valued as of the close of regular trading (normally 4:00
       p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
       is open. Securities are valued at the last sale prices on the exchange or
       national securities market on which they are primarily traded. Securities
       not listed on an exchange or national securities market, or securities
       for which there were no reported transactions, are valued at the last
       calculated mean price (average of last bid and last offer). Securities
       that are fixed income securities, other than short-term instruments with
       less than sixty days remaining to maturity, for which accurate market
       prices are readily available, are valued at their current market value on
       the basis of quotations, which may be furnished by a pricing service or
       dealers in such securities. 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. With respect to any
       portion of the Fund's assets that are invested in one or more open-end
       regulated investment companies ("RICs"), the Fund's net asset value
       ("NAV") will be calculated based upon the NAVs of such RICs.

       Exchange traded options and futures are valued at the settlement price
       determined by the relevant exchange. Non-exchange traded derivatives are
       normally valued on the basis of quotes obtained from brokers and dealers,
       including counterparties or pricing services.

       Short-term instruments with less than sixty days remaining to maturity
       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 cost based
       upon the value on such date unless the Trustees determine during such
       sixty-day period that amortized cost does not represent fair value.

       B. Securities transactions and income

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

       C. Distributions to shareholders

       Distributions to shareholders are recorded on the ex-dividend date. The
       Fund's distributions from 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 reclassifications, are primarily due to losses
       deferred due to wash sales, capital loss carryovers and the timing of
       recognition of realized and unrealized gains and losses on futures
       contracts.

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

       D. Expenses

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

       E. Commitments and contingencies

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

       F. Affiliated issuers

       Affiliated issuers are investment companies advised by The Boston Company
       Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of The Bank of
       New York Mellon Corporation ("BNY Mellon"), or its affiliates.

       G. New Accounting Requirements

       On September 20, 2006, the Financial Accounting Standards Board ("FASB")
       released Statement of Financial Accounting Standards No. 157 "Fair Value
       Measurements" ("FAS 157"). FAS 157 establishes an authoritative
       definition of fair value, sets out a framework for measuring fair value,
       and requires additional disclosures about fair-value measurements. The
       application of FAS 157 is required for fiscal years beginning after
       November 15, 2007 and interim periods within those fiscal years. At this
       time, management is evaluating the implications of FAS 157 and its
       impact, if any, in the financial statements has not yet been determined.

(2)    Investment Advisory Fee and Other Transactions With Affiliates:

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

       The Trust entered into an agreement with Dreyfus Transfer, Inc., a
       wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
       subsidiary of BNY Mellon and an affiliate of TBCAM, to provide personnel
       and facilities to perform transfer agency and certain shareholder
       services for the Fund. For these services the Fund pays Dreyfus Transfer,
       Inc. a fixed fee plus per account and transaction based fees, as well as,
       out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
       $11,331, for the year ended September 30, 2007.

       The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon
       Bank"), a wholly-owned subsidiary of BNY Mellon and an affiliate of
       TBCAM, to provide custody, administration and accounting services for the
       Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset
       and transaction based fees, as well as out-of-pocket expenses. Pursuant
       to this agreement, the Fund was charged $138,073 for the year ended
       September 30, 2007.

       The Trust also entered into an agreement with Mellon Bank to perform
       certain securities lending activities and to act as the Fund's lending
       agent. Mellon Bank receives an agreed upon percentage of the net lending
       revenues. Pursuant to this agreement, the Fund was charged $52,515 for
       the year ended September 30, 2007. See Note 7 for further details.

       The Trust entered into two separate agreements with The Bank of New York
       that enables the Fund, and other funds in the Trust, to borrow, in the
       aggregate, (i) up to $35 million from a committed line of credit and (ii)
       up to $15 million from an uncommitted line of credit. Interest is charged
       to each participating fund based on its borrowings at a rate equal to the
       Federal Funds effective rate plus 1/2 of 1%. The participating funds also
       pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
       uncommitted amounts and allocated ratably to the participating funds. In
       addition, a facility fee, computed at an annual rate of 0.060 of 1% on
       the committed amount, is allocated ratably among the participating funds
       at the end of each quarter. Pursuant to these agreements, the Fund was
       charged $188 for the year ended September 30, 2007, which amount is
       included in miscellaneous expenses on the statement of operations. See
       Note 8 for further details.

       The Trust reimburses BNY Mellon Asset Management for a portion of the
       salary of the Trust's Chief Compliance Officer. For the year ended
       September 30, 2007, the Fund was charged $4,250, which amount is included
       in miscellaneous expenses in the statement of operations. No other
       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 Fund pays each Trustee who is not a director,
       officer or employee of TBCAM or its affiliates an annual fee and a per
       meeting fee as well as reimbursement for travel and out-of-pocket
       expenses. In addition, the Trust pays the legal fees for the independent
       counsel of the Trustees.

       The Trust has contracted Mellon Investor Services LLC, a wholly owned
       subsidiary of BNY Mellon and an affiliate of TBCAM, to provide printing
       and fulfillment services for the Fund. Pursuant to this agreement, the
       Fund was charged $3,780, which amount is included in miscellaneous
       expenses in the statement of operations, for the year ended September 30,
       2007.

       The Fund may pay administrative service fees. These fees are paid to
       affiliated or unaffiliated retirement plans, omnibus accounts and
       platform administrators and other entities ("Plan Administrators") that
       provide record keeping and/or other administrative support services to
       accounts, retirement plans and their participants. As compensation for
       such services, the Fund may pay each Plan Administrator an administrative
       service fee in an amount of up to 0.15% (on an annualized basis) of the
       Fund's average daily net assets attributable to Fund shares that are held
       in accounts serviced by such Plan Administrator. The Fund's adviser or
       its affiliates may pay additional compensation from their own resources
       to Plan Administrators and other entities for administrative services, as
       well as in consideration of marketing or other distribution-related
       services. These payments may provide an incentive for these entities to
       actively promote the Fund or cooperate with the distributor's promotional
       efforts. For the year ended September 30, 2007, the Fund was charged
       $15,210 for fees payable to BNY Mellon Private Wealth Management.

       Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
       owned subsidiary of BNY Mellon and affiliate of TBCAM, replaced Mellon
       Funds Distributor, L.P. as the Fund's principal distributor.

       Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
       of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
       Mellon being the surviving entity of each merger.

(3)    Purchases and Sales of Investments:

       Purchases and proceeds from sales of investments, other than short-term
       obligations, for the year ended September 30, 2007 were as follows:



                                                Purchases              Sales

(4)    Shares of Beneficial Interest:

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



                                              For the               For the

       At September 30, 2007, three shareholders of record held in the aggregate
       63.5% of the total outstanding shares of the Fund. Investment activities
       of these shareholders could have a material impact on the Fund.

       The Fund imposes a redemption fee of 2% of the net asset value of the
       shares, with certain exceptions, which are redeemed or exchanged less
       than 30 days from the day of their purchase. The redemption fee is paid
       directly to the Fund, and is designed to offset brokerage commissions,
       market impact, and other costs associated with short-term trading in the
       Fund. The fee does not apply to shares that were acquired through
       reinvestment of distributions. For the year ended September 30, 2007, the
       Fund received $9,445 in redemption fees which are reflected in the cost
       of shares redeemed.

                          Notes to Financial Statements

(5)    Federal Taxes:

       Each year, the Fund intends to qualify as a "regulated investment
       company" under Subchapter M of the Code. As such and by complying with
       the applicable provisions of the Code regarding the sources of its
       income, the timely distributions of its income to its shareholders, and
       the diversification of its assets, the Fund will not be subject to U.S.
       federal income tax on its investment company taxable income and net
       capital gain which are distributed to shareholders.

       In July 2006, FASB issued Interpretation No. 48, "Accounting for
       Uncertainty in Income Taxes - an Interpretation of FASB Statement No.
       109" (the "Interpretation"). The Interpretation establishes for all
       entities, including pass-through entities such as the Fund, a minimum
       threshold for financial statement recognition of the benefit of positions
       taken in filing tax returns (including whether an entity is taxable in a
       particular jurisdiction), and requires certain expanded tax disclosures.
       Adoption of FIN 48 is required for fiscal years beginning after December
       15, 2006 and is to be applied to all open tax years as of the effective
       date. At this time, management is evaluating the implication of FIN 48
       and its impact in the financial statements has not yet been determined.

       The tax basis components of distributable earnings and the federal tax
       cost as of September 30, 2007 were as follows:


                                                         
               Cost for federal income tax purposes         $228,047,067
                                                            ============
               Gross unrealized appreciation                $ 15,080,325
               Gross unrealized depreciation                  (3,051,602)
                                                            ------------
               Net unrealized appreciation (depreciation)   $ 12,028,723
                                                            ============


       At September 30, 2007, 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 investment, 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
                ----------                   ---------------
                                          
                $  384,833                      9/30/2010
                $2,296,326                      9/30/2011


       It is uncertain whether the Fund will be able to realize the benefits of
       the losses before they expire.

       For the year ended September 30, 2007, the Fund utilized $6,562,115 in
       capital loss carry forwards.

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

       Futures contracts

       The Fund may enter into financial futures contracts for the purchase or
       sale of securities, or contracts based on financial indices at a fixed
       price on a future date. Pursuant to 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 appreciation or depreciation 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 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
       also arise if there is an illiquid secondary market or if the
       counterparty does not perform under the contract's terms. The Fund enters
       into financial futures transactions primarily to seek to manage its
       exposure to certain markets and to changes in securities prices and
       foreign currencies. Gains and losses are realized upon the expiration or
       closing of the futures contracts. Futures contracts are valued at the
       quoted daily settlement prices established by the exchange on which they
       trade.

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

       At September 30, 2007, the Fund held open financial futures contracts.
       See the Schedule of Investments for further details.

(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, 2007 and
       earned interest on the invested collateral of $1,173,473 of which
       $1,050,724 was rebated to borrowers or paid in fees. At September 30,
       2007, the Fund had securities valued at $39,905,520 on loan. See Schedule
       of Investments for further detail on the security positions on loan and
       collateral held.

(8)    Line of Credit:

       On behalf of the Fund and other funds in the Trust, the Trust has access
       to a credit facility, which enables each fund to borrow, in the
       aggregate, up to $35 million under a committed line of credit and up to
       $15 million under an uncommitted line of credit.

       For the year ended September 30, 2007, the Fund did not borrow from the
       line of credit.

             Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------

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

       In our opinion, the accompanying statement of assets and liabilities,
       including the schedule of investments, and the related statements of
       operations and of changes in net assets and the financial highlights
       present fairly, in all material respects, the financial position of The
       Boston Company Small Cap Growth Fund (the "Fund") at September 30, 2007,
       the results of its operations for the year then ended, the changes in its
       net assets for each of the two years in the period then ended and the
       financial highlights for each of the five years in the period then ended,
       in conformity with accounting principles generally accepted in the United
       States of America. These financial statements and financial highlights
       (hereafter referred to as "financial statements") are the responsibility
       of the Fund's management. Our responsibility is to express an opinion on
       these financial statements based on our audits. We conducted our audits
       of these financial statements in accordance with the standards of the
       Public Company Accounting Oversight Board (United States). Those
       standards require that we plan and perform the audit to obtain reasonable
       assurance about whether the financial statements are free of material
       misstatement. An audit includes examining, on a test basis, evidence
       supporting the amounts and disclosures in the financial statements,
       assessing the accounting principles used and significant estimates made
       by management, and evaluating the overall financial statement
       presentation. We believe that our audits, which included confirmation of
       securities at September 30, 2007 by correspondence with the custodian and
       brokers, provide a reasonable basis for our opinion.

September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

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,
Barbara McCann
President

             The Boston Company Small Cap Tax-Sensitive Equity Fund

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

Small-cap stocks rallied early in the reporting period amid moderate economic
growth, stable short-term interest rates and rising corporate earnings. At the
time, investors maintained an ample appetite for risk, which benefited shares of
smaller companies more than their larger counterparts. However, the market
environment changed dramatically in mid-June 2007, when credit concerns in the
sub-prime mortgage sector spread to other areas of the financial markets. In the
ensuing market turbulence, newly risk-averse investors engaged in a "flight to
quality," and larger, higher-quality companies returned to favor.

The Federal Reserve Board attempted to improve market liquidity by reducing key
short-term interest rates in August and September. These moves bolstered
investor confidence that a recession could be avoided, sparking a market rally
late in the reporting period.

For the 12-month period ended September 30, 2007, The Boston Company Small Cap
Tax-Sensitive Equity Fund returned 20.79% as compared to the fund's benchmark,
the Russell 2000 Growth Index, which returned 18.94% over the same period. The
portfolio enjoyed strong relative returns from exposure to the Energy,
Healthcare, Industrials, and Materials sectors. Within Energy, investments in
both the equipment and services and the consumable fuels segments were strong
contributors to performance, as strong stock selection led to significantly
higher returns relative to the benchmark. Exploration and production companies
such as Arena Resources, Cabot Oil & Gas, and Penn Virginia Corp. were among the
stronger performers, while equipment and services stocks W-H Energy Services,
T-3 Energy Services, and Oil States led this group higher. Healthcare also
proved to be a relatively strong area for the portfolio, led by pharmaceuticals,
biotechnology, and equipment and suppliers. Sirtris Pharmaceuticals, Inc., a
biopharmaceutical company, enjoyed strong returns as the company has had success
with emerging treatments for aging and effects thereof. Within equipment and
supplies, we benefited from investments in diversified diagnostic and medical
device companies Cytyc Corp. and Viasys Healthcare Inc., as well as,
biotechnology companies Sima Therapeutics, InterMune Inc., and Sangamo
BioSciences, Inc. Industrials continued to hold up well relative to the
benchmark, benefiting from strength among our portfolio selections in the
electrical equipment, commercial services, and transportation infrastructure
segments, while our Materials investments rose sharply on continued strength in
the metal commodities and agriculture chemicals due to the ethanol push which
has driven corn harvesting to an all-time high.

Conversely, the portfolio was negatively affected by exposure to the Information
Technology and Consumer Discretionary sectors. With regard to Information
Technology, the portfolio's investments in the semiconductors, computers and
peripherals, and software segments underperformed relative to the benchmark.
Rudolph Technologies, a provider of process control metrology and data analysis
systems for the semiconductor industry, fell as weakness in demand from memory
manufacturers hurt revenues. The

portfolio also saw declines in high performance chip and software provider
Ikanos Communications, scalable server manufacturer Rackable Systems, and
business software provider BEA Systems. Within the Consumer Discretionary
sector, exposure to the catalog/internet retail area hurt on a relative basis as
this was among the best performing segments within the sector for the Index and
our investments in US Auto Parts Network and Shutterfly Inc. declined.

As we move into the fourth quarter, we believe that the slower U.S. economy will
continue to challenge our focus on uncovering companies that can grow in spite
of this deceleration. We, as always, are sensitive to valuation and fundamentals
that belie a company's ability to achieve and sustain growth.

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

             The Boston Company Small Cap Tax-Sensitive Equity Fund

                     Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

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

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

(1)  Organization and Significant Accounting Policies:

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

     The objective of the Fund is to maximize after-tax total return, consisting
     of long-term growth of capital. The Fund seeks to achieve its objective by
     investing, under normal circumstances, at least 80% of net assets in equity
     securities of small capitalization U.S. companies. The Fund considers small
     cap companies to have total market capitalizations equal to or less than
     the total market capitalization of the largest company included in the
     Russell 2000 Growth Index. The Fund may also invest in equity index futures
     contracts based primarily upon the Russell 2000 Index.

     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

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. Securities are valued at the last sale prices on the exchange or
     national securities market on which they are primarily traded. Securities
     not listed on an exchange or national securities market, or securities for
     which there were no reported transactions, are valued at the last
     calculated mean price (average of last bid and last offer). Securities that
     are fixed income securities, other than short-term instruments with less
     than sixty days remaining to maturity, for which accurate market prices are
     readily available, are valued at their current market value on the basis of
     quotations, which may be furnished by a pricing service or dealers in such
     securities. Securities (including illiquid securities) for which quotations
     are not readily available, or if such quotations do not accurately reflect
     fair value, are valued at their fair value as determined in good faith
     under consistently applied procedures under the general supervision of the
     Trustees. With respect to any portion of the Fund's assets that are
     invested in one or more open-end regulated investment companies ("RICs"),
     the Fund's net asset value ("NAV") will be calculated based upon the NAVs
     of such RICs.

     Exchange traded options and futures are valued at the settlement price
     determined by the relevant exchange. Non-exchange traded derivatives are
     normally valued on the basis of quotes obtained from brokers and dealers,
     including counterparties or pricing services.

     Short-term instruments with less than sixty days remaining to maturity 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 cost based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized cost does not represent fair value.

     B. Securities transactions and income

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

     C. Distributions to shareholders

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from 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 reclassifications, are primarily due to wash sales and
     the timing of recognition of realized and unrealized gains and losses on
     futures contracts.

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

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     D. Expenses

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

     E. Commitments and contingencies

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

     F. Affiliated issuers

     Affiliated issuers are investment companies advised by The Boston Company
     Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of The Bank of
     New York Mellon Corporation ("BNY Mellon"), or its affiliates.

     G. New accounting requirements

     On September 20, 2006, the Financial Accounting Standards Board ("FASB")
     released Statement of Financial Accounting Standards No. 157 "Fair Value
     Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition
     of fair value, sets out a framework for measuring fair value, and requires
     additional disclosures about fair-value measurements. The application of
     FAS 157 is required for fiscal years beginning after November 15, 2007 and
     interim periods within those fiscal years. At this time, management is
     evaluating the implications of FAS 157 and its impact, if any, in the
     financial statements has not yet been determined.

(2)  Investment Advisory Fee and Other Transactions With Affiliates:

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

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide personnel
     and facilities to perform transfer agency and certain shareholder services
     for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a
     fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $12,680, for the year ended September 30, 2007.

     The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"),
     a wholly-owned subsidiary of BNY Mellon and an affiliate of TBCAM, to
     provide custody, administration and accounting services for the Fund. For
     these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $170,199 for the year ended September 30,
     2007.

     The Trust also entered into an agreement with Mellon Bank to perform
     certain securities lending activities and to act as the Fund's lending
     agent. Mellon Bank receives an agreed upon percentage of the net lending
     revenues. Pursuant to this agreement, the Fund earned $103,656 for the year
     ended September 30, 2007. See Note 7 for further details.

     The Trust entered into two separate agreements with The Bank of New York
     that enables the Fund, and other funds in the Trust, to borrow, in the
     aggregate, (i) up to $35 million from a committed line of credit and (ii)
     up to $15 million from an uncommitted line of credit. Interest is charged
     to each participating fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. The participating funds also
     pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
     uncommitted amounts and allocated ratably to the participating funds. In
     addition, a facility fee, computed at an annual rate of 0.060 of 1% on the
     committed amount, is allocated ratably among the participating funds at the
     end of each quarter. Pursuant to these agreements, the Fund was charged
     $540 for the year ended September 30, 2007, which amount is included in
     miscellaneous expenses on the statement of operations.

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended
     September 30, 2007, the Fund was charged $4,249, which amount is included
     in miscellaneous expenses in the statement of operations. No other
     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 Fund 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.

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide printing and
     fulfillment services for the Fund. Pursuant to this agreement, the Fund was
     charged $5,122, which amount is included in miscellaneous expenses in the
     statement of operations, for the year ended September 30, 2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     year ended September 30, 2007, the Fund was charged $58,850 for fees
     payable to BNY Mellon Private Wealth Management.

     Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
     owned subsidiary of BNY Mellon and affiliate of TBCAM, replaced Mellon
     Funds Distributor, L.P. as the Fund's principal distributor.

     Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
     of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
     Mellon being the surviving entity of each merger.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended September 30, 2007 were as follows:



                                                    Purchases                  Sales
                                                  ------------             ------------

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


(4)  Shares of Beneficial Interest:

     At September 30, 2007, two shareholders of record held in the aggregate
     65.8% of the total outstanding shares of the Fund. Investment activities of
     these shareholders could have a material impact on the Fund.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     30 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2007, the Fund did not
     assess any redemption fees.

(5)  Federal Taxes:

     Each year, the Fund intends to qualify as a "regulated investment company"
     under Subchapter M of the Code. As such and by complying with the
     applicable provisions of the Code regarding the sources of its income, the
     timely distributions of its income to its shareholders, and the
     diversification of its assets, the Fund will not be subject to U.S. federal
     income tax on its investment company taxable income and net capital gain
     which are distributed to shareholders.

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     In July 2006, FASB issued Interpretation No. 48, "Accounting for
     Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
     (the "Interpretation"). The Interpretation establishes for all entities,
     including pass-through entities such as the Fund, a minimum threshold for
     financial statement recognition of the benefit of positions taken in filing
     tax returns (including whether an entity is taxable in a particular
     jurisdiction), and requires certain expanded tax disclosures. Adoption of
     FIN 48 is required for fiscal years beginning after December 15, 2006 and
     is to be applied to all open tax years as of the effective date. At this
     time, management is evaluating the implication of FIN 48 and its impact on
     the financial statements has not yet been determined.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2007 were as follows:

(6)  Financial Instruments:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved.

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

     Futures contracts

     The Fund may enter into financial futures contracts for the purchase or
     sale of securities, or contracts based on financial indices at a fixed
     price on a future date. Pursuant to 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
     appreciation or depreciation 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 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 also arise if there is an illiquid secondary
     market or if the counterparty does not perform under the contract's terms.
     The Fund enters into financial futures transactions primarily to seek to
     manage its exposure to certain markets and to changes in securities prices
     and foreign currencies. Gains and losses are realized upon the expiration
     or closing of the futures contracts. Futures contracts are valued at the
     quoted daily settlement prices established by the exchange on which they
     trade.

     At September 30, 2007, the Fund held open financial futures contracts. See
     the Schedule of Investments for further details.

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

(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, 2007 and
     earned interest on the invested collateral of $2,790,013 of which
     $2,547,291 was rebated to borrowers or paid in fees. At September 30, 2007,
     the Fund had securities valued at $70,258,013 on loan, of which $73,517,496
     was collateralized with cash and $17,655 was collateralized with highly
     liquid securities. See Schedule of Investments for further detail on the
     security positions on loan and collateral held.

             Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------

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

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of The Boston Company Small Cap
Tax-Sensitive Equity Fund (the "Fund") at September 30, 2007, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and the financial highlights for each of
the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at September 30, 2007 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

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,
Barbara McCann
President

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

Small-cap stocks rallied early in the reporting period amid moderate economic
growth, stable short-term interest rates and rising corporate earnings. At the
time, investors maintained an ample appetite for risk, which benefited shares of
smaller companies more than their larger counterparts. However, the market
environment changed dramatically in mid-June 2007, when credit concerns in the
sub-prime mortgage sector spread to other areas of the financial markets. In the
ensuing market turbulence, newly risk-averse investors engaged in a "flight to
quality," and larger, higher-quality companies returned to favor.

The Federal Reserve Board attempted to improve market liquidity by reducing key
short-term interest rates in August and September. These moves bolstered
investor confidence that a recession could be avoided, sparking a market rally
late in the reporting period.

For the 12-month period ended September 30, 2007, The Boston Company Small Cap
Value Fund returned 11.18% as compared to the fund's benchmark, the Russell 2000
Value Index, which returned 6.09% over the same period. The fund participated to
a substantial degree in the small-cap market's advance. The fund achieved
particularly strong results among information technology companies, including
electron microscope semiconductors maker FEI Company, which gained greater
penetration of nanotechnology markets, and Microsemi Corp., which continues to
see strong growth in demand for its high performance analog chip. A number of
other semiconductor companies in the fund's portfolio also produced strong
returns during the reporting period. In the communications equipment industry
group, the fund scored successes with consumer networking equipment manufacturer
Netgear and telecommunications and military networking specialist Comtech
Telecommunications.

In the health care sector, home care services provider OptionCare was acquired
by pharmacy chain Walgreen, and medical helicopter services contractor Air
Methods captured a larger share of hospital and municipal markets. The energy
sector led the benchmark's performance during the reporting period, and the fund
participated in its strength through holdings such as oil well drilling
equipment maker Hydrill, which was acquired by energy services company Quanta
Services, and oil and gas operations specialty service provider CARBO Ceramics,
which boosted earnings after adding to manufacturing capacity. Among industrial
companies, engineering and construction firm Infrasource Services benefited from
increased investment in power transmission facilities, and Shaw Group gained
value in an improved global environment for the construction of nuclear power
plants as more nations develop alternatives to fossil fuels. Conversely, some
holdings and industry groups detracted from the fund's performance during the
reporting period. For example, regional electric utility PNM Resources was
unable to pass along higher commodity costs to its customers, and the fund's
underweighted position in the materials sector prevented it from participating
fully in the sector's strength as compared to the benchmark.

                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

Although our "bottom-up" investment process does not consider macroeconomic
trends directly, we are aware that the U.S. economy is in the later stages of
its cycle and some market indices recently have set new record highs. In our
judgment, our relatively cautious, value-oriented approach to security selection
is well positioned for this environment, as it places a high degree of emphasis
on characteristics of individual companies such as solid business fundamentals,
healthy balance sheets and the ability to generate cash consistently. We
recently have found fewer opportunities meeting our criteria among industrial
companies, which have reached fuller valuations, and more in the information
technology, health care and consumer discretionary areas, which have offered
better values after extended periods of underperformance.

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund's dividends from income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

                     Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

(1)  Organization and Significant Accounting Policies:

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

     The 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. The Fund focuses on companies with total market
     capitalizations equal to or less than the total market capitalization of
     the largest company included in the Russell 2000 Index.

     Prior to September 20, 2007, the Fund had invested substantially all of its
     investable assets in The Boston Company Small Cap Value Portfolio (the
     "Portfolio"), a subtrust of the Mellon Institutional Funds Master
     Portfolio, the "Portfolio Trust", a New York trust. The Portfolio had
     investment objectives, policies, limitations and accounting policies
     substantially identical to those of the Fund. While investing in the
     Portfolio, the Fund earned its proportionate share of the Portfolio's
     income, expenses, and realized and unrealized gains and losses based on its
     percentage ownership of the Portfolio's shares of beneficial interest. The
     Portfolio's Statement of Operations for the period October 1, 2006 through
     September 19, 2007 is included in Note 9. On September 19, 2007, the Fund,
     which owned 100% of the Portfolio on that date, withdrew entirely from the
     Portfolio and received the Portfolio's assets, including securities and
     cash, and assumed the Portfolio's stated liabilities in exchange for its
     interest in the Portfolio. Effective September 20, 2007, the Fund began
     investing directly in the securities in which the Portfolio had invested.

     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

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. Securities are valued at the last sale price on the exchange or
     national securities market on which they are primarily traded. Securities
     not listed on an exchange or national securities market, or securities for
     which there were no reported transactions, are valued at the last
     calculated mean price (average of last bid and last offer). Securities that
     are fixed income securities, other than short-term instruments with less
     than sixty days remaining to maturity, for which accurate market prices are
     readily available, are valued at their current market value on the basis of
     quotations, which may be furnished by a pricing service or dealers in such
     securities. Securities (including illiquid securities) for which quotations
     are not readily available, or if such quotations do not accurately reflect
     fair value, are valued at their fair value as determined in good faith
     under consistently applied procedures under the general supervision of the
     Trustees. With respect to any portion of the Fund's assets that are
     invested in one or more open-end regulated investment companies ("RICs"),
     the Fund's net asset value ("NAV") is calculated based upon the NAVs of
     such RICs.

     Exchange traded options and futures are valued at the settlement price
     determined by the relevant exchange. Non-exchange traded derivatives are
     normally valued on the basis of quotes obtained from brokers and dealers,
     including counterparties or pricing services.

     Short-term instruments with less than sixty days remaining to maturity 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 cost based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized cost does not represent fair value.

     B. Securities transactions and income

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of coupon interest accrued, adjusted for accretion
     of discount or amortization of premium using the yield-to-maturity method
     on debt securities with greater than sixty days remaining to maturity.
     Dividend income is recorded on the ex-dividend date. Dividends representing
     a return of capital are reflected as a reduction of cost. Realized gains
     and losses from securities sold are recorded on the identified cost basis.
     Income, expenses and realized and unrealized gains and losses allocated
     from the Portfolio represent the Fund's proportionate share of those items
     earned by the Portfolio during the period October 1, 2006 through September
     19, 2007.

     C. Distributions to shareholders

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from 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.

                   Mellon Institutional Funds Investment Trust
                    The Boston Company Small Cap Value Fund

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     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 reclassifications, are primarily due to wash sales, real
     estate investment trusts and the timing of recognition of realized and
     unrealized gains and losses on futures contracts.

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

     On July 31, 2007, the Dreyfus Premier Small Cap Equity Fund ("Dreyfus
     Feeder") withdrew from the master feeder structure via a redemption-in-kind
     and received currency and securities with unrealized appreciation of
     $651,693 for the value of their interest in the Portfolio. The Fund
     realized no gain on this transaction. $1,301,484 of unrealized appreciation
     had been allocated to that feeder fund. The Fund decreased paid in capital
     and increased unrealized appreciation on investments by $649,791 to
     recognize this difference. When realized, this amount will be recognized by
     the Fund. This reclassification had no impact on the net assets or results
     of operations of the Fund.

     D. Expenses

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

     E. Commitments and contingencies

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

     F. Affiliated issuers

     Affiliated issuers are investment companies advised by The Boston Company
     Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of The Bank of
     New York Mellon Corporation ("BNY Mellon"), or its affiliates.

     G. New accounting requirements

     On September 20, 2006, the Financial Accounting Standards Board ("FASB")
     released Statement of Financial Accounting Standards No. 157 "Fair Value
     Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition
     of fair value, sets out a framework for measuring fair value, and requires
     additional disclosures about fair-value measurements. The application of
     FAS 157 is required for fiscal years beginning after November 15, 2007 and
     interim periods within those fiscal years. At this time, management is
     evaluating the implications of FAS 157 and its impact, if any, in the
     financial statements has not yet been determined.

(2)  Investment Advisory Fee and Other Transactions With Affiliates:

     Prior to September 20, 2007 the Fund did not directly incur any investment
     advisory, custody, administration and commitment fees, which were incurred
     by the Portfolio and allocated to the Fund based on its proportionate
     interest in the Portfolio. The following disclosures relating to these fees
     represent fees incurred by the Portfolio for the period prior to September
     20, 2007, and by the Fund thereafter.

     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, and previously the Portfolio's
     average daily net assets.

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide personnel
     and facilities to perform transfer agency and certain shareholder services
     for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a
     fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $37,087, for the year ended September 30, 2007.

     The Trust and previously the Portfolio Trust, entered into an agreement
     with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of BNY
     Mellon and an affiliate of TBCAM, to provide custody, administration and
     accounting services for the Portfolio/Fund. For these services the
     Portfolio/Fund pays Mellon Bank a fixed fee plus asset and transaction
     based fees, as well as out-of-pocket expenses. Pursuant to this agreement,
     the Fund was charged $188,462 for the period October 1, 2006 to September
     19, 2007 and $5,877 for the period September 20, 2007 to September 30,
     2007.

     The Trust and previously the Portfolio Trust, also entered into an
     agreement with Mellon Bank to perform certain securities lending activities
     and to act as the Portfolio/Fund's lending agent. Mellon Bank receives an
     agreed upon percentage of the net lending revenues. Pursuant to this
     agreement, Mellon Bank earned $276,543 for the period October 1, 2006 to
     September 19, 2007 and $43,829 for the period September 20, 2007 to
     September 30, 2007. See Note 7 for further details.

     The Trust and previously the Portfolio Trust, entered into two separate
     agreements with The Bank of New York that enable the Fund, and other funds
     in the Trust, to borrow, in the aggregate, (i) up to $35 million from a
     committed line of credit and (ii) up to $15 million from an uncommitted
     line of credit. Interest is charged to each participating fund based on its
     borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
     1%. The participating funds also pay an annual fee, computed at a rate of
     0.020 of 1% of the committed and uncommitted amounts and allocated ratably
     to the participating funds. In addition, a facility fee, computed at an
     annual rate of 0.060 of 1% on the committed amount, is allocated ratably
     among the participating funds at the end of each quarter. Pursuant to these
     agreements, the Fund was charged $3,669 for the period October 1, 2006 to
     September 19, 2007 and $104 for the period September 20, 2007 to September
     30, 2007, which is included in miscellaneous expenses on the statement of
     operations. See Note 8 for further details.

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended
     September 30, 2007, the Fund was charged $4,241, which amount is included
     in miscellaneous expenses in the statement of operations. No other
     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 Fund pays each Trustee who is not a director,
     officer or employee of TBCAM or its affiliates an annual fee and a per
     meeting fee as well as reimbursement for travel and out-of-pocket expenses.
     In addition, the Trust pays the legal fees for the independent counsel of
     the Trustees.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide printing and
     fulfillment services for the Fund. Pursuant to this agreement, the Fund was
     charged $13,019, which amount is included in miscellaneous expenses in the
     statement of operations, for the year ended September 30, 2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     year ended September 30, 2007, the Fund was charged $97,276 for fees
     payable to BNY Mellon Wealth Management.

     Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
     owned subsidiary of BNY Mellon and affiliate of TBCAM, replaced Mellon
     Funds Distributor, L.P. as the Fund's principal distributor.

     Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The Bank
     of New York Company, Inc. ("BNY") each merged into BNY Mellon, with BNY
     Mellon being the surviving entity of each merger.

(3)  Purchases and Sales of Investments:

                   Mellon Institutional Funds Investment Trust
                    The Boston Company Small Cap Value Fund

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     At September 30, 2007, two shareholders of record held in the aggregate
     31.1% of the total outstanding shares of the Fund. Investment activities of
     these shareholders could have a material impact on the Fund.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     30 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that were acquired through reinvestment of
     distributions. For the year ended September 30, 2007, the Fund received
     $28,716 in redemption fees.

(5)  Federal Taxes:

     Each year, the Fund intends to qualify as a "regulated investment company"
     under Subchapter M of the Internal Revenue Code ("Code"). As such and by
     complying with the applicable provisions of the Code regarding the sources
     of its income, the timely distributions of its income to its shareholders,
     and the diversification of its assets, the Fund will not be subject to U.S.
     federal income tax on its investment company taxable income and net capital
     gain which are distributed to shareholders.

     In July 2006, FASB issued Interpretation No. 48, "Accounting for
     Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
     (the "Interpretation"). The Interpretation establishes for all entities,
     including pass-through entities such as the Fund, a minimum threshold for
     financial statement recognition of the benefit of positions taken in filing
     tax returns (including whether an entity is taxable in a particular
     jurisdiction), and requires certain expanded tax disclosures. Adoption of
     FIN 48 is required for fiscal years beginning after December 15, 2006 and
     is to be applied to all open tax years as of the effective date. At this
     time, management is evaluating the implications of FIN 48 and its impact on
     the financial statements has not yet been determined.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2007 were as follows:

(6)  Financial Instruments:

     In general, the following instruments are used for hedging purposes as
     described below. However, these instruments may also be used to seek to
     enhance potential gain in circumstances where hedging is not involved.

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

     Futures contracts

     The Fund, and previously the Portfolio, may enter into financial futures
     contracts for the purchase or sale of securities, or contracts based on
     financial indices at a fixed price on a future date. Pursuant to 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 appreciation or depreciation 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

                   Mellon Institutional Funds Investment Trust

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

     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 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 also arise if there is an illiquid secondary
     market or if the counterparty does not perform under the contract's terms.
     The Fund enters into financial futures transactions primarily to seek to
     manage its exposure to certain markets and to changes in securities prices
     and foreign currencies. Gains and losses are realized upon the expiration
     or closing of the futures contracts. Futures contracts are valued at the
     quoted daily settlement prices established by the exchange on which they
     trade.

     At September 30, 2007, the Fund held open financial futures contracts. See
     the Schedule of Investments for further details.

(7)  Security Lending:

     The Fund, and previously the Portfolio, 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, and previously the Portfolio, loaned securities during the year
     ended September 30, 2007 and earned interest on the invested collateral of
     $8,706,327 of which $8,385,955 was rebated to borrowers or paid in fees. At
     September 30, 2007, the Fund had securities valued at $182,538,423 on loan.
     See Schedule of Investments for further detail on the security positions on
     loan and collateral held.

(8)  Line of Credit:

     On behalf of the Fund and other funds in the Trust, and previously
     portfolios in the portfolio trust, the Trust has access to a credit
     facility, which enables each fund to borrow, in the aggregate, up to $35
     million under a committed line of credit and up to $15 million under an
     uncommitted line of credit. During the year ended September 30, 2007, the
     Fund did not have any loans outstanding.

(9)  Reorganization:

     Prior to September 19, 2007, the Fund had utilized a Master Feeder Fund
     structure where the Fund sought to achieve its investment objectives by
     investing all of its investable assets in the Boston Company Small Cap
     Value Portfolio. Effective after the close of business on September 19,
     2007, the Fund withdrew its assets from the Portfolio by means of a
     redemption-in-kind and now the Fund invests directly in portfolio
     securities.

     Below is the Statement of Operations for The Boston Company Small Cap Value
     Portfolio for the period October 1, 2006 to September 19, 2007:

                    The Boston Company Small Cap Value Fund

             Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------

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

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of The Boston Company Small Cap Value
Fund (the "Fund") at September 30, 2007, the results of its operations for the
year then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with accounting principles generally accepted
in the United States of America. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at September 30, 2007 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

MELLON INSTITUTIONAL FUNDS



September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.


While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

                   The Boston Company Small Cap Value Fund II


                       Management Discussion and Analysis
- --------------------------------------------------------------------------------

Small-cap stocks rallied early in the reporting period amid moderate economic
growth, stable short-term interest rates and rising corporate earnings. At the
time, investors maintained an ample appetite for risk, which benefited shares of
smaller companies more than their larger counterparts. However, the market
environment changed dramatically in mid-June 2007, when credit concerns in the
sub-prime mortgage sector spread to other areas of the financial markets. In the
ensuing market turbulence, newly risk-averse investors engaged in a "flight to
quality," and larger, higher-quality companies returned to favor.

The Federal Reserve Board attempted to improve market liquidity by reducing key
short-term interest rates in August and September. These moves bolstered
investor confidence that a recession could be avoided, sparking a market rally
late in the reporting period.

For the period July 20, 2007 to September 30, 2007, The Boston Company Small Cap
Value Fund II returned -4.40% as compared to the fund's benchmark, the Russell
2500 Value Index, which returned 1.04% over the same period. The fund
participated to a substantial degree in the small-cap market's advance. The fund
achieved particularly strong results among information technology companies,
including electron microscope semiconductors maker FEI Company, which gained
greater penetration of nanotechnology markets, and Microsemi Corp., which
continues to see strong growth in demand for its high performance analog chip. A
number of other semiconductor companies in the fund's portfolio also produced
strong returns during the reporting period. In the communications equipment
industry group, the fund scored successes with consumer networking equipment
manufacturer Netgear and telecommunications and military networking specialist
Comtech Telecommunications.

In the health care sector, home care services provider OptionCare was acquired
by pharmacy chain Walgreen, and medical helicopter services contractor Air
Methods captured a larger share of hospital and municipal markets. The energy
sector led the benchmark's performance during the reporting period, and the fund
participated in its strength through holdings such as oil well drilling
equipment maker Hydrill, which was acquired by energy services company Quanta
Services, and oil and gas operations specialty service provider CARBO Ceramics,
which boosted earnings after adding to manufacturing capacity. Among industrial
companies, engineering and construction firm Infrasource Services benefited from
increased investment in power transmission facilities, and Shaw Group gained
value in an improved global environment for the construction of nuclear power
plants as more nations develop alternatives to fossil fuels. Conversely, some
holdings and industry groups detracted from the fund's performance during the
reporting period. For example, regional electric utility PNM Resources was
unable to pass along higher commodity costs to its customers, and the fund's
underweighted position in the materials sector prevented it from participating
fully in the sector's strength as compared to the benchmark.

Although our "bottom-up" investment process does not consider macroeconomic
trends directly, we are aware that the U.S. economy is in the later stages of
its cycle and some market indices recently have set new record highs. In our
judgment, our relatively cautious, value-oriented approach to security selection
is well positioned for this environment, as it places a high degree of emphasis
on characteristics of individual companies such as solid business fundamentals,
healthy balance sheets and the ability to generate cash consistently. We
recently have found fewer opportunities meeting our criteria among industrial
companies, which have reached fuller valuations, and more in the information
technology, health care and consumer discretionary areas, which have offered
better values after extended periods of underperformance.

Aggregate total return reflects the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

                     Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period July 23, 2007 (commencement of operations)
to September 30, 2007.

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

ratio of 1.00%, multiplied by the average account value over the period,
multiplied by 70/365 (to reflect the number of days from commencement of

to the Fund's annualized expense ratio of 1.00%, multiplied by the average
account value over the period, multiplied by 183/365.

                   Mellon Institutional Funds Investment Trust
                   The Boston Company Small Cap Value Fund II


                          Notes to Financial Statements
- --------------------------------------------------------------------------------



(1)  Organization and 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 Value Fund II (the "Fund"), which commenced operation
     on July 23, 2007, 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. The Fu-nd focuses on companies with total market
     capitalizations within the range of companies included in the Russell 2500
     Value Index. The Fund intends to maintain an average weighted market
     capitalization that approximates that of the Russell 2500 Value Index.

     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

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. Securities are valued at the last sale prices on the exchange or
     national securities market on which they are primarily traded. Securities
     not listed on an exchange or national securities market, or securities for
     which there were no reported transactions, are valued at the last
     calculated mean price (average of last bid and last offer). Securities that
     are fixed income securities, other than short-term instruments with less
     than sixty days remaining to maturity, for which accurate market prices are
     readily available, are valued at their current market value on the basis of
     quotations, which may be furnished by a pricing service or dealers in such
     securities. Securities (including illiquid securities) for which quotations
     are not readily available, or if such quotations do not accurately reflect
     fair value, are valued at their fair value as determined in good faith
     under consistently applied procedures under the general supervision of the
     Trustees. With respect to any portion of the Fund's assets that are
     invested in one or more open-end regulated investment companies ("RICs"),
     the Fund's net asset value ("NAV") will be calculated based upon the NAVs
     of such RICs.

     Exchange traded options and futures are valued at the settlement price
     determined by the relevant exchange. Non-exchange traded derivatives are
     normally valued on the basis of quotes obtained from brokers and dealers,
     including counterparties or pricing services.

     Short-term instruments with less than sixty days remaining to maturity 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 cost based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized cost does not represent fair value.

     B. Securities transactions and income

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

     C. Distributions to shareholders

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from 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 reclassifications, are primarily due to losses deferred
     due to wash sales.

     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 (loss) and accumulated net
     realized gain (loss) on investments may include temporary book and tax
     basis differences which will be distributed in a subsequent period. Any
     taxable income or gain remaining at fiscal year end is distributed in the
     following year.

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


     D. Expenses

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

     E. Commitments and contingencies

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

     F. Affiliated issuers

     Affiliated issuers are investment companies advised by The Boston Company
     Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of The Bank of
     New York Mellon Corporation ("BNY Mellon"), or its affiliates.

     G. New accounting requirements

     On September 20, 2006, the Financial Accounting Standards Board ("FASB")
     released Statement of Financial Accounting Standards No. 157 "Fair Value
     Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition
     of fair value, sets out a framework for measuring fair value, and requires
     additional disclosures about fair-value measurements. The application of
     FAS 157 is required for fiscal years beginning after November 15, 2007 and
     interim periods within those fiscal years. At this time, management is
     evaluating the implications of FAS 157 and its impact, if any, in the
     financial statements has not yet been determined.

(2)  Investment Advisory Fee and Other Transactions With Affiliates:

     The investment advisory fee paid to TBCAM for overall investment advisory
     and administrative services, and general office facilities, is paid monthly
     at the annual rate of 0.75% of the Fund's average daily net assets. TBCAM
     voluntarily agreed to limit the Fund's total annual operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     1.00% of the Fund's average daily net assets for the period July 23, 2007
     (commencement of operations) to September 30, 2007. For the period July 23,
     2007 (commencement of operations) to September 30, 2007, TBCAM voluntarily
     waived its investment advisory fee in the amount of $7,841 and reimbursed
     the Fund for $53,288 of its operating expenses. This arrangement is
     voluntary and temporary and may be discontinued or revised by TBCAM at any
     time.

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a
     wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide personnel
     and facilities to perform transfer agency and certain shareholder services
     for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a
     fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $1,355, for the period July 23, 2007 (commencement of operations) to
     September 30, 2007. The Trust entered into an agreement with Mellon Bank,
     N.A. ("Mellon Bank"), a wholly-owned subsidiary of BNY Mellon and an
     affiliate of TBCAM, to provide custody, administration and accounting
     services for the Fund. For these services the Fund pays Mellon Bank a fixed
     fee plus asset and transaction based fees, as well as out-of-pocket
     expenses. Pursuant to this agreement, the Fund was charged $10,912 for the
     period July 23, 2007 (commencement of operations) to September 30, 2007.

     The Trust also entered into an agreement with Mellon Bank to perform
     certain securities lending activities and to act as the Fund's lending
     agent. Mellon Bank receives an agreed upon percentage of the net lending
     revenues. Pursuant to this agreement, the Fund was charged $303 for the
     period July 23, 2007 (commencement of operations) to September 30, 2007.
     See Note 6 for further details.

     The Trust entered into two separate agreements with The Bank of New York
     that enables the Fund, and other funds in the Trust, to borrow, in the
     aggregate, (i) up to $35 million from a committed line of credit and (ii)
     up to $15 million from an uncommitted line of credit. Interest is charged
     to each participating fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. The participating funds also
     pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
     uncommitted amounts and allocated ratably to the participating funds. In
     addition, a facility fee, computed at an annual rate of 0.060 of 1% on the
     committed amount, is allocated ratably among the participating funds at the
     end of each quarter. Pursuant to these agreements, the Fund was charged $20
     for the period July 23, 2007 (commencement of operations) to September 30,
     2007, which amount is included in miscellaneous expenses on the statement
     of operations. See Note 7 for further details.

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the period July 23,
     2007 (commencement of operations) to September 30, 2007, the Fund was
     charged $1,091, which amount is included in miscellaneous expenses in the
     statement of operations. No other 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 Fund pays each Trustee
     who is not a director, officer or employee of TBCAM or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out-of-pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of TBCAM, to provide printing and
     fulfillment services for the Fund. Pursuant to this agreement, the Fund was
     charged $97, which amount is included in miscellaneous expenses in the
     statement of operations, for the period July 23, 2007 (commencement of
     operations) to September 30, 2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     period July 23, 2007 (commencement of operations) to September 30, 2007,
     the Fund was not charged an administrative service fee by an affiliate of
     BNY Mellon.

     Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
     owned subsidiary of BNY Mellon and affiliate of TBCAM, replaced Mellon
     Funds Distributor, L.P. as the Fund's principal distributor. Effective July
     1, 2007, Mellon Financial Corporation ("MFC") and The Bank of New York
     Company, Inc. ("BNY") each merged into BNY Mellon, with BNY Mellon being
     the surviving entity of each merger.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term

     At September 30, 2007, three shareholders of record held in the aggregate
     94% of the total outstanding shares of the Fund. Investment activities of
     these shareholders could have a material impact on the Fund.

     The Fund imposes a redemption fee of 2% of the net asset value of the
     shares, with certain exceptions, which are redeemed or exchanged less than
     30 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that were acquired through reinvestment of
     distributions. For the period July 23, 2007 (commencement of operations) to
     September 30, 2007, the Fund did not assess any redemption fees.

                          Notes to Financial Statements
- -------------------------------------------------------------------------------


(5)  Federal Taxes:

     The Fund intends to qualify as a "regulated investment company" under
     Subchapter M of the Code. As such and by complying with the applicable
     provisions of the Code regarding the sources of its income, the timely
     distributions of its income to its shareholders, and the diversification of
     its assets, the Fund will not be subject to U.S. federal income tax on its
     investment company taxable income and net capital gain which are
     distributed to shareholders.

     In July 2006, FASB issued Interpretation No. 48, "Accounting for
     Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109"
     (the "Interpretation"). The Interpretation establishes for all entities,
     including pass-through entities such as the Fund, a minimum threshold for
     financial statement recognition of the benefit of positions taken in filing
     tax returns (including whether an entity is taxable in a particular
     jurisdiction), and requires certain expanded tax disclosures. Adoption of
     FIN 48 is required for fiscal years beginning after December 15, 2006 and
     is to be applied to all open tax years as of the effective date. At this
     time, management is evaluating the implication of FIN 48 and its impact on
     the financial statements has not yet been determined.

     The tax basis components of distributable earnings and the federal tax cost
     as of September 30, 2007 were as follows:

     The Fund elected to defer to its fiscal year ending September 30, 2008,
     $70,173 of capital losses recognized during the period July 23, 2007 to
     September 30, 2007.

(6)  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 for the period July 23, 2007
     (commencement of operations) to September 30, 2007 and earned interest on
     the invested collateral of $1,729 of which $1,020 was rebated to borrowers
     or paid in fees. At September 30, 2007, the Fund had securities valued at
     $263,508 on loan. See Schedule of Investments for further detail on the
     security positions on loan and collateral held.

(7)  Line of Credit:

     On behalf of the Fund, and other funds in the Trust, the Trust has access
     to a credit facility, which enables each fund to borrow, in the aggregate,
     up to $35 million under a committed line of credit and up to $15 million
     under an uncommitted line of credit.For the period July 23, 2007
     (commencement of operations) to September 30, 2007, the Fund had average
     borrowings outstanding of $4,000 for a total of one day and incurred $0 of
     interest expense. At September 30, 2007, the Fund did not have a loan
     balance outstanding.

                   The Boston Company Small Cap Value Fund II


             Report of Independent Registered Public Accounting Firm
- --------------------------------------------------------------------------------


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

     In our opinion, the accompanying statement of assets and liabilities,
     including the schedule of investments, and the related statements of
     operations and of changes in net assets and the financial highlights
     present fairly, in all material respects, the financial position of The
     Boston Company Small Cap Value Fund II (the "Fund") at September 30, 2007,
     and the results of its operations, the changes in its net assets and the
     financial highlights for the period from July 23, 2007 (commencement of
     operations) through September 30, 2007, 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 audit. We conducted our audit of these financial statements in
     accordance with the standards of the Public Company Accounting Oversight
     Board (United States). Those standards require that we plan and perform the
     audit to obtain reasonable assurance about whether the financial statements
     are free of material misstatement. An audit includes examining, on a test
     basis, evidence supporting the amounts and disclosures in the financial
     statements, assessing the accounting principles used and significant
     estimates made by management, and evaluating the overall financial
     statement presentation. We believe that our audit, which included
     confirmation of securities at September 30, 2007 by correspondence with the
     custodian and brokers, provides a reasonable basis for our opinion.

MELLON INSTITUTIONAL FUNDS

September 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
September 30, 2007.

The financial markets experienced a major bout of volatility in the summer
stemming from two principal sources: troubles in the credit markets related to
the difficulties experienced by mortgage securities backed by sub-prime loans,
and the high degree of leverage employed by many hedge funds, whose impact on
the markets has swollen significantly over the past decade. From its peak of
over 1550 in mid-July, the S&P 500 dropped by about 6.5%, before rebounding to
close the quarter at just under its peak for the 12-month period, resulting in
an 11.8% return over that period. Part of the rebound was due to the September
18 decision by the U.S. Federal Reserve Board to cut the Federal Funds rate by
50 basis points to 4.75%. This ended a string of nine consecutive meetings in
which the Fed left rates unchanged. The reduction was 25 basis points greater
than anticipated, driven by the Fed's concerns over the housing recession and
tighter credit availability.

Credit markets responded to the sub-prime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities. One result was a
significant steepening of the yield curve, as the yield on the 2-year Treasury
note fell 86 basis points to 3.98%, while the 30-year Treasury bond yield
dropped just 25 basis points to 4.84%. In a dramatic re-pricing of risk, spreads
widened in the corporate bond sector compared to Treasury issues, which has the
effect of making corporate borrowing more expensive. In another indication of
just how disruptive this period was in the credit markets, even some issuers of
commercial paper - typically viewed as the safest segment of the corporate
market - had trouble issuing or rolling over their issues.

While liquidity has slowly returned to the bond markets in general, the mortgage
sector clearly has been shaken, and this will likely exacerbate the housing
recession as financing becomes more expensive. In the view of some, the
likelihood of a broader U.S. recession has become greater. Our view is that a
period of diminished growth - around 2% GDP growth in 2008 vs. the 2.5%
long-term trend - is more likely. We see U.S. exports boosted by the weaker
dollar, multi-year global economic expansion and monetary growth, and high
corporate profitability - especially for multinational franchises - as being
positives that partially offset the drag of the housing sector and lower
consumption.

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,
Barbara McCann
President

                     Management Discussion and Analysis
- --------------------------------------------------------------------------------

For the year ended September 30, 2007, The Boston Company Emerging Markets Core
Equity Fund had a total return of 63.3% and outperformed its benchmark, the MSCI
Emerging Market Index, which returned 58.6%. During this period, emerging stocks
continued to post strong returns, outperforming their developed market peers.
Returns for the Index have been, in part, driven by China which surged over 130%
during the period. Peru (+132.3%), Brazil (+98.1%), Turkey (+86.3%), and Hungary
(+64.3%) rounded out the top five. Jordan was the only negatively performing
country in the Index and fell -8.8%. South Korea, the second largest weighted
country in the Index after China, (15.5%), returned a robust 45.7%.

The portfolio's positive return relative to its benchmark index was driven by
strong stock selection in South Korea, Russia and Malaysia. South Korean Hyundai
Heavy (+240.6%), Norilsk Nickel Mining of Russia (+118.5%), and Malaysian RHB
Capital (+133.6%) were the biggest contributors within those countries.
Conversely, we had weak stock selection in India as we trailed the benchmark's
return by 25.8%.

The Fund experienced positive stock selection in 9 of the 10 sectors. Materials
was the top performing sector as the Fund outpaced the Index return by 25.0% as
CVRD (+130.6) and Asia Cement (+168.7%) drove returns in this sector. Strong
stock selection in the Telecommunication Services and Consumer Staples sectors
also added 202 and 137 basis points respectively. On the other hand, we had weak
stock selection in the Health Care sector as the Fund's return of 21.6% trailed
the Index's return of 25.5%.

Emerging markets have had a remarkable run and given the projected growth of the
region, the outlook for the asset class is still positive. Financial volatility
ignited by the U.S. sub- prime mortgage fallout could extend further into the
end of this year. The extent to which tighter credit, rising loan delinquencies
and a chronically weak housing market hit overall U.S. consumption remains to be
seen. Although emerging markets remain financially sound and less dependant on
global demand than in previous economic cycles, a major decline in U.S. GDP
growth could hamper the robust expansion taking place in developing countries.
As always, we remain disciplined in our investment philosophy as we believe the
best opportunity is through stock selection. We will continue to use both
quantitative and fundamental techniques to buy stocks that we consider to
combine improving business momentum and attractive valuations.

Average annual total return reflects the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains. The
$100,000 line graph and the fund's returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. During periods of reimbursement by the fund's investment adviser (if
applicable), the fund's total return will be greater than it would be had the
reimbursement not occurred. Past performance is not predictive of future
performance.

              The Boston Company Emerging Markets Core Equity Fund

                     Shareholder Expense Example (Unaudited)
- --------------------------------------------------------------------------------

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

+ Expenses are equal to the Fund's annualized expense ratio of 1.45%,
  multiplied by the average account value over the period, multiplied by
  183/365 (to reflect the one-half year period).

                   Mellon Institutional Funds Investment Trust
              The Boston Company Emerging Markets Core Equity Fund


                          Notes to Financial Statements
- --------------------------------------------------------------------------------

(1)     Organization and 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 Emerging Markets Core Equity Fund (the
        "Fund"), which commenced operation on July 10, 2006, 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
        companies that are located in foreign countries represented in the
        Morgan Stanley Capital International Emerging Market (MSCI EM) Index.
        The Fund may also enter into equity index futures contracts based
        primarily on the indices of the countries included in the MSCI EM Index
        and Canada.

        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

        Fund shares are valued as of the close of regular trading (normally 4:00
        p.m., Eastern Time) on each day that the New York Stock Exchange
        ("NYSE") is open. Securities are valued at the last sale prices on the
        exchange or national securities market on which they are primarily
        traded. Securities not listed on an exchange or national securities
        market, or securities for which there were no reported transactions, are
        valued at the last calculated mean price (average of last bid and last
        offer). Securities that are fixed income securities, other than
        short-term instruments with less than sixty days remaining to maturity,
        for which accurate market prices are readily available, are valued at
        their current market value on the basis of quotations, which may be
        furnished by a pricing service or dealers in such securities. Securities
        (including illiquid securities) for which quotations are not readily
        available, or if such quotations do not accurately reflect fair value,
        are valued at their fair value as determined in good faith under
        consistently applied procedures under the general supervision of the
        Trustees. With respect to any portion of the Fund's assets that are
        invested in one or more open-end regulated investment companies
        ("RICs"), the Fund's net asset value ("NAV") will be calculated based
        upon the NAVs of such RICs.

        Exchange traded options and futures are valued at the settlement price
        determined by the relevant exchange. Non-exchange traded derivatives are
        normally valued on the basis of quotes obtained from brokers and
        dealers, including counterparties or pricing services.

        Because foreign markets may be open at different times than the NYSE,
        the value of the Fund's shares may change on days when shareholders are
        not able to buy or sell them. Many securities markets and exchanges
        outside the U.S. close prior to the close of the NYSE and therefore the
        closing prices for securities in such markets or on such exchanges may
        not fully reflect the events that occur after such close but before the
        close of the NYSE.

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

        Short-term instruments with less than sixty days remaining to maturity
        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
        cost based upon the value on such date unless the Trustees determine
        during such sixty-day period that amortized cost does not represent fair
        value.

        B. Securities transactions and income

        Securities transactions are recorded as of trade date. Interest income
        is determined on the basis of coupon interest accrued, adjusted for
        accretion of discount or amortization of premium using the
        yield-to-maturity method on debt securities with greater than sixty days
        remaining to maturity. 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.

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

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

        C. Distributions to shareholders

        Distributions to shareholders are recorded on the ex-dividend date. The
        Fund's distributions from 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 reclassifications, are primarily due to differing
        treatments for foreign currency transactions and losses deferred due to
        wash sales and post-October 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 (loss) and accumulated
        net realized gain (loss) on investments may include temporary book and
        tax basis differences which will be distributed in a subsequent period.
        Any taxable income or gain remaining at fiscal year end is distributed
        in the following year.

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

        D. Expenses

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

        E. Foreign currency transactions

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

        F. Foreign investment risk

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

        G. Commitments and contingencies

        In the normal course of business, the 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.

        H. Affiliated issuers

        Affiliated issuers are investment companies advised by The Boston
        Company Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of The
        Bank of New York Mellon Corporation ("BNY Mellon"), or its affiliates.

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

        I. New accounting requirements
        On September 20, 2006, the Financial Accounting Standards Board ("FASB")
        released Statement of Financial Accounting Standards No. 157 "Fair Value
        Measurements" ("FAS 157"). FAS 157 establishes an authoritative
        definition of fair value, sets out a framework for measuring fair value,
        and requires additional disclosures about fair-value measurements. The
        application of FAS 157 is required for fiscal years beginning after
        November 15, 2007 and interim periods within those fiscal years. At this
        time, management is evaluating the implications of FAS 157 and its
        impact, if any, in the financial statements has not yet been determined.

(2)     Investment Advisory Fee and Other Transactions With Affiliates:
        The investment advisory fee paid to TBCAM for overall investment
        advisory and administrative services, and general office facilities, is
        paid monthly at the annual rate of 1.10% of the Fund's average daily net
        assets. TBCAM voluntarily agreed to limit the Fund's total annual
        operating expenses (excluding brokerage commissions, taxes and
        extraordinary expenses) to 1.45% of the Fund's average daily net assets
        for the year ended September 30, 2007. Pursuant to this agreement, for
        the year ended September 30, 2007, TBCAM voluntarily waived a portion of
        its investment advisory fee in the amount of $99,997 and reimbursed the
        Fund for $58,342 of its operating expenses. This arrangement is
        voluntary and temporary and may be discontinued or revised by TBCAM at
        any time.

        The Trust entered into an agreement with Dreyfus Transfer, Inc., a
        wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned
        subsidiary of BNY Mellon and an affiliate of TBCAM, to provide personnel
        and facilities to perform transfer agency and certain shareholder
        services for the Fund. For these services the Fund pays Dreyfus
        Transfer, Inc. a fixed fee plus per account and transaction based fees,
        as well as, out-of-pocket expenses. Pursuant to this agreement, the Fund
        was charged $6,033, for the year ended September 30, 2007.

        The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon
        Bank"), a wholly-owned subsidiary of BNY Mellon and an affiliate of
        TBCAM, to provide custody, administration and accounting services for
        the Fund. For these services the Fund pays Mellon Bank a fixed fee plus
        asset and transaction based fees, as well as out-of-pocket expenses.
        Pursuant to this agreement, the Fund was charged $96,525 for the year
        ended September 30, 2007.

        The Trust also entered into an agreement with Mellon Bank to perform
        certain securities lending activities and to act as the Fund's lending
        agent. Mellon Bank receives an agreed upon percentage of the net lending
        revenues. Pursuant to this agreement, Mellon Bank earned $2,254 for the
        year ended September 30, 2007. See Note 7 for further details.

        The Trust entered into two separate agreements with The Bank of New York
        that enables the Fund, and other funds in the Trust, to borrow, in the
        aggregate, (i) up to $35 million from a committed line of credit and
        (ii) up to $15 million from an uncommitted line of credit. Interest is
        charged to each participating fund based on its borrowings at a rate
        equal to the Federal Funds effective rate plus 1/2 of 1%. The
        participating funds also pay an annual fee, computed at a rate of 0.020
        of 1% of the committed and uncommitted amounts and allocated ratably to
        the participating funds. In addition, a facility fee, computed at an
        annual rate of 0.060 of 1% on the committed amount, is allocated ratably
        among the participating funds at the end of each quarter. Pursuant to
        these agreements, the Fund was charged $142 for the year ended September
        30, 2007, which amount is included in miscellaneous expenses on the
        statement of operations. See Note 8 for further details.

        The Trust reimburses BNY Mellon Asset Management for a portion of the
        salary of the Trust's Chief Compliance Officer. For the year ended
        September 30, 2007, the Fund was charged $4,235, which amount is
        included in miscellaneous expenses in the statement of operations. No
        other 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 Fund pays each Trustee who is not a director,
        officer or employee of TBCAM or its affiliates an annual fee and a per
        meeting fee as well as reimbursement for travel and out-of-pocket
        expenses. In addition, the Trust pays the legal fees for the independent
        counsel of the Trustees.

        The Trust has contracted Mellon Investor Services LLC, a wholly owned
        subsidiary of BNY Mellon and an affiliate of TBCAM, to provide printing
        and fulfillment services for the Fund. Pursuant to this agreement, the
        Fund was charged $1,275, which amount is included in miscellaneous
        expenses in the statement of operations, for the year ended September
        30, 2007.

        The Fund may pay administrative service fees. These fees are paid to
        affiliated or unaffiliated retirement plans, omnibus accounts and
        platform administrators and other entities ("Plan Administrators") that
        provide record keeping and/or other administrative support services to
        accounts, retirement plans and their participants. As compensation for
        such services, the Fund may pay each Plan Administrator an
        administrative service fee in an amount of up to 0.15% (on an annualized
        basis) of the Fund's average daily net assets attributable to Fund
        shares that are held in accounts serviced by such Plan Administrator.
        The Fund's adviser or its affiliates may pay additional compensation
        from their own resources to Plan Administrators and other entities for
        administrative services, as well as in consideration of marketing or
        other distribution-related services. These payments may provide an
        incentive for these entities to actively promote the Fund or cooperate
        with the distributor's promotional efforts. For the year ended September
        30, 2007, the Fund was not charged an administrative service fee by an
        affiliate of BNY Mellon.

        Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly
        owned subsidiary of BNY Mellon and affiliate of TBCAM, replaced Mellon
        Funds Distributor, L.P. as the Fund's principal distributor.

        Effective July 1, 2007, Mellon Financial Corporation ("MFC") and The
        Bank of New York Company, Inc. ("BNY") each merged into BNY Mellon, with
        BNY Mellon being the surviving entity of each merger.

(4)     Shares of Beneficial Interest:

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

        At September 30, 2007, two shareholders of record, in the aggregate held
        approximately 72.5% of the total outstanding shares of the Fund.
        Investment activities of these shareholders could have a material impact
        on the Fund.

        The Fund imposes a redemption fee of 2% of the net asset value of the
        shares, with certain exceptions, which are redeemed or exchanged less
        than 30 days from the day of their purchase. The redemption fee is paid
        directly to the Fund, and is designed to offset brokerage commissions,
        market impact, and other costs associated with short-term trading in the
        Fund. The fee does not apply to shares that were acquired through
        reinvestment of distributions. For the year ended September 30, 2007,
        the Fund did not assess any redemption fees.

(5)     Federal Taxes:

        Each year, the Fund intends to qualify as a "regulated investment
        company" under Subchapter M of the Code. As such and by complying with
        the applicable provisions of the Code regarding the sources of its
        income, the timely distributions of its income to its shareholders, and
        the diversification of its assets, the Fund will not be subject to U.S.
        federal income tax on its investment company taxable income and net
        capital gain which are distributed to shareholders.

        In July 2006, FASB issued Interpretation No. 48, "Accounting for
        Uncertainty in Income Taxes - an Interpretation of FASB Statement No.
        109" (the "Interpretation"). The Interpretation establishes for all
        entities, including pass-through entities such as the Fund, a minimum
        threshold for financial statement recognition of the benefit of
        positions taken in filing tax returns (including whether an entity is
        taxable in a particular jurisdiction), and requires certain expanded tax
        disclosures. Adoption of FIN 48 is required for fiscal years beginning
        after December 15, 2006 and is to be applied to all open tax years as of
        the effective date. At this time, management is evaluating the
        implication of FIN 48 and its impact in the financial statements has not
        yet been determined.

        The tax basis components of distributable earnings and the federal tax
        cost as of September 30, 2007 were as follows:

(6)     Financial Instruments:

        In general, the following instruments are used for hedging purposes as
        described below. However, these instruments may also be used to seek to
        enhance potential gain in circumstances where hedging is not involved.

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

        Forward Foreign Currency Exchange Contracts

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

        At September 30, 2007, the Fund held forward foreign currency exchange
        contracts. See Schedule of Investments for further details.

(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

                                       19

                          Notes to Financial Statements
- --------------------------------------------------------------------------------

        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, 2007 and
        earned interest on the invested collateral of $12,348 of which $7,014
        was rebated to borrowers or paid in fees. At September 30, 2007, the
        Fund had securities valued at $277,977 on loan, of which $271,348 was
        collateralized with cash and $15,092 was collateralized with highly
        liquid securities. See Schedule of Investments for further detail on the
        security positions on loan and collateral held.

(8)     Line of Credit:

        On behalf of the Fund and other funds in the Trust, the Trust has access
        to a credit facility, which enables each fund to borrow, in the
        aggregate, up to $35 million under a committed line of credit and up to
        $15 million under an uncommitted line of credit.For the year ended
        September 30, 2007, the Fund had average borrowings outstanding of
        $47,750 for a total of four days and incurred $31 of interest expense.
        At September 30, 2007, the Fund did not have a loan balance outstanding.

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

        In our opinion, the accompanying statement of assets and liabilities,
        including the schedule of investments, and the related statements of
        operations and of changes in net assets and the financial highlights
        present fairly, in all material respects, the financial position of The
        Boston Company Emerging Markets Core Equity Fund (the "Fund") at
        September 30, 2007, the results of its operations for the year then
        ended, and the changes in its net assets and the financial highlights
        for the year then ended and for the period from July 10, 2006
        (commencement of operations) to September 30, 2006, in conformity with
        accounting principles generally accepted in the United States of
        America. These financial statements and financial highlights (hereafter
        referred to as "financial statements") are the responsibility of the
        Fund's management. Our responsibility is to express an opinion on these
        financial statements based on our audits. We conducted our audits of
        these financial statements in accordance with the standards of the
        Public Company Accounting Oversight Board (United States). Those
        standards require that we plan and perform the audit to obtain
        reasonable assurance about whether the financial statements are free of
        material misstatement. An audit includes examining, on a test basis,
        evidence supporting the amounts and disclosures in the financial
        statements, assessing the accounting principles used and significant
        estimates made by management, and evaluating the overall financial
        statement presentation. We believe that our audits, which included
        confirmation of securities at September 30, 2007 by correspondence with
        the custodian and brokers, provide a reasonable basis for our opinion.
