                        Newton International 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 (October 1, 2007 to March 31, 2008).

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 transactional costs, such as sales
charges (loads), redemption fees, or exchange fees. Therefore, the second line
of the table is useful in comparing ongoing costs only, 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.

     redesignated as Class I shares. Class A, Class C and R shares are sold
     primarily to retail investors through financial intermediaries and bear a
     distribution fee and/or shareholder services fee. Class A shares are sold
     with a front-end sales charge, while Class C shares are subject to a
     contingent deferred sales charge ("CDSC"). Class I shares are sold
     primarily to bank trust departments and other financial service providers
     (including Mellon Bank, N.A. and its affiliates) acting on behalf of
     customers having a qualified trust or an investment account or relationship
     at such institution or to qualified institutional investors who are
     advisory clients of the fund's investment adviser, and bear no distribution
     or shareholder services fees. Class I shares are offered without a
     front-end sales charge or CDSC. Each class of shares has identical rights
     and privileges, except with respect to distribution and service fees and
     voting rights on matters affecting a single class. Income, expenses (other
     than expenses attributable to a specific class), and realized and
     unrealized gains or losses on investments are allocated to each class of
     shares based on its relative net assets.

     As of March 31, 2008, MBC Investments Corp., a wholly-owned subsidiary of
     The Bank of New York Mellon Corporation and an affiliate of the Fund's
     investment adviser, held all of the outstanding Class A, Class C, and Class
     R shares of the fund.

     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.

     Effective March 5, 2008, Jon Bell replaced Paul Butler as a co-portfolio
     manager of the Fund.

     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.

                                       16



                   Mellon Institutional Funds Investment Trust
                        Newton International Equity Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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 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 (the "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. Investment income, common expenses and realized and unrealized
     gains and losses are allocated among the share classes of the Fund based on
     the relative net assets of each class. Transfer agent fees, which are
     directly attributable to a class of shares, are charged to that share
     class. Rule 12b-1 fees, which are directly attributable to Class C and R
     shares, and shareholder service fees, which are directly attributable to
     Class A, C and R shares, are charged to Class A, C and R shares, as
     appropriate.

     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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161 "Disclosures about Derivative Instruments and Hedging
     Activities" ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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 payable
     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
     for Class A, C, I and R shares, and also excluding Rule 12b-1 fees,
     shareholder services fees for Class A and C shares) to 1.15% of the average
     daily net assets of Class A, C, I and R shares. Pursuant to this agreement,
     for the six months ended March 31, 2008, Newton voluntarily waived a
     portion of its investment advisory fee in the amount of $101,052, and for
     March 31, 2008 (commencement of operations), reimbursed Class A, C and R
     shares for class specific and fund operating fees in the amounts of $16,
     $16, $16, respectively. This arrangement is voluntary and temporary and may
     be discontinued or revised by Newton at any time.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of Newton, is the distributor of the Fund's shares.
     Under the Distribution Plan (the "Plan") adopted pursuant to Rule 12b-1
     under the Act, Class C and Class R shares pay MBSC for distributing their
     shares at an annual rate of 0.75% of the value of the average daily net
     assets of Class C shares and 0.25% of the value of the average daily net
     assets of Class R shares. During the period ended March 31, 2008, Class C
     and Class R shares were charged $0.20 and $0.07, respectively, pursuant to
     the Plan.

     Under the Shareholder Services Plan, Class A, Class C and Class R shares
     pay MBSC at an annual rate of 0.25% of the value of their average daily net
     assets for the provision of certain services. The services provided may
     include personal services relating to shareholder accounts, such as

                                       18



                   Mellon Institutional Funds Investment Trust

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     answering shareholder inquiries regarding the Fund and providing reports
     and other information, and services related to the maintenance of
     shareholder accounts. MBSC may make payments to Service Agents (a
     securities dealer, financial institution or other industry professional) in
     respect of these services. MBSC determines the amounts to be paid to
     Service Agents. During the period ended March 31, 2008, Class A, Class C
     and Class R shares were charged $ 0.07, $0.07 and $0.07, respectively,
     pursuant to the Shareholder Services Plan. Under its terms, the Plan and
     Shareholder Services Plan shall remain in effect from year to year,
     provided such continuance is approved annually by a vote of majority of
     those Trustees who are not "interested persons" of the Trust and who have
     no direct or indirect financial interest in the operation of or in any
     agreement related to the Plan or Shareholder Services Plan.

     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
     $2,814 for Class I shares, for the six months ended March 31, 2008, and the
     amounts of $16, $16, $16, for Class A, C and R shares, respectively, for
     March 31, 2008 (commencement of operations).

     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 fund accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $92,584 for the six months ended March 31,
     2008.

     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
     $862 for the six months ended March 31, 2008, which amount is included in
     miscellaneous expenses in 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 six months ended
     March 31, 2008, the Fund was charged $2,830, 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 $740, which amount is included in miscellaneous expenses in the
     statement of operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was not charged an administrative
     service fee by an affiliate of BNY Mellon.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the six months ended March 31, 2008 were as follows:

(4)  Shares of Beneficial Interest:

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

                  Mellon Institutional Funds Investment Trust
                        Newton International Equity Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     At March 31, 2008, four shareholders of record (including MBC Investments
     Corp., a wholly-owned subsidiary of BNY Mellon and an affiliate of Newton),
     in the aggregate held approximately 100%, 100%, 87.6% and 100% of the total
     outstanding shares of the Fund's Class A, C, I and R shares, respectively.
     Investment activities of these shareholders could have a material impact on
     the Fund. For example, a significant redemption by such shareholders could
     result in illiquid or less liquid investments comprising a large portion of
     the Fund's portfolio.

     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 (for Class I shares) or 60 days (for Class A, C and R shares) from
     the day of their purchase. The redemption fee is paid directly to the
     applicable share class of 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 six months ended March 31,
     2008, 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, were as follows:


                                                        
                  Cost for federal income tax purposes     $ 45,489,172
                                                           ------------
                  Gross unrealized appreciation            $  4,948,102
                  Gross unrealized depreciation              (2,655,427)
                                                           ------------
                  Net unrealized appreciation
                    (depreciation)                         $  2,292,675
                                                           ============


(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:

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

                                       21




                  Mellon Institutional Funds Investment Trust
                        Newton International Equity Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

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

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

     At March 31, 2008, the Fund held purchased options. See the Schedule of
     Investments for further details.

     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 March 31, 2008, the Fund held forward foreign currency exchange
     contracts. See the Schedule of Investments for further details.

(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 six months ended March 31, 2008, the
     Fund had average borrowings outstanding of $318,667 for a total of 27 days
     and incurred interest expense of $1,189. At March 31, 2008, the Fund did
     not have a loan balance outstanding.

                   Mellon Institutional Funds Investment Trust
                        Newton International Equity Fund

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. In their
     most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from the Fund's investment adviser, Newton
     Capital Management Ltd. ("Newton" or the "Adviser"), a broad range of
     information in response to a written request prepared on their behalf by
     their own legal counsel. The Independent Trustees met alone in a private
     session with their legal counsel on September 27, 2007 to review these
     materials and to discuss the proposed continuation of the Fund's advisory
     agreement. Representatives of management attended a portion of the
     September meeting to provide an overview of the Adviser's organization,
     personnel, resources and strategic plans, and to respond to questions and
     comments arising from the Independent Trustees' review of the materials and
     their deliberations. The entire Board then met on October 30, 2007.

     The information requested by the Independent Trustees and reviewed by the
     entire Board included:

     (i) Financial and Economic Data: The Adviser's balance sheet and income
     statements, as well as a profitability analysis of the Adviser, including a
     separate presentation of the Adviser's profitability relative to that of
     several publicly traded investment advisers;

     (ii) Management Teams and Operations: The Adviser's Form ADV, as well as
     information concerning the Adviser's executive management, portfolio
     management, client service personnel and overall organizational structure,
     insurance coverage, brokerage and soft dollar policies and practices;

     (iii) Comparative Performance and Fees: Analyses prepared by Lipper
     Analytical Services ("Lipper") regarding the Fund's historical performance,
     management fee and expense ratio compared to other funds, and the Adviser's
     separate account advisory fee schedules;

     (iv) Specific Facts Relating to the Fund: The Adviser's commentary on the
     Fund's performance and any material portfolio manager and strategy changes
     that may have affected the Fund in the prior year, as well as the Fund's
     "fact sheets" prepared by the Adviser providing salient data about the
     Fund, including the Fund's holdings, strategies, recent market conditions
     and outlook, as well as the Adviser's views concerning the issues of
     breakpoints in the management fee schedule of the Fund and potential
     economies of scale; and

     (v) Other Benefits: The benefits flowing to The Bank of New York Mellon
     Corporation ("BNY Mellon") and its affiliates in the form of fees for
     transfer agency, custody, administration and securities lending services
     provided to the Funds by affiliates of BNY Mellon.

     In considering the continuation of the Fund's advisory agreement, the Board
     of Trustees, including the Independent Trustees, did not identify any
     single factor as all-important or controlling, and individual Trustees did
     not necessarily attribute the same weight or importance to each factor. The
     Trustees determined that the terms and conditions of the advisory agreement
     and the compensation to the Adviser provided therein were fair and
     reasonable in light of the services performed, expenses incurred and such
     other matters as the Trustees considered relevant in the exercise of their
     reasonable judgment. The following summary does not detail all the matters
     that were considered. Some of the factors that figured prominently in the
     Trustees' determination are described below.

     Nature, Extent and Quality of Services
     The Board considered the nature, scope and quality of the overall services
     provided to the Fund by the Adviser. In their deliberations as to the
     continuation of the advisory agreement, the Trustees were also mindful of
     the fact that, by choosing to invest in the Fund, the Fund's shareholders
     have chosen to entrust the Adviser, under the supervision of the Board, to
     manage the portion of their assets invested in the Fund.

     Among the specific factors the Board reviewed were the investment
     management, administrative, compliance and related services provided by the
     Adviser. The Board determined that the services provided were of high
     quality and at least commensurate with industry standards.

     The Trustees reviewed the background and experience of the Fund's two
     portfolio managers and also met with senior management of the Adviser to
     receive an overview of its organization, personnel, resources and strategic
     plans. Among other things, the Trustees considered the size, education and
     experience of the Adviser's investment staff, technological infrastructure
     and overall responsiveness to changes in market conditions.

     The Board determined that the Adviser had the expertise and resources to
     manage the Fund effectively.

     Investment Performance
     The Board considered the investment performance of the Fund against a peer
     group of investment companies selected by the Adviser with input from the
     Trustees. The Board also compared the Fund's investment performance against
     the average performance of a larger universe of funds regarded by Lipper as
     having similar investment objectives and considered the Fund's performance
     rankings against that universe. In addition to the information received by
     the Board at the September 27, 2007 Board meeting, the Trustees received
     similar detailed comparative performance information for the Fund at each
     regular Board meeting during the year.

     The Board considered the Fund's performance for the one-year period ended
     July 31, 2007 based on the Lipper materials provided to the Board at the
     September 27, 2007 meeting. The Board found that the Fund underperformed
     its peer group average return for the one-year period (20.14% vs. 22.99%).
     The Board noted that the Fund recently commenced operations and had a very
     short performance history and that the other funds in its peer group were
     substantially larger than the Fund.

                   Mellon Institutional Funds Investment Trust
                        Newton International Equity Fund

              Factors Considered by the Trustees in Approving the
                    Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Advisory Fee and Other Expenses
     The Board considered the advisory fee rate paid by the Fund to the Adviser.
     The Lipper data presenting the Fund's "net management fees" included fees
     paid by the Fund, as calculated by Lipper, for administrative services
     provided by Mellon Bank, N.A., the Trust's custodian. Such reporting was
     necessary, according to Lipper, to allow the Board to compare the Fund's
     advisory fees to those peers that include administrative fees within a
     blended advisory fee.

     The Fund's contractual advisory fee was 0.80%, which was in the 3rd (1st
     being the best) quintile of its peer group of funds, the median fee of
     which was 0.80%. The Fund's net management fee (after giving effect to
     expense limitations) was 0.47% (which included administrative services fees
     under Lipper's calculation methodology), well below the peer group median
     net management fee of 0.777%. Based on the Lipper data, as well as other
     factors discussed at the September 27, 2007 meeting, the Board determined
     that the Fund's advisory fee is reasonable relative to its peer group
     averages.

     The Board also compared the fees payable by the Fund relative to those
     payable by separate account clients of the Adviser. Based on the additional
     scope and complexity of the services provided and responsibilities assumed
     by the Adviser with respect to the Fund relative to these other types of
     clients, the Board concluded that the fees payable under the advisory
     agreement were reasonable relative to the nature and quality of the
     services provided.

     The Board also considered the Fund's expense ratio and compared it to that
     of its peer group of similar funds. The Board found that the actual net
     expense ratio of 1.15% (after giving effect to expense limitations) was
     higher than the median net expense ratio of the peer group of 0.94%,
     largely due to the Fund's small asset size compared to its peer group.

     The Adviser's Profitability
     The Board considered the Adviser's profitability in managing the Fund and
     the Mellon Institutional Funds as a group, as well as the methodology used
     to compute such profitability, and the various direct and indirect expenses
     incurred by the Adviser or its affiliated investment advisers in managing
     the Fund and other funds in the Mellon Institutional Funds family of funds.
     The Independent Trustees had observed that the Adviser, based on the
     profitability information submitted to them by the Adviser, incurred losses
     in managing many of the investment companies in the Mellon Institutional
     Funds family of funds. The Trustees observed that the Adviser had incurred
     a gain in operating the Fund in 2006.

     Economies of Scale
     The Board also considered the extent to which economies of scale might be
     realized as the Fund grows. They observed that the Standish Mellon Fixed
     Income Fund and The Boston Company International Core Equity Fund, two of
     the largest funds in the complex, already had breakpoints in their fee
     arrangements that reflected economies resulting from their size. The Board
     also noted that at the March 7, 2006 meeting, management had presented a
     Breakpoint Discussion Memorandum that had proposed a framework for future
     breakpoints. The Board concluded that, at existing asset levels and
     considering current asset growth projections, the implementation of
     additional fee breakpoints or other fee reductions was not necessary at
     this time.

     Other Benefits
     The Board also considered the additional benefits flowing to BNY Mellon as
     a result of its relationship with the Mellon Institutional Funds as a
     group, including revenues received by BNY Mellon affiliates in
     consideration of custodial, administrative, transfer agency and securities
     lending services provided by such affiliates to the Funds. In each case,
     such affiliates were selected by the Board on the basis of a comparative
     analysis of their capabilities and fees relative to those of unaffiliated
     competitors.

     The Board considered the fact that BNY Mellon operates businesses other
     than the Mellon Institutional Funds, some of which businesses share
     personnel, office space and other resources and that these were a component
     of the profitability analysis provided. The Board also considered the
     intangible benefits that accrue to BNY Mellon and its affiliates by virtue
     of its relationship with the Funds and the Mellon Institutional Funds as a
     group.

                                      * * *

     The foregoing factors were among those weighed by the Trustees in
     determining that the terms and conditions of the Fund's advisory agreement
     and the compensation to the Adviser provided therein are fair and
     reasonable and, thus, in approving the continuation of the agreement for a
     one-year period.

March 31, 2008 (Unaudited)

general information of the shareholders of the Fund. This report is not
authorized for distribution to prospective investors in the Fund unless preceded

Any information in this shareholder report regarding market or economic trends

                   Mellon Institutional Funds Investment Trust
                      Mellon Capital Large Cap Growth 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 (October 1, 2007 to March 31, 2008).

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
   183/366 (to reflect the one-half year period).

                      Mellon Capital Large Cap Growth Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------


(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 Capital Large Cap Growth Fund (the "Fund"), which commenced
     operation on December 21, 2005, is a separate diversified investment series
     of the Trust.

     Through December 31, 2007, Mellon Equity Associates LLP ("Mellon Equity")
     had served as the investment adviser to the Fund. Effective on that date,
     Mellon Equity and Mellon Capital Management Corporation ("Mellon Capital"),
     each a wholly-owned subsidiary of The Bank of New York Mellon Corporation
     ("BNY Mellon"), merged into one surviving investment adviser, Mellon
     Capital. After the merger, Mellon Capital remains an indirect wholly-owned
     subsidiary of BNY Mellon. Effective January 1, 2008, Mellon Capital
     replaced Mellon Equity as the investment adviser to the Fund and the Fund
     changed its name from "Mellon Equity Large Cap Growth Fund." There have
     been no changes to the terms of the investment advisory agreement or to the
     portfolio manager line-up of the Fund.

     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 registered 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.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------


     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 Capital, a
     wholly-owned subsidiary of BNY Mellon, or its affiliates.

     G. 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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes has
     not yet been determined.

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

     The investment advisory fee paid to Mellon Capital 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 Capital 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 six months ended March 31, 2008. Pursuant to this agreement, for the
     six months ended March 31, 2008, Mellon Capital voluntarily waived its
     investment advisory fee in the amount of $9,617 and reimbursed $51,152 of
     the Fund's operating expenses. This arrangement is voluntary and temporary
     and may be discontinued or revised by Mellon Capital 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 Capital, to provide
     personnel and facilities to perform transfer agency and certain shareholder
     services for the Fund. For these services the Fund pays Dreyfus Transfer,
     Inc. a fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $3,065, for the six months ended March 31, 2008.

     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 Capital,
     to provide custody, administration and fund accounting services for the
     Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset
     and transaction based fees, as well as out-of-pocket expenses. Pursuant to
     this agreement, the Fund was charged $22,229 for the six months ended March
     31, 2008.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------


     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 $240 for the six
     months ended March 31, 2008. 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 $40
     for the six months ended March 31, 2008, 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 six months ended
     March 31, 2008, the Fund was charged $2,130, which amount is included in
     miscellaneous expenses in the statement of operations. No other director,
     officer or employee of Mellon Capital 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 Capital 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
     six months ended March 31, 2008, 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 Capital, to provide
     printing and fulfillment services for the Fund. Pursuant to this agreement,
     the Fund was charged $1,500, which amount is included in miscellaneous
     expenses in the statement of operations, for the six months ended March 31,
     2008.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of Mellon Capital, is the distributor of the Fund's
     shares.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the six months ended March 31, 2008 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

                   Mellon Institutional Funds Investment Trust
                      Mellon Capital Large Cap Growth Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------


     At March 31, 2008, one shareholder of record, (MBC Investment Corp., a
     wholly owned subsidiary of BNY Mellon and an affiliate of Mellon Capital)
     in the aggregate held approximately 96% of the total outstanding shares of
     the Fund. Investment activities of these shareholders could have a material
     impact on the Fund. For example, a significant redemption by such
     shareholders could result in illiquid or less liquid investments comprising
     a larger portion of the Fund's Portfolio.

     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 six months ended March 31, 2008, the Fund did not
     assess any redemption fees.

(5)  Federal Taxes:

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, were as follows:


                                                         
              Cost for federal income tax purposes          $2,823,485
                                                            ==========
              Gross unrealized appreciation                 $  271,115
              Gross unrealized depreciation                   (233,501)
                                                            ----------
              Net unrealized appreciation (depreciation)    $   37,614
                                                            ==========


(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.

     Until December 10, 2007, all cash collateral received by the Fund and other
     series of the Trust in connection with the securities lending program was
     invested in the BlackRock Cash Strategies Fund LLC (the "BlackRock Fund"),
     a private investment fund not affiliated with the Trust or its investment
     adviser. On December 10, 2007, the BlackRock Fund announced that it was
     suspending investor withdrawal privileges due to conditions related to the
     credit markets and the adverse affect of such conditions on the liquidity
     of the BlackRock Fund's portfolio holdings. Commencing on December 11,
     2007, all new cash collateral received in connection with the securities
     lending activity of the Fund and other series of the Trust was invested by
     the securities lending agent in the Dreyfus Institutional Cash Advantage
     Fund (the "Dreyfus Fund"), an affiliated money market fund registered as an
     investment company under the Investment Company Act of 1940, as amended. To
     the extent that the BlackRock Fund agreed to permit withdrawals during the
     period December 11, 2007 through March 31, 2008, the security lending agent
     effected such withdrawals and the cash

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     proceeds from such withdrawals by the Fund were reinvested in shares of the
     Dreyfus Fund. Repayments of cash collateral during the period were made
     from the proceeds of redemptions of shares of the Dreyfus Fund. See
     Schedule of Investments for further detail on the Fund's investment of cash
     collateral in the BlackRock Fund and the Dreyfus Fund as of March 31, 2008.

     The Fund loaned securities during the six months ended March 31, 2008 and
     earned interest on the invested collateral of $1,622 of which $1,062 was
     rebated to borrowers or paid in fees. 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. During the six months ended March 31, 2008,
     the Fund had average borrowing outstanding of $3,600 for a total of ten
     days an incurred $6 of interest expense. At March 31, 2008, the Fund did
     not have an outstanding loan balance.

                   Mellon Institutional Funds Investment Trust
                      Mellon Capital Large Cap Growth Fund

              Factors Considered by the Trustees in Approving the
                    Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------


     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. In their
     most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from the Fund's investment adviser, Mellon
     Capital Corporation ("Mellon Capital" or the "Adviser"), a broad range of
     information in response to a written request prepared on their behalf by
     their own legal counsel. The Independent Trustees met alone in a private
     session with their legal counsel on September 27, 2007 to review these
     materials and to discuss the proposed continuation of the Fund's advisory
     agreement. Representatives of management attended a portion of the
     September meeting to provide an overview of the Adviser's organization,
     personnel, resources and strategic plans, and to respond to questions and
     comments arising from the Independent Trustees' review of the materials and
     their deliberations. The entire Board then met on October 30, 2007.

     The information requested by the Independent Trustees and reviewed by the
     entire Board included:

     (i) Financial and Economic Data: The Adviser's balance sheet and income
     statements, as well as a profitability analysis of the Adviser, including a
     separate presentation of the Adviser's profitability relative to that of
     several publicly traded investment advisers;

     (ii) Management Teams and Operations: The Adviser's Form ADV, as well as
     information concerning the Adviser's executive management, portfolio
     management, client service personnel and overall organizational structure,
     insurance coverage, brokerage and soft dollar policies and practices;

     (iii) Comparative Performance and Fees: Analyses prepared by Lipper
     Analytical Services ("Lipper") regarding the Fund's historical performance,
     management fee and expense ratio compared to other funds, and the Adviser's
     separate account advisory fee schedules;

     (iv) Specific Facts Relating to the Fund: The Adviser's commentary on the
     Fund's performance and any material portfolio manager and strategy changes
     that may have affected the Fund in the prior year, as well as the Fund's
     "fact sheets" prepared by the Adviser providing salient data about the
     Fund, including the Fund's holdings, strategies, recent market conditions
     and outlook, as well as the Adviser's views concerning the issues of
     breakpoints in the management fee schedule of the Fund and potential
     economies of scale; and

     (v) Other Benefits: The benefits flowing to The Bank of New York Mellon
     Corporation ("BNY Mellon") and its affiliates in the form of fees for
     transfer agency, custody, administration and securities lending services
     provided to the Funds by affiliates of BNY Mellon.

     In considering the continuation of the Fund's advisory agreement, the Board
     of Trustees, including the Independent Trustees, did not identify any
     single factor as all-important or controlling, and individual Trustees did
     not necessarily attribute the same weight or importance to each factor. The
     Trustees determined that the terms and conditions of the advisory agreement
     and the compensation to the Adviser provided therein were fair and
     reasonable in light of the services performed, expenses incurred and such
     other matters as the Trustees considered relevant in the exercise of their
     reasonable judgment. The following summary does not detail all the matters
     that were considered. Some of the factors that figured prominently in the
     Trustees' determination are described below.

     Nature, Extent and Quality of Services

     The Board considered the nature, scope and quality of the overall services
     provided to the Fund by the Adviser. In their deliberations as to the
     continuation of the advisory agreement, the Trustees were also mindful of
     the fact that, by choosing to invest in the Fund, the Fund's shareholders
     have chosen to entrust the Adviser, under the supervision of the Board, to
     manage the portion of their assets invested in the Fund.

     Among the specific factors the Board reviewed were the investment
     management, administrative, compliance and related services provided by the
     Adviser. The Board determined that the services provided were of high
     quality and at least commensurate with industry standards.

     The Trustees reviewed the background and experience of the Fund's two
     portfolio managers and also met with senior management of the Adviser to
     receive an overview of its organization, personnel, resources and strategic
     plans. Among other things, the Trustees considered the size, education and
     experience of the Adviser's investment staff, technological infrastructure
     and overall responsiveness to changes in market conditions.

     The Board determined that the Adviser had the expertise and resources to
     manage the Fund effectively.

     Investment Performance

     The Board considered the investment performance of the Fund against a peer
     group of investment companies selected by the Adviser with input from the
     Trustees. The Board also compared the Fund's investment performance against
     the average performance of a larger universe of funds regarded by Lipper as
     having similar investment objectives and considered the Fund's performance
     rankings against that universe. In addition to the information received by
     the Board at the September 27, 2007 Board meeting, the Trustees received
     similar detailed comparative performance information for the Fund at each
     regular Board meeting during the year.

                   Mellon Institutional Funds Investment Trust
                      Mellon Capital Large Cap Growth Fund

              Factors Considered by the Trustees in Approving the
                    Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The Board considered the Fund's performance for the one-year period ended
     July 31, 2007 based on the Lipper materials provided to the Board at the
     September 27, 2007 meeting. The Board found that the Fund underperformed
     its peer group average return for the one-year period (18.09% vs. 18.46%).
     The Board noted that the Fund recently commenced operations and had a very
     short performance history and that the other funds in its peer group were
     substantially larger than the Fund.

     Advisory Fee and Other Expenses

     The Board considered the advisory fee rate paid by the Fund to the Adviser.
     The Lipper data presenting the Fund's "net management fees" included fees
     paid by the Fund, as calculated by Lipper, for administrative services
     provided by Mellon Bank, N.A., the Trust's custodian. Such reporting was
     necessary, according to Lipper, to allow the Board to compare the Fund's
     advisory fees to those peers that include administrative fees within a
     blended advisory fee.

     The Fund's contractual advisory fee was 0.65%, which was in the 2nd (1st
     being the best) quintile of its peer group of funds, the median fee of
     which was 0.695%. The Fund's entire management fee was reimbursed by the
     Adviser. By comparison, the peer group median net management fee was
     0.569%. Based on the Lipper data, as well as other factors discussed at the
     September 27, 2007 meeting, the Board determined that the Fund's advisory
     fee is reasonable relative to its peer group averages.

     The Board also compared the fees payable by the Fund relative to those
     payable by separate account clients of the Adviser. Based on the additional
     scope and complexity of the services provided and responsibilities assumed
     by the Adviser with respect to the Fund relative to these other types of
     clients, the Board concluded that the fees payable under the advisory
     agreement were reasonable relative to the nature and quality of the
     services provided.

     The Board also considered the Fund's expense ratio and compared it to that
     of its peer group of similar funds. The Board found that the actual net
     expense ratio of 0.95% (after giving effect to expense limitations) was
     higher than the median net expense ratio of the peer group of 0.767%,
     largely due to the Fund's small asset size compared to its peer group.

     The Adviser's Profitability

     The Board considered the Adviser's profitability in managing the Fund and
     the Mellon Institutional Funds as a group, as well as the methodology used
     to compute such profitability, and the various direct and indirect expenses
     incurred by the Adviser or its affiliated investment advisers in managing
     the Fund and other funds in the Mellon Institutional Funds family of funds.
     The Independent Trustees had observed that the Adviser, based on the
     profitability information submitted to them by the Adviser, incurred losses
     in managing many of the investment companies in the Mellon Institutional
     Funds family of funds. The Trustees observed that the Adviser had incurred
     a gain in operating the Fund in 2006.

     Economies of Scale

     The Board also considered the extent to which economies of scale might be
     realized as the Fund grows. They observed that the Standish Mellon Fixed
     Income Fund and The Boston Company International Core Equity Fund, two of
     the largest funds in the complex, already had breakpoints in their fee
     arrangements that reflected economies resulting from their size. The Board
     also noted that at the March 7, 2006 meeting, management had presented a
     Breakpoint Discussion Memorandum that had proposed a framework for future
     breakpoints. The Board concluded that, at existing asset levels and
     considering current asset growth projections, the implementation of
     additional fee breakpoints or other fee reductions was not necessary at
     this time.

     Other Benefits

     The Board also considered the additional benefits flowing to BNY Mellon as
     a result of its relationship with the Mellon Institutional Funds as a
     group, including revenues received by BNY Mellon affiliates in
     consideration of custodial, administrative, transfer agency and securities
     lending services provided by such affiliates to the Funds. In each case,
     such affiliates were selected by the Board on the basis of a comparative
     analysis of their capabilities and fees relative to those of unaffiliated
     competitors.

     The Board considered the fact that BNY Mellon operates businesses other
     than the Mellon Institutional Funds, some of which businesses share
     personnel, office space and other resources and that these were a component
     of the profitability analysis provided. The Board also considered the
     intangible benefits that accrue to BNY Mellon and its affiliates by virtue
     of its relationship with the Funds and the Mellon Institutional Funds as a
     group.

                                      * * *

     The foregoing factors were among those weighed by the Trustees in
     determining that the terms and conditions of the Fund's advisory agreement
     and the compensation to the Adviser provided therein are fair and
     reasonable and, thus, in approving the continuation of the agreement for a
     one-year period.

                   Mellon Institutional Funds Investment Trust
              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 (October 1, 2007 to March 31, 2008).

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 Emerging Markets Core Equity Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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"), 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 (the "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

     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.

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

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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 six months ended March
     31, 2008. Pursuant to this agreement, for the six months ended March 31,
     2008, TBCAM voluntarily waived a portion of its investment advisory fee in
     the amount of $71,456. 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
     $3,170, for the six months ended March 31, 2008.

     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 $46,346 for the six months ended March 31,
     2008.

     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 $1,030 for the six
     months ended March 31, 2008. 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 $49
     for the six months ended March 31, 2008, 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 six months ended
     March 31, 2008, the Fund was charged $2,130, 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 $775, which amount is included in miscellaneous expenses in the
     Statement of Operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was not charged an administrative
     service fee by an affiliate of BNY Mellon.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of TBCAM, is the distributor of the Fund's shares.

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


     At March 31, 2008, four shareholders of record, (including MBC Investment
     Corp., a wholly-owned subsidiary of BNY Mellon and an affiiliate of the
     Fund) in the aggregate held approximately 88.7% of the total outstanding
     shares of the Fund. Investment activities of these shareholders could have
     a material impact on the Fund. For example, a significant redemption by
     such shareholders could result in illiquid or less liquid investments
     comprising a larger portion of the Fund's Portfolio.

     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 six months ended March 31, 2008, 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, were as follows:


                                                
        Cost for federal income tax purposes       $    15,665,710

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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 March 31, 2008, the Fund did not hold forward foreign currency exchange
     contracts.

(7)  Security Lending:

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

     Until December 10, 2007, all cash collateral received by the Fund and other
     series of the Trust in connection with the securities lending program was
     invested in the BlackRock Cash Strategies Fund LLC (the "BlackRock Fund"),
     a private investment fund not affiliated with the Trust or its investment
     adviser. On December 10, 2007, the BlackRock Fund announced that it was
     suspending investor withdrawal privileges due to conditions related to the
     credit markets and the adverse affect of such conditions on the liquidity
     of the BlackRock Fund's portfolio holdings. Commencing on December 11,
     2007, all new cash collateral received in connection with the securities
     lending activity of the Fund and other series of the Trust was invested by
     the securities lending agent in the Dreyfus Institutional Cash Advantage
     Fund (the "Dreyfus Fund"), an affiliated money market fund registered as an
     investment company under the Investment Company Act of 1940, as amended. To
     the extent that the BlackRock Fund agreed to permit withdrawals during the
     period December 11, 2007 through March 31, 2008, the securities lending
     agent effected such withdrawals and the cash proceeds from such withdrawals
     by the Fund were reinvested in shares of the Dreyfus Fund. Repayments of
     cash collateral during the period were made from the proceeds of
     redemptions of shares of the Dreyfus Fund. See Schedule of Investments for
     further detail on the Fund's investment of cash collateral in the BlackRock
     Fund and the Dreyfus Fund as of March 31, 2008.

     The Fund loaned securities during the six months ended March 31, 2008 and
     earned interest on the invested collateral of $10,507 of which $8,021 was
     rebated to borrowers or paid in fees. 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. During the six months ended March 31, 2008,
     the Fund had average borrowings outstanding of $70,045 for a total of
     forty-four days and incurred $279 of interest expense. At March 31, 2008,
     the Fund had a $127,000 outstanding loan balance.

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

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. In their
     most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from the Fund's investment adviser, The
     Boston Company Asset Management LLC ("TBCAM" or the "Adviser"), a broad
     range of information in response to a written request prepared on their
     behalf by their own legal counsel. The Independent Trustees met alone in a
     private session with their legal counsel on September 27, 2007 to review
     these materials and to discuss the proposed continuation of the Fund's
     advisory agreement. Representatives of management attended a portion of the
     September meeting to provide an overview of the Adviser's organization,
     personnel, resources and strategic plans, and to respond to questions and
     comments arising from the Independent Trustees' review of the materials and
     their deliberations. The entire Board then met on October 30, 2007.

     The information requested by the Independent Trustees and reviewed by the
     entire Board included:

     (i) Financial and Economic Data: The Adviser's balance sheet and income
     statements, as well as a profitability analysis of the Adviser, including a
     separate presentation of the Adviser's profitability relative to that of
     several publicly traded investment advisers;

     (ii) Management Teams and Operations: The Adviser's Form ADV, as well as
     information concerning the Adviser's executive management, portfolio
     management, client service personnel and overall organizational structure,
     insurance coverage, brokerage and soft dollar policies and practices;

     (iii) Comparative Performance and Fees: Analyses prepared by Lipper
     Analytical Services ("Lipper") regarding the Fund's historical performance,
     management fee and expense ratio compared to other funds, and the Adviser's
     separate account advisory fee schedules;

     (iv) Specific Facts Relating to the Fund: The Adviser's commentary on the
     Fund's performance and any material portfolio manager and strategy changes
     that may have affected the Fund in the prior year, as well as the Fund's
     "fact sheets" prepared by the Adviser providing salient data about the
     Fund, including the Fund's holdings, strategies, recent market conditions
     and outlook, as well as the Adviser's views concerning the issues of
     breakpoints in the management fee schedule of the Fund and potential
     economies of scale; and

     (v) Other Benefits: The benefits flowing to The Bank of New York Mellon
     Corporation ("BNY Mellon") and its affiliates in the form of fees for
     transfer agency, custody, administration and securities lending services
     provided to the Funds by affiliates of BNY Mellon.

     In considering the continuation of the Fund's advisory agreement, the Board
     of Trustees, including the Independent Trustees, did not identify any
     single factor as all-important or controlling, and individual Trustees did
     not necessarily attribute the same weight or importance to each factor. The
     Trustees determined that the terms and conditions of the advisory agreement
     and the compensation to the Adviser provided therein were fair and
     reasonable in light of the services performed, expenses incurred and such
     other matters as the Trustees considered relevant in the exercise of their
     reasonable judgment. The following summary does not detail all the matters
     that were considered. Some of the factors that figured prominently in the
     Trustees' determination are described below.

     Nature, Extent and Quality of Services
     The Board considered the nature, scope and quality of the overall services
     provided to the Fund by the Adviser. In their deliberations as to the
     continuation of the advisory agreement, the Trustees were also mindful of
     the fact that, by choosing to invest in the Fund, the Fund's shareholders
     have chosen to entrust the Adviser, under the supervision of the Board, to
     manage the portion of their assets invested in the Fund.

     Among the specific factors the Board reviewed were the investment
     management, administrative, compliance and related services provided by the
     Adviser. The Board determined that the services provided were of high
     quality and at least commensurate with industry standards.

     The Trustees reviewed the background and experience of the Fund's portfolio
     manager and also met with senior management of the Adviser to receive an
     overview of its organization, personnel, resources and strategic plans.
     Among other things, the Trustees considered the size, education and
     experience of the Adviser's investment staff, technological infrastructure
     and overall responsiveness to changes in market conditions.

     The Board determined that the Adviser had the expertise and resources to
     manage the Fund effectively.

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

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Investment Performance
     The Board considered the investment performance of the Fund against a peer
     group of investment companies selected by the Adviser with input from the
     Trustees. The Board also compared the Fund's investment performance against
     the average performance of a larger universe of funds regarded by Lipper as
     having similar investment objectives and considered the Fund's performance
     rankings against that universe. In addition to the information received by
     the Board at the September 27, 2007 Board meeting, the Trustees received
     similar detailed comparative performance information for the Fund at each
     regular Board meeting during the year.

     The Board considered the Fund's performance for the one-year period ended
     July 31, 2007 based on the Lipper materials provided to the Board at the
     September 27, 2007 meeting. The Board found that the Fund outperformed its
     peer group average return for the one-year period (53.11% vs. 48.04%). The
     Board noted that the Fund recently commenced operations and had a very
     short performance history and that the other funds in its peer group were
     substantially larger than the Fund.

     Advisory Fee and Other Expenses
     The Board considered the advisory fee rate paid by the Fund to the Adviser.
     The Lipper data presenting the Fund's "net management fees" included fees
     paid by the Fund, as calculated by Lipper, for administrative services
     provided by Mellon Bank, N.A., the Trust's custodian. Such reporting was
     necessary, according to Lipper, to allow the Board to compare the Fund's
     advisory fees to those peers that include administrative fees within a
     blended advisory fee.

     The Fund's contractual advisory fee was 1.10%, which was in the 3rd (1st
     being the best) quintile of its peer group of funds, the median fee of
     which was 1.11%. The Fund's entire management fee was reimbursed by the
     Adviser. By comparison, the peer group median net management fee was
     1.108%. Based on the Lipper data, as well as other factors discussed at the
     September 27, 2007 meeting, the Board determined that the Fund's advisory
     fee is reasonable relative to its peer group averages.

     The Board also compared the fees payable by the Fund relative to those
     payable by separate account clients of the Adviser. Based on the additional
     scope and complexity of the services provided and responsibilities assumed
     by the Adviser with respect to the Fund relative to these other types of
     clients, the Board concluded that the fees payable under the advisory
     agreement were reasonable relative to the nature and quality of the
     services provided.

     The Board also considered the Fund's expense ratio and compared it to that
     of its peer group of similar funds. The Board found that the actual net
     expense ratio of 1.45% (after giving effect to expense limitations) was
     slightly higher than the median net expense ratio of the peer group of
     1.428%, largely due to the Fund's small asset size compared to its peer
     group.

     The Adviser's Profitability
     The Board considered the Adviser's profitability in managing the Fund and
     the Mellon Institutional Funds as a group, as well as the methodology used
     to compute such profitability, and the various direct and indirect expenses
     incurred by the Adviser or its affiliated investment advisers in managing
     the Fund and other funds in the Mellon Institutional Funds family of funds.
     The Independent Trustees had observed that the Adviser, based on the
     profitability information submitted to them by the Adviser, incurred losses
     in managing many of the investment companies in the Mellon Institutional
     Funds family of funds. The Trustees observed that the Adviser had incurred
     a loss in operating the Fund in 2006.

     Economies of Scale
     The Board also considered the extent to which economies of scale might be
     realized as the Fund grows. They observed that the Standish Mellon Fixed
     Income Fund and The Boston Company International Core Equity Fund, two of
     the largest funds in the complex, already had breakpoints in their fee
     arrangements that reflected economies resulting from their size. The Board
     also noted that at the March 7, 2006 meeting, management had presented a
     Breakpoint Discussion Memorandum that had proposed a framework for future
     breakpoints. The Board concluded that, at existing asset levels and
     considering current asset growth projections, the implementation of
     additional fee breakpoints or other fee reductions was not necessary at
     this time.

              Factors Considered by the Trustees in Approving the
                    Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Other Benefits
     The Board also considered the additional benefits flowing to BNY Mellon as
     a result of its relationship with the Mellon Institutional Funds as a
     group, including revenues received by BNY Mellon affiliates in
     consideration of custodial, administrative, transfer agency and securities
     lending services provided by such affiliates to the Funds. In each case,
     such affiliates were selected by the Board on the basis of a comparative
     analysis of their capabilities and fees relative to those of unaffiliated
     competitors.

     The Board considered the fact that BNY Mellon operates businesses other
     than the Mellon Institutional Funds, some of which businesses share
     personnel, office space and other resources and that these were a component
     of the profitability analysis provided. The Board also considered the
     intangible benefits that accrue to BNY Mellon and its affiliates by virtue
     of its relationship with the Funds and the Mellon Institutional Funds as a
     group.

                                      * * *

     The foregoing factors were among those weighed by the Trustees in
     determining that the terms and conditions of the Fund's advisory agreement
     and the compensation to the Adviser provided therein are fair and
     reasonable and, thus, in approving the continuation of the agreement for a
     one-year period.

                          Mellon Capital Micro Cap 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 (October 1, 2007 to March 31, 2008).

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 Paid

- ----------
+    Expenses are equal to the Fund's annualized expense ratio of 1.35%,
     multiplied by the average account value over the period, multiplied by
     183/366 (to reflect the one-half year period).

                   Mellon Institutional Funds Investment Trust
                          Mellon Capital Micro Cap Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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 Capital Micro Cap Fund (the "Fund"), which commenced operations on
     May 1, 2006, is a separate diversified investment series of the Trust.

     Through December 31, 2007, Mellon Equity Associates LLP ("Mellon Equity")
     had served as the investment adviser to the Fund. Effective on that date,
     Mellon Equity and Mellon Capital Management Corporation ("Mellon Capital"),
     each a wholly-owned subsidiary of The Bank of New York Mellon Corporation
     ("BNY Mellon"), merged into one surviving investment adviser, Mellon
     Capital. After the merger, Mellon Capital remains an indirect wholly-owned
     subsidiary of BNY Mellon. Effective January 1, 2008, Mellon Capital
     replaced Mellon Equity as the investment adviser to the Fund and the Fund
     changed its name from "Mellon Equity Micro Cap Fund." There have been no
     changes to the terms of the investment advisory agreement or to the
     portfolio manager line-up of the Fund.

     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.

                   Mellon Institutional Funds Investment Trust
                          Mellon Capital Micro Cap Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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.

     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 Capital, a
     wholly-owned subsidiary of BNY Mellon, or its affiliates.

     G. 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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes has
     not yet been determined.

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

     The investment advisory fee paid to Mellon Capital 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 Capital 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 six months ended March 31, 2008. Pursuant to this arrangement, for the
     six months ended March 31, 2008, Mellon Capital voluntarily waived its
     investment advisory fee in the amount of $42,729 and reimbursed the Fund
     for $8,003 of its operating expenses. This arrangement is voluntary and
     temporary and may be discontinued or revised by Mellon Capital 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 Capital, to provide
     personnel and facilities to perform transfer agency and certain shareholder
     services for the Fund. For these services the Fund pays Dreyfus Transfer,
     Inc. a fixed fee plus per account and transaction based fees, as well as,
     out-of-pocket expenses. Pursuant to this agreement, the Fund was charged
     $3,098, for the six months ended March 31, 2008.

     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 Capital,
     to provide custody, administration and fund accounting services for the
     Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset
     and transaction based fees, as well as out-of-pocket expenses. Pursuant to
     this agreement, the Fund was charged $25,095 for the six months ended March
     31, 2008.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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 $3,784 for the six
     months ended March 31, 2008. 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 $29
     for the six months ended March 31, 2008, which 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 six months ended
     March 31, 2008, the Fund was charged $2,130, which amount is included in
     miscellaneous expenses in the statement of operations. No other director,
     officer or employee of Mellon Capital 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 Capital 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
     six months ended March 31, 2008, 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 Capital, to provide
     printing and fulfillment services for the Fund. Pursuant to this agreement,
     the Fund was charged $1,220, which amount is included in miscellaneous
     expenses in the Statement of Operations, for the six months ended March 31,
     2008.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of Mellon Capital, is the distributor of the Fund's
     shares.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the six months ended March 31, 2008 were as follows:

                   Mellon Institutional Funds Investment Trust
                          Mellon Capital Micro Cap Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     At March 31, 2008, two shareholders of record (including MBC Investments
     Corp., a wholly-owned subsidiary of BNY Mellon and an affiliate of Mellon
     Capital which holds approximately 54%), in the aggregate held approximately
     98.8% of the total outstanding shares of the Fund. Investment activities of
     these shareholders could have a material impact on the Fund. For example, a
     significant redemption by such shareholders could result in illiquid or
     less liquid investments comprising a larger portion of the Fund's
     Portfolio.

     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 six months ended March 31, 2008, 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 Internal Revenue 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, were as follows:


                                                        
        Cost for federal income tax purposes               $  9,327,081
                                                           ============
        Gross unrealized appreciation                      $    408,145
        Gross unrealized depreciation                          (895,323)
                                                           ------------
        Net unrealized appreciation (depreciation)         $   (487,178)
                                                           ============


(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.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     Until December 10, 2007, all cash collateral received by the Fund and other
     series of the Trust in connection with the securities lending program was
     invested in the BlackRock Cash Strategies Fund LLC (the "BlackRock Fund"),
     a private investment fund not affiliated with the Trust or its investment
     adviser. On December 10, 2007, the BlackRock Fund announced that it was
     suspending investor withdrawal privileges due to conditions related to the
     credit markets and the adverse affect of such conditions on the liquidity
     of the BlackRock Fund's portfolio holdings. Commencing on December 11,
     2007, all new cash collateral received in connection with the securities
     lending activity of the Fund and other series of the Trust was invested by
     the securities lending agent in the Dreyfus Institutional Cash Advantage
     Fund (the "Dreyfus Fund"), an affiliated money market fund registered as an
     investment company under the Investment Company Act of 1940, as amended. To
     the extent that the BlackRock Fund agreed to permit withdrawals during the
     period December 11, 2007 through March 31, 2008, the securities lending
     agent effected such withdrawals and the cash proceeds from such withdrawals
     by the Fund were reinvested in shares of the Dreyfus Fund. Repayments of
     cash collateral during the period were made from the proceeds of
     redemptions of shares of the Dreyfus Fund. See Schedule of Investments for
     further detail on the Fund's investment of cash collateral in the BlackRock
     Fund and the Dreyfus Fund as of March 31, 2008.

     The Fund loaned securities during the six months ended March 31, 2008 and
     earned interest on the invested collateral of $25,121 of which $16,295 was
     rebated to borrowers or paid in fees. 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. During the six months ended March 31, 2008,
     the Fund had average borrowings outstanding of $6,500 for a total of two
     days and incurred $0 of interest expense. At March 31, 2008, the Fund did
     not have a loan balance outstanding.

                          Mellon Capital Micro Cap Fund

              Factors Considered by the Trustees in Approving the
                    Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. In their
     most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from the Fund's investment adviser, Mellon
     Capital Corporation ("Mellon Capital" or the "Adviser"), a broad range of
     information in response to a written request prepared on their behalf by
     their own legal counsel. The Independent Trustees met alone in a private
     session with their legal counsel on September 27, 2007 to review these
     materials and to discuss the proposed continuation of the Fund's advisory
     agreement. Representatives of management attended a portion of the
     September meeting to provide an overview of the Adviser's organization,
     personnel, resources and strategic plans, and to respond to questions and
     comments arising from the Independent Trustees' review of the materials and
     their deliberations. The entire Board then met on October 30, 2007.

     The information requested by the Independent Trustees and reviewed by the
     entire Board included:

     (i) Financial and Economic Data: The Adviser's balance sheet and income
     statements, as well as a profitability analysis of the Adviser, including a
     separate presentation of the Adviser's profitability relative to that of
     several publicly traded investment advisers;

     (ii) Management Teams and Operations: The Adviser's Form ADV, as well as
     information concerning the Adviser's executive management, portfolio
     management, client service personnel and overall organizational structure,
     insurance coverage, brokerage and soft dollar policies and practices;

     (iii) Comparative Performance and Fees: Analyses prepared by Lipper
     Analytical Services ("Lipper") regarding the Fund's historical performance,
     management fee and expense ratio compared to other funds, and the Adviser's
     separate account advisory fee schedules;

     (iv) Specific Facts Relating to the Fund: The Adviser's commentary on the
     Fund's performance and any material portfolio manager and strategy changes
     that may have affected the Fund in the prior year, as well as the Fund's
     "fact sheets" prepared by the Adviser providing salient data about the
     Fund, including the Fund's holdings, strategies, recent market conditions
     and outlook, as well as the Adviser's views concerning the issues of
     breakpoints in the management fee schedule of the Fund and potential
     economies of scale; and

     (v) Other Benefits: The benefits flowing to The Bank of New York Mellon
     Corporation ("BNY Mellon") and its affiliates in the form of fees for
     transfer agency, custody, administration and securities lending services
     provided to the Funds by affiliates of BNY Mellon.

     In considering the continuation of the Fund's advisory agreement, the Board
     of Trustees, including the Independent Trustees, did not identify any
     single factor as all-important or controlling, and individual Trustees did
     not necessarily attribute the same weight or importance to each factor. The
     Trustees determined that the terms and conditions of the advisory agreement
     and the compensation to the Adviser provided therein were fair and
     reasonable in light of the services performed, expenses incurred and such
     other matters as the Trustees considered relevant in the exercise of their
     reasonable judgment. The following summary does not detail all the matters
     that were considered. Some of the factors that figured prominently in the
     Trustees' determination are described below.

     Nature, Extent and Quality of Services
     The Board considered the nature, scope and quality of the overall services
     provided to the Fund by the Adviser. In their deliberations as to the
     continuation of the advisory agreement, the Trustees were also mindful of
     the fact that, by choosing to invest in the Fund, the Fund's shareholders
     have chosen to entrust the Adviser, under the supervision of the Board, to
     manage the portion of their assets invested in the Fund.

     Among the specific factors the Board reviewed were the investment
     management, administrative, compliance and related services provided by the
     Adviser. The Board determined that the services provided were of high
     quality and at least commensurate with industry standards.

     The Trustees reviewed the background and experience of the Fund's two
     portfolio managers and also met with senior management of the Adviser to
     receive an overview of its organization, personnel, resources and strategic
     plans. Among other things, the Trustees considered the size, education and
     experience of the Adviser's investment staff, technological infrastructure
     and overall responsiveness to changes in market conditions.

     The Board determined that the Adviser had the expertise and resources to
     manage the Fund effectively.

     Investment Performance
     The Board considered the investment performance of the Fund against a peer
     group of investment companies selected by the Adviser with input from the
     Trustees. The Board also compared the Fund's investment performance against
     the average performance of a larger universe of funds regarded by Lipper as
     having similar investment objectives and considered the Fund's performance
     rankings against that universe. In addition to the information received by
     the Board at the September 27, 2007 Board meeting, the Trustees received
     similar detailed comparative performance information for the Fund at each
     regular Board meeting during the year.

     The Board considered the Fund's performance for the one-year period ended
     July 31, 2007 based on the Lipper materials provided to the Board at the
     September 27, 2007 meeting. The Board found that the Fund underperformed
     its peer group average return for the one-year period (9.52% vs. 14.46%).
     The Board noted that the Fund recently commenced operations and had a very
     short performance history and that the other funds in its peer group were
     substantially larger than the Fund.

                         Mellon Capital Micro Cap Fund

              Factors Considered by the Trustees in Approving the
                    Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Advisory Fee and Other Expenses
     The Board considered the advisory fee rate paid by the Fund to the Adviser.
     The Lipper data presenting the Fund's "net management fees" included fees
     paid by the Fund, as calculated by Lipper, for administrative services
     provided by Mellon Bank, N.A., the Trust's custodian. Such reporting was
     necessary, according to Lipper, to allow the Board to compare the Fund's
     advisory fees to those peers that include administrative fees within a
     blended advisory fee.

     The Fund's contractual advisory fee was 1.00%, which was in the 1st (best)
     quintile of its peer group of funds, the median fee of which was 1.212%.
     The Fund's net management fee (after giving effect to expense limitations)
     was 0.212% (which included administrative services fees under Lipper's
     calculation methodology), well below the peer group median net management
     fee of 1.158%. Based on the Lipper data, as well as other factors discussed
     at the September 27, 2007 meeting, the Board determined that the Fund's
     advisory fee is reasonable relative to its peer group averages.

     The Board also compared the fees payable by the Fund relative to those
     payable by separate account clients of the Adviser. Based on the additional
     scope and complexity of the services provided and responsibilities assumed
     by the Adviser with respect to the Fund relative to these other types of
     clients, the Board concluded that the fees payable under the advisory
     agreement were reasonable relative to the nature and quality of the
     services provided.

     The Board also considered the Fund's expense ratio and compared it to that
     of its peer group of similar funds. The Board found that the actual net
     expense ratio of 1.35% (after giving effect to expense limitations) was
     lower than the median net expense ratio of the peer group of 1.45%,
     notwithstanding the fact that most of the other funds in the peer group
     were larger than the Fund.

     The Adviser's Profitability
     The Board considered the Adviser's profitability in managing the Fund and
     the Mellon Institutional Funds as a group, as well as the methodology used
     to compute such profitability, and the various direct and indirect expenses
     incurred by the Adviser or its affiliated investment advisers in managing
     the Fund and other funds in the Mellon Institutional Funds family of funds.
     The Independent Trustees had observed that the Adviser, based on the
     profitability information submitted to them by the Adviser, incurred losses
     in managing many of the investment companies in the Mellon Institutional
     Funds family of funds. The Trustees observed that the Adviser had incurred
     a loss in operating the Fund in 2006.

     Economies of Scale
     The Board also considered the extent to which economies of scale might be
     realized as the Fund grows. They observed that the Standish Mellon Fixed
     Income Fund and The Boston Company International Core Equity Fund, two of
     the largest funds in the complex, already had breakpoints in their fee
     arrangements that reflected economies resulting from their size. The Board
     also noted that at the March 7, 2006 meeting, management had presented a
     Breakpoint Discussion Memorandum that had proposed a framework for future
     breakpoints. The Board concluded that, at existing asset levels and
     considering current asset growth projections, the implementation of
     additional fee breakpoints or other fee reductions was not necessary at
     this time.

     Other Benefits
     The Board also considered the additional benefits flowing to BNY Mellon as
     a result of its relationship with the Mellon Institutional Funds as a
     group, including revenues received by BNY Mellon affiliates in
     consideration of custodial, administrative, transfer agency and securities
     lending services provided by such affiliates to the Funds. In each case,
     such affiliates were selected by the Board on the basis of a comparative
     analysis of their capabilities and fees relative to those of unaffiliated
     competitors.

     The Board considered the fact that BNY Mellon operates businesses other
     than the Mellon Institutional Funds, some of which businesses share
     personnel, office space and other resources and that these were a component
     of the profitability analysis provided. The Board also considered the
     intangible benefits that accrue to BNY Mellon and its affiliates by virtue
     of its relationship with the Funds and the Mellon Institutional Funds as a
     group.

                                      * * *

     The foregoing factors were among those weighed by the Trustees in
     determining that the terms and conditions of the Fund's advisory agreement
     and the compensation to the Adviser provided therein are fair and
     reasonable and, thus, in approving the continuation of the agreement for a
     one-year period.

                   Mellon Institutional Funds Investment Trust
               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 (October 1, 2007 to March 31, 2008).

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 Paid

+ Expenses are equal to the Fund's annualized expense ratio of 0.88%,
  multiplied by the average account value over the period, multiplied by
  183/366 (to reflect the one-half year period).

               The Boston Company International Core Equity Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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.

     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.

     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, 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 (the "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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     application of FAS 161 is required for fiscal years beginning after
     November 15, 2008 and interim periods within those fiscal years. At this
     time, management is evaluating the implications of FAS 161 and its impact
     on the financial statements and the accompanying notes 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 first $500 million of the Fund'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 October 1, 2007 through August 31, 2008, TBCAM has agreed
     to rebate 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 six months ended March 31, 2008 TBCAM rebated
     $624,657 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
     $49,520, for the six months ended March 31, 2008.

     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 fund accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $158,718 for the six months ended March 31,
     2008.

     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 $140 for the six
     months ended March 31, 2008. See Note 7 for further details.

     The 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
     $43,991 for the six months ended March 31, 2008, 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 six months ended
     March 31, 2008, the Fund was charged $2,123, 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 $8,000, which amount is included in miscellaneous expenses in the
     statement of operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was charged $60,549 for fees
     payable to BNY Mellon Wealth Management.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of TBCAM, is the distributor of the Fund's shares.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the six months ended March 31, 2008 were as follows:

(4)  Shares of Beneficial Interest:

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



                                                 For the
                                            Six Months Ended         For the

                                              (Unaudited)       September 30, 2007

     At March 31, 2008, two shareholders of record, in the aggregate, held
     approximately 26.1% of the total outstanding shares of the Fund. Investment
     activities of these shareholders could have a material impact on the Fund.
     For example, a significant redemption by such shareholders could result in
     illiquid or less liquid investments comprising a larger portion of the
     Fund's Portfolio.

     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 six months ended March 31, 2008, the Fund received
     $41,319 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, were as follows:


                                                        
                  Cost for federal income tax purposes     $329,077,136

                  Gross unrealized appreciation              13,990,524
                  Gross unrealized depreciation             (30,189,593)
                                                           ------------
                  Net unrealized appreciation
                    (depreciation)                         $(16,199,069)
                                                           ============


(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


                                       18



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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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.

     For the six months ended March 31, 2008, the Fund held open financial
     futures contracts. See the Schedule of Investments for further details.

     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.

     For the six months ended March 31, 2008, 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 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.

     Until December 10, 2007, all cash collateral received by the Fund and other
     series of the Trust in connection with the securities lending program was
     invested in the BlackRock Cash Strategies Fund LLC (the "BlackRock Fund"),
     a private investment fund not affiliated with the Trust or its investment
     adviser. On December 10, 2007, the BlackRock Fund announced that it was
     suspending investor withdrawal privileges due to conditions related to the
     credit markets and the adverse affect of such conditions on the liquidity
     of the BlackRock Fund's portfolio holdings. Commencing on December 11,
     2007, all new cash collateral received in connection with the securities
     lending activity of the Fund and other series of the Trust was invested by
     the securities lending agent in the Dreyfus Institutional Cash Advantage
     Fund (the "Dreyfus Fund"), an affiliated money market fund registered as an
     investment company under the Investment Company Act of 1940, as amended. To
     the extent that the BlackRock Fund agreed to permit withdrawals during the
     period December 11, 2007 through March 31, 2008, the securities lending
     agent effected such withdrawals and the cash proceeds from such withdrawals
     by the Fund were reinvested in shares of the Dreyfus Fund. Repayments of
     cash collateral during the period were made from the proceeds of
     redemptions of shares of the Dreyfus Fund. See Schedule of Investments for
     further detail on the Fund's investment of cash collateral in the BlackRock
     Fund and the Dreyfus Fund as of March 31, 2008.

     The Fund loaned securities during the six months ended March 31, 2008 and
     earned interest on the invested collateral of $1,661 of which $1,393 was
     rebated to borrowers or paid in fees. 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 six months ended March 31, 2008, the
     Fund had average borrowings outstanding of $12,436,000 for a total of 18
     days and incurred interest expense of $30,911. At March 31, 2008, the Fund
     did not have a loan balance outstanding.

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. In their
     most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from the Fund's investment adviser, The
     Boston Company Asset Management LLC ("TBCAM" or the "Adviser"), a broad
     range of information in response to a written request prepared on their
     behalf by their own legal counsel. The Independent Trustees met alone in a
     private session with their legal counsel on September 27, 2007 to review
     these materials and to discuss the proposed continuation of the Fund's
     advisory agreement. Representatives of management attended a portion of the
     September meeting to provide an overview of the Adviser's organization,
     personnel, resources and strategic plans, and to respond to questions and
     comments arising from the Independent Trustees' review of the materials and
     their deliberations. The entire Board then met on October 30, 2007.

     The information requested by the Independent Trustees and reviewed by the
     entire Board included:

     (i) Financial and Economic Data: The Adviser's balance sheet and income
     statements, as well as a profitability analysis of the Adviser, including a
     separate presentation of the Adviser's profitability relative to that of
     several publicly traded investment advisers;

     (ii) Management Teams and Operations: The Adviser's Form ADV, as well as
     information concerning the Adviser's executive management, portfolio
     management, client service personnel and overall organizational structure,
     insurance coverage, brokerage and soft dollar policies and practices;

     (iii) Comparative Performance and Fees: Analyses prepared by Lipper
     Analytical Services ("Lipper") regarding the Fund's historical performance,
     management fee and expense ratio compared to other funds, and the Adviser's
     separate account advisory fee schedules;

     (iv) Specific Facts Relating to the Fund: The Adviser's commentary on the
     Fund's performance and any material portfolio manager and strategy changes
     that may have affected the Fund in the prior year, as well as the Fund's
     "fact sheets" prepared by the Adviser providing salient data about the
     Fund, including the Fund's holdings, strategies, recent market conditions
     and outlook, as well as the Adviser's views concerning the issues of
     breakpoints in the management fee schedule of the Fund and potential
     economies of scale; and

     (v) Other Benefits: The benefits flowing to The Bank of New York Mellon
     Corporation ("BNY Mellon") and its affiliates in the form of fees for
     transfer agency, custody, administration and securities lending services
     provided to the Funds by affiliates of BNY Mellon.

     In considering the continuation of the Fund's advisory agreement, the Board
     of Trustees, including the Independent Trustees, did not identify any
     single factor as all-important or controlling, and individual Trustees did
     not necessarily attribute the same weight or importance to each factor. The
     Trustees determined that the terms and conditions of the advisory agreement
     and the compensation to the Adviser provided therein were fair and
     reasonable in light of the services performed, expenses incurred and such
     other matters as the Trustees considered relevant in the exercise of their
     reasonable judgment. The following summary does not detail all the matters
     that were considered. Some of the factors that figured prominently in the
     Trustees' determination are described below.

     Nature, Extent and Quality of Services

     The Board considered the nature, scope and quality of the overall services
     provided to the Fund by the Adviser. In their deliberations as to the
     continuation of the advisory agreement, the Trustees were also mindful of
     the fact that, by choosing to invest in the Fund, the Fund's shareholders
     have chosen to entrust the Adviser, under the supervision of the Board, to
     manage the portion of their assets invested in the Fund.

     Among the specific factors the Board reviewed were the investment
     management, administrative, compliance and related services provided by the
     Adviser. The Board determined that the services provided were of high
     quality and at least commensurate with industry standards.

     The Trustees reviewed the background and experience of the Fund's portfolio
     manager and also met with senior management of the Adviser to receive an
     overview of its organization, personnel, resources and strategic plans.
     Among other things, the Trustees considered the size, education and
     experience of the Adviser's investment staff, technological infrastructure
     and overall responsiveness to changes in market conditions.

     The Board determined that the Adviser had the expertise and resources to
     manage the Fund effectively.

     Investment Performance

     The Board considered the investment performance of the Fund against a peer
     group of investment companies selected by the Adviser with input from the
     Trustees. The Board also compared the Fund's investment performance against
     the average performance of a larger universe of funds regarded by Lipper as
     having similar investment objectives and considered the Fund's performance
     rankings against that universe. In addition to the information received by
     the Board at the September 27, 2007 Board meeting, the Trustees received
     similar detailed comparative performance information for the Fund at each
     regular Board meeting during the year.

     The Board considered the Fund's performance for the one-, three- and
     five-year periods ended July 31, 2007 based on the Lipper materials
     provided to the Board at the September 27, 2007 meeting. The Board found
     that the Fund outperformed its peer group average return for the one-year
     period (24.11% vs. 23.60%), three-year period (25.25% vs. 22.59%) and
     five-year period (22.73% vs. 18.50%).

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

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Advisory Fee and Other Expenses

     The Board considered the advisory fee rate paid by the Fund to the Adviser.
     The Lipper data presenting the Fund's "net management fees" included fees
     paid by the Fund, as calculated by Lipper, for administrative services
     provided by Mellon Bank, N.A., the Trust's custodian. Such reporting was
     necessary, according to Lipper, to allow the Board to compare the Fund's
     advisory fees to those peers that include administrative fees within a
     blended advisory fee.

     The Fund's effective contractual advisory fee was 0.725% (based on the
     following breakpoints: 0.80% of the first $500 million; 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% of over $2 billion), which was in the 3rd (1st being the
     best) quintile of its peer group of funds, the median fee of which was
     0.803%. The Fund's net management fee was 0.75% (which included
     administrative services fees under Lipper's calculation methodology), above
     the peer group median net management fee of 0.668%. Based on the Lipper
     data, as well as other factors discussed at the September 27, 2007 meeting,
     the Board determined that the Fund's advisory fee is reasonable relative to
     its peer group averages.

     The Board also compared the fees payable by the Fund relative to those
     payable by separate account clients of the Adviser. Based on the additional
     scope and complexity of the services provided and responsibilities assumed
     by the Adviser with respect to the Fund relative to these other types of
     clients, the Board concluded that the fees payable under the advisory
     agreement were reasonable relative to the nature and quality of the
     services provided.

     The Board also considered the Fund's expense ratio and compared it to that
     of its peer group of similar funds. The Board found that the actual net
     expense ratio of 0.879% was lower than the median net expense ratio of the
     peer group of 1.003%, notwithstanding the fact that many of the other funds
     in the peer group were larger than the Fund.

     The Adviser's Profitability

     The Board considered the Adviser's profitability in managing the Fund and
     the Mellon Institutional Funds as a group, as well as the methodology used
     to compute such profitability, and the various direct and indirect expenses
     incurred by the Adviser or its affiliated investment advisers in managing
     the Fund and other funds in the Mellon Institutional Funds family of funds.
     The Independent Trustees had observed that the Adviser, based on the
     profitability information submitted to them by the Adviser, incurred losses
     in managing many of the investment companies in the Mellon Institutional
     Funds family of funds. The Trustees observed that the Adviser had incurred
     gains in operating the Fund in 2005 and 2006.

     Economies of Scale

     The Board also considered the extent to which economies of scale might be
     realized as the Fund grows. They observed that the Fund and the Standish
     Mellon Fixed Income Fund, two of the largest funds in the complex, already
     had breakpoints in their fee arrangements that reflected economies
     resulting from their size. The Board also noted that at the March 7, 2006
     meeting, management had presented a Breakpoint Discussion Memorandum that
     had proposed a framework for future breakpoints. The Board concluded that,
     at existing asset levels and considering current asset growth projections,
     the implementation of additional fee breakpoints or other fee reductions
     was not necessary at this time.

     Other Benefits

     The Board also considered the additional benefits flowing to BNY Mellon as
     a result of its relationship with the Mellon Institutional Funds as a
     group, including revenues received by BNY Mellon affiliates in
     consideration of custodial, administrative, transfer agency and securities
     lending services provided by such affiliates to the Funds. In each case,
     such affiliates were selected by the Board on the basis of a comparative
     analysis of their capabilities and fees relative to those of unaffiliated
     competitors.

     The Board considered the fact that BNY Mellon operates businesses other
     than the Mellon Institutional Funds, some of which businesses share
     personnel, office space and other resources and that these were a component
     of the profitability analysis provided. The Board also considered the
     intangible benefits that accrue to BNY Mellon and its affiliates by virtue
     of its relationship with the Funds and the Mellon Institutional Funds as a
     group.

                                      * * *

     The foregoing factors were among those weighed by the Trustees in
     determining that the terms and conditions of the Fund's advisory agreement
     and the compensation to the Adviser provided therein are fair and
     reasonable and, thus, in approving the continuation of the agreement for a
     one-year period.

                   Mellon Institutional Funds Investment Trust
                  The Boston Company Small/Mid Cap Growth 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 (October 1, 2007 to March 31, 2008).

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/Mid Cap Growth Fund

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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 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 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.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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

     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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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 six months ended March
     31, 2008. Pursuant to this arrangement, for the six months ended March 31,
     2008, TBCAM voluntarily waived a portion of its investment advisory fee in
     the amount of $25,668. 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
     $3,464, for the six months ended March 31, 2008.

     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 fund accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $33,633 for the six months ended March 31,
     2008.

     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 $5,023 for the six
     months ended March 31, 2008. See Note 7 for further details.

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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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
     $452 for the six months ended March 31, 2008, 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 six months ended
     March 31, 2008, the Fund was charged $2,130, 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 $250, which amount is included in miscellaneous expenses in the
     Statement of Operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was charged $747 for fees payable
     to BNY Mellon Wealth Management.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of TBCAM, is the distributor of the Fund's shares.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the six months ended March 31, 2008 were as follows:

(4)  Shares of Beneficial Interest:

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

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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     At March 31, 2008, two shareholders of record, in the aggregate held
     approximately 72% of the total outstanding shares of the Fund. Investment
     activities of these shareholders could have a material impact on the Fund.
     For example, a significant redemption by such shareholders could result in
     illiquid or less liquid investments comprising a larger portion of the
     Fund's Portfolio.

     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 six months ended March 31, 2008, the Fund charged
     $404 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 Internal Revenue 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, were as follows:


                                                        
                  Cost for federal income tax purposes     $ 37,213,940

(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 (Unaudited)
- --------------------------------------------------------------------------------

     At March 31, 2008, the Fund did not hold open financial futures contracts.

(7)  Security Lending:

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

     Until December 10, 2007, all cash collateral received by the Fund and other
     series of the Trust in connection with the securities lending program was
     invested in the BlackRock Cash Strategies Fund LLC (the "BlackRock Fund"),
     a private investment fund not affiliated with the Trust or its investment
     adviser. On December 10, 2007, the BlackRock Fund announced that it was
     suspending investor withdrawal privileges due to conditions related to the
     credit markets and the adverse affect of such conditions on the liquidity
     of the BlackRock Fund's portfolio holdings. Commencing on December 11,
     2007, all new cash collateral received in connection with the securities
     lending activity of the Fund and other series of the Trust was invested by
     the securities lending agent in the Dreyfus Institutional Cash Advantage
     Fund (the "Dreyfus Fund"), an affiliated money market fund registered as an
     investment company under the Investment Company Act of 1940, as amended. To
     the extent that the BlackRock Fund agreed to permit withdrawals during the
     period December 11, 2007 through March 31, 2008, the security lending agent
     effected such withdrawals and the cash proceeds from such withdrawals by
     the Fund were reinvested in shares of the Dreyfus Fund. Repayments of cash
     collateral during the period were made from the proceeds of redemptions of
     shares of the Dreyfus Fund. See Schedule of Investments for further detail
     on the Fund's investment of cash collateral in the BlackRock Fund and the
     Dreyfus Fund as of March 31, 2008.

     The Fund loaned securities during the six months ended March 31, 2008 and
     earned interest on the invested collateral of $47,361 of which $35,725 was
     rebated to borrowers or paid in fees. 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. During the six months ended March 31, 2008,
     the Fund had average borrowings outstanding of $3,062,000 for a total of
     two days and incurred $2,656 of interest expense. The Fund did not have an
     outstanding loan balance at March 31, 2008.

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. In their
     most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from the Fund's investment adviser, The
     Boston Company Asset Management LLC ("TBCAM" or the "Adviser"), a broad
     range of information in response to a written request prepared on their
     behalf by their own legal counsel. The Independent Trustees met alone in a
     private session with their legal counsel on September 27, 2007 to review
     these materials and to discuss the proposed continuation of the Fund's
     advisory agreement. Representatives of management attended a portion of the
     September meeting to provide an overview of the Adviser's organization,
     personnel, resources and strategic plans, and to respond to questions and
     comments arising from the Independent Trustees' review of the materials and
     their deliberations. The entire Board then met on October 30, 2007.

     The information requested by the Independent Trustees and reviewed by the
     entire Board included:

     (i) Financial and Economic Data: The Adviser's balance sheet and income
     statements, as well as a profitability analysis of the Adviser, including a
     separate presentation of the Adviser's profitability relative to that of
     several publicly traded investment advisers;

     (ii) Management Teams and Operations: The Adviser's Form ADV, as well as
     information concerning the Adviser's executive management, portfolio
     management, client service personnel and overall organizational structure,
     insurance coverage, brokerage and soft dollar policies and practices;

     (iii) Comparative Performance and Fees: Analyses prepared by Lipper
     Analytical Services ("Lipper") regarding the Fund's historical performance,
     management fee and expense ratio compared to other funds, and the Adviser's
     separate account advisory fee schedules;

     (iv) Specific Facts Relating to the Fund: The Adviser's commentary on the
     Fund's performance and any material portfolio manager and strategy changes
     that may have affected the Fund in the prior year, as well as the Fund's
     "fact sheets" prepared by the Adviser providing salient data about the
     Fund, including the Fund's holdings, strategies, recent market conditions
     and outlook, as well as the Adviser's views concerning the issues of
     breakpoints in the management fee schedule of the Fund and potential
     economies of scale; and

     (v) Other Benefits: The benefits flowing to The Bank of New York Mellon
     Corporation ("BNY Mellon") and its affiliates in the form of fees for
     transfer agency, custody, administration and securities lending services
     provided to the Funds by affiliates of BNY Mellon.

     In considering the continuation of the Fund's advisory agreement, the Board
     of Trustees, including the Independent Trustees, did not identify any
     single factor as all-important or controlling, and individual Trustees did
     not necessarily attribute the same weight or importance to each factor. The
     Trustees determined that the terms and conditions of the advisory agreement
     and the compensation to the Adviser provided therein were fair and
     reasonable in light of the services performed, expenses incurred and such
     other matters as the Trustees considered relevant in the exercise of their
     reasonable judgment. The following summary does not detail all the matters
     that were considered. Some of the factors that figured prominently in the
     Trustees' determination are described below.

     Nature, Extent and Quality of Services

     The Board considered the nature, scope and quality of the overall services
     provided to the Fund by the Adviser. In their deliberations as to the
     continuation of the advisory agreement, the Trustees were also mindful of
     the fact that, by choosing to invest in the Fund, the Fund's shareholders
     have chosen to entrust the Adviser, under the supervision of the Board, to
     manage the portion of their assets invested in the Fund.

     Among the specific factors the Board reviewed were the investment
     management, administrative, compliance and related services provided by the
     Adviser. The Board determined that the services provided were of high
     quality and at least commensurate with industry standards.

     The Trustees reviewed the background and experience of the Fund's two
     portfolio managers and also met with senior management of the Adviser to
     receive an overview of its organization, personnel, resources and strategic
     plans. Among other things, the Trustees considered the size, education and
     experience of the Adviser's investment staff, technological infrastructure
     and overall responsiveness to changes in market conditions.

     The Board determined that the Adviser had the expertise and resources to
     manage the Fund effectively.

     Investment Performance

     The Board considered the investment performance of the Fund against a peer
     group of investment companies selected by the Adviser with input from the
     Trustees. The Board also compared the Fund's investment performance against
     the average performance of a larger universe of funds regarded by Lipper as
     having similar investment objectives and considered the Fund's performance
     rankings against that universe. In addition to the information received by
     the Board at the September 27, 2007 Board meeting, the Trustees received
     similar detailed comparative performance information for the Fund at each
     regular Board meeting during the year.

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The Board considered the Fund's performance for the one-, three- and
     five-year periods ended July 31, 2007 based on the Lipper materials
     provided to the Board at the September 27, 2007 meeting. The Board found
     that the Fund outperformed its peer group average return for the one-year
     period (23.02% vs. 21.00%), three-year period (17.14% vs. 15.64%) and
     five-year period (18.76% vs. 15.56%)

     Advisory Fee and Other Expenses

     The Board considered the advisory fee rate paid by the Fund to the Adviser.
     The Lipper data presenting the Fund's "net management fees" included fees
     paid by the Fund, as calculated by Lipper, for administrative services
     provided by Mellon Bank, N.A., the Trust's custodian. Such reporting was
     necessary, according to Lipper, to allow the Board to compare the Fund's
     advisory fees to those peers that include administrative fees within a
     blended advisory fee.

     The Fund's contractual advisory fee was 0.60%, which was in the 1st (best)
     quintile of its peer group of funds, the median fee of which was 0.701%.
     The Fund's net management fee (after giving effect to expense
     reimbursements) was 0.382% (which included administrative services fees
     under Lipper's calculation methodology), below the peer group median net
     management fee of 0.563%. Based on the Lipper data, as well as other
     factors discussed at the September 27, 2007 meeting, the Board determined
     that the Fund's advisory fee is reasonable relative to its peer group
     averages.

     The Board also compared the fees payable by the Fund relative to those
     payable by separate account clients of the Adviser. Based on the additional
     scope and complexity of the services provided and responsibilities assumed
     by the Adviser with respect to the Fund relative to these other types of
     clients, the Board concluded that the fees payable under the advisory
     agreement were reasonable relative to the nature and quality of the
     services provided.

     The Board also considered the Fund's expense ratio and compared it to that
     of its peer group of similar funds. The Board found that the actual net
     expense ratio of 1.00% (after giving effect to expense reimbursements) was
     slightly higher than the median net expense ratio of the peer group of
     0.99%, largely due to the Fund's small asset size compared to its peer
     group.

     The Adviser's Profitability

     The Board considered the Adviser's profitability in managing the Fund and
     the Mellon Institutional Funds as a group, as well as the methodology used
     to compute such profitability, and the various direct and indirect expenses
     incurred by the Adviser or its affiliated investment advisers in managing
     the Fund and other funds in the Mellon Institutional Funds family of funds.
     The Independent Trustees had observed that the Adviser, based on the
     profitability information submitted to them by the Adviser, incurred losses
     in managing many of the investment companies in the Mellon Institutional
     Funds family of funds. The Trustees observed that the Adviser had incurred
     losses in operating the Fund in 2005 and 2006.

     Economies of Scale

     The Board also considered the extent to which economies of scale might be
     realized as the Fund grows. They observed that the Standish Mellon Fixed
     Income Fund and The Boston Company International Core Equity Fund, two of
     the largest funds in the complex, already had breakpoints in their fee
     arrangements that reflected economies resulting from their size. The Board
     also noted that at the March 7, 2006 meeting, management had presented a
     Breakpoint Discussion Memorandum that had proposed a framework for future
     breakpoints. The Board concluded that, at existing asset levels and
     considering current asset growth projections, the implementation of
     additional fee breakpoints or other fee reductions was not necessary at
     this time.

     Other Benefits

     The Board also considered the additional benefits flowing to BNY Mellon as
     a result of its relationship with the Mellon Institutional Funds as a
     group, including revenues received by BNY Mellon affiliates in
     consideration of custodial, administrative, transfer agency and securities
     lending services provided by such affiliates to the Funds. In each case,
     such affiliates were selected by the Board on the basis of a comparative
     analysis of their capabilities and fees relative to those of unaffiliated
     competitors.

     The Board considered the fact that BNY Mellon operates businesses other
     than the Mellon Institutional Funds, some of which businesses share
     personnel, office space and other resources and that these were a component
     of the profitability analysis provided. The Board also considered the
     intangible benefits that accrue to BNY Mellon and its affiliates by virtue
     of its relationship with the Funds and the Mellon Institutional Funds as a
     group.

                                      * * *

     The foregoing factors were among those weighed by the Trustees in
     determining that the terms and conditions of the Fund's advisory agreement
     and the compensation to the Adviser provided therein are fair and
     reasonable and, thus, in approving the continuation of the agreement for a
     one-year period.

                     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 (October 1, 2007 to March 31, 2008).

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 Paid

+    Expenses are equal to the Fund's annualized expense ratio of 0.83%,
     multiplied by the average account value over the period, multiplied by
     183/366 (to reflect the one-half year period).

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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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.

     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

     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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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
     $4,989, for the six months ended March 31, 2008.

     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 fund accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $49,691 for the six months ended March 31,
     2008.

     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
     $1,729 for the six months ended March 31, 2008, which amount is included in
     miscellaneous expenses on the statement of operations. See Note 7 for
     further details.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the six months ended
     March 31, 2008, the Fund was charged $2,130, 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 $1,357, which amount is included in miscellaneous expenses in the
     statement of operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was charged $69,146 for fees
     payable to BNY Mellon Wealth Management.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of TBCAM, is the distributor of the Fund's shares.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the six months ended March 31, 2008 were as follows:

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


(4)  Shares of Beneficial Interest:

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



                                               For the
                                           Six Months Ended          For the

     Shares sold                                  71,698               859,821

     At March 31, 2008, two shareholders of record, in the aggregate held
     approximately 68.5% of the total outstanding shares of the Fund. Investment
     activities of these shareholders could have a material impact on the Fund.
     For example, a significant redemption by such shareholders could result in
     illiquid or less liquid investments comprising a larger portion of the
     Fund's Portfolio.

     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 six months ended March 31, 2008, the Fund did not
     assess any redemption fees.

                    Notes to Financial Statements (Unaudited)

(5)  Federal Taxes:

     Each year, the Fund intends to qualify as a "regulated investment company"
     under Subchapter M of the Internal Revenue 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, were as follows:


                                                      
             Cost for federal income tax purposes        $88,353,663

             Gross unrealized appreciation               $ 7,985,154
             Gross unrealized depreciation                (7,470,302)
                                                         -----------

(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 March 31, 2008, the Fund did not hold 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. During the six months ended March 31, 2008,
     the Fund had average borrowings outstanding of $632,643 for a total of
     forty-two days and incurred $3,477 of interest expense. The Fund did not
     have an outstanding loan balance at March 31, 2008.

                     The Boston Company Large Cap Core Fund

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. In their
     most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from the Fund's investment adviser, The
     Boston Company Asset Management LLC ("TBCAM" or the "Adviser"), a broad
     range of information in response to a written request prepared on their
     behalf by their own legal counsel. The Independent Trustees met alone in a
     private session with their legal counsel on September 27, 2007 to review
     these materials and to discuss the proposed continuation of the Fund's
     advisory agreement. Representatives of management attended a portion of the
     September meeting to provide an overview of the Adviser's organization,
     personnel, resources and strategic plans, and to respond to questions and
     comments arising from the Independent Trustees' review of the materials and
     their deliberations. The entire Board then met on October 30, 2007.

     The information requested by the Independent Trustees and reviewed by the
     entire Board included:

     (i) Financial and Economic Data: The Adviser's balance sheet and income
     statements, as well as a profitability analysis of the Adviser, including a
     separate presentation of the Adviser's profitability relative to that of
     several publicly traded investment advisers;

     (ii) Management Teams and Operations: The Adviser's Form ADV, as well as
     information concerning the Adviser's executive management, portfolio
     management, client service personnel and overall organizational structure,
     insurance coverage, brokerage and soft dollar policies and practices;

     (iii) Comparative Performance and Fees: Analyses prepared by Lipper
     Analytical Services ("Lipper") regarding the Fund's historical performance,
     management fee and expense ratio compared to other funds, and the Adviser's
     separate account advisory fee schedules;

     (iv) Specific Facts Relating to the Fund: The Adviser's commentary on the
     Fund's performance and any material portfolio manager and strategy changes
     that may have affected the Fund in the prior year, as well as the Fund's
     "fact sheets" prepared by the Adviser providing salient data about the
     Fund, including the Fund's holdings, strategies, recent market conditions
     and outlook, as well as the Adviser's views concerning the issues of
     breakpoints in the management fee schedule of the Fund and potential
     economies of scale; and

     (v) Other Benefits: The benefits flowing to The Bank of New York Mellon
     Corporation ("BNY Mellon") and its affiliates in the form of fees for
     transfer agency, custody, administration and securities lending services
     provided to the Funds by affiliates of BNY Mellon.

     In considering the continuation of the Fund's advisory agreement, the Board
     of Trustees, including the Independent Trustees, did not identify any
     single factor as all-important or controlling, and individual Trustees did
     not necessarily attribute the same weight or importance to each factor. The
     Trustees determined that the terms and conditions of the advisory agreement
     and the compensation to the Adviser provided therein were fair and
     reasonable in light of the services performed, expenses incurred and such
     other matters as the Trustees considered relevant in the exercise of their
     reasonable judgment. The following summary does not detail all the matters
     that were considered. Some of the factors that figured prominently in the
     Trustees' determination are described below.

     Nature, Extent and Quality of Services

     The Board considered the nature, scope and quality of the overall services
     provided to the Fund by the Adviser. In their deliberations as to the
     continuation of the advisory agreement, the Trustees were also mindful of
     the fact that, by choosing to invest in the Fund, the Fund's shareholders
     have chosen to entrust the Adviser, under the supervision of the Board, to
     manage the portion of their assets invested in the Fund.

     Among the specific factors the Board reviewed were the investment
     management, administrative, compliance and related services provided by the
     Adviser. The Board determined that the services provided were of high
     quality and at least commensurate with industry standards.

     The Trustees reviewed the background and experience of the Fund's two
     portfolio managers and also met with senior management of the Adviser to
     receive an overview of its organization, personnel, resources and strategic
     plans. Among other things, the Trustees considered the size, education and
     experience of the Adviser's investment staff, technological infrastructure
     and overall responsiveness to changes in market conditions.

     The Board determined that the Adviser had the expertise and resources to
     manage the Fund effectively.

                     The Boston Company Large Cap Core Fund

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Investment Performance

     The Board considered the investment performance of the Fund against a peer
     group of investment companies selected by the Adviser with input from the
     Trustees. The Board also compared the Fund's investment performance against
     the average performance of a larger universe of funds regarded by Lipper as
     having similar investment objectives and considered the Fund's performance
     rankings against that universe. In addition to the information received by
     the Board at the September 27, 2007 Board meeting, the Trustees received
     similar detailed comparative performance information for the Fund at each
     regular Board meeting during the year.

     The Board considered the Fund's performance for the one-, three- and
     five-year periods ended July 31, 2007 based on the Lipper materials
     provided to the Board at the September 27, 2007 meeting. The Board found
     that the Fund outperformed its peer group average return for the one-year
     period (17.88% vs. 15.53%), three-year period (12.78% vs. 12.13%) and
     five-year period (11.82% vs. 11.43%).

     Advisory Fee and Other Expenses

     The Board considered the advisory fee rate paid by the Fund to the Adviser.
     The Lipper data presenting the Fund's "net management fees" included fees
     paid by the Fund, as calculated by Lipper, for administrative services
     provided by Mellon Bank, N.A., the Trust's custodian. Such reporting was
     necessary, according to Lipper, to allow the Board to compare the Fund's
     advisory fees to those peers that include administrative fees within a
     blended advisory fee.

     The Fund's contractual advisory fee was 0.50%, which was in the 1st (best)
     quintile of its peer group of funds, the median fee of which was 0.65%. The
     Fund's net management fee (after giving effect to expense reimbursements)
     was 0.438% (which included administrative services fees under Lipper's
     calculation methodology), below the peer group median net management fee of
     0.510%. Based on the Lipper data, as well as other factors discussed at the
     September 27, 2007 meeting, the Board determined that the Fund's advisory
     fee is reasonable relative to its peer group averages.

     The Board also compared the fees payable by the Fund relative to those
     payable by separate account clients of the Adviser. Based on the additional
     scope and complexity of the services provided and responsibilities assumed
     by the Adviser with respect to the Fund relative to these other types of
     clients, the Board concluded that the fees payable under the advisory
     agreement were reasonable relative to the nature and quality of the
     services provided.

     The Board also considered the Fund's expense ratio and compared it to that
     of its peer group of similar funds. The Board found that the actual net
     expense ratio of 0.896% (after giving effect to expense reimbursements) was
     slightly higher than the median net expense ratio of the peer group of
     0.895%, largely due to the Fund's small asset size compared to its peer
     group.

     The Adviser's Profitability

     The Board considered the Adviser's profitability in managing the Fund and
     the Mellon Institutional Funds as a group, as well as the methodology used
     to compute such profitability, and the various direct and indirect expenses
     incurred by the Adviser or its affiliated investment advisers in managing
     the Fund and other funds in the Mellon Institutional Funds family of funds.
     The Independent Trustees had observed that the Adviser, based on the
     profitability information submitted to them by the Adviser, incurred losses
     in managing many of the investment companies in the Mellon Institutional
     Funds family of funds. The Trustees observed that the Adviser had incurred
     gains in operating the Fund in 2005 and 2006.

     Economies of Scale

     The Board also considered the extent to which economies of scale might be
     realized as the Fund grows. They observed that the Standish Mellon Fixed
     Income Fund and The Boston Company International Core Equity Fund, two of
     the largest funds in the complex, already had breakpoints in their fee
     arrangements that reflected economies resulting from their size. The Board
     also noted that at the March 7, 2006 meeting, management had presented a
     Breakpoint Discussion Memorandum that had proposed a framework for future
     breakpoints. The Board concluded that, at existing asset levels and
     considering current asset growth projections, the implementation of
     additional fee breakpoints or other fee reductions was not necessary at
     this time.

                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Other Benefits

     The Board also considered the additional benefits flowing to BNY Mellon as
     a result of its relationship with the Mellon Institutional Funds as a
     group, including revenues received by BNY Mellon affiliates in
     consideration of custodial, administrative, transfer agency and securities
     lending services provided by such affiliates to the Funds. In each case,
     such affiliates were selected by the Board on the basis of a comparative
     analysis of their capabilities and fees relative to those of unaffiliated
     competitors.

     The Board considered the fact that BNY Mellon operates businesses other
     than the Mellon Institutional Funds, some of which businesses share
     personnel, office space and other resources and that these were a component
     of the profitability analysis provided. The Board also considered the
     intangible benefits that accrue to BNY Mellon and its affiliates by virtue
     of its relationship with the Funds and the Mellon Institutional Funds as a
     group.

                                      * * *

     The foregoing factors were among those weighed by the Trustees in
     determining that the terms and conditions of the Fund's advisory agreement
     and the compensation to the Adviser provided therein are fair and
     reasonable and, thus, in approving the continuation of the agreement for a
     one-year period.

                     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 (October 1, 2007 to March 31, 2008).

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 (Unaudited)
- --------------------------------------------------------------------------------

(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 when required for
     federal income tax purposes. Dividend income is recorded on the ex-dividend
     date. Realized gains and losses from securities sold are recorded on the
     identified cost basis. Dividends representing a return of capital are
     reflected as a reduction of cost.

     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 issuers

     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

     In September 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. Management is evaluating the
     implications of FAS 157 and its impact, if any, in the financial statements
     has not yet been determined.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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 six months ended March 31, 2008. Pursuant to this arrangement, for the
     six months ended March 31, 2008, Standish Mellon voluntarily waived a
     portion of its investment advisory fee in the amount of $97,489. 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 $4,826, for the
     six months ended March 31, 2008.

     The Trust has 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 fund accounting
     services for the Fund. For these services the Fund pays Mellon Bank a fixed
     fee plus asset and transaction based fees, as well as out-of-pocket
     expenses. Pursuant to this agreement the Fund was charged $60,739 for the
     six months ended March 31, 2008.

     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
     $869 for the six months ended March 31, 2008, which amount 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 six months ended
     March 31, 2008, the Fund was charged $2,130, 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 Mellon or its affiliates an annual fee and
     a per meeting fee as well as reimbursement for travel and out-of-pocket
     expenses. In addition, the Trust pays the legal fees for the independent
     counsel of the Trustees.

     The 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 $3,800, which amount is included in miscellaneous
     expenses in the Statement of Operations for the six months ended March 31,
     2008.

     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
     six months ended March 31, 2008, the Fund was charged $9,193 for fees
     payable to BNY Mellon Wealth Management.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of Standish Mellon, is the distributor of the Fund's
     shares.

(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 March 31, 2008, two shareholders of record, in the aggregate, held
approximately 64.7% of the total outstanding shares of the Fund. Investment
activities of these shareholders could have a material impact on the Fund. For
example, a significant redemption by such shareholders could result in illiquid
or less liquid investments comprising a larger portion of the Fund's Portfolio.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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 six months ended March 31, 2008, the Fund was
     charged $2,453 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 Internal Revenue 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The tax basis components of distributable earnings and the federal tax cost
     as of March 31, 2008 were as follows:


                                                        
                  Cost for federal income tax purposes     $182,190,782

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


(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. During the six months ended March 31,
     2008, the Fund did not borrow from the line of credit.

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

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. In their
     most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from the Fund's investment adviser, Standish
     Mellon Asset Management Company LLC ("Standish Mellon" or the "Adviser"), a
     broad range of information in response to a written request prepared on
     their behalf by their own legal counsel. The Independent Trustees met alone
     in a private session with their legal counsel on September 27, 2007 to
     review these materials and to discuss the proposed continuation of the
     Fund's advisory agreement. Representatives of management attended a portion
     of the September meeting to provide an overview of the Adviser's
     organization, personnel, resources and strategic plans, and to respond to
     questions and comments arising from the Independent Trustees' review of the
     materials and their deliberations. The entire Board then met on October 30,
     2007.

     The information requested by the Independent Trustees and reviewed by the
     entire Board included:

     (i) Financial and Economic Data: The Adviser's balance sheet and income
     statements, as well as a profitability analysis of the Adviser, including a
     separate presentation of the Adviser's profitability relative to that of
     several publicly traded investment advisers;

     (ii) Management Teams and Operations: The Adviser's Form ADV, as well as
     information concerning the Adviser's executive management, portfolio
     management, client service personnel and overall organizational structure,
     insurance coverage, brokerage and soft dollar policies and practices;

     (iii) Comparative Performance and Fees: Analyses prepared by Lipper
     Analytical Services ("Lipper") regarding the Fund's historical performance,
     management fee and expense ratio compared to other funds, and the Adviser's
     separate account advisory fee schedules;

     (iv) Specific Facts Relating to the Fund: The Adviser's commentary on the
     Fund's performance and any material portfolio manager and strategy changes
     that may have affected the Fund in the prior year, as well as the Fund's
     "fact sheets" prepared by the Adviser providing salient data about the
     Fund, including the Fund's holdings, strategies, recent market conditions
     and outlook, as well as the Adviser's views concerning the issues of
     breakpoints in the management fee schedule of the Fund and potential
     economies of scale; and

     (v) Other Benefits: The benefits flowing to The Bank of New York Mellon
     Corporation ("BNY Mellon") and its affiliates in the form of fees for
     transfer agency, custody, administration and securities lending services
     provided to the Funds by affiliates of BNY Mellon.

     In considering the continuation of the Fund's advisory agreement, the Board
     of Trustees, including the Independent Trustees, did not identify any
     single factor as all-important or controlling, and individual Trustees did
     not necessarily attribute the same weight or importance to each factor. The
     Trustees determined that the terms and conditions of the advisory agreement
     and the compensation to the Adviser provided therein were fair and
     reasonable in light of the services performed, expenses incurred and such
     other matters as the Trustees considered relevant in the exercise of their
     reasonable judgment. The following summary does not detail all the matters
     that were considered. Some of the factors that figured prominently in the
     Trustees' determination are described below.

     Nature, Extent and Quality of Services

     The Board considered the nature, scope and quality of the overall services
     provided to the Fund by the Adviser. In their deliberations as to the
     continuation of the advisory agreement, the Trustees were also mindful of
     the fact that, by choosing to invest in the Fund, the Fund's shareholders
     have chosen to entrust the Adviser, under the supervision of the Board, to
     manage the portion of their assets invested in the Fund.

     Among the specific factors the Board reviewed were the investment
     management, administrative, compliance and related services provided by the
     Adviser. The Board determined that the services provided were of high
     quality and at least commensurate with industry standards.

     The Trustees reviewed the background and experience of the Fund's two
     portfolio managers and also met with senior management of the Adviser to
     receive an overview of its organization, personnel, resources and strategic
     plans. Among other things, the Trustees considered the size, education and
     experience of the Adviser's investment staff, technological infrastructure
     and overall responsiveness to changes in market conditions.

     The Board determined that the Adviser had the expertise and resources to
     manage the Fund effectively.

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

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Investment Performance

     The Board considered the investment performance of the Fund against a peer
     group of investment companies selected by the Adviser with input from the
     Trustees. The Board also compared the Fund's investment performance against
     the average performance of a larger universe of funds regarded by Lipper as
     having similar investment objectives and considered the Fund's performance
     rankings against that universe. In addition to the information received by
     the Board at the September 27, 2007 Board meeting, the Trustees received
     similar detailed comparative performance information for the Fund at each
     regular Board meeting during the year.

     The Board considered the Fund's performance for the one-, three- and
     five-year periods ended July 31, 2007 based on the Lipper materials
     provided to the Board at the September 27, 2007 meeting. The Board found
     that the Fund outperformed its peer group average return for the one-year
     period (3.73% vs. 3.64%), but slightly underperformed its peer group
     average return for the three-year period (3.22% vs. 3.23%) and five-year
     period (3.39% vs. 3.42%).

     Advisory Fee and Other Expenses

     The Board considered the advisory fee rate paid by the Fund to the Adviser.
     The Lipper data presenting the Fund's "net management fees" included fees
     paid by the Fund, as calculated by Lipper, for administrative services
     provided by Mellon Bank, N.A., the Trust's custodian. Such reporting was
     necessary, according to Lipper, to allow the Board to compare the Fund's
     advisory fees to those peers that include administrative fees within a
     blended advisory fee.

     The Fund's contractual advisory fee was 0.40%, which was in the 2nd (1st
     being the best) quintile of its peer group of funds, the median fee of
     which was 0.525%. The Fund's net management fee (after giving effect to
     expense limitations) was 0.231% (which included administrative services
     fees under Lipper's calculation methodology), well below the peer group
     median net management fee of 0.399%. Based on the Lipper data, as well as
     other factors discussed at the September 27, 2007 meeting, the Board
     determined that the Fund's advisory fee is reasonable relative to its peer
     group averages.

     The Board also compared the fees payable by the Fund relative to those
     payable by separate account clients of the Adviser. Based on the additional
     scope and complexity of the services provided and responsibilities assumed
     by the Adviser with respect to the Fund relative to these other types of
     clients, the Board concluded that the fees payable under the advisory
     agreement were reasonable relative to the nature and quality of the
     services provided.

     The Board also considered the Fund's expense ratio and compared it to that
     of its peer group of similar funds. The Board found that the actual net
     expense ratio of 0.45% (after giving effect to expense limitations) was
     lower than the median net expense ratio of the peer group of 0.551%,
     notwithstanding the fact that most of the other funds in the peer group
     were larger than the Fund.

     The Adviser's Profitability

     The Board considered the Adviser's profitability in managing the Fund and
     the Mellon Institutional Funds as a group, as well as the methodology used
     to compute such profitability, and the various direct and indirect expenses
     incurred by the Adviser or its affiliated investment advisers in managing
     the Fund and other funds in the Mellon Institutional Funds family of funds.
     The Independent Trustees had observed that the Adviser, based on the
     profitability information submitted to them by the Adviser, incurred losses
     in managing many of the investment companies in the Mellon Institutional
     Funds family of funds. The Trustees observed that the Adviser had incurred
     losses in operating the Fund in 2005 and 2006.

     Economies of Scale

     The Board also considered the extent to which economies of scale might be
     realized as the Fund grows. They observed that the Standish Mellon Fixed
     Income Fund and The Boston Company International Core Equity Fund, two of
     the largest funds in the complex, already had breakpoints in their fee
     arrangements that reflected economies resulting from their size. The Board
     also noted that at the March 7, 2006 meeting, management had presented a
     Breakpoint Discussion Memorandum that had proposed a framework for future
     breakpoints. The Board concluded that, at existing asset levels and
     considering current asset growth projections, the implementation of
     additional fee breakpoints or other fee reductions was not necessary at
     this time.

              Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Other Benefits

     The Board also considered the additional benefits flowing to BNY Mellon as
     a result of its relationship with the Mellon Institutional Funds as a
     group, including revenues received by BNY Mellon affiliates in
     consideration of custodial, administrative, transfer agency and securities
     lending services provided by such affiliates to the Funds. In each case,
     such affiliates were selected by the Board on the basis of a comparative
     analysis of their capabilities and fees relative to those of unaffiliated
     competitors.

     The Board considered the fact that BNY Mellon operates businesses other
     than the Mellon Institutional Funds, some of which businesses share
     personnel, office space and other resources and that these were a component
     of the profitability analysis provided. The Board also considered the
     intangible benefits that accrue to BNY Mellon and its affiliates by virtue
     of its relationship with the Funds and the Mellon Institutional Funds as a
     group.

     The foregoing factors were among those weighed by the Trustees in
     determining that the terms and conditions of the Fund's advisory agreement
     and the compensation to the Adviser provided therein are fair and
     reasonable and, thus, in approving the continuation of the agreement for a
     one-year period.

general information of the shareholders of the Fund. This report is not
authorized for distribution to prospective investors in the Fund unless preceded

Any information in this shareholder report regarding market or economic trends

                   Mellon Institutional Funds Investment Trust
             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 (October 1, 2007 to March 31, 2008).

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 Paid

  per year before expenses)       $1,000.00          $1,020.40           $4.65


- ---------
+    Expenses are equal to the Fund's annualized expense ratio of 0.92%,
     multiplied by the average account value over the period, multiplied by
     183/366 (to reflect the one-half year period).

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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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.

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

     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

     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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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
     $5,739, for the six months ended March 31, 2008.

     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 fund accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $85,475 for the six months ended March 31,
     2008.

     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 $150,462 for the
     six months ended March 31, 2008. 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
     $426 for the six months ended March 31, 2008, 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 six months ended
     March 31, 2008, the Fund was charged $2,117, 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 $2,885, which amount is included in miscellaneous expenses in the
     Statement of Operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was charged $22,751 for fees
     payable to BNY Mellon Private Wealth Management.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of TBCAM, is the distributor of the Fund's shares.

(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
                                           Six Months Ended         For the

     At March 31, 2008, four shareholders of record, in the aggregate held
     approximately 79.8% of the total outstanding shares of the Fund. Investment
     activities of these shareholders could have a material impact on the Fund.
     For example, a significant redemption by such shareholders could result in
     illiquid or less liquid investments comprising a larger portion of the
     Fund's Portfolio.

     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 six months ended March 31, 2008, 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 Internal Revenue 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, were as follows:


                                                            
                Cost for federal income tax purposes           $361,169,431

                                                               ------------
                Net unrealized appreciation (depreciation)     $  6,618,702
                                                               ============


(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 March 31, 2008, 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.

     Until December 10, 2007, all cash collateral received by the Fund and other
     series of the Trust in connection with the securities lending program was
     invested in the BlackRock Cash Strategies Fund LLC (the "BlackRock Fund"),
     a private investment fund not affiliated with the Trust or its investment
     adviser. On December 10, 2007, the BlackRock Fund announced that it was
     suspending investor withdrawal privileges due to conditions related to the
     credit markets and the adverse affect of such conditions on the liquidity
     of the BlackRock Fund's portfolio holdings. Commencing on December 11,
     2007, all new cash collateral received in connection with the securities
     lending activity of the Fund and other series of the Trust was invested by
     the securities lending agent in the Dreyfus Institutional Cash Advantage
     Fund (the "Dreyfus Fund"), an affiliated money market fund registered as an
     investment company under the Investment Company Act of 1940, as amended. To
     the extent that the BlackRock Fund agreed to permit withdrawals during the
     period December 11, 2007 through March 31, 2008, the securities lending
     agent effected such withdrawals and the cash proceeds from such withdrawals
     by the Fund were reinvested in shares of the Dreyfus Fund. Repayments of
     cash collateral during the period were made from the proceeds of
     redemptions of shares of the Dreyfus Fund. See Schedule of Investments for
     further detail on the Fund's investment of cash collateral in the BlackRock
     Fund and the Dreyfus Fund as of March 31, 2008.

     The Fund loaned securities during the six months ended March 31, 2008 and
     earned interest on the invested collateral of $1,622,024 of which
     $1,270,860 was rebated to borrowers or paid in fees. At March 31, 2008, the
     Fund had securities valued at $70,348,612 on loan of which $72,782,492 was
     collateralized with cash and $178,810 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. During the six months ended March 31, 2008,
     the Fund did not have any borrowings outstanding.

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

     Factors Considered by the Trustees in Approving the Investment Advisory
                              Agreement (Unaudited)
- --------------------------------------------------------------------------------

The 1940 Act requires that the Board of Trustees, including a majority of its
Trustees who are not affiliated with the Fund's investment adviser or
underwriter (the "Independent Trustees") voting separately, approve the Fund's
advisory agreement and the related fees on an annual basis. In their most recent
deliberations concerning their decision to approve the continuation of the
investment advisory agreement, the Board of Trustees conducted the review and
made the determinations that are described below. In conducting this review and
in making such determinations, the Independent Trustees received from the Fund's
investment adviser, The Boston Company Asset Management LLC ("TBCAM" or the
"Adviser"), a broad range of information in response to a written request
prepared on their behalf by their own legal counsel. The Independent Trustees
met alone in a private session with their legal counsel on September 27, 2007 to
review these materials and to discuss the proposed continuation of the Fund's
advisory agreement. Representatives of management attended a portion of the
September meeting to provide an overview of the Adviser's organization,
personnel, resources and strategic plans, and to respond to questions and
comments arising from the Independent Trustees' review of the materials and
their deliberations. The entire Board then met on October 30, 2007.

The information requested by the Independent Trustees and reviewed by the entire
Board included:

(i) Financial and Economic Data: The Adviser's balance sheet and income
statements, as well as a profitability analysis of the Adviser, including a
separate presentation of the Adviser's profitability relative to that of several
publicly traded investment advisers;

(ii) Management Teams and Operations: The Adviser's Form ADV, as well as
information concerning the Adviser's executive management, portfolio management,
client service personnel and overall organizational structure, insurance
coverage, brokerage and soft dollar policies and practices;

(iii) Comparative Performance and Fees: Analyses prepared by Lipper Analytical
Services ("Lipper") regarding the Fund's historical performance, management fee
and expense ratio compared to other funds, and the Adviser's separate account
advisory fee schedules;

(iv) Specific Facts Relating to the Fund: The Adviser's commentary on the Fund's
performance and any material portfolio manager and strategy changes that may
have affected the Fund in the prior year, as well as the Fund's "fact sheets"
prepared by the Adviser providing salient data about the Fund, including the
Fund's holdings, strategies, recent market conditions and outlook, as well as
the Adviser's views concerning the issues of breakpoints in the management fee
schedule of the Fund and potential economies of scale; and

(v) Other Benefits: The benefits flowing to The Bank of New York Mellon
Corporation ("BNY Mellon") and its affiliates in the form of fees for transfer
agency, custody, administration and securities lending services provided to the
Funds by affiliates of BNY Mellon.

In considering the continuation of the Fund's advisory agreement, the Board of
Trustees, including the Independent Trustees, did not identify any single factor
as all-important or controlling, and individual Trustees did not necessarily
attribute the same weight or importance to each factor. The Trustees determined
that the terms and conditions of the advisory agreement and the compensation to
the Adviser provided therein were fair and reasonable in light of the services
performed, expenses incurred and such other matters as the Trustees considered
relevant in the exercise of their reasonable judgment. The following summary
does not detail all the matters that were considered. Some of the factors that
figured prominently in the Trustees' determination are described below.

Nature, Extent and Quality of Services

The Board considered the nature, scope and quality of the overall services
provided to the Fund by the Adviser. In their deliberations as to the
continuation of the advisory agreement, the Trustees were also mindful of the
fact that, by choosing to invest in the Fund, the Fund's shareholders have
chosen to entrust the Adviser, under the supervision of the Board, to manage the
portion of their assets invested in the Fund.

Among the specific factors the Board reviewed were the investment management,
administrative, compliance and related services provided by the Adviser. The
Board determined that the services provided were of high quality and at least
commensurate with industry standards.

The Trustees reviewed the background and experience of the Fund's two portfolio
managers and also met with senior management of the Adviser to receive an
overview of its organization, personnel, resources and strategic plans. Among
other things, the Trustees considered the size, education and experience of the
Adviser's investment staff, technological infrastructure and overall
responsiveness to changes in market conditions.

The Board determined that the Adviser had the expertise and resources to manage
the Fund effectively.

    Factors Considered by the Trustees in Approving the Investment Advisory
                             Agreement (Unaudited)
- --------------------------------------------------------------------------------

Investment Performance

The Board considered the investment performance of the Fund against a peer group
of investment companies selected by the Adviser with input from the Trustees.
The Board also compared the Fund's investment performance against the average
performance of a larger universe of funds regarded by Lipper as having similar
investment objectives and considered the Fund's performance rankings against
that universe. In addition to the information received by the Board at the
September 27, 2007 Board meeting, the Trustees received similar detailed
comparative performance information for the Fund at each regular Board meeting
during the year.

The Board considered the Fund's performance for the one-, three- and five-year
periods ended July 31, 2007 based on the Lipper materials provided to the Board
at the September 27, 2007 meeting. The Board found that the Fund underperformed
its peer group average return for the one-year period (18.50% vs. 18.60%) and
three-year period (14.77% vs. 14.81%), and outperformed its peer group average
return for the five-year period (16.99% vs. 16.89%).

Advisory Fee and Other Expenses

The Board considered the advisory fee rate paid by the Fund to the Adviser. The
Lipper data presenting the Fund's "net management fees" included fees paid by
the Fund, as calculated by Lipper, for administrative services provided by
Mellon Bank, N.A., the Trust's custodian. Such reporting was necessary,
according to Lipper, to allow the Board to compare the Fund's advisory fees to
those peers that include administrative fees within a blended advisory fee.

The Fund's contractual advisory fee was 0.80%, which was in the 2nd (1st being
the best) quintile of its peer group of funds, the median fee of which was
0.85%. The Fund's net management fee was 0.808% (which included administrative
services fees under Lipper's calculation methodology), below the peer group
median net management fee of 0.850%. Based on the Lipper data, as well as other
factors discussed at the September 27, 2007 meeting, the Board determined that
the Fund's advisory fee is reasonable relative to its peer group averages.

The Board also compared the fees payable by the Fund relative to those payable
by separate account clients of the Adviser. Based on the additional scope and
complexity of the services provided and responsibilities assumed by the Adviser
with respect to the Fund relative to these other types of clients, the Board
concluded that the fees payable under the advisory agreement were reasonable
relative to the nature and quality of the services provided.

The Board also considered the Fund's expense ratio and compared it to that of
its peer group of similar funds. The Board found that the actual net expense
ratio of 0.992% was lower than the median net expense ratio of the peer group of
1.105%, notwithstanding the fact that most of the other funds in the peer group
were larger than the Fund.

The Adviser's Profitability

The Board considered the Adviser's profitability in managing the Fund and the
Mellon Institutional Funds as a group, as well as the methodology used to
compute such profitability, and the various direct and indirect expenses
incurred by the Adviser or its affiliated investment advisers in managing the
Fund and other funds in the Mellon Institutional Funds family of funds. The
Independent Trustees had observed that the Adviser, based on the profitability
information submitted to them by the Adviser, incurred losses in managing many
of the investment companies in the Mellon Institutional Funds family of funds.
The Trustees observed that the Adviser had incurred gains in operating the Fund
in 2005 and 2006.

Economies of Scale

The Board also considered the extent to which economies of scale might be
realized as the Fund grows. They observed that the Standish Mellon Fixed Income
Fund and The Boston Company International Core Equity Fund, two of the largest
funds in the complex, already had breakpoints in their fee arrangements that
reflected economies resulting from their size. The Board also noted that at the
March 7, 2006 meeting, management had presented a Breakpoint Discussion
Memorandum that had proposed a framework for future breakpoints. The Board
concluded that, at existing asset levels and considering current asset growth
projections, the implementation of additional fee breakpoints or other fee
reductions was not necessary at this time.

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

Other Benefits

The Board also considered the additional benefits flowing to BNY Mellon as a
result of its relationship with the Mellon Institutional Funds as a group,
including revenues received by BNY Mellon affiliates in consideration of
custodial, administrative, transfer agency and securities lending services
provided by such affiliates to the Funds. In each case, such affiliates were
selected by the Board on the basis of a comparative analysis of their
capabilities and fees relative to those of unaffiliated competitors.

The Board considered the fact that BNY Mellon operates businesses other than the
Mellon Institutional Funds, some of which businesses share personnel, office
space and other resources and that these were a component of the profitability
analysis provided. The Board also considered the intangible benefits that accrue
to BNY Mellon and its affiliates by virtue of its relationship with the Funds
and the Mellon Institutional Funds as a group.

                                      * * *

The foregoing factors were among those weighed by the Trustees in determining
that the terms and conditions of the Fund's advisory agreement and the
compensation to the Adviser provided therein are fair and reasonable and, thus,
in approving the continuation of the agreement for a one-year period.

This report and the financial statements contained herein are submitted for the
general information of the shareholders of the Fund. This report is not
authorized for distribution to prospective investors in the Fund unless preceded

Any information in this shareholder report regarding market or economic trends

                   Mellon Institutional Funds Investment Trust
                The Boston Company International Small Cap 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 (October 1, 2007 to March 31, 2008).

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 Paid

- -------
+    Expenses are equal to the Fund's annualized expense ratio of 1.21%,
     multiplied by the average account value over the period, multiplied by
     183/366 (to reflect the one-half year period).

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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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.

     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.

     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.

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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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 (the "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

     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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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 1.00% of the Fund's average daily net assets.

     For the period of October 1, 2007 through August 31, 2008, TBCAM has agreed
     to rebate 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 six months ended March 31, 2008, TBCAM rebated
     $270,268 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
     $10,725, for the six months ended March 31, 2008.

     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 fund accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $247,906 for the six months ended March 31,
     2008.

     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 $0 for the six
     months ended March 31, 2008. See Note 7 for further details.

     The 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
     $65,153 for the six months ended March 31, 2008, which is included in
     miscellaneous expenses in the Statement of Operations. See Note 9 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 six months ended
     March 31, 2008, the Fund was charged $2,144, 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 $12,732, which amount is included in miscellaneous expenses in the
     Statement of Operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was charged $32,350 for fees
     payable to BNY Mellon Wealth Management.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of TBCAM, is the distributor of the Fund's shares.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the six months ended March 31, 2008 were as follows:

(4)  Shares of Beneficial Interest:

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

     At March 31, 2008, two shareholders of record, in the aggregate held
     approximately 43.1% of the total outstanding shares of the Fund. Investment
     activities of these shareholders could have a material impact on the Fund.
     For example, a significant redemption by such shareholders could result in
     illiquid or less liquid investments comprising a larger portion of the
     Fund's Portfolio.

     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 six months ended March 31, 2008, the Fund received
     $4,825 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

(6)  Financial Instruments:

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

     The 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.

     For the six months ended March 31, 2008, the Fund held open financial
     futures contracts. See the Schedule of Investments for further details.

     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.

     For the six months ended March 31, 2008, the Fund held forward foreign
     currency exchange 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 did not loan securities during the six months ended March 31,
     2008.

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

(8)  Delayed Delivery Transactions:

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

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

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

     At March 31, 2008, the Fund held delayed delivery securities. See the
     Schedule of Investments for further details.

(9)  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 six months ended March 31, 2008, the
     Fund had average borrowings outstanding of $8,331,365 for a total of 52
     days and incurred interest expense of $58,632. At March 31, 2008, the Fund
     did not have a loan balance outstanding.

(10) Reverse Share Split:

     On December 20, 2007, the Trustees of the Fund approved a 1:10 reverse
     share split for the Fund which was effective as of January 24, 2008. The
     purpose of the reverse share split was to increase the Fund's net asset
     value per share back in line with similarly managed funds. The Fund's net
     asset value per share had been reduced on December 17, 2007 as a result of
     a large capital gain distribution paid to those Fund shareholders of record
     as of December 13, 2007. Each shareholder may determine the number of
     shares it owns as a result of the reverse share split by dividing the
     number of shares owned immediately prior to the reverse share split by ten.
     The reverse share split has not resulted in a change to shareholder account
     balances.

     The Financial Highlights have been restated to reflect the reverse share
     split.

                The Boston Company International Small Cap Fund

     Factors Considered by the Trustees in Approving the Investment Advisory
                              Agreement (Unaudited)
- --------------------------------------------------------------------------------

The 1940 Act requires that the Board of Trustees, including a majority of its
Trustees who are not affiliated with the Fund's investment adviser or
underwriter (the "Independent Trustees") voting separately, approve the Fund's
advisory agreement and the related fees on an annual basis. In their most recent
deliberations concerning their decision to approve the continuation of the
investment advisory agreement, the Board of Trustees conducted the review and
made the determinations that are described below. In conducting this review and
in making such determinations, the Independent Trustees received from the Fund's
investment adviser, The Boston Company Asset Management LLC ("TBCAM" or the
"Adviser"), a broad range of information in response to a written request
prepared on their behalf by their own legal counsel. The Independent Trustees
met alone in a private session with their legal counsel on September 27, 2007 to
review these materials and to discuss the proposed continuation of the Fund's
advisory agreement. Representatives of management attended a portion of the
September meeting to provide an overview of the Adviser's organization,
personnel, resources and strategic plans, and to respond to questions and
comments arising from the Independent Trustees' review of the materials and
their deliberations. The entire Board then met on October 30, 2007.

The information requested by the Independent Trustees and reviewed by the entire
Board included:

(i) Financial and Economic Data: The Adviser's balance sheet and income
statements, as well as a profitability analysis of the Adviser, including a
separate presentation of the Adviser's profitability relative to that of several
publicly traded investment advisers;

(ii) Management Teams and Operations: The Adviser's Form ADV, as well as
information concerning the Adviser's executive management, portfolio management,
client service personnel and overall organizational structure, insurance
coverage, brokerage and soft dollar policies and practices;

(iii) Comparative Performance and Fees: Analyses prepared by Lipper Analytical
Services ("Lipper") regarding the Fund's historical performance, management fee
and expense ratio compared to other funds, and the Adviser's separate account
advisory fee schedules;

(iv) Specific Facts Relating to the Fund: The Adviser's commentary on the Fund's
performance and any material portfolio manager and strategy changes that may
have affected the Fund in the prior year, as well as the Fund's "fact sheets"
prepared by the Adviser providing salient data about the Fund, including the
Fund's holdings, strategies, recent market conditions and outlook, as well as
the Adviser's views concerning the issues of breakpoints in the management fee
schedule of the Fund and potential economies of scale; and

(v) Other Benefits: The benefits flowing to The Bank of New York Mellon
Corporation ("BNY Mellon") and its affiliates in the form of fees for transfer
agency, custody, administration and securities lending services provided to the
Funds by affiliates of BNY Mellon.

In considering the continuation of the Fund's advisory agreement, the Board of
Trustees, including the Independent Trustees, did not identify any single factor
as all-important or controlling, and individual Trustees did not necessarily
attribute the same weight or importance to each factor. The Trustees determined
that the terms and conditions of the advisory agreement and the compensation to
the Adviser provided therein were fair and reasonable in light of the services
performed, expenses incurred and such other matters as the Trustees considered
relevant in the exercise of their reasonable judgment. The following summary
does not detail all the matters that were considered. Some of the factors that
figured prominently in the Trustees' determination are described below.

Nature, Extent and Quality of Services

The Board considered the nature, scope and quality of the overall services
provided to the Fund by the Adviser. In their deliberations as to the
continuation of the advisory agreement, the Trustees were also mindful of the
fact that, by choosing to invest in the Fund, the Fund's shareholders have
chosen to entrust the Adviser, under the supervision of the Board, to manage the
portion of their assets invested in the Fund.

Among the specific factors the Board reviewed were the investment management,
administrative, compliance and related services provided by the Adviser. The
Board determined that the services provided were of high quality and at least
commensurate with industry standards.

The Trustees reviewed the background and experience of the Fund's portfolio
manager and also met with senior management of the Adviser to receive an
overview of its organization, personnel, resources and strategic plans. Among
other things, the Trustees considered the size, education and experience of the
Adviser's investment staff, technological infrastructure and overall
responsiveness to changes in market conditions.

The Board determined that the Adviser had the expertise and resources to manage
the Fund effectively.

Investment Performance

The Board considered the investment performance of the Fund against a peer group
of investment companies selected by the Adviser with input from the Trustees.
The Board also compared the Fund's investment performance against the average
performance of a larger universe of funds regarded by Lipper as having similar
investment objectives and considered the Fund's performance rankings against
that universe. In addition to the information received by the Board at the
September 27, 2007 Board meeting, the Trustees received similar detailed
comparative performance information for the Fund at each regular Board meeting
during the year.

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

    Factors Considered by the Trustees in Approving the Investment Advisory
                             Agreement (Unaudited)
- --------------------------------------------------------------------------------

The Board considered the Fund's performance for the one-, three- and five-year
periods ended July 31, 2007 based on the Lipper materials provided to the Board
at the September 27, 2007 meeting. The Board found that the Fund underperformed
its peer group average return for the one-year period (28.92% vs. 34.35%), and
outperformed its peer group average return for the three-year period (31.71% vs.
29.69%) and five-year period (29.69% vs. 27.15%).

Advisory Fee and Other Expenses

The Board considered the advisory fee rate paid by the Fund to the Adviser. The
Lipper data presenting the Fund's "net management fees" included fees paid by
the Fund, as calculated by Lipper, for administrative services provided by
Mellon Bank, N.A., the Trust's custodian. Such reporting was necessary,
according to Lipper, to allow the Board to compare the Fund's advisory fees to
those peers that include administrative fees within a blended advisory fee.

The Fund's contractual advisory fee was 1.00%, which was in the 3rd (1st being
the best) quintile of its peer group of funds, the median fee of which was
0.978%. The Fund's net management fee (after giving effect to expense
limitations) was 0.999% (which included no administrative services fees under
Lipper's calculation methodology), above the peer group median net management
fee of 0.931%. Based on the Lipper data, as well as other factors discussed at
the September 27, 2007 meeting, the Board determined that the Fund's advisory
fee is reasonable relative to its peer group averages.

The Board also compared the fees payable by the Fund relative to those payable
by separate account clients of the Adviser. Based on the additional scope and
complexity of the services provided and responsibilities assumed by the Adviser
with respect to the Fund relative to these other types of clients, the Board
concluded that the fees payable under the advisory agreement were reasonable
relative to the nature and quality of the services provided.

The Board also considered the Fund's expense ratio and compared it to that of
its peer group of similar funds. The Board found that the actual net expense
ratio of 1.114% was lower than the median net expense ratio of the peer group of
1.23%, notwithstanding the fact that all of the other funds in the peer group
were larger than the Fund.

The Adviser's Profitability

The Board considered the Adviser's profitability in managing the Fund and the
Mellon Institutional Funds as a group, as well as the methodology used to
compute such profitability, and the various direct and indirect expenses
incurred by the Adviser or its affiliated investment advisers in managing the
Fund and other funds in the Mellon Institutional Funds family of funds. The
Independent Trustees had observed that the Adviser, based on the profitability
information submitted to them by the Adviser, incurred losses in managing many
of the investment companies in the Mellon Institutional Funds family of funds.
The Trustees observed that the Adviser had incurred gains in operating the Fund
in 2005 and 2006.

Economies of Scale

The Board also considered the extent to which economies of scale might be
realized as the Fund grows. They observed that the Standish Mellon Fixed Income
Fund and The Boston Company International Core Equity Fund, two of the largest
funds in the complex, already had breakpoints in their fee arrangements that
reflected economies resulting from their size. The Board also noted that at the
March 7, 2006 meeting, management had presented a Breakpoint Discussion
Memorandum that had proposed a framework for future breakpoints. The Board
concluded that, at existing asset levels and considering current asset growth
projections, the implementation of additional fee breakpoints or other fee
reductions was not necessary at this time.

Other Benefits

The Board also considered the additional benefits flowing to BNY Mellon as a
result of its relationship with the Mellon Institutional Funds as a group,
including revenues received by BNY Mellon affiliates in consideration of
custodial, administrative, transfer agency and securities lending services
provided by such affiliates to the Funds. In each case, such affiliates were
selected by the Board on the basis of a comparative analysis of their
capabilities and fees relative to those of unaffiliated competitors.

The Board considered the fact that BNY Mellon operates businesses other than the
Mellon Institutional Funds, some of which businesses share personnel, office
space and other resources and that these were a component of the profitability
analysis provided. The Board also considered the intangible benefits that accrue
to BNY Mellon and its affiliates by virtue of its relationship with the Funds
and the Mellon Institutional Funds as a group.

                                      * * *

The foregoing factors were among those weighed by the Trustees in determining
that the terms and conditions of the Fund's advisory agreement and the
compensation to the Adviser provided therein are fair and reasonable and, thus,
in approving the continuation of the agreement for a one-year period.

general information of the shareholders of the Fund. This report is not
authorized for distribution to prospective investors in the Fund unless preceded

Any information in this shareholder report regarding market or economic trends

statements of the opinion of Fund management as of the date of this report.
These statements should not be relied upon for any other purposes. Past

                     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 (October 1, 2007 to March 31, 2008).

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 Paid

  per year before expenses)        $1,000.00           $1,020.15             $4.90


- ----------

+    Expenses are equal to the Fund's annualized expense ratio of 0.97%,
     multiplied by the average account value over the period, multiplied by
     183/366 (to reflect the one-half year period).

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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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 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.

     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.

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


     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

     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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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 0.80% 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
     $4,767, for the six months ended March 31, 2008.

     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 fund accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $68,384 for the six months ended March 31,
     2008.

     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 $94,810 for the
     six months ended March 31, 2008. 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
     $130 for the six months ended March 31, 2008, which amount is included in
     miscellaneous expenses on the Statement of Operations. See Note 8 for
     further details.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the six months ended
     March 31, 2008, the Fund was charged $2,130, 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 $1,223, which amount is included in miscellaneous expenses in the
     Statement of Operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was charged $6,336 for fees
     payable to BNY Mellon Private Wealth Management.

     activities of these shareholders could have a material impact on the Fund.
     For example, a significant redemption by such shareholders could result in
     illiquid or less liquid investments comprising a larger portion of the
     Fund's Portfolio.

     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 six months ended March 31, 2008, the Fund received
     $8,219 in redemption fees which are 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 Internal Revenue 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.

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

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 208, as computed on a federal
     income tax basis, 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 March 31, 2008, 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.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     Until December 10, 2007, all cash collateral received by the Fund and other
     series of the Trust in connection with the securities lending program was
     invested in the BlackRock Cash Strategies Fund LLC (the "BlackRock Fund"),
     a private investment fund not affiliated with the Trust or its investment
     adviser. On December 10, 2007, the BlackRock Fund announced that it was
     suspending investor withdrawal privileges due to conditions related to the
     credit markets and the adverse affect of such conditions on the liquidity
     of the BlackRock Fund's portfolio holdings. Commencing on December 11,
     2007, all new cash collateral received in connection with the securities
     lending activity of the Fund and other series of the Trust was invested by
     the securities lending agent in the Dreyfus Institutional Cash Advantage
     Fund (the "Dreyfus Fund"), an affiliated money market fund registered as an
     investment company under the Investment Company Act of 1940, as amended. To
     the extent that the BlackRock Fund agreed to permit withdrawals during the
     period December 11, 2007 through March 31, 2008, the securities lending
     agent effected such withdrawals and the cash proceeds from such withdrawals
     by the Fund were reinvested in shares of the Dreyfus Fund. Repayments of
     cash collateral during the period were made from the proceeds of
     redemptions of shares of the Dreyfus Fund. See Schedule of Investments for
     further detail on the Fund's investment of cash collateral in the BlackRock
     Fund and the Dreyfus Fund as of March 31, 2008.

     The Fund loaned securities during the six months ended March 31, 2008 and
     earned interest on the invested collateral of $913,154 of which $604,287
     was rebated to borrowers or paid in fees. 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 six months ended March 31, 2008, the
     Fund did not borrow from the line of credit.

                Factors Considered by the Trustees in Approving
                  the Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. In their
     most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from the Fund's investment adviser, The
     Boston Company Asset Management LLC ("TBCAM" or the "Adviser"), a broad
     range of information in response to a written request prepared on their
     behalf by their own legal counsel. The Independent Trustees met alone in a
     private session with their legal counsel on September 27, 2007 to review
     these materials and to discuss the proposed continuation of the Fund's
     advisory agreement. Representatives of management attended a portion of the
     September meeting to provide an overview of the Adviser's organization,
     personnel, resources and strategic plans, and to respond to questions and
     comments arising from the Independent Trustees' review of the materials and
     their deliberations. The entire Board then met on October 30, 2007.

     The information requested by the Independent Trustees and reviewed by the
     entire Board included:

     (i) Financial and Economic Data: The Adviser's balance sheet and income
     statements, as well as a profitability analysis of the Adviser, including a
     separate presentation of the Adviser's profitability relative to that of
     several publicly traded investment advisers;

     (ii) Management Teams and Operations: The Adviser's Form ADV, as well as
     information concerning the Adviser's executive management, portfolio
     management, client service personnel and overall organizational structure,
     insurance coverage, brokerage and soft dollar policies and practices;

     (iii) Comparative Performance and Fees: Analyses prepared by Lipper
     Analytical Services ("Lipper") regarding the Fund's historical performance,
     management fee and expense ratio compared to other funds, and the Adviser's
     separate account advisory fee schedules;

     (iv) Specific Facts Relating to the Fund: The Adviser's commentary on the
     Fund's performance and any material portfolio manager and strategy changes
     that may have affected the Fund in the prior year, as well as the Fund's
     "fact sheets" prepared by the Adviser providing salient data about the
     Fund, including the Fund's holdings, strategies, recent market conditions
     and outlook, as well as the Adviser's views concerning the issues of
     breakpoints in the management fee schedule of the Fund and potential
     economies of scale; and

     (v) Other Benefits: The benefits flowing to The Bank of New York Mellon
     Corporation ("BNY Mellon") and its affiliates in the form of fees for
     transfer agency, custody, administration and securities lending services
     provided to the Funds by affiliates of BNY Mellon.

     In considering the continuation of the Fund's advisory agreement, the Board
     of Trustees, including the Independent Trustees, did not identify any
     single factor as all-important or controlling, and individual Trustees did
     not necessarily attribute the same weight or importance to each factor. The
     Trustees determined that the terms and conditions of the advisory agreement
     and the compensation to the Adviser provided therein were fair and
     reasonable in light of the services performed, expenses incurred and such
     other matters as the Trustees considered relevant in the exercise of their
     reasonable judgment. The following summary does not detail all the matters
     that were considered. Some of the factors that figured prominently in the
     Trustees' determination are described below.

     Nature, Extent and Quality of Services

     The Board considered the nature, scope and quality of the overall services
     provided to the Fund by the Adviser. In their deliberations as to the
     continuation of the advisory agreement, the Trustees were also mindful of
     the fact that, by choosing to invest in the Fund, the Fund's shareholders
     have chosen to entrust the Adviser, under the supervision of the Board, to
     manage the portion of their assets invested in the Fund.

     Among the specific factors the Board reviewed were the investment
     management, administrative, compliance and related services provided by the
     Adviser. The Board determined that the services provided were of high
     quality and at least commensurate with industry standards.

     The Trustees reviewed the background and experience of the Fund's two
     portfolio managers and also met with senior management of the Adviser to
     receive an overview of its organization, personnel, resources and strategic
     plans. Among other things, the Trustees considered the size, education and
     experience of the Adviser's investment staff, technological infrastructure
     and overall responsiveness to changes in market conditions.

     The Board determined that the Adviser had the expertise and resources to
     manage the Fund effectively.

                Factors Considered by the Trustees in Approving
                  the Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Investment Performance

     The Board considered the investment performance of the Fund against a peer
     group of investment companies selected by the Adviser with input from the
     Trustees. The Board also compared the Fund's investment performance against
     the average performance of a larger universe of funds regarded by Lipper as
     having similar investment objectives and considered the Fund's performance
     rankings against that universe. In addition to the information received by
     the Board at the September 27, 2007 Board meeting, the Trustees received
     similar detailed comparative performance information for the Fund at each
     regular Board meeting during the year.

     The Board considered the Fund's performance for the one-, three- and
     five-year periods ended July 31, 2007 based on the Lipper materials
     provided to the Board at the September 27, 2007 meeting. The Board found
     that the Fund underperformed its peer group average return for the one-year
     period (17.26% vs. 19.11%), three-year period (14.31% vs. 14.73%) and
     five-year period (16.40% vs. 16.86%).

     Advisory Fee and Other Expenses

     The Board considered the advisory fee rate paid by the Fund to the Adviser.
     The Lipper data presenting the Fund's "net management fees" included fees
     paid by the Fund, as calculated by Lipper, for administrative services
     provided by Mellon Bank, N.A., the Trust's custodian. Such reporting was
     necessary, according to Lipper, to allow the Board to compare the Fund's
     advisory fees to those peers that include administrative fees within a
     blended advisory fee.

     The Fund's contractual advisory fee was 0.80%, which was in the 2nd (1st
     being the best) quintile of its peer group of funds, the median fee of
     which was 0.90%. The Fund's net management fee (after giving effect to
     expense reimbursements) was 0.557% (which included administrative services
     fees under Lipper's calculation methodology), well below the peer group
     median net management fee of 0.85%. Based on the Lipper data, as well as
     other factors discussed at the September 27, 2007 meeting, the Board
     determined that the Fund's advisory fee is reasonable relative to its peer
     group averages.

     The Board also compared the fees payable by the Fund relative to those
     payable by separate account clients of the Adviser. Based on the additional
     scope and complexity of the services provided and responsibilities assumed
     by the Adviser with respect to the Fund relative to these other types of
     clients, the Board concluded that the fees payable under the advisory
     agreement were reasonable relative to the nature and quality of the
     services provided.

     The Board also considered the Fund's expense ratio and compared it to that
     of its peer group of similar funds. The Board found that the actual net
     expense ratio of 1.10% (after giving effect to expense reimbursements) was
     the same as the median net expense ratio of the peer group of 1.10%,
     notwithstanding the fact that all of the other funds in the peer group were
     larger than the Fund.

     The Adviser's Profitability

     The Board considered the Adviser's profitability in managing the Fund and
     the Mellon Institutional Funds as a group, as well as the methodology used
     to compute such profitability, and the various direct and indirect expenses
     incurred by the Adviser or its affiliated investment advisers in managing
     the Fund and other funds in the Mellon Institutional Funds family of funds.
     The Independent Trustees had observed that the Adviser, based on the
     profitability information submitted to them by the Adviser, incurred losses
     in managing many of the investment companies in the Mellon Institutional
     Funds family of funds. The Trustees observed that the Adviser had incurred
     losses in operating the Fund in 2005 and 2006.

     Economies of Scale

     The Board also considered the extent to which economies of scale might be
     realized as the Fund grows. They observed that the Standish Mellon Fixed
     Income Fund and The Boston Company International Core Equity Fund, two of
     the largest funds in the complex, already had breakpoints in their fee
     arrangements that reflected economies resulting from their size. The Board
     also noted that at the March 7, 2006 meeting, management had presented a
     Breakpoint Discussion Memorandum that had proposed a framework for future
     breakpoints. The Board concluded that, at existing asset levels and
     considering current asset growth projections, the implementation of
     additional fee breakpoints or other fee reductions was not necessary at
     this time.

                  the Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

     Other Benefits

     The Board also considered the additional benefits flowing to BNY Mellon as
     a result of its relationship with the Mellon Institutional Funds as a
     group, including revenues received by BNY Mellon affiliates in
     consideration of custodial, administrative, transfer agency and securities
     lending services provided by such affiliates to the Funds. In each case,
     such affiliates were selected by the Board on the basis of a comparative
     analysis of their capabilities and fees relative to those of unaffiliated
     competitors.

     The Board considered the fact that BNY Mellon operates businesses other
     than the Mellon Institutional Funds, some of which businesses share
     personnel, office space and other resources and that these were a component
     of the profitability analysis provided. The Board also considered the
     intangible benefits that accrue to BNY Mellon and its affiliates by virtue
     of its relationship with the Funds and the Mellon Institutional Funds as a
     group.

                                      * * *

     The foregoing factors were among those weighed by the Trustees in
     determining that the terms and conditions of the Fund's advisory agreement
     and the compensation to the Adviser provided therein are fair and
     reasonable and, thus, in approving the continuation of the agreement for a
     one-year period.

March 31, 2008 (Unaudited)

                   The Boston Company Small Cap Value Fund II

                     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 (October 1, 2007 to March 31, 2008).

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 Paid

Hypothetical (5% return
  per year before expenses)       $1,000.00         $1,020.00             $5.05


- ----------
+    Expenses are equal to the Fund's annualized expense ratio of 1.00%,
     multiplied by the average account value over the period, multiplied by
     183/366 (to reflect the one-half year period).

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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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 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 Fund 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.
     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.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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

     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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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 six months ended March
     31, 2008, TBCAM voluntarily waived its investment advisory fee in the
     amount of $21,240 and reimbursed the Fund for $31,378 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
     $2,747, for the six months ended March 31, 2008.

     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 $26,944 for the six months ended March 31,
     2008.

     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 $1,916 for the six
     months ended March 31, 2008. See Note 7 for further details.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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 $8
     for the six months ended March 31, 2008, 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 six months ended
     March 31, 2008, the Fund was charged $2,247, 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 $500, which amount is included in miscellaneous expenses in the
     Statement of Operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was not charged an administrative
     service fee by an affiliate of BNY Mellon.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of TBCAM, is the distributor of the Fund's shares.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the six months ended March 31, 2008 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
                                             For the           July 23, 2007

     At March 31, 2008, three shareholders of record, in the aggregate held
     approximately 75.9% of the total outstanding shares of the Fund. Investment
     activities of these shareholders could have a material impact on the Fund.
     For example, a significant redemption by such shareholders could result in
     illiquid or less liquid investments comprising a large portion of the
     Fund's Portfolio.

                                       15


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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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 six months ended March 31, 2008, 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 Internal Revenue 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, were as follows:


                                                     
         Cost for federal income tax purposes           $7,423,841
                                                        ==========
         Gross unrealized appreciation                  $  160,454
         Gross unrealized depreciation                    (791,439)
                                                        ----------
         Net unrealized appreciation (depreciation)     $ (630,985)
                                                        ==========


(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.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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 March 31, 2008, the Fund did not have any open financial futures
     contracts.

(7)  Security Lending:

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

     Until December 10, 2007, all cash collateral received by the Fund and other
     series of the Trust in connection with the securities lending program was
     invested in the BlackRock Cash Strategies Fund LLC (the "BlackRock Fund"),
     a private investment fund not affiliated with the Trust or its investment
     adviser. On December 10, 2007, the BlackRock Fund announced that it was
     suspending investor withdrawal privileges due to conditions related to the
     credit markets and the adverse affect of such conditions on the liquidity
     of the BlackRock Fund's portfolio holdings. Commencing on December 11,
     2007, all new cash collateral received in connection with the securities
     lending activity of the Fund and other series of the Trust was invested by
     the securities lending agent in the Dreyfus Institutional Cash Advantage
     Fund (the "Dreyfus Fund"), an affiliated money market fund registered as an
     investment company under the Investment Company Act of 1940, as amended. To
     the extent that the BlackRock Fund agreed to permit withdrawals during the
     period December 11, 2007 through March 31, 2008, the securities lending
     agent effected such withdrawals and the cash proceeds from such withdrawals
     by the Fund were reinvested in shares of the Dreyfus Fund. Repayments of
     cash collateral during the period were made from the proceeds of
     redemptions of shares of the Dreyfus Fund. See Schedule of Investments for
     further detail on the Fund's investment of cash collateral in the BlackRock
     Fund and the Dreyfus Fund as of March 31, 2008.

     The Fund loaned securities during the six months ended March 31, 2008 and
     earned interest on the invested collateral of $9,645 of which $5,387 was
     rebated to borrowers or paid in fees. 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. During the six months ended March 31, 2008,
     the Fund did not borrow from the line of credit.

                   The Boston Company Small Cap Value Fund II

               Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

The 1940 Act requires that the Board of Trustees, including a majority of its
Trustees who are not affiliated with the Fund's investment adviser or
underwriter (the "Independent Trustees") voting separately, approve the Fund's
advisory agreement and related fees initially and, after a two year initial
term, on an annual basis. At a meeting held on June 22, 2007, the Board of
Trustees, including all of the Independent Trustees voting separately in person,
determined that the terms of the Fund's proposed investment advisory agreement
were fair and reasonable and that the agreement is in the best interest of the
Fund.

The Independent Trustees considered the initial approval of the advisory
agreement of the Fund in connection with their broader consideration of the
annual renewal of the advisory agreements of the other funds of the Trust, in
two separate meetings held on September 28 and October 17, 2006. On each date,
the Independent Trustees held executive sessions in which they met privately
without representatives of The Boston Company Asset Management LLC ("TBCAM" or
the "Adviser"), the Fund's investment adviser, or Mellon Financial Corporation
("Mellon") present and were advised throughout the process by their own legal
counsel.

In conducting this review and in making their determinations, the Independent
Trustees received from TBCAM a broad range of information compiled using an
information request list prepared on their behalf by their own legal counsel in
connection with their annual approval of advisory arrangements with respect to
the funds comprising the Trust generally.

This information included information about TBCAM, its personnel, operations and
financial results and information about the Mellon organization. The Trustees
also discussed in person with representatives of TBCAM the adviser's investment
strategy and process, and the Fund's proposed operations under TBCAM's
management. The information requested by the Independent Trustees and reviewed
by the entire Board included:

(i) Financial and Economic Data: TBCAM's balance sheet and income statement, as
well as a profitability analysis of the Adviser, including a separate
presentation of the TBCAM's profitability relative to that of several publicly
traded investment advisers;

(ii) Management Teams and Operations: TBCAM's Form ADV, as well as information
concerning its executive management and portfolio management personnel and
overall organizational structure, brokerage and soft dollar policies and
practices; and

(iii) Comparative Performance and Fees: Analyses regarding the historical
performance of similarly managed accounts of TBCAM, as well as the Fund's
proposed management fee and estimated expense ratio compared to those of
comparable funds and TBCAM's separate account advisory fee schedules for
comparable TBCAM accounts.

The Independent Trustees had previously been supplied with materials in
connection with the annual approval of the advisory agreements of other funds
within the Trust concerning the benefits flowing to Mellon and its affiliates in
the form of fees for transfer agency, custody, administration and securities
lending services provided to the funds within the Trust by affiliates of Mellon.

In considering the approval of the Fund's advisory agreement, the Board of
Trustees, including the Independent Trustees, did not identify any single factor
as all-important or controlling and individual Trustees did not necessarily
attribute the same weight or importance to each factor. The Trustees determined
that the terms and conditions of the Fund's advisory agreement and the
compensation to TBCAM provided therein were fair and reasonable, and they
approved the advisory agreement for an initial two-year period. Some of the
factors that figured prominently in the Trustees' determination are described
below.

Nature, Extent and Quality of Services

The Board considered the nature, scope and quality of the overall services to be
provided to the Fund by the Adviser. In their deliberations as to the approval
of the Fund's advisory agreement, the Trustees were also mindful of the fact
that, by choosing to invest in the Fund, the Fund's shareholders would be
choosing to entrust TBCAM, under the supervision of the Trustees, to manage the
portion of their assets invested in the Fund.

The Trustees reviewed the background and experience of the Fund's portfolio
managers and received an overview of its organization, personnel, resources and
strategic plans. Among other things, the Trustees considered the size, education
and experience of TBCAM's investment staff.

In connection with the proposed advisory agreement with TBCAM with respect to
the Fund, the Trustees considered the fact that TBCAM had been in operation
since 1970 and had approximately $74 billion in assets under management as of
March 31, 2007, including approximately $3.7 billion in the small cap equity
strategy proposed to be utilized by the Fund. The Trustees received a
presentation by TBCAM concerning its management and investment personnel, its
investment philosophy and investment strategy.

The Trustees determined that the services proposed by TBCAM to be provided to
the Fund were of high quality and at least commensurate with industry standards.
The Board determined that TBCAM had the expertise and resources to manage the
Fund effectively.

Investment Performance

The Board reviewed investment results of certain investment company peer group
averages consisting of no load institutional funds without Rule 12b-1 plans
having an investment strategy substantially similar to the Fund selected by
TBCAM from a larger corresponding Morningstar universe of funds in the
investment category.

               Factors Considered by the Trustees in Approving the
                   Investment Advisory Agreement (Unaudited)
- --------------------------------------------------------------------------------

Advisory Fee and Other Expenses

The Board considered the advisory fee rate proposed to be paid by the Fund to
TBCAM as well as its estimated total expense ratio (after giving effect to
proposed expense limitation arrangement) and compared each to that of its peer
group, a selection of no-load institutional funds without Rule 12b-1 plans
selected by TBCAM from a larger corresponding Morningstar universe of funds.

With regard to the proposed advisory fee to be payable by the Fund to TBCAM, the
Trustees noted that the proposed management fee of 0.75% was slightly below the
0.78% average management fee of a peer group of institutional funds using a
similar strategy.

They also noted that the Fund's proposed total expense ratio of 1.00% (after
giving effect to the proposed expense limitation arrangement) was above the
0.99% average total expense ratio of the peer group, although most other funds
in the peer group were significantly larger than the Fund at projected asset
levels during its first year.

The Board also compared the fees proposed to be payable by the Fund relative to
those payable by separate account clients of TBCAM.

Based on the comparative peer group data provided, as well as the additional
scope and complexity of the services to be provided and responsibilities to be
assumed by the Adviser with respect to the Fund relative to its separate account
clients, the Board concluded that the fees proposed to be payable by the Fund
under the advisory agreement were reasonable.

The Adviser's Profitability

The Board considered the Adviser's projected profitability in managing the Fund,
as well as the methodology used to compute such profitability, and the various
direct and indirect expenses incurred by TBCAM in managing the Fund. The Board
noted that the information provided indicated that, after giving effect to the
proposed fee waivers and expense subsidies, TBCAM was projected to experience a
net operating profit in the initial year of the Fund's operations, based on the
Fund's projected asset levels during such period. TBCAM's projected
profitability was determined to be reasonable. The Trustees intend to monitor
annually the profitability of TBCAM.

Economies of Scale

The Board also considered that TBCAM may experience economies of scale as the
Fund grows and the extent to which the proposed fees reflected such economies.
They noted that projected asset levels indicated that significant economies of
scale would not be realized for some time. The Trustees concluded that,
considering initial and projected asset size over the initial term of the
advisory agreement, the implementation of breakpoints or further fee reductions
was not necessary at this time. The Trustees intend to review the need for
breakpoints in connection with further advisory agreement approval
deliberations.

Other Benefits

As part of its broader review of the advisory agreements of all of the funds in
the Trust, the Board also considered the additional benefits flowing to Mellon
as a result of its relationship with the funds. The Board relied upon its
previous review of these benefits in considering the similar benefits that may
flow to Mellon from the operation of the Fund. Mellon affiliates provide
custodial, administrative, transfer agency and securities lending services to
the funds. In each case, such affiliates were selected on the basis of a
comparative analysis of their capabilities and fees relative to those of
unaffiliated competitors.

The Board considered the fact that Mellon operates businesses other than the
Mellon Institutional Funds, some of which businesses share personnel, office
space and other resources and that these were a component of the profitability
analysis provided. The Board also considered the intangible benefits that accrue
to Mellon and its affiliates by virtue of its relationship with the funds and
the Mellon Institutional Funds as a group.

The foregoing factors were among those weighed by the Trustees in determining
that the terms and conditions of the Fund's advisory agreement and the
compensation to TBCAM provided therein are fair and reasonable and, thus, in
approving the agreement for an initial two-year period.

                     The Boston Company Small Cap Value 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 (October 1, 2007 to March 31, 2008).

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 0.93%,
     multiplied by the average account value over the period, multiplied by
     183/366 (to reflect the one-half year period).

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

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

(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.

     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 (Unaudited)
- --------------------------------------------------------------------------------

     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

     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.

     In March 2008, the FASB released Statement of Financial Accounting
     Standards No. 161, Disclosures about Derivative Instruments and Hedging
     Activities ("FAS 161"). FAS 161 requires qualitative disclosures about
     objectives and strategies for using derivatives, quantitative disclosures
     about fair value amounts of gains and losses on derivative instruments, and
     disclosures about credit-risk-related contingent features in derivative
     agreements. The application of FAS 161 is required for fiscal years
     beginning after November 15, 2008 and interim periods within those fiscal
     years. At this time, management is evaluating the implications of FAS 161
     and its impact on the financial statements and the accompanying notes 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 0.80% of the Fund's.

     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
     $12,914, for the six months ended March 31, 2008.

     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 fund accounting services for the Fund.
     For these services the Fund pays Mellon Bank a fixed fee plus asset and
     transaction based fees, as well as out-of-pocket expenses. Pursuant to this
     agreement, the Fund was charged $101,865 for the six months ended March 31,
     2008.

     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 $266,227 for the
     six months ended March 31, 2008. See Note 7 for further details.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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
     $2,151 for the six months ended March 31, 2008, 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 six months ended
     March 31, 2008, the Fund was charged $2,251, 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 $9,600, which amount is included in miscellaneous expenses in the
     statement of operations, for the six months ended March 31, 2008.

     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
     six months ended March 31, 2008, the Fund was charged $38,066 for fees
     payable to BNY Mellon Private Wealth Management.

     MBSC Securities Corporation ("MBSC"), a wholly-owned subsidiary of BNY
     Mellon and affiliate of TBCAM, is the distributor of the Fund's shares.

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the six months ended March 31, 2008 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:

     At March 31, 2008, two shareholders of record, in the aggregate held
     approximately 29.6% of the total outstanding shares of the Fund. Investment
     activities of these shareholders could have a material impact on the Fund.
     For example, a significant redemption by such shareholders could result in
     illiquid or less liquid investments comprising a larger portion of the
     Fund's Portfolio.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------

     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 six months ended March 31, 2008, the Fund received
     $17,429 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 Internal Revenue 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.

     During the current year, the Fund adopted FASB Interpretation No. 48
     "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides
     guidance for how uncertain tax positions should be recognized, measured,
     presented and disclosed in the financial statements. FIN 48 requires the
     evaluation of tax positions taken or expected to be taken in the course of
     preparing the Fund's tax returns to determine whether the tax positions are
     "more-likely-than-not" of being sustained by the applicable tax authority,
     and valuing the benefit management believes it would recover. Management
     believes the Fund will realize the full benefit of the tax positions it has
     taken and, therefore, no provision has been recorded in the accompanying
     financial statements.

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at March 31, 2008, as computed on a federal
     income tax basis, 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 March 31, 2008, 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.

     Until December 10, 2007, all cash collateral received by the Fund and other
     series of the Trust in connection with the securities lending program was
     invested in the BlackRock Cash Strategies Fund LLC (the "BlackRock Fund"),
     a private investment fund not affiliated with the Trust or its investment
     adviser. On December 10, 2007, the BlackRock Fund announced that it was
     suspending investor withdrawal privileges due to conditions related to the
     credit markets and the adverse affect of such conditions on the liquidity
     of the BlackRock Fund's portfolio holdings. Commencing on December 11,
     2007, all new cash collateral received in connection with the securities
     lending activity of the Fund and other series of the Trust was invested by
     the securities lending agent in the Dreyfus Institutional Cash Advantage
     Fund (the "Dreyfus Fund"), an affiliated money market fund registered as an
     investment company under the Investment Company Act of 1940, as amended. To
     the extent that the BlackRock Fund agreed to permit withdrawals during the
     period December 11, 2007 through March 31, 2008, the securities lending
     agent effected such withdrawals and the cash proceeds from such withdrawals
     by the Fund were reinvested in shares of the Dreyfus Fund. Repayments of
     cash collateral during the period were made from the proceeds of
     redemptions of shares of the Dreyfus Fund. See Schedule of Investments for
     further detail on the Fund's investment of cash collateral in the BlackRock
     Fund and the Dreyfus Fund as of March 31, 2008.

     The Fund loaned securities during the six months ended March 31, 2008 and
     earned interest on the invested collateral of $3,800,881 of which
     $3,177,419 was rebated to borrowers or paid in fees. At March 31, 2008, the
     Fund had securities valued at $129,748,695 on loan of which $133,358,448
     was collateralized with cash and $539,501 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. During the six months ended March 31, 2008,
     the Fund had average borrowings outstanding of $1,079,500 for a total of
     two days and incurred $290 of interest expense. The Fund did not have an
     outstanding loan balance at March 31, 2008.

    Factors Considered by the Trustees in Approving the Investment Advisory
                             Agreement (Unaudited)
- --------------------------------------------------------------------------------

The 1940 Act requires that the Board of Trustees, including a majority of its
Trustees who are not affiliated with the Fund's investment adviser or
underwriter (the "Independent Trustees") voting separately, approve the Fund's
advisory agreement and the related fees on an annual basis. In their most recent
deliberations concerning their decision to approve the continuation of the
investment advisory agreement, the Board of Trustees conducted the review and
made the determinations that are described below. In conducting this review and
in making such determinations, the Independent Trustees received from the Fund's
investment adviser, The Boston Company Asset Management LLC ("TBCAM" or the
"Adviser"), a broad range of information in response to a written request
prepared on their behalf by their own legal counsel. The Independent Trustees
met alone in a private session with their legal counsel on September 27, 2007 to
review these materials and to discuss the proposed continuation of the Fund's
advisory agreement. Representatives of management attended a portion of the
September meeting to provide an overview of the Adviser's organization,
personnel, resources and strategic plans, and to respond to questions and
comments arising from the Independent Trustees' review of the materials and
their deliberations. The entire Board then met on October 30, 2007.

The information requested by the Independent Trustees and reviewed by the entire
Board included:

(i) Financial and Economic Data: The Adviser's balance sheet and income
statements, as well as a profitability analysis of the Adviser, including a
separate presentation of the Adviser's profitability relative to that of several
publicly traded investment advisers;

(ii) Management Teams and Operations: The Adviser's Form ADV, as well as
information concerning the Adviser's executive management, portfolio management,
client service personnel and overall organizational structure, insurance
coverage, brokerage and soft dollar policies and practices;

(iii) Comparative Performance and Fees: Analyses prepared by Lipper Analytical
Services ("Lipper") regarding the Fund's historical performance, management fee
and expense ratio compared to other funds, and the Adviser's separate account
advisory fee schedules;

(iv) Specific Facts Relating to the Fund: The Adviser's commentary on the Fund's
performance and any material portfolio manager and strategy changes that may
have affected the Fund in the prior year, as well as the Fund's "fact sheets"
prepared by the Adviser providing salient data about the Fund, including the
Fund's holdings, strategies, recent market conditions and outlook, as well as
the Adviser's views concerning the issues of breakpoints in the management fee
schedule of the Fund and potential economies of scale; and

(v) Other Benefits: The benefits flowing to The Bank of New York Mellon
Corporation ("BNY Mellon") and its affiliates in the form of fees for transfer
agency, custody, administration and securities lending services provided to the
Funds by affiliates of BNY Mellon.

In considering the continuation of the Fund's advisory agreement, the Board of
Trustees, including the Independent Trustees, did not identify any single factor
as all-important or controlling, and individual Trustees did not necessarily
attribute the same weight or importance to each factor. The Trustees determined
that the terms and conditions of the advisory agreement and the compensation to
the Adviser provided therein were fair and reasonable in light of the services
performed, expenses incurred and such other matters as the Trustees considered
relevant in the exercise of their reasonable judgment. The following summary
does not detail all the matters that were considered. Some of the factors that
figured prominently in the Trustees' determination are described below.

Nature, Extent and Quality of Services

The Board considered the nature, scope and quality of the overall services
provided to the Fund by the Adviser. In their deliberations as to the
continuation of the advisory agreement, the Trustees were also mindful of the
fact that, by choosing to invest in the Fund, the Fund's shareholders have
chosen to entrust the Adviser, under the supervision of the Board, to manage the
portion of their assets invested in the Fund.

Among the specific factors the Board reviewed were the investment management,
administrative, compliance and related services provided by the Adviser. The
Board determined that the services provided were of high quality and at least
commensurate with industry standards.

The Trustees reviewed the background and experience of the Fund's two portfolio
managers and also met with senior management of the Adviser to receive an
overview of its organization, personnel, resources and strategic plans. Among
other things, the Trustees considered the size, education and experience of the
Adviser's investment staff, technological infrastructure and overall
responsiveness to changes in market conditions.

The Board determined that the Adviser had the expertise and resources to manage
the Fund effectively.

    Factors Considered by the Trustees in Approving the Investment Advisory
                             Agreement (Unaudited)
- --------------------------------------------------------------------------------

Investment Performance

The Board considered the investment performance of the Fund against a peer group
of investment companies selected by the Adviser with input from the Trustees.
The Board also compared the Fund's investment performance against the average
performance of a larger universe of funds regarded by Lipper as having similar
investment objectives and considered the Fund's performance rankings against
that universe. In addition to the information received by the Board at the
September 27, 2007 Board meeting, the Trustees received similar detailed
comparative performance information for the Fund at each regular Board meeting
during the year.

The Board considered the Fund's performance for the one-, three- and five-year
periods ended July 31, 2007 based on the Lipper materials provided to the Board
at the September 27, 2007 meeting. The Board found that the Fund outperformed
its peer group average return for the one-year period (14.03% vs. 13.34%),
three-year period (16.34% vs. 14.34%) and five-year period (18.24% vs. 16.93%).

Advisory Fee and Other Expenses

The Board considered the advisory fee rate paid by the Fund to the Adviser. The
Lipper data presenting the Fund's "net management fees" included fees paid by
the Fund, as calculated by Lipper, for administrative services provided by
Mellon Bank, N.A., the Trust's custodian. Such reporting was necessary,
according to Lipper, to allow the Board to compare the Fund's advisory fees to
those peers that include administrative fees within a blended advisory fee.

The Fund's contractual advisory fee was 0.80%, which was in the 4th (1st being
the best) quintile of its peer group of funds, the median fee of which was
0.77%. The Fund's net management fee, after giving effect to expense
limitations, was 0.799%, above the peer group median net management fee of
0.756%. Based on the Lipper data, as well as other factors discussed at the
September 27, 2007 meeting, the Board determined that the Fund's advisory fee is
reasonable relative to its peer group averages.

The Board also compared the fees payable by the Fund relative to those payable
by separate account clients of the Adviser. Based on the additional scope and
complexity of the services provided and responsibilities assumed by the Adviser
with respect to the Fund relative to these other types of clients, the Board
concluded that the fees payable under the advisory agreement were reasonable
relative to the nature and quality of the services provided.

The Board also considered the Fund's expense ratio and compared it to that of
its peer group of similar funds. The Board found that the actual net expense
ratio of 0.942% was lower than the median net expense ratio of the peer group of
1.021%, notwithstanding the fact that most of the other funds in the peer group
were larger than the Fund.

The Adviser's Profitability

The Board considered the Adviser's profitability in managing the Fund and the
Mellon Institutional Funds as a group, as well as the methodology used to
compute such profitability, and the various direct and indirect expenses
incurred by the Adviser or its affiliated investment advisers in managing the
Fund and other funds in the Mellon Institutional Funds family of funds. The
Independent Trustees had observed that the Adviser, based on the profitability
information submitted to them by the Adviser, incurred losses in managing many
of the investment companies in the Mellon Institutional Funds family of funds.
The Trustees observed that the Adviser had incurred gains in operating the Fund
in 2005 and 2006.

Economies of Scale

The Board also considered the extent to which economies of scale might be
realized as the Fund grows. They observed that the Standish Mellon Fixed Income
Fund and The Boston Company International Core Equity Fund, two of the largest
funds in the complex, already had breakpoints in their fee arrangements that
reflected economies resulting from their size. The Board also noted that at the
March 7, 2006 meeting, management had presented a Breakpoint Discussion
Memorandum that had proposed a framework for future breakpoints. The Board
concluded that, at existing asset levels and considering current asset growth
projections, the implementation of additional fee breakpoints or other fee
reductions was not necessary at this time.

                             Agreement (Unaudited)
- --------------------------------------------------------------------------------

Other Benefits

The Board also considered the additional benefits flowing to BNY Mellon as a
result of its relationship with the Mellon Institutional Funds as a group,
including revenues received by BNY Mellon affiliates in consideration of
custodial, administrative, transfer agency and securities lending services
provided by such affiliates to the Funds. In each case, such affiliates were
selected by the Board on the basis of a comparative analysis of their
capabilities and fees relative to those of unaffiliated competitors.

The Board considered the fact that BNY Mellon operates businesses other than the
Mellon Institutional Funds, some of which businesses share personnel, office
space and other resources and that these were a component of the profitability
analysis provided. The Board also considered the intangible benefits that accrue
to BNY Mellon and its affiliates by virtue of its relationship with the Funds
and the Mellon Institutional Funds as a group.

                                      * * *

The foregoing factors were among those weighed by the Trustees in determining
that the terms and conditions of the Fund's advisory agreement and the
compensation to the Adviser provided therein are fair and reasonable and, thus,
in approving the continuation of the agreement for a one-year period.

Item 11. Controls and Procedures.

         (a)  The Registrant's Principal Executive Officer and Principal
              Financial Officer concluded that the Registrant's disclosure
              controls and procedures are effective based on their evaluation
              of the Registrant's disclosure controls and procedures as of a
              date within 90 days prior to the filing date of this report (the
              "Evaluation Date" as defined in Rule 30a-3(c) under the
              Investment Company Act of 1940).

         (b)  There was no change in the Registrant's internal control over
              financial reporting (as defined in Rule 30a-3(d) under the
              Investment Company Act of 1940) during Registrant's last fiscal
              quarter that has materially affected, or is reasonably likely to
              materially affect, the Registrant's internal control over
              financial reporting. However, as reported previously on Form
              N-CSR (as filed on March 31, 2008) and Forms N-Q (as filed on
              April 22, 2008 and May 30, 2008), the Registrant had a
              significant deficiency in its internal control over financial
              reporting related to the accounting for the investment of cash
              collateral derived from


              securities lending activities in interests in cash collateral
              pooled investment vehicles. During the fiscal quarter ended March
              31, 2008, management has revised its internal control over
              financial reporting to improve the effectiveness of the controls
              to ensure that the investment in pooled investment vehicles of
              cash collateral derived from securities lending activities is
              accounted for properly.
