Mellon Institutional Funds Investment Trust Mellon Equity 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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - -------------------------------------------------------------------------------------------------- Actual $1,000.00 $1,066.80 $4.90 Hypothetical (5% return per year before expenses) $1,000.00 $1,020.19 $4.78 - ---------- + Expenses are equal to the Fund's annualized expense ratio of 0.95%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). 3 Mellon Institutional Funds Investment Trust Mellon Equity Large Cap Growth Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Holdings* Sector Investments - ------------------------------------------------------------------------------------------------- Microsoft Corp.

The Mellon Equity Large Cap Growth Fund (the "Fund"), which commenced operation on December 21, 2005, is a separate diversified investment series of the Trust. The objective of the Fund is to achieve long-term growth of capital. The Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of large capitalization companies that have total market capitalizations within the range of capitalizations of the companies in the top 80% of the Russell 1000 Growth Index at the time of purchase. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last calculated mean price (average of last bid and last offer). Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Fund's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. 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 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 differing treatments for post-October losses and capital loss carryovers 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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. 13 Mellon Institutional Funds Investment Trust Mellon Equity Large Cap Growth Fund 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 Mellon Equity Associates, LLP ("Mellon Equity"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. G. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The investment advisory fee paid to Mellon Equity for overall investment advisory, administrative services, and general office facilities, is paid monthly at the annual rate of 0.65% of the Fund's average daily net assets. Mellon Equity voluntarily agreed to limit the Fund's total annual operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.95% of the Fund's average daily net assets for the six months ended March 31, 2007. Pursuant to this arrangement, for the six months ended March 31, 2007, Mellon Equity voluntarily waived its investment advisory fee in the amount of $17,867 and reimbursed $38,840 of the Fund's operating expenses. This arrangement is voluntary and temporary and may be discontinued or revised by Mellon Equity at any time. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, Mellon Equity would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation.

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.

Transactions in Fund shares were as follows: For the December 21, 2005 Six Months Ended (commencement of March 31, 2007 operations) to (Unaudited) September 30, 2006 ---------------- ------------------ Shares sold 142,955 125,000 Shares issued to shareholders in reinvestment of distributions 339 262 ------- ------- Net increase (decrease) 143,294 125,262 ======= ======= At March 31, 2007, two shareholders, in the aggregate, of record (including MBC Investments Corp., a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of the Fund) held 99.5% of the total outstanding shares of the Fund.

The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund did not assess any redemption fees. Mellon Institutional Funds Investment Trust Mellon Equity Large Cap Growth Fund 15 Mellon Institutional Funds Investment Trust Mellon Equity Large Cap Growth Fund 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 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. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $5,658,379 Gross unrealized appreciation 408,746 Gross unrealized depreciation (131,920) ---------- Net unrealized appreciation (depreciation) $ 276,826 ========== (6) Security Lending: The Fund may lend its securities to financial institutions which the Fund deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Fund on the next business day. For the duration of a loan, the Fund receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Fund bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Fund. In the event of borrower default, the Fund generally has the right to use the collateral to offset losses incurred. The Fund may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Fund also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Fund's obligations due on the loans. The Fund loaned securities during the six months ended March 31, 2007 and earned interest on the invested collateral of $1,435 of which $1,415 was rebated to borrowers or paid in fees. At March 31, 2007, the Fund had securities valued at $81,752 on loan. See Schedule of Investments for further detail on the security positions on loan and collateral held. (7) Line of Credit: The Fund, and other funds in the Trust and subtrusts in Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") are parties to a committed line of credit facility, which enables each fund/portfolio to borrow, in the aggregate, up to $35 million. Interest is charged to each participating fund/portfolio based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating funds/portfolios at the end of each quarter. Each fund/portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating funds/portfolios. For the six months ended March 31, 2007, the expense allocated to the Fund was $9. The facility fee and interest expense are included in miscellaneous expenses on the statement of operations. For the six months ended March 31, 2007, the Fund had average borrowings outstanding of $9,000 for a total of three days and incurred $4 of interest expense. At March 31, 2007 the Fund had no borrowings outstanding. 16 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

Mellon Institutional Funds Investment Trust Mellon Equity 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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ------------------------------------------------------------------------------------- Actual $1,000.00 $1,100.30 $7.07 Hypothetical (5% return per year before expenses) $1,000.00 $1,018.20 $6.79 - ---------- + Expenses are equal to the Fund's annualized expense ratio of 1.35%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). 3 Mellon Institutional Funds Investment Trust Mellon Equity Micro Cap Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Holdings* Sector Investments - ----------------------------------------------------------------------- MarkWest Hydrocarbon, Inc.

The Mellon Equity Micro Cap Fund (the "Fund"), which commenced operations on May 1, 2006, is a separate diversified investment series of the Trust. The objective of the Fund is to achieve long-term growth of capital. The Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of micro cap U.S. companies with total market capitalizations equal to or less than $1 billion at the time of investment. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last calculated mean price (average of last bid and last offer). Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Fund's assets that are invested in one or more open ended regulated investment companies ("RICs"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. 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 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 post-October losses. 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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. D. Expenses The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated 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. 15 Mellon Institutional Funds Investment Trust Mellon Equity Micro Cap Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- E. Commitments and contingencies In the normal course of business, the Fund may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Fund under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risks of loss to be remote. F. Affiliated issuers Affiliated issuers are investment companies advised by Mellon Equity Associates, LLP ("Mellon Equity"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. G. New Accounting Requirements In July 2006, the Financial Accounting Standards Board issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined. In addition, on September 20, 2006, the FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The investment advisory fee paid to Mellon Equity for overall investment advisory, administrative services, and general office facilities, is paid monthly at the annual rate of 1.00% of the Fund's average daily net assets. Mellon Equity voluntarily agreed to limit the Fund's total annual operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 1.35% of the Fund's average daily net assets for the six month period ended March 31, 2007. Pursuant to this arrangement, for the six month period ended March 31, 2007, Mellon Equity voluntarily reimbursed $44,964 of the Fund's operating expenses. This arrangement is voluntary and temporary and may be discontinued or revised by Mellon Equity at any time. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, Mellon Equity would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of Mellon Equity, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as, out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $3,134 for the six months ended March 31, 2007. The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of Mellon Equity, to provide custody, administration and accounting services for the Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $25,030 for the six months ended March 31, 2007. The Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Fund's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $2,634 for the six months ended March 31, 2007. See Note 6 for further details. 16 Mellon Institutional Funds Investment Trust Mellon Equity Micro Cap Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,105, which is included as miscellaneous expenses in the statement of operations. No other director, officer or employee of Mellon Equity or its affiliates receives any compensation from the Trust or the Fund for serving as an officer or Trustee of the Trust. The Fund pays each Trustee who is not a director, officer or employee of Mellon Equity or its affiliates an annual fee and a per meeting fee as well as reimbursement for travel and out-of-pocket expenses. In addition, the Trust pays the legal fees for the independent counsel of the Trustees. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of Mellon Financial Corporation and an affiliate of Standish Mellon, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $500, which is included as miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. The Fund pays 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. (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, 2007 were as follows: Purchases Sales ----------- ----------- Non-U.S. Government Securities $ 7,911,721 $ 7,883,111 =========== =========== (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 May 1, 2006 Six Months Ended (commencement of March 31, 2007 operations) to (Unaudited) September 30, 2006 ---------------- ------------------ Shares sold 2,520 473,106 ----- ------- Net increase (decrease) 2,520 473,106 ===== ======= At March 31, 2007, two shareholders of record (including MBC Investments Corp., a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of the Fund) held in the aggregate 99.2% of the total outstanding shares of the Fund. Investment activities of these shareholders could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund did not assess any redemption fees. 17 Mellon Institutional Funds Investment Trust Mellon Equity Micro Cap Fund 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 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. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $10,978,032 ----------- Gross unrealized appreciation 706,587 Gross unrealized depreciation (406,385) ----------- Net unrealized appreciation (depreciation) $ 300,202 =========== (6) Security Lending: The Fund may lend its securities to financial institutions which the Fund deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Fund on the next business day. For the duration of a loan, the Fund receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Fund bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Fund. In the event of borrower default, the Fund generally has the right to use the collateral to offset losses incurred. The Fund may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Fund also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Fund's obligations due on the loans. The Fund loaned securities during the six months ended March 31, 2007 and earned interest on the invested collateral of $25,537 of which $18,395 was rebated to borrowers or paid in fees. At March 31, 2007, the Fund had securities valued at $1,403,362 on loan. See Schedule of Investments for further detail on the security positions on loan and collateral held. (7) Line of Credit: The Fund, and other funds in the Trust and subtrusts in Mellon Institutional Funds Master Portfolio (the"Portfolio Trust") are parties to a committed line of credit facility, which enables each fund/portfolio to borrow, in the aggregate, up to $35 million. Interest is charged to each participating fund/portfolio based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating funds/portfolios at the end of each quarter. Each fund/portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating funds/portfolios. For the six months ended March 31, 2007, the expense allocated to the Fund was $58. The facility fee and interest expense are included in miscellaneous expenses on the statement of operations. For the six months ended March 31, 2007, the Fund had average borrowings outstanding of $1,000 for a total of one day and incurred $0 of interest expense. At March 31, 2007, the Fund had no borrowings outstanding. 18 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

This report is not authorized for distribution to prospective investors in the Fund unless preceded or accompanied by an effective prospectus. Any information in this shareholder report regarding market or economic trends or the factors influencing the Fund's historical or future performance are 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 performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. The Fund files its complete schedule of portfolio holdings with the Securities and Exchange Commission (SEC) for the first and third quarters of each fiscal year on Form N-Q.

Mellon Institutional Funds Investment Trust Mellon Institutional Market Neutral 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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ------------------------------------------------------------------------------------------------------------------------------------ Actual $1,000.00 $1,007.40 $6.26 Hypothetical (5% return per year before expenses) $1,000.00 $1,018.70 $6.29 - ---------------- + Expenses are equal to the Fund's annualized expense ratio of 1.25% (excluding fees in lieu of dividends), multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). 3 Mellon Institutional Funds Investment Trust Mellon Institutional Market Neutral Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Long Holdings* Sector Net Assets - -------------------------------------------------------------------------------------------------------- NutruSystem, Inc.

Mellon Institutional Market Neutral Fund (the "Fund"), which commenced operations on December 21, 2005, is a separate diversified investment series of the Trust. The objective of the Fund is to achieve investment returns exceeding the 3-month U.S. Treasury Bill from a broadly diversified portfolio of U.S. stocks while neutralizing the general risks associated with stock market investing. The Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity 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 market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Fund's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. Exchange traded options and futures are valued at the settlement price determined by the relevant exchange. 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 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 post-October losses. 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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. 17 Mellon Institutional Funds Investment Trust Mellon Institutional Market Neutral Fund 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. Securities Sold Short The Fund sells a security short by borrowing it from a third party and selling it at the then-current market price. The Fund is then obligated to buy the security on a later date in order to return the security to the lender. Short sales, therefore, involve the risk that the Fund will incur a loss by subsequently having to buy a security at a higher price than the price at which the Fund previously sold the security short. Moreover, because a Fund's loss on a short sale would arise from increases in the value of the security sold short, the extent of such loss, like the potential increase in the price of the security sold short, is theoretically unlimited. By contrast, a Fund's risk of loss on a long position arises from the possible decrease in the value of the security and therefore is limited by the fact that a security's value cannot drop below zero. The Fund may be required to pay a fee to borrow a security sold short. These short sales are collateralized by cash equivalents or securities held with the Fund's prime broker and segregated account at the Fund's custodian. The collateral required is determined daily by reference to the market value of the short positions. Dividends paid by the issuer of the security sold short are paid by the Fund to the lender, recorded on the ex-date of the dividend and recorded as an expense on the Statement of Operations. Liabilities for securities sold short are reported at market value in the Statement of Assets and Liabilities. G. Affiliated issuers Affiliated issuers are investment companies advised by Franklin Portfolio Associates ("Franklin Portfolio"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. H. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined. In addition, on September 20, 2006, 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. 18 Mellon Institutional Funds Investment Trust Mellon Institutional Market Neutral Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (2) Investment Advisory Fee and Other Transactions With Affiliates: The investment advisory fee paid to Franklin Portfolio for overall investment advisory and administrative services, and general office facilities, is paid monthly at the annual rate of 1.00% of the Fund's average daily net assets. Franklin Portfolio voluntarily agreed to limit the Fund's total annual operating expenses (excluding brokerage commissions, dividend expense on short sales, taxes and extraordinary expenses) to 1.25% of the Fund's average daily net assets for the six months ended March 31, 2007. Pursuant to this arrangement, for the six months ended March 31, 2007, Franklin Portfolio voluntarily waived its investment advisory fee in the amount of $12,911 and reimbursed the Fund for $69,355 of its operating expenses. This arrangement is voluntary and temporary and may be discontinued or revised by Franklin Portfolio at any time. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, Franklin Portfolio would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of Franklin Portfolio, 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 $3,624 for the six months ended March 31, 2007. Prior to January 1, 2007, The Trust compensated Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of Franklin Portfolio, for custody services for the Fund. For these services the Fund paid 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 $7,211 for the six months ended March 31, 2007. Effective January 1, 2007, The Trust entered into an agreement with Custodial Trust Company ("CTC") to provide custody services for the Fund. For these services, the Fund pays a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. CTC is not an affiliate of the Fund. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,106, which is included in miscellaneous expenses in the statement of operations. No other director, officer or employee of Franklin Portfolio 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 Franklin Portfolio 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 Mellon Financial Corporation and an affiliate of Franklin Portfolio, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $950, which is included in miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. The Fund pays 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, 2007, the Fund was not charged an administrative service fee. (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, 2007 were as follows: Covers on Securities Purchases Securities Sold Short Sales Sold Short ---------- --------------------- ---------- ---------- Non-U.S. Government Securities $1,918,633 2,268,957 $2,268,845 2,061,217 ========== ========= ========== ========= 19 Mellon Institutional Funds Investment Trust Mellon Institutional Market Neutral Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (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 December 21, 2005 For the (commencement of Six Months Ended operations) to March 31, 2007 September 30, 2006 ---------------- ------------------ Shares sold 39 125,986 Shares issued to shareholders in reinvestment of distributions 4,765 -- Shares redeemed (153) -- ----- ------- Net increase (decrease) 4,651 125,986 ===== ======= At September 30, 2006, one shareholder of record (MBC Investments Corp., a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of the Fund) held 99.3% of the total outstanding shares of the Fund. Investment activities of this shareholder could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund received $1 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. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $5,157,190 ---------- Gross unrealized appreciation $ 316,358 Gross unrealized depreciation (281,241) ---------- Net unrealized appreciation (depreciation) $ 35,117 ========== (6) Line of Credit: The Fund, and other funds in the Trust and subtrusts in Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") are parties to a committed line of credit facility, which enables each fund/portfolio to borrow, in the aggregate, up to $35 million. Interest is charged to each participating fund/portfolio based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating funds/portfolios at the end of each quarter. For the six months ended March 31, 2007, the Fund was not charged a commitment fee. During the six months ended March 31, 2007, the Fund did not borrow under the credit facility. 20 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

Mellon Institutional Funds Investment Trust 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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ----------------------------------------------------------------------------------------------- Actual $1,000.00 $1,113.90 $6.06 Hypothetical (5% return per year before expenses) $1,000.00 $1,019.20 $5.79 - ---------- + Expense are equal to the Fund's annualized expense ratio of 1.15% multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one half year period). 3 Mellon Institutional Funds Investment Trust Newton International Equity Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Holdings* Country Sector Investments - ---------------------------------------------------------------------------------------------------------- Novartis AG Switzerland Healthcare 2.7% Nestle SA Switzerland Consumer Staples 2.6 Toyota Motor Corp.

The Newton International Equity Fund (the "Fund"), which commenced operation on December 21, 2005, is a separate diversified investment series of the Trust. The objective of the Fund is to achieve long-term growth of capital. The Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in common stocks or securities convertible into common stocks (such as convertible preferred stocks, warrants and convertible bonds) of foreign companies and depositary receipts evidencing ownership in such securities. At least 75% of the Fund's net assets will be invested in countries represented in the Morgan Stanley Capital International Europe, Australasia and the Far East (MSCI EAFE) Index. The Fund may invest up to 20% of its assets in emerging market countries. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last calculated mean price (average of last bid and last offer). Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Fund's assets that are invested in one or more open ended management investment companies ("RICS"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. 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. 14 Mellon Institutional Funds Investment Trust Newton International Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. The Fund's distributions from capital gains, if any, after reduction of capital losses will be declared and distributed at least annually. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless the shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for foreign currency transactions and losses deferred due to wash sales. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income (loss), accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (loss) and accumulated net realized gain (loss) on investments may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. Section 988 of the Internal Revenue Code provides that gains or losses on certain transactions attributable to fluctuations in foreign currency exchange rates must be treated as ordinary income or loss. For financial statement purposes, such amounts are included in net realized gains or losses. D. Expenses The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated among funds of the Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds. E. Foreign currency transactions The Fund maintains its books and records in U.S. dollars. Investment security valuations and other assets and liabilities initially expressed in foreign currencies are converted into U.S. dollars based upon current currency exchange rates. Purchases and sales of foreign investment securities and income and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. F. Foreign Investment risk There are certain additional risks involved in investing in foreign securities that are not inherent in investments in domestic securities. These risks may involve adverse political and economic developments, including the possible imposition of capital controls or other foreign governmental laws or restrictions. In addition, the securities of some foreign companies and securities markets are less liquid and at times may be more volatile than securities of comparable U.S. companies and U.S. securities markets. The risks described above apply to an even greater extent to investments in emerging markets. The securities markets of emerging countries are generally smaller, less developed, less liquid, and more volatile than the securities markets of the U.S. and developed foreign markets. G. Commitments and contingencies In the normal course of business, the Fund may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Fund under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risks of loss to be remote. H. Affiliated issuers Affiliated issuers are investment companies advised by Newton Capital Management Ltd. ("Newton"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. 15 Mellon Institutional Funds Investment Trust Newton International Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- I. New Accounting Requirements In July 2006, the Financial Accounting Standards Board issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, the FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The investment advisory fee paid to Newton for overall investment advisory and administrative services, and general office facilities, is paid monthly at the annual rate of 0.80% of the Fund's average daily net assets. Newton voluntarily agreed to limit the Fund's total annual operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 1.15% of the Fund's average daily net assets for the six month ended March 31, 2007. Pursuant to this agreement, for the six month ended March 31, 2007, Newton voluntarily waived $57,029 of its investment advisory fee. This arrangement is voluntary and temporary and may be discontinued or revised by Newton at any time. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, Newton would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of 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 $3,555, for the six months ended March 31, 2007. The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of Newton, to provide custody, administration and accounting services for the Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $66,363 for the six months ended March 31, 2007. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,105, which 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 Mellon Financial Corporation and an affiliate of Standish Mellon, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $750, which is included in miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. The Fund pays 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, 2007, the Fund was not charged an administrative service fee. 16 Mellon Institutional Funds Investment Trust Newton International Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (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, 2007 were as follows: Purchases Sales ------------ ------------ Non-U.S. Government Securities $24,900,934 $19,284,289 =========== =========== (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 December 31, 2005 Six Months Ended (commencement of March 31, 2007 operations) to (Unaudited) September 30, 2006 ---------------- ------------------ Shares sold 268,939 1,549,732 Shares issued to shareholders in reinvestment of distributions 1,746 741 Shares redeemed -- (5) ------- --------- Net increase (decrease) 270,685 1,550,468 ======= ========= At March 31, 2007, three shareholders of record, in the aggregate held approximately 97% of the total outstanding shares of the Fund. Investment activities of these shareholders could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund did not assess any redemption fees. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $38,414,628 ----------- Gross unrealized appreciation 5,506,145 Gross unrealized depreciation ( 650,607) ----------- Net unrealized appreciation (depreciation) $ 4,855,538 =========== (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: 17 Mellon Institutional Funds Investment Trust Newton International Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- Forward Currency Exchange Contracts The Fund may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Fund primarily to protect the value of the Fund's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At March 31, 2007, the Fund held foreign currency exchange contracts. See schedule of investments for further details. (7) Line of Credit The Fund, and other funds in the Trust and subtrusts in Mellon Institutional Funds Master Portfolio (the"Portfolio Trust") are parties to a committed line of credit facility, which enables each fund/portfolio to borrow, in the aggregate, up to $35 million. Interest is charged to each participating fund/portfolio based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating funds/portfolios at the end of each quarter. The participating portfolios and funds also pay an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating portfolios/funds. For the six months ended March 31, 2007, the expense allocated to the Fund was $797. The facility fee and interest expense are included in miscellaneous expenses on the statement of operations. For the six months ended March 31, 2007, the Fund had average borrowings outstanding of $212,500 for a total of nine days and incurred $1,524 of interest expense. At March 31, 2007, the Fund had a $200,000 loan balance outstanding. 18 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ------------------------------------------------------------------------------------------------------------- Actual $1,000.00 $1,226.50 $8.05 Hypothetical (5% return per year before expenses) $1,000.00 $1,017.70 $7.29 - ---------------- + Expenses are equal to the Fund's annualized expense ratio of 1.45%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). 3 Mellon Institutional Funds Investment Trust The Boston Company Emerging Markets Core Equity Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Holdings* Country Sector Investments - ------------------------------------------------------------------------------------------------------- China Mobile Ltd.

The Boston Company Emerging Markets Core Equity Fund (the "Fund"), which commenced operation on July 10, 2006, is a separate diversified investment series of the Trust. The objective of the Fund is to achieve long-term growth of capital. The Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of companies that are located in foreign countries represented in the Morgan Stanley Capital International Emerging Market (MSCI EM) Index. The Fund may also enter into equity index futures contracts based primarily on the indices of the countries included in the MSCI EM Index and Canada. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last calculated mean price (average of last bid and last offer). Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which accurate market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available 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. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers, including counterparties or pricing servicees. 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 the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity. Dividend income is recorded on 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. 13 Mellon Institutional Funds Investment Trust The Boston Company Emerging Markets Core Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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 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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. Section 988 of the Internal Revenue Code provides that gains or losses on certain transactions attributable to fluctuations in foreign currency exchange rates must be treated as ordinary income or loss. For financial statement purposes, such amounts are included in net realized gains or losses. D. Expenses The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated among 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 Mellon Financial Corporation, or its affiliates. I. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including 14 Mellon Institutional Funds Investment Trust The Boston Company Emerging Markets Core Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The investment advisory fee paid to TBCAM for overall investment advisory and administrative services, and general office facilities, is paid monthly at the annual rate of 1.10% of the Fund's average daily net assets. TBCAM voluntarily agreed to limit the Fund's total annual operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 1.45% of the Fund's average daily net assets for the six months ended March 31, 2007. For the six months ended March 31, 2007, TBCAM voluntarily waived its investment advisory fee in the amount of $37,478 and reimbursed the Fund for $36,115 of its operating expenses. This arrangement is voluntary and temporary and may be discontinued or revised by TBCAM at any time. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as, out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $2,828, for the six months ended March 31, 2007. The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation 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 $47,330 for the six months ended March 31, 2007. The Trust also entered into an agreement with Mellon Bank, to perform certain securities lending activities and to act as the Fund's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $354 for the six months ended March 31, 2007. See Note 7 for further details. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $1,413, which 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 Mellon Financial Corporation and an affiliate of TBCAM, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $775, which is included in miscellaneous expenses in the statement of operations for the six months ended March 31, 2007. The Fund pays 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. 15 Mellon Institutional Funds Investment Trust The Boston Company Emerging Markets Core Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (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, 2007 were as follows: Purchases Sales ----------- ---------- Non-U.S. Government Securities $ 4,359,233 $3,439,466 =========== ========== (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 July 10, 2006 For the (commencement of Six Months Ended operations) to March 31, 2007 September 30, 2006 ---------------- ------------------ Shares sold 47,693 277,002 Shares issued to shareholders in reinvestment of distributions 1,599 -- Shares redeemed (8,809) -- ------ ------- Net increase (decrease) 40,483 277,002 ====== ======= At March 31, 2007, one shareholder of record (MBC Investments Corp., a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of the Fund) held 79% of the total outstanding shares of the Fund. Investment activities of this shareholder could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund did not assess any redemption fees. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $7,004,532 ---------- Gross unrealized appreciation 1,253,696 Gross unrealized depreciation (120,693) ---------- Net unrealized appreciation (depreciation) $1,133,003 ========== 16 Mellon Institutional Funds Investment Trust The Boston Company Emerging Markets Core Equity Fund 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 Currency Exchange Contracts The Fund may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Fund primarily to protect the value of the Fund's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At March 31, 2007, the Fund did not hold 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. The Fund loaned securities during the six months ended March 31, 2007 and earned interest on the invested collateral of $2,554 of which $1,716 was rebated to borrowers or paid in fees. At March 31, 2007, the Fund had securities valued at $232,580 on loan. See Schedule of Investments for further detail on the security positions on loan and collateral held. (8) Line of Credit The Fund, and other funds in the Trust and subtrusts in Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") are parties to a committed line of credit facility, which enables each fund/portfolio to borrow, in the aggregate, up to $35 million. Interest is charged to each participating fund/portfolio based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating funds/portfolios at the end of each quarter. Each fund/portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating funds/portfolios. For the six months ended March 31, 2007, the expense allocated to the Fund was $111. The facility fee and interest expense are included in miscellaneous expenses on the statement of operations. For the six months ended March 31, 2007, the Fund had average borrowings outstanding of $47,750 for a total of four days and incurred $31 of interest expense. At March 31, 2007 the Fund had no borrowings outstanding. 17 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

This report is not authorized for distribution to prospective investors in the Fund unless preceded or accompanied by an effective prospectus.

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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ------------------------------------------------------------------------------------------------------------------ Actual $1,000.00 $1,154.40 $4.19 Hypothetical (5% return per year before expenses) $1,000.00 $1,021.04 $3.93 - ----------- + Expenses are equal to the Fund's annualized expense ratio of 0.78%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). The example reflects the combined expenses of the Fund and the master portfolio in which it invests all its assets. 3 Mellon Institutional Funds Investment Trust The Boston Company International Core Equity Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- The Boston Company International Core Equity Fund invests all of its investable assets in an interest of The Boston Company International Core Equity Portfolio (See Note 1 of the Fund's Notes to Financial Statements).

The Boston Company International Core Equity Fund (the "Fund") is a separate diversified investment series of the Trust. The object of the Fund is to achieve long-term growth of capital. The Fund invests all of its investable assets in an interest of The Boston Company International Core Equity Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust, and has the same investment objective as the Fund. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of companies represented in the MSCI Europe, Australia, Far East (EAFE) Index and Canada. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. As of March 31, 2007 the Fund owned 89% of the Portfolio's net assets. The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations 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. The Fund records its investments in the Portfolio at value. The Portfolio values its securities at value as discussed in Note 1A of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. B. Securities transactions and income The Fund's investment in the Portfolio is recorded on settlement date. The Portfolio's securities transactions are recorded as of the trade date as discussed in Note 1B of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. All realized and unrealized gains and losses of the Fund represent pro rata shares of gains and losses of the Portfolio. 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 are declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences which may result in reclassifications, are primarily due to differing treatments for foreign currency transactions and losses deferred due to wash sales. Permanent book and tax basis differences relating to shareholder distributions 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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. Section 988 of the Internal Revenue Code provides that gains or losses on certain transactions attributable to fluctuations in foreign currency exchange rates must be treated as ordinary income or loss. For financial statement purposes, such amounts are included in net realized gains or losses. D. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust and/or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. 9 Mellon Institutional Funds Investment Trust The Boston Company International Core Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The Fund does not directly pay any investment advisory fees, but indirectly bears its pro rata share of the compensation paid by the Portfolio to The Boston Company Asset Management, LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, for such services. See Note 2 of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $44,547 for the six months ended March 31, 2007. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,121. No other director, officer or employee of TBCAM or its affiliates receives any compensation from the Trust or the Portfolio Trust 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. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of Mellon Financial Corporation 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 is included as miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. The Fund pays 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, 2007, the Fund was charged $74,977 for fees payable to Mellon Private Wealth Management. 10 Mellon Institutional Funds Investment Trust The Boston Company International Core Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (3) Investment Transactions Increases and decreases in the Fund's investment in the Portfolio for the six months ended March 31, 2007 aggregated $549,448,606 and $182,221,859, respectively. The Fund receives a proportionate share of the Portfolio's income, expense and realized and unrealized gains and losses based on applicable tax allocation rules. Book/tax differences arise when changes in proportionate interest for funds investing in the Portfolio occur. (4) Shares of Beneficial Interest The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest having a par value of one cent per share. Transactions in Fund shares were as follows: For the For the Six Months Ended Year Ended March 31, 2007 September 30, 2006 ---------------- ------------------ Shares sold 12,009,648 45,334,340 Shares issued to shareholders in reinvestment of distributions 843,302 479,216 Shares redeemed (2,775,678) (2,520,245) ---------- ---------- Net increase (decrease) 10,077,272 43,293,311 ========== ========== 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 are acquired through reinvestment of distributions. For the year ended March 31, 2007, the Fund received $18,771 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.

The Boston Company International Core Equity Portfolio (the "Portfolio") is a separate diversified investment series of the Portfolio Trust. The objective of the Portfolio is to achieve long-term growth of capital. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of companies that are represented in the MSCI Europe, Australia, Far East Index (EAFE) and Canada. At March 31, 2007, there were two funds, The Boston Company International Core Equity Fund and Dreyfus Premier International Equity Fund (the "Feeder Funds") invested in the Portfolio. The value of the Feeder Funds' investment in the Portfolio reflects the Feeder Funds' proportionate interests in the net assets of the Portfolio. At March 31, 2007, The Boston Company International Core Equity Fund (the "Fund") and the Dreyfus Premier International Equity Fund held approximately 89% and 11% interests in the Portfolio, respectively. The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities 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 market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Portfolio's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Portfolio'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, counterparties or pricing services. Because foreign markets may be open at different times than the New York Stock Exchange ("NYSE"), the value of the Portfolio'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 Portfolio may value its assets by a method the Trustees believe accurately reflects the fair value. The Trustees have adopted fair value pricing procedures, which, among other things, require the Portfolio to fair value such securities if there has been a movement in the U.S. market that exceeds a specified threshold. Although the threshold may be revised from time to time by the Trustees 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 Portfolio 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 Portfolio acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and will then be valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity. Dividend income is recorded on ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. 22 Mellon Institutional Funds Master Portfolio The Boston Company International Core Equity Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Portfolio does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. Net realized gains and losses on foreign currency transactions represent gains and losses on disposition of foreign currencies and forward foreign currency exchange contracts, currency gains and losses realized between the trade and settlement dates on securities transactions, and the difference between the amount of investment income and foreign withholding taxes recorded on the Portfolio's books and the U.S. dollar equivalent amounts actually received or paid. C. Income taxes The Portfolio is treated as a partnership for federal tax purposes. No provision is made by the Portfolio for federal or state income taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes. Since at least one of the Portfolio's investors is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the source of income and diversification requirements applicable to regulated investment companies (under the Internal Revenue Code) in order for its investors to satisfy them. Section 988 of the Internal Revenue Code provides that gains or losses on certain transactions attributable to fluctuations in foreign currency exchange rates must be treated as ordinary income or loss. For financial statement purposes, such amounts are included in net realized gains or losses. D. Foreign currency transactions The Portfolio maintains its books and records in U.S. dollars. Investment security valuations, other assets, and liabilities initially expressed in foreign currencies are converted into U.S. dollars based upon current currency exchange rates. Purchases and sales of foreign investment securities and income and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. E. 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. F. Commitments and contingencies In the normal course of business, the Portfolio may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Portfolio under these arrangements is unknown, as this would involve future claims that may be made against the Portfolio that have not yet occurred. However, based on experience, the Portfolio expects the risks of loss to be remote. G. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among the funds of the Trust or the portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. H. Affiliated issuers Affiliated issuers are investment companies advised by The Boston Company Asset Management Company LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. 23 Mellon Institutional Funds Master Portfolio The Boston Company International Core Equity Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- I. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to TBCAM for overall investment advisory, and administrative services, and general office facilities, is paid monthly at the annual rate of 0.80% of the first $500 million of the Portfolio's average daily net assets, 0.75% of the next $500 million, and 0.70% of the next $500 million, 0.60% of the next $500 millon, and 0.50% on assets over $2 billion. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Portfolio Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide custody, administration and accounting services for the Portfolio. For these services the Portfolio pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement the Portfolio was charged $675,332 for the six months ended March 31, 2007. The Portfolio Trust also entered into an agreement with Mellon Bank, to perform certain securities lending activities and to act as the Portfolio's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $15, for the six months ended March 31, 2007. See Note 6 for further details. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's and Portfolio Trust's Chief Compliance Officer. No other director, officer or employee of TBCAM or its affiliates receives any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust. The Fund and Portfolio Trust pays each Trustee who is not a director, officer or employee of TBCAM or its affiliates (the "Independent Trustees") an annual fee and the Portfolio Trust pays each Independent Trustee a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Portfolio Trust pays the legal fees for the counsel to the Independent Trustees. (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, 2007 were as follows: Purchases Sales -------------- ------------ Non-U.S. Government Securities $1,268,021,863 $810,566,503 ============== ============ 24 Mellon Institutional Funds Master Portfolio The Boston Company International Core Equity Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (4) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $2,556,541,454 -------------- Gross unrealized appreciation 468,165,883 Gross unrealized depreciation (17,266,298) -------------- Net unrealized appreciation (depreciation) $ 450,899,585 ============== (5) Financial Instruments: In general, the following instruments are used for hedging purposes as described below. However, these instruments may also be used to seek to enhance potential gain in circumstances where hedging is not involved. The Portfolio may trade the following financial instruments with off-balance sheet risk: Forward currency exchange contracts The Portfolio may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Portfolio primarily to protect the value of the Portfolio's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At March 31, 2007, the Portfolio held open foreign currency exchange contracts. See Schedule of Investments for further details. Futures contracts The Portfolio may enter into financial futures contracts for the purchase or sale of securities, or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements, the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments, known as variation margin, are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized appreciation or depreciation by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may also arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. At March 31, 2007, the Portfolio held open financial futures contracts. See Schedule of Investments for further details. 25 Mellon Institutional Funds Master Portfolio The Boston Company International Core Equity Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (6) Security Lending: The Portfolio may lend its securities to financial institutions which the Portfolio deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Portfolio on the next business day. For the duration of a loan, the Portfolio receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Portfolio bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Portfolio. In the event of borrower default, the Portfolio generally has the right to use the collateral to offset losses incurred. The Portfolio may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Portfolio also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Portfolio's obligations due on the loans. The Portfolio loaned securities for the six months ended March 31, 2007 and earned interest on the invested collateral of $246 of which $210 was rebated to borrowers or paid in fees. At March 31, 2007, the Portfolio had securities valued at $6,485 on loan. See Schedule of Investments for further detail on the security positions on loan and collateral held. (7) Line of Credit: The Portfolio, and other subtrusts in the Portfolio Trust and funds in the Trust are parties to a committed line of credit facility, which enables each portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is charged to each participating portfolio/fund based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating portfolios/funds at the end of each quarter. The participating portfolios and funds also pay an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating portfolio/fund. For the six months ended March 31, 2007, the expense allocated to the Portfolio was $7,121. The facility fee and interest expense is aggregated with miscellaneous expenses on the Statement of Operations. For the six months ended March 31, 2007, the Portfolio did not borrow from the line of credit during the period. 26 Mellon Institutional Funds Master Portfolio The Boston Company International Core Equity Portfolio Factors Considered by Board of Trustees in Approving 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. The Fund is not a party to an investment advisory agreement directly with any investment adviser and does not invest directly in portfolio securities. Instead, the Fund invests all of its investable assets in The Boston Company International Core Equity Portfolio (the "Portfolio"), which is managed by The Boston Company Asset Management LLC ("TBCAM"). The Fund's Board of Trustees determines annually whether the Fund should continue to invest in the Portfolio. The members of the Fund's Board of Trustees also serve as the Board of Trustees of the Portfolio. In that capacity, they consider annually whether to continue the investment advisory agreement between the Portfolio and TBCAM. 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 Portfolio's investment adviser, TBCAM ("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 28, 2006 to review these materials and to discuss the proposed continuation of the Fund's advisory agreement. Representatives of the Adviser attended a portion of the September meeting to provide an overview of its 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 17, 2006. 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 (rather than the Portfolio alone), 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 and Portfolio, including the Portfolio'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 Portfolio and potential economies of scale; and (v) Other Benefits: The benefits flowing to Mellon Financial Corporation ("Mellon") in the form of revenues received by Mellon affiliates in consideration of custodial, administrative, transfer agency and securities lending services provided by such affiliates to the Funds. In considering the continuation of the Portfolio'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 Portfolio 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 Portfolio'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 and overall responsiveness to changes in market conditions. The Board determined that the Adviser had the expertise and resources to manage the Portfolio effectively. 27 Mellon Institutional Funds Master Portfolio The Boston Company International Core Equity Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Investment Performance The Board considered the investment performance of the Fund (rather than the Portfolio alone) 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 28, 2006 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, 2006 based on the Lipper materials provided to the Board at the September 28, 2006 meeting. The Board found that the Fund outperformed its peer group average returns for the one-year period (24.65% vs. 22.50%), three-year period (27.11% vs. 21.60%) and five-year period (15.50% vs. 9.94%). Advisory Fee and Other Expenses The Board considered the advisory fee rate paid by the Portfolio to the Adviser. The Lipper data presenting the Portfolio's "net management fees" included fees paid by the Portfolio, as calculated by Lipper, for administrative services provided by Mellon Bank, N.A., the Portfolio's custodian. Such reporting was necessary, according to Lipper, to allow the Board to compare the Portfolio's advisory fees to those peers that include administrative fees within a blended advisory fee. The Portfolio's contractual advisory fee was 0.744% (based on the following breakpoints: 0.800% of the first $500 million; 0.750% of the next $500 million; and 0.700% over $1 billion), in the 2nd quintile (1st being the best) of its peer group of funds, the median fee of which was 0.818%. The Portfolio's net management fee was 0.908% (which included 0.111% in administrative service fees under Lipper's calculation methodology), higher than the peer group median net management fee of 0.672%. Based on the Lipper data, as well as other factors discussed at the September 28, 2006 meeting, the Board determined that the Portfolio's advisory fee is reasonable relative to its peer group averages. The Board also compared the fees payable by the Portfolio 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 Portfolio 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 (rather than solely the Portfolio'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 1.013% was slightly higher than the median net expense ratio of the peer group of 1.007%. However, 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 Portfolio and 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 adviser, Standish Mellon Asset Management Company LLC ("Standish Mellon") in managing the Portfolio and other funds in the Mellon Institutional Funds family of funds. The Independent Trustees had observed that the Adviser, based on profitability information submitted to them by the Adviser, incurred marginal profitability in managing most of the investment companies in the Mellon Institutional Funds family of funds. The Trustees observed that the Adviser had experienced profits in operating the Portfolio in both 2004 and 2005 and concluded these were not excessive. 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 Portfolio, 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. 28 Mellon Institutional Funds Master Portfolio The Boston Company International Core Equity Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Other Benefits The Board also considered the additional benefits flowing to Mellon as a result of its relationship with the Mellon Institutional Funds as a group, including revenues received by 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 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 Portfolio'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. 29 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

The Boston Company International Small Cap Fund (the "Fund") is a separate diversified investment series of the Trust. The object of the Fund is to achieve long-term growth of capital. The Fund invests all of its investable assets in an interest of The Boston Company International Small Cap Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust, and has the same investment objective as the Fund. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of companies represented in the Citigroup World Extended Market Ex. U.S. (EMI Ex-U.S.) Index. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. As of March 31, 2007 the Fund owned 69% of the Portfolio's net assets. The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations 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. The Fund records its investments in the Portfolio at value. The Portfolio values its securities at value as discussed in Note 1A of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. B. Securities transactions and income The Fund's investment in the Portfolio is recorded on settlement date. The Portfolio's securities transactions are recorded as of the trade date as discussed in Note 1B of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. All realized and unrealized gains and losses of the Fund represent pro rata shares of gains and losses of the Portfolio. 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 are declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences which may result in reclassifications, are primarily due to differing treatments for foreign currency transactions and losses deferred due to wash sales Permanent book and tax basis differences relating to shareholder distributions 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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. Section 988 of the Internal Revenue Code provides that gains or losses on certain transactions attributable to fluctuations in foreign currency exchange rates must be treated as ordinary income or loss. For financial statement purposes, such amounts are included in net realized gains or losses. D. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust and/or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. 9 Mellon Institutional Funds Investment Trust The Boston Company International Small Cap Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The Fund does not directly pay any investment advisory fees, but indirectly bears its pro rata share of the compensation paid by the Portfolio to The Boston Company Asset Management, LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, for such services. See Note 2 of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $24,702 for the six months ended March 31, 2007. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,111, which is included as 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 Portfolio Trust 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. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $3,500, which is included as miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. The Fund pays 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, 2007, the Fund was charged $55,726 for fees payable to Mellon Private Wealth Management. 10 Mellon Institutional Funds Investment Trust The Boston Company International Small Cap Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (3) Investment Transactions Increases and decreases in the Fund's investment in the Portfolio for the six months ended March 31, 2007 aggregated $108,750,979 and $136,762,398, respectively. The Fund receives a proportionate share of the Portfolio's income, expense and realized and unrealized gains and losses based on applicable tax allocation rules. Book/tax differences arise when changes in proportionate interest for funds investing in the Portfolio occur. (4) Shares of Beneficial Interest The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest having a par value of one cent per share. Transactions in Fund shares were as follows: For the For the Six Months Ended Year Ended March 31, 2007 September 30, 2006 ---------------- ------------------ Shares sold 2,081,455 9,977,957 Shares issued to shareholders in reinvestment of distributions 2,343,003 1,232,495 Shares redeemed (2,010,181) (4,831,166) ---------- ---------- Net increase (decrease) 2,414,277 6,379,286 ========== ========== At March 31, 2007, three shareholders of record held, in the aggregate, approximately 38% of the total outstanding shares of the Fund. Investment activities of these shareholders could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that are acquired through reinvestment of distributions. For the six months ended March 31, 2007, the received $2,683 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. See the corresponding master portfolio for tax basis unrealized appreciation (depreciation) information. 11 Mellon Institutional Funds Master Portfolio The Boston Company International Small Cap Portfolio Schedule of Investments--March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Value Security Shares (Note 1A) - -------------------------------------------------------------------------------- UNAFFILIATED INVESTMENTS--98.6% COMMON EQUITIES--96.6% Australia--4.2% Australian Worldwide Exploration Ltd. 1,819,200 $ 4,192,365 Babcock & Brown Ltd. 259,600 5,766,298 Challenger Financial Services Group Ltd. 1,348,100 5,199,651 Cochlear Ltd. 84,100 4,401,171 Computershare Ltd. 438,700 3,848,851 Downer EDI Ltd. 760,100 4,191,687 Goodman Fielder Ltd. 2,568,500 5,067,609 Incitec Pivot Ltd. 147,800 5,915,798 Jubilee Mines NL 216,595 3,068,430 Pacific Brands Ltd. 1,971,800 4,894,800 Record Investments Ltd. 615,100 5,570,542 ------------ 52,117,202 ------------ Austria--1.2% Andritz AG 22,200 5,568,034 Boehler-Uddeholm 95,340 9,168,199 ------------ 14,736,233 ------------ Belgium--2.2% Colruyt SA 20,800 4,759,074 Mobistar SA 74,900 6,332,307 NV Union Miniere SA 47,860 8,507,994 Omega Pharma SA 50,200 3,865,937 Telenet Group Holding NV 133,100 4,291,328 ------------ 27,756,640 ------------ Canada--5.5% Astral Media, Inc. 143,700 5,009,953 Axcan Pharma, Inc.

The Boston Company International Small Cap Portfolio (the "Portfolio") is a separate diversified investment series of the Portfolio Trust. The objective of the Portfolio is to achieve long-term growth of capital. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of companies that are represented in the Citigroup World Extended Market Ex. U.S. (EMI Ex-U.S.) Index. At March 31, 2007, there were two funds, The Boston Company International Core Equity Fund and Dreyfus Premier International Small Cap Fund (the "Feeder Funds") invested in the Portfolio. The value of the Feeder Funds' investment in the Portfolio reflects the Feeder Funds' proportionate interests in the net assets of the Portfolio. At March 31, 2007, The Boston Company International Core Equity Fund (the "Fund") and the Dreyfus Premier International Small Cap Fund held approximately 69% and 31% interests in the Portfolio, respectively. The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities are valued at the last 2sale 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 market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Portfolio's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Portfolio'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 New York Stock Exchange ("NYSE"), the value of the Portfolio'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 Portfolio may value its assets by a method the Trustees believe accurately reflects the fair value. The Trustees have adopted fair value pricing procedures, which, among other things, require the Portfolio to fair value such securities if there has been a movement in the U.S. market that exceeds a specified threshold. Although the threshold may be revised from time to time by the Trustees 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 Portfolio 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 Portfolio acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and will then be valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity. Dividend income is recorded on ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. 24 Mellon Institutional Funds Master Portfolio The Boston Company International Small Cap Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Portfolio does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. Net realized gains and losses on foreign currency transactions represent gains and losses on disposition of foreign currencies and forward foreign currency exchange contracts, currency gains and losses realized between the trade and settlement dates on securities transactions, and the difference between the amount of investment income and foreign withholding taxes recorded on the Portfolio's books and the U.S. dollar equivalent amounts actually received or paid. C. Income taxes The Portfolio is treated as a partnership for federal tax purposes. No provision is made by the Portfolio for federal or state income taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes. Since at least one of the Portfolio's investors is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the source of income and diversification requirements applicable to regulated investment companies (under the Internal Revenue Code) in order for its investors to satisfy them. Section 988 of the Internal Revenue Code provides that gains or losses on certain transactions attributable to fluctuations in foreign currency exchange rates must be treated as ordinary income or loss. For financial statement purposes, such amounts are included in net realized gains or losses. D. Foreign currency transactions The Portfolio maintains its books and records in U.S. dollars. Investment security valuations, other assets, and liabilities initially expressed in foreign currencies are converted into U.S. dollars based upon current currency exchange rates. Purchases and sales of foreign investment securities and income and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. E. 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. F. Commitments and contingencies In the normal course of business, the Portfolio may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Portfolio under these arrangements is unknown, as this would involve future claims that may be made against the Portfolio that have not yet occurred. However, based on experience, the Portfolio expects the risks of loss to be remote. G. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among the funds of the Trust or the portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. H. Affiliated issuers Affiliated issuers are investment companies advised by The Boston Company Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. 25 Mellon Institutional Funds Master Portfolio The Boston Company International Small Cap Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- I. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The investment advisory fee paid to TBCAM for overall investment advisory, and administrative services, and general office facilities, is paid monthly at the annual rate of 1.00% of the Portfolio's average daily net assets. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Portfolio Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide custody, administration and accounting services for the Portfolio. For these services the Portfolio pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement the Portfolio was charged $358,203 for the six months ended March 31, 2007. The Portfolio Trust also entered into an agreement with Mellon Bank, to perform certain securities lending activities and to act as the Portfolio's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $46,873, for the six months ended March 31, 2007. See Note 6 for further details. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's and Portfolio Trust's Chief Compliance Officer. No other director, officer or employee of TBCAM or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust. The Fund and Portfolio Trust pays each Trustee who is not a director, officer or employee of TBCAM or its affiliates (the "Independent Trustees") an annual fee and the Portfolio Trust pays each Independent Trustee a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Portfolio Trust pays the legal fees for the counsel to the Independent Trustees. (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, 2007 were as follows: Purchases Sales ------------- ------------ Non-U.S. Government Securities $557,151,227 $603,053,522 ============= ============ 26 Mellon Institutional Funds Master Portfolio The Boston Company International Small Cap Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (4) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $966,831,332 ============ Gross unrealized appreciation 290,637,130 Gross unrealized depreciation (8,757,025) ------------ Net unrealized appreciation (depreciation) $281,880,105 ============ (5) Financial Instruments: In general, the following instruments are used for hedging purposes as described below. However, these instruments may also be used to seek to enhance potential gain in circumstances where hedging is not involved. The Portfolio may trade the following financial instruments with off-balance sheet risk: Forward currency exchange contracts The Portfolio may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Portfolio primarily to protect the value of the Portfolio's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At March 31, 2007, the Portfolio held open foreign currency exchange contracts. See Schedule of Investments for further details. Futures contracts The Portfolio may enter into financial futures contracts for the purchase or sale of securities, or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements, the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments, shown as variation margin, are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded shown as variation margin for financial statement purposes as unrealized appreciation or depreciation by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may also arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. At March 31, 2007, the Portfolio held open financial futures contracts. See Schedule of Investments for further details. 27 Mellon Institutional Funds Master Portfolio The Boston Company International Small Cap Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (6) Security Lending: The Portfolio may lend its securities to financial institutions which the Portfolio deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Portfolio on the next business day. For the duration of a loan, the Portfolio receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Portfolio bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Portfolio. In the event of borrower default, the Portfolio generally has the right to use the collateral to offset losses incurred. The Portfolio may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Portfolio also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Portfolio's obligations due on the loans. The Portfolio loaned securities for the six months ended March 31, 2007 and earned interest on the invested collateral of $129,601 of which $19,961 was rebated to borrowers or paid in fees. At March 31, 2007, the Portfolio did not have securities out for loan. (7) Line of Credit: The Portfolio, and other subtrusts in the Portfolio Trust and funds in the Trust are parties to a committed line of credit facility, which enables each portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is charged to each participating portfolio/fund based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating portfolios/funds at the end of each quarter. The participating portfolios and funds also pay an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating portfolios/funds. For the six months ended March 31, 2007, the expense allocated to the Portfolio was $1,862. The facility fee and interest expense is aggregated with miscellaneous expenses on the Statement of Operations. For the six months ended March 31, 2007, the Portfolio had average borrowings outstanding of $5,769,000 for a total of two days and incurred $1,843 of interest expense. At March 31, 2007 the Fund had no borrowings outstanding. 28 Mellon Institutional Funds Master Portfolio The Boston Company International Small Cap Portfolio Factors Considered by Board of Trustees in Approving 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. The Fund is not a party to an investment advisory agreement directly with any investment adviser and does not invest directly in portfolio securities. Instead, the Fund invests all of its investable assets in The Boston Company International Small Cap Portfolio (the "Portfolio"), which is managed by The Boston Company Asset Management LLC ("TBCAM"). The Fund's Board of Trustees determines annually whether the Fund should continue to invest in the Portfolio. The members of the Fund's Board of Trustees also serve as the Board of Trustees of the Portfolio. In that capacity, they consider annually whether to continue the investment advisory agreement between the Portfolio and TBCAM. 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 Portfolio's investment adviser, TBCAM ("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 28, 2006 to review these materials and to discuss the proposed continuation of the Fund's advisory agreement. Representatives of the Adviser attended a portion of the September meeting to provide an overview of its 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 17, 2006. 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 (rather than the Portfolio alone), 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 and Portfolio, including Portfolio'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 Portfolio and potential economies of scale; and (v) Other Benefits: The benefits flowing to Mellon Financial Corporation ("Mellon") in the form of revenues received by Mellon affiliates in consideration of custodial, administrative, transfer agency and securities lending services provided by such affiliates to the Funds. In considering the continuation of the Portfolio'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 Portfolio 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 Portfolio'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 and overall responsiveness to changes in market conditions. The Board determined that the Adviser had the expertise and resources to manage the Portfolio effectively. 29 Mellon Institutional Funds Master Portfolio The Boston Company International Small Cap Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Investment Performance The Board considered the investment performance of the Fund (rather than the Portfolio alone) 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 28, 2006 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, 2006 based on the Lipper materials provided to the Board at the September 28, 2006 meeting. The Board found that the Fund outperformed its peer group average return for the one-year period (30.46% vs. 24.07%), three-year period (35.13% vs. 29.75%) and five-year period (23.42% vs. 18.50%). Advisory Fee and Other Expenses The Board considered the advisory fee rate paid by the Portfolio to the Adviser. The Lipper data presenting the Portfolio's "net management fees" included fees paid by the Portfolio, as calculated by Lipper, for administrative services provided by Mellon Bank, N.A., the Portfolio's custodian. Such reporting was necessary, according to Lipper, to allow the Board to compare the Portfolio's advisory fees to those peers that include administrative fees within a blended advisory fee. The Portfolio's contractual advisory fee was 1.00%, in the 3rd quintile (1st being the best) of its peer group of funds, the median fee of which was 0.984%. The Portfolio's net management fee was 1.088% (which included 0.091% in administrative services fees under Lipper's calculation methodology), higher than the peer group median net management fee of 0.970%. Based on the Lipper data, as well as other factors discussed at the September 28, 2006 meeting, the Board determined that the Portfolio's advisory fee is reasonable relative to its peer group averages. The Board also compared the fees payable by the Portfolio 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 Portfolio 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 (rather than solely the Portfolio'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 1.160% was lower than the median net expense ratio of the peer group of 1.294%, 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 Portfolio and 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 adviser, Standish Mellon Asset Management Company LLC ("Standish Mellon") in managing the Portfolio and other funds in the Mellon Institutional Funds family of funds. The Independent Trustees had observed that the Adviser, based on profitability information submitted to them by the Adviser, incurred marginal profitability in managing most of the investment companies in the Mellon Institutional Funds family of funds. The Trustees observed that the Adviser had experienced profits in operating the Portfolio in both 2004 and 2005 and concluded these were not excessive. 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 Boston Company International Core Equity Portfolio and the Standish Mellon Fixed Income Portfolio, 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. 30 Mellon Institutional Funds Master Portfolio The Boston Company International Small Cap Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Other Benefits The Board also considered the additional benefits flowing to Mellon as a result of its relationship with the Mellon Institutional Funds as a group, including revenues received by 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 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 Portfolio'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. 31 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

Mellon Institutional Funds Investment Trust The Boston Company Large Cap Core 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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ------------------------------------------------------------------------------------------------------------------------------ Actual $1,000.00 $1,092.40 $4.28 Hypothetical (5% return per year before expenses) $1,000.00 $1,020.84 $4.13 - ---------- + Expenses are equal to the Fund's annualized expense ratio of 0.82%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).The example reflects the combined expenses of the Fund and the master portfolio in which it invests all its assets. 3 Mellon Institutional Funds Investment Trust The Boston Company Large Cap Core Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- The Boston Company Large Cap Core Fund invests all of its investable assets in an interest of The Boston Company Large Cap Core Portfolio (See Note 1 of the Fund's Notes to Financial Statements).

The Boston Company Large Cap Core Fund (the "Fund") is a separate diversified investment series of the Trust. The objective of the Fund is to achieve long-term growth of capital. The Fund invests all of its investable assets in an interest of The Boston Company Large Cap Core Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust, and which has the same investment objective as the Fund. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities in companies that appear to be undervalued relative to underlying business fundamentals. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. As of March 31, 2007 the Fund owned 100% of the Portfolio's net assets. The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations 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. The Fund records its investments in the Portfolio at value. The Portfolio values its securities at value as discussed in Note 1A of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. B. Securities transactions and income The Fund's investment in the Portfolio is recorded on settlement date. The Portfolio's securities transactions are recorded as of the trade date as discussed in Note 1B of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. All realized and unrealized gains and losses of the Fund represent pro rata shares of gains and losses of the Portfolio. 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 are declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for losses deferred due to wash sales and unrealized gains or losses on futures contracts. Permanent book and tax basis differences relating to shareholder distributions result in reclassifications among undistributed net investment income(loss), accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (loss) and accumulated net realized gain (loss) on investments may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. D. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust and/or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. 9 Mellon Institutional Funds Investment Trust The Boston Company Large Cap Core Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The Fund does not directly pay any investment advisory fees, but indirectly bears its pro rata share of the compensation paid by the Portfolio to The Boston Company Asset Management, LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, for such services. See Note 2 of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $5,485 for the six months ended March 31, 2007. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $978, which 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 Portfolio Trust 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. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $400, which is included in miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. The Fund pays 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, 2007, the Fund was charged $66,830 for fees payable to Mellon Private Wealth Management. 10 Mellon Institutional Funds Investment Trust The Boston Company Large Cap Core Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended March 31, 2007 aggregated $33,403,101 and $20,409,175, respectively. The Fund receives a proportionate share of the Portfolio's income, expense and realized and unrealized gains and losses based on applicable tax allocation rules. Book/tax differences arise when changes in proportionate interest for funds investing in the Portfolio occur. (4) Shares of Beneficial Interest: The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest having a par value of one cent per share. Transactions in Fund shares were as follows: For the For the Six Months Ended Year Ended March 31, 2007 September 30, 2006 ---------------- ------------------ Shares sold 748,800 1,384,404 Shares issued to shareholders in reinvestment of distributions 100,435 146,598 Shares redeemed (403,670) (199,694) ------- --------- Net increase (decrease) 445,565 1,331,308 ======= ========= At March 31, 2007, two shareholders of record held, in the aggregate, approximately 72% of the total outstanding shares of the Fund. Investment activities of these shareholders could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that are acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund did not assess any redemption fees. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. See the corresponding master portfolio for tax basis unrealized appreciation (depreciation) information. 11 Mellon Institutional Funds Master Portfolio The Boston Company Large Cap Core Portfolio Schedule of Investments--March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Value Security Shares (Note 1A) - ----------------------------------------------------------------------------------------------------- UNAFFILIATED INVESTMENT--98.7% EQUITIES--98.7% Consumer Discretionary--8.4% Coach, Inc.

The Boston Company Large Cap Core Portfolio (the "Portfolio") is a separate diversified investment series of the Portfolio Trust. The objective of the Portfolio is long-term growth of capital. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of companies that appear to be undervalued relative to underlying business fundamentals. At March 31, 2007, there was one fund, The Boston Company Large Cap Core Fund (the "Fund"), invested in the Portfolio. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. The Fund's proportionate interest at March 31, 2007 was 100%. The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities 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 market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Portfolio's assets that are invested in one or more open open-ended regulated investment companies ("RICs"), the Portfolio'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. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Portfolio acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity. Dividend income is recorded on ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. C. Income taxes Each Portfolio is treated as a disregarded entity for U.S. federal income tax purposes and consequently, each corresponding Feeder Fund that invests in a Portfolio is treated for U.S. federal income tax purposes as owning all of the underlying assets of such Portfolio. No provision is made by the Portfolio for federal or state income taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes. Since the Portfolio's investor is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the source of income and diversification requirements applicable to regulated investment companies (under the Internal Revenue Code) in order for its investors to satisfy them. 19 Mellon Institutional Funds Master Portfolio The Boston Company Large Cap Core Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- D. Commitments and contingencies In the normal course of business, the Portfolio may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Portfolio under these arrangements is unknown, as this would involve future claims that may be made against the Portfolio that have not yet occurred. However, based on experience, the Portfolio expects the risks of loss to be remote. E. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. F. Affiliated issuers Affiliated issuers are investment companies advised by The Boston Company Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. G. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to TBCAM for overall investment advisory and administrative services and general office facilities is paid monthly at the annual rate of 0.50% of the Portfolio's average daily net assets On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Portfolio Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide custody, administration and accounting services for the Portfolio. For these services the Portfolio pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Portfolio was charged $52,781 for the six months ended March 31, 2007. The Portfolio Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Portfolio's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank did not earn any revenues for the six months ended March 31, 2007. See Note 6 for further details. 20 Mellon Institutional Funds Master Portfolio The Boston Company Large Cap Core Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's and Portfolio Trust's Chief Compliance Officer. No other director, officer or employee of TBCAM or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust or Portfolio Trust. The Fund and Portfolio Trust pays each Trustee who is not a director, officer or employee of TBCAM or its affiliates (the "Independent Trustees") an annual fee and the Portfolio Trust pays each Independent Trustee a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Portfolio Trust pays the legal fees for the counsel to the Independent Trustees. (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, 2007 were as follows: Purchases Sales ------------ -------------- Non-U.S. Government Securities $ 50,738,626 $ 35,561,263 (4) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $106,579,246 ------------ Gross unrealized appreciation 10,736,182 Gross unrealized depreciation (1,214,414) ------------ Net unrealized appreciation (depreciation) $ 9,521,768 ============ (5) Financial Instruments: In general, the following instruments are used for hedging purposes as described below. However, these instruments may also be used to seek to enhance potential gain in circumstances where hedging is not involved. The Portfolio may trade the following financial instruments with off-balance sheet risk: Futures contracts The Portfolio may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments, known as variation margin, are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized appreciation or depreciation by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. At March 31, 2007, the Portfolio did not hold open financial futures contracts. 21 Mellon Institutional Funds Master Portfolio The Boston Company Large Cap Core Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (6) Security Lending: The Portfolio may lend its securities to financial institutions which the Portfolio deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Portfolio on the next business day. For the duration of a loan, the Portfolio receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Portfolio bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Portfolio. In the event of borrower default, the Portfolio generally has the right to use the collateral to offset losses incurred. The Portfolio may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Portfolio also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Portfolio's obligations due on the loans. The Portfolio did not loan securities for the six months ended March 31, 2007. (7) Line of Credit: The Portfolio, and other subtrusts in the Portfolio Trust and funds in the Trust are parties to a committed line of credit facility, which enables each portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is charged to each participating portfolio/fund based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating portfolios/funds at the end of each quarter. The participating portfolios and funds also pay an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating portfolio/fund. For the six months ended March 31, 2007, the expense allocated to the Portfolio was $629. The commitment fee and interest expense is aggregated with miscellaneous expenses on the Statement of Operations. For the six months ended March 31, 2007, the Portfolio had average borrowings outstanding of $1,299,000 for a total of thirteen days and incurred $2,719 of interest expense. At March 31, 2007 the Portfolio had no borrowings outstanding. 22 Mellon Institutional Funds Master Portfolio The Boston Company Large Cap Core Portfolio Factors Considered by Board of Trustees in Approving 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. The Fund is not a party to an investment advisory agreement directly with any investment adviser and does not invest directly in portfolio securities. Instead, the Fund invests all of its investable assets in The Boston Company Large Cap Core Portfolio (the "Portfolio"), which is managed by The Boston Company Asset Management LLC ("TBCAM"). The Fund's Board of Trustees determines annually whether the Fund should continue to invest in the Portfolio. The members of the Fund's Board of Trustees also serve as the Board of Trustees of the Portfolio. In that capacity, they consider annually whether to continue the investment advisory agreement between the Portfolio and TBCAM. 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 Portfolio's investment adviser, TBCAM ("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 28, 2006 to review these materials and to discuss the proposed continuation of the Fund's advisory agreement. Representatives of the Adviser attended a portion of the September meeting to provide an overview of its 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 17, 2006. 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 (rather than the Portfolio alone), 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 and Portfolio, including Portfolio'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 Portfolio and potential economies of scale; and (v) Other Benefits: The benefits flowing to Mellon Financial Corporation ("Mellon") in the form of revenues received by Mellon affiliates in consideration of custodial, administrative, transfer agency and securities lending services provided by such affiliates to the Funds. In considering the continuation of the Portfolio'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 Portfolio 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 Portfolio'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 and overall responsiveness to changes in market conditions. The Board determined that the Adviser had the expertise and resources to manage the Portfolio effectively. 23 Mellon Institutional Funds Master Portfolio The Boston Company Large Cap Core Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Investment Performance The Board considered the investment performance of the Fund (rather than the Portfolio alone) 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 28, 2006 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, 2006 based on the Lipper materials provided to the Board at the September 28, 2006 meeting. The Board found that the Fund outperformed its peer group average return for the one-year period (6.14% vs. 4.79%), three-year period (10.86% vs. 10.59%) and five-year period (3.98% vs. 2.44%). Advisory Fee and Other Expenses The Board considered the advisory fee rate paid by the Portfolio to the Adviser. The Lipper data presenting the Portfolio's "net management fees" included fees paid by the Portfolio, as calculated by Lipper, for administrative services provided by Mellon Bank, N.A., the Portfolio's custodian. Such reporting was necessary, according to Lipper, to allow the Board to compare the Portfolio's advisory fees to those peers that include administrative fees within a blended advisory fee. The Portfolio's contractual advisory fee was 0.500%, in the 1st (best) quintile of its peer group of funds, the median fee of which was 0.725%. The Portfolio's net management fee was 0.637% (which included 0.137% in administrative services fees under Lipper's calculation methodology), lower than the peer group median net management fee of 0.670%. Based on the Lipper data, as well as other factors discussed at the September 28, 2006 meeting, the Board determined that the Portfolio's advisory fee is reasonable relative to its peer group averages. The Board also compared the fees payable by the Portfolio 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 Portfolio 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 (rather than solely the Portfolio'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 0.849% was lower than the median net expense ratio of the peer group of 0.868%, 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 Portfolio and 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 adviser, Standish Mellon Asset Management Company LLC ("Standish Mellon") in managing the Portfolio and other funds in the Mellon Institutional Funds family of funds. The Independent Trustees had observed that the Adviser, based on profitability information submitted to them by the Adviser, incurred marginal profitability in managing most the investment companies in the Mellon Institutional Funds family of funds. The Trustees observed that the Adviser had incurred a loss in operating the Portfolio in 2004 and had experienced a profit in operating the Portfolio in 2005 and concluded the profit was not excessive. 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 Boston Company International Core Equity Portfolio and the Standish Mellon Fixed Income Portfolio, 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. 24 Mellon Institutional Funds Master Portfolio The Boston Company Large Cap Core Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Other Benefits The Board also considered the additional benefits flowing to Mellon as a result of its relationship with the Mellon Institutional Funds as a group, including revenues received by 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 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 Portfolio'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. 25 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - -------------------------------------------------------------------------------------- Actual $1,000.00 $1,117.20 $5.28 Hypothetical (5% return per year before expenses) $1,000.00 $1,019.95 $5.04 - --------- + Expenses are equal to the Fund's annualized expense ratio of 1.00%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). 3 Mellon Institutional Funds Investment Trust The Boston Company Small/Mid Cap Growth Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Holdings* Sector Investments - ----------------------------------------------------------------------------- Washington Group International Industrials 1.6% Stericycle, Inc.

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 market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Fund's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. Exchange traded options and futures are valued at the settlement price determined by the relevant exchange. 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 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 differing treatments for losses deferred due to wash sales and the timing of recognition of realized and unrealized gains or 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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. 13 Mellon Institutional Funds Investment Trust The Boston Company Small/Mid Cap Growth Fund 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 Mellon Financial Corporation, or its affiliates. G. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The investment advisory fee paid to TBCAM for overall investment advisory, administrative services, and general office facilities, is paid monthly at the annual rate of 0.60% of the Fund's average daily net assets. TBCAM voluntarily agreed to limit the Fund's total annual operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 1.00% of the Fund's average daily net assets for the six months ended March 31, 2007. Pursuant to this arrangement, for the six months ended March 31, 2007, TBCAM voluntarily reimbursed $30,086 of the Fund's operating expenses. This arrangement is voluntary and temporary and may be discontinued or revised by TBCAM at any time. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as, out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $3,977 for the six months ended March 31, 2007. The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation 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 $31,576 for the six months ended March 31, 2007. 14 Mellon Institutional Funds Investment Trust The Boston Company Small/Mid Cap Growth Fund 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 $815 for the six months ended March 31, 2007. See Note 7 for further details. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,105, which 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 Mellon Financial Corporation and an affiliate of TBCAM, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $317, which is included in miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. The Fund pays 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. (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, 2007 were as follows: Purchases Sales --------- ----- Non-U.S. Government Securities $18,613,594 $18,133,858 =========== ============ (4) Shares of Beneficial Interest: The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest having a par value of one cent per share. Transactions in Fund shares were as follows: For the For the Six Months Ended Year Ended March 31, 2007 September 30, 2006 ---------------- ------------------ Shares sold 114,744 6,818 Shares issued to shareholders in reinvestment of distributions 84,274 - Shares redeemed (118,539) (64,826) ----------- ------- Net increase (decrease) 80,479 (58,008) =========== ======= At March 31, 2007, two shareholders of record held, in the aggregate, approximately 78% of the total outstanding shares of the Fund. Investment activities of these shareholders could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund did not access any redemption fees. 15 Mellon Institutional Funds Investment Trust The Boston Company Small/Mid Cap Growth Fund 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 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. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $24,224,243 =========== Gross unrealized appreciation $ 2,035,318 Gross unrealized depreciation (257,038) ----------- Net unrealized appreciation (depreciation) $ 1,778,280 =========== (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, known as variation margin, 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, 2007, the Fund held open financial futures contracts. See the Schedule of Investments for further details. (7) Security Lending: The Fund may lend its securities to financial institutions which the Fund deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Fund on the next business day. For the duration of a loan, the Fund receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Fund bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Fund. In the event of borrower default, the Fund generally has the right to use the collateral to offset losses incurred. The Fund may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Fund also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Fund's obligations due on the loans. The Fund loaned securities during the six months ended March 31, 2007 and earned interest on the invested collateral of $31,783 of which $29,850 was rebated to borrowers or paid in fees. At March 31, 2007, the Fund had securities valued at $1,932,390 on loan. See Schedule of Investments for further detail on the security positions on loan and collateral held. 16 Mellon Institutional Funds Investment Trust The Boston Company Small/Mid Cap Growth Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (8) Line of Credit: The Fund, and other funds in the Trust and subtrusts in Mellon Institutional Funds Master Portfolio (the"Portfolio Trust") are parties to a committed line of credit facility, which enables each fund/portfolio to borrow, in the aggregate, up to $35 million. Interest is charged to each participating fund/portfolio based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating funds/portfolios at the end of each quarter. Each fund/portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating funds/portfolios. For the six months ended March 31, 2007, the expense allocated to the Fund was $408. The facility fee and interest expense are included in miscellaneous expenses on the statement of operations. For the six months ended March 31, 2007, the Fund had average borrowings outstanding of $1,200,000 for a total of four days and incurred $767 of interest expense. At March 31, 2007 the Fund had no borrowings outstanding. 17 Mellon Institutional Funds Investment Trust The Boston Company Small/Mid Cap Growth Fund Factors Considered by Board of Trustees in Approving 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 28, 2006 to review these materials and to discuss the proposed continuation of the Fund's advisory agreement. Representatives of the Adviser attended a portion of the September meeting to provide an overview of its 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 17, 2006. 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 Mellon Financial Corporation ("Mellon") in the form of revenues received by Mellon affiliates in consideration of custodial, administrative, transfer agency and securities lending services provided by such affiliates to the Funds. 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 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 for at the September 28, 2006 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, 2006 based on the Lipper materials provided to the Board at the September 28, 2006 meeting. The Board found that the Fund outperformed its peer group average returns for the one-year period (5.34% vs. 4.35%), three-year period (16.53% vs. 12.96%) and five-year period (7.12% vs. 5.32%). 18 Mellon Institutional Funds Investment Trust The Boston Company Small/Mid Cap Growth Fund Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Advisory Fee and Other Expenses The Board considered the advisory fee rate paid by the Fund to the Adviser. The Fund's contractual advisory fee was 0.600%, in the 1st (best) quintile of its peer group of funds, the median fee of which was 0.775%. The Fund's net management fee, after giving effect to expense limitations, was 0.220%, below the peer group median net management fee of 0.663%. Based on the Lipper data, as well as other factors discussed at the September 28, 2006 meeting, the Board determined that the Fund's advisory fee is reasonable relative to its peer group averages, both with and without giving effect to expense limitations. 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 1.002% (after giving effect to expense limitations) was slightly higher than the median net expense ratio of the peer group of 0.984%. However, most of the 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 adviser, Standish Mellon Asset Management Company LLC ("Standish Mellon") 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 profitability information submitted to them by the Adviser, incurred marginal profitability in managing most 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 both 2004 and 2005. 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 Boston Company International Core Equity Portfolio and the Standish Mellon Fixed Income Portfolio and, 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 assets 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 Mellon as a result of its relationship with the Mellon Institutional Funds as a group, including revenues received by 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 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 the Adviser provided therein are fair and reasonable and, thus, in approving the continuation of the agreement for a one-year period. 19 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

Mellon Institutional Funds Investment Trust The Boston Company Small 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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ------------------------------------------------------------------------------------------------ Actual $1,000.00 $1,101.70 $5.71 Hypothetical (5% return per year before expenses) $1,000.00 $1,019.50 $5.49 - ----------- + Expenses are equal to the Fund's annualized expense ratio of 1.09%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). The example reflects the combined expenses of the Fund and the master portfolio in which it invests all its assets. 3 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Growth Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- The Boston Company Small Cap Growth Fund invests all of its investable assets in an interest ofThe Boston Company Small Cap Growth Portfolio (see Note 1 of the Fund's Notes to Financial Statements).

The Boston Company Small Cap Growth Fund (the "Fund") is a separate diversified investment series of the Trust. The objective of the Fund is to achieve long-term growth of capital. The Fund invests all of its investable assets in an interest of The Boston Company Small Cap Growth Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust, and has the same investment objective as the Fund. The Portfolio seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in equity securities of small cap U.S. companies. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. As of March 31, 2007 the Fund owned 100% of the Portfolio's net assets. The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations 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. The Fund records its investments in the Portfolio at value. The Portfolio values its securities at value as discussed in Note 1A of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. B. Securities transactions and income The Fund's investment in the Portfolio is recorded on settlement date. The Portfolio's securities transactions are recorded as of the trade date as discussed in Note 1B of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. All realized and unrealized gains and losses of the Fund represent pro rata shares of gains and losses of the Portfolio. 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 are declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for losses deferred due to wash sales, capital loss carryovers and the timing of recognition of realized and unrealized gains or 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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. D. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust and/or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. 9 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Growth Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The Fund does not directly pay any investment advisory fees, but indirectly bears its pro rata share of the compensation paid by the Portfolio to The Boston Company Asset Management, LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, for such services. See Note 2 of the Portfolio's Notes to Financial Statements which are included elsewhere in this report. TBCAM voluntarily agreed to limit the total annual operating expenses of the Fund and its pro rata share of the Portfolio expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 1.10% of the Fund's average daily net assets. This agreement is voluntary and temporary and may be discontinued or revised by TBCAM at any time. Pursuant to this agreement, for the six months ended March 31, 2007, TBCAM voluntary reimbursed $47,925 of the Fund's operating expenses. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $5,992 for the six months ended March 31, 2007. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,126, which 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 Portfolio Trust 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. The Fund pays 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, 2007, the Fund was charged $7,803 for fees payable to Mellon Private Wealth Management. 10 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Growth Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended March 31, 2007 aggregated $49,533,053 and $5,169,458, respectively. The Fund receives a proportionate share of the Portfolio's income, expense and realized and unrealized gains and losses based on applicable tax allocation rules. Book/tax differences arise when changes in proportionate interest for funds investing in the Portfolio occur. (4) Shares of Beneficial Interest: The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest having a par value of one cent per share. Transactions in Fund shares were as follows: For the For the Six Months Ended Year Ended March 31, 2007 September 30, 2006 Shares sold 952,540 237,244 Shares redeemed (96,837) (174,108) ------- -------- Net increase (decrease) 855,703 63,136 ======= ======== At March 31, 2007, three shareholders of record held, in the aggregate, approximately 42% of the total outstanding shares of the Fund. Investment activities of these shareholders could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that are acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund received $330 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.

The Boston Company Small Cap Growth Portfolio (the "Portfolio") is a separate diversified investment series of the Portfolio Trust. The objective of the Portfolio is to achieve long-term growth of capital. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of its net assets in equity securities of small cap U.S. companies. At March 31, 2007, there was one Fund, The Boston Company Small Cap Growth Fund (the "Fund") invested in the Portfolio. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. The Fund's proportionate interest at March 31, 2007 was 100%. The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities 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 market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Portfolio's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Portfolio'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. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Portfolio acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity. Dividend income is recorded on ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. C. Income taxes Each Portfolio is treated as a disregarded entity for U.S. federal income tax purposes and consequently, each corresponding Feeder Fund that invests in a Portfolio is treated for U.S. federal income tax purposes as owning all of the underlying assets of such Portfolio. No provision is made by the Portfolio for federal or state income taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes. Since the Portfolio's investor is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the source of income and diversification requirements applicable to regulated investment companies (under the Internal Revenue Code) in order for its investors to satisfy them. 21 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Growth Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- D. Commitments and contingencies In the normal course of business, the Portfolio may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Portfolio under these arrangements is unknown, as this would involve future claims that may be made against the Portfolio that have not yet occurred. However, based on experience, the Portfolio expects the risks of loss to be remote. E. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. F. Affiliated issuers Affiliated issuers represent issuers in which the Portfolio held investments in other investment companies advised by The Boston Company Asset Management, LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. G. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to TBCAM for overall investment advisory and administrative services and general office facilities is paid monthly at the annual rate of 0.80% of the Portfolio's average daily net assets. TBCAM voluntarily agreed to limit the total annual operating expenses of the Fund and its pro rata share of the Portfolio expenses (excluding brokerage commission, taxes and extraordinary expense) to 1.10% of the Fund's average daily net assets. This agreement is voluntary and temporary and may be discontinued or revised by TBCAM at any time. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Portfolio Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide custody, administration and accounting services for the Portfolio. For these services the Portfolio pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Portfolio was charged $50,656 for the six months ended March 31, 2007. The Portfolio Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Portfolio's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $9,403 for the six months ended March 31, 2007. See Note 6 for further details. 22 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Growth Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's and Portfolio Trust's Chief Compliance Officer. No other director, officer or employee of TBCAM or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust or Portfolio Trust. The Fund and Portfolio Trust pays each Trustee who is not a director, officer or employee of TBCAM or its affiliates (the "Independent Trustees") an annual fee and the Portfolio Trust pays each Independent Trustee a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Portfolio Trust pays the legal fees for the counsel to the Independent Trustees. (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, 2007 were as follows: Purchases Sales ----------- ----------- Non-U.S. Government Securities $80,431,665 $40,600,585 =========== =========== (4) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $114,752,526 ------------ Gross unrealized appreciation 5,915,487 Gross unrealized depreciation (1,334,598) ------------ Net unrealized appreciation (depreciation) $4,580,889 ============ (5) Financial Instruments: In general, the following instruments are used for hedging purposes as described below. However, these instruments may also be used to seek to enhance potential gain in circumstances where hedging is not involved. The Portfolio may trade the following financial instruments with off-balance sheet risk: Futures contracts The Portfolio may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments, known as variation margin, are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized appreciation or depreciation by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. At March 31, 2007, the Portfolio held open financial futures contracts. See Schedule of Investments for further details. 23 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Growth Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (6) Security Lending: The Portfolio may lend its securities to financial institutions which the Portfolio deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Portfolio on the next business day. For the duration of a loan, the Portfolio receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Portfolio bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Portfolio. In the event of borrower default, the Portfolio generally has the right to use the collateral to offset losses incurred. The Portfolio may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Portfolio also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Portfolio's obligations due on the loans. The Portfolio loaned securities for the six months ended March 31, 2007 and earned interest on the invested collateral of $198,509 of which, $176,633 was rebated to borrowers or paid in fees. At March 31, 2007, the Portfolio had securities valued at $18,384,804 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. (7) Line of Credit: The Portfolio, and other subtrusts in the Portfolio Trust and funds in the Trust are parties to a committed line of credit facility, which enables each portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is charged to each participating portfolio/fund based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating portfolios/funds at the end of each quarter. The participating portfolios and funds also pay an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating portfolios/funds. For the six months ended March 31, 2007, the expense allocated to the Portfolio was $54. The commitment fee and interest expense is aggregated with miscellaneous expenses on the Statement of Operations. For the six months ended March 31, 2007, the Portfolio did not borrow from the line of credit. 24 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Growth Portfolio Factors Considered by Board of Trustees in Approving 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. The Fund is not a party to an investment advisory agreement directly with any investment adviser and does not invest directly in portfolio securities. Instead, the Fund invests all of its investable assets in The Boston Company Small Cap Growth Portfolio (the "Portfolio"), which is managed by The Boston Company Asset Management LLC ("TBCAM"). The Fund's Board of Trustees determines annually whether the Fund should continue to invest in the Portfolio. The members of the Fund's Board of Trustees also serve as the Board of Trustees of the Portfolio. In that capacity, they consider annually whether to continue the investment advisory agreement between the Portfolio and TBCAM. 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 Portfolio's investment adviser, TBCAM ("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 28, 2006 to review these materials and to discuss the proposed continuation of the Fund's advisory agreement. Representatives of the Adviser attended a portion of the September meeting to provide an overview of its 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 17, 2006. 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 (rather than the Portfolio alone), 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 and Portfolio, including Portfolio'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 Portfolio and potential economies of scale; and (v) Other Benefits: The benefits flowing to Mellon Financial Corporation ("Mellon") in the form of revenues received by Mellon affiliates in consideration of custodial, administrative, transfer agency and securities lending services provided by such affiliates to the Funds. In considering the continuation of the Portfolio'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 Portfolio 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 Portfolio'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 and overall responsiveness to changes in market conditions. The Board determined that the Adviser had the expertise and resources to manage the Portfolio effectively. 25 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Growth Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Investment Performance The Board considered the investment performance of the Fund (rather than the Portfolio alone) 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 28, 2006 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, 2006 based on the Lipper materials provided to the Board at the September 28, 2006 meeting. The Board found that the Fund outperformed its peer group average return for the one-year period (3.86% vs. 1.11%) and three-year period (14.81% vs. 12.98%) and had underperformed its peer group average return for the five-year period (5.31% vs. 5.71%). Advisory Fee and Other Expenses The Board considered the advisory fee rate paid by the Portfolio to the Adviser. The Lipper data presenting the Portfolio's "net management fees" included fees paid by the Portfolio, as calculated by Lipper, for administrative services provided by Mellon Bank, N.A., the Portfolio's custodian. Such reporting was necessary, according to Lipper, to allow the Board to compare the Portfolio's advisory fees to those peers that include administrative fees within a blended advisory fee. The Portfolio's contractual advisory fee was 0.800%, in the 2nd quintile (1st being the best) of its peer group of funds, the median fee of which was 0.900%. The Portfolio's net management fee, after giving effect to expense limitations, was 0.789% (which included 0.227% in administrative services fees under Lipper's calculation methodology), lower than the peer group median net management fee of 0.860%. Based on the Lipper data, as well as other factors discussed at the September 28, 2006 meeting, the Board determined that the Portfolio's advisory fee is reasonable relative to its peer group averages. The Board also compared the fees payable by the Portfolio 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 Portfolio 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 (rather than solely the Portfolio'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 1.163% (after giving effect to expense limitations) was higher than the median net expense ratio of the peer group of 1.104%. However, 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 Portfolio and 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 adviser, Standish Mellon Asset Management Company LLC ("Standish Mellon") in managing the Portfolio and other funds in the Mellon Institutional Funds family of funds. The Independent Trustees had observed that the Adviser, based on profitability information submitted to them by the Adviser, incurred marginal profitability in managing most 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 Portfolio in 2004 and 2005. 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 Boston Company International Core Equity Portfolio and the Standish Mellon Fixed Income Portfolio, 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. 26 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Growth Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Other Benefits The Board also considered the additional benefits flowing to Mellon as a result of its relationship with the Mellon Institutional Funds as a group, including revenues received by 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 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 Portfolio'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. 27 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - -------------------------------------------------------------------------------------- Actual $1,000.00 $1,104.30 $5.19 Hypothetical (5% return per year before expenses) $1,000.00 $1,020.00 $4.99 - ----------- + Expenses are equal to the Fund's annualized expense ratio of 0.99%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). 3 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Tax-Sensitive Equity Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Holdings* Sector Investments - -------------------------------------------------------------------------------------------- Washington Group International, Inc.

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 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 market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Fund's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. 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 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 differing treatments for losses deferred due to wash sales and the timing of recognition of realized and unrealized gains or 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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. D. Expenses The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated 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. 14 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Tax-Sensitive Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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 Mellon Financial Corporation, or its affiliates. G. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The investment advisory fee paid to TBCAM for overall investment advisory and administrative services, and general office facilities, is paid monthly at the annual rate of 0.80% of the Fund's average daily net assets. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as, out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $6,844 for the six months ended March 31, 2007. The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation 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 $72,313 for the six months ended March 31, 2007. The Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Fund's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $33,907 for the six months ended March 31, 2007. See Note 7 for further details. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,105. 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. 15 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Tax-Sensitive Equity Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $2,000, which is included in miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. The Fund pays 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, 2007, the Fund was charged $29,590 for fees payable to Mellon Private Wealth Management. (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, 2007 were as follows: Purchases Sales --------- ----- Non-U.S. Government Securities $149,861,242 $132,317,244 ============ ============ (4) Shares of Beneficial Interest: The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest having a par value of one cent per share. Transactions in Fund shares were as follows: For the For the Six Months Ended Year Ended March 31, 2007 September 30, 2006 -------------- ------------------ Shares sold 657,359 604,209 Shares issued to shareholders in reinvestment of distributions 659,528 244,757 Shares redeemed (358,779) (829,484) -------- -------- Net increase (decrease) 958,108 19,482 ======== ======== At March 31, 2007, one shareholder of record held, in the aggregate, approximately 66% of the total outstanding shares of the Fund. Investment activities of this shareholder could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund did not assess any redemption fees. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $ 226,837,968 ------------- Gross unrealized appreciation 25,579,717 Gross unrealized depreciation (2,282,611) ------------- Net unrealized appreciation (depreciation) $ 23,297,106 ============= 16 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Tax-Sensitive Equity Fund 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: 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, known as variation margin, 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, 2007, the Fund held open financial futures contracts. See the Schedule of Investments for further details. (7) Security Lending: The Fund may lend its securities to financial institutions which the Fund deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Fund on the next business day. For the duration of a loan, the Fund receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Fund bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Fund. In the event of borrower default, the Fund generally has the right to use the collateral to offset losses incurred. The Fund may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Fund also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Fund's obligations due on the loans. The Fund loaned securities during the six months ended March 31, 2007 and earned interest on the invested collateral of $787,601 of which $707,644 was rebated to borrowers or paid in fees. At March 31, 2007, the Fund had securities valued at $44,762,192 on loan. See Schedule of Investments for further detail on the security positions on loan and collateral held. (8) Line of Credit: The Fund, and other funds in the Trust and subtrusts in Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") are parties to a committed line of credit facility, which enables each fund/portfolio to borrow, in the aggregate, up to $35 million. Interest is charged to each participating fund/portfolio based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating funds/portfolios at the end of each quarter. Each fund/portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating funds/portfolios. For the six months ended March 31, 2007, the expense allocated to the Fund was $191. The facility fee and interest expense are included in miscellaneous expenses on the statement of operations. For the six months ended March 31, 2007, the Fund did not have any borrowings outstanding. 17 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Tax-Sensitive Equity Fund Factors Considered by Board of Trustees in Approving 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 28, 2006 to review these materials and to discuss the proposed continuation of the Fund's advisory agreement. Representatives of the Adviser attended a portion of the September meeting to provide an overview of its 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 17, 2006. 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 Mellon Financial Corporation ("Mellon") in the form of revenues received by Mellon affiliates in consideration of custodial, administrative, transfer agency and securities lending services provided by such affiliates to the Funds. 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 and overall responsiveness to changes in market conditions. The Board determined that the Adviser had the expertise and resources to manage the Fund effectively. 18 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Tax-Sensitive Equity Fund Factors Considered by Board of Trustees in Approving 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 for at the September 28, 2006 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, 2006 based on the Lipper materials provided to the Board at the September 28, 2006 meeting. The Board found that the Fund outperformed its peer group average returns for the one-year period (4.12% vs. 1.09%), three-year period (15.25% vs. 13.21%) and five-year period (6.00% vs. 5.95%). Advisory Fee and Other Expenses The Board considered the advisory fee rate paid by the Fund to the Adviser. The Fund's contractual advisory fee was 0.800%, in the 2nd quintile (1st being the best) of its peer group of funds, the median fee of which was 0.900%. The Fund's net management fee, after giving effect to expense limitations, was 0.799%, below the peer group median net management fee of 0.860%. Based on the Lipper data, as well as other factors discussed at the September 28, 2006 meeting, the Board determined that the Fund's advisory fee is reasonable relative to its peer group averages, both with and without giving effect to expense limitations. 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 0.990% was lower than the median net expense ratio of the peer group of 1.104%, 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 adviser, Standish Mellon Asset Management Company LLC ("Standish Mellon") 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 profitability information submitted to them by the Adviser, incurred marginal profitability in managing most of the investment companies in the Mellon Institutional Funds family of funds. The Trustees observed that the Adviser had experienced profits in operating the Fund in both 2004 and 2005 and concluded these were not excessive. 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 Boston Company International Core Equity Portfolio and the Standish Mellon Fixed Income Portfolio and, 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 assets growth projections, the implementation of additional fee breakpoints or other fee reductions was not necessary at this time. 19 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Tax-Sensitive Equity Fund Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Other Benefits The Board also considered the additional benefits flowing to Mellon as a result of its relationship with the Mellon Institutional Funds as a group, including revenues received by 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 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 the Adviser provided therein are fair and reasonable and, thus, in approving the continuation of the agreement for a one-year period. 20 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

Mellon Institutional Funds Investment Trust 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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ------------------------------------------------------------------------------------- Actual $1,000.00 $1,122.10 $4.76 Hypothetical (5% return per year before expenses) $1,000.00 $1,020.44 $4.53 - -------- + Expenses are equal to the Fund's annualized expense ratio of 0.90%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). The example reflects the combined expenses of the Fund and the master portfolio in which it invests all its assets. 3 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Value Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- The Boston Company Small Cap Value Fund invests all of its investable assets in an interest of The Boston Company Small Cap Value Portfolio (See Note 1 of the Fund's Notes to Financial Statements).

The Boston Company Small Cap Value Fund (the "Fund") is a separate diversified investment series of the Trust. The Fund invests all of its investable assets in an interest of The Boston Company Small Cap Value Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust, and has the same investment objective as the Fund. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of small cap U.S. companies. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. As of March 31, 2007, the Fund owned 91% of the Portfolio's net assets. The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations 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. The Fund records its investments in the Portfolio at value. The Portfolio values its securities at value as discussed in Note 1A of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. B. Securities transactions and income The Fund's investment in the Portfolio is recorded on settlement date. The Portfolio's securities transactions are recorded as of the trade date as discussed in Note 1B of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. All realized and unrealized gains and losses of the Fund represent pro rata shares of gains and losses of the Portfolio. 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 are declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for losses deferred due to wash sales and unrealized gains or losses on futures contracts. Permanent book and tax basis differences relating to shareholder distributions result in reclassifications among undistributed net investment income(loss), accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (loss) and accumulated net realized gain (loss) on investments may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. D. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust and/or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. 9 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Value Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates: The Fund does not directly pay any investment advisory fees, but indirectly bears its pro rata share of the compensation paid by the Portfolio to The Boston Company Asset Management, LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, for such services. See Note 2 of the Portfolio's Notes to Financial Statements which are included elsewhere in this report. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $18,109 for the six months ended March 31, 2007. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,121, which 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 Portfolio Trust 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. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $200, which is included in miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. The Fund pays 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, 2007, the Fund was charged $50,143 for fees payable to Mellon Private Wealth Management. 10 Mellon Institutional Funds Investment Trust The Boston Company Small Cap Value Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended March 31, 2007 aggregated $271,003,432 and $99,359,247, respectively. The Fund receives a proportionate share of the Portfolio's income, expense and realized and unrealized gains and losses based on applicable tax allocation rules. Book/tax differences arise when changes in proportionate interest for funds investing in the Portfolio occur. (4) Shares of Beneficial Interest: The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest having a par value of one cent per share. Transactions in Fund shares were as follows: For the For the Six Months Ended Year Ended March 31, 2007 September 30, 2006 -------------- ------------------ Shares sold 10,044,518 16,310,078 Shares issued to shareholders in reinvestment of distributions 806,247 464,397 Shares redeemed (2,908,946) (2,415,192) ---------- ---------- Net increase (decrease) 7,941,819 14,359,283 ========== ========== At March 31, 2007, one shareholder of record held, in the aggregate, approximately 20% of the total outstanding shares of the Fund. Investment activities of this shareholder could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that are acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund received $15,795 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. See the corresponding master portfolio for tax basis unrealized appreciation (depreciation) information. 11 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Value Portfolio Schedule of Investments--March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Value Security Shares (Note 1A) - --------------------------------------------------------------------------- UNAFFILIATED INVESTMENTS--115.7% EQUITIES--95.9% Consumer Discretionary--16.1% Aeropostale, Inc.

The Boston Company Small Cap Value Portfolio (the "Portfolio"), is a separate diversified investment series of the Portfolio Trust. The objective of the Portfolio is to achieve long-term growth of capital. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in equity securities of small cap U.S. companies. At March 31, 2007, there were two funds, The Boston Company Small Cap Value Fund and Dreyfus Premier Small Cap Equity Fund invested in the Portfolio (the "Feeder Funds"). The value of the Feeder Funds' investment in the Portfolio reflects the Feeder Funds' proportionate interests in the net assets of the Portfolio. At March 31, 2007, The Boston Company Small Cap Value Fund (the "Fund") and the Dreyfus Premier Small Cap Equity Fund held 91% and 9% interests in the Portfolio, respectively. The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities 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 market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Portfolio's assets that are invested in one or more open open-ended regulated investment companies ("RICs"), the Portfolio'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. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Portfolio acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity. Dividend income is recorded on ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. C. Income taxes The Portfolio is treated as a partnership for federal tax purposes. No provision is made by the Portfolio for federal or state income taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes. Since the Portfolio's investor is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the source of income and diversification requirements applicable to regulated investment companies (under the Internal Revenue Code) in order for its investors to satisfy them. 21 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Value Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- D. Commitments and contingencies In the normal course of business, the Portfolio may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Portfolio under these arrangements is unknown, as this would involve future claims that may be made against the Portfolio that have not yet occurred. However, based on experience, the Portfolio expects the risks of loss to be remote. E. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. F. Affiliated issuers Affiliated issuers are investment companies advised by The Boston Company Asset Management LLC ("TBCAM"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. G. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory and Other Transactions With Affiliates: The investment advisory fee paid to TBCAM for overall investment advisory, administrative services, and general office facilities, is paid monthly at the annual rate of 0.80% of the Portfolio's average daily net assets. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Portfolio Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide custody, administration and accounting services for the Portfolio. For these services the Portfolio pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Portfolio was charged $92,264 for the six months ended March 31, 2007. The Portfolio Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Portfolio's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $29,891 for the six months ended March 31, 2007. See Note 6 for further details. 22 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Value Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's and Portfolio Trust's Chief Compliance Officer. No other director, officer or employee of TBCAM or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust or Portfolio Trust. The Fund and Portfolio Trust pays each Trustee who is not a director, officer or employee of TBCAM or its affiliates (the "Independent Trustees") an annual fee and the Portfolio Trust pays each Independent Trustee a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Portfolio Trust pays the legal fees for the counsel to the Independent Trustees. (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, 2007 were as follows: Purchases Sales ------------ ------------- Non-U.S. Government Securities $333,503,880 $186,983,348 ============ ============= (4) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $952,235,890 ============ Gross unrealized appreciation 93,631,210 Gross unrealized depreciation (18,432,481) ------------ Net unrealized appreciation (depreciation) $ 75,198,729 ============ (5) Financial Instruments: In general, the following instruments are used for hedging purposes as described below. However, these instruments may also be used to seek to enhance potential gain in circumstances where hedging is not involved. The Portfolio may trade the following financial instruments with off-balance sheet risk: Futures contracts The Portfolio may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments, known as variation margin, are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized appreciation or depreciation by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. At March 31, 2007, the Portfolio held open financial futures contracts. See Schedule of Investments for further details. 23 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Value Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (6) Security Lending: The Portfolio may lend its securities to financial institutions which the Portfolio deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Portfolio on the next business day. For the duration of a loan, the Portfolio receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Portfolio bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Portfolio. In the event of borrower default, the Portfolio generally has the right to use the collateral to offset losses incurred. The Portfolio may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Portfolio also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Fund's obligations due on the loans. The Portfolio loaned securities for the six months ended March 31, 2007 and earned interest on the invested collateral of $3,092,005 of which, $3,020,989 was rebated to borrowers or paid in fees. At March 31, 2007, the Portfolio had securities valued at $162,111,298 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. (7) Line of Credit: The Portfolio, and other subtrusts in the Portfolio Trust and funds in the Trust are parties to a committed line of credit facility, which enables each portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is charged to each participating portfolio/fund based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating portfolios/funds at the end of each quarter. The participating portfolios and funds also pay an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating portfolio/fund. For the six months ended March 31, 2007, the expense allocated to the Portfolio was $1,939. The commitment fee and interest expense is aggregated with miscellaneous expenses on the Statement of Operations. For the six months ended March 31, 2007, the Portfolio did not borrow from the line of credit. 24 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Value Portfolio Factors Considered by Board of Trustees in Approving 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. The Fund is not a party to an investment advisory agreement directly with any investment adviser and does not invest directly in portfolio securities. Instead, the Fund invests all of its investable assets in The Boston Company Small Cap Value Portfolio (the "Portfolio"), which is managed by The Boston Company Asset Management LLC ("TBCAM"). The Fund's Board of Trustees determines annually whether the Fund should continue to invest in the Portfolio. The members of the Fund's Board of Trustees also serve as the Board of Trustees of the Portfolio. In that capacity, they consider annually whether to continue the investment advisory agreement between the Portfolio and TBCAM. 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 Portfolio's investment adviser, TBCAM ("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 28, 2006 to review these materials and to discuss the proposed continuation of the Fund's advisory agreement. Representatives of the Adviser attended a portion of the September meeting to provide an overview of its 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 17, 2006. 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 (rather than the Portfolio alone), 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 and Portfolio, including Portfolio'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 Portfolio and potential economies of scale; and (v) Other Benefits: The benefits flowing to Mellon Financial Corporation ("Mellon") in the form of revenues received by Mellon affiliates in consideration of custodial, administrative, transfer agency and securities lending services provided by such affiliates to the Funds. In considering the continuation of the Portfolio'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 Portfolio 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 Portfolio'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 Portfolio effectively. 25 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Value Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Investment Performance The Board considered the investment performance of the Fund (rather than the Portfolio alone) 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 28, 2006 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, 2006 based on the Lipper materials provided to the Board at the September 28, 2006 meeting. The Board found that the Fund outperformed its peer group average return for the one-year period (6.83% vs. 5.00%), three-year period (20.23% vs. 18.01%) and five-year period (15.10% vs. 12.98%). Advisory Fee and Other Expenses The Board considered the advisory fee rate paid by the Portfolio to the Adviser. The Lipper data presenting the Portfolio's "net management fees" included fees paid by the Portfolio, as calculated by Lipper, for administrative services provided by Mellon Bank, N.A., the Portfolio's custodian. Such reporting was necessary, according to Lipper, to allow the Board to compare the Portfolio's advisory fees to those peers that include administrative fees within a blended advisory fee. The Portfolio's contractual advisory fee was 0.800%, in the 4th quintile (1st being the best) of its peer group of funds, the median fee of which was 0.779%. The Portfolio's net management fee was 0.897% (which included 0.102% in administrative services fees under Lipper's calculation methodology), higher than the peer group median net management fee of 0.773%. Based on the Lipper data, as well as other factors discussed at the September 28, 2006 meeting, the Board determined that the Portfolio's advisory fee is reasonable relative to its peer group averages. The Board also compared the fees payable by the Portfolio 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 Portfolio 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 (rather than solely the Portfolio'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 1.045% was slightly higher than the median net expense ratio of the peer group of 1.028%. However, 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 Portfolio and 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 adviser, Standish Mellon Asset Management Company LLC ("Standish Mellon") in managing the Portfolio and other funds in the Mellon Institutional Funds family of funds. The Independent Trustees had observed that the Adviser, based on profitability information submitted to them by the Adviser, incurred marginal profitability in managing most of the investment companies in the Mellon Institutional Funds family of funds. The Trustees observed that the Adviser had experienced profits in operating the Portfolio in both 2004 and 2005 and concluded these were not excessive. 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 Boston Company International Core Equity Portfolio and the Standish Mellon Fixed Income Portfolio, 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. 26 Mellon Institutional Funds Master Portfolio The Boston Company Small Cap Value Portfolio Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Other Benefits The Board also considered the additional benefits flowing to Mellon as a result of its relationship with the Mellon Institutional Funds as a group, including revenues received by 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 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 Portfolio'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. 27 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

Mellon Institutional Funds Investment Trust The Boston Company World ex-U.S. 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, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ---------------------------------------------------------------------------------------------------------------------------- Actual $1,000.00 $1,105.90 $4.73 Hypothetical (5% return per year before expenses) $1,000.00 $1,020.44 $4.53 - ---------- + Expenses are equal to the Fund's annualized expense ratio of 0.90%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). 3 Mellon Institutional Funds Investment Trust The Boston Company World ex-U.S. Value Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Holdings* Country Sector Investments - -------------------------------------------------------------------------------------------------------- Sanofi-Synthelabo SA France Health Care 2.0% Novartis AG Switzerland Health Care 1.9 BP PLC United Kingdom Energy 1.9 Unilever PLC United Kingdom Consumer Staples 1.9 HSBC Holdings PLC United Kingdom Financials 1.9 GlaxoSmithKline PLC United Kingdom Health Care 1.9 Total SA France Energy 1.8 Sumitomo Mitsui Financial Japan Financials 1.6 Royal Bank of Scotland Group PLC United Kingdom Financials 1.5 Siemens AG Germany Industrials 1.3 ---- 17.7% * Excludes short-term securities.

The Boston Company World ex-U.S. 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 located in foreign countries represented in the Morgan Stanley Capital International All Country World Index ex-United States Free Index. The Fund may invest up to 35% 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 market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Fund's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. 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 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. 15 Mellon Institutional Funds Investment Trust The Boston Company World ex-U.S. Value Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. The Fund's distributions from capital gains, if any, after reduction of capital losses will be declared and distributed at least annually. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless the shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for foreign currency transactions and losses deferred due to wash sales. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income (loss), accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (loss) and accumulated net realized gain (loss) on investments may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. Section 988 of the Internal Revenue Code provides that gains or losses on certain transactions attributable to fluctuations in foreign currency exchange rates must be treated as ordinary income or loss. For financial statement purposes, such amounts are included in net realized gains or losses. D. Expenses The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated among 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 Mellon Financial Corporation, or its affiliates. 16 Mellon Institutional Funds Investment Trust The Boston Company World ex-U.S. Value Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- I. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact, if any, in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions With Affiliates The investment advisory fee paid to TBCAM for overall investment advisory and administrative services, and general office facilities, is paid monthly at the annual rate of 0.75% of the Fund's average daily net assets. TBCAM voluntarily agreed to limit the Fund's total annual operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.90% of the Fund's average daily net assets for the six months ended March 31, 2007. Pursuant to this arrangement, for the six months ended March 31, 2007, waived $100,477 of its investment advisory fee. This arrangement is voluntary and temporary and may be discontinued or revised by TBCAM at any time. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, TBCAM would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of TBCAM, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as, out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $4,263, for the six months ended March 31, 2007. The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation 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 $83,627 for the six months ended March 31, 2007. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,105, which 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 Mellon Financial Corporation and an affiliate of TBCAM, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $1,075, which is included in miscellaneous expenses in the statement of operations, for the six months ended March 31, 2007. 17 Mellon Institutional Funds Investment Trust The Boston Company World ex-U.S. Value Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Fund pays 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, 2007, the Fund was not charged an administrative service fee. (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, 2007 were as follows: Purchases Sales ------------ ------------ Non-U.S. Government Securities $ 17,581,067 $ 20,467,497 ============ ============ (4) Shares of Beneficial Interest: The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest having a par value of one cent per share. Transactions in Fund shares were as follows: For the For the Six Months Ended Year Ended March 31, 2007 September 30, 2006 ---------------- ------------------ Shares sold 39,855 909,550 Shares issued to shareholders in reinvestment of distributions 256,406 74,197 Shares redeemed (171,224) (191,000) --------- --------- Net increase (decrease) 125,037 792,747 ========= ========= At March 31, 2007, four shareholders of record, in the aggregate, held approximately 87% of the total outstanding shares of the Fund. Investment activities of these shareholders could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended March 31, 2007, the Fund did not assess any redemption fees. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $50,628,721 ----------- Gross unrealized appreciation 6,398,808 Gross unrealized depreciation ( 1,051,039) ----------- Net unrealized appreciation (depreciation) $ 5,347,769 =========== 18 Mellon Institutional Funds Investment Trust The Boston Company World ex-U.S. Value Fund 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 Currency Exchange Contracts The Fund may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Fund primarily to protect the value of the Fund's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At March 31, 2007, the Fund held foreign currency exchange contracts. See Schedule of Investments for further details. (7) Line of Credit The Fund, and other funds in the Trust and subtrusts in Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") are parties to a committed line of credit facility, which enables each fund/portfolio to borrow, in the aggregate, up to $35 million. Interest is charged to each participating fund/portfolio based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating funds/portfolios at the end of each quarter. Each fund/portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating funds/portfolios. For the six months ended March 31, 2007, the expense allocated to the Fund was $1,394. The facility fee and interest expense are included in miscellaneous expenses on the statement of operations. For the six months ended March 31, 2007, the Fund had average borrowings outstanding of $1,153,800 for a total of five days and incurred $926 of interest expense. At March 31, 2007 the Fund had no borrowings outstanding 19 Mellon Institutional Funds Investment Trust The Boston Company World ex-U.S. Value Fund Factors Considered by Board of Trustees in Approving 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 28, 2006 to review these materials and to discuss the proposed continuation of the Fund's advisory agreement. Representatives of the Adviser attended a portion of the September meeting to provide an overview of its 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 17, 2006. 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 Mellon Financial Corporation ("Mellon") in the form of revenues received by Mellon affiliates in consideration of custodial, administrative, transfer agency and securities lending services provided by such affiliates to the Funds. 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 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 for at the September 28, 2006 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, 2006 based on the Lipper materials provided to the Board at the September 28, 2006 meeting. The Board found that the Fund underperformed its peer group average returns for the one-year period (20.04% vs. 23.52%). 20 Mellon Institutional Funds Investment Trust The Boston Company World ex-U.S. Value Fund Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- Advisory Fee and Other Expenses The Board considered the advisory fee rate paid by the Fund to the Adviser. The Fund's contractual advisory fee was 0.750%, in the 2nd quintile (1st being the best) of its peer group of funds, the median fee of which was 0.750%. The Fund's net management fee, after giving effect to expense limitations, was 0.00%, while the peer group median net management fee was 0.786%. Based on the Lipper data, as well as other factors discussed at the September 28, 2006 meeting, the Board determined that the Fund's advisory fee is reasonable relative to its peer group averages, both with and without giving effect to expense limitations. 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 0.904% (after giving effect to expense limitations) was lower than the median net expense ratio of the peer group of 0.978%, 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 adviser, Standish Mellon Asset Management Company LLC ("Standish Mellon") 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 profitability information submitted to them by the Adviser, incurred marginal profitability in managing most 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 both 2004 and 2005. 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 Boston Company International Core Equity Portfolio and the Standish Mellon Fixed Income Portfolio and, 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 assets 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 Mellon as a result of its relationship with the Mellon Institutional Funds as a group, including revenues received by 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 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 the Adviser provided therein are fair and reasonable and, thus, in approving the continuation of the agreement for a one-year period. 21 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.

Mellon Institutional Funds Investment Trust Standish Mellon Intermediate Tax Exempt Bond Fund Shareholder Expense Example (Unaudited) - -------------------------------------------------------------------------------- As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (October 1, 2006 to March 31, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value October 1, 2006 October 1, 2006 March 31, 2007 to March 31, 2007 - ------------------------------------------------------------------------------------------------------------------ Actual $1,000.00 $1,016.60 $2.26 Hypothetical (5% return per year before expenses) $1,000.00 $1,022.69 $2.27 - -------------- + Expenses are equal to the Fund's annualized expense ratio of 0.45%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). 3 Mellon Institutional Funds Investment Trust Standish Mellon Intermediate Tax Exempt Bond Fund Portfolio Information as of March 31, 2007 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Holdings* Rate Maturity Investments - --------------------------------------------------------------------------------------------------------- Tennessee Energy Acquisition Corp. 5.250% 9/1/2017 2.1% New York Dormitory Authority Revenue 5.250 11/15/2023 1.7 Golden State Tobacco Securitization Corp. 4.500 6/1/2027 1.5 Puerto Rico Public Financial Corp.

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. With respect to any portion of the Fund's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. Exchange traded options and futures are valued at the settlement price determined by the relevant exchange. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers, including counterparties, or pricing services. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Fund acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity. Dividend income is recorded on ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. C. Distributions to shareholders Distributions on shares of the Fund are declared daily from net investment income and distributed monthly. Distributions from capital gains, if any, are distributed annually by the Fund. Distributions from net investment income and capital gains, if any, are automatically reinvested in additional shares of the applicable Fund unless the shareholder elects to receive them in cash. Distributions are recorded on the ex-dividend date. Income and capital gains distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for losses deferred due to wash sales, post-October losses, capital loss carryovers and amortization and/or accretion of premiums and discounts on certain securities. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income (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 reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. D. Expenses The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated 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. 13 Mellon Institutional Funds Investment Trust Standish Mellon Intermediate Tax Exempt Bond Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- E. Commitments and contingencies In the normal course of business, the Fund may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Fund under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risks of loss to be remote. F. Affiliated issuer Affiliated issuers are investment companies advised by Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. G. New Accounting Requirements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined. In addition, on September 20, 2006, FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory and administrative services, and general office facilities, is paid monthly at the annual rate of 0.40% of the Fund's average daily net assets. Standish Mellon voluntarily agreed to limit the Fund's total annual operating expenses (excluding brokerage commissions, taxes and other extraordinary expenses) to 0.45% of the Fund's average daily net assets for the six months ended March 31, 2007. Pursuant to this arrangement, for the six months ended March 31, 2007, Standish Mellon voluntarily waived $98,905 of its advisory fee. This arrangement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of New York Company, Inc. ("BNY") announced that they had entered into a definitive agreement to merge. The new company will be called The Bank of New York Mellon Corporation. As part of this transaction, Standish Mellon would become an indirect wholly-owned subsidiary of The Bank of New York Mellon Corporation. The transaction is subject to certain regulatory approvals and the approval of BNY's and MFC's shareholders, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, MFC and BNY expect the transaction to be completed in the third quarter of 2007. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of 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 $5,619 for the six months ended March 31, 2007. The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly-owned subsidiary of Mellon Financial Corporation and an affiliate of Standish Mellon, to provide custody, administration and accounting services for the Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $54,886 for the six months ended March 31, 2007. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended March 31, 2007, the Fund was charged $2,101. 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. 14 Mellon Institutional Funds Investment Trust Standish Mellon Intermediate Tax Exempt Bond Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of Mellon Financial Corporation and an affiliate of Standish Mellon, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $1,144, which is included as miscellaneous expenses in the statement of operations for the six months ended March 31, 2007. The Fund pays 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 (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, 2007 were as follows: Purchases Sales ----------- ---------- Investments (non-U.S. Government Securities) $36,780,540 $8,620,629 =========== ========== (4) Shares of Beneficial Interest: The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest having a par value of one cent per share. Transactions in Fund shares were as follows: For the For the Six Months Ended Year Ended March 31, 2007 September 30, 2006 ---------------- ------------------ Shares sold 2,102,257 2,339,293 Shares issued to shareholders in reinvestment of distributions 96,602 161,970 Shares redeemed (693,712) (1,638,284) --------- ---------- Net increase (decrease) 1,505,147 862,979 ========= ========== At March 31, 2007, two shareholders of record held, in the aggregate, approximately 82% of the total outstanding shares of the Fund. Investment activities of these shareholders could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 7 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, 2007, the Fund received $56 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. 15 Mellon Institutional Funds Investment Trust Standish Mellon Intermediate Tax Exempt Bond Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The cost and unrealized appreciation (depreciation) in value of the investment securities owned at March 31, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $157,678,611 ------------ Gross unrealized appreciation 1,696,431 Gross unrealized depreciation (517,946) ------------ Net unrealized appreciation (depreciation) $1,178,485 ============ (6) Line of Credit The Fund, and other funds in the Trust and subtrusts in Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") are parties to a committed line of credit facility, which enables each fund/portfolio to borrow, in the aggregate, up to $35 million. Interest is charged to each participating fund/portfolio based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating funds/portfolios at the end of each quarter. Each fund/portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating funds/portfolios. For the six months ended March 31, 2007, the expense allocated to the Fund was $541. The facility fee and interest expense are included in miscellaneous expenses on the statement of operations. For the six months ended March 31, 2007, the Fund had average borrowings outstanding of $533,000 for a total of twelve days and incurred $1,038 of interest expense. At March 31, 2007 the Fund had no borrowings outstanding. 16 Mellon Institutional Funds Investment Trust Standish Mellon Intermediate Tax Exempt Bond Fund Factors Considered by Board of Trustees in Approving 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 28, 2006 to review these materials and to discuss the proposed continuation of the Fund's advisory agreement. Representatives of the Adviser attended a portion of the September meeting to provide an overview of its 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 17, 2006. 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 Mellon Financial Corporation ("Mellon") in the form of revenues received by Mellon affiliates in consideration of custodial, administrative, transfer agency and securities lending services provided by such affiliates to the Funds. 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 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 for at the September 28, 2006 Board meeting, the Trustees received similar detailed comparative performance information for the Fund at each regular Board meeting during the year. 17 Mellon Institutional Funds Investment Trust Standish Mellon Intermediate Tax Exempt Bond Fund Factors Considered by Board of Trustees in Approving Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- The Board considered the Fund's performance for the one-, three- and five-year periods ended July 31, 2006 based on the Lipper materials provided to the Board at the September 28, 2006 meeting. The Board found that the Fund slightly underperformed its peer group average returns for the one-year period (2.09% vs. 2.12%), three-year period (3.31% vs. 3.49%) and five-year period (3.90% vs. 3.95%). The Board noted the Fund's improved recent performance, which was reported in the September 28, 2006 Board meeting Fund Reports. Advisory Fee and Other Expenses The Board considered the advisory fee rate paid by the Fund to the Adviser. The Fund's contractual advisory fee was 0.400%, in 2nd quintile (1st being the best) of its peer group of funds, the median fee of which was 0.453%. The Fund's net management fee, after giving effect to expense limitations, was 0.231%, well below the peer group median net management fee of 0.394%. Based on the Lipper data, as well as other factors discussed at the September 28, 2006 meeting, the Board determined that the Fund's advisory fee is reasonable relative to its peer group averages, both with and without giving effect to expense limitations. 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 0.450% (after giving effect to expense limitations) was lower than the median net expense ratio of the peer group of 0.565%, 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 adviser, The Boston Company Asset Management, LLC ("TBCAM") 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 all but one 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 both 2004 and 2005. 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 Portfolio and The Boston Company International Core Equity Portfolio, 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 assets 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 Mellon as a result of its relationship with the Mellon Institutional Funds as a group, including revenues received by 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 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 the Adviser provided therein are fair and reasonable and, thus, in approving the continuation of the agreement for a one-year period. 18 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their address and date of birth; their position with the Trust; the length of time holding that position with the Trust; their principal occupation(s) during the past five years; the number of portfolios in the fund complex they oversee; other directorships they hold in companies subject to registration or reporting requirements of the Securities Exchange Act of 1934 (generally called "public companies") or in registered investment companies; and total remuneration paid as of the period ended March 31, 2007.
