Mellon Institutional Funds Investment Trust Standish Mellon Enhanced Yield 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 (January 1, 2006 to June 30, 2006). 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 expenses 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 January 1, 2006 January 1, 2006 June 30, 2006 to June 30, 2006 - ------------------------------------------------------------------------------------------------------------------------------------ Actual $1,000.00 $1,023.40 $1.25 Hypothetical (5% return per year before expenses) $1,000.00 $1,023.55 $1.25 - ------------------------- (+) Expenses are equal to the Fund's annualized expense ratio of 0.25%, multiplied by the average account value over the period, multiplied by 181/365 (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. 1 Mellon Institutional Funds Investment Trust Standish Mellon Enhanced Yield Fund - -------------------------------------------------------------------------------- Portfolio Information as of June 30, 2006 (Unaudited) Percentage of Economic Sector Allocation Investments - -------------------------------------------------------------------------------- Treasury/Agency 5.0% Credit 5.5 Floating rate credit 27.1 Asset-Backed 20.0 Floating rate asset-backed 33.5 CMBS 1.4 Cash & equivalents 7.5 ----- 100.0% Percentage of Top Ten Holdings* Rate Maturity Investments - ------------------------------------------------------------------------------------------------------ Citibank Credit Card Issuance Trust 2004-A1 A1 2.550 1/20/2009 3.9% Wachovia Corp. 5.384 7/20/2007 3.2 Residential Asset Securities Corp. 2005-EMX2 A2 5.483 7/25/2035 3.2 Wells Fargo & Co. 5.220 3/10/2008 3.2 Fremont Home Loan Trust 2006-1 M1 5.643 4/25/2036 3.2 Countrywide Alternative Loan Trust 2006-6CB 1A2 5.500 5/25/2036 3.1 Countrywide Alternative Loan Trust 2005-65CB 1A5 5.500 1/25/2036 3.1 Morgan Stanley 5.800 4/1/2007 3.0 HBOS Treasury Services PLC 144A 5.125 1/12/2007 2.8 CIT Group, Inc. 5.837 9/22/2006 2.8 ----- 31.5% * Excluding short-term investments and investment of cash collateral.

Standish Mellon Enhanced Yield 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 Standish Mellon Enhanced Yield Portfolio (the "Portfolio"), a subtrust of the 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 dollar-denominated money market instruments, short-term fixed income securities and asset-backed securities of U.S. and foreign governments, banks and companies. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio (100% at June 30, 2006). 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 The Fund records its investment 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 Securities transactions in the Portfolio are recorded as of the trade date. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all 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 will be declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless 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, amortization and/or accretion of premiums and discounts on certain securities and the timing of recognition of gains and losses on futures contracts. Permanent book and tax basis differences 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 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. 7 Mellon Institutional Funds Investment Trust Standish Mellon Enhanced Yield 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. (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 Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary Mellon Financial Corporation, for such services. See Note 2 of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. Standish Mellon voluntarily agreed to limit the total operating expenses of the Fund and its pro rata share of the Portfolio expenses (excluding brokerage commissions, taxes and extraordinary expenses) 0.25%. Pursuant to these agreements, for the six months ended June 30, 2006, Standish Mellon voluntarily reimbursed the Fund for $35,210 of its operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Fund 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 $4,476 during the six months ended June 30, 2006. The Fund 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 $1,436 during the six months ended June 30, 2006. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2006, the Fund was charged $1,905. No other director, officer or employee of Standish Mellon or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust or the Portfolio Trust. The Fund pays each Trustee who is not a director, officer or employee of Standish Mellon 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 June 30, 2006, the Fund was charged $1,585 for fees payable to Mellon Private Wealth Management. (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended June 30, 2006, aggregated $1,141,016 and $9,350,132, respectively. The Fund receives a proportionate share of the Portfolio's income, expenses, 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 June 30, 2006 December 31, 2005 ---------------- ----------------- Shares sold 74,000 786,928 Shares issued to shareholders for reinvestment of distributions 33,139 77,632 Shares redeemed (446,533) (2,327,112) ---------- ----------- Net increase (decrease) (339,394) (1,462,552) ========== =========== 8 Mellon Institutional Funds Investment Trust Standish Mellon Enhanced Yield Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- At June 30, 2006, one shareholder of record held approximately 16% of the total outstanding shares of the Fund. Investment activity 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 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 their 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 June 30, 2006, the Fund did not receive any redemption fees.

Standish Mellon Enhanced Yield Portfolio (the "Portfolio") is a separate diversified investment series of the Portfolio Trust. The objective of the Portfolio is to achieve a high level of current income consistent with preserving principal and liquidity. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in dollar-denominated money market instruments, short-term fixed income securities and asset-backed securities of U.S. and foreign governments, banks and companies. At June 30, 2006 there was one fund, Standish Mellon Enhanced Yield 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 June 30, 2006 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 quoted bid price. 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. 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. 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 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 disregarded entity 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. 17 Mellon Institutional Funds Master Portfolio Standish Mellon Enhanced Yield 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 Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory, administrative services, and general office facilities is paid monthly at the annual rate of 0.20% of the Portfolio's average daily net assets. Standish Mellon voluntarily agreed to limit the total operating expenses of the Fund and its pro rata share of the Portfolio expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.25% for the six month period ending June 30, 2006. Pursuant to these agreements, for the six months ended June 30, 2006, Standish Mellon voluntarily waived a portion of its investment advisory fee in the amount of $35,315 and reimbursed the Portfolio $10,326 of other operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Portfolio 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 fund 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 $35,063 for the six months ended June 30, 2006. The Portfolio 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 received $90 for the six months ended June 30, 2006. See Note 6 for further details. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. No other director, officer or employee of Standish Mellon or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust or the Portfolio Trust. The Fund and Portfolio Trust pays each Trustee who is not a director, officer or employee of Standish Mellon 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 June 30, 2006 were as follows: Purchases Sales ------------ ----------- U.S. Government Securities $ 0 $ 2,556,114 ============ =========== Investments (non-U.S. Government Securities) $ 6,106,338 $ 7,916,039 ============ =========== 18 Mellon Institutional Funds Master Portfolio Standish Mellon Enhanced Yield Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (4) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2006, as computed on a federal income tax basis, were as follows: Aggregate cost $31,863,192 =========== Gross unrealized appreciation 35,677 Gross unrealized depreciation (190,077) ----------- Net unrealized appreciation (depreciation) $(154,400) =========== (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 are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized gains or losses by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. At June 30, 2006, the Portfolio held open financial futures contracts. See the Schedule of Investments for further details. (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 are not sufficient to meet the Portfolio's obligations due on the loans.

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. For the six months ended June 30, 2006, the facility fee was $176 for the Portfolio. For the six months ended June 30, 2006, the Portfolio did not borrow from the credit facility. 20 Trustees and Officers 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 June 30, 2006.

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.

Mellon Institutional Funds Investment Trust Standish Mellon Emerging Markets Debt 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 (January 1, 2006 to June 30, 2006). 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 expenses 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 January 1, 2006 January 1, 2006 June 30, 2006 to June 30, 2006 Actual $1,000.00 $ 990.80 $3.21 Hypothetical (5% return per year before expenses) $1,000.00 $1,021.57 $3.26 - ------- + Expenses are equal to the Fund's annualized expense ratio of 0.65%, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 1 Mellon Institutional Funds Investment Trust Standish Mellon Emerging Markets Debt Fund Portfolio Information as of June 30, 2006 (Unaudited) -

Standish Mellon Emerging Markets Debt Fund (the "Fund") is a separate non-diversified investment series of the Trust. The Fund's Board of Trustees approved, effective November 1, 2005, the change in the Fund's name from "Standish Mellon Opportunistic Emerging Markets Debt Fund" to "Standish Mellon Emerging Markets Debt Fund". The objective of the Fund is to generate a high total return through a combination of capital appreciation and income. The fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in fixed income securities issued by governments, companies and banks of emerging markets, as well as preferred stocks, warrants and tax-exempt bonds. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities 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 quoted bid price. 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. 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. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. The Fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. Net realized gains and losses on foreign currency transactions represent gains and losses on disposition of foreign currencies and forward foreign currency exchange contracts, currency gains and losses realized between the trade and settlement dates on securities transactions, and the difference between the amount of investment income and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent amounts actually received or paid. C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. 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, amortization and/or accretion of premiums and discounts on certain securities, capital loss carryforwards and the timing of recognition of gains and losses on futures contracts. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income(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. 10 Mellon Institutional Funds Investment Trust Standish Mellon Emerging Markets Debt Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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 Fund maintains its 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. 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. 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. 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 Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. (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, payable monthly at the annual rate of 0.50% of the Fund's average daily net assets. Standish Mellon voluntarily agreed to limit total Fund operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.65%. Pursuant to this agreement, for the six months ended June 30, 2006, Standish Mellon voluntarily waived its investment advisory fee in the amount of $14,269 and reimbursed the Fund for $51,810 of other operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Fund 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 $3,039 during the six months ended June 30, 2006. The Fund 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 fund accounting services for the Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement the Fund was charged $24,332 during the six months ended June 30, 2006. The Fund 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 was charged $850 for the six months ended June 30, 2006. See Note 7 for further details. 11 Mellon Institutional Funds Investment Trust Standish Mellon Emerging Markets Debt Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Fund 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. The Fund was not charged for printing and fulfillment services during the six months ended June 30, 2006. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2006, the Fund was charged $1,962. 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 Trust pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee and a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Trust pays the legal fees for the independent counsel of the Trustees. 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 June 30, 2006, the Fund was charged $0 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 June 30, 2006 were as follows: Purchases Sales --------- ----- U.S. Government Securities $ 61,000 $ 60,830 Investments (non-U.S. Government Securities) $ 4,365,358 $ 9,946,083 (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 June 30, 2006 December 31, 2005 ---------------- ----------------- Shares sold -- 170,232 Shares issued to shareholders reinvestment of distributions declared 10,017 59,293 Shares redeemed (299,176) (343,898) -------- -------- Net increase (decrease) (289,159) (114,373) ======== ======== At June 30, 2006, one shareholder of record held 100% of the total outstanding shares of the Fund. Investment activity 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 June 30, 2006, the Fund did not collect any redemption fees (5) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2006, as computed on a federal income tax basis, were as follows: Aggregate cost $ 2,636,049 Gross unrealized appreciation 41,177 Gross unrealized depreciation (119,337) Net unrealized appreciation (depreciation) $ (78,160) 12 Mellon Institutional Funds Investment Trust Standish Mellon Emerging Markets Debt 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 instruments with off-balance sheet risk: Options Call and put options give the holder the right to purchase or sell a security or currency or enter into a swap arrangement on a future date at a specified price. The Fund may use options to seek to hedge against risks of market exposure and changes in security prices and foreign currencies, as well as to seek to enhance returns. Writing puts and buying calls tend to increase the Fund's exposure to the underlying instrument. Buying puts and writing calls tend to decrease the Fund's exposure to the underlying instrument, or hedge other Fund investments. Options, both held and written by the Fund, are reflected in the accompanying Statement of Assets and Liabilities at market value. The underlying face amount at value of any open purchased option is shown in the Schedule of Investments. This amount reflects each contract's exposure to the underlying instrument at year end. Losses may arise from changes in the value of the underlying instruments if there is an illiquid secondary market for the contract or if the counterparty does not perform under the contract's terms. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. Realized gains and losses on purchased options are included in realized gains and losses on investment securities, except purchased options on foreign currency which are included in realized gains and losses on foreign currency transactions. If a put option written by the Fund is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund, as a writer of an option, has no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by the dealers. During the six months ended June 30, 2006, the Fund entered into the following transactions: Number of Written Put Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period 0 $ -- Options written 5 420 Options expired (5) (420) Options closed 0 -- --------- -------- Outstanding, end of period 0 $ -- ========= ======== Number of Written Call Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period 1 $ 960 Options written 1 51 Options expired (1) (51) Options closed (1) (960) --------- -------- Outstanding, end of period 0 $ -- ========= ======== At June 30, 2006, the Fund did not hold options. See the Schedule of Investments for further details. 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 13 Mellon Institutional Funds Investment Trust Standish Mellon Emerging Markets Debt Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any gains or losses are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Fund primarily to protect the value of the Fund's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2006, the Fund held currency exchange contracts. See the Schedule of Investments for further details. Swap agreements The Fund may enter into swap agreements. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The Fund may enter into interest rate, credit default and total return swap agreements to manage its exposure to interest rates and credit risk. Interest rate swap agreements involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. In a credit default swap, one party makes a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party on its obligation. The Fund may use credit default swaps to provide a measure of protection against defaults of issuers (i.e., to reduce risk where the Fund owns or has exposure to the corporate or sovereign issuer) or to take an active long or short position with respect to the likelihood of a particular corporate or sovereign issuer's default. Total return swap agreements involve commitments to pay interest in exchange for a market-linked return, both based on notional amounts. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, a fund will receive a payment from or make a payment to the counterparty. In connection with these agreements, cash or securities may be set aside as collateral in accordance with the terms of the swap agreement. Swaps are marked to market daily based upon quotations, which may be furnished by a pricing service or dealers in such securities and the change in value, if any, is recorded as unrealized gain or loss in the Statement of Operations. These financial instruments are not actively traded on financial markets. The values assigned to these instruments are based upon the best available information and because of the uncertainty of the valuation, these values may differ significantly from the values that would have been realized had a ready market for these instruments existed, and differences could be material. Payments received or made at the beginning of the measurement period are reflected as such on the Statement of Assets and Liabilities. Payments received or made from credit default swaps at the end of the measurement period are recorded as realized gain or loss in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gain and loss. Entering into these agreements involves, to varying degrees, elements of credit, market, and documentation risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates. At June 30, 2006, the Fund held open swap agreements. 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 loaned securities during the six months ended June 30, 2006 and earned interest on the invested collateral of $12,339 of which, $10,332 was rebated to borrowers or paid in fees. At June 30, 2006, the Fund had securities valued at $7,105 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. 14 Mellon Institutional Funds Investment Trust Standish Mellon Emerging Markets Debt Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (8) Delayed Delivery Transactions: The Fund may purchase securities on a when-issued, delayed delivery or forward commitment basis. Payment and delivery may take place a month or more after the date of the transactions. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Income on the securities will not be earned until settlement date. The Fund instructs its custodian to segregate securities having value at least equal to the amount of the purchase commitment. The Fund may enter into to be announced (TBA) purchase commitments to purchase securities for a fixed unit price at a future date beyond customary settlement time. Although the unit price has been established, the principal value has not been finalized. However, the amount of the commitments will not fluctuate more than 0.01% from the principal amount. The Fund holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the Fund may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities, according to the procedures described under "Investment security valuations" above. The Portfolio may enter into TBA sale commitments to hedge its portfolio positions. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, an offsetting TBA purchase commitment deliverable is held as "cover" for the transaction. For six months ended June 30, 2006, the Fund did not enter into any delayed delivery transactions. (9) 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 six months ended June 30, 2006, the facility fee was $30 for the Fund. For the six months ended June 30, 2006, the Fund had average borrowings outstanding of $51,714 on a total of seven days and incurred $54 of interest expense. (10) Subsequent Event: In response to total redemption requests submitted by the Fund's remaining shareholders, the Fund began the process of dissolving and winding up its business. On July 31, 2006 the Fund sent a liquidating distribution to its remaining shareholders in cash equal to the shareholders' proportionate interest in the net assets of the Fund. As of such date, the Fund was dissolved in accordance with the Fund's Declaration of Trust. 15 Trustees and Officers 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 June 30, 2006.

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.

Mellon Institutional Funds Investment Trust Standish Mellon Fixed Income 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 (January 1, 2006 to June 30, 2006). 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 expenses 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 January 1, 2006 January 1, 2006 June 30, 2006 to June 30, 2006 Actual $1,000.00 $ 991.90 $2.47 Hypothetical (5% return per year before expenses) $1,000.00 $1,022.32 $2.51 - --------- + Expenses are equal to the Fund's annualized expense ratio of 0.50%, multiplied by the average account value over the period, multiplied by 181/365 (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. 1 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio Portfolio Information as of June 30, 2006 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Summary of Combined Ratings Investments - ----------------------------------------------------------------------- Quality Breakdown - ----------------------------------------------------------------------- AAA and higher 54.8% AA 6.7 A 12.2 BBB 20.7 BB 4.5 B 1.1 ----- 100.0% Based on ratings from Standard & Poor's and/or Moody's Investors Services.

Standish Mellon Fixed Income 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 Standish Mellon Fixed Income Portfolio (the "Portfolio"), a subtrust of the Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust and has the same investment objective as the Fund. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in fixed income securities issued by U.S. and foreign governments and companies. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio (100% at June 30, 2006). 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 The Fund records its investment 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 Securities transactions in the Portfolio are recorded as of the trade date. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all 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 will be declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences which may result in reclassifications, are primarily due to differing treatments for losses deferred due to wash sales, foreign currency gains and losses, post-October losses, amortization and/or accretion of premiums and discounts on certain securities and the timing of recognition of gains and losses on futures contracts. Permanent book and tax basis differences 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. 7 Mellon Institutional Funds Investment Trust Standish Mellon Fixed Income 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. (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 Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, for such services. See Note 2 of the Portfolio's Notes to Financial Statements which are included elsewhere in this report. Standish Mellon voluntarily agreed to limit the total operating expenses of the Fund and its pro rata share of the Portfolio expenses (excluding brokerage commissions, taxes and extraordinary expenses) 0.50%. Pursuant to these agreements, for the six months ended June 30, 2006, Standish Mellon voluntarily reimbursed the Fund for $20,458 of its operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Fund 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 $6,591 during the six months ended June 30, 2006. The Fund 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 $3,160 during the six months ended June 30, 2006. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2006, the Fund was charged $1,933. 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 Trust pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee and a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Trust pays the legal fees for the independent counsel of the Trustees. 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 June 30, 2006, the Fund was charged $81,078 for fees payable to Mellon Private Wealth Management. (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended June 30, 2006, aggregated $45,461,631 and $69,510,754, respectively. The Fund receives a proportionate share of the Portfolio's income, expenses, 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. 8 Mellon Institutional Funds Investment Trust Standish Mellon Fixed Income 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 For the Six Months Ended Year Ended June 30, 2006 December 31, 2005 ------------------ ------------------- Shares sold 2,098,593 2,590,559 Shares issued to shareholders for reinvestment of distributions 359,081 777,096 Shares redeemed (2,939,461) (3,260,750) ----------- ----------- Net increase (decrease) (481,787) (106,905) =========== =========== 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 June 30, 2006, the Fund received $3,571 in redemption fees.

Standish Mellon Fixed Income Portfolio (the "Portfolio") is a separate diversified investment series of the Portfolio Trust. The objective of the Portfolio is to achieve a high level of current income, consistent with conserving principal and liquidity, and secondarily to seek capital appreciation when changes in interest rates and economic conditions indicate that capital appreciation may be available without significant risk to principal by investing, under normal circumstances, at least 80% of net assets in fixed income securities issued by U.S. and foreign governments and companies. At June 30, 2006 there was one fund, Standish Mellon Fixed Income Fund (the "Fund"), invested in the Portfolio. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. The Fund's proportionate interest at June 30, 2006 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 quoted bid price. 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. 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. 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 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 disregarded entity 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. 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. 26 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- D. Foreign currency transactions The Portfolio maintains its 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. 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 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. H. Affiliated issuers 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. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory administrative services, and general office facilities is paid monthly at the annual rate of 0.40% of the Portfolio's first $250,000,000 of average daily net assets, 0.35% of the next $250,000,000 of average daily net assets, and 0.30% of the average daily net assets in excess of $500,000,000. The Portfolio has 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 fund 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 $83,255 during the six months ended June 30, 2006. The Portfolio 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 collected $14,950 for the six months ended June 30, 2006. See Note 6 for further details. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. No other director, officer or employee of Standish Mellon or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust or the Portfolio Trust. The Fund and Portfolio Trust pays each Trustee who is not a director, officer or employee of Standish Mellon 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. 27 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio 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 June 30, 2006 were as follows: Purchases Sales ------------ ------------ U.S. Government Securities $379,346,889 $383,685,576 ============ ============ Investments (non-U.S. Government Securities) $136,256,949 $ 40,837,475 ============ ============ (4) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2006, as computed on a federal income tax basis, were as follows: Aggregate cost $620,567,615 ------------ Gross unrealized appreciation 867,158 Gross unrealized depreciation (10,912,705) ------------ Net unrealized appreciation (depreciation) ($10,045,547) ============ (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: Options Call and put options give the holder the right to purchase or sell a security or currency or enter into a swap arrangement on a future date at a specified price. The Portfolio may use options to seek to hedge against risks of market exposure and changes in security prices and foreign currencies, as well as to seek to enhance returns. Writing puts and buying calls tend to increase the Portfolio's exposure to the underlying instrument. Buying puts and writing calls tend to decrease the Portfolio's exposure to the underlying instrument, or hedge other Portfolio investments. Options, both held and written by the Portfolio, are reflected in the accompanying Statement of Assets and Liabilities at market value. The underlying face amount at value of any open purchased option is shown in the Schedule of Investments. This amount reflects each contract's exposure to the underlying instrument at year end. Losses may arise from changes in the value of the underlying instruments if there is an illiquid secondary market for the contract or if the counterparty does not perform under the contract's terms. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. Realized gains and losses on purchased options are included in realized gains and losses on investment securities, except purchased options on foreign currency which are included in realized gains and losses on foreign currency transactions. If a put option written by the Portfolio is exercised, the premium reduces the cost basis of the securities purchased by the Portfolio. The Portfolio, as a writer of an option, has no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by the dealers. 28 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- For the six months ended June 30, 2006, the Portfolio entered into the following transactions: Number of Written Put Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period 1 $ 55,875 Options written 6 99,936 Options expired (4) (97,726) Options closed (2) (39,702) --------- -------- Outstanding, end of period 1 $18,383 ========= ======== Number of Written Put Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period 1 $ 52,260 Options written 5 129,854 Options expired (3) (42,527) Options closed (1) (52,260) --------- -------- Outstanding, end of period 2 $87,327 ========= ======= At June 30, 2006, the Portfolio held written options. See the Schedule of Investments for further details. Forward currency exchange contracts The Portfolio may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any gains or losses are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Portfolio primarily to protect the value of the Portfolio's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2006, the Portfolio held forward currency exchange contracts. See the Schedule of Investments for further details. Futures contracts The Portfolio may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized gains or losses by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. At June, 30, 2006, the Portfolio held open financial futures contracts. See the Schedule of Investments for further details. 29 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- Swap agreements The Fund may enter into swap agreements. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The Fund may enter into interest rate, credit default and total return swap agreements to manage its exposure to interest rates and credit risk. Interest rate swap agreements involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. In a credit default swap, one party makes a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party on its obligation. The Fund may use credit default swaps to provide a measure of protection against defaults of issuers (i.e., to reduce risk where the Fund owns or has exposure to the corporate or sovereign issuer) or to take an active long or short position with respect to the likelihood of a particular corporate or sovereign issuer's default. Total return swap agreements involve commitments to pay interest in exchange for a market-linked return, both based on notional amounts. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, a fund will receive a payment from or make a payment to the counterparty. In connection with these agreements, cash or securities may be set aside as collateral in accordance with the terms of the swap agreement. Swaps are marked to market daily based upon quotations, which may be furnished by a pricing service or dealers in such securities and the change in value, if any, is recorded as unrealized gain or loss in the Statement of Operations. These financial instruments are not actively traded on financial markets. The values assigned to these instruments are based upon the best available information and because of the uncertainty of the valuation, these values may differ significantly from the values that would have been realized had a ready market for these instruments existed, and differences could be material. Payments received or made at the beginning of the measurement period are reflected as such on the Statement of Assets and Liabilities. Payments received or made from credit default swaps at the end of the measurement period are recorded as realized gain or loss in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gain and loss. Entering into these agreements involves, to varying degrees, elements of credit, market, and documentation risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates. At June 30, 2006, the Fund held open swap agreements. See the Schedule of Investments for further details. (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 loaned securities during the six months ended June 30, 2006 and earned interest on the invested collateral of $1,884,315 of which, $1,848,447 was rebated to borrowers or paid in fees. At June 30, 2006, the Portfolio had securities valued at $46,506,493 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. 30 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (7) Delayed Delivery Transactions: The Portfolio may purchase securities on a when-issued, delayed delivery or forward commitment basis. Payment and delivery may take place a month or more after the date of the transactions. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Income on the securities will not be earned until settlement date. The Portfolio instructs its custodian to segregate securities having value at least equal to the amount of the purchase commitment. The Portfolio may enter into to be announced (TBA) purchase commitments to purchase securities for a fixed unit price at a future date beyond customary settlement time. Although the unit price has been established, the principal value has not been finalized. However, the amount of the commitments will not fluctuate more than 0.01% from the principal amount. The Portfolio holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the Portfolio may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities, according to the procedures described under "Investment security valuations" above. The Portfolio may enter into TBA sale commitments to hedge its portfolio positions. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, an offsetting TBA purchase commitment deliverable is held as "cover" for the transaction. At June 30, 2006, the Portfolio held delayed delivery securities. See the Schedule of Investments for further details. (8) 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. For the six months ended June 30, 2006, the facility fee was $1,810 for the Portfolio. For the six months ended June 30, 2006, the Portfolio did not use the credit facility. 31 Trustees and Officers 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 June 30, 2006.

Mellon Institutional Funds Investment Trust Standish Mellon Global Fixed Income 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 (January 1, 2006 to June 30, 2006). 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 expenses 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 January 1, 2006 January 1, 2006 June 30, 2006 to June 30, 2006 - ------------------------------------------------------------------------------------------------------- Actual $1,000.00 $ 997.70 $3.22 Hypothetical (5% return per year before expenses) $1,000.00 $1,021.57 $3.26 - --------- + Expenses are equal to the Fund's annualized expense ratio of 0.65%, multiplied by the average account value over the period, multiplied by 181/365 (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. 1 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Portfolio Information as of June 30, 2006 (Unaudited) - -------------------------------------------------------------------------------- Summary of Combined Ratings - -------------------------------------------------------------- Percentage of Quality Breakdown Investments - -------------------------------------------------------------- AAA and higher 60.4% AA 3.4 A 13.1 BBB 16.2 BB 4.0 B 2.9 ----- Total 100.0% Based on ratings from Standard & Poor's and/or Moody's Investors Services.

Standish Mellon Global Fixed Income Fund (the "Fund") is a separate non-diversified investment series of the Trust. The Fund invests all its investable assets in an interest of Standish Mellon Global Fixed Income Portfolio (the "Portfolio"), a subtrust of the Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust and has the same investment objective as the Fund. The Portfolio seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in U.S. dollar and non-U.S. dollar denominated fixed income securities of governments and companies located in various countries, including emerging markets. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio (100% at June 30, 2006). 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 The Fund records its investment 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 Securities transactions in the Portfolio are recorded as of the trade date. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all 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 will be declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences which may result in reclassifications, are primarily due to differing treatments for losses deferred due to wash sales, foreign currency gains and losses, post-October losses, amortization and/or accretion of premiums and discounts on certain securities and the timing of recognition of gains and losses on futures contracts. Permanent book and tax basis differences 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. 7 Mellon Institutional Funds Investment Trust Standish Mellon Global Fixed Income Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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. E. Commitments and contingencies In the normal course of business, the Fund may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Fund under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risks of loss to be remote. (2) Investment Advisory Fee 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 Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, for such services. See Note 2 of the Portfolio's Notes to Financial Statements which are included elsewhere in this report. Standish Mellon voluntarily agreed to limit the total operating expenses of the Fund and its pro rata share of the Portfolio expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.65% of the Fund's average daily net assets. Pursuant to this agreement, for the six months ended June 30, 2006, Standish Mellon voluntarily reimbursed the Fund for $38,070 of its operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Fund 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 $2,842 during the six months ended June 30, 2006.

Standish Mellon Global Fixed Income Portfolio (the "Portfolio") is a separate non-diversified investment series of the Portfolio Trust. The objective of the Portfolio is to maximize total return while realizing a market level of income consistent with preserving principal and liquidity. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of its net assets in U.S. dollar and non-U.S. dollar denominated fixed income securities of governments and companies located in various countries, including emerging markets. At June 30, 2006 there was one fund, Standish Mellon Global Fixed Income Fund (the "Fund"), invested in the Portfolio. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. The Fund's proportionate interest at June 30, 2006 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 quoted bid price. 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. 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. 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 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 disregarded entity 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. 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. 22 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- D. Foreign currency transactions The Portfolio maintains its 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. 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 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. H. Affiliated issuers 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. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory, administrative services, and general office facilities is paid monthly at the annual rate of 0.40% of the Portfolio's average daily net assets. Standish Mellon voluntarily agreed to limit the total operating expenses of the Fund and it's pro rata share of the Portfolio expenses (excluding commissions, taxes and extraordinary expenses) to 0.65% of the Fund's average daily net assets The Portfolio has 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 fund 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 $49,263 during the six months ended June 30, 2006. The Portfolio 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 collected $1,922 for the six months ended June 30, 2006. See Note 6 for further details. 23 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. No other director, officer or employee of Standish Mellon or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust or the Portfolio Trust. The Fund and Portfolio Trust pays each Trustee who is not a director, officer or employee of Standish Mellon 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 June 30, 2006 were as follows: Purchases Sales ----------- ----------- U.S. Government Securities $12,214,474 $ 7,893,098 =========== =========== Investments (non-U.S. Government Securities) $18,273,290 $26,413,265 =========== =========== (4) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2006, as computed on a federal income tax basis, were as follows: Aggregate cost $75,692,058 =========== Gross unrealized appreciation 1,041,240 Gross unrealized depreciation (1,478,266) ------------ Net unrealized appreciation (depreciation) $ (437,026) ============ (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: Options Call and put options give the holder the right to purchase or sell a security or currency or enter into a swap arrangement on a future date at a specified price. The Portfolio may use options to seek to hedge against risks of market exposure and changes in security prices and foreign currencies, as well as to seek to enhance returns. Writing puts and buying calls tend to increase the Portfolio's exposure to the underlying instrument. Buying puts and writing calls tend to decrease the Portfolio's exposure to the underlying instrument, or hedge other Portfolio investments. Options, both held and written by the Portfolio, are reflected in the accompanying Statement of Assets and Liabilities at market value. The underlying face amount at value of any open purchased option is shown in the Schedule of Investments. This amount reflects each contract's exposure to the underlying instrument at year end. Losses may arise from changes in the value of the underlying instruments if there is an illiquid secondary market for the contract or if the counterparty does not perform under the contract's terms. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. Realized gains and losses on purchased options are included in realized gains and losses on investment securities, except purchased options on foreign currency which are included in realized gains and losses on foreign currency transactions. If a put option written by the Portfolio is exercised, the premium reduces the cost basis of the securities purchased by the Portfolio. The Portfolio, as a writer of an option, has no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by the dealers. 24 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) For the six months ended June 30, 2006, the Portfolio entered into the following transactions: Number of Written Put Option Transactions Contracts Premiums Outstanding, beginning of period 3 $ 45,440 Options written 5 9,976 Options expired (7) (41,713) Options closed (1) (13,703) ---- -------- Outstanding, end of period 0 $ 0 ==== ======== Number of Written Call Option Transactions Contracts Premiums Outstanding, beginning of period 1 $ 6,958 Options written 3 27,703 Options expired (2) (7,988) Options closed 0 0 ---- -------- Outstanding, end of period 2 $ 26,673 ==== ======== At June 30, 2006, the Portfolio held options. See the Schedule of Investments for further details. Forward currency exchange contracts The Portfolio may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any gains or losses are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Portfolio primarily to protect the value of the Portfolio's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2006, the Portfolio held forward currency exchange contracts. See the Schedule of Investments for further details. Futures contracts The Portfolio may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized gains or losses by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. At June, 30, 2006, the Portfolio held open financial futures contracts. See the Schedule of Investments for further details. 25 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- Swap agreements The Portfolio may enter into swap agreements. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The Portfolio may enter into interest rate, credit default and total return swap agreements to manage its exposure to interest rates and credit risk. Interest rate swap agreements involve the exchange by the Portfolio with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. In a credit default swap, one party makes a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party on its obligation. The Portfolio may use credit default swaps to provide a measure of protection against defaults of issuers (i.e., to reduce risk where the Portfolio owns or has exposure to the corporate or sovereign issuer) or to take an active long or short position with respect to the likelihood of a particular corporate or sovereign issuer's default. Total return swap agreements involve commitments to pay interest in exchange for a market-linked return, both based on notional amounts. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, a portfolio will receive a payment from or make a payment to the counterparty. In connection with these agreements, cash or securities may be set aside as collateral in accordance with the terms of the swap agreement. Swaps are marked to market daily based upon quotations, which may be furnished by a pricing service or dealers in such securities and the change in value, if any, is recorded as unrealized gain or loss in the Statement of Operations. These financial instruments are not actively traded on financial markets. The values assigned to these instruments are based upon the best available information and because of the uncertainty of the valuation, these values may differ significantly from the values that would have been realized had a ready market for these instruments existed, and differences could be material. Payments received or made at the beginning of the measurement period are reflected as such on the Statement of Assets and Liabilities. Payments received or made from credit default swaps at the end of the measurement period are recorded as realized gain or loss in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gain and loss. Entering into these agreements involves, to varying degrees, elements of credit, market, and documentation risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates. At June 30, 2006, the Portfolio held open swap agreements. See the Schedule of Investments for further details. (6) Security Lending: The Portfolio may lend its securities to financial institutions which the Portfolio deems to be creditworthy. The loans are collateralized at all times with cash or securities with a market value at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is allocated to the Portfolio on the next business day. For the duration of a loan, the Portfolio receives the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives compensation from the investment of the collateral. As with other extensions of credit, the Portfolio bears the risk of delay in recovery or even loss of rights in its securities on loan should the borrower of the securities fail financially or default on its obligations to the Portfolio. In the event of borrower default, the Portfolio generally has the right to use the collateral to offset losses incurred. The Portfolio may incur a loss in the event it was delayed or prevented from exercising its rights to dispose of the collateral. The Portfolio also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Portfolio's obligations due on the loans. The Portfolio loaned securities during the six months ended June 30, 2006 and earned interest on the invested collateral of $279,357 of which, $274,888 was rebated to borrowers or paid in fees. At June 30, 2006, the Portfolio had securities valued at $7,373,211 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. (7) Delayed Delivery Transactions: The Portfolio may purchase securities on a when-issued, delayed delivery or forward commitment basis. Payment and delivery may take place a month or more after the date of the transactions. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Income on the securities will not be earned until settlement date. The Portfolio instructs its custodian to segregate securities having value at least equal to the amount of the purchase commitment. The Portfolio may enter into to be announced (TBA) purchase commitments to purchase securities for a fixed unit price at a future date beyond customary settlement time. Although the unit price has been established, the principal value has not been finalized. However, the amount of the commitments will not fluctuate more than 0.01% from the principal amount. The Portfolio holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the Portfolio may enter into offsetting contracts for the forward sale of 26 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities, according to the procedures described under "Investment security valuations" above. The Portfolio may enter into TBA sale commitments to hedge its portfolio positions. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, an offsetting TBA purchase commitment deliverable is held as "cover" for the transaction. For the six months ended June 30, 2006, the Portfolio did not hold any delayed delivery securities. (8) 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. For the six months ended June 30, 2006, the facility fee was $317 for the Portfolio. For the six months ended June 30, 2006, the Portfolio did not use the credit facility. 27 Trustees and Officers 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 June 30, 2006.

Mellon Institutional Funds Investment Trust Standish Mellon High Yield 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 (January 1, 2006 to June 30, 2006). 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 expenses 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 January 1, 2006 January 1, 2006 June 30, 2006 to June 30, 2006 - ---------------------------------------------------------------------------------------------- Actual $1,000.00 $1,012.10 $2.49 Hypothetical (5% return per year before expenses) $1,000.00 $1,022.32 $2.51 - --------- + Expenses are equal to the Fund's annualized expense ratio of 0.50%, multiplied by the average account value over the period, multiplied by 181/365 (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. 1 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond Fund Portfolio Information as of June 30, 2006 (Unaudited) - -------------------------------------------------------------------------------- Summary of Combined Ratings Percentage of Quality Breakdown Investments - ------------------------------------------------------------- Treasury 1.0% AA 0.1 A 1.2 BBB 11.7 BB 46.2 B 37.9 CCC 1.6 C/D/NR 0.3 ----- Total 100.0% Based on ratings from Standard & Poor's and/or Moody's Investors Services.

Standish Mellon High Yield Bond Fund (the "Fund") is a separate diversified investment series of the Trust. The Fund invests all of its investable assets in an interest in the Standish Mellon High Yield Bond Portfolio (the "Portfolio"), a subtrust of the Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust and 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 below investment grade fixed income securities issued by U.S. and foreign governments, companies and banks, as well as tax-exempt securities, preferred stocks and warrants. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio (100% at June 30, 2006). 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 The Fund records its investment 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 Securities transactions in the Portfolio are recorded as of the trade date. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all 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 will be declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences which may result in reclassifications, are primarily due to differing treatments for losses deferred due to wash sales, foreign currency gains and losses, post-October losses, amortization and/or accretion of premiums and discounts on certain securities and the timing of recognition of gains and losses on futures contracts. Permanent book and tax basis differences 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. 7 Mellon Institutional Funds Investment Trust Standish Mellon High Yield 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. (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 Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, for such services. See Note 2 of the Portfolio's Notes to Financial Statements which are included elsewhere in this report. Standish Mellon voluntarily agreed to limit the total operating expenses of the Fund and its pro rata share of the Portfolio expenses (excluding commissions, taxes and extraordinary expenses) to 0.50% of the Fund's average daily net assets. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. Pursuant to this agreement, for the six months ended June 30, 2006, Standish Mellon voluntarily reimbursed the Fund for $34,509 of its operating expenses. The Fund 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 $3,410 during the six months ended June 30, 2006. The Fund 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 $617 during the six months ended June 30, 2006. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2006, the Fund was charged $1,945. No other director, officer or employee of Standish Mellon or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust or the Portfolio Trust. The Fund pays each Trustee who is not a director, officer or employee of Standish Mellon 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 June 30, 2006, the Fund was charged $667 for fees payable to Mellon Private Wealth Management. (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended June 30, 2006, aggregated $1,060,401and $5,694,398, respectively. The Fund receives a proportionate share of the Portfolio's income, expenses, 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. 8 Mellon Institutional Funds Investment Trust Standish Mellon High Yield Bond 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 For the Six Months Ended Year Ended June 30, 2006 December 31, 2005 ------------- ----------------- Shares sold 38,522 257,259 Shares issued to shareholders in reinvestment of distributions 24,283 104,233 Shares redeemed (321,905) (2,681,089) -------- ---------- Net increase (decrease) (259,100) 2,319,597 ======== ========== At June 30, 2006, two shareholders of record held approximately 61% 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 their 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 June 30, 2006, the Fund received $159 in redemption fees. (5) Federal Taxes: As a regulated investment company qualified under Subchapter M of the Internal Revenue Code, the Fund is not subject to income taxes to the extent that it distributes substantially all of its taxable income for its fiscal year. See corresponding master portfolio for tax basis unrealized appreciation (depreciation) information. 9 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond Portfolio Schedule of Investments -- June 30, 2006 (Unaudited) - -------------------------------------------------------------------------------- Par Value Security Description Rate Maturity Value (Note 1A) - --------------------------------------------------------------------------------------------------------------------------------- UNAFFILIATED INVESTMENTS--105.3% BONDS AND NOTES--95.9% Convertible Corporate Bonds--0.5% Centerpoint Energy, Inc. 144A CVT 2.875% 1/15/2024 $ 25,000 $ 26,000 Sinclair Broadcast Group, Inc.

Standish Mellon High Yield Bond Portfolio (the "Portfolio") is a separate diversified investment series of the Portfolio Trust. The objective of the Portfolio is to maximize total return, consisting primarily of a high level of income. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in below investment grade fixed income securities issued by U.S. and foreign governments, companies and banks, as well as tax-exempt securities, preferred stocks and warrants. At June 30, 2006 there was one fund, Standish Mellon High Yield Bond Fund (the "Fund"), invested in the Portfolio. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. The Fund's proportionate interest at June 30, 2006 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 quoted bid price. 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. 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. 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 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 disregarded entity 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. 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. 21 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- D. Foreign currency transactions The Portfolio maintains its 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. 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 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. H. Affiliated issuers 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. (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 0.50% of the Portfolio's average daily net assets. Standish Mellon voluntarily agreed to limit the Portfolio's total annual operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.50% of the Portfolio's average daily net assets for the six months ended June 30, 2006. Pursuant to this agreement, for the six months ended June 30, 2006, Standish Mellon voluntarily waived all of its investment advisory fee in the amount of $35,369 and reimbursed the Portfolio $7,785. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Portfolio has entered into an agreement 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 fund 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 $22,029 during the six months ended June 30, 2006. The Portfolio 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 collected $513 for the six months ended June 30, 2006. See Note 6 for further details. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. No other director, officer or employee of Standish Mellon or its affiliates received any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust or the Portfolio Trust. The Fund and Portfolio Trust pays each Trustee who is not a director, officer or employee of Standish Mellon 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. 22 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond Portfolio 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 June 30, 2006 were as follows: Purchases Sales ---------- ---------- Investments (non-U.S. Government Securities) $2,740,220 $5,611,416 ========== ========== (4) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2006, as computed on a federal income tax basis, were as follows: Aggregate cost $ 14,273,229 ============ Gross unrealized appreciation $ 274,490 Gross unrealized depreciation (269,298) ============ Net unrealized appreciation (depreciation) 5,192 ============ (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: Options Call and put options give the holder the right to purchase or sell a security or currency or enter into a swap arrangement on a future date at a specified price. The Portfolio may use options to seek to hedge against risks of market exposure and changes in security prices and foreign currencies, as well as to seek to enhance returns. Writing puts and buying calls tend to increase the Portfolio's exposure to the underlying instrument. Buying puts and writing calls tend to decrease the Portfolio's exposure to the underlying instrument, or hedge other Portfolio investments. Options, both held and written by the Portfolio, are reflected in the accompanying Statement of Assets and Liabilities at market value. The underlying face amount at value of any open purchased option is shown in the Schedule of Investments. This amount reflects each contract's exposure to the underlying instrument at year end. Losses may arise from changes in the value of the underlying instruments if there is an illiquid secondary market for the contract or if the counterparty does not perform under the contract's terms. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. Realized gains and losses on purchased options are included in realized gains and losses on investment securities, except purchased options on foreign currency which are included in realized gains and losses on foreign currency transactions. If a put option written by the Portfolio is exercised, the premium reduces the cost basis of the securities purchased by the Portfolio. The Portfolio, as a writer of an option, has no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by the dealers. The Portfolio did not enter into any options contracts during the six months ended June 30, 2006. 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 23 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- currency and any gains or losses are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Portfolio primarily to protect the value of the Portfolio's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2006, the Portfolio held open forward currency exchange contracts. See the Schedule of Investments for further details. Futures contracts The Portfolio may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized gains or losses by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. The Portfolio did not enter into any futures contracts for the six months ended June 30, 2006. Swap agreements The Fund may enter into swap agreements. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The Fund may enter into interest rate, credit default and total return swap agreements to manage its exposure to interest rates and credit risk. Interest rate swap agreements involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. In a credit default swap, one party makes a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party on its obligation. The Fund may use credit default swaps to provide a measure of protection against defaults of issuers (i.e., to reduce risk where the Fund owns or has exposure to the corporate or sovereign issuer) or to take an active long or short position with respect to the likelihood of a particular corporate or sovereign issuer's default. Total return swap agreements involve commitments to pay interest in exchange for a market-linked return, both based on notional amounts. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, a fund will receive a payment from or make a payment to the counterparty. In connection with these agreements, cash or securities may be set aside as collateral in accordance with the terms of the swap agreement. Swaps are marked to market daily based upon quotations, which may be furnished by a pricing service or dealers in such securities and the change in value, if any, is recorded as unrealized gain or loss in the Statement of Operations. These financial instruments are not actively traded on financial markets. The values assigned to these instruments are based upon the best available information and because of the uncertainty of the valuation, these values may differ significantly from the values that would have been realized had a ready market for these instruments existed, and differences could be material. Payments received or made at the beginning of the measurement period are reflected as such on the Statement of Assets and Liabilities. Payments received or made from credit default swaps at the end of the measurement period are recorded as realized gain or loss in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gain and loss. Entering into these agreements involves, to varying degrees, elements of credit, market, and documentation risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates. At June 30, 2006, the Fund held open swap agreements. See the Schedule of Investments for further details. 24 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond 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 loaned securities during the six months ended June 30, 2006 and earned interest on the invested collateral of $24,353 of which, $23,139 was rebated to borrowers or paid in fees. At June 30, 2006, the Portfolio had securities valued at $1,028,623 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. (7) Delayed Delivery Transactions: The Portfolio may purchase securities on a when-issued, delayed delivery or forward commitment basis. Payment and delivery may take place a month or more after the date of the transactions. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Income on the securities will not be earned until settlement date. The Portfolio instructs its custodian to segregate securities having value at least equal to the amount of the purchase commitment. The Portfolio may enter into to be announced (TBA) purchase commitments to purchase securities for a fixed unit price at a future date beyond customary settlement time. Although the unit price has been established, the principal value has not been finalized. However, the amount of the commitments will not fluctuate more than 0.01% from the principal amount. The Portfolio holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the Portfolio may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities, according to the procedures described under "Investment security valuations" above. The Portfolio may enter into TBA sale commitments to hedge its portfolio positions. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, an offsetting TBA purchase commitment deliverable is held as "cover" for the transaction. The Portfolio did not enter into any delayed delivery securities during the period ended June 30, 2006. (8) 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. For the six months ended June 30, 2006, the facility fee was $961 for the Portfolio. For the six months ended June 30, 2006, the Portfolio had average borrowings outstanding of $341,300 for a total of twenty days and incurred $198 of interest expense. 25 Trustees and Officers 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 June 30, 2006.

Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income 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 (January 1, 2006 to June 30, 2006). 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 expenses 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 January 1, 2006 January 1, 2006 June 30, 2006 to June 30, 2006 - ------------------------------------------------------------------------------------------------------------------------------------ Actual $1,000.00 $ 991.60 $3.21 Hypothetical (5% return per year before expenses) $1,000.00 $1,021.57 $3.26 - ------------- + Expenses are equal to the Fund's annualized expense ratio of 0.65%, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 1 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund Portfolio Information as of June 30, 2006 (Unaudited) - -------------------------------------------------------------------------------- Summary of Combined Ratings - -------------------------------------------------------------------- Percentage of Quality Breakdown Investments - -------------------------------------------------------------------- AAA and higher 68.0% AA 3.3 A 12.3 BBB 11.1 BB 3.6 B 1.7 ---- Total 100.0% Based on ratings from Standard & Poor's and/or Moody's Investors Services.

Standish Mellon International Fixed Income Fund (the "Fund") is a separate diversified investment series of the Trust. The objective of the Fund is to maximize total return while realizing a market level of income consistent with preserving principal and liquidity. The Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in fixed income securities, and at least 65% of net assets in non-U.S. dollar denominated fixed income securities of foreign governments and companies located in various countries, including emerging markets. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities 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 quoted bid price. 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. 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. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. The Fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. Net realized gains and losses on foreign currency transactions represent gains and losses on disposition of foreign currencies and forward foreign currency exchange contracts, currency gains and losses realized between the trade and settlement dates on securities transactions, and the difference between the amount of investment income and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent amounts actually received or paid. C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. 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, amortization and/or accretion of premiums and discounts on certain securities, capital loss carryforwards and the timing of recognition of gains and losses on futures contracts. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income(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. 13 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- D. Foreign currency transactions The Fund maintains its 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. 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. 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. 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 Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. (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 payable monthly at the annual rate of 0.40% of the Fund's average daily net assets. The Fund 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 $0 during the six months ended June 30, 2006. The Fund has 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, fund administration and accounting services for the Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement the Fund was charged $50,872 during the six months ended June 30, 2006. The Fund 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 collected $1,159 for the six months ended June 30, 2006. See Note 7 for further details. The Fund 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 $2,048 during the six months ended June 30, 2006. 14 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income 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 June 30, 2006, the Fund was charged $1,933. 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 Trust pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee and a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Trust pays the legal fees for the independent counsel of the Trustees. 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 June 30, 2006, the Fund was charged $14,506 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 June 30, 2006 were as follows: Purchases Sales ----------- ----------- U.S. Government Securities $ 9,221,091 $12,531,526 =========== =========== Investments (non-U.S. Government Securities) $51,349,402 $56,379,851 =========== =========== (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 June 30, 2006 December 31, 2005 ---------------- ----------------- Shares sold 404,885 1,676,512 Shares issued to shareholders reinvestment of distributions declared 55,849 1,578,442 Shares redeemed (900,085) (10,425,328) ----------- ----------- Net increase (decrease) (439,351) 7,170,374 =========== =========== At June 30, 2006, four shareholders of record held approximately 64% 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 June 30, 2006, the Fund did not collect any redemption fees. (5) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2006, as computed on a federal income tax basis, were as follows: Aggregate cost $115,231,320 ============ Gross unrealized appreciation 1,813,414 Gross unrealized depreciation (1,864,629) ------------ Net unrealized appreciation (depreciation) $(51,215) ============ 15 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income 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 instruments with off-balance sheet risk: Options Call and put options give the holder the right to purchase or sell a security or currency or enter into a swap arrangement on a future date at a specified price. The Fund may use options to seek to hedge against risks of market exposure and changes in security prices and foreign currencies, as well as to seek to enhance returns. Writing puts and buying calls tend to increase the Fund's exposure to the underlying instrument. Buying puts and writing calls tend to decrease the Fund's exposure to the underlying instrument, or hedge other Fund investments. Options, both held and written by the Fund, are reflected in the accompanying Statement of Assets and Liabilities at market value. The underlying face amount at value of any open purchased option is shown in the Schedule of Investments. This amount reflects each contract's exposure to the underlying instrument at year end. Losses may arise from changes in the value of the underlying instruments if there is an illiquid secondary market for the contract or if the counterparty does not perform under the contract's terms. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. Realized gains and losses on purchased options are included in realized gains and losses on investment securities, except purchased options on foreign currency which are included in realized gains and losses on foreign currency transactions. If a put option written by the Fund is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund, as a writer of an option, has no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by the dealers. During the six months ended June 30, 2006, the Fund entered into the following transactions: Number of Written Put Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period 3 $126,669 Options written 5 17,012 Options expired (7) (107,542) Options closed (1) (36,139) -------- -------- Outstanding, end of period 0 $ -- ======== ======== Number of Written Call Option Transactions Contracts Premiums Outstanding, beginning of period 1 $18,351 Options written 3 46,375 Options expired (2) (20,077) -------- -------- Outstanding, end of period 2 $44,649 ======== ======== At June 30, 2006, the Fund held options. See the Schedule of Investments for further details. 16 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income 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 gains or losses are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Fund primarily to protect the value of the Fund's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2006, the Fund held currency exchange contracts. See the Schedule of Investments for further details. Futures contracts The Fund may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Fund deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the Fund each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized gains or losses by the Fund. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Fund's exposure to the underlying instrument, while selling futures tends to decrease the Fund's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the 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 June 30, 2006, the Fund held futures contracts. See the Schedule of Investments for further details. Swap agreements The Fund may enter into swap agreements. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The Fund may enter into interest rate, credit default and total return swap agreements to manage its exposure to interest rates and credit risk. Interest rate swap agreements involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. In a credit default swap, one party makes a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party on its obligation. The Fund may use credit default swaps to provide a measure of protection against defaults of issuers (i.e., to reduce risk where the Fund owns or has exposure to the corporate or sovereign issuer) or to take an active long or short position with respect to the likelihood of a particular corporate or sovereign issuer's default. Total return swap agreements involve commitments to pay interest in exchange for a market-linked return, both based on notional amounts. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, a fund will receive a payment from or make a payment to the counterparty. In connection with these agreements, cash or securities may be set aside as collateral in accordance with the terms of the swap agreement. Swaps are marked to market daily based upon quotations, which may be furnished by a pricing service or dealers in such securities and the change in value, if any, is recorded as unrealized gain or loss in the Statement of Operations. These financial instruments are not actively traded on financial markets. The values assigned to these instruments are based upon the best available information and because of the uncertainty of the valuation, these values may differ significantly from the values that would have been realized had a ready market for these instruments existed, and differences could be material. Payments received or made at the beginning of the measurement period are reflected as such on the Statement of Assets and Liabilities. Payments received or made from credit default swaps at the end of the measurement period are recorded as realized gain or loss in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gain and loss. Entering into these agreements involves, to varying degrees, elements of credit, market, and documentation risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates. At June 30, 2006, the Fund held open swap agreements. See the Schedule of Investments for further details. 17 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (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 loaned securities during the six months ended June 30, 2006 and earned interest on the invested collateral of $203,772 of which, $201,050 was rebated to borrowers or paid in fees. At June 30, 2006, the Fund had securities valued at $786,952 on loan. See the 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.

Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Shareholder Expense Example (Unaudited) - -------------------------------------------------------------------------------- As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (January 1, 2006 to June 30, 2006). 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 expenses 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 January 1, 2006 January 1, 2006 June 30, 2006 to June 30, 2006 - ----------------------------------------------------------------------------------------------------------------------------------- Actual $1,000.00 $1,034.50 $3.78 Hypothetical (5% return per year before expenses) $1,000.00 $1,021.08 $3.76 - --------- + Expenses are equal to the Fund's annualized expense ratio of 0.75%, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 1 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Portfolio Information as of June 30, 2006 (Unaudited) - -------------------------------------------------------------------------------- Summary of Combined Ratings - ------------------------------------------------------------------------- Percentage of Quality Breakdown Investments - ------------------------------------------------------------------------- AAA and higher 72.6% AA 1.7 A 13.1 BBB 7.6 BB 3.4 B 1.6 ----- Total 100.0% Based on ratings from Standard & Poor's and/or Moody's Investors Services.

Standish Mellon International Fixed Income II Fund (the "Fund") is a separate diversified investment series of the Trust. The objective of the Fund is to maximize total return while realizing a market level of income consistent with preserving principal and liquidity. The Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in fixed income securities, and at least 65% of net assets in non-U.S. dollar denominated fixed income securities of foreign governments and companies located in various countries, including emerging markets. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities 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 quoted bid price. 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. 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. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. The Fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. Net realized gains and losses on foreign currency transactions represent gains and losses on disposition of foreign currencies and forward foreign currency exchange contracts, currency gains and losses realized between the trade and settlement dates on securities transactions, and the difference between the amount of investment income and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent amounts actually received or paid. C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. 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, amortization and/or accretion of premiums and discounts on certain securities, capital loss carryforwards and the timing of recognition of gains and losses on futures contracts. 13 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income(losses), 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. Foreign currency transactions The Fund maintains its 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. 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. 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. 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 Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. (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 payable monthly at the annual rate of 0.40% of the Fund's average daily net assets. Standish Mellon voluntarily agreed to limit total Fund operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.75% of the Fund's average daily net assets for the six months ended June 30, 2006. Pursuant to this agreement, for the six months ended June 30, 2006, Standish Mellon voluntarily waived a portion of its investment advisory fee in the amount of $45,312. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Fund 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 $3,524 during the six months ended June 30, 2006. 14 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Fund 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 fund accounting services for the Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement the Fund was charged $45,695 during the six months ended June 30, 2006. The Fund 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 collected $725 for the six months ended June 30, 2006. See Note 7 for further details. The Fund 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 $339 during the six months ended June 30, 2006. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2006, the Fund was charged $1,933. 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 Trust pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee and a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Trust pays the legal fees for the independent counsel of the Trustees. 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 June 30, 2006, the Fund was charged $2,183 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 June 30, 2006 were as follows: Purchases Sales ----------- ----------- U.S. Government Securities $ 3,469,486 $ 4,060,947 ============ =========== Investments (non-U.S. Government Securities) $ 21,234,353 $28,070,593 ============ =========== (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 June 30, 2006 December 31, 2005 ---------------- ----------------- Shares sold 318,471 796,615 Shares issued to shareholders reinvestment of distributions declared 7,591 59,347 Shares redeemed (632,690) (719,016) --------- -------- Net increase (decrease) (306,628) 136,946 ========= ======== At June 30, 2006, two shareholders of record held 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 were acquired through reinvestment of distributions. For the six months ended June 30, 2006, the Fund collected $298 in redemption fees. 15 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (5) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2006, as computed on a federal income tax basis, were as follows: Aggregate cost $40,410,201 ----------- Gross unrealized appreciation 471,646 Gross unrealized depreciation (579,045) ----------- Net unrealized appreciation (depreciation) $ (107,399) =========== (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 instruments with off-balance sheet risk: Options Call and put options give the holder the right to purchase or sell a security or currency or enter into a swap arrangement on a future date at a specified price. The Fund may use options to seek to hedge against risks of market exposure and changes in security prices and foreign currencies, as well as to seek to enhance returns. Writing puts and buying calls tend to increase the Fund's exposure to the underlying instrument. Buying puts and writing calls tend to decrease the Fund's exposure to the underlying instrument, or hedge other Fund investments. Options, both held and written by the Fund, are reflected in the accompanying Statement of Assets and Liabilities at market value. The underlying face amount at value of any open purchased option is shown in the Schedule of Investments. This amount reflects each contract's exposure to the underlying instrument at year end. Losses may arise from changes in the value of the underlying instruments if there is an illiquid secondary market for the contract or if the counterparty does not perform under the contract's terms. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. Realized gains and losses on purchased options are included in realized gains and losses on investment securities, except purchased options on foreign currency which are included in realized gains and losses on foreign currency transactions. If a put option written by the Fund is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund, as a writer of an option, has no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by the dealers. During the six months ended June 30, 2006, the Fund entered into the following transactions: Number of Written Put Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period 3 $ 30,176 Options written 4 4,037 Options expired (5) (13,253) Options closed (2) (20,960) ---- ---------- Outstanding, end of period 0 $ -- ==== =========== Number of Written Call Option Transactions Contracts Premiums --------- ======== Outstanding, beginning of period 1 $ 4,680 Options written 3 14,866 Options expired (2) (5,231) Options closed 0 -- --- -------- Outstanding, end of period 2 $ 14,315 === ======== At June 30, 2006, the Fund held written options. See the Schedule of Investments for further details. 16 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II 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 gains or losses are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Fund primarily to protect the value of the Fund's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2006, the Fund held currency exchange contracts. See the Schedule of Investments for further details. Futures contracts The Fund may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Fund deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the Fund each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized gains or losses by the Fund. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Fund's exposure to the underlying instrument, while selling futures tends to decrease the Fund's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the 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 June 30, 2006, the Fund held futures contracts. See the Schedule of Investments for further details. Swap agreements The Fund may enter into swap agreements. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The Fund may enter into interest rate, credit default and total return swap agreements to manage its exposure to interest rates and credit risk. Interest rate swap agreements involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. In a credit default swap, one party makes a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party on its obligation. The Fund may use credit default swaps to provide a measure of protection against defaults of issuers (i.e., to reduce risk where the Fund owns or has exposure to the corporate or sovereign issuer) or to take an active long or short position with respect to the likelihood of a particular corporate or sovereign issuer's default. Total return swap agreements involve commitments to pay interest in exchange for a market-linked return, both based on notional amounts. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, a fund will receive a payment from or make a payment to the counterparty. In connection with these agreements, cash or securities may be set aside as collateral in accordance with the terms of the swap agreement. Swaps are marked to market daily based upon quotations, which may be furnished by a pricing service or dealers in such securities and the change in value, if any, is recorded as unrealized gain or loss in the Statement of Operations. These financial instruments are not actively traded on financial markets. The values assigned to these instruments are based upon the best available information and because of the uncertainty of the valuation, these values may differ significantly from the values that would have been realized had a ready market for these instruments existed, and differences could be material. Payments received or made at the beginning of the measurement period are reflected as such on the Statement of Assets and Liabilities. Payments received or made from credit default swaps at the end of the measurement period are recorded as realized gain or loss in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gain and loss. Entering into these agreements involves, to varying degrees, elements of credit, market, and documentation risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates. At June 30, 2006, the Fund held open swap agreements. See the Schedule of Investments for further details. 17 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (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 loaned securities during the six months ended June 30, 2006 and earned interest on the invested collateral of $68,163, of which $66,468 was rebated to borrowers or paid in fees. At June 30, 2006, the Fund had securities valued at $837,565 on loan. See the 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. For six months ended June 30, 2006, the facility fee was $786 for the Fund. For the six months ended June 30, 2006, the Fund had average borrowings outstanding of $2,194,250 on a total of four days and incurred $1,274 of interest expense. 18 Trustees and Officers 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 June 30, 2006.

Mellon Institutional Funds Investment Trust Standish Mellon Investment Grade 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 (January 1, 2006 to June 30, 2006). 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 expenses 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 January 1, 2006 January 1, 2006 June 30, 2006 to June 30, 2006 - --------------------------------------------------------------------------------------------------------- Actual $1,000.00 $ 992.00 $1.98 Hypothetical (5% return per year before expenses) $1,000.00 $1,022.81 $2.01 - ------- + Expenses are equal to the Fund's annualized expense ratio of 0.40%, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 1 Mellon Institutional Funds Investment Trust Standish Mellon Investment Grade Bond Fund Portfolio Information as of June 30, 2006 (Unaudited) - -------------------------------------------------------------------------------- Summary of Combined Ratings - -------------------------------------------------------------------------------- Percentage of Quality Breakdown Investments - -------------------------------------------------------------------------------- AAA & Higher 53.0% AA 11.0 A 12.5 BBB 23.5 ----- Total 100.0% Based on ratings from Standard & Poor's and/or Moody's Investors Services.

Standish Mellon Investment Grade Bond Fund (the "Fund") is a separate diversified investment series of the Trust. The objective of the Fund is to maximize total return, consistent with preserving principal and liquidity, primarily through the generation of current income and, to a lesser extent, capital appreciation. The Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in investment grade fixed income securities including, but not limited to, government, agency, corporate and mortgage and asset-backed issues. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities 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 quoted bid price. 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. 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. 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. 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 amortization and/or accretion of premiums and discounts on certain securities and the timing of recognition of gains and losses on futures contracts. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income, accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (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. 16 Mellon Institutional Funds Investment Trust Standish Mellon Investment Grade 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 issuers 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. (2) Investment Advisory Fee and Other Transactions With Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory, administrative services, and general office facilities, is payable monthly at the annual rate of 0.40% of the Fund's average daily net assets. Standish Mellon voluntarily agreed to limit total Fund operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.40% of the Fund's average daily net assets for the six months ended June 30, 2006. Pursuant to this agreement, for the six months ended June 30, 2006, Standish Mellon voluntarily waived its investment advisory fee in the amount of $17,769 and reimbursed the Fund $48,032 for other operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Fund 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 $2,688 during the six months ended June 30, 2006. The Fund 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 fund accounting services for the Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement the Fund was charged $26,522 during the six months ended June 30, 2006. The Fund 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 collected $103 for the six months ended June 30, 2006. See Note 7 for further details. The Fund 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. The Fund was not charged for printing and fulfillment services during the six months ended June 30, 2006. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2006, the Fund was charged $1,979. 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 Trust pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee and a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Trust pays the legal fees for the independent counsel of the Trustees. 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 June 30, 2006, the Fund did not pay an administrative service fee to Mellon Private Wealth Management. 17 Mellon Institutional Funds Investment Trust Standish Mellon Investment Grade Bond 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 June 30, 2006 were as follows: Purchases Sales ----------- ----------- U.S. Government Securities $ 5,354,624 $ 5,111,672 =========== =========== Investments (non-U.S. Government Securities) $ 1,412,359 $ 611,707 =========== =========== (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 June 30, 2006 December 31, 2005 ---------------- ----------------- Shares sold 10,343 261,106 Shares issued to shareholders reinvestment of distributions declared 10,511 48,779 Shares redeemed (47,068) (2,402,674) ------- ---------- Net increase (decrease) (26,214) (2,092,789) ======= ========== At June 30, 2006, two shareholders of record held approximately 97.1% of the total outstanding shares of the Fund. Investment activities of these shareholders could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended June 30, 2006, the Fund did not collect any redemption fees. (5) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2006, as computed on a federal income tax basis, were as follows: Aggregate cost $ 11,010,342 ============ Gross Unrealized appreciation 6,883 Gross Unrealized depreciation (312,721) ------------ Net unrealized appreciation/(depreciation) $ (305,838) ============ (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 instruments with off-balance sheet risk: Options Call and put options give the holder the right to purchase or sell a security or currency or enter into a swap arrangement on a future date at a specified price. The Fund may use options to seek to hedge against risks of market exposure and changes in security prices and foreign currencies, as well as to seek to enhance returns. Writing puts and buying calls tend to increase the Fund's exposure to the underlying instrument. Buying puts and writing calls tend to decrease the Fund's exposure to the underlying instrument, or hedge other Fund investments. Options, both held and written by 18 Mellon Institutional Funds Investment Trust Standish Mellon Investment Grade Bond Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- the Fund, are reflected in the accompanying Statement of Assets and Liabilities at market value. The underlying face amount at value of any open purchased option is shown in the Schedule of Investments. This amount reflects each contract's exposure to the underlying instrument at year end. Losses may arise from changes in the value of the underlying instruments if there is an illiquid secondary market for the contract or if the counterparty does not perform under the contract's terms. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. Realized gains and losses on purchased options are included in realized gains and losses on investment securities, except purchased options on foreign currency which are included in realized gains and losses on foreign currency transactions. If a put option written by the Fund is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund, as a writer of an option, has no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by the dealers. During the six months ended June 30, 2006, the Fund entered into the following transactions: Number of Written Put Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period 1 $ 1,188 Options written 4 1,819 Options expired (2) (1,813) Options closed (2) (839) --------- -------- Outstanding, end of period 1 $ 355 ========= ======== Number of Written Call Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period 0 $ 0 Options written 1 267 Options expired (1) (267) Options closed 0 0 --------- -------- Outstanding, end of period 0 $ 0 ========= ======== At June 30, 2006, the Fund held written options. See the Schedule of Investments for further details. Futures contracts The Fund may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Fund deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the Fund each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized gains or losses by the Fund. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Fund's exposure to the underlying instrument, while selling futures tends to decrease the Fund's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the 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 June 30, 2006, the Fund held open financial futures contracts. See the Schedule of Investments for further details. 19 Mellon Institutional Funds Investment Trust Standish Mellon Investment Grade Bond Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- Swap Agreements The Fund may enter into swap agreements. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The Fund may enter into interest rate, credit default and total return swap agreements to manage its exposure to interest rates and credit risk. Interest rate swap agreements involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. In a credit default swap, one party makes a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party on its obligation. The Fund may use credit default swaps to provide a measure of protection against defaults of issuers (i.e., to reduce risk where the Fund owns or has exposure to the corporate or sovereign issuer) or to take an active long or short position with respect to the likelihood of a particular corporate or sovereign issuer's default. Total return swap agreements involve commitments to pay interest in exchange for a market-linked return, both based on notional amounts. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, a fund will receive a payment from or make a payment to the counterparty. In connection with these agreements, cash or securities may be set aside as collateral in accordance with the terms of the swap agreement. Swaps are marked to market daily based upon quotations, which may be furnished by a pricing service or dealers in such securities, and the change in value, if any, is recorded as unrealized gain or loss in the Statement of Operations. These financial instruments are not actively traded on financial markets. The values assigned to these instruments are based upon the best available information and because of the uncertainty of the valuation, these values may differ significantly from the values that would have been realized had a ready market for these instruments existed, and differences could be material. Payments received or made at the beginning of the measurement period are reflected as such on the Statement of Assets and Liabilities. Payments received or made from credit default swaps at the end of the measurement period are recorded as realized gain or loss in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gain and loss. Entering into these agreements involves, to varying degrees, elements of credit, market, and documentation risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates. At June 30, 2006, the Fund held open swap agreements. 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 loaned securities during the six months ended June 30, 2006 and earned interest on the invested collateral of $13,579 of which, $13,323 was rebated to borrowers or paid in fees. At June 30, 2006, the Fund had securities valued at $474,732 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. (8) Delayed Delivery Transactions: The Fund may purchase securities on a when-issued, delayed delivery or forward commitment basis. Payment and delivery may take place a month or more after the date of the transactions. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Income on the securities will not be earned until settlement date. The Fund instructs its custodian to segregate securities having value at least equal to the amount of the purchase commitment. 20 Mellon Institutional Funds Investment Trust Standish Mellon Investment Grade Bond Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Fund may enter into to be announced (TBA) purchase commitments to purchase securities for a fixed unit price at a future date beyond customary settlement time. Although the unit price has been established, the principal value has not been finalized. However, the amount of the commitments will not fluctuate more than 0.01% from the principal amount. The Fund holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the Fund may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities, according to the procedures described under "Investment security valuations" above. The Portfolio may enter into TBA sale commitments to hedge its portfolio positions. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, an offsetting TBA purchase commitment deliverable is held as "cover" for the transaction. For six months ended June 30, 2006, the Fund held delayed delivery securities. See the Schedule of Investments for further details. (9) 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 six months ended June 30, 2006, the facility fee was $0 for the Fund. For the six months ended June 30, 2006, the Fund did not borrow from the credit facility. (10) Subsequent Event: In response to total redemption requests submitted by the Fund's remaining shareholders, the Fund began the process of dissolving and winding up its business. On July 14, 2006 the Fund sent a liquidating distribution to its remaining shareholders, in cash and partly consisting of portfolio securities, equal to the shareholders' proportionate interest in the net assets of the Fund. As of such date, the Fund was dissolved in accordance with the Fund's Declaration of Trust. 21 Trustees and Officers 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 June 30, 2006.

Mellon Institutional Funds Investment Trust Standish Mellon Opportunistic High Yield 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 (January 1, 2006 to June 30, 2006). 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 expenses 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 January 1, 2006 January 1, 2006 June 30, 2006 to June 30, 2006 - ---------------------------------------------------------------------------------------------------------------------------- Actual $1,000.00 $1,013.70 $0.50 Hypothetical (5% return per year before expenses) $1,000.00 $1,024.30 $0.50 - ----------- + Expenses are equal to the Fund's annualized expense ratio of 0.10%, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 1 Mellon Institutional Funds Investment Trust Standish Mellon Opportunistic High Yield Fund Portfolio Information as of June 30, 2006 (Unaudited) - -------------------------------------------------------------------------------- Percentage of Top Ten Holdings* Rate Maturity Investments - ----------------------------------------------------------------------------------------------------------------- Chevy Chase Bank FSB 6.875 12/1/2013 2.4% AES Corp. 144A 8.750 5/15/2013 1.7 Freescale Semiconductor, Inc. 6.875 7/15/2011 1.7 Nevada Power Co. 6.500 4/15/2012 1.7 Owens-Illinois, Inc. 7.500 5/15/2010 1.2 Transcontinental Gas Pipe Line Corp. 8.875 7/15/2012 1.1 Speedway Motorsports, Inc. 6.750 6/1/2013 1.0 Invista 144A 9.250 5/1/2012 1.0 Qwest Communications International 7.500 2/15/2014 1.0 Kaupthing Bank 144A 7.125 5/19/2016 1.0 ----- 13.8% * Excluding short-term investments and investment of cash collateral.

Standish Mellon Opportunistic High Yield Fund (the "Fund") is a separate non-diversified investment series of the Trust. The objective of the Fund is to maximize total return, consistent with preserving principal, primarily through the generation of current income and, to a lesser extent, capital appreciation by investing, under normal circumstances, at least 80% of net assets in below investment grade fixed income securities. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities 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 quoted bid price. 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. 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. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. The Fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. Net realized gains and losses on foreign currency transactions represent gains and losses on disposition of foreign currencies and forward foreign currency exchange contracts, currency gains and losses realized between the trade and settlement dates on securities transactions, and the difference between the amount of investment income and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent amounts actually received or paid. C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. 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, amortization and/or accretion of premiums and discounts on certain securities and capital loss carryforwards. 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. 13 Mellon Institutional Funds Investment Trust Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- Standish Mellon Opportunistic High Yield Fund D. Foreign currency transactions The Fund maintains its 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. 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. 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. 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 Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, or its affiliates. (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 payable monthly at the annual rate of 0.40% of the Fund's average daily net assets. Standish Mellon voluntarily agreed to limit total Fund operating expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.10% of the Fund's average daily net assets for the six months ended June 30, 2006. Pursuant to this agreement, for the six months ended June 30, 2006, Standish Mellon voluntarily waived its investment advisory fee in the amount of $36,410 and reimbursed the Fund for $61,383 of its operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Fund 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 $3,238 during the six months ended June 30, 2006. The Fund 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 fund accounting services for the Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement the Fund was charged $24,904 during the six months ended June 30, 2006. The Fund 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 collected $1,329 for the six months ended June 30, 2006. See Note 7 for further details. 14 Mellon Institutional Funds Investment Trust Standish Mellon Opportunistic High Yield Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Fund 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 during the six months ended June 30, 2006. The Trust reimburses Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2006, the Fund was charged $1,933. 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 Trust pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee and a per meeting fee as well as reimbursement for travel and out of pocket expenses. In addition, the Trust pays the legal fees for the independent counsel of the Trustees. 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 June 30, 2006 were as follows: Purchases Sales ----------- ----------- Investments (non-U.S. Government Securities) $ 2,720,485 $ 5,160,932 =========== =========== (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 Year Ended Year Ended June 30, 2006 December 31, 2005 Shares sold -- 439,323 Shares issued to shareholders reinvestment of distributions declared 25,842 58,759 Shares redeemed (189,788) (339,279) --------- --------- Net increase (decrease) (163,946) 158,803 ========= ========= At June 30, 2006, four shareholders of record held approximately 74% 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 June 30, 2006, the Fund did not collect any redemption fees 15 Mellon Institutional Funds Investment Trust Standish Mellon Opportunistic High Yield Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (5) Federal Taxes: The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2006, as computed on a federal income tax basis, were as follows: Aggregate cost $18,095,180 =========== Gross unrealized appreciation 267,017 Gross unrealized depreciation (424,210) =========== Net unrealized appreciation (depreciation) $(157,193) =========== (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 instruments with off-balance sheet risk: Options Call and put options give the holder the right to purchase or sell a security or currency or enter into a swap arrangement on a future date at a specified price. The Fund may use options to seek to hedge against risks of market exposure and changes in security prices and foreign currencies, as well as to seek to enhance returns. Writing puts and buying calls tend to increase the Fund's exposure to the underlying instrument. Buying puts and writing calls tend to decrease the Fund's exposure to the underlying instrument, or hedge other Fund investments. Options, both held and written by the Fund, are reflected in the accompanying Statement of Assets and Liabilities at market value. The underlying face amount at value of any open purchased option is shown in the Schedule of Investments. This amount reflects each contract's exposure to the underlying instrument at year end. Losses may arise from changes in the value of the underlying instruments if there is an illiquid secondary market for the contract or if the counterparty does not perform under the contract's terms. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. Realized gains and losses on purchased options are included in realized gains and losses on investment securities, except purchased options on foreign currency which are included in realized gains and losses on foreign currency transactions. If a put option written by the Fund is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund, as a writer of an option, has no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option. Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by the dealers. The Fund did not enter into any options transactions during the six months ended June 30, 2006. Forward currency exchange contracts The Fund may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any gains or losses are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Fund primarily to protect the value of the Fund's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2006, the Fund held currency exchange contracts. See the Schedule of Investments for further details. Futures contracts The Fund may enter into financial futures contracts for the delayed sale or delivery of securities or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Fund deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the Fund each day, depending on the daily fluctuations in the value of the underlying 16 Mellon Institutional Funds Investment Trust Standish Mellon Opportunistic High Yield Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- security, and are recorded for financial statement purposes as unrealized gains or losses by the Fund. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Fund's exposure to the underlying instrument, while selling futures tends to decrease the Fund's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may arise if there is an illiquid secondary market or if the 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 June 30, 2006, the Fund did not hold any futures contracts. See the Schedule of Investments for further details. Swap agreements The Fund may enter into swap agreements. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The Fund may enter into interest rate, credit default and total return swap agreements to manage its exposure to interest rates and credit risk. Interest rate swap agreements involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. In a credit default swap, one party makes a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party on its obligation. The Fund may use credit default swaps to provide a measure of protection against defaults of issuers (i.e., to reduce risk where the Fund owns or has exposure to the corporate or sovereign issuer) or to take an active long or short position with respect to the likelihood of a particular corporate or sovereign issuer's default. Total return swap agreements involve commitments to pay interest in exchange for a market-linked return, both based on notional amounts. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, a fund will receive a payment from or make a payment to the counterparty. In connection with these agreements, cash or securities may be set aside as collateral in accordance with the terms of the swap agreement. Swaps are marked to market daily based upon quotations, which may be furnished by a pricing service or dealers in such securities, and the change in value, if any, is recorded as unrealized gain or loss in the Statement of Operations. These financial instruments are not actively traded on financial markets. The values assigned to these instruments are based upon the best available information and because of the uncertainty of the valuation, these values may differ significantly from the values that would have been realized had a ready market for these instruments existed, and differences could be material. Payments received or made at the beginning of the measurement period are reflected as such on the Statement of Assets and Liabilities. Payments received or made from credit default swaps at the end of the measurement period are recorded as realized gain or loss in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gain and loss. Entering into these agreements involves, to varying degrees, elements of credit, market, and documentation risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates. At June 30, 2006, the Fund held open swap agreements. 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 loaned securities during the six months ended June 30, 2006 and earned interest on the invested collateral of $36,128, of which $32,981 was rebated to borrowers or paid in fees. At June 30, 2006, the Fund had securities valued at $1,077,243 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. 17 Mellon Institutional Funds Investment Trust Standish Mellon Opportunistic High Yield Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (8) Delayed Delivery Transactions: The Fund may purchase securities on a when-issued, delayed delivery or forward commitment basis. Payment and delivery may take place a month or more after the date of the transactions. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Income on the securities will not be earned until settlement date. The Fund instructs its custodian to segregate securities having value at least equal to the amount of the purchase commitment. The Fund may enter into to be announced (TBA) purchase commitments to purchase securities for a fixed unit price at a future date beyond customary settlement time. Although the unit price has been established, the principal value has not been finalized. However, the amount of the commitments will not fluctuate more than 0.01% from the principal amount. The Fund holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the Fund may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities, according to the procedures described under "Investment security valuations" above. The Portfolio may enter into TBA sale commitments to hedge its portfolio positions. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, an offsetting TBA purchase commitment deliverable is held as "cover" for the transaction. For six months ended June 30, 2006, the Fund did not enter into any delayed delivery transactions. (9) 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%.
