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, 2007 to June 30, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period(t) Account Value Account Value January 1, 2007 January 1, 2007 June 30, 2007 to June 30, 2007 --------------- ------------- ---------------- Actual $ 1,000.00 $ 1,008.60 $ 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. 3 Mellon Institutional Funds Investment Trust Standish Mellon Fixed Income Fund Portfolio Information as of June 30, 2007 (Unaudited) - -------------------------------------------------------------------------------- The Standish Mellon Fixed Income Fund invests all of its investable assets in an interest of the Standish Mellon Fixed Income Portfolio (See Note 1 of the Fund's Notes to Financial Statements).

Standish Mellon Fixed Income Fund (the "Fund") is a separate diversified investment series of the Trust. The objective of the Fund is primarily 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. The Fund invests all of its investable assets in an interest of Standish Mellon Fixed Income Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust and has the same investment objective as the Fund. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in 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, 2007). The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. The Fund records its 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 The Fund's investment in the Portfolio is recorded on settlement date. The Portfolio's securities transactions are recorded as of the trade date as discussed in Note 1B of the Portfolio's Notes to Financial Statements, which are included elsewhere in the report. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. All realized and unrealized gains and losses of the Fund represent pro rata shares of gains and losses of the Portfolio. C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. The Fund's distributions from capital gains, if any, after reduction of capital losses are declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These differences which may result in reclassifications, are primarily due to wash sales, foreign currency gains and losses, post-October losses, capital loss carryovers, and the timing of recognition of realized and unrealized gains and losses on futures contracts. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income(loss), accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (loss) and accumulated net realized gain (loss) on investments may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. 9 Mellon Institutional Funds Investment Trust Standish Mellon 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. F. New accounting requirements In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (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 The Bank of New York Mellon Corporation ("BNY Mellon"), 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 0.50% of the Fund's average daily net assets. Pursuant to this agreement, for the six months ended June 30, 2007, Standish Mellon voluntarily reimbursed the Fund $197 of its operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as, out-of-pocket expenses. Pursuant to this agreement the Fund was charged $11,128, for the six months ended June 30, 2007. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $2,218, which is included in miscellaneous expenses in the statement of operations for the six months ended June 30, 2007. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2007, the Fund was charged $2,119, which is included in miscellaneous expenses on the statement of operations. No other director, officer or employee of Standish Mellon or its affiliates receives any compensation from the Trust or the Fund for serving as an officer or Trustee of the Trust. The Fund pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee. 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, 2007, the Fund was charged $107,064 for fees payable to BNY Mellon Private Wealth Management. Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish, replaced Mellon Funds Distributor, L.P. as the Fund's principal distributor. 10 Mellon Institutional Funds Investment Trust Standish Mellon Fixed Income Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended June 30, 2007, aggregated $80,500,934 and $72,705,104, 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, 2007 December 31, 2006 ------------- ----------------- Shares sold 3,626,456 9,061,206 Shares issued to shareholders for reinvestment of distributions 453,105 788,837 Share redeemed (2,996,698) (4,504,759) ----------- ----------- Net increase (decrease) 1,082,863 5,345,284 =========== =========== At June 30, 2007, two shareholders of record, in the aggregate, held approximately 24% 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, 2007 and the year ended December 31, 2006, the Fund received redemption fees of $4,935 and $4,451, which is reflected in the cost of shares redeemed. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. In July 2006, FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures.

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, 2007 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, 2007 was 100%. The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last quoted bid price. Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Portfolio's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Portfolio's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. Exchange traded options and futures are valued at the settlement price determined by the relevant exchange. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers, including counterparties, or pricing services. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Portfolio acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity. Dividend income is recorded on the ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. 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. Dividends representing a return of capital are reflected as a reduction of cost. C. Income taxes The Portfolio is treated as a disregarded entity for U.S. federal income 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. 31 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio 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 Portfolio maintains its books and records in U.S. dollars. Investment security valuations, other assets, and liabilities initially expressed in foreign currencies are converted into U.S. dollars based upon current currency exchange rates. Purchases and sales of foreign investment securities and income and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. E. Foreign investment risk There are certain additional risks involved in investing in foreign securities that are not inherent in investments in domestic securities. These risks may involve adverse political and economic developments, including the possible imposition of capital controls or other foreign governmental laws or restrictions. In addition, the securities of some foreign companies and securities markets are less liquid and at times may be more volatile than securities of comparable U.S. companies and U.S. securities markets. The risks described above apply to an even greater extent to investments in emerging markets. The securities markets of emerging countries are generally smaller, less developed, less liquid, and more volatile than the securities markets of the U.S. and developed foreign markets. F. Commitments and contingencies In the normal course of business, the Portfolio may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Portfolio under these arrangements is unknown, as this would involve future claims that may be made against the Portfolio that have not yet occurred. However, based on experience, the Portfolio expects the risks of loss to be remote. G. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among 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 The Bank of New York Mellon Corporation ("BNY Mellon"), or its affiliates. I. New accounting requirements In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory 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 Trust has entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide custody, administration and fund accounting services for the 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 $125,953 during for the six months ended June 30, 2007. 32 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Portfolio Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Fund's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues, pursuant to this agreement, Mellon Bank earned $1,106 for the six months ended June 30, 2007. See Note 6 for further details. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's and Portfolio Trust's Chief Compliance Officer. No other director, officer or employee of 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, 2007 were as follows: Purchases Sales --------------- --------------- U.S. Government Securities $ 1,604,586,557 $ 1,590,298,570 --------------- --------------- Non-U.S. Government Securities $ 142,256,062 $ 74,117,112 --------------- --------------- (4) Federal Taxes The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $ 867,321,100 ============== Gross unrealized appreciation 2,794,336 Gross unrealized depreciation (6,436,420) -------------- Net unrealized appreciation (depreciation) ($ 3,642,084) ============== In July 2006, FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the implications on FIN 48 and determined that it will not have any impact on the financial statements. (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. 33 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. Realized gains and losses on purchased options are included in realized gains and losses on investment securities, except purchased options on foreign currency which are included in realized gains and losses on foreign currency transactions. If a put option written by the 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 including counterparties. For the six months ended June 30, 2007, the Portfolio entered into the following transactions: Notional Written Call Option Transactions Amount Premiums --------- -------- Outstanding, beginning of period $ - $ - Options written 206,000 37,972 Options expired (206,000) (37,972) --------- -------- Outstanding, end of period $ - $ - ========= ======== At June 30, 2007, 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 appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Portfolio primarily to protect the value of the Portfolio's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2007, 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 purchase or sale of securities, or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments, shown as variation margin, are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized appreciation/depreciation by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may also arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Appreciation and depreciation 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, 2007, the Portfolio held open financial futures contracts. See the Schedule of Investments for further details. 34 Mellon Institutional Funds Master Portfolio Standish Mellon 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, the 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. The Portfolio earns interest on cash set aside as collateral. 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 appreciation or depreciation 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 gains and losses in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gains and losses. 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, 2007, 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, 2007 and earned interest on the invested collateral of $1,478,251 of which, $1,453,656 was rebated to borrowers or paid in fees. At June 30, 2007, the Portfolio had securities valued at $72,209,837 on loan, of which $68,966,218 was collateralized with cash and $5,960,556 was collateralized with securities. 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. 35 Mellon Institutional Funds Master Portfolio Standish Mellon Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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, 2007, 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. The Fund/Portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the funds/portfolios. For the six months ended June 30, 2007, the expense allocated to the Portfolio was $556. The facility fee and interest expense is aggregated with miscellaneous expenses on the Statement of Operations. For the six months ended June 30, 2007, the Portfolio did not borrow from the credit line. 36 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their age, 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, 2007.

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, 2007 to June 30, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value January 1, 2007 January 1, 2007 June 30, 2007 to June 30, 2007 - --------------------------------------------------------------------------------------------------------------------------- Actual $1,000.00 $1,002.70 $3.23 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. 3 Mellon Institutional Funds Investment Trust Standish Mellon Global Fixed Income Fund Portfolio Information as of June 30, 2007 (Unaudited) - -------------------------------------------------------------------------------- The Standish Mellon Global Fixed Income Fund invests all of its investable assets in an interest of the Standish Mellon Global Fixed Income Portfolio (See Note 1 of the Fund's Notes to Financial Statements). The Portfolio is actively managed. Current holdings may be different than those presented below.

Standish Mellon Global Fixed Income Fund (the "Fund") is a separate non-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 invests all of its investable assets in an interest of Standish Mellon Global Fixed Income Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust and has the same investment objective as the Fund. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of 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 December 31, 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. Effective May 1, 2007, the Board approved Fund strategy changes to ease limits on investments in emerging markets and high yield investments and lower the minimum average credit quality of the Fund. Specifically, the changes: (i) increased the limitations on high yield exposure from 15% to 25% of Fund's total assets; (ii) changed the description of the Fund's average credit quality from a "target in the range of A to AA/Aa" to "a minimum of A-/A3" and (iii) increased the general limitation on investing in issuers located in emerging markets from 10% to 25% of the total assets of the Fund. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. The Fund records its investments in the Portfolio at value. The Portfolio values its securities at value as discussed in Note 1A of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. B. Securities transactions and income The Fund's investments in the Portfolio are recorded on settlement date. The Portfolio's securities transactions are recorded as of the trade date as discussed in Note 1B of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. All realized and unrealized gains and losses of the Fund represent pro rata shares of gains and losses of the Portfolio. C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. The Fund's distributions from capital gains, if any, after reduction of capital losses are declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for losses deferred due to wash sales, foreign currency gains and losses, post-October losses, capital loss carryovers, and the timing of recognition of realized and unrealized gains and losses on futures contracts. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income (loss), accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (loss) and accumulated net realized gain (loss) on investments may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. 9 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. F. New accounting requirements In September 2006, the Financial Standards Accounting Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The 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 The Bank of New York Mellon Corporation ("BNY Mellon"), 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, 2007, Standish Mellon voluntarily reimbursed the Fund for $37,739 of its operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as, out-of-pocket expenses. Pursuant to this agreement the Fund was charged $2,719, for the six months ended June 30, 2007. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2007, the Fund was charged $2,089. No other director, officer or employee of Standish Mellon or its affiliates receives any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust. The Fund pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $1,160 for the six months ended June 30, 2007. The Fund pays administrative service fees. These fees are paid to affiliated or unaffiliated retirement plans, omnibus accounts and platform administrators and other entities ("Plan Administrators") that provide record keeping and/or other administrative support services to accounts, retirement plans and their participants. As compensation for such services, the Fund may pay each Plan Administrator an administrative service fee in an amount of up to 0.15% (on an annualized basis) of the Fund's average daily net assets attributable to Fund shares that are held in accounts serviced by such Plan Administrator. The Fund's adviser or its affiliates may pay additional compensation from their own resources to Plan Administrators and other entities for administrative services, as well as in consideration of marketing or other distribution-related services. These payments may provide an incentive for these entities to actively promote the Fund or cooperate with the distributor's promotional efforts. For the six months ended June 30, 2007, the Fund was charged $50 for fees payable to BNY Mellon Private Wealth Management. Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, replaced Mellon Funds Distributor, L.P. as the Fund's principal distributor. 10 Mellon Institutional Funds Investment Trust Standish Mellon Global Fixed Income Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended June 30, 2007, aggregated $371,505 and $10,748,444, 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, 2007 December 31, 2006 ----------------- ----------------- Shares sold 25,474 112,735 Shares issued to shareholders for reinvestment of distributions 20,180 74,640 Shares redeemed (202,612) (1,786,209) ---------- ------------- Net increase (decrease) (156,958) (1,598,834) ========== ============= At June 30, 2007, one shareholder of record held approximately 83% of the total outstanding shares of the Fund. Investment activities of this shareholder could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended June 30, 2007, the Fund did not assess any redemption fees. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. In July 2006, FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the implications of FIN 48 and determined that it will not have any impact on the financial statements. See the corresponding master portfolio for tax basis unrealized appreciation (depreciation) information. 11 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Schedule of Investments -- June 30, 2007 (Unaudited) - -------------------------------------------------------------------------------- Par Value Security Description Rate Maturity Value (Note 1A) - ---------------------------------------------------------------------------------------------------------------------------------- UNAFFILIATED INVESTMENTS--119.5% BONDS AND NOTES--97.0% Asset Backed--5.0% Americredit Prime Automobile Receivables 5.270% 10/8/2011 USD 385,000 $ 383,884 Capital Auto Receivables Asset Trust 2006-2 B 5.070 12/15/2011 160,000 157,881 Chase Issuance Trust 2007-A1 A1 (a) 5.340 3/15/2013 280,000 279,997 Credit Suisse Mortgage Capital Certificate 2007-1 1A6A (a) 5.863 2/25/2037 260,000 254,184 CSAB Mortgage Backed Trust 2006-3 A1B2 (a) 5.415 11/25/2036 179,427 179,456 Home Equity Mortgage Trust 2006-5 A1 5.500 1/25/2037 163,875 163,709 JP Morgan Alternative Loan Trust 2006-S4 A6 5.710 12/25/2036 225,000 219,533 USAA Auto Owner Trust 5.430 10/17/2011 255,000 255,000 ----------- Total Asset Backed (Cost $1,903,822) 1,893,644 ----------- Collateralized Mortgage Obligations--9.0% Government National Mortgage Association 2004-23 B 2.946 3/16/2019 275,105 264,484 Government National Mortgage Association 2005-76 A 3.963 5/16/2030 274,947 266,939 Government National Mortgage Association 2005-79 A 3.998 10/16/2033 269,635 262,546 Government National Mortgage Association 2006-5 A 4.241 7/16/2029 265,695 258,921 Government National Mortgage Association 2006-9 A 4.201 8/16/2026 645,059 628,095 Government National Mortgage Association 2006-15 A 3.727 3/16/2027 338,578 327,608 Government National Mortgage Association 2006-19 A 3.387 6/16/2030 230,572 221,804 Government National Mortgage Association 2006-39 A 3.772 6/16/2025 335,316 323,617 Government National Mortgage Association 2006-67 A 3.947 11/16/2030 484,916 469,047 Government National Mortgage Association 2006-68 A 3.888 7/16/2026 236,641 228,702 Government National Mortgage Association 2007-34A 4.272 11/16/2026 175,000 170,352 ----------- Total Collateralized Mortgage Obligations (Cost $3,421,248) 3,422,115 ----------- Corporate--19.1% Banking--5.8% Bank of America Capital Trust XIII (a) 5.760 3/15/2049 140,000 137,384 Chevy Chase Bank FSB 6.875 12/1/2013 295,000 293,525 GMAC LLC (a) 6.610 5/15/2009 120,000 119,995 ICICI Bank Ltd. 144A (a)(g) 6.375 4/30/2022 150,000 142,537 Shinsei Finance Cayman Ltd 144A (a) 6.418 1/29/2049 200,000 194,461 SMFG Preferred Capital 144A (a) 6.078 1/29/2049 200,000 192,402 Societe Generale 144A (a) 5.922 4/29/2049 125,000 121,029 Sovereign Bancorp (a) 5.590 3/23/2010 215,000 215,063 Suntrust Preferred Capital I (a) 5.853 12/15/2036 40,000 39,759 USB Capital IX (a) 6.189 4/15/2049 300,000 302,215 Washington Mutual Bank (a) 5.446 5/1/2009 245,000 245,160 Washington Mutual, Inc 4.625 4/1/2014 200,000 183,823 ----------- 2,187,353 ----------- Broadcasting--0.8 % Time Warner, Inc.

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. Effective May 1, 2007, the Board approved Portfolio strategy changes to ease limits on investments in emerging markets and high yield investments and lower the minimum average credit quality of the Portfolio. Specifically, the changes: (i) increased the limitations on high yield exposure from 15% to 25% of Portfolio's total assets; (ii) changed the description of the Portfolio's average credit quality from a "target in the range of A to AA/Aa" to "a minimum of A-/A3" and (iii) increased the general limitation on investing in issuers located in emerging markets from 10% to 25% of the total assets of the Portfolio. At June 30, 2007 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, 2007 was 100%. The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last quoted bid price. Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Portfolio's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Portfolio's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. Exchange traded options and futures are valued at the settlement price determined by the relevant exchange. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers, including counterparties, or pricing services. Because foreign markets may be open at different times than the New York Stock Exchange ("NYSE"), the value of the Portfolio's shares may change on days when shareholders are not able to buy or sell them. Many securities markets and exchanges outside the U.S. close prior to the close of the NYSE and therefore the closing prices for securities in such markets or on such exchanges may not fully reflect the events that occur after such close but before the close of the NYSE. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Portfolio acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity. Dividend income is recorded on the ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. 24 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Portfolio does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. Net realized gains and losses on foreign currency transactions represent gains and losses on disposition of foreign currencies and forward foreign currency exchange contracts, currency gains and losses realized between the trade and settlement dates on securities transactions, and the difference between the amount of investment income and foreign withholding taxes recorded on the Portfolio's books and the U.S. dollar equivalent amounts actually received or paid. C. Income taxes The Portfolio is treated as a disregarded entity for U.S. federal income 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. D. Foreign currency transactions The Portfolio maintains its books and records in U.S. dollars. Investment security valuations, other assets, and liabilities initially expressed in foreign currencies are converted into U.S. dollars based upon current currency exchange rates. Purchases and sales of foreign investment securities and income and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. E. Foreign investment risk There are certain additional risks involved in investing in foreign securities that are not inherent in investments in domestic securities. These risks may involve adverse political and economic developments, including the possible imposition of capital controls or other foreign governmental laws or restrictions. In addition, the securities of some foreign companies and securities markets are less liquid and at times may be more volatile than securities of comparable U.S. companies and U.S. securities markets. The risks described above apply to an even greater extent to investments in emerging markets. The securities markets of emerging countries are generally smaller, less developed, less liquid, and more volatile than the securities markets of the U.S. and developed foreign markets. F. Commitments and contingencies In the normal course of business, the Portfolio may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Portfolio under these arrangements is unknown, as this would involve future claims that may be made against the Portfolio that have not yet occurred. However, based on experience, the Portfolio expects the risks of loss to be remote. G. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among 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 The Bank of New York Mellon Corporation ("BNY Mellon"), or its affiliates. 25 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- I. New accounting requirements In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory, 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 annual 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, 2007, Standish Mellon voluntarily waived a portion of its investment advisory fee in the amount of $19,781. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Portfolio Trust has entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide custody, administration and fund accounting services for the 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 $46,410 during for the six months ended June 30, 2007. The Portfolio Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Portfolio's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $634 for the six months ended June 30, 2007. See Note 6 for further details. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's and Portfolio Trust's Chief Compliance Officer. No other director, officer or employee of 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, 2007 were as follows: Purchases Sales ----------- ----------- U.S. Government Securities $41,160,381 $40,678,538 ----------- ----------- Non-U.S. Government Securities $ 6,147,786 $12,529,923 ----------- ----------- (4) Federal Taxes: In July 2006, FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the implications of FIN 48 and determined that it will not have any impact on the financial statements. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $ 45,850,402 ============ Gross unrealized appreciation 468,317 Gross unrealized depreciation (424,130) ------------ Net unrealized appreciation (depreciation) $ 44,187 ============ 26 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (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, including counterparties. For the six months ended June 30, 2007, the Portfolio entered into the following transactions: Number of Written Put Option Transactions Contracts Premiums ---------- --------- Outstanding, beginning of period -- $ -- Options written 18 3,318 ---------- --------- Outstanding, end of period 18 $ 3,318 ========== ========= Notional Written Call Option Transactions Amount Premiums ---------- --------- Outstanding, beginning of period $ -- $ -- Options written 124,400 13,062 ---------- --------- Outstanding, end of period $ 124,400 $ 13,062 ========== ========= At June 30, 2007, 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 appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Portfolio primarily to protect the value of the Portfolio's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2007, the Portfolio held forward currency exchange contracts. See the Schedule of Investments for further details. 27 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- Futures contracts The Portfolio may enter into financial futures contracts for the purchase or sale of securities, or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments, shown as variation margin, are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized appreciation/depreciation by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may also arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Appreciation and depreciation 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, 2007, the Portfolio held open financial futures contracts. See the Schedule of Investments for further details. 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, the 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. The Portfolio earns interest on cash set aside as collateral. 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 appreciation or depreciation 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 gains and losses in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gains and losses. 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, 2007, 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. 28 Mellon Institutional Funds Master Portfolio Standish Mellon Global Fixed Income Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- The Portfolio loaned securities during the six months ended June 30, 2007 and earned interest on the invested collateral of $70,564 of which, $69,092 was rebated to borrowers or paid in fees. At June 30, 2007, the Portfolio had securities valued at $869,553 on loan of which, $761,400 was collateralized with cash and $171,600 was collateralized with securities. 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. At June 30, 2007, 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. The Fund/Portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the funds/portfolios. For the six months ended June 30, 2007, the expense allocated to the Portfolio was $1,079. The facility fee and interest expense is aggregated with miscellaneous expenses on the Statement of Operations. For the six months ended June 30, 2007, the Fund/Portfolio had average borrowings outstanding of $2,782,400 for a total of four days and incurred $1,178 of interest expense. At June 30, 2007 the Fund/Portfolio had no borrowings outstanding. 29 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their age, 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, 2007.

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, 2007 to June 30, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value January 1, 2007 January 1, 2007 June 30, 2007 to June 30, 2007 - --------------------------------------------------------------------------------------------------- Actual $1,000.00 $1,024.30 $3.01 Hypothetical (5% return per year before expenses) $1,000.00 $1,021.82 $3.01 - -------------------- + Expenses are equal to the Fund's annualized expense ratio of 0.60%, 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. 3 Mellon Institutional Funds Investment Trust Standish Mellon High Yield Bond Fund Portfolio Information as of June 30, 2007 (Unaudited) - -------------------------------------------------------------------------------- The Standish Mellon High Yield Bond Fund invests all of its investable assets in an interest of the Standish Mellon High Yield Bond Portfolio (See Note 1 of the Fund's Notes to Financial Statements).

Standish Mellon High Yield Bond Fund (the "Fund") is a separate diversified investment series of the Trust. The objective of the Fund is to maximize total return, consisting of a high level of income. The Fund invests all of its investable assets in an interest in Standish Mellon High Yield Bond Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust and has the same investment objective as the Fund. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in 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, 2007). The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. The Fund records its 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 The Fund's investments in the Portfolio is recorded on settlement date. The Portfolio's securities transactions are recorded as of the trade date as discussed in Note 1B of the Portfolio's Notes to Financial Statements, which are included elsewhere in the report. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. All realized and unrealized gains and losses of the Fund represent pro rata shares of gains and losses of the Portfolio. C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. The Fund's distributions from capital gains, if any, after reduction of capital losses are declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These differences which may result in reclassifications, are primarily due to differing treatments for losses deferred due to wash sales, foreign currency gains and losses, post-October losses, capital loss carryovers, and the timing of recognition of realized and unrealized gains and losses on futures contracts. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income(loss), accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (loss) and accumulated net realized gain (loss) on investments may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. D. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust and/or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. 9 Mellon Institutional Funds Investment Trust 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. F. New accounting requirements In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The Fund does not directly pay any investment advisory fees, but indirectly bears its pro rata share of the compensation paid by the Portfolio to Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of The Bank of New York Mellon Corporation ("BNY Mellon"), 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's expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.50% of the Fund's average daily net assets. Pursuant to this agreement, for the six months ended June 30, 2007, Standish Mellon voluntarily reimbursed the Fund for $37,939 of its operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as, out-of-pocket expenses. Pursuant to this agreement the Fund was charged $2,892, for the six months ended June 30, 2007. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $1,256, which is included in miscellaneous expenses in the statement of operations for the six months ended June 30, 2007. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2007, the Fund was charged $2,090. No other director, officer or employee of Standish Mellon or its affiliates receives any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust. The Fund pays each Trustee who is not a director, officer or employee of 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, 2007, the Fund was charged $436 for fees payable to BNY Mellon Private Wealth Management. Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish, replaced Mellon Funds Distributor, L.P. as the Fund's principal distributor. (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended June 30, 2007, aggregated $5,311,158 and $16,623,108, 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. 10 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, 2007 December 31, 2006 ---------------- ----------------- Shares sold 288,799 1,034,865 Shares issued to shareholders for reinvestment of distributions 36,644 64,914 Shares redeemed (984,356) (525,494) --------- --------- Net increase (decrease) (658,913) 574,285 ========= ========= At June 30, 2007, three shareholders of record, in the aggregate, held approximately 73% 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, 2007, the Fund received $201 in redemption fees and is reflected in the cost of shares redeemed. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. In July 2006, the FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the implications of FIN 48 and determined that it will not have any impact on the financial statements. See the corresponding master portfolio for tax basis unrealized appreciation (depreciation) information. 11 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond Portfolio Schedule of Investments -- June 30, 2007 (Unaudited) - -------------------------------------------------------------------------------- Par Value Security Description Rate Maturity Value (Note 1A) - ----------------------------------------------------------------------------------------------------------------------------------- UNAFFILIATED INVESTMENTS--115.2% BONDS AND NOTES--97.5% Convertible Corporate Bonds--0.4% Alliant Techsystems, Inc. 144A 2.750% 2/15/2024 USD 25,000 $ 32,687 L-3 Communications Corp. 3.000 8/1/2035 30,000 33,825 --------- Total Convertible Corporate Bonds (Cost $56,124) 66,512 --------- Asset Backed--0.1% Countrywide Asset-Backed Certificates 2007-4 M7 (Cost $18,766) 7.200 9/25/2037 20,000 18,180 --------- Corporate--87.2% Banking--1.8% BF Saul REIT 7.500 3/1/2014 55,000 55,206 Chevy Chase Bank FSB 6.875 12/1/2013 245,000 243,775 --------- 298,981 --------- Basic Industry--0.5% Cinemark Inc 0.000 3/15/2014 65,000 59,150 Smurfit-Stone Container Emterprises 8.000 3/15/2017 25,000 24,250 --------- 83,400 --------- Communications--0.7% Sinclair Broadcast Group, Inc (2% beginning 1/15/2011)(a) 4.875 7/15/2018 45,000 43,706 NXP Funding LLC 7.875 10/15/2014 75,000 73,875 --------- 117,581 --------- Financial--6.1% Arch Western Finance 6.750 7/1/2013 90,000 86,400 E*Trade Financial Corp. 8.000 6/15/2011 20,000 20,500 Ford Motor Credit Co.

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, 2007 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, 2007 was 100%. The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last quoted bid price. Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Portfolio's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Portfolio's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. Exchange traded options and futures are valued at the settlement price determined by the relevant exchange. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers, including counterparties, or pricing services. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Portfolio acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity when required for federal income tax purposes. Dividend income is recorded on the ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. 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. 23 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- C. Income taxes The Portfolio is treated as a disregarded entity for U.S. federal income 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. D. Foreign currency transactions The Portfolio maintains its books and records in U.S. dollars. Investment security valuations, other assets, and liabilities initially expressed in foreign currencies are converted into U.S. dollars based upon current currency exchange rates. Purchases and sales of foreign investment securities and income and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. E. Foreign investment risk There are certain additional risks involved in investing in foreign securities that are not inherent in investments in domestic securities. These risks may involve adverse political and economic developments, including the possible imposition of capital controls or other foreign governmental laws or restrictions. In addition, the securities of some foreign companies and securities markets are less liquid and at times may be more volatile than securities of comparable U.S. companies and U.S. securities markets. The risks described above apply to an even greater extent to investments in emerging markets. The securities markets of emerging countries are generally smaller, less developed, less liquid, and more volatile than the securities markets of the U.S. and developed foreign markets. F. Commitments and contingencies In the normal course of business, the Portfolio may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Portfolio under these arrangements is unknown, as this would involve future claims that may be made against the Portfolio that have not yet occurred. However, based on experience, the Portfolio expects the risks of loss to be remote. G. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among the funds of the Trust or the portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. H. Affiliated issuers Affiliated issuers are investment companies advised by Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of The Bank of New York Mellon Corporation ("BNY Mellon"), or its affiliates. I. New accounting requirements In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. 24 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (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 Fund's total annual operating expenses of the Fund and its pro rata share of the Portfolio's expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.50% of the Fund's average daily net assets. Pursuant to this agreement, for the six months ended June 30, 2007, Standish Mellon voluntarily waived a portion of its investment advisory fee in the amount of $48,260. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Portfolio Trust has entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide custody, administration and fund accounting services for the 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 $32,698 during for the six months ended June 30, 2007. The Portfolio Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Portfolio's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $899 for the six months ended June 30, 2007. See Note 6 for further details. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's and Portfolio Trust's Chief Compliance Officer. No other director, officer or employee of 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, 2007 were as follows: Purchases Sales ---------- ----------- U.S. Government Securities $ 371,950 $ 264,287 ---------- ----------- Non-U.S. Government Securities $4,648,535 $14,953,376 ---------- ----------- (4) Federal Taxes: In July 2006, the FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the implications of FIN 48 and determined that it will not have any impact on the financial statements. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $18,769,042 =========== Gross unrealized appreciation 315,311 Gross unrealized depreciation (218,217) ----------- Net unrealized appreciation (depreciation) $ 97,094 =========== 25 Mellon Institutional Funds Master Portfolio Standish Mellon High Yield Bond Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (5) Financial Instruments: In general, the following instruments are used for hedging purposes as described below. However, these instruments may also be used to seek to enhance potential gain in circumstances where hedging is not involved. The Portfolio may trade the following financial instruments with off-balance sheet risk: Forward currency exchange contracts The Portfolio may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward currency exchange contracts are used by the Portfolio primarily to protect the value of the Portfolio's foreign securities from adverse currency movements. Unrealized appreciation and depreciation of forward currency exchange contracts is included in the Statement of Assets and Liabilities. At June 30, 2007, the Portfolio held forward currency exchange contracts. See the Schedule of Investments for further details. 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, the 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. The Portfolio earns interest on cash set aside as collateral. 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 appreciation or depreciation 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 appreciation/depreciation in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized appreciation and depreciation. 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, 2007, the Portfolio held open swap agreements. See the Schedule of Investments for further details. 26 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 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, 2007 and earned interest on the invested collateral of $62,846 of which, $60,757 was rebated to borrowers or paid in fees. At June 30, 2007, the Portfolio had securities valued at $2,389,575 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. (7) Line of Credit: The Portfolio, and other subtrusts in the Portfolio Trust and funds in the Trust are parties to a committed line of credit facility, which enables each portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is charged to each participating portfolio/fund based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating portfolios/funds at the end of each quarter. The Fund/Portfolio and funds also pay an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating funds/portfolios. For the six months ended June 30, 2007, the expense allocated to the Portfolio was $1,872. The facility fee and interest expense is aggregated with miscellaneous expenses on the Statement of Operations. For the six months ended June 30, 2007, the Portfolio had average borrowings outstanding of $989,750 for a total of twenty days and incurred $1,429 of interest expense. At June 30, 2007 the Portfolio had borrowings outstanding. (8) Subsequent Event: On June 22, 2007, the Board of Trustees of the Trust considered and approved a proposal to liquidate and dissolve the Fund. If the shareholders of record of the Fund approve these actions at a meeting anticipated to be held in late September 2007, the Fund will be liquidated and dissolved as soon as practicable thereafter. It is currently expected that the liquidation and dissolution of the Fund would be effective on or before the close of business on October 26, 2007. 27 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their age, 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, 2007.

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, 2007 to June 30, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period(+) Account Value Account Value January 1, 2007 January 1, 2007 June 30, 2007 to June 30, 2007 - -------------------------------------------------------------------------------- Actual $1,000.00 $ 998.50 $3.37 Hypothetical (5% return per year before expenses) $1,000.00 $1,021.42 $3.41 - -------- + Expenses are equal to the Fund's annualized expense ratio of 0.68%, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 3 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund Portfolio Information as of June 30, 2007 (Unaudited) - -------------------------------------------------------------------------------- Summary of Combined Ratings - ------------------------------------- Percentage of Quality Breakdown Investments - ------------------------------------- AAA and higher 74.2% AA 7.1 A 7.4 BBB 5.8 BB 2.5 B 3.0 ----- 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. Effective May 1, 2007, the Board approved Fund strategy changes to ease limits on investments in emerging markets and high yield investments and lower the minimum average credit quality of the Fund. Specifically, th e changes: (i) increased the limitations on high yield exposure from 15% to 25% of Fund's total assets; (ii) changed the description of the Fund's average credit quality from a "target in the range of A to AA/Aa" to "a minimum of A-/A3" and (iii) increased the general limitation on investing in issuers located in emerging markets from 10% to 25% of the total assets of the Fund. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last quoted bid price. Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Fund's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. Exchange traded options and futures are valued at the settlement price determined by the relevant exchange. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers, including counterparties, or pricing services. Because foreign markets may be open at different times than the NYSE, the value of the Fund's shares may change on days when shareholders are not able to buy or sell them. Many securities markets and exchanges outside the U.S. close prior to the close of the NYSE and therefore the closing prices for securities in such markets or on such exchanges may not fully reflect the events that occur after such close but before the close of the NYSE. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Fund acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity when required for federal income tax purposes. Dividend income is recorded on the ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. 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 appreciation or depreciation from investments. Net realized appreciation (depreciation) 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. 16 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- C. Distributions to Shareholders Distributions to shareholders are recorded on the ex-dividend date. The Fund's distributions from capital gains, if any, after reduction of capital losses will be declared and distributed at least annually. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for foreign currency transactions, losses deferred due to wash sales, post-October losses, amortization and/or accretion of premiums and discounts on certain securities, amortization of swap premium and the timing of recognition of realized and unrealized appreciation and depreciation on futures contracts. Permanent book and tax basis diff erences relating to shareholder distributions will result in reclassifications among undistributed net investment income (loss), accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (loss) and accumulated net realized gain (loss) on investments may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. Section 988 of the Internal Revenue Code provides that gains or losses on certain transactions attributable to fluctuations in foreign currency exchange rates must be treated as ordinary income or loss. For financial statement purposes, such amounts are included in net realized gains or losses. D. Foreign currency transactions The Fund maintains its books and records in U.S. dollars. Investment security valuations, other assets, and liabilities initially expressed in foreign currencies are converted into U.S. dollars based upon current currency exchange rates. Purchases and sales of foreign investment securities and income and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. E. Foreign investment risk There are certain additional risks involved in investing in foreign securities that are not inherent in investments in domestic securities. These risks may involve adverse political and economic developments, including the possible imposition of capital controls or other foreign governmental laws or restrictions. In addition, the securities of some foreign companies and securities markets are less liquid and at times may be more volatile than securities of comparable U.S. companies and U.S. securities markets. The risks described above apply to an even greater extent to investments in emerging markets. The securities markets of emerging countries are generally smaller, less developed, less liquid, and more volatile than the securities markets of the U.S. and developed foreign markets. F. Commitments and contingencies In the normal course of business, the 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. G. Expenses The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated among funds of the Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds. H. Affiliated issuers Affiliated issuers are investment companies advised by Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of The Bank of New York Mellon Corporation ("BNY Mellon"), or its affiliates. 17 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- I. New Accounting Requirements In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory and administrative services, and general office facilities, is payable monthly at the annual rate of 0.40% of the Fund's average daily net assets. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of BNY Mellon and an affiliate of 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 $4,212, for the six months ended June 30, 2007. The Trust has entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide custody, administration and fund accounting services for the Fund. For t hese 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 $55,957 during the six months ended June 30, 2007. The Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Fund's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $2,289 for the six months ended June 30, 2007. See Note 7 for further details. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $3,529, which is included in miscellaneous expenses in the statement of operations for the six months ended June 30, 2007. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2007, the Fund was charged $2,090, which is included in miscellaneous expenses on the statement of operations. No other director, officer or employee of Standish Mellon or its affiliates receives any compensation from the Trust or the Fund for serving as an officer or Trustee of the Trust. The Fund pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee and a per meeting fee, as well as reimbursement for travel and out-of-pocket expenses. In addition, the Trust pays the legal fees for the independent counsel of the Trustees. The 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, 2007, the Fund was charged $497 for fees payable to BNY 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, 2007 were as follows: Purchases Sales --------- ----- U.S. Government Securities $64,395,891 $39,528,036 ----------- ----------- Non-U.S Government Securities $17,493,385 $34,741,094 ----------- ----------- 18 Mellon Institutional Funds Investment Trust Standish Mellon International 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, 2007 December 31, 2006 ---------------- ----------------- Shares sold 1,619,914 686,385 Shares issued to shareholders for reinvestment of distributions 8,437 55,850 Share redeemed (1,258,572) (2,589,759) ---------- ---------- Net increase (decrease) 369,779 (1,847,524) ========== ========== At June 30, 2007, two shareholders of record, in the aggregate, held approximately 58% 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, 2007, the Fund received $47 in redemption fees and is reflected in the cost of shares redeemed. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. In July 2006, FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beg inning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the implications of FIN 48 and determined that it will not have any impact on the financial statements. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $110,051,703 ============ Gross unrealized appreciation 1,587,836 Gross unrealized depreciation (1,585,336) ------------ Net unrealized appreciation (depreciation) $ 2,500 ============ (6) Financial Instruments: In general, the following instruments are used for hedging purposes as described below. However, these instruments may also be used to seek to enhance potential gain in circumstances where hedging is not involved. The Fund may trade the following financial instruments with off-balance sheet risk: 19 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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 t he 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 including counterparties. For the six months ended June 30, 2007, the Fund entered into the following transactions: Written Put Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period -- $ -- Options written 46 8,516 ---------- ---------- Outstanding, end of period 46 $ 8,516 ========== ========== Notional Written Call Option Transactions Amount Premiums --------- -------- Outstanding, beginning of period $ -- $ -- Options written 274,000 28,770 ---------- ---------- Outstanding, end of period $ 274,000 $ 28,770 ========== ========== At June 30, 2007, the Fund held options. See the Schedule of Investments for further details. Forward foreign currency exchange contracts The Fund may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward 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, 2007, the Fund held forward foreign currency exchange contracts. See the Schedule of Investments for further details. Futures contracts The Fund may enter into financial futures contracts for the purchase or sale of securities, or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements, the Fund deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments, shown as variation margin, are made or received by the Fund each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized appreciation/depreciation by the Fund. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with 20 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Fund's exposure to the underlying instrument, while selling futures tends to decrease the Fund's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may also arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Fund enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Appreciation and depreciation 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, 2007, the Fund held open financial 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 th e 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, the 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. The Fund earns interest on cash set aside as collateral. 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 appreciation or depreciation 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 avail able 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 gains and losses in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gains and losses. 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 dis agree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates. At June 30, 2007, 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 exercis ing its rights to dispose of the collateral. The Fund also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Fund's obligations due on the loans. The Fund loaned securities during the six months ended June 30, 2007 and earned interest on the invested collateral of $131,515 of which, $126,234 was rebated to borrowers or paid in fees. At June 30, 2007, the Fund had securities valued at $303,360 on loan. See the Schedule of Investments for further detail on the security positions on loan and collateral held. 21 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income 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 Fund 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, 2007, 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. The Fund/Portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating fund/portfolio. For the six months ended June 30, 2007, the expense allocated to the Fund was $3,130. The facility fee and interest expense are included in the miscellaneous expenses on the Statement of Operations. For the six months ended June 30, 2007, the Fund had average b orrowings outstanding of $1,908,714 for a total of seven days and incurred $2,161 of interest expense. At June 30, 2007 the Fund had no borrowings outstanding. 22 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their age, 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, 2007.

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, 2007 to June 30, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value January 1, 2007 January 1, 2007 June 30, 2007 to June 30, 2007 - -------------------------------------------------------------------------------------------------------------- Actual $1,000.00 $ 989.60 $3.70 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). 3 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Portfolio Information as of June 30, 2007 (Unaudited) - -------------------------------------------------------------------------------- Summary of Combined Ratings - ------------------------------------------------------- Percentage of Quality Breakdown Investments - ------------------------------------------------------- AAA and higher 66.7% AA 8.6 A 11.7 BBB 6.4 BB 3.0 B 3.6 ----- 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. Effective May 1, 2007, the Board approved Fund strategy changes to ease limits on investments in emerging markets and high yield investments and lower the minimum average credit quality of the Fund. Specifically, the changes: (i) increased the limitations on high yield exposure from 15% to 25% of Fund's total assets; (ii) changed the description of the Fund's average credit quality from a "target in the range of A to AA/Aa" to "a minimum of A-/A3" and (iii) increased the general limitation on investing in issuers located in emerging markets from 10% to 25% of the total assets of the Fund. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last quoted bid price. Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Fund's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Fund's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. Exchange traded options and futures are valued at the settlement price determined by the relevant exchange. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers, including counterparties, or pricing services. Because foreign markets may be open at different times than the NYSE, the value of the Fund's shares may change on days when shareholders are not able to buy or sell them. Many securities markets and exchanges outside the U.S. close prior to the close of the NYSE and therefore the closing prices for securities in such markets or on such exchanges may not fully reflect the events that occur after such close but before the close of the NYSE. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Fund acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity when required for federal income tax purposes. Dividend income is recorded on the ex-dividend date. Realized gain and loss 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 appreciation or depreciation from investments. Net realized appreciation (depreciation) 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. 16 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- C. Distributions to Shareholders Distributions to shareholders are recorded on the ex-dividend date. The Fund's distributions from capital gains, if any, after reduction of capital losses will be declared and distributed at least annually. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for foreign currency transactions, losses deferred due to wash sales, post-October losses, amortization and/or accretion of premiums and discounts on certain securities, amortization of swap premium and the timing of recognition of realized and unrealized appreciation and depreciation 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. D. Foreign currency transactions The Fund maintains its books and records in U.S. dollars. Investment security valuations, other assets, and liabilities initially expressed in foreign currencies are converted into U.S. dollars based upon current currency exchange rates. Purchases and sales of foreign investment securities and income and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. E. Foreign investment risk There are certain additional risks involved in investing in foreign securities that are not inherent in investments in domestic securities. These risks may involve adverse political and economic developments, including the possible imposition of capital controls or other foreign governmental laws or restrictions. In addition, the securities of some foreign companies and securities markets are less liquid and at times may be more volatile than securities of comparable U.S. companies and U.S. securities markets. The risks described above apply to an even greater extent to investments in emerging markets. The securities markets of emerging countries are generally smaller, less developed, less liquid, and more volatile than the securities markets of the U.S. and developed foreign markets. F. Commitments and contingencies In the normal course of business, the 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. G. Expenses The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated among funds of the Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds. H. Affiliated issuers Affiliated issuers are investment companies advised by Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of The Bank of New York Mellon Corporation ("BNY Mellon"), or its affiliates. 17 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- I. New Accounting Requirements In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory and administrative services, and general office facilities, is 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, 2007. Pursuant to this agreement, for the six months ended June 30, 2007, Standish Mellon voluntarily waived a portion of its investment advisory fee in the amount of $34,482. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as, out-of-pocket expenses. Pursuant to this agreement the Fund was charged $3,521, for the six months ended June 30, 2007. The Trust has entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide custody, administration and fund accounting services for the Fund. For these services the Fund pays Mellon Bank a fixed fee plus asset and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement the Fund was charged $45,627 during the six months ended June 30, 2007. The Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Fund's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $337 for the six months ended June 30, 2007. See Note 7 for further details. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2007, the Fund was charged $2,090, which is included in miscellaneous expenses on the statement of operations. No other director, officer or employee of Standish Mellon or its affiliates receives any compensation from the Trust or the Fund for serving as an officer or Trustee of the Trust. The Fund pays each Trustee who is not a director, officer or employee of Standish Mellon or its affiliates an annual fee and a per meeting fee, as well as reimbursement for travel and out-of-pocket expenses. In addition, the Trust pays the legal fees for the independent counsel of the Trustees. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $1,386, which is included in miscellaneous expenses in the statement of operations for the six months ended June 30, 2007. The Fund pays administrative service fees. These fees are paid to affiliated or unaffiliated retirement plans, omnibus accounts and platform administrators and other entities ("Plan Administrators") that provide record keeping and/or other administrative support services to accounts, retirement plans and their participants. As compensation for such services, the Fund may pay each Plan Administrator an administrative service fee in an amount of up to 0.15% (on an annualized basis) of the Fund's average daily net assets attributable to Fund shares that are held in accounts serviced by such Plan Administrator. The Fund's adviser or its affiliates may pay additional compensation from their own resources to Plan Administrators and other entities for administrative services, as well as in consideration of marketing or other distribution-related services. These payments may provide an incentive for these entities to actively promote the Fund or cooperate with the distributor's promotional efforts. For the six months ended June 30, 2007, the Fund was charged $2,537 for fees payable to BNY 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, 2007 were as follows: Purchases Sales ----------- ----------- U.S. Government Securities $13,592,704 $11,080,722 ----------- ----------- Non-U.S Government Securities $ 6,620,390 $10,683,754 ----------- ----------- 18 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II 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, 2007 December 31, 2006 --------------- ----------------- Shares sold 98,314 481,319 Shares issued to shareholders for reinvestment of distributions 24,545 7,591 Share redeemed (153,468) (914,029) -------- -------- Net increase (decrease) (30,609) (425,119) ======== ======== At June 30, 2007, one shareholder of record held approximately 65% of the total outstanding shares of the Fund. Investment activities of this shareholder could have a material impact on the Fund. The Fund imposes a redemption fee of 2% of the net asset value of the shares, with certain exceptions, which are redeemed or exchanged less than 30 days from the day of their purchase. The redemption fee is paid directly to the Fund, and is designed to offset brokerage commissions, market impact, and other costs associated with short-term trading in the Fund. The fee does not apply to shares that were acquired through reinvestment of distributions. For the six months ended June 30, 2007, the Fund did not assess any redemption fees. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. In July 2006, FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the implications of FIN 48 and determined that it will not have any impact on the financial statements. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $40,507,543 =========== Gross unrealized appreciation 750,642 Gross unrealized depreciation (696,070) ----------- Net unrealized appreciation (depreciation) $ 54,572 =========== (6) Financial Instruments: In general, the following instruments are used for hedging purposes as described below. However, these instruments may also be used to seek to enhance potential gain in circumstances where hedging is not involved. The Fund may trade the following financial instruments with off-balance sheet risk: Options Call and put options give the holder the right to purchase or sell a security or currency or enter into a swap arrangement on a future date at a specified price. The Fund may use options to seek to hedge against risks of market exposure and changes in security prices and foreign currencies, as well as to seek to enhance returns. Writing puts and buying calls tend to increase the Fund's exposure to the underlying instrument. Buying puts and 19 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- 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 including counterparties. For the six months ended June 30, 2007, the Fund entered into the following transactions: Number of Written Put Option Transactions Contracts Premiums --------- -------- Outstanding, beginning of period -- $ -- Options written 18 3,332 ------- ------- Outstanding, end of period 18 $ 3,332 ======= ======= Notional Written Call Option Transactions Amount Premiums --------- -------- Outstanding, beginning of period $ -- $ -- Options written 116,800 12,264 -------- ------- Outstanding, end of period $116,800 $12,264 ======== ======= At June 30, 2007, the Fund held options. See the Schedule of Investments for further details. Forward foreign currency exchange contracts The Fund may enter into forward foreign currency and cross currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar and other foreign currencies. The forward foreign currency and cross currency exchange contracts are marked to market using the forward foreign currency rate of the underlying currency and any appreciation or depreciation are recorded for financial statement purposes as unrealized until the contract settlement date or upon the closing of the contract. Forward 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, 2007, the Fund held forward foreign currency exchange contracts. See the Schedule of Investments for further details. Futures contracts The Fund may enter into financial futures contracts for the purchase or sale of securities, or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements, the Fund deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments, shown as variation margin, are made or received by the Fund each day depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized appreciation/depreciation by the Fund. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends 20 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- to increase the Fund's exposure to the underlying instrument, while selling futures tends to decrease the Fund's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may also arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Fund enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Appreciation and depreciation 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, 2007, the Fund held open financial 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, the 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. The Fund earns interest on cash set aside as collateral. 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 appreciation or depreciation 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 gains and losses in the Statement of Operations. Net payments of interest on interest rate swap agreements, if any, are included as part of realized gains and losses. 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, 2007, 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 also bears the risk in the event that the interest and/or dividends received on invested collateral is not sufficient to meet the Fund's obligations due on the loans. The Fund loaned securities during the six months ended June 30, 2007 and earned interest on the invested collateral of $26,153 of which, $25,380 was rebated to borrowers or paid in fees. At June 30, 2007, the Fund did not have any securities on loan. 21 Mellon Institutional Funds Investment Trust Standish Mellon International Fixed Income Fund II 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 Fund 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, 2007, 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. The Fund/Portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating fund/portfolio. For the six months ended June 30, 2007, the fund was not charged a fee. The facility fee and interest expense are included in the miscellaneous expenses on the Statement of Operations. For the six months ended June 30, 2007, the Fund had average borrowings outstanding of $278,000 for a total of two days and incurred $90 of interest expense. At June 30, 2007 the Fund had no borrowings outstanding. (10) Subsequent Event: On June 22, 2007, the Board of Trustees of the Trust considered and approved a proposal to liquidate and dissolve the Fund. It is currently expected that the liquidation and dissolution of the Fund would be effective on or before the close of business on October 31, 2007. 22 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their age, 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, 2007.

Mellon Institutional Funds Investment Trust Standish Mellon Yield Plus 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, 2007 to June 30, 2007). Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000.00=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Expenses Paid Beginning Ending During Period+ Account Value Account Value January 1, 2007 January 1, 2007 June 30, 2007 to June 30, 2007 - -------------------------------------------------------------------------------- Actual $1,000.00 $1,016.60 $2.00 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). The example reflects the combined expenses of the Fund and the master portfolio in which it invests all its assets. 3 Mellon Institutional Funds Investment Trust Standish Mellon Yield Plus Fund Portfolio Information as of June 30, 2007 (Unaudited) - -------------------------------------------------------------------------------- The Standish Mellon Yield Plus Fund invests all of its investable assets in an interest of the Standish Mellon Yield Plus Portfolio (See Note 1 of the Fund's Notes to Financial Statements).

Standish Mellon Yield Plus Fund (the "Fund") is a separate diversified investment series of the Trust. The objective of the Fund is to achieve a high level of current income consistent with preserving principal and liquidity. The Fund invests all of its investable assets in an interest of Standish Mellon Yield Plus Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which is organized as a New York trust and has the same investment objective as the Fund. The Portfolio seeks to achieve its objective by investing, under normal circumstances, at least 80% of net assets in 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, 2007). The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is open. The Fund records its investments in the Portfolio at value. The Portfolio values its securities at value as discussed in Note 1A of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. B. Securities transactions and income The Fund's investments in the Portfolio are recorded on settlement date. The Portfolio's securities transactions are recorded as of the trade date as discussed in Note 1B of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. Currently, the Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolio, less all expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. All realized and unrealized gains and losses of the Fund represent pro rata shares of gains and losses of the Portfolio. C. Distributions to shareholders Distributions to shareholders are recorded on the ex-dividend date. The Fund's distributions from capital gains, if any, after reduction of capital losses are declared and distributed at least annually. In determining the amounts of its dividends, the Fund will take into account its share of the income, gains or losses, expenses, and any other tax items of the Portfolio. Dividends from net investment income and distributions from capital gains, if any, are reinvested in additional shares of the Fund unless a shareholder elects to receive them in cash. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. These differences, which may result in reclassifications, are primarily due to differing treatments for losses deferred due to post-October losses, capital loss carryovers, and the timing of recognition of realized and unrealized gains and losses on futures contracts. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications among undistributed net investment income(loss), accumulated net realized gain (loss) and paid in capital. Undistributed net investment income (loss) and accumulated net realized gain (loss) on investments may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or gain remaining at fiscal year end is distributed in the following year. D. Expenses The majority of expenses of the Trust or Portfolio Trust are directly identifiable to an individual fund or portfolio. Expenses which are not readily identifiable to a specific fund or portfolio are allocated among funds of the Trust and/or portfolios of the Portfolio Trust taking into consideration, among other things, the nature and type of expense and the relative size of the funds or portfolios. 9 Mellon Institutional Funds Investment Trust Standish Mellon Yield Plus Fund Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- E. Commitments and contingencies In the normal course of business, the Fund may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Fund under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risks of loss to be remote. F. New accounting requirements In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The Fund does not directly pay any investment advisory fees, but indirectly bears its pro rata share of the compensation paid by the Portfolio to Standish Mellon Asset Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of The Bank of New York Mellon Corporation ("BNY Mellon"), 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 0.40% of the Fund's average daily net assets. Pursuant to this agreement, for the six months ended June 30, 2007, Standish Mellon voluntarily reimbursed the Fund for $35,420 of its operating expenses. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly-owned subsidiary of The Dreyfus Corporation, a wholly-owned subsidiary of BNY Mellon and an affiliate of Standish Mellon , to provide personnel and facilities to perform transfer agency and certain shareholder services for the Fund. For these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based fees, as well as out-of-pocket expenses. Pursuant to this agreement, the Fund was charged $3,152 for the six months ended June 30, 2007. The Trust has contracted Mellon Investor Services LLC, a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $1,100 for the six months ended June 30, 2007, which is included in miscellaneous expenses in the statement of operations. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's Chief Compliance Officer. For the six months ended June 30, 2007, the Fund was charged $2,078. No other director, officer or employee of Standish Mellon or its affiliates receives any compensation from the Trust or the Portfolio Trust for serving as an officer or Trustee of the Trust. The Fund pays each Trustee who is not a director, officer or employee of 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, 2007, the Fund was charged $938 for fees payable to BNY Mellon Private Wealth Management. Effective June 30, 2007, MBSC Securities Corporation ("MBSC"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish, replaced Mellon Funds Distributor, L.P. as the Fund's principal distributor. (3) Investment Transactions: Increases and decreases in the Fund's investment in the Portfolio for the six months ended June 30, 2007 aggregated $11,302,141 and $7,560,583, 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. 10 Mellon Institutional Funds Investment Trust Standish Mellon Yield Plus 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, 2007 December 31, 2006 ---------------- ----------------- Shares sold 563,603 299,660 Shares issued to shareholders for reinvestment of distributions 26,803 64,517 Shares redeemed (366,739) (1,268,985) ---------- ---------- Net increase (decrease) 223,667 (904,808) ========== ========== At June 30, 2007, three shareholders of record held, in the aggregate, approximately 56% 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, 2007, the Fund did not receive redemption fees. (5) Federal Taxes: Each year, the Fund intends to qualify as a "regulated investment company" under Subchapter M of the Code. As such and by complying with the applicable provisions of the Code regarding the sources of its income, the timely distributions of its income to its shareholders, and the diversification of its assets, the Fund will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain which are distributed to shareholders. In July 2006, the FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the implications of FIN 48 and determined that it will not have any impact on the financial statements. See the corresponding master portfolio for tax basis unrealized appreciation (depreciation) information. 11 Mellon Institutional Funds Master Portfolio Standish Mellon Yield Plus Portfolio Schedule of Investments -- June 30, 2007 (Unaudited) - -------------------------------------------------------------------------------- Par Value Security Rate Maturity Value (Note 1A) - ------------------------------------------------------------------------------------------------------------------- UNAFFILIATED INVESTMENTS--72.7% BONDS AND NOTES--69.0% Asset Backed--51.9% Accredited Mortgage Loan Trust 2006-2M7(a) 6.170% 9/25/2036 USD 250,000 $ 196,750 Advanta Business Card Master Trust 2005-C1 C1 (a) 5.830 8/22/2011 500,000 501,869 American Express Issuance Trust 2005-1 C (a) 5.650 8/15/2011 500,000 502,080 Asset Backed Funding Certificates 2005-WMC1 M4 (a) 5.910 6/25/2035 500,000 499,996 Asset Backed Securities Corp.

Standish Mellon Yield Plus 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, 2007 there was one fund, Standish Mellon Yield Plus 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, 2007 was 100%. The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. Investment security valuations Securities are valued at the last sale prices on the exchange or national securities market on which they are primarily traded. Securities not listed on an exchange or national securities market, or securities for which there were no reported transactions, are valued at the last quoted bid price. Securities that are fixed income securities, other than short-term instruments with less than sixty days remaining to maturity, for which market prices are readily available, are valued at their current market value on the basis of quotations, which may be furnished by a pricing service or dealers in such securities. Securities (including illiquid securities) for which quotations are not readily available are valued at their fair value as determined in good faith under consistently applied procedures under the general supervision of the Trustees. With respect to any portion of the Portfolio's assets that are invested in one or more open-end regulated investment companies ("RICs"), the Portfolio's net asset value ("NAV") will be calculated based upon the NAVs of such RICs. Exchange traded options and futures are valued at the settlement price determined by the relevant exchange. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers, including counterparties, or pricing services. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Portfolio acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and then is valued at amortized cost based upon the value on such date unless the Trustees determine during such sixty-day period that amortized cost does not represent fair value. B. Securities transactions and income Securities transactions are recorded as of the trade date. Interest income is determined on the basis of coupon interest earned, adjusted for accretion of discount or amortization of premium using the yield-to-maturity method on long-term debt securities and short-term securities with greater than sixty days to maturity when required for federal income tax purposes. Dividend income is recorded on the ex-dividend date. Realized gains and losses from securities sold are recorded on the identified cost basis. Dividends representing a return of capital are reflected as a reduction of cost. C. Income taxes The Portfolio is treated as a disregarded entity for U.S. federal income tax purposes and consequently, each corresponding Feeder Fund that invests in a Portfolio is treated for U.S. federal income tax purposes as owning all of the underlying assets of such Portfolio. No provision is made by the Portfolio for federal or state income taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes. Since the Portfolio's investor is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the source of income and diversification requirements applicable to regulated investment companies (under the Internal Revenue Code) in order for its investors to satisfy them. 19 Mellon Institutional Funds Master Portfolio Standish Mellon Yield Plus 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 The Bank of New York Mellon Corporation ("BNY Mellon"), or its affiliates. G. New Accounting Requirements In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 157 and its impact, if any, in the financial statements has not yet been determined. (2) Investment Advisory Fee and Other Transactions with Affiliates: The investment advisory fee paid to Standish Mellon for overall investment advisory, 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 annual operating expenses of the Fund and its pro rata share of the Portfolio's expenses (excluding brokerage commissions, taxes and extraordinary expenses) to 0.40% of the Fund's average daily net assets. Pursuant to this agreement, for the six months ended June 30, 2007, Standish Mellon voluntarily waived a portion of its investment advisory fee in the amount of $14,695. This agreement is voluntary and temporary and may be discontinued or revised by Standish Mellon at any time. The Portfolio Trust has entered into an agreement with Mellon Bank, N.A. ("Mellon Bank"), a wholly owned subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide custody, administration and fund accounting services for the 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 $23,146 for the six months ended June 30, 2007. The Portfolio Trust also entered into an agreement with Mellon Bank to perform certain securities lending activities and to act as the Portfolio's lending agent. Mellon Bank receives an agreed upon percentage of the net lending revenues. Pursuant to this agreement, Mellon Bank earned $21 for the six months ended June 30, 2007. See Note 6 for further details. The Trust reimburses BNY Mellon Asset Management for a portion of the salary of the Trust's and Portfolio Trust's Chief Compliance Officer. No other director, officer or employee of 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, 2007 were as follows: Purchases Sales ------------ ------------ U.S. Government Securities $ -- $ 243,575 ------------ ------------ Non-U.S. Government Securities $ 7,551,775 $ 3,438,670 ============ ============ 20 Mellon Institutional Funds Master Portfolio Standish Mellon Yield Plus Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (4) Federal Taxes: In July 2006, FASB issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Portfolio, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the implications of FIN 48 and determined that it will not have any impact on the financial statements. The cost and unrealized appreciation (depreciation) in value of the investment securities owned at June 30, 2007, as computed on a federal income tax basis, were as follows: Cost for federal income tax purposes $ 25,927,406 ============ Gross unrealized appreciation 27,462 Gross unrealized depreciation (255,258) ------------ Net unrealized appreciation (depreciation) $ (227,796) ============ (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 purchase or sale of securities, or contracts based on financial indices at a fixed price on a future date. Pursuant to margin requirements, the Portfolio deposits either cash or securities in an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the Portfolio each day, depending on the daily fluctuations in the value of the underlying security, and are recorded for financial statement purposes as unrealized appreciation or depreciation by the Portfolio. There are several risks in connection with the use of futures contracts as a hedging device. The change in value of futures contracts primarily corresponds with the value of their underlying instruments or indices, which may not correlate with changes in the value of hedged investments. Buying futures tends to increase the Portfolio's exposure to the underlying instrument, while selling futures tends to decrease the Portfolio's exposure to the underlying instrument or hedge other investments. In addition, there is the risk that the Portfolio may not be able to enter into a closing transaction because of an illiquid secondary market. Losses may also arise if there is an illiquid secondary market or if the counterparty does not perform under the contract's terms. The Portfolio enters into financial futures transactions primarily to seek to manage its exposure to certain markets and to changes in securities prices and foreign currencies. Gains and losses are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. At June 30, 2007, 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 is not sufficient to meet the Portfolio's obligations due on the loans. The Portfolio loaned securities during the six months ended June 30, 2007 and earned interest on the invested collateral of $3,635 of which, $3,585 was rebated to borrowers or paid in fees. At June 30, 2007, the Portfolio had no securities on loan. 21 Mellon Institutional Funds Master Portfolio Standish Mellon Yield Plus Portfolio Notes to Financial Statements (Unaudited) - -------------------------------------------------------------------------------- (7) Line of Credit: The Portfolio, and other subtrusts in the Portfolio Trust and funds in the Trust are parties to a committed line of credit facility, which enables each portfolio/fund to borrow, in the aggregate, up to $35 million. Interest is charged to each participating portfolio/fund based on its borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1% on the committed amount, is allocated ratably among the participating portfolios/funds at the end of each quarter. The Fund/Portfolio also pays an annual renewal fee, computed at a rate of 0.020 of 1% of the committed amount and allocated ratably to the participating funds/portfolios. For the six months ended June 30, 2007, the Portfolio was not charged a fee. For the six months ended June 30, 2007, the Portfolio did not borrow from the credit line. (8) Subsequent Event: On June 22, 2007, the Board of Trustees of the Trust considered and approved a proposal to liquidate and dissolve the Fund. If the shareholders of record of the Fund approve these actions at a meeting anticipated to be held in late September 2007, the Fund will be liquidated and dissolved as soon as practicable thereafter. It is currently expected that the liquidation and dissolution of the Fund would be effective on or before the close of business on October 26, 2007. 22 Trustees and Officers (Unaudited) The following table lists the Trust's trustees and officers; their age, 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, 2007.
