MELLON INSTITUTIONAL FUNDS


February 2008

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2007.

The financial markets experienced a major bout of volatility in 2007 stemming
from two principal sources: troubles in the credit markets related to the
difficulties experienced by mortgage securities backed by subprime loans, and
the high degree of leverage employed by many hedge funds, whose impact on the
markets has swollen significantly over the past decade. While the S&P 500 Index
managed to gain 3.5% in 2007 in a very volatile environment, it lost 3.8% in the
fourth quarter. The U.S. Federal Reserve Board was concerned with market
instability enough to lower rates three times in 2007 even as confidence in the
dollar reached new lows. In December, central banks coordinated their efforts to
provide liquidity facilities to institutions with impaired assets.

Credit markets responded to the subprime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities, resulting in a
significant steepening of the yield curve. In a dramatic repricing of risk,
spreads widened in the corporate bond sector compared to Treasury issues, which
has the effect of making corporate borrowing more expensive. In another
indication of just how disruptive this period was in the credit markets, even
some issuers of commercial paper - typically viewed as the safest segment of the
corporate market - had trouble issuing or rolling over their issues.

Liquidity has slowly returned to the bond markets in general, but it is still
less than normal. The financial and mortgage sectors clearly have been shaken,
and this will likely exacerbate the housing recession as banks become more
restrictive in their lending. In the view of some, the likelihood of a broader
U.S. recession has become greater; indeed, some economists maintain that we have
already entered one. Our view is that a period of diminished growth - around
1.5% to 2% GDP growth in 2008 vs. the 2.5% long-term trend - is more likely. We
see U.S. exports boosted by the weaker dollar, multi-year global economic
expansion and monetary growth, and reasonable corporate profitability -
especially for multinational franchises - as being positives that may partially
offset the drag of the housing sector and lower consumption. However, should the
"credit crunch" intensify - contrary to our expectations - the odds would favor
a full-scale recession.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,
J. David Officer
President

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

As we began 2007, while the weakness in housing was a drag on the economy, the
risk of a recession was small given a low unemployment rate to support consumer
spending, solid corporate profits, and strong global growth. Additionally, a
weaker dollar boosted U.S. export growth and largely offset housing related
weakness. Despite inflation risks from higher energy prices, the level of core
inflation had fallen over the previous twelve months. However, as we progressed
through the year, mounting loss expectations due to rising subprime mortgage
delinquencies exacerbated the market's illiquidity. Risk aversion quickly spread
to other areas of the fixed income market. Global markets were also hit by the
subprime contagion as banks in Europe and the U.K. began reporting large
mortgage related losses. Commercial paper markets ground to a halt as investors
pulled back from asset backed commercial paper conduits and structured
investment vehicles due to their subprime mortgage holdings. To address the
liquidity crunch, central banks in Europe and the U.S. intervened by injecting
large sums of cash reserves. In August, and the months that followed, the U.S.
Federal Reserve Board also stepped up with 100 and 150 basis point reduction in
both the federal funds and discount rates, respectively. Despite the Fed's
intervention, risk aversion has remained quite high as banks and brokers pulled
back in their lending. Amid severe tightening in credit conditions and a slowing
economy, there has been a massive flight into Treasuries. The yield curve has
steepened substantially with the two-year Treasury yield ending the year 176
basis points lower at 3.05% while the ten-year Treasury yield declined 67 basis
points to 4.02%.

For 2007, the Standish Mellon Fixed Income Fund returned 3.64%, underperforming
its benchmark, the Lehman Brothers Aggregate Index, which returned 6.97%. Over
the past year, as risk aversion picked up, broad sectors significantly
underperformed Treasuries. The majority of the lag in the Fund's return as
compared to the benchmark was from its underweight position in Treasuries,
especially in the front end of the yield curve. While the flight to quality
drove Treasury yields much lower, the Fund's holdings in short maturity
corporate bonds, asset backed and commercial mortgage backed sectors did not
participate in the rally. In addition, as we sought to posture the Fund
defensively against leveraged buyout risk, we favored regulated corporate bond
sectors including banks and brokers. However, as the market turmoil escalated,
these sector exposures within the Fund were hardest hit. Spillover from the
subprime mortgage market also caused significantly wider spreads in other
securitized sectors including credit cards, auto loans, commercial mortgage
backed securities and GNMA project loans. With pricing under substantial
pressure across these sectors, performance was negatively impacted. However, the
Fund's longer-than-benchmark duration and bulleted yield curve positioning
contributed positively to the Fund's returns as interest rates fell and the
overweight to intermediate bonds benefited from a much steeper yield curve.

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

With much uncertainty in this environment, we remain cautious in our outlook.
Growth prospects in the U.S. are weak with a prolonged housing downturn and
slowdown in job gains. Globally, we also expect growth to decelerate due to a
drag from higher energy prices and a substantial slowdown in the U.S. Combined
with tighter credit conditions, we expect the Fed to continue to cut interest
rates in 2008. We are maintaining the Fund's overweight in intermediate bonds to
capitalize on a steeper yield curve. Internationally, we anticipate that
interest rates will likely fall, particularly in the U.K. and Europe, which will
provide an opportunity potentially to add duration in these markets. Gradually,
we expect the Fed's accommodative policy actions will restore liquidity to the
market. At that juncture, given much wider risk premiums, there should be
attractive buying opportunities among non-Treasury assets.

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

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

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (July 1, 2007 to December 31, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

(+)  Expenses are equal to the Fund's annualized expense ratio of 0.50%,
     multiplied by the average account value over the period, multiplied by
     184/365 (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.

                       Standish Mellon Fixed Income Fund

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

(1)  Organization and Significant Accounting Policies:

     Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon 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 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.

     Prior to October 26, 2007, the Fund had invested substantially all of its
     investable assets in Standish Mellon Fixed Income Portfolio (the
     "Portfolio"), a subtrust of the Mellon I nstitutional Funds Master
     Portfolio, a New York trust. The Portfolio had investment objectives,
     policies and limitations substantially identical to those of the Fund. On
     October 25, 2007, the Fund, which had owned 100% of the Portfolio on such
     date, withdrew entirely from the Portfolio and received the Portfolio's
     assets, including securities and cash, and assumed its stated liabilities,
     in exchange for its interest in the Portfolio. This redemption in kind
     transaction was effected based upon the net asset value of the Fund's
     interest in the Portfolio. Effective October 26, 2007, the Fund began
     investing directly in securities. Accordingly, the financial statements of
     the Fund and Portfolio have been presented on a consolidated basis, and
     represent all the activities of both the Fund and the Portfolio.

     The following is a summary of significant accounting policies followed by
     the Fund in the preparation of its financial statements. The preparation of
     financial statements in accordance with accounting principl es 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 registered investment companies ("RICs"), the Fund's net
     asset value ("NAV") will be calculated based upon the NAVs of such RICs.

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

     Short-term instruments with less than sixty days remaining to maturity are
     valued at amortized cost, which approximates market value. If the Fund
     acquires a short-term instrument with more than sixty days remaining to its
     maturity, it is valued at current market value until the sixtieth day prior
     to maturity and 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.

     Reduced investor demand for mortgage loans and mortgage-related securities
     resulting from delinquencies and losses on residential mortgage loans
     (especially subprime and second-lien mortgage loans) and related market
     events have negatively impacted the performance and market value of certain
     mortgage-related investments and other fixed income securities, and
     increased investor yield requirements. This in turn has resulted in limited
     liquidity in the secondary market for such securities, adversely affecting
     the market value of mortgage-related securities and resulting in higher
     than usual volatility in the credit markets generally. It is possible that
     such limited liquidity in the secondary market for mortgage-related
     securities, and the related credit market volatility, could continue or
     worsen. To the extent that the market for securities in the Fund's
     portfolio becomes illiquid, the Fund might realize upon sale of an affected
     holding substantially less than the amount at which the Fund had previously
     been valuing the security in calculating its net asset value, and the Fund
     may incur substantial losses as a result.

     B.   Securities transactions and income

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

     C.   Distributions to shareholders

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

     E.   Commitments and contingencies

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

     F.   Affiliated issuers

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

     G.   New accounting requirements

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

(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 Fund'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. Standish Mellon voluntarily agreed to limit the total
     operating expenses of the Fund (excluding brokerage commissions, taxes and
     extraordinary expenses) to 0.50% of the Fund's average daily net assets.
     Pursuant to this agreement, for the year ended December 31, 2007, Standish
     Mellon voluntarily waived a portion of its investment advisory fee in the
     amount of $41,745. 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 affi liate 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 $21,061, for the
     year ended December 31, 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 $267,073 for the
     year ended December 31, 2007.

     The Trust, and previously the portfolio, also entered into an agreement
     with Mellon Bank to perform certain securities lending activities and to
     act as the Fund's lending agent. Mellon Bank receives an agreed upon
     percentage of the net lending revenues. Pursuant to this agreement the Fund
     was charged $74,168 for the year ended December 31, 2007. See Note 7 for
     further details.

     The Trust, and previously the Portfolio, entered into two separate
     agreements with The Bank of New York that enables the Fund, and other funds
     in the Trust, to borrow, in the aggregate, (i) up to $35 million from a
     committed line of credit and (ii) up to $15 million from an uncommitted
     line of credit. Interest is charged to each participating fund based on its
     borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
     1%. The participating funds also pay an annual fee, computed at a rate of
     0.020 of 1% of the committed and uncommitted amounts and allocated ratably
     to the participating funds. In addition, a facility fee, computed at an
     annual rate of 0.060 of 1% on the committed amount, is allocated ratably
     among the participating funds at the end of each quarter. Pursuant to these
     agreements, the Fund was charged $1,722 for the year ended December 31,
     2007, which amount is included in miscellaneous expenses on the statement
     of operations. See Note 9 for further details.

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended December
     31, 2007, the Fund was charged $4,324, which amount is included in
     miscellaneous expenses in the statement of operations. No other director,
     officer or employee of Standish Mellon or its affiliates receives any
     compensation from the Trust or the Fund for serving as an officer or
     Trustee of the Trust. The Fund pays each Trustee who is not a director,
     officer or employee of Standish Mellon or its affiliates an annual fee and
     a per meeting fee as well as reimbursement for travel and out-of-pocket
     expenses. In addition, the Trust pays the legal fees for the independent
     counsel of the Trustees.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide
     printing and fulfillment services for the Fund. Pursuant to this agreement,
     the Fund was charged $5,500, which amount is included in miscellaneous
     expenses in the statement of operations for the year ended December 31,
     2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or co operate with the distributor's promotional efforts. For the
     year ended December 31, 2007, the Fund was charged $232,026 for fees
     payable to BNY Mellon Wealth Management.

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

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

(3)  Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended December 31, 2007 were as follows:



                                          Purchases             Sales

(4)  Shares of Beneficial Interest:

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

     At December 31, 2007, two shareholders of record, in the aggregate, held
     approximately 24.9% 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 fiscal years ended December 31, 2007 and December
     31, 2006, the Fund received redemption fees of $8,049 and $4,451,
     respectively.

(5)  Federal Taxes:

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

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

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2007 were as follows:


                                                             
                   Cost for federal income tax purposes         $732,400,622
                                                                ============
                   Gross unrealized appreciation                $  6,385,516
                   Gross unrealized depreciation                 (12,725,277)
                                                                ------------
                   Net unrealized appreciation (depreciation)   $ (6,339,761)
                                                                ============


     The tax character of distributions paid during the fiscal years ended
     December 31, 2007 and December 31, 2006, were as follows:



                                                     2007              2006
                                                 ------------      ------------

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


     At December 31, 2007, the Fund for federal income tax purposes, has capital
     loss carryovers which will reduce the Fund's taxable income arising from
     net realized gain on investments, if any, to the extent permitted by the
     Internal Revenue Code and thus will reduce the amount of distributions to
     shareholders which would otherwise be necessary to relieve the Fund of any
     liability for federal income tax. Such capital loss carryovers are as
     follows:



                             Capital Loss
                              Carry Over          Expiration Date
                              ----------          ---------------
                                                 
                             $118,614,149           12/31/2008
                               36,020,187           12/31/2009
                                  963,957           12/31/2014
                                3,009,464           12/31/2015
                             ------------
                              158,607,757


     At December 31, 2007, $27,099,636 of capital loss carryovers expired. It is
     uncertain whether the Fund will be able to realize the benefits of the
     remaining capital loss carryovers before they expire.

     The Fund elected to defer to its fiscal year ending December 31, 2008,
     $1,691,076 of capital losses and $10,439 of currency losses recognized
     during the period November 1, 2007 to December 31, 2007.

(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:

                                       29

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



     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 s ales
     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 year ended December 31, 2007, the Fund entered into the following
     transactions:

     At December 31, 2007, the Fund held purchased options. See Schedule of
     Investments for further details.

     Futures contracts

     The Fund, and previously the Portfolio, may enter into financial futures
     contracts for the purchase or sale of securities, or contracts based on
     financial indices at a fixed price on a future date. Pursuant to margin
     requirements, the Fund deposits either cash or securities in an amount
     equal to a certain percentage of the contract amount. Subsequent payments
     are made or received by the Fund each day, depending on the daily
     fluctuations in the value of the underlying security, and are recorded for
     financial statement purposes as unrealized appreciation or depreciation by
     the Fund. There are several risks in connection with the use of futures
     contracts as a hedging device. The change in value of futures contracts
     primarily corresponds with the value of their underlying instruments or
     indices, which may not correlate with changes in the value of hedged
     investments. Buying futures tends to increase the Fund's exposure to the
     underlying instrument, while selling futures tends to decrease the Fund's
     exposure to t he underlying instrument or hedge other investments. In
     addition, there is the risk that the Fund may not be able to enter into a
     closing transaction because of an illiquid secondary market. Losses may
     also arise if there is an illiquid secondary market or if the counterparty
     does not perform under the contract's terms.

     The Fund enters into financial futures transactions primarily to seek to
     manage its exposure to certain markets and to changes in securities prices
     and foreign currencies. Gains and losses are realized upon the expiration
     or closing of the futures contracts. Futures contracts are valued at the
     quoted daily settlement prices established by the exchange on which they
     trade.

     At December 31, 2007, the Fund held open financial futures contracts. See
     the Schedule of Investments for further details.

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

     Swap agreements

     The Fund, and previously 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 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 sh ort 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 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 instr uments 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 December 31, 2007, the Fund held open swap agreements. See the Schedule
     of Investments for further details.

(7)  Security Lending:

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

     The Fund, and previously the Portfolio, loaned securities during the year
     ended December 31, 2007 and earned interest on the invested collateral of
     $3,350,524 of which $3,178,260 was rebated to borrowers or paid in fees. At
     December 31, 2007, the Fund had securities valued at $20,698,968 on loan of
     which $15,297,585 was collateralized with cash and $6,030,532 was
     collateralized with highly liquid securities. See Schedule of Investments
     for further detail on the security positions on loan and collateral held.
     See also Note 10.

(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.

                                       31

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

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

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

     At December 31, 2007, the Fund held delayed delivery securities. See the
     Schedule of Investments for further details.

(9)  Line of Credit:

     On behalf of the Fund, and other funds in the Trust, and previously the
     portfolios in the Portfolio Trust, the Trust has access to a credit
     facility, which enables each fund to borrow, in the aggregate, up to $35
     million under a committed line of credit and up to $15 million under an
     uncommitted line of credit. During the year ended December 31, 2007, the
     Fund did not borrow from the credit line.

(10) Restatement:

     The Statement of Assets and Liabilities and Schedule of Investments have
     been restated to correct an error in the manner in which the Fund's
     securities lending agent and custodian accounted for the investment in
     pooled investment vehicles of cash collateral derived from the Fund's
     securities lending activity.

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

     The Fund determined that from December 11, 2007 through the December 31,
     2007 closing date of the financial statements of the Fund and continuing
     until March 10, 2008, the securities lending agent and custodian failed to
     account properly for the Fund's investments in the BlackRock Fund and the
     Dreyfus Fund. Specifically, the securities lending agent and custodian
     maintained, for each series of the Trust, subaccounts reflecting each
     series ownership of shares of the Dreyfus Fund and the BlackRock Fund which
     considered each such series to own a percentage of the Trust series'
     aggregate ownership of the Dreyfus Fund and the BlackRock Fund equal to
     each series' pro rata balance of the aggregate Trust cash collateral in the
     securities lending program, rather than according to each series' specific
     cash purchase and withdrawal activity in shares of the Dreyfus Fund and/or
     the BlackRock Fund. The management of the Trust determined that the
     securities lending agent and custodian should have accounted for these
     inves tments on a Fund specific basis in accordance with actual cash
     purchases and withdrawals. This erroneous methodology caused differences in
     the entries in the Fund's books and records on which the Fund's Schedule of
     Investments and Statement of Assets and Liabilities are based. These
     financial statements have been restated accordingly. (The Fund's annual
     report for the fiscal year ended December 31, 2007 containing these
     financial statements was previously posted on the Trust's website but had
     not been mailed to shareholders or filed with the Commission.) The
     liability listed as "Payable for securities lending collateral investment"
     represents the extent to which the Fund's cash needs to repay collateral
     exceeded the value of its interest in the Dreyfus Fund. The erroneous
     sub-accounting methodology had no effect on the computation of the Fund's
     net asset value.

     Effective March 10, 2008, the accounting for cash collateral investments in
     pooled vehicles was corrected to account for specific purchases and redem
     ptions of interests in such vehicles by the Fund. All activity was
     reprocessed to reflect correct ownership by the Fund in each vehicle and
     the above described financial statements restated accordingly.

                       Standish Mellon Fixed Income Fund

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

To the Trustees of Mellon Institutional Funds Investment Trust and Shareholders
of Standish Mellon Fixed Income Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights, after the restatement
described in Note 10 to the financial statements, present fairly, in all
material respects, the financial position of Standish Mellon Fixed Income Fund
(the "Fund") at December 31, 2007, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with accounting principles generally accepted
in the United States of America. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial state ments in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 2007 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

                  Mellon Institutional Funds Investment Trust
                        Standish Mellon Fixed Income Fund

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

The 1940 Act requires that the Board of Trustees, including a majority of its
Trustees who are not affiliated with the Fund's investment adviser or
underwriter (the "Independent Trustees") voting separately, approve the Fund's
advisory agreement and the related fees on an annual basis. Prior to October 26,
2007, the Fund was not a party to an investment advisory agreement directly with
any investment adviser and did not invest directly in portfolio securities.
Instead, the Fund had invested all of its investable assets in the Standish
Mellon Fixed Income Portfolio (the "Portfolio"), which was managed by Standish
Mellon Asset Management Company LLC ("Standish Mellon" or the "Adviser"). The
Portfolio had investment objectives, policies and limitations substantially
identical to those of the Fund. The Fund's Board of Trustees determined annually
whether the Fund should continue to invest in the Portfolio. The members of the
Fund's Board of Trustees also serve as the Board of Trustees of the Portfolio.
In that c apacity, they considered annually whether to continue the investment
advisory agreement between the Portfolio and Standish Mellon.

In their most recent deliberations concerning their decision to approve the
continuation of the investment advisory agreement, the Board of Trustees
conducted the review and made the determinations that are described below. In
conducting this review and in making such determinations, the Independent
Trustees received from Standish Mellon a broad range of information in response
to a written request prepared on their behalf by their own legal counsel. The
Independent Trustees met alone in a private session with their legal counsel on
September 27, 2007 to review these materials and to discuss the proposed
continuation of the Portfolio's advisory agreement. Representatives of
management attended a portion of the September meeting to provide an overview of
the Adviser's organization, personnel, resources and strategic plans, and to
respond to questions and comments arising from the Independent Trustees' review
of the materials and their deliberations. The entire Board then met on October
30, 2007.

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

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

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

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

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

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

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

Nature, Extent and Quality of Services

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

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

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

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

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

Investment Performance

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

The Board considered the Fund's performance for the one-, three- and five-year
periods ended July 31, 2007 based on the Lipper materials provided to the Board
at the September 27, 2007 meeting. The Board found that the Fund outperformed
its peer group average returns for the one-year period (5.14% vs. 5.13%) and
three-year period (4.26% vs. 3.99%), but underperformed its peer group average
return for the five-year period (4.82% vs. 4.92%).

Advisory Fee and Other Expenses

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

The Portfolio's effective contractual advisory fee was 0.363% (based on the
following breakpoints: 0.40% of the first $250 million; 0.35% of the next $250
million; and 0.30% over $500 million), which was in the 1st (best) quintile of
its peer group of funds, the median fee of which was 0.438%. The Portfolio's net
management fee was 0.378% (which included 0.003% in administrative services fees
under Lipper's calculation methodology), slightly higher than the peer group
median net management fee of 0.375%. Based on the Lipper data, as well as other
factors discussed at the September 27, 2007 meeting, the Board determined that
the Portfolio's advisory fee is reasonable relative to its peer group averages.

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

The Board also considered the Fund's (rather than solely the Portfolio's)
expense ratio and compared it to that of its peer group of similar funds. The
Board found that the actual net expense ratio of 0.495% was higher than the
median net expense ratio of the peer group of 0.47%, largely due to the
Portfolio's small asset size compared to its peer group.

The Adviser's Profitability

The Board considered the Adviser's profitability in managing the Portfolio and
the Fund and the Mellon Institutional Funds as a group, as well as the
methodology used to compute such profitability, and the various direct and
indirect expenses incurred by the Adviser or its affiliated investment advisers
in managing the Portfolio and other funds in the Mellon Institutional Funds
family of funds. The Independent Trustees had observed that the Adviser, based
on the profitability information submitted to them by the Adviser, incurred
losses in managing all but one of the investment companies in the Mellon
Institutional Funds family of funds. The Trustees observed that the Adviser had
experienced profits in operating the Portfolio in both 2005 and 2006 and
concluded these were not excessive.

Economies of Scale

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

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

Other Benefits

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

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

                                     * * *

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

MELLON INSTITUTIONAL FUNDS

February 2008

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2007.

The financial markets experienced a major bout of volatility in 2007 stemming
from two principal sources: troubles in the credit markets related to the
difficulties experienced by mortgage securities backed by subprime loans, and
the high degree of leverage employed by many hedge funds, whose impact on the
markets has swollen significantly over the past decade. While the S&P 500 Index
managed to gain 3.5% in 2007 in a very volatile environment, it lost 3.8% in the
fourth quarter. The U.S. Federal Reserve Board was concerned with market
instability enough to lower rates three times in 2007 even as confidence in the
dollar reached new lows. In December, central banks coordinated their efforts to
provide liquidity facilities to institutions with impaired assets.

Credit markets responded to the subprime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities, resulting in a
significant steepening of the yield curve. In a dramatic repricing of risk,
spreads widened in the corporate bond sector compared to Treasury issues, which
has the effect of making corporate borrowing more expensive. In another
indication of just how disruptive this period was in the credit markets, even
some issuers of commercial paper - typically viewed as the safest segment of the
corporate market - had trouble issuing or rolling over their issues.

Liquidity has slowly returned to the bond markets in general, but it is still
less than normal. The financial and mortgage sectors clearly have been shaken,
and this will likely exacerbate the housing recession as banks become more
restrictive in their lending. In the view of some, the likelihood of a broader
U.S. recession has become greater; indeed, some economists maintain that we have
already entered one. Our view is that a period of diminished growth - around
1.5% to 2% GDP growth in 2008 vs. the 2.5% long-term trend - is more likely. We
see U.S. exports boosted by the weaker dollar, multi-year global economic
expansion and monetary growth, and reasonable corporate profitability -
especially for multinational franchises - as being positives that may partially
offset the drag of the housing sector and lower consumption. However, should the
"credit crunch" intensify - contrary to our expectations - the odds would favor
a full-scale recession.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.


Sincerely,

J. David Officer
President

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

Global sovereign bonds provided solid returns in 2007 while most bonds with a
credit spread suffered. Despite the credit and liquidity crunch, global bonds
provided a year of risk adjusted returns very competitive with the Fund's
benchmark, the Lehman Brothers Global Aggregate Index, which returned 5.33% in
2007. The global bond market continues to be buffeted by concerns about
structured credit, banking sector vulnerabilities, and a potential U.S.
recession. We continue to believe that the U.S. Federal Reserve Board will need
to cut rates further in 2008 as the outlook for the U.S. economy continues to
deteriorate due to a weaker housing market and ongoing turmoil in the structured
credit markets and banking sector.

As we move into 2008, the market has also come to realize that the U.K. housing
market and economy will also likely be hurt significantly by tighter credit
conditions. The front end of the gilt yield curve rallied during the second half
of 2007 and the pound is weaker. The expected U.S. slowdown will, to some
extent, slow growth in Europe and Japan as well. Expectations for a global
decoupling from the U.S. are likely to be disappointed.

Weaker U.S. consumer demand and a depreciated U.S. currency, especially as
compared to the Euro, have reduced net exports for both Europe and Japan.
Furthermore, financial conditions have tightened in Europe as the result of the
credit and liquidity crunch.

However, emerging markets, led by China, India, Brazil, and Russia, continue to
do very well, as do other commodity exporting economies. Nevertheless, we
believe that the U.S. led downturn should take some of the shine off of these
regions' economic performance in 2008.

Performance

The Fund returned 4.30% in 2007, lagging its benchmark, but we believe it is
well positioned for better returns going forward if our "Outlook" below is
accurate. The Fund's underperformance relative to its benchmark in 2007 was
mainly driven by its exposure to the riskier parts of the global bond markets,
such as high yield and emerging market debt.

Even though we are disappointed that the Fund lost ground relative to its
benchmark, we are proud in that we restructured the portfolio in the first half
of 2007 and shed a lot of credit risk. The Fund has always invested heavily in
corporate credits and we avoided almost all of the blowups.

The Fund's main source of credit risk and underperformance has come from its
Northern Rock position. These securities were downgraded to high yield after we
purchased them at distressed levels when they were investment grade. We remain
optimistic, as to these holdings, however, as the restructuring and ownership
situation of the bank gets resolved. Unfortunately the process has taken much
longer than we had expected and so the mark-to-market impact on Fund performance
subtracted nearly 70 basis points.

The remaining drag on performance came from other high yield exposure in short
dated high yield bonds, which we believe will mature at par, and some other
one-off exposures to emerging market debt.

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

On the positive side we had a great year in terms of our country, curve and
duration positioning for the Fund. The Fund consistently invested in the top
performing markets during 2007 which included Japan and Sweden during the first
half and then the U.K. and the U.S. during the second half of 2007.

The Fund was consistently long duration during 2007 which was not helpful during
the first half of 2007 but paid off when the credit crunch and flight to quality
occurred in the summer. We have been long duration in the U.S., Japan and the
U.K., while underweight duration in Europe.

Curve positioning was also helpful in 2007 as we anticipated a steeper yield
curve on the back of Fed rate cuts. We also benefited from a flattening of the
European yield curve even though the European Central Bank was raising interest
rates. The long end of the European yield curve is highly correlated with that
of the U.S. and was dragged lower as the global bond rally intensified late in
2007.

Currency positioning also added about 20 basis points to the portfolio over the
course of 2007 as we held mostly short dollar positions against a wide variety
of currencies.

Outlook

We remain negative on the outlook for the U.S. economy as we believe the
continuing housing market correction will translate into a weaker consumer
sector. We believe that the unemployment rate will increase further over the
coming months, and that this will also slow consumer spending. We believe that a
weaker job market, combined with lower inflation and capacity utilization,
should prompt the Fed to cut rates below 3% in 2008. We are therefore positioned
for lower rates and a steeper yield curve in the U.S. We are also overweight
U.K. duration and have shorted the pound as we expect the British economy to
weaken. In Japan, we are overweight duration as we continue to expect that the
economic recovery will be very gradual. We remain underweight in Europe as
inflation has increasingly become a concern for the European Central Bank.
However, given the uncertain growth outlook, our base case is that rates remain
on hold for a while, so the underweight must be viewed in conjunction with the
U.S. and U.K. overweight positions. We believe growth in several of the smaller
developed economies, like Norway, Sweden, and Australia, will likely remain
relatively robust, and we remain underweight duration in these countries.

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

                    Standish Mellon 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 (July 1, 2007 to December 31, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

- ----------
+ Expenses are equal to the Fund's annualized expense ratio of 0.65%, multiplied
  by the average account value over the period, multiplied by 184/365 (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.

                   Mellon Institutional Funds Investment Trust
                    Standish Mellon Global Fixed Income Fund

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

(1) Organization and Significant Accounting Policies:

    Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
    Massachusetts business trust and is registered under the Investment Company
    Act of 1940, as amended, as an open-end, management investment company.
    Standish Mellon 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 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 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.

    Prior to October 26, 2007, the Fund had invested substantially all of its
    investable assets in Standish Mellon Fixed Income Portfolio (the
    "Portfolio"), a subtrust of the Mellon Institutional Funds Master Portfolio,
    a New York trust. The Portfolio had investment objectives, policies and
    limitations substantially identical to those of the Fund. On October 25,
    2007, the Fund, which owned 100% of the Portfolio on such date, withdrew
    entirely from the Portfolio and received the Portfolio's assets, including
    securities and cash, and assumed its stated liabilities, in exchange for its
    interests in the Portfolio. This redemption in kind transaction was effected
    based upon the net assets value of the Fund's interests in the Portfolio.
    Effective October 26, 2007, the Fund began investing directly in securities.
    Accordingly, the financial statements of the Fund and Portfolio have been
    presented on a consolidated basis, and represent all the activities of both
    the Fund and the Portfolio.

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

    A. Investment security valuations

    Fund shares are valued as of the close of regular trading (normally 4:00
    p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE") is
    open. Securities are valued at the last sale prices on the exchange or
    national securities market on which they are primarily traded. Securities
    not listed on an exchange or national securities market, or securities for
    which there were no reported transactions, are valued at the last 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
    registered investment companies ("RICs"), the Fund's net asset value ("NAV")
    will be calculated based upon the NAVs of such RICs.

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

    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.

    Reduced investor demand for mortgage loans and mortgage-related securities
    resulting from delinquencies and losses on residential mortgage loans
    (especially subprime and second-lien mortgage loans) and related market
    events have negatively impacted the performance and market value of certain
    mortgage-related investments and other fixed income securities, and
    increased investor yield requirements. This in turn has resulted in limited
    liquidity in the secondary market for such securities, adversely affecting
    the market value of mortgage-related securities and resulting in higher than
    usual volatility in the credit markets generally. It is possible that such
    limited liquidity in the secondary market for mortgage-related securities,
    and the related credit market volatility, could continue or worsen. To the
    extent that the market for securities in the Fund's portfolio becomes
    illiquid, the Fund might realize upon sale of an affected holding
    substantially less than the amount at which the Fund had previously been
    valuing the security in calculating its net asset value, and the Fund may
    incur substantial losses as a result.

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

    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 gain or loss
    from investments. Net realized gains and losses on foreign currency
    transactions represent gains and losses on disposition of foreign currencies
    and forward foreign currency exchange contracts, currency gains and losses
    realized between the trade and settlement dates on securities transactions,
    and the difference between the amount of investment income and foreign
    withholding taxes recorded on the Fund's books and the U.S. dollar
    equivalent amounts actually received or paid.

    C. Distributions to shareholders

    Distributions to shareholders are recorded on the ex-dividend date. The
    Fund's distributions from capital gains, if any, after reduction of capital
    losses will be declared and distributed at least annually. Dividends from
    net investment income and distributions from capital gains, if any, are
    reinvested in additional shares of the Fund unless the shareholder elects to
    receive them in cash.

    Income and capital gain distributions are determined in accordance with
    income tax regulations which may differ from accounting principles generally
    accepted in the United States of America. These differences, which may
    result in reclassifications, are primarily due to wash sales, post-October
    losses, amortization of swap premium, timing of recognition of realized and
    unerealized appreciation and depreciation on futures contracts and differing
    treatments for foreign currency transactions.

    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 ("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.

    I. New Accounting Requirements

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

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

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory, administrative services, and general office facilities is paid
     monthly at the annual rate of 0.40% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit the total annual operating
     expenses of the Fund (excluding brokerage commissions, taxes and
     extraordinary expenses) to 0.65% of the Fund's average daily net assets.
     Pursuant to this agreement, for the year ended December 31, 2007, Standish
     Mellon voluntarily waived a portion of its investment advisory fee in the
     amount of $105,228. 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 $5,977, for the
    year ended December 31, 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 $105,751 for the year ended
    December 31, 2007.

     The Trust, and previously the Portfolio, also entered into an agreement
     with Mellon Bank to perform certain securities lending activities and to
     act as the Fund's lending agent. Mellon Bank receives an agreed upon
     percentage of the net lending revenues. Pursuant to this agreement, the
     Fund was charged $3,924 for the year ended December 31, 2007. See Note 7
     for further details.

    The Trust, and previously the Portfolio, entered into two separate
    agreements with The Bank of New York that enables the Fund, and other funds
    in the Trust, to borrow, in the aggregate, (i) up to $35 million from a
    committed line of credit and (ii) up to $15 million from an uncommitted line
    of credit. Interest is charged to each participating fund based on its
    borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
    1%. The participating funds also pay an annual fee, computed at a rate of
    0.020 of 1% of the committed and uncommitted amounts and allocated ratably
    to the participating funds. In addition, a facility fee, computed at an
    annual rate of 0.060 of 1% on the committed amount, is allocated ratably
    among the participating funds at the end of each quarter. Pursuant to these
    agreements, the Fund was charged $2,277 for the year ended December 31,
    2007, which amount is included in miscellaneous expenses on the statement of
    operations. See Note 9 for further details.

    The Trust reimburses BNY Mellon Asset Management for a portion of the salary
    of the Trust's Chief Compliance Officer. For the year ended December 31,
    2007, the Fund was charged $4,294, which amount is included in miscellaneous
    expenses in the statement of operations. No other director, officer or
    employee of Standish Mellon or its affiliates receives any compensation from
    the Trust or the Fund for serving as an officer or Trustee of the Trust. The
    Fund pays each Trustee who is not a director, officer or employee of
    Standish Mellon or its affiliates an annual fee and a per meeting fee as
    well as reimbursement for travel and out-of-pocket expenses. In addition,
    the Trust pays the legal fees for the independent counsel of the Trustees.

    The Trust has contracted Mellon Investor Services LLC, a wholly owned
    subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide
    printing and fulfillment services for the Fund. Pursuant to this agreement,
    the Fund was charged $400, which amount is included in miscellaneous
    expenses in the statement of operations for the year ended December 31,
    2007.

    The Fund may pay administrative service fees. These fees are paid to
    affiliated or unaffiliated retirement plans, omnibus accounts and platform
    administrators and other entities ("Plan Administrators") that provide
    record keeping and/or other administrative support services to accounts,
    retirement plans and their participants. As compensation for such services,
    the Fund may pay each Plan Administrator an administrative service fee in an
    amount of up to 0.15% (on an annualized basis) of the Fund's average daily
    net assets attributable to Fund shares that are held in accounts serviced by
    such Plan Administrator. The Fund's adviser or its affiliates may pay
    additional compensation from their own resources to Plan Administrators and
    other entities for administrative services, as well as in consideration of
    marketing or other distribution-related services. These payments may provide
    an incentive for these entities to actively promote the Fund or cooperate
    with the distributor's promotional efforts. For the year ended December 31,
    2007, the Fund was charged $101 for fees payable to BNY Mellon Wealth
    Management.

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

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

(3) Purchases and Sales of Investments:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended December 31, 2007 were as follows:

(4) Shares of Beneficial Interest:

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

    At December 31, 2007, two shareholders of record, in the aggregate, held
    approximately 93.5% of the total outstanding shares of the Fund. Investment
    activities of these shareholders could have a material impact on the Fund.

    The Fund imposes a redemption fee of 2% of the net asset value of the
    shares, with certain exceptions, which are redeemed or exchanged less than
    30 days from the day of their purchase. The redemption fee is paid directly
    to the Fund, and is designed to offset brokerage commissions, market impact,
    and other costs associated with short-term trading in the Fund. The fee does
    not apply to shares that were acquired through reinvestment of
    distributions. For the fiscal years ended December 31, 2007 and December 31,
    2006, the Fund did not assess any redemption fees.

(5) Federal Taxes:

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

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

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

    The tax basis components of distributable earnings and the federal tax cost
    as of December 31, 2007 were as follows:

    The tax character of distributions paid during the fiscal years ended
    December 31, 2007 and December 31, 2006, were as follows:

    At December 31, 2007, the Fund for federal income tax purposes, has capital
    loss carryovers which will reduce the Fund's taxable income arising from net
    realized gain on investments, if any, to the extent permitted by the
    Internal Revenue Code and thus will reduce the amount of distributions to
    shareholders which would otherwise be necessary to relieve the Fund of any
    liability for federal income tax. Such capital loss carryovers are as
    follows:



    Capital Loss
     Carry Over             Expiration Date
     ----------             ---------------
                            
     $2,034,497                12/31/2008

     ----------
     $6,264,749


    During 2007, the Fund utilized $211,573 in capital loss carryovers. At
    December 31, 2007, $1,834,072 of capital loss carryovers expired. The Fund
    also treated as expired $13,518,811 of capital losses due to limitations
    imposed by the Internal Revenue Service Code related to share ownership
    activity. It is uncertain whether the Fund will be able to realize the
    benefits of the remaining capital loss carryovers before they expire and
    utilization of the remaining capital loss carryovers could be subject to
    future limitations imposed by the Internal Revenue Code related to share
    ownership activity.

    The Fund elected to defer to its fiscal year ending December 31, 2008,
    $19,247 of capital losses during the period November 1, 2007 to December 31,
    2007.

(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, and previously 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 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


                                       23


                   Mellon Institutional Funds Investment Trust
                    Standish Mellon Global Fixed Income Fund

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

    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 year ended December 31, 2007, the Fund entered into the following
    transactions:

    At December 31, 2007, the Fund held a forward volatility option. See the
    Schedule of Investments for further details.

    Forward foreign currency exchange contracts

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

    At December 31, 2007, the Fund held forward foreign currency exchange
    contracts. See the Schedule of Investments for further details.

    Futures contracts

    The Fund, and previously the Portfolio, may enter into financial futures
    contracts for the purchase or sale of securities, or contracts based on
    financial indices at a fixed price on a future date. Pursuant to margin
    requirements, the Fund deposits either cash or securities in an amount equal
    to a certain percentage of the contract amount. Subsequent payments are made
    or received by the Fund each day, depending on the daily fluctuations in the
    value of the underlying security, and are recorded for financial statement
    purposes as unrealized appreciation or depreciation by the Fund. There are
    several risks in connection with the use of futures contracts as a hedging
    device. The change in value of futures contracts primarily corresponds with
    the value of their underlying instruments or indices, which may not
    correlate with changes in the value of hedged investments. Buying futures
    tends to increase the Fund's exposure to the underlying instrument, while
    selling futures tends to decrease the Fund's exposure to the underlying
    instrument or hedge other investments. In addition, there is the risk that
    the Fund may not be able to enter into a closing transaction because of an
    illiquid secondary market. Losses may also arise if there is an illiquid
    secondary market or if the counterparty does not perform under the
    contract's terms.

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

    The Fund enters into financial futures transactions primarily to seek to
    manage its exposure to certain markets and to changes in securities prices
    and foreign currencies. Gains and losses are realized upon the expiration or
    closing of the futures contracts. Futures contracts are valued at the quoted
    daily settlement prices established by the exchange on which they trade.

    At December 31, 2007, the Fund held open financial futures contracts. See
    the Schedule of Investments for further details.

    Swap agreements

    The Fund, and previously 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 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 December 31, 2007, the Fund held open swap agreements. See the Schedule
    of Investments for further details.

(7) Security Lending:

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

    The Fund, and previously the Portfolio, loaned securities during the year
    ended December 31, 2007 and earned interest on the invested collateral of
    $156,867 of which $147,716 was rebated to borrowers or paid in fees. At
    December 31, 2007, the Fund did not have any securities out on loan. See
    also Note 10.

(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.

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

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

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

     At December 31, 2007, the Fund had delayed delivery securities. See the
     Schedule of Investments for further details.

(9)  Line of Credit:

     On behalf of the Fund, and other funds in the Trust, and previously the
     portfolios in the Portfolio Trust, the Trust has access to a credit
     facility, which enables each fund to borrow, in the aggregate, up to $35
     million under a committed line of credit and up to $15 million under an
     uncommitted line of credit. During the year ended December 31, 2007, the
     Fund and the Portfolio had combined average borrowings outstanding of
     $2,395,333 for a total of six days and incurred $2,327 of interest expense.
     At December 31, 2007, the Fund did not have an outstanding loan balance.

(10) Restatement:

     The Statement of Assets and Liabilities and Schedule of Investments have
     been restated to correct an error in the manner in which the Fund's
     securities lending agent and custodian accounted for the investment in
     pooled investment vehicles of cash collateral derived from the Fund's
     securities lending activity.

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

     The Fund determined that from December 11, 2007 through the December 31,
     2007 closing date of the financial statements of the Fund and continuing
     until March 10, 2008, the securities lending agent and custodian failed to
     account properly for the Fund's investments in the BlackRock Fund and the
     Dreyfus Fund. Specifically, the securities lending agent and custodian
     maintained, for each series of the Trust, subaccounts reflecting each
     series ownership of shares of the Dreyfus Fund and the BlackRock Fund which
     considered each such series to own a percentage of the Trust series'
     aggregate ownership of the Dreyfus Fund and the BlackRock Fund equal to
     each series' pro rata balance of the aggregate Trust cash collateral in the
     securities lending program, rather than according to each series' specific
     cash purchase and withdrawal activity in shares of the Dreyfus Fund and/or
     the BlackRock Fund. The management of the Trust determined that the
     securities lending agent and custodian should have accounted for these
     investments on a Fund specific basis in accordance with actual cash
     purchases and withdrawals. This erroneous methodology caused differences in
     the entries in the Fund's books and records on which the Fund's Schedule of
     Investments and Statement of Assets and Liabilities are based. These
     financial statements have been restated accordingly. (The Fund's annual
     report for the fiscal year ended December 31, 2007 containing these
     financial statements was previously posted on the Trust's website but had
     not been mailed to shareholders or filed with the Commission.) The
     liability listed as "Payable for securities lending collateral investment"
     represents the extent to which the Fund's cash needs to repay collateral
     exceeded the value of its interest in the Dreyfus Fund. The erroneous
     sub-accounting methodology had no effect on the computation of the Fund's
     net asset value.

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

     Effective March 10, 2008, the accounting for cash collateral investments in
     pooled vehicles was corrected to account for specific purchases and
     redemptions of interests in such vehicles by the Fund. All activity was
     reprocessed to reflect correct ownership by the Fund in each vehicle and
     the above described financial statements restated accordingly.

     The amounts as originally reported and as restated are as follows:

                    Standish Mellon Global Fixed Income Fund

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

To the Trustees of Mellon Institutional Funds Investment Trust and Shareholders
of Standish Mellon Global Fixed Income Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights, after the restatement
described in Note 10 to the financial statements, present fairly, in all
material respects, the financial position of Standish Mellon Global Fixed Income
Fund (the "Fund") at December 31, 2007, the results of its operations for the
year then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with accounting principles generally accepted
in the United States of America. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 2007 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

                   Mellon Institutional Funds Investment Trust
                    Standish Mellon Global Fixed Income Fund

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

     The 1940 Act requires that the Board of Trustees, including a majority of
     its Trustees who are not affiliated with the Fund's investment adviser or
     underwriter (the "Independent Trustees") voting separately, approve the
     Fund's advisory agreement and the related fees on an annual basis. Prior to
     October 26, 2007, the Fund was not a party to an investment advisory
     agreement directly with any investment adviser and did not invest directly
     in portfolio securities. Instead, the Fund had invested all of its
     investable assets in the Standish Mellon Global Fixed Income Portfolio (the
     "Portfolio"), which was managed by Standish Mellon Asset Management Company
     LLC ("Standish Mellon" or the "Adviser"). The Portfolio had investment
     objectives, policies and limitations substantially identical to those of
     the Fund. The Fund's Board of Trustees determined annually whether the Fund
     should continue to invest in the Portfolio. The members of the Fund's Board
     of Trustees also serve as the Board of Trustees of the Portfolio. In that
     capacity, they considered annually whether to continue the investment
     advisory agreement between the Portfolio and Standish Mellon.

     In their most recent deliberations concerning their decision to approve the
     continuation of the investment advisory agreement, the Board of Trustees
     conducted the review and made the determinations that are described below.
     In conducting this review and in making such determinations, the
     Independent Trustees received from Standish Mellon a broad range of
     information in response to a written request prepared on their behalf by
     their own legal counsel. The Independent Trustees met alone in a private
     session with their legal counsel on September 27, 2007 to review these
     materials and to discuss the proposed continuation of the Portfolio's
     advisory agreement. Representatives of management attended a portion of the
     September meeting to provide an overview of the Adviser's organization,
     personnel, resources and strategic plans, and to respond to questions and
     comments arising from the Independent Trustees' review of the materials and
     their deliberations. The entire Board then met on October 30, 2007.

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

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

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

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

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

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

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

     Nature, Extent and Quality of Services

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

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

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

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

                   Mellon Institutional Funds Investment Trust
                    Standish Mellon Global Fixed Income Fund

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

     Investment Performance

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

     The Board considered the Fund's performance for the one-, three- and
     five-year periods ended July 31, 2007 based on the Lipper materials
     provided to the Board at the September 27, 2007 meeting. The Board found
     that the Fund underperformed its peer group average returns for the
     one-year period (4.97% vs. 5.29%), three-year period (4.58% vs. 4.85%) and
     five-year period (5.13% vs. 6.47%).

     Advisory Fee and Other Expenses

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

     The Portfolio's contractual advisory fee was 0.40%, which was in the 1st
     (best) quintile of its peer group of funds, the median fee of which was
     0.57%. The Portfolio's net management fee (after giving effect to expense
     limitations) was 0.266% (which included 0.025% of administrative services
     fees under Lipper's calculation methodology), below the peer group median
     net management fee of 0.469%. Based on the Lipper data, as well as other
     factors discussed at the September 27, 2007 meeting, the Board determined
     that the Portfolio's advisory fee is reasonable relative to its peer group
     averages.

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

     The Board also considered the Fund's (rather than solely the Portfolio's)
     expense ratio and compared it to that of its peer group of similar funds.
     The Board found that the actual net expense ratio of 0.648% (after giving
     affect to expense limitations) was lower than the median net expense ratio
     of the peer group of 0.906%, notwithstanding the fact that all of the other
     funds in the peer group were larger than the Portfolio.

     The Adviser's Profitability

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

     Economies of Scale

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

     Other Benefits

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

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

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

February 2008

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2007.

The financial markets experienced a major bout of volatility in 2007 stemming
from two principal sources: troubles in the credit markets related to the
difficulties experienced by mortgage securities backed by subprime loans, and
the high degree of leverage employed by many hedge funds, whose impact on the
markets has swollen significantly over the past decade. While the S&P 500 Index
managed to gain 3.5% in 2007 in a very volatile environment, it lost 3.8% in the
fourth quarter. The U.S. Federal Reserve Board was concerned with market
instability enough to lower rates three times in 2007 even as confidence in the
dollar reached new lows. In December, central banks coordinated their efforts to
provide liquidity facilities to institutions with impaired assets.

Credit markets responded to the subprime troubles with a broad-based flight to
quality as investors fled to short-term Treasury securities, resulting in a
significant steepening of the yield curve. In a dramatic repricing of risk,
spreads widened in the corporate bond sector compared to Treasury issues, which
has the effect of making corporate borrowing more expensive. In another
indication of just how disruptive this period was in the credit markets, even
some issuers of commercial paper - typically viewed as the safest segment of the
corporate market - had trouble issuing or rolling over their issues.

Liquidity has slowly returned to the bond markets in general, but it is still
less than normal. The financial and mortgage sectors clearly have been shaken,
and this will likely exacerbate the housing recession as banks become more
restrictive in their lending. In the view of some, the likelihood of a broader
U.S. recession has become greater; indeed, some economists maintain that we have
already entered one. Our view is that a period of diminished growth - around
1.5% to 2% GDP growth in 2008 vs. the 2.5% long-term trend - is more likely. We
see U.S. exports boosted by the weaker dollar, multi-year global economic
expansion and monetary growth, and reasonable corporate profitability -
especially for multinational franchises - as being positives that may partially
offset the drag of the housing sector and lower consumption. However, should the
"credit crunch" intensify - contrary to our expectations - the odds would favor
a full-scale recession.

We wish to thank you for your business and confidence in Mellon Institutional
Funds. Please feel free to contact us with questions or comments.

Sincerely,
J. David Officer
President

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

Global sovereign bonds provided solid returns in 2007 while most bonds with a
credit spread suffered. Despite the credit and liquidity crunch, global bonds
provided a year of risk adjusted returns very competitive with the Fund's
benchmark, the J.P. Morgan Non-U.S. Government Bond Index, which achieved a
total return of 5.06% during 2007. The international bond market continues to be
buffeted by concerns about structured credit, banking sector vulnerabilities,
and a potential U.S. recession. We continue to believe that the major central
banks in the U.S., Europe and the U.K. will need to cut rates further in 2008 as
the outlook for the U.S. economy continues to deteriorate due to a weaker
housing market and ongoing turmoil in the structured credit markets and banking
sector.

As we move into 2008, the market has also come to realize that the U.K. housing
market and economy will also likely be hurt significantly by tighter credit
conditions. The front end of the gilt yield curve rallied during the second half
of 2007 and the pound is weaker. The expected U.S. slowdown will, to some
extent, slow growth in Europe and Japan as well. Expectations for a global
decoupling from the U.S. are likely to be disappointed.

Weaker U.S. consumer demand and a depreciated U.S. currency, especially as
compared to the Euro, have reduced net exports for both Europe and Japan.
Furthermore, financial conditions have tightened in Europe as the result of the
credit and liquidity crunch.

However, emerging markets, led by China, India, Brazil, and Russia, continue to
do very well, as do other commodity exporting economies. Nevertheless, we
believe that the U.S. led downturn should take some of the shine off of these
regions' economic performance in 2008.

Performance

The Fund returned 4.35% in 2007, lagging its benchmark, but we believe it is
well positioned for better returns going forward if our "Outlook" below is
accurate. The Fund's underperformance relative to its benchmark in 2007 was
mainly driven by its exposure to the riskier parts of the global bond markets,
such as high yield and emerging market debt.

Even though we are disappointed that the Fund lost ground relative to its
benchmark, we are proud in that we restructured the portfolio in the first half
of 2007 and shed a lot of credit risk. The Fund has always invested heavily in
corporate credits and we avoided almost all of the blowups.

The Fund's main source of credit risk and underperformance has come from its
Northern Rock position. These securities were downgraded to high yield after we
purchased them at distressed levels when they were investment grade. We remain
optimistic, as to these holdings, however, as the restructuring and ownership
situation of the bank gets resolved. Unfortunately the process has taken much
longer than we had expected and so the mark-to-market impact on Fund performance
subtracted nearly 70 basis points.

The remaining drag on performance came from our other high yield exposure in
short dated high yield bonds, which we believe will mature at par, and some
other one-off exposures to emerging market debt.

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

On the positive side we had a great year in terms of our country, curve and
duration positioning for the Fund. The Fund consistently invested in the top
performing markets during 2007 which included Japan and Sweden during the first
half and then the U.K. and the U.S. during the second half of 2007.

The Fund was consistently long duration during 2007 which was not helpful during
the first half of 2007 but paid off when the credit crunch and flight to quality
occurred in the summer. We have been long duration in the U.S., Japan and the
U.K., while underweight duration in Europe. Even though U.S. bonds are not
represented in the benchmark index we thought the U.S. economy would lead the
international bond markets as the housing recession intensified.

Curve positioning was also helpful in 2007 as we anticipated a steeper yield
curve on the back of U.S. Federal Reserve rate cuts. We also benefited from a
flattening of the European yield curve even though the European Central Bank was
raising interest rates. The long end of the European yield curve is highly
correlated with that of the U.S. and was dragged lower as the global bond rally
intensified late in 2007.

Currency positioning also added about 20 basis points to the portfolio over the
course of 2007 as we held mostly short dollar positions against a wide variety
of currencies.

Outlook

We remain negative on the outlook for the U.S. economy as we believe the
continuing housing market correction will translate into a weaker consumer
sector. We believe that the unemployment rate will increase further over the
coming months, and that this will also slow consumer spending. We believe that a
weaker job market, combined with lower inflation and capacity utilization,
should prompt the Fed to cut rates below 3% in 2008. We are therefore positioned
for lower rates and a steeper yield curve in the U.S. We are also overweight
U.K. duration and have shorted the pound as we expect the British economy to
weaken. In Japan, we are overweight duration as we continue to expect that the
economic recovery will be very gradual. We remain underweight in Europe as
inflation has increasingly become a concern for the European Central Bank.
However, given the uncertain growth outlook, our base case is that rates remain
on hold for a while, so the underweight must be viewed in conjunction with the
U.S. and U.K. overweight positions. We believe growth in several of the smaller
developed economies, like Norway, Sweden, and Australia, will likely remain
relatively robust, and we remain underweight duration in these countries.

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

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

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (July 1, 2007 to December 31, 2007).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

                  Mellon Institutional Funds Investment Trust
                Standish Mellon International Fixed Income Fund

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


(1)  Organization and Significant Accounting Policies:

     Mellon Institutional Funds Investment Trust (the "Trust") is organized as a
     Massachusetts business trust and is registered under the Investment Company
     Act of 1940, as amended, as an open-end, management investment company.
     Standish Mellon 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, 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 registered investment companies ("RICs"), the Fund's net
     asset value ("NAV") will be calculated based upon the NAVs of such RICs.

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

     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 will then be valued at amortized cost based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized cost does not represent fair value.

     Reduced investor demand for mortgage loans and mortgage-related securities
     resulting from delinquencies and losses on residential mortgage loans
     (especially subprime and second-lien mortgage loans) and related market
     events have negatively impacted the performance and market value of certain
     mortgage-related investments and other fixed income securities, and
     increased investor yield requirements. This in turn has resulted in limited
     liquidity in the secondary market for such securities, adversely affecting
     the market value of mortgage-related securities and resulting in higher
     than usual volatility in the credit markets generally. It is possible that
     such limited liquidity in the secondary market for mortgage-related
     securities, and the related credit market volatility, could continue or
     worsen. To the extent that the market for securities in the Fund's
     portfolio becomes illiquid, the Fund might realize upon sale of an affected
     holding substantially less than the amount at which the Fund had previously
     been valuing the security in calculating its net asset value, and the Fund
     may incur substantial losses as a result.

     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.

                  Mellon Institutional Funds Investment Trust
                Standish Mellon International Fixed Income Fund

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

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

     C. Distributions to shareholders

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from capital gains, if any, after reduction of capital
     losses will be declared and distributed at least annually. Dividends from
     net investment income and distributions from capital gains, if any, are
     reinvested in additional shares of the Fund unless the shareholder elects
     to receive them in cash.

     Income and capital gain distributions are determined in accordance with
     income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in reclassifications, are primarily due to wash sales,
     post-October losses, capital loss carryovers, amortization of swap premium,
     timing of recognition of realized and unerealized appreciation and
     depreciation on futures contracts and differing treatments for foreign
     currency transactions.

     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 ("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 and other assets and liabilities initially expressed in
     foreign currencies are converted into U.S. dollars based upon current
     currency exchange rates. Purchases and sales of foreign investment
     securities and income and expenses are converted into U.S. dollars based
     upon currency exchange rates prevailing on the respective dates of such
     transactions.

     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.

     I. New Accounting Requirements

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

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

     The investment advisory fee paid to 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 $9,241, for the
     year ended December 31, 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 $122,042 for the
     year ended December 31, 2007.

     The Trust also entered into an agreement with Mellon Bank to perform
     certain securities lending activities and to act as the Fund's lending
     agent. Mellon Bank receives an agreed upon percentage of the net lending
     revenues. Pursuant to this agreement, the Fund was charged $5,483 for the
     year ended December 31, 2007. See Note 7 for further details.

     The Trust entered into two separate agreements with The Bank of New York
     that enables the Fund, and other funds in the Trust, to borrow, in the
     aggregate, (i) up to $35 million from a committed line of credit and (ii)
     up to $15 million from an uncommitted line of credit. Interest is charged
     to each participating fund based on its borrowings at a rate equal to the
     Federal Funds effective rate plus 1/2 of 1%. The participating funds also
     pay an annual fee, computed at a rate of 0.020 of 1% of the committed and
     uncommitted amounts and allocated ratably to the participating funds. In
     addition, a facility fee, computed at an annual rate of 0.060 of 1% on the
     committed amount, is allocated ratably among the participating funds at the
     end of each quarter. Pursuant to these agreements, the Fund was charged
     $4,280 for the year ended December 31, 2007, which amount is included in
     miscellaneous expenses on the statement of operations. See Note 9 for
     further details.

     The Trust reimburses BNY Mellon Asset Management for a portion of the
     salary of the Trust's Chief Compliance Officer. For the year ended December
     31, 2007, the Fund was charged $4,295, which amount is included in
     miscellaneous expenses in the statement of operations. No other director,
     officer or employee of Standish Mellon or its affiliates receives any
     compensation from the Trust or the Fund for serving as an officer or
     Trustee of the Trust. The Fund pays each Trustee who is not a director,
     officer or employee of Standish Mellon or its affiliates an annual fee and
     a per meeting fee as well as reimbursement for travel and out-of-pocket
     expenses. In addition, the Trust pays the legal fees for the independent
     counsel of the Trustees.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of BNY Mellon and an affiliate of Standish Mellon, to provide
     printing and fulfillment services for the Fund. Pursuant to this agreement,
     the Fund was charged $11,500, which amount is included in miscellaneous
     expenses in the statement of operations for the year ended December 31,
     2007.

     The Fund may pay administrative service fees. These fees are paid to
     affiliated or unaffiliated retirement plans, omnibus accounts and platform
     administrators and other entities ("Plan Administrators") that provide
     record keeping and/or other administrative support services to accounts,
     retirement plans and their participants. As compensation for such services,
     the Fund may pay each Plan Administrator an administrative service fee in
     an amount of up to 0.15% (on an annualized basis) of the Fund's average
     daily net assets attributable to Fund shares that are held in accounts
     serviced by such Plan Administrator. The Fund's adviser or its affiliates
     may pay additional compensation from their own resources to Plan
     Administrators and other entities for administrative services, as well as
     in consideration of marketing or other distribution-related services. These
     payments may provide an incentive for these entities to actively promote
     the Fund or cooperate with the distributor's promotional efforts. For the
     year ended December 31, 2007, the Fund was charged $693 for fees payable to
     BNY Mellon Wealth Management.

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

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

(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:

     Shares sold                                1,931,769              686,385

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


     At December 31, 2007, two shareholders of record, in the aggregate, held
     approximately 58.4% 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 fiscal years ended December 31, 2007 and December
     31, 2006, the Fund received redemption fees of $47 and $0, respectively.

(5)  Federal Taxes:

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

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

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2007 were as follows:


                                                             
        Cost for federal income tax purposes                    $98,127,056

     The tax character of distributions paid during the fiscal years ended
     December 31, 2007 and December 31, 2006, were as follows:

     At December 31, 2007, the Fund for federal income tax purposes, has capital
     loss carryovers which will reduce the Fund's taxable income arising from
     net realized gain on investments, if any, to the extent permitted by the
     Internal Revenue Code and thus will reduce the amount of distributions to
     shareholders which would otherwise be necessary to relieve the Fund of any
     liability for federal income tax. Such capital loss carryovers are as
     follows:



        Capital Loss
          Carry Over                            Expiration Date
        ------------                            ---------------
                                                
        $ 4,991,253                                12/31/2008
          4,991,253                                12/31/2009
          4,991,253                                12/31/2010
        -----------
        $14,973,759


     During 2007, the Fund utilized $235,158 in capital loss carryovers. At
     December 31, 2007, $7,578,424 of capital loss carryovers expired. The Fund
     also treated as expired $24,569,330 of capital losses due to limitations
     imposed by the Internal Revenue Service Code related to share ownership
     activity. It is uncertain whether the Fund will be able to realize the
     benefits of the remaining capital loss carryovers before they expire and
     utilization of the remaining capital loss carryovers could be subject to
     future limitations imposed by the Internal Revenue Code related to share
     ownership activity.

     The Fund elected to defer to its fiscal year ending December 31, 2008,
     $116,441 of capital losses during the period November 1, 2007 to December
     31, 2007.

(6)  Financial Instruments:

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

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

     Options

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

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

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

     At December 31, 2007, the Fund held a forward volatility option. 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 December 31, 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 are made or received by the Fund each
     day, depending on the daily fluctuations in the value of the underlying
     security, and are recorded for financial statement purposes as unrealized
     appreciation or depreciation by the Fund. There are several risks in
     connection with the use of futures contracts as a hedging device. The
     change in value of futures contracts primarily corresponds with the value
     of their underlying instruments or indices, which may not correlate with
     changes in the value of hedged investments. Buying futures tends to
     increase the Fund's exposure to the underlying instrument, while selling
     futures tends to decrease the Fund's exposure to the underlying instrument
     or hedge other investments. In addition, there is the risk that the Fund
     may not be able to enter into a closing transaction because of an illiquid
     secondary market. Losses may also arise if there is an illiquid secondary
     market or if the counterparty does not perform under the contract's terms.

     The Fund enters into financial futures transactions primarily to seek to
     manage its exposure to certain markets and to changes in securities prices
     and foreign currencies. Gains and losses are realized upon the expiration
     or closing of the futures contracts. Futures contracts are valued at the
     quoted daily settlement prices established by the exchange on which they
     trade.

     At December 31, 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 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 disagree as to the meaning of contractual terms in the agreements, and
     that there may be unfavorable changes in interest rates.

     At December 31, 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 year ended December 31, 2007 and
     earned interest on the invested collateral of $242,474 of which $229,732
     was rebated to borrowers or paid in fees. At December 31, 2007, the Fund
     did not have any securities out on loan. See also Note 10.

(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.

                Standish Mellon International Fixed Income Fund

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

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

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

     At December 31, 2007, the Fund had delayed delivery securities. See the
     Schedule of Investments for further details.

(9)  Line of Credit:

     On behalf of the Fund, and other funds in the Trust, the Trust has access
     to a credit facility, which enables each fund to borrow, in the aggregate,
     up to $35 million under a committed line of credit and up to $15 million
     under an uncommitted line of credit. During the year ended December 31,
     2007, the Fund had average borrowings outstanding of $932,160 for a total
     of twenty-five days and incurred $4,047 of interest expense. The Fund did
     not have an outstanding loan balance at December 31, 2007.

(10) Restatement:

     The Statement of Assets and Liabilities and Schedule of Investments have
     been restated to correct an error in the manner in which the Fund's
     securities lending agent and custodian accounted for the investment in
     pooled investment vehicles of cash collateral derived from the Fund's
     securities lending activity.

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

     The Fund determined that from December 11, 2007 through the December 31,
     2007 closing date of the financial statements of the Fund and continuing
     until March 10, 2008, the securities lending agent and custodian failed to
     account properly for the Fund's investments in the BlackRock Fund and the
     Dreyfus Fund. Specifically, the securities lending agent and custodian
     maintained, for each series of the Trust, subaccounts reflecting each
     series ownership of shares of the Dreyfus Fund and the BlackRock Fund which
     considered each such series to own a percentage of the Trust series'
     aggregate ownership of the Dreyfus Fund and the BlackRock Fund equal to
     each series' pro rata balance of the aggregate Trust cash collateral in the
     securities lending program, rather than according to each series' specific
     cash purchase and withdrawal activity in shares of the Dreyfus Fund and/or
     the BlackRock Fund. The management of the Trust determined that the
     securities lending agent and custodian should have accounted for these
     investments on a Fund specific basis in accordance with actual cash
     purchases and withdrawals. This erroneous methodology caused differences in
     the entries in the Fund's books and records on which the Fund's Schedule of
     Investments and Statement of Assets and Liabilities are based. These
     financial statements have been restated accordingly. (The Fund's annual
     report for the fiscal year ended December 31, 2007 containing these
     financial statements was previously posted on the Trust's website but had
     not been mailed to shareholders or filed with the Commission.) The
     liability listed as "Payable for securities lending collateral investment"
     represents the extent to which the Fund's cash needs to repay collateral
     exceeded the value of its interest in the Dreyfus Fund. The erroneous
     sub-accounting methodology had no effect on the computation of the Fund's
     net asset value.

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

     Effective March 10, 2008, the accounting for cash collateral investments in
     pooled vehicles was corrected to account for specific purchases and
     redemptions of interests in such vehicles by the Fund. All activity was
     reprocessed to reflect correct ownership by the Fund in each vehicle and
     the above described financial statements restated accordingly.

     The amounts as originally reported and as restated are as follows:

                  Mellon Institutional Funds Investment Trust
                Standish Mellon International Fixed Income Fund

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

To the Trustees of Mellon Institutional Funds Investment Trust and Shareholders
of Standish Mellon International Fixed Income Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights, after the restatement
described in Note 10 to the financial statements, present fairly, in all
material respects, the financial position of Standish Mellon International Fixed
Income Fund (the "Fund") at December 31, 2007, the results of its operations for
the year then ended, the changes in its net assets for each of the two years in
the period then ended and the financial highlights for each of the five years in
the period then ended, in conformity with accounting principles generally
accepted in the United States of America. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 2007 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

                  Mellon Institutional Funds Investment Trust
                Standish Mellon International Fixed Income Fund

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

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

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

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

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

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

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

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

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

Nature, Extent and Quality of Services

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

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

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

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

Investment Performance

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

                  Mellon Institutional Funds Investment Trust
                Standish Mellon International Fixed Income Fund

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

The Board considered the Fund's performance for the one-, three- and five-year
periods ended July 31, 2007 based on the Lipper materials provided to the Board
at the September 27, 2007 meeting. The Board found that the Fund outperformed
its peer group average return for the one-year period (4.76% vs. 4.37%), but
underperformed its peer group average returns for the three-year period (4.63%
vs. 4.68%) and five-year period (4.87% vs. 6.42%).

Advisory Fee and Other Expenses

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

The Fund's contractual advisory fee was 0.40%, which was in the 1st (best)
quintile of its peer group of funds, the median fee of which was 0.535%. The
Fund's net management fee was 0.414% (which included 0.014% in administrative
services fees under Lipper's calculation methodology), below the peer group
median net management fee of 0.471%. Based on the Lipper data, as well as other
factors discussed at the September 27, 2007 meeting, the Board determined that
the Fund's advisory fee is reasonable relative to its peer group averages.

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

The Board also considered the Fund's expense ratio and compared it to that of
its peer group of similar funds. The Board found that the actual net expense
ratio of 0.676% was lower than the median net expense ratio of the peer group of
0.76%, notwithstanding the fact that most of the other funds in the peer group
were larger than the Fund.

The Adviser's Profitability

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

Economies of Scale

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

Other Benefits

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

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

                                     * * *

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

         As of December 31, 2007, the Registrant has adopted a Code of Ethics,
         as defined in Item 2(b) of Form N-CSR, that applies to the Principal
         Executive Officer and Principal Financial Officer. For the fiscal year
         ended December 31, 2007, there were no substantive amendments to a
         provision of the Code of Ethics nor were there any waivers granted from
         a provision of the Code of Ethics. A copy of the Registrant's Code of
         Ethics that applies to the Principal Executive Officer and Principal
         Financial Officer is filed as an exhibit to this Form N-CSR under Item
         12(a)(1).

Item 3.  Audit Committee Financial Expert.

         The Registrant's Board of Trustees has determined that the Registrant
         has more than one audit committee financial expert, as defined in Item
         3 of Form N-CSR, serving on its audit committee. The audit committee
         financial experts serving on the Registrant's audit committee are John
         H. Hewitt and Caleb Loring III, both of whom are "independent" pursuant
         to paragraph (a)(2) of Item 3 of Form N-CSR. Mr. Hewitt served at
         Morgan Stanley as a securities analyst and also in a supervisory role
         regarding analysis. He has held a chartered financial analyst
         designation, as well as a master's degree in business administration
         from Harvard University. He has been a member of the Registrant's audit
         committee since its inception. Mr. Loring served as an executive in the
         commercial lending division of the Bank of Boston, N.A., performing and
         supervising credit analyses and reviewing financial statements of
         potential and existing borrowers. Also, Mr. Loring has served as a
         private trustee in the Ayer Family Office, where his duties involve
         financial statement analysis. He has been a member of the Registrant's
         audit committee since its inception, and has served on the audit
         committees of several privately held companies.

Item 4.  Principal Accountant Fees and Services.

         (a)  AUDIT FEES: The aggregate fees billed for professional services
              rendered by the principal accountant, PricewaterhouseCoopers LLP,
              for the audit of the Registrant's annual financial statements or
              services that are normally provided by the accountant in
              connection with statutory and regulatory filings for the fiscal
              years ended December 31, 2007 and 2006 were $576,940 and $741,015,
              respectively.
         (b)  AUDIT RELATED FEES: The aggregate fees billed for the fiscal years
              ended December 31, 2007 and 2006 for assurance and related
              services by PricewaterhouseCoopers LLP that are reasonably related
              to the performance of the audit of the Registrant's financial
              statements and are not reported under paragraph (a) of this Item
              were $61,950 and $61,000, respectively. The nature of the services
              comprising the fees disclosed under this Item for both years
              included: the examination of compliance with requirements of Rule
              17f-2 of the Investment Company Act of 1940.
         (c)  TAX FEES: The aggregate fees billed for the fiscal years ended
              December 31, 2007 and 2006 for professional services rendered by
              PricewaterhouseCoopers LLP for tax compliance, tax advice, and tax
              planning were $155,690 and $260,010, respectively. Services
              rendered in both years included asset diversification testing, the
              preparation of tax returns and extensions, the review of periodic
              distributions.
         (d)  ALL OTHER FEES: No such fees were billed to the Registrant by
              PricewaterhouseCoopers LLP for 2007 or 2006.
         (e)  (1) AUDIT COMMITTEE PRE-APPROVAL POLICY: The Registrant's audit
              committee pre-approves all audit and non-audit services to be
              performed by the Registrant's accountant before the accountant is
              engaged by the Registrant to perform such services.
         (e)  (2) 100% of the services described in each of paragraphs (b)
              through (d) of this Item 4 were pre-approved by the Registrant's
              audit committee before the accountant was engaged by the
              Registrant to perform such services.
         (f)  Not applicable.


         (g)  The aggregate non-audit fees billed by PricewaterhouseCoopers LLP
              for services rendered to the Registrant and the Registrant's
              investment advisers, and any entity controlling, controlled by or
              under common control with the advisers that provides ongoing
              services to the Registrant for the fiscal years ended December
              31, 2007 and 2006 were $0 and $0, respectively. The aggregate
              non-audit fees billed by the Registrant's accountant for services
              rendered to the Registrant's transfer agent by
              PricewaterhouseCoopers LLP for the fiscal years ended December
              31, 2007 and 2006 were $98,628 and $105,570, respectively.
              Services provided in both years included a review of the transfer
              agency function and to issue a report under Rule 17Ad-13(a)(3) of
              the Securities and Exchange Act of 1934.
         (h)  Because all of the non-audit services rendered to the
              Registrant's investment adviser or any entity controlling,
              controlled by, or under common control with the investment
              adviser that provides ongoing services to the registrant were
              pre-approved by the Registrant's Audit Committee of the Board of
              Trustees and no such non-audit services were not pre-approved,
              the Audit Committee was not asked to consider whether the
              provision of non-audit services rendered to the Registrant's
              investment adviser or any entity controlling, controlled by, or
              under common control with the investment adviser that provides
              ongoing services to the registrant which were not pre-approved by
              the Registrant's Audit Committee is compatible with maintaining
              the principal accountant's independence.

Item 5.  Audit Committee of Listed Registrants.

         Not applicable to the Registrant.

Item 6.  Schedule of Investments

         Included as part of the report to shareholders filed under Item 1 of
         this Form N-CSR.

Item 7.  Disclosure  of  Proxy  Voting  Policies  and  Procedures  for
         Closed-End  Management  Investment Companies.

         Not applicable to the Registrant.

Item 8.  Portfolio Managers of Closed-End Management Investment Companies

         Not applicable to the Registrant.

Item 9.  Purchases of Equity  Securities  by  Closed-End  Management
         Investment Company and  Affiliated Purchasers.

         Not applicable to the Registrant.

Item 10. Submission of Matters to a Vote of Security Holders.

         There have been no material changes.

Item 11. Controls and Procedures.

         (a) The Chief Executive and Financial Officers concluded that the
         Registrant's Disclosure Controls and Procedures are effective based on
         the evaluation of the Disclosure Controls and Procedures as of a date
         within 90 days of the filing date of this report.

         These officers have determined, however, that as of and prior to
         December 31, 2007 and continuing until March 10, 2008, the Registrant
         had a significant deficiency in its internal control over financial
         reporting related to the accounting for the investment of cash
         collateral derived from securities lending activities in interests in
         cash collateral pooled investment vehicles. Since December 31, 2007,
         but prior to the date of this filing, management has revised its
         internal control over financial


         reporting to improve the effectiveness of the controls to ensure that
         the investment in pooled investment vehicles of cash collateral
         derived from securities lending activities is accounted for properly.
         As a result of this deficiency, the statements of assets and
         liabilities, including the schedules of investments as of December 31,
         2007, of the Standish Mellon Fixed Income Fund, Standish Mellon Global
         Fixed Income Fund and Standish Mellon International Fixed Income Fund
         (the "Funds") were restated from those initially posted to the Funds'
         website but not yet mailed to shareholders or filed with the
         Commission in any previous Form N-CSR, in order to appropriately
         account for such investments. However, there was no impact to the net
         asset value of these Funds' shares for the report period.

         (b) There have been no changes in the Registrant's internal control
         over financial reporting that occurred during the Registrant's second
         fiscal quarter covered by this report that have materially affected, or
         are reasonably likely to materially affect, the Registrant's internal
         control over financial reporting. However, as discussed above,
         subsequent to December 31, 2007, the Registrant's internal control over
         financial reporting was enhanced.
