February 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2006.

Financial markets showed substantial resilience in 2006, shrugging off concerns
that the slowdown in the housing market could drag the rest of the economy into
recession. The U.S. Federal Reserve (Fed) paused in its tightening cycle in
August, after 17 rate hikes since June 2004, as the Fed became convinced that
inflationary forces, and expectations, were under control. Perhaps the most
notable feature of this cycle is that the housing bubble is bursting at a time
when rates are not high. In previous cycles, housing market declines typically
follow a period of Fed tightenings that drive rates to extreme levels, choking
off credit, including mortgage financing. In this environment, credit for
housing and other sectors remains plentiful, with the housing pullback largely a
function of prices soaring beyond affordable levels for many prospective buyers.

The stock market climbed the proverbial "wall of worry" during 2006, with the
S&P 500 hitting new highs and providing a gain of 15.8%, including an 8.8%
advance in the fourth quarter. With U.S. monetary policy moderating, energy
prices in a swoon and the inflation threat receding, investors clearly feel that
the case for a soft landing is being reinforced.

In the bond markets, short-term rates advanced steadily, for the most part, in
cadence with the Fed's rate increases, with the 6-month Treasury bill ending the
year at 4.9%, up about 70 basis points. Rates on longer-term bonds increased to
a lesser degree, with the 10-year Treasury note ending about 30 basis points
higher at 4.7%. This produced an inverted yield curve, which is often a leading
indicator of recession.

Going forward, there is still much debate over the impact of the housing
downturn on the overall economy. We believe that the housing market is in for
prolonged weakness, because rates are already at relatively modest levels. Thus,
the boost provided by lower mortgage rates in the future is likely to be smaller
for housing than in it has been in previous cycles. However, there are other
bullish factors that should mitigate the drag of the housing market. As noted,
liquidity remains plentiful, and corporations are flush with cash. Spreads of
high yield bonds above Treasuries remain tight - an indicator that credit is
still available for riskier borrowers. High yield spreads tend to widen when the
market perceives a recession is likely.

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,

/s/ Patrick J. Sheppard

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

With solid economic growth and rising inflation during the first half of 2006,
the U.S. Federal Reserve (Fed) raised the federal funds rate 100 basis points to
5.25% between December 13, 2005 to June 29, 2006. By mid-year, significant
deterioration in the U.S. housing market and related slowdown in growth pushed
the Fed to pause in its rate hike cycle, and for the remainder of the year, the
Fed left the federal funds rate unchanged. While measures of inflation and
growth declined modestly during the second half of the year, the employment
picture was strong. With low unemployment and solid job gains, the Fed is
concerned that tightness in the labor market will result in higher wages and
rising inflation. While their inflation outlook remains hawkish, the Fed's view
on growth has softened due primarily to weakness in the U.S. housing market.
With continued high inventories of unsold homes, the slowdown in U.S. housing
activity continues to pose a significant risk for the economy into 2007. In this
mixed economic environment, 10-year Treasury yields have ranged between 4.5% and
5.25%, closing the year at 4.70%. The yield curve flattened with both 2- and
30-year Treasuries yielding 4.80% at year-end.

For 2006, the Standish Mellon Fixed Income Fund (Fund) returned 4.38% compared
to 4.33% for the Fund's benchmark, the Lehman Brothers U.S. Aggregate Index.
Various sectors outperformed Treasuries, with below investment grade and
emerging market bonds posting the strongest returns for the period. Amid low
volatility, the environment for spreads across sectors has remained favorable.
The Fund's allocation to high yield, emerging market and BBB-rated corporate
bonds have contributed positively to performance. The portfolio's position in
Treasury Inflation Protected Securities (TIPS) detracted from returns as
negative inflation accruals resulted in underperformance as compared to nominal
Treasuries. With the outperformance of high quality sectors, the underweight
position of the Fund in mortgages was also a slight negative. The Fund's
exposure to international bonds, both hedged and unhedged, benefited returns as
a result of their yield advantage relative to domestic bonds.

As we begin the new year, we expect the Fed will leave the federal funds rate
unchanged as it waits to see if moderating growth brings inflation down to a
rate of approximately 2%. The risks to this view include inflationary pressures
arising from a strong labor market or weaker growth due to further declines in
housing activity. As the interplay between growth and inflation keeps the Fed on
hold, we expect an environment of low volatility and a flat yield curve to
persist over the short term. However, with the possibility of the Fed lowering
the federal funds rate and a steeper yield curve, we continue to position the
Fund to remain underweight the long end in favor of intermediate bonds.

The portfolio is well positioned to take advantage of this environment. We have
increased the Fund's allocation to mortgages in order to capitalize on low
volatility and favorable supply and demand conditions. We are likely to reduce
the Fund's position in TIPS, as declining oil prices and a slowing economy are
unlikely to result in higher inflation expectations. We see incremental
opportunities to add international bonds in order to take advantage of the
hedged yield advantage of some countries relative to the U.S., including Japan,
Poland and Sweden.

As always, we look forward to serving you in 2007.

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, 2006 to December 31, 2006).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

                                                                 Expenses Paid

Hypothetical (5% return
  per year before expenses)    $1,000.00        $1,022.68            $2.55

- ----------
+     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.

                   Mellon Institutional Funds Investment Trust
                       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 object of the Fund is primarily to achieve a high level of current
      income, consistent with conserving principal and liquidity, and
      secondarily to seek capital appreciation when changes in interest rates
      and economic conditions indicate that capital appreciation may be
      available without significant risk to principal. The Fund invests all of
      its investable assets in an interest of Standish Mellon Fixed Income
      Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds
      Master Portfolio (the "Portfolio Trust"), which is organized as a New York
      trust and has the same investment objective as the Fund. The Portfolio
      seeks to achieve its objective by investing, under normal circumstances,
      at least 80% of net assets in fixed income securities issued by U.S. and
      foreign governments and companies. The value of the Fund's investment in
      the Portfolio reflects the Fund's proportionate interest in the net assets
      of the Portfolio (100% at December 31, 2006). The performance of the Fund
      is directly affected by the performance of the Portfolio. The financial
      statements of the Portfolio are included elsewhere in this report and
      should be read in conjunction with the Fund's financial statements.

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

      A. Investment security valuations

      Fund shares are valued as of the close of regular trading (normally 4:00
      p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
      is open. The Fund records its investment in the Portfolio at value. The
      Portfolio values its securities at value as discussed in Note 1A of the
      Portfolio's Notes to Financial Statements, which are included elsewhere in
      this report.

      B. Securities transactions and income

      The Fund's investment in the Portfolio is recorded on settlement date. The
      Portfolio's securities transactions are recorded as of the trade date as
      discussed in Note 1B of the Portfolio's Notes to Financial Statements,
      which are included elsewhere in this report. Currently, the Fund's net
      investment income consists of the Fund's pro rata share of the net
      investment income of the Portfolio, less all expenses of the Fund
      determined in accordance with accounting principles generally accepted in
      the United States of America. All realized and unrealized gains and losses
      of the Fund represent pro rata shares of gains and losses of the
      Portfolio.

      C. Distributions to shareholders

      Distributions to shareholders are recorded on the ex-dividend date. The
      Fund's distributions from capital gains, if any, after reduction of
      capital losses are declared and distributed at least annually. In
      determining the amounts of its dividends, the Fund will take into account
      its share of the income, gains or losses, expenses, and any other tax
      items of the Portfolio. Dividends from net investment income and
      distributions from capital gains, if any, are reinvested in additional
      shares of the Fund unless a shareholder elects to receive them in cash.

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

      Permanent book and tax basis differences relating to shareholder
      distributions will result in reclassifications among undistributed net
      investment income(loss), accumulated net realized gain (loss) and paid in
      capital. Undistributed net investment income (loss) and accumulated net
      realized gain (loss) on investments may include temporary book and tax
      basis differences which will reverse in a subsequent period. Any taxable
      income or gain remaining at fiscal year end is distributed in the
      following year.

      D. Expenses

      The majority of expenses of the Trust or Portfolio Trust are directly
      identifiable to an individual fund or portfolio. Expenses which are not
      readily identifiable to a specific fund or portfolio are allocated among
      funds of the Trust and/or portfolios of the Portfolio Trust taking into
      consideration, among other things, the nature and type of expense and the
      relative size of the funds or portfolios.

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

      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. Federal Income 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.

      G. New Accounting Requirements

      In July 2006, the Financial Accounting Standards Board issued
      Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
      Interpretation of FASB Statement No. 109" (the "Interpretation"). The
      Interpretation establishes for all entities, including pass-through
      entities such as the Portfolio, a minimum threshold for financial
      statement recognition of the benefit of positions taken in filing tax
      returns (including whether an entity is taxable in a particular
      jurisdiction), and requires certain expanded tax disclosures. Adoption of
      FIN 48 is required for fiscal years beginning after December 15, 2006 and
      is to be applied to all open tax years as of the effective date. At this
      time, management is evaluating the implications of FIN 48 and its impact,
      if any, in the financial statements has not yet been determined.

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

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

      The Fund does not directly pay any investment advisory fees, but
      indirectly bears its pro rata share of the compensation paid by the
      Portfolio to Standish Mellon Asset Management Company LLC ("Standish
      Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, for
      such services. See Note 2 of the Portfolio's Notes to Financial Statements
      which are included elsewhere in this report. Standish Mellon voluntarily
      agreed to limit the total operating expenses of the Fund and its pro rata
      share of the Portfolio expenses (excluding brokerage commissions, taxes
      and extraordinary expenses) to 0.50% of the Fund's average daily net
      assets.

      On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
      New York Company, Inc. ("BNY") announced that they had entered into a
      definitive agreement to merge. The new company will be called The Bank of
      New York Mellon Corporation. As part of this transaction, Standish Mellon
      would become an indirect wholly-owned subsidiary of The Bank of New York
      Mellon Corporation. The transaction is subject to certain regulatory
      approvals and the approval of BNY's and MFC's shareholders, as well as
      other customary conditions to closing. Subject to such approvals and the
      satisfaction of the other conditions, MFC and BNY expect the transaction
      to be completed in the third quarter of 2007.

      The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly
      owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of
      Mellon Financial Corporation and an affiliate of Standish Mellon, to
      provide personnel and facilities to perform transfer agency and certain
      shareholder services for the Fund. For these services, the Fund pays
      Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based
      fees, as well as, out-of-pocket expenses. Pursuant to this agreement the
      Fund was charged $19,295, for the year ended December 31, 2006.

      The Trust has contracted Mellon Investor Services LLC, a wholly owned
      subsidiary of Mellon Financial Corporation and an affiliate of Standish
      Mellon, to provide printing and fulfillment services for the Fund.
      Pursuant to this agreement, the Fund was charged $4,850 for the year ended
      December 31, 2006.

      The Trust reimburses Mellon Asset Management for a portion of the salary
      of the Trust's Chief Compliance Officer. For the year ended December 31,
      2006, the Fund was charged $4,000. No other director, officer or employee
      of Standish Mellon or its affiliates receives any compensation from the
      Trust or the Portfolio Trust for serving as an officer or Trustee of the
      Trust. The Fund pays each Trustee who is not a director, officer or

      The Fund pays administrative service fees. These fees are paid to
      affiliated or unaffiliated retirement plans, omnibus accounts and platform
      administrators and other entities ("Plan Administrators") that provide
      record keeping and/or other administrative support services to accounts,
      retirement plans and their participants. As compensation for such
      services, the Fund may pay each Plan Administrator an administrative
      service fee in an amount of up to 0.15% (on an annualized basis) of the
      Fund's average daily net assets attributable to Fund shares that are held
      in accounts serviced by such Plan Administrator. The Fund's adviser or its
      affiliates may pay additional compensation from their own resources to
      Plan Administrators and other entities for administrative services, as
      well as in consideration of marketing or other distribution-related
      services. These payments may provide an incentive for these entities to
      actively promote the Fund or cooperate with the distributor's promotional
      efforts. For the year ended December 31, 2006, the Fund was charged
      $161,161 for fees payable to Mellon Private Wealth Management.

      year ended December 31, 2006, aggregated $186,365,938 and $109,974,249,
      respectively. The Fund receives a proportionate share of the Portfolio's
      income, expenses, and realized and unrealized gains and losses based on
      applicable tax allocation rules.

(4)   Shares of Beneficial Interest:

      The Declaration of Trust permits the Trustees to issue an unlimited number

      At December 31, 2006, two shareholders of record held in the aggregate
      approximately 21% 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 year ended December 31, 2006, the
      Fund received $4,451 in redemption fees.

      At December 31, 2006, 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:

      It is uncertain whether the Fund will be able to realize the benefits of
      the losses before they expire.

      The Fund elected to defer to its fiscal year ending December 31, 2007,
      $252,518 of capital losses and $227,501 of currency losses recognized
      during the period November 1, 2006 to December 31, 2006.

             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 and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Standish Mellon Fixed Income Fund (the "Fund") at December 31, 2006, 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 agreement of the amount of the investment in the Standish
Mellon Fixed Income Portfolio (the "Portfolio") at December 31, 2006 to the
Portfolio's records, provide a reasonable basis for our opinion.

                   Mellon Institutional Funds Master Portfolio
                     Standish Mellon Fixed Income Portfolio

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

(1)   Organization and Significant Accounting Policies:

      Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
      organized as a master trust fund under the laws of the State of New York
      on January 18, 1996 and is registered under the Investment Company Act of
      1940, as amended, as an open-end, management investment company. Standish
      Mellon Fixed Income Portfolio (the "Portfolio") is a separate diversified
      investment series of the Portfolio Trust.

      The objective of the Portfolio is to achieve a high level of current
      income, consistent with conserving principal and liquidity, and
      secondarily to seek capital appreciation when changes in interest rates
      and economic conditions indicate that capital appreciation may be
      available without significant risk to principal by investing, under normal
      circumstances, at least 80% of net assets in fixed income securities
      issued by U.S. and foreign governments and companies.

      At December 31, 2006 there was one fund, Standish Mellon Fixed Income Fund
      (the "Fund"), invested in the Portfolio. The value of the Fund's
      investment in the Portfolio reflects the Fund's proportionate interest in
      the net assets of the Portfolio. The Fund's proportionate interest at
      December 31, 2006 was 100%.

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

      A. Investment security valuations

      Securities are valued at the last sale prices on the exchange or national
      securities market on which they are primarily traded. Securities not
      listed on an exchange or national securities market, or securities for
      which there were no reported transactions, are valued at the last quoted
      bid price. Securities that are fixed income securities, other than
      short-term instruments with less than sixty days remaining to maturity,
      for which accurate market prices are readily available, are valued at
      their current market value on the basis of quotations, which may be
      furnished by a pricing service or dealers in such securities. Securities
      (including illiquid securities) for which quotations are not readily
      available are valued at their fair value as determined in good faith under
      consistently applied procedures under the general supervision of the
      Trustees.

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

      Short-term instruments with less than sixty days remaining to maturity are
      valued at amortized cost, which approximates market value. If the
      Portfolio acquires a short-term instrument with more than sixty days
      remaining to its maturity, it is valued at current market value until the
      sixtieth day prior to maturity and then is valued at amortized cost based
      upon the value on such date unless the Trustees determine during such
      sixty-day period that amortized cost does not represent fair value.

      B. Securities transactions and income

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

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

      C. Income taxes

      The Portfolio is treated as a disregarded entity for federal tax purposes.
      No provision is made by the Portfolio for federal or state income taxes on
      any taxable income of the Portfolio because each investor in the Portfolio
      is ultimately responsible for the payment of any taxes. Since the
      Portfolio's investor is a regulated investment company that invests all or
      substantially all of its assets in the Portfolio, the Portfolio normally
      must satisfy the source of income and diversification requirements
      applicable to regulated investment companies (under the Internal Revenue
      Code) in order for its investors to satisfy them.

                                       35



                   Mellon Institutional Funds Master Portfolio
                     Standish Mellon Fixed Income Portfolio

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

      Section 988 of the Internal Revenue Code provides that gains or losses on
      certain transactions attributable to fluctuations in foreign currency
      exchange rates must be treated as ordinary income or loss. For financial
      statement purposes, such amounts are included in net realized gains or
      losses.

      D. Foreign currency transactions

      The Portfolio maintains its books and records in U.S. dollars. Investment
      security valuations, other assets, and liabilities initially expressed in
      foreign currencies are converted into U.S. dollars based upon current
      currency exchange rates. Purchases and sales of foreign investment
      securities and income and expenses are converted into U.S. dollars based
      upon currency exchange rates prevailing on the respective dates of such
      transactions.

      E. Foreign Investment risk

      There are certain additional risks involved in investing in foreign
      securities that are not inherent in investments in domestic securities.
      These risks may involve adverse political and economic developments,
      including the possible imposition of capital controls or other foreign
      governmental laws or restrictions. In addition, the securities of some
      foreign companies and securities markets are less liquid and at times may
      be more volatile than securities of comparable U.S. companies and U.S.
      securities markets. The risks described above apply to an even greater
      extent to investments in emerging markets. The securities markets of
      emerging countries are generally smaller, less developed, less liquid, and
      more volatile than the securities markets of the U.S. and developed
      foreign markets.

      F. Commitments and contingencies

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

      G. Expenses

      The majority of expenses of the Trust or Portfolio Trust are directly
      identifiable to an individual fund or portfolio. Expenses which are not
      readily identifiable to a specific fund or portfolio are allocated among
      funds of the Trust or portfolios of the Portfolio Trust taking into
      consideration, among other things, the nature and type of expense and the
      relative size of the funds or portfolios.

      H. Affiliated issuers

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

      I. New Accounting Requirements

      In July 2006, the Financial Accounting Standards Board issued
      Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
      Interpretation of FASB Statement No. 109" (the "Interpretation"). The
      Interpretation establishes for all entities, including pass-through
      entities such as the Portfolio, a minimum threshold for financial
      statement recognition of the benefit of positions taken in filing tax
      returns (including whether an entity is taxable in a particular
      jurisdiction), and requires certain expanded tax disclosures. Adoption of
      FIN 48 is required for fiscal years beginning after December 15, 2006 and
      is to be applied to all open tax years as of the effective date. At this
      time, management is evaluating the implications of FIN 48 and its impact,
      if any, in the financial statements has not yet been determined.

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

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

      The investment advisory fee paid to Standish Mellon for overall investment
      advisory administrative services, and general office facilities is paid
      monthly at the annual rate of 0.40% of the Portfolio's first $250,000,000
      of average daily net assets, 0.35% of the next $250,000,000 of average
      daily net assets, and 0.30% of the average daily net assets in excess of
      $500,000,000.

      On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
      New York Company, Inc. ("BNY") announced that they had entered into a
      definitive agreement to merge. The new company will be called The Bank of
      New York Mellon Corporation. As part of this transaction, Standish Mellon
      would become an indirect wholly-owned subsidiary of The Bank of New York
      Mellon Corporation. The transaction is subject to certain regulatory
      approvals and the approval of BNY's and MFC's shareholders, as well as
      other customary conditions to closing. Subject to such approvals and the
      satisfaction of the other conditions, MFC and BNY expect the transaction
      to be completed in the third quarter of 2007.

      The Portfolio Trust has entered into an agreement with Mellon Bank, N.A.
      ("Mellon Bank"), a wholly owned subsidiary of Mellon Financial Corporation
      and an affiliate of Standish Mellon, to provide custody, administration
      and fund accounting services for the Portfolio. For these services the
      Portfolio pays Mellon Bank a fixed fee plus asset and transaction based
      fees, as well as out-of-pocket expenses. Pursuant to this agreement the
      Portfolio was charged $192,723 during the year ended December 31, 2006.

      The Portfolio Trust also entered into an agreement with Mellon Bank to
      perform certain securities lending activities and to act as the
      Portfolio's lending agent. Mellon Bank receives an agreed upon percentage
      of the net lending revenues. Pursuant to this agreement, Mellon Bank
      earned $23,586 for the year ended December 31, 2006. See Note 6 for
      further details.

      The Trust reimburses Mellon Asset Management for a portion of the salary
      of the Trust's and Portfolio Trust's Chief Compliance Officer. No other
      director, officer or employee of Standish Mellon or its affiliates
      received any compensation from the Trust or the Portfolio Trust for
      serving as an officer or Trustee of the Trust or the Portfolio Trust. The
      Fund and Portfolio Trust pays each Trustee who is not a director, officer
      or employee of Standish Mellon or its affiliates (the "Independent
      Trustees") an annual fee and the Portfolio Trust pays each Independent
      Trustee a per meeting fee as well as reimbursement for travel and out of
      pocket expenses. In addition, the Portfolio Trust pays the legal fees for
      the counsel to the Independent Trustees.

(3)   Purchases and Sales of Investments:

      Purchases and proceeds from sales of investments, other than short-term
      obligations, for the year ended December 31, 2006 were as follows:

(4)   Federal Taxes:

      The cost and unrealized appreciation (depreciation) in value of the
      investment securities owned at December 31, 2006, as computed on a federal
      income tax basis, were as follows:

      Cost for federal income tax purposes               $   823,742,767

(5)   Financial Instruments:

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

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

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

      Options

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

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

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

      For the year ended December 31, 2006, the Portfolio entered into the
      following transactions:

                                                 Number of

      At December 31, 2006, the Portfolio had no written options outstanding.

      Forward currency exchange contracts

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

      At December 31, 2006, the Portfolio held forward currency exchange
      contracts. See Schedule of Investments for further details.

      Futures contracts

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

      At December 31, 2006, the Portfolio held open financial futures contracts.
      See the Schedule of Investments for further details.

      Swap agreements

      The Portfolio may enter into swap agreements. A swap is an agreement to
      exchange the return generated by one instrument for the return generated
      by another instrument. The Portfolio may enter into interest rate, credit
      default and total return swap agreements to manage its exposure to
      interest rates and credit risk. Interest rate swap agreements involve the
      exchange by the Portfolio with another party of their respective
      commitments to pay or receive interest, e.g., an exchange of floating rate
      payments for fixed rate payments with respect to a notional amount of
      principal. In a credit default swap, one party makes a stream of payments
      to another party in exchange for the right to receive a specified return
      in the event of a default by a third party on its obligation. The
      Portfolio may use credit default swaps to provide a measure of protection
      against defaults of issuers (i.e., to reduce risk where the Portfolio owns
      or has exposure to the corporate or sovereign issuer) or to take an active
      long or short position with respect to the likelihood of a particular
      corporate or sovereign issuer's default. Total return swap agreements
      involve commitments to pay interest in exchange for a market-linked
      return, both based on notional amounts. To the extent the total return of
      the security or index underlying the transaction exceeds or falls short of
      the offsetting interest rate obligation, the portfolio will receive a
      payment from or make a payment to the counterparty. In connection with
      these agreements, cash or securities may be set aside as collateral in
      accordance with the terms of the swap agreement. The Portfolio earns
      interest on cash set aside as collateral. Swaps are marked to market daily
      based upon quotations, which may be furnished by a pricing service or
      dealers in such securities and the change in value, if any, is recorded as
      unrealized appreciation or depreciation in the Statement of Operations.
      These financial instruments are not actively traded on financial markets.
      The values assigned to these instruments are based upon the best available
      information and because of the uncertainty of the valuation, these values
      may differ significantly from the values that would have been realized had
      a ready market for these instruments existed, and differences could be
      material. Payments received or made at the beginning of the measurement
      period are reflected as such on the Statement of Assets and Liabilities.
      Payments received or made from credit default swaps at the end of the
      measurement period are recorded as realized gain or loss in the Statement
      of Operations. Net payments of interest on interest rate swap agreements,
      if any, are included as part of realized gain and loss. Entering into
      these agreements involves, to varying degrees, elements of credit, market,
      and documentation risk in excess of the amounts recognized in the
      Statement of Assets and Liabilities. Such risks involve the possibility
      that there will be no liquid market for these agreements, that the
      counterparty to the agreements may default on its obligation to perform or
      disagree as to the meaning of contractual terms in the agreements, and
      that there may be unfavorable changes in interest rates.

      At December 31, 2006, the Portfolio held open swap agreements. See the
      Schedule of Investments for further details.

(6)   Security Lending:

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

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

      The Portfolio loaned securities during the year ended December 31, 2006
      and earned interest on the invested collateral of $3,638,399 of which,
      $3,582,897 was rebated to borrowers or paid in fees. At December 31, 2006,
      the Portfolio had securities valued at $58,440,217 on loan of which,
      $61,835,718 was collateralized with cash and $247,825 was collateralized
      with securities. See the Schedule of Investments for further detail on the
      security positions on loan and investment of cash collateral held.

(7)   Delayed Delivery Transactions:

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

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

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

      At December 31, 2006, the Portfolio held delayed delivery securities. See
      the Schedule of Investments for further details.

(8)   Line of Credit:

      The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
      Trust are parties to a committed line of credit facility, which enables
      each portfolio/fund to borrow, in the aggregate, up to $35 million.
      Interest is charged to each participating portfolio/fund based on its
      borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
      1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1%
      on the committed amount, is allocated ratably among the participating
      portfolios/funds at the end of each quarter. The Fund/Portfolio also pays
      an annual renewal fee, computed at a rate of 0.020 of 1% of the committed
      amount and allocated ratably to the participating funds/portfolios. For
      the year ended December 31, 2006, the expense allocated to the Portfolio
      was $3,294. The facility fee and interest expense are included in
      miscellaneous expenses on the statement of operations.

      For the year ended December 31, 2006, the Portfolio had average borrowings
      outstanding of $12,000 for a total of three days and incurred $6 of
      interest expense. At December 31, 2006 the Fund had no borrowings
      outstanding.

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

To the Trustees of Mellon Institutional Funds Master Portfolio and Investors of
Standish Mellon Fixed Income Portfolio:

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 present fairly, in all
material respects, the financial position of Standish Mellon Fixed Income
Portfolio (the "Portfolio") at December 31, 2006, 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 Portfolio'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, 2006 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

                  Mellon Institutional Funds Master Portfolio
                     Standish Mellon Fixed Income Portfolio

     Factors Considered by Mellon Trustees in Approving 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. The
      Fund is not a party to an investment advisory agreement directly with any
      investment adviser and does not invest directly in portfolio securities.
      Instead, the Fund invests all of its investable assets in the Standish
      Mellon Fixed Income Portfolio (the "Portfolio"), which is managed by
      Standish Mellon Asset Management Company LLC ("Standish Mellon"). The
      Fund's Board of Trustees determines annually whether the Fund should
      continue to invest in the Portfolio. The members of the Fund's Board of
      Trustees also serve as the Board of Trustees of the Portfolio. In that
      capacity, they consider annually whether to continue the investment
      advisory agreement between the Portfolio and 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 the Portfolio's investment adviser,
      Standish Mellon ("the Adviser") a broad range of information in response
      to a written request prepared on their behalf by their own legal counsel.
      The Independent Trustees met alone in a private session with their legal
      counsel on September 28, 2006 to review these materials and to discuss the
      proposed continuation of the Fund's advisory agreement. Representatives of
      the Adviser attended a portion of the September meeting to provide an
      overview of its organization, personnel, resources and strategic plans,
      and to respond to questions and comments arising from the Independent
      Trustees' review of the materials and their deliberations. The entire
      Board then met on October 17, 2006.

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

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

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

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

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

      (v) Other Benefits: The benefits flowing to Mellon Financial Corporation
      ("Mellon") and its affiliates in the form of fees for transfer agency,
      custody, administration and securities lending services provided to the
      Funds by affiliates of 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 Master Portfolio
                     Standish Mellon Fixed Income Portfolio

     Factors Considered by Mellon Trustees in Approving 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 28, 2006 Board meeting, the Trustees received similar detailed
      comparative performance information for the Fund at each regular Board
      meeting during the year.

      The Board considered the Fund's performance for the one-, three- and
      five-year periods ended July 31, 2006 based on the Lipper materials
      provided to the Board at the September 28, 2006 meeting. The Board found
      that the Fund outperformed its peer group average return for the one-year
      period (1.47% vs. 1.40%), three-year period (4.46% vs. 4.20%) and
      five-year period (4.95% vs. 4.87%).

      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 0.376% (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), in the 1st quintile (best) of
      its peer group of funds, the median fee of which was 0.440%. The
      Portfolio's net management fee was 0.427% (which included 0.05% in
      administrative service fees under Lipper's calculation methodology),
      slightly higher than the peer group median net management fee of 0.40%.
      Based on the Lipper data, as well as other factors discussed at the
      September 28, 2006 meeting, the Board determined that the Portfolio's
      advisory fee is reasonable relative to its peer group averages.

      The Board also compared the fees payable by the Portfolio relative to
      those payable by separate account clients of the Adviser. Based on the
      additional scope and complexity of the services provided and
      responsibilities assumed by the Adviser with respect to the Portfolio
      relative to these other types of clients, the Board concluded that the
      fees payable under the advisory agreement were reasonable relative to the
      nature and quality of 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 0.485% was slightly
      higher than the median net expense ratio of the peer group of 0.479%
      largely due to the Fund's small asset size compared to its peer group.

      The Adviser's Profitability

      The Board considered the Adviser's profitability in managing the Portfolio
      and Fund and the Mellon Institutional Funds as a group, as well as the
      methodology used to compute such profitability, and the various direct and
      indirect expenses incurred by the Adviser or its affiliated investment
      adviser, The Boston Company Asset Management, LLC ("TBCAM") in managing
      the Portfolio and other funds in the Mellon Institutional Funds family of
      funds. The Independent Trustees had observed that the Adviser, based on
      profitability information submitted to them by the Adviser, incurred
      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 2004
      and 2005 and concluded these were not excessive.

      Economies of Scale

      The Board also considered the extent to which economies of scale might be
      realized as the Fund grows. They observed that the Fund and the 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 Mellon Trustees in Approving Advisory Agreements
                                   (Unaudited)
- --------------------------------------------------------------------------------

      Other Benefits

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

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

                                      * * *

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

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2006.

Financial markets showed substantial resilience in 2006, shrugging off concerns
that the slowdown in the housing market could drag the rest of the economy into
recession. The U.S. Federal Reserve (Fed) paused in its tightening cycle in
August, after 17 rate hikes since June 2004, as the Fed became convinced that
inflationary forces, and expectations, were under control. Perhaps the most
notable feature of this cycle is that the housing bubble is bursting at a time
when rates are not high. In previous cycles, housing market declines typically
follow a period of Fed tightenings that drive rates to extreme levels, choking
off credit, including mortgage financing. In this environment, credit for
housing and other sectors remains plentiful, with the housing pullback largely a
function of prices soaring beyond affordable levels for many prospective buyers.

The stock market climbed the proverbial "wall of worry" during 2006, with the
S&P 500 hitting new highs and providing a gain of 15.8%, including an 8.8%
advance in the fourth quarter. With U.S. monetary policy
moderating, energy prices in a swoon and the inflation threat receding,
investors clearly feel that the case for a soft landing is being reinforced.

In the bond markets, short-term rates advanced steadily, for the most part, in
cadence with the Fed's rate increases, with the 6-month Treasury bill ending the
year at 4.9%, up about 70 basis points. Rates on longer-term bonds increased to
a lesser degree, with the 10-year Treasury note ending about 30 basis points
higher at 4.7%. This produced an inverted yield curve, which is often a leading
indicator of recession.

Going forward, there is still much debate over the impact of the housing
downturn on the overall economy. We believe that the housing market is in for
prolonged weakness, because rates are already at relatively modest levels. Thus,
the boost provided by lower mortgage rates in the future is likely to be smaller
for housing than in it has been in previous cycles. However, there are other
bullish factors that should mitigate the drag of the housing market. As noted,
liquidity remains plentiful, and corporations are flush with cash. Spreads of
high yield bonds above Treasuries remain tight - an indicator that credit is
still available for riskier borrowers. High yield spreads tend to widen when the
market perceives a recession is likely.

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,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS

The economy continued to grow in 2006, though at a declining pace as the year
progressed. After a very strong first quarter, weakness in the U.S. housing
sector began to emerge, reducing the overall level of economic activity. On a
year-over-year basis, real gross domestic product grew at an approximate 3%
pace, down from the prior year, but still near the long-term trend growth rate
of the economy. Strong employment, high corporate profitability and continued
solid retail sales offset weak housing and automobile sectors.

The U.S. Federal Reserve (Fed) raised the federal funds rate five times from
December 13, 2005 to June 29, 2006, for a total increase of 100 basis points, to
its current 5.25% level. Since August, the Fed has left the federal funds rate
unchanged, citing moderating economic activity related to the housing market.
The last rate increase by the Fed in June coincided with the peak in long-term
interest rates during the year. Both 2-year and 10-year Treasury notes began
the year yielding approximately 4.40%. But by late June, both had risen
approximately 85 basis points to 5.25%. Since that time, however, long-term
interest rates have fallen at a more rapid pace than short-term interest rates,
with the 2-year note at year end yielding 4.81% and the 10-year note yielding
4.70%.

The prospects for 2007 are mixed. Employment and retail spending remain strong
and credit conditions are easy. But the potential still exists that the slowdown
in the U.S. housing market will gradually extend into other sectors, possibly
leading to a recession. With headline inflation beginning to decline, the Fed
has room to ease interest rates, if necessary. However, with the economy
apparently still expanding at near-trend growth, the Fed's current policy is to
wait for further signals from the economy before acting.

For 2006, the Standish Mellon Yield Plus Fund (Fund) returned 5.00%, under
performing its benchmark, the Merrill Lynch (ML) Constant Maturity 3-month LIBOR
Index, which returned 5.12%. (In September, the Fund's benchmark was changed
from the 6-month Treasury Bill to its current benchmark.) The Fund was
negatively affected by the increase in interest rates during the first half of
the year, and until September, the Fund's holdings had an approximate duration
of 6 months, as compared to a 3-month duration period of the Fund's new
benchmark. Offsetting this duration effect, the Fund benefited from its strong
overweight position in higher yielding corporate and asset-backed securities,
which had yields in excess of LIBOR. These holdings also benefited from the
continued narrowing in credit spreads during the year.

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.

(1)   The ML Constant Maturity 3-month Libor Index is an unmanaged index of
      3-month constant maturity dollar-denominated deposits derived from
      interest rates on the most recent available dollar-denominated deposits.
      An individual cannot invest directly in the index. Effective September 1,
      2006, the fund changed its benchmark from the ML 6-month US Treasury Bill
      Index to the ML Constant Maturity 3-month Libor Index because the adviser
      believes the ML Constant Maturity 3-month Libor Index is more consistent
      with the characteristics, credit quality and duration target of the fund
      given the investments, strategies, and other characteristics reflected in
      this supplement.

                    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, 2006 to December 31, 2006).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000=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 0.35%,
      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 YIELD PLUS 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 Yield Plus Fund (the "Fund") is a separate
      diversified investment series of the Trust.

      The Fund's Board of Trustees approved, effective September 1, 2006, the
      change in the Fund's name from "Standish Mellon Enhanced Yield Fund" to
      "Standish Mellon Yield Plus Fund".

      The objective of the Fund is to achieve a high level of current income
      consistent with preserving principal and liquidity. The Fund invests all
      of its investable assets in an interest of Standish Mellon Yield Plus
      Portfolio (the "Portfolio"), a subtrust of Mellon Institutional Funds
      Master Portfolio (the "Portfolio Trust"), which is organized as a New York
      trust and has the same investment objective as the Fund. The Portfolio
      seeks to achieve its objective by investing, under normal circumstances,
      at least 80% of net assets in dollar-denominated money market instruments,
      short-term fixed income securities and asset-backed securities of U.S. and
      foreign governments, banks and companies. The value of the Fund's
      investment in the Portfolio reflects the Fund's proportionate interest in
      the net assets of the Portfolio (100% at December 31, 2006). The
      performance of the Fund is directly affected by the performance of the
      Portfolio. The financial statements of the Portfolio are included
      elsewhere in this report and should be read in conjunction with the Fund's
      financial statements.

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

      A. INVESTMENT SECURITY VALUATIONS

      Fund shares are valued as of the close of regular trading (normally 4:00
      p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
      is open. The Fund records its investment in the Portfolio at value. The
      Portfolio values its securities at value as discussed in Note 1A of the
      Portfolio's Notes to Financial Statements, which are included elsewhere in
      this report.

      B. SECURITIES TRANSACTIONS AND INCOME

      The Fund's investment in the Portfolio is recorded on settlement date. The
      Portfolio's securities transactions are recorded as of the trade date as
      discussed in Note 1B of the Portfolio's Notes to Financial Statements,
      which are included elsewhere in this report. Currently, the Fund's net
      investment income consists of the Fund's pro rata share of the net
      investment income of the Portfolio, less all expenses of the Fund
      determined in accordance with accounting principles generally accepted in
      the United States of America. All realized and unrealized gains and losses
      of the Fund represent pro rata shares of gains and losses of the
      Portfolio.

      C. DISTRIBUTIONS TO SHAREHOLDERS

      Distributions to shareholders are recorded on the ex-dividend date. The
      Fund's distributions from capital gains, if any, after reduction of
      capital losses are declared and distributed at least annually. In
      determining the amounts of its dividends, the Fund will take into account
      its share of the income, gains or losses, expenses, and any other tax
      items of the Portfolio. Dividends from net investment income and
      distributions from capital gains, if any, are reinvested in additional
      shares of the Fund unless a shareholder elects to receive them in cash.

      Income and capital gain distributions are determined in accordance with
      income tax regulations, which may differ from accounting principles
      generally accepted in the United States of America. These differences
      which may result in reclassifications, are primarily due to differing
      treatments for losses deferred due to post-October losses, capital loss
      carryovers, and the timing of recognition of realized and unrealized gains
      and losses on futures contracts.

      Permanent book and tax basis differences relating to shareholder
      distributions will result in reclassifications among undistributed net
      investment income(loss), accumulated net realized gain (loss) and paid in
      capital. Undistributed net investment income (loss) and accumulated net
      realized gain (loss) on investments may include temporary book and tax
      basis differences which will reverse in a subsequent period. Any taxable
      income or gain remaining at fiscal year end is distributed in the
      following year.

      D. EXPENSES

      The majority of expenses of the Trust or Portfolio Trust are directly
      identifiable to an individual fund or portfolio. Expenses which are not
      readily identifiable to a specific fund or portfolio are allocated among
      funds of the Trust and portfolios of the Portfolio Trust taking into
      consideration, among other things, the nature and type of expense and the
      relative size of the funds or portfolios.

                        STANDISH MELLON YIELD PLUS FUND

                         NOTES TO FINANCIAL STATEMENTS

      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. FEDERAL INCOME 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.

(2)   INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

      The Fund does not directly pay any investment advisory fees, but
      indirectly bears its pro rata share of the compensation paid by the
      Portfolio to Standish Mellon Asset Management Company LLC ("Standish
      Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, for
      such services. See Note 2 of the Portfolio's Notes to Financial
      Statements, which are included elsewhere in this report. Standish Mellon
      voluntarily agreed to limit the total operating expenses of the Fund and
      its pro rata share of the Portfolio expenses (excluding brokerage
      commissions, taxes and extraordinary expenses) to 0.25% of the Fund's
      average daily net assets for the period January 1, 2006 to August 31, 2006
      and to 0.40% for the period from September 1, 2006 to December 31, 2006.
      Pursuant to this agreement, for the year ended December 31, 2006, Standish
      Mellon voluntarily reimbursed the Fund for $69,172 of its operating
      expenses. This agreement is voluntary and temporary and may be
      discontinued or revised by Standish Mellon at any time.

      On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
      New York Company, Inc. ("BNY") announced that they had entered into a
      definitive agreement to merge. The new company will be called The Bank of
      New York Mellon Corporation. As part of this transaction, Standish Mellon
      would become an indirect wholly-owned subsidiary of The Bank of New York
      Mellon Corporation. The transaction is subject to certain regulatory
      approvals and the approval of BNY's and MFC's shareholders, as well as
      other customary conditions to closing. Subject to such approvals and the
      satisfaction of the other conditions, MFC and BNY expect the transaction
      to be completed in the third quarter of 2007.

      The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly
      owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of
      Mellon Financial Corporation and an affiliate of Standish Mellon, to
      provide personnel and facilities to perform transfer agency and certain
      shareholder services for the Fund. For these services, the Fund pays
      Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based
      fees, as well as, out-of-pocket expenses. Pursuant to this agreement the
      Fund was charged $8,293, for the year ended December 31, 2006.

      The Trust has contracted Mellon Investor Services LLC, a wholly owned
      subsidiary of Mellon Financial Corporation and an affiliate of Standish
      Mellon, to provide printing and fulfillment services for the Fund.
      Pursuant to this agreement, the Fund was charged $2,740 for the year ended
      December 31, 2006.

      The Trust reimburses Mellon Asset Management for a portion of the salary
      of the Trust's Chief Compliance Officer. For the year ended December 31,
      2006, the Fund was charged $4,005. No other director, officer or employee
      of Standish Mellon or its affiliates receives any compensation from the
      Trust or the Portfolio Trust for serving as an officer or Trustee of the
      Trust. The Fund pays each Trustee who is not a director, officer or
      employee of Standish Mellon or its affiliates an annual fee.

      The Fund pays administrative service fees. These fees are paid to
      affiliated or unaffiliated retirement plans, omnibus accounts and platform
      administrators and other entities ("Plan Administrators") that provide
      record keeping and/or other administrative support services to accounts,
      retirement plans and their participants. As compensation for such
      services, the Fund may pay each Plan Administrator an administrative
      service fee in an amount of up to 0.15% (on an annualized basis) of the
      Fund's average daily net assets attributable to Fund shares that are held
      in accounts serviced by such Plan Administrator. The Fund's adviser or its
      affiliates may pay additional compensation from their own resources to
      Plan Administrators and other entities for administrative services, as
      well as in consideration of marketing or other distribution-related
      services. These payments may provide an incentive for these entities to
      actively promote the Fund or cooperate with the distributor's promotional
      efforts. For the year ended December 31, 2006, the Fund was charged $2,789
      for fees payable to Mellon Private Wealth Management.

(3)   INVESTMENT TRANSACTIONS:

      Increases and decreases in the Fund's investment in the Portfolio for the
      year ended December 31, 2006, aggregated $6,989,509 and $25,868,412,
      respectively. The Fund receives a proportionate share of the Portfolio's
      income, expenses, and realized and unrealized gains and losses based on
      applicable tax allocation rules.

(4)   SHARES OF BENEFICIAL INTEREST:

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



                                                           FOR THE                       FOR THE

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


      At December 31, 2006, two shareholders of record held in the aggregate
      approximately 52% of the total outstanding shares of the Fund. Investment
      activities of these shareholders could have a material impact on the Fund.

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

(5)   FEDERAL TAXES:

      As of December 31, 2006, the components of distributable earnings on a tax
      basis were as follows:


                                       
Undistributed ordinary income             $         __
Undistributed capital gains                         __
Total distributable earnings                        __
Capital loss carry forward                $  2,411,660


      Tax character of distributions paid during the fiscal year ended December
      31, 2006, were as follows:



                                          2006                             2005
                                      -----------                      -----------
                                                                 
Ordinary income                       $ 1,476,693                      $ 1,940,395


      At December 31, 2006, 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
- -------------                      ---------------

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


      Utilization of the capital loss carryovers above could be subject to
      limitations imposed by the Internal Revenue Code related to share
      ownership activity. At December 31, 2006, $80,787 in capital loss
      carryovers expired.

      The Fund elected to defer to its fiscal year ending December 31, 2007
      $54,389 of capital losses recognized during the period November 1, 2006 to
      December 31, 2006.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees of Mellon Institutional Funds Investment Trust and Shareholders
of Standish Mellon Yield Plus Fund:

In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Standish Mellon Yield Plus Fund, formerly Standish Mellon Enhanced Yield Fund,
(the "Fund") at December 31, 2006, 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
agreement of the amount of the investment in the Portfolio at December 31, 2006
to the Portfolio's records, provide a reasonable basis for our opinion.

                      STANDISH MELLON YIELD PLUS PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS

(1)   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES:

      Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
      organized as a master trust fund under the laws of the State of New York
      on January 18, 1996 and is registered under the Investment Company Act of
      1940, as amended, as an open-end, management investment company. Standish
      Mellon Yield Plus Portfolio (the "Portfolio") is a separate diversified
      investment series of the Portfolio Trust.

      The Fund's Board of Trustees approved, effective September 1, 2006, the
      change in the Fund's name from "Standish Mellon Enhanced Yield Portfolio"
      to "Standish Mellon Yield Plus Portfolio".

      The objective of the Portfolio is to achieve a high level of current
      income consistent with preserving principal and liquidity. The Portfolio
      seeks to achieve its objective by investing, under normal circumstances,
      at least 80% of net assets in dollar-denominated money market instruments,
      short-term fixed income securities and asset-backed securities of U.S. and
      foreign governments, banks and companies.

      At December 31, 2006 there was one fund, Standish Mellon Yield Plus Fund
      (the "Fund"), invested in the Portfolio. The value of the Fund's
      investment in the Portfolio reflects the Fund's proportionate interest in
      the net assets of the Portfolio. The Fund's proportionate interest at
      December 31, 2006 was 100%.

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

      A. INVESTMENT SECURITY VALUATIONS

      Securities are valued at the last sale prices on the exchange or national
      securities market on which they are primarily traded. Securities not
      listed on an exchange or national securities market, or securities for
      which there were no reported transactions, are valued at the last quoted
      bid price. Securities that are fixed income securities, other than
      short-term instruments with less than sixty days remaining to maturity,
      for which 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.

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

      Short-term instruments with less than sixty days remaining to maturity are
      valued at amortized cost, which approximates market value. If the
      Portfolio acquires a short-term instrument with more than sixty days
      remaining to its maturity, it is valued at current market value until the
      sixtieth day prior to maturity and then is valued at amortized cost based
      upon the value on such date unless the Trustees determine during such
      sixty-day period that amortized cost does not represent fair value.

      B. SECURITIES TRANSACTIONS AND INCOME

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

      C. INCOME TAXES

      The Portfolio is treated as a disregarded entity for federal tax purposes.
      No provision is made by the Portfolio for federal or state income taxes on
      any taxable income of the Portfolio because each investor in the Portfolio
      is ultimately responsible for the payment of any taxes. Since the
      Portfolio's investor is a regulated investment company that invests all or
      substantially all of its assets in the Portfolio, the Portfolio normally
      must satisfy the source of income and diversification requirements
      applicable to regulated investment companies (under the Internal Revenue
      Code) in order for its investors to satisfy them.

                         NOTES TO FINANCIAL STATEMENTS

      D. COMMITMENTS AND CONTINGENCIES

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

      E. EXPENSES

      The majority of expenses of the Trust or Portfolio Trust are directly
      identifiable to an individual fund or portfolio. Expenses which are not
      readily identifiable to a specific fund or portfolio are allocated among
      funds of the Trust or portfolios of the Portfolio Trust taking into
      consideration, among other things, the nature and type of expense and the
      relative size of the funds or portfolios.

      F. AFFILIATED ISSUERS

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

      G. NEW ACCOUNTING REQUIREMENTS

      In July 2006, the Financial Accounting Standards Board issued
      Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
      Interpretation of FASB Statement No. 109" (the "Interpretation"). The
      Interpretation establishes for all entities, including pass-through
      entities such as the Portfolio, a minimum threshold for financial
      statement recognition of the benefit of positions taken in filing tax
      returns (including whether an entity is taxable in a particular
      jurisdiction), and requires certain expanded tax disclosures. Adoption of
      FIN 48 is required for fiscal years beginning after December 15, 2006 and
      is to be applied to all open tax years as of the effective date. At this
      time, management is evaluating the implications of FIN 48 and its impact,
      if any, in the financial statements has not yet been determined.

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

(2)   INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

      The investment advisory fee paid to Standish Mellon for overall investment
      advisory, administrative services, and general office facilities is paid
      monthly at the annual rate of 0.20% of the Portfolio's average daily net
      assets. Standish Mellon voluntarily agreed to limit the total operating
      expenses of the Fund and its pro rata share of the Portfolio expenses
      (excluding brokerage commissions, taxes and extraordinary expenses) to
      0.25% of the fund's average daily net assets for the period January 1,
      2006 through August 31, 2006 and 0.40% for the period September 1, 2006 to
      December 31, 2006. Pursuant to these agreements, for the year ended
      December 31, 2006, Standish Mellon voluntarily waived a portion of its
      investment advisory fee in the amount of $64,675 and reimbursed the
      Portfolio $14,185 of other operating expenses. This agreement is voluntary
      and temporary and may be discontinued or revised by Standish Mellon at any
      time.

      On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
      New York Company, Inc. ("BNY") announced that they had entered into a
      definitive agreement to merge. The new company will be called The Bank of
      New York Mellon Corporation. As part of this transaction, Standish Mellon
      would become an indirect wholly-owned subsidiary of The Bank of New York
      Mellon Corporation. The transaction is subject to certain regulatory
      approvals and the approval of BNY's and MFC's shareholders, as well as
      other customary conditions to closing. Subject to such approvals and the
      satisfaction of the other conditions, MFC and BNY expect the transaction
      to be completed in the third quarter of 2007.

      The Portfolio Trust has entered into an agreement with Mellon Bank, N.A.
      ("Mellon Bank"), a wholly owned subsidiary of Mellon Financial Corporation
      and an affiliate of Standish Mellon, to provide custody, administration
      and fund accounting services for the Portfolio. For these services the
      Portfolio pays Mellon Bank a fixed fee plus asset and transaction based
      fees, as well as out-of-pocket expenses. Pursuant to this agreement the
      Portfolio was charged $66,526 during the year ended December 31, 2006.

                                       22

                         NOTES TO FINANCIAL STATEMENTS

      The Portfolio Trust also entered into an agreement with Mellon Bank to
      perform certain securities lending activities and to act as the
      Portfolio's lending agent. Mellon Bank receives an agreed upon percentage
      of the net lending revenues. Pursuant to this agreement, Mellon Bank
      earned $119 for the year ended December 31, 2006. See Note 6 for further
      details.

      The Trust reimburses Mellon Asset Management for a portion of the salary
      of the Trust's and Portfolio Trust's Chief Compliance Officer. No other
      director, officer or employee of Standish Mellon or its affiliates
      received any compensation from the Trust or the Portfolio Trust for
      serving as an officer or Trustee of the Trust or the Portfolio Trust. The
      Fund and Portfolio Trust pays each Trustee who is not a director, officer
      or employee of Standish Mellon or its affiliates (the "Independent
      Trustees") an annual fee and the Portfolio Trust pays each Independent
      Trustee a per meeting fee as well as reimbursement for travel and out of
      pocket expenses. In addition, the Portfolio Trust pays the legal fees for
      the counsel to the Independent Trustees.

      obligations, for the year ended December 31, 2006 were as follows:

(5)   FINANCIAL INSTRUMENTS:

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

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

      FUTURES CONTRACTS

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

      At December 31, 2006, the Portfolio held open financial futures contracts.
      See the Schedule of Investments for further details.

                         NOTES TO FINANCIAL STATEMENTS

      SWAP AGREEMENTS

      The Portfolio may enter into swap agreements. A swap is an agreement to
      exchange the return generated by one instrument for the return generated
      by another instrument. The Portfolio may enter into interest rate, credit
      default and total return swap agreements to manage its exposure to
      interest rates and credit risk. Interest rate swap agreements involve the
      exchange by the Portfolio with another party of their respective
      commitments to pay or receive interest, e.g., an exchange of floating rate
      payments for fixed rate payments with respect to a notional amount of
      principal. In a credit default swap, one party makes a stream of payments
      to another party in exchange for the right to receive a specified return
      in the event of a default by a third party on its obligation. The
      Portfolio may use credit default swaps to provide a measure of protection
      against defaults of issuers (i.e., to reduce risk where the Portfolio owns
      or has exposure to the corporate or sovereign issuer) or to take an active
      long or short position with respect to the likelihood of a particular
      corporate or sovereign issuer's default. Total return swap agreements
      involve commitments to pay interest in exchange for a market-linked
      return, both based on notional amounts. To the extent the total return of
      the security or index underlying the transaction exceeds or falls short of
      the offsetting interest rate obligation, the portfolio will receive a
      payment from or make a payment to the counterparty. In connection with
      these agreements, cash or securities may be set aside as collateral in
      accordance with the terms of the swap agreement. The Portfolio earns
      interest on cash set aside as collateral. Swaps are marked to market daily
      based upon quotations, which may be furnished by a pricing service or
      dealers in such securities, and the change in value, if any, is recorded
      as unrealized appreciation or depreciation in the Statement of Operations.
      These financial instruments are not actively traded on financial markets.
      The values assigned to these instruments are based upon the best available
      information and because of the uncertainty of the valuation, these values
      may differ significantly from the values that would have been realized had
      a ready market for these instruments existed, and differences could be
      material. Payments received or made at the beginning of the measurement
      period are reflected as such on the Statement of Assets and Liabilities.
      Payments received or made from credit default swaps at the end of the
      measurement period are recorded as realized gain or loss in the Statement
      of Operations. Net payments of interest on interest rate swap agreements,
      if any, are included as part of realized gain and loss. Entering into
      these agreements involves, to varying degrees, elements of credit, market,
      and documentation risk in excess of the amounts recognized in the
      Statement of Assets and Liabilities. Such risks involve the possibility
      that there will be no liquid market for these agreements, that the
      counterparty to the agreements may default on its obligation to perform or
      disagree as to the meaning of contractual terms in the agreements, and
      that there may be unfavorable changes in interest rates.

      At December 31, 2006, the Portfolio did not hold any swap agreements.

(6)   SECURITY LENDING:

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

      The Portfolio loaned securities during the year ended December 31, 2006
      and earned interest on the invested collateral of $17,816 of which,
      $17,535 was rebated to borrowers or paid in fees. At December 31, 2006,
      the Portfolio had securities valued at $349,478 on loan. See the Schedule
      of Investments for further detail on the security positions on loan and
      collateral held.

(7)   LINE OF CREDIT:

      The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
      Trust are parties to a committed line of credit facility, which enables
      each portfolio/fund to borrow, in the aggregate, up to $35 million.
      Interest is charged to each participating portfolio/fund based on its
      borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
      1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1%
      on the committed amount, is allocated ratably among the participating
      portfolios/funds at the end of each quarter. The Fund/Portfolio also pays
      an annual renewal fee, computed at a rate of 0.020 of 1% of the committed
      amount and allocated ratably to the participating funds/portfolios. For
      the year ended December 31, 2006, the expense allocated to the Portfolio
      was $50. The commitment fee is aggregated with miscellaneous expenses on
      the Statement of Operations.

      For the year ended December 31, 2006, the Portfolio did not borrow from
      the line of credit.

                      STANDISH MELLON YIELD PLUS PORTFOLIO

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees of Mellon Institutional Funds Master Portfolio and Investors of
Standish Mellon Yield Plus Portfolio:

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 present fairly, in all
material respects, the financial position of Standish Mellon Yield Plus
Portfolio, formerly Standish Mellon Enhanced Yield Portfolio, (the "Portfolio")
at December 31, 2006, 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
Portfolio'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, 2006 by correspondence with the custodian and brokers, provide a
reasonable basis for our opinion.

                      STANDISH MELLON YIELD PLUS PORTFOLIO

    FACTORS CONSIDERED BY BOARD OF TRUSTEES IN APPROVING ADVISORY AGREEMENT
                                  (UNAUDITED)

The 1940 Act requires that the Board of Trustees, including a majority of its
Trustees who are not affiliated with the fund's investment adviser or
underwriter (the "Independent Trustees") voting separately, approve the fund's
advisory agreement and the related fees on an annual basis. The Fund is not a
party to an investment advisory agreement directly with any investment adviser
and does not invest directly in portfolio securities. Instead, the Fund invests
all of its investable assets in the Standish Mellon Yield Plus Portfolio (the
"Portfolio"), which is managed by Standish Mellon Asset Management Company LLC
("Standish Mellon"). The Fund's Board of Trustees determines annually whether
the Fund should continue to invest in the Portfolio. The members of the Fund's
Board of Trustees also serve as the Board of Trustees of the Portfolio. In that
capacity, they consider annually whether to continue the investment advisory
agreement between the Portfolio and 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 the
Portfolio's investment adviser, Standish Mellon (the "Adviser") a broad range of
information in response to a written request prepared on their behalf by their
own legal counsel. The Independent Trustees met alone in a private session with
their legal counsel on September 28, 2006 to review these materials and to
discuss the proposed continuation of the Fund's advisory agreement.
Representatives of the Adviser attended a portion of the September meeting to
provide an overview of its organization, personnel, resources and strategic
plans, and to respond to questions and comments arising from the Independent
Trustees' review of the materials and their deliberations. The entire Board then
met on October 17, 2006.

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

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

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

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

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

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

                      STANDISH MELLON YIELD PLUS PORTFOLIO

    FACTORS CONSIDERED BY BOARD OF TRUSTEES IN APPROVING ADVISORY AGREEMENT
                                  (UNAUDITED)

INVESTMENT PERFORMANCE

The Board considered the investment performance of the Fund (rather than the
Portfolio alone) against a peer group of investment companies selected by the
Adviser with input from the Trustees. The Board also compared the Fund's
investment performance against the average performance of a larger universe of
funds regarded by Lipper as having similar investment objectives and considered
the Fund's performance rankings against that universe. In addition to the
information received by the Board at the September 28, 2006 Board meeting, the
Trustees received similar detailed comparative performance information for the
Fund at each regular Board meeting during the year.

The Board considered the Fund's performance for the one-, three- and five-year
periods ended July 31, 2006 based on the Lipper materials provided to the Board
at the September 28, 2006 meeting. The Board found that the Fund outperformed
its peer group average returns for the one-year period (4.19% vs. 3.97%) and the
five-year period (2.61% vs. 2.50%), but underperformed its peer group average
returns for the three-year period (2.23% vs. 2.41%).

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 0.20%, in the 1st (best) quintile
of its peer group of funds, the median fee of which was 0.37%. The Portfolio's
net management fee, after giving effect to expense limitations, was 0.057%
(which included administrative services fees under Lipper's calculation
methodology), well below the peer group median net management fee of 0.288%.
Based on the Lipper data, as well as other factors discussed at the September
28, 2006 meeting, the Board determined that the Portfolio's advisory fee is
reasonable relative to its peer group averages, both with and without giving
effect to expense limitations.

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 0.322% (after giving effect to
expense limitations) was lower than the median net expense ratio of the peer
group of 0.37%, notwithstanding the fact that all of the other funds in the peer
group were larger than the Fund.

THE ADVISER'S PROFITABILITY

The Board considered the Adviser's profitability in managing the Portfolio and
Fund and the Mellon Institutional Funds as a group, as well as the methodology
used to compute such profitability, and the various direct and indirect expenses
incurred by the Adviser or its affiliated investment adviser, The Boston Company
Asset Management, LLC ("TBCAM") 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, including the
Portfolio and Fund. The Trustees observed that the Adviser had incurred losses
in operating the Portfolio and Fund in both 2004 and 2005.

ECONOMIES OF SCALE

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

    FACTORS CONSIDERED BY BOARD OF TRUSTEES IN APPROVING ADVISORY AGREEMENT
                                  (UNAUDITED)

OTHER BENEFITS

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

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

                                     * * *

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

February 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2006.

Financial markets showed substantial resilience in 2006, shrugging off concerns
that the slowdown in the housing market could drag the rest of the economy into
recession. The U.S. Federal Reserve (Fed) paused in its tightening cycle in
August, after 17 rate hikes since June 2004, as the Fed became convinced that
inflationary forces, and expectations, were under control. Perhaps the most
notable feature of this cycle is that the housing bubble is bursting at a time
when rates are not high. In previous cycles, housing market declines typically
follow a period of Fed tightenings that drive rates to extreme levels, choking
off credit, including mortgage financing. In this environment, credit for
housing and other sectors remains plentiful, with the housing pullback largely a
function of prices soaring beyond affordable levels for many prospective buyers.

The stock market climbed the proverbial "wall of worry" during 2006, with the
S&P 500 hitting new highs and providing a gain of 15.8%, including an 8.8%
advance in the fourth quarter. With U.S. monetary policy moderating, energy
prices in a swoon and the inflation threat receding, investors clearly feel that
the case for a soft landing is being reinforced.

In the bond markets, short-term rates advanced steadily, for the most part, in
cadence with the Fed's rate increases, with the 6-month Treasury bill ending the
year at 4.9%, up about 70 basis points. Rates on longer-term bonds increased to
a lesser degree, with the 10-year Treasury note ending about 30 basis points
higher at 4.7%. This produced an inverted yield curve, which is often a leading
indicator of recession.

Going forward, there is still much debate over the impact of the housing
downturn on the overall economy. We believe that the housing market is in for
prolonged weakness, because rates are already at relatively modest levels. Thus,
the boost provided by lower mortgage rates in the future is likely to be smaller
for housing than in it has been in previous cycles. However, there are other
bullish factors that should mitigate the drag of the housing market. As noted,
liquidity remains plentiful, and corporations are flush with cash. Spreads of
high yield bonds above Treasuries remain tight - an indicator that credit is
still available for riskier borrowers. High yield spreads tend to widen when the
market perceives a recession is likely.

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,

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

The first part of 2006 was a challenging environment for global bonds as G3
(U.S., Europe and Japan) 10-year yields rose 40 basis points. During the
remainder of the year, bonds rallied on weak economic data and a slowing housing
market.

The predominant drivers of G3 yields were the continued tightening by the U.S.
Federal Reserve (Fed) until July, as well as the steady diet of rate hikes from
the European Central Bank (ECB) and the Bank of Japan (BoJ). The BoJ tightening
cycle is truly groundbreaking as the zero interest rate policy ended and is a
signal that Japan is finally returning to sustainable economic growth.

This environment was made more challenging by significant reversals in the
direction of bond yields during 2006. The first half of 2006 saw global bond
yields rise, only to peak in June and then reverse direction for the remainder
of the year. Fortunately, Standish Mellon International Fixed Income Fund (Fund)
was well positioned to capture this shift in bond yields. The Fund was short in
duration at the start of 2006, yet after the Fed tightened interest rates and
the U.S. housing market displayed serious signs of weakness, the Fund's holdings
were reallocated to longer duration bonds to take advantage of a potential drop
in interest rates in the U.S. As the Fed held interest rates steady in July,
global bonds started a hesitant rally that carried yields of the U.S. 10-year
Treasury from 5.25% all the way down to 4.4% by November.

The tight correlation between global bond yields in 2006 saw European and
Japanese bond yields rally alongside U.S. yields in the second half of the year,
despite their central banks' rate hikes. U.S. bonds outperformed in the second
half but for the year as a whole, Japanese bonds were the best performers,
followed by Canadian bonds.

In November, the U.S. dollar began to slide relative to the euro as investors
reacted to the weaker outlook for the U.S., and the bond market started to
discount interest rate cuts by the Fed expected in 2007. The dollar fell
broadly, but the Japanese yen continues to be the funding currency of choice,
which has kept the currency on the weak and cheap.

The riskiest corners of the global bond markets, such as high yield and emerging
market debt, generated the highest absolute returns in 2006, and the 4th quarter
was no exception. Spread sectors were fair to rich, and as a result we
tactically reduced credit exposure of the Fund. However, if spreads widen, we
will welcome increased volatility and add credit and emerging exposure.

The Fund's 4.27% return outperformed its benchmark, the J.P. Morgan Non-U.S.
Government Bond Index (Hedged), which returned 3.10% in 2006. Our global short
duration stance and slight extension, as yields peaked later in the year,
contributed to this positive performance during this period. Our country
positioning was also a significant contributor to positive performance as we
positioned the Fund overweight in U.S. bonds in the summer and short in European
and U.K. bonds for most of the year. Although we positioned the Fund to have
neutral exposure to Japanese bonds, which were the best performing, we were
"barbelled" in

Japan and benefited as the yield curve flattened. The Fund's allocation to
emerging market bonds and exposure to high yield bonds, which produced some of
the best performance in all of fixed income, contributed positively to Fund
performance during the year. In addition, the Fund's allocation to Polish local
currency bonds performed well in the latter part of 2006 and continues to be a
solid contributor.

Globally, bonds rallied early in the fourth quarter but sold off strongly in
December and our long duration exposure detracted from performance. We
anticipate global bonds to perform well in 2007 as economic growth slows and
inflation risks fade away.

During the year David Leduc replaced Charles Dolan as a co-portfolio manager of
the Fund. Thomas Fahey continues as the Fund's other co-portfolio manager.

We appreciate your continued investment in the Fund and look forward to working
on your behalf over the next year.

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, 2006 to December 31, 2006).

Actual Expenses

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000=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 0.71%,
      multiplied by the average account value over the period, multiplied by
      184/365 (to reflect the one-half year period).

                   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.

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

      A. Investment security valuations

      Fund shares are valued as of the close of regular trading (normally 4:00
      p.m. Eastern Time) on each day that the New York Stock Exchange ("NYSE")
      is open. Securities are valued at the last sale prices on the exchange or
      national securities market on which they are primarily traded. Securities
      not listed on an exchange or national securities market, or securities for
      which there were no reported transactions, are valued at the last
      calculated mean price (average of last bid and last offer). Securities
      that are fixed income securities, other than short-term instruments with
      less than sixty days remaining to maturity, for which market prices are
      readily available, are valued at their current market value on the basis
      of quotations, which may be furnished by a pricing service or dealers in
      such securities. Securities (including illiquid securities) for which
      quotations are not readily available are valued at their fair value as
      determined in good faith under consistently applied procedures under the
      general supervision of the Trustees.

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

      Short-term instruments with less than sixty days remaining to maturity are
      valued at amortized cost, which approximates market value. If the Fund
      acquires a short-term instrument with more than sixty days remaining to
      its maturity, it is valued at current market value until the sixtieth day
      prior to maturity and then is valued at amortized cost based upon the
      value on such date unless the Trustees determine during such sixty-day
      period that amortized cost does not represent fair value.

      B. Securities transactions and income

      Securities transactions are recorded as of the trade date. Interest income
      is determined on the basis of coupon interest earned, adjusted for
      accretion of discount or amortization of premium using the
      yield-to-maturity method on long-term debt securities and short-term
      securities with greater than sixty days to maturity. Dividend income is
      recorded on 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 (loss) 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 a
      shareholder elects to receive them in cash.

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

                                       18



                   Mellon Institutional Funds Investment Trust
                Standish Mellon International Fixed Income Fund

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

      Permanent book and tax basis differences relating to shareholder
      distributions will result in reclassifications among undistributed net
      investment income(loss), accumulated net realized gain (loss) and paid in
      capital. Undistributed net investment income (loss) and accumulated net
      realized gain (loss) on investments may include temporary book and tax
      basis differences which will reverse in a subsequent period. Any taxable
      income or gain remaining at fiscal year end is distributed in the
      following year.

      Section 988 of the Internal Revenue Code provides that gains or losses on
      certain transactions attributable to fluctuations in foreign currency
      exchange rates must be treated as ordinary income or loss. For financial
      statement purposes, such amounts are included in net realized gains or
      losses.

      D. Foreign currency transactions

      The Fund maintains its books and records in U.S. dollars. Investment
      security valuations, other assets, and liabilities initially expressed in
      foreign currencies are converted into U.S. dollars based upon current
      currency exchange rates. Purchases and sales of foreign investment
      securities and income and expenses are converted into U.S. dollars based
      upon currency exchange rates prevailing on the respective dates of such
      transactions.

      E. Foreign Investment risk

      There are certain additional risks involved in investing in foreign
      securities that are not inherent in investments in domestic securities.
      These risks may involve adverse political and economic developments,
      including the possible imposition of capital controls or other foreign
      governmental laws or restrictions. In addition, the securities of some
      foreign companies and securities markets are less liquid and at times may
      be more volatile than securities of comparable U.S. companies and U.S.
      securities markets. The risks described above apply to an even greater
      extent to investments in emerging markets. The securities markets of
      emerging countries are generally smaller, less developed, less liquid, and
      more volatile than the securities markets of the U.S. and developed
      foreign markets.

      F. Commitments and contingencies

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

      G. Expenses

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

      H. Affiliated issuers

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

      I. New Accounting Requirements

      In July 2006, the Financial Accounting Standards Board issued
      Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
      Interpretation of FASB Statement No. 109" (the "Interpretation"). The
      Interpretation establishes for all entities, including pass-through
      entities such as the Fund, a minimum threshold for financial statement
      recognition of the benefit of positions taken in filing tax returns
      (including whether an entity is taxable in a particular jurisdiction), and
      requires certain expanded tax disclosures. Adoption of FIN 48 is required
      for fiscal years beginning after December 15, 2006 and is to be applied to
      all open tax years as of the effective date. At this time, management is
      evaluating the implications of FIN 48 and its impact, if any, in the
      financial statements has not yet been determined.

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

      J. Federal Income 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.

(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.

      On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
      New York Company, Inc. ("BNY") announced that they had entered into a
      definitive agreement to merge. The new company will be called The Bank of
      New York Mellon Corporation. As part of this transaction, Standish Mellon
      would become an indirect wholly-owned subsidiary of The Bank of New York
      Mellon Corporation. The transaction is subject to certain regulatory
      approvals and the approval of BNY's and MFC's shareholders, as well as
      other customary conditions to closing. Subject to such approvals and the
      satisfaction of the other conditions, MFC and BNY expect the transaction
      to be completed in the third quarter of 2007.

      The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly
      owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of
      Mellon Financial Corporation and an affiliate of Standish Mellon, to
      provide personnel and facilities to perform transfer agency and certain
      shareholder services for the Fund. For these services, the Fund pays
      Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based
      fees, as well as, out-of-pocket expenses. Pursuant to this agreement the
      Fund was charged $5,680, for the year ended December 31, 2006.

      The Trust entered into an agreement with Mellon Bank, N.A. ("Mellon
      Bank"), a wholly owned subsidiary of Mellon Financial Corporation and an
      affiliate of Standish Mellon, to provide custody, administration and 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
      $112,653 during the year ended December 31, 2006.

      The Trust also entered into an agreement with Mellon Bank to perform
      certain securities lending activities and to act as the Fund's lending
      agent. Mellon Bank receives an agreed upon percentage of the net lending
      revenues. Pursuant to this agreement, Mellon Bank earned $1,950 for the
      year ended December 31, 2006. See Note 7 for further details.

      The Trust reimburses Mellon Asset Management for a portion of the salary
      of the Trust's Chief Compliance Officer. For the year ended December 31,
      2006, the Fund was charged $4,029. 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 Mellon Financial Corporation and an affiliate of Standish
      Mellon, to provide printing and fulfillment services for the Fund.
      Pursuant to this agreement the Fund was charged $12,900 for the year ended
      December 31, 2006.

      The Fund pays administrative service fees. These fees are paid to
      affiliated or unaffiliated retirement plans, omnibus accounts and platform
      administrators and other entities ("Plan Administrators") that provide
      record keeping and/or other administrative support services to accounts,
      retirement plans and their participants. As compensation for such
      services, the Fund may pay each Plan Administrator an administrative
      service fee in an amount of up to 0.15% (on an annualized basis) of the
      Fund's average daily net assets attributable to Fund shares that are held
      in accounts serviced by such Plan Administrator. The Fund's adviser or its
      affiliates may pay additional compensation from their own resources to
      Plan Administrators and other entities for administrative services, as
      well as in consideration of marketing or other distribution-related
      services. These payments may provide an incentive for these entities to
      actively promote the Fund or cooperate with the distributor's promotional
      efforts. For the year ended December 31, 2006, the Fund was charged $1,491
      for fees payable to Mellon Private Wealth Management.

      Purchases and proceeds from sales of investments, other than short-term
      obligations, for the year ended December 31, 2006 were as follows:

      At December 31, 2006, two shareholders of record held in the aggregate
      approximately 49% of the total outstanding shares of the Fund. Investment
      activities of these shareholder could have a material impact on the Fund.

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

      At December 31, 2006 the Fund, for federal income tax purposes, has
      capital loss carryover of $47,356,671 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:

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

      During 2006, the Fund utilized $445,401 in capital loss carry forwards.
      Utilization of the capital loss carryovers above could be subject to
      limitations imposed by the Internal Revenue Code related to share
      ownership activity.

      The Fund elected to defer to its fiscal year ending December 31, 2007,
      $23,961 of capital losses and $470,274 of currency losses recognized
      during the period November 1, 2006 to December 31, 2006.

(6)   Financial Instruments:

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

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

      Options

      Call and put options give the holder the right to purchase or sell a
      security or currency or enter into a swap arrangement on a future date at
      a specified price. The Fund may use options to seek to hedge against risks
      of market exposure and changes in security prices and foreign currencies,
      as well as to seek to enhance returns. Writing puts and buying calls tend
      to increase the Fund's'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.

      For the year ended December 31, 2006, the Fund entered into the following
      transactions:

                                                Number of

                 Standish Mellon International Fixed Income Fund

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

      Forward currency exchange contracts

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

      At December 31, 2006, the Fund held forward 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, 2006, the Fund held open financial futures contracts. See
      the Schedule of Investments for further details.

      Swap agreements

      The Fund may enter into swap agreements. A swap is an agreement to
      exchange the return generated by one instrument for the return generated
      by another instrument. The Fund may enter into interest rate, credit
      default and total return swap agreements to manage its exposure to
      interest rates and credit risk. Interest rate swap agreements involve the
      exchange by the Fund with another party of their respective commitments to
      pay or receive interest, e.g., an exchange of floating rate payments for
      fixed rate payments with respect to a notional amount of principal. In a
      credit default swap, one party makes a stream of payments to another party
      in exchange for the right to receive a specified return in the event of a
      default by a third party on its obligation. The Fund may use credit
      default swaps to provide a measure of protection against defaults of
      issuers (i.e., to reduce risk where the Fund owns or has exposure to the
      corporate or sovereign issuer) or to take an active long or short position
      with respect to the likelihood of a particular corporate or sovereign
      issuer's default. Total return swap agreements involve commitments to pay
      interest in exchange for a market-linked return, both based on notional
      amounts. To the extent the total return of the security or index
      underlying the transaction exceeds or falls short of the offsetting
      interest rate obligation. The Fund will receive a payment from or make a
      payment to the counterparty. In connection with these agreements, cash or
      securities may be set aside as collateral in accordance with the terms of
      the swap agreement. The Fund earns interest on cash set aside as
      collateral. Swaps are marked to market daily based upon quotations, which
      may be furnished by a pricing service or dealers in such securities and
      the change in value, if any, is recorded as unrealized appreciation or
      depreciation in the Statement of Operations. These financial instruments
      are not actively traded on financial markets. The values assigned to these
      instruments are based upon the best available information and because of
      the uncertainty of the valuation, these values may differ significantly
      from the values that would have been realized had a ready market for these
      instruments existed, and differences could be material. Payments received
      or made at the beginning of the measurement period are reflected on the
      Statement of Assets and Liabilities. Payments received or made from credit
      default swaps at the end of the measurement period are recorded as
      realized gain or loss in the Statement of Operations. Net payments of
      interest on interest rate swap agreements, if any, are included as part of
      realized gain and loss. Entering into these agreements involves, to
      varying degrees, elements of credit, market, and documentation risk in
      excess of the amounts recognized in the Statement of Assets and
      Liabilities. Such risks involve the possibility that there will be no
      liquid market for these agreements, that the counterparty to the
      agreements may default on its obligation to perform or disagree as to the
      meaning of contractual terms in the agreements, and that there may be
      unfavorable changes in interest rates.

      At December 31, 2006, the Fund held open swap agreements. See the Schedule
      of Investments for further details.

(7)   Security Lending:

      The Fund may lend its securities to financial institutions which the Fund
      deems to be creditworthy. The loans are collateralized at all times with
      cash or securities with a market value at least equal to the market value
      of the securities on loan. The market value of securities loaned is
      determined daily and any additional required collateral is allocated to
      the Fund on the next business day. For the duration of a loan, the Fund
      receives the equivalent of the interest or dividends paid by the issuer on
      the securities loaned and also receives compensation from the investment
      of the collateral. As with other extensions of credit, the Fund bears the
      risk of delay in recovery or even loss of rights in its securities on loan
      should the borrower of the securities fail financially or default on its
      obligations to the Fund. In the event of borrower default, the Fund
      generally has the right to use the collateral to offset losses incurred.
      The Fund may incur a loss in the event it was delayed or prevented from
      exercising its rights to dispose of the collateral. The Fund 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, 2006 and
      earned interest on the invested collateral of $335,062 of which, $330,491
      was rebated to borrowers or paid in fees. At December 31, 2006, the Fund
      had securities valued at $299,852 on loan. See the Schedule of Investments
      for further detail on the security positions on loan and collateral held.

(8)   Line of Credit:

      The Fund, and other funds in the Trust and subtrusts in Mellon
      Institutional Funds Master Portfolio (the"Portfolio Trust") are parties to
      a committed line of credit facility, which enables each fund/portfolio to
      borrow, in the aggregate, up to $35 million. Interest is charged to each
      participating fund/portfolio based on its borrowings at a rate equal to
      the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility
      fee, computed at an annual rate of 0.060 of 1% on the committed amount, is
      allocated ratably among the participating funds/portfolios at the end of
      each quarter. The Fund/Portfolio also pays an annual renewal fee, computed
      at a rate of 0.020 of 1% of the committed amount and allocated ratably to
      the participating funds/portfolios. For the year ended December 31, 2006,
      the expense allocated to the Fund was $5,310. The commitment fee and
      interest expense are aggregated with miscellaneous expenses on the
      statement of operations.

      For the year ended December 31, 2006, the Fund had average borrowings
      outstanding of $2,336,733 for a total of fifteen days and incurred $5,657
      of interest expense. At December 31, 2006 the Fund had no borrowing
      outstanding.

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 present fairly, in all
material respects, the financial position of Standish Mellon International Fixed
Income Fund (the "Fund") at December 31, 2006, 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, 2006 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

     Factors Considered by Board of Trustees in Approving Advisory Agreement
                                   (Unaudited)
- --------------------------------------------------------------------------------

      The 1940 Act requires that the Board of Trustees, including a majority of
      its Trustees who are not affiliated with the fund's investment adviser or
      underwriter (the "Independent Trustees") voting separately, approve the
      fund's advisory agreement and the related fees on an annual basis. In
      their most recent deliberations concerning their decision to approve the
      continuation of the investment advisory agreement, the Board of Trustees
      conducted the review and made the determinations that are described below.
      In conducting this review and in making such determinations, the
      Independent Trustees received from the Fund's investment adviser, Standish
      Mellon Asset Management Company LLC ("Standish Mellon" or the "Adviser"),
      a broad range of information in response to a written request prepared on
      their behalf by their own legal counsel. The Independent Trustees met
      alone in a private session with their legal counsel on September 28, 2006
      to review these materials and to discuss the proposed continuation of the
      Fund's advisory agreement. Representatives of the Adviser attended a
      portion of the September meeting to provide an overview of its
      organization, personnel, resources and strategic plans, and to respond to
      questions and comments arising from the Independent Trustees' review of
      the materials and their deliberations. The entire Board then met on
      October 17, 2006.

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

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

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

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

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

      (v) Other Benefits: The benefits flowing to Mellon Financial Corporation
      ("Mellon") and its affiliates in the form of fees for transfer agency,
      custody, administration and securities lending services provided to the
      Funds by affiliates of 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 for at the September 28, 2006 Board meeting, the
      Trustees received similar detailed comparative performance information for
      the Fund at each regular Board meeting during the year.

      The Board considered the Fund's performance for the one-, three- and
      five-year periods ended July 31, 2006 based on the Lipper materials
      provided to the Board at the September 28, 2006 meeting. The Board found
      that the Fund outperformed its peer group average returns for the one-
      year period (2.23% vs. 1.87%), but underperformed its peer group average
      returns for the three-year period (3.98% vs. 5.40%) and five-year period
      (4.47% vs. 7.24%).

                 Standish Mellon International Fixed Income Fund

     Factors Considered by Board of Trustees in Approving Advisory Agreement
                                   (Unaudited)
- --------------------------------------------------------------------------------

      Advisory Fee and Other Expenses

      The Board considered the advisory fee rate paid by the Fund to the
      Adviser. The 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%, 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 0.485% (which included 0.084% in administrative
      services fees under Lipper's calculation methodology), below the peer
      group median net management fee of 0.495%. Based on the Lipper data, as
      well as other factors discussed at the September 28, 2006 meeting, the
      Board determined that the Fund's advisory fee is reasonable relative to
      its peer group averages.

      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 0.581% was lower than the median net expense ratio of the
      peer group of 0.73%, notwithstanding the fact that most of the other funds
      in the peer group were larger than the Fund.

      The Adviser's Profitability

      The Board considered the Adviser's profitability in managing the Fund and
      the Mellon Institutional Funds as a group, as well as the methodology used
      to compute such profitability, and the various direct and indirect
      expenses incurred by the Adviser or its affiliated investment adviser, The
      Boston Company Asset Management, LLC ("TBCAM") in managing the Fund and
      other funds in the Mellon Institutional Funds family of funds. The
      Independent Trustees had observed that the Adviser, based on the
      profitability information submitted to them by the Adviser, incurred
      losses in managing all but one of the investment companies in the Mellon
      Institutional Funds family of funds. The Trustees observed that Standish
      Mellon had experienced a slight profit in operating the Fund in 2004 and
      had incurred losses in operating the Fund in 2005.

      Economies of Scale

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

      Other Benefits

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

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

                                      * * *

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

February 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2006.

Financial markets showed substantial resilience in 2006, shrugging off concerns
that the slowdown in the housing market could drag the rest of the economy into
recession. The U.S. Federal Reserve (Fed) paused in its tightening cycle in
August, after 17 rate hikes since June 2004, as the Fed became convinced that
inflationary forces, and expectations, were under control. Perhaps the most
notable feature of this cycle is that the housing bubble is bursting at a time
when rates are not high. In previous cycles, housing market declines typically
follow a period of Fed tightenings that drive rates to extreme levels, choking
off credit, including mortgage financing. In this environment, credit for
housing and other sectors remains plentiful, with the housing pullback largely a
function of prices soaring beyond affordable levels for many prospective buyers.

The stock market climbed the proverbial "wall of worry" during 2006, with the
S&P 500 hitting new highs and providing a gain of 15.8%, including an 8.8%
advance in the fourth quarter. With U.S. monetary policy moderating, energy
prices in a swoon and the inflation threat receding, investors clearly feel that
the case for a soft landing is being reinforced.

In the bond markets, short-term rates advanced steadily, for the most part, in
cadence with the Fed's rate increases, with the 6-month Treasury bill ending the
year at 4.9%, up about 70 basis points. Rates on longer-term bonds increased to
a lesser degree, with the 10-year Treasury note ending about 30 basis points
higher at 4.7%. This produced an inverted yield curve, which is often a leading
indicator of recession.

Going forward, there is still much debate over the impact of the housing
downturn on the overall economy. We believe that the housing market is in for
prolonged weakness, because rates are already at relatively modest levels. Thus,
the boost provided by lower mortgage rates in the future is likely to be smaller
for housing than in it has been in previous cycles. However, there are other
bullish factors that should mitigate the drag of the housing market. As noted,
liquidity remains plentiful, and corporations are flush with cash. Spreads of
high yield bonds above Treasuries remain tight - an indicator that credit is
still available for riskier borrowers. High yield spreads tend to widen when the
market perceives a recession is likely.

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,

               Standish Mellon International Fixed Income Fund II

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

The first part of 2006 was a challenging environment for global bonds as G3
(U.S., Europe and Japan) 10-year yields rose 40 basis points. During the
remainder of the year, bonds rallied on weak economic data and a slowing housing
market.

The predominant drivers of G3 yields were the continued tightening by the U.S.
Federal Reserve (Fed) until July, as well as the steady diet of rate hikes from
the European Central Bank (ECB) and the Bank of Japan (BoJ). The BoJ tightening
cycle is truly groundbreaking as the zero interest rate policy ended and is a
signal that Japan is finally returning to sustainable economic growth.

This environment was made more challenging by significant reversals in the
direction of bond yields during 2006. The first half of 2006 saw global bond
yields rise, only to peak in June and then reverse direction for the remainder
of the year. Fortunately Standish Mellon International Fixed Income Fund II
(Fund) was well positioned to capture this shift in bond yields. The Fund was
short in duration at the start of 2006, yet after the Fed tightened interest
rates and the U.S. housing market displayed serious signs of weakness, the
Fund's holdings were reallocated to longer duration bonds to take advantage of a
potential drop in interest rates in the U.S. As the Fed held interest rates
steady in July, global bonds started a hesitant rally that carried yields of the
U.S. 10-year Treasury from 5.25% all the way down to 4.4% by November.

The tight correlation between global bond yields in 2006 saw European and
Japanese bond yields rally alongside U.S. yields in the second half of the year,
despite their central banks' rate hikes. U.S. bonds outperformed in the second
half, but for the year as a whole, Japanese bonds were the best performers,
followed by Canadian bonds.

The weak U.S. dollar helped the Fund produce relatively high returns compared to
other fixed income sectors. In November, the U.S. dollar began to slide relative
to the euro as investors reacted to the weaker outlook for the U.S., and the
bond market started to discount interest rate cuts by the Fed expected in 2007.
The dollar fell broadly, but the Japanese yen continues to be the funding
currency of choice, which has kept the currency on the weak and cheap.

The riskiest corners of the global bond markets, such as high yield and emerging
market debt, generated the highest absolute returns in 2006, and the 4th quarter
was no exception. Spread sectors were fair to rich, and as a result we
tactically reduced credit exposure of the Fund. However, if spreads widen, we
will welcome increased volatility and add credit and emerging exposure.

The Fund's 7.43% return outperformed its benchmark, the J.P. Morgan Non-U.S.
Government Bond Index (Unhedged), which returned 6.84% in 2006. Our global short
duration stance and slight extension, as yields peaked later in the year,
contributed to this positive performance during this period. Our country
positioning was also a significant contributor to positive performance as we
positioned the Fund to be overweight in U.S. bonds in the summer and short in
European and U.K. bonds for most of the year. Although we positioned the Fund to
have neutral exposure to Japanese bonds, which were the best performing, we were

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

"barbelled" in Japan and benefited as the yield curve flattened. The Fund's
allocation to emerging market bonds and exposure to high yield bonds, which
produced some of the best performance in all of fixed income, contributed
positively to Fund performance during the year. In addition, the Fund's
allocation to Polish local currency bonds performed well in the latter part of
2006 and continues to be a solid contributor.

Globally, bonds rallied early in the fourth quarter but sold off strongly in
December and our long duration exposure detracted from performance. We
anticipate global bonds to perform well in 2007 as economic growth slows and
inflation risks fade away.

During the year David Leduc replaced Charles Dolan as a co-portfolio manager of
the Fund. Thomas Fahey continues as the Fund's other co-portfolio manager.

We appreciate your continued investment in the Fund and look forward to working
on your behalf over the next year.

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund's dividend income and capital gains and
assuming a constant rate of performance each year. 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, 2006 to December 31, 2006).

Actual Expenses

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000=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 II

                          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 II Fund (the "Fund")
      is a separate diversified investment series of the Trust.

      The objective of the Fund is to maximize total return while realizing a
      market level of income consistent with preserving principal and liquidity.
      The Fund seeks to achieve its objective by investing, under normal
      circumstances, at least 80% of net assets in fixed income securities, and
      at least 65% of net assets in non-U.S. dollar denominated fixed income
      securities of foreign governments and companies located in various
      countries, including emerging markets.

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

      A. Investment security valuations

      Securities are valued at the last sale prices on the exchange or national
      securities market on which they are primarily traded. Securities not
      listed on an exchange or national securities market, or securities for
      which there were no reported transactions, are valued at the last quoted
      bid price. Securities that are fixed income securities, other than
      short-term instruments with less than sixty days remaining to maturity,
      for which 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.

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

      Short-term instruments with less than sixty days remaining to maturity are
      valued at amortized cost, which approximates market value. If the
      Portfolio acquires a short-term instrument with more than sixty days
      remaining to its maturity, it is valued at current market value until the
      sixtieth day prior to maturity and then is valued at amortized cost based
      upon the value on such date unless the Trustees determine during such
      sixty-day period that amortized cost does not represent fair value.

      B. Securities transactions and income

      Securities transactions are recorded as of the trade date. Interest income
      is determined on the basis of coupon interest earned, adjusted for
      accretion of discount or amortization of premium using the
      yield-to-maturity method on long-term debt securities and short-term
      securities with greater than sixty days to maturity. Dividend income is
      recorded on the ex-dividend date. Realized gains and losses from
      securities sold are recorded on the identified cost basis. 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 (loss) 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 a
      shareholder elects to receive them in cash.

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

                                       18



                   Mellon Institutional Funds Investment Trust
               Standish Mellon International Fixed Income Fund II

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

      Permanent book and tax basis differences relating to shareholder
      distributions will result in reclassifications among undistributed net
      investment income (loss), accumulated net realized gain (loss) and paid in
      capital. Undistributed net investment income (loss) and accumulated net
      realized gain (loss) on investments may include temporary book and tax
      basis differences which will reverse in a subsequent period. Any taxable
      income or gain remaining at fiscal year end is distributed in the
      following year.

      Section 988 of the Internal Revenue Code provides that gains or losses on
      certain transactions attributable to fluctuations in foreign currency
      exchange rates must be treated as ordinary income or loss. For financial
      statement purposes, such amounts are included in net realized gains or
      losses.

      D. Foreign currency transactions

      The Fund maintains its books and records in U.S. dollars. Investment
      security valuations, other assets, and liabilities initially expressed in
      foreign currencies are converted into U.S. dollars based upon current
      currency exchange rates. Purchases and sales of foreign investment
      securities and income and expenses are converted into U.S. dollars based
      upon currency exchange rates prevailing on the respective dates of such
      transactions.

      E. Foreign Investment risk

      There are certain additional risks involved in investing in foreign
      securities that are not inherent in investments in domestic securities.
      These risks may involve adverse political and economic developments,
      including the possible imposition of capital controls or other foreign
      governmental laws or restrictions. In addition, the securities of some
      foreign companies and securities markets are less liquid and at times may
      be more volatile than securities of comparable U.S. companies and U.S.
      securities markets. The risks described above apply to an even greater
      extent to investments in emerging markets. The securities markets of
      emerging countries are generally smaller, less developed, less liquid, and
      more volatile than the securities markets of the U.S. and developed
      foreign markets.

      F. Commitments and contingencies

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

      G. Expenses

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

      H. Affiliated issuers

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

      I. New Accounting Requirements

      In July 2006, the Financial Accounting Standards Board issued
      Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
      Interpretation of FASB Statement No. 109" (the "Interpretation"). The
      Interpretation establishes for all entities, including pass-through
      entities such as the Fund, a minimum threshold for financial statement
      recognition of the benefit of positions taken in filing tax returns
      (including whether an entity is taxable in a particular jurisdiction), and
      requires certain expanded tax disclosures. Adoption of FIN 48 is required
      for fiscal years beginning after December 15, 2006 and is to be applied to
      all open tax years as of the effective date. At this time, management is
      evaluating the implications of FIN 48 and its impact, if any, in the
      financial statements has not yet been determined.

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

      J. Federal Income 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.

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

      The investment advisory fee paid to Standish Mellon for overall investment
      advisory and administrative services, and general office facilities, is
      payable monthly at the annual rate of 0.40% of the Fund's average daily
      net assets. Standish Mellon voluntarily agreed to limit total Fund
      operating expenses (excluding brokerage commissions, taxes and
      extraordinary expenses) to 0.75% of the Fund's average daily net assets
      for year ended December 31, 2006. Pursuant to this agreement, for the year
      ended December 31, 2006, Standish Mellon voluntarily waived a portion of
      its investment advisory fee in the amount of $80,235. This agreement is
      voluntary and temporary and may be discontinued or revised by Standish
      Mellon at any time.

      On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
      New York Company, Inc. ("BNY") announced that they had entered into a
      definitive agreement to merge. The new company will be called The Bank of
      New York Mellon Corporation. As part of this transaction, Standish Mellon
      would become an indirect wholly-owned subsidiary of The Bank of New York
      Mellon Corporation. The transaction is subject to certain regulatory
      approvals and the approval of BNY's and MFC's shareholders, as well as
      other customary conditions to closing. Subject to such approvals and the
      satisfaction of the other conditions, MFC and BNY expect the transaction
      to be completed in the third quarter of 2007.

      The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly
      owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of
      Mellon Financial Corporation and an affiliate of Standish Mellon, to
      provide personnel and facilities to perform transfer agency and certain
      shareholder services for the Fund. For these services, the Fund pays
      Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based
      fees, as well as, out-of-pocket expenses. Pursuant to this agreement the
      Fund was charged $7,106, for the year ended December 31, 2006.

      The Trust has entered into an agreement with Mellon Bank, N.A. ("Mellon
      Bank"), a wholly owned subsidiary of Mellon Financial Corporation and an
      affiliate of Standish Mellon, to provide custody, administration and fund
      accounting services for the Fund. For these services the Fund pays Mellon
      Bank a fixed fee plus asset and transaction based fees, as well as
      out-of-pocket expenses. Pursuant to this agreement the Fund was charged
      $92,640 during the year ended December 31, 2006.

      The Trust also entered into an agreement with Mellon Bank to perform
      certain securities lending activities and to act as the Fund's lending
      agent. Mellon Bank receives an agreed upon percentage of the net lending
      revenues. Pursuant to this agreement, Mellon Bank earned $1,096 for the
      year ended December 31, 2006. See Note 7 for further details.

      The Trust reimburses Mellon Asset Management for a portion of the salary
      of the Trust's Chief Compliance Officer. For the year ended December 31,
      2006, the Fund was charged $4,029. 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 Mellon Financial Corporation and an affiliate of Standish
      Mellon, to provide printing and fulfillment services for the Fund.
      Pursuant to this agreement the Fund was charged $6,185 for the year ended
      December 31, 2006.

      The Fund pays administrative service fees. These fees are paid to
      affiliated or unaffiliated retirement plans, omnibus accounts and platform
      administrators and other entities ("Plan Administrators") that provide
      record keeping and/or other administrative support services to accounts,
      retirement plans and their participants. As compensation for such
      services, the Fund may pay each Plan Administrator an administrative
      service fee in an amount of up to 0.15% (on an annualized basis) of the
      Fund's average daily net assets attributable to Fund shares that are held
      in accounts serviced by such Plan Administrator. The Fund's adviser or its
      affiliates may pay additional compensation from their own resources to
      Plan Administrators and other entities for administrative services, as
      well as in consideration of marketing or other distribution-related
      services. These payments may provide an incentive for these entities to
      actively promote the Fund or cooperate with the distributor's promotional
      efforts. For the year ended December 31, 2006, the Fund was charged $4,873
      for fees payable to Mellon Private Wealth Management.

      At December 31, 2006, one shareholder of record held approximately 60% of
      the total outstanding shares of the Fund. Investment activity of this
      shareholder could have a material impact on the Fund.

      The Fund imposes a redemption fee of 2% of the net asset value of the
      shares, with certain exceptions, which are redeemed or exchanged less than
      30 days from the day of their purchase. The redemption fee is paid
      directly to the Fund, and is designed to offset brokerage commissions,
      market impact, and other costs associated with short-term trading in the
      Fund. The fee does not apply to shares that were acquired through
      reinvestment of distributions. For the year ended December 31, 2006, the
      Fund received $401 in redemption fees.

(6)   Financial Instruments:

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

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

      Options

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

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

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

      For the year ended December 31, 2006, the Fund entered into the following
      transactions:

                                                Number of
            Written Put Option Transactions     Contracts   Premiums

      Forward currency exchange contracts

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

      At December 31, 2006, the Fund held forward 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/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, 2006, 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 gain or loss in the
      Statement of Operations. These financial instruments are not actively
      traded on financial markets. The values assigned to these instruments are
      based upon the best available information and because of the uncertainty
      of the valuation, these values may differ significantly from the values
      that would have been realized had a ready market for these instruments
      existed, and differences could be material. Payments received or made at
      the beginning of the measurement period are reflected as such on the
      Statement of Assets and Liabilities.

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

      Payments received or made from credit default swaps at the end of the
      measurement period are recorded as realized appreciation/depreciation in
      the Statement of Operations. Net payments of interest on interest rate
      swap agreements, if any, are included as part of realized gain and loss.
      Entering into these agreements involves, to varying degrees, elements of
      credit, market, and documentation risk in excess of the amounts recognized
      in the Statement of Assets and Liabilities. Such risks involve the
      possibility that there will be no liquid market for these agreements, that
      the counterparty to the agreements may default on its obligation to
      perform or disagree as to the meaning of contractual terms in the
      agreements, and that there may be unfavorable changes in interest rates.

      At December 31, 2006, the Fund held open swap agreements. See the Schedule
      of Investments for further details.

(7)   Security Lending:

      The Fund may lend its securities to financial institutions which the Fund
      deems to be creditworthy. The loans are collateralized at all times with
      cash or securities with a market value at least equal to the market value
      of the securities on loan. The market value of securities loaned is
      determined daily and any additional required collateral is allocated to
      the Fund on the next business day. For the duration of a loan, the Fund
      receives the equivalent of the interest or dividends paid by the issuer on
      the securities loaned and also receives compensation from the investment
      of the collateral. As with other extensions of credit, the Fund bears the
      risk of delay in recovery or even loss of rights in its securities on loan
      should the borrower of the securities fail financially or default on its
      obligations to the Fund. In the event of borrower default, the Fund
      generally has the right to use the collateral to offset losses incurred.
      The Fund may incur a loss in the event it was delayed or prevented from
      exercising its rights to dispose of the collateral. The Fund 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, 2006 and
      earned interest on the invested collateral of $109,554 of which, $106,982
      was rebated to borrowers or paid in fees. At December 31, 2006, the Fund
      had securities valued at $80,611 on loan. See the Schedule of Investments
      for further detail on the security positions on loan and collateral held.

(8)   Line of Credit:

      The Fund, and other funds in the Trust and subtrusts in Mellon
      Institutional Funds Master Portfolio (the"Portfolio Trust") are parties to
      a committed line of credit facility, which enables each fund/portfolio to
      borrow, in the aggregate, up to $35 million. Interest is charged to each
      participating fund/portfolio based on its borrowings at a rate equal to
      the Federal Funds effective rate plus 1/2 of 1%. In addition, a facility
      fee, computed at an annual rate of 0.060 of 1% on the committed amount, is
      allocated ratably among the participating funds/portfolios at the end of
      each quarter. The Fund/Portfolio also pays an annual renewal fee, computed
      at a rate of 0.020 of 1% of the committed amount and allocated ratably to
      the participating funds/portfolios. For the year ended December 31, 2006,
      the expense allocated to the Fund was $1,832. The facility fee and
      interest expense are included in miscellaneous expenses on the statement
      of operations.

      For the year ended December 31, 2006, the Fund had average borrowings
      outstanding of $1,040,444 for a total of nine days and incurred $1,369 of
      interest expense. At December 31, 2006 the Fund had no borrowings
      outstanding.

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

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

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 present fairly, in all
material respects, the financial position of Standish Mellon International Fixed
Income Fund II (the "Fund") at December 31, 2006, 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, 2006 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 II

     Factors Considered by Board of Trustees in Approving Advisory Agreement
                                   (Unaudited)
- --------------------------------------------------------------------------------

      The 1940 Act requires that the Board of Trustees, including a majority of
      its Trustees who are not affiliated with the fund's investment adviser or
      underwriter (the "Independent Trustees") voting separately, approve the
      fund's advisory agreement and the related fees on an annual basis. In
      their most recent deliberations concerning their decision to approve the
      continuation of the investment advisory agreement, the Board of Trustees
      conducted the review and made the determinations that are described below.
      In conducting this review and in making such determinations, the
      Independent Trustees received from the Fund's investment adviser, Standish
      Mellon Asset Management Company LLC ("Standish Mellon" or the "Adviser"),
      a broad range of information in response to a written request prepared on
      their behalf by their own legal counsel. The Independent Trustees met
      alone in a private session with their legal counsel on September 28, 2006
      to review these materials and to discuss the proposed continuation of the
      Fund's advisory agreement. Representatives of the Adviser attended a
      portion of the September meeting to provide an overview of its
      organization, personnel, resources and strategic plans, and to respond to
      questions and comments arising from the Independent Trustees' review of
      the materials and their deliberations. The entire Board then met on
      October 17, 2006.

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

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

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

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

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

      (v) Other Benefits: The benefits flowing to Mellon Financial Corporation
      ("Mellon") and its affiliates in the form of fees for transfer agency,
      custody, administration and securities lending services provided to the
      Funds by affiliates of 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 for at the September 28, 2006 Board meeting, the
      Trustees received similar detailed comparative performance information for
      the Fund at each regular Board meeting during the year.

      The Board considered the Fund's performance for the one-, three- and
      five-year periods ended July 31, 2006 based on the Lipper materials
      provided to the Board at the September 28, 2006 meeting. The Board found
      that the Fund outperformed its peer group average returns for the one-year
      period (1.55% vs. 0.80%), but underperformed its peer group average
      returns for the three-year period (5.81% vs. 5.93%) and five-year period
      (8.99% vs. 9.53%).

                   Mellon Institutional Funds Investment Trust
               Standish Mellon International Fixed Income Fund II

    Factors Considered by Board of Trustees in Approving Advisory Agreement
                                  (Unaudited)
- --------------------------------------------------------------------------------

      Advisory Fee and Other Expenses

      The Board considered the advisory fee rate paid by the Fund to the
      Adviser. The 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%, in the 1st (best) quintile
      of its peer group of funds, the median fee of which was 0.62%. The Fund's
      net management fee, after giving effect to expense limitations, was 0.293%
      (which included no administrative services fees under Lipper's calculation
      methodology), well 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 28, 2006 meeting, the Board determined that the Fund's
      advisory fee is reasonable relative to its peer group averages, both with
      and without giving effect to expense limitations.

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

      The Board also considered the Fund's expense ratio and compared it to that
      of its peer group of similar funds. The Board found that the actual net
      expense ratio of 0.75% (after giving effect to expense limitations) was
      lower than the median net expense ratio of the peer group of 0.80%
      notwithstanding the fact that all of the other funds in the peer group
      were larger than the Fund.

      The Adviser's Profitability

      The Board considered the Adviser's profitability in managing the Fund and
      the Mellon Institutional Funds as a group, as well as the methodology used
      to compute such profitability, and the various direct and indirect
      expenses incurred by the Adviser or its affiliated investment adviser, The
      Boston Company Asset Management, LLC ("TBCAM") in managing the Fund and
      other funds in the Mellon Institutional Funds family of funds. The
      Independent Trustees had observed that the Adviser, based on the
      profitability information submitted to them by the Adviser, incurred
      losses in managing all but one of the investment companies in the Mellon
      Institutional Funds family of funds. The Trustees observed that Standish
      Mellon had incurred losses in operating the Fund in both 2004 and 2005.

      Economies of Scale

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

      Other Benefits

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

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

                                      * * *

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

February 2007

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2006.

Financial markets showed substantial resilience in 2006, shrugging off concerns
that the slowdown in the housing market could drag the rest of the economy into
recession. The U.S. Federal Reserve (Fed) paused in its tightening cycle in
August, after 17 rate hikes since June 2004, as the Fed became convinced that
inflationary forces, and expectations, were under control. Perhaps the most
notable feature of this cycle is that the housing bubble is bursting at a time
when rates are not high. In previous cycles, housing market declines typically
follow a period of Fed tightenings that drive rates to extreme levels, choking
off credit, including mortgage financing. In this environment, credit for
housing and other sectors remains plentiful, with the housing pullback largely a
function of prices soaring beyond affordable levels for many prospective buyers.

The stock market climbed the proverbial "wall of worry" during 2006, with the
S&P 500 hitting new highs and providing a gain of 15.8%, including an 8.8%
advance in the fourth quarter. With U.S. monetary policy moderating, energy
prices in a swoon and the inflation threat receding, investors clearly feel that
the case for a soft landing is being reinforced.

In the bond markets, short-term rates advanced steadily, for the most part, in
cadence with the Fed's rate increases, with the 6-month Treasury bill ending the
year at 4.9%, up about 70 basis points. Rates on longer-term bonds increased to
a lesser degree, with the 10-year Treasury note ending about 30 basis points
higher at 4.7%. This produced an inverted yield curve, which is often a leading
indicator of recession.

Going forward, there is still much debate over the impact of the housing
downturn on the overall economy. We believe that the housing market is in for
prolonged weakness, because rates are already at relatively modest levels. Thus,
the boost provided by lower mortgage rates in the future is likely to be smaller
for housing than in it has been in previous cycles. However, there are other
bullish factors that should mitigate the drag of the housing market. As noted,
liquidity remains plentiful, and corporations are flush with cash. Spreads of
high yield bonds above Treasuries remain tight - an indicator that credit is
still available for riskier borrowers. High yield spreads tend to widen when the
market perceives a recession is likely.

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,

/s/ Patrick J. Sheppard

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

The first part of 2006 was a challenging environment for global bonds as G3
(U.S., Europe and Japan) 10-year yields rose 40 basis points. During the
remainder of the year, bonds rallied on weak economic data and a slowing housing
market.

The predominant drivers of G3 yields were the continued tightening by the U.S.
Federal Reserve (Fed) until July, as well as the steady diet of rate hikes from
the European Central Bank (ECB) and the Bank of Japan (BoJ). The BoJ tightening
cycle is truly groundbreaking as the zero interest rate policy ended and is a
signal that Japan is finally returning to sustainable economic growth.

This environment was made more challenging by significant reversals in the
direction of bond yields during 2006. The first half of 2006 saw global bond
yields rise, only to peak in June and then reverse direction for the remainder
of the year. Fortunately, the Standish Mellon Global Fixed Income Fund (Fund)
was well positioned to capture this shift in bond yields. The Fund was short in
duration at the start of 2006, yet after the Fed tightened interest rates and
the U.S. housing market displayed serious signs of weakness, the Fund's holdings
were reallocated to longer duration bonds to take advantage of a potential drop
in interest rates in the U.S. As the Fed held interest rates steady in July,
global bonds started a hesitant rally that carried yields of the U.S. 10-year
Treasury from 5.25% all the way down to 4.4% by November.

The tight correlation between global bond yields in 2006 saw European and
Japanese bond yields rally alongside U.S. yields in the second half of the year,
despite their central banks' rate hikes. U.S. bonds outperformed in the second
half, but for the year as a whole, Japanese bonds were the best performers,
followed by Canadian bonds.

In November, the U.S. dollar began to slide relative to the euro as investors
reacted to the weaker outlook for the U.S., and the bond market started to
discount interest rate cuts expected by the Fed in 2007. The dollar fell
broadly, but the Japanese yen continues to be the funding currency of choice,
which kept the currency on the weak and cheap.

The riskiest corners of the global bond markets, such as high yield and emerging
market debt, generated the highest absolute returns in 2006, and the 4th quarter
was no exception. Spread sectors were fair to rich, and as a result we
tactically reduced credit exposure of the Fund. However, if spreads widen, we
will welcome increased volatility and add credit and emerging exposure.

The Fund's 5.09% return outperformed its benchmark, the Lehman Brothers Global
Aggregate U.S. Hedged Index, which returned 3.64% in 2006. Our global short
duration stance and slight extension, as yields peaked later in the year,
contributed to this positive performance during this period. Our country
positioning was also a significant contributor to positive performance as we
positioned the Fund to be overweight in U.S. bonds in the summer and short in
European and U.K. bonds for most of the year. Although we positioned the Fund to
have neutral exposure to Japanese bonds, which were the best performing, we were
"barbelled" in

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

Japan and benefited as the yield curve flattened. The Fund's allocation to
emerging market bonds and exposure to high yield bonds, which produced some of
the best performance in all of fixed income, contributed positively to Fund
performance during the year. In addition, the Fund's allocation to Polish local
currency bonds performed well in the latter part of 2006 and continues to be a
solid contributor.

Globally, bonds rallied early in the fourth quarter but sold off strongly in
December and our long duration exposure detracted from performance. However, we
anticipate global bonds to perform well in 2007 as economic growth slows and
inflation risks fade away.

During the year David Leduc replaced Charles Dolan as a co-portfolio manager of
the Fund. Thomas Fahey continues as the Fund's other co-portfolio manager.

We appreciate your continued investment in the Fund and look forward to working
on your behalf over the next year.

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, 2006 to December 31, 2006).

Actual Expenses

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000=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 object of the Fund is to maximize total return while realizing a
      market level of income consistent with preserving principal and liquidity.
      The Fund invests all its investable assets in an interest of Standish
      Mellon Global Fixed Income Portfolio (the "Portfolio"), a subtrust of
      Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which
      is organized as a New York trust and has the same investment objective as
      the Fund. The Portfolio seeks to achieve its objective by investing, under
      normal circumstances, at least 80% of its net assets in U.S. dollar and
      non-U.S. dollar denominated fixed income securities of governments and
      companies located in various countries, including emerging markets. The
      value of the Fund's investment in the Portfolio reflects the Fund's
      proportionate interest in the net assets of the Portfolio (100% at
      December 31, 2006). The performance of the Fund is directly affected by
      the performance of the Portfolio. The financial statements of the
      Portfolio are included elsewhere in this report and should be read in
      conjunction with the Fund's financial statements.

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

      A. Investment security valuations

      Fund shares are valued as of the close of regular trading (normally 4:00
      p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
      is open. The Fund records its investment in the Portfolio at value. The
      Portfolio values its securities at value as discussed in Note 1A of the
      Portfolio's Notes to Financial Statements, which are included elsewhere in
      this report.

      B. Securities transactions and income

      The Fund's investment in the Portfolio is recorded on settlement date. The
      Portfolio's securities transactions are recorded as of the trade date as
      discussed in Note 1B of the Portfolio's Notes to Financial Statements,
      which are included elsewhere in the report. Currently, the Fund's net
      investment income consists of the Fund's pro rata share of the net
      investment income of the Portfolio, less all expenses of the Fund
      determined in accordance with accounting principles generally accepted in
      the United States of America. All realized and unrealized gains and losses
      of the Fund represent pro rata shares of gains and losses of the
      Portfolio.

      C. Distributions to shareholders

      Distributions to shareholders are recorded on the ex-dividend date. The
      Fund's distributions from capital gains, if any, after reduction of
      capital losses are declared and distributed at least annually. In
      determining the amounts of its dividends, the Fund will take into account
      its share of the income, gains or losses, expenses, and any other tax
      items of the Portfolio. Dividends from net investment income and
      distributions from capital gains, if any, are reinvested in additional
      shares of the Fund unless a shareholder elects to receive them in cash.

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

      Permanent book and tax basis differences relating to shareholder
      distributions will result in reclassifications among undistributed net
      investment income(loss), accumulated net realized gain (loss) and paid in
      capital. Undistributed net investment income (loss) and accumulated net
      realized gain (loss) on investments may include temporary book and tax
      basis differences which will reverse in a subsequent period. Any taxable
      income or gain remaining at fiscal year end is distributed in the
      following year.

      D. Expenses

      The majority of expenses of the Trust or Portfolio Trust are directly
      identifiable to an individual fund or portfolio. Expenses which are not
      readily identifiable to a specific fund or portfolio are allocated among
      funds of the Trust and/or portfolios of the Portfolio Trust taking into
      consideration, among other things, the nature and type of expense and the
      relative size of the funds or portfolios.

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

      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. Federal Income 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.

      G. New Accounting Requirements

      In July 2006, the Financial Accounting Standards Board issued
      Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
      Interpretation of FASB Statement No. 109" (the "Interpretation"). The
      Interpretation establishes for all entities, including pass-through
      entities such as the Portfolio, a minimum threshold for financial
      statement recognition of the benefit of positions taken in filing tax
      returns (including whether an entity is taxable in a particular
      jurisdiction), and requires certain expanded tax disclosures. Adoption of
      FIN 48 is required for fiscal years beginning after December 15, 2006 and
      is to be applied to all open tax years as of the effective date. At this
      time, management is evaluating the implications of FIN 48 and its impact,
      if any, in the financial statements has not yet been determined.

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

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

      The Fund does not directly pay any investment advisory fees, but
      indirectly bears its pro rata share of the compensation paid by the
      Portfolio to Standish Mellon Asset Management Company LLC ("Standish
      Mellon"), a wholly-owned subsidiary of Mellon Financial Corporation, for
      such services. See Note 2 of the Portfolio's Notes to Financial Statements
      which are included elsewhere in this report. Standish Mellon voluntarily
      agreed to limit the total operating expenses of the Fund and its pro rata
      share of the Portfolio expenses (excluding brokerage commissions, taxes
      and extraordinary expenses) to 0.65% of the Fund's average daily net
      assets. Pursuant to this agreement, for the year ended December 31, 2006,
      Standish Mellon voluntarily reimbursed the Fund for $73,320 of its
      operating expenses. This agreement is voluntary and temporary and may be
      discontinued or revised by Standish Mellon at any time.

      On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
      New York Company, Inc. ("BNY") announced that they had entered into a
      definitive agreement to merge. The new company will be called The Bank of
      New York Mellon Corporation. As part of this transaction, Standish Mellon
      would become an indirect wholly-owned subsidiary of The Bank of New York
      Mellon Corporation. The transaction is subject to certain regulatory
      approvals and the approval of BNY's and MFC's shareholders, as well as
      other customary conditions to closing. Subject to such approvals and the
      satisfaction of the other conditions, MFC and BNY expect the transaction
      to be completed in the third quarter of 2007.

      The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly
      owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of
      Mellon Financial Corporation and an affiliate of Standish Mellon, to
      provide personnel and facilities to perform transfer agency and certain
      shareholder services for the Fund. For these services, the Fund pays
      Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based
      fees, as well as, out-of-pocket expenses. Pursuant to this agreement the
      Fund was charged $6,551, for the year ended December 31, 2006.

      The Trust has contracted Mellon Investor Services LLC, a wholly owned
      subsidiary of Mellon Financial Corporation and an affiliate of Standish
      Mellon, to provide printing and fulfillment services for the Fund.
      Pursuant to this agreement, the Fund was charged $3,330 for the year ended
      December 31, 2006.

      The Trust reimburses Mellon Asset Management for a portion of the salary
      of the Trust's Chief Compliance Officer. For the year ended December 31,
      2006, the Fund was charged $4,030. No other director, officer or employee
      of Standish Mellon or its affiliates receives any compensation from the
      Trust or the Portfolio Trust for serving as an officer or Trustee of the
      Trust. The Fund pays each Trustee who is not a director, officer or
      employee of Standish Mellon or its affiliates an annual fee.

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

      The Fund pays administrative service fees. These fees are paid to
      affiliated or unaffiliated retirement plans, omnibus accounts and platform
      administrators and other entities ("Plan Administrators") that provide
      record keeping and/or other administrative support services to accounts,
      retirement plans and their participants. As compensation for such
      services, the Fund may pay each Plan Administrator an administrative
      service fee in an amount of up to 0.15% (on an annualized basis) of the
      Fund's average daily net assets attributable to Fund shares that are held
      in accounts serviced by such Plan Administrator. The Fund's adviser or its
      affiliates may pay additional compensation from their own resources to
      Plan Administrators and other entities for administrative services, as
      well as in consideration of marketing or other distribution-related
      services. These payments may provide an incentive for these entities to
      actively promote the Fund or cooperate with the distributor's promotional
      efforts. For the year ended December 31, 2006, the Fund was charged $515
      for fees payable to Mellon Private Wealth Management.

(3)   Investment Transactions:

      Increases and decreases in the Fund's investment in the Portfolio for the
      year ended December 31, 2006, aggregated $3,466,361 and $28,847,433,
      respectively. The Fund receives a proportionate share of the Portfolio's
      income, expenses, and realized and unrealized gains and losses based on
      applicable tax allocation rules.

(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, 2006, one shareholder of record held approximately 77% of
      the total outstanding shares of the Fund. Investment activity of this
      shareholder could have a material impact on the Fund.

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

(5)   Federal Taxes:

      As of December 31, 2006, the components of distributable earnings on a tax
      basis were as follows:

               Undistributed ordinary income      $            --
               Undistributed capital gains                     --

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

      At December 31, 2006, 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:

      $345,037 of capital losses and $250,757 of currency losses recognized
      during the period November 1, 2006 to December 31, 2006.

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

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

In our opinion, the accompanying statement of assets and liabilities, and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Standish Mellon Global Fixed Income Fund (the "Fund") at December 31, 2006, 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 agreement of the amount of the investment in the Standish
Mellon Global Fixed Income Portfolio (the "Portfolio") at December 31, 2006 to
the Portfolio's records, provide a reasonable basis for our opinion.

(1)   Organization and Significant Accounting Policies:

      Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
      organized as a master trust fund under the laws of the State of New York
      on January 18, 1996 and is registered under the Investment Company Act of
      1940, as amended, as an open-end, management investment company. Standish
      Mellon Global Fixed Income Portfolio (the "Portfolio") is a separate
      non-diversified investment series of the Portfolio Trust.

      The objective of the Portfolio is to maximize total return while realizing
      a market level of income consistent with preserving principal and
      liquidity. The Portfolio seeks to achieve its objective by investing,
      under normal circumstances, at least 80% of its net assets in U.S. dollar
      and non-U.S. dollar denominated fixed income securities of governments and
      companies located in various countries, including emerging markets.

      At December 31, 2006 there was one fund, Standish Mellon Global Fixed
      Income Fund (the "Fund"), invested in the Portfolio. The value of the
      Fund's investment in the Portfolio reflects the Fund's proportionate
      interest in the net assets of the Portfolio. The Fund's proportionate
      interest at December 31, 2006 was 100%.

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

      A. Investment security valuations

      Securities are valued at the last sale prices on the exchange or national
      securities market on which they are primarily traded. Securities not
      listed on an exchange or national securities market, or securities for
      which there were no reported transactions, are valued at the last quoted
      bid price. Securities that are fixed income securities, other than
      short-term instruments with less than sixty days remaining to maturity,
      for which 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.

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

      Short-term instruments with less than sixty days remaining to maturity are
      valued at amortized cost, which approximates market value. If the
      Portfolio acquires a short-term instrument with more than sixty days
      remaining to its maturity, it is valued at current market value until the
      sixtieth day prior to maturity and then is valued at amortized cost based
      upon the value on such date unless the Trustees determine during such
      sixty-day period that amortized cost does not represent fair value.

      B. Securities transactions and income

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

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

      C. Income taxes

      The Portfolio is treated as a disregarded entity for federal tax purposes.
      No provision is made by the Portfolio for federal or state income taxes on
      any taxable income of the Portfolio because each investor in the Portfolio
      is ultimately responsible for the payment of any taxes. Since the
      Portfolio's investor is a regulated investment company that invests all or
      substantially all of its assets in the Portfolio, the Portfolio normally
      must satisfy the source of income and diversification requirements
      applicable to regulated investment companies (under the Internal Revenue
      Code) in order for its investors to satisfy them.

      Section 988 of the Internal Revenue Code provides that gains or losses on
      certain transactions attributable to fluctuations in foreign currency
      exchange rates must be treated as ordinary income or loss. For financial
      statement purposes, such amounts are included in net realized gains or
      losses.

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

      D. Foreign currency transactions

      The Portfolio maintains its books and records in U.S. dollars. Investment
      security valuations, other assets, and liabilities initially expressed in
      foreign currencies are converted into U.S. dollars based upon current
      currency exchange rates. Purchases and sales of foreign investment
      securities and income and expenses are converted into U.S. dollars based
      upon currency exchange rates prevailing on the respective dates of such
      transactions.

      E. Foreign Investment risk

      There are certain additional risks involved in investing in foreign
      securities that are not inherent in investments in domestic securities.
      These risks may involve adverse political and economic developments,
      including the possible imposition of capital controls or other foreign
      governmental laws or restrictions. In addition, the securities of some
      foreign companies and securities markets are less liquid and at times may
      be more volatile than securities of comparable U.S. companies and U.S.
      securities markets. The risks described above apply to an even greater
      extent to investments in emerging markets. The securities markets of
      emerging countries are generally smaller, less developed, less liquid, and
      more volatile than the securities markets of the U.S. and developed
      foreign markets.

      F. Commitments and contingencies

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

      G. Expenses

      The majority of expenses of the Trust or Portfolio Trust are directly
      identifiable to an individual fund or portfolio. Expenses which are not
      readily identifiable to a specific fund or portfolio are allocated among
      funds of the Trust or portfolios of the Portfolio Trust taking into
      consideration, among other things, the nature and type of expense and the
      relative size of the funds or portfolios.

      H. Affiliated issuers

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

      I. New Accounting Requirements

      In July 2006, the Financial Accounting Standards Board issued
      Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
      Interpretation of FASB Statement No. 109" (the "Interpretation"). The
      Interpretation establishes for all entities, including pass-through
      entities such as the Portfolio, a minimum threshold for financial
      statement recognition of the benefit of positions taken in filing tax
      returns (including whether an entity is taxable in a particular
      jurisdiction), and requires certain expanded tax disclosures. Adoption of
      FIN 48 is required for fiscal years beginning after December 15, 2006 and
      is to be applied to all open tax years as of the effective date. At this
      time, management is evaluating the implications of FIN 48 and its impact,
      if any, in the financial statements has not yet been determined.

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

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

      The investment advisory fee paid to Standish Mellon for overall investment
      advisory, administrative services, and general office facilities is paid
      monthly at the annual rate of 0.40% of the Portfolio's average daily net
      assets. Standish Mellon voluntarily agreed to limit the total operating
      expenses of the Fund and it's pro rata share of the Portfolio expenses
      (excluding commissions, taxes and extraordinary expenses) to 0.65% of the
      Fund's average daily net assets. Pursuant to this agreement, for the year
      ended December 31, 2006, Standish Mellon voluntarily waived a portion of
      its investment advisory fee in the amount of $23,303. This agreement is
      voluntary and temporary and may be discontinued or revised by Standish
      Mellon at any time.

      On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
      New York Company, Inc. ("BNY") announced that they had entered into a
      definitive agreement to merge. The new company will be called The Bank of
      New York Mellon Corporation. As part of this transaction, Standish Mellon
      would become an indirect wholly-owned subsidiary of The Bank of New York
      Mellon Corporation. The transaction is subject to certain regulatory
      approvals and the approval of BNY's and MFC's shareholders, as well as
      other customary conditions to closing. Subject to such approvals and the
      satisfaction of the other conditions, MFC and BNY expect the transaction
      to be completed in the third quarter of 2007.

      The Portfolio Trust has entered into an agreement with Mellon Bank, N.A.
      ("Mellon Bank"), a wholly owned subsidiary of Mellon Financial Corporation
      and an affiliate of Standish Mellon, to provide custody, administration
      and fund accounting services for the Portfolio. For these services the
      Portfolio pays Mellon Bank a fixed fee plus asset and transaction based
      fees, as well as out-of-pocket expenses. Pursuant to this agreement the
      Portfolio was charged $104,056 during the year ended December 31, 2006.

      The Portfolio Trust also entered into an agreement with Mellon Bank to
      perform certain securities lending activities and to act as the
      Portfolio's lending agent. Mellon Bank receives an agreed upon percentage
      of the net lending revenues. Pursuant to this agreement, Mellon Bank
      earned $3,437 for the year ended December 31, 2006. See Note 6 for further
      details.

      The Trust reimburses Mellon Asset Management for a portion of the salary
      of the Trust's and Portfolio Trust's Chief Compliance Officer. No other
      director, officer or employee of Standish Mellon or its affiliates
      received any compensation from the Trust or the Portfolio Trust for
      serving as an officer or Trustee of the Trust or the Portfolio Trust. The
      Fund and Portfolio Trust pays each Trustee who is not a director, officer
      or employee of Standish Mellon or its affiliates (the "Independent
      Trustees") an annual fee and the Portfolio Trust pays each Independent
      Trustee a per meeting fee as well as reimbursement for travel and out of
      pocket expenses. In addition, the Portfolio Trust pays the legal fees for
      the counsel to the Independent Trustees.

(3)   Purchases and Sales of Investments:

      Purchases and proceeds from sales of investments, other than short-term
      obligations, for the year ended December 31, 2006 were as follows:

                                                    Purchases          Sales

(5)   Financial Instruments:

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

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

      Options

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

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

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

      For the year ended December 31, 2006, the Portfolio transactions in
      options were as follows:

                                               Number of
            Written Put Option Transactions    Contracts    Premiums
                                               ---------    --------

            Options expired                           (8)    (43,366)

            Outstanding, end of period                --    $     --

                                               ---------    --------
            Outstanding, beginning of period           1    $  6,958
            Options written                            3      29,084
            Options expired                           (3)    (31,418)
            Options closed                            (1)     (4,624)
                                               ---------    --------
            Outstanding, end of period                --    $     --
                                               =========    ========

      At December 31, 2006, the Portfolio had no written options outstanding.

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

      Forward currency exchange contracts

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

      At December 31, 2006, the Portfolio held forward currency exchange
      contracts. See the Schedule of Investments for further details.

      Futures contracts

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

      At December 31, 2006, the Portfolio held open financial futures contracts.
      See the Schedule of Investments for further details.

      Swap agreements

      The Portfolio may enter into swap agreements. A swap is an agreement to
      exchange the return generated by one instrument for the return generated
      by another instrument. The Portfolio may enter into interest rate, credit
      default and total return swap agreements to manage its exposure to
      interest rates and credit risk. Interest rate swap agreements involve the
      exchange by the Portfolio with another party of their respective
      commitments to pay or receive interest, e.g., an exchange of floating rate
      payments for fixed rate payments with respect to a notional amount of
      principal. In a credit default swap, one party makes a stream of payments
      to another party in exchange for the right to receive a specified return
      in the event of a default by a third party on its obligation. The
      Portfolio may use credit default swaps to provide a measure of protection
      against defaults of issuers (i.e., to reduce risk where the Portfolio owns
      or has exposure to the corporate or sovereign issuer) or to take an active
      long or short position with respect to the likelihood of a particular
      corporate or sovereign issuer's default. Total return swap agreements
      involve commitments to pay interest in exchange for a market-linked
      return, both based on notional amounts. To the extent the total return of
      the security or index underlying the transaction exceeds or falls short of
      the offsetting interest rate obligation, the portfolio will receive a
      payment from or make a payment to the counterparty. In connection with
      these agreements, cash or securities may be set aside as collateral in
      accordance with the terms of the swap agreement. The Portfolio earns
      interest on cash set aside as collateral. Swaps are marked to market daily
      based upon quotations, which may be furnished by a pricing service or
      dealers in such securities, and the change in value, if any, is recorded
      as unrealized appreciation or depreciation in the Statement of Operations.
      These financial instruments are not actively traded on financial markets.
      The values assigned to these instruments are based upon the best available
      information and because of the uncertainty of the valuation, these values
      may differ significantly from the values that would have been realized had
      a ready market for these instruments existed, and differences could be
      material. Payments received or made at the beginning of the measurement
      period are reflected as such on the Statement of Assets and Liabilities.
      Payments received or made from credit default swaps at the end of the
      measurement period are recorded as realized gain or loss in the Statement
      of Operations. Net payments of interest on interest rate swap agreements,
      if any, are included as part of realized gain and loss. Entering into
      these agreements involves, to varying degrees, elements of credit, market,
      and documentation risk in excess of the amounts recognized in the
      Statement of Assets and Liabilities. Such risks involve the possibility
      that there will be no liquid market for these agreements, that the
      counterparty to the agreements may default on its obligation to perform or
      disagree as to the meaning of contractual terms in the agreements, and
      that there may be unfavorable changes in interest rates.

      At December 31, 2006, the Portfolio held open swap agreements. See the
      Schedule of Investments for further details.

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

(6)   Security Lending:

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

      The Portfolio loaned securities during the year ended December 31, 2006
      and earned interest on the invested collateral of $458,351 of which,
      $450,334 was rebated to borrowers or paid in fees. At December 31, 2006,
      the Portfolio had securities valued at $396,713 on loan. See the Schedule
      of Investments for further detail on the security positions on loan and
      collateral held.

(7)   Delayed Delivery Transactions:

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

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

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

      At December 31, 2006, the Portfolio held delayed delivery securities. See
      the Schedule of Investments for further details.

(8)   Line of Credit:

      The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
      Trust are parties to a committed line of credit facility, which enables
      each portfolio/fund to borrow, in the aggregate, up to $35 million.
      Interest is charged to each participating portfolio/fund based on its
      borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
      1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1%
      on the committed amount, is allocated ratably among the participating
      portfolios/funds at the end of each quarter. The Fund/Portfolio also pays
      an annual renewal fee, computed at a rate of 0.020 of 1% of the committed
      amount and allocated ratably to the participating funds/portfolios. For
      the year ended December 31, 2006, the expense allocated to the Portfolio
      was $613. The facility fee and interest expense are included in
      miscellaneous expenses on the statement of operations.

      For the year ended December 31, 2006, the Portfolio had average borrowings
      outstanding of $1,577,250 for a total of four days and incurred $1,030 of
      interest expense. At December 31, 2006 the Fund had no borrowings
      outstanding.

                   Mellon Institutional Funds Master Portfolio
                 Standish Mellon Global Fixed Income Portfolio

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

To the Trustees of the Mellon Institutional Funds Master Portfolio and Investors
of Standish Mellon Global Fixed Income Portfolio:

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 present fairly, in all
material respects, the financial position of Standish Mellon Global Fixed Income
Portfolio (the "Portfolio") at December 31, 2006, 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 Portfolio'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, 2006 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

                   Mellon Institutional Funds Master Portfolio
                 Standish Mellon Global Fixed Income Portfolio

     Factors Considered by Mellon Trustees in Approving 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. The
      Fund is not a party to an investment advisory agreement directly with any
      investment adviser and does not invest directly in portfolio securities.
      Instead, the Fund invests all of its investable assets in the Standish
      Mellon Global Fixed Income Portfolio (the "Portfolio"), which is managed
      by Standish Mellon Asset Management Company LLC ("Standish Mellon"). The
      Fund's Board of Trustees determines annually whether the Fund should
      continue to invest in the Portfolio. The members of the Fund's Board of
      Trustees also serve as the Board of Trustees of the Portfolio. In that
      capacity, they consider annually whether to continue the investment
      advisory agreement between the Portfolio and 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 the Portfolio's investment adviser,
      Standish Mellon (the "Adviser") a broad range of information in response
      to a written request prepared on their behalf by their own legal counsel.
      The Independent Trustees met alone in a private session with their legal
      counsel on September 28, 2006 to review these materials and to discuss the
      proposed continuation of the Fund's advisory agreement. Representatives of
      the Adviser attended a portion of the September meeting to provide an
      overview of its organization, personnel, resources and strategic plans,
      and to respond to questions and comments arising from the Independent
      Trustees' review of the materials and their deliberations. The entire
      Board then met on October 17, 2006.

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

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

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

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

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

      (v) Other Benefits: The benefits flowing to Mellon Financial Corporation
      ("Mellon") and its affiliates in the form of fees for transfer agency,
      custody, administration and securities lending services provided to the
      Funds by affiliates of 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 Master Portfolio
                 Standish Mellon Global Fixed Income Portfolio

     Factors Considered by Mellon Trustees in Approving 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 28, 2006 Board meeting, the Trustees received similar detailed
      comparative performance information for the Fund at each regular Board
      meeting during the year.

      The Board considered the Fund's performance for the one-, three- and
      five-year periods ended July 31, 2006 based on the Lipper materials
      provided to the Board at the September 28, 2006 meeting. The Board found
      that the Fund outperformed its peer group average returns for the one-year
      period (2.43% vs. 2.08%), but underperformed its peer group average
      returns for the three-year period (4.24% vs. 5.36%) and five-year period
      (4.87% vs. 7.06%).

      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%, 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 0.455% (which included 0.175% in administrative services
      fees under Lipper's calculation methodology), below the peer group median
      net advisory fee of 0.497%. Based on the Lipper data, as well as other
      factors discussed at the September 28, 2006 meeting, the Board determined
      that the Portfolio's advisory fee is reasonable relative with and without
      giving effect to expense limitations.

      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 0.651% (after giving
      effect to expense limitations) was lower than the median net expense ratio
      of the peer group of 0.932% notwithstanding the fact that most of the
      other funds in the peer group were larger than the Fund.

      The Adviser's Profitability

      The Board considered the Adviser's profitability in managing the Portfolio
      and Fund and the Mellon Institutional Funds as a group, as well as the
      methodology used to compute such profitability, and the various direct and
      indirect expenses incurred by the Adviser or its affiliated investment
      adviser, The Boston Company Asset Management, LLC ("TBCAM") 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, including the Portfolio and Fund. The
      Trustees observed that the Adviser had incurred losses in operating the
      Portfolio and Fund in both 2004 and 2005.

      Economies of Scale

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

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

      Other Benefits

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

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

                                      * * *

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

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2006.

Financial markets showed substantial resilience in 2006, shrugging off concerns
that the slowdown in the housing market could drag the rest of the economy into
recession. The U.S. Federal Reserve (Fed) paused in its tightening cycle in
August, after 17 rate hikes since June 2004, as the Fed became convinced that
inflationary forces, and expectations, were under control. Perhaps the most
notable feature of this cycle is that the housing bubble is bursting at a time
when rates are not high. In previous cycles, housing market declines typically
follow a period of Fed tightenings that drive rates to extreme levels, choking
off credit, including mortgage financing. In this environment, credit for
housing and other sectors remains plentiful, with the housing pullback largely a
function of prices soaring beyond affordable levels for many prospective buyers.

The stock market climbed the proverbial "wall of worry" during 2006, with the
S&P 500 hitting new highs and providing a gain of 15.8%, including an 8.8%
advance in the fourth quarter. With U.S. monetary policy moderating, energy
prices in a swoon and the inflation threat receding, investors clearly feel that
the case for a soft landing is being reinforced.

In the bond markets, short-term rates advanced steadily, for the most part, in
cadence with the Fed's rate increases, with the 6-month Treasury bill ending the
year at 4.9%, up about 70 basis points. Rates on longerterm bonds increased to a
lesser degree, with the 10-year Treasury note ending about 30 basis points
higher at 4.7%. This produced an inverted yield curve, which is often a leading
indicator of recession.

Going forward, there is still much debate over the impact of the housing
downturn on the overall economy. We believe that the housing market is in for
prolonged weakness, because rates are already at relatively modest levels. Thus,
the boost provided by lower mortgage rates in the future is likely to be smaller
for housing than in it has been in previous cycles. However, there are other
bullish factors that should mitigate the drag of the housing market. As noted,
liquidity remains plentiful, and corporations are flush with cash. Spreads of
high yield bonds above Treasuries remain tight - an indicator that credit is
still available for riskier borrowers. High yield spreads tend to widen when the
market perceives a recession is likely.

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,

/s/ Patrick J. Sheppard

                       MANAGEMENT DISCUSSION AND ANALYSIS

MARKET ENVIRONMENT

For 2006, the Standish Mellon High Yield Bond Fund (Fund) returned 8.22% as
compared to the 10.76% return of its benchmark, the Merrill Lynch High Yield
Master II Constrained Index. Equity markets were up solidly for the year both in
the U.S. and around the world. Liquidity was extremely strong and riskier assets
prevailed in 2006.

In 2006, the top performing industries included two of last year's laggards. The
automotive industry was up 39.80% in the Constrained benchmark index for the
year. The "fallen angel" automakers, which underperformed in 2005, rallied as
the companies secured financing, enhancing liquidity. Although market shares and
fundamentals stayed weak, the lower probability of near-term defaults led to
strong price performance in industry bonds. The fixed-line telecommunications
industry was a top performer in the benchmark, up 25.19% for the year, as Qwest
and other companies got their financial houses in order. Airlines had the third
best return on an industry basis at 22.85%, as the industry recovered with
rationalized capacity and additional pricing power. The airline industry had the
second lowest return of the benchmark index in 2005. Liquidity was strong and
performance was positive for the benchmark across all industries, except for
beverage, which was down 1.04%. Non-electric utilities and health services were
the second and third laggard industries, but still posted returns of 4.49% and
4.79%, respectively.

From a quality perspective, lower rated/higher risk securities had the best
performance over the year period. The distressed segment of the high yield
market (defined as issuers trading at greater than 10% over Treasury rates), was
the clear outperformer for the year, generating a 42.80% rate of return. CCC's
had a total return of 16.97% in the benchmark Constrained Index, B's returned
10.86% and BB's, the highest rated portion of the high yield market, returned
7.82%. Liquidity was strong in 2006, with an abundant supply of capital chasing
return. A combination of this liquidity and relatively strong balance sheets
kept defaults at an all-time low, as defaults in the U.S. debt markets ended the
year below 2%. However, the availability of capital led to continued increases
in leveraged buyouts, which typically hurt bondholders' returns.

PORTFOLIO STRATEGY REVIEW AND RESULTS

Performance of the Fund in 2006 was hurt by its underweight position relative to
its benchmark index in the automotive industry, cable industry, and the higher
quality bias of the benchmark's holdings. Our industry positioning of the Fund
was defensive in the face of an environment where risk taking was better
rewarded. As default risks were lessened due to strong liquidity, distressed and
lower-rated securities had strong performance. We misjudged the timing of the
turn of the credit cycle in high yield bonds.

                       MANAGEMENT DISCUSSION AND ANALYSIS

INVESTMENT OUTLOOK

We enter 2007 with spreads at historical tight levels. In our view, new issuance
credit quality has been weak. With more private leveraged buyout deals in the
pipeline, we believe issuance patterns will likely continue to be skewed to the
negative. In our view, at some point in the cycle, less liquidity in the market,
an event typically driven by weaker fundamentals and then higher defaults, will
drive spreads wider. The key is timing. We believe we have seen the peak in
credit improvement in 2006, but current liquidity and the thirst for yield could
keep demand strong for high yield bonds. Our strategy for 2007 includes the need
to focus on security selection opportunities to allow incremental yield in the
portfolio, while continuing to maintain a higher quality bias.

Average annual total returns reflect the change in the value of an investment,
assuming reinvestment of the fund' 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 funds total return will be 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, 2006 to December 31, 2006).

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000=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 HIGH YIELD BOND 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 High Yield Bond Fund (the "Fund") is a separate diversified
     investment series of the Trust.

     The object of the Fund is to maximize total return, consisting of a high
     level of income. The Fund invests all of its investable assets in an
     interest in Standish Mellon High Yield Bond Portfolio (the "Portfolio"), a
     subtrust of Mellon Institutional Funds Master Portfolio (the "Portfolio
     Trust"), which is organized as a New York trust and has the same investment
     objective as the Fund. The Portfolio seeks to achieve its objective by
     investing, under normal circumstances, at least 80% of net assets in below
     investment grade fixed income securities issued by U.S. and foreign
     governments, companies and banks, as well as tax-exempt securities,
     preferred stocks and warrants. The value of the Fund's investment in the
     Portfolio reflects the Fund's proportionate interest in the net assets of
     the Portfolio (100% at December 31, 2006). The performance of the Fund is
     directly affected by the performance of the Portfolio. The financial
     statements of the Portfolio are included elsewhere in this report and
     should be read in conjunction with the Fund's financial statements.

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

     A.   INVESTMENT SECURITY VALUATIONS

     Fund shares are valued as of the close of regular trading (normally 4:00
     p.m., Eastern Time) on each day that the New York Stock Exchange ("NYSE")
     is open. The Fund records its investment in the Portfolio at value. The
     Portfolio values its securities at value as discussed in Note 1A of the
     Portfolio's Notes to Financial Statements, which are included elsewhere in
     this report.

     B.   SECURITIES TRANSACTIONS AND INCOME

     The Fund's investment in the Portfolio is recorded on settlement date. The
     Portfolio's securities transactions are recorded as of the trade date as
     discussed in Note 1B of the Portfolio's Notes to Financial Statements,
     which are included elsewhere in this report. Currently, the Fund's net
     investment income consists of the Fund's pro rata share of the net
     investment income of the Portfolio, less all expenses of the Fund
     determined in accordance with accounting principles generally accepted in
     the United States of America. All realized and unrealized gains and losses
     of the Fund represent pro rata shares of gains and losses of the Portfolio.

     C.   DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date. The
     Fund's distributions from capital gains, if any, after reduction of capital
     losses are declared and distributed at least annually. In determining the
     amounts of its dividends, the Fund will take into account its share of the
     income, gains or losses, expenses, and any other tax items of the
     Portfolio. Dividends from net investment income and distributions from
     capital gains, if any, are reinvested in additional shares of the Fund
     unless a shareholder elects to receive them in cash.

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

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications among undistributed net
     investment income(loss), accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income (loss) and accumulated net
     realized gain (loss) on investments may include temporary book and tax
     basis differences which will reverse in a subsequent period. Any taxable
     income or gain remaining at fiscal year end is distributed in the following
     year.

     D.   EXPENSES

     The majority of expenses of the Trust or Portfolio Trust are directly
     identifiable to an individual fund or portfolio. Expenses which are not
     readily identifiable to a specific fund or portfolio are allocated among
     funds of the Trust and/or portfolios of the Portfolio Trust taking into
     consideration, among other things, the nature and type of expense and the
     relative size of the funds or portfolios.

                          NOTES TO FINANCIAL STATEMENTS

     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.   FEDERAL INCOME 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.

     G.   NEW ACCOUNTING REQUIREMENTS

     In July 2006, the Financial Accounting Standards Board issued
     Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
     Interpretation of FASB Statement No. 109" (the "Interpretation"). The
     Interpretation establishes for all entities, including pass-through
     entities such as the Portfolio, a minimum threshold for financial statement
     recognition of the benefit of positions taken in filing tax returns
     (including whether an entity is taxable in a particular jurisdiction), and
     requires certain expanded tax disclosures. Adoption of FIN 48 is required
     for fiscal years beginning after December 15, 2006 and is to be applied to
     all open tax years as of the effective date. At this time, management is
     evaluating the implications of FIN 48 and its impact, if any, in the
     financial statements has not yet been determined.

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

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary of Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report. Standish Mellon voluntarily agreed to
     limit the total operating expenses of the Fund and its pro rata share of
     the Portfolio expenses (excluding brokerage commissions, taxes and
     extraordinary expenses) to 0.50% of the Fund's average daily net assets.
     Pursuant to this agreement, for the year ended December 31, 2006, Standish
     Mellon voluntarily reimbursed the Fund for $74,358 of its operating
     expenses. This agreement is voluntary and temporary and may be discontinued
     or revised by Standish Mellon at any time.

     On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
     New York Company, Inc. ("BNY") announced that they had entered into a
     definitive agreement to merge. The new company will be called The Bank of
     New York Mellon Corporation. As part of this transaction, Standish Mellon
     would become an indirect wholly-owned subsidiary of The Bank of New York
     Mellon Corporation. The transaction is subject to certain regulatory
     approvals and the approval of BNY's and MFC's shareholders, as well as
     other customary conditions to closing. Subject to such approvals and the
     satisfaction of the other conditions, MFC and BNY expect the transaction to
     be completed in the third quarter of 2007.

     The Trust entered into an agreement with Dreyfus Transfer, Inc., a wholly
     owned subsidiary of The Dreyfus Corporation, a wholly owned subsidiary of
     Mellon Financial Corporation and an affiliate of Standish Mellon, to
     provide personnel and facilities to perform transfer agency and certain
     shareholder services for the Fund. For these services, the Fund pays
     Dreyfus Transfer, Inc. a fixed fee plus per account and transaction based
     fees, well as, out-of-pocket expenses. Pursuant to this agreement the Fund
     was charged $6,671, for the year ended December 31, 2006.

     The Trust has contracted Mellon Investor Services LLC, a wholly owned
     subsidiary of Mellon Financial Corporation and an affiliate of Standish
     Mellon, to provide printing and fulfillment services for the Fund. Pursuant
     to this agreement, the Fund was charged $3,300 for the year ended December
     31, 2006.

     The Trust reimburses Mellon Asset Management for a portion of the salary of
     the Trust's Chief Compliance Officer. For the year ended December 31, 2006,
     the Fund was charged $4,041. No other director, officer or employee of
     Standish Mellon or its affiliates receives any compensation from the Trust
     or the Portfolio Trust for serving as an officer or Trustee of the Trust.
     The Fund pays each Trustee who is not a officer or employee of Standish
     Mellon or its affiliates an annual fee.

                          NOTES TO FINANCIAL STATEMENTS

      The Fund pays administrative service fees. These fees are paid to
      affiliated or unaffiliated retirement plans, omnibus accounts and platform
      administrators and other entities ("Plan Administrators") that provide
      record keeping and/or other administrative support services to accounts,
      retirement plans and their participants. As compensation for such
      services, the Fund may pay each Plan Administrator an administrative
      service fee in an amount of up to 0.15% (on an annualized basis) of the
      Fund's average daily net assets attributable to Fund shares that are held
      in accounts serviced by such Plan Administrator. The Fund's adviser or its
      affiliates may pay additional compensation from their own resources to
      Plan Administrators and other entities for administrative services, as
      well as in consideration of marketing or other distribution-related
      services. These payments may provide an incentive for these entities to
      actively promote the Fund or cooperate with the distributor's promotional
      efforts. For the year ended December 31, 2006, the Fund was charged $1,344
      for fees payable to Mellon Private Wealth Management.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended December 31, 2006, aggregated $17,582,918 and $9,647,661,
     respectively. The Fund receives a proportionate share of the Portfolio's
     income, expenses, and realized and unrealized gains and losses based on
     applicable tax allocation rules.

(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, 2006, three shareholders of record held in the aggregate
     approximately 83% 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 year ended December 31, 2006, the Fund received $593
     in redemption fees.

(5)  FEDERAL TAXES:

     As of December 31, 2006, the components of distributable earnings on a tax
     basis were as follows:

     Tax character of distributions paid during the fiscal year ended December

                          NOTES TO FINANCIAL STATEMENTS

At December 31, 2006, 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:

===========


During 2006, the Fund utilized $60,270 in capital loss carry forwards.
Utilization of the capital loss carryovers above could be subject to limitations
imposed by the Internal Revenue Code related to share ownership activity.

The Fund elected to defer to its fiscal year ending December 31, 2007, $9,987 of
capital losses and $24,788 of currency losses recognized during the period
November 1, 2006 to December 31, 2006.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees of the Mellon Institutional Funds Investment Trust and
Shareholders of Standish Mellon High Yield Bond Fund:

In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Standish Mellon High Yield Bond Fund (the "Fund") at December 31, 2006, 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 agreement of the amount of the investment in the Standish
Mellon High Yield Bond Portfolio (the "Portfolio") at December 31, 2006 to the
Portfolio's records, provide a reasonable basis for our opinion.

                  MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
                   STANDISH MELLON HIGH YIELD BOND PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS

(1)  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES:

     Mellon Institutional Funds Master Portfolio (the "Portfolio Trust") was
     organized as a master trust fund under the laws of the State of New York on
     January 18, 1996 and is registered under the Investment Company Act of
     1940, as amended, as an open-end, management investment company. Standish
     Mellon High Yield Bond Portfolio (the "Portfolio") is a separate
     diversified investment series of the Portfolio Trust.

     The objective of the Portfolio is to maximize total return, consisting
     primarily of a high level of income. The Portfolio seeks to achieve its
     objective by investing, under normal circumstances, at least 80% of net
     assets in below investment grade fixed income securities issued by U.S. and
     foreign governments, companies and banks, as well as tax-exempt securities,
     preferred stocks and warrants.

     At December 31, 2006 there was one fund, Standish Mellon High Yield Bond
     Fund (the "Fund"), invested in the Portfolio. The value of the Fund's
     investment in the Portfolio reflects the Fund's proportionate interest in
     the net assets of the Portfolio. The Fund's proportionate interest at
     December 31, 2006 was 100%.

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

     A.   INVESTMENT SECURITY VALUATIONS

     Securities are valued at the last sale prices on the exchange or national
     securities market on which they are primarily traded. Securities not listed
     on an exchange or national securities market, or securities for which there
     were no reported transactions, are valued at the last quoted bid price.
     Securities that are fixed income securities, other than short-term
     instruments with less than sixty days remaining to maturity, for which
     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.

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

     Short-term instruments with less than sixty days remaining to maturity are
     valued at amortized cost, which approximates market value. If the Portfolio
     acquires a short-term instrument with more than sixty days remaining to its
     maturity, it is valued at current market value until the sixtieth day prior
     to maturity and then is valued at amortized cost based upon the value on
     such date unless the Trustees determine during such sixty-day period that
     amortized cost does not represent fair value.

     B.   SECURITIES TRANSACTIONS AND INCOME

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

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

     C.   INCOME TAXES

     The Portfolio is treated as a disregarded entity for federal tax purposes.
     No provision is made by the Portfolio for federal or state income taxes on
     any taxable income of the Portfolio because each investor in the Portfolio
     is ultimately responsible for the payment of any taxes. Since the
     Portfolio's investor is a regulated investment company that invests all or
     substantially all of its assets in the Portfolio, the Portfolio normally
     must satisfy the source of income and diversification requirements
     applicable to regulated investment companies (under the Internal Revenue
     Code) in order for its investors to satisfy them.

                                       29


                  MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
                   STANDISH MELLON HIGH YIELD BOND PORTFOLIO

                         NOTES TO FINANCIAL STATEMENTS

     Section 988 of the Internal Revenue Code provides that gains or losses on
     certain transactions attributable to fluctuations in foreign currency
     exchange rates must be treated as ordinary income or loss. For financial
     statement purposes, such amounts are included in net realized gains or
     losses.

     D.   FOREIGN CURRENCY TRANSACTIONS

     The Portfolio maintains its books and records in U.S. dollars. Investment
     security valuations, other assets, and liabilities initially expressed in
     foreign currencies are converted into U.S. dollars based upon current
     currency exchange rates. Purchases and sales of foreign investment
     securities and income and expenses are converted into U.S. dollars based
     upon currency exchange rates prevailing on the respective dates of such
     transactions.

     E.   FOREIGN INVESTMENT RISK

     There are certain additional risks involved in investing in foreign
     securities that are not inherent in investments in domestic securities.
     These risks may involve adverse political and economic developments,
     including the possible imposition of capital controls or other foreign
     governmental laws or restrictions. In addition, the securities of some
     foreign companies and securities markets are less liquid and at times may
     be more volatile than securities of comparable U.S. companies and U.S.
     securities markets. The risks described above apply to an even greater
     extent to investments in emerging markets. The securities markets of
     emerging countries are generally smaller, less developed, less liquid, and
     more volatile than the securities markets of the U.S. and developed foreign
     markets.

     F.   COMMITMENTS AND CONTINGENCIES

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

     G.   EXPENSES

     The majority of expenses of the Trust or Portfolio Trust are directly
     identifiable to an individual fund or portfolio. Expenses which are not
     readily identifiable to a specific fund or portfolio are allocated among
     the funds of the Trust or the portfolios of the Portfolio Trust taking into
     consideration, among other things, the nature and type of expense and the
     relative size of the funds or portfolios.

     H.   AFFILIATED ISSUERS

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

     I.   NEW ACCOUNTING REQUIREMENTS

     In July 2006, the Financial Accounting Standards Board issued
     Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
     Interpretation of FASB Statement No. 109" (the "Interpretation"). The
     Interpretation establishes for all entities, including pass-through
     entities such as the Portfolio, a minimum threshold for financial statement
     recognition of the benefit of positions taken in filing tax returns
     (including whether an entity is taxable in a particular jurisdiction), and
     requires certain expanded tax disclosures. Adoption of FIN 48 is required
     for fiscal years beginning after December 15, 2006 and is to be applied to
     all open tax years as of the effective date. At this time, management is
     evaluating the implications of FIN 48 and its impact, if any, in the
     financial statements has not yet been determined.

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

(2)  INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services, and general office facilities is paid
     monthly at the annual rate of 0.50% of the Portfolio's average daily net
     assets. Standish Mellon voluntarily agreed to limit the Portfolio's total
     annual operating expenses (excluding brokerage commissions, taxes and
     extraordinary expenses) to 0.50% of the Portfolio's average daily net
     assets for the year ended December 31, 2006. Pursuant to this agreement,
     for the year ended December 31, 2006, Standish Mellon voluntarily waived
     all of its investment advisory fee in the amount of $87,385 and reimbursed
     the Portfolio for operating expense in the amount of $26,657. This
     agreement is voluntary and temporary and may be discontinued or revised by
     Standish Mellon at any time.

     On December 4, 2006, Mellon Financial Corporation ("MFC") and The Bank of
     New York Company, Inc. ("BNY") announced that they had entered into a
     definitive agreement to merge. The new company will be called The Bank of
     New York Mellon Corporation. As part of this transaction, Standish Mellon
     would become an indirect wholly-owned subsidiary of The Bank of New York
     Mellon Corporation. The transaction is subject to certain regulatory
     approvals and the approval of BNY's and MFC's shareholders, as well as
     other customary conditions to closing. Subject to such approvals and the
     satisfaction of the other conditions, MFC and BNY expect the transaction to
     be completed in the third quarter of 2007.

     The Portfolio Trust has entered into an agreement with Mellon Bank, N.A.
     ("Mellon Bank"), a wholly owned subsidiary of Mellon Financial Corporation
     and an affiliate of Standish Mellon, to provide custody, administration and
     fund accounting services for the Portfolio. For these services the
     Portfolio pays Mellon Bank a fixed fee plus asset and transaction based
     fees, as well as out-of-pocket expenses. Pursuant to this agreement the
     Portfolio was charged $67,376 during the year ended December 31, 2006.

     The Portfolio Trust also entered into an agreement with Mellon Bank to
     perform certain securities lending activities and to act as the Portfolio's
     lending agent. Mellon Bank receives an agreed upon percentage of the net
     lending revenues. Pursuant to this agreement, Mellon Bank earned $964 for
     the year ended December 31, 2006. See Note 6 for further details.

     The Trust reimburses Mellon Asset Management for a portion of the salary of
     the Trust's and Portfolio Trust's Chief Compliance Officer. No other
     director, officer or employee of Standish Mellon or its affiliates received
     any compensation from the Trust or the Portfolio Trust for serving as an
     officer or Trustee of the Trust or the Portfolio Trust. The Fund and
     Portfolio Trust pays each Trustee who is not a director, officer or
     employee of Standish Mellon or its affiliates (the "Independent Trustees")
     an annual fee and the Portfolio Trust pays each Independent Trustee a per
     meeting fee as well as reimbursement for travel and out of pocket expenses.
     In addition, the Portfolio Trust pays the legal fees for the counsel to the
     Independent Trustees.

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, other than short-term
     obligations, for the year ended December 31, 2006 were as follows:



                                        PURCHASES               SALES

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


(4)  FEDERAL TAXES:

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at December 31, 2006, as computed on a federal
     income tax basis, were as follows:

(5)  FINANCIAL INSTRUMENTS:

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

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

                                       31


                  MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
                   STANDISH MELLON HIGH YIELD BOND PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS

     FORWARD CURRENCY EXCHANGE CONTRACTS

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

     At December 31, 2006, the Portfolio held forward currency exchange
     contracts. See the Schedule of Investments for further details.

     SWAP AGREEMENTS

     The Portfolio may enter into swap agreements. A swap is an agreement to
     exchange the return generated by one instrument for the return generated by
     another instrument. The Portfolio may enter into interest rate, credit
     default and total return swap agreements to manage its exposure to interest
     rates and credit risk. Interest rate swap agreements involve the exchange
     by the Portfolio with another party of their respective commitments to pay
     or receive interest, e.g., an exchange of floating rate payments for fixed
     rate payments with respect to a notional amount of principal. In a credit
     default swap, one party makes a stream of payments to another party in
     exchange for the right to receive a specified return in the event of a
     default by a third party on its obligation. The Portfolio may use credit
     default swaps to provide a measure of protection against defaults of
     issuers (i.e., to reduce risk where the Portfolio owns or has exposure to
     the corporate or sovereign issuer) or to take an active long or short
     position with respect to the likelihood of a particular corporate or
     sovereign issuer's default. Total return swap agreements involve
     commitments to pay interest in exchange for a market-linked return, both
     based on notional amounts. To the extent the total return of the security
     or index underlying the transaction exceeds or falls short of the
     offsetting interest rate obligation, the portfolio will receive a payment
     from or make a payment to the counterparty. In connection with these
     agreements, cash or securities may be set aside as collateral in accordance
     with the terms of the swap agreement. The Portfolio earns interest on cash
     set aside as collateral. Swaps are marked to market daily based upon
     quotations, which may be furnished by a pricing service or dealers in such
     securities and the change in value, if any, is recorded as unrealized
     appreciation or depreciation in the Statement of Operations. These
     financial instruments are not actively traded on financial markets. The
     values assigned to these instruments are based upon the best available
     information and because of the uncertainty of the valuation, these values
     may differ significantly from the values that would have been realized had
     a ready market for these instruments existed, and differences could be
     material. Payments received or made at the beginning of the measurement
     period are reflected as such on the Statement of Assets and Liabilities.
     Payments received or made from credit default swaps at the end of the
     measurement period are recorded as realized gain or loss in the Statement
     of Operations. Net payments of interest on interest rate swap agreements,
     if any, are included as part of realized gain and loss. Entering into these
     agreements involves, to varying degrees, elements of credit, market, and
     documentation risk in excess of the amounts recognized in the Statement of
     Assets and Liabilities. Such risks involve the possibility that there will
     be no liquid market for these agreements, that the counterparty to the
     agreements may default on its obligation to perform or disagree as to the
     meaning of contractual terms in the agreements, and that there may be
     unfavorable changes in interest rates.

     At December 31, 2006, the Portfolio held open swap agreements. See the
     Schedule of Investments for further details.

(6)  SECURITY LENDING:

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

     The Portfolio loaned securities during the year ended December 31, 2006 and
     earned interest on the invested collateral of $64,717 of which, $62,458 was
     rebated to borrowers or paid in fees. At December 31, 2006, the Portfolio

(7)  LINE OF CREDIT:

     The Portfolio, and other subtrusts in the Portfolio Trust and funds in the
     Trust are parties to a committed line of credit facility, which enables
     each portfolio/fund to borrow, in the aggregate, up to $35 million.
     Interest is charged to each participating portfolio/fund based on its
     borrowings at a rate equal to the Federal Funds effective rate plus 1/2 of
     1%. In addition, a facility fee, computed at an annual rate of 0.060 of 1%
     on the committed amount, is allocated ratably among the participating
     portfolios/funds at the end of each quarter. The Fund/Portfolio also pays
     an annual renewal fee, computed at a rate of 0.020 of 1% of the committed
     amount and allocated ratably to the participating funds/portfolios. For the
     year ended December 31, 2006, the expense allocated to the Portfolio was
     $1,011. The facility fee and interest expense are included in miscellaneous
     expenses on the statement of operations.

     For the year ended December 31, 2006, the Portfolio had average borrowings
     outstanding of $375,182 for a total of twenty-two days and incurred $1,389
     of interest expense. At December 31, 2006 the Fund had a $714,000 loan
     balance outstanding.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees of the Mellon Institutional Funds Master Portfolio and Investors
of Standish Mellon High Yield Bond Portfolio:

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 present fairly, in all
material respects, the financial position of Standish Mellon High Yield Bond
Portfolio (the "Portfolio") at December 31, 2006, 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 our audits of these financial these financial statements based on
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, 2006 by correspondence with the custodian and brokers, provide a
reasonable basis for our opinion.

                  MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
                   STANDISH MELLON HIGH YIELD BOND PORTFOLIO

     FACTORS CONSIDERED BY MELLON TRUSTEES IN APPROVING ADVISORY AGREEMENT
                                  (UNAUDITED)

The 1940 Act requires that the Board of Trustees, including a majority of its
Trustees who are not affiliated with the fund's investment adviser or
underwriter (the "Independent Trustees") voting separately, approve the fund's
advisory agreement and the related fees on an annual basis. The Fund is not a
party to an investment advisory agreement directly with any investment adviser
and does not invest directly in portfolio securities. Instead, the Fund invests
all of its investable assets in the Standish Mellon High Yield Bond Portfolio
(the "Portfolio"), which is managed by Standish Mellon Asset Management Company
LLC ("Standish Mellon"). The Fund's Board of Trustees determines annually
whether the Fund should continue to invest in the Portfolio. The members of the
Fund's Board of Trustees also serve as the Board of Trustees of the Portfolio.
In that capacity, they consider annually whether to continue the investment
advisory agreement between the Portfolio and 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 the
Portfolio's investment adviser, Standish Mellon (the "Adviser") a broad range of
information in response to a written request prepared on their behalf by their
own legal counsel. The Independent Trustees met alone in a private session with
their legal counsel on September 28, 2006 to review these materials and to
discuss the proposed continuation of the Fund's advisory agreement.
Representatives of the Adviser attended a portion of the September meeting to
provide an overview of its organization, personnel, resources and strategic
plans, and to respond to questions and comments arising from the Independent
Trustees' review of the materials and their deliberations. The entire Board then
met on October 17, 2006.

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

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

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

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

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

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

     FACTORS CONSIDERED BY BOARD OF TRUSTEES IN APPROVING ADVISORY AGREEMENT
                                   (UNAUDITED)

INVESTMENT PERFORMANCE

The Board considered the investment performance of the Fund (rather than the
Portfolio alone) against a peer group of investment companies selected by the
Adviser with input from the Trustees. The Board also compared the Fund's
investment performance against the average performance of a larger universe of
funds regarded by Lipper as having similar investment objectives and considered
the Fund's performance rankings against that universe. In addition to the
information received by the Board at the September 28, 2006 Board meeting, the
Trustees received similar detailed comparative performance information for the
Fund at each regular Board meeting during the year.

The Board considered the Fund's performance for the one-, three- and five-year
periods ended July 31, 2006 based on the Lipper materials provided to the Board
at the September 28, 2006 meeting. The Board found that the Fund underperformed
its peer group average returns for the one-year period (3.03% vs. 4.29%),
three-year period (7.95% vs. 9.35%) and five-year period (8.14% vs. 8.59%). The
Board noted that Standish Mellon had discussed possible changes within the
Fund's portfolio management team and further noted the Fund's improved recent
performance, which was reported in the October 17, 2006 meeting's materials.

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 0.50%, in the 2nd quintile (1st
being the best) of its peer group of funds, the median fee of which was 0.60%.
The Portfolio's entire management fee (including certain administrative services
fees allocated under Lipper's calculation methodology) was reimbursed pursuant
to an expense limitation agreement. By comparison, the peer group median net
management fee was 0.552%. Based on the Lipper data, as well as other factors
discussed at the September 28, 2006 meeting, the Board determined that the
Portfolio's advisory fee is reasonable relative to its peer group averages, both
with and without giving effect to expense limitations.

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 0.50% (after giving effect to
expense limitations) was lower than the median net expense ratio of the peer
group of 0.757% notwithstanding the fact that most of the other funds in the
peer group were larger than the Fund.

THE ADVISER'S PROFITABILITY

The Board considered the Adviser's profitability in managing the Portfolio and
Fund and the Mellon Institutional Funds as a group, as well as the methodology
used to compute such profitability, and the various direct and indirect expenses
incurred by the Adviser or its affiliated investment adviser, The Boston Company
Asset Management, LLC ("TBCAM") 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, including the
Portfolio and Fund. The Trustees observed that the Adviser had incurred losses
in operating the Portfolio and Fund in both 2004 and 2005.

ECONOMIES OF SCALE

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

                                  (UNAUDITED)

OTHER BENEFITS

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

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

                                     * * *

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