Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.

The year was largely positive for the financial markets, as the economic
expansion continued. However,  as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point  in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

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

MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST STANDISH MELLON HIGH YIELD BOND FUN

                      MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

For the year 2004 the Standish Mellon High Yield Bond Fund has returned 9.56%
while the Merrill Lynch Master II High Yield Index was up 10.87%. The 10-year US
Treasury yield closed the month at 4.22%, down from 4.35% at the November close
and basically coming full circle from its starting point (4.25%) at the start of
the year. The Lehman Aggregate Index gained .92% in December and finished with a
2004 return of 4.34%. On an index comparison basis high yield has bested higher
quality fixed income by over 600 basis points in 2004. With a strong fourth
quarter, equities had a good year in 2004 as the S&P 500 gained 10.74% and small
cap stocks performed significantly better than that. The other star in the fixed
income asset class was Emerging Markets, which, along with high yield closed the
year with a string of good months and recorded a 2004 return of close to 12%.

During the year the Index benchmark for the Fund was changed from the Lehman
Brothers US High Yield Index to the Merrill Lynch Master II High Yield Index.
Both indexes use similar methodology but the change was made for reasons of
market acceptance, usability and transparency to outside investors. The Lehman
High Yield Index returned 11.13% for 2004.

As the high yield rally has continued in the last four months, lower quality
names have led performance.  For December CCC-rated bonds returned a healthy
+3.09%, and as they did in November, October and September, clearly outdistanced
both the BB (+1.24%) and B (+1.16%) quality sectors. The hot performance of
CCC's in the last four months of 2004 has left the relative performance
situation in high yield an almost miniature repeat of 2003, with lower-priced,
higher-yielding bonds significantly outperforming issues from stronger credits.
For the year BB's reported a YTD result of +9.33%, B's stand at +10.44% and
CCC's finished with a remarkable return of +15.75%.

The lower quality theme favoring higher yields and lower dollar prices during
2004 was even more clearly demonstrated by the performance of the market's
distressed credits. Looking at credit quality on a ratings-blind basis shows
distressed credits (those with spreads greater than 1,000 basis points over
Treasuries) had another huge month in December at +7.44% as compared to
non-distressed names return of 1.24%. Spreads on the non-distressed cohort
widened a small bit in December from +271 to +279. With strong performance in
the fourth quarter, bonds categorized as distressed (+24.78% annual return)
outperformed their non-distressed peers (+10.23%) in 2004.

As was the case in the previous two months, outperformance by speculative,
distressed credits dominated the top industry returns in December, primarily
driven by snapbacks in some of the sectors that have struggled for most of the
year. Air Transport again topped this list as labor negotiation progress and
some relief on the fuel cost front boosted optimism and produced a monthly
return of 7.23%. Airlines remain as the only losing sector on the year at -.40%.
Telecom was another winner in December at +2.28%. No industries had negative
returns for the month. Some of the weaker December performances were turned in
by some of the market's more stable sectors including Consumer Products (.57%),
Gaming (+.75%) and the previously strong Building Materials sector (+.50%).

                                       2

Generally speaking industry returns were quite closely bunched in 2004 with
Airlines being the only  industry without a positive yearly return. The Fund had
a small exposure to the airline sector through some EETC holdings in Continental
and Northwest Airlines, two of the more liquid companies in a tough industry.
Those holdings were actually a small positive for performance as they were
purchased at favorable prices. The snap back dynamic among sectors that
underperformed in 2003 sponsored the year's big industry winners as Textile and
Apparel (+28.08 2004 return), Steel (+19.32%) and Chemicals (+15.48%) topped
the yearly return chart. With the exception of Chemicals none of these
industries represents a large part of the high yield market.

On an issuer specific basis the largest index contributions came from three
sources: 1) recovering pipelines and utilities (El Paso, Williams and Edison
International) 2) Wireline Telecom (AT&T, Quest and MCI) and 3) large distressed
issuers (Charter, Calpine and Levi Strauss). The Fund had large exposures to the
pipeline and utility area which was helpful to performance although our holdings
were concentrated more in the regulated operating pipeline and first mortgage
utility bonds than in the holding company issues that provided the very largest
returns. Although we did have investments (where permitted by ratings
guidelines) to the wireline telecom providers our exposure was smaller than the
index and focused on the safety of operating-company and shorter-maturity bonds.
Our stance here was dictated by continued competition and the technological
threats to the business model of these companies. Lastly, Standish portfolios
are never highly exposed to distressed issuers. We did not like in 2004 and
continue not to like for 2005, the finances of Charter or Calpine. Neither
company looks like it can come close to supporting its current debt load and
both situations appear to contain large risks to the capital of bondholders
despite the two issuers ability to solve liquidity problems by accessing the
high yield market by issuing various types of secured paper.

MARKET ENVIRONMENT

In 2004 high yield investors were once more handsomely rewarded for
concentrating on the highest yielding opportunities in the market. Risk seeking
investors also had a big hand in shaping the composition of the new issues that
came to market as speculative-grade issues represented a large share of new
deals. In 2004 new global high yield issuance hit an all-time record of over
$160 billion. Almost 20% of that new issuance was rated speculative grade CCC or
lower. As a contrast in 2003 about 7% of new issuance carried speculative
ratings and, in the credit stressed environment of 2001 and 2002, the share was
around 3%. An interesting note on the demand side was the fervent search for
high yield bonds that took place despite annual outflows of over $4 billion from
high yield mutual funds. Yield-thirsty institutional investors and other
constituencies such, as hedge funds and structured credit vehicles, more than
made up for the slide in retail demand as compared to 2003 when mutual funds had
significant inflows.
                                       3

PORTFOLIO STRATEGY AND OUTLOOK

On the year high yield spreads tightened over 100 basis points as the broad ML
Master II Index spread fell from 418 bp at the close of 2003 to +310 at year-end
2004. Much of this spread tightening took place in the fourth quarter of the
year. High yield is now at a point where the market looks overpriced on the
basis of historically very low yields (the average B-rated bond yields about
6.80%) and spreads, combined with a risky overall ratings profile given the
expansion of speculative rated securities. The broad Merrill Lynch Index now has
14% of its market value in CCC and lower rated securities and the similar Lehman
index reports over 17%. This extreme valuation situation is more stable than it
appears however as a number of positive market forces derived from stable credit
conditions and an acute lack of attractive yield-oriented investment
alternatives have provided supporting technicals and comfort to investors
holding credit risk.

Over the last half of 2004 the credit risk of the Standish portfolio has been
reduced a bit and even more focus has been placed on identifying improving
credit situations. The portfolio also now holds a number of floating-rate high
yield bond issues and these should continue to provide good performance and
serve as a counterbalance to some of the longer duration investments that have
been made in improving credits where spreads are expected to tighten. As always
credit vigilance will be high and that should be the driver of portfolio returns
in 2005.

                          SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

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, 2004 to December 31, 2004).

ACTUAL EXPENSES

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

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

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

(a)  The Fund has adopted the provisions of the revised AICPA Audit and
Accounting Guide for Investment Companies effective January 1, 2001 and began
amortizing premium and discount on all debt securities on an effective yield
basis. The effect of this change for the year ended December 31, 2001 was to
decrease net investment income per share by $0.05, increase net realized and
unrealized gains and losses per share by $0.05 and decrease the ratio of net
investment income to average net assets from 9.20% to 8.86%. Per share data and
ratios/supplemental data for the periods prior to January 1, 2001 have not been
restated to reflect this change in presentation.

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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 objective of the Fund is to maximize total return, consisting primarily
     of a high level of income. The Fund seeks to achieve its objective by
     investing all of its investable assets in an interest of the Standish
     Mellon High Yield Bond Portfolio (the "Portfolio"), a subtrust of the
     Mellon Institutional Funds Master Portfolio (the "Portfolio Trust"), which
     is organized as a New York trust and which has the same investment
     objective as the Fund. The Portfolio seeks to achieve its objective by
     investing, under normal circumstances, at least 80% of net assets in 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 (approximately
     100% at December 31, 2004). The performance of the Fund is directly
     affected by the performance of the Portfolio. The financial statements of
     the Portfolio are included elsewhere in this report and should be read in
     conjunction with the Fund's financial statements

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

     A. INVESTMENT SECURITY VALUATIONS

     The Fund records its investment in the Portfolio at value. The method by
     which the Portfolio values its securities is discussed in Note 1A of the
     Portfolio's Notes to Financial Statements, which are included elsewhere in
     this report.

     B. INVESTMENT TRANSACTIONS AND INCOME

     Investment transactions in the Portfolio are recorded as of the settlement
     date of shareholder transactions. 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 Portfolio are allocated pro rata
     among the investors in the Portfolio.

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared daily and distributed
     monthly. The Fund's dividends from short-term and long-term capital gains,
     if any, after reduction of capital losses will be declared and distributed
     at least annually. In determining the amounts of its dividends, the Fund
     will take into account its share of the income, gains or losses, expenses,
     and any other tax items of the Portfolio. Dividends from net investment
     income and distributions from capital gains, if any, are reinvested in
     additional shares of the Fund unless a shareholder elects to receive them
     in cash. Income and capital gain distributions are determined in accordance
     with income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in distribution reclassifications, are primarily due to
     differing treatments for capital loss carryforwards and amortization and/or
     accretion of premiums and discounts on certain securities.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications to undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments and foreign currency transactions 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 are allocated taking into
     consideration, among other things, the nature and type of expense and the
     relative size of the funds or Portfolios.

     E. COMMITMENTS AND CONTINGENCIES

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

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary of Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report. Standish Mellon voluntarily agreed to
     limit the total operating expenses of the Fund and its pro rata share of
     the Portfolio expenses (excluding commissions, taxes and extraordinary
     expenses) to 0.50% of the Fund's average daily net assets. This agreement
     is voluntary and temporary and may be discontinued or revised by Standish
     Mellon at any time. Pursuant to this agreement, for the year ended December
     31, 2004, Standish Mellon voluntarily reimbursed the Fund for $63,250 of
     its operating expenses.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services, the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per
     account and transaction based fees, as well as, out-of-pocket expenses.
     Pursuant to this agreement the Fund paid $5,171 during the period ended
     December 31, 2004.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended December 31, 2004, aggregated $10,724,449 and $16,197,718,
     respectively.

(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, 2004, two shareholders of record held approximately 77% of
     the total outstanding shares of the Fund. Investment activity 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
     90 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. The fee does
     not apply to shares that were acquired through reinvestment of
     distributions. For the year ended December 31, 2004, the Fund received $248
     in redemption fees.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

     As of December 31, 2004, the components of distributable earnings on a tax
     basis were as follows:
                                                           2004

                  Accumulated losses                  (10,154,928)

     At December 31, 2004, the Fund, for federal income tax purposes, has
     capital loss carryovers of $10,154,928 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:

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     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, 2004, and the results of its operations, the changes in its
     net assets and the financial highlights for each of the periods indicated,
     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, 2004 to the Portfolio's records, provide a reasonable basis
     for our opinion.

(a)  The Portfolio has adopted the provisions of the revised AICPA Audit and
Accounting Guide for Investment Companies effective January 1, 2001 and began
amortizing premium and discount on all debt securities on an effective yield
basis. The effect of this change for the year ended December 31, 2001 was to
decrease the ratio of the net investment income to average net assets from 9.20%
to 8.87%. Ratios for the periods prior to January 1, 2001 have not been restated

                   STANDISH MELLON HIGH YIELD BOND PORTFOLIO

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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 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, 2004 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, 2004 was approximately 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 for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are normally traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

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

     B. Securities transactions and income

     Securities transactions are recorded as of trade date of shareholder
     transactions. Interest income is determined on the basis of interest
     accrued, adjusted for accretion of discount or amortization of premium
     using the yield - to - maturity method on long-term debt securities and
     short-term securities with greater than sixty days to maturity. Realized
     gains and losses from securities sold are recorded on the identified cost
     basis. The Portfolio does not isolate that portion of the results of
     operations resulting from changes in foreign exchange rates on investments
     from the fluctuations arising from changes in market prices of securities
     held. Such fluctuations are included with the net realized and unrealized
     gain or loss from investments. Net realized gains and losses on foreign
     currency transactions represent gains and losses on disposition of foreign
     currencies and forward foreign currency exchange contracts, currency gains
     and losses realized between the trade and settlement dates on securities
     transactions,  and the difference between the amount of investment income
     and foreign withholding taxes recorded on the Portfolio's books and the
     U.S. dollar equivalent amounts actually received or paid.

     C. INCOME TAXES

     The Portfolio is treated as a partnership for federal tax purposes. No
     provision is made by the Portfolio for federal or state taxes on any
     taxable income of the Portfolio because each investor in the Portfolio is
     ultimately responsible for the payment of any taxes. Since at least one of
     the Portfolio's investors is a regulated investment company that invests
     all or substantially all of its assets in the Portfolio, the Portfolio
     normally must satisfy the source of income and diversification requirements
     applicable to regulated investment companies (under the Internal Revenue
     Code) in order for its investors to satisfy them. The Portfolio allocates
     at least annually among its investors each investor's distributive share of
     the Portfolio's net investment income, net realized capital gains, and any
     other items of income, gain, loss deduction or credit.

     D. FOREIGN CURRENCY TRANSACTIONS

     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.

                                       28



                  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.

     E. INVESTMENT RISK

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

     F. EXPENSES

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

     G. COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the 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.

     H. AFFILIATED ISSUERS

     Affiliated issuers represent issuers in which the Portfolio held
     investments in other investment companies advised by Standish Mellon Asset
     Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of
     Mellon Financial Corporation, or its affiliates

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

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services 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, 2004. Pursuant to this agreement, for the year ended December
     31, 2004, Standish Mellon voluntarily did not impose $143,751 of its
     investment advisory fees. This agreement is voluntary and temporary and may
     be discontinued or revised by Standish Mellon at any time.

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio paid $69,985 during the year ended December
     31, 2004.

     The Fund entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement Mellon Bank receives an agreed upon percentage
     of the net lending revenues. This compensation is a standard form of
     compensation received by securities lending agents with respect to
     non-affiliated entities. See Note 6 for further details.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the Trustees.

(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Portfolio Trust's registration statement.

     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 options is shown
     in the Schedule of Investments. This amount reflects each contract's
     exposure to the underlying instrument at period end. Losses may arise from
     changes in the value of the underlying instruments if there is an illiquid
     secondary market for the contract or if the counterparty does not perform
     under the contract's terms.

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

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

     The Portfolio did not enter into any option transactions during the year
     ended December 31, 2004.

     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

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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.

     The Portfolio held foreign currency exchange contracts at December 31,
     2004. See 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 and credit
     default 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. 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 from
     market makers and 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 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 or loss. Entering into these agreements involves,
     to varying degrees, elements of credit, market, and documentation risk in
     excess of the amounts recognized on 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, 2004 the Portfolio held swap contracts. See 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, 2004
     resulting in $16,920 of security lending income. At December 31, 2004, the
     Portfolio had securities valued at $7,043,099 on loan. See the Statement 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

                                       31

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Portfolio as an unrealized gain or loss. If the TBA sale commitment is
     closed through the acquisition of an offsetting purchase commitment, the
     Portfolio realizes a gain or loss from the sale of the securities based
     upon the unit price established at the date the commitment was entered
     into. See Schedule of Investments for further details.

(8)  CONCENTRATION OF RISK:

     The Portfolio invests in low rated (non-investment grade) and comparable
     quality unrated high yield securities. Investments in high yield securities
     are accompanied by a greater degree of credit risk and the value of high
     yield securities tends to be more sensitive to economic conditions than
     higher rated securities. The risk of loss due to default of an issuer may
     be significantly greater for holders of high yield securities, because such
     securities are generally unsecured and are often subordinated to other
     creditors of the issuer.

     There are certain additional considerations and risks associated with
     investing in foreign securities and currency transactions that are not
     inherent with investments of domestic origin. The Portfolio's investment in
     emerging market countries may involve greater risks than investments in
     more developed markets and the price of such investments may be volatile.
     These risks of investing in foreign and emerging markets may include
     foreign currency exchange rate fluctuations, perceived credit risk, adverse
     political and economic developments and possible adverse foreign government
     intervention.

(9)  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 daily unused portion of the facility, is allocated ratably among the
     participating portfolios/funds at the end of each quarter. For the year
     ended December 31, 2004, a facility fee of $1,817 was allocated to the
     Portfolio.

     During the year ended December 31, 2004, the Portfolio had average
     borrowings outstanding of $30,667 on a total of nine days and incurred  $13
     of interest expense.

     To the Trustees of 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,
     2004, and the results of its operations, the changes in its net assets, and
     the financial highlights for each of the periods indicated, 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, 2004
     by correspondence with the custodian and brokers, provide a reasonable
     basis for our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.

The year was largely positive for the financial markets, as the economic
expansion continued. However,  as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point  in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

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

Sincerely,

Patrick J. Sheppard

                                  INCOME FUND

                      MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

Economic activity maintained a healthy pace in 2004. The employment picture
improved with monthly job gains averaging approximately 185,000. Investment
spending and capacity utilization picked up and despite higher interest rates,
the housing market and consumer spending kept pace. Amid rising oil prices and a
weaker dollar, the Federal Reserve maintained a tame inflation outlook. Bond
market volatility was low as the Fed hiked interest rates in a predictable and
steady fashion from 1% to 2.25% by the end of the year.  The unusual aspect of
this tightening cycle has been the decline in 10- and 30-year yields as short
rates have risen. So while the yield curve has flattened similarly to previous
cycles, long-term interest rates have moved to lower levels than expected. To a
large degree, the massive foreign purchases of U.S. Treasuries have kept
long-term interest rates lower than anticipated during a period of tighter
monetary policy.

Over the past year, broad sectors outperformed Treasuries with particularly
strong excess returns from investment grade corporate bonds. Spread sectors,
especially mortgages, benefited from declining interest rate volatility. The
credit sector fared well amid steady economic activity. Treasury
inflation-protected securities (TIPS) outperformed nominal Treasuries as both
actual and expected levels of inflation rose.

The prospects for economic growth in 2005 are good. We expect reasonably strong
economic data will support continued rate hikes by the Fed. Under tighter
monetary conditions, we anticipate upward pressure on interest rates and a
flatter yield curve. With today's low volatility environment and narrow yield
spreads, many sectors appear overvalued.

For the year, performance for the fund was 1.03% versus the Merrill Lynch 1-3
year Treasury benchmark of 0.91%. Performances for the fund and its benchmark
were negatively impacted by the increase in short-term interest rates throughout
the year. Although long-term interest rates ended the year near where they
began, short-term interest rates rose 125 basis points, in line with the Fed's
actions. The fund outperformed its benchmark for the year due primarily to the
fact that, for most of the year, its duration was 10 to 20 basis points shorter
than its benchmark. This duration difference was consistent with our belief that
the Fed would raise rates. In addition, the fund was able to take advantage of
spread product, such as corporate notes and asset-backed securities which are
not represented in its Treasury-based benchmark.

                          SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

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, 2004 to December 31, 2004).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

(a)  The Fund has adopted the provisions of the revised AICPA Audit and
Accounting Guide for Investment Companies effective January 1, 2001 and began
amortizing premium and discount on all debt securities on an effective yield
basis. The effect of this change for the year ended December 31, 2001 was to
increase net investment income per share by less than $0.001, decrease net
realized and unrealized gains and losses per share by less than $0.001 and
increase the ratio of net investment income to average net assets by less than
0.01%. Per share data and ratios/supplemental data for the periods prior to
January 1, 2001 have not been restated to reflect this change in presentation.

(1)  Calculated based on average shares outstanding,
(2)  The amount shown for a share outstanding does not correspond with the
aggregate net realized and unrealized gain/loss for the period due to the timing
of purchases and redemptions of Fund shares in relation to the fluctuating
market values of the Fund.
(+)     Total return would have been lower in the absence of expense waivers.

 MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST STANDISH MELLON SHORT-TERM FIXED
                                  INCOME FUND

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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 Short-Term Fixed Income Fund (the "Fund") is a separate
     diversified investment series of the Trust.

     The objective of the Fund is to maximize total return, consistent with
     preserving principal and liquidity, while seeking a relatively high level
     of current income. The Fund seeks to achieve its objective by investing,
     under normal circumstances, at least 80% of net assets in fixed income
     securities of U.S. companies and the U.S. government.

     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 for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     are valued at amortized cost, which approximates market value. If the Fund
     acquires a short-term instrument with more than sixty days remaining to its
     maturity, it is valued at current market value until the sixtieth day prior
     to maturity and will then be valued at amortized value based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized value 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 accrued, 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

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income and distributions from capital gains,
     if any, are reinvested in additional shares of the Fund unless a
     shareholder elects to receive them in cash. Income and capital gain
     distributions are determined in accordance with income tax regulations
     which may differ from accounting principles generally accepted in the
     United States of America. These differences, which may result in
     distribution reclassifications, are primarily due to differing treatments
     of amortization and/or accretion of premiums and discounts on certain
     securities and paydown gains and losses.

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

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

     D. EXPENSES

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

     E. COMMITMENTS AND CONTINGENCIES

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

     F. AFFILIATED ISSUERS

     Affiliated issuers represent investments held in the Fund in other
     investment companies advised by Standish Mellon Asset Management Company
     LLC ("Standish Mellon"), a wholly-owned subsidiary of Mellon Financial
     Corporation, or its affiliates.

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

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory, administrative services, and general office facilities, is paid
     monthly at the annual rate of 0.30% 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
     0.30% of the Fund's average daily net assets for the year ended December
     31, 2004. Pursuant to this agreement, for the year ended December 31, 2004,
     Standish Mellon collectively and voluntarily waived its investment advisory
     fee in the amount of $10,924 and reimbursed the Fund for $93,127 of its
     operating expenses. This agreement is voluntary and temporary and may be
     discontinued or revised by Standish Mellon at any time.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per
     account and transaction based fees, as well as, out-of-pocket expenses.
     Pursuant to this agreement the Fund paid $2,382 during the period ended
     December 31, 2004.

     The Fund has contracted Mellon Bank, N.A. ("Mellon Bank"), a wholly owned
     subsidiary of Mellon Financial Corporation and an affiliate of Standish
     Mellon, to provide custody, fund administration and 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 paid $31,369 during the year
     ended December 31, 2004.

     The Fund entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement Mellon Bank receives an agreed upon percentage
     of the net lending revenues. This compensation is a standard form of
     compensation received by securities lending agents with respect to
     non-affiliated entities.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, excluding short-term
     securities, for the year ended December 31, 2004 were as follows:


                                                                        PURCHASES                SALES

(4)  SHARES OF BENEFICIAL INTEREST:

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

     At December 31, 2004, two shareholders of record held approximately 83% of
     the total outstanding shares of the Fund. Investment activity of these
     shareholders could have a material impact on the Fund.

     A significant portion of the Fund's shares represent investments by
     fiduciary accounts over which Standish Mellon and its affiliates have
     either sole or joint investment discretion.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes all of its taxable income for its fiscal year.

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2004, was as follows:

     Unrealized appreciation                        $     15,126
     Unrealized depreciation                            (19,574)
                                                      __________
     Net unrealized appreciation/depreciation            (4,448)
     Cost for federal income tax purposes             $4,138,935

    Tax character of distributions paid during the fiscal year ended December
     31, 2004 and December 31, 2003, were as follows:


                                                                                2004                   2003

(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     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 securities 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 writte

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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 options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     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 writer of
     an option, has no control over whether the underlying securities may be
     sold (call) or purchased (put) and as a result bears the market risk of an
     unfavorable change in the price of the security underlying the written
     option.

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

     The Fund did not enter into any option contracts during the year ended
     December 31, 2004.

     FUTURES CONTRACTS

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

     The Fund did not enter into any futures contracts during the year ended
     December 31, 2004.

(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, 2004
     resulting in security lending income of $514. At December 31, 2004, the
     Fund had no securities on loan.

(8)  LINE OF CREDIT:

     The Fund, and other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio Trust (the "Portfolio 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 .060 of 1% committed amount,
     is allocated ratably among the participating portfolios/funds at the end of
     each quarter. For the year ended December 31, 2004, the facility fee
     allocated to the Fund was $40.

     During the year ended December 31, 2004, the Fund did not borrow under the
     credit facility.

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon Short-Term 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 Short-Term Fixed Income Fund (the "Fund") at December 31,
     2004, and the results of its operations, the changes in its net assets, and
     the financial highlights for each of the periods indicated, 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, 2004 by correspondence
     with the custodian and brokers, provide a reasonable basis for our opinion

February 28, 2005

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.

The year was largely positive for the financial markets, as the economic
expansion continued. However, as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its' 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

                       MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

Global bond markets produced modest, positive returns in 2004. The Standish
Mellon Global Fixed Income Fund returned 4.98% for the year, after all expenses,
compared to a return of 4.90% for the Lehman Global Aggregate Hedged Index.

A return of close to 5% for hedged global bonds is perhaps surprising
considering that at the beginning of the year, the consensus expectation was
that bond yields would rise as central banks raised interest rates. Indeed, bond
yields did rise early in the year and in particular the U.S. bond market
experienced a vicious sell-off in the first half. However, as the year
progressed, it became apparent that core inflation was well contained in the
U.S., the job market strengthened but not as much as anticipated, and growth in
large economies overseas was anemic. Bond yields fell during the second half of
the year, and in the end, despite the volatility, bond investors managed to earn
a bit more than their coupon.

The non-government sectors of the global bond markets were a pleasant surprise
producing returns well above government bonds for the second year in a row. The
star performers were corporate bonds, particularly the high-yield sector, and
emerging markets. A number of factors contributed to the outperformance of the
corporate and emerging sectors particularly global growth, low inflation, low
interest rates and in the case of the commodity laden emerging markets, high
commodity prices. The high yield corporate and emerging market indices both had
returns of over 10% for the year. Other non-government sectors also performed
well including mortgages, agencies and asset-backed securities.

The range of returns in hedged terms for government bond markets as measured by
the JP Morgan Government Bond Indices was modest for the year with only 534
basis points, separating the best market Italy (+8.00%) from the worst, Japan
(+2.66%). The U.S. component of the index returned 3.75% while European markets
returned 6.77% on average. The U.S. dollar had traded in a modest range for most
of the year however it fell sharply in the final quarter. The decline of the
dollar was the sharpest relative to the European currencies against which it
declined by more than 7%. The U.S. dollar has been under pressure since 2002 as
the mix of loose fiscal and monetary policy and the large current account
deficit made the currency unattractive to global investors.

The Fund outperformed its benchmark during the year. Our position in investment
grade and high yield corporate bonds and emerging market securities was the
largest positive contributor relative to our benchmarks. Our country selection
was also positive as we were overweight European markets, which produced the
best returns. Although Japan was the worst performing market in the index, our
zero weighting in the market was a slight drag on performance as Japan did
produce a positive return. In currencies, our small primarily, option-based
positions detracted a modest amount from our performance.

Our outlook for 2005 is favorable for global bonds. We believe that the
performance of global economies will be close to trend, yet the behavior of
central banks around the world could be quite different. The Fed will continue
to raise interest rates at least in the first half of the year and this will
flatten the yield curve but we expect longer dated bonds to be fairly stable.
Opportunities for value-added can be found in Europe and


                                       2


in some of the smaller index components such as Australia, New Zealand and the
U.K. In the latter three markets, the central banks have been raising interest
rates for some time and those increases now appear to be having an effect. These
economies have housing markets that are vulnerable to price declines and if the
economies soften, we believe bonds in these markets will perform well.
Non-government sectors such as corporate and emerging market bonds have richened
quite a bit over the past two years and we believe that these sectors will not
perform as well as in the past but that the sector still offers opportunities to
add-value through security selection.

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

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

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, 2004 to December 31, 2004).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

(a)  Through its investment in the Portfolio, the Fund has adopted the
     provisions of the revised AICPA Audit and Accounting Guide for Investment
     Companies effective January 1, 2001 and began amortizing premium and
     discount on all debt securities on an effective yield basis. The effect of
     this change for the year ended December 31, 2001 was to decrease net
     investment income per share by $0.007, increase net realized and unrealized
     gains and losses per share by $0.007 and decrease the ratio of net
     investment income to average net assets from 4.50% to 4.46%. Per share data
     and ratios/supplemental data for the periods prior to January 1, 2001 have
     not been restated to reflect this change in presentation.

     aggregate net realized and unrealized gain/loss for the period due to the
     timing of purchases and redemptions of Fund shares in relation to the

MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST STANDISH MELLON GLOBAL FIXED INCOME
                                     FUND

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

     The objective of the Fund is to maximize total return while realizing a
     market level of income consistent with preserving principal and liquidity.
     The Fund seeks to achieve its objective by investing all of its investable
     assets in an interest of Standish Mellon Global Fixed Income Portfolio (the
     "Portfolio"), a subtrust of the Mellon Institutional Funds Master Portfolio
     (the "Portfolio Trust"), which is organized as a New York trust and which
     has the same investment objective as the Fund. The Portfolio seeks to
     achieve its investment objective by investing, under normal circumstances,
     at least 80% of its net assets in U.S. and non-U.S. dollar denominated
     fixed income securities of U.S. and foreign governments and companies
     located in the U.S. and 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 (approximately
     100% at December 31, 2004). The performance of the Fund is directly
     affected by the performance of the Portfolio. The financial statements of
     the Portfolio are included elsewhere in this report and should be read in
     conjunction with the Fund's financial statements.

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

     A. INVESTMENT SECURITY VALUATIONS

     The Fund records its investment in the Portfolio at value. The method by
     which the Portfolio values its securities is discussed in Note 1A of the
     Portfolio's Notes to Financial Statements, which are included elsewhere in
     this report.

     B. SECURITIES TRANSACTIONS AND INCOME

     Transactions of the Portfolio are recorded as of the trade date. The Fund's
     net investment income consists of the Fund's pro rata share of the net
     investment income of the Portfolio, less all actual and accrued 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 Portfolio are allocated pro rata among the investors in
     the Portfolio.

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. In determining the amounts of its dividends,
     the Fund will take into account its share of the income, gains or losses,
     expenses, and any other tax items of the Portfolio. Dividends from net
     investment income and distributions from capital gains, if any, are
     reinvested in additional shares of the Fund unless a shareholder elects to
     receive them in cash. Income and capital gain distributions are determined
     in accordance with income tax regulations which may differ from accounting
     principles generally accepted in the United States of America. These
     differences, which may result in distribution reclassifications, are
     primarily due to differing treatments for losses deferred due to wash
     sales, foreign currency gains and losses, post-October losses, amortization
     and/or accretion of premiums and discounts on certain securities and the
     timing of recognition of gains and losses on futures contracts.

     Permanent book and tax basis differences will result in reclassifications
     to undistributed net investment income, accumulated net realized gain
     (loss) and paid in capital. Undistributed net investment income and
     accumulated net realized gain (loss) on investments and foreign currency
     transactions 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 are allocated taking into
     consideration, among other things, the nature and type of expense and the
     relative size of the funds or portfolios.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                    STANDISH MELLON GLOBAL FIXED INCOME 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.

(2)  INVESTMENT ADVISORY FEE AND 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 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. This agreement
     is voluntary and temporary and may be discontinued or revised by Standish
     Mellon at any time. Pursuant to this agreement, for the year ended December
     31, 2004, Standish Mellon voluntarily reimbursed the Fund for $31,222 of
     its operating expenses.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per
     account and transaction based fees, as well as, out-of-pocket expenses.
     Pursuant to this agreement the Fund paid $4,889 during the period ended
     December 31, 2004.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended December 31, 2004, aggregated $8,539,443and $93,677,645
     respectively.

(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, 2004, two shareholders of record held approximately 69% of
     the total outstanding shares of the Fund. Investment activity of these
     shareholders could have a material impact on the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

     As of December 31, 2004, the components of distributable earnings on a tax
     basis were as follows:


                                              AMOUNT
                                           ------------
                                         
                  Capital loss carryovers   $22,396,767


     At December 31, 2004, the Fund, for federal income tax purposes, has
     capital loss carry overs of $22,396,767 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
             -------------               -----------------

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     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, 2004, and the results of its operations, the changes in its
     net assets and the financial highlights for each of the periods indicated,
     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, 2004 to the Portfolio's records, provide a reasonable basis
     for our opinion.

(a)  The Portfolio has adopted the provisions of the revised AICPA Audit and
     Accounting Guide for Investment Companies effective January 1, 2001 and
     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to decrease the ratio of the net investment income to
     average net assets from 4.53% to 4.49%. Ratios for the periods prior to
     January 1, 2001 have not been restated to reflect this change in
     presentation.
(+)  Total return for the Portfolio has been calculated based on the total
     return for the invested Fund, assuming all distributions were reinvested,
     and adjusted for the difference in expenses as set out in the notes to the
     financial statements.

                  STANDISH MELLON GLOBAL FIXED INCOME PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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. and non-U.S.
     dollar denominated fixed income securities of U.S. and foreign governments
     and companies located in the U.S. and various countries, including emerging
     markets.

     At December 31, 2004 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, 2004 was approximately 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 for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are normally traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

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

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of coupon interest accrued, adjusted for accretion
     of discount or amortization of premium using the yield - to - maturity
     method on long-term debt securities and short-term securities with greater
     than sixty days to maturity. Realized gains and losses from securities sold
     are recorded on the identified cost basis.The Fund does not isolate that
     portion of the results of operations resulting from changes in foreign
     exchange rates on investments from the fluctuations arising from changes in
     market prices of securities held. Such fluctuations are included with the
     net realized and unrealized gain or loss from investments. Net realized
     gains and losses on foreign currency transactions represent gains and
     losses on disposition of foreign currencies and forward foreign currency
     exchange contracts, currency gains and losses realized between the trade
     and settlement dates on securities transactions, and the difference between
     the amount of investment income and foreign withholding taxes recorded on
     the Fund's books and the U.S. dollar equivalent amounts actually received
     or paid.

     C. INCOME TAXES

     The Portfolio is treated as a partnership for federal tax purposes. No
     provision is made by the Portfolio for federal or state taxes on any
     taxable income of the Portfolio because each investor in the Portfolio is
     ultimately responsible for the payment of any taxes. Since at least one of
     the Portfolio's investors is a regulated investment company that invests
     all or substantially all of its assets in the Portfolio, the Portfolio
     normally must satisfy the source of income and diversification requirements
     applicable to regulated investment companies (under the Internal Revenue
     Code) in order for its investors to satisfy them. The Portfolio allocates
     at least annually among its investors each investor's distributive share of
     the Portfolio's net investment income, net realized capital gains, and any
     other items of income, gain, loss deduction or credit.

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     D. FOREIGN CURRENCY TRANSACTIONS

     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.

     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.

     E. INVESTMENT RISK

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

     F. EXPENSES

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

     G. 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.

     H. AFFILIATED ISSUERS

     Affiliated issuers represent issuers in which the Fund held investments in
     other investment companies advised by Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary Mellon Financial
     Corporation, or its affiliates.

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

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services is paid monthly at the annual rate of
     0.40% of the Portfolio's average daily net assets

     The Portfolio compensates Mellon Bank, N.A. ("Mellon Bank"), a wholly owned
     subsidiary of Mellon Financial Corporation, under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio paid $98,030 during the year ended December
     31, 2004.

     The Fund entered into an agreement with Mellon Bank, to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement the Mellon Bank, receives an agreed upon
     percentage of the net lending revenues. This compensation is a standard
     form of compensation received by securities lending agents with respect to
     non-affiliated entities. See Note 6 for further details.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the Trustees.

(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Portfolio Trust's registration statement.

     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 options is shown
     in the Schedule of Investments. This amount reflects each contract's
     exposure to the underlying instrument at period 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.

     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, 2004 the Portfolio held forward foreign currency exchange
     contracts. See Schedule of Investments for further details.

     FUTURES CONTRACTS

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

     At December 31, 2004 the Portfolio did not have any futures contracts
     outstanding.

                          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 and credit
     default 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. 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 from
     market makers and 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 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 or loss. Entering into these agreements involves,
     to varying degrees, elements of credit, market, and documentation risk in
     excess of the amounts recognized on 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, 2004 the Portfolio held swap contracts. See 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, 2004
     resulting in $9,485 of security lending income. At December 31, 2004, the
     Portfolio had securities valued at $1,911,153 on loan. See the Statement 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.

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Portfolio as an unrealized gain or loss. If the TBA sale commitment is
     closed through the acquisition of an offsetting purchase commitment, the
     Portfolio realizes a gain or loss from the sale of the securities based
     upon the unit price established at the date the commitment was entered
     into.

     At December 31, 2004 the Portfolio held delayed delivery securities. See
     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 daily unused portion of the facility, is allocated ratably among the
     participating portfolios/funds at the end of each quarter. For the year
     ended December 31, 2004, a facility fee of $1,227 was allocated to the
     Portfolio.

     During the year ended December 31, 2004, the Portfolio had average
     borrowings outstanding of $221,500 on a total of four days and incurred $68
     of interest expense.

     To the Trustees of 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, 2004, and the results of its operations, the changes in its net assets,
     and the financial highlights for each of the periods indicated, 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, 2004
     by correspondence with the custodian and brokers, provide a reasonable
     basis for our opinion.

February 28, 2005

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.

The year was largely positive for the financial markets, as the economic
expansion continued. However, as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

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

International bond markets produced modest, positive returns in 2004. The
Standish Mellon International Fixed Income Fund returned 4.88% for the year,
after all expenses, compared to a return of 5.21% for the J.P. Morgan Hedged
Non-U.S. Government Bond Index.

A return of close to 5% for hedged international bonds is perhaps surprising
considering that at the beginning of the year, the consensus expectation was
that bond yields would rise as central banks raised interest rates. Indeed, bond
yields did rise early in the year, and this rise was lead by the U.S. bond
market, which experienced a vicious sell-off in the first half. However, as the
year progressed, it became apparent that core inflation was well contained in
the U.S., the job market strengthened but not as much as anticipated, and growth
in large economies overseas was anemic. Bond yields in the U.S. and overseas
fell during the second half of the year, and in the end, despite the volatility,
bond investors managed to earn a bit more than their coupon.

The non-government sectors of the international bond markets were a pleasant
surprise, producing returns well above government bonds for the second year in a
row. The star performers were corporate bonds, particularly the high-yield
sector, and emerging markets. A number of factors contributed to the
outperformance of the corporate and emerging sectors, particularly global
growth, low inflation, low interest rates and in the case of the commodity laden
emerging markets, high commodity prices. The high yield corporate and emerging
market indices both had returns of over 10% for the year. Other non-government
sectors also performed well, including mortgages, agencies and asset-backed
securities.

The range of returns in hedged terms for government bond markets as measured by
the JP Morgan Government Bond Indices was modest for the year with only 534
basis points separating the best market, Italy, (+8.00%) from the worst, Japan
(+2.66%). The U.S. component of the index returned 3.75% while European markets
returned 6.77% on average. The U.S. dollar had traded in a modest range for most
of the year; however it fell sharply in the final quarter. The decline of the
dollar was the sharpest relative to the European currencies against which it
declined by more than 7%. The U.S. dollar has been under pressure since 2002 as
the mix of loose fiscal and monetary policy and the large current account
deficit made the currency unattractive to global investors.

The Fund underperformed its benchmark during the year. Our position in
investment grade and high yield corporate bonds and emerging market securities
was the largest positive contributor relative to our benchmark. The results of
our country weightings were mixed. We were overweight European markets, which
produced the best returns; however we had a zero weight in the Japanese bond
market which weighed on our performance. Although Japan was the worst performing
market in the index, our zero weighting in the market was a drag on performance
as Japan did produce a positive return. In currencies, our small primarily,
option-based positions detracted a modest amount from our performance.

                                       2


Our outlook for 2005 is favorable for international bonds. We believe that the
performance of global economies will be close to trend, yet the behavior of
central banks around the world could be quite different. We expect that the Fed
will continue to raise interest rates at least in the first half of the year and
this will flatten the yield curve but we expect longer dated bonds to be fairly
stable. Opportunities for value-added can be found in Europe and in some of the
smaller index components such as Australia, New Zealand and the U.K. In the
latter three markets, the central banks have been raising interest rates for
some time and those increases now appear to be having an effect. These economies
have housing markets that are vulnerable to price declines and, if the economies
soften, we believe bonds in these markets will perform well. Non-government
sectors such as corporate and emerging market bonds have richened quite a bit
over the past two years, and we believe that these sectors will not perform as
well as in the past but that the sector still offers opportunities to add-value
through security selection.

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

W. Charles Cook

                          SHAREHOLDER EXPENSE EXAMPLE

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, 2004 to December 31, 2004).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

*    The Fund has adopted the provisions of the revised AICPA Audit and
     Accounting Guide for Investment Companies effective January 1, 2001 and
     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31,2001 was to decrease net investment income per share by $0.007,
     increase net realized and unrealized gains and losses per share by $0.007
     and decrease the ratio of net investment income to average net assets from
     3.98% to 3.94%. Per share data and ratios/supplemental data for the periods
     prior to January 1, 2001 have not been restated to reflect this change in
     presentation.

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                STANDISH MELLON INTERNATIONAL FIXED INCOME FUND

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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.

     During the year ended December 31, 2004 the Fund had offered two classes of
     shares: Institutional Class and Service Class. On April 30, 2004 the
     Service Class was liquidated and closed. Expenses of the Fund, until the
     time when the Service Class was closed, were borne pro-rata by the holders
     of each class of shares, except for transfer agent fees and an account
     service fee of up to 0.25% of the average daily net assets of the Service
     Class of shares. Each class voted separately as a class only with respect
     to its own service plan (Service Class only) or other matters that relate
     only to that class. Shares of the Service Class received their pro-rata
     share of the net assets of the Fund (after satisfaction of any
     class-specific expenses) when the Service Class was liquidated.

     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. The
     Fund also invests, under normal circumstances, 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 for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     are valued at amortized cost, which approximates market value. If the Fund
     acquires a short-term instrument with more than sixty days remaining to its
     maturity, it is valued at current market value until the sixtieth day prior
     to maturity and will then be valued at amortized value based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized value 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 accrued, adjusted for
     accretion of discount or amortization of premium using the
     yield-to-maturity method on long-term debt securities and short-term
     securities of 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 Fund does not isolate
     that portion of the results of operations resulting from changes in foreign
     exchange rates on investments from the fluctuations arising from changes in
     market prices of securities held. Such fluctuations are included with the
     net realized and unrealized gain or loss from investments. Net realized
     gains and losses on foreign currency transactions represent gains and
     losses on disposition of foreign currencies and forward foreign currency
     exchange contracts, currency gains and losses realized between the trade
     and settlement dates on securities transactions, and the difference between
     the amount of investment income and foreign withholding taxes recorded on
     the Fund's books and the U.S. dollar equivalent amounts actually received
     or paid.

     C. FOREIGN CURRENCY TRANSACTIONS

     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.

     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. 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.

     E. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. Dividends from net investment income and
     distributions from capital gains, if any, are reinvested in additional
     shares of the Fund unless the shareholder elects to receive them in cash.
     Income and capital gain distributions are determined in accordance with
     income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in distribution reclassifications, are primarily due to
     differing treatments for losses deferred due to wash sales, foreign
     currency gains and losses, post-October losses, amortization and/or
     accretion of premiums and discounts on certain securities and the timing of
     recognition of gains and losses on futures contracts.

     Permanent book and tax basis differences relating to shareholder
     distributions will result in reclassifications among undistributed net
     investment income, accumulated net realized gain (loss) and paid in
     capital. Undistributed net investment income and accumulated net realized
     gain (loss) on investments and foreign currency transactions 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.

     F. EXPENSES

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

     G. COMMITMENTS AND CONTINGENCIES

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

     H. AFFILIATED ISSUERS

     Affiliated issuers represent issuers held in the Fund in other investment
     companies advised by Standish Mellon Asset Management Company LLC
     ("Standish Mellon"), a wholly-owned subsidiary Mellon Financial
     Corporation, or its affiliates.

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

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services, and general office facilities is paid
     monthly at the annual rate of 0.40% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit the Service Class operating
     expenses (excluding brokerage commissions, taxes and extraordinary
     expenses) for the year ended December 31, 2004, so that the Service Class
     annual operating expenses did not exceed the total operating expenses of
     the Institutional Class (net of any expense limitation) for the comparable
     period plus 0.25% (the maximum Service Fee). Pursuant to this agreement,
     for the year ended December 31, 2004, Standish Mellon reimbursed the
     Service Class $2,032 for class specific operating expenses.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per
     account and transaction based fees, as well as, out-of-pocket expenses.
     Pursuant to this agreement the Fund paid $16,638 during the period ended
     December 31, 2004.

A significant portion of the Fund's shares are beneficially owned by fiduciary
accounts over which Standish Mellon and its affiliates have either sole or joint
investment discretion. Investment activity 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 90 days from
the day of their purchase. The redemption fee is paid directly to the Fund, and
is designed to offset brokerage commissions, market impact, and other costs
associated with short-term trading in the Fund. The fee does not apply to shares
that are acquired through reinvestment of distributions. For the year ended
December 31, 2004, the Fund received $542 of redemption fees.

(5) FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes all of its taxable income for its fiscal year.

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2004, was as follows:


                                                              AMOUNT

     At December 31, 2004, the Fund, for federal income tax purposes, has
     capital loss carryovers of $52,478,133 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:

(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     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 securities 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 options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     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 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.

     December 31, 2004. The option transactions of the Fund were as follows:

     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.

     The Fund had entered into foreign currency exchange contracts during the
     year ended December 31, 2004. See Schedule of Investments for further
     details.

     FUTURES CONTRACTS

     The Fund may enter into financial futures contracts for the delayed sale or
     delivery of securities or contracts based on financial indices at a fixed
     price on a future date. Pursuant to the margin requirements, the Fund
     deposits either cash or securities in an amount equal to a certain
     percentage of the contract amount. Subsequent payments are made or received
     by the Fund each day, depending on the daily fluctuations in the value of
     the underlying security, and are recorded for financial statement purposes
     as unrealized gains or losses by the Fund. There are several risks in
     connection with the use of futures contracts as a hedging device. The
     change in value of futures contracts primarily corresponds with the value
     of their underlying instruments or indices, which may not correlate with
     changes in the value of hedged investments. Buying futures tends to
     increase the

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     Fund's exposure to the underlying instrument, while selling futures tends
     to decrease the Fund's exposure to the underlying instrument or hedge other
     Fund investments. In addition, there is the risk that the Fund may not be
     able to enter into a closing transaction because of an illiquid secondary
     market. Losses may arise if there is an illiquid secondary market or if the
     counterparties do not perform under the contract's terms. The Fund enters
     into financial futures transactions primarily to manage its exposure to
     certain markets and to changes in securities prices and foreign currencies.
     Gains and losses are realized upon the expiration or closing of the futures
     contracts. Futures contracts are valued at the quoted daily settlement
     prices established by the exchange on which they trade.

     The Fund had entered in to futures transactions during the year ended
     December 31, 2004. See 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 and credit default 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. 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 from market makers and 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 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 or loss. Entering into these
     agreements involves, to varying degrees, elements of credit, market, and
     documentation risk in excess of the amounts recognized on 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, 2004 the Fund held swap contracts. See 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, 2004
     resulting in security lending income of $17,062. At December 31, 2004, the
     Fund had securities valued at $5,048,081 on loan. See Schedule of
     Investments for further detail on the security positions on loan.

(8)  LINE OF CREDIT:

     The Fund, and other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio Trust (the "Portfolio 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 .060 of 1% committed amount,
     is allocated ratably among the participating portfolios/funds at the end of
     each quarter. For the year ended December 31, 2004, a facility fee of
     $4,670 was allocated to the Fund.

     During the year ended December 31, 2004, the Fund had average borrowings
     outstanding of $1,623,857 on a total of seven days and incurred $855 of
     interest expense.

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     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, 2004, and the results of its operations, the changes in its net assets,
     and the financial highlights for each of the periods indicated, 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, 2004 by correspondence
     with the custodian and brokers, provide a reasonable basis for our opinion

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.

The year was largely positive for the financial markets, as the economic
expansion continued. However, as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its' 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

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

Economic activity maintained a healthy pace in 2004. The employment picture
improved with monthly job gains averaging approximately 185,000. Investment
spending and capacity utilization picked up and despite higher interest rates,
the housing market and consumer spending kept pace. Amid rising oil prices and a
weaker dollar, the Federal Reserve maintained a tame inflation outlook. Bond
market volatility was low as the Fed hiked interest rates in a predictable and
steady fashion from 1% to 2.25% by the end of the year. The unusual aspect of
this tightening cycle has been the decline in 10- and 30-year yields as short
rates have risen. So while the yield curve has flattened similarly to previous
cycles, long-term interest rates have moved to lower levels than expected. To a
large degree, the massive foreign purchases of U.S. Treasuries have kept
long-term interest rates lower than anticipated during a period of tighter
monetary policy.

Over the past year, broad sectors outperformed Treasuries with particularly
strong excess returns from investment grade corporate bonds. Spread sectors,
especially mortgages, benefited from declining interest rate volatility. The
credit sector fared well amid steady economic activity. Treasury
inflation-protected securities (TIPS) outperformed nominal Treasuries as both
actual and expected levels of inflation rose.

The prospects for economic growth in 2005 are good. We expect reasonably strong
economic data will support continued rate hikes by the Fed. Under tighter
monetary conditions, we anticipate upward pressure on interest rates and a
flatter yield curve. With today's low volatility environment and narrow yield
spreads, many sectors appear overvalued.

Performance of the fund was negatively impacted by the increase in short-term
interest rates throughout the year. Performance for the fund was .75% for the
year versus the iMoneyNet benchmark of .78%. Although long-term interest rates
ended the year near where they began, short-term interest rates rose 125 basis
points, in line with the Fed's actions. The strategic duration target for the
fund is at approximately 1 year and the fund is marked to market. This
combination of a longer duration and mark-to-market accounting translates into a
performance disadvantage compared to a money market fund benchmark, which has a
much shorter duration and constant $1.00 NAV accounting. These negative factors
were partially offset by the long-term advantages of fund. By having a longer
strategic duration, the fund is able to move out on a normally positively sloped
yield curve. In addition, the fund is able to invest in a broader and better
yielding set of investments than those normally available to a money market
fund. As a result, performance for the fund for the year was only slightly below
its money market fund benchmark.

                           SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

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, 2004 to December 31, 2004).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

(a)  Through its investment in the Portfolio, the Fund has adopted the
     provisions of the revised AICPA Audit and Accounting Guide for Investment
     Companies effective January 1, 2001 and began amortizing premium and
     discount on all debt securities on an effective yield basis. The effect of
     this change for the year ended December 31, 2001 was to increase net
     investment income per share by $0.001, decrease net realized and unrealized
     gains and losses per share by $0.001 and increase the ratio of net
     investment income to average net assets by less than 0.01%. Per share data

                   MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST
                  STANDISH MELLON SHORT-TERM ASSET RESERVE FUND

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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 Short-Term Asset Reserve Fund (the "Fund") is a separate
     diversified investment series of the Trust.

     The objective of the Fund is to achieve a high level of current income
     consistent with preserving principal and liquidity. The Fund seeks to
     achieve its objective by investing all of its investable assets in an
     interest of the Standish Mellon Short-Term Asset Reserve Portfolio (the
     "Portfolio"), a subtrust of Mellon Institutional Funds Master Portfolio
     (the "Portfolio Trust"), which is organized as a New York trust and which
     has the same investment objective as the Fund. The Portfolio seeks to
     achieve its objective by investing, under normal circumstances, at least
     80% of net assets in 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 (approximately 100% at December 31, 2004).
     The performance of the Fund is directly affected by the performance of the
     Portfolio. The financial statements of the Portfolio are included elsewhere
     in this report and should be read in conjunction with the Fund's financial
     statements.

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

     A. INVESTMENT SECURITY VALUATIONS

     The Fund records its investment in the Portfolio at value. The method by
     which the Portfolio values its securities is discussed in Note 1A of the
     Portfolio's Notes to Financial Statements, which are included elsewhere in
     this report.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions of the Portfolio are recorded as of the trade date.
     Currently, the Fund's net investment income consists of the Fund's pro rata
     share of the net investment income of the Portfolio, less all actual and
     accrued 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 Portfolio are allocated pro rata
     among the investors in the Portfolio.

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared daily and distributed
     monthly. The Fund's dividends from short-term and long-term capital gains,
     if any, after reduction of capital losses will be declared and distributed
     at least annually. In determining the amounts of its dividends, the Fund
     will take into account its share of the income, gains or losses, expenses,
     and any other tax items of the Portfolio. Dividends from net investment
     income and distributions from capital gains, if any, are reinvested in
     additional shares of the Fund unless a shareholder elects to receive them
     in cash. Income and capital gain distributions are determined in accordance
     with income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in distribution reclassifications, are primarily due to
     differing treatments for capital loss carryforwards and amortization and/or
     accretion of premiums and discounts on certain securities.

     Permanent book and tax basis differences will result in reclassifications
     to undistributed net investment income, accumulated net realized gain
     (loss) and paid in capital. Undistributed net investment income and
     accumulated net realized gain (loss) on investments and foreign currency
     transactions 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 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.

(2)  INVESTMENT ADVISORY FEE AND TRANSACTIONS WITH AFFILIATES:

     The Fund does not directly pay any investment advisory fees, but indirectly
     bears its pro rata share of the compensation paid by the Portfolio to
     Standish Mellon Asset Management Company LLC ("Standish Mellon"), a
     wholly-owned subsidiary Mellon Financial Corporation, for such services.
     See Note 2 of the Portfolio's Notes to Financial Statements which are
     included elsewhere in this report. Standish Mellon voluntarily agreed to
     limit the total operating expenses of the Fund and its pro rata share of
     the Portfolio expenses (excluding brokerage commissions, taxes and
     extraordinary expenses) to 0.45% of the Fund's average daily net assets for
     the year ended December 31,2004. Pursuant to these agreements, for the year
     ended December 31, 2004, Standish Mellon voluntarily reimbursed the Fund
     for $55,494 of its operating expenses. This agreement is voluntary and
     temporary and may be discontinued or revised by Standish Mellon at any
     time.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per
     account and transaction based fees as well as out-of-pocket expenses.
     Pursuant to this agreement the Fund paid $6,756 during the period ended
     December 31, 2004.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended December 31, 2004, aggregated $63,157,972 and $138,574,542,
     respectively.

(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, 2004, one shareholder of record held approximately 14% of
     the total outstanding shares of the Fund. Investment activity of this
     shareholder could have a material impact on the Fund.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

     As of December 31, 2004 and December 31, 2003, the components of
     distributable earnings on a tax basis were as follows:



                                                       2004
                                                    ------------
                                                 
                 Undistributed ordinary income      $     1,458
                 Capital loss carry forward          (2,356,373)


     At December 31, 2004, the Fund, for federal income tax purposes, has
     capital loss carryovers of $2,356,373 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
              ------------                ----------------

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon Short-Term Asset Reserve 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 Short-Term Asset Reserve Fund (the
     "Fund") at December 31, 2004, and the results of its operations, the
     changes in its net assets and the financial highlights for each of the
     periods indicated, in conformity with accounting principles generally
     accepted in the United States of America. These financial statements and
     the 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,
     2004 to the Portfolio's records, provide a reasonable basis for our
     opinion.

(a) The Portfolio has adopted the provisions of the revised AICPA Audit and
Accounting Guide for Investment Companies effective January 1, 2001 and began
amortizing premium and discount on all debt securities on an effective yield
basis. The effect of this change for the year ended December 31, 2001 was to
increase the ratio of the net investment income to average net assets by less
than 0.01%. Ratios for the periods prior to January 1, 2001 have not been
restated to reflect this change in presentation.

(+) Total return for the Portfolio has been calculated based on the total return
for the invested Fund, assuming all distributions were reinvested, and adjusted
for the difference in expenses as set out in the notes to the financial
statements. Total return would have been lower in the absence of expense
waivers.

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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 Short-Term Asset Reserve Portfolio (the "Portfolio") is a separate
     diversified investment series of the Portfolio Trust.

     At December 31, 2004 there was one fund, Standish Mellon Short-Term Asset
     Reserve 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, 2004 was approximately 100%.

     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.

     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 for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are normally traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

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

     B. SECURITIES TRANSACTIONS AND INCOME

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

     C. INCOME TAXES

     The Portfolio is treated as a partnership for federal tax purposes. No
     provision is made by the Portfolio for federal or state taxes on any
     taxable income of the Portfolio because each investor in the Portfolio is
     ultimately responsible for the payment of any taxes. Since at least one of
     the Portfolio's investors is a regulated investment company that invests
     all or substantially all of its assets in the Portfolio, the Portfolio
     normally must satisfy the source of income and diversification requirements
     applicable to regulated investment companies (under the Internal Revenue
     Code) in order for its investors to satisfy them. The Portfolio allocates
     at least annually among its investors each investor's distributive share of
     the Portfolio's net investment income, net realized capital gains, and any
     other items of income, gain, loss deduction or credit.

     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 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 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.

     F. AFFILIATED ISSUERS

     Affiliated issuers represent investments held in the Portfolio in other
     investment companies advised by Standish Mellon Asset Management Company
     LLC ("Standish Mellon"), a wholly-owned subsidiary Mellon Financial
     Corporation, or its affiliates.

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

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory and administrative services is paid monthly at the annual rate of
     0.25% of the Portfolio's average daily net assets.

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio paid $77,893 during the year ended December
     31, 2004.

     The Fund entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement Mellon Bank receives an agreed upon percentage
     of the net lending revenues. This compensation is a standard form of
     compensation received by securities lending agents with respect to
     non-affiliated entities.For further details see Note 6.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the 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, 2004 were as follows:




                                            PURCHASES            SALES
                                          ----------         ----------
                                                      
     U.S. Government Securities          $10,285,317        $16,873,386
                                          ==========         ==========
     Investments (non-U.S.
     Government Securities)            $24,208,797        $68,625,142
                                          ==========         ==========

(4)  FEDERAL TAXES:

     The cost and unrealized appreciation (depreciation) in value of the
     investment securities owned at December 31, 2004, as computed on a federal
     income tax basis, were as follows:



                                      
     Aggregate Cost                      $69,536,010

     Net unrealized depreciation        $   (131,398)
                                          ==========

(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Portfolio Trust's registration statement.

                                       22


                  MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
              STANDISH MELLON SHORT-TERM ASSET RESERVE PORTFOLIO

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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 options is shown
     in the Schedule of Investments. This amount reflects each contract's
     exposure to the underlying instrument at period end. Losses may arise from
     changes in the value of the underlying instruments if there is an illiquid
     secondary market for the contract or if the counterparty does not perform
     under the contract's terms.

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

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

     The Portfolio did not enter into any option transactions during the year
     ended December 31, 2004.

     INTEREST RATE FLOORS

     Interest rate floors purchased by the Portfolio entitle the Portfolio to
     receive payments on a notional principal amount from the party selling such
     floor to the extent that a specified index falls below a predetermined
     interest rate amount. Credit and market risk exist with respect to these
     instruments. If forecasts of interest rates and other market factors are
     incorrect, investment performance will diminish compared to what
     performance would have been if these investment techniques were not used.
     Even if the forecasts are correct, there are risks that the positions may
     correlate imperfectly with the asset or liability being hedged, a liquid
     secondary market may not always exist, or a counterparty to a transaction
     may not perform. The Portfolio expects to enter these transactions
     primarily for hedging purposes including, but not limited to, preserving a
     return or spread on a particular investment or portion of its portfolio,
     protecting against interest rate fluctuations, as a duration management
     technique or protecting against an increase in the price of securities the
     Portfolio anticipates purchasing at a later date. Interest rate floors are
     "marked-to-market" daily based on quotations from market makers and the
     change, if any, is recorded as unrealized appreciation or depreciation in
     the Statement of Operations. Periodic payments of interest, if any, are
     reported as additions to interest income in the Statement of Operations.
     Realized gains or losses from these agreements are disclosed in the
     Statement of Operations.

     The Portfolio did not enter into any open interest rate floor agreements
     during the year ended December 31, 2004.

     FUTURES CONTRACTS

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

                                       23

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     At December 31, 2004, the Portfolio held financial futures contracts. At
     December 31, 2004, the Portfolio had segregated sufficient cash and/or
     securities to cover margin requirements on open futures contracts. See
     Schedule of Investments for further detail.

(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, 2004
     resulting in $1,351 of security lending income. At December 31, 2004, the
     Portfolio had securities valued at $1,679,767 on loan. See the Statement 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.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Portfolio as an unrealized gain or loss. If the TBA sale commitment is
     closed through the acquisition of an offsetting purchase commitment, the
     Portfolio realizes a gain or loss from the sale of the securities based
     upon the unit price established at the date the commitment was entered
     into.

     At December 31, 2004, the Portfolio did not have any delayed delivery
     transactions.

(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 daily unused portion of the facility, is allocated ratably among the
     participating portfolios/funds at the end of each quarter. For the year
     ended December 31, 2004, a facility fee of $1,515 was allocated to the
     Portfolio.

     During the year ended December 31, 2004, the Portfolio had average
     borrowings outstanding of $219,500 on a total of six days and incurred $90
     of interest expense.

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

     To the Trustees of Mellon Institutional Funds Master Portfolio and
     Investors of the Standish Mellon Short-Term Asset Reserve 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 Short-Term Asset Reserve Portfolio (the "Portfolio") at
     December 31, 2004, and the results of its operations, the changes in its
     net assets, and the financial highlights for each of the periods indicated,
     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, 2004
     by correspondence with the custodian and brokers, provide a reasonable
     basis for our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.

The year was largely positive for the financial markets, as the economic
expansion continued. However, as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its' 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

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

                        STANDISH MELLON FIXED INCOME FUND

                      MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

Economic activity maintained a healthy pace in 2004. The Standish Mellon Fixed
Income Fund returned 5.74% for the year 2004 while the Lehman Brothers Aggregate
Index returned 4.34% for the same period.

The employment picture improved with monthly job gains averaging approximately
185,000. Investment spending and capacity utilization picked up and despite
higher interest rates, the housing market and consumer spending kept pace. Amid
rising oil prices and a weaker dollar, the Federal Reserve maintained a tame
inflation outlook. Bond market volatility was low as the Fed hiked interest
rates in a predictable and steady fashion from 1% to 2.25% by the end of the
year. The unusual aspect of this tightening cycle has been the decline in 10-
and 30-year yields as short rates have risen. So while the yield curve has
flattened similarly to previous cycles, long-term interest rates have moved to
lower levels than expected. To a large degree, the massive foreign purchases of
U.S. Treasuries have kept long-term interest rates lower than anticipated during
a period of tighter monetary policy.

Over the past year, broad sectors outperformed Treasuries with particularly
strong excess returns from high yield corporate bonds. Spread sectors,
especially mortgages, benefited from declining interest rate volatility.
Investment grade and lower quality corporate bonds fared well amid steady
economic activity. International bonds outperformed as Europe's lagging economic
growth resulted in lower European yields relative to the U.S. Over the course of
the year, the primary sources of outperformance were the overweight positions in
corporate and non-U.S. bonds, as well as the defensive yield curve strategy. As
the yield curve flattened, the Fund's underweight position in intermediate bonds
(bullet strategy) relative to cash and longer maturities (barbell strategy)
benefited returns. Portfolio positioning also capitalized on the lower
volatility environment with an increased allocation to mortgages. Toward
year-end, we took some profits in the non-dollar position. Similarly, with much
narrower corporate bond spreads, we selectively reduced the Fund's credit
exposure in both the high yield and investment grade corporate sectors.

The prospects for economic growth in 2005 are good. We expect reasonably strong
economic data will support continued rate hikes by the Fed. Under tighter
monetary conditions, we anticipate upward pressure on interest rates and a
flatter yield curve. With today's low volatility environment and narrow yield
spreads, many sectors appear overvalued. Given the vulnerability to a correction
in spread sectors, we have positioned the Fund defensively, particularly with a
reduced corporate bond position. We have increased our allocation to Treasury
inflation-protected securities (TIPS) as seasonal inflation patterns and
breakeven inflation rates in the area of 2.5% make TIPS attractive relative to
nominal Treasuries. With weaker European growth prospects, we anticipate rising
U.S. rates relative to Europe which will benefit the remaining international
position. Ultimately, if as we expect, the Fed maintains their tightening
stance, the Fund's shorter than benchmark duration and barbell curve position
will continue to contribute positively to performance.

As always, we look forward to serving you in the coming year.

                          SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

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 (April 1, 2004 to September 30, 2004).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

(a) The Fund has adopted the provisions of the revised AICPA Audit and
Accounting Guide for Investment Companies effective January 1, 2001 and began
amortizing premium and discount on all debt securities on an effective yield
basis. The effect of this change for the year ended December 31, 2001 was to
decrease net investment income per share by $0.004, increase net realized and
unrealized gains and losses per share by $0.004 and decrease the ratio of net
investment income to average net assets from 6.37% to 6.35%. Per share data and
ratios/supplemental data for the periods prior to January 1, 2001 have not been
restated to reflect this change in presentation.

(1) Calculated based on average shares outstanding. (2) Includes the Fund's
share of the Portfolio's allocated expenses. (+) Total return would have been
lower in the absence of expense waivers.

                       STANDISH MELLON FIXED INCOME FUND

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  SIGNIFICANT ACCOUNTING POLICIES:

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

     The objective of the Fund is to achieve a high level of current income,
     consistent with conserving principal and liquidity, and secondarily to seek
     capital appreciation when changes in interest rates and economic conditions
     indicate that capital appreciation may be available without significant
     risk to principal. The Fund seeks to achieve its objective by investing all
     of its investable assets in an interest of the 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 which has the same investment objective as the Fund. The
     Portfolio seeks to achieve its objective by investing, under normal
     circumstances, at least 80% of net assets in 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 (approximately 100% at December 31, 2004).
     The performance of the Fund is directly affected by the performance of the
     Portfolio. The financial statements of the Portfolio are included elsewhere
     in this report and should be read in conjunction with the Fund's financial
     statements.

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

     A. INVESTMENT SECURITY VALUATIONS

     The Fund records its investment in the Portfolio at value. The method by
     which the Portfolio values its securities is discussed in Note 1A of the
     Portfolio's Notes to Financial Statements, which are included elsewhere in
     this report.

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions in the Portfolio are recorded as of the trade date.
     Currently, the Fund's net investment income consists of the Fund's pro rata
     share of the net investment income of the Portfolio, less all actual and
     accrued 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 Portfolio are allocated pro rata
     among the investors in the Portfolio.

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared daily and distributed
     monthly. The Fund's dividends from short-term and long-term capital gains,
     if any, after reduction of capital losses will be declared and distributed
     at least annually. In determining the amounts of its dividends, the Fund
     will take into account its share of the income, gains or losses, expenses,
     and any other tax items of the Portfolio. Dividends from net investment
     income and distributions from capital gains, if any, are reinvested in
     additional shares of the Fund unless a shareholder elects to receive them
     in cash. Income and capital gain distributions are determined in accordance
     with income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in distribution reclassifications, are primarily due to
     differing treatments for capital loss carryforwards and amortization and/or
     accretion of premiums and discounts on certain securities.

     Permanent book and tax basis differences will result in reclassifications
     to undistributed net investment income, accumulated net realized gain
     (loss) and paid in capital. Undistributed net investment income and
     accumulated net realized gain (loss) on investments and foreign currency
     transactions 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 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.

(2)  INVESTMENT ADVISORY FEE AND 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.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per
     account and transaction based fees, as well as, out-of-pocket expenses.
     Pursuant to this agreement the Fund paid $19,762 during the period ended
     December 31, 2004.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the Trustees.

(3)  INVESTMENT TRANSACTIONS:

     Increases and decreases in the Fund's investment in the Portfolio for the
     year ended December 31, 2004, aggregated $65,727,299 and $238,255,854,
     respectively.

(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

(5) FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes substantially all of its taxable income for its
     fiscal year.

     As of December 31, 2004, the components of distributable earnings on a tax
     basis were as follows:



                                                          AMOUNT

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

     At December 31, 2004, the Fund, for federal income tax purposes, has
     capital loss carryovers of $185,181,079 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:

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     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, 2004, and the results of its operations, the changes in its
     net assets and the financial highlights for each of the periods indicated,
     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 invesment in the Portfolio at
     December 31, 2004, to the Portfolio's records, provide a reasonable basis
     for our opinion.

*  For the periods indicated, the investment adviser voluntarily agreed not to impose all or a portion of its investment
   advisory fee and/or reimbursed the Fund for a portion of its operating expenses. If this voluntary action had not been

(a)  The Portfolio has adopted the provisions of the revised AICPA Audit and
     Accounting Guide for Investment Companies effective January 1, 2001 and
     began amortizing premium and discount on all debt securities on an
     effective yield basis. The effect of this change for the year ended
     December 31, 2001 was to decrease the ratio of the net investment income to
     average net assets from 6.39% to 6.37%. Ratios for the periods prior to
     January 1, 2001 have not been restated to reflect this change in
     presentation.

(+)  Total return for the Portfolio has been calculated based on the total
     return for the invested Fund, assuming all distributions were reinvested,
     and adjusted for the difference in expenses as set out in the notes to the
     financial statements. Total return would have been lower in the absence of

                  MELLON INSTITUTIONAL FUNDS MASTER PORTFOLIO
                    STANDISH MELLON FIXED INCOME PORTFOLIO

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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.

     At December 31, 2004 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,
     2004 was approximately 100%.

     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.

     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 for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are normally traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

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

     B. SECURITIES TRANSACTIONS AND INCOME

     Securities transactions are recorded as of trade date. Interest income is
     determined on the basis of coupon interest accrued, adjusted for accretion
     of discount or amortization of premium using the yield - to - maturity
     method on long-term debt securities and short-term securities with greater
     than sixty days to maturity. Realized gains and losses from securities sold
     are recorded on the identified cost basis. The Portfolio does not isolate
     that portion of the results of operations resulting from changes in foreign
     exchange rates on investments from the fluctuations arising from changes in
     market prices of securities held. Such fluctuations are included with the
     net realized and unrealized gain or loss from investments. Net realized
     gains and losses on foreign currency transactions represent gains and
     losses on disposition of foreign currencies and forward foreign currency
     exchange contracts, currency gains and losses realized between the trade
     and settlement dates on securities transactions, and the difference between
     the amount of investment income and foreign withholding taxes recorded on
     the Portfolio's books and the U.S. dollar equivalent amounts actually
     received or paid.

     C. INCOME TAXES

     The Portfolio is treated as a partnership for federal tax purposes. No
     provision is made by the Portfolio for federal or state income taxes on any
     taxable income of the Portfolio because each investor in the Portfolio is
     ultimately responsible for the payment of any taxes. Since at least one of
     the Portfolio's investors is a regulated investment company that invests
     all or substantially all of its assets in the Portfolio, the Portfolio
     normally must satisfy the source of income and diversification requirements
     applicable to regulated investment companies (under the Internal Revenue
     Code) in order for its investors to satisfy them. The Portfolio allocates
     at least annually among its investors each investor's distributive share of
     the Portfolio's net investment income, net realized capital gains, and any
     other items of income, gain, loss deduction or credit.

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     D. FOREIGN CURRENCY TRANSACTIONS

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

     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.

     E. INVESTMENT RISK

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

     F. COMMITMENTS AND CONTINGENCIES

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

     G. EXPENSES

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

     H. AFFILIATED ISSUERS

     Affiliated issuers represent issuers in which the Portfolio held
     investments in other investment companies advised by Standish Mellon Asset
     Management Company LLC ("Standish Mellon"), a wholly-owned subsidiary of
     Mellon Financial Corporation, or its affiliates.

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

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

     The Portfolio compensates Mellon Bank, N.A. under a custody, administration
     and accounting services agreement for providing custody, fund
     administration and fund accounting services for the Portfolio. Pursuant to
     this agreement the Portfolio paid $150,228 during the year ended December
     31, 2004.

     The Fund entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement Mellon Bank receives an agreed upon percentage
     of the net lending revenues. This compensation is a standard form of
     compensation received by securities lending agents with respect to
     non-affiliated entities. See Note 6 for further details.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Portfolio for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Portfolio Trust pays the legal
     fees for the independent counsel of the Trustees.

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


(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Portfolio Trust's registration statement.

     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 period end. Losses may arise from
     changes in the value of the underlying instruments if there is an illiquid
     secondary market for the contract or if the counterparty does not perform
     under the contract's terms.

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

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

     The Portfolio held options at December 31, 2004. See Schedule of
     Investments for further details.

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     INTEREST RATE FLOORS

     Interest rate floors purchased by the Portfolio entitle the Portfolio to
     receive payments on a notional principal amount from the party selling such
     floor to the extent that a specified index falls below a predetermined
     interest rate amount. Credit and market risk exist with respect to these
     instruments. If forecasts of interest rates and other market factors are
     incorrect, investment performance will diminish compared to what
     performance would have been if these investment techniques were not used.
     Even if the forecasts are correct, there are risks that the positions may
     correlate imperfectly with the asset or liability being hedged, a liquid
     secondary market may not always exist, or a counterparty to a transaction
     may not perform. The Portfolio expects to enter these transactions
     primarily for hedging purposes including, but not limited to, preserving a
     return or spread on a particular investment or portion of its portfolio,
     protecting against interest rate fluctuations, as a duration management
     technique or protecting against an increase in the price of securities the
     Portfolio anticipates purchasing at a later date. Interest rate floors are
     "marked-to-market" daily based on quotations from market makers and the
     change, if any, is recorded as unrealized appreciation or depreciation in
     the Statement of Operations. Periodic payments of interest, if any, are
     reported as additions to interest income in the Statement of Operations.
     Realized gains or losses from these agreements are disclosed in the
     Statement of Operations.

     The Portfolio did not enter into any interest rate floors during the year
     ended December 31, 2004.

     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.

     The Portfolio held open foreign currency exchange contracts at December 31,
     2004. See Schedule of Investments for further details.

     FUTURES CONTRACTS

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

     The Portfolio held open financial futures contracts at December 31, 2004.
     At December 31, 2004, the Portfolio had segregated sufficient cash and/or
     securities to cover margin requirements on open futures contracts. See
     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 and credit
     default 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

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     particular corporate or sovereign issuer's default. 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 from market makers and 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 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
     on 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.

     The Portfolio held open swap contracts at December 31, 2004. See 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, 2004
     resulting in $48,570 of security lending income. At December 31, 2004, the
     Portfolio had securities valued at $72,044,892 on loan. See the Statement
     of Investments for further detail on the security positions on loan.

(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.

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Portfolio as an unrealized gain or loss. If the TBA sale commitment is
     closed through the acquisition of an offsetting purchase commitment, the
     Portfolio realizes a gain or loss from the sale of the securities based
     upon the unit price established at the date the commitment was entered
     into. See Schedule of Investments for further details.

            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,
     2004, and the results of its operations, the changes in its net assets, and
     the financial highlights for each of the periods indicated, 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, 2004
     by correspondence with the custodian and brokers, provide a reasonable
     basis for our opinion.

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.

The year was largely positive for the financial markets, as the economic
expansion continued. However,  as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point  in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

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

For the year 2004, the Standish Mellon Opportunistic High Yield Bond Fund has
returned 10.85% while  the Merrill Lynch Master II High Yield Index was up
10.87% for the same period. The 10-year US Treasury yield closed the month at
4.22%, down from 4.35% at the November close and basically coming full circle
from its starting point (4.25%) at the start of the year. The Lehman Aggregate
Index gained .92% in December and finished with a 2004 return of 4.34%. On an
index comparison basis high yield has bested higher quality fixed income by over
600 basis points in 2004. With a strong fourth quarter, equities had a good year
in 2004 as the S&P 500 gained 10.74% and small cap stocks performed
significantly better than that. The other star in the fixed income asset class
was Emerging Markets, which, along with high yield closed the year with a string
of good months and recorded a 2004 return of close to 12%.

During the year the Index benchmark for the Fund was changed from the Lehman
Brothers US High Yield Index to the Merrill Lynch Master II High Yield Index.
Both indexes use similar methodology but the change was made for reasons of
market acceptance, usability and transparency to outside investors. The Lehman
High Yield Index returned 11.13% for 2004.

As the high yield rally has continued in the last four months, lower quality
names have led performance.  For December CCC-rated bonds returned a healthy
+3.09%, and as they did in November, October and September, clearly outdistanced
both the BB (+1.24%) and B (+1.16%) quality sectors. The hot performance of
CCC's in the last four months of 2004 has left the relative performance
situation in high yield an almost miniature repeat of 2003, with lower-priced,
higher-yielding bonds significantly outperforming issues from stronger credits.
For the year BB's reported a YTD result of +9.33%, B's stand at +10.44% and
CCC's finished with a remarkable return of +15.75%.

The lower quality theme favoring higher yields and lower dollar prices during
2004 was even more clearly demonstrated by the performance of the market's
distressed credits. Looking at credit quality on a ratings-blind basis shows
distressed credits (those with spreads greater than 1,000 basis points over
Treasuries) had another huge month in December at +7.44% as compared to
non-distressed names return of 1.24%. Spreads on the non-distressed cohort
widened a small bit in December from +271 to +279. With strong performance in
the fourth quarter, bonds categorized as distressed (+24.78% annual return)
outperformed their non-distressed peers (+10.23%) in 2004.

As was the case in the previous two months, outperformance by speculative,
distressed credits dominated the top industry returns in December, primarily
driven by snapbacks in some of the sectors that have struggled for most of the
year. Air Transport again topped this list as labor negotiation progress and
some relief on the fuel cost front boosted optimism and produced a monthly
return of 7.23%. Airlines remain as the only losing sector on the year at -.40%.
Telecom was another winner in December at +2.28%. No industries had negative
returns for the month. Some of the weaker December performances were turned in
by some of the market's more stable sectors including Consumer Products (.57%),
Gaming (+.75%) and the previously strong Building Materials sector (+.50%).

                                       2


Generally speaking industry returns were quite closely bunched in 2004 with
Airlines being the only industry without a positive yearly return. The Fund had
a small exposure to the airline sector through  some EETC holdings in
Continental and Northwest Airlines, two of the more liquid companies in a  tough
industry. Those holdings were actually a small positive for performance as they
were purchased at favorable prices. The snap back dynamic among sectors that
underperformed in 2003 sponsored the year's big industry winners as Textile and
Apparel (+28.08 2004 return), Steel (+19.32%) and Chemicals (+15.48%) topped the
yearly return chart. With the exception of Chemicals none of these industries
represents a large part of the high yield market.

On an issuer specific basis the largest index contributions came from three
sources: 1) recovering pipelines and utilities (El Paso, Williams and Edison
International) 2) Wireline Telecom (AT&T, Quest and MCI) and 3) large distressed
issuers (Charter, Calpine and Levi Strauss). The Fund had large exposures to the
pipeline and utility area which was helpful to performance although our holdings
were concentrated more in the regulated operating pipeline and first mortgage
utility bonds than in the holding company issues that provided the very largest
returns. Although we did have investments (where permitted by ratings
guidelines) to the wireline telecom providers our exposure was smaller than the
index and focused on the safety of operating-company and shorter-maturity bonds.
Our stance here was dictated by continued competition and the technological
threats to the business model of these companies. Lastly, Standish portfolios
are never highly exposed to distressed issuers. We did not like in 2004 and
continue not to like for 2005, the finances of Charter or Calpine. Neither
company looks like it can come close to supporting its current debt load and
both situations appear to contain large risks to the capital of bondholders
despite the two issuers ability to solve liquidity problems by accessing the
high yield market by issuing various types of secured paper.

MARKET ENVIRONMENT

In 2004 high yield investors were once more handsomely rewarded for
concentrating on the highest yielding opportunities in the market. Risk seeking
investors also had a big hand in shaping the composition of the new issues that
came to market as speculative-grade issues represented a large share of new
deals. In 2004 new global high yield issuance hit an all-time record of over
$160 billion. Almost 20% of that new issuance was rated speculative grade CCC or
lower. As a contrast in 2003 about 7% of new issuance carried speculative
ratings and, in the credit stressed environment of 2001 and 2002, the share was
around 3%. An interesting note on the demand side was the fervent search for
high yield bonds that took place despite annual outflows of over $4 billion from
high yield mutual funds. Yield-thirsty institutional investors and other
constituencies such, as hedge funds and structured credit vehicles, more than
made up for the slide in retail demand as compared to 2003 when mutual funds had
significant inflows.

                                       3


PORTFOLIO STRATEGY AND OUTLOOK

On the year high yield spreads tightened over 100 basis points as the broad ML
Master II Index spread fell from 418 bp at the close of 2003 to +310 at year-end
2004. Much of this spread tightening took place in the fourth quarter of the
year. High yield is now at a point where the market looks overpriced on the
basis of historically very low yields (the average B-rated bond yields about
6.80%) and spreads, combined with a risky overall ratings profile given the
expansion of speculative rated securities. The broad Merrill Lynch Index now has
14% of its market value in CCC and lower rated securities and the similar Lehman
index reports over 17%. This extreme valuation situation is more stable than it
appears however as a number of positive market forces derived from stable credit
conditions and an acute lack of attractive yield-oriented investment
alternatives have provided supporting technicals and comfort to investors
holding credit risk.

Over the last half of 2004 the credit risk of the Standish portfolio has been
reduced a bit and even more focus has been placed on identifying improving
credit situations. The portfolio also now holds a number of floating-rate high
yield bond issues and these should continue to provide good performance and
serve as a counterbalance to some of the longer duration investments that have
been made in improving credits where spreads are expected to tighten. As always
credit vigilance will be high and that should be the driver of portfolio returns
in 2005.

                          SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

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, 2004 to December 31, 2004).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST

                 STANDISH MELLON OPPORTUNISTIC HIGH YIELD FUND

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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 Opportunistic High Yield Bond Fund (the "Fund") is a
     separate non-diversified investment series of the Trust.

     The objective of the Fund is to maximize total return, consistent with
     preserving principal, primarily through the generation of current income
     and, to a lesser extent, capital appreciation by investing, under normal
     circumstances, at least 80% of net assets in below investment grade fixed
     income securities.

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

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     are valued at amortized cost, which approximates market value. If the Fund
     acquires a short-term instrument with more than sixty days remaining to its
     maturity, it is valued at current market value until the sixtieth day prior
     to maturity and will then be valued at amortized value based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized value 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 accrued, 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 Fund does not isolate
     that portion of the results of operations resulting from changes in foreign
     exchange rates on investments from the fluctuations arising from changes in
     market prices of securities held. Such fluctuations are included with the
     net realized and unrealized gain or loss from investments. Net realized
     gains and losses on foreign currency transactions represent gains and
     losses on disposition of foreign currencies and forward foreign currency
     exchange contracts, currency gains and losses realized between the trade
     and settlement dates on securities transactions, and the difference between
     the amount of investment income and foreign withholding taxes recorded on
     the Fund's books and the U.S. dollar equivalent amounts usually received or
     paid.

     C. FOREIGN CURRENCY TRANSACTIONS

     The Fund keeps 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 at the valuation date. 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.

     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. 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

                                       18


                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST

                 STANDISH MELLON OPPORTUNISTIC HIGH YIELD FUND

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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.

     E. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. Dividends from net investment income and
     distributions from capital gains, if any, are reinvested in additional
     shares of the Fund unless the shareholder elects to receive them in cash.
     Income and capital gain distributions are determined in accordance with
     income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in distribution reclassifications, are primarily due to
     differing treatments for losses deferred due to wash sales, foreign
     currency gains and losses, post-October losses, amortization and/or
     accretion of premiums and discounts on certain securities and the timing of
     recognition of gains and losses on futures contracts.

     Permanent book and tax basis differences will result in reclassifications
     among undistributed net investment income, accumulated net realized gain
     (loss) and paid in capital. Undistributed net investment income and
     accumulated net realized gain (loss) on investments and foreign currency
     transactions 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.

     F. EXPENSES

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

     G. COMMITMENTS AND CONTINGENCIES

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

     H. AFFILIATED ISSUERS

     Affiliated issuers represent issuers in which the Fund held investments in
     other investment companies advised by Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary Mellon Financial
     Corporation, or its affiliates.

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

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory, administrative services, and general office facilities, is paid
     monthly at the annual rate of 0.40% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit total Fund operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     0.10% of the Fund's average daily net assets for the year ended December
     31, 2004. Pursuant to this agreement, for the year ended December 31, 2004,
     Standish Mellon collectively and voluntarily waived its investment advisory
     fee in the amount of $139,739 and reimbursed the Fund for $114,412 of its
     operating expenses. This agreement is voluntary and temporary and may be
     discontinued or revised by Standish Mellon at any time.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per

     expenses. Pursuant to this agreement the Fund paid $60,759 during the year
     ended December 31, 2004.

     At December 31, 2004, three shareholders of record held approximately 48%

     of the total outstanding shares of the Fund. Investment activity of these
     shareholders could have a material impact on the Fund.

     fiduciary accounts over which Standish Mellon and its affiliates have
     either sole or joint investment discretion.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes all of its taxable income for its fiscal year.

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2004, was as follows:

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

     At December 31, 2004, the Fund, for federal income tax purposes, has
     capital loss carryovers of $16,104,478 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:

           Ordinary income        $2,893,284            $3,206,052


(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     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 securities 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 options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     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 writer of
     an option, has no control over whether the underlying securities may be
     sold (call) or purchased (put) and as a result bears the market risk of an
     unfavorable change in the price of the security underlying the written
     option.

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

     The Fund did not enter into any option transactions during the year ended
     at December 31, 2004.

     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.

     The Fund held forward currency exchange contracts at December 31, 2004. See
     Schedule of Investments for further details.

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     FUTURES CONTRACTS

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

     The Fund did not enter into any futures contracts during the year ended
     December 31, 2004.

     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 and credit default 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. 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 from market makers and 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 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 or loss. Entering into these
     agreements involves, to varying degrees, elements of credit, market, and
     documentation risk in excess of the amounts recognized on 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.

      The Fund held swap contracts at December 31, 2004. See 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, 2004
     resulting in security lending income of $5,527. At December 31, 2004, the
     Fund had securities worth $2,009,807 on loan. See Schedule of Investments
     for further detail on the security positions on loan and collateral held.

(8)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Fund as an unrealized gain or loss. If the TBA sale commitment is closed
     through the acquisition of an offsetting purchase commitment, the Fund
     realizes a gain or loss from the sale of the securities based upon the unit
     price established at the date the commitment was entered into.

     The Fund did not enter into any delayed delivery transactions during the
     year ended December 31, 2004.

(9)  CONCENTRATION OF RISK:

     The Fund invests in low rated (non-investment grade) and comparable quality
     unrated high yield securities. Investments in high yield securities are
     accompanied by a greater degree of credit risk and the value of high yield
     securities tends to be more sensitive to economic conditions than higher
     rated securities. The risk of loss due to default of an issuer may be
     significantly greater for holders of high yield securities, because such
     securities are generally unsecured and are often subordinated to other
     creditors of the issuer.

     There are certain additional considerations and risks associated with
     investing in foreign securities and currency transactions that are not
     inherent with investments of domestic origin. The Fund's investment in
     emerging market countries may involve greater risks than investments in
     more developed markets and the price of such investments may be volatile.
     These risks of investing in foreign and emerging markets may include
     foreign currency exchange rate fluctuations, perceived credit risk, adverse
     political and economic developments and possible adverse foreign government
     intervention.

(10) LINE OF CREDIT:

     The Fund, and other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio Trust (the "Portfolio 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 .060 of 1% committed amount,
     is allocated ratably among the participating portfolios/funds at the end of
     each quarter. For the year ended December 31, 2004, a facility fee of $420
     was allocated to the Fund.

     During the year ended December 31, 2004, the Fund did not borrow under the
     credit facility.

     and the financial highlights for each of the periods indicated, in
     conformity with accounting principles generally accepted in the United
     States of America. These financial statements and financial highlights

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.

The year was largely positive for the financial markets, as the economic
expansion continued. However,  as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point  in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its' 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

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 Emerging Market debt asset class performed well in 2004, due both to a
supportive environment for risky assets and to fundamental improvements in the
economic condition of many emerging market countries. Volatility in the Treasury
market did spill over into Emerging Market debt, particularly during the
April-May sell-off. The year 2004 was the third full year for the Opportunistic
Emerging Market Fund and it returned 11.54%, barely behind the J.P. Morgan EMBI
Global benchmark (11.74% return). Uruguay was the best performing market with a
return of 34%; the country continued recovering strongly from its collapse in
2002 and benefited from early constructive signals sent by the incoming Vasquez
administration. Other notable performers included Dominican Republic, Venezuela,
and Ecuador, all with returns above 20%, the later two helped by strong oil
prices and reduced political uncertainty. The worst performing market in the
high-beta universe was Ukraine; it managed a 7.2% return in 2004, as political
noise was a constant throughout the year. Other key markets such as Mexico and
Russia returned 8.6% and 11.5%, respectively. Argentina's bond prices also
performed strongly, returning 19.8%, as its long-delayed exchange draws nearer.

Emerging market debt was driven by three important factors for most of 2004: the
US economic outlook, continued improvements in Emerging Market countries'
fundamentals, and new inflows into the asset class.

Early in the year, strong inflows into the asset class kept the momentum from
2003 going, but long-duration supply and political scandals in EM bellwether
Brazil put some pressure on spreads, which range-traded during most of the first
four months of the year. However, due to stronger than expected payroll reports,
Treasuries sold off by over 100 bps during April and May. This negatively
affected emerging market spreads as investors remembered the fallout from the
1994 Mexico crisis that was in part caused by a rise in Treasury yields.
Throughout this period, EM spreads widened by more than 100 basis points.

EM spreads remained volatile until late May, when tame inflation and weak
employment growth led the market to believe that a dramatic tightening by the
Fed was not to occur. Since then, EM spreads have been on a clear downward path.
Once US Treasury rates stabilized, emerging market spreads continued to
contract, falling by 200 basis points by yearend. Throughout the year, but
especially in the second half, new inflows into the asset class from
institutional and retail investors helped keep bond prices well supported.
Moreover, most of the positive rating actions in EM universe materialized
throughout the second half of the year, supporting higher bond valuations.

In late June the Federal Reserve began its long awaited tightening process,
raising its benchmark rate by 25 basis points. In total, the Fed tightened rates
by 125 basis points in 2004. Its' "measured" pace of tightening has provided
support to fixed income markets.

In terms of performance, the Fund had two distinct phases. During the first half
of the year, performance was disappointing, as risk in high-beta credits and
interest rate duration were not cut enough during the April-May selloff.
However, the underperformance was almost made up during the second half, as the
Fund correctly overweighted high-beta assets in Brazil, Ecuador, Argentina
(Boden 12), Russia (Aries bonds) and Turkey.

                                       2


In 2005 we expect the first half of the year to be somewhat of a continuation of
the trends in 2004 with the Federal Reserve continuing its policy
"normalization" and continued credit improvement in many emerging markets.
During the second half of the year the outlook is less certain as, depending on
incoming data on inflation and growth, the Federal Reserve might change its
"measured" pace of tightening and all fixed income assets, including emerging
market debt, might overshoot in either direction. Other factors such as a
disorderly decline in the value of the US dollar, another terrorist strike or
investor uneasiness with upcoming elections in several countries during 2006
could pose challenges during the course of the year.

We thank you for your continued support.

                          SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

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, 2004 to December 31, 2004).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST

           STANDISH MELLON OPPORTUNISTIC EMERGING MARKETS DEBT FUND

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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 Opportunistic Emerging Markets Debt Fund (the "Fund") is a
     separate non-diversified investment series of the Trust.

     The objective of the Fund is to generate a high total return through a
     combination of capital appreciation and income. The fund seeks to achieve
     its objective by investing, under normal circumstances, at least 80% of net
     assets in fixed income securities issued by governments, companies and
     banks of emerging markets, as well as preferred stocks, warrants and
     tax-exempt bonds.

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

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     are valued at amortized cost, which approximates market value. If the Fund
     acquires a short-term instrument with more than sixty days remaining to its
     maturity, it is valued at current market value until the sixtieth day prior
     to maturity and will then be valued at amortized value based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized value 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 accrued, 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 Fund does not isolate
     that portion of the results of operations resulting from changes in foreign
     exchange rates on investments from the fluctuations arising from changes in
     market prices of securities held. Such fluctuations are included with the
     net realized and unrealized gain or loss from investments. Net realized
     gains and losses on foreign currency transactions represent gains and
     losses on disposition of foreign currencies and forward foreign currency
     exchange contracts, currency gains and losses realized between the trade
     and settlement dates on securities transactions, and the difference between
     the amount of investment income and foreign withholding taxes recorded on
     the Fund's books and the U.S. dollar equivalent amounts usually received or
     paid.

     C. FOREIGN CURRENCY TRANSACTIONS

     Investment security valuations, other assets, and liabilities initially
     expressed in foreign currencies are converted into U.S. dollars based upon
     current currency exchange rates at the valuation date. 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.

     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. 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

                                       15

                  MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST

           STANDISH MELLON OPPORTUNISTIC EMERGING MARKETS DEBT FUND

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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.

     E. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. Dividends from net investment income and
     distributions from capital gains, if any, are reinvested in additional
     shares of the Fund unless the shareholder elects to receive them in cash.
     Income and capital gain distributions are determined in accordance with
     income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in distribution reclassifications, are primarily due to
     differing treatments for losses deferred due to wash sales, foreign
     currency gains and losses, post-October losses, amortization and/or
     accretion of premiums and discounts on certain securities and the timing of
     recognition of gains and losses on futures contracts.

     Permanent book and tax basis differences will result in reclassifications
     among undistributed net investment income, accumulated net realized gain
     (loss) and paid in capital. Undistributed net investment income and
     accumulated net realized gain (loss) on investments and foreign currency
     transactions 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.

     F. EXPENSES

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

     G. COMMITMENTS AND CONTINGENCIES

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

     H. AFFILIATED ISSUERS

     Affiliated issuers represent issuers the Fund held in other investment
     companies advised by Standish Mellon Asset Management Company LLC
     ("Standish Mellon"), a wholly-owned subsidiary Mellon Financial
     Corporation, or its affiliates.

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

     The investment advisory fee paid to Standish Mellon overall investment
     advisory, administrative services, and general office facilities, is paid
     monthly at the annual rate of 0.50% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit total Fund operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     0.30% of the Fund's average daily net assets for the year ended December
     31, 2004. Pursuant to this agreement, for the year ended December 31, 2004,
     Standish Mellon voluntarily waived its investment advisory fee in the
     amount of $76,578 and reimbursed the Fund for $65,117 of other operating
     expenses. This agreement is voluntary and temporary and may be discontinued
     or revised by Standish Mellon at any time.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per
     account and transaction based fees, as well as, out-of-pocket expenses.
     Pursuant to this agreement the Fund paid $2,655 during the period ended
     December 31, 2004.

     The Fund has contracted Mellon Bank, N.A. ("Mellon Bank"), a wholly owned
     subsidiary of Mellon Financial Corporation and an affiliate of Standish
     Mellon, to provide custody, fund administration and 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 paid $41,014 during the year
     ended December 31, 2004.

     The Fund entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement Mellon Bank receives an agreed upon percentage
     of the net lending revenues. This compensation is a standard form of
     compensation received by securities lending agents with respect to
     non-affiliated entities. See Note 7 for further details.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

     At December 31, 2004, five shareholders of record held approximately 79% of
     the total outstanding shares of the Fund. Investment activity of these
     shareholders could have a material impact on the Fund.

     A significant portion of the Fund's shares represent investments by
     fiduciary accounts over which Standish Mellon and its affiliates have
     either sole or joint investment discretion.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes all of its taxable income for its fiscal year.

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2004, was as follows:


                                                               AMOUNT

                         NOTES TO FINANCIAL STATEMENTS

(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     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 securities 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 options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     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 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

     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.

           STANDISH MELLON OPPORTUNISTIC EMERGING MARKETS DEBT FUND

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     The Fund held these contracts at December 31, 2004. See Schedule of
     Investments for further details.

     FUTURES CONTRACTS

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

     The Fund held these contracts at December 31, 2004. See 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 and credit default 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. 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 from market makers and 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 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 or loss. Entering into these
     agreements involves, to varying degrees, elements of credit, market, and
     documentation risk in excess of the amounts recognized on 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.

     The Fund held swap contracts at December 31, 2004. See 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, 2004
     resulting in security lending income of $6,591. At December 31, 2004, the
     Fund had securities valued at $371,647 on loan. See Schedule of Investments
     for further detail on the security positions on loan and collateral held.

(8)  DELAYED DELIVERY TRANSACTIONS:

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

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

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

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Fund as an unrealized gain or loss. If the TBA sale commitment is closed
     through the acquisition of an offsetting purchase commitment, the Fund
     realizes a gain or loss from the sale of the securities based upon the unit
     price established at the date the commitment was entered into.

     The Fund held delayed delivery securities during the year ended December
     31, 2004. See Schedule of Investments for further details.

(8)  LINE OF CREDIT:

     The Fund, and other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio Trust (the "Portfolio 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 .060 of 1% committed amount,
     is allocated ratably among the participating portfolios/funds at the end of
     each quarter. For the year ended December 31, 2004, a facility fee of $140
     was allocated to the Fund.

     During the year ended December 31, 2004, the Fund had average borrowings
     outstanding of $45,400 on a total of fifteen days and incurred $50 of
     interest expense.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon Opportunistic Emerging Markets Debt 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 Opportunistic Emerging Markets Debt Fund (the "Fund") at
     December 31, 2004, and the results of its operations, the changes in its
     net assets, and the financial highlights for each of the periods indicated,
     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, 2004 by correspondence
     with the custodian and brokers, provide a reasonable basis for our opinion

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.
The year was largely positive for the financial markets, as the economic
expansion continued. However,  as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point  in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

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

Sincerely,

Patrick J. Sheppard

                      MANAGEMENT DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

Economic activity maintained a healthy pace in 2004. The employment picture
improved with monthly job gains averaging approximately 185,000. Investment
spending and capacity utilization picked up, and  despite higher interest rates,
the housing market and consumer spending kept pace. For the year ending December
31, 2004, the Standish Mellon Investment Grade Bond Fund returned 4.53% while
the Lehman Brothers Aggregate Index returned 4.34% for the same period. Amid
rising oil prices and a weaker dollar, the Federal Reserve maintained a tame
inflation outlook. Bond market volatility was low as the Fed hiked interest
rates in a predictable and steady fashion from 1% to 2.25% by the end of the
year. The unusual aspect of this tightening cycle has been the decline in 10-
and 30-year yields as short rates have risen. So while the yield curve has
flattened similarly to previous cycles, long-term interest rates have moved to
lower levels than expected. To a large degree, the massive foreign purchases of
U.S. Treasuries have kept long-term interest rates lower than anticipated during
a period of tighter monetary policy.

Over the past year, broad sectors outperformed Treasuries with particularly
strong excess returns from investment grade corporate bonds. Spread sectors,
especially mortgages, benefited from declining interest rate volatility. The
credit sector fared well amid steady economic activity. Treasury
inflation-protected securities (TIPS) outperformed nominal Treasuries as both
actual and expected levels of inflation rose. Over the course of the year, the
primary sources of outperformance were the overweight positions in corporate
bonds and TIPS, as well as the defensive yield curve strategy. As the curve
flattened, the Fund's underweight position in intermediate bonds (bullet
strategy) relative to cash and longer maturities (barbell strategy) benefited
returns. Portfolio positioning also capitalized on the lower volatility
environment with an increased allocation to mortgages. Toward year-end, with
much narrower corporate bond spreads, we selectively reduced the Fund's
investment grade credit exposure.

We believe prospects for economic growth in 2005 are good. We expect reasonably
strong economic data will support continued rate hikes by the Fed. Under tighter
monetary conditions, we anticipate upward pressure on interest rates and a
flatter yield curve. With today's low volatility environment and narrow yield
spreads, many sectors appear overvalued. Given the vulnerability to a correction
in spread sectors, we have positioned the Fund defensively, particularly with a
reduced corporate bond position. We have increased our allocation to Treasury
inflation-protected securities as seasonal inflation patterns and breakeven
inflation rates in the area of 2.5% make TIPS attractive relative to nominal
Treasuries. Ultimately, if as we expect,  the Fed maintains their tightening
stance, the Fund's shorter than benchmark duration and barbell curve position
will continue to contribute positively to performance.

As always, we look forward to serving you in the coming year.

                          SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

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, 2004 to December 31, 2004).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

(a)  The Fund has adopted the provisions of the revised AICPA Audit and
Accounting Guide for Investment Companies effective January 1, 2001 and began
amortizing premium and discount on all debt securities on an effective yield
basis. The effect of this change for the year ended December 31, 2001 was to
decrease net investment income per share by $0.004, increase net realized and
unrealized gains and losses per share by $0.004 and decrease the ratio of net
investment income to average net assets from 6.02% to 6.00%. Per share data and
ratios/supplemental data for the periods prior to January 1, 2001 have not been
restated to reflect this change in presentation.

 MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST STANDISH MELLON INVESTMENT GRADE
                                   BOND FUND

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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 Investment Grade Bond Fund (the "Fund") is a separate
     diversified investment series of the Trust.

     The objective of the Fund is to maximize total return, consistent with
     preserving principal and liquidity, primarily through the generation of
     current income and, to a lesser extent, capital appreciation. The Fund
     seeks to achieve its objective by investing, under normal circumstances, at
     least 80% of net assets in investment grade fixed income securities
     including, but not limited to, government, agency, corporate and mortgage
     and asset-backed issues.

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

     A. INVESTMENT SECURITY VALUATIONS

     Securities for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     are valued at amortized cost, which approximates market value. If the Fund
     acquires a short-term instrument with more than sixty days remaining to its
     maturity, it is valued at current market value until the sixtieth day prior
     to maturity and will then be valued at amortized value based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized value 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 accrued, 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

     C. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income and distributions from capital gains,
     if any, are reinvested in additional shares of the Fund unless the
     shareholder elects to receive them in cash. Income and capital gain
     distributions are determined in accordance with income tax regulations
     which may differ from generally accepted accounting principles. These
     differences, which may result in distribution reclassifications, are
     primarily due to differing treatments for losses deferred due to wash
     sales, amortization and/or accretion of premiums and discounts on certain
     securities and the timing of recognition of gains and losses on futures
     contracts.

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

     D. EXPENSES

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

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

     E. COMMITMENTS AND CONTINGENCIES

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

     F. AFFILIATED ISSUERS

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

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

     The investment advisory fee paid to Standish Mellon for overall investment
     advisory, administrative services, and general office facilities, is paid
     monthly at the annual rate of 0.40% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit total Fund operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     0.40% of the Fund's average daily net assets for the year ended December
     31, 2004. Pursuant to this agreement, for the year ended December 31, 2004,
     Standish Mellon collectively and voluntarily waived a portion of its
     investment advisory fee in the amount of $210,523. This agreement is
     voluntary and temporary and may be discontinued or revised by Standish
     Mellon at any time.

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per
     account and transaction based fees, as well as, out-of-pocket expenses.
     Pursuant to this agreement the Fund paid $4,269 during the period ended
     December 31, 2004.

     The Fund has contracted Mellon Bank, N.A. ("Mellon Bank"), a wholly owned
     subsidiary of Mellon Financial Corporation and an affiliate of Standish
     Mellon, to provide custody, fund administration and 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 paid $80,875 during the year
     ended December 31, 2004.

     The Fund entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement Mellon Bank receives an agreed upon percentage
     of the net lending revenues. This compensation is a standard form of
     compensation received by securities lending agents with respect to
     non-affiliated entities. See Note 7 for further details.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon or its affiliates an
     annual fee and a per meeting fee as well as reimbursement for travel and
     out of pocket expenses. In addition, the Trust pays the legal fees for the
     independent counsel of the Trustees.

(3)  PURCHASES AND SALES OF INVESTMENTS:

     Purchases and proceeds from sales of investments, excluding short-term
     securities, for the year ended December 31, 2004 were as follows:

     At December 31, 2004, three shareholders of record held approximately 90%
     of the total outstanding shares of the Fund. Investment activity of these
     shareholders could have a material impact on the Fund.

     A significant portion of the Fund's shares represent investments by
     fiduciary accounts over which Standish Mellon and its affiliates have
     either sole or joint investment discretion.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes all of its taxable income for its fiscal year.

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2004, was as follows:

(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     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 securities 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 options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     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 writer of
     an option, has no control over whether the underlying securities may be
     sold (call) or purchased (put) and as a result bears the market risk of an
     unfavorable change in the price of the security underlying the written
     option.

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

     The Fund entered into option transactions at December 31, 2004. See
     Schedule of Investments for further details

     INTEREST RATE FLOORS

     Interest rate floors purchased by the Fund entitle the Fund to receive
     payments on a notional principal amount from the party selling such floor
     to the extent that a specified index falls below a predetermined interest
     rate amount. Credit and market risk exist with respect to these
     instruments. If forecasts of interest rates and other market factors are
     incorrect, investment performance will diminish compared to what
     performance would have been if these investment techniques were not used.
     Even if the forecasts are correct, there are risks that the positions may
     correlate imperfectly with the asset or liability being hedged, a liquid
     secondary market may not always exist, or counterparty to a transaction may
     not perform. The Fund expects to enter these transactions primarily for
     hedging purposes including, but not limited to, preserving a return or
     spread on a particular investment or portion of its portfolio, protecting
     against interest rate fluctuations, as a duration management technique or
     protecting against an increase in the price of securities the Fund
     anticipates purchasing at a later date. Interest rate floors are
     marked-to-market daily based on quotations from market makers and the
     change, if any, is recorded as unrealized appreciation or depreciation in
     the Statement of Operations. Realized gains or losses from these agreements
     are disclosed in the Statement of Operations.

     The Fund did not enter into any interest rate floor transactions during the
     year ended December 31, 2004.

     FUTURES CONTRACTS

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

     The Fund held futures at December 31, 2004. At December 31, 2004 the Fund
     had segregated cash and /or securities to cover margin requirements on open
     future contracts. See Schedule of Investments for further details.

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     SWAP AGREEMENTS

     The Fund may invest in 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 and credit default 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. 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 from market makers and 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 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
     are included as part of realized gain loss. Entering into these agreements,
     if any, involves, to varying degrees, elements of credit, market, and
     documentation risk in excess of the amounts recognized on 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.

     The Fund entered into swap agreements at December 31, 2004. See 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, 2004
     resulting in security lending income of $5,738. At December 31, 2004, the
     Fund had securities valued at $2,750,554 on loan. See Schedule of
     Investments for further detail on the security positions on loan and
     collateral held.

(8)  DELAYED DELIVERY TRANSACTIONS:

     The Fund may purchase or sell securities on a when-issued, delayed delivery
     or forward commitment basis. This Fund segregates securities having a value
     at least equal to the amount of the purchase commitment.

     The Fund may enter into to be announced ("TBA") purchase commitments to
     purchase securities for a fixed unit price at a future date beyond
     customary settlement time. Although the unit price has been established,
     the principal value has not been finalized. However, the amount of the
     commitments will not fluctuate more than 0.01% from the principal amount.
     The Fund holds, and maintains until settlement date, cash or high-grade
     debt obligations in an amount sufficient to meet the purchase price, or the
     Fund may enter into offsetting contracts for the forward sale of other
     securities it owns. Income on the securities will not be earned until
     settlement date. TBA purchase commitments may be considered securities in

     themselves, and involve a risk of loss if the value of the security to be
     purchased declines prior to the settlement date, which risk is in addition
     to the risk of the decline in the value of the Fund's other assets.
     Unsettled TBA purchase commitments are valued at the current market value
     of the underlying securities, according to the procedures described under
     "Investment security valuations" above.

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

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Fund as an unrealized gain or loss. If the TBA sale commitment is closed
     through the acquisition of an offsetting purchase commitment, the Fund
     realizes a gain or loss from the sale of the securities based upon the unit
     price established at the date the commitment was entered into.

     See the Schedule of Investments for outstanding delayed delivery contracts

(9)  LINE OF CREDIT:

     The Fund, and other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio Trust (the "Portfolio 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 .060 of 1% committed amount,
     is allocated ratably among the participating portfolios/funds at the end of
     each quarter. For the year ended December 31, 2004, a facility fee of $623
     was allocated to the Fund.

     During the year ended December 31, 2004, the Fund had average borrowings
     outstanding of $387,881 on a total of four days and incurred $102 of
     interest expense.

     To the Trustees of Mellon Institutional Funds Investment Trust and the
     Shareholders of Standish Mellon Investment Grade Bond 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 Investment Grade Bond Fund (the "Fund") at December 31,
     2004, and the results of its operations, the changes in its net assets, and
     the financial highlights for each of the periods indicated, 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, 2004 by correspondence
     with the custodian and brokers, provide a reasonable basis for our opinion

Dear Mellon Institutional Fund Shareholder:

Enclosed you will find your Fund's annual report for the fiscal year ended
December 31, 2004.

The year was largely positive for the financial markets, as the economic
expansion continued. However,  as the year progressed, anticipated GDP growth
diminished in line with typical expectations at this point  in the economic
cycle.

The S&P 500 entered 2004 with a sharp climb, fueled to a large degree by
above-trend GDP growth: 4.4% in the fourth quarter of 2003 and 5.0% in the first
quarter of the year, driven by a potent mix of tax cuts, monetary policy and
government spending. But the momentum stalled, as the market dealt with the
prospect of inflation and a new tightening cycle by the Federal Reserve, the
uncertainties of a tight presidential campaign, and the ever-present threats
posed by terrorism. The equity markets greeted the reelection of President Bush
with optimism, as the S&P 500 surged past 1200 in the closing weeks of the year
to its' 2004 peak.

In the bond market, the year started with much speculation about when and how
the Fed would end one of the longest stretches of easy monetary policy on
record, which had driven rates to historical lows. In the fall of 2003, the
prospect of deflation was still a factor in the Fed's deliberations and was its
stated rationale for maintaining an accommodative stance. In the first quarter,
however, the Fed began to refer to a "measured pace" of tightening. The market
reacted by switching gears dramatically, sending the 10-year U.S. Treasury note
from 3.7% on March 16 to 4.9% on June 14. Since then, as the economic outlook
softened, with relatively tame inflation, yields have settled back to about 4%,
roughly the same as a year ago.

Looking ahead, it is clear that there are some causes for concern. Consumers are
weighted with debt and potentially vulnerable in a rising rate environment.
Companies are hoarding cash and are being deliberate in boosting employment and
spending on plant and equipment. The stimulus of monetary policy, tax cuts and
government spending is waning. Nevertheless, business activity has some
significant momentum, which should carry over into 2005, with reasonable profit
growth and modest inflation. Finally, the president's ambitious plans to
privatize Social Security, reform health care, and revise the tax code could
potentially have major fiscal implications that the market will be watching
carefully.

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

International bond markets produced double-digit returns in 2004 from a
combination of positive local market returns and currency gains related to the
decline of the U.S. dollar. The Standish Mellon International Fixed Income Fund
II returned 10.73% for the year, after all expenses, compared to a return of
12.04% for the J.P. Morgan Non-U.S. Government Bond Index.

A return of more than 10% for international bonds is perhaps surprising
considering that at the beginning of the year, the consensus expectation was
that bond yields would rise as central banks raised interest rates. Indeed, bond
yields did rise early in the year and this rise was lead by the U.S. bond
market, which experienced a vicious sell-off in the first half. However, as the
year progressed, it became apparent that core inflation was well contained in
the U.S., the job market strengthened but not as much as anticipated, and growth
in large economies overseas was anemic. Bond yields in the U.S. and overseas
fell during the second half of the year, and in the end, despite the volatility,
bond investors managed to earn a bit more than their coupon. The positive return
from international bond markets combined with the gains related to the decline
of the US. Dollar, resulted in another year of strong returns from the asset
class.

The non-government sectors of the international bond markets were a pleasant
surprise producing returns well above government bonds for the second year in a
row. The star performers were corporate bonds, particularly the high-yield
sector, and emerging markets. A number of factors contributed to the
outperformance of the corporate and emerging sectors particularly global growth,
low inflation, low interest rates and in the case of the commodity laden
emerging markets, high commodity prices. The high yield corporate and emerging
market indices both had returns of over 10% for the year. Other non-government
sectors also performed well including mortgages, agencies and asset-backed
securities.

The range of returns in hedged terms for government bond markets as measured by
the JP Morgan Government Bond Indices was modest for the year with only 534
basis points, separating the best market Italy (+8.00%) from the worst, Japan
(+2.66%). The U.S. component of the index returned 3.75% while European markets
returned 6.77% on average. The U.S. dollar had traded in a modest range for most
of the year however it fell sharply in the final quarter. The decline of the
dollar was the sharpest relative to the European currencies against which it
declined by more than 7%. The U.S. dollar has been under pressure since 2002 as
the mix of loose fiscal and monetary policy and the large current account
deficit made the currency unattractive to global investors.

The Fund underperformed its benchmark during the year. Our position in
investment grade and high yield corporate bonds and emerging market securities
was the largest positive contributor relative to our benchmark. The results of
our country weightings were mixed. We were overweight European markets, which
produced the best returns however we had a zero weight in the Japanese bond
market which weighed on our performance. Although Japan was the worst performing
market in the index, our zero weighting in the market was a drag on performance
as Japan did produce a positive return. In currencies, our small primarily,
option-based positions detracted a modest amount from our performance.

                                       2


Our outlook for 2005 is favorable for international bonds. We believe that the
performance of global economies will be close to trend, yet the behavior of
central banks around the world could be quite different. The Fed will continue
to raise interest rates at least in the first half of the year and this will
flatten the yield curve but we expect longer dated bonds to be fairly stable.
Opportunities for value-added can be found in Europe and in some of the smaller
index components such as Australia, New Zealand and the U.K. In the latter three
markets, the central banks have been raising interest rates for some time and
those increases now appear to be having an effect. These economies have housing
markets that are vulnerable to price declines and if the economies soften, we
believe bonds in these markets will perform well. Non-government sectors such as
corporate and emerging market bonds have richened quite a bit over the past two
years and  we believe that these sectors will not perform as well as in the past
but that the sector still offers opportunities to add-value through security
selection.

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

                          SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------

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, 2004 to December 31, 2004).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

(a)  The Fund has adopted the provisions of the revised AICPA Audit and
Accounting Guide for Investment Companies effective January 1, 2001 and began
amortizing premium and discount on all debt securities on an effective yield
basis. The effect of this change for the year ended December 31, 2001 was to
decrease net investment income per share by $0.002, increase net realized and
unrealized gains and losses per share by $0.002 and decrease the ratio of net
investment income to average net assets from 4.00% to 3.99%. Per share data and
ratios/supplemental data for the periods prior to January 1, 2001 have not been
restated to reflect this change in presentation.

MELLON INSTITUTIONAL FUNDS INVESTMENT TRUST STANDISH MELLON INTERNATIONAL FIXED
                                INCOME FUND II

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1)  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 government 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 for which quotations are readily available are valued at the
     last sale price, or if no sale price, at the closing bid price in the
     principal market in which such securities are primarily traded. Market
     quotations are not considered to be readily available for certain debt
     obligations; such investments are stated at fair value on the basis of
     valuations furnished by a pricing service or dealers, approved by the
     Trustees, which determine valuations for normal institutional-size trading
     units of such securities using methods based on market transactions for
     comparable securities and variable relationships between securities that
     are generally recognized by institutional traders. Securities (including
     illiquid securities) for which quotations are not readily available are
     valued at their fair value as determined in good faith under consistently
     applied procedures under the general supervision of the Trustees.

     Short-term instruments with less than sixty-one days remaining to maturity
     are valued at amortized cost, which approximates market value. If the Fund
     acquires a short-term instrument with more than sixty days remaining to its
     maturity, it is valued at current market value until the sixtieth day prior
     to maturity and will then be valued at amortized value based upon the value
     on such date unless the Trustees determine during such sixty-day period
     that amortized value 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 accrued, 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 Fund does not isolate
     that portion of the results of operations resulting from changes in foreign
     exchange rates on investments from the fluctuations arising from changes in
     market prices of securities held. Such fluctuations are included with the
     net realized and unrealized gain or loss from investments. Net realized
     gains and losses on foreign currency transactions represent gains and
     losses on disposition of foreign currencies and forward foreign currency
     exchange contracts, currency gains and losses realized between the trade
     and settlement dates on securities transactions, and the difference between
     the amount of investment income and foreign withholding taxes recorded on
     the Fund's books and the U.S. dollar equivalent amounts actually received
     or paid.

     C. FOREIGN CURRENCY TRANSACTIONS

     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.

     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. 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.

     E. DISTRIBUTIONS TO SHAREHOLDERS

     Distributions to shareholders are recorded on the ex-dividend date.
     Dividends from net investment income will be declared and distributed
     quarterly. The Fund's dividends from short-term and long-term capital
     gains, if any, after reduction of capital losses will be declared and
     distributed at least annually. Dividends from net investment income and
     distributions from capital gains, if any, are reinvested in additional
     shares of the Fund unless the shareholder elects to receive them in cash.
     Income and capital gain distributions are determined in accordance with
     income tax regulations which may differ from accounting principles
     generally accepted in the United States of America. These differences,
     which may result in distribution reclassifications, are primarily due to
     differing treatments for losses deferred due to wash sales, foreign
     currency gains and losses, post-October losses, amortization and/or
     accretion of premiums and discounts on certain securities and the timing of
     recognition of gains and losses on futures contracts.

     Permanent book and tax basis differences will result in reclassifications
     among undistributed net investment income, accumulated net realized gain
     (loss) and paid in capital. Undistributed net investment income and
     accumulated net realized gain (loss) on investments and foreign currency
     transactions 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.

     F. EXPENSES

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

     G. COMMITMENTS AND CONTINGENCIES

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

     H. AFFILIATED ISSUERS

     Affiliated issuers represent issuers in which the Fund held investments in
     other investment companies advised by Standish Mellon Asset Management
     Company LLC ("Standish Mellon"), a wholly-owned subsidiary Mellon Financial
     Corporation, or its affiliates.

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

     The investment advisory fee paid to Standish Mellon overall investment
     advisory, administrative services, and general office facilities, is paid
     monthly at the annual rate of 0.40% of the Fund's average daily net assets.
     Standish Mellon voluntarily agreed to limit total Fund operating expenses
     (excluding brokerage commissions, taxes and extraordinary expenses) to
     0.75% effective January 1, 2004, from 0.55% prior to that date, of the
     Fund's average daily net assets for the year ended December 31, 2004.
     Pursuant to this agreement, for the year ended December 31, 2004, Standish
     Mellon voluntarily waived a portion of its investment advisory fee in the
     amount of $57,150 This agreement is voluntary and temporary and may be
     discontinued or revised by Standish Mellon at any time.

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     Effective February 23, 2004, the Fund entered into an agreement with
     Dreyfus Transfer, Inc., a wholly owned subsidiary of The Dreyfus
     Corporation, a wholly owned subsidiary of Mellon Financial Corporation and
     an affiliate of Standish Mellon, to provide personnel and facilities to
     perform transfer agency and certain shareholder services for the Fund. For
     these services the Fund pays Dreyfus Transfer, Inc. a fixed fee plus per
     account and transaction based fees, as well as, out-of-pocket expenses.
     Pursuant to this agreement the Fund paid $3,233 during the year ended
     December 31, 2004.

     The Fund has contracted Mellon Bank, N.A. ("Mellon Bank"), a wholly owned
     subsidiary of Mellon Financial Corporation and an affiliate of Standish
     Mellon, to provide custody, fund administration and 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 paid $75,946 during the year
     ended December 31, 2004.

     The Fund entered into an agreement with Mellon Bank to perform certain
     securities lending activities and to act as the Fund's lending agent.
     Pursuant to this agreement Mellon Bank receives an agreed upon percentage
     of the net lending revenues. This compensation is a standard form of
     compensation received by securities lending agents with respect to
     non-affiliated entities. See Note 7 for further details.

     No director, officer or employee of Standish Mellon or its affiliates
     receives any compensation from the Trust or the Fund for serving as an
     officer or Trustee of the Trust. The Trust pays each Trustee who is not a
     director, officer or employee of Standish Mellon.

     At December 31, 2004, two shareholders of record held approximately 83% of
     the total outstanding shares of the Fund. Investment activity of these
     shareholders could have a material impact on the Fund.

     A significant portion of the Fund's shares represent investments by
     fiduciary accounts over which Standish Mellon and its affiliates have
     either sole or joint investment discretion.

     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
     90 days from the day of their purchase. The redemption fee is paid directly
     to the Fund, and is designed to offset brokerage commissions, market
     impact, and other costs associated with short-term trading in the Fund. The
     fee does not apply to shares that are acquired through reinvestment of
     distributions. For the year ended December 31, 2004, the Fund did not
     collect any redemption fees.

(5)  FEDERAL TAXES:

     As a regulated investment company qualified under Subchapter M of the
     Internal Revenue Code, the Fund is not subject to income taxes to the
     extent that it distributes all of its taxable income for its fiscal year.

     The tax basis components of distributable earnings and the federal tax cost
     as of December 31, 2004, was as follows:


                                                              2004

                  Unrealized appreciation                 $  3,863,312
                  Unrealized depreciation                      (15,006)
                                                           ___________

                  Capital loss carry over                      283,844
                  Cost for federal income tax purposes     $44,182,540


     At December 31, 2004, 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

                 $283,844                  12/31/2010


     Tax character of distributions paid during the fiscal years ended December
     31, 2004, and December 31, 2003 were as follows:



                                    2004                  2003

           Ordinary income      $  1,965,761          $  3,060,410


(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
     nature, risks and objectives of these instruments are set forth more fully
     in the Fund's Prospectus and Statement of Additional Information.

     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 securities 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 options is shown in the Schedule of Investments. This amount
     reflects each contract's exposure to the underlying instrument at period
     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 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.

     December 31, 2004. The option transactions were as follows:

     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.

     The Fund held foreign currency exchange contracts at December 31, 2004. See
     Schedule of Investments for further details.

     FUTURES CONTRACTS

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

     The Fund held futures at December 31, 2004. See Schedule of Investments for
     further details.

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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 and credit default 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. 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 from market makers and 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 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 or loss. Entering into these
     agreements involves, to varying degrees, elements of credit, market, and
     documentation risk in excess of the amounts recognized on 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, 2004 the Fund held swap contracts. See 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, 2004
     resulting in security lending income of $1,209. At December 31, 2004, the
     Fund had securities valued at $956,684 on loan. See Schedule of Investments
     for further detail on the security positions on loan and collateral held.

(8)  DELAYED DELIVERY TRANSACTIONS:

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

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

                         NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

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

     Unsettled TBA sale commitments are valued at the current market value of
     the underlying securities, generally according to the procedures described
     under "Investment security valuations" above. The contract is
     'marked-to-market' daily and the change in market value is recorded by the
     Fund as an unrealized gain or loss. If the TBA sale commitment is closed
     through the acquisition of an offsetting purchase commitment, the Fund
     realizes a gain or loss from the sale of the securities based upon the unit
     price established at the date the commitment was entered into.

     The Fund did not hold any delayed delivery securities at December 31, 2004

(8)  LINE OF CREDIT:

     The Fund, and other funds in the Trust and subtrusts in the Mellon
     Institutional Funds Master Portfolio Trust (the "Portfolio 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 .060 of 1% committed amount,
     is allocated ratably among the participating portfolios/funds at the end of
     each quarter. For the year ended December 31, 2004, a facility fee of $387
     was allocated to the Fund.

     During the year ended December 31, 2004, the Fund had average borrowings
     outstanding of $26,063 on a total of four days and incurred  $4 of interest
     expense.

     31, 2004, and the results of its operations, the changes in its net assets,
     and the financial highlights for each of the periods indicated, 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, 2004 by correspondence
     with the custodian and brokers, provide a reasonable basis for our opinion

         As of December 31, 2004, the Registrant has adopted a Code of Ethics,
         as defined in Item 2(b) of Form N-CSR, that applies to the Principal
         Executive Officer and Principal Financial Officer. For the fiscal year
         ended December 31, 2004, there were no amendments to a provision of the
         Code of Ethics nor were there any waivers granted from a provision of
         the Code of Ethics. A copy of the Registrant's Code of Ethics that
         applies to the Principal Executive Officer and Principal Financial
         Officer is filed as an exhibit to this Form N-CSR under Item 11(a)(1).

ITEM 3.  AUDIT COMMITTEE FINANCIAL EXPERT.

         The Registrant's Board of Trustees has determined that the Registrant
         has more than one audit committee financial expert, as defined in Item
         3 of Form N-CSR, serving on its audit committee. The audit committee
         financial experts serving on the Registrant's audit committee are John
         H. Hewitt and Caleb Loring III, both of whom are "independent" pursuant
         to paragraph (a)(2) of Item 3 of Form N-CSR. Mr. Hewitt served at
         Morgan Stanley as a securities analyst and also in a supervisory role
         regarding analysis. He has held a chartered financial analyst
         designation, as well as a master's degree in business administration
         from Harvard University. He has been a member of the Registrant's audit

         audit committee since its inception, and has served on the audit
         committees of several privately held companies.

ITEM 4.  PRINCIPAL ACCOUNTANT FEES AND SERVICES.

         (a)  AUDIT FEES: The aggregate fees billed for professional services
              rendered by the principal accountant, PricewaterhouseCoopers LLP,
              for the audit of the Registrant's annual financial statements or
              services that are normally provided by the accountant in
              connection with statutory and regulatory filings for 2004 and 2003
              were $130,555 and $127,776, respectively.

         (b)  AUDIT RELATED FEES: The aggregate fees billed for audit-related
              professional services rendered by PricewaterhouseCoopers LLP for
              2004 and 2003 were $40,356 and $39,290, respectively. Such
              services and related fees for 2004 and 2003 included the
              preparation of fiscal year end tax provisions and distribution
              requirements necessary to prepare annual financial statements.

         (c)  TAX FEES: The aggregate fees billed for professional services
              rendered by PricewaterhouseCoopers LLP for tax compliance, tax
              advice, and tax planning for 2004 and 2003 were $96,205 and
              $92,214, respectively. Services rendered in both years 2003
              included asset diversification testing, the preparation of tax
              returns and extensions, the review of periodic distributions and,
              in 2003, tax advice related to the proper tax treatment of
              investments in total return swaps.

         (d)  ALL OTHER FEES: No such fees were billed to the Registrant by
              PricewaterhouseCoopers LLP for 2004 or 2003.

         (e)  (1) AUDIT COMMITTEE PRE-APPROVAL POLICY: The Registrant's audit
              committee pre-approves all audit and non-audit services to be
              performed by the Registrant's accountant before the accountant is
              engaged by the Registrant to perform such services.



         (e)  (2) 100% of the services described in each of paragraphs (b)
              through (d) of this Item 4 were pre-approved by the Registrant's
              audit committee before the accountant was engaged by the
              Registrant to perform such services.

         (f)  Not applicable.

         (g)  The aggregate non-audit fees billed by the Registrant's accountant
              for services rendered to the Registrant's investment adviser by
              PricewaterhouseCoopers LLP for 2004 and 2003 were $31,000 and
              $50,925, respectively. Services provided in 2004 included the
              review and documentation of the Registrant's change in custodian
              and fund accounting agent and the review and issuance of consent
              related to the registration and filing of a new fund on Form N-1A.
              Services provided in 2003 included consultation and discussions
              regarding the tax implications resulting from the Registrant's
              change of custodian and fund administrator, including change in
              partnership allocation methodology for funds in a master feeder
              structure and state tax issues concerning domicile of master
              portfolios. The aggregate non-audit fees billed by the
              Registrant's accountant for services rendered to the Registrant's
              transfer agent by PricewaterhouseCoopers LLP for 2004 were
              $43,708. Services provided in 2004 included a review of the
              transfer agency function and to issue a report under Rule
              17Ad-13(a)(3) of the Securities and Exchange Act of 1934. In 2003,
              the Registrant's transfer agent was not an entity controlling,
              controlled by, or under common control with the Registrant's
              investment adviser.

         (h)  Because all of the non-audit services rendered to the Registrant's
              investment adviser or any entity controlling, controlled by, or
              under common control with the investment adviser that provides
              ongoing services to the registrant were pre-approved by the
              Registrant's Audit Committee of the Board of Directors and no such
              non-audit services were not pre-approved, the Audit Committee was
              not asked to consider whether the provision of non-audit services
              rendered to the Registrant's investment adviser or any entity
              controlling, controlled by, or under common control with the
              investment adviser that provides ongoing services to the
              registrant which were not pre-approved by the Registrant's Audit
              Committee is compatible with maintaining the principal
              accountant's independence.

         Not applicable to the Registrant.

ITEM 6.  SCHEDULE OF INVESTMENTS
