(a)  Total returns and performance graph information represent past performance
     and are not indicative of future results, which may be lower or higher than
     performance data quoted. Investment return and principal value of an
     investment will fluctuate so that an investor's share, when redeemed, may
     be worth more or less than its original cost. The graph and table above do
     not reflect the deduction of taxes that a shareholder would pay on fund
     distributions or the redemption of fund shares.
(b)  The Standard & Poor's 500 Composite Stock Price Index ("S&P 500(R) Index")

     general.

STATE STREET EQUITY 500 INDEX FUND

EXPENSE EXAMPLE

As a shareholder of the State Street Equity 500 Index Fund (the "Fund"), you
incur ongoing costs, which include costs for administrative services and
distribution (12b-1) fees, among others, in addition to the Fund's proportionate
share of expenses of the State Street Equity 500 Index Portfolio. 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 made at the beginning of the
period shown and held for the entire period from July 1, 2004 to December 31,
2004.

The table below illustrates your Fund's costs in two ways:

- - BASED ON ACTUAL FUND RETURN. This section helps you to estimate the actual
  expenses that you paid over the period. The "Ending Account Value" shown is
  derived from the actual return of each class of the Fund, and the third column
  shows the dollar amount that would have been paid by an investor who started
  with $1,000 in the indicated Class. You may use the information here, together
  with the amount you invested, to estimate the expenses that you paid over the
  period.

  To do so, simply divide your account value by $1,000 (for example, an $8,600
  account value divided by $1,000 = 8.6), then multiply the result by the number
  given for the Class under the heading "Expenses Paid During Period".

- - BASED ON HYPOTHETICAL 5% RETURN. This section is intended to help you compare
  your Class's costs with those of other mutual funds. It assumes that the Class
  had a yearly return of 5% before expenses, but that the expense ratio is
  unchanged. In this case -- because the return used is not the Class's actual
  return -- the results do not apply to your investment. The example is useful
  in making comparisons because the Securities and Exchange Commission requires
  all mutual funds to calculate expenses based on a 5% return. You can assess
  your Class's costs by comparing this hypothetical example with the
  hypothetical examples that appear in shareholder reports of other funds.

- ------------------------------------------------------------------------------------------------
</Table>

* The calculations are based on expenses incurred in the most recent fiscal
  period of each Class. The Administrative Shares and Service Shares annualized
  average weighted expense ratios as of December 31, 2004 were 0.245% and
  0.344%, respectively, which include each Class's proportionate share of the
  expenses of the State Street Equity 500 Index Portfolio. The dollar amounts
  shown as "Expenses Paid" are equal to the annualized average weighted expense
  ratio multiplied by the average account value over the period, multiplied by
  the number of days in the most recent six-month period, then divided by the
  number of days in the most recent 12-month period.

STATE STREET EQUITY 500 INDEX FUND

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004

1. ORGANIZATION

The State Street Institutional Investment Trust (the "Trust") is a registered
and diversified open-end investment company, as defined in the Investment
Company Act of 1940, as amended (the "1940 Act"), that was organized as a
business trust under the laws of the Commonwealth of Massachusetts on February
16, 2000. The Trust consists of the following diversified series: the State
Street Equity 500 Index Fund, the State Street Equity 400 Index Fund, the State
Street Equity 2000 Index Fund, the State Street MSCI(R) EAFE(R) Index Fund, the
State Street Aggregate Bond Index Fund, the State Street Institutional Liquid
Reserves Fund and the State Street U.S. Government Money Market Fund, each of
which is a separate diversified series of the Trust. Information presented in
these financial statements pertains only to the State Street Equity 500 Index
Fund (the "Fund"). Pursuant to the Trust's Declaration of Trust, the Trustees
are authorized to issue an unlimited number of shares, with no par value, of the
Fund.

The Fund commenced operations on April 18, 2001. As of December 31, 2004, the
Fund and the State Street Institutional Liquid Reserves Fund were the only
series of the Trust that had commenced operations. The Fund offers both
Administrative and Service shares (formerly Class A and B shares, respectively).
Administrative Shares commenced operations on April 18, 2001 and Service Shares
commenced operations on March 10, 2003.

The Fund invests all of its investable assets in interests in the State Street
Equity 500 Index Portfolio (the "Portfolio"). The investment objective and
policies of the Portfolio are the same as the Fund. The value of the Fund's
investment in the Portfolio reflects the Fund's proportionate interest in the
net assets of the Portfolio (7.702% at December 31, 2004). The performance of
the Fund is directly affected by the performance of the Portfolio. The financial
statements of the Portfolio, including the portfolio of investments, are
included elsewhere in this report and should be read in conjunction with the
Fund's financial statements.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of the significant accounting policies consistently
followed by the Fund in preparation of its financial statements.

SECURITY VALUATION: The Fund records its investment in the Portfolio at value.
The valuation policies of the Portfolio are discussed in Note 2 of the
Portfolio's Notes to Financial Statements, which are included elsewhere within
this report.

SECURITY TRANSACTIONS, INVESTMENT INCOME AND EXPENSES: Securities transactions
are recorded on a trade date basis. 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. Realized and unrealized gains and losses from security transactions
consist of the Fund's pro-rata share of the Portfolio's realized and unrealized
gains and

losses. Realized gains and losses from security transactions are recorded on the
basis of identified cost. Class specific distribution fees are borne by that
class. Income, non-class specific expenses, and realized and unrealized gains
and losses are allocated to the respective classes daily on the basis of
relative net assets.

DIVIDENDS AND DISTRIBUTIONS: Dividends, if any, are declared and paid, at least,
annually. Net realized capital gains, if any, are distributed annually, unless
additional distributions are required for compliance with applicable tax
regulations.

The tax character of distributions paid to shareholders during the years ended
December 31, 2004 and 2003 were as follows:

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

                                                             ------------
Total                                                        $  1,464,594
                                                             ============
</Table>

As of December 31, 2004, there were no significant differences between book
basis and tax basis components of net assets, other than differences
attributable to wash sale loss deferrals.

FEDERAL INCOME TAXES: The Fund intends to continue to qualify for and elect
treatment as a regulated investment company under Subchapter M of the Internal
Revenue Code of 1986, as amended. By so qualifying and electing, the Fund will
not be subject to federal income taxes to the extent it distributes its taxable
income, including any net realized capital gains, for each fiscal year. In
addition, by distributing during each calendar year substantially all of its net
taxable income and capital gains, if any, the Fund will not be subject to
federal excise tax.

Income and capital gain distributions are determined in accordance with income
tax regulations, which may differ from generally accepted accounting principles.
These book tax differences are primarily due to wash sales loss deferrals.

At December 31, 2004, the Fund had capital loss carry forwards in the amount of
$26,378,156, of which $18,165,550, $7,776,419, $78,263, and $357,924 may be
utilized to offset future net realized capital gains until expiration dates of
December 31, 2009, December 31, 2010, December 31, 2011, and December 31, 2012,
respectively. No post-October losses were deferred in the current year.

At December 31, 2004, the cost of investments computed on a federal income tax
basis was $185,322,451, resulting in $27,832,104 of unrealized appreciation. The
differences between book and tax cost amounts are primarily due to wash sales
loss deferrals.

USE OF ESTIMATES: The Fund's financial statements are prepared in accordance
with U.S. generally accepted accounting principles that require the use of
management estimates. Actual results could differ from those estimates.

3. RELATED PARTY FEES AND TRANSACTIONS

officers and trustees are indemnified against certain liabilities arising out of
the performance of their duties to the Trust. In addition, both in some of its
principal service contracts and in the normal course of its business, the Trust

   REPORT OF ERNST & YOUNG LLP, INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of State Street Institutional Investment Trust and
Shareholders of State Street Equity 500 Index Fund:

We have audited the accompanying statement of assets and liabilities of the
State Street Equity 500 Index Fund (one of the funds constituting State Street
Institutional Investment Trust)(the Fund) as of December 31, 2004, and the
related statement of operations for the year then ended, and the statements of
changes in net assets for each of the two years in the period then ended and the
financial highlights for each of the periods indicated therein. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits 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 and financial highlights are free of material misstatement. An audit
includes consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the Fund's
internal control over financial reporting. Accordingly, we express no such
opinion. An audit also includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
Our procedures included confirmation of securities owned as of December 31,
2004, by correspondence with the custodian. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
State Street Equity 500 Index Fund of the State Street Institutional Investment
Trust at December 31, 2004, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and the financial highlights for each of the periods indicated
therein, in conformity with U.S. generally accepted accounting principles.

                                                           /s/ Ernst & Young LLP

                               DECEMBER 31, 2004


STATE STREET EQUITY 500 INDEX PORTFOLIO

MANAGEMENT DISCUSSION OF FUND PERFORMANCE AND ANALYSIS

THE PORTFOLIO

The State Street Equity 500 Index Portfolio's (the "Portfolio") investment
objective is to replicate as closely as possible, before expenses, the
performance of the Standard & Poor's 500 Composite Stock Price Index (the "S&P
500(R) Index"). The Portfolio uses a passive management strategy designed to
track the performance of the S&P 500(R) Index. The S&P 500(R) Index is a
well-known unmanaged stock market index that includes common stocks of 500
companies from several industrial sectors representing a significant portion of
the market value of all stocks publicly traded in the United States.

For the year ended December 31, 2004, the Portfolio gained 10.86%. For the same
period, the S&P 500(R) Index gained 10.88%.

THE MARKET

The S&P 500(R) Index finished strong for the year, ending 2004 with a solid
10.88% gain. After a rocky third quarter, equities dramatically picked up in
October when a number of solid corporate profit reports led investors to
maintain positions in the face of a renewed surge in crude oil. In November, the
Index returned 4.1%. When the U.S. presidential election was decided quickly and
without controversy, the bulls mounted a fresh stampede to the upside. The rally
continued into December with additional gains of 3.4%. This was extremely good
news after experiencing small positive returns in the first half of the year and
a difficult market during most of the third quarter. The equity market sank in
July and August, weighted by second-quarter earnings releases that failed to
offer enough enthusiasm regarding the second half of the year, a weak July jobs
report and a sharp rise in crude oil prices.

All ten economic sectors represented in the S&P 500(R) Index posted positive
results for the year. Energy and Utilities had the highest total returns, while
Financials, Industrials and Energy were the greatest contributors to the Index's
return. Financials, Industrials, and Energy were bolstered by the respective
strengths of Bank of America Corp., General Electric Co. and ExxonMobil Corp.
During the second quarter, Bank of America Corp. benefited from its expanded
customer base resulting from its merger with FleetBoston and new focus on its
higher-margin consumer loan department. General Electric Corp. had a share
increase from an acquisition in April, and also moved from being solely a growth
stock in the Russell Indexes to mostly value, leading to increased demand from
indexers. Not surprisingly, Energy was a top performer this year due to surging
oil prices, which fueled investor optimism and brought in a total return of
31.24% for the Index.

Health Care was the weakest performing sector for the year as threats of
competition from drug imports and concerns about declining new-product pipelines
punished some of the larger companies within this segment. In late September,
Merck & Co. Inc. recalled its multi-billion dollar arthritis drug Vioxx after
research concluded that the drug doubled the risk of heart attack or stroke.
Pfizer, Inc. also trailed the overall sector after the company lowered its
revenue expectations for the quarter. Additionally, risk surrounding the
presidential election weighed heavily on drug stocks. Information Technology was
not far behind Health Care, having been the worst-performing sector of the
market during the third quarter

of 2004, as measured by the S&P 500(R) Index. In general, many of the more
speculative companies in this sector fell due to lackluster domestic spending on
technology.

The top contributors to the Index's return for the 12 month period ending
December 31, 2004 were ExxonMobil Corp, General Electric Co. and Johnson &
Johnson, while Pfizer, Inc., Intel Corp. and Cisco Systems, Inc. were the
largest detractors.

The top three performing stocks in the Index for the year 2004 were Autodesk
Inc., Apple Computer Inc., and TXU Corp. The bottom three performing stocks in
the Index for the year 2004 were Winn-Dixie Stores, CIENA Corp. and PMC-Sierra
Inc.

STATE STREET EQUITY 500 INDEX PORTFOLIO

EXPENSE EXAMPLE

As a shareholder of the State Street Equity 500 Index Portfolio (the
"Portfolio"), you incur ongoing costs, which include costs for portfolio
management and administrative services, among others. This example is intended
to help you understand your ongoing costs (in dollars) of investing in the
Portfolio 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 made at the beginning of the
period shown and held for the entire period from July 1, 2004 to December 31,
2004.

The table below illustrates your Portfolio's costs in two ways:

     - BASED ON ACTUAL FUND RETURN. This section helps you to estimate the
       actual expenses that you paid over the period. The "Ending Account Value"
       shown is derived from the actual return of the Portfolio, and the third
       column shows the dollar amount that would have been paid by an investor
       who started with $1,000 in the Portfolio. You may use the information
       here, together with the amount you invested, to estimate the expenses
       that you paid over the period.

      To do so, simply divide your account value by $1,000 (for example, an
      $8,600 account value divided by $1,000 = 8.6), then multiply the result by
      the number given for the Portfolio under the heading "Expenses Paid During
      Period".

     - BASED ON HYPOTHETICAL 5% RETURN. This section is intended to help you
       compare your Portfolio's costs with those of other mutual funds. It
       assumes that the Portfolio had a yearly return of 5% before expenses, but
       that the expense ratio is unchanged. In this case- because the return
       used is not the Portfolio's actual return- the results do not apply to
       your investment. The example is useful in making comparisons because the
       Securities and Exchange Commission requires all mutual funds to calculate

       appear in shareholder reports of other funds.

* The calculations are based on expenses incurred in the most recent fiscal
  period of the Portfolio. The annualized average weighted expense ratio as of
  December 31, 2004 was 0.045% . The dollar amounts shown as "Expenses Paid" are
  equal to the annualized average weighted expense ratio multiplied by the
  average account value over the period, multiplied by the number of days in the
  most recent six-month period, then divided by the number of days in the most
  recent 12-month period.

STATE STREET EQUITY 500 INDEX PORTFOLIO

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004

1. ORGANIZATION

The State Street Master Funds (the "Trust") is a registered and diversified
open-end investment company, as defined in the Investment Company Act of 1940,
as amended (the "1940 Act"), that was organized as a business trust under the
laws of the Commonwealth of Massachusetts on July 27, 1999. The Trust comprises
seven investment portfolios: the State Street Equity 500 Index Portfolio, the
State Street Equity 400 Index Portfolio, the State Street Equity 2000 Index
Portfolio, the State Street MSCI(R) EAFE(R) Index Portfolio, the State Street
Aggregate Bond Index Portfolio, the State Street Money Market Portfolio, and the
State Street U.S. Government Money Market Portfolio. Information presented in
these financial statements pertains only to the State Street Equity 500 Index
Portfolio (the "Portfolio"). At December 31, 2004, only the Portfolio, State
Street MSCI(R) EAFE(R) Index Portfolio and State Street Money Market Portfolio
had commenced operations. Pursuant to the Trust's Declaration of Trust, the
Board of Trustees may issue an unlimited number of non-transferable beneficial
interests.

The Portfolio's investment objective is to replicate, as closely as possible,
before expenses, the performance of the Standard & Poor's 500 Composite Stock
Price Index (the "S&P 500(R) Index"). The Portfolio uses a passive management
strategy designed to track the performance of the S&P 500(R) Index. The S&P
500(R) Index is a well-known, unmanaged, stock index that includes common stocks
of 500 companies from several industrial sectors representing a significant
portion of the market value of all stocks publicly traded in the United States.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of the significant accounting policies consistently
followed by the Portfolio in the preparation of its financial statements.

SECURITY VALUATION: The Portfolio's investments are valued each business day by
independent pricing services. Equity securities for which market quotations are
available are valued at the last sale price or official closing price (closing
bid price if no sale has occurred) on the primary market or exchange on which
they trade. Investments in other mutual funds are valued at the net asset value
per share. Fixed-income securities and options are valued on the basis of the
closing bid price. Futures contracts are valued on the basis of the last sale
price. Money market instruments maturing within 60 days of the valuation date
are valued at amortized cost, a method by which each money market instrument is
initially valued at cost, and thereafter a constant accretion or amortization of
any discount or premium is recorded until maturity of the security. The
Portfolio may value securities for which market quotations are not readily
available at "fair value," as determined in good faith pursuant to procedures
established by the Board of Trustees.

STATE STREET EQUITY 500 INDEX PORTFOLIO

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 2004

SECURITIES TRANSACTIONS, INVESTMENT INCOME AND EXPENSES: Securities transactions
are recorded on a trade date basis. Dividend income is recorded on the
ex-dividend date. Interest income is recorded daily on the accrual basis and
includes amortization of premium and accretion of discount on investments.
Realized gains and losses from securities transactions are recorded on the basis
of identified cost. Expenses are accrued daily based on average daily net
assets.

All of the net investment income and realized and unrealized gains and losses
from the security transactions of the Portfolio are allocated pro rata among the
partners in the Portfolio based on each partner's daily ownership percentage.

FEDERAL INCOME TAXES: The Portfolio is not required to pay federal income taxes
on its net investment income and net capital gains because it is treated as a
partnership for federal income tax purposes. All interest, dividends, gains and
losses of the Portfolio are deemed to have been "passed through" to the
Portfolio's partners in proportion to their holdings in the Portfolio,
regardless of whether such items have been distributed by the Portfolio. Each
partner is responsible for tax liability based on its distributive share;
therefore, no provision has been made for federal income taxes.

FUTURES: The Portfolio may enter into financial futures contracts as part of its
strategy to track the performance of the S&P 500(R) Index. Upon entering into a
futures contract, the Portfolio is required to deposit with the broker cash or
securities in an amount equal to a certain percentage of the contract amount.
Variation margin payments are made or received by the Portfolio each day,
depending on the daily fluctuations in the value of the underlying security or
index, and are recorded for financial statement purposes as unrealized gains or
losses by the Portfolio. The Portfolio recognizes a realized gain or loss when
the contract is closed. The Portfolio voluntarily segregates securities in an
amount equal to the outstanding value of the open futures contracts in
accordance with Securities and Exchange Commission (the "SEC") requirements.

The primary risks associated with the use of futures contracts are an imperfect
correlation between the change in market value of the securities held by the
Portfolio and the prices of futures contracts and the possibility of an illiquid
market.

SECURITIES LENDING: The Trust, on behalf of the Portfolio, entered into a
Securities Lending Agreement (the "Agreement") with State Street Bank and Trust
Company ("State Street"). Under the terms of the Agreement, the Portfolio may
lend portfolio securities to qualified borrowers in order to earn additional
income. The Agreement requires that loans are secured at all times by cash, U.S.
Government securities, sovereign debt, or irrevocable lines of credit in an
amount at least equal to 102% of the market value of domestic securities loaned
(105% in the case of foreign securities), plus accrued interest and dividends,
determined on a daily basis. Proceeds collected by State Street on investment of
cash collateral or any fee income is allocated as follows: 75% to the Portfolio
and 25% to State Street. For the year ended December 31, 2004, the earned income
for the Portfolio and State Street was $69,912 and $23,304, respectively.

STATE STREET EQUITY 500 INDEX PORTFOLIO

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 2004

The primary risk associated with securities lending is that if the borrower
defaults on its obligation to return the securities loaned because of insolvency
or other reasons, the Portfolio could experience delays and costs in recovering
the securities loaned or in gaining access to the collateral. At December 31,
2004, the value of the securities loaned amounted to $97,985,663. The loans were
collateralized with cash of $98,441,667, which the Portfolio then invested in
the State Street Navigator Securities Lending Prime Portfolio (the "Prime
Portfolio"), an affiliated investment company, and letters of credit from JP
Morgan Chase Bank and BNP Paribas in the amounts of $1,264,800 and $2,150,160,
respectively.

USE OF ESTIMATES: The Portfolio's financial statements are prepared in
accordance with U.S. generally accepted accounting principles that require the
use of management estimates. Actual results could differ from those estimates.

3. SECURITIES TRANSACTIONS

For the year ended December 31, 2004, purchases and sales of investment
securities, excluding short-term investments, futures contracts, and in-kind
withdrawals, aggregated to $237,412,033 and $297,872,960, respectively. The
aggregate value of in-kind withdrawals was $72,956,408.

At December 31, 2004, the tax cost of investments was $2,450,998,571. The
aggregate gross unrealized appreciation and gross unrealized depreciation was
$783,440,674 and $371,879,248, respectively, resulting in net appreciation of
$411,561,426 for all securities as computed on a federal income tax basis. The
differences between book and tax cost amounts are primarily due to wash sale
loss deferrals.

SSgA FM's services as investment adviser and for State Street's services as

5. INDEMNIFICATIONS

officers and trustees are indemnified against certain liabilities arising out of
the performance of their duties to the Trust. In addition, both in some of its
principal service contracts and in the normal course of its business, the Trust

types of losses or liabilities. The Trust's maximum exposure under these
arrangements in unknown as this could involve future claims against the Trust.

   REPORT OF ERNST & YOUNG LLP, INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of State Street Master Funds and
Owners of Beneficial Interest of State Street Equity 500 Index Portfolio:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the State Street Equity 500 Index Portfolio
(one of the portfolios constituting State Street Master Funds)(the Portfolio) as
of December 31, 2004, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended and the financial highlights for each of the periods indicated
therein. These financial statements and financial highlights are the
responsibility of the Portfolio's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits 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 and financial highlights are free of material misstatement. An audit
includes consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the
Portfolio's internal control over financial reporting. Accordingly, we express
no such opinion. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements and financial
highlights, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
Our procedures included confirmation of securities owned as of December 31,
2004, by correspondence with the custodian and brokers or other appropriate
auditing procedures where replies from the brokers were not received. We believe
that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
State Street Equity 500 Index Portfolio of State Street Master Funds at December
31, 2004, the results of its operations for the year then ended, the changes in
its net assets for each of the two years in the period then ended and the
financial highlights for each of the periods indicated therein, in conformity
with U.S. generally accepted accounting principles.

                                                           /s/ Ernst & Young LLP

                                DECEMBER 31, 2004


STATE STREET INSTITUTIONAL LIQUID RESERVES FUND

EXPENSE EXAMPLE

As a shareholder of the State Street Institutional Liquid Reserves Fund (the
"Fund"), you incur ongoing costs, which include costs for administrative
services and distribution (12b-1) fees, among others, in addition to the Fund's
proportionate share of expenses of the State Street Money Market Portfolio. 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 made at the beginning of the
period shown and held for the entire period from August 12, 2004 (commencement
of operations) to December 31, 2004.

The table below illustrates your Fund's costs in two ways:

      -     BASED ON ACTUAL FUND RETURN. This section helps you to estimate the
            actual expenses that you paid over the period. The "Ending Account
            Value" shown is derived from the Fund's actual return, and the third
            column shows the dollar amount that would have been paid by an
            investor who started with $1,000 in the Fund. You may use the
            information here, together with the amount you invested, to estimate
            the expenses that you paid over the period.

            To do so, simply divide your account value by $1,000 (for example,
            an $8,600 account value divided by $1,000 = 8.6), then multiply the
            result by the number given for the Fund under the heading "Expenses
            Paid During Period".

      -     BASED ON HYPOTHETICAL 5% RETURN. This section is intended to help
            you compare your Fund's costs with those of other mutual funds. It
            assumes that the Fund had a yearly return of 5% before expenses, but
            that the expense ratio is unchanged. In this case- because the
            return used is not the Fund's actual return- the results do not
            apply to your investment. The example is useful in making
            comparisons because the Securities and Exchange Commission requires
            all mutual funds to calculate expenses based on a 5% return. You can
            assess your Fund's costs by comparing this hypothetical example with
            the hypothetical examples that appear in shareholder reports of
            other funds.

expenses)


* The calculations are based on expenses incurred in the most recent fiscal
period of the Fund. The Fund's annualized average weighted expense ratio as of
December 31, 2004 was 0.150%, which includes the Fund's proportionate share of
the expenses of the State Street Money Market Portfolio. The dollar amounts
shown as "Expenses Paid" are equal to the annualized average weighted expense
ratio multiplied by the average account value over the period, multiplied by the
number of days in the most recent period (from August 12, 2004 (commencement of
operations) to December 31, 2004), then divided by the number of days in the
most recent 12-month period.

(a) The per share amounts and percentages reflect income and expenses assuming
    inclusion of the Fund's proportionate share of income and expenses of the
    State Street Money Market Portfolio.

(b) Total return is calculated assuming a purchase of shares at net asset
    value on the first day and a sale at net asset value on the last day of
    each period reported. Distributions are assumed, for the purpose of this
    calculation, to be reinvested at net asset value per share on the
    respective payment dates. Total return for periods of less than one year
    is not annualized. Results represent past performance and are not

STATE STREET INSTITUTIONAL LIQUID RESERVES FUND

NOTES TO FINANCIAL STATEMENT

DECEMBER 31,2004

1. ORGANIZATION

The State Street Institutional Investment Trust (the "Trust") is a registered
and diversified open-end investment company, as defined in the Investment
Company Act of 1940, as amended (the "1940 Act"), that was organized as a
business trust under the laws of the Commonwealth of Massachusetts on February
16, 2000. The Trust consists of the following diversified series: the State
Street Equity 500 Index Fund, the State Street Equity 400 Index Fund, the State
Street Equity 2000 Index Fund, the State Street MSCI(R) EAFE(R) Index Fund, the
State Street Aggregate Bond Index Fund, the State Street Institutional Liquid
Reserves Fund and the State Street U.S. Government Money Market Fund, each of
which is a separate diversified series of the Trust. Information presented in
these financial statements pertains only to the State Street Institutional
Liquid Reserves Fund (the "Fund"). Pursuant to the Trust's Declaration of Trust,
the Trustees are authorized to issue an unlimited number of shares, with no par
value, of the Fund.

The Fund commenced operations on August 12, 2004. As of December 31, 2004, the
Fund and the State Street Equity 500 Index Fund were the only series of the
Trust that had commenced operations.

It is the policy of the Fund to maintain a continous net asset value per share
of $1.00; the Fund has adopted certain investment, valuation, and dividend and
distribution policies, which conform to general industry practice, to enable it
to do so. However, there is no assurance the Fund will be able to maintain a
stable net asset value per share.

The Fund invests all of its investable assets in interests in the State Street
Money Market Portfolio (the "Portfolio"). The investment objective and policies
of the Portfolio are the same as the Fund. The value of the Fund's investment in
the Portfolio reflects the Fund's proportionate interest in the net assets of
the Portfolio (99.99% at December 31, 2004). The performance of the Fund is
directly affected by the performance of the Portfolio. The financial statements
of the Portfolio, including the portfolio of investments, are included elsewhere
in this report and should be read in conjunction with the Fund's financial
statements.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of the significant accounting policies consistently
followed by the Fund in the preparation of its financial statements.

SECURITY VALUATION - The Fund records its investment in the Portfolio at value.
The valuation policies of the Portfolio are discussed in Note 2 of the
Portfolio's Notes to Financial Statements, which are included elsewhere within
this report.

SECURITY TRANSACTIONS, INVESTMENT INCOME AND EXPENSES - Securities transactions
are recorded on a trade date basis. 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. Realized gains and losses from security transactions consist of the
Fund's pro-rata share

STATE STREET INSTITUTIONAL LIQUID RESERVES FUND

NOTES TO FINANCIAL STATEMENTS

of the Portfolio's realized gains and losses. Realized gains and losses from
security transactions are recorded on the basis of identified cost.

DIVIDENDS AND DISTRIBUTIONS - Dividends from net investment income are declared
daily and are payable as of the last business day of each month. Net realized
capital gains, if any, are distributed annually, unless additional distributions
are required for compliance with applicable tax regulations. The tax character
of distributions paid to shareholders during the period ended December 31, 2004
was $2,055,090 of ordinary income. At December 31, 2004, the components of
distributable earnings on a tax basis were as follows:

      Undistributed ordinary income $ 0

FEDERAL INCOME TAXES - The Fund intends to qualify for and elect treatment as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986, as amended. By so qualifying and electing, the Fund will not be subject to
federal income taxes to the extent it distributes its taxable income, including
any net realized capital gains, for each fiscal year. In addition, by
distributing during each calendar year substantially all of its net taxable
income and capital gains, if any, the Fund will not be subject to federal excise
tax.

Income and capital gain distributions are determined in accordance with income
tax regulations, which may differ from generally accepted accounting principles.

EXPENSE ALLOCATION: Certain expenses are applicable to multiple Portfolios and
Funds. Expenses directly attributable to a Portfolio or Fund are charged to that
Portfolio or Fund. Expenses of the Trust that are not directly attributed to a
Fund are allocated among the Funds, on the basis of relative net assets, except
where a more appropriate allocation of expenses to each of the Funds can
otherwise be made fairly.

USE OF ESTIMATES: The Fund's financial statements are prepared in accordance
with U.S. generally accepted accounting principles that require the use of
management estimates. Actual results could differ from those estimates.

3. RELATED PARTY FEES

The Portfolio retains SSgA Funds Management, Inc. ("SSgA FM"), a subsidiary of
State Street Corporation and an affiliate of State Street Bank and Trust Company
("State Street"), as its investment adviser. For such investment advisory
services, the Portfolio pays SSgA FM a fee at the annual rate of 0.10% of its
average daily net assets.

SSgA FM has contractually agreed to cap the total operating expenses of the Fund
(not including the pass-through expenses of the Portfolio) on an annual basis at
0.05% of the Fund's average daily net assets until April 30, 2005. For the
period ended December 31, 2004, SSgA FM reimbursed the Fund $97,420 under this
agreement. There is no agreement in place for SSgA FM to recover operating
expenses previously waived or reimbursed.

State Street serves as the Fund's administrator, custodian and transfer agent.
The Fund pays State Street annual fees of $25,000 for administration services,
$12,000 for custody and accounting services, and $30,000 for transfer agency
services plus transaction fees.

ALPS Distributors, Inc. serves as Distributor (the "Distributor") pursuant to a
Distribution Agreement with the Trust.

The Trust has adopted a plan of distribution pursuant to Rule 12b-1 under the
1940 Act (the "Rule 12b-1 Plan"). Under the Rule 12b-1 Plan, the Fund may
compensate financial intermediaries in connection with the distribution of Fund
shares and for services provided to the Fund's shareholders. The Rule 12b-1 Plan
calls for payments at an annual rate of up to 0.05% of daily average net assets.
For the period ended December 31, 2004, the Fund accrued State Street Global
Markets LLC, an affiliated company of State Street, $61,668 for services
provided to the Fund's shareholders.

4. INDEMNIFICATIONS

Like many other companies, the Trust's organizational documents provide that its
officers and trustees are indemnified against certain liabilities arising out of
the performance of their duties to the Trust. In addition, both in some of its
principal service contracts and in the normal course of its business, the Trust
enters into contracts that provide indemnifications to other parties for certain
types of losses or liabilities. The Trust's maximum exposure under these
arrangements in unknown as this could involve future claims against the Trust.

5. SUBSEQUENT EVENT

Effective February 1, 2005, ALPS Distributors, Inc. will replace State Street as
transfer agent for the Fund. The fees for transfer agent services with ALPS will
be materially the same as the fees with State Street.

STATE STREET INSTITUTIONAL LIQUID RESERVES FUND

   REPORT OF ERNST & YOUNG LLP, INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of State Street Institutional Investment Trust and
Shareholders of State Street Institutional Liquid Reserves Fund:

We have audited the accompanying statement of assets and liabilities of the
State Street Institutional Liquid Reserves Fund (one of the funds constituting
State Street Institutional Investment Trust)(the Fund) as of December 31, 2004,
and the related statement of operations, the statement of changes in net assets,
and the financial highlights for the period from August 12, 2004 (commencement
of operations) to December 31, 2004. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audit.

We conducted our audit 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 and financial highlights are free of material misstatement. An audit
includes consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the Fund's
internal control over financial reporting. Accordingly, we express no such
opinion. An audit also includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
Our procedures included confirmation of securities owned as of December 31,
2004, by correspondence with the custodian. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
State Street Institutional Liquid Reserves Fund of the State Street
Institutional Investment Trust at December 31, 2004, the results of its
operations, the changes in its net assets and financial highlights for the
period from August 12, 2004 (commencement of operations) to December 31, 2004,
in conformity with U.S. generally accepted accounting principles.

                                                               Ernst & Young LLP

STATE STREET MONEY MARKET PORTFOLIO

EXPENSE EXAMPLE

As a shareholder of the State Street Money Market Portfolio (the "Portfolio"),
you incur ongoing costs, which include costs for portfolio management and
administrative services, among others. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Portfolio 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 made at the beginning of the
period shown and held for the entire period from August 12, 2004 (commencement
of operations) to December 31, 2004.

The table below illustrates your Portfolio's costs in two ways:

      -     BASED ON ACTUAL FUND RETURN. This section helps you to estimate the
            actual expenses that you paid over the period. The "Ending Account
            Value" shown is derived from the Portfolio's actual return, and the
            third column shows the dollar amount that would have been paid by an
            investor who started with $1,000 in the Portfolio. You may use the
            information here, together with the amount you invested, to estimate
            the expenses that you paid over the period.

            To do so, simply divide your account value by $1,000 (for example,
            an $8,600 account value divided by $1,000 = 8.6), then multiply the
            result by the number given for the Portfolio under the heading
            "Expenses Paid During Period".

      -     BASED ON HYPOTHETICAL 5% RETURN. This section is intended to help
            you compare your Portfolio's costs with those of other mutual funds.
            It assumes that the Portfolio had a yearly return of 5% before
            expenses, but that the expense ratio is unchanged. In this case-
            because the return used is not the Portfolio's actual return- the
            results do not apply to your investment. The example is useful in
            making comparisons because the Securities and Exchange Commission
            requires all mutual funds to calculate expenses based on a 5%
            return. You can assess your Portfolio's costs by comparing this
            hypothetical example with the hypothetical examples that appear in
            shareholder reports of other funds.

EXPENSES)             $1,000.00         $1,019.01           $ 0.39


* The calculations are based on expenses incurred in the most recent fiscal
period of the Portfolio. The Portfolio's annualized average weighted expense
ratio as of December 31, 2004 was 0.100%. The dollar amounts shown as "Expenses
Paid" are equal to the annualized average weighted expense ratio multiplied by
the average account value over the period, multiplied by the number of days in
the most recent period (from August 12, 2004 (commencement of operations) to
December 31, 2004), then divided by the number of days in the most recent
12-month period.

STATE STREET MONEY MARKET PORTFOLIO
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2004

1. ORGANIZATION

The State Street Master Funds (the "Trust") is a registered and diversified
open-end investment company, as defined in the Investment Company Act of 1940,
as amended (the "1940 Act"), that was organized as a business trust under the
laws of the Commonwealth of Massachusetts on July 27, 1999. The Trust comprises
seven investment portfolios: the State Street Equity 500 Index Portfolio, the
State Street Equity 400 Index Portfolio, the State Street Equity 2000 Index
Portfolio, the State Street MSCI(R) EAFE(R) Index Portfolio, the State Street
Aggregate Bond Index Portfolio, the State Street Money Market Portfolio, and the
State Street U.S. Government Money Market Portfolio. Information presented in
these financial statements pertains only to the State Street Money Market
Portfolio (the "Portfolio"). At December 31, 2004, only the Portfolio, State
Street Equity 500 Index Portfolio and State Street MSCI(R) EAFE(R) Index
Portfolio had commenced operations. The Portfolio commenced operations on August
12, 2004. Pursuant to the Trust's Declaration of Trust, the Board of Trustees
may issue an unlimited number of non-transferable beneficial interests.

The Portfolio's investment objective is to maximize current income to the extent
consistent with the preservation of capital and liquidity by investing in dollar
denominated securities.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of the significant accounting policies consistently
followed by the Portfolio in the preparation of its financial statements.

SECURITY VALUATION: As permitted under Rule 2a-7 of the 1940 Act and certain
conditions therein, securities are valued initially at cost and thereafter
assume a constant amortization to maturity of any discount or premium.

SECURITIES TRANSACTIONS, INVESTMENT INCOME AND EXPENSES: Securities transactions
are recorded on a trade date basis. Interest income is recorded daily on the
accrual basis and includes amortization of premium and accretion of discount on
investments. Realized gains and losses from securities transactions are recorded
on the basis of identified cost. Expenses are accrued daily.

All of the net investment income and realized gains and losses from the security
transactions of the Portfolio are allocated pro rata among the partners in the
Portfolio based on each partner's daily ownership percentage.

FEDERAL INCOME TAXES: The Portfolio is not required to pay federal income taxes
on its net investment income and net capital gains because it is treated as a
partnership for federal income tax purposes. All interest, gains and losses of
the Portfolio are deemed to have been "passed through" to the Portfolio's
partners in proportion to their holdings in the Portfolio, regardless of whether
such items have been distributed by the Portfolio. Each partner is responsible
for tax liability based on its distributive share; therefore, no provision has
been made for federal income taxes.

STATE STREET MONEY MARKET PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004

At December 31, 2004, the cost of investments for federal income tax purposes
was the same as the cost for financial reporting purposes.

REPURCHASE AGREEMENTS: A repurchase agreement customarily obligates the seller
at the time it sells securities to the Portfolio to repurchase the securities at
a mutually agreed upon price and time which, in the case of the Portfolio's
transactions, is within seven days. The total amount received by the Portfolio
on repurchase is calculated to exceed the price paid by the Portfolio,
reflecting an agreed-upon market rate of interest for the period of time to the
settlement date, and is not necessarily related to the interest rate on the
underlying securities. The underlying securities are ordinarily United States
Government securities, but may consist of other securities in which the
Portfolio is permitted to invest. Repurchase agreements are fully collateralized
at all times. The use of repurchase agreements involves certain risks. For
example, if the seller of securities under a repurchase agreement defaults on
its obligation to repurchase the underlying securities (as a result of its
bankruptcy or otherwise) the Portfolio will seek to dispose of such securities;
this action could involve costs or delays. The Portfolio may enter into
repurchase agreements maturing within seven days with domestic dealers, banks
and other financial institutions deemed to be creditworthy by SSgA Funds
Management, Inc. ("SSgA FM"), a subsidiary of State Street Corporation and an
affiliate of State Street Bank and Trust Company ("State Street").

EXPENSE ALLOCATION: Certain expenses are applicable to multiple Portfolios and
Funds. Expenses directly attributable to a Portfolio or Fund are charged to that
Portfolio or Fund. Expenses of the Trust that are not directly attributed to a
Portfolio are allocated among the Portfolios, on the basis of relative net
assets, except where a more appropriate allocation of expenses to each of the
Portfolios can otherwise be made fairly.

USE OF ESTIMATES: The Portfolio's financial statements are prepared in
accordance with U.S. generally accepted accounting principles that require the
use of management estimates. Actual results could differ from those estimates.

3. RELATED PARTY FEES

The Portfolio has entered into an investment advisory agreement with SSgA FM
(the "Adviser"). The Adviser directs the investments of the Portfolio in
accordance with its investment objective, policies, and limitations. In
compensation for the Adviser's services as investment adviser, the Portfolio
pays the Adviser an annual fee of 0.10% of the Portfolio's average daily net
assets. The Adviser has contractually agreed to cap the total operating expenses
of the Portfolio at 0.10% of the Portfolio's average daily net assets until
April 30, 2005. For the period ended December 31, 2004, SSgA FM reimbursed the
Portfolio $102,591 under this agreement. There is no agreement in place for SSgA
FM to recover operating expenses previously waived or reimbursed.

STATE STREET MONEY MARKET PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2004

State Street is the administrator, custodian and transfer agent for the
Portfolio. In compensation for State Street's services as administrator,
custodian and transfer agent, the Portfolio pays State Street an annual fee of
the average daily net assets as follows:



                                       Annual percentage of
Asset Levels                         average daily net assets
- ------------                         --------------------------
                                  
First $200 Million                   0.04%
Next $200 Million                    0.03
Thereafter                           0.02

Minimum annual fee:
Assets of $500 million and less      $150,000
Assets of $500 million - $2 billion  $200,000 with 0.01% waiver


State Street has contractually agreed to waive 0.01% of its fees on an annual
basis when the Portfolio's assets are between $500 million and $2 billion. For
the period ended December 31, 2004, no amounts were waived under this agreement.

4. TRUSTEES' FEES

The Trust pays each trustee who is not an officer or employee of SSgA FM or
State Street $2,500 for each meeting of the Board of Trustees and an additional
$500 for each telephonic meeting attended. The Trust also pays each trustee an
annual retainer of $20,000. Each trustee is reimbursed for out-of-pocket and
travel expenses. The Portfolio reimburses State Street or its affiliates for its
pro-rata share of the total fees.

5. INDEMNIFICATIONS

Like many other companies, the Trust's organizational documents provide that its
officers and trustees are indemnified against certain liabilities arising out of
the performance of their duties to the Trust. In addition, both in some of its
principal service contracts and in the normal course of its business, the Trust
enters into contracts that provide indemnifications to other parties for certain
types of losses or liabilities. The Trust's maximum exposure under these
arrangements in unknown as this could involve future claims against the Trust.

STATE STREET MONEY MARKET PORTFOLIO

   REPORT OF ERNST & YOUNG LLP, INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of State Street Master Funds and
Owners of Beneficial Interest of State Street Money Market Portfolio:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the State Street Money Market Portfolio (one of
the portfolios constituting State Street Master Funds)(the Portfolio) as of
December 31, 2004, and the related statement of operation, the statement of
changes in net assets, and financial highlights for the period from August 12,
2004 (commencement of operations) to December 31, 2004. These financial
statements and financial highlights are the responsibility of the Portfolio's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit.

We conducted our audit 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 and financial highlights are free of material misstatement. An audit
includes consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the
Portfolio's internal control over financial reporting. Accordingly, we express
no such opinion. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements and financial
highlights, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
Our procedures included confirmation of securities owned as of December 31,
2004, by correspondence with the custodian and brokers. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
State Street Money Market Portfolio of State Street Master Funds at December 31,
2004, the results of its operations, the changes in its net assets, and its
financial highlights for the period from August 12, 2004 (commencement of
operations) to December 31, 2004, in conformity with U.S. generally accepted
accounting principles.

                                                               Ernst & Young LLP

            financial reporting of the Trust and (ii) were pre-approved by the
            Trust's audit committee.

     (e)(1) Audit Committee Pre-Approval Policies and Procedures

            The Trust's Audit Committee Charter states the following with
            respect to pre-approval procedures:

                  "Pre-Approval Requirements. Before the independent accountants
                  are engaged by the Trust to render audit or non-audit
                  services, either:

                        1.    The Audit Committee shall pre-approve all auditing
                              services and permissible non-audit services (e.g.,
                              tax services) provided to the Trust. The Audit
                              Committee may delegate to one or more of its
                              members the authority to grant pre-approvals. Any
                              decision of any member to whom authority is
                              delegated under this section shall be presented to
                              the full Audit Committee at its next regularly
                              scheduled meeting; or

                        2.    The engagement to render the auditing service or
                              permissible non-audit service is entered into
                              pursuant to pre-approval policies and procedures
                              established by the Audit Committee. Any such
                              policies and procedures must (1) be detailed as to
                              the particular service and (2) not involve any
                              delegation of the Audit Committee's
                              responsibilities to the investment adviser. The
                              Audit Committee must be informed of each service
                              entered into pursuant to the policies and
                              procedures. A copy of any such policies and
                              procedures shall be attached as an exhibit to the
                              Audit Committee Charter.

            De Minimis Exceptions to Pre-Approval Requirements. Pre-Approval for
            a service provided to the Trust other than audit, review or attest
            services is not required if: (1) the aggregate amount of all such
            non-audit services provided to the Trust constitutes not more than 5
            percent of the total amount of revenues paid by the Trust to the
            independent accountants during the fiscal year in which the
            non-audit services are provided; (2) such services were not



              recognized by the Trust at the time of the engagement to be
              non-audit services; and (3) such services are promptly brought to
              the attention of the Audit Committee and are approved by the Audit
              Committee or by one or more members of the Audit Committee to whom
              authority to grant such approvals has been delegated by the Audit
              Committee prior to the completion of the audit.

              Pre-Approval of Non-Audit Services Provided to the Adviser and
              Certain Control Persons. The Audit Committee shall pre-approve any
              non-audit services proposed to be provided by the independent
              accountants to (a) the investment adviser and (b) any entity
              controlling, controlled by, or under common control with the
              investment adviser that provides ongoing services to the Trust, if
              the independent accountants' engagement with the investment
              adviser or any such control persons relates directly to the
              operations and financial reporting of the Trust. It shall be the
              responsibility of the independent accountants to notify the Audit
              Committee of any non-audit services that need to be pre-approved.

              Application of De Minimis Exception: The De Minimis exception set
              forth above applies to pre-approvals under this Section as well,
              except that the "total amount of revenues" calculation is based on
              the total amount of revenues paid to the independent accountants
              by the Trust and any other entity that has its services approved
              under this Section (i.e., the investment adviser or any control
              person)."

     (e)(2) Percentages of Services

            None of the services described in paragraphs (b) through (d) of this
            Item were performed in reliance on paragraph (c)(7)(i)(C) of Rule
            2-01 of Regulation S-X during the period of time for which such rule
            was effective.

     (f)    Not applicable.

     (g)    Total Fees Paid By Adviser and Certain Affiliates

            For the fiscal years ended December 31, 2004 and December 31, 2003,
            the aggregate non-audit fees billed by E&Y for services rendered to
            the Trust and the Adviser and any entity controlling, controlled by,
            or under common control with the Adviser that provided ongoing
            services to the Trust were $4,132,210 and $4,730,732, respectively.

     (h)    E&Y notified the Trust's Audit Committee of all non-audit services
            that were rendered by E&Y to the Adviser and any entity controlling,
            controlled by, or under common control with the Adviser that
            provides services to the Trust, which services were not required to
            be pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of
            Regulation S-X, allowing the Trust's Audit Committee to consider
            whether such services were compatible with maintaining E&Y's
            independence.
