EXPENSE EXAMPLE (UNAUDITED)

As a shareholder of the below listed Portfolios, 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 Portfolios 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 January 1, 2009 to June 30,
2009.

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.

*    The calculations are based on expenses incurred in the most recent six
     month period of the Portfolios. Each Portfolio's annualized average
     weighted expense ratio as of June 30, 2009 was as follows:


                                      
Money Market Portfolio                   0.11%

U.S. Government Money Market Portfolio   0.12%
Treasury Money Market Portfolio          0.12%
Treasury Plus Money Market Portfolio     0.13%


     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.

2. SIGNIFICANT ACCOUNTING POLICIES

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

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

The Portfolios adopted Financial Accounting Standards Board ("FASB") Statement
of Financial Accounting Standards No. 157, Fair Value Measurements ("FAS 157"),
effective for financial statements issued for fiscal years beginning after
November 15, 2007 and interim periods within those fiscal years. In accordance
with FAS 157, fair value is defined as the price that the portfolio would
receive upon selling an investment in a timely transaction to an independent
buyer in the principal or most advantageous market of the investment. Various
inputs are used in determining the value of the Portfolio's investments. FAS 157
established a three tier hierarchy of inputs to establish a classification of
fair value measurements and disclosure. The three tier hierarchy of inputs is
summarized below:

     -    Level 1 -- quoted prices in active markets for identical securities

     -    Level 2 -- other significant observable inputs (including quoted
          prices for similar securities, interest rates, prepayment speeds,
          credit risk, etc.)

     -    Level 3 -- significant unobservable inputs (including the Portfolio's
          own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not an indication of
the risk associated with investing in those securities.

The following is a summary of the inputs used, as of June 30, 2009, in valuing
the Portfolios' assets carried at fair value:



                                                                    INVESTMENTS IN

In April 2009, the FASB issued FASB Staff Position No. 157-4, "Determining Fair
Value When the Volume and Level of Activity for the Asset or Liability Have
Significantly Decreased and Identifying Transactions That Are Not Orderly" ("FSP
157-4"). FSP 157-4 provides additional guidance for estimating fair value in
accordance with FAS 157 when the volume and level of activity for the asset or
liability have significantly decreased as well as guidance on identifying
circumstances that indicate a transaction is not orderly. The type of inputs
used to value each security is identified in the Portfolio of Investments, which
also includes a breakdown of the Portfolios' investments by category.

On March 19, 2008, FASB released Statement of Financial Accounting Standards No.
161, "Disclosures about Derivative Instruments and Hedging Activities" ("FAS
161"). FAS 161 requires qualitative disclosures about objectives and strategies
for using derivatives, quantitative disclosures about fair value amounts of
gains and losses on derivative instruments, and disclosures about credit-risk
related contingent features in derivative agreements. The application of FAS 161
is required for fiscal years beginning after November 15, 2008 and interim
periods within those fiscal years. Management has evaluated the implication of
FAS 161 and there is no impact on the Portfolios' Financial Statements.

In September 2008, FASB issued a FASB Staff Position No. 133-1 and FIN 45-4
"Disclosures about Credit Derivatives and Certain Guarantees: An Amendment of
FASB Statement No. 133 and FASB Interpretation No. 45; and Clarification of the
Effective Date of FASB Statement No. 161" ("FSP 133"). FSP 133 requires enhanced
transparency of the effect of credit derivatives and guarantees on an issuer's
financial position, financial performance and cash flows. FSP 133 is effective
for fiscal years ending after November 15, 2007. FSP 133 applies to certain
credit derivatives, hybrid instruments that have embedded credit derivatives
(for example, credit-linked notes), and certain guarantees and it requires
additional disclosures regarding credit derivatives with sold protection.
Management has evaluated the implication of FSP 133 and there is no impact to
the Portfolios.

SECURITIES TRANSACTIONS, INVESTMENT INCOME AND EXPENSES - Securities
transactions are recorded on a trade date basis for financial statement
purposes. Interest income is recorded daily on the accrual basis


                                       34

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 Portfolios are allocated pro rata among the partners in the
Portfolios based on each partner's daily ownership percentage.

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

The Portfolios have reviewed the tax positions for open years as of December 31,
2008, and determined they did not have a liability for any unrecognized tax
expenses. The Portfolios recognize interest and penalties, if any, related to
tax liabilities as income tax expense in the Statement of Operations. As of June
30, 2009, tax years 2005 (or since inception, for Portfolios formed subsequent
to 2005) through 2008 remain subject to examination by the Portfolios' major tax
jurisdictions, which include the United States of America and the Commonwealth
of Massachusetts.

At June 30, 2009, 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 a Portfolio to repurchase the securities at a
mutually agreed upon price and time which, in the case of the Portfolios'
transactions, is generally within seven days. The total amount received by a
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 a 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. In addition, the proceeds of any such disposition
may be less than the amount the Portfolio is owed under the repurchase
agreement. A 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" or the "Adviser"),
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.
Expenses directly attributable to a Portfolio are charged to that Portfolio.
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 Portfolios' financial statements are prepared in
accordance with U.S. generally accepted accounting principles, which require the
use of management estimates. Actual results could differ from those estimates.

                               SEMI-ANNUAL REPORT

                                  JUNE 30, 2009
                                   (UNAUDITED)



STATE STREET EQUITY 500 INDEX PORTFOLIO

EXPENSE EXAMPLE (UNAUDITED)

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 January 1, 2009 to June 30,
2009.

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 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.

STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2009 (UNAUDITED)

1. ORGANIZATION

State Street Master Funds (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company, and was organized as a business trust under the laws of The
Commonwealth of Massachusetts on July 27, 1999. The Trust comprises eleven
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 Aggregate Bond Index Portfolio, the State Street Money Market
Portfolio, the State Street Tax Free Money Market Portfolio, the State Street
Short-Term Tax Exempt Bond Portfolio, the State Street Limited Duration Bond
Portfolio, the State Street Treasury Money Market Portfolio, the State Street
Treasury Plus 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 June
30, 2009, only the Portfolio, the State Street Money Market Portfolio, the State
Street Tax Free Money Market Portfolio, the State Street Short-Term Tax Exempt
Bond Portfolio, the State Street Treasury Money Market Portfolio, the State
Street Treasury Plus Money Market Portfolio and the State Street U.S. Government
Money Market Portfolio were in operation. The Portfolio is authorized to 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.
There is no assurance that the Portfolio will achieve its objective.

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.

The Portfolio adopted Financial Accounting Standards Board ("FASB") Statement of
Financial Accounting Standards No. 157, Fair Value Measurements ("FAS 157"),
effective for financial statements issued for fiscal years beginning after
November 15, 2007 and interim periods within those fiscal years. In accordance
with FAS 157, fair value is defined as the price that the portfolio would
receive upon selling an investment in a timely transaction to an independent
buyer in the principal or most advantageous market of the investment. Various
inputs are used in determining the value of the Portfolio's investments. FAS 157
established a three tier hierarchy of inputs to establish a

STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

classification of fair value measurements and disclosure. The three tier
hierarchy of inputs is summarized below:

     -    Level 1 -- quoted prices in active markets for identical securities

     -    Level 2 -- other significant observable inputs (including quoted
          prices for similar securities, interest rates, prepayment speeds,
          credit risk, etc.)

     -    Level 3 -- significant unobservable inputs (including the Portfolio's
          own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not an indication of
the risk associated with investing in those securities.

The following is a summary of the inputs used, as of June 30, 2009, in valuing
the Portfolio's assets carried at fair value:

In April 2009, the FASB issued FASB Staff Position No. 157-4, "Determining Fair
Value When the Volume and Level of Activity for the Asset or Liability Have
Significantly Decreased and Identifying Transactions That Are Not Orderly" ("FSP
157-4"). FSP 157-4 provides additional guidance for estimating fair value in
accordance with FAS 157 when the volume and level of activity for the asset or
liability have significantly decreased as well as guidance on identifying
circumstances that indicate a transaction is not orderly. The type of inputs
used to value each security is identified in the Portfolio of Investments, which
also includes a breakdown of the Portfolio's investments by category.

SECURITIES TRANSACTIONS, INVESTMENT INCOME AND EXPENSES: Securities transactions
are recorded on a trade date basis for financial statement purposes. 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.

The Portfolio has reviewed the tax positions for open years as of and during the
year ended December 31, 2008, and determined it did not have a liability for any
unrecognized tax expenses. The Portfolio recognizes interest and penalties, if
any, related to tax liabilities as income tax expense in the Statement of
Operations. As of June 30, 2009, tax years 2005 through 2008 remain subject to
examination by the Portfolio's major tax jurisdictions, which include the United
States of America and the Commonwealth of Massachusetts.

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 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.

The Portfolio adopted the provisions of FASB Statement of Financial Accounting
Standards No. 161 "Disclosures about Derivative Instruments and Hedging
Activities" ("FAS 161"). FAS 161 has established improved financial reporting
about derivative instruments and hedging activities as it relates to disclosure
associated with these types of investments. The following table, grouped into
appropriate risk categories, discloses the amounts related to the Funds use of
derivative instruments and hedging activities at June 30, 2009:

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

3. SECURITIES TRANSACTIONS

For the period ended June 30, 2009, purchases and sales of investment
securities, excluding short-term investments, futures contracts, and
contributions in-kind and fair value of withdrawals, aggregated to $202,423,545
and $66,166,854, respectively.

At June 30, 2009, the book cost of investments was $1,572,738,673 which
approximates cost computed on a federal tax basis. The aggregate gross
unrealized appreciation and gross unrealized depreciation was $393,534,625 and
$276,641,660, respectively, resulting in net appreciation of $116,892,965 for
all securities as computed on a federal income tax basis.

4. RELATED PARTY FEES AND TRANSACTIONS

The Portfolio has entered into an investment advisory agreement with SSgA Funds
Management, Inc. ("SSgA FM" or the "Adviser"), a subsidiary of State Street
Corporation and an affiliate of State Street Bank and Trust Company ("State
Street"), under which SSgA FM directs the investments of the Portfolio in
accordance with its investment objective, policies, and limitations. The Trust
has contracted with State Street to provide custody, administration and transfer
agent services to the Portfolio. In compensation for SSgA FM's services as
investment adviser and for State Street's services as administrator, custodian
and transfer agent (and for assuming ordinary operating expenses of the
Portfolio, including ordinary legal, audit and trustees expense), State Street
receives a unitary fee, calculated daily, at the annual rate of 0.045% of the
Portfolio's average daily net assets.

Certain investments made by the Portfolio were made in securities affiliated
with State Street and SSgA FM. Investments in State Street Corporation, the
holding company of State Street, were made according to its representative
portion of the S&P 500(R) Index. The market value of this investment at June 30,
2009 is listed in the Portfolio of Investments.

5. TRUSTEES' FEES

Pursuant to certain agreements with State Street and its affiliates, each
Independent Trustee receives for his or her services a $30,000 retainer in
addition to $2,500 for each in-person meeting and $500 for each telephonic
meeting from State Street or its affiliates.

6. INDEMNIFICATIONS

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 is
unknown as this could involve future claims against the Trust. Management does
not expect any significant claims.

7. SUBSEQUENT EVENTS

In accordance with the provisions set forth in FASB Statement of Financial
Accounting Standards No. 165 "Subsequent Events," adopted by the Portfolio as of
June 30, 2009, management has evaluated the possibility of subsequent events
existing in the Portfolio's financial statements through August 20, 2009.
Management has determined that there are no material events that would require
disclosure in the Portfolio's financial statements through this date.

STATE STREET INSTITUTIONAL SHORT-TERM TAX EXEMPT BOND PORTFOLIO

EXPENSE EXAMPLE (UNAUDITED)

As a shareholder of the State Street Short-Term Tax Exempt Bond 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 January 1, 2009 to June 30,
2009.

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.

Based on Hypothetical (5% return before expenses)      $1,000.00        $1,024.30         $0.50


*    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 June 30, 2009 was 0.10%. 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.

1. ORGANIZATION

The State Street Master Funds (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company, and was organized as a business trust under the laws of The
Commonwealth of Massachusetts on July 27, 1999. The Trust comprises eleven
investment portfolios: the State Street Equity 500 Index Portfolio, the State

the State Street Aggregate Bond Index Portfolio, the State Street Money Market
Portfolio, the State Street Tax Free Money Market Portfolio, the State Street
Short-Term Tax Exempt Bond Portfolio, the State Street Limited Duration Bond
Portfolio, the State Street Treasury Money Market Portfolio, the State Street
Treasury Plus 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 Short-Term Tax Exempt Bond Portfolio (the "Portfolio").
The Portfolio commenced operations on February 7, 2007. At June 30, 2009, only
the Portfolio, the State Street Equity 500 Index Portfolio, the State Street
Money Market Portfolio, the State Street Tax Free Money Market Portfolio, the
State Street Treasury Money Market Portfolio, the State Street Treasury Plus
Portfolio and the State Street U.S. Government Money Market Portfolio were in
operation. The Portfolio is authorized to issue an unlimited number of
non-transferable beneficial interests.

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. Fixed-income securities are valued on the basis of
the closing bid price. Investments in other mutual funds are valued at the net
asset value per share. 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.

The Portfolio adopted Financial Accounting Standards Board Statement of
Financial Accounting Standards No. 157, Fair Value Measurements ("FAS 157"),
effective for financial statements issued for fiscal years beginning after
November 15, 2007 and interim periods within those fiscal years. In accordance
with FAS 157, fair value is defined as the price that the portfolio would
receive upon selling an investment in a timely transaction to an independent
buyer in the principal or most advantageous market of the investment. Various
inputs are used in determining the value of the Portfolio's investments. FAS 157
established a three tier hierarchy of inputs to establish a classification of
fair value measurements and disclosure. The three tier hierarchy of inputs is
summarized below:

     -    Level 1 -- quoted prices in active markets for identical securities

     -    Level 2 -- other significant observable inputs (including quoted
          prices for similar securities, interest rates, prepayment speeds,
          credit risk, etc.)

     -    Level 3 -- significant unobservable inputs (including the Portfolio's
          own assumptions in determining the fair value of investments)

In April 2009, the FASB issued FASB Staff Position No. 157-4, "Determining Fair
Value When the Volume and Level of Activity for the Asset or Liability Have
Significantly Decreased and Identifying Transactions That Are Not Orderly" ("FSP
157-4"). FSP 157-4 provides additional guidance for estimating fair value in
accordance with FAS 157 when the volume and level of activity for the asset or
liability have significantly decreased as well as guidance on identifying
circumstances that indicate a transaction is not orderly. The type of inputs
used to value each security is identified in the Portfolio of Investments, which
also includes a breakdown of the Portfolio's investments by category.

On March 19, 2008, the FASB released Statement of Financial Accounting Standards
No. 161, "Disclosures about Derivative Instruments and Hedging Activities" ("FAS
161"). FAS 161 requires qualitative disclosures about objectives and strategies
for using derivatives, quantitative disclosures about fair value amounts of
gains and losses on derivative instruments, and disclosures about credit-risk
related contingent features in derivative agreements. The application of FAS 161
is required for fiscal years beginning after November 15, 2008 and interim
periods within those fiscal years. Management has evaluated the implication of
FAS 161 and there is no impact on the Portfolio's Financial Statements.

In September 2008, FASB issued a FASB Staff Position No. 133-1 and FIN 45-4
"Disclosures about Credit Derivatives and Certain Guarantees: An Amendment of
FASB Statement No. 133 and FASB Interpretation No. 45; and Clarification of the
Effective Date of FASB Statement No. 161" ("FSP 133"). FSP 133 requires enhanced
transparency of the effect of credit derivatives and guarantees on an issuer's
financial position, financial performance and cash flows. FSP 133 is effective
for fiscal years ending after November 15, 2007. FSP 133 applies to certain
credit derivatives, hybrid instruments that have embedded credit derivatives
(for example, credit-linked notes), and certain guarantees and it requires
additional disclosures regarding credit derivatives with sold protection.
Management has evaluated the implication of FSP 133 and there is no impact to
the Portfolio.

SECURITIES TRANSACTIONS, INVESTMENT INCOME AND EXPENSES - Securities
transactions are recorded on a trade date basis for financial statement
purposes. 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.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
JUNE 30, 2009 (UNAUDITED)

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.

The Portfolio has reviewed the tax positions for open years as of December 31,
2008, and determined it did not have a liability for any unrecognized tax
expenses. The Portfolio recognizes interest and penalties, if any, related to
tax liabilities as income tax expense in the Statement of Operations. As of June
30, 2009, tax years since inception through 2008 remain subject to examination
by the Portfolio's major tax jurisdictions, which include the United States of
America and the Commonwealth of Massachusetts.

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

3. SECURITIES TRANSACTIONS

For the six months ended June 30, 2009, purchases and sales of investment
securities, excluding short-term investments, futures contracts, and in-kind
contributions and withdrawals, aggregated to $18,835,793 and $27,308,817,
respectively.

At June 30, 2009, the book cost of investments was $83,619,185 which
approximates cost computed on a federal tax basis. The aggregate gross
unrealized appreciation and gross unrealized depreciation was $1,063,896 and
$55,543, respectively, resulting in net appreciation of $1,008,353 for all
securities as computed on a federal income tax basis.

4. RELATED PARTY FEES

The Portfolio has entered into an investment advisory agreement with SSgA Funds
Management, Inc. ("SSgA FM" or the "Adviser"), a subsidiary of State Street
Corporation and an affiliate of State Street Bank and Trust Company ("State
Street"). 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
contractually agreed to cap the total operating expenses of the Portfolio at
0.10% of the Portfolio's average daily net assets through April 30, 2009. For
the six months ended June 30, 2009, the Adviser reimbursed the Portfolio $46,650
under this agreement.

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 Trust pays State Street an annual fee,

Thereafter                                           0.01%
Minimum annual fee for the trust:                $150,000


5. 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 $30,000. Each trustee is reimbursed for out-of-pocket and
travel expenses.

6. INDEMNIFICATIONS

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 is
unknown as this could involve future claims against the Trust. Management does
not expect any significant claims.

7. SUBSEQUENT EVENTS

In accordance with the provisions set forth in FASB Statement of Financial
Accounting Standards No. 165 "Subsequent Events," adopted by the Portfolio as of
June 30, 2009, management has evaluated the possibility of subsequent events
existing in the Portfolio's financial statements through August 20, 2009.
Management has determined that there are no material events that would require
disclosure in the Portfolio's financial statements through this date.
