EXPENSE EXAMPLE (UNAUDITED)

As a shareholder of the below listed portfolios (the "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, 2010 to June 30,
2010.

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, 2010 was as follows:

  <Table>

  average weighted expense ratio multiplied by the average account value over
  the period, multiplied by 181/365 (the most recent six 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 provisions surrounding Fair Value Measurements and
Disclosures that define fair value, establish a framework for measuring fair
value in generally accepted accounting principles and expand disclosures about
fair value measurements. This applies to fair value measurements that are
already required or permitted by other accounting standards and is intended to
increase consistency of those measurements and applies broadly to securities and
other types of assets and liabilities. In accordance with these provisions, fair
value is defined as the price that a 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 Portfolios' investments.

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.)

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
JUNE 30, 2010 (UNAUDITED)

     - Level 3 -- significant unobservable inputs (including a 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, 2010, in valuing
the Portfolios' assets carried at fair value:

</Table>


The type of inputs used to value each security under the provisions surrounding
Fair Value Measurement and Disclosures is identified in each Portfolio of
Investments, which also includes a breakdown of the Portfolios' investments by
category.

The Portfolios adopted updated provisions surrounding Fair Value Measurements
and Disclosures effective March 31, 2010. This update applies to the Portfolios'
disclosures about transfers in and out of Level 1 and Level 2 of the fair value
hierarchy and the reasons for the transfers as well as disclosures about the
valuation techniques and inputs used to measure fair value for investments that
fall in either Level 2 or Level 3 fair value hierarchy.

As of the period ended June 30, 2010, there were no securities transferred from
Level 1 to Level 2 and no securities transferred from Level 2 to Level 1.

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.

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.

STATE STREET MASTER FUNDS
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
JUNE 30, 2010 (UNAUDITED)

The Portfolios have reviewed the tax positions for open years as of December 31,
2009, 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, 2010, tax years 2006 (or since inception, for Portfolios formed subsequent
to 2006) through 2009 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, 2010, the cost of investments for federal income tax purposes was
substantially 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) a 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 a 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.

3.  RELATED PARTY FEES
The Portfolios have entered into investment advisory agreements with the
Adviser. The Adviser directs the investments of the Portfolios in accordance
with their investment objectives, policies, and limitations. In compensation for
the Adviser's services as investment adviser, each Portfolio pays the Adviser an
annual fee of 0.10% of the respective Portfolio's average daily net assets.

State Street is the administrator, custodian and transfer agent for the
Portfolios. In compensation for State Street's services as administrator,
custodian and transfer agent beginning February 1, 2007, the Trust pays State
Street an annual fee, which is accrued daily and payable monthly at the
applicable fee rate

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

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

6.  SUBSEQUENT EVENTS
In accordance with provisions surrounding Subsequent Events adopted by the
Portfolios, management has evaluated the possibility of subsequent events
existing in the Portfolios' financial statements. Management has determined that
there are no material events that would require disclosure in the Portfolios'
financial statements.

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, 2010 to June 30,
2010.

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.

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



  * The calculations are based on expenses incurred in the most recent fiscal
    period of the Portfolio. The annualized average weighted expense ratio as
    of June 30, 2010 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 181/365 (the most
    recent six month period).

STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2010 (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, 2010, the following Portfolios were in operation: 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. 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 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 provisions surrounding Fair Value Measurements and
Disclosures that defines fair value, establishes a framework for measuring fair
value in generally accepted accounting principles and expands disclosures about
fair value measurements. This applies to fair value measurements that are
already required or permitted by other accounting standards and is intended to
increase consistency of those measurements and applies broadly to securities and
other types of assets and liabilities. In accordance with these provisions, 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.

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, 2010, in valuing
the Portfolio's assets carried at fair value (amounts in thousands):

</Table>


The type of inputs used to value each security under the provisions surrounding
Fair Value Measurement and Disclosures is identified in the Portfolio of
Investments, which also includes a breakdown of the Portfolio's investments by
category.

The Portfolio adopted updated provisions surrounding Fair Value Measurements and
Disclosures effective March 31, 2010. This update applies to the Portfolio's
disclosures about transfers in and out of Level 1 and Level 2 of the fair value
hierarchy and the reasons for the transfers as well as disclosures about the
valuation techniques and inputs used to measure fair value for investments that
fall in either Level 2 or Level 3 fair value hierarchy.

As of the period ended June 30, 2010, there were no securities transferred from
Level 1 to Level 2 and no securities transferred from Level 2 to Level 1.

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

                                       30



STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
JUNE 30, 2010 (UNAUDITED)


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, 2009, 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, 2010, tax years 2006 through 2009 remain subject to
examination by the Portfolio's major tax jurisdictions, which include the United
States of America and the Commonwealth of Massachusetts.

At June 30, 2010, the book cost of investments was $1,372,215 which approximates
cost computed on a federal tax basis. The aggregate gross unrealized
appreciation and gross unrealized depreciation was $488,044 and $132,094,
respectively, resulting in net appreciation of $355,950 for all securities as
computed on a federal income tax basis.

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 provisions surrounding Derivatives and Hedging which
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 following table, grouped into
appropriate risk

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, 2010, purchases and sales of investment
securities, excluding short-term investments, futures contracts, contributions
in-kind and fair value of withdrawals, aggregated to $169,814 and $190,169,
respectively.

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. For the period ended June 30, 2010, these
fees amounted to $415.

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, 2010 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. These fees are paid through a
unitary fee.

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 provisions surrounding Subsequent Events adopted by the
Portfolio, management has evaluated the possibility of subsequent events
existing in the Portfolio's financial statements. Management has determined that
there are no material events that would require disclosure in the Portfolio's
financial statements.

STATE STREET 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, 2010 to June 30,
2010.

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.

</Table>



  * 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, 2010 was 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
    181/365 (the most recent six month period).

STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2010 (UNAUDITED)

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
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 Short-Term Tax Exempt Bond Portfolio (the "Portfolio").
The Portfolio commenced operations on February 7, 2007. At June 30, 2010, the
following Portfolios were in operation: 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. The Portfolio is authorized to issue an
unlimited number of non-transferable beneficial interests.

The Short-Term Tax Exempt Bond Portfolio's investment objective is to seek to
provide federally tax-exempt current income and liquidity. The Portfolio invests
at least 80% of its assets in a diversified portfolio of investment grade
municipal debt securities and maintains a dollar-weighted average portfolio
duration of two years or less. The Portfolio is not a money market fund, and it
is expected that the Portfolio will be managed in such a way that a feeder
fund's net asset value per share will fluctuate. There is no assurance that the
Portfolio will achieve its investment objective, and you could lose money by
investing in the Portfolio.

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 provisions surrounding Fair Value Measurements and
Disclosures that defines fair value, establishes a framework for measuring fair
value in generally accepted accounting principles and expands disclosures about
fair value measurements. This applies to fair value measurements that are
already required or permitted by other accounting standards and is intended to
increase consistency of those measurements and applies broadly to securities and
other types of assets and liabilities. In accordance with these provisions, 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

     - 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, 2010, in valuing the Portfolio's
assets carried at fair value:

</Table>


The type of inputs used to value each security under the provisions surrounding
Fair Value Measurement and Disclosures is identified in the Portfolio of
Investments, which also includes a breakdown of the Portfolio's investments by
category.

The Portfolio adopted updated provisions surrounding Fair Value Measurements and
Disclosures effective March 31, 2010. This update applies to the Portfolio's
disclosures about transfers in and out of Level 1 and Level 2 of the fair value
hierarchy and the reasons for the transfers as well as disclosures about the
valuation techniques and inputs used to measure fair value for investments that
fall in either Level 2 or Level 3 fair value hierarchy.

As of the period ended June 30, 2010, there were no securities transferred from
Level 1 to Level 2 and no securities transferred from Level 2 to Level 1.

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.

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,
2009, 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, 2010, tax years since inception through 2009 remain subject to examination
by the Portfolio's major tax jurisdictions, which include the United States of
America and the Commonwealth of Massachusetts.

At June 30, 2010, the book cost of investments was $86,804,062 which
approximates cost computed on a federal tax basis. The aggregate gross
unrealized appreciation and gross unrealized depreciation was $867,537 and
$6,107, respectively, resulting in net appreciation of $861,430 for all
securities as computed on a federal income tax basis.

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, 2010, purchases and sales of investment
securities, excluding short-term investments and in-kind contributions and
withdrawals, aggregated to $24,433,310 and $11,736,806, respectively.

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 is responsible for the investment management 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 voluntarily agreed to cap the total operating
expenses of the Portfolio at 0.10% of the Portfolio's average daily net assets
for the period January 1, 2010 through April 13, 2010. For the period ended June
30, 2010, the Adviser reimbursed the Portfolio $21,664 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, which
is accrued daily and payable monthly at the applicable fee rate described below,

5. INVESTMENT SUB-ADVISER
Effective April 1, 2010, Nuveen Asset Management ("Nuveen") serves as the
investment sub-adviser to the Portfolio and is responsible for the day-to-day
management of the Portfolio's investments, subject to supervision by the Adviser
and the Board of Trustees. For its services, the Adviser pays Nuveen 50% of the
advisory fee paid by the Portfolio to the Adviser. The Portfolio is not
responsible for the fees  paid to Nuveen.

6. 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.

7. 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.

8. SUBSEQUENT EVENTS
In accordance with provisions surrounding Subsequent Events adopted by the
Portfolio, management has evaluated the possibility of subsequent events
existing in the Portfolio's financial statements. Management has determined that
there are no material events that would require disclosure in the Portfolio's
financial statements.
