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.

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 Limited Duration Bond Portfolio, the State Street Short-Term Tax Exempt Bond Portfolio, the State Street U.S. Government Money Market Portfolio, the State Street Treasury Money Market Portfolio and the State Street Treasury Plus Money Market Portfolio. At June 30, 2010, the following Portfolios were in operation: the State Street Equity 500 Index Portfolio, the State Street Money Market Portfolio, the State Street Tax Free Money Market Portfolio, the State Street Short-Term Tax Free Bond Portfolio, the State Street U.S. Government Money Market Portfolio, the State Street Treasury Money Market Portfolio and the State Street Treasury Plus Money Market Portfolio. Information presented in these financial statements pertains only to the State Street Money Market Portfolio, the State Street Tax Free Money Market Portfolio, the State Street U.S. Government Money Market Portfolio, the State Street Treasury Money Market Portfolio and the State Street Treasury Plus Money Market Portfolio (the "Portfolios"). The Portfolios commenced operations as follows: <Table> <Caption> - ----------------------------------------------------------------------------------- PORTFOLIO NAME COMMENCEMENT DATE - ----------------------------------------------------------------------------------- State Street Money Market Portfolio August 12, 2004 - ----------------------------------------------------------------------------------- State Street Tax Free Money Market Portfolio February 7, 2007 - ----------------------------------------------------------------------------------- State Street U.S. Government Money Market Portfolio October 17, 2007 - ----------------------------------------------------------------------------------- State Street Treasury Money Market Portfolio October 25, 2007 - ----------------------------------------------------------------------------------- State Street Treasury Plus Money Market Portfolio October 24, 2007 - ----------------------------------------------------------------------------------- </Table> The Portfolios are authorized to issue an unlimited number of non-transferable beneficial interests. 55 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2010 (UNAUDITED) The Portfolios' investment objectives are as follows: <Table> <Caption> - ---------------------------------------------------------------------------------- PORTFOLIO NAME INVESTMENT OBJECTIVE - ---------------------------------------------------------------------------------- State Street Money Market Portfolio To seek to maximize current income, to the extent consistent with the preservation of capital and liquidity by investing in dollar denominated securities. - ---------------------------------------------------------------------------------- State Street Tax Free Money Market To seek to maximize current income, Portfolio exempt from federal income taxes, to the extent consistent with the preservation of capital and liquidity. - ---------------------------------------------------------------------------------- State Street U.S. Government Money To seek to maximize current income, to Market Portfolio the extent consistent with the preservation of capital and liquidity by investing in U.S. government securities and in repurchase agreements collateralized by U.S. government securities. - ---------------------------------------------------------------------------------- State Street Treasury Money Market To seek a high level of current income Portfolio consistent with preserving principal and liquidity. - ---------------------------------------------------------------------------------- State Street Treasury Plus Money Market To seek a high level of current income Portfolio consistent with preserving principal and liquidity by investing in a portfolio consisting principally of U.S. Treasury securities and repurchase agreements collateralized by such securities. - ---------------------------------------------------------------------------------- </Table> 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.) 56 STATE STREET MASTER FUNDS 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> <Caption> - ---------------------------------------------------------------------------------------------------------------------------------- INVESTMENTS IN SECURITIES --------------------------------------------------------------------------------------------------- STATE STREET TAX STATE STREET U.S. STATE STREET STATE STREET STATE STREET MONEY FREE MONEY GOVERNMENT MONEY TREASURY MONEY TREASURY PLUS MONEY VALUATION INPUTS MARKET PORTFOLIO MARKET PORTFOLIO MARKET PORTFOLIO MARKET PORTFOLIO MARKET PORTFOLIO - ---------------------------------------------------------------------------------------------------------------------------------- Level 1 -- Quoted Prices $ - $ 31,790,318 $ - $ - $ - - ---------------------------------------------------------------------------------------------------------------------------------- Level 2 -- Other Significant Observable Inputs 19,166,949,697 360,859,000 4,577,755,140 3,261,963,477 1,017,280,543 - ---------------------------------------------------------------------------------------------------------------------------------- Level 3 -- Significant Unobservable Inputs - - - - - - ---------------------------------------------------------------------------------------------------------------------------------- Total Investments $19,166,949,697 $392,649,318 $4,577,755,140 $3,261,963,477 $1,017,280,543 - ---------------------------------------------------------------------------------------------------------------------------------- </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. 57 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 58 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2010 (UNAUDITED) described below, of the following annual percentages of the Trust's average aggregate daily net assets, exclusive of the Equity 500 Index Portfolio, during the month as follows: <Table> <Caption> ANNUAL PERCENTAGE OF ASSET LEVELS AVERAGE AGGREGATE DAILY NET ASSETS - ------------ ----------------------------------- First $400 million 0.03% Next $15 billion 0.02% Thereafter 0.01% Minimum annual fee per Portfolio $150,000 </Table> 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. 59 STATE STREET MASTER FUNDS GENERAL INFORMATION (UNAUDITED) JUNE 30, 2010 PROXY VOTING POLICIES AND PROCEDURES AND RECORD The Trust has adopted proxy voting procedures relating to portfolio securities held by the Portfolios.

Box 5049 Boston, MA 02206 STATE STREET EQUITY 500 INDEX PORTFOLIO SEMI-ANNUAL REPORT JUNE 30, 2010 (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, 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. Six Months Ended June 30, 2010 <Table> <Caption> - ----------------------------------------------------------------------------------------- BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING JANUARY 1, 2010 JUNE 30, 2010 PERIOD * - ----------------------------------------------------------------------------------------- Based on Actual Portfolio Return $1,000.00 $933.80 $0.22 - ----------------------------------------------------------------------------------------- Based on Hypothetical (5% return before expenses) $1,000.00 $1,024.57 $0.23 - ----------------------------------------------------------------------------------------- </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). 17 STATE STREET EQUITY 500 INDEX PORTFOLIO PORTFOLIO STATISTICS (UNAUDITED) <Table> PORTFOLIO COMPOSITION* JUNE 30, 2010 - -------------------------------------------------------------------------------- Common Stocks 97.4% - -------------------------------------------------------------------------------- Money Market Funds 2.1 - -------------------------------------------------------------------------------- U.S. Government Securities 0.4 - -------------------------------------------------------------------------------- Other Assets in Excess of Liabilities 0.1 - -------------------------------------------------------------------------------- TOTAL 100.0% - -------------------------------------------------------------------------------- </Table> <Table> TOP FIVE SECTORS (EXCLUDING SHORT-TERM INVESTMENTS) * JUNE 30, 2010 - -------------------------------------------------------------------------------- Information Technology 17.2% - -------------------------------------------------------------------------------- Financials 16.5 - -------------------------------------------------------------------------------- Health Care 11.6 - -------------------------------------------------------------------------------- Consumer Staples 11.2 - -------------------------------------------------------------------------------- Energy 10.5 - -------------------------------------------------------------------------------- TOTAL 67.0% - -------------------------------------------------------------------------------- </Table> * As a percentage of net assets as of the date indicated.

See Notes to Financial Statements. 28 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 29 STATE STREET EQUITY 500 INDEX PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2010 (UNAUDITED) 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> <Caption> QUOTED PRICES IN ACTIVE MARKETS FOR SIGNIFICANT OTHER SIGNIFICANT IDENTICAL ASSETS OBSERVABLE INPUTS UNOBSERVABLE INPUTS DESCRIPTION (LEVEL 1) (LEVEL 2) (LEVEL 3) TOTAL - ----------- ------------------ ----------------- ------------------- ---------- INVESTMENTS: Common Stocks $ 1,685,327 $ - $ - $1,685,327 U.S. Government Securities - 6,713 - 6,713 Money Market Funds 36,125 - - 36,125 OTHER LIABILITIES: Futures contracts (2,753) - - (2,753) ----------- ------ ------------ ---------- TOTAL ASSETS AND LIABILITIES $1,718,699 $6,713 $- $1,725,412 =========== ====== ============ ========== </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 31 STATE STREET EQUITY 500 INDEX PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2010 (UNAUDITED) categories, discloses the amounts related to the Portfolio's use of derivative instruments and hedging activities at June 30, 2010: LIABILITY DERIVATIVES(1) (AMOUNTS IN THOUSANDS) <Table> <Caption> FOREIGN INTEREST RATE EXCHANGE CREDIT EQUITY COMMODITY OTHER CONTRACTS RISK CONTRACTS RISK CONTRACTS RISK CONTRACTS RISK CONTRACTS RISK CONTRACTS RISK TOTAL -------------- -------------- -------------- -------------- -------------- -------------- ------- Futures Contracts $ - $ - $ - $(2,753) $ - $ - $(2,753) </Table> (1) Portfolio of Investments: Unrealized depreciation of futures contracts.

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 32 STATE STREET EQUITY 500 INDEX PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2010 (UNAUDITED) 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. 33 STATE STREET EQUITY 500 INDEX PORTFOLIO GENERAL INFORMATION JUNE 30, 2010 (UNAUDITED) PROXY VOTING POLICIES AND PROCEDURES AND RECORD The Trust has adopted proxy voting procedures relating to portfolio securities held by the Portfolio.

Box 5049 Boston, MA 02206 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO SEMI-ANNUAL REPORT JUNE 30, 2010 (UNAUDITED) 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.

See Notes to Financial Statements. 24 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 25 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2010 (UNAUDITED) 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: <Table> <Caption> QUOTED PRICES IN ACTIVE MARKETS FOR SIGNIFICANT OTHER SIGNIFICANT IDENTICAL ASSETS OBSERVABLE INPUTS UNOBSERVABLE INPUTS DESCRIPTION (LEVEL 1) (LEVEL 2) (LEVEL 3) TOTAL - ----------- ------------------ ----------------- ------------------- ----------- TAX-EXEMPT OBLIGATIONS... $ - $83,779,330 $- $83,779,330 ---------- ----------- ------------ ----------- MONEY MARKET FUND........ 3,886,162 - - 3,886,162 ---------- ----------- ------------ ----------- TOTAL INVESTMENTS........ $3,886,162 $83,779,330 $ - $87,665,492 ========== =========== ============ =========== </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. 26 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2010 (UNAUDITED) 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.
