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.

See Notes to Financial Statements. 31 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS JUNE 30, 2009 (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 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, 2009, only 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 were in operation. 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: 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 The Portfolios are authorized to issue an unlimited number of non-transferable beneficial interests. 32 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2009 (UNAUDITED) The Portfolios' investment objectives are as follows: 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 Portfolio To seek to maximize current income, exempt from federal income taxes, to the extent consistent with the preservation of capital and liquidity. State Street U.S. Government Money Market Portfolio To seek to maximize current income, to the extent consistent with the preservation of capital and liquidity by investing in U.S. government securities with remaining maturities of one year or less and in repurchase agreements collateralized by U.S. government securities. State Street Treasury Money Market Portfolio To seek a high level of current income consistent with preserving principal and liquidity. State Street Treasury Plus Money Market Portfolio To seek a high level of current income consistent with preserving principal and liquidity by investing in a portfolio made up principally of U.S. Treasury securities and repurchase agreements collateralized by such securities. 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) 33 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2009 (UNAUDITED) 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 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 $ -- $ 53,256,559 $ -- $ -- $ -- Level 2 -- Other Significant Observable Inputs 9,619,556,522 424,934,163 2,908,351,499 3,294,406,877 359,434,946 Level 3 -- Significant Unobservable Inputs -- -- -- -- -- Total $9,619,556,522 $478,190,722 $2,908,351,499 $3,294,406,877 $359,434,946 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 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2009 (UNAUDITED) 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. 35 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2009 (UNAUDITED) 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. The Adviser contractually agreed to cap the total operating expenses of the State Street Money Market Portfolio and the State Street Tax Free Money Market Portfolio at 0.10% of the respective Portfolio's average daily net assets through April 30, 2009. For the period ended June 30, 2009, SSgA FM reimbursed the Portfolios under this agreement as follows: FUND AMOUNT - ---- -------- State Street Money Market Portfolio $589,262 State Street Tax Free Money Market Portfolio 51,980 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 at and payable monthly at the applicable fee rate described below, of the following annual percentages of the Trust's average aggregate daily net assets during the month as follows: ANNUAL PERCENTAGE OF ASSET LEVELS AVERAGE AGGREGATE DAILY NET ASSETS - ------------ ----------------------------------- First $400 Million 0.03% Thereafter 0.02 Minimum annual fee for the trust: $150,000 Effective August 1, 2009, the annual fees paid by the Trust to State Street for its services as administrator, custodian, and transfer agent for the Portfolios were revised as follows: 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 for the trust: $150,000 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 36 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2009 (UNAUDITED) 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 the provisions set forth in FASB Statement of Financial Accounting Standards No. 165 "Subsequent Events," adopted by the Portfolios as of June 30, 2009, management has evaluated the possibility of subsequent events existing in the Portfolios' financial statements through August 20, 2009. Management has determined that there are no material events that would require disclosure in the Portfolios' financial statements through this date. 37 STATE STREET MASTER FUNDS GENERAL INFORMATION (UNAUDITED) JUNE 30, 2009 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, 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. Six Months Ended June 30, 2009 BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING JANUARY 1, 2009 JUNE 30, 2009 PERIOD* --------------- ------------- ------------- Based on Actual Portfolio Return $1,000.00 $1,032.00 $0.23 Based on Hypothetical (5% return before expenses) $1,000.00 $1,024.57 $0.23 * 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, 2009 was 0.045%. The dollar amounts shown as "Expenses Paid" are equal to the annualized average weighted expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six month period, then divided by the number of days in the most recent 12 month period. 2 STATE STREET EQUITY 500 INDEX PORTFOLIO PORTFOLIO STATISTICS (UNAUDITED) PORTFOLIO COMPOSITION* JUNE 30, 2009 - ---------------------- ------------- Common Stocks 97.6% Money Market Funds 2.3 U.S. Government Securities 0.3 Liabilities in Excess of Assets (0.2) ----- TOTAL 100.0% ===== TOP FIVE SECTORS (EXCLUDING SHORT-TERM INVESTMENTS)* JUNE 30, 2009 - ---------------------------------------------------- ------------- Information Technology 17.3% Financials 13.6 Health Care 13.3 Energy 12.2 Consumer Staples 11.7 ---- TOTAL 68.1% ==== * As a percentage of net assets as of the date indicated.

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 17 STATE STREET EQUITY 500 INDEX PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2009 (UNAUDITED) 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: QUOTED PRICES IN ACTIVE SIGNIFICANT MARKETS FOR OTHER SIGNIFICANT IDENTICAL OBSERVABLE UNOBSERVABLE ASSETS INPUTS INPUTS DESCRIPTION (LEVEL 1) (LEVEL 2) (LEVEL 3) TOTAL - ----------- ----------- ----------- ------------ ---------- ASSETS: COMMON STOCKS $1,645,414 $ -- $-- $1,645,414 U.S. GOVERNMENT SECURITIES -- 4,813 -- 4,813 MONEY MARKET FUNDS 39,405 -- -- 39,405 ---------- ------- --- ---------- TOTAL INVESTMENTS 1,684,819 4,813 -- 1,689,632 LIABILITIES: INVESTMENTS IN OTHER FINANCIAL INSTRUMENTS Futures contracts (1,165) (1,165) ---------- ---------- TOTAL INVESTMENTS IN OTHER FINANCIAL INSTRUMENTS (1,165) -- -- (1,165) ---------- ------- --- ---------- TOTAL $1,683,654 $ 4,813 $-- $1,688,467 ========== ======= === ========== 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. 18 STATE STREET EQUITY 500 INDEX PORTFOLIO 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 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.

Box 5049 Boston, MA 02206 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO SEMI-ANNUAL REPORT JUNE 30, 2009 (UNAUDITED) 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. Six Months Ended June 30, 2009 BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING JANUARY 1, 2009 JUNE 30, 2009 PERIOD * --------------- ------------- ------------- Based on Actual Portfolio Return $1,000.00 $1,018.20 $0.50 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. 2 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO PORTFOLIO STATISTICS (UNAUDITED) PORTFOLIO COMPOSITION* JUNE 30, 2009 - ---------------------- ------------- General Obligations 36.03% Miscellaneous Revenue 16.29 Pre Refunded/Escrow to Maturity 11.30 General Obligation State 9.62 Hospital 6.25 Higher Education 4.80 Lease 4.52 Transportation Revenue 3.41 Cash 2.57 Water Revenue 1.42 Industrial Development Revenue/Pollution Control Revenue 1.26 Water & Sewer 1.20 Special Tax Revenue 0.72 Sales Tax Revenue 0.61 ------ TOTAL 100.00% ====== MATURITY LADDER* JUNE 30, 2009 - ---------------- ------------- Less than 1 year 23.60% 1-2 years 55.67 2-3 years 20.73 ------ TOTAL 100.00% ====== * The Portfolio's composition will vary over time.

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, 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) 13 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2009 (UNAUDITED) 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: 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 ... $ -- $82,424,278 $-- $82,424,278 ---------- ----------- --- ----------- MONEY MARKET FUND ........ 2,203,260 -- -- 2,203,260 ---------- ----------- --- ----------- TOTAL INVESTMENTS ........ $2,203,260 $82,424,278 $-- $84,627,538 ========== =========== === =========== 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. 14 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO 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, 15 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) JUNE 30, 2009 (UNAUDITED) which is accrued daily at the applicable fee rate described below and payable monthly, of the following annual percentages of the Trust's average aggregate daily net assets during the month as follows: ANNUAL PERCENTAGE OF ASSET LEVELS AVERAGE AGGREGATE DAILY NET ASSETS - ------------ ---------------------------------- First $400 Million 0.03% Thereafter 0.02 Minimum annual fee for the trust: $150,000 Effective August 1, 2009, the annual fees paid by the Trust to State Street for its services as administrator, custodian, and transfer agent for the Portfolios were revised as follows: 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 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. 16 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO GENERAL INFORMATION (UNAUDITED) JUNE 30, 2009 PROXY VOTING POLICIES AND PROCEDURES AND RECORD The Trust has adopted proxy voting procedures relating to portfolio securities held by the Portfolio.
