STATE STREET MASTER FUNDS ANNUAL REPORT DECEMBER 31, 2008 STATE STREET MONEY MARKET PORTFOLIO STATE STREET TAX FREE MONEY MARKET PORTFOLIO STATE STREET U.S. GOVERNMENT MONEY MARKET PORTFOLIO STATE STREET TREASURY MONEY MARKET PORTFOLIO STATE STREET TREASURY PLUS MONEY MARKET PORTFOLIO STATE STREET MASTER FUNDS EXPENSE EXAMPLE As a shareholder of the below listed Portfolios, you incur ongoing costs, which include costs for portfolio management and administrative services, among others. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Portfolios and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period shown and held for the entire period from July 1, 2008 to December 31, 2008. 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.

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 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) STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2008 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 December 31, 2008, in valuing the Portfolio's 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 $ -- $ 98,799,778 $ -- $ -- $ -- Level 2 -- Other Significant Observable Inputs 8,597,336,889 288,031,357 2,959,323,030 2,745,961,938 953,331,995 Level 3 -- Significant Unobservable Inputs -- -- -- -- -- Total $8,597,336,889 $386,831,135 $2,959,323,030 $2,745,961,938 $953,331,995 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. The Portfolio has reviewed the tax positions for open years as of December 31, 2008, and determined the Portfolios 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 December 31, 2008, 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 State of America and the Commonwealth of Massachusetts. At December 31, 2008, 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 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2008 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 that 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 SSgA FM. 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 has 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 until April 30, 2009. For the year ended December 31, 2008, SSgA FM reimbursed the Portfolios under this agreement as follows: FUND AMOUNT - ---- ---------- State Street Money Market Portfolio $1,813,933 State Street Tax Free Money Market Portfolio 174,903 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 STATE STREET MASTER FUNDS NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2008 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 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. NEW ACCOUNTING PRONOUNCEMENTS 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 and 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. At this time, management is evaluating the implications of FAS 161 and believes the impact of adopting FAS 161 will be limited to additional disclosures. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees of State Street Master Funds: We have audited the accompanying statements of assets and liabilities of the State Street Money Market Portfolio, State Street Tax Free Money Market Portfolio, State Street U.S. Government Money Market Portfolio, State Street Treasury Money Market Portfolio, and State Street Treasury Plus Money Market Portfolio (five of the portfolios constituting State Street Master Funds) (the "Portfolios"), including the portfolios of investments, as of December 31, 2008, and the related statements of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Portfolios' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Portfolios' internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Portfolios' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2008, by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the State Street Money Market Portfolio, State Street Tax Free Money Market Portfolio, State Street U.S. Government Money Market Portfolio, State Street Treasury Money Market Portfolio, and State Street Treasury Plus Money Market Portfolio of State Street Master Funds at December 31, 2008, the results of their operations for the year then ended, and the changes in their net assets and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

ADVISORY AGREEMENT RENEWAL The Board of Trustees of the Trust met on November 20, 2008 (the "Meeting") to consider the approval of the investment advisory agreements (the "Advisory Agreements") for State Street Money Market Portfolio (the "Money Market Portfolio"), State Street Tax Free Money Market Portfolio (the "Tax Free Portfolio"), State Street U.S. Government Money Market Portfolio (the "U.S. Government Portfolio"), State Street Treasury Money Market Fund (the "Treasury Portfolio") and State Street Treasury Plus Money Market Portfolio (the "Treasury Plus Portfolio") (collectively, the "Portfolios"). In preparation for considering the Advisory Agreements, the Trustees had thoroughly reviewed the renewal materials provided by the investment adviser, which they had requested through independent counsel. In deciding whether to renew the Advisory Agreements, the Trustees considered various factors, including (i) the nature, extent and quality of the services provided by the SSgA Funds Management, Inc. (the "Adviser") under the Advisory Agreements, (ii) the investment performance of the Portfolios, (iii) the costs to the Adviser of its services and profits realized by the Adviser and its affiliates from their relationship with the Trust, (iv) the extent to which economies of scale would be realized if and as the Trust grows and whether the fee levels in the Advisory Agreements reflect these economies of scale, and (v) any additional benefits to the Adviser from its relationship with the Trust. In considering the nature, extent and quality of the services provided by the Adviser, the Trustees relied on their prior direct experience as Trustees of the Trust as well as on the materials provided at the Meeting. The Board reviewed the Adviser's responsibilities under the Advisory Agreements and noted the experience and expertise that would be appropriate to expect of an adviser to the Portfolios, which are money market funds. The Trustees reviewed the background and experience of the Adviser's senior management, including those individuals responsible for the investment and compliance operations relating to the investments of the Portfolios, and the responsibilities of the latter with respect to the Portfolios. They also considered the resources, operational structures and practices of the Adviser in managing the Portfolios' investments, in monitoring and securing the Portfolios' compliance with their investment objectives and policies with respect to their investments and with applicable laws and regulations, and in seeking best execution of portfolio transactions. The Trustees also considered STATE STREET MASTER FUNDS GENERAL INFORMATION (UNAUDITED) DECEMBER 31, 2008 (CONTINUED) information about the Adviser's overall investment management business, noting that the Adviser manages assets for a variety of institutional investors and that the Adviser and its affiliates had over $1.69 trillion in assets under management as of September 30, 2008, including over $157 billion managed by the Adviser. They reviewed information regarding State Street's business continuity and disaster recovery program. Drawing upon the materials provided and their general knowledge of the business of the Adviser, the Trustees determined that the experience, resources and strength of the Adviser in the management of money market products are exceptional. As discussed more fully below, they also determined that the advisory fees for the Portfolios were fair and reasonable and that their performance and expense ratios were satisfactory. On the basis of this review, the Trustees determined that the nature and extent of the services provided by the Adviser to the Portfolios were appropriate, had been of uniformly high quality, and could be expected to remain so. The Trustees noted that, in view of the investment objectives of the Portfolios, the investment performance was satisfactory. The Trustees noted that, for the Money Market Portfolio and the Tax Free Portfolio, materials provided by Lipper Inc. at the Meeting indicated that the Portfolios' performance had been above average for their respective Lipper peer groups for the reported (three-year, one-year and year-to-date, as applicable) periods ending September 30, 2008. For the U.S. Government Portfolio, the Treasury Portfolio and the Treasury Plus Portfolio, none of which had yet posted one-year performance data, the Board determined that there was not yet sufficient information to draw meaningful conclusions about their performance. The Board concluded that, to the extent that meaningful performance data were available, the performance of the Portfolios was satisfactory. The Trustees considered the profitability to the Adviser and its affiliate, State Street, of the advisory relationships to the Trust. The Trustees had been provided with data regarding the profitability to the Adviser and its affiliated service providers with respect to the Portfolios individually, and on an aggregate basis, for the year ended June 30, 2008. Having discussed with representatives of the Adviser the methodologies used in computing the costs that formed the bases of the profitability calculations, they concluded that these methodologies were reasonable and turned to the data provided. After discussion and analysis they concluded that, to the extent that the Adviser's and State Street's relationships with the Trust had been profitable to either or both those entities, the profitability was in no case such as to render the advisory fees excessive. In order better to evaluate the Portfolios' advisory fees, the Trustees had requested comparative information from Lipper Inc. with respect to fees paid by, and expense ratios of, similar funds. The Trustees found that the Portfolios' advisory fees and total expense ratios were lower than the average for their peer groups; after discussion, they concluded that the data available provided confirmation of the reasonableness of the Adviser's fees. The Board also considered that to help limit expenses of the Money Market Portfolio and the Tax Free Portfolio, the Adviser had reduced its advisory fee or otherwise reimbursed expenses for those Portfolios. The Board determined that the Adviser's fees were fair and reasonable. In considering whether the Adviser benefits in other ways from its relationship with the Trust, the Trustees also considered whether the Adviser's affiliates may benefit from the Trust's relationship with State Street as fund administrator and custodian. They noted that the Adviser utilizes no soft-dollar arrangements in connection with the Portfolios' brokerage transactions. The Trustees concluded that, to STATE STREET MASTER FUNDS GENERAL INFORMATION (UNAUDITED) DECEMBER 31, 2008 (CONTINUED) the extent that the Adviser or its affiliates derive other benefits from their relationships with the Trust, those benefits are not so significant as to render the Adviser's fees excessive. The Board also considered the extent to which economies of scale may be realized by the Portfolios as assets grow and whether the Portfolios' fee levels reflect such economies of scale, if any, for the benefit of investors. In considering the matter, the Board determined that, to the extent economies of scale were in fact realized, such economies of scale were shared with the Portfolios by virtue of advisory fees of comparatively low levels that subsumed economies of scale in the fees themselves. The Trustees also recognized, however, that should sustained, substantial asset growth be realized in the future, it might be necessary to consider additional measures. On the basis of the foregoing discussions and determinations, without any one factor being dispositive, the Board decided to approve the continuance of the Advisory Agreements.

Box 5049 Boston, MA 02206 STATE STREET EQUITY 500 INDEX PORTFOLIO ANNUAL REPORT DECEMBER 31, 2008 STATE STREET EQUITY 500 INDEX PORTFOLIO The State Street Equity 500 Index Portfolio (the "Portfolio") seeks to match as closely as possible, before expenses, the performance of the Standard & Poor's 500 Composite Stock Price Index (the "Index"). In seeking this objective, the Portfolio utilizes a passive management strategy designed to track the performance of the Index. For the 12-month period ended December 31, 2008 (the "Reporting Period"), the total return for the Portfolio was -37.02%, and the total return for the Index was -37.00%. The Portfolio and Index returns reflect the reinvestment of dividends and other income. The Portfolio's performance reflects the expenses of managing the Portfolio, including brokerage and advisory expenses. The Index is unmanaged and Index returns do not reflect fees and expenses of any kind, which would have a negative impact on returns. Equity markets in 2008 will be reviewed and studied for years to come. The S&P 500 fell 37% during the year. It was the worst showing in U.S equity markets since the 1930s. There were many headlines during the year and much of the news concerning the stock market was not positive. The year started with a futures position that cost Societe Generale billions of dollars in losses. Stress in the debt markets created ripple effects into the stock market and the broad economy. In March, Bear Stearns was rescued from the brink of bankruptcy when the government arranged a takeover by JP Morgan Chase. As summer approached, commodity prices continued to rise. Oil hovered near $140 per barrel at the end of June and inflation and recession fears were widespread in the market. Liquidity in fixed income and money markets was poor throughout the period, but the worst was yet to come. In early September, the markets began one of the wildest periods in history. In the span of a few weeks: Lehman Brothers filed for bankruptcy; Merrill Lynch entered a merger with Bank of America; Fannie Mae and Freddie Mac were nationalized; Morgan Stanley and Goldman Sachs became bank holding companies; AIG received a government loan ($85 billion at announcement, later increasing to over $100 billion;) and Washington Mutual one of the country's largest banks was taken over by the Federal Deposit Insurance Corporation (the "FDIC"). During the same period, money markets effectively froze and the flight to quality was such a rush that T-Bills traded with negative yields. Governments across the globe responded with multiple policies to restore confidence in the markets. Capital was invested into banks, money market funds were temporarily guaranteed, FDIC insurance was increased, short term debt facilities were created to increase liquidity and confidence, interest rates were cut to historical lows, money supplies were dramatically increased, and fiscal stimulus plans were launched. December had some bright spots as equity markets improved off their November lows and conditions in the credit markets showed some improvement. While it is too early to tell if the markets have turned, the extreme volatility seems to have subsided for the moment. Markets ended the year with news of an alleged Ponzi scheme involving a very large hedge fund. While this news did not directly impact capital markets, it was another blow to already weary investors. Equity markets were hit hard across every size, sector and region during 2008. Large and small, value and growth, EAFE and Emerging, all took significant losses during the year. The Index fell 37.00%, Russell 2000 Index fell 33.79%, MSCI EAFE Index fell 43.38%, and MSCI Emerging Markets Index fell 53.33%. Russell 1000 Value Index fell 37.60% while Russell 1000 Growth fell 38.44%. Within the Index, all 10 sectors lost value during the year. Consumer Staples, historically known as a defensive sector, was the top performing sector Two other "defensive" sectors, Healthcare and Utilities, although they lost value during the year, performed well in comparison to the remaining seven sectors. Given some of the headlines mentioned above, it is no surprise that Financials took the biggest losses during the year. The Financials sector was the poorest performer during the year, as once mighty institutions took huge losses and a number of 2 bankruptcies hit the sector. Materials and Information Technology also suffered greatly during the year. These sectors have historically been more sensitive to economic cycles, and the Materials sector was also hit by crashing commodity prices in the second half of the year. There were some individual bright spots during the year: discount retailers Family Dollar Stores and Wal-Mart recorded gains. These companies benefited from a shift in consumer preferences toward low cost retailers. Amgen and Barr Pharmaceuticals fared well as the Healthcare sector is less vulnerable to changes in economic conditions. Financial institutions placed in the bottom five of six spots on the return scale for the year. Lehman Brothers, Washington Mutual, Fannie Mae, Freddie Mac and AIG posted some of the worst returns in 2008. There were many other companies posting significant losses on equity value as the pain was widespread, but losses were particularly acute in the Financials sector. The views expressed above reflect those of the Fund's portfolio manager only through the Reporting Period, and do not necessarily represent the views of the Adviser as a whole. 3 STATE STREET EQUITY 500 INDEX PORTFOLIO GROWTH OF A $10,000 INVESTMENT (a) (PERFORMANCE GRAPH) State Street Equity 500 Index Portfolio S&P 500 (R) Index --------------- --------------- 3/1/2000 10,000 10,000 12/31/2000 9,671 9,662 12/31/2001 8,510 8,514 12/31/2002 6,623 6,633 12/31/2003 8,519 8,535 12/31/2004 9,444 9,464 12/31/2005 9,904 9,930 12/31/2006 11,465 11,498 12/31/2007 12,094 12,130 12/31/2008 7,617 7,642 INVESTMENT PERFORMANCE (a) For the Year Ended December 31, 2008 Total Return Total Return Total Return Average Annualized Since One Year Ended Five Years Ended Commencement of Operations December 31, 2008 December 31, 2008 (March 1, 2000) ----------------- ----------------- -------------------------- State Street Equity 500 Index Portfolio -37.02% -2.21% -2.90% S&P 500 (R) Index (b) -37.00% -2.19% -2.90% (a) Total returns and performance graph information represent past performance and are not indicative of future results, which may be lower or higher than performance data quoted.

This example is intended to help you understand your ongoing costs (in dollars) of investing in the Portfolio and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period shown and held for the entire period from July 1, 2008 to December 31, 2008. 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 December 31, 2008 BEGINNING ENDING ACCOUNT VALUE ACCOUNT VALUE EXPENSES PAID JULY 1, 2008 DECEMBER 31, 2008 DURING PERIOD * ------------- ----------------- --------------- BASED ON ACTUAL PORTFOLIO RETURN $1,000.00 $ 715.60 $0.19 BASED ON HYPOTHETICAL (5% RETURN BEFORE EXPENSES) $1,000.00 $1,024.91 $0.23 * The calculations are based on expenses incurred in the most recent six month period of the Portfolio.

STATE STREET EQUITY 500 INDEX PORTFOLIO NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2008 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 December 31, 2008, 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 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.) o - Level 3 - significant unobservable inputs (including the Portfolio's own assumptions in determining the fair value of investments) 18 STATE STREET EQUITY 500 INDEX PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2008 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 December 31, 2008, in valuing the Portfolio's assets carried at fair value: INVESTMENTS IN OTHER FINANCIAL VALUATION INPUTS SECURITIES INSTRUMENTS* - ---------------- -------------- --------------- Level 1 - Quoted Prices $1,515,960,091 $950,935 Level 2 - Other Significant Observable Inputs 4,810,926 -- Level 3 - Significant Unobservable Inputs -- -- -------------- -------- TOTAL $1,520,771,017 $950,935 -------------- -------- * Other financial instruments include futures contracts. SECURITIES TRANSACTIONS, INVESTMENT INCOME AND EXPENSES: Securities transactions are recorded on a trade date basis for financial statement purposes. Dividend income is recorded on the ex-dividend date. Interest income is recorded daily on the accrual basis and includes amortization of premium and accretion of discount on investments. Realized gains and losses from securities transactions are recorded on the basis of identified cost. Expenses are accrued daily based on average daily net assets. All of the net investment income and realized and unrealized gains and losses from the security transactions of the Portfolio are allocated pro rata among the partners in the Portfolio based on each partner's daily ownership percentage. FEDERAL INCOME TAXES: The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains because it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been "passed through" to the Portfolio's partners in proportion to their holdings in the Portfolio, regardless of whether such items have been distributed by the Portfolio. Each partner is responsible for tax liability based on its distributive share; therefore, no provision has been made for federal income taxes. The Portfolio has reviewed the tax positions for open years as of and during the year ended December 31, 2008, and determined it did not have a liability for any unrecognized tax expenses. The Portfolio recognizes interest and penalties, if any, related to tax liabilities as income tax expense in the Statement of Operations. As of December 31, 2008, 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. USE OF ESTIMATES: The Portfolio's financial statements are prepared in accordance with U.S. generally accepted accounting principles that require the use of management estimates. Actual results could differ from those estimates. 19 STATE STREET EQUITY 500 INDEX PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2008 3. SECURITIES TRANSACTIONS For the year ended December 31, 2008, purchases and sales of investment securities, excluding short-term investments, futures contracts, and contributions in-kind and fair value of withdrawals, aggregated to $307,643,773 and $281,597,781, respectively. At December 31, 2008, the book cost of investments was $1,485,867,258 which approximates cost computed on a federal tax basis. The aggregate gross unrealized appreciation and gross unrealized depreciation was $357,487,087 and $322,583,328, respectively, resulting in net appreciation of $34,903,759 for all securities as computed on a federal income tax basis. 4. RELATED PARTY FEES AND TRANSACTIONS The Portfolio has entered into an investment advisory agreement with SSgA Funds Management, Inc. ("SSgA FM" or the "Adviser"), a subsidiary of State Street Corporation and an affiliate of State Street Bank and Trust Company ("State Street"), under which SSgA FM directs the investments of the Portfolio in accordance with its investment objective, policies, and limitations. The Trust has contracted with State Street to provide custody, administration and transfer agent services to the Portfolio. In compensation for SSgA FM's services as investment adviser and for State Street's services as administrator, custodian and transfer agent (and for assuming ordinary operating expenses of the Portfolio, including ordinary legal, audit and trustees expense), State Street receives a unitary fee, calculated daily, at the annual rate of 0.045% of the Portfolio's average daily net assets. Certain investments made by the Portfolio were made in securities affiliated with State Street and SSgA FM. Investments in State Street Corporation, the holding company of State Street, were made according to its representative portion of the S&P 500(R) Index. The market value of this investment at December 31, 2008 is listed in the Portfolio of Investments. 5. TRUSTEES' FEES Pursuant to certain agreements with State Street and its affiliates, each Independent Trustee receives for his or her services a $30,000 retainer in addition to $2,500 for each in-person meeting and $500 for each telephonic meeting from State Street or its affiliates. 6. INDEMNIFICATIONS The Trust's organizational documents provide that its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. In addition, both in some of its principal service contracts and in the normal course of its business, the Trust enters into contracts that provide indemnifications to other parties for certain types of losses or liabilities. The Trust's maximum exposure under these arrangements is unknown as this could involve future claims against the Trust. Management does not expect any significant claims. 7. NEW ACCOUNTING PRONOUNCEMENTS 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 and 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. At this time, management is evaluating the implications of FAS 161 and believes the impact of adopting FAS 161 will be limited to additional disclosures. 20 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees of State Street Master Funds and Owners of Beneficial Interest of State Street Equity 500 Index Portfolio: We have audited the accompanying statement of assets and liabilities of the State Street Equity 500 Index Portfolio (one of the portfolios constituting State Street Master Funds) (the "Portfolio"), including the portfolio of investments, as of December 31, 2008, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Portfolio's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Portfolio's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Portfolio's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2008, by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of State Street Equity 500 Index Portfolio of State Street Master Funds at December 31, 2008, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

ADVISORY AGREEMENT RENEWAL The Board of Trustees of the Trust met on November 20, 2008 (the "Meeting") to consider the renewal of the investment advisory agreement for the Portfolio (the "Advisory Agreement"). In preparation for considering the Advisory Agreement, the Trustees had thoroughly reviewed the renewal materials provided by the investment adviser, which they had requested through independent counsel. In deciding whether to renew the Advisory Agreement, the Trustees considered various factors, including (i) the nature, extent and quality of the services provided by the SSgA Funds Management, Inc. (the "Adviser") under the Advisory Agreement, (ii) the investment performance of the Portfolio, (iii) the costs to the Adviser of its services and the profits realized by the Adviser and its affiliates from their relationship with the Trust, (iv) the extent to which economies of scale would be realized if and as the Trust grows and whether the fee levels in the Advisory Agreement reflect these economies of scale, and (v) any additional benefits to the Adviser from its relationship with the Trust. In considering the nature, extent and quality of the services provided by the Adviser, the Trustees relied on their prior direct experience as Trustees of the Trust as well as on the materials provided at the Meeting. The Board reviewed the Adviser's responsibilities under the Advisory Agreement and noted the experience and expertise that would be appropriate to expect of an adviser to the Portfolio, which is an index fund. The Trustees reviewed the background and experience of the Adviser's senior management, including those individuals responsible for the investment and compliance operations relating to the investments of the Portfolio, and the responsibilities of the latter with respect to the Portfolio. They also considered the resources, operational structures and practices of the Adviser in managing the Portfolio's investments, in monitoring and securing the Portfolio's compliance with its investment objective and policies with respect to its investments and with applicable laws and regulations, and in seeking best execution of portfolio transactions. The Trustees also considered information about the Adviser's overall investment management business, noting that the Adviser manages assets for a variety of institutional investors and that the Adviser and its affiliates had over $1.69 trillion in assets under management as of September 30, 2008, including over $157 billion managed by the Adviser. They reviewed information regarding State Street's business continuity and disaster recovery program. Drawing upon the materials provided and their general knowledge of the business of the Adviser, the Trustees determined that the experience, resources and strength of the Adviser in the management of index products are exceptional. As discussed more fully below, they also determined that the advisory fee for the Portfolio was fair and reasonable and that its performance and expense ratio were satisfactory. On the basis of this review, the Trustees determined that the nature and extent of the services provided by the Adviser to the Portfolio was appropriate, had been of uniformly high quality, and could be expected to remain so. 22 STATE STREET EQUITY 500 INDEX PORTFOLIO GENERAL INFORMATION (UNAUDITED) DECEMBER 31, 2008 (CONTINUED) The Trustees noted that, in view of the investment objective of the Portfolio, the investment performance was satisfactory. The Trustees noted that the performance of the Portfolio in absolute terms was not of the importance that normally attaches to that of actively-managed funds. Of more importance to the Trustees was the extent to which the Portfolio achieved its objective of replicating, before expenses, the total return of the S&P 500 Index. Drawing upon information provided at the Meeting and upon reports provided to the Trustees by the Adviser throughout the preceding year, they determined that the Portfolio had in fact tracked the index within an acceptable range of tracking error. They concluded that the performance the Portfolio was satisfactory. The Trustees considered the profitability to the Adviser and its affiliate, State Street, of the advisory relationships with the Trust. The Trustees had been provided with data regarding the profitability to the Adviser and its affiliated service providers with respect to the Portfolio individually, and on an aggregate basis, for the year ended June 30, 2008. Having discussed with representatives of the Adviser the methodologies used in computing the costs that formed the bases of the profitability calculations, they concluded that these methodologies were reasonable and turned to the data provided. After discussion and analysis they concluded that, to the extent that the Adviser's and State Street's relationships with the Trust had been profitable during the period for which information had been provided, the profitability was in no case such as to render the advisory fee excessive. In order better to evaluate the Portfolio's advisory fee, the Trustees had requested comparative information from Lipper Inc. with respect to fees paid by, and expense ratios of, similar funds. The Trustees found that the Portfolio's advisory fee and total expense ratio were lower than the average for its peer group; after discussion, they concluded that the data available provided confirmation of the reasonableness of the Adviser's fee. The Board determined that the Adviser's fee was fair and reasonable. In considering whether the Adviser benefits in other ways from its relationship with the Trust, the Trustees also considered whether the Adviser's affiliates may benefit from the Trust's relationship with State Street as fund administrator, custodian and transfer agent. They noted that the Adviser utilizes no soft-dollar arrangements in connection with the Portfolio's brokerage transactions. The Trustees concluded that, to the extent that the Adviser or its affiliates derive other benefits from their relationships with the Trust, those benefits are not so significant as to render the Adviser's fee excessive. The Board also considered the extent to which economies of scale may be realized by the Portfolio as assets grow and whether the Portfolio's fee levels reflect such economies of scale, if any, for the benefit of investors. In considering the matter, the Board determined that, to the extent economies of scale were in fact realized, such economies of scale were shared with the Portfolio by virtue of an advisory fee of a comparatively low level that subsumed economies of scale in the fee itself. The Trustees also recognized, however, that should sustained, substantial asset growth be realized in the future, it might be necessary to consider additional measures. On the basis of the foregoing discussions and determinations, without any one factor being dispositive, the Board decided to approve the continuance of the Advisory Agreement. 23 TRUSTEES AND EXECUTIVE OFFICERS (UNAUDITED).

Box 5049 Boston, MA 02206 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO (FORMERLY STATE STREET TAX FREE LIMITED DURATION BOND PORTFOLIO) ANNUAL REPORT DECEMBER 31, 2008 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO The State Street Short-Term Tax Exempt Bond Portfolio (the "Portfolio") seeks to provide federally tax-exempt current income and liquidity. The Portfolio is benchmarked to the Barclays Capital Municipal 1 Year Index ("the "Index"). For the 12-month period ended December 31, 2008 (the "Reporting Period"), the total return for the Portfolio was 2.93%, and the total return for the Index was 4.56%. The Portfolio and Index returns reflect the reinvestment of dividends and other income. The Portfolio's performance reflects the expenses of managing the Portfolio, including brokerage and advisory expenses. The Index is unmanaged and Index returns do not reflect fees and expenses of any kind, which would have a negative impact on returns. Calendar year 2008 proved to be one like no other for the municipal market. The market faced and endured numerous shocks and volatility spikes. Annualized volatility for high grade municipals of 10 year maturity doubled in 2008. The result was similar for longer bonds and even more pronounced on the short end of the yield curve. The first shock to hit the market was the fallout from the deterioration of the monoline bond insurers. When it first became questionable whether the major insurers could maintain their AAA ratings and some of the smaller insurers experienced downgrades, the auction mechanism for auction rate securities ("ARSs") began to fail. The resulting supply of ARS overwhelmed dealer desks and their interest rates spiked to attract buyers. Shortly thereafter, variable rate demand notes ("VRDNs") experienced a similar fate. Many VRDNs are derivatives of longer bonds, which are put into a trust wrapped with bond insurance. When insurance became questionable, the short rates on the VRDNs spiked and the long coupons were not adequate to cover the new rate. The VRDNs with the weakest insurance "wraps" were shunned by money funds. When money funds would not buy the short bonds, many of the derivative structures collapsed, thereby forcing large volumes of long bonds into the market causing their prices to decline as these structures were unwound.. The stress first experienced on the short end of the curve migrated to longer bonds and yields pushed higher. This was devastating for investors who had leveraged long positions in municipals. Massive unwinds of these positions caused many hedge funds and arbitrageurs to fold. The savior of the market this year has been the retail investor. Individuals have filled the buying void as well as they possibly could. Enticed by the high yields, individuals entered during periods of stress to pick up bargains. Retail investors provided much needed demand and the municipal market fluctuated between periods of intense sell-offs followed by strong rallies. The second major shock that took out the lows experienced during February was the Lehman Brothers bankruptcy and the government takeover of AIG. These shocks caused a major taxable money market fund to "break the buck," triggering a flight to quality in the Treasury market and taking most non-Treasury markets down. Municipals were no exception, and forced selling from leveraged accounts and mutual funds ensued. Finally, the biggest event of the fourth quarter was collateral calls received by the mutual funds, which forced many funds to liquidate positions. The market exhibited a similar pattern all year-an event would trigger a big sell off, retail investors would gradually provide support, and then markets would rally and stabilize. A new triggering event would occur, and the process would repeat itself. Another pattern experienced in 2008 was the movement toward a progressively steeper yield curve as the year wore on. January opened with spreads between 2 and 30 year maturities of 134 basis points. This spread widened during much of the year, peaking in mid-December at 371 basis points and closing the year at 317 basis points. A third consistent trend was the widening of credit spreads. As investors were burned by ARSs, the credit of monoline bond insurers deteriorated, and markets became more illiquid, investor confidence faded. The lack of confidence stimulated demand for only the highest of quality bonds. Ten-year spreads between AAA and BBB debt widened from 87 basis points in January to 312 basis points by year end. 2 The returns of the underlying components of the Barclay's Capital Municipal 1 Year Index*, which reflects the overall municipal bond market, demonstrated the volatility and disparity of returns due to sector, yield curve and credit quality over the course of the year: Municipal Bond Index -2.47% 5 Year Index 5.78% Long Bond Index -14.68% General Obligation Index 1.50% Revenue Bond Index -6.31% Pre-refunded Index 6.78% Industrial Development/Pollution Control (includes tobacco) -23.51% Water and Sewer Index -0.86% Hospital Index -12.34% AAA Rated Index 1.61% BBB Rated Index -21.33% * The Portfolio changed it's benchmark during the year from the IMoneyNet MFR Tax-Free Index to the Barclay's Capital Municipal 1 Year Index. The Portfolio believes that the Barclays Capital Municipal 1 Year Index (1) provides a better comparison against the broad market of securities in which the Portfolio investments, and (2) contains securities with an average duration that more closely reflected the Portfolio's shift toward a longer-duration portfolio. In 2008 individual credit, or what you owned, and maturity, or what portion of the curve you owned it, had a tremendous impact on total return. Effects of the slowing economy are beginning to be felt by municipalities. Deficit projections are widening for States. While only a few municipalities have entered or are close to bankruptcy, the credit pressures are building on all municipalities and will likely be the central theme of 2009. States are lining up for federal government relief and the municipal credit story is evolving. With the flatness of the municipal yield curve through much of 2007, the Portfolio maintained a very short duration. In 2008, the Portfolio used opportunities in the markets to extend duration, pick up yield, and become more closely aligned with characteristics of the Index. The best performing sub-sector of the municipal market was pre-refunded bonds. The Portfolio was underweight in this sub-sector. General obligation bonds were the next best performing sub-sector, where the Portfolio held an overweighting thereby contributing to Portfolio returns. At year end the Portfolio is of similar credit quality and duration to its benchmark. The views expressed above reflect those of the Portfolio's portfolio manager only through the Reporting Period, and do not necessarily represent the views of the Adviser as a whole. Investment decisions for any mutual fund are made based upon a variety of factors; therefore this discussion should not be relied on as an indication of the investment decisions for any fund managed by the Adviser. 3 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO GROWTH OF A $10,000 INVESTMENT (a) (PERFORMANCE GRAPH) State Street iMoney Net Barclays Short-Term Tax Tax-Free National Capital 1-Year Exempt Bond Institutional Municipal x Portfolio Average Bond Index - --------- -------------- ----------------- -------------- 2/7/07 10,000 10,000 10,000 3/31/07 10,053 10,053 10,072 6/30/07 10,143 10,138 10,138 9/30/07 10,240 10,224 10,274 12/31/07 10,333 10,305 10,418 3/31/08 10,421 10,367 10,597 6/30/08 10,425 10,414 10,639 9/30/08 10,482 10,467 10,705 12/31/08 10,648 10,512 10,892 INVESTMENT PERFORMANCE (a) For the Fiscal Year Ended December 31, 2008 Total Return Total Return Average Annualized Since for the Year Ended Commencement of Operations December 31, 2008 (February 7, 2007) ------------------ -------------------------- State Street Short-Term Tax Exempt Bond Portfolio 3.04% 3.36% iMoney Net Tax-Free National Institutional 2.01% 2.64% Average (b) Barclays Capital 1-Year Municipal 4.56% 4.62% Bond Index (c) (a) Total returns and performance graph information represent past performance and are not indicative of future results, which may be lower or higher than performance data quoted. Investment return and principal value of an investment will fluctuate so that an investor's share, when redeemed, may be worth more or less than its original cost. The graph and table above do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Investment performance reflects fee waivers in effect. In the absence of fee waivers, total return would be lower. (b) The iMoney Net Tax-Free National Institutional Average is an aveage that consists of all national tax-free and municipal institutional funds. Portfolio Holdings of tax-free funds include rated and unrated demand notes, rated and unrated general market notes, commercial paper, put bonds - 6 months & less, put bonds - over 6 months, AMT paper, and other tax-free holdings. It is not possible to invest directly in an average. (c) Barclays Capital 1-Year Municipal Bond Index: A total return benchmark designed for tax-exempt assets. The index includes bonds with a minimum credit rating of BAA3, are issued as part of a deal of at least $50 million, have an amount outstanding of at least $5 million, have maturities of 1 to 2-years, and have been issued after December 31, 1990. The Portfolio changed it's benchmark during the year from the iMoney Net Tax-Free Index to the Barclay's Capital Municipal 1 Year Index. The Portfolio believes that the Barclays Capital Municipal 1 Year Index (1) provides a better comparison against the broad market of securities in which the Portfolio invests, and (2) contains securities with an average duration that more closely reflected the Portfolio's shift toward a longer-duration portfolio. 4 STATE STREET INSTITUTIONAL SHORT-TERM TAX EXEMPT BOND PORTFOLIO EXPENSE EXAMPLE 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 July 1, 2008 to December 31, 2008. 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 December 31, 2008 BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING JULY 1, 2008 DECEMBER 31, 2008 PERIOD * ------------- ----------------- ------------- BASED ON ACTUAL PORTFOLIO RETURN $1,000.00 $1,021.30 $0.51 BASED ON HYPOTHETICAL (5% RETURN BEFORE EXPENSES) $1,000.00 $1,024.63 $0.51 * The calculations are based on expenses incurred in the most recent six month period of the Portfolio. The Portfolio's annualized average weighted expense ratio as of December 31, 2008 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. 5 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO PORTFOLIO STATISTICS (UNAUDITED) DECEMBER 31, PORTFOLIO COMPOSITION* 2008 -

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 (formerly State Street Tax Free Limited Duration 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 December 31, 2008, 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) 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 December 31, 2008, in valuing the Portfolio's assets carried at fair value: 15 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2008 INVESTMENTS IN VALUATION INPUTS SECURITIES -------------- Level 1 - Quoted Prices $ -- Level 2 - Other Significant Observable Inputs 100,106,084 ------------ Level 3 - Significant Unobservable Inputs -- ------------ TOTAL $100,106,084 ------------ SECURITIES TRANSACTIONS, INVESTMENT INCOME AND EXPENSES: Securities transactions are recorded on a trade date basis for financial statement purposes. Interest income is recorded daily on the accrual basis and includes amortization of premium and accretion of discount on investments. Realized gains and losses from securities transactions are recorded on the basis of identified cost. Expenses are accrued daily based on average daily net assets. All of the net investment income and realized and unrealized gains and losses from the security transactions of the Portfolio are allocated pro rata among the partners in the Portfolio based on each partner's daily ownership percentage. FEDERAL INCOME TAXES: The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains because it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been "passed through" to the Portfolio's partners in proportion to their holdings in the Portfolio, regardless of whether such items have been distributed by the Portfolio. Each partner is responsible for tax liability based on its distributive share; therefore, no provision has been made for federal income taxes. The Portfolio has reviewed the tax positions for open years as of December 31, 2008, and determined 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 December 31, 2008, 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 year ended December 31, 2008, purchases and sales of investment securities, excluding short-term investments, futures contracts, and in-kind contributions and withdrawals, aggregated to $108,465,044 and $55,907,500, respectively. At December 31, 2008, the book cost of investments was $99,503,061 which approximates cost computed on a federal tax basis. The aggregate gross unrealized appreciation and gross unrealized depreciation was $673,255 and $70,232, respectively, resulting in net appreciation of $603,023 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 has contractually agreed to cap the total operating expenses of the Portfolio at 0.10% of the Portfolio's average daily net assets until April 30, 2009. For the year ended December 31, 2008, SSgA FM reimbursed the Portfolio $86,031 under this agreement. State Street is the administrator, custodian and transfer agent for the Portfolio. In compensation for State Street's services as administrator, custodian and transfer agent, the Trust pays State Street an annual fee, which is accrued daily at the applicable 16 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2008 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 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. NEW ACCOUNTING PRONOUNCEMENTS 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 and 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. At this time, management is evaluating the implications of FAS 161 and believes the impact of adopting FAS 161 will be limited to additional disclosures. 17 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees of State Street Master Funds and Owners of Beneficial Interest of State Street Tax Short-Term Tax Exempt Bond Portfolio: We have audited the accompanying statement of assets and liabilities of the State Street Short-Term Tax Exempt Bond Portfolio (formerly State Street Tax Free Limited Duration Bond Portfolio (one of the portfolios constituting State Street Master Funds) (the "Portfolio"), including the portfolio of investments, as of December 31, 2008, and the related statement of operations for the year then ended, and the statements of changes in net assets and financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Portfolio's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Portfolio's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Portfolio's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2008, by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the State Street Short-Term Tax Exempt Bond Portfolio of State Street Master Funds at December 31, 2008, and the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

ADVISORY AGREEMENT RENEWAL The Board of Trustees of the Trust met on November 20, 2008 (the "Meeting") to consider the approval of the investment advisory agreement (the "Advisory Agreement") for the Portfolio. In preparation for considering the Advisory Agreement, the Trustees had thoroughly reviewed the renewal materials provided by the investment adviser, which they had requested through independent counsel. In deciding whether to renew the Advisory Agreement, the Trustees considered various factors, including (i) the nature, extent and quality of the services provided by the SSgA Funds Management, Inc. (the "Adviser") under the Advisory Agreement, (ii) the investment performance of the Portfolio, (iii) the costs to the Adviser of its services and profits realized by the Adviser and its affiliates from their relationship with the Trust, (iv) the extent to which economies of scale would be realized if and as the Trust grows and whether the fee levels in the Advisory Agreement reflect these economies of scale, and (v) any additional benefits to the Adviser from its relationship with the Trust. In considering the nature, extent and quality of the services provided by the Adviser, the Trustees relied on their prior direct experience as Trustees of the Trust as well as on the materials provided at the Meeting. The Board reviewed the Adviser's responsibilities under the Advisory Agreement and noted the experience and expertise that would be appropriate to expect of an adviser to the Portfolio, which is a short-term bond fund. The Trustees reviewed the background and experience of the Adviser's senior management, including those individuals responsible for the investment and compliance operations relating to the investments of the Portfolio, and the responsibilities of the latter with respect to the Portfolio. They also considered the resources, operational structures and 19 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO GENERAL INFORMATION (UNAUDITED) DECEMBER 31, 2008 (CONTINUED) practices of the Adviser in managing the Portfolio's investments, in monitoring and securing the Portfolio's compliance with its investment objective and policies with respect to its investments and with applicable laws and regulations, and in seeking best execution of portfolio transactions. The Trustees also considered information about the Adviser's overall investment management business, noting that the Adviser manages assets for a variety of institutional investors and that the Adviser and its affiliates had over $1.69 trillion in assets under management as of September 30, 2008, including over $157 billion managed by the Adviser. They reviewed information regarding State Street's business continuity and disaster recovery program. Drawing upon the materials provided and their general knowledge of the business of the Adviser, the Trustees determined that the experience, resources and strength of the Adviser in the management of short-term bond products are exceptional. As discussed more fully below, they also determined that the advisory fee for the Portfolio was fair and reasonable and that its performance and expense ratio were satisfactory. On the basis of this review, the Trustees determined that the nature and extent of the services provided by the Adviser to the Portfolio were appropriate, had been of uniformly high quality, and could be expected to remain so. The Trustees noted that, in view of the investment objectives of the Portfolio, the investment performance was satisfactory. The Trustees noted that materials provided by Lipper Inc. at the Meeting indicated that the Portfolio's performance had been above average for the Lipper peer group for the reported (one-year and year-to-date) periods ending September 30, 2008. The Board concluded that the performance of the Portfolio was satisfactory. The Trustees considered the profitability to the Adviser and its affiliate, State Street, of the advisory relationships to the Trust. The Trustees had been provided with data regarding the profitability to the Adviser and its affiliated service providers with respect to the Portfolio individually, and on an aggregate basis, for the year ended June 30, 2008. Having discussed with representatives of the Adviser the methodologies used in computing the costs that formed the bases of the profitability calculations, they concluded that these methodologies were reasonable and turned to the data provided. After discussion and analysis they concluded that, to the extent that the Adviser's and State Street's relationships with the Trust had been profitable to either or both those entities, the profitability was in no case such as to render the advisory fees excessive. In order better to evaluate the Portfolio's advisory fees, the Trustees had requested comparative information from Lipper Inc. with respect to fees paid by, and expense ratios of, similar funds. The Trustees found that the Portfolio's advisory fees and total expense ratios were lower than the average for its peer group; after discussion, they concluded that the data available provided confirmation of the reasonableness of the Adviser's fee. The Board also considered that to help limit expenses of the Portfolio, the Adviser had reduced its advisory fee or otherwise reimbursed expenses. The Board determined that the Adviser's fees were fair and reasonable. 20 STATE STREET SHORT-TERM TAX EXEMPT BOND PORTFOLIO GENERAL INFORMATION (UNAUDITED) DECEMBER 31, 2008 (CONTINUED) In considering whether the Adviser benefits in other ways from its relationship with the Trust, the Trustees also considered whether the Adviser's affiliates may benefit from the Trust's relationship with State Street as fund administrator and custodian. They noted that the Adviser utilizes no soft-dollar arrangements in connection with the Portfolio's brokerage transactions. The Trustees concluded that, to the extent that the Adviser or its affiliates derive other benefits from their relationships with the Trust, those benefits are not so significant as to render the Adviser's fees excessive. The Board also considered the extent to which economies of scale may be realized by the Portfolio as assets grow and whether the Portfolio's fee levels reflect such economies of scale, if any, for the benefit of investors. In considering the matter, the Board determined that, to the extent economies of scale were in fact realized, such economies of scale were shared with the Portfolio by virtue of an advisory fee of a comparatively low level that subsumed economies of scale in the fees itself. The Trustees also recognized, however, that should sustained, substantial asset growth be realized in the future, it might be necessary to consider additional measures. On the basis of the foregoing discussions and determinations, without any one factor being dispositive, the Board decided to approve the continuance of the Advisory Agreement. 21 TRUSTEES AND EXECUTIVE OFFICERS (UNAUDITED).

(e)(1) Audit Committee Pre-Approval Policies and Procedures The Trust's Audit Committee Charter states the following with respect to pre-approval procedures: Pre-Approval Requirements. Before the independent accountants are engaged by the Trust to render audit or non-audit services, either: 1. The Audit Committee shall pre-approve all auditing services and permissible non-audit services (e.g., tax services) provided to the Trust. The Audit Committee may delegate to one or more of its members the authority to grant pre-approvals. Any decision of any member to whom authority is delegated under this section shall be presented to the full Audit Committee at its next regularly scheduled meeting; or 2. The engagement to render the auditing service or permissible non-audit service is entered into pursuant to pre-approval policies and procedures established by the Audit Committee. Any such policies and procedures must (1) be detailed as to the particular service and (2) not involve any delegation of the Audit Committee's responsibilities to the investment adviser. The Audit Committee must be informed of each service entered into pursuant to the policies and procedures. A copy of any such policies and procedures shall be attached as an exhibit to the Audit Committee Charter. De Minimis Exceptions to Pre-Approval Requirements. Pre-Approval for a service provided to the Trust other than audit, review or attest services is not required if: (1) the aggregate amount of all such non-audit services provided to the Trust constitutes not more than 5 percent of the total amount of revenues paid by the Trust to the independent accountants during the fiscal year in which the non-audit services are provided; (2) such services were not recognized by the Trust at the time of the engagement to be non-audit services; and (3) such services are promptly brought to the attention of the Audit Committee and are approved by the Audit Committee or by one or more members of the Audit Committee to whom authority to grant such approvals has been delegated by the Audit Committee prior to the completion of the audit. Pre-Approval of Non-Audit Services Provided to the Adviser and Certain Control Persons. The Audit Committee shall pre-approve any non-audit services proposed to be provided by the independent accountants to (a) the investment adviser and (b) any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Trust, if the independent accountants' engagement with the investment adviser or any such control persons relates directly to the operations and financial reporting of the Trust. It shall be the responsibility of the independent accountants to notify the Audit Committee of any non-audit services that need to be pre-approved. Application of De Minimis Exception: The De Minimis exception set forth above applies to pre-approvals under this Section as well, except that the "total amount of revenues" calculation is based on the total amount of revenues paid to the independent accountants by the Trust and any other entity that has its services approved under this Section (i.e., the investment adviser or any control person)." (e)(2) Percentages of Services None of the services described in paragraphs (b) through (d) of this Item were performed in reliance on paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X during the period of time for which such rule was effective. (f) Not applicable. (g) Total Fees Paid By Adviser and Certain Affiliates For the fiscal years ended December 31, 2008 and December 31, 2007, the aggregate non-audit fees billed by E&Y for services rendered to the Trust and the Adviser and any entity controlling, controlled by, or under common control with the Adviser that provided ongoing services to the Trust were $5,600,000 and $5,400,000, respectively.
