For most of 2005, stocks remained in one of the narrowest trading ranges in history. The year began with a slide after the strong fourth quarter of 2004, with cyclical and small capitalization stocks performing the worst out of the gate. January was characterized by mixed economic data, increasing interest rates, disappointing earnings reports, and climbing oil prices. The markets were able to reverse course in February, even as the productivity report showed a continued slowdown in productivity growth and oil prices continued to climb. In March, the markets resumed their downward slide experienced in January due to the combination of the trade deficit, mixed economic news, high oil prices, and rising interest rates. April began on the heels of a March economic soft spot, as retail sales, payrolls, and consumer and business sentiment weakened. For most of April, equity markets were dogged by continuing inflation concerns as oil climbed above $57 per barrel. April closed with the announcement of one of the biggest jumps in the Consumer Price Index (CPI) in several months, as the CPI rose 0.6% in March. May featured the announcement of slower-than-expected first quarter gross domestic product growth of 3.1%. Despite concerns around economic deceleration, slowing profit growth, and continued high oil prices, first quarter earnings reports remained strong. June brought a slowdown in the equity market rally that began in May as the specter of economic deceleration dampened markets. July was an impressive month for equity markets, despite the drag from a strong dollar, higher energy prices, and a major terror attack in London, which caused an immediate 4% drop in the S&P 500 Index. Investors quickly rebounded however, and the losses were recovered only one day later. August brought a reversal of July's rally, as higher oil prices continued to fan the fears of economic weakness, reaching a record high of $70 per barrel during the aftermath of Hurricane Katrina. Despite the downturn of U.S. equity markets in August, September turned slightly positive as improved profits in the energy sector provided a counterbalance to lagging retail, transportation, tourism, and insurance sectors. Equity markets slid again in October amid continued signs of a slower economy and renewed concerns about inflation. Despite a U.S. gross domestic product growth rate of 4.1% for the third quarter, short term interest rates rose, oil prices remained historically high, and consumer confidence declined. In November, equity markets were resilient in the face of Fed tightening, the energy shock, and the strength of the U.S. dollar, and rebounded because strong productivity and high margins resulted in good earnings and oil prices fell to the mid-$50 per barrel range from $70 per barrel. After posting gains for nearly six weeks, December saw equity markets finish on an uninspiring note as thin volume led to volatile movements in stock prices. Compounding the mixed results throughout the year and leaving investors uncertain about the direction of the economy heading into 2006, the yield curve inverted at the end of December, meaning long-term yields fell below short-term yields, historically a harbinger of an economic downturn. As expected, interest rates moved considerably during the year as the yield curve flattened dramatically and inverted at the close of 2005. The Federal Reserve through the Federal Open Market Committee ("FOMC") continued its "measured pace" of monetary tightening by raising the Federal Funds rate 25 basis points (0.25%) eight times during the year. This brought the Fed Funds rate to 4.25% from 2.25%. S&P is a trademark of The McGraw-Hill Companies, Inc. and has been licensed for use.

Past performance is not indicative of future performance. The investment return and principal value of an investment in the Fund will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Fund performance in the table above does not reflect the deduction of taxes a shareholder would pay on distributions or the redemption of shares. 2. Fund performance for the since inception period represents the total returns achieved by the Institutional Class from 12/31/96 up to 3/2/98, the inception date of the PlanAhead Class, and the returns of the PlanAhead Class since its inception. Expenses of the PlanAhead Class are higher than those of the Institutional Class. Therefore, total returns shown may be higher than they would have been had the PlanAhead Class been in existence since 12/31/96. Eight out of ten sectors in the S&P 500 Index (the "Index") had positive returns for 2005. The strongest performing sectors for 2005 were Energy and Utilities. Energy surged 31.3% for all of 2005, and Utilities tacked on an uncharacteristically exciting 16.8% for the full year. No other S&P sectors achieved anything close to double digits. The weakest sector in 2005 was Consumer Discretionary, which tumbled 6.3% for the year. Although showing some flashes of brilliance in the leisure and retail areas, the Consumer Discretionary names were weighed down by dauntingly severe conditions in the auto and media industries. The top contributing stocks to the Index's return for the twelve-month period ended December 31, 2005 were ExxonMobil Corp. (up 11.8%), Altria Group, Inc. (up 27.7%) and Apple Computer, Inc. (up 123.3%). The largest detractors for the year were Dell, Inc. (down 28.9%), IBM Corp. (down 15.8%) and Verizon Communications, Inc. (down 22.2%). As of December 30, 2005, the Fund's largest sector weightings were Financials (21.3% of assets), Information Technology (15.1% of assets), and Health Care (13.3% of assets), consistent with the top sector weightings in the Index. The investment manager continues to utilize a replication strategy, owning all 500 names in the S&P 500 Index in approximately the same weightings as the Index. Therefore, the Fund is expected to continue to meet its objective of closely tracking, before expenses, the return of its benchmark, the S&P 500 Index.

In fact, throughout the year, international equity markets outperformed U.S. equity markets. European equity markets performed well in 2005 as 14 of 16 European MSCI country indexes posted positive gains. A key reason behind the upbeat outlook for world economic growth was that inflation retreated in most regions, especially in Europe and Japan. Despite the July terrorist attacks in London, worries about the economic impact of hurricanes in the United States, and higher energy costs, European equity markets performed strongly in the second half of 2005. In December, European manufacturing growth grew at its fastest pace in 16 months, while German unemployment declined by its greatest amount in more than 15 years. Economic growth accelerated as companies stepped up their hiring and investment activity, which in turn increased optimism that consumers would spend more and bolster Europe's export-driven economy. The strongest-performing European markets of 2005 were Austria, Denmark and Norway which gained 24.64%, 24.50% and 24.26% respectively. Ireland and Portugal returned -2.93% and -1.87%, respectively, and were the only two markets in Europe to post negative returns last year. The European Central Bank raised interest rates by 25 basis points (0.25%) for the first time since 2000, leaving the region's benchmark rate at 2.25%. In Asia, all five MSCI country indexes gained ground in 2005. Japan turned in the strongest growth in the region, returning 25.52%. Business confidence in that country climbed to its highest level in a year, and Japanese companies plan to invest in their businesses at the fastest pace since 1990, according to the Bank of Japan's Tankan business confidence survey. Other strong performers in the region included Australia (up 16.02%), Singapore (up 14.37%) and Hong Kong (up 8.40%). In 2005, the U.S. dollar gained 12.7% against the euro, 10.6% against the British pound and 15% against the Japanese yen. Exchange rates were largely driven by interest rate decisions and expectations in the United States. 7 PERFORMANCE OVERVIEW AMERICAN BEACON INTERNATIONAL EQUITY INDEX FUND(SM) December 31, 2005 (unaudited) - -------------------------------------------------------------------------------- For the twelve months ended December 31, 2005, the Institutional Class of the American Beacon International Equity Index Fund posted an impressive total return of 13.58%, closely tracking the MSCI EAFE Index return of 13.54% and underperforming the Lipper International Funds Index return of 15.67%.

Performance is that of the MSCI EAFE Index through 9/30/01, the MSCI Provisional EAFE Index from 10/1/01 through 5/31/02, and the MSCI EAFE Index thereafter. For the year, 19 of 21 countries in the MSCI EAFE Index ("EAFE") posted positive returns. The strongest-performing European markets of 2005 were Austria, Denmark and Norway, which gained 24.6%, 24.5% and 24.3%, respectively. Ireland and Portugal returned -2.3% and -1.9%, respectively, and were the only two countries in EAFE to post negative returns in 2005. In Asia, Japan turned in the strongest growth in the region, returning 25.5%. Other strong performers in Asia included Australia (up 16.0%) and Singapore (up 14.4%). Turning to sector performance, 9 of 10 EAFE sectors posted positive returns for the year, led by Materials (up 27.9%), Industrials (up 24.9%), and Energy (up 18.1%). The worst performing sectors were Telecommunication Services (down 12.4%), Consumer Staples (up 9.0%), and Consumer Discretionary (up 10.6%). The Fund continues to pursue its objective of closely replicating, before expenses, the return of its benchmark, the MSCI EAFE Index.

The examples below are intended to help you understand the ongoing cost (in dollars) of investing in a particular Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period in each Class and held for the entire period from July 1, 2005 through December 31, 2005. ACTUAL EXPENSES The following table provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the "Expenses Paid During Period" row estimate the expenses you paid on your account during this period. Shareholders of the PlanAhead and Institutional Classes that invest in the Fund through an IRA may be subject to a custodial IRA fee of $12 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $12 higher.

Annualized Expense Ratio...... 0.12% 0.15% 0.23% Annualized Expense Ratio..................... 0.60% </Table> HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The following table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed 5% per year rate of return before expenses (not the Fund's actual return). You may compare the ongoing costs of investing in a particular Fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. Shareholders of the PlanAhead and Institutional Classes that invest in the Fund through an IRA may be subject to a custodial IRA fee of $12 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $12 higher. You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs charged by a Fund. Similarly, the expense examples for other funds do not reflect any transaction costs charged by those funds, such as sales charges (loads), redemption fees or exchange fees. Therefore, the "Expenses Paid During Period" lines of the table are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If you were subject to any transaction costs during the period, your costs would have been higher.

These financial statements and financial highlights are the responsibility of the Funds' 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 Funds' 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 Funds' 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, 2005, by correspondence with the Master Portfolios. 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 American Beacon Funds at December 31, 2005, the results of their operations for the year then ended, the changes in their 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. -s- ERNST & YOUNG LLP Chicago, Illinois February 28, 2006 11 AMERICAN BEACON FUNDS STATEMENTS OF ASSETS AND LIABILITIES December 31, 2005 - -------------------------------------------------------------------------------- (in thousands, except share and per share amounts) <Table> <Caption> S&P 500 SMALL CAP INTERNATIONAL INDEX INDEX EQUITY INDEX ----------- ---------- ------------- ASSETS: Investment in master portfolio, at value................ $ 274,890 $ 46,184 $ 89,474 Receivable for fund shares sold......................... 394 1 758 ----------- ---------- ---------- TOTAL ASSETS........................................ 275,284 46,185 90,232 ----------- ---------- ---------- LIABILITIES: Payable for fund shares redeemed........................ 359 51 -- Administrative service fees payable (Note 2)............ 20 2 3 Other liabilities....................................... 63 19 29 ----------- ---------- ---------- TOTAL LIABILITIES................................... 442 72 32 ----------- ---------- ---------- NET ASSETS.................................................. $ 274,842 $ 46,113 $ 90,200 =========== ========== ========== ANALYSIS OF NET ASSETS: Paid-in capital......................................... $ 241,758 $ 41,281 $ 85,602 Undistributed net investment income..................... 11 -- (286) Accumulated net realized gain (loss)....................

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES American Beacon Funds (the "Trust"), formerly known as the American AAdvantage Funds, is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940 (the "Act"), as amended, as a no load, diversified, open-end management investment company. These financial statements and notes to the financial statements relate to the American Beacon S&P 500 Index Fund, the American Beacon Small Cap Index Fund and the American Beacon International Equity Index Fund (each a "Fund" and collectively, the "Funds"), each a series of the Trust. Each Fund invests all of its investable assets in a corresponding portfolio. The State Street Equity 500 Index Portfolio, Master Small Cap Index Series and the Master International Index Series (each a "Portfolio" and collectively the "Portfolios") are open-ended management investment companies registered under the Act. The value of such investment reflects each Fund's proportionate interest in the net assets of the corresponding Portfolio. <Table> <Caption> % OF PORTFOLIO HELD BY FUND AT AMERICAN BEACON: PORTFOLIOS: DECEMBER 31, 2005 - ---------------- ----------- ----------------- S&P 500 Index Fund State Street Equity 500 Index Portfolio 11.2% Small Cap Index Fund Master Small Cap Index Series 12.4% International Equity Index Fund Master International Index Series 17.1% </Table> The financial statements of the Portfolios are included elsewhere in this report and should be read in conjunction with the Funds' financial statements. American Beacon Advisors, Inc. (the "Manager"), formerly known as AMR Investment Services, Inc., is a wholly-owned subsidiary of AMR Corporation, the parent company of American Airlines, Inc. ("American"), and was organized in 1986 to provide business management, advisory, administrative and asset management consulting services to the Trust and other investors. The following is a summary of the significant accounting policies followed by the Funds. Class Disclosure The S&P 500 Index Fund has two classes of shares designed to meet the needs of different groups of investors. The following table sets forth the differences between the classes: <Table> <Caption> CLASS: OFFERED TO: SERVICE FEES: - ------ ----------- ------------- INSTITUTIONAL CLASS Investors making an initial investment of $2 million Administrative Service 0.05% Fee -- PLANAHEAD CLASS General public and investors investing through an Administrative Service 0.25% intermediary Fee -- 0.25% Service Fee -- </Table> Investment income, net capital gains (losses) and all expenses incurred by the S&P 500 Index Fund are allocated based on the relative net assets of each class, except for service fees and certain other fees and expenses related solely to one class of shares. Valuation of Investments Valuation of securities by each Portfolio is discussed in the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. - -------------------------------------------------------------------------------- 15 AMERICAN BEACON FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- Investment Income Each Fund records its share of net investment income and realized and unrealized gains and losses from the security transactions of its corresponding Portfolio each day. All net investment income and realized and unrealized gains (losses) of each Portfolio are allocated pro rata among the investors in that Portfolio at the time of such determination. Dividends to Shareholders Dividends from net investment income of the Small Cap Index and International Equity Index Funds normally will be declared and paid annually. The S&P 500 Index Fund normally will declare and pay dividends quarterly. Distributions, if any, of net realized capital gains are generally paid annually and recorded on the ex-dividend date. Dividends are determined in accordance with income tax principles that may treat certain transactions differently than generally accepted accounting principles. Allocation of Income, Expenses, Gains and Losses Income, expenses (other than those attributable to a specific class), gains and losses are allocated daily to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class. Valuation of Shares The price per share is calculated on each day on which shares are offered for sale and orders accepted or upon receipt of a redemption request. Net asset value per share is computed by dividing the value of each Fund's total assets (which includes the value of the Fund's investment in its Portfolio), less liabilities, by the number of Fund shares outstanding. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ from those estimates. Other Under the Trust's organizational documents, its officers and directors are indemnified against certain liability arising out of the performance of their duties to the Trust. In the normal course of business, the Trust enters into contracts that provide indemnification to the other party or parties against potential costs or liabilities. The Trust's maximum exposure under these arrangements is dependent on claims that may be made in the future and, therefore, cannot be estimated. The Trust has had no prior claims or losses pursuant to any such agreement. 2. FEES AND TRANSACTIONS WITH AFFILIATES Administrative Services Agreement The Manager and the Trust entered into an Administrative Services Agreement that obligates the Manager to provide or oversee administrative and management services to each Fund. As compensa- - -------------------------------------------------------------------------------- 16 AMERICAN BEACON FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- tion for performing the duties required under the Administrative Services Agreement, the Manager receives an annualized fee of 0.05% of the average daily net assets of the Institutional Class of the S&P 500 Index Fund, International Equity Index Fund, and Small Cap Index Fund and an annualized fee of 0.25% of the average daily net assets of the PlanAhead Class of the S&P 500 Index Fund. Service Agreement The Manager and the Trust entered into a Service Agreement that obligates the Manager to oversee additional shareholder servicing of the PlanAhead Class of the S&P 500 Index Fund. As compensation for performing the duties required under the Service Agreement, the Manager receives 0.25% of the average daily net assets of the PlanAhead Class of the S&P 500 Index Fund. Expense Reimbursement Plan The Funds have adopted an Expense Reimbursement Plan whereby the Manager may seek repayment of fees waived or expenses reimbursed for a period of up to three years. However, reimbursement will occur only if the Class' average net assets have grown or expenses have declined sufficiently to allow reimbursement without causing its expense ratio to exceed the previously agreed upon contractual expense limit. The S&P 500 Index Fund waived fees or reimbursed expenses of $5,000 and are subject to potential recovery expiring in 2006. The Funds have not recorded a liability for this potential reimbursement due to the assessment that a reimbursement is unlikely. Other Certain officers or Trustees of the Trust are also current or former officers or employees of the Manager or American. The Trust makes no direct payments to its officers. Mr. Feld and the non-interested Trustees (other than Mr. O'Sullivan) and their spouses are provided free unlimited air transportation on American. Retired Trustees and their spouses are provided free transportation on American, up to a maximum annual value of $40,000. The Trust compensates each Trustee with payments in an amount equal to the Trustee's income tax on the value of this free airline travel. Mr. O'Sullivan, as a retiree of American, already receives flight benefits. This Trustee receives an annual retainer of $40,000 plus $1,250 for each Board meeting attended. At December 31, 2005, the employee benefit plans of AMR Corporation and its subsidiary companies owned 88.2% of the Institutional Class of the S&P 500 Index Fund, 98.4% of the Small Cap Index Fund and 50.8% of the International Equity Index Fund. 3. FEDERAL INCOME AND EXCISE TAXES It is the policy of each of the Funds to comply with the requirements of Subchapter M of the Internal Revenue Code and to distribute substantially all net investment income as well as any net realized capital gains on the sale of investments. Therefore, no federal income tax provision is required. Dividends are determined in accordance with federal income tax regulations which may treat certain transactions differently than U.S. generally accepted accounting principles. Accordingly, the character of distributions and composition of net assets for tax purposes may differ from those reflected in the accompanying financial statements. - -------------------------------------------------------------------------------- 17 AMERICAN BEACON FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- The tax character of distributions during the fiscal years ended December 31, 2005 and December 31, 2004 were as follows (in thousands): <Table> <Caption> INTERNATIONAL S&P 500 INDEX SMALL CAP INDEX EQUITY INDEX --------------- --------------- ------------- YEAR ENDED YEAR ENDED YEAR ENDED DECEMBER 31, DECEMBER 31, DECEMBER 31, --------------- --------------- ------------- 2005 2004 2005 2004 2005 2004 ------ ------ ------ ------ ------ ---- Distributions paid from: Ordinary Income:* Institutional Class..................... $4,029 $4,253 $ 606 $1,104 $2,005 $617 PlanAhead Class......................... 677 670 -- -- -- -- Long-term capital gain Institutional Class..................... -- -- 521 1,090 -- -- Return of capital Institutional Class..................... 59 -- 167 -- 778 -- PlanAhead Class......................... 11 -- -- -- -- -- ------ ------ ------ ------ ------ ---- TOTAL TAXABLE DISTRIBUTIONS.................. $4,776 $4,923 $1,294 $2,194 $2,783 $617 ====== ====== ====== ====== ====== ==== </Table> * For tax purposes short-term capital gains distributions are considered ordinary income distributions.

Financial records are not adjusted for temporary differences. The temporary differences between financial reporting and tax-basis reporting of unrealized appreciation/(depreciation) are attributable primarily to the tax deferral of wash sales, the realization for tax purposes of unrealized gains/(losses) on certain derivative instruments, the tax treatment of income from investments in real estate investment trusts, and the realization for tax purposes of unrealized gains /(losses) on investments in passive foreign investment companies. Due to the inherent differences in the recognition of income, expenses and realized gains/(losses) under the U.S. generally accepted accounting principles and federal income tax regulations, permanent differences between book and tax reporting have been identified and appropriately reclassified on the Statement of Assets and Liabilities without impacting the net assets of the Fund. These differences are due primarily to the tax treatment of income from real estate - -------------------------------------------------------------------------------- 18 AMERICAN BEACON FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- investment trusts, foreign exchange gains/(losses) and gains/(losses) arising from redemption-in-kind transactions.

The S&P 500 Index Fund had $23 of expired capital loss carryovers. Net capital and foreign currency losses incurred after October 31, 2005 and within the taxable year are deemed to arise on the first business day of the Fund's next taxable year. For the year ended December 31, 2005, International Equity Index Fund deferred $58,742 of currency losses to January 1, 2006. 4.

ORGANIZATION State Street Master Funds (the "Trust") is a registered and diversified open-end investment company, as defined in the Investment Company Act of 1940, as amended (the "1940 Act"), that was organized as a business trust under the laws of the Commonwealth of Massachusetts on July 27, 1999. The Trust comprises six 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, 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, 2005, only the Portfolio and the State Street Money Market Portfolio were in operation. Pursuant to the Trust's Declaration of Trust, the Board of Trustees may 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. Securities Transactions, Investment Income and Expenses Securities transactions are recorded on a trade date basis. 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. - -------------------------------------------------------------------------------- 39 STATE STREET EQUITY 500 INDEX PORTFOLIO NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- 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. 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 (the "SEC") 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. Securities Lending The Trust, on behalf of the Portfolio, had entered into a Securities Lending Agreement (the "Agreement") with State Street Bank and Trust Company ("State Street") whereby the Portfolio would lend portfolio securities to qualified borrowers in order to earn additional income. On September 27, 2005, the Agreement was terminated and the Portfolio discontinued lending portfolio securities. The Agreement required that loans be secured at all times by cash, U.S. Government securities, sovereign debt, or irrevocable lines of credit in an amount at least equal to 102% of the market value of domestic securities loaned (105% in the case of foreign securities), plus accrued interest and dividends, determined on a daily basis. Proceeds collected by State Street on investment of cash collateral or any fee income was allocated as follows: 75% to the Portfolio and 25% to State Street. For the year ended December 31, 2005, the earned income for the Portfolio and State Street was $102,925 and $34,308, respectively. 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. - -------------------------------------------------------------------------------- 40 STATE STREET EQUITY 500 INDEX PORTFOLIO NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- 3. SECURITIES TRANSACTIONS For the year ended December 31, 2005, purchases and sales of investment securities, excluding short-term investments, futures contracts, and in-kind withdrawals, aggregated to $205,795,356 and $324,324,748, respectively. The aggregate value of in-kind withdrawals was $237,847,807. At December 31, 2005, the tax cost of investments was $1,952,530,390. The aggregate gross unrealized appreciation and gross unrealized depreciation was $801,244,221 and $304,603,493, respectively, resulting in net appreciation of $496,640,728 for all securities as computed on a federal income tax basis. The differences between book and tax cost amounts are primarily due to wash sale loss deferrals. 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 Corp. and an affiliate of 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), 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 made with cash collateral received from securities loaned were used to purchase shares of the State Street Navigator Securities Lending Prime Portfolio, which is offered by State Street and advised by SSgA FM. Investments in State Street Corp., the holding company of State Street, were made according to its representative portion of the S&P 500(R) Index. The market value of each of these investments at December 31, 2005 is listed in the Portfolio of Investments. 5. INDEMNIFICATIONS Like many other companies, 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. - -------------------------------------------------------------------------------- 41 STATE STREET EQUITY 500 INDEX PORTFOLIO REPORT OF ERNST & YOUNG LLP, 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, including the portfolio of investments, of the State Street Equity 500 Index Portfolio (one of the portfolios constituting State Street Master Funds)(the Portfolio) as of December 31, 2005, and the related statement of operations for the year then ended, the statements 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, 2005, by correspondence with the custodian and brokers or other appropriate auditing procedures where replies from the brokers were not received. 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 Equity 500 Index Portfolio of State Street Master Funds at December 31, 2005, 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. -s- ERNST & YOUNG LLP Boston, Massachusetts February 16, 2006 - -------------------------------------------------------------------------------- 42 STATE STREET EQUITY 500 INDEX PORTFOLIO GENERAL INFORMATION December 31, 2005 - -------------------------------------------------------------------------------- PROXY VOTING POLICIES AND PROCEDURES AND RECORD The Trust has adopted proxy voting procedures relating to portfolio securities held by the Portfolio.

ADVISORY AGREEMENT RENEWAL The Board of Trustees of the Trust met on November 16, 2005 (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 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 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 the relationship with the Portfolio and Trust, (iv) the extent to which economies of scale would be realized if and as the Portfolio 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 Portfolio and 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 $1.4 trillion in assets under management. 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 - -------------------------------------------------------------------------------- 43 STATE STREET EQUITY 500 INDEX PORTFOLIO GENERAL INFORMATION -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- the experience, resources and strength of the Adviser in the management of index products is 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 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. Accordingly, 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 September 30, 2005. They first discussed with representatives of the Adviser the methodologies used in computing the costs that formed the bases of the profitability calculations. Concluding that these methodologies were reasonable, they 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 of those entities, 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 that the Portfolio's advisory fee and total expense ratio were lower than the average for its peer group. The Trustees concluded that the data available provided confirmation of the reasonableness of the Adviser's fee. 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, custodian and transfer agent and the Portfolio's use of State Street Global Markets to perform certain brokerage services. 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, in view of the comparatively small asset size of the Portfolio, the economies of scale actually realized, if any, were minor and that, in any event, such economies of scale, if any, were shared with the Portfolio by virtue of advisory fees of comparatively low levels that subsumed economies of scale in the fees themselves. - -------------------------------------------------------------------------------- 44 STATE STREET EQUITY 500 INDEX PORTFOLIO TRUSTEES AND EXECUTIVE OFFICERS - -------------------------------------------------------------------------------- The table below includes information about the Trustees and Executive Officers of the State Street Master Funds, including their: - business addresses and ages; - principal occupations during the past five years; and - other directorships of publicly traded companies or funds.

SIGNIFICANT ACCOUNTING POLICIES: Master Small Cap Index Series (the "Series"), a non-diversified investment company, is part of Quantitative Master Series Trust (the "Trust"). The Trust is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interests in the Trust, subject to certain limitations. The Series' financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The following is a summary of significant accounting policies followed by the Series. (a) Valuation of Investments Equity securities that are held by the Series that are traded on stock exchanges or the Nasdaq National Market are valued at the last sale price or official close price on the exchange, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Trust. Long positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Trust. Short positions traded in the OTC market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written are valued at the last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last asked price. Options purchased are valued at their last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last bid price. Swap agreements are valued based upon quoted fair valuations received daily by the Series from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless the Investment Adviser believes that this method no longer produces fair valuations. Repurchase agreements are valued at cost plus accrued interest. The Series employs pricing services to provide certain securities prices for the Series. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Trust, including valuations furnished by the pricing services retained by the Series, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Trust under the general supervision by the Board of Trustees of the Trust. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. Generally, trading in foreign securities, as well as U.S. government securities, money market instruments and certain fixed income securities, is substantially completed each day at various times prior to the close of business on the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net assets of the Series are determined as of such times. Foreign - -------------------------------------------------------------------------------- 59 MASTER SMALL CAP INDEX SERIES NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- currency exchange rates also are generally determined prior to the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of the Series' net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities may be valued at their fair value as determined in good faith by the Board of Trustees of the Trust or by the Investment Adviser using a pricing service and/or procedures approved by the Board of Trustees of the Trust. (b) Derivative Financial Instruments The Series may engage in various portfolio investment strategies both to increase the return of the Series and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. - Financial futures contracts - The Series may purchase or sell financial futures contracts and options on such futures contracts. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specified price or yield. Upon entering into a contract, the Series deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Series agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Series as unrealized gains or losses. When the contract is closed, the Series records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. - Options - The Series may purchase and write call and put options. When the Series writes an option, an amount equal to the premium received by the Series is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Series enters into a closing transaction), the Series realizes a gain or loss on the option to the extent of the premiums received or paid (or a gain or loss to the extent that the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. (c) Income Taxes The Series is classified as a partnership for federal income tax purposes. As such, each investor in the Series is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Series. Therefore, no federal income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. It is intended that the Series' assets will be managed so an investor in the Series can satisfy the requirements of Subchapter M of the Internal Revenue Code. - -------------------------------------------------------------------------------- 60 MASTER SMALL CAP INDEX SERIES NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- (d) Security Transactions and Investment Income Security transactions are accounted for on the date the securities are purchased or sold (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. (e) Securities Lending The Series may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Series and any additional required collateral is delivered to the Series on the next business day. Where the Series receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Series typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Series receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Series may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Series could experience delays and costs in gaining access to the collateral. The Series also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral. 2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES: The Trust has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. FAM is responsible for the management of the Series' portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Series. For such services, the Series pays a monthly fee at an annual rate of .01% of the average daily value of the Series' net assets. FAM has entered into a contractual arrangement with the Series under which all expenses incurred by the Series will not exceed .08%. This arrangement has a one-year term and is renewable. FAM reimbursed the Series for the amount of $32,038. Merrill Lynch Trust Company ("MLTC"), an indirect, wholly-owned subsidiary of ML & Co., is the Series' custodian. The Trust has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, or its affiliates. As of December 31, 2005, the Series lent securities with a value of $127,122 to MLPF&S or its affiliates. Pursuant to that order, the Trust also has retained Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. MLIM, LLC may, on behalf of the Trust and the Series, invest cash collateral received by the Series for such - -------------------------------------------------------------------------------- 61 MASTER SMALL CAP INDEX SERIES NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- loans, among other things, in a private investment company managed by MLIM, LLC or in registered money market funds advised by FAM or its affiliates. For the year ended December 31, 2005, MLIM, LLC received $90,653 in securities lending agent fees from the Series. For the year ended December 31, 2005, the Series reimbursed FAM $8,536 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, MLTC, ML & Co., and/or MLIM, LLC. 3. INVESTMENTS: Purchases and sales of investments, excluding short-term securities, for the year ended December 31, 2005 were $131,186,567 and $130,499,691, respectively. 4. SHORT-TERM BORROWINGS: The Trust, on behalf of the Series, along with certain other funds managed by FAM and its affiliates, is a party to a $500,000,000 credit agreement with a group of lenders. The Series may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Series may borrow up to the maximum amount allowable under the Series' current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Series pays a commitment fee of .07% per annum based on the Series' pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Series' election, the federal funds rate plus .50% or a base rate as defined in the credit agreement. The Series did not borrow under the credit agreement during the year ended December 31, 2005. On November 23, 2005 the credit agreement was renewed for one year under substantially the same terms. - -------------------------------------------------------------------------------- 62 MASTER SMALL CAP INDEX SERIES REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM December 31, 2005 - -------------------------------------------------------------------------------- To the Investors and Board of Trustees of Quantitative Master Series Trust: We have audited the accompanying statement of assets and liabilities, including the summary schedule of investments, of Master Small Cap Index Series, one of the portfolios constituting Quantitative Master Series Trust (the "Trust") as of December 31, 2005, and the related statement of operations for the year then ended, the statements 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 Trust'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. The Fund is not required to have, nor were we engaged to perform, an audit of its 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 Trust'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, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Master Small Cap Index Series of the Quantitative Master Series Trust as of December 31, 2005, 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 its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

SIGNIFICANT ACCOUNTING POLICIES: Master International Index Series (the "Series"), a non-diversified investment company, is part of Quantitative Master Series Trust (the "Trust"). The Trust is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interests in the Series, subject to certain limitations. The Series' financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The following is a summary of significant accounting policies followed by the Series. (a) Valuation of Investments Equity securities that are held by the Series that are traded on stock exchanges or the Nasdaq National Market are valued at the last sale price or official close price on the exchange, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Trust. Long positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Trust. Short positions traded in the OTC market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written are valued at the last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last asked price. Options purchased are valued at their last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last bid price. Swap agreements and forward foreign exchange contracts are valued daily based upon quoted fair valuations received daily by the Fund from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless the Investment Adviser believes that this method no longer produces fair valuations. Repurchase agreements are valued at cost plus accrued interest. The Series employs pricing services to provide certain securities prices for the Series. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Trust, including valuations furnished by the pricing services retained by the Series, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Series under the general supervision of the Trust's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. Generally, trading in foreign securities, as well as U.S. government securities and money market instruments, is substantially completed each day at various times prior to the close of business on the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net assets of the Portfolio are determined as of such times. Foreign currency exchange rates also are generally determined prior to the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are - -------------------------------------------------------------------------------- 78 MASTER INTERNATIONAL INDEX SERIES NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- determined and the close of business on the NYSE that may not be reflected in the computation of the Series' net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities may be valued at their fair value as determined in good faith by the Trust's Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Trust's Board of Trustees. (b) Derivative Financial Instruments The Series may engage in various portfolio investment strategies to provide liquidity or as a proxy for a direct investment in securities underlying the Series' index. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. - Financial futures contracts - The Series may purchase or sell financial futures contracts and options on such futures contracts. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Series deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Series agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Series as unrealized gains or losses. When the contract is closed, the Series records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. - Options - The Series may purchase and write call and put options. When the Series writes an option, an amount equal to the premium received by the Series is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Series enters into a closing transaction), the Series realizes a gain or loss on the option to the extent of the premiums received or paid (or a gain or loss to the extent that the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. - Forward foreign exchange contracts - The Series may enter into forward foreign exchange contracts as a hedge against either specific transactions or portfolio positions. The contract is marked-to-market daily and the change in market value is recorded by the Series as an unrealized gain or loss. When the contract is closed, the Series records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. - Foreign currency options and futures - The Series may also purchase or sell listed or over-the-counter foreign currency options, foreign currency futures and related options on foreign currency futures as a short or long hedge against possible variations in foreign exchange rates. Such transactions may be effected with respect to hedges on non-U.S. dollar-denominated securities owned by the Series, sold by the Series but not yet delivered, or committed or anticipated to be purchased by the Series. - -------------------------------------------------------------------------------- 79 MASTER INTERNATIONAL INDEX SERIES NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- (c) Foreign Currency Transactions Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets or liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Series invests in foreign securities, which may involve a number of risk factors and special considerations, not present with investments in securities of U.S. corporations. (d) Income Taxes The Series is classified as a partnership for federal income tax purposes. As such, each investor in the Series is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Series. Therefore, no federal income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. It is intended that the Series' assets will be managed so an investor in the Series can satisfy the requirements of Subchapter M of the Internal Revenue Code. (e) Security Transactions And Investment Income Security transactions are accounted for on the date the securities are purchased or sold (the trade dates).Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Series has determined the ex-dividend date. Interest income is recognized on the accrual basis. (f) Securities Lending The Series may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Series and any additional required collateral is delivered to the Series on the next business day. Where the Series receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Series typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Series receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Series may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Series also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral. - -------------------------------------------------------------------------------- 80 MASTER INTERNATIONAL INDEX SERIES NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- 2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES: The Trust has entered into an Investment Advisory Agreement with Fund Asset Management, L.P.("FAM").

FAM is responsible for the management of the Series' portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Series. For such services, the Series pays a monthly fee at an annual rate of .01% of the average daily value of the Series' net assets. FAM has entered into a contractual arrangement with the Series under which the expenses incurred by the Series will not exceed .12%. This arrangement has a one-year term and is renewable. For the year ended December 31, 2005, FAM reimbursed the Series in the amount of $13,001. For the year ended December 31, 2005, the Series reimbursed FAM $9,236 for certain accounting services. Certain officers and/or trustees of the Series are officers and/or directors of FAM, PSI, and/or ML & Co. 3. INVESTMENTS: Purchases and sales of investments, excluding short-term securities, for the year ended December 31, 2005 were $170,663,540 and $45,344,153, respectively. 4. COMMITMENTS: At December 31, 2005, the Series had entered into foreign exchange contracts, in addition to the contracts listed in the Schedule of Investments, under which it had agreed to sell a foreign currency with an approximate value of $64,000. 5. SHORT-TERM BORROWINGS: The Trust, on behalf of the Series, along with certain other funds managed by FAM and its affiliates, is a party to a $500,000,000 credit agreement with a group of lenders. The Series may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Series may borrow up to the maximum amount allowable under the Series current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Series pays a commitment fee of .07% per annum based on the Series pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Series election, the federal funds rate plus .50% or a base rate as defined in the credit agreement. The Series did not borrow under the credit agreement during the year ended December 31, 2005. On November 23, 2005, the credit agreement was renewed for one year under substantially the same terms. - -------------------------------------------------------------------------------- 81 MASTER INTERNATIONAL INDEX SERIES REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM December 31, 2005 - -------------------------------------------------------------------------------- To the Investors and Board of Trustees of Quantitative Master Series Trust: We have audited the accompanying statement of assets and liabilities, including the summary schedule of investments, of Master International Index Series, one of the portfolios constituting the Quantitative Master Series Trust (the "Trust") as of December 31, 2005, and the related statement of operations for the year then ended, the statements 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 Trust'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. The Trust is not required to have, nor were we engaged to perform, an audit of its 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 Trust'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, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Master International Index Series of the Quantitative Master Series Trust as of December 31, 2005, 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 its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

American Beacon Funds December 31, 2005 (BILL QUINN PHOTO) FELLOW SHAREHOLDERS: Enclosed please find the Annual Report for the American Beacon Treasury Inflation Protected Securities Fund for the year ended December 31, 2005. The year started with a short-term interest rate of 2.25%; however, the Federal Reserve Board subsequently raised the rate several times throughout the year resulting in a Fed Funds target rate of 4.25% at year end. As the year concluded, the Federal Open Market Committee indicated that it no longer sees monetary policy as "accommodative." In its December statement, the Fed reflected that inflation remained contained but that "some further measured policy firming is likely to be needed to keep the risks to the attainment of both sustainable economic growth and price stability roughly in balance." Although there is much debate as to the proper definition of "some," one thing is clear -- the Fed is nearing the end of its tightening cycle. Rising interest rates offset coupon rates to some extent, resulting in modest but positive returns. The American Beacon Treasury Inflation Protected Securities Fund realized a return of 1.86% for the twelve-month period. Looking forward, the Treasury Inflation Protected Securities Fund will continue to seek inflation protection and income by investing primarily in inflation-indexed debt securities. Please review the enclosed portfolio listings and detailed financial data. As always, we welcome the opportunity to serve your financial needs. Should you have any questions about the enclosed information, please do not hesitate to contact us at 800-967-9009. You may also access Fund and account information at www.americanbeaconfunds.com. Thank you for your continued confidence in the American Beacon Funds. Sincerely, (/s/ WILLIAM F. QUINN) William F. Quinn President, American Beacon Funds 1 MARKET OVERVIEW (Unaudited) - -------------------------------------------------------------------------------- The U.S. economy proved resilient in 2005 despite Hurricane Katrina, higher energy prices, worries about a housing bubble, and eight Fed rate hikes. Employment trends remained supportive, personal consumption continued as the engine of growth, and important measures of industrial production, and capacity utilization all displayed strength throughout the course of the year. The FOMC continued to remove policy accommodation at a "measured" pace and ended the year with a more neutral policy stance. Headline inflation, as measured by year- over-year CPI, surprised the market to the upside in 2005. In September, the CPI recorded a 4.7% increase before receding to 3.5% in December. Although energy prices continued to be the primary source of volatility in most headline measures of inflation, core prices were much more contained at 2.1% in December. Treasury inflation protected securities (TIPS) once again proved to be an important part of the fixed income landscape in 2005, as evidenced by the more than $60 billion of new issuance and a total market value that is approaching $350 billion. Many factors contributed to the volatility of the TIPS market in 2005, but it was primarily driven by firm energy prices and the Fed. At times, TIPS were heavily influenced by the directionality of energy market movements. This correlation was responsible for some of the volatility in inflation expectations and temporary spikes in breakeven inflation rates (the yield differential between conventional Treasuries and TIPS), especially at the front end of the TIPS curve. As the Fed continued on its tightening path, the market gradually lowered its inflation expectations by the end of the year. The general level of break-even rates finished the year approximately 10-15 basis points (0.10%-0.15%) below where they ended in 2004. Reflecting movements in the nominal bond markets, the TIPS yield curve flattened to the point of inversion in 2005. The spread between 5-year TIPS and 10-year TIPS flattened 58 basis points (0.58%) while the full curve (2-year to 28-year) flattened by more than 213 basis points (2.13%). As the year ended, 5-year, 10-year, and 28-year TIPS were yielding 2.08%, 2.06%, and 1.90% respectively. Although real yields on average increased by 40 basis points (0.40%), price losses on TIPS were more than offset by coupon income and the inflation accrual. For the full year of 2005, the Lehman U.S. TIPS Index returned 2.84%. Intermediate TIPS, as measured by the Lehman 1-10 Year TIPS Index, delivered a return for the year of 1.88%. Falling break-even inflation rates led to TIPS underperformance against their nominal Treasury counterparts by approximately 1.36%. 2 PERFORMANCE OVERVIEW AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- The Institutional Class of the Fund returned 1.86% for the twelve months ended December 31, 2005, falling slightly short of the Lehman Brothers 1-10 Yr. U.S. TIPS Index (the "Index") return of 1.88%. The Fund trailed the Lipper TIPS Index return of 2.73% for the same time period. The Fund underperformed the Index for the year by 2 basis points. All of the underperformance can be attributed to Fund expenses. Before the impact of Fund expenses, the Fund modestly outperformed the Index. Three strategies in place at various times during the year added most of the value in 2005. First, the Fund maintained a small allocation to nominal bonds as break-even rates narrowed. Second, it reduced its exposure to areas of the yield curve where new supply was auctioned. Finally, it established small positions in foreign inflation linked debt fully hedged to the U.S. dollar. The Fund remains focused on investing primarily in Treasury inflation protected securities to provide inflation protection and income to its shareholders.

The Fund's portfolio is actively managed, and its portfolio composition, credit quality breakdown, and other portfolio characteristics will vary from time to time. U.S. Treasury Inflation Protected Securities are unrated, but are backed by the full faith and credit of the government of the United States of America and are therefore considered by the Fund's investment advisor to be comparable to bonds rated AAA/Aaa. FUND EXPENSE EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees, administrative service fees, and other Fund expenses. The examples below are intended to help you understand the ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period from July 1, 2005 through December 31, 2005. ACTUAL EXPENSES The "Actual" lines of the table provide information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the first line under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Shareholders of the Institutional Class that invest in the Fund through an IRA may be subject to a custodial IRA fee of $12 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $12 higher. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The "Hypothetical" lines of the table provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed 5% per year rate of return before expenses (not the Fund's actual return). You may compare the ongoing costs of investing in the Fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. Shareholders of the Institutional Class that invest in the Fund through an IRA may be subject to a custodial IRA fee of $12 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $12 higher. 4 PERFORMANCE OVERVIEW AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND -- CONTINUED December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs charged by the Fund. Similarly, the expense examples for other funds do not reflect any transaction costs charged by those funds, such as sales charges (loads), redemption fees or exchange fees. Therefore, the "Hypothetical" lines of the table are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If you were subject to any transaction costs during the period, your costs would have been higher. BEGINNING ENDING EXPENSES PAID ACCOUNT ACCOUNT DURING PERIOD* VALUE VALUE 7/1/05- 7/1/05 12/31/05 12/31/05 --------- --------- -------------- INSTITUTIONAL CLASS Actual $1,000.00 $1,002.11 $2.08 Hypothetical (5% return before expenses) $1,000.00 $1,023.13 $2.10 * Expenses are equal to the Fund's annualized expense ratio for the six-month period of 0.41%, multiplied by the average account value over the period, multiplied by the number derived by dividing the number of days in the most recent fiscal half-year (184) by days in the year (365) to reflect the half-year period. 5 AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- The Board of Trustees and Shareholders of American Beacon Treasury Inflation Protected Securities Fund We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the American Beacon Treasury Inflation Protected Securities Fund (the "Fund") (formerly known as the American AAdvantage Treasury Inflation Protected Securities Fund), a separate fund comprising the American Beacon Funds, (formerly known as the American AAdvantage Funds) as of December 31, 2005, and the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audit 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 Fund'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 Fund'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, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audit provides 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 American Beacon Treasury Inflation Protected Securities Fund at December 31, 2005, 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. -s- ERNST & YOUNG LLP Chicago, Illinois February 21, 2006 6 AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND SCHEDULE OF INVESTMENTS December 31, 2005 - -------------------------------------------------------------------------------- <Table> PAR AMOUNT VALUE ----------- -------- (DOLLARS IN THOUSANDS) U.S. GOVERNMENT SPONSORED AGENCY INSTRUMENTS - 0.65% Federal Home Loan Bank, 7.507%, Due 2/20/2007............... $ 100 $ 101 Federal National Mortgage Association, 5.83%, Due 2/17/2009................................................. 100 97 ------- TOTAL U.S. GOVERNMENT SPONSORED AGENCY INSTRUMENTS...... 198 ------- U.S. GOVERNMENT SECURITIES - 95.64% U.S. Treasury Inflation-Indexed Notes, 0.875%, Due 4/15/2010..................................... 3,853 3,663 1.625%, Due 1/15/2015..................................... 1,455 1,402 1.875%, Due 7/15/2013..................................... 4,550 4,487 1.875%, Due 7/15/2015..................................... 737 725 2.00%, Due 1/15/2014...................................... 2,145 2,133 2.00%, Due 7/15/2014...................................... 2,050 2,039 3.00%, Due 7/15/2012...................................... 2,858 3,022 3.375%, Due 1/15/2007..................................... 949 956 3.375%, Due 1/15/2012..................................... 1,907 2,051 3.50%, Due 1/15/2011...................................... 2,403 2,569 3.625%, Due 1/15/2008..................................... 425 437 3.875%, Due 1/15/2009..................................... 3,716 3,906 4.25%, Due 1/15/2010...................................... 1,125 1,219 U.S. Treasury Notes, 4.25%, Due 8/15/2015...................................... 650 642 ------- TOTAL U.S. GOVERNMENT SECURITIES........................ 29,251 ------- VARIABLE RATE CORPORATE OBLIGATIONS - 1.05% (NOTE B) FINANCIAL - 1.05% Allstate Life Global Funding, 5.74%, Due 3/1/2010........... 100 95 Lehman Brothers Holdings, Incorporated, 5.62%, Due 6/2/2009.................................................. 80 77 SLM Corporation, 6.81%, Due 1/31/2014....................... 150 148 ------- TOTAL FINANCIAL......................................... 320 ------- TOTAL VARIABLE RATE CORPORATE OBLIGATIONS............... 320 ------- SHORT TERM INVESTMENTS - 3.50% SHARES ---------- American Beacon Money Market Select Fund (Note A)........... 1,071,309 $ 1,071 ------- TOTAL SHORT TERM INVESTMENTS............................ 1,071 ------- TOTAL INVESTMENTS - 100.84% (COST $31,441).................. 30,840 ------- LIABILITIES, NET OF OTHER ASSETS - (0.84%)..................

See accompanying notes - -------------------------------------------------------------------------------- 10 AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND NOTES TO FINANCIAL STATEMENTS December 31, 2005 - -------------------------------------------------------------------------------- 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES American Beacon Funds (the "Trust"), formerly known as the American AAdvantage Funds, is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as a diversified, no load, open-end management investment company. The American Beacon Treasury Inflation Protected Securities Fund (the "Fund") is a series of the Trust and commenced active operations on June 30, 2004. The Fund's investment objective is to provide inflation protection and income. American Beacon Advisors, Inc. (the "Manager"), formerly known as AMR Investment Services, Inc., is a wholly-owned subsidiary of AMR Corporation, the parent company of American Airlines, Inc. ("American"), and was organized in 1986 to provide business management, advisory, administrative and asset management consulting services to the Trust and other investors. The following is a summary of the significant accounting policies followed by the Fund. Security Valuation Net asset value per share is calculated as of the close of business on the New York Stock Exchange, normally 4:00 p.m. Eastern Time. Debt securities (other than short-term securities) normally are valued on the basis of prices provided by a pricing service and may take into account appropriate factors such as institution-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data. In some cases, the prices of debt securities may be determined using quotes obtained from brokers. Investments in mutual funds are valued at the closing net asset value per share of the mutual fund on the day of valuation. Investment grade short-term obligations with 60 days or less to maturity are valued using the amortized cost method. Securities for which the market prices are not readily available or are not reflective of the fair value of the security, will be priced at a fair value following procedures approved by the Board of Trustees (the "Board"). Issuer specific events, market trends, valuations of similar securities and other market data may be reviewed in the course of making a good faith determination of a security's fair value. In light of the judgement involved in fair value decisions, there can be no assurance that a fair value assigned to a particular security is accurate. Security Transactions and Investment Income Security transactions are recorded on the trade date of the security purchase or sale. Dividend income is recorded on the ex-dividend date. Interest income is earned from settlement date, recorded on an accrual basis, and adjusted, if necessary, for accretion of discounts and amortization of premiums. For financial and tax reporting purposes, realized gains and losses are determined on the basis of specific lot identification. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted to the rate of inflation. Interest is accrued based on the principal value, which is adjusted for inflation. Any increase in the principal amount of an inflation-indexed bond is recorded as interest income, even though principal is not received until maturity. - -------------------------------------------------------------------------------- 11 AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- Dividends to Shareholders From January 1, 2005 through February 28, 2005, the Fund declared dividends from net investment income daily, payable monthly. Beginning March 1, 2005, the Fund declares and pays dividends from net investment income quarterly. Distributions, if any, of net realized capital gains are generally paid annually and recorded on the ex-dividend date. Currency Translation All assets and liabilities initially expressed in foreign currency values are converted into U.S. dollar values at the mean of the bid and ask prices of such currencies against U.S. dollars as last quoted by a recognized dealer. Income, expenses and purchases and sales of investments are translated into U.S. dollars at the rate of exchange prevailing on the respective dates of such transactions. The effect of changes in foreign currency exchange rates on investments is separately identified from the fluctuations arising from changes in market values of securities held and is reported with all other foreign currency gains and losses in the Fund's Statement of Operations. Forward Foreign Currency Exchange Contracts The Fund may enter into forward foreign currency contracts to hedge the exchange rate risk on investment transactions or to hedge the value of Fund securities denominated in foreign currencies. Forward foreign currency contracts are valued at the forward exchange rate prevailing on the day of valuation. The Fund bears the market risk that arises from changes in foreign exchange rates, and accordingly, the unrealized gain (loss) on these contracts is reflected in the accompanying financial statements. The Fund also bears the credit risk if the counterparty fails to perform under the contract. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from those estimated. Other Under the Trust's organizational documents, its officers and directors are indemnified against certain liability arising out of the performance of their duties to the Trust. In the normal course of business, the Trust enters into contracts that provide indemnification to the other party or parties against potential costs or liabilities. The Trust's maximum exposure under these arrangements is dependent on claims that may be made in the future and, therefore, cannot be estimated. The Trust has had no prior claims or losses pursuant to any such agreement. 2. TRANSACTIONS WITH AFFILIATES Management Agreement The Trust and the Manager are parties to a Management Agreement that obligates the Manager to provide or oversee the provision of all administrative, investment advisory, fund management and securities lending services. Investment assets of the Fund are managed by multiple investment - -------------------------------------------------------------------------------- 12 AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- advisors that have entered into separate investment advisory agreements with the Manager. As compensation for performing the duties required under the Management Agreement, the Manager receives from the Fund an annualized fee equal to 0.10% of the Fund's average daily net assets plus amounts paid by the Manager to the investment advisors of the Fund. During the year ended December 31, 2005, the management fee range, including fees paid to investment advisors, was from 0.15% to 0.25%, depending upon assets under management. Total management fees were $60,555, of which $31,940 was paid to investment advisors and $28,615 was retained by the Manager. Administrative Services Agreement The Manager and the Trust entered into an Administrative Services Agreement that obligates the Manager to provide or oversee administrative and management services to the Fund. As compensation for performing the duties required under the Administrative Services Agreement, the Manager receives an annualized fee of 0.10% of the average daily net assets of the Fund. Investment in Affiliated Fund The Fund may invest in the American Beacon Money Market Select Fund (the "Select Fund"). The Manager serves as investment advisor to the Select Fund and receives from the Select Fund an annualized fee equal to 0.10% of the Select Fund's average daily net assets. During the period, fees earned by the Manager from the Fund's investment in the Select Fund were $1,006. Other Certain officers or Trustees of the Trust are also current or former officers or employees of the Manager or American. The Trust makes no direct payments to its officers. Mr. Feld and the non-interested Trustees (other than Mr. O'Sullivan) and their spouses are provided unlimited air transportation on American. Retired Trustees and their spouses are provided free transportation on American, up to a maximum annual value of $40,000. The Trust compensates each Trustee with payments in an amount equal to the Trustee's income tax on the value of this free airline travel. Mr. O'Sullivan, as a retiree of American, already receives flight benefits. Mr. O'Sullivan receives an annual retainer of $40,000 plus $1,250 for each Board meeting attended. Reimbursement of Expenses The Manager contractually agreed to reimburse the Fund for a portion of its fees through February 28, 2006 to the extent total annual Fund operating expenses exceeded 0.46%. During the year ended December 31, 2005, the manager reimbursed the Fund $4,096. Expense Reimbursement Plan The Fund has adopted an expense reimbursement Plan whereby the Manager may seek recoupment of fees waived or expenses reimbursed for a period of up to three years. However, recoupment will only occur if the Funds' average net assets have grown or expenses have declined sufficiently to allow recoupment without causing its expense ratio to exceed the previously agreed upon contractual expense limit. During the year ended December 31, 2005, due to asset growth and - -------------------------------------------------------------------------------- 13 AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- a reduction of expenses in the latter part of the year, the Manager recouped $4,096 for expenses previously waived earlier in the year and $14,537 for expenses waived during 2004. Interfund Lending Program Pursuant to an Exemptive Order by the SEC, the Fund, along with other registered investment companies having management contracts with the Manager, may participate in an interfund lending program. This program provides an alternative credit facility allowing the Fund to borrow from, or lend money to, other participating Funds. The Fund did not utilize the credit facility during the year ended December 31, 2005. 3. FEDERAL INCOME AND EXCISE TAXES It is the policy of the Fund to comply with the requirements of Subchapter M of the Internal Revenue Code and to distribute substantially all net investment income as well as any net realized capital gains on the sale of investments. Therefore, no federal income tax provision is required. Dividends are determined in accordance with federal income tax regulations that may treat certain transactions differently than U.S. generally accepted accounting principles. Accordingly, the character of distributions and composition of net assets for tax purposes may differ from those reflected in the accompanying financial statements. The tax character of distributions during the years ended December 31, 2005 and December 31, 2004 were as follows (in thousands): <Table> YEAR ENDED YEAR ENDED DECEMBER 31, DECEMBER 31, 2005 2004 ------------ ------------ DISTRIBUTIONS PAID FROM: Ordinary income*............................................ $1,735 $406 * For tax purposes, short-term capital gains distributions are considered ordinary income distributions. For the year ended December 31, 2005, the components of distributable earnings were as follows (in thousands): Cost basis of investments for federal income tax purposes... $31,656 Unrealized appreciation..................................... 5 Unrealized depreciation..................................... (821) ------- Net unrealized appreciation (depreciation).................. (816) Undistributed ordinary income............................... 26 Undistributed long-term gain (loss)......................... (144) ------- Distributable earnings...................................... $ (934) ======= Financial reporting records are adjusted for permanent book/tax differences to reflect tax character. Financial records are not adjusted for temporary differences. The temporary differences between financial reporting and tax-basis reporting of unrealized appreciation/(depreciation) are attributable primarily to the tax deferral of wash sales and current recognition of unrealized appreciation/(depreciation) on open foreign currency transactions. </Table> - -------------------------------------------------------------------------------- 14 AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- Due to the inherent differences in the recognition of income, expenses and realized gains/ (losses) under U.S. generally accepted accounting principles and federal income tax regulations, permanent differences between book and tax reporting have been identified and appropriately reclassified on the Statement of Assets and Liabilities without impacting the net assets of the Fund. These differences are due primarily to the recognition of certain foreign currency gains/(losses) as ordinary income for tax purposes. Accordingly, the following amounts represent current year permanent differences that have been reclassified as of December 31, 2005 (in thousands): Paid-in-capital............................................. $ -- Undistributed net investment income......................... 52 Accumulated net realized gain (loss)........................ (52) Unrealized appreciation (depreciation) of investments, futures contracts and foreign currency.................... -- At December 31, 2005, the Fund had a capital loss carryover of $144,311 expiring in 2013. Net capital and foreign currency losses incurred after October 31, 2005 and within the taxable year are deemed to arise on the first business day of the Fund's next taxable year. For the period ended December 31, 2005, the Fund deferred $120,015 of capital losses to January 1, 2006. 4. INVESTMENT TRANSACTIONS Purchases and redemptions of investments for the year ended December 31, 2005, excluding short-term investments, were $107,890,850 and $98,011,957, respectively. The Fund had purchases and sales of U.S. government securities of $106,150,983 and $95,889,471, respectively.

American Beacon Funds December 31, 2005 (BILL QUINN PHOTO) FELLOW SHAREHOLDERS: Enclosed please find the Annual Report for the American Beacon Funds for the year ended December 31, 2005. During this time, the money market series of the American Beacon Funds performed well against their respective peer groups. The year started with a short-term interest rate of 2.25%; however, the Federal Reserve Board subsequently raised the rate several times throughout the year resulting in a Fed Funds target rate of 4.25% at year end. As the year concluded, the Federal Open Market Committee (FOMC) indicated that it no longer sees monetary policy as "accommodative." In its December statement, the Fed reflected that inflation remained contained but that "some further measured policy firming is likely to be needed to keep the risks to the attainment of both sustainable economic growth and price stability roughly in balance." Although there is much debate as to the proper definition of "some," one thing is clear -- the Fed is nearing the end of its tightening cycle. Despite rising interest rates, the Cash Management Class of the American Beacon Funds produced strong relative returns for the period. The Money Market Fund-Cash Management Class returned 3.19% for the twelve months, outperforming the Lipper Institutional Money Market Average return of 2.84%. The U.S. Government Money Market Fund -- Cash Management Class outpaced the Lipper Institutional U.S. Government Money Market Average with a return of 3.12% versus 2.85% for the Average. Both Funds surpassed their respective Lipper peer groups over all time periods. Looking forward, the market is pricing in a 100% chance of a 0.25% increase at the January 31st FOMC meeting; however, the likelihood of additional increases at the March and/or May meetings are less certain. Rather than simply having a conviction that the Fed Funds rate is too low, the FOMC now appears to be entering into a phase where future rate hikes will hinge more on economic data developments. We will continue to monitor economic trends and will adjust the Funds' characteristics accordingly. Additionally, we expect to remain conservative on credit risk given the tight credit spread environment. Please review the enclosed portfolio listings and detailed financial data. As always, we welcome the opportunity to serve your financial needs. Should you have any questions about the enclosed information, please do not hesitate to contact us at 800-967-9009.

Quinn President, American Beacon Funds 1 ECONOMIC OVERVIEW (Unaudited) - -------------------------------------------------------------------------------- The year began with the U.S. economy growing at a solid pace as first quarter gross domestic product (GDP) came in at a strong 3.8%. GDP continued to show solid growth at a 3.3% annual rate during the second quarter and 4.1% annual rate during the third quarter, fueled by robust consumer spending and home building. However, late in the third quarter, hurricanes Katrina and Rita blew ashore, leaving wind, rain, and economic uncertainty in their wake. Crude oil prices, already trading in the mid $60 range before the hurricanes, hit a high of $70 per barrel on September 1st. These surging fuel costs dampened consumer sentiment, causing concerns of reduced consumer spending and lower corporate profit margins. As a result, fourth quarter GDP growth did not fare as well. Economists had expected fourth quarter GDP growth would slow as a result of reduced discounts from automakers and moderating home sales. In addition, rising home-heating costs threatened to dampen consumer spending. The consensus estimate of 2.8% GDP growth missed the mark as the initial estimate of fourth quarter GDP came in at 1.1%, raising questions as to the strength of the economy. However, fiscal spending is expected to spur economic growth during the first half of 2006 as the government works to rebuild areas impacted by the hurricanes. On the employment front, nonfarm payroll growth showed some volatility in 2005. However, the monthly average jobs created during the year came in at a respectable 165,000. In addition, the unemployment rate hit 4.9% in August before backing up to 5.1% in September due to job losses from the hurricanes. This drop in jobs was much less than economists had forecasted, suggesting that underlying job growth during this time remained strong. Labor market conditions continued to improve as U.S. employers added over 500,000 new jobs during the fourth quarter and the unemployment rate dropped back to its pre-hurricane level of 4.9%. Business activity also remained strong as the U.S. services sector, which makes up almost 90% of the U.S. economy, expanded for the thirty-third consecutive month. Despite talk of a pause in the aftermath of Katrina and Rita, the Federal Open Market Committee (FOMC) continued to raise overnight rates by 25 basis points at each of their remaining meetings for the year. This made it a total of eight 25 basis point tightenings during 2005, resulting in a Fed Funds target rate of 4.25% at year end. In addition, the "measured" policy adjustment language remained part of the Fed's statement throughout 2005. In the minutes of the September meeting, the Fed stated "upside risks to inflation appeared to have increased" and "further rate increases probably would be required." It was not until the December meeting that the Fed made reference to no longer seeing monetary policy as "accommodative." In its December statement, the Fed reflected that inflation remained contained but that "some further measured policy firming is likely to be needed to keep the risks to the attainment of both sustainable economic growth and price stability roughly in balance." Although there is much debate as to the proper definition of "some," it appears that the Fed is nearing the end of its tightening cycle. The actual number of rate hikes left, however, will ultimately be determined by future economic trends and inflation expectations. Though core consumer and wholesale inflation are running close to the Fed target level of 2%, high energy prices continue to drive up headline inflation numbers. So the question remains, will businesses begin to pass these elevated energy costs on to the consumer in the form of higher prices for goods and services? If so, the Fed can be expected to adjust future monetary policy accordingly. 2 PERFORMANCE OVERVIEW AMERICAN BEACON MONEY MARKET FUND(SM) December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- As the economy continued to show signs of strength throughout the year, the Fed maintained its stance of tightening monetary policy at a measured pace during all of 2005. In response, the American Beacon Money Market Fund's weighted-average maturity was maintained below 45 days throughout the year. The Fed raised the overnight target at each of the eight FOMC meetings in 2005, resulting in a 4.25% Fed Funds target by year end. This was a move of 25 basis points (0.25%) per meeting, after starting the year at 2.25%. The primary strategy of the Fund was to buy variable rate securities, short-dated commercial paper and overnight investments. Maintaining short duration in a rising interest rate environment resulted in the Fund outperforming its Lipper peer group. This strategy will stay in place until economic data suggest the Fed is about to end its current tightening cycle. For the twelve months ended December 31, 2005, the total return of the Cash Management Class of the American Beacon Money Market Fund was 3.19%. The Fund outperformed the Lipper Institutional Money Market Average return of 2.84% by 35 basis points. Lipper Inc. ranked the Cash Management Class of the Fund 18th among 303 and 17th among 262 Institutional Money Market Funds for the one-year and three-years ended December 31, 2005, respectively(1). The Lipper Institutional Money Market Average is calculated by taking an arithmetic average of the returns of the mutual funds in the Lipper Institutional Money Market Funds category. Lipper is an independent mutual fund research and ranking service that ranks mutual funds in various categories by making comparative calculations using total returns.

Fund performance in the table above does not reflect the deduction of taxes a shareholder would pay on distributions or the redemption of shares. 2 Fund performance for the five and ten-year periods represents the total returns achieved by the Institutional Class from 1/1/96 up to 12/1/01, the inception date of the Cash Management Class and the returns of the Cash Management Class since its inception. Expenses of the Cash Management Class are lower than those of the Institutional Class. Therefore, total returns shown are lower than they would have been had the Cash Management Class been in place since 1/1/96. 3 PERFORMANCE OVERVIEW AMERICAN BEACON MONEY MARKET FUND(SM) -- CONTINUED December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- PORTFOLIO STATISTICS AS OF DECEMBER 31, 2005 <Table> <Caption> CASH MANAGEMENT INSTITUTIONAL PLANAHEAD PLATINUM CLASS CLASS CLASS CLASS ---------- ------------- --------- -------- 7-day Current Yield* 4.20% 4.00% 3.77% 3.36% 7-day Effective Yield* 4.29% 4.08% 3.85% 3.42% 30-day Yield* 4.11% 3.93% 3.70% 3.27% Weighted Average Maturity 35 Days 35 Days 35 Days 35 Days Moody's Rating Aaa N/A N/A N/A S&P Rating AAAm N/A N/A N/A </Table> * Annualized.

FUND EXPENSE EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees, administrative service fees, and other Fund expenses. The examples below are intended to help you understand the ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period in each Class and held for the entire period from July 1, 2005 through December 31, 2005. ACTUAL EXPENSES The "Actual" lines of the table provide information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the first line under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Shareholders of the PlanAhead Class that invest in the Fund through an IRA may be subject to a custodial IRA fee of $12 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $12 higher. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The "Hypothetical" lines of the table provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed 5% per year rate of return before expenses (not the Fund's actual return). You may compare the ongoing costs of investing in the Fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. Shareholders of the PlanAhead Class that invest in the Fund through an IRA may be subject to 4 PERFORMANCE OVERVIEW AMERICAN BEACON MONEY MARKET FUND(SM) -- CONTINUED December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- a custodial IRA fee of $12 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $12 higher. You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs charged by the Fund. Similarly, the expense examples for other funds do not reflect any transaction costs charged by those funds, such as sales charges (loads), redemption fees or exchange fees. Therefore, the "Hypothetical" lines of the table are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If you were subject to any transaction costs during the period, your costs would have been higher. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT ACCOUNT DURING PERIOD* VALUE VALUE 7/1/05- 7/1/05 12/31/05 12/31/05 --------- --------- -------------- CASH MANAGEMENT CLASS Actual $1,000.00 $1,018.49 $0.76 Hypothetical (5% return before expenses) $1,000.00 $1,024.45 $0.76 INSTITUTIONAL CLASS Actual $1,000.00 $1,017.77 $1.47 Hypothetical (5% return before expenses) $1,000.00 $1,023.75 $1.48 PLANAHEAD CLASS Actual $1,000.00 $1,016.57 $2.67 Hypothetical (5% return before expenses) $1,000.00 $1,022.56 $2.68 PLATINUM CLASS Actual $1,000.00 $1,014.20 $5.03 Hypothetical (5% return before expenses) $1,000.00 $1,020.22 $5.04 </Table> * Expenses are equal to the Fund's annualized expense ratios for the six-month period of 0.15%, 0.29%, 0.52%, and 0.99% for the Cash Management, Institutional, PlanAhead, and Platinum Classes, respectively, multiplied by the average account value over the period, multiplied by the number derived by dividing the number of days in the most recent fiscal half-year (184) by days in the year (365) to reflect the half-year period. 5 PERFORMANCE OVERVIEW AMERICAN BEACON U.S. GOVERNMENT MONEY MARKET FUND(SM) December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- With the Fed maintaining its policy of raising the Fed Funds target at a measured pace during 2005, the American Beacon U.S. Government Money Market Fund's weighted-average maturity was maintained below 20 days throughout the year. The Fed raised the overnight target at each of the eight FOMC meetings in 2005, resulting in a 4.25% Fed Funds target by year end. This was a move of 25 basis points (0.25%) per meeting, after starting the year at 2.25%. The primary strategy of the Fund was to buy short-dated and variable rate agencies along with overnight repurchase agreements. Maintaining short duration in a rising interest rate environment resulted in the Fund outperforming its Lipper peer group. This strategy will stay in place until economic data suggest an end to the current tightening cycle. For the twelve months ended December 31, 2005, the total return of the Cash Management Class of the American Beacon U.S. Government Money Market Fund was 3.12%. The Fund outperformed the Lipper Institutional U.S. Government Money Market Average return of 2.85% by 27 basis points. Lipper Inc. ranked the Cash Management Class of the Fund 10th among 137, 11th among 102, and 12th among 61 Institutional U.S. Government Money Market Funds for the one-year, five-years and ten-years ended December 31, 2005, respectively(1). The Lipper Institutional U.S. Government Money Market Average is calculated by taking an arithmetic average of the returns of the mutual funds in the Lipper Institutional U.S. Government Money Market Funds category.

FUND EXPENSE EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees, administrative service fees, and other Fund expenses. The examples below are intended to help you understand the ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period in each Class and held for the entire period from July 1, 2005 through December 31, 2005. ACTUAL EXPENSES The "Actual" lines of the table provide information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the first line under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Shareholders of the PlanAhead Class that invest in the Fund through an IRA may be subject to a custodial IRA fee of $12 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $12 higher. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The "Hypothetical" lines of the table provide information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed 5% per year rate of return before expenses (not the Fund's actual return). You may compare the ongoing costs of investing in the Fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. Shareholders of the PlanAhead Class that invest in the Fund through an IRA may be subject to a custodial IRA fee of $12 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $12 higher. You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs charged by the Fund. Similarly, the expense examples for other funds do not reflect any transaction costs charged by those funds, such as sales charges (loads), redemption fees or exchange fees. Therefore, the "Hypothetical" lines of the table are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If you were subject to any transaction costs during the period, your costs would have been higher. 7 PERFORMANCE OVERVIEW AMERICAN BEACON U.S. GOVERNMENT MONEY MARKET FUND(SM) -- CONTINUED December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT ACCOUNT DURING PERIOD* VALUE VALUE 7/1/05- 7/1/05 12/31/05 12/31/05 --------- --------- -------------- CASH MANAGEMENT CLASS Actual $1,000.00 $1,018.17 $0.97 Hypothetical (5% return before expenses) $1,000.00 $1,024.25 $0.97 PLANAHEAD CLASS Actual $1,000.00 $1,015.94 $3.16 Hypothetical (5% return before expenses) $1,000.00 $1,022.07 $3.17 PLATINUM CLASS Actual $1,000.00 $1,014.08 $5.03 Hypothetical (5% return before expenses) $1,000.00 $1,020.21 $5.04 </Table> * Expenses are equal to the Fund's annualized expense ratios for the six-month period of 0.19%, 0.62%, and 0.99% for the Cash Management, PlanAhead, and Platinum Classes, respectively, multiplied by the average account value over the period, multiplied by the number derived by dividing the number of days in the most recent fiscal half-year (184) by days in the year (365) to reflect the half-year period. 8 PERFORMANCE OVERVIEW AMERICAN BEACON MUNICIPAL MONEY MARKET FUND(SM) December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- Given the rising interest rate environment of 2005, the investment manager to the American Beacon Municipal Money Market Fund targeted a shorter weighted-average maturity during the year. The Fund maintained a high concentration in daily and weekly variable rate demand notes (VRDNs) backed by either bond insurance or a bank letter of credit. The investment manager will continue to focus purchases on the VRDN market and may buy selective fixed rate instruments when evidence emerges that the Fed has completed its current tightening cycle. For the twelve months ended December 31, 2005, the total return of the PlanAhead Class of the American Beacon Municipal Money Market Fund was 1.49% as compared to the Lipper Tax-Exempt Money Market Average return of 1.76%. The Lipper Tax-Exempt Money Market Average is calculated by taking an arithmetic average of the returns of the mutual funds in the Lipper Tax-Exempt Money Market Funds category.

These financial statements and financial highlights are the responsibility of the Funds' 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 Funds' 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 Funds' 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. 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 American Beacon Funds at December 31, 2005, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. -s- ERNST & YOUNG LLP Chicago, Illinois February 21, 2006 - -------------------------------------------------------------------------------- 11 AMERICAN BEACON FUNDS STATEMENTS OF ASSETS AND LIABILITIES December 31, 2005 - -------------------------------------------------------------------------------- <Table> <Caption> U.S. GOVERNMENT MUNICIPAL MONEY MARKET MONEY MARKET MONEY MARKET ------------ --------------- ------------ (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) ASSETS: Investment in Portfolio, at value....................... $ 514,287 $ 28,427 $ 4,407 Receivable for fund shares sold......................... 18 -- -- Receivable from Manager for expense reimbursement (Note 2).................................................... 35 7 3 Prepaid expenses........................................ 19 18 11 ------------ ----------- ---------- TOTAL ASSETS........................................ 514,359 28,452 4,421 ------------ ----------- ---------- LIABILITIES: Payable for fund shares redeemed........................ 16 -- -- Dividends payable....................................... 298 60 -- Administrative service and service fees payable (Note 2).................................................... 111 3 2 Distribution fees payable (Note 2)...................... 10 1 -- Other liabilities....................................... 102 22 6 ------------ ----------- ---------- TOTAL LIABILITIES................................... 537 86 8 ------------ ----------- ---------- NET ASSETS.................................................. $ 513,822 $ 28,366 $ 4,413 ============ =========== ========== ANALYSIS OF NET ASSETS: Paid-in-capital......................................... 513,822 28,366 4,413 ------------ ----------- ---------- NET ASSETS.................................................. $ 513,822 $ 28,366 $ 4,413 ============ =========== ========== SHARES OUTSTANDING (NO PAR VALUE): Cash Management Class................................... 200,009,920 22,517,744 N/A ============ =========== ========== Institutional Class..................................... 36,421,050 N/A N/A ============ =========== ========== PlanAhead Class......................................... 236,903,527 1,933,180 1,646,524 ============ =========== ========== Platinum Class.......................................... 40,487,845 3,914,892 2,766,193 ============ =========== ========== NET ASSET VALUE PER SHARE, OFFERING AND REDEMPTION PRICE PER SHARE: Cash Management Class................................... $ 1.00 $ 1.00 N/A ============ =========== ========== Institutional Class..................................... $ 1.00 N/A N/A ============ =========== ========== PlanAhead Class......................................... $ 1.00 $ 1.00 $ 1.00 ============ =========== ========== Platinum Class.......................................... $ 1.00 $ 1.00 $ 1.00 ============ =========== ========== </Table> See accompanying notes - -------------------------------------------------------------------------------- 12 AMERICAN BEACON FUNDS STATEMENTS OF OPERATIONS Year Ended December 31, 2005 - -------------------------------------------------------------------------------- <Table> <Caption> U.S. GOVERNMENT MUNICIPAL MONEY MARKET MONEY MARKET MONEY MARKET ------------ --------------- ------------ (IN THOUSANDS) INVESTMENT INCOME ALLOCATED FROM PORTFOLIO: Interest income......................................... $22,982 $969 $160 Portfolio expenses......................................

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES American Beacon Funds (the "Trust"), formerly known as the American AAdvantage Funds, is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940 (the "Act"), as amended, as a diversified, no-load, open-end management investment company with separate series. The following series are included in this report: American Beacon Money Market, American Beacon U.S. Government Money Market and American Beacon Municipal Money Market Funds (each a "Fund" and collectively, the "Funds"). Each Fund invests all of its investable assets in the corresponding portfolio of the American Beacon Master Trust, an open-end diversified management investment company, as follows: <Table> <Caption> AMERICAN BEACON: AMERICAN BEACON MASTER TRUST: - ---------------- (RT ARROW) INVESTS ASSETS IN (RT ARROW) ----------------------------- Money Market Fund Money Market Portfolio U.S. Government Money Market Fund U.S. Government Money Market Portfolio Municipal Money Market Fund Municipal Money Market Portfolio </Table> Each Fund has the same investment objectives as its corresponding American Beacon Master Trust Portfolio. The value of such investment reflects each Fund's proportionate interest in the net assets of the corresponding portfolio (7.58%, 11.87% and 14.45% at December 31, 2005 of the American Beacon Master Trust Money Market, U.S. Government Money Market and Municipal Money Market Portfolios, respectively) (each a "Portfolio" and collectively the "Portfolios"). The financial statements of the Portfolios are included elsewhere in this report and should be read in conjunction with the Funds' financial statements. American Beacon Advisors, Inc. (the "Manager"), formerly known as AMR Investment Services, Inc., is a wholly-owned subsidiary of AMR Corporation, the parent company of American Airlines, Inc. ("American"), and was organized in 1986 to provide business management, advisory, administrative and asset management consulting services to the Trust and other investors. The following is a summary of the significant accounting policies followed by the Funds. Class Disclosure Each Fund has multiple classes of shares designed to meet the needs of different groups of investors. Please note that not all Funds offer all classes. The following table sets forth the differences amongst the classes: <Table> <Caption> CLASS OFFERED TO: SERVICE AND DISTRIBUTION FEES: - ----- ----------- ------------------------------ CASH MANAGEMENT CLASS Investors making an initial Administrative Service Fee -- 0.07% investment of $10 million for Money Market and $2 million for U.S. Government Money Market, or investors investing through an intermediary INSTITUTIONAL CLASS Investors making an initial Administrative Service Fee -- 0.10% investment of $2 million PLANAHEAD CLASS General public and investors Administrative Service Fee -- 0.10% investing through an intermediary Service Fee -- 0.25% PLATINUM CLASS Investors investing through selected Administrative Service Fee -- 0.65% financial institutions (such as banks Distribution Fee -- 0.25% and broker-dealers) </Table> - -------------------------------------------------------------------------------- 16 AMERICAN BEACON FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- Valuation of Investments The Funds record their investment in the Portfolios at fair value. Valuation of securities by the Portfolios is discussed in Note 1 of the Portfolios' Notes to Financial Statements, which are included elsewhere in this report. Investment Income and Dividends to Shareholders Each Fund records its share of net investment income (loss) and realized gain (loss) in the Portfolio each day. All net investment income (loss) and realized gain (loss) of each Portfolio are allocated pro rata among the corresponding Fund and other investors in each Portfolio at the time of such determination. The Funds generally declare dividends daily from net investment income and net short-term capital gain, if any, payable monthly. Dividends to shareholders are determined in accordance with federal income tax principles that may treat certain transactions differently than U.S. generally accepted accounting principles. Allocation of Income, Expenses, Gains and Losses Income, expenses (other than those attributable to a specific class), gains and losses are allocated daily to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class. Valuation of Shares The price per share is calculated separately for each class of each Fund on each day on which shares are offered for sale and orders accepted or upon receipt of a redemption request. With respect to a class of a Fund, price per share is computed by dividing the value of the class' pro rata allocation of the Fund's investments and other assets, less liabilities, by the number of class shares outstanding. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated. Other Under the Trust's organizational documents, its officers and directors are indemnified against certain liability arising out of the performance of their duties to the Trust. In the normal course of business, the Trust enters into contracts that provide indemnification to the other party or parties against potential costs or liabilities. The Trust's maximum exposure under these arrangements is dependent on claims that may be made in the future and, therefore, cannot be estimated. The Trust has had no prior claims or losses pursuant to any such agreement. - -------------------------------------------------------------------------------- 17 AMERICAN BEACON FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- 2. TRANSACTIONS WITH AFFILIATES Administrative Services Agreement The Manager and the Trust entered into an Administrative Services Agreement that obligates the Manager to provide or oversee administrative and management services to the Funds. As compensation for performing the duties required under the Administrative Services Agreement, the Manager receives an annualized fee of 0.10% of the average daily net assets of each of the Institutional, PlanAhead and Platinum Classes of the Funds. The Trust has adopted an Administrative Services Plan with respect to the Platinum Class of the Funds. As compensation for providing administrative services, the Manager receives an annualized fee of 0.55% of the average daily net assets of the Platinum Class of each Fund. A separate Administrative Services Plan has been adopted for the Cash Management Class of the Funds. As compensation for providing administrative services, the Manager receives an annualized fee of 0.07% of the average daily net assets of the Cash Management Class of each Fund. Distribution Plan The Trust, except for the Platinum Class of the Funds, has adopted a "defensive" Distribution Plan (the "Plan") in accordance with Rule 12b-1 under the Act, pursuant to which no fees may be charged to the Funds for distribution purposes. However, the Plan authorizes the fees received by the Manager to be used for distribution purposes. Under this plan, the Trust does not intend to compensate the Manager or any other party, either directly or indirectly, for the distribution of Trust shares. A separate Distribution Plan (the "Distribution Plan") has been adopted pursuant to Rule 12b-1 under the Act for the Platinum Class of the Funds. Under the Distribution Plan, as compensation for distribution assistance, the Manager receives an annualized fee of 0.25% of the average daily net assets of the Platinum class of each Fund. The fee will be payable without regard to whether the amount of the fee is more or less than the actual expenses incurred in a particular month by the Manager for distribution assistance. Service Agreement The Manager and the Trust entered into a Service Agreement which obligates the Manager to oversee additional shareholder servicing of the PlanAhead Class. As compensation for performing the duties required under the Service Agreement, the Manager receives 0.25% based on the daily net assets of the PlanAhead Class. Reimbursement and Waiver of Expenses The Manager contractually agreed to reimburse the Cash Management Class of each Fund for other expenses through February 28, 2006 to the extent that total annual fund operating expenses exceed 0.15% and 0.19% for the Money Market and U.S. Government Money Market Funds, respectively. - -------------------------------------------------------------------------------- 18 AMERICAN BEACON FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- The Manager contractually agreed to reimburse the PlanAhead Class of the Municipal Money Market Fund for other expenses through February 28, 2006 to the extent that total annual fund operating expenses exceed 0.99%.

The Manager contractually agreed to reimburse the Platinum Class of each Fund for distribution fees and other expenses through February 28, 2006 to the extent that total annual fund operating expenses exceed 0.99%.

However, recoupment will occur only if the Class' average net assets have grown or expenses have declined sufficiently to allow recoupment without causing its expense ratio to exceed the previously agreed upon contractual expense limit. The following waived fees or reimbursed expenses are subject to potential recovery expiring in: <Table> <Caption> U.S. GOVERNMENT MUNICIPAL YEAR MONEY MARKET MONEY MARKET MONEY MARKET - ---- ------------ --------------- ------------ 2006........................................................ $ 83,552 $77,375 $18,920 2007........................................................ 140,252 38,411 27,596 2008........................................................ 293,487 54,846 29,552 </Table> The Funds have not recorded a liability for this potential reimbursement due to the current assessment that a reimbursement is unlikely.

This Trustee receives an annual retainer of $40,000 plus $1,250 for each Board meeting attended. 3. FEDERAL INCOME AND EXCISE TAXES It is the policy of each of the Funds to comply with the requirements of Subchapter M of the Internal Revenue Code and to distribute substantially all net investment income as well as any net realized capital gains on the sale of investments. Therefore, no federal income tax provision is required. Net investment income and net realized gains (losses) may differ for financial statement and tax purposes because of temporary or permanent book-to-tax differences. To the extent these differences are permanent, reclassifications are made to the appropriate equity accounts in the period that the differences arise. Temporary differences are not reflected in the financial records. Dividends are determined in accordance with federal income tax regulations which may treat certain transactions differently than United States generally accepted accounting principles. Accordingly, the character of distributions and composition of net assets for tax purposes may differ from those reflected in the accompanying financial statements. The tax character of distributions during the years ended December 31, 2005 and December 31, 2004 were as follows (in thousands): <Table> <Caption> U.S. GOVERNMENT MUNICIPAL MONEY MARKET MONEY MARKET MONEY MARKET --------------------------- --------------------------- --------------------------- YEAR ENDED YEAR ENDED YEAR ENDED YEAR ENDED YEAR ENDED YEAR ENDED DECEMBER 31, DECEMBER 31, DECEMBER 31, DECEMBER 31, DECEMBER 31, DECEMBER 31, 2005 2004 2005 2004 2005 2004 ------------ ------------ ------------ ------------ ------------ ------------ Distributions paid from: Ordinary Income:* Cash Management Class....... $10,862 $1,712 $620 $299 $-- $-- Institutional Class......... 1,545 886 -- -- -- -- PlanAhead Class............. 7,159 1,558 108 94 -- -- Platinum Class.............. 1,013 211 123 28 -- -- Tax-Exempt Income:** Cash Management Class....... -- -- -- -- -- -- Institutional Class......... -- -- -- -- -- -- PlanAhead Class............. -- -- -- -- 30 7 Platinum Class.............. -- -- -- -- 67 12 ------- ------ ---- ---- --- --- TOTAL DISTRIBUTIONS PAID.................. $20,579 $4,367 $851 $421 $97 $19 ------- ------ ---- ---- --- --- </Table> - --------------- * For tax purposes short-term capital gains distributions are considered ordinary income distributions. ** Approximately 19% of interest earned was derived from investments in certain private activity bonds for purposes of the federal alternative minimum tax calculation.

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, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion.

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES American Beacon Master Trust (the "Trust"), formerly known as AMR Investment Services Trust, is registered under the Investment Company Act of 1940, as amended, as a no load, open-end management investment company that was organized as a trust under the laws of the Commonwealth of Massachusetts pursuant to a Declaration of Trust dated as of November 1, 2004. Prior to November 1, 2004, the Trust was organized as a trust under the laws of the State of New York. Beneficial interests in the Trust are divided into separate series, each having distinct investment objectives and policies. These financial statements relate to the American Beacon Master Money Market Portfolio, American Beacon Master U.S. Government Money Market Portfolio and American Beacon Master Municipal Money Market Portfolio (each a "Portfolio" and collectively the "Portfolios"). The objective of each Portfolio is current income, liquidity and the maintenance of a stable price of $1.00 per share. The assets of each Portfolio belong only to that Portfolio, and the liabilities of each Portfolio are borne solely by that Portfolio and no other. American Beacon Advisors, Inc. (the "Manager"), formerly known as AMR Investment Services, Inc., is a wholly-owned subsidiary of AMR Corporation, the parent company of American Airlines, Inc. ("American"), and was organized in 1986 to provide business management, advisory, administrative and asset management consulting services. The following is a summary of the significant accounting policies followed by the Portfolios. Security Valuation Securities of the Portfolios are valued at amortized cost, which approximates fair value. In the event that a deviation of 1/2 of 1% or more exists between the $1.00 per share price of the Portfolios, calculated at amortized cost, and the price per share calculated by reference to market quotations, or if there is any other deviation that the Trust's Board of Trustees (the "Board") believes would result in a material dilution to shareholders or purchasers, the Board will promptly consider the appropriate action that should be initiated. Security Transactions and Investment Income Security transactions are recorded on the trade date of the security purchase or sale. Interest income is earned from settlement date, recorded on the accrual basis, and adjusted, if necessary, for amortization of premiums or accretion of discounts on investment grade short-term securities and zero coupon instruments. For financial and tax reporting purposes, realized gains and losses are determined on the basis of specific lot identification. Federal Income and Excise Taxes The Portfolios will be treated as partnerships for federal income tax purposes. As such, each investor in a Portfolio will be taxed on its share of the Portfolio's ordinary income and capital gains. It is intended that each Portfolio's assets will be managed in such a way that an investor in the Portfolio will be able to satisfy the requirements of subchapter M of the Internal Revenue Code. Repurchase Agreements Under the terms of a repurchase agreement, securities are acquired by a Portfolio from a securities dealer or a bank that are subject to resale at a later date. Repurchase agreements are fully - -------------------------------------------------------------------------------- 42 AMERICAN BEACON MASTER TRUST NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- collateralized by U.S. Treasury or U.S. Government agency securities and are valued at cost, which approximates market value. All collateral is held at the Portfolio's custodian bank, State Street Bank and Trust Company, or at subcustodian banks. The collateral is monitored daily by the Manager so that the collateral's market value exceeds the carrying value of the repurchase agreement plus accrued interest. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated. Other Under the Trust's organizational documents, its officers and directors are indemnified against certain liability arising out of the performance of their duties to the Trust. In the normal course of business, the Trust enters into contracts that provide indemnification to the other party or parties against potential costs or liabilities. The Trust's maximum exposure under these arrangements is dependent on claims that may be made in the future and, therefore, cannot be estimated. The Trust has had no prior claims or losses pursuant to any such agreement. 2. TRANSACTIONS WITH AFFILIATES Management Agreement The Trust and the Manager are parties to a Management Agreement that obligates the Manager to provide or oversee the provision of all administrative, investment advisory and portfolio management services. The Manager serves as the sole investment advisor to each of the Portfolios. As compensation for performing the duties required under the Management Agreement, the Manager receives from the Portfolios 0.10% of the average daily net assets of each of the Portfolios. Interfund Lending Program Pursuant to an exemptive order by the Securities and Exchange Commission, the Portfolios, along with other registered investment companies having management contracts with the Manager, may participate in an interfund lending program. This program provides an alternative credit facility allowing the Money Market Portfolio to lend money to other participating series managed by the Manager. For the year ended December 31, 2005, the Money Market Portfolio earned $5,005 under the credit facility. This amount is included in interest income on the financial statements. Other Certain officers or Trustees of the Trust are also current or former officers or employees of the Manager or American. The Trust makes no direct payments to its officers. Mr. Feld and the non-interested Trustees (other than Mr. O'Sullivan) and their spouses are provided free unlimited air transportation on American. Retired Trustees and their spouses are provided free air transportation on American, up to a maximum annual value of $40,000. The Trust compensates each Trustee with payments in an amount equal to the Trustee's income tax on the value of this free airline travel. Mr. O'Sullivan as a retiree of American, already receives flight benefits. Mr. O'Sullivan receives an annual retainer of $40,000 plus $1,250 for each Board meeting attended. - -------------------------------------------------------------------------------- 43 AMERICAN BEACON FUNDS TAX INFORMATION FOR THE TAX YEAR ENDED DECEMBER 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- We are providing this information as required by the Internal Revenue Code.
