American Beacon Select Funds December 31, 2005 (BILL QUINN PICTURE) FELLOW SHAREHOLDERS: Enclosed please find the Annual Report for the American Beacon Select Funds for the year ended December 31, 2005. During this time, the Select Funds outperformed 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 American Beacon Select Funds produced strong relative returns for the period. The Money Market Select Fund returned 3.23% for the twelve months, outperforming the Lipper Institutional Money Market Average return of 2.84%. The U.S. Government Money Market Select Fund outpaced the Lipper Institutional U.S. Government Money Market Average with a return of 3.19% versus 2.85% for the Average. 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 William F. Quinn President, American Beacon Select 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 SELECT FUNDS 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 weighted-average maturity was maintained below 45 and 20 days for the Money Market and U.S. Government Money Market Select Funds, respectively, 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 American Beacon Money Market Select Fund was 3.23%. The Fund outperformed the Lipper Institutional Money Market Average return of 2.84% by 39 basis points. Lipper Inc. ranked the Fund 4th among 303, 3rd among 262 and 3rd among 211 Institutional Money Market Funds for the one-year, three-years and five-years ended December 31, 2005, respectively(1). For the twelve months ended December 31, 2005, the total return of the American Beacon U.S. Government Money Market Select Fund was 3.19%. The Fund outperformed the Lipper Institutional U.S. Government Money Market Average return of 2.85% by 34 basis points. Lipper Inc. ranked the Fund 3rd among 137 and 2nd among 120 Institutional U.S. Government Money Market Funds for the one-year and three-years ended December 31, 2005, respectively(1). The Lipper Institutional Money Market Average and the Lipper Institutional U.S. Government Money Market Average are calculated by taking an arithmetic average of the returns of the mutual funds in the Lipper Institutional Money Market Funds and Lipper Institutional U.S. Government Money Market Funds categories, respectively. Lipper is an independent mutual fund research and ranking service that ranks mutual funds in various categories by making comparative calculations using total returns. <Table> <Caption> ANNUALIZED TOTAL RETURNS --------------------------- AS OF 12/31/05 --------------------------- 1 YEAR 5 YEARS 10 YEARS ------ ------- -------- Money Market(1,2).................. 3.23% 2.35% 4.01% U.S. Government(1,3)............... 3.19% 2.28% 3.87% </Table> 1 Past performance is not indicative of future performance. An in- vestment in the American Beacon Select Funds is neither insured nor guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although each Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Funds. 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 The Fund's performance is derived from a combination of the Fund's performance and that of another fund (the "Companion Fund") not included in this report. The Companion Fund has been managed by American Beacon Advisors since its inception on September 1, 1987. Like the Fund, the Companion Fund invests all of its investable assets in a corresponding Portfolio of the American Beacon Master Trust. The performance results from inception through December 31, 1999 are those of the Companion Fund. The Fund began offering its shares on January 1, 2000. Thus, performance results shown from that date through December 31, 2005 are for the Fund. Because the Companion Fund had higher expenses, its performance was worse than the Fund would have realized in the same period. 3 The Fund's performance is derived from a combination of the Fund's performance and that of another fund (the "Companion Fund") not included in this report. The Companion Fund has been managed by American Beacon Advisors since its inception on March 2, 1992. Like the Fund, the Companion Fund invests all of its investable assets in a corresponding Portfolio of the American Beacon Master Trust. The performance results from inception through November 30, 2001 are those of the Companion Fund. The Fund began offering its shares on December 1, 2001. Thus, performance results shown from that date through December 31, 2005 are for the Fund. Because the Companion Fund had moderately higher expenses, its performance was slightly worse than the Fund would have realized in the same period. 3 PERFORMANCE OVERVIEW AMERICAN BEACON SELECT FUNDS -- CONTINUED December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- PORTFOLIO STATISTICS AS OF DECEMBER 31, 2005 <Table> <Caption> MONEY MARKET U.S. GOVERNMENT ------------ --------------- 7-day Current Yield* 4.23% 4.22% 7-day Effective Yield* 4.32% 4.31% 30-day Yield* 4.14% 4.12% Weighted Average Maturity 35 Days 9 Days Moody's Rating Aaa Aaa Standard & Poor's Rating AAAm AAAm </Table> * Annualized.

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 Fund 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. 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. 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 "Hypo- 4 PERFORMANCE OVERVIEW AMERICAN BEACON SELECT FUNDS -- CONTINUED December 31, 2005 (Unaudited) - -------------------------------------------------------------------------------- thetical" 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 --------- --------- --------------- MONEY MARKET Actual $1,000.00 $1,018.66 $0.59 Hypothetical (5% return before expenses) $1,000.00 $1,024.62 $0.59 U.S. GOVERNMENT Actual $1,000.00 $1,018.52 $0.63 Hypothetical (5% return before expenses) $1,000.00 $1,024.58 $0.63 </Table> * Expenses are equal to the Fund's annualized expense ratios for the six-month period of 0.12% and 0.12% for the Money Market and U.S. Government Money Market Select Funds, 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 AMERICAN BEACON SELECT FUNDS REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- The Board of Trustees and Shareholders of American Beacon Select Funds We have audited the accompanying statements of assets and liabilities of American Beacon Select Funds (formerly known as American AAdvantage Select Funds), comprised of the American Beacon Money Market Select Fund and the American Beacon U.S. Government Money Market Select Fund (collectively, the "Funds") (formerly known as the American AAdvantage Money Market Select Fund and the American AAdvantage U.S. Government Money Market Select Fund, respectively) as of December 31, 2005, and the related statements 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 periods indicated therein. 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 Select 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 - -------------------------------------------------------------------------------- 6 AMERICAN BEACON SELECT FUNDS STATEMENTS OF ASSETS AND LIABILITIES December 31, 2005 - -------------------------------------------------------------------------------- <Table> <Caption> U.S. GOVERNMENT MONEY MARKET MONEY MARKET -------------- --------------- (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) ASSETS: Investment in Portfolio, at value....................... $ 5,223,983 $ 197,267 Receivable from Manager for expense reimbursement (Note 2).................................................... -- 2 -------------- ------------ TOTAL ASSETS........................................ 5,223,983 197,269 -------------- ------------ LIABILITIES: Dividends payable....................................... 6,892 554 Other liabilities....................................... 164 19 -------------- ------------ TOTAL LIABILITIES................................... 7,056 573 -------------- ------------ NET ASSETS.................................................. $ 5,216,927 $ 196,696 ============== ============ ANALYSIS OF NET ASSETS: Paid-in-capital......................................... 5,216,927 196,696 -------------- ------------ NET ASSETS.................................................. $ 5,216,927 $ 196,696 ============== ============ Shares outstanding (no par value)....................... 5,216,926,513 196,695,519 ============== ============ Net asset value, offering and redemption price per share................................................. $ 1.00 $ 1.00 ============== ============ </Table> See accompanying notes - -------------------------------------------------------------------------------- 7 AMERICAN BEACON SELECT FUNDS STATEMENTS OF OPERATIONS Year Ended December 31, 2005 - -------------------------------------------------------------------------------- <Table> <Caption> U.S. GOVERNMENT MONEY MARKET MONEY MARKET ------------ --------------- (IN THOUSANDS) INVESTMENT INCOME ALLOCATED FROM PORTFOLIO: Interest income......................................... $ 167,726 $6,557 Portfolio expenses......................................

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES American Beacon Select Funds (the "Trust"), formerly known as the American AAdvantage Select 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 Select Fund and American Beacon U.S. Government Money Market Select Fund (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: the American Beacon Money Market Select Fund invests assets in the American Beacon Master Money Market Portfolio and the American Beacon U.S. Government Money Market Select Fund invests assets in the American Beacon Master U.S. Government Money Market Portfolio. Each Fund has the same investment objectives as its corresponding American Beacon Master Trust Portfolio. The value of such investments reflects each Fund's proportionate interest in the net assets of the corresponding portfolio (76.98% and 82.34% at December 31, 2005, of the American Beacon Master Money Market and U.S. Government 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. 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 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. Dividends The Funds generally declare dividends daily from net investment income and net short-term 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. - -------------------------------------------------------------------------------- 10 AMERICAN BEACON SELECT FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- Expenses Expenses directly attributable to a Fund are charged to that Fund's operations. Expenses incurred by the Trust with respect to both Funds are allocated in proportion to the net assets of each Fund, except where allocations of direct expenses to each Fund can otherwise be made fairly. Each share of each Fund bears equally those expenses that are allocated to the Fund as a whole. 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 the 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 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. FEES AND TRANSACTIONS WITH AFFILIATES Reimbursement of Expenses The Manager contractually agreed to reimburse each Fund for other expenses through February 28, 2006 to the extent that total annual Fund operating expenses exceed 0.12%. For the year ended December 31, 2005, the Manager reimbursed expenses totaling $25,649 to the U.S. Government Money Market Select Fund. Expense Reimbursement Plan The Funds have adopted an Expense Reimbursement Plan whereby the Manager may seek recoupment of expenses reimbursed for a period of up to three years. However, recoupment will occur only if a Fund's 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. Reimbursed expenses subject to potential recovery totaling $8,002 and $11,073 for the Money Market and U.S. Government Money Market Select Funds, respectively, will expire in 2006. Reimbursed expenses subject to potential recovery totaling $46,276 and $2,418 for the Money Market and U.S. Government Money Market Select Funds, respectively, will expire in 2007. - -------------------------------------------------------------------------------- 11 AMERICAN BEACON SELECT FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- Reimbursed expenses subject to potential recovery totaling $25,649 for the U.S. Government Money Market Select Fund will expire in 2008. The Funds have not recorded a liability for this potential reimbursement due to the current 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 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. 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.

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. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of American Beacon Master Trust 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 21, 2006 -

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 and American Beacon Master U.S. Government 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 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 - -------------------------------------------------------------------------------- 26 AMERICAN BEACON MASTER TRUST NOTES TO FINANCIAL STATEMENTS -- CONTINUED December 31, 2005 - -------------------------------------------------------------------------------- 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. - -------------------------------------------------------------------------------- 27 AMERICAN BEACON SELECT FUNDS TAX INFORMATION FOR THE TAX YEAR ENDED DECEMBER 31, 2005 (UNAUDITED) - -------------------------------------------------------------------------------- We are providing this information as required by the Internal Revenue Code.
