American Beacon Select Funds December 31, 2006 (AMERICAN BEACON ADVISORS) (PHOTO OF WILLIAM F. QUINN) FELLOW SHAREHOLDERS, Enclosed please find the Annual Report for the American Beacon Select Funds for the year ended December 31, 2006. During this time, the Select Funds outperformed their respective peer groups. After 17 consecutive 25-basis point (0.25%) rate hikes, the Federal Open Market Committee ("FOMC") held interest rates steady at 5.25% at their August 8th meeting. The Federal Reserve Board (the "Fed") will continue to weigh the risks of accelerating inflation and decelerating economic growth. At the final FOMC meeting in December 2006, the Fed acknowledged the cooling housing market, but remained primarily concerned about inflation. The FOMC should hold rates steady at least through the first half of 2007. The market is focused on slowing housing and auto data and pricing in an ease for the next move by the Fed (albeit in the late part of 2007). Fed officials continue to discuss that additional firming may be needed because inflation remains on the higher-end of their comfort range. Despite rising interest rates earlier in the year, the American Beacon Money Market Select Fund one-year return of 5.08% outperformed the Lipper Institutional Money Market Average return by 36 basis points (0.36%). The American Beacon U.S. Government Money Market Select Fund also outperformed the Lipper Institutional U.S. Government Money Market Average with a one-year return of 5.04% versus 4.69%. Please review the enclosed portfolio listings and detailed financial data. As always, we welcome the opportunity to serve your financial needs.

Thank you for your continued confidence in the American Beacon Select Funds. Sincerely, /s/ WILLIAM F. QUINN William F. Quinn President, American Beacon Select Funds 1 ECONOMIC OVERVIEW DECEMBER 31, 2006 (UNAUDITED) The initial estimate of the U.S. gross domestic product ("GDP") growth rate rose 3.5% in the fourth quarter, after rising a modest 2.0% in the third quarter of 2006. Consumer spending was the primary driver, up 4.4%. Consumers used credit cards to make up for diminished mortgage borrowing power. Business fixed investment fell 0.4%, the first decline since the first quarter of 2003. Inventories were up only $35.3 billion, trimming 0.7% from GDP growth. Growth rose solidly above the Fed's target after two quarters of coming in below, leaving room for debate on the implications of growth. In addition to the up tick in growth, the labor market remains healthy as payroll gains averaged 136,000 per month during the fourth quarter and the unemployment rate remained low at 4.5% in December. The Federal Open Market Committee ("FOMC") ended a streak of seventeen consecutive 25 basis point (0.25%) rate hikes at their August 8th meeting, leaving rates unchanged at 5.25% through the rest of 2006. Fed officials continue to weigh the risks of a slowing economy against the risks of higher inflation in determining the future direction of interest rates. At the December meeting, the Fed acknowledged the cooling housing market and its impact on economic growth, but inflation remained their chief concern. "...participants expressed concern that a failure of inflation to moderate as expected could entail significant costs if an upward drift in inflation expectations ensued," the minutes said. As a result, the Fed retained a tightening bias in its December statement maintaining the phrase that "the extent and timing of any additional firming that may be needed to address these risks will depend on the evolution of the outlook for both inflation and economic growth." The latest readings of consumer and producer prices indicate that the easing of inflationary pressures may be slow. The core consumer price index ("CPI") rose 0.2% in December after remaining flat in November, and the core producers price index ("PPI"), which also rose 0.2% during the month, came in above economists' expectations. In addition, despite a decline to an annual rate of 2.2% in November which was unchanged in December, the core personal consumption expenditures ("PCE") price index remains above the Fed's comfort range of 1-2%. U.S. Treasury yields rose during the fourth quarter as the likelihood of a Fed ease during the first quarter of 2007 began to dissipate. Though the yield curve remained inverted, Treasury yields reached five month highs in January 2007 on signals that the housing market is bottoming, inflation remains stubborn, and employment is strengthening. The FOMC should remain on hold at least through the first part of 2007 as Fed officials wait for signs that inflation is indeed moderating. If inflation remains above the Fed's comfort level for an extended period of time, an additional Fed tightening is possible. Despite the Fed's stated tightening bias, the market continues to expect an ease during the second half of 2007. 2 PERFORMANCE OVERVIEW AMERICAN BEACON SELECT FUNDS DECEMBER 31, 2006 (UNAUDITED) As the economy continued to show signs of strength during the year, the Fed continued tightening monetary policy through June 2006. Since then the Fed has been on hold with a tightening bias, resulting in a 5.25% fed funds target by year end. This was a move of 25 basis points (0.25%) for each of the first four FOMC meetings after starting the year at 4.25%. In response, the American Beacon Money Market Fund's weighted-average maturity ("WAM") was maintained below 45 days throughout the year. The primary strategy of the Fund was to buy variable rate securities, short-dated commercial paper and overnight investments. Due to maintaining a short WAM in a rising to stable interest rate environment, the Fund outperformed its Lipper peer group. This strategy will stay in place until economic data suggest the Fed is about to enter into an easing cycle. For the year ended December 31, 2006, the total return of the Money Market Select Fund was 5.08%. The Fund outperformed the Lipper Institutional Money Market Average return of 4.72% by 36 basis points (0.36%). Lipper Inc. ranked the Fund 6th among 357, 4th among 291, and 4th among 233 Institutional Money Market Funds for the one-year, three-year and five-year periods ended December 31, 2006, respectively. For the year ended December 31, 2006, the total return of the U.S. Government Money Market Select Fund was 5.04%. The Fund outperformed the Lipper Institutional U.S. Government Money Market Average return of 4.69% by 35 basis points (0.35%). Lipper Inc. ranked the Fund 3rd among 147, 2nd among 126 and 2nd among 106 Institutional U.S. Government Money Market Funds for the one-year, three-year and five-year periods ended December 31, 2006, respectively. 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 the 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 12/31/2006 --------------------------- 1 YEAR 5 YEARS 10 YEARS ------ ------- -------- Money Market (1, 2)....................................... 5.08% 2.51% 3.97% U.S. Government (1, 3).................................... 5.04% 2.46% 3.85% </Table> (1) Performance shown is historical and may not be indicative of future returns. Investment returns will vary, and share may be worth more or less at redemption than at original purchase. An investment in this Fund is neither insured nor guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of an investment at $1.00 per share it is possible to lose money by investing in the Fund. 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, 2006 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. A portion of the fees charged to the Money Market Fund was waived through 2001. Performance prior to waiving fees was lower than the actual returns for periods prior to 2001. (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 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 from that date through December 31, 2006 are for the Fund. Because the Companion Fund had moderately higher expenses, their performance was slightly worse than the Fund would have realized in the same period. A portion of the fees charged to the U.S. Government Fund has been waived. Performance prior to waiving fees was lower than the actual returns shown. 3 PERFORMANCE OVERVIEW AMERICAN BEACON SELECT FUNDS DECEMBER 31, 2006 (UNAUDITED) PORTFOLIO STATISTICS AS OF DECEMBER 31, 2006 <Table> <Caption> MONEY MARKET U.S. GOVERNMENT ------------ --------------- 7-day Current Yield* 5.28% 5.26% 7-day Effective Yield* 5.42% 5.39% 30-day Yield* 5.27% 5.23% Weighted Avg.

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, 2006 through December 31, 2006. ACTUAL EXPENSES The "Actual" line of the table provides 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 "Actual" 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 4 PERFORMANCE OVERVIEW AMERICAN BEACON SELECT FUNDS DECEMBER 31, 2006 (UNAUDITED) 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 "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 7/1/06- 7/1/06 12/31/06 12/31/06 --------- --------- -------------- MONEY MARKET Actual............................................ $1,000.00 $1,026.87 $0.61 Hypothetical (5% return before expenses).......... $1,000.00 $1,024.60 $0.61 U.S. GOVERNMENT MONEY MARKET Actual............................................ $1,000.00 $1,026.62 $0.61 Hypothetical (5% return before expenses).......... $1,000.00 $1,024.60 $0.61 </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 Select Fund and U.S. Government Money Market Select Fund 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, comprised of the American Beacon Money Market Select Fund and the American Beacon U.S. Government Money Market Select Fund (collectively, the "Funds") as of December 31, 2006, 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 five years in the period then ended. 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, 2006, 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 Dallas, TX February 27, 2007 6 AMERICAN BEACON SELECT FUNDS STATEMENT OF ASSETS AND LIABILITIES DECEMBER 31, 2006 (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) <Table> <Caption> U.S. GOVERNMENT MONEY MARKET MONEY MARKET -------------- ------------ ASSETS: Investment in Portfolio, at Value.................... $ 8,489,605 $ 536,661 Receivable from Manager for expense reimbursement (Note 2).......................................... -- 2 -------------- ------------ TOTAL ASSETS...................................... 8,489,605 536,663 -------------- ------------ LIABILITIES: Dividends payable.................................... 15,866 2,109 Other Liabilities.................................... 203 18 -------------- ------------ TOTAL LIABILITIES................................. $ 16,069 $ 2,127 -------------- ------------ NET ASSETS........................................... 8,473,536 534,536 ============== ============ ANALYSIS OF NET ASSETS: Paid-in-capital................................... 8,473,536 534,536 -------------- ------------ NET ASSETS............................................. $ 8,473,536 $ 534,536 ============== ============ Shares outstanding (no par value):..................... 8,473,536,032 534,536,362 Net asset value, offering and redemption price per share:............................................... 1.00 1.00 </Table> See accompanying notes See accompanying Financial Statements of the American Beacon Master Portfolios 7 AMERICAN BEACON SELECT FUNDS STATEMENT OF OPERATIONS YEAR ENDED DECEMBER 31, 2006 (IN THOUSANDS) <Table> <Caption> U.S. GOVERNMENT MONEY MARKET MONEY MARKET ------------ --------------- INVESTMENT INCOME ALLOCATED FROM PORTFOLIO: Interest Income...................................... $404,496 $16,108 Portfolio expenses...................................

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES American Beacon Select Funds (the "Trust") 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 ("U.S. Government 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 (66.70% and 95.25% at December 31, 2006, 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"), 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. 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. 10 AMERICAN BEACON SELECT FUNDS NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2006 Valuation of Shares The price per share is calculated on each day on which shares are offered for sale. 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 amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated. Recently Issued Accounting Pronouncements On July 13, 2006, the Financial Accounting Standards Board ("FASB") released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides guidance on how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing each Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. FIN 48 is effective for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, the Manager is evaluating the implications of FIN 48 and its potential impact on the financial statements. The Fund's net asset value per share will reflect FIN 48 adjustments no later than June 29, 2007, and any adjustments will be reflected in the Fund's Semi-Annual report to shareholders. In September 2006, the FASB issued Statement on Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of fair value measurements. FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The Manager is evaluating the impact of FAS 157; however, it is not expected to have a material impact on the Funds' net assets or results of operations. 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 the U.S. Government Fund for other expenses through February 28, 2007 to the extent that total annual Fund operating expenses exceed 0.12%. For the twelve months ended December 31, 2006, the Manager reimbursed expenses totaling $23,524 to the U.S. Government Fund. 11 AMERICAN BEACON SELECT FUNDS NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2006 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 for the U.S. Government Fund totaling $2,418, $25,649 and $23,524, will expire in 2007, 2008 and 2009 respectively. The U.S. Government Fund has not recorded a liability for this potential reimbursement due to the current assessment that a reimbursement is unlikely. Fees waived during 2003 totaling $11,073 expired in 2006 and will not be reimbursed to the Manager. During the twelve months ended December 31, 2006, due to asset growth and a reduction of expenses, the Manager recouped $49,000 from the Money Market Select Fund for expenses waived during 2003 and 2004 totaling $2,724 and $46,276, respectively. Fees waived during 2003 totaling $5,278 expired in 2006 and will not be reimbursed to the Manager. 3. FEDERAL INCOME 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.

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, 2006, 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, 2006, 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 Dallas, TX February 27, 2007 15 AMERICAN BEACON MASTER MONEY MARKET PORTFOLIO

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES American Beacon Master Trust (the "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. 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 the 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"), 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 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 custodian bank. 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. 25 AMERICAN BEACON MASTER TRUST NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2006 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. Recently Issued Accounting Pronouncements On July 13, 2006, the Financial Accounting Standards Board ("FASB") released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides guidance on how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing each Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. FIN 48 is effective for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, the Manager is evaluating the implications of FIN 48 and its potential impact on the financial statements. The Fund's net asset value per share will reflect FIN 48 adjustments no later than June 29, 2007, and any adjustments will be reflected in the Fund's Semi-Annual report to shareholders. In September 2006, the FASB issued Statement on Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of fair value measurements. FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The Manager is evaluating the impact of FAS 157; however, it is not expected to have a material impact on the Funds' net assets or results of operations. 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 twelve months ended 26 AMERICAN BEACON MASTER TRUST NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2006 December 31, 2006, the Money Market Portfolio earned $2,108 under the credit facility. This amount is included in interest income on the financial statements. 27 (UNAUDITED) AMERICAN BEACON SELECT FUNDS TAX INFORMATION FOR THE TAX YEAR ENDED DECEMBER 31, 2006 We are providing this information as required by the Internal Revenue Code.
