American Beacon Mileage Funds June 30, 2006 FELLOW SHAREHOLDERS, Enclosed please find the Semi-Annual Report for the American Beacon Mileage Funds for the six months ended June 30, 2006. During this time, the Mileage Funds outperformed their respective peer groups. The Federal Reserve (the "Fed") raised overnight rates four times during the period, resulting in a Fed Funds target rate of 5.25% as of June 30, 2006. In its June statement, the Fed acknowledged that economic growth is moderating but remained concerned that "the high levels of resource utilization and the prices of energy and other commodities have the potential to sustain inflation pressures." Despite rising interest rates, the American Beacon Money Market Mileage Funds produced strong relative returns for the period. The Money Market Mileage Fund-Mileage Class returned 2.08% for the six months, outperforming the Lipper Money Market Average return of 1.89%. The U.S. Government Money Market Mileage Fund-Mileage Class outpaced the Lipper U.S. Government Money Market Average with a return of 2.02% versus 1.93% for the Average. Additionally, the Municipal Money Market Mileage Fund-Mileage Class posted a gain of 1.29%, outperforming the Lipper Tax-Exempt Money Market Average return of 1.27%.

Quinn President, American Beacon Mileage Funds (BILL QUINN PICTURE) 1 ECONOMIC OVERVIEW JUNE 30, 2006 (UNAUDITED) - -------------------------------------------------------------------------------- TThe U.S. economy expanded at an annual rate of 5.6% in the first quarter of 2006 thanks to strong consumer spending and business investment. However, soaring gasoline prices and a slowdown in the housing market caused the second quarter gross domestic product ("GDP") growth to slow to an estimated 2.5%. It also appeared that the labor market was cooling as payroll gains came in below consensus, rising 325,000 during the second quarter versus a revised 629,000 in the first quarter of 2006. Despite the slowdown in payroll growth, the unemployment rate continued to decline during the second quarter, coming in at a low 4.6% for the month of June. In addition, June average hourly earnings climbed 3.9% from the prior year, fueling concerns that the low unemployment rate was putting upward pressure on inflation. The Federal Reserve Board raised overnight rates by 25 percentage points at each of the first four meetings in 2006, resulting in a Fed Funds target rate of 5.25% as of June 30, 2006. In its June statement, the Fed acknowledged that economic growth was moderating but remained concerned that "the high levels of resource utilization and the prices of energy and other commodities have the potential to sustain inflation pressures." They did remove the phrase "some further policy firming may yet be needed" and stated that the extent and timing of any additional firming "will depend on the evolution of the outlook for both inflation and economic growth." The Fed remains data dependent, leaving the door open for either a pause or another rate hike at their next several meetings. As expected, we began to see higher energy and commodity prices being passed on to the consumer in the form of higher goods prices during the period. The core Consumer Price Index ("CPI") rose more than forecast in June, up 0.3% for the month and 2.6% year over year. This was the fourth consecutive month of core inflation rising 0.3%, which according to Bloomberg, is the longest such stretch since January to April 1995. Bernanke called the recent increases in core prices "unwelcome developments" and said central bankers "will be vigilant" to ensure inflation doesn't become entrenched. As a result, if core inflation numbers continue to rise in the coming months, the Fed may prolong its tightening cycle. At the end of the second quarter, the Fed Funds future market was indicating a chance of another 0.25% rate increase by the end of the third quarter. The yield curve shifted up as the Fed Funds rate rose during the second quarter 2006. However, the curve continued to invert as yields on the 6-month Treasury bill ended the quarter at 5.23% versus 5.15% for the 2-year note and 5.14% for the 10-year note. 2 PERFORMANCE OVERVIEW AMERICAN BEACON MONEY MARKET MILEAGE FUND(SM) JUNE 30, 2006 (UNAUDITED) - -------------------------------------------------------------------------------- The Money Market Mileage Fund maintained the strategy of purchasing 3-month variable rate securities based on the London Interbank Offered Rate (LIBOR) in addition to short-dated commercial paper during the period in response to the rising interest rate environment. With the Fed Funds futures market indicating a chance of another 25 percentage point rate increase by the end of the third quarter, the Money Market Mileage Fund continued to keep its weighted-average maturity relatively short. However, we will continue to monitor economic trends and adjust our weighted- average maturity. In addition, we remain conservative on credit risk given the tight credit spread environment. For the six months ended June 30, 2006, the total return of the American Beacon Money Market Mileage Fund -- Mileage Class was 2.08%. The Fund outperformed the Lipper Money Market Average return of 1.89% by 19 percentage points. The Lipper Money Market Average is calculated by taking an arithmetic average of the returns of the mutual funds in the Lipper 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. <Table> <Caption> MILEAGE CLASS TOTAL RETURNS ------------------------------------- AS OF JUNE 30, 2006 ------------------------------------- 1 YEAR 3 YEARS* 5 YEARS* 10 YEARS* ------ -------- -------- --------- American Beacon Money Market Mileage Fund 3.74% 2.02% 1.82% 3.51% Lipper Money Market Average 3.35% 1.68% 1.52% 3.26% </Table> * Annualized <Table> <Caption> ANNUALIZED TOTAL RETURNS --------------------------- AS OF 6/30/2006 --------------------------- 1 YEAR 5 YEARS 10 YEARS ------ ------- -------- Mileage Class(1).............. 3.74% 1.82% 3.51% Platinum Class(1)............. 3.12% 1.26% 2.99% </Table> 1 Performance shown is historical and may not be indicative of future returns.

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 January 1, 2006 through June 30, 2006. 3 PERFORMANCE OVERVIEW AMERICAN BEACON MONEY MARKET MILEAGE FUND(SM) -- CONTINUED JUNE 30, 2006 (UNAUDITED) - -------------------------------------------------------------------------------- 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 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 1/1/06- 1/1/06 6/30/06 6/30/06 --------- --------- -------------- MILEAGE CLASS Actual $1,000.00 $1,020.82 $3.08 Hypothetical (5% return before expenses) $1,000.00 $1,021.74 $3.09 PLATINUM CLASS Actual $1,000.00 $1,017.75 $6.12 Hypothetical (5% return before expenses) $1,000.00 $1,018.72 $6.13 </Table> * Expenses are equal to the Fund's annualized expense ratio for the six- month period of 0.62% and 1.22% for the Mileage 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 (181) by days in the year (365) to reflect the half-year period. 4 PERFORMANCE OVERVIEW AMERICAN BEACON U.S. GOVERNMENT MONEY MARKET MILEAGE FUND(SM) JUNE 30, 2006 (UNAUDITED) - -------------------------------------------------------------------------------- The U.S. Government Money Market Mileage Fund maintained the strategy of purchasing 3-month variable rate securities based on the London Interbank Offered Rate (LIBOR) in addition to short-dated commercial paper during the period in response to the rising interest rate environment.

The variable rate demand note (VRDN) market provided the most attractive investment option throughout the period. Rates on these securities remained appealing, as short-term interest rates were increased at seventeen consecutive Fed meetings since June 2004. We will continue to focus purchases on attractively priced VRDNs backed by letters of credit or bond insurance and may buy selective fixed rate instruments when evidence emerges that the Fed has completed its current tightening cycle. For the six months ended June 30, 2006, the total return of the American Beacon Municipal Money Market Mileage Fund -- Mileage Class was 1.29%. The Fund outperformed the Lipper Tax-Exempt Money Market Average return of 1.27% by 2 percentage points. 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.

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES American Beacon Mileage Funds (the "Trust"), formerly known as the American AAdvantage Mileage Funds, is organized as a Massachusetts business trust under a Declaration of Trust dated February 14, 1995 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 Mileage Fund, American Beacon U.S. Government Money Market Mileage Fund and American Beacon Municipal Money Market Mileage 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: <Table> <Caption> AMERICAN BEACON: AMERICAN BEACON MASTER TRUST: - ---------------- INVESTS ASSETS IN ----------------------------- Money Market Mileage Fund Money Market Portfolio U.S. Government Money Market Mileage Fund U.S. Government Money Market Portfolio Municipal Money Market Mileage 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 (4.43%, 5.70% and 75.41% at June 30, 2006 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: CLASS OFFERED TO: SERVICE AND DISTRIBUTION FEES: - ----- ----------- ------------------------------ MILEAGE CLASS Individuals and certain grantor trusts Distribution Fee -- 0.25% PLATINUM CLASS Investors investing through selected financial Administrative Service Fee -- 0.65% institutions (such as banks and broker-dealers) Distribution Fee -- 0.25% 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. 12 AMERICAN BEACON MILEAGE FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED JUNE 30, 2006 (UNAUDITED) - -------------------------------------------------------------------------------- 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. 2. TRANSACTIONS WITH AFFILIATES Management Agreement The Manager and the Trust entered into a Management Agreement that obligates the Manager to provide or oversee administrative and management services to the Funds. As compensation for performing administrative duties required under the Management Agreement, the Manager receives an annualized fee of 0.10% of the average daily net assets of each of the Funds. Administrative Services Plan 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 0.65% of the average daily net assets of the Platinum Class of each Fund. Distribution Plan The Trust has adopted a Distribution Plan (the "Plan") pursuant to Rule 12b-1 under the Act. A separate plan has been adopted by the Mileage Class and Platinum Class of the Funds. Under each Plan, as compensation for distribution assistance, the Manager receives an annualized fee of 0.25% of the average daily net assets of each Class. 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. In adopting the Plan, the 13 AMERICAN BEACON MILEAGE FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED JUNE 30, 2006 (UNAUDITED) - -------------------------------------------------------------------------------- Trustees determined that there was a reasonable likelihood that the Plan would benefit the Funds and the shareholders of the respective Classes. Reimbursement and Waiver of Expenses The Manager contractually agreed to reimburse the Platinum Class of the Municipal Money Market and U.S. Government Money Market Mileage Funds for distribution fees and other expenses through February 28, 2007 to the extent that total annual fund operating expenses exceed 1.20%. During the six months ended June 30, 2006, the Manager waived or reimbursed expenses as follows: <Table> <Caption> FUND AMOUNT - ---- ------ U.S. Government Money Market Mileage Fund Platinum Class..................... $9,470 Municipal Money Market Mileage Fund Platinum Class........................... $4,079 </Table> The Manager voluntarily waived distribution fees totaling $17,390 for the Platinum Class of the Money Market Mileage Fund so that distribution fees received from the Fund were equal to the cost incurred by the Manager during the six months ended June 30, 2006. During the six months ended June 30, 2006, the Manager voluntarily waived or reimbursed expenses for the Mileage Class of the U.S. Government Money Market Mileage Fund to the extent that total annual fund operating expenses exceed 0.70%. The Manager waived or reimbursed distribution fees totaling $11,562 during the period. Expense Reimbursement Plan The Funds have 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 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................................................. $200,654 $ 7,709 $ 9,134 2007................................................. 239,870 11,563 11,600 2008................................................. 25,380 21,889 5,739 2009................................................. 17,390 21,032 4,079 </Table> 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 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 plus a fee for each Board meeting attended. 14 AMERICAN BEACON MILEAGE FUNDS NOTES TO FINANCIAL STATEMENTS -- CONTINUED JUNE 30, 2006 (UNAUDITED) - -------------------------------------------------------------------------------- 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 six months ended June 30, 2006 and the year ended December 30, 2005 were as follows (in thousands): <Table> <Caption> MUNICIPAL MONEY MONEY MARKET U.S. GOVERNMENT MONEY MARKET MARKET -------------------------------- -------------------------------- ---------------- SIX MONTHS ENDED YEAR ENDED SIX MONTHS ENDED YEAR ENDED SIX MONTHS ENDED JUNE 30, DECEMBER 31, JUNE 30, DECEMBER 31, JUNE 30, 2006 2005 2006 2005 2006 ---------------- ------------ ---------------- ------------ ---------------- (UNAUDITED) (UNAUDITED) (UNAUDITED) DISTRIBUTIONS PAID FROM: ORDINARY INCOME:* Mileage Class......... 1,007 1,317 208 241 -- Platinum Class........ 6,083 7,885 91 96 -- TAX-EXEMPT INCOME: Mileage Class......... -- -- -- -- 291 Platinum Class........ -- -- -- -- 42 ----- ----- --- --- --- TOTAL DISTRIBUTIONS.. 7,090 9,202 299 337 333 ===== ===== === === === <Caption> MUNICIPAL MONEY MARKET ------------ YEAR ENDED DECEMBER 31, 2005 ------------ DISTRIBUTIONS PAID FROM: ORDINARY INCOME:* Mileage Class......... -- Platinum Class........ -- TAX-EXEMPT INCOME: Mileage Class......... 437 Platinum Class........ 57 --- TOTAL DISTRIBUTIONS.. 494 === </Table> - -------- * For tax purposes short-term capital gains distributions are considered ordinary income distributions.

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 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. 31 AMERICAN BEACON MASTER TRUST NOTES TO FINANCIAL STATEMENTS -- CONTINUED JUNE 30, 2006 (UNAUDITED) - -------------------------------------------------------------------------------- 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 six months ended June 30, 2006, the Money Market Portfolio earned $79 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 plus a fee for each Board meeting attended. 32 DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT AGREEMENTS OF THE FUNDS AND THE PORTFOLIOS (UNAUDITED) - -------------------------------------------------------------------------------- At its February 17, 2006 meeting, the Board of Trustees (the "Board") considered the renewal of the existing Management Agreements (the "Agreements") between the Manager and the American Beacon Mileage Funds, on behalf of the American Beacon Money Market Mileage Fund, American Beacon Municipal Money Market Mileage Fund, and the American Beacon U.S. Government Money Market Mileage Fund (collectively, the "Funds"), and between the Manager and the American Beacon Master Trust, on behalf of the American Beacon Master Money Market Portfolio, American Beacon Master Municipal Money Market Portfolio, and the American Beacon Master U.S. Government Money Market Portfolio (collectively, the "Portfolios"). The term "Funds" is used throughout this section to refer to both the Funds and the Portfolios. In preparation for the Board's consideration to renew the Agreements, the Board and its Investment Committee undertook steps to gather and consider information furnished by the Manager and Lipper, Inc. ("Lipper"). The Board, with the assistance of independent legal counsel, requested and received certain relevant information from the Manager. In addition, the Board's Investment Committee worked with Lipper to obtain relevant comparative information regarding the performance, fees and expenses of the Funds. The Investment Committee held separate meetings on December 8, 2005, February 8, 2006 and February 17, 2006 to consider the information provided by Lipper. Further, the Board took into consideration information furnished for the Board's review and consideration throughout the year at regular Board and Investment Committee meetings, as well as information specifically prepared in connection with the renewal process. The Board considered, among other materials, responses by the Manager to inquiries requesting: - a description of any significant changes (actual or anticipated) to principal activities, personnel, services provided to the Funds, or any other area, including how these changes might affect the Funds; - a copy of the Manager's most recent audited or unaudited financial statements as well as Parts I and II of its Form ADV; - a summary of any material past, pending or anticipated litigation or regulatory proceedings involving the Manager or its personnel, including the results of any recent regulatory examination or independent audit; - a cost/profitability analysis of the Manager and any actual or anticipated economies of scale in relation to the services it provides to the Funds, if available; - an analysis of compensation, including a comparison with fees charged to other clients for which similar services are provided, any proposed changes to the fee schedule and the effect of any fee waivers; - an evaluation of any other benefits to the Manager or Funds as a result of their relationship, if any; - confirmation that the Manager's financial condition does not raise concerns that it would be unable to continue providing the same scope and quality of services to the Funds; - a description of the scope of portfolio management services provided to the Funds, including whether such services differ from the services provided to other clients, including other registered investment companies; - a description of the personnel who are assigned primary responsibility for managing the Funds, including any changes during the past year; - a description of the basis upon which portfolio managers are compensated, including any "incentive" arrangements; - a discussion regarding the Manager's participation in "soft dollar" arrangements, if any; - a description of any actual or potential conflicts of interest anticipated in managing Fund assets; - a description of trade allocation procedures among accounts managed by the firm; - a summary of any material changes to the Manager's compliance program with regard to federal, state, corporate and Fund requirements; 33 DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT AGREEMENTS OF THE FUNDS AND THE PORTFOLIOS -- CONTINUED (UNAUDITED) - -------------------------------------------------------------------------------- - a discussion of any material compliance problems and remedial actions; - information regarding the Manager's code of ethics, insider trading policy and disaster recovery plan, including a description of any material changes thereto; - a description of the Manager's affiliation with any broker-dealer; - a discussion of any anticipated change in the Manager's controlling persons; - verification of the Manager's insurance coverage with regards to the services provided to the Funds; - a comparison of the performance of each Fund to appropriate indices, including comments on the relative performance of each Fund versus comparable indices; - a discussion, if applicable, of any underperformance by a Fund relative to its peer group; - an analysis of any material complaints received from Fund shareholders; - a description of the Manager's securities lending practices and the fees received from such practices; - a description of the portfolio turnover rate and average execution costs for each Fund; - a discussion of whether the Manager receives, with respect to trade execution for the Funds, other special compensation, including any payment for order flow; and - a description of how expenses that are not readily identifiable to a particular Fund are allocated. The Board also obtained an analysis provided by Lipper that compared: (i) investment performance of each Fund versus comparable investment companies and appropriate indices; (ii) total Fund expenses of each Fund versus comparable mutual funds, and (iii) each Fund's investment advisory fees versus comparable mutual funds. For each Fund, the class used for comparative purposes was the class with the longest performance history, which in most cases is the Institutional Class. References below to each Fund's Lipper peer group are to the group of comparable mutual funds included in the analysis provided by Lipper. The Trustees also received a memorandum from their legal counsel detailing the Board's responsibilities pertaining to the renewal of the Agreements. This memorandum explained the regulatory requirements surrounding the Board's process for evaluating investment advisors and the terms of the contracts. Provided below is an overview of the primary factors the Board considered at its February 2006 meeting. The Board did not identify any particular information that was most relevant to its consideration to renew the Agreements, and each Trustee may have afforded different weight to the various factors. CONSIDERATIONS WITH RESPECT TO ALL FUNDS In determining whether to approve the continuance of the Agreements, the Board considered the best interests of each Fund separately. In addition, while the Agreements for all of the Funds were considered at the same Board meeting, the Board considered each Fund's investment management relationship separately. In each instance, the Board considered, among other things, the following factors: (1) the nature and quality of the services provided; (2) the investment performance of the Fund; (3) the Manager's cost for providing the services and the profitability of the advisory business to the Manager; (4) the extent to which economies of scale have been taken into account in setting the fee schedule; and (5) whether fee levels reflect these economies of scale for the benefit of Fund investors. The Trustees posed questions to various management personnel of the Manager regarding certain key aspects of the material submitted in support of the renewal. 34 DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT AGREEMENTS OF THE FUNDS AND THE PORTFOLIOS -- CONTINUED (UNAUDITED) - -------------------------------------------------------------------------------- Nature, Extent and Quality of Services With respect to the renewal of the Agreements, the Board considered: the Manager's ability to retain key investment personnel and to provide consistent performance and an active client service program; the Manager's goal to provide consistent above average long-term performance at low cost; the continuing efforts by the Manager to add new Funds so as to enhance the Trusts' product line; the Manager's record in building improved compliance, control and credit functions that reduce risks to the Funds; and the addition of personnel to manage the Funds, promote sales and improve services. Based on this information, the Board concluded that the nature, extent and quality of the management services provided by the Manager were appropriate for each Fund and, thus, supported a decision to renew the Agreements. Investment Performance The Board evaluated the comparative information provided by Lipper and the Manager regarding each Fund's investment performance relative to its benchmark index(es) and peer group. The Board also considered the performance reports and discussions with management at Board and Committee meetings throughout the year. Discussions regarding the Board's considerations with respect to each Fund's performance are below under "Additional Considerations and Conclusions with Respect to each Fund." Cost of Services and Profits Realized In analyzing the cost of services and profitability of the Manager in connection with its investment advisory services to a Fund, the Board considered the Manager's operations and low cost structure. The Board considered that the Manager receives service and administrative fees to compensate the Manager for providing administrative services to the Funds and to compensate third-party administrators and broker-dealers for services to Fund shareholders. Discussions regarding the Board's considerations with respect to each Fund's fee rates are set forth below under "Additional Considerations and Conclusions with Respect to each Fund." Economies of Scale In considering the reasonableness of the management fees, the Board considered whether economies of scale will be realized as the Funds grow and whether fee levels reflect these economies of scale for the benefit of Fund shareholders. With respect to the management fee, the Board acknowledged the Manager's low cost structure and the increasing costs of personnel, technology and operations. Based on these considerations, the Board concluded that the Funds' fee structures are reasonably designed to pass on economies of scale to Fund shareholders. Benefits to be Derived from the Relationship with the Funds The Board considered the "fall-out" or ancillary benefits that accrue to the Manager as a result of the advisory relationships with the Funds, including greater exposure in the marketplace with respect to the Manager's investment process and expanding the level of assets under management by the Manager. After consideration of this information, the Board concluded that the potential benefits accruing to the Manager by virtue of its relationships with the Funds appear to be fair and reasonable. ADDITIONAL CONSIDERATIONS AND CONCLUSIONS WITH RESPECT TO EACH FUND The Board considered the relative performance of each Fund versus the respective Lipper Average, which includes all comparable funds in the Lipper category, and the Lipper Index, which includes up to the 30 largest funds in the respective Lipper category where the Fund is classified by Lipper. 35 DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT AGREEMENTS OF THE FUNDS AND THE PORTFOLIOS -- CONTINUED (UNAUDITED) - -------------------------------------------------------------------------------- Additional Considerations and Conclusions with Respect to the Money Market Mileage Fund In considering the renewal of the Agreements with the Fund, the Board considered performance data for various periods ended December 31, 2005. In this regard, they considered that: (1) the Mileage Class total return performance was in the 1st quintile for all relevant periods except the ten-year period where its performance was in the 2nd quintile compared to the returns of a peer group of mutual funds identified by Lipper as having an investment objective similar to the Fund ("Lipper Universe"), and (2) the Mileage Class outperformed the Lipper Money Market Average and the Lipper Money Market Index for all relevant periods. In addition, the Board considered the fees payable under the Agreements. In this regard, they considered that: (1) the Mileage Class total expenses were in the 2nd quintile and actual management fees (including administrative fees) were in the 1st quintile compared to the expenses and fees of a peer group of similar funds classified by Lipper ("Fee Universe") where the 1st quintile represents the lowest fees or expenses among the group, and (2) the Manager's explanation that fee schedule "breakpoints" were not warranted due to, among other factors, the low, base management fee charged to the Fund. Based on these considerations and those noted above with respect to all Funds, the Board: (1) concluded that the fees paid to the Manager under the Agreements are fair and reasonable; (2) concluded that the profits to the Manager are reasonable in light of the quality of services provided to the Fund, including direct management of the Fund's assets; (3) determined that the Fund and its shareholders would benefit from the Manager's continued management of the Fund; and (4) approved the renewal of the Agreements with respect to the Fund. Additional Considerations and Conclusions with Respect to the Municipal Money Market Mileage Fund In considering the renewal of the Agreements with the Fund, the Board considered performance data for various periods ended December 31, 2005. In this regard, they considered that: (1) the Mileage Class total return performance was in the 2nd quintile for the two-, three- and ten-year periods and 3rd quintile for the one-, four- and five-year periods compared to the Lipper Universe, and (2) the Mileage Class outperformed the Lipper Tax Exempt Money Market Average and underperformed the Lipper Tax Exempt Money Market Index for all relevant periods. In addition, the Board considered the fees payable under the Agreements. In this regard, they considered that: (1) the Mileage Class actual management fees (including administrative fees) were in the 1st quintile and total expenses were in the 4th quintile compared to the Fee Universe where the 1st quintile represents the lowest fees or expenses among the group; (2) the Manager's explanation that fee schedule "breakpoints" were not warranted due to, among other factors, the low, base management fee charged to the Fund; (3) the Manager has contractually agreed to waive fees and/or reimburse expenses to the extent necessary to maintain a competitive total expense ratio for the Platinum Class of the Fund; and (4) the Manager's profitability analysis indicated that it incurred a loss on the services it provided to the Fund. Based on these considerations and those noted above with respect to all Funds, the Board: (1) concluded that the fees paid to the Manager under the Agreements are fair and reasonable; (2) concluded that the profits to the Manager are reasonable in light of the quality of services provided to the Fund, including direct management of the Fund's assets; (3) determined that the Fund and its shareholders would benefit from the Manager's continued management of the Fund; and (4) approved the renewal of the Agreements with respect to the Fund. Additional Considerations and Conclusions with Respect to the U.S. Government Money Market Mileage Fund In considering the renewal of the Agreements with the Fund, the Board considered performance data for various periods ended December 31, 2005.
