During this time, the American Beacon Mileage Funds outpaced 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 four times with increases of 25 basis points each time to end the six-month period at 3.25%. These widely expected moves were a continuation of the Fed's stated process of removing monetary policy accommodation at a "measured" pace. The Federal Open Market Committee ("FOMC") has now boosted the target rate a quarter percentage point at each of their last nine meetings. The FOMC stated that, even after these actions, "the stance of monetary policy remains accommodative and, coupled with robust underlying growth in productivity, is providing ongoing support to economic activity. Although energy prices have risen further, the expansion remains firm and labor market conditions continue to improve gradually. Pressures on inflation have stayed elevated, but longer-term inflation expectations remain well contained." The American Beacon Mileage Funds produced strong returns for the period. The Money Market Mileage Fund-Mileage Class returned 1.11% for the six months, outperforming the Lipper Money Market Average return of 0.92%. The U.S. Government Money Market Mileage Fund-Mileage Class outpaced the Lipper U.S. Government Money Market Average with a return of 0.99% versus 0.94% for the Average. Additionally, the Municipal Money Market Mileage Fund-Mileage Class posted a gain of 0.81%, outperforming the Lipper Tax-Exempt Money Market Average return of 0.73%. Looking forward, expectations are that the FOMC will vote to hike the overnight federal funds rate another 25 basis points at their upcoming meetings in August and September. During this rising rate environment, we will monitor the duration and quality of the money market portfolios as we evaluate economic growth, inflation, and the direction of interest rates. Please review the enclosed portfolio listings and detailed financial data. As always, we welcome the opportunity to serve your financial needs.

Quinn President, American Beacon Mileage Funds 1 ECONOMIC OVERVIEW (Unaudited) ================================================================================ Much like 2004, the financial markets have been keenly focused on the "Non-Farm Payroll" numbers in 2005. With employment demonstrating solid growth and concerns about inflation building, the Federal Reserve has raised overnight borrowing rates at nine consecutive Federal Open Market Committee (FOMC) meetings since June 2004. Over the past six months, the economy has shown significant growth across all sectors, particularly in housing, given single- family housing starts averaged more than 1.65 million units annually. With the economy expanding at a moderate pace, housing activity at high levels and business investment and manufacturing stronger, the Federal Reserve is predicted to continue raising the Fed Funds rate to at least 4.00% (according to economists' forecasts and the Fed Funds futures contracts) by December 2005. The yield curve flattened throughout the first six months of 2005, which led Federal Reserve Chairman Greenspan to label the flattening and potential inversion a "conundrum." Credit spreads remained at or near historically tight levels with little evidence of widening. Steady growth in the labor market and significant price increases in oil have changed the focus of the FOMC toward inflation. Higher employment typically puts pressure on labor costs that lead to higher prices for consumers. Core prices rose rapidly in the first half of the year, elevated by the indirect effects of higher energy prices on business costs and increases in non-oil import prices that reflect past dollar depreciation and the surge in global prices for primary commodities. The FOMC has consistently reiterated its stance that the tightening cycle would occur at a "measured" pace, and policymakers signaled that they will respond to changes in economic conditions in order to maintain their goal of price stability. 2 PERFORMANCE OVERVIEW AMERICAN BEACON MONEY MARKET MILEAGE FUND(SM) (Unaudited) ================================================================================ The U.S. economy continued to grow at a solid pace as Gross Domestic Product (GDP) for the first quarter of 2005 was revised upward to 3.8%. Although nonfarm payroll growth came in below consensus expectations, the unemployment rate dropped to 5.0% in June, its lowest point since September 2001. Crude oil prices remained elevated, approaching $60 per barrel, leading to concerns of reduced consumer spending and lower corporate profit margins. Still, GDP growth remains steady as estimates for the full year 2005 are in the 3.5-4% range. The American Beacon Money Market Mileage Fund continued to maintain the strategy of purchasing 3-month LIBOR-based variable rate securities in addition to short-dated commercial paper in this rising interest rate environment. The FOMC raised overnight rates by 25 basis points at both the May and June meetings, resulting in a Fed Funds target rate of 3.25%. The FOMC maintained its "measured" policy adjustment posture at the June meeting, ending speculation that they were done raising rates. "Although energy prices have risen further, the expansion remains firm and labor market conditions continue to improve gradually," the FOMC said in its statement accompanying the decision. Although the Fed characterized inflation pressures as "elevated," the headline Personal Consumption Expenditure deflator was a benign 2.2% at its May reading and the Consumer Price Index (CPI) was unchanged in June. Currently, with the Eurodollar futures market pricing in a Fed Funds rate of 4.00% by the end of the year, the Money Market Mileage Fund will maintain its weighted-average maturity relatively short. However, the Fund's investment advisor will continue to monitor economic trends and adjust the Fund's duration posture accordingly. For the six months ended June 30, 2005, the total return of the American Beacon Money Market Mileage Fund - Mileage Class was 1.11%. The Fund outperformed the Lipper Money Market Average return of 0.92% by 19 basis 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.

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 this 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 October 31, 1995 are those of the Companion Fund's Mileage Class of shares. The Fund began offering its shares on November 1, 1995. Thus, performance results shown from that date through June 30, 2005 are for the Fund. Because the Companion Fund had lower expenses, its performance was better 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.

FUND EXPENSE EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1)transaction costs and (2)ongoing costs, including management fees, administrative service fees, and other Fund expenses. The examples below are intended to help you understand the ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period in each Class and held for the entire period from January 1, 2005 through June 30, 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 4 PERFORMANCE OVERVIEW AMERICAN BEACON MONEY MARKET MILEAGE FUND(SM) - CONTINUED (Unaudited) ================================================================================ 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.

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 nine consecutive FOMC meetings since June 2004. In the current interest rate environment, the Fund will continue to focus on attractively priced VRDNs backed by letters of credit or bond insurance in anticipation of further "measured" rate hikes by the Federal Reserve. For the six months ended June 30, 2005, the total return of the American Beacon Municipal Money Market Mileage Fund - Mileage Class was 0.81%. The Fund outperformed the Lipper Tax-Exempt Money Market Average return of 0.73% by 8 basis 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.

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. 9 PERFORMANCE OVERVIEW AMERICAN BEACON MUNICIPAL MONEY MARKET MILEAGE FUND(SM) - CONTINUED (Unaudited) ================================================================================ BEGINNING ENDING ACCOUNT ACCOUNT EXPENSES PAID VALUE VALUE DURING PERIOD* 1/1/05 6/30/05 1/1/05-6/30/05 --------- ------- -------------- MILEAGE CLASS Actual $1,000.00 $1,008.14 $3.18 Hypothetical (5% return before expenses) $1,000.00 $1,021.63 $3.20 PLATINUM CLASS Actual $1,000.00 $1,005.34 $5.97 Hypothetical (5% return before expenses) $1,000.00 $1,018.84 $6.01 *Expenses are equal to the Fund's annualized expense ratios for the six-month period of 0.64% and 1.20% 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. 10 AMERICAN BEACON MILEAGE FUNDS STATEMENTS OF ASSETS AND LIABILITIES June 30, 2005 (Unaudited) ================================================================================ U.S. GOVERNMENT MUNICIPAL MONEY MARKET MONEY MARKET MONEY MARKET ============ =============== ============ (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) ASSETS: Investment in Portfolio, at value $ 413,371 $ 15,061 $ 26,728 Receivable for fund shares sold .............. 25 - - Receivable from Manager for expense reimbursement (Note 2) ............ 1 1 - Prepaid expenses ............................. 52 19 17 ------------ ---------- ----------- TOTAL ASSETS .............................. 413,449 15,081 26,745 ------------ ---------- ----------- LIABILITIES: Payable for fund shares redeemed ............. 22 6 - Distribution fees payable (Note 2) ........... 86 3 7 Dividends payable ............................ 5 - - Administrative services fees payable (Note 2) .......................... 234 3 5 Other liabilities ............................ 30 6 4 ------------ ---------- ----------- TOTAL LIABILITIES ......................... 377 18 16 ------------ ---------- ----------- NET ASSETS ...................................... $ 413,072 $ 15,063 $ 26,729 ============ ========== =========== ANALYSIS OF NET ASSETS: Paid-in-capital .............................. 413,072 15,063 26,729 ------------ ---------- ----------- NET ASSETS ...................................... $ 413,072 $ 15,063 $ 26,729 ============ ========== =========== Shares outstanding (no par value): Mileage Class: ............................... 46,534,448 9,517,758 22,669,979 ============ ========== =========== Platinum Class: .............................. 366,537,501 5,545,607 4,058,830 ============ ========== =========== Net asset value, offering and redemption price per share: Mileage Class: ............................... $ 1.00 $ 1.00 $ 1.00 ============ ========== =========== Platinum Class: .............................. $ 1.00 $ 1.00 $ 1.00 ============ ========== =========== See accompanying notes - -------------------------------------------------------------------------------- 11 AMERICAN BEACON MILEAGE FUNDS STATEMENTS OF OPERATIONS Six Months Ended June 30, 2005 (Unaudited) ================================================================================ U.S. GOVERNMENT MUNICIPAL MONEY MARKET MONEY MARKET MONEY MARKET ============ =============== ============ (IN THOUSANDS) INVESTMENT INCOME ALLOCATED FROM PORTFOLIO: Interest income ............................... $6,045 $201 $362 Portfolio expenses ............................

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 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"). The Funds commenced active operations on November 1, 1995. The U.S. Government Money Market and Municipal Money Market Mileage Funds commenced sales of a second class of shares designated as "Platinum Class" on November 1, 1999. At the same time, the existing shares of the U.S. Government Money Market and Municipal Money Market Mileage Funds were redesignated as "Mileage Class" shares. 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: AMERICAN BEACON: -> INVESTS ASSETS IN -> AMERICAN BEACON MASTER TRUST: - ------------------- ----------------------------- 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 Each American Beacon Master Trust Portfolio has the same investment objectives as its corresponding Fund. The value of such investment reflects each Fund's proportionate interest in the net assets of the corresponding portfolio (5.72%, 7.83% and 84.67% at June 30, 2005 of the American Beacon Master Trust Money Market, U.S. Government Money Market and Municipal Money Market Portfolios, respectively) (each a "Portfolio" and collectively the "Portfolios"). The financial statements of the Portfolios are included elsewhere in this report and should be read in conjunction with the Funds' financial statements. American Beacon Advisors, Inc. (the "Manager") 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 and Dividends to Shareholders Each Fund records its share of net investment income (loss) and realized gain (loss) in the Portfolio each day. All net investment income (loss) and realized gain (loss) of each Portfolio are allocated pro rata among the corresponding Fund and other investors in each Portfolio at the time of such determination. The Funds generally declare dividends daily from net investment income and net short-term capital gain, if any, payable monthly. Dividends to shareholders are determined in accordance with federal income tax principles that may treat certain transactions differently than U.S. generally accepted accounting principles. - -------------------------------------------------------------------------------- 16 AMERICAN BEACON MILEAGE FUNDS NOTES TO FINANCIAL STATEMENTS - CONTINUED June 30, 2005 (Unaudited) ================================================================================ 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 applicable to regulated investment companies 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. All dividends paid by the Municipal Money Market Mileage Fund were "exempt - interest dividends" and therefore are 100% free of any regular federal income tax. Approximately 22% of interest earned was derived from investments in certain private activity bonds for purposes of the federal alternative minimum tax calculation. 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. - -------------------------------------------------------------------------------- 17 AMERICAN BEACON MILEAGE FUNDS NOTES TO FINANCIAL STATEMENTS - CONTINUED June 30, 2005 (Unaudited) ================================================================================ 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. 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 other expenses through February 28, 2006 to the extent that total annual fund operating expenses exceed 1.20%. In addition, the Manager agreed to voluntarily reimburse additional fees to the extent necessary to preserve a certain minimum level of returns for Platinum Class Fund shareholders. During the six months ended June 30, 2005, the Manager waived or reimbursed expenses as follows: FUND AMOUNT - ---- ------ U.S. Government Money Market Mileage Fund Platinum Class ............................................... $5,577 Municipal Money Market Mileage Fund Platinum Class .............. 2,337 Expense Reimbursement Plan The Funds have adopted an Expense Reimbursement Plan whereby the Manager may seek repayment of fees waived or expenses reimbursed for a period of up to three years. However, reimbursement will occur only if the Class' average net assets have grown or expenses have declined sufficiently to allow reimbursement without causing its expense ratio to exceed the previously agreed upon contractual expense limit. The following waived fees or reimbursed expenses are subject to potential recovery expiring in: 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 ........ - 5,577 2,337 - -------------------------------------------------------------------------------- 18 AMERICAN BEACON MILEAGE FUNDS NOTES TO FINANCIAL STATEMENTS - CONTINUED June 30, 2005 (Unaudited) ================================================================================ Other Certain officers or Trustees of the Trust are also current or former officers or employees of the Manager or American. The Trust makes no direct payments to its officers. Mr. Feld and the non-interested Trustees (other than Mr. O'Sullivan) and their spouses are provided free unlimited air transportation on American. Retired Trustees and their spouses are provided free transportation on American, up to a maximum annual value of $40,000. The Trust compensates each Trustee with payments in an amount equal to the Trustee's income tax on the value of this free airline travel. Mr. O'Sullivan, as a retiree of American, already receives flight benefits. This Trustee receives an annual retainer of $40,000 plus $1,250 for each Board meeting attended. 3.

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 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 fair value, which approximates amortized cost. 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. 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. - -------------------------------------------------------------------------------- 36 AMERICAN BEACON MASTER TRUST NOTES TO FINANCIAL STATEMENTS - CONTINUED June 30, 2005 (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 Portfolios to lend money to other participating series managed by the Manager. For the six months ended June 30, 2005, the Money Market Portfolio earned $703 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. - -------------------------------------------------------------------------------- 37 RENEWAL OF MANAGEMENT AGREEMENTS (Unaudited) ================================================================================ At their February 23, 2005 meeting, the Trustees considered the renewal of the existing Management Agreement between the Manager and the Funds. As part of the renewal process, legal counsel to the Trusts and the independent Trustees sent information request letters to the Manager seeking certain relevant information. The response by the Manager was provided to the Trustees for their review prior to their meeting, and the Trustees were provided with the opportunity to request any additional materials. The Trustees considered, among other materials, response by the Manager to inquiries requesting: o 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; o a copy of the most recent audited or unaudited financial statements as well as Parts I and II of its Form ADV; o 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; o a comparison of the performance of each Fund with performance of other similar accounts managed by the Manager, including a discussion of relative performance versus a peer group average and any remedial measures if the Manager's performance was materially below that of the peer group; o 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; o 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; o an evaluation of any other benefits to the Manager or Funds as a result of their relationship, if any; o 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; o a description of the personnel who are assigned primary responsibility for managing the Fund, including any changes during the past year; o a description of the basis upon which portfolio managers are compensated, including any "incentive" arrangements; o a description of any actual or potential conflicts of interest anticipated in managing Fund assets; o a discussion regarding the Manager's participation in "soft dollar" arrangements, if any, or other brokerage allocation policies with respect to Fund transactions, including the Manager's methodology for obtaining the most favorable execution and the use of any affiliated broker-dealers; o a description of trade allocation procedures among accounts managed by the Manager; o a discussion of the Manager's compliance program with regard to federal, state, corporate and Fund requirements; - -------------------------------------------------------------------------------- 38 RENEWAL OF MANAGEMENT AGREEMENTS (Unaudited) - (Continued) ================================================================================ o information regarding the Manager's code of ethics, insider trading policy and disaster recovery plan, including a description of any material changes thereto; o a description of the Manager's affiliation with any broker-dealer; o a discussion of any anticipated change in the Manager's controlling persons; o verification of the Manager's insurance coverage with regards to the services provided to the Funds; o a table comparing the performance of each Fund to appropriate indices, including comments on each Fund's relative performance; o a table detailing the Manager's profitability with respect to each Fund; o an analysis of any material complaints received from Fund shareholders; o a description of how expenses that are not readily identifiable to a particular Fund are allocated; and o any ideas for the future growth and efficient operation of the Funds. The Trustees were also provided with an analysis provided by Lipper, Inc., which compared: (i) investment performance of each Fund versus comparable investment companies and appropriate indices; (ii) total expenses of each Fund versus comparable mutual funds, and (iii) each Fund's investment advisory fees versus comparable mutual funds. Legal counsel provided the Trustees with a memorandum detailing their responsibilities pertaining to the renewal of the Management Agreements. This memorandum explained the regulatory requirements surrounding the Trustees' process for evaluating investment advisors and the terms of the contracts. CONSIDERATIONS WITH RESPECT TO ALL FUNDS - ---------------------------------------- In determining whether to approve the continuance of the Management Agreement, the Trustees considered the best interests of each Fund separately. In each instance, the Trustees considered, among other things, the following factors: (1) the nature and quality of the services provided; (2) the investment performance of the Fund and the Manager; (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. With respect to the renewal of the Management Agreement, the Trustees 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 continue to provide consistent above average long-term performance at low cost; the continuing efforts by the Manager to add new series so as to enhance the Trust's 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. ADDITIONAL CONSIDERATIONS WITH RESPECT TO THE MONEY MARKET MILEAGE FUND - ----------------------------------------------------------------------- In considering the renewal of the Management Agreement, the Trustees considered the following additional factors: (1) the Money Market Mileage Fund - Mileage Class had substantially above-average performance for all reported periods ended December 31, 2004; (2) the management fees for the Money Market Mileage Fund were lower than the average of the Fund's peer group and other comparable funds, - -------------------------------------------------------------------------------- 39 RENEWAL OF MANAGEMENT AGREEMENTS (Unaudited) - (Continued) ================================================================================ although total expense ratios of the Mileage and Platinum Classes were higher than their peers; (3) the Trustees deemed the profit made by the Manager on the services it provided to the Fund to be reasonable in light of the fact that the Manager provides high-quality services at a low cost to investors, manages the Fund's assets, is subject to a high degree of risk of financial responsibility should the Fund be unable to maintain its stable $1.00 per share net asset value and provides a comprehensive compliance program for the Fund; (4) 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; and (5) the Manager has contractually agreed to continue to waive fees and/or reimburse Fund expenses to the extent necessary to maintain a competitive total expense ratio for the Platinum Class of shares of the Fund. Based on these considerations and those noted above with respect to all Funds, the Trustees (1) concluded that the fees paid to the Manager under the Management Agreement are fair and reasonable, (2) determined that the Money Market Mileage Fund and its shareholders would benefit from the Manager's continued management of the Fund and (3) approved the renewal of the Management Agreement with respect to the Money Market Mileage Fund. ADDITIONAL CONSIDERATIONS WITH RESPECT TO THE MUNICIPAL MONEY MARKET MILEAGE - ---------------------------------------------------------------------------- FUND - ---- In considering the renewal of the Management Agreement, the Trustees considered the following additional factors: (1) the Municipal Money Market Mileage Fund - Mileage Class matched the performance of its peer group for the one-year period ended December 31, 2004, but underperformed its peer group for longer periods primarily due to its relatively higher expense ratio; (2) the management fees for the Municipal Money Market Mileage Fund were lower than the average of the Fund's peer group and other comparable funds, although the total expense ratio was higher than its peers; (3) the Manager incurred a loss on the services it provided to the Fund; (4) the Manager provides high-quality services at a low cost to investors, manages the Fund's assets, is subject to a high degree of risk of financial responsibility should the Fund be unable to maintain its stable $1.00 per share net asset value and provides a comprehensive compliance program for the Fund; (5) 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; and (6) the Manager has contractually agreed to continue to waive fees and/or reimburse Fund expenses to the extent necessary to maintain a competitive total expense ratio for the Platinum Class of shares of the Fund. Based on these considerations and those noted above with respect to all Funds, the Trustees (1) concluded that the fees paid to the Manager under the Management Agreement are fair and reasonable, (2) determined that the Municipal Money Market Mileage Fund and its shareholders would benefit from the Manager's continued management of the Fund and (3) approved the renewal of the Management Agreement with respect to the Municipal Money Market Mileage Fund. ADDITIONAL CONSIDERATIONS WITH RESPECT TO THE U.S. GOVERNMENT MONEY MARKET - -------------------------------------------------------------------------- MILEAGE FUND - ------------ In considering the renewal of the Management Agreement, the Trustees considered the following additional factors: (1) the U.S. Government Money Market Mileage Fund-Mileage Class outperformed its peer group for the one-year period ended December 31, 2004, but under performed its peer group for longer periods primarily due to its relatively higher expense ratio; (2) the management fees for the U.S. Government Money Market Mileage Fund were lower than the average of the Fund's peer group and other comparable funds, although total expense ratios of the Mileage and Platinum Classes were higher than their peers; (3) the Manager incurred a loss on the services it provided to the Fund; (4) the Manager provides high-quality services at a low cost to investors, manages the Fund's assets, is subject to a high - -------------------------------------------------------------------------------- 40 RENEWAL OF MANAGEMENT AGREEMENTS (Unaudited) - (Continued) ================================================================================ degree of risk of financial responsibility should the Fund be unable to maintain its stable $1.00 per share net asset value and provides a comprehensive compliance program for the Fund; (5) 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; and (6) the Manager has contractually agreed to continue to waive fees and/or reimburse Fund expenses to the extent necessary to maintain a competitive total expense ratio for the Platinum Class of shares of the Fund. Based on these considerations and those noted above with respect to all Funds, the Trustees (1) concluded that the fees paid to the Manager under the Management Agreement are fair and reasonable, (2) determined that the U.S. Government Money Market Mileage Fund and its shareholders would benefit from the Manager's continued management of the Fund and (3) approved the renewal of the Management Agreement with respect to the U.S. Government Money Market Mileage Fund. - -------------------------------------------------------------------------------- 41 (This page intentionally left blank) (This page intentionally left blank) (This page intentionally left blank) [LOGO OF AMERICAN BEACON MILEAGE FUNDS] AMERICAN BEACON MILEAGE FUNDS(SM) ================================================================================ DELIVERY OF DOCUMENTS To reduce expenses, your financial institution may mail only one copy of the Prospectus, Annual Report and Semi-Annual Report to those addresses shared by two or more accounts.
