Moody's ranks five American AAdvantage Funds

AMR Investments, manager of the American AAdvantage Funds, is proud to announce that Moody's Investors Service assigned Aaa money market fund ratings to the American AAdvantage Money Market Select Fund, the American AAdvantage Money Market Fund - Cash Management Class, the American AAdvantage Money Market Fund - Institutional Class, American AAdvantage U.S. Government Money Market Select Fund and the American AAdvantage U.S. Government Money Market Fund - Cash Management Class.

Moody's stated that the Aaa ratings reflect the strong overall credit quality of each fund's investments, solid liquidity management, as well as the conservative investment guidelines and practices of the advisor, AMR Investment Services, Inc. of Fort Worth, Texas. These "feeder funds" operate under a "master/feeder" structure and invest all assets in the Aaa rated AMR Investment Services Money Market and U.S. Government Money Market Portfolios, respectively.

In support of its ratings, Moody's cited AMR Investments' policies designed to control credit risk, market risk and cash flow volatility. Moody's also noted that AMR Investments is an experienced fund sponsor with well developed trading, audit, and compliance systems.

Bill Quinn, president of AMR Investments stated, "We are very pleased with the ratings assigned by Moody's to these funds as it recognizes the commitment we have made to providing a very high quality investment vehicle to our shareholders."
