It should be noted that the majority of the products that include AHL are priced on a monthly basis and it is this pricing, therefore, that forms the basis of the majority of performance fees earned. However, the products that are priced on a weekly basis give a more up-to-date indication of the progress of AHL. It should also be noted that whilst the products that will be reported have been chosen to be indicative of the typical AHL product, the performance of the individual products do vary. The product that will be reported weekly will be AHL Diversified Futures Ltd. Its price is calculated based on the close of business each Monday and its price will be published after close of business London time on Tuesday of each week. The product that will be published on a monthly basis will be Athena Guaranteed Futures Ltd, which is priced based on the close of business on the last business day of each month. Its price will be released by 7am on the third business day of each month. Man will release the latest twelve month performance and the performance since inception figures for its representative AHL funds for comparative purposes, calculated using the last monthly valuation for each month.

The prices of this and other AHL products are also reported in the Financial Times and the International Herald Tribune, in addition to data services such as Reuters, Bloomberg, Micropal and Telekurs, as well as on the web site of Man Investments at www.maninvestments.com
