2008 Year-To-Date Return:1 -43.60%

Unit values reflect the close-of-business unit value for each date shown.

1"2008 Year-To-Date Return" reflects the actual time weighted rate of return for the Portfolio from 12/31/07 through and including the most recent date for which a unit value is shown. Fees, which can vary by client, are charged to the participating plan and not to the Portfolio. This representation of performance is not intended to reflect the actual performance an account could have experienced after the deduction of fees. The deduction of fees and the compounding effect of such deductions over time will reduce a client's return. For example, an account with a 2.5% fee deducted quarterly and a 20% gross annualized performance will have net performance after fees of about 17% per year, a reduction of 3% per year. Compounding will similarly affect the account's performance on a cumulative basis, as will timing and other individual account factors. No representation as to future results can be made from past performance.
