*Source: Parametric. For illustration purposes only. Performance is presented for the Parametric Custom Core U.S. Large Cap 2007 Vintage Composite which consists of accounts that completed their first full month of activity in 2007; the Composite’s inception date is 12/31/2006. The Composite consists of fully discretionary accounts incepted in cash, free of unique investment guidelines or restrictions, and have not changed their benchmark. The Composite was selected for presentation because it is the youngest Vintage Composite with ten full years of performance. It was not selected based on its performance. The returns are presented net (35bps) of advisory fees and brokerage commissions. Performance reflects the reinvestment of dividends and other earnings. Benchmark after-tax returns are simulated for each client portfolio using client-specific, after-tax benchmark portfolios. Performance of the after-tax benchmark is simulated using the same inception date, cash flows, cost basis, and tax rates as the client portfolio. The after-tax benchmark’s capital gain realization rate is based on the average turnover rate of the pre-tax benchmark and ending gain or loss of the after-tax benchmark for each period. The dividend income is estimated using the pre-tax benchmark index’s dividend return during the period. After-tax benchmark returns reflect the deduction of taxes, but do not include any other fees or expenses. After-tax benchmark returns are hypothetical, do not reflect actual trading, and may not be relied upon for investment decisions. The index is provided for comparison purposes. It is not possible to invest directly in an index. Past performance is not indicative of future results. All investments are subject to the risk of loss.
