For purposes of these examples, each index was set equal to 100 at the beginning of the relevant measurement period and returns are calculated arithmetically (not compounded). The "SandP 500 Index (Excess Return)" and "Barclays Aggregate Bond Index (Excess Return)" refer to hypothetical indices constructed from the total returns of the relevant index with the returns of the Cash Index deducted. There is no guarantee the Efficiente Plus 5 Index will outperform the SandP 500 Index (Excess Return), the Barclays Aggregate Bond Index (Excess Return) or any alternative investment strategy. Sources: Bloomberg and JPMorgan. Correlation: the performance of the relevant index to the Efficiente Plus 5 Index, calculated based on the daily returns since November 1, 2007. Volatility: the annualized standard deviation of the relevant index's arithmetic daily returns since May 2, 2008. Volatility levels are calculated from the hypothetical and historical returns, as applicable to the relevant measurement period, of the Efficiente Plus 5 Index, SandP 500 Index (Excess Return), and the Barclays Aggregate Bond Index (Excess Return)." Sharpe Ratio: a measure of risk-adjusted performance, and is computed as the annualized hypothetical and historical return since November 1, 2007 divided by the annualized volatility since November 1, 2007. For time periods prior to the launch of any Exchange-Traded Constituent and such Exchange-Traded Constituents' initial satisfaction of a minimum size and liquidity standard, the hypothetical back-testing uses alternative performance information derived from a related index, after deducting hypothetical expenses and fees, rather than performance information for such ETF. The back-tested, hypothetical, historical annualized volatility and index returns have inherent limitations. These volatility and return results were achieved by means of a retroactive application of a back-tested volatility model designed with the benefit of hindsight. No representation is made that in the future the relevant indices will have the volatility or return results shown. Alternative modeling techniques or assumptions might produce significantly different results and may prove to be more appropriate. Actual annualized volatilities and returns may vary materially from this analysis. Source: Bloomberg and JPMorgan. Key Risks Our affiliate, J.P.
