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). There is no guarantee the JPMorgan ETF Efficiente 10 TR Series X Index will outperform the SandP 500 Total Index, the Barclays U.S. Aggregate Bond Index (Total Return) or any alternative investment strategy. Sources: Bloomberg and JPMorgan. SandP 500 Total Return Index represents the total returns of the SandP 500 Index. Barclays U.S. Aggregate Bond Index (Total Return) represents the returns of the Barclays U.S. Aggregate Bond Index Volatility: hypothetical, historical annualized volatility levels are presented for informational purposes only. Volatility levels are calculated from the hypothetical returns, as applicable to the relevant measurement period, of the JPMorgan ETF Efficiente 10 TR Series X, SandP 500 Total Return Index, and the Barclays Aggregate Bond Index. Volatility represents the annualized standard deviation of the relevant index's arithmetic daily returns since December 31, 2007. The Sharpe Ratio, which is a hypothetical measure of risk-adjusted performance, is computed as the annualized historical return since December 31, 2007 divided by the annualized volatility since December 31, 2007. Correlation : Correlation refers to the performance of the relevant index to the JP Morgan ETF Efficiente 10 TR Series X Index. The back-tested, hypothetical, historical annualized volatility and index returns may use substitutes for any ETF that was not in existence or did not meet the liquidity standards at that particular time. 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 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 There are risks associated with a momentum-based investment strategy--The JPMorgan ETF Efficiente 10 TR Series X Index (the "Index") is different from a strategy that seeks long-term exposure to a portfolio consisting of constant components with fixed weights. The Index may fail to realize gains that could occur from holding assets that have experienced price declines, but experience a sudden price spike thereafter. Correlation of performances among the constituents may reduce the performance of the Index--performances among the constituents comprising the index from time to time (the "Constituents") may become highly correlated from time to time during the term of your investment. High correlation during periods of negative returns among Constituents representing any one sector or asset type that have a substantial weighting in the Strategy could have a material adverse effect on the performance of the Index. Our affiliate, JPMS plc, is the Index sponsor and may adjust the Index in a way that affects its level--The policies and judgments for which JPMS plc is responsible could have an impact, positive or negative, on the level of the Index and the value of your investment. JPMS plc is under no obligation to consider your interest as an investor with returns linked to the Index. The Index may not be successful, may not outperform any alternative strategy related to the Constituents, or may not achieve its target volatility of 10%. The investment strategy involves monthly rebalancing and maximum weighting caps applied to the Constituents by asset type and geographical region that may reduce your return. Changes in the value of the Constituents may offset each other. An investment linked to the Index is subject to risks associated with non-U.S. securities markets, such as emerging markets and currency exchange risk. The Index comprises notional assets and liabilities. There is no actual portfolio of assets to which any person is entitled or in which any person has any ownership interest. The Index was established on September 29, 2014 and has a limited operating history. The risks identified above are not exhaustive.
