Notes

Hypothetical, historical performance measures: Represent the performance of the ETF Efficiente Index based on, as applicable to the relevant measurement period, the hypothetical backtested daily closing levels through October 28, 2010, and the actual historical performance of the ETFs based on the daily closing level from October 29, 2010 through September 30, 2014, as well as the performance of the S&P 500 Index (Excess Return), and the Barclays Aggregate Bond Index (Excess Return) over the same periods. 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 ETF Efficiente Index will outperform the S&P 500 Index (Excess Return), the Barclays Aggregate Bond Index (Excess Return) or any alternative investment strategy. Sources: Bloomberg and JPMorgan.

S&P 500 Index (Excess Return) represents a hypothetical index constructed from the total returns of the S&P 500 Index with the returns of the Cash Index deducted. Barclays Aggregate Index (Excess Return) represents a hypothetical index constructed from the returns of the Barclays Aggregate Index with the returns of the Cash Index deducted.

Volatility: hypothetical, historical six-month annualized volatility levels are presented for informational purposes only. Volatility levels are calculated from the historical returns, as applicable to the relevant measurement period, of the ETF Efficiente, S&P 500 Index (Excess Return), and the Barclays Aggregate Bond Index (Excess Return).

Volatility represents the annualized standard deviation of the relevant index’s arithmetic daily returns since September 30, 2004. The Sharpe Ratio, which is a measure of risk-adjusted performance, is computed as the ten year annualized historical return divided by the ten year annualized volatility.

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 ETF Efficiente Index (the “Strategy”) is different from a strategy that seeks long-term exposure to a portfolio consisting of constant components with fixed weights. The Strategy 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 basket constituents may reduce the performance of strategy—performances among the basket constituents comprising the index from time to time (the “Basket Constituents”) may become highly correlated from time to time during the term of your investment. High correlation during periods of negative returns among Basket 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 Strategy.

■   Our affiliate, JPMS PLC, is the Calculation Agent and may adjust the Index in a way that affects its level—The policies and judgments for which JPMSL is responsible could have an impact, positive or negative, on the level of the Index and the value of your investment. JPMSL 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 Basket Constituents, or may not achieve its target volatility of 5%.

■   The investment strategy involves monthly rebalancing and maximum weighting caps applied to the Basket Constituents by asset type and geographical region that may reduce your return.

■   Changes in the value of the Basket 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 was established on October 29, 2010 and has a limited operating history

■   The Index may be partially uninvested. Any uninvested portion will earn no return.

■   The Index has an adjustment factor fee, which causes the Index to trail the value of a hypothetical identically constituted synthetic portfolio without a similar fee.
