These performance returns represent the individual monthly performances (so the closing level of the previous month is used as the starting level of the subsequent month) and reflect the deduction of the 0.80% bps p.a. adjustment factor. *Past performance and back-tested performance are not indicative of future results Investment Styles [] Momentum: Aims to exploit the observed tendency of many markets to trend up or down for sustained periods of time. [] Carry: Seeks to capitalize on the value differential between certain assets and is typically implemented by notionally buying an asset that is on a relative basis higher yielding (or lower priced) and selling an asset that is lower yielding (or higher priced). [] Satellite: Consists of mean reversion and short volatility strategies. Mean reversion seeks to capitalize on the view that over the short term markets are cyclical -- meaning that an upward trend is usually followed by a downward trend and vice versa. Short volatility aims to exploit the observed tendency of the implied volatility of an equity index to be higher than the volatility realized by the index. February 06, 2013

For more information on the Index and for additional key risk information see Page 9 the Strategy Guide at: http://www.sec.gov/Archives/edgar/data/19617/000095010312004030/crt_dp32126-fwp ..pdf Key Risks: Any securities we may issue linked to the Index may result in a loss, and are exposed to J.P. Morgan Chase and Co. credit risk. The Index and underlying strategies have limited operating history. The reported level of the Index and most of the underlying strategies will include the deduction of an adjustment factor. The Index may not be successful, may not outperform any alternative strategy or achieve its 5% target volatility. The portfolio of underlying strategies may not be a diversified portfolio. The Index involves monthly rebalancing and caps the sum of the weights of all underlying strategies, at rebalance, to 200%. It is possible, although unlikely, for the weight of a single underlying strategy to be close to 200%. There are risks associated with momentum, carry, mean reversion or short volatility investment strategies. The Index comprises only notional assets and liabilities. Some underlying strategies include notional short positions. Correlation of performances among the underlying strategies may reduce the performance of the Index. The Index is an excess return index and reflects the performance of unfunded or uncollateralized investments in the assets underlying the Index. Commodity futures contracts underlying some of the strategies are subject to uncertain legal and regulatory regimes. Our affiliate, J.P. Morgan Securities plc ("JPMS plc"), is the Sponsor and Calculation Agent for the Index and underlying strategies. JPMS plc may adjust the Index or any underlying strategy in a way that affects its level. The Index is subject to risks associated with currency exchange, interest rates, non-US securities markets and the use of leverage and futures contracts.
