S and P 500[R] Dividend Aristocrats Risk Control 8% Exces s Return Index Performance Update - March 2013 OVERVIEW The S and P 500[R] Dividend Aristocrats Risk Control 8% Excess Return Index (the "Index") provides investors with exposure to the "blue chip" names of the S and P 500[R] Dividend Aristocrats Total Return Index. It also adds a volatility control mechanism that targets 8% volatility by adjusting its level of exposure to the S and P 500[R] Dividend Aristocrats Total Return Index. This volatility control mechanism seeks to create a more consistent risk-return profile for the Dividend Aristocrats Risk Control 8% Index. Key Features of the Index [] Exposure to the S and P 500[R] Dividend Aristocrats Total Return Index, a group of 40 or more S and P 500[R] stocks with records of consistently increasing dividends over the past 25 years. S and P can relax this criterion if less than 40 names qualify. [] In an effort to maintain a constant annualized volatility of 8%, the Index uses an algorithm to dynamically adjust exposure daily. [] To adjust exposure, the Index has the ability to employ leverage of up to 150% during periods of low volatility. [] Levels published daily by Standard and Poor's on Bloomberg. The S and P 500[R] Dividend Aristocrats Risk Control 8% Excess Return Index targets 8% volatility and is published to Bloomberg under the ticker SPXD8UE.

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 relevant Index will outperform the S and P 500[R] Total Return Index, the S and P 500[R] Dividend Aristocrats Total Return Index or any alternative investment strategy. Sources: Bloomberg and JPMorgan.Volatility is calculated from the historical returns, as applicable to the relevant measurement period, of the S and P 500[R] Total Return Index, the S and P 500[R] Dividend Aristocrats Total Return Index and the S and P 500[R] Dividend Aristocrats Risk Control 8% Excess Return Index. Volatility represents the annualized standard deviation of the relevant index's arithmetic daily returns through February 28, 2013. The index leverage is the hypothetical back-tested amount of exposure of the Index to the S and P 500[R] Dividend Aristocrats Total Return Index and should not be considered indicative of the actual leverage that would be assigned during an investment in the Index. 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 leverage have inherent limitations. These volatility and leverage 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 as shown. Alternative modeling techniques or assumptions might produce significantly different results and may prove to be more appropriate. Actual annualized volatilities and leverage may vary materially from this analysis. Source: Bloomberg and JPMorgan. Key Risks [] The Index has a limited operating history and may perform in unexpected ways. The Index began publishing on August 25, 2010 and, therefore, has a limited history. S and P has calculated the returns that hypothetically might have been generated had the Index existed in the past, but those calculations are subject to many limitations and do not reflect actual trading, liquidity constraints, fees and other costs. [] The Index may not be successful, may not outperform the S and P 500[R] Dividend Aristocrats Total Return Index and may not achieve its target volatility. No assurance can be given that the volatility strategy will be successful or that the Index will outperform the S and P 500[R] Dividend Aristocrats Total Return Index or any alternative strategy that might be employed to reduce the level of risk of the S and P 500[R] Dividend Aristocrats Total Return Index . We also can give no assurance that the Index will achieve its target volatility of 8%. [] The Index is not a total return index, and is subject to short-term money market fund borrowing costs-- As an "excess return" index, the S and P 500[R] Dividend Aristocrats Risk Control 8% Excess Return Index calculates the return on a leveraged or deleveraged investment in the S and P 500[R] Dividend Aristocrats Total Return Index where the investment was made through the use of borrowed funds. Investments linked to this "excess return" index, which represents an unfunded position in the S and P 500[R] Dividend Aristocrats Total Return Index , will be subject to short-term money market fund borrowing costs and will not include the "total return" feature or the cash component of the "total return" index, which represents a funded position in the S and P 500[R] Dividend Aristocrats Total Return Index . [] The Index represents portfolios consisting of the S and P 500[R] Dividend Aristocrats Total Return Index and a borrowing cost component accruing interest based on a synthetically rolling 3-month bond with reference to the 2-month and 3-month U.S. LIBOR rates. The Index dynamically adjusts its exposures to the S and P 500[R] Dividend Aristocrats Total Return Index based on the S and P 500[R] Dividend Aristocrats Total Return Index's historic volatility. The Index's' exposure to the S and P 500[R] Dividend Aristocrats Total Return Index will decrease when historical volatility causes the risk level of the S and P 500[R] Dividend Aristocrats Total Return Index to reach a high threshold. If, at any time, the Index exhibits low exposure to the S and P 500[R] Dividend Aristocrats Total Return Index and the S and P 500[R] Dividend Aristocrats Total Return Index subsequently appreciates significantly, the Index will not participate fully in this appreciation.
