Source: J.P. Morgan. Past performance is not a guide to future performance. "JPUSSC8E Index" refers to the performance of J.P. Morgan U.S. Sector Rotator 8 Index (Bloomberg: JPUSSC8E Index). The levels of the Index incorporate an adjustment factor of 0.50% per annum. Hypothetical, historical performance measures: Represents the monthly and full calendar year performance of the Index based on as applicable to the relevant measurement period, the hypothetical back tested daily closing levels from December 31, 2003 through June 28, 2013, and the actual historical performance of the Index based on daily closing levels from July 1, 2013 through June 30, 2014. The hypothetical historical values above have not been verified by an independent third party. The back-tested, hypothetical historical results above have inherent limitations. These back-tested results are achieved by means of a retroactive application of a back-tested model designed with the benefit of hindsight. No representation is made that an investment linked to the Index will or is likely to achieve returns similar to those shown. Alternative modelling techniques or assumptions would produce different hypothetical historical information that might prove to be more appropriate and that might differ significantly from the hypothetical historical information set forth above. Hypothetical back-tested results are neither an indicator nor a guarantee of future returns. Actual results will vary, perhaps materially, from the analysis implied in the hypothetical historical information that forms part of the information contained in the table above. 1

Key Risks [] The Strategy comprises notional assets and liabilities [] The Index may use leverage to increase the return from any Constituent because the sum of the weights of the Basket Constituents included in the synthetic portfolio underlying the Index may be greater than 100%, up to a maximum total weight of 220%.
