Source: J.P. Morgan. Past performance is not a guide to future performance. "EFPLUS5D Index" refers to the performance of J.P. Morgan Efficiente Plus DS 5 Index (Net ER) (Bloomberg: EFPLUS5D Index)(the "Index"). The levels of the Index incorporate a fee of 0.85% 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, 2007 through December 31, 2014, and the actual historical performance of the Index based on daily closing levels from January 1, 2015 through June 30, 2015. YTD reflects the year to date performance of the Index from the last business day of the previous calendar year through, and including June 30, 2015. 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. GRAPHIC OMMITTED
