North America Structured Investments 3yr Auto Callable Review Notes Selected Benefits [] Fixed appreciation potential [] Potential early exit with appreciation as a result of automatic call feature. Selected Risks [] Your investment in the notes may result in a loss. The notes do not guarantee any return of principal. [] Any payment on the notes is subject to our credit risk. Therefore the value of the notes prior to maturity are subject to changes in the market's view of our creditworthiness. [] You are exposed to the risks of the decline in value of each Index. [] Your payment at maturity may be determined by the lesser performing Index. [] Return is limited to the principal amount plus call premium regardless of any appreciation of the Indices, which may be significant. [] If the notes have not been automatically called and a Trigger Event has occurred, you will lose 1% of your principal for every 1% the final level of the lesser performing Underlying is less than its Initial Level. [] The benefit provided by the Contingent Buffer Amount may terminate on the Final Review Date. [] The automatic call feature may force a potential early exit. There is no guarantee you will be able to reinvest the proceeds at a comparable interest rate for a similar level of risk. [] No interest or dividend payments, voting rights, or ownership rights with the securities included in the Index. [] You are exposed to the risks associated with small capitalization companies. Selected Risks (continued) [] JPMS' estimated value does not represent future values and may differ from others' estimates. [] The notes' value which may be reflected in customer account statements may be higher than JPMS' then current estimated value. [] JPMS' estimated value is not determined by reference to our credit spreads for our conventional fixed rate debt. [] Lack of liquidity: JPMorgan Securities, LLC, acting as agent for the Issuer (and who we refer to as JPMS), intends to offer to purchase the notes in the secondary market but is not required to do so. The price, if any, at which JPMS will be willing to purchase notes from you in the secondary market, if at all, may result in a significant loss of your principal. [] Potential conflicts: we and our affiliates play a variety of roles in connection with the issuance of notes, including acting as calculation agent, hedging our obligations under the notes and making the assumptions to determine the pricing of the notes and the estimated value of the notes when the terms of the notes are set. It is possible that such hedging or other trading activities of JPMorgan or its affiliates could result in substantial returns for JPMorgan and its affiliates while the value of the notes decline. [] The tax consequences of the notes may be uncertain. You should consult your tax adviser regarding the U. S. federal income tax consequences of an investment in the notes. The risks identified above are not exhaustive.
