North America Structured Investments 5yr EFA/SX5E Uncapped Accelerated Barrier Note Selected Risks •Your investment in the notes may result in a loss. •Payment on the notes at maturity is subject to the credit risk of JPMorgan Chase Financial Company LLC and JPMorgan Chase & Co. Therefore the value of the notes prior to maturity will be subject to changes in the market’s view of the creditworthiness of JPMorgan Chase Financial Company LLC or JPMorgan Chase & Co. •If the Final Value is less than the Initial Value by more than the Contingent Buffer Amount, you will lose 1% of the principal amount of your notes for every 1% that the Final Value is less than the Initial Value. Accordingly, under these circumstances, you will lose more than 50.00% of your principal amount at maturity and could lose all of your principal amount at maturity. •No interest payments, dividend payments or voting rights. •The tax consequences of the notes may be uncertain. You should consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the notes. •As a finance subsidiary, JPMorgan Chase Financial Company LLC has no independent operations and has limited assets. •J.P. Morgan is currently one of the companies that makes up the S&P 500 Index. •The notes are subject to the risks associated with small capitalization stocks. •You are exposed to the risk of decline in the level of each Index. Selected Risks (continued) •The estimated value of the notes will be lower than the original issue price (price to public) of the notes. •You are exposed to the risks associated with small capitalization companies. •The estimated value of the notes is determined by reference to an internal funding rate. •The estimated value of the notes does not represent future values and may differ from others’ estimates. •The value of the notes, which may be reflected in customer account statements, may be higher than the then current estimated value of the notes for a limited time period. •Lack of liquidity: J.P. Morgan 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 and hedging our obligations under the notes, and making the assumptions used 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 J.P. Morgan or its affiliates could result in substantial returns for J.P. Morgan and its affiliates while the value of the notes decline.
