J.P. Morgan Structured Investments | 1 800 576 3529 | jpm_structured_investments@jpmorgan.com Selected Risks • The notes may not pay more than 95.00% of the principal amount at maturity. • Any payment on the notes is subject to the credit risks 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. • No interest payments, dividend payments or voting rights. • The notes are subject to the risks associated with non - U.S. securities. • The notes do not provide direct exposure to fluctuations in foreign exchange rates. • As a finance subsidiary, JPMorgan Chase Financial Company LLC has no independent operations and has limited assets. Selected Risks (continued) • The estimated value of the notes will be lower than the original issue price (price to public) of the notes. • 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 (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. • 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. The risks identified above are not exhaustive.
