Automatic Call

Review Date Call Value* Call Premium* First At most 102.00% At least  8.00% Second At most 104.00% At least  16.00% Third At most 106.00% At least  24.00% Fourth At most 108.00% At least  32.00% Fifth At most 110.00% At least  40.00% Sixth At most 112.00% At least  48.00%  

If the closing level of each Index on any Review Date (other than the final Review Date) is greater than or equal to its Call Value for that Review Date, the notes will be automatically called for a cash payment, for each $1,000 principal amount note, equal to (a) $1,000 plus (b) the Call Premium Amount applicable to that Review Date, payable on the applicable Call Settlement Date. No further payments will be made on the notes.

Payment At Maturity

If the notes have not been automatically called and the Final Value of each Index is greater than its Initial Value, your payment at maturity per $1,000 principal amount note will be calculated as follows:

$1,000 + ($1,000 × Lesser Performing Index Return)

If the notes have not been automatically called and (i) the Final Value of one Index is greater than its Initial Value and the Final Value of the other Index is equal to its Initial Value or is less than its Initial Value by up to the Buffer Amount or (ii) the Final Value of each Index is equal to its Initial Value or is less than its Initial Value by up to the Buffer Amount, you will receive the principal amount of your notes at maturity.

If the notes have not been automatically called and the Final Value of either Index is less than its Initial Value by more than the Buffer Amount, your payment at maturity per $1,000 principal amount note will be calculated as follows:

$1,000 + [$1,000 × (Lesser Performing Index Return + Buffer Amount)]

If the notes have not been automatically called and the Final Value of either Index is less than its Initial Value by more than the Buffer Amount, you will lose some or most of your principal amount at maturity.

* Reflects a call premium of 8.00% per annum and the applicable maximum Call Values listed in the table to the left. The call premium will be determined on the Pricing Date and will not be less than 8.00% per annum. The Call Values will be determined on the Pricing Date and will not be greater than the applicable maximum.

** Not all Review Dates reflected. The hypothetical returns on the notes shown above apply only if you hold the notes for their entire term or until automatically called. These hypotheticals do not reflect fees or expenses that would be associated with any sale in the secondary market. If these fees and expenses were included,

the hypothetical returns would likely be lower.

• 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 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.

• The Call Value with respect to each Index for each Review Date is greater than its

Initial Value and increases progressively over the term of the notes.

• If the notes are automatically called, the appreciation potential of the notes is limited to any Call Premium paid on the notes.

• You are exposed to the risk of decline in the level of each Index.

• Your payment at maturity will be determined by the Lesser Performing Index.

• The automatic call may force a potential early exit.

• No interest payments, dividend payments or voting rights.

• JPMorgan Chase & Co. 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 companies.

• 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. Please see “Risk Factors” in the applicable product supplement and underlying supplement and “Selected Risk Considerations” in the applicable preliminary pricing supplement for additional information.
