Total Contingent Interest Payments

The table below illustrates the hypothetical total Contingent Interest Payments per $1,000 principal amount note over the term of the notes based on a hypothetical Contingent Interest Rate of 10.50% per annum, depending on how many Contingent Interest Payments are made prior to early redemption or maturity. The actual Contingent Interest Rate will be provided in the pricing supplement and will be between 10.50% and 11.50% per annum.

Number of Contingent Interest Payments	Total Contingent Interest Payments

Hypothetical Payout Examples

The following examples illustrate payments on the notes linked to three hypothetical Underlyings, assuming a range of performances for the hypothetical Least Performing Underlying on the Review Dates and during the Quarterly Monitoring Periods. The hypothetical payments set forth below assume the following:

· the notes have not been redeemed early;

· an Initial Value for the Least Performing Underlying of 100.00;

PS-3 | Structured Investments Callable Contingent Interest Notes Linked to the Least Performing of the S&P 500^® Index, the Russell 2000^® Index and the iShares^® MSCI EAFE ETF

· an Interest Barrier for the Least Performing Underlying of 70.00 (equal to 70.00% of its hypothetical Initial Value);

· a Trigger Value for the Least Performing Underlying of 55.00 (equal to 55.00% of its hypothetical Initial Value); and

· a Contingent Interest Rate of 10.50% per annum (payable at a rate of 2.625% per quarter).

The hypothetical Initial Value of the Least Performing Underlying of 100.00 has been chosen for illustrative purposes only and may not represent a likely actual Initial Value of any Underlying. The actual Initial Value of each Underlying will be the closing value of that Underlying on the Pricing Date and will be provided in the pricing supplement. For historical data regarding the actual closing values of each Underlying, please see the historical information set forth under “The Underlyings” in this pricing supplement.

Each hypothetical payment set forth below is for illustrative purposes only and may not be the actual payment applicable to a purchaser of the notes. The numbers appearing in the following examples have been rounded for ease of analysis.

Example 1 — Notes have NOT been redeemed early, the Final Value of the Least Performing Underlying is greater than or equal to its Trigger Value and the closing value of the Least Performing Underlying on each day during the final Quarterly Monitoring Period is greater than or equal to its Interest Barrier.

Date	Closing Value of Least Performing Underlying on Review Date	Lowest Closing Value of Least Performing Underlying During Quarterly Monitoring Period	Payment (per $1,000 principal amount note)
First Review Date	95.00	90.00	$26.25
Second Review Date	85.00	80.00	$26.25
Third through Thirteenth Review Dates	Various	Less than Interest Barrier	$0
Final Review Date	90.00	90.00	$1,026.25
		Total Payment	$1,078.75 (7.875% return)

Because the notes have not been redeemed early, the Final Value of the Least Performing Underlying is greater than or equal to its Trigger Value and the closing value of the Least Performing Underlying on each day during the final Quarterly Monitoring Period is greater than or equal to its Interest Barrier, the payment at maturity, for each $1,000 principal amount note, will be $1,026.25 (or $1,000 plus the Contingent Interest Payment applicable to the final Quarterly Monitoring Period). When added to the Contingent Interest Payments received with respect to the prior Quarterly Monitoring Periods, the total amount paid, for each $1,000 principal amount note, is $1,078.75.

Example 2 — Notes have NOT been redeemed early, the Final Value of the Least Performing Underlying is greater than or equal to its Trigger Value and the closing value of the Least Performing Underlying on at least one day during the final Quarterly Monitoring Period is less than its Interest Barrier.

Date	Closing Value of Least Performing Underlying	Lowest Closing Value of Least Performing Underlying During Quarterly Monitoring Period	Payment (per $1,000 principal amount note)
First Review Date	95.00	90.00	$26.25
Second Review Date	85.00	80.00	$26.25
Third through Thirteenth Review Dates	Various	Less than Interest Barrier	$0
Final Review Date	65.00	60.00	$1,000.00
	Total Payment		$1,052.50 (5.25% return)

PS-4 | Structured Investments Callable Contingent Interest Notes Linked to the Least Performing of the S&P 500^® Index, the Russell 2000^® Index and the iShares^® MSCI EAFE ETF

Because the notes have not been redeemed early, the Final Value of the Least Performing Underlying is greater than or equal to its Trigger Value but the closing value of the Least Performing Underlying on at least one day during the final Quarterly Monitoring Period is less than its Interest Barrier, the payment at maturity, for each $1,000 principal amount note, will be $1,000.00. When added to the Contingent Interest Payments received with respect to the prior Quarterly Monitoring Periods, the total amount paid, for each $1,000 principal amount note, is $1,052.50.

Example 3 — Notes have NOT been redeemed early and the Final Value of the Least Performing Underlying is less than its Trigger Value.

Date	Closing Value of Least Performing Underlying on Review Date	Lowest Closing Value of Least Performing Underlying during Quarterly Monitoring Period	Payment (per $1,000 principal amount note)
First Review Date	60.00	55.00	$0
Second Review Date	55.00	50.00	$0
Third through thirteenth Review Dates	Various	Less than Interest Barrier	$0
Final Review Date	50.00	50.00	$500.00
		Total Payment	$500.00 (-50.00% return)

Because the notes have not been redeemed early, the Final Value of the Least Performing Underlying is less than its Trigger Value (and, therefore, the closing value of the Least Performing Underlying on at least one day during the final Quarterly Monitoring Period is less than its Interest Barrier) and the Least Performing Underlying Return is -50.00%, the payment at maturity will be $500.00 per $1,000 principal amount note, calculated as follows:

$1,000 + [$1,000 × (-50.00%)] = $500.00

The hypothetical returns and hypothetical payments on the notes shown above apply only if you hold the notes for their entire term. These hypotheticals do not reflect the fees or expenses that would be associated with any sale in the secondary market. If these fees and expenses were included, the hypothetical returns and hypothetical payments shown above would likely be lower.

Selected Risk Considerations

An investment in the notes involves significant risks. These risks are explained in more detail in the “Risk Factors” sections of the accompanying product supplement and underlying supplement.

· YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS —

The notes do not guarantee any return of principal. If the notes have not been redeemed early and the Final Value of any Underlying is less than its Trigger Value, you will lose 1% of the principal amount of your notes for every 1% that the Final Value of the Least Performing Underlying is less than its Initial Value. Accordingly, under these circumstances, you will lose more than 45.00% of your principal amount at maturity and could lose all of your principal amount at maturity.

· THE NOTES DO NOT GUARANTEE THE PAYMENT OF INTEREST AND MAY NOT PAY ANY INTEREST AT ALL —

If the notes have not been redeemed early, we will make a Contingent Interest Payment with respect to a Quarterly Monitoring Period only if the closing value of each Underlying on each day during that Quarterly Monitoring Period is greater than or equal to its Interest Barrier. If the closing value of any Underlying on any day during a Quarterly Monitoring Period is less than its Interest Barrier, no Contingent Interest Payment will be made with respect to that Quarterly Monitoring Period. Accordingly, if the closing value of any Underlying on any day during each Quarterly Monitoring Period is less than its Interest Barrier, you will not receive any interest payments over the term of the notes.

· CREDIT RISK OF JPMORGAN CHASE & CO. —

Investors are dependent on JPMorgan Chase & Co.’s ability to pay all amounts due on the notes. Any actual or potential change in our creditworthiness or credit spreads, as determined by the market for taking our credit risk, is likely to adversely affect the value of the notes. If we were to default on our payment obligations, you may not receive any amounts owed to you under the notes and you could lose your entire investment.

PS-5 | Structured Investments Callable Contingent Interest Notes Linked to the Least Performing of the S&P 500^® Index, the Russell 2000^® Index and the iShares^® MSCI EAFE ETF

· THE OPPORTUNITY TO RECEIVE A CONTINGENT INTEREST PAYMENT WITH RESPECT TO ANY QUARTERLY MONITORING PERIOD MAY TERMINATE ON ANY DAY DURING THAT QUARTERLY MONITORING PERIOD —

If the closing value of any Underlying on any day during a Quarterly Monitoring Period is less than its Interest Barrier, no Contingent Interest Payment will be made with respect to that Quarterly Monitoring Period, even if the closing value of each Underlying on each of the other days during that Quarterly Monitoring Period, including the related Review Date, is greater than or equal to its Interest Barrier.

· THE APPRECIATION POTENTIAL OF THE NOTES IS LIMITED TO THE SUM OF ANY CONTINGENT INTEREST PAYMENTS THAT MAY BE PAID OVER THE TERM OF THE NOTES,

regardless of any appreciation in the value of any Underlying, which may be significant. You will not participate in any appreciation in the level of any Underlying.

· POTENTIAL CONFLICTS —

We and our affiliates play a variety of roles in connection with the notes. In performing these duties, our economic interests are potentially adverse to your interests as an investor in the notes. It is possible that hedging or trading activities of ours or our affiliates in connection with the notes could result in substantial returns for us or our affiliates while the value of the notes declines. Please refer to “Risk Factors — Risks Relating to Conflicts of Interest” in the accompanying product supplement.

· WE ARE CURRENTLY ONE OF THE COMPANIES THAT MAKE UP THE S&P 500^® INDEX,

but we will not have any obligation to consider your interests in taking any corporate action that might affect the level of the S&P 500^® Index.

· YOU ARE EXPOSED TO THE RISK OF DECLINE IN THE LEVEL OF EACH UNDERLYING —

Payments on the notes are not linked to a basket composed of the Underlyings and are contingent upon the performance of each individual Underlying. Poor performance by any of the Underlyings over the term of the notes may negatively affect whether you will receive a Contingent Interest Payment on any Interest Payment Date, and your payment at maturity and will not be offset or mitigated by positive performance by the other Underlyings.

· YOUR PAYMENT AT MATURITY MAY BE DETERMINED BY THE LEAST PERFORMING UNDERLYING.

· THE BENEFIT PROVIDED BY THE TRIGGER VALUE MAY TERMINATE ON THE FINAL REVIEW DATE —

If the Final Value of any Underlying is less than its Trigger Value and the notes have not been redeemed early, the benefit provided by the Trigger Value will terminate and you will be fully exposed to any depreciation in the closing value of the Least Performing Underlying.

· THE OPTIONAL EARLY REDEMPTION FEATURE MAY FORCE A POTENTIAL EARLY EXIT —

If your notes are redeemed early, the term of the notes may be reduced to as short as approximately six months and you will not receive any Contingent Interest Payments after the applicable Interest Payment Date. There is no guarantee that you would be able to reinvest the proceeds from an investment in the notes at a comparable return and/or with a comparable interest rate for a similar level of risk. Even in cases where the notes are called before maturity, noteholders are not entitled to any fees and commissions described on the front cover of this pricing supplement.

· YOU WILL NOT RECEIVE DIVIDENDS ON THE FUND OR THE SECURITIES INCLUDED IN OR HELD BY ANY UNDERLYING OR HAVE ANY RIGHTS WITH RESPECT TO THE FUND OR THOSE SECURITIES.

· AN INVESTMENT IN THE NOTES IS SUBJECT TO RISKS ASSOCIATED WITH SMALL CAPITALIZATION STOCKS WITH RESPECT TO THE RUSSELL 2000^® INDEX —

Small capitalization companies may be less able to withstand adverse economic, market, trade and competitive conditions relative to larger companies. Small capitalization companies are less likely to pay dividends on their stocks, and the presence of a dividend payment could be a factor that limits downward stock price pressure under adverse market conditions.

· THERE ARE RISKS ASSOCIATED WITH THE FUND —

The Fund is subject to management risk, which is the risk that the investment strategies of the Fund’s investment adviser, the implementation of which is subject to a number of constraints, may not produce the intended results. These constraints could adversely affect the market price of the shares of the Fund and, consequently, the value of the notes.

PS-6 | Structured Investments Callable Contingent Interest Notes Linked to the Least Performing of the S&P 500^® Index, the Russell 2000^® Index and the iShares^® MSCI EAFE ETF

· DIFFERENCES BETWEEN THE FUND AND THE UNDERLYING INDEX —

The Fund does not fully replicate its Underlying Index (as defined under “The Underlyings” below) and may hold securities not included in its Underlying Index. In addition, the performance of the Fund will reflect additional transaction costs and fees that are not included in the calculation of its Underlying Index. Furthermore, because the shares of the Fund are traded on a securities exchange and are subject to market supply and investor demand, the market value of one share of the Fund may differ from the net asset value per share of the Fund. All of these factors may lead to a lack of correlation between the Fund and its Underlying Index.

· NON-U.S. SECURITIES RISK WITH RESPECT TO THE FUND —

The equity securities held by the Fund have been issued by non-U.S. companies. Investments in securities linked to the value of such non-U.S. equity securities involve risks associated with the securities markets in the home countries of the issuers of those non-U.S. equity securities. Also, there is generally less publicly available information about companies in some of these jurisdictions than there is about U.S. companies that are subject to the reporting requirements of the SEC.

· THE NOTES ARE SUBJECT TO CURRENCY EXCHANGE RISK WITH RESPECT TO THE FUND —

Because the prices of the equity securities held by the Fund are converted into U.S. dollars for purposes of calculating the net asset value of the Fund, holders of the notes will be exposed to currency exchange rate risk with respect to each of the currencies in which the equity securities held by the Fund trade. Your net exposure will depend on the extent to which those currencies strengthen or weaken against the U.S. dollar and the relative weight of equity securities held by the Fund denominated in each of those currencies. If, taking into account the relevant weighting, the U.S. dollar strengthens against those currencies, the price of the Fund will be adversely affected and any payment on the notes may be reduced.

· THE ANTI-DILUTION PROTECTION FOR THE FUND IS LIMITED —

The calculation agent will make adjustments to the Share Adjustment Factor for the Fund for certain events affecting the shares of the Fund. However, the calculation agent will not make an adjustment in response to all events that could affect the shares of the Fund. If an event occurs that does not require the calculation agent to make an adjustment, the value of the notes may be materially and adversely affected.

· THE RISK OF THE CLOSING VALUE OF AN UNDERLYING FALLING BELOW ITS INTEREST BARRIER OR TRIGGER VALUE IS GREATER IF THE VALUE OF THAT UNDERLYING IS VOLATILE.

· LACK OF LIQUIDITY —

The notes will not be listed on any securities exchange. Accordingly, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which JPMS is willing to buy the notes. You may not be able to sell your notes. The notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your notes to maturity.

· THE FINAL TERMS AND VALUATION OF THE NOTES WILL BE PROVIDED IN THE PRICING SUPPLEMENT —

You should consider your potential investment in the notes based on the minimums for JPMS’s estimated value and the Contingent Interest Rate.

· JPMS’S ESTIMATED VALUE OF THE NOTES WILL BE LOWER THAN THE ORIGINAL ISSUE PRICE (PRICE TO PUBLIC) OF THE NOTES —

JPMS’s estimated value is only an estimate using several factors. The original issue price of the notes will exceed JPMS’s estimated value because costs associated with selling, structuring and hedging the notes are included in the original issue price of the notes. These costs include the selling commissions, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. See “JPMS’s Estimated Value of the Notes” in this pricing supplement.

· JPMS’S ESTIMATED VALUE DOES NOT REPRESENT FUTURE VALUES OF THE NOTES AND MAY DIFFER FROM OTHERS’ ESTIMATES —

See “JPMS’s Estimated Value of the Notes” in this pricing supplement.

PS-7 | Structured Investments Callable Contingent Interest Notes Linked to the Least Performing of the S&P 500^® Index, the Russell 2000^® Index and the iShares^® MSCI EAFE ETF

· JPMS’S ESTIMATED VALUE IS NOT DETERMINED BY REFERENCE TO CREDIT SPREADS FOR OUR CONVENTIONAL FIXED-RATE DEBT —

The internal funding rate used in the determination of JPMS’s estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. If JPMS were to use the interest rate implied by our conventional fixed-rate credit spreads, we would expect the economic terms of the notes to be more favorable to you. Consequently, our use of an internal funding rate would have an adverse effect on the terms of the notes and any secondary market prices of the notes. See “JPMS’s Estimated Value of the Notes” in this pricing supplement.

· THE VALUE OF THE NOTES AS PUBLISHED BY JPMS (AND WHICH MAY BE REFLECTED ON CUSTOMER ACCOUNT STATEMENTS) MAY BE HIGHER THAN JPMS’S THEN-CURRENT ESTIMATED VALUE OF THE NOTES FOR A LIMITED TIME PERIOD —

We generally expect that some of the costs included in the original issue price of the notes will be partially paid back to you in connection with any repurchases of your notes by JPMS in an amount that will decline to zero over an initial predetermined period. See “Secondary Market Prices of the Notes” in this pricing supplement for additional information relating to this initial period. Accordingly, the estimated value of your notes during this initial period may be lower than the value of the notes as published by JPMS (and which may be shown on your customer account statements).

· SECONDARY MARKET PRICES OF THE NOTES WILL LIKELY BE LOWER THAN THE ORIGINAL ISSUE PRICE OF THE NOTES —

Any secondary market prices of the notes will likely be lower than the original issue price of the notes because, among other things, secondary market prices take into account our secondary market credit spreads for structured debt issuances and, also, because secondary market prices (a) exclude selling commissions and (b) may exclude projected hedging profits, if any, and estimated hedging costs that are included in the original issue price of the notes. As a result, the price if any, at which JPMS will be willing to buy the notes from you in secondary market transactions, if at all, is likely to be lower than the original issue price. Any sale by you prior to the Maturity Date could result in a substantial loss to you.

· SECONDARY MARKET PRICES OF THE NOTES WILL BE IMPACTED BY MANY ECONOMIC AND MARKET FACTORS —

The secondary market price of the notes during their term will be impacted by a number of economic and market factors, which may either offset or magnify each other, aside from the selling commissions, projected hedging profits, if any, estimated hedging costs and the values of the Underlyings. Additionally, independent pricing vendors and/or third party broker-dealers may publish a price for the notes, which may also be reflected on customer account statements. This price may be different (higher or lower) than the price of the notes, if any, at which JPMS may be willing to purchase your notes in the secondary market. See “Risk Factors — Risks Relating to the Estimated Value of Secondary Market Prices of the Notes — Secondary market prices of the notes will be impacted by many economic and market factors” in the accompanying product supplement.

Tax Treatment

You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 4a-I. In determining our reporting responsibilities we intend to treat (i) the notes for U.S. federal income tax purposes as prepaid forward contracts with associated contingent coupons and (ii) any Contingent Interest Payments as ordinary income, as described in the section entitled “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Notes Treated as Prepaid Forward Contracts with Associated Contingent Coupons” in the accompanying product supplement no. 4a-I. Based on the advice of Davis Polk & Wardwell LLP, our special tax counsel, we believe that this is a reasonable treatment, but that there are other reasonable treatments that the IRS or a court may adopt, in which case the timing and character of any income or loss on the notes could be materially affected. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of

PS-10 | Structured Investments Callable Contingent Interest Notes Linked to the Least Performing of the S&P 500^® Index, the Russell 2000^® Index and the iShares^® MSCI EAFE ETF

related topics, including the character of income or loss with respect to these instruments and the relevance of factors such as the nature of the underlying property to which the instruments are linked. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially affect the tax consequences of an investment in the notes, possibly with retroactive effect. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the notes, including possible alternative treatments and the issues presented by this notice.

Non-U.S. Holders — Tax Considerations. The U.S. federal income tax treatment of Contingent Interest Payments is uncertain, and although we believe it is reasonable to take a position that Contingent Interest Payments are not subject to U.S. withholding tax (at least if an applicable Form W-8 is provided), a withholding agent may nonetheless withhold on these payments (generally at a rate of 30%, subject to the possible reduction of that rate under an applicable income tax treaty), unless income from your notes is effectively connected with your conduct of a trade or business in the United States (and, if an applicable treaty so requires, attributable to a permanent establishment in the United States). If you are not a United States person, you are urged to consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the notes in light of your particular circumstances.

Non-U.S. holders should also note that, notwithstanding anything to the contrary in the accompanying product supplement no. 4a-I, recently promulgated Treasury regulations imposing a withholding tax on certain “dividend equivalents” under certain “equity linked instruments” will not apply to the notes.

FATCA. Withholding under legislation commonly referred to as “FATCA” could apply to payments with respect to the notes that are treated as U.S.-source “fixed or determinable annual or periodical” income (“FDAP Income”) for U.S. federal income tax purposes (such as interest, if the notes are recharacterized, in whole or in part, as debt instruments, or Contingent Interest Payments if they are otherwise treated as FDAP Income). If the notes are recharacterized, in whole or in part, as debt instruments, withholding could also apply to payments of gross proceeds of a taxable disposition, including an early redemption or redemption at maturity. However, under a recent IRS notice, this regime will not apply to payments of gross proceeds (other than any amount treated as FDAP Income) with respect to dispositions occurring before January 1, 2019. You should consult your tax adviser regarding the potential application of FATCA to the notes.

In the event of any withholding on the notes, we will not be required to pay any additional amounts with respect to amounts so withheld.

JPMS’s Estimated Value of the Notes

JPMS’s estimated value of the notes set forth on the cover of this pricing supplement is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the notes, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the notes. JPMS’s estimated value does not represent a minimum price at which JPMS would be willing to buy your notes in any secondary market (if any exists) at any time. The internal funding rate used in the determination of JPMS’s estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. For additional information, see “Selected Risk Considerations — JPMS’s Estimated Value Is Not Determined by Reference to Credit Spreads for Our Conventional Fixed-Rate Debt.”

The value of the derivative or derivatives underlying the economic terms of the notes is derived from JPMS’s internal pricing models. These models are dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, dividend rates, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, JPMS’s estimated value of the notes is determined when the terms of the notes are set based on market conditions and other relevant factors and assumptions existing at that time.

JPMS’s estimated value does not represent future values of the notes and may differ from others’ estimates. Different pricing models and assumptions could provide valuations for notes that are greater than or less than JPMS’s estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the value of the notes could change significantly based on, among other things, changes in market conditions, our creditworthiness, interest rate movements and other relevant factors, which may impact the price, if any, at which JPMS would be willing to buy notes from you in secondary market transactions.

JPMS’s estimated value of the notes will be lower than the original issue price of the notes because costs associated with selling, structuring and hedging the notes are included in the original issue price of the notes. These costs include the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. A portion of the profits, if any, realized in hedging our obligations under the

PS-11 | Structured Investments Callable Contingent Interest Notes Linked to the Least Performing of the S&P 500^® Index, the Russell 2000^® Index and the iShares^® MSCI EAFE ETF

notes may be allowed to other affiliated or unaffiliated dealers, and we or one or more of our affiliates will retain any remaining hedging profits. See “Selected Risk Considerations — JPMS’s Estimated Value of the Notes Will Be Lower Than the Original Issue Price (Price to Public) of the Notes” in this pricing supplement.

Secondary Market Prices of the Notes

For information about factors that will impact any secondary market prices of the notes, see “Risk Factors — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — Secondary market prices of the notes will be impacted by many economic and market factors” in the accompanying product supplement. In addition, we generally expect that some of the costs included in the original issue price of the notes will be partially paid back to you in connection with any repurchases of your notes by JPMS in an amount that will decline to zero over an initial predetermined period. These costs can include projected hedging profits, if any, and, in some circumstances, estimated hedging costs and our secondary market credit spreads for structured debt issuances. This initial predetermined time period is intended to be the shorter of six months and one-half of the stated term of the notes. The length of any such initial period reflects the structure of the notes, whether our affiliates expect to earn a profit in connection with our hedging activities, the estimated costs of hedging the notes and when these costs are incurred, as determined by JPMS. See “Selected Risk Considerations — The Value of the Notes as Published by JPMS (and Which May Be Reflected on Customer Account Statements) May Be Higher Than JPMS’s Then-Current Estimated Value of the Notes for a Limited Time Period.”

Supplemental Use of Proceeds

The notes are offered to meet investor demand for products that reflect the risk-return profile and market exposure provided by the notes. See “How the Notes Work” and “Hypothetical Payout Examples” in this pricing supplement for an illustration of the risk-return profile of the notes and “The Underlyings” in this pricing supplement for a description of the market exposure provided by the notes.

The original issue price of the notes is equal to JPMS’s estimated value of the notes plus the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, plus (minus) the projected profits (losses) that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes, plus the estimated cost of hedging our obligations under the notes.

Additional Terms Specific to the Notes

You may revoke your offer to purchase the notes at any time prior to the time at which we accept such offer by notifying the applicable agent. We reserve the right to change the terms of, or reject any offer to purchase, the notes prior to their issuance. In the event of any changes to the terms of the notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes, in which case we may reject your offer to purchase.
