Structured  Investments	$ Buffered Callable Range Accrual Notes linked to the S&P 500® Index due September 29, 2023

General

· Unsecured and unsubordinated obligations of JPMorgan Chase & Co. maturing September 29, 2023, subject to postponement as described below.

· The notes are designed for investors who believe that (i) the Index Level of the S&P 500^® Index will remain at or above the Minimum Index Level of 80% of the Initial Index Level on each Accrual Determination Date and (ii) the Index Level of the S&P 500^® Index will be greater than or equal to the Buffer Level of 80% of the Initial Index Level on the Observation Date.

· The notes are designed for investors who seek periodic interest payments that will accrue at a per annum rate equal to 6.20%, provided that the Closing Level of the S&P 500^® Index on each Accrual Determination Date during such Interest Period is greater than or equal to the Minimum Index Level (80% of the Index Level of the S&P 500^® Index on the Pricing Date).

· If the level of the S&P 500^® Index is less than the Minimum Index Level for an entire Interest Period, the Interest Rate for such Interest Period will be equal to zero. In addition, investors should be willing to assume the risk that if the Ending Index Level is less than the Buffer Level, they will lose some and may lose 80% of their principal at maturity. Any payment on the notes is subject to the credit risk of JPMorgan Chase & Co.

· Subject to satisfaction of the Accrual Provision, interest on the notes will be calculated based on the Interest Factor, which will be equal to 6.20%. In no event will the Interest Rate be greater than 6.20% per annum or less than the Minimum Interest Rate of 0% per annum.

· At our option, we may call your notes prior to their scheduled Maturity Date on one of the Redemption Dates set forth below. For more information, see “Key Terms” and “Selected Risk Considerations” in this pricing supplement.

· The terms of the notes as set forth below, to the extent they differ or conflict with those set forth in the accompanying product supplement no. 1a-1, will supersede the terms set forth in product supplement no. 1a-1. In particular, whether the Accrual Provision is satisfied will depend on the Index Level on the applicable Accrual Determination Date (rather than on the Index Level on an Equity Index Determination Date as described in product supplement no. 1a-1), as set forth below. Please refer to “Additional Key Terms — Accrual Provision,” “Additional Key Terms — Accrual Determination Date,” “Key Terms — Redemption Feature” and “Selected Purchase Considerations — Periodic Interest Payments” in this pricing supplement for more information.

· Notes may be purchased in minimum denominations of $1,000 and in integral multiples of $1,000 thereafter.

· The notes are expected to price on or about March 28, 2016 and are expected to settle on or about March 31, 2016.

Key Terms

Payment at Maturity:	If the Ending Index Level is greater than or equal to the Buffer Level, you will receive the principal amount of your notes at maturity. If the Ending Index Level is less than the Buffer Level, you will lose 1% of the principal amount of your notes for every 1% that the Ending Index Level is less than the Buffer Level, and your payment at maturity per $1,000 principal amount note will be calculated as follows: $1,000 + ($1,000 × (Index Return + Buffer Amount)) If the Ending Index Level is less than the Buffer Level, you will lose some and may lose up to 80% of your principal at maturity. Regardless of whether the Ending Index Level is greater than, equal to or less than the Buffer Level, at maturity you will also receive any accrued and unpaid interest on your notes.
Initial Index Level:	The Index Level on the Pricing Date
Ending Index Level:	The Index Level on the Observation Date
Index Return:	(Ending Index Level - Initial Index Level) Initial Index Level
Buffer Level:	80.00% of the Initial Index Level

Callable Range Accrual Notes linked to the S&P 500® Index due September 29, 2023

Selected Purchase Considerations

· LIMITED PROTECTION AGAINST LOSS - We will pay you your principal back at maturity if the Ending Index Level is not less than the Buffer Level. If the Ending Index Level is less than the Buffer Level, for every 1% that the Ending Index Level is less than the Buffer Level, you will lose an amount equal to 1% of the principal amount of your notes. If the Ending Index Level is less than the Buffer Level, you will lose some and may lose up to 80% of your principal at maturity.

· RETURN LINKED TO THE S&P 500^® INDEX - The S&P 500^® Index consists of 500 component stocks selected to provide a performance benchmark for the U.S. equity markets. For additional information about the S&P 500^® Index, see the information set forth under “Equity Index Descriptions — The S&P 500^® Index” in the accompanying underlying supplement no. 1a-I.

· PRESERVATION OF CAPITAL UPON EARLY REDEMPTION — Regardless of the performance of the S&P 500^® Index, we will pay you at least the principal amount of your notes upon early redemption. Because the notes are our unsecured and unsubordinated obligations, payment of any amount upon early redemption is subject to our ability to pay our obligations as they become due.

· PERIODIC INTEREST PAYMENTS — The notes offer periodic interest payments on each Interest Payment Date. The notes will pay interest at the applicable variable Interest Rate, which takes into account the Accrual Provision. The interest payments for all Interest Periods will be affected by the official closing level of the S&P 500^® Index as described under “Interest Rate” on the cover of this pricing supplement, but will not reflect the performance of such rates or such Index. In no event will the Interest Rate during any Interest Period be less than the Minimum Interest Rate of 0.00% per annum. The yield on the notes may be less than the overall return you would receive from a conventional debt security that you could purchase today with the same maturity as the notes.

· POTENTIAL EARLY REDEMPTION BY US AT OUR OPTION — At our option, we may redeem the notes, in whole but not in part, on each of the Redemption Dates set forth above, commencing on March 31, 2017, at a price equal to 100% of the principal amount being redeemed plus any accrued and unpaid interest, subject to the Business Day Convention and the Interest Accrual Convention described on the cover of this pricing supplement and in the accompanying product supplement no. 1a-1. Any accrued and unpaid interest on notes redeemed will be paid to the person who is the holder of record of such notes at the close of business on the Business Day immediately preceding the applicable Redemption Date. Even in cases where the notes are called before maturity, noteholders are not entitled to any fees or commissions described on the front cover of this pricing supplement.

· TAX TREATMENT— You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 1a-I. Based on the advice of Sidley Austin LLP, our special tax counsel, and on current market conditions, in determining our reporting responsibilities we intend to treat the notes for U.S. federal income tax purposes as income-bearing pre-paid derivative contracts. By purchasing the notes, you agree (in the absence of an administrative determination or judicial ruling to the contrary) to follow this treatment. However, there are other reasonable treatments that the Internal Revenue Service (the “IRS”) or a court may adopt, in which case the timing and character of any income or loss on the notes could be significantly and adversely affected. In addition, in 2007, the Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. While it is not clear whether the notes would be viewed as similar to the typical prepaid forward contract described in the notice, it is possible that any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect. The notice focuses on a number of issues, the most relevant of which for holders of the notes are the character of income or loss and the degree, if any, to which income realized by Non-U.S. Holders should be subject to withholding tax.

Assuming that the treatment of the notes as income-bearing pre-paid derivative contracts is respected, interest payments that you receive should be included in ordinary income at the time you receive the payments or when the payments accrue, in accordance with your regular method of accounting for U.S. federal income tax purposes.

Under this treatment, any gain or loss recognized upon the sale, exchange or maturity of the notes should be treated as capital gain or loss. Any such capital gain or loss should be treated as long-term capital gain or loss if you held the notes for more than one year.

Non-U.S. Holders should note that because the United States federal income tax treatment (including the applicability of withholding) of the interest payments on the notes is uncertain, and although the Company believes it is reasonable to take a position that the interest payments are not subject to U.S. withholding tax (at least if the applicable IRS Form W-8 is provided), a withholding agent could possibly nonetheless withhold on these payments (generally at a rate of 30%, subject to the possible reduction or elimination 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). In the event of any withholding, we will not be required to pay any additional amounts with respect to amounts so withheld. If you are a Non-U.S. Holder, you are urged to consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the notes in light of your particular circumstances.

JPMorgan Structured Investments —	PS-3
Callable Range Accrual Notes linked to the S&P 500® Index due September 29, 2023

Non-U.S. Holders should also note that final Treasury regulations were released on legislation that imposes a withholding tax of 30% on payments to certain foreign entities unless information reporting and diligence requirements are met, as described in “Material U.S. Federal Income Tax Consequences-Tax Consequences to Non-U.S. Holders” in the accompanying product supplement. Pursuant to the final regulations, such withholding tax will generally apply to obligations that are issued on or after July 1, 2014; therefore, the notes will generally be subject to this withholding tax. The withholding tax described above will not apply to payments of gross proceeds from the sale, exchange or other disposition of the notes made before January 1, 2019.

Both U.S. and Non-U.S. Holders should consult their tax advisors regarding all aspects of the U.S. federal income tax consequences of an investment in the notes, including possible alternative treatments and the issues presented by the 2007 notice. Purchasers who are not initial purchasers of notes at the issue price should also consult their tax advisors with respect to the tax consequences of an investment in the notes, including possible alternative treatments.

Subject to certain assumptions and representations received from us, the discussion in this section entitled “Tax Treatment”, when read in combination with the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement, constitutes the full opinion of Sidley Austin LLP regarding the material U.S. federal income tax treatment of owning and disposing of the notes.

Selected Risk Considerations

An investment in the notes involves significant risks. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 1a-1 dated November 7, 2014 and the accompanying underlying supplement no. 1a-I dated November 7, 2014.

· YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS — The return on the notes at maturity is linked to the performance of the Index and will depend on whether, and the extent to which, the Index Return is positive or negative. Your investment will be exposed to loss if the Ending Index Level is less than the Buffer Level. For every 1% that the Ending Index Level is less than the Buffer Level, you will lose an amount equal to 1% of the principal amount of your notes. Accordingly, if the Ending Index Level is less than the Buffer Level, you will lose some and may lose up to 80% of your principal at maturity.

· THE NOTES ARE NOT ORDINARY DEBT SECURITIES AND ARE SUBJECT TO AN INTEREST ACCRUAL PROVISION; THE INTEREST RATE ON THE NOTES IS VARIABLE AND MAY BE EQUAL TO 0.00% — The terms of the notes differ from those of ordinary debt securities in that the rate of interest you will receive is not fixed, but will vary based on the level of the S&P 500^® Index over the course of each Interest Period. For each Interest Period the maximum interest rate per annum is equal to the Interest Factor set forth above on the cover of this pricing supplement. This is because the variable Interest Rate on the notes, while determined by reference to the official closing level of the S&P 500^® Index as described on the cover of this pricing supplement, does not actually pay an amount based directly on such level. Your return on the notes for any Interest Period will not exceed the Interest Factor, regardless of the appreciation in the S&P 500^® Index, which may be significant. Moreover, each calendar day during an Interest Period for which the Index Level of the S&P 500^® Index is less than the Minimum Index Level (as determined based on the level of the S&P 500^® Index on the applicable Accrual Determination Date) will result in a reduction of the Interest Rate per annum payable for the corresponding Interest Period. For all Interest Periods if the official closing level of S&P 500^® Index is less than the Minimum Index Level for an entire Interest Period, the Interest Rate for such Interest Period will be equal to 0.00% and you will not receive any interest payment for such Interest Period. In that event, you will not be compensated for any loss in value due to inflation and other factors relating to the value of money over time during such period.

· THE NOTES REFERENCE AN EQUITY INDEX — If the Index Level of the S&P 500^® Index is less than the Minimum Index Level on any Accrual Determination Date, the notes will not accrue interest on that day. If the notes do not satisfy the Accrual Provision for each calendar day in an Interest Period, the Interest Rate payable on the notes will be equal to 0.00% per annum for such Interest Period. You should carefully consider the movement, current level and overall trend in equity markets prior to purchasing these notes. Although the notes do not directly reference the level of the S&P 500^® Index, the interest, if any, payable on your notes is contingent upon, and related to, this level.

· THE INTEREST RATE ON THE NOTES IS SUBJECT TO A MAXIMUM INTEREST RATE — The rate of interest payable on the notes is variable; however, it is still subject to a maximum interest rate equal to the Interest Factor. Although the notes are subject to an Accrual Provision, the interest (if any) payable on the notes accrues at a rate based on the Interest Factor set forth above, and therefore the amount of interest payable on the notes remains subject to the maximum interest rate equal to a Interest Factor.

· THE INTEREST RATE ON THE NOTES MAY BE BELOW THE RATE OTHERWISE PAYABLE ON SIMILAR VARIABLE RATE notes ISSUED BY US — The value of the notes will depend on the Interest Rate on the notes, which will be affected by the level of the S&P 500^® Index. If the level of the S&P 500^® Index is less than the Minimum Index Level on any Accrual Determination Date, the Interest Rate on the notes may be less than returns on similar variable rate notes issued by us that are not linked the S&P 500^® Index. We have no control over any fluctuations in the S&P 500^® Index.

JPMorgan Structured Investments —	PS-4
Callable Range Accrual Notes linked to the S&P 500® Index due September 29, 2023

· THE RETURN OF ANY PRINCIPAL COMPONENT OF YOUR PAYMENT AT MATURITY WILL BE DETERMINED BY THE PERFORMANCE OF THE INDEX — If the notes are not called and the Ending Index Level is less than the Buffer Level, you will lose some and may lose up to 80% of your investment in the notes.

· THE METHOD OF DETERMINING WHETHER THE ACCRUAL PROVISION HAS BEEN SATISFIED MAY NOT DIRECTLY CORRELATE TO THE ACTUAL LEVEL OF the S&P 500^® Index — The determination of the Interest Rate per annum payable for any Interest Period will be based on the actual number of days in that Interest Period on which the Accrual Provision is satisfied, as determined on each Accrual Determination Date. However, we will use the same Index Level of the S&P 500^® Index to determine whether the Accrual Provision is satisfied for the period commencing on the sixth Business Day prior to but excluding each applicable Interest Payment Date, which period we refer to as the Exclusion Period. The Index Level used will be the Index Level of the S&P 500^® Index on the first Trading Day immediately preceding the Exclusion Period, regardless of what the actual closing level of the S&P 500^® Index is for the calendar days in that period or whether the Accrual Provision could have otherwise been satisfied if actually tested in the Exclusion Period. As a result, the determination as to whether the Accrual Provision has been satisfied for any Interest Period may not directly correlate to the actual Index Levels of the S&P 500^® Index, which will in turn affect the Interest Rate calculation.

· YOUR RETURN ON THE NOTES IS LIMITED TO THE PRINCIPAL AMOUNT PLUS ACCRUED INTEREST REGARDLESS OF ANY APPRECIATION IN THE VALUE OF THE INDEX — If the notes are not called and the Ending Index Level is greater than or equal to the Buffer Level, for each $1,000 principal amount note, you will receive $1,000 at maturity plus any accrued and unpaid interest, regardless of any appreciation in the value of the Index, which may be significant. In addition, if the notes are called, for each $1,000 principal amount note, you will receive $1,000 plus any accrued and unpaid interest, regardless of the appreciation in the value of the Index, which may be significant. Accordingly, the return on the notes may be significantly less than the return on a direct investment in the Index during the term of the notes.

· LONGER DATED NOTES MAY BE MORE RISKY THAN SHORTER DATED NOTES — By purchasing a note with a longer tenor, you are more exposed to fluctuations in interest rates than if you purchased a note with a shorter tenor. Specifically, you may be negatively affected if certain interest rate scenarios occur or if the Index Level of the S&P 500^® Index is less than the Minimum Index Level for an entire Interest Period. The applicable discount rate, which is the prevailing rate in the market for notes of the same tenor, will likely be higher for notes with longer tenors than if you had purchased a note with a shorter tenor. Therefore, assuming the notes have not been called and that short term rates rise, as described above, the market value of a longer dated note will be lower than the market value of a comparable short term note with similar terms.

· WE MAY CALL YOUR NOTES PRIOR TO THEIR SCHEDULED MATURITY DATE — We may choose to call the notes early or choose not to call the notes early on any Redemption Date in our sole discretion. If the notes are called early, you will receive the principal amount of your notes plus accrued and unpaid interest to, but not including the Redemption Date. The aggregate amount that you will receive through and including the Redemption Date may be less than the aggregate amount that you would have received had the notes not been called early. If we call the notes early, you will not receive interest payments after the applicable Redemption 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 in the event the notes are redeemed prior to the Maturity Date. We may choose to call the notes early, for example, if U.S. interest rates decrease significantly or if volatility of U.S. interest rates decreases significantly.

· NO DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the notes you will not have voting rights, or rights to receive cash dividends or other distributions, or other rights that holders of securities composing the S&P 500^® Index would have.

· REINVESTMENT RISK — If we redeem the notes, the term of the notes may be reduced and you will not receive interest payments after the applicable Redemption 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 in the event the notes are redeemed prior to the Maturity Date.

· VARIABLE RATE NOTES DIFFER FROM FIXED RATE NOTES — The variable Interest Rate for all Interest Periods will be determined by the Accrual Provision set forth on the cover of this pricing supplement, which is contingent upon the Index Level of the S&P 500^® Index and may be less than returns otherwise payable on debt securities issued by us with similar maturities. You should consider, among other things, the overall potential annual percentage rate of interest to maturity of the notes as compared to other investment alternatives.

· MARKET DISRUPTION EVENTS MAY ADVERSELY AFFECT THE RATE AT WHICH THE NOTES ACCRUE INTEREST — The rate at which the notes accrue interest for an Interest Period will be based on the Index Level of the S&P 500^® Index on the applicable Accrual Determination Date. Notwithstanding anything to the contrary herein or in the accompanying product supplement no. 1a-I, if a market disruption event occurs or is continuing on any Accrual Determination Date, the Accrual Provision will be deemed to have not been satisfied on such Accrual Determination Date (including any originally scheduled Accrual Determination Date relating to an Exclusion Period). Because, your notes will not accrue interest unless the Accrual Provision is satisfied, if a market disruption event continues for an extended period of time, the amount of interest that accrues on the notes may be severely limited.

· CREDIT RISK OF JPMORGAN CHASE & CO. — The notes are subject to the credit risk of JPMorgan Chase & Co., and our credit ratings and credit spreads may adversely affect the market value of the notes. 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.

· POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent and as an agent of the offering of the notes, 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, which we refer to as JPMS’s estimated value. In performing these duties, our economic interests and the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the notes. In addition, our business activities, including hedging and trading activities as well as modeling and structuring the economic terms of the notes, could cause our economic interests to be adverse to yours and could adversely affect any payment on the notes and the value of 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 the Notes Generally” in the accompanying product supplement no. 1a-I for additional information about these risks.

We are also currently one of the companies that make up the S&P 500^® Index. We will not have any obligation to consider your interests as a holder of the notes in taking any corporate action that might affect the value of the S&P 500^® Index and the notes.

· 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 —JPMS’s estimated value of the notes is determined by reference to JPMS’s internal pricing models when the terms of the notes are set. This estimated value is based on market conditions and other relevant factors existing at that time and JPMS’s assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors. 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. See “JPMS’s Estimated Value of the Notes” in this pricing supplement.

· 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. 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. 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

JPMorgan Structured Investments —	PS-6
Callable Range Accrual Notes linked to the S&P 500® Index due September 29, 2023

notes. As a result, the price, if any, at which JPMS will be willing to buy 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. See the immediately following risk consideration for information about additional factors that will impact any secondary market prices of the 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. See “Lack of Liquidity” below.

· 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, and estimated hedging costs, including, but not limited to:

· the performance of the Index;

· any actual or potential change in our creditworthiness or credit spreads;

· customary bid-ask spreads for similarly sized trades;

· secondary market credit spreads for structured debt issuances;

· the time to maturity of the notes;

· dividend rates on the equity securities underlying the Index;

· interest and yield rates in the market generally, as well as the volatility of those rates;

· the likelihood, or expectation, that the notes will be redeemed by us, based on prevailing market interest rates or otherwise; and

· a variety of other economic, financial, political, regulatory and judicial events.

Like many long- term notes with short term call dates, secondary prices can drop sharply if the market shifts from assuming a call to assuming the note will be left outstanding indefinitely.

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.

· SECONDARY MARKET PRICES OF THE NOTES ARE SENSITIVE TO BOTH INTEREST RATES AND THE PERFORMANCE OF THE INDEX — If interest rates rise generally, the secondary market prices of the notes will be adversely impacted because of the relatively long term of the notes and the increased probability that that the Interest Rate for the notes will be less than such rates.  Additionally, if the Index Level declines, even if the Index Level has not declined below the Buffer Level, the secondary market prices of the notes will also be adversely impacted because of the increased probability that the Accrual Provision may not be satisfied over the remaining term of the notes and the increased probability that you may lose some or all of your principal at maturity.  If both interest rates rise and the Index Level declines, the secondary market prices of the notes may decline more rapidly than other securities that are only linked to the Index, or if the amount payable at maturity was not linked to the performance of the Index relative to the Buffer Level.

· LACK OF LIQUIDITY — The notes will not be listed on any securities exchange. JPMS intends to offer to purchase the notes in the secondary market but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Because other dealers are not likely to make a secondary market for the notes, 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.

· MARKET FACTORS MAY INFLUENCE WHETHER WE EXERCISE OUR RIGHT TO REDEEM THE NOTES PRIOR TO THEIR SCHEDULED MATURITY — We have the right to redeem the notes prior to the Maturity Date, in whole but not in part, on the specified Redemption Dates. It is more likely that we will redeem the notes prior to the Maturity Date if the Closing Level of the S&P 500^® Index is greater than or equal to the Minimum Index Level on the applicable Accrual Determination Date. If the notes are called prior to the Maturity Date, you may be unable to invest in certificates of deposit with similar risk and yield as the notes. Your ability to realize a higher than market yield on the notes is limited by our right to redeem the notes prior to their scheduled maturity, which may adversely affect the value of the notes in the secondary market, if any.

· The TERMS AND VALUATION OF THE NOTES WILL BE PROVIDED IN THE PRICING SUPPLEMENT— The final terms of the notes will be based on relevant market conditions when the terms of the notes are set and will be provided in the pricing supplement. In particular, JPMS’s estimated value will be provided in the pricing supplement, and the estimated value of the notes may be equal to the low end of the applicable range set forth on the cover of this pricing supplement. Accordingly, you should consider your potential investment in the notes based on the low end of the range for JPMS’s estimated value.

· TAX DISCLOSURE — The information under “Tax Treatment" in this pricing supplement remains subject to confirmation by our tax counsel. We will notify you of any revisions to the information under “Tax Treatment" in a supplement to this pricing supplement on or before the business day immediately preceding the issue date, or if the information cannot be confirmed by our tax counsel, we may terminate this offering of notes.

Hypothetical Examples of Calculation of the Interest Rate on the Notes for an Interest Period

The following examples illustrate how to calculate the Interest Rate on the notes for four hypothetical Interest Periods. The following examples assume that we have not called the notes prior to their scheduled Maturity Date, the Interest Factor is

JPMorgan Structured Investments —	PS-7
Callable Range Accrual Notes linked to the S&P 500® Index due September 29, 2023

6.20% and the actual number of days in the applicable Interest Period is 90. The hypothetical Interest Rates in the following examples are for illustrative purposes only and may not correspond to the actual Interest Rates for any Interest Period applicable to a purchaser of the notes. The numbers appearing in the following examples have been rounded for ease of analysis.

Example 1: The number of Variable Days in the Interest Period is 81, therefore, the Interest Rate per annum for the Interest Period is equal to 5.58% per annum calculated as follows:

6.20% × (81/90) = 5.58% per annum

Example 2: The number of Variable Days in the Interest Period is 90, therefore, the Interest Rate per annum for the Interest Period is equal to 6.20% per annum, calculated as follows:

6.20% × (90 / 90) = 6.20% per annum

Example 3: The number of Variable Days in the Interest Period is 18, therefore, the Interest Rate per annum for the Interest Period is equal to the Minimum Interest Rate of 1.24% per annum, calculated as follows:

6.20% × (18 / 90) = 1.24% per annum

Example 4: For an Interest Period the Accrual Provision is not met on any calendar day during the Interest Period, and therefore, the number of Variable Days is 0. Because the Accrual Provision is not satisfied on any calendar day, the Interest Rate per annum for the Interest Period will be equal to 0.00% per annum.

Hypothetical Examples of Amounts Payable at Maturity

The following examples illustrate how to calculate the payment at maturity. For purposes of the following examples, we have assumed an Initial Index Level of 2,000, a Buffer Level of 1,600 and the Buffer Amount of 20%, and that the notes are not called prior to their scheduled Maturity Date. Each hypothetical payment at maturity set forth below is for illustrative purposes only and may not be the actual payment at maturity applicable to a purchaser of the notes. In addition, the effect of any accrued and unpaid interest has been excluded.

Example 1: The level of the Index increases from the Initial Index Level of 2,000 to an Ending Index Level of 2,500. Because the Ending Index Level of 2,500 is greater than the Initial Index Level of 2,000, the investor receives a payment at maturity of $1,000 per $1,000 principal amount note.

Example 2: The level of the Index decreases from the Initial Index Level of 2,000 to an Ending Index Level of 1,800. Although the Index Return is negative, because the Ending Index Level of 1,800 is not less than the Buffer Level of 1,600, the investor receives a payment at maturity of $1,000 per $1,000 principal amount note.

Example 3: The level of the Index decreases from the Initial Index Level of 2,000 to an Ending Index Level of 900. Because the Index Return is negative and the Ending Index Level of 900 is less than the Buffer Level of 1,600, the investor receives a payment at maturity of $650.00 per $1,000 principal amount note, calculated as follows:

$1,000 + ($1,000 × (-55.00% + 20.00%) = $650.00

Example 4: The level of the Index decreases from the Initial Index Level of 2,000 to an Ending Index Level of 0. Because the Index Return is negative and the Ending Index Level of 0 is less than the Buffer Level of 1,600, the investor receives a payment at maturity of $200.00 per $1,000 principal amount note, calculated as follows:

$1,000 + ($1,000 × (-100% + 20.00%)) = $200.00

The hypothetical payments on the notes shown above apply only if the notes are not called prior to maturity and you hold the notes for their entire term. 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 payments shown above would likely be lower.

What is the S&P 500^® Index?

The S&P 500^® Index consists of 500 component stocks selected to provide a performance benchmark for the U.S. equity markets. For additional information on the S&P 500^® Index, see the information set forth under “Equity Index Descriptions — The S&P 500^® Index” in the accompanying underlying supplement no. 1a-I.

Historical Information

The following graph sets forth the weekly historical performance of the S&P 500^® Index for the period from January 4, 2008 through February 26, 2016. The Index closing level on March 1, 2016 was 1,978.35.

We obtained the Index Levels used to construct the graph below from Bloomberg Financial Markets. We make no representation or warranty as to the accuracy or completeness of the information obtained from Bloomberg Financial Markets. The historical levels of the Index should not be taken as an indication of future performance, and no assurance can be given as to the Index Level on any of the Accrual Determination Dates. We cannot give you assurance that the performance of the Index will result in any positive interest payments or return of principal at maturity.

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, 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. See “Selected Risk Considerations — JPMS’s Estimated Value Does Not Represent Future Values of the Notes and May Differ from Others’ Estimates” in this pricing supplement.

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 realized in hedging our obligations under the 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 “Selected Risk Considerations — Secondary Market Prices of the Notes Will Be Impacted by Many Economic and Market Factors” in this pricing 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 that 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” in this pricing supplement.

Supplemental Use of Proceeds

The net proceeds we receive from the sale of the notes will be used for general corporate purposes and, in part, by us or one or more of our affiliates in connection with hedging our obligations under the notes.

The notes are offered to meet investor demand for products that reflect the risk-return profile and market exposure provided by the notes. See “Selected Purchase Considerations” and “Hypothetical Examples of Calculation of the Interest Rate on the Notes for an Interest Period” in this pricing supplement for a description of the risk-return profile and market exposure payable under 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.

For purposes of the notes offered by this pricing supplement, the first and second paragraph of the section entitled “Use of Proceeds and Hedging” on page PS-34 of the accompanying product supplement no. 1a-I are deemed deleted in their entirety. Please refer instead to the discussion set forth above.
