Historical Performance of the Underlying Index – Daily Official Closing Levels 

January 2, 2008 to May 25, 2016

Tax considerations:

There is no direct legal authority as to the proper tax treatment of each Trigger PLUS, and therefore significant aspects of the tax treatment of each Trigger PLUS are uncertain as to both the timing and character of any inclusion in income in respect of each Trigger PLUS. Under one approach, each Trigger PLUS could be treated as a pre-paid executory contract with respect to the underlying index. We intend to treat each Trigger PLUS consistent with this approach. Pursuant to the terms of each Trigger PLUS, you agree to treat each Trigger PLUS under this approach for all U.S. federal income tax purposes. Subject to the limitations described therein, and based on certain factual representations received from us, in the opinion of our special U.S. tax counsel, Morrison & Foerster LLP, it is reasonable to treat each Trigger PLUS as a pre-paid executory contract with respect to the underlying index. Pursuant to this approach, we do not intend to report any income or gain with respect to each Trigger PLUS prior to maturity or an earlier sale or exchange, and we intend to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the Trigger PLUS for more than one year at such time for U.S. federal income tax purposes.

We will not attempt to ascertain whether any of the entities whose stock is included in the underlying index would be treated as a passive foreign investment company (a “PFIC”) or United States real property holding corporation (a “USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the underlying index were so treated, certain adverse U.S. federal income tax consequences might apply to a U.S. holder or non-U.S. holder (both as defined in the accompanying prospectus supplement), as the case may be. You should refer to information filed with the SEC and other authorities by the entities whose stock is included in the underlying index and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the underlying index is or becomes a PFIC or a USRPHC.

In Notice 2008-2, the Internal Revenue Service (“IRS”) and the Treasury Department requested comments as to whether the purchaser of certain securities (which may include the Trigger PLUS) should be required to accrue income during its term under a mark-to-market, accrual or other methodology, whether income and gain on such a security or contract should be ordinary or capital and whether foreign holders should be subject to withholding tax on any deemed income accrual. Accordingly, it is possible that regulations or other guidance could provide that a U.S. holder of a Trigger PLUS is required to accrue income in respect of the Trigger PLUS prior to the receipt of payments under the Trigger PLUS or its earlier sale or exchange. Moreover, it is possible that any such regulations or other guidance could treat all income and gain of a U.S. holder in respect of a Trigger PLUS as ordinary income (including gain on a sale or exchange). Finally, it is possible that a non-U.S. holder of the Trigger PLUS could be subject to U.S. withholding tax in respect of a Trigger PLUS. It is unclear whether any regulations or other guidance would apply to the Trigger PLUS (possibly on a retroactive basis). Prospective investors are urged to consult with their tax advisors regarding Notice 2008-2 and the possible effect to them of the issuance of regulations or other guidance that affects the U.S. federal income tax treatment of the Trigger PLUS.

Under current law, while the matter is not entirely clear, individual non-U.S. holders, and entities whose property is potentially includible in those individuals’ gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, the Trigger PLUS is likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their tax advisors regarding the U.S. federal estate tax consequences of investing in the Trigger PLUS.

Recently finalized Treasury Regulations provide that withholding on “dividend equivalent” payments (as discussed in the accompanying prospectus supplement), if any, will not apply to a Trigger PLUS issued before January 1, 2017. Additionally, the IRS has announced that withholding under the Foreign Account Tax Compliance Act (as discussed in the accompanying prospectus supplement) on payments of gross proceeds from a sale, exchange, redemption or other disposition of the Trigger PLUS will only apply to dispositions after December 31, 2018.

For a further discussion of U.S. federal income tax consequences related to each Trigger PLUS, see the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc., an affiliate of HSBC, will purchase the Trigger PLUS from HSBC for distribution to Morgan Stanley Wealth Management. HSBC

Securities (USA) Inc. will act as agent for the Trigger PLUS, will receive a fee of $0.35 per $10 stated principal amount and will pay Morgan Stanley Wealth Management a fixed sales commission of $0.30 for each Trigger PLUS they sell. Of the amount per $10 stated principal amount received by HSBC Securities (USA) Inc., acting as agent for HSBC, HSBC Securities (USA) Inc. will pay Morgan Stanley Wealth Management a structuring fee of $0.05 for each Trigger PLUS.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions after the initial sale of the Trigger PLUS, but is under no obligation to do so and may discontinue any market-making activities at any time without notice.

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-59 in the prospectus supplement.

If the Trigger PLUS have become immediately due and payable following an event of default (as defined in the accompanying prospectus) with respect to the Trigger PLUS, the calculation agent will determine the accelerated payment at maturity due and payable in the same general manner as described in “payment at maturity” in this free writing prospectus. In such a case, the third scheduled trading day for the underlying index immediately preceding the date of acceleration will be used as the valuation date for purposes of determining the accelerated final level. If a market disruption event exists on that scheduled trading day, then the accelerated valuation date will be postponed for up to five scheduled trading days (in the same general manner used for postponing the originally scheduled valuation date). The accelerated maturity date will be the third business day following such accelerated postponed valuation date.
