Registration Statement No. 333-202524

Dated October 12, 2016

Filed Pursuant to Rule 433

If, on any of the determination dates, beginning with the fourth determination date, the determination closing level of each underlying index is greater than or equal to its initial index level, the securities will be automatically redeemed for an early redemption payment on the 3rd business day following the related determination date. No further payments will be made on the securities once they have been redeemed.

The securities will not be redeemed if the determination closing level of any underlying index on a determination date is below its initial index level.

·     If, on any determination date, the determination closing level or the final index level, as applicable, of each underlying index is greater than or equal to its coupon barrier level, we will pay a contingent quarterly payment at an annual rate of at least 6.80% of the stated principal amount per security (corresponding to $17.00 (or 1.70%) per quarter per security, rounded to two decimal places) on the related contingent payment date. The actual contingent quarterly payment will be determined on the pricing date.

·     If, on any determination date, the determination closing level or the final index level, as applicable, of any underlying index is less than its coupon barrier level, no contingent quarterly payment will be made with respect to that determination date.

It is possible that one or more underlying indices will remain below their respective coupon barrier levels for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent quarterly payments during the term of the securities.

If the securities have become immediately due and payable following an event of default (as defined in the accompanying prospectus) with respect to the securities, the calculation agent will determine the accelerated payment due and payable at maturity in the same general manner as described in “Payment at maturity” in this free writing prospectus except that the accelerated contingent quarterly payment will be calculated on the basis of a 360-day year consisting of twelve 30-day months. In that case, the scheduled trading day preceding the date of acceleration will be used as the final determination date for purposes of determining the final index level of each underlying index. If a market disruption event exists with respect to an underlying index on that scheduled trading day, then the accelerated final determination date for the applicable underlying index will be postponed for up to 5 scheduled trading days (in the same manner used for postponing the originally scheduled final determination date). The accelerated maturity date will then be the 3rd business day following the postponed accelerated final determination date.

If the securities have become immediately due and payable following an event of default, you will not be entitled to any additional payments with respect to the securities. For more information, see “Description of Debt Securities—Senior Debt Securities—Events of Default” in the prospectus.

Prospective investors should note that the discussion under the section called “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement does not apply to the securities issued under this document and is superseded by the following discussion.

The following summary is a general discussion of the material U.S. federal tax consequences of ownership and disposition of the securities. This discussion applies only to initial investors in the securities who:

·     purchase the securities at their “issue price”; and

·     hold the securities as capital assets, within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”).

This discussion does not describe all of the tax consequences that may be relevant to a holder in light of the holder’s particular circumstances or to holders subject to special rules, such as:

·     certain financial institutions;

·     insurance companies;

·     certain dealers and traders in securities, commodities or foreign currencies;

·     investors holding the securities as part of a “straddle,” conversion transaction, integrated transaction or constructive sale transaction;

·     U.S. Holders, as defined below, whose functional currency is not the U.S. dollar;

·     partnerships or other entities classified as partnerships for U.S. federal income tax purposes;

·     regulated investment companies;

·     real estate investment trusts;

·     tax-exempt entities, including an “individual retirement account” or “Roth IRA”, as defined in Section 408 or 408A of the Code, respectively; or

·     persons subject to the alternative minimum tax.

As the law applicable to the U.S. federal income taxation of instruments such as the securities is technical and complex, the discussion below necessarily represents only a general summary. Moreover, the effect of any applicable state, local or non-U.S. tax laws is not discussed.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed U.S. Treasury Department regulations, all as of the date hereof, changes to

any of which subsequent to the date of this document may affect the tax consequences described herein. Persons considering the purchase of the securities should consult their tax advisors with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

General

There is no direct legal authority as to the proper tax treatment of the securities, and therefore significant aspects of the tax treatment of the securities are uncertain as to both the timing and character of any inclusion in income in respect of the securities. Under one approach, a security could be treated as a single financial contract that provides for a contingent quarterly payment. Pursuant to the terms of the securities, you agree to treat a security for U.S. federal income tax purposes as a single financial contract that provides for a contingent quarterly payment that will be treated as ordinary income to you at the time received or accrued in accordance with your regular method of tax accounting. Subject to the limitations described herein, 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 a security as a single financial contract that provides for a contingent quarterly payment.

Due to the absence of statutory, judicial or administrative authorities that directly address the treatment of the securities or instruments that are similar to the securities for U.S. federal income tax purposes, no assurance can be given that the IRS or the courts will agree with the tax treatment described herein. Accordingly, you should consult your tax advisor regarding all aspects of the U.S. federal tax consequences of an investment in the securities (including possible alternative treatments of the securities) and with respect to any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction. Unless otherwise stated, the following discussion is based on the treatment of each security as described in the previous paragraph.

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

Tax Consequences to U.S. Holders

This section applies to you only if you are a U.S. Holder. As used herein, the term “U.S. Holder” means a beneficial owner of a security that is, for U.S. federal income tax purposes:

·     an individual who is a citizen or resident of the United States, for U.S. federal income tax purposes;

·     a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any political subdivision thereof; or

·     an estate or trust, the income of which is subject to U.S. federal income taxation regardless of its source.

The term “U.S. Holder” also includes certain former citizens and residents of the United States.

Tax Treatment of the Securities

Assuming the treatment of the securities as set forth above is respected, the following U.S. federal income tax consequences should result.

Tax Basis. A U.S. Holder’s tax basis in the securities should equal the amount paid by the U.S. Holder to acquire the securities.

Tax Treatment of Contingent Quarterly Payment. Any contingent quarterly payment on the securities should be taxable as ordinary income to a U.S. Holder at the time received or accrued in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes.

Sale, Exchange, Early Redemption or Settlement of the Securities. Upon a sale, exchange, early redemption or settlement of the securities at maturity, a U.S. Holder should recognize capital gain or

loss equal to the difference between the amount realized (other than with respect to cash attributable to the contingent quarterly payment, which should be treated as discussed above) on the sale, exchange, early redemption or settlement and the U.S. Holder’s tax basis in the securities sold, exchanged, redeemed or settled. Any such gain or loss recognized should be long-term capital gain or loss if the U.S. Holder has held the securities for more than one year at the time of the sale, exchange, early redemption or settlement, and should be short-term capital gain or loss otherwise. The deductibility of capital losses is subject to limitations.

Possible Alternative Tax Treatments of an Investment in the Securities

Due to the absence of authorities that directly address the proper tax treatment of the securities, no assurance can be given that the IRS will accept, or that a court will uphold, the tax treatment described above. In particular, the IRS could seek to treat a security as a single debt instrument. Such a debt instrument would be subject to the special tax rules governing contingent payment debt instruments. If the securities are so treated, a U.S. Holder would generally be required to accrue interest income over the term of the securities based upon the yield at which we would issue a non-contingent fixed-rate debt instrument with other terms and conditions similar to the securities. In addition, any gain a U.S. Holder might recognize upon the sale, exchange, early redemption or settlement of the securities would be ordinary income and any loss recognized by a U.S. Holder would be ordinary loss to the extent of interest that same holder included in income in the current or previous taxable years in respect of the securities, and thereafter, would be capital loss. Because of the absence of authority regarding the appropriate tax characterization of the securities, it is also possible that the IRS could seek to characterize the securities in a manner that results in other tax consequences that are different from those described above. For example, the IRS could assert that any gain or loss that a U.S. Holder may recognize upon the sale, exchange, early redemption or maturity of the securities should be treated as ordinary gain or loss.

Other alternative federal income tax treatments of the securities are also possible, which if applied could also affect the timing and character of the income or loss with respect to the securities. On December 7, 2007, the U.S. 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. The notice focuses on whether to require holders of “prepaid forward contracts” and similar instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; whether short-term instruments should be subject to any such accrual regime; the relevance of factors such as the exchange–traded status of the instruments and the nature of the underlying property to which the instruments are linked; whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose an interest charge; and appropriate transition rules and effective dates. While it is not clear whether instruments such as the securities would be viewed as similar to the prepaid forward contracts described in the notice, any U.S. Treasury Department regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments and the issues presented by this notice.

Backup Withholding and Information Reporting

Backup withholding may apply in respect of the amounts paid to a U.S. Holder, unless such U.S. Holder provides proof of an applicable exemption or a correct taxpayer identification number, or otherwise complies with applicable requirements of the backup withholding rules. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded, or credited against the U.S. Holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the IRS. In addition, information returns may be filed with the IRS in connection with payments on the securities and the proceeds from a sale, exchange, early redemption or other disposition of the securities, unless the U.S. Holder provides proof of an applicable exemption from the information reporting rules.

Tax Consequences to Non-U.S. Holders

This section applies to you only if you are a Non-U.S. Holder. As used herein, the term “Non-U.S. Holder” means a beneficial owner of a security that is for U.S. federal income tax purposes:

·     an individual who is classified as a nonresident alien;

·     a foreign corporation; or

·     a foreign trust or estate.

The term “Non-U.S. Holder” does not include any of the following holders:

·     a holder who is an individual present in the United States for 183 days or more in the taxable year of disposition and who is not otherwise a resident of the United States for U.S. federal income tax purposes;

·     certain former citizens or residents of the United States; or

·     a holder for whom income or gain in respect of the securities is effectively connected with the conduct of a trade or business in the United States.

Such holders should consult their tax advisors regarding the U.S. federal income tax consequences of an investment in the securities.

Because the U.S. federal income tax treatment (including the applicability of withholding) of contingent quarterly payments on the securities is uncertain, the entire amount of the contingent quarterly payments will be subject to U.S. federal income tax withholding at a 30% rate (or at a lower rate under an applicable income tax treaty). We will not pay any additional amounts in respect of such withholding. In order to claim an exemption from or a reduction in the 30% withholding tax, a Non-U.S. Holder of the securities must comply with certification requirements to establish that it is not a U.S. person and is eligible for a reduction of, or an exemption from, withholding under an applicable tax treaty. If you are a Non-U.S. Holder, you should consult your tax advisors regarding the tax treatment of the securities, including the possibility of obtaining a refund of any withholding tax and the certification requirement described above.

A “dividend equivalent” payment is treated as a dividend from sources within the U.S. and such payments generally would be subject to a 30% (or a lower rate under an applicable treaty) U.S. withholding tax if paid to a Non-U.S. Holder. Under U.S. Treasury Department regulations, certain payments (including deemed payments) that are contingent upon or determined by reference to actual or estimated U.S. source dividends with respect to certain equity-linked instruments, whether explicitly stated or implicitly taken into account in computing one or more of the terms of such instrument, may be treated as dividend equivalents. However, this withholding on “dividend equivalent” payments, if any, will not apply to securities issued before January 1, 2017. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes in addition to the withholding tax described above without being required to pay any additional amounts with respect to amounts so withheld.

U.S. Federal Estate Tax

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 securities are 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 securities.

Backup Withholding and Information Reporting

Information returns may be filed with the IRS in connection with payments on the securities and the proceeds from a sale, exchange, early redemption or other disposition. A Non-U.S. Holder may be subject to backup withholding in respect of amounts paid to the Non-U.S. Holder, unless such Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person for U.S. federal income tax purposes or otherwise establishes an exemption. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act

The Foreign Account Tax Compliance Act imposes a 30% U.S. withholding tax on certain U.S. source payments, including interest (and original issue discount), dividends, other fixed or determinable annual or periodical gain, profits, and income, and on the gross proceeds from a disposition of property of a type which can produce U.S. source interest or dividends (“Withholdable Payments”), if paid to a foreign financial institution (including amounts paid to a foreign financial institution on behalf of a holder), unless such institution enters into an agreement with the U.S. Treasury Department to collect and provide to the U.S. Treasury Department substantial information regarding U.S. account holders, including certain account holders that are foreign entities with U.S. owners, or otherwise establishes an exemption. The legislation also generally imposes a withholding tax of 30% on Withholdable Payments made to a non-financial foreign entity unless such entity provides the withholding agent with a

certification that it does not have any substantial U.S. owners or a certification identifying the direct and indirect substantial U.S. owners of the entity or otherwise establishes an exemption.

The U.S. Treasury Department and the IRS have announced that withholding on payments of gross proceeds from a sale, exchange, redemption or other disposition of the securities will only apply to dispositions after December 31, 2018. Holders are urged to consult with their own tax advisors regarding the possible implications of this legislation on their investment in the securities.
