If, on any determination period-end date (other than the final determination date), beginning November 20, 2024, the closing level of each underlier is greater than or equal to its initial underlier value, the securities will be automatically redeemed for an early redemption payment on the contingent payment date immediately following that determination period-end date.
Early redemption payment:	An amount per security equal to (i) the stated principal amount plus (ii) any contingent quarterly payment otherwise due
Coupon barrier event:	A coupon barrier event will occur with respect to a determination period if the closing level of any underlier is less than its downside threshold level on any scheduled trading day for that underlier during that determination period. Notwithstanding the foregoing, if a market disruption event occurs with respect to an underlier on any scheduled trading day for that underlier during a determination period (other than a determination period end date), the closing level of that underlier on that day will be disregarded for purposes of determining whether a coupon barrier event has occurred with respect to that determination period.
Contingent quarterly payment:	· If a coupon barrier event has not occurred during a determination period, we will pay a contingent quarterly payment of at least $20.25 (at least 2.025% of the stated principal amount) per security on the related contingent payment date with respect to that determination period. · If a coupon barrier event has occurred during a determination period, no contingent quarterly payment will be made with respect to that determination period.
Payment at maturity:	If the securities are not automatically redeemed prior to maturity, you will receive on the maturity date a cash payment per security determined as follows: · If the final underlier value of each underlier is greater than or equal to its downside threshold level: (i) stated principal amount plus (ii) any contingent quarterly payment otherwise due · If the final underlier value of any underlier is less than its downside threshold level: stated principal amount × underlier performance factor of the worst performing underlier Under these circumstances, the payment at maturity will be less than the stated principal amount of $1,000 and will represent a loss of more than 35%, and possibly all, of an investor’s initial investment. Investors may lose their entire initial investment in the securities.

Risk Factors

An investment in the securities involves significant risks. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the securities. Some of the risks that apply to an investment in the securities are summarized below, but we urge you to read the more detailed explanation of risks relating to the securities generally in the “Risk Factors” sections in the accompanying pricing supplement and the prospectus supplement. You should not purchase the securities unless you understand and can bear the risks of investing in the securities.

Risks Relating to the Securities Generally

· The securities do not guarantee the return of any principal.

· You will not receive any contingent quarterly payment for any quarterly determination period if a coupon barrier event occurs on any scheduled trading day during that determination period with respect to any underlier.

· You will not participate in any appreciation in the value of any underlier.

· You are exposed to the market risk of each underlier, with respect to both the contingent quarterly payments, if any, and the payment at maturity, if any.

· Because the securities are linked to the performance of the worst performing underlier, you are exposed to greater risks of no contingent quarterly payments and sustaining a significant loss on your investment than if the securities were linked to just one underlier.

· The securities are subject to early redemption risk.

· Any payment on the securities will be determined based on the closing levels of the underliers on the dates specified.

· Contingent repayment of principal applies only at maturity or upon any automatic early redemption.

· The securities are subject to volatility risk.

· Investing in the securities is not equivalent to investing in any or all underliers or the securities composing the underliers.

· Significant aspects of the tax treatment of the securities are uncertain.

Risks Relating to the Issuer

· Any payments on the securities are subject to issuer credit risk.

· You may lose some or all of your investment if any U.K. Bail-in Power is exercised by the relevant U.K. resolution authority.

Risks Relating to the Underliers

· Adjustments to the underliers could adversely affect the value of the securities.

· Governmental legislative or regulatory actions, such as sanctions, could adversely affect your investment in the securities.

· The securities are subject to small-capitalization companies risk with respect to the RTY Index.

· There are risks associated with investments in securities linked to the value of non-U.S. equity securities in non-U.S. securities markets with respect to the NKY Index.

· The securities do not provide direct exposure to fluctuations in exchange rates between the U.S. dollar and the yen with respect to the NKY Index.

Risks Relating to Conflicts of Interest

· Hedging and trading activity by the issuer and its affiliates could potentially adversely affect the value of the securities.

· We and our affiliates, and any dealer participating in the distribution of the securities, may engage in various activities or make determinations that could materially affect your securities in various ways and create conflicts of interest.

Risks Relating to the Estimated Value of the Securities and the Secondary Market

· The securities will not be listed on any securities exchange, and secondary trading may be limited.

· The market price of the securities will be influenced by many unpredictable factors.

· The estimated value of your securities is expected to be lower than the initial issue price of your securities.

· The estimated value of your securities might be lower if such estimated value were based on the levels at which our debt securities trade in the secondary market.

· The estimated value of the securities is based on our internal pricing models, which may prove to be inaccurate and may be different from the pricing models of other financial institutions.

· The estimated value of your securities is not a prediction of the prices at which you may sell your securities in the secondary market, if any, and such secondary market prices, if any, will likely be lower than the initial issue price of your securities and may be lower than the estimated value of your securities.

· The temporary price at which we may initially buy the securities in the secondary market and the value we may initially use for customer account statements, if we provide any customer account statements at all, may not be indicative of future prices of your securities.
