The issuer has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the issuer has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by calling Citigroup Global Markets Inc. at (800) 831-9146, J.P. Morgan Securities LLC at (212) 834-4533 or RBC Capital Markets, LLC at (866) 375-6829.

It is expected that delivery of the notes will be made against payment therefor on or about September 18, 2020, which is the seventh business day following the date hereof (such settlement cycle being referred to as “T+7”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to the second business day immediately preceding the date of delivery of the notes will be required, by virtue of the fact that the notes initially will settle in T+7, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.
