* Note: A securities rating is not a recommendation to buy, sell or hold securities and is subject to revision or withdrawal at any time.

** We expect delivery of the notes will be made against payment therefor on or about August 11, 2020, which is the fifth business day following the date of pricing of the notes (such settlement being referred to as “T+5”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, 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 trading day prior to the closing of this offering will be required, by virtue of the fact that the notes initially will settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisers.
