** We expect that delivery of the notes will be made against payment therefor on or about October 1, 2020, which will be the sixth business day following the date of the pricing of the notes (such settlement cycle being referred to as “T+6”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally settle in two business days, and purchasers who wish to trade notes on the date of pricing or any subsequent date that is prior to the second trading day preceding the date on which we deliver the notes may be required, by virtue of the fact that the notes initially settle in T+6, to specify alternate settlement arrangements to prevent a failed settlement. Purchasers of the notes who wish to trade the notes on such dates should consult their advisers.
