It is expected that delivery of the notes will be made, against payment of the notes, on or about July 16, 2019, which will be the third business day in the United States following the date of pricing of the notes. Under Rule 15c6-1 of the Exchange Act, purchases or sales of securities in the secondary market generally are required to settle within two business days (this settlement cycle being referred to as “T+2”), unless the parties to any such transaction expressly agree otherwise. Accordingly, purchasers of the notes who wish to trade the notes on the date hereof will be required, because the notes will settle within three business days (T+3) in the United States, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade on the date hereof should consult their own legal advisors.
