It is expected that delivery of the notes will be made, against payment for the notes, on or about November 15, 2018, which will be the fifth business day following the pricing of the notes. Under Rule 15c6-1 of 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 of the notes who wish to trade the notes on the date of pricing or the next two succeeding business days will be required, because the notes initially will settle within five business days (T+5), 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 notes prior to the date of delivery should consult their own legal advisors.
