The Issuer expects to deliver the notes against payment for the notes on or about November 13, 2017, which will be the third business day following the date of the pricing of the notes, or “T+3”. Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of pricing will be required, by virtue of the fact that the notes initially will settle T+3, to specify alternative settlement arrangements at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes on the date of pricing should consult their advisors.
