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

**We expect that delivery of the notes will be made against payment therefor on or about the settlement date specified in this pricing term sheet, which will be the fifth business day following the date of the pricing of the notes, or “T+5.” Under Rule 15c6‑1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the first business day before delivery will be required, by virtue of the fact that the notes initially will settle in T+5, to specify alternative settlement arrangements to prevent a failed settlement and should consult their own advisors.
