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

** 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 (“T+1”), unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on the Trade Date or the following business day will be required, by virtue of the fact that the Notes initially will not settle in T+1, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisor.
