* 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 depositary shares will be made against payment therefor on or about March 20, 2018, which will be the third business day following the date hereof (such settlement being referred to as “T+3” ). Under Rule 15c6-1 of the Securities and Exchange Act of 1934, 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 who wish to trade the depositary shares prior to the delivery of the depositary shares hereunder will be required, by virtue of the fact that the depositary shares initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the depositary shares who wish to trade the depositary shares prior to their date of delivery hereunder should consult their advisors.
