It is expected that delivery of the Notes will be made against payment therefor on or about February 28, 2020, which will be the tenth business day following the date of pricing of the Notes (such settlement cycle being referred to herein as ‘‘T+10’’). Under Rule 15c6-1 pursuant to 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 who wish to trade the Notes on the date of pricing or the next seven succeeding business days will be required, by virtue of the fact that the Notes initially will settle in T+10, 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 the Notes during such period should consult their own advisor.
