We expect that the delivery of the notes will be made against payment on March 14, 2025, which is the third business day following the date of this Final Term Sheet (this settlement cycle being referred to as “T+3”). 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 the trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to their date of delivery may be required, by virtue of the fact that the notes initially will settle in T+3, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.
