* Pursuant to Rule 15c6-1 under 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 Securities in the secondary market prior to the date that is one business day before the settlement date will be required, by virtue of the fact that the Securities will initially settle T+3 (on February 26, 2026) to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Securities who wish to trade Securities prior to the date that is one business day before the settlement date should consult their own advisors.
