\* 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 Series X Bonds 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 Series X Bonds initially will settle T+6 (on June 30, 2026) to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of bonds who wish to trade bonds prior to the date that is one business day before the settlement date should consult their own advisors.

\*\* 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.
