We expect to deliver the Notes against payment for the Notes on or about June 24, 2024, which will be the fourth business day following the date of the pricing of the Notes. Under 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 a trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes on the date of pricing or the next two succeeding business days will be required, by virtue of the fact that the Notes initially will settle in T+4, to specify alternative settlement arrangements to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes on the date of pricing or the next two succeeding business days should consult their own advisors.
