We expect that delivery of the Depositary Shares will be made against payment for the Depositary Shares on or about the Settlement Date indicated above, which will be the fifth business day following the trade date of August 12, 2021 (this settlement cycle being referred to as “T+5”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally will be required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Depositary Shares on any date prior to the fifth business day preceding the Settlement Date will be required, by virtue of the fact that the shares will initially settle in five business days (T+5), to specify alternative settlement arrangements to prevent a failed settlement and should consult their own investment advisor.
