“Applicable Premium” means, with respect to any Note on any date of redemption, the greater of (a) 1.0% of the principal amount of the Note; and (b) the excess, if any, as determined by the Issuer, of (1) the present value at such redemption date of (x) the redemption price of the Note at September 15, 2025 (such redemption price being set forth in the table above), plus (y) all required interest payments due on the Note through September 15, 2025 (excluding accrued but unpaid interest to the date of redemption), discounted to the date of redemption on a semi-annual basis using a discount rate equal to the Treasury Rate as of such date of redemption plus 50 basis points; over (2) the principal amount of the Note.

“Treasury Rate” means, as of any redemption date, the yield to maturity as of such redemption date of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two business days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the redemption date to September 15, 2025; provided, however, that if the period from the redemption date to September 15, 2025 of such Notes is less than one year, the weekly average yield on actively traded United States Treasury securities adjusted to a constant maturity of one year will be used.

It is expected that delivery of the notes will be made against payment therefor on or about December 17, 2020, which is the seventh business day following the date hereof (such settlement cycle being referred to as “T+7”). Pursuant to Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are 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 more than two business days prior to the settlement date will be required, by virtue of the fact that the depositary shares initially will settle in T+7, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the depositary shares who wish to trade such depositary shares more than two business days prior to the settlement date should consult their own advisors.
