Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days after the date the securities are priced, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes on the date of pricing or on any of the next three succeeding business days will be required, by virtue of the fact that the Notes will settle in T+7, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement; such purchasers should also consult their own advisers in this regard. As of the date of this Pricing Supplement, the aggregate principal amount (or its equivalent in other currencies) of Debt Securities (as defined in the Prospectus) which have been sold (including the Notes to which this Pricing Supplement relates) is $1,006,000,000. 2
