The Bank has filed a registration statement (File No. 333-201259) (including a short form base shelf prospectus dated December 30, 2014) and a preliminary prospectus supplement dated August 29, 2016 (including the base shelf prospectus, the Prospectus) with the U.S. Securities and Exchange Commission (the SEC) for the offering to which this communication relates. Before you invest, you should read the Prospectus and the documents incorporated therein by reference that the Bank has filed with the SEC for more complete information about the Bank and this offering.

You may obtain these documents for free by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, the Bank or any underwriter participating in the offering will arrange to send you the Prospectus and any document incorporated therein by reference if you request such documents by calling Barclays Capital Inc. toll-free at (888) 603-5847, CIBC World Markets Corp. toll-free at (800) 282-0822, Citigroup Global Markets Inc. toll-free at (800) 831-9146, J.P. Morgan Securities LLC collect at (212) 834-4533 or Wells Fargo Securities, LLC toll-free at (800) 645-3751.

We expect that delivery of the Notes will be made against payment therefor on or about September 6, 2016, which is five business days following the date of pricing of the Notes (this settlement cycle being referred to as “T+5”). Under Rule 15c6-1 of the U.S. Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade their Notes on the date of pricing or the next succeeding business day will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Notes who wish to trade their Notes on the date of pricing or the next succeeding business day should consult their own advisor.
