The Notes pay a fixed rate until an 2032 initial reset date and thereafter reset every five years to a rate tied to the U.S. Treasury rate plus a fixed spread. Initially, the Corresponding Trust Assets will consist of Preferred Shares with a face amount of US$1,000 per share. Upon certain Recourse Events, including a Trigger Event, holders’ sole remedy is delivery of their proportionate share of the Corresponding Trust Assets, which may convert into Common Shares under NVCC conversion rules. The Notes and Preferred Shares are not intended to be listed.
