(1) | Canada Yield Price: a price calculated at the time of redemption to provide a yield to maturity equal to the yield of a Government of Canada bond of appropriate maturity plus a pre-determined spread.
(2) | Carrying values of fixed-rate subordinated indebtedness notes reflect the impact of interest rate hedges in an effective hedge relationship.
(3) | Not redeemable prior to maturity date.
(4) | Debentures are also subject to a non-viability contingent capital (NVCC) provision, necessary for the Debentures to qualify as Tier 2 regulatory capital under Basel III. As such, the Debentures are automatically converted into common shares upon the occurrence of a Trigger Event as described in the capital adequacy guidelines. In such an event, the Debentures are convertible into a number of common shares, determined by dividing 150% of the par value plus accrued and unpaid interest by the average common share price (as defined in the relevant prospectus supplements) subject to a minimum price of $2.50 per share (subject to adjustment in certain events as defined in the relevant prospectus supplements).
(5) | On July 21, 2025, we redeemed all $ 1.0 billion of our 2.01% Debentures due July 21, 2030. In accordance with their terms, the Debentures were redeemed at 100% of their principal amount, together with accrued and unpaid interest thereon.
