Designated accounting hedges |
Note 13 |  | Designated accounting hedges
Hedge accounting We apply hedge accounting as part of managing the market risk of certain non-trading portfolios arising from changes due to interest rates, foreign exchange rates, and equity market prices. See the shaded sections in “Non-trading activities” in the MD&A for further information on our risk management strategy for these risks. See Note 12 for further information on the derivatives used by CIBC. Interest rate risk The majority of our derivative contracts used to hedge certain exposures to benchmark interest rate risk are interest rate swaps. For fair value hedges, we convert our fixed interest rate exposures from the hedged financial instruments to floating interest rate exposures. For cash flow hedges, we convert certain exposures to cash flow variability from our variable rate instruments to fixed interest rate exposures. Foreign currency risk For our fair value hedges, we mainly use various combinations of cross-currency interest rate swaps and interest rate swaps to hedge our exposures to foreign currency risk together with interest rate risk, converting our fixed foreign currency rate exposures to floating functional currency rate exposures. For our cash flow hedges, the majority of our derivative contracts are used to hedge our exposures to cash flow variability arising from fluctuations in foreign exchange rates, and mainly consist of cross-currency interest rate swaps. For NIFO hedges, we use a combination of foreign denominated deposit liabilities and foreign exchange forwards to manage our foreign currency exposure of our NIFOs with a functional currency other than the Canadian dollar. Equity price risk We use cash-settled TRS in designated cash flow hedge relationships to hedge changes in CIBC’s share price in respect of certain cash-settled share-based compensation awards. Note 16 provides details on our cash-settled share-based compensation plans. For the hedge relationships described above, hedge effectiveness is assessed at the inception of the hedge relationship and on an ongoing basis, primarily using the dollar offset method. The sources of hedge ineffectiveness are mainly attributed to the following:
• |  | Utilization of hedging instruments that have a non-zero fair value at the inception of the hedge relationship;
• |  | Differences in fixed rates, when contractual coupons of the fixed rate hedged items are designated;
• |  | Differences in the discounting factors between the hedged item and the hedging instruments arising from different rate reset frequencies and timing of cash flows; and
• |  | Differences in the discount curves to determine the basis adjustments of the hedged items and the fair value of the hedging derivatives, including from the application of CVA to the valuation of derivatives when they are applicable.

(1) | For some hedge relationships, we apply a combination of derivatives to hedge the underlying exposures; therefore, the notional amounts of the derivatives generally exceed the carrying amount of the hedged items.
(2) | Notional amount represents the principal amount of deposits as at October 31, 2025 and October 31, 2024.
