Goodwill and Intangible Assets | Note 10: Goodwill and Intangible Assets Goodwill When we complete an acquisition, we allocate the purchase price to the assets acquired, including identifiable intangible assets, and the liabilities assumed. Any portion of the consideration transferred in excess of the fair value of those net assets is considered to be goodwill. Goodwill is not amortized and is instead tested for impairment annually. In performing the impairment test, we utilize fair value less costs to sell for each CGU based on discounted cash flow projections. Cash flows were projected for the first 10 years based on actual operating results, expected future business performance and past experience. Beyond 10 years, cash flows were assumed to grow at perpetual annual rates of up to 1.5% (2.0% in 2024). The discount rates we applied in determining the recoverable amounts in 2025 ranged from 9.3% to 11.6% (9.8% to 10.8% in 2024) and were based on our estimate of the cost of capital for each CGU. The cost of capital for each CGU was estimated using the Capital Asset Pricing Model, based on the historical betas of publicly traded peer companies that are comparable to the CGU. We use significant judgment in determin in g inputs to the discounted cash flow model, which is most sensitive to changes in future cash flows, discount rates and terminal growth rates applied to cash flows beyond the forecast period. The fair value measurement for the cash flow model is categorized as Level 3 as the inputs are not observable in the market. The key assumptions described above may change as market and economic conditions change. However, we estimate that reasonably possible changes in these assumptions are not expected to cause the recoverable amounts of our CGUs to decline below their carrying amounts. A continuity of our goodwill by group of CGUs for the years ended October 31, 2025 and 2024 is as follows:

Certain comparative figures have been reclassified to conform with the current year’s presentation. Intangible Assets Intangible assets related to our acquisitions are initially recorded at fair value at the acquisition date and subsequently at cost less accumulated amortization. Software is recorded at cost less accumulated amortization. Amortization expense is recorded in amortization of intangible assets in our Consolidated Statement of Income. The total cost and associated accumulated amortization of our intangible assets are set out below:

Intangible assets are amortized to income over the period during which we believe the assets will benefit us, on either a straight-line or an accelerated basis, over a period not to exceed 15 years. We have $179 million as at October 31, 2025 ($228 million as at October 31, 2024) of intangible assets with indefinite lives that relate primarily to card processing contracts. The useful lives of intangible assets are reviewed annually for any changes in circumstances. We test definite-life intangible assets for impairment when events or changes in circumstances indicate that their carrying value may not be recoverable. Indefinite-life intangible assets are tested annually for impairment. If any intangible assets are determined to be impaired, we write them down to their recoverable amount, which is the higher of value in use and fair value less costs to sell.
