Goodwill and Intangible Assets, Goodwill, Policy	Goodwill and Intangible Assets Goodwill and indefinite life intangible assets are initially recorded at fair value and not amortized, but are reviewed for impairment at least annually, or more frequently if impairment indicators arise. The first day of the fourth quarter is our annual impairment assessment date for goodwill and indefinite life intangible assets. However, we could be required to evaluate the recoverability of goodwill and indefinite life intangible assets outside of the required annual assessment if, among other things, we experience disruptions to the business, unexpected significant declines in operating results, divestiture of a significant component of the business, sustained decline in market capitalization or significant changes in macro-economic factors such as increased interest and discount rates. Our goodwill and indefinite life intangible assets are evaluated for impairment by first performing a qualitative assessment to determine whether a quantitative test is necessary. If it is determined, based on qualitative factors, the fair value of the reporting unit or indefinite life intangible asset may more likely than not be less than the carrying value, or if significant changes to macro-economic factors have occurred that could materially impact fair value, a quantitative impairment test would be required. The quantitative test is to identify if a potential impairment exists by comparing the fair value of a reporting unit or indefinite life intangible asset with its carrying value. If the carrying value of the reporting unit or indefinite life intangible asset exceeds the fair value, an impairment loss is recognized in an amount equal to that excess, not to exceed the carrying amount of goodwill or the indefinite life intangible asset. Our qualitative assessments for the first and second quarters of fiscal 2026 did not indicate that it was more likely than not the fair value of any of our reporting units or indefinite life intangible assets was less than the carrying amount, and as such, no quantitative test was deemed necessary. We consider reporting units and indefinite life intangible assets that have 20% or less excess fair value over carrying amount to have a heightened risk of impairment. One of our International reporting units, which had goodwill of $0.2 billion at March 28, 2026, was considered at heightened risk of impairment as of the date of the most recent estimated fair value determination which was in the fourth quarter of fiscal 2025. All of our other remaining reporting units and all our indefinite life intangible assets' estimated fair values exceeded their carrying values by more than 20% as of their most recent assessments. Although the remaining reporting units and indefinite life intangible assets had more than 20% excess fair value over carrying value as of the date of the most recent estimated fair value determination, they remain susceptible to impairments if any assumptions, estimates, or market factors significantly change in the future. Some of the inherent estimates and assumptions used in determining fair value of the reporting units and indefinite life intangible assets are outside the control of management, including interest rates, cost of capital, tax rates, market EBITDA comparables and credit ratings. While we believe we have made reasonable estimates and assumptions to calculate the fair value of the reporting units, it is possible a material change could occur. If our actual results are not consistent with our estimates and assumptions used to calculate fair value, it could result in material impairments of our goodwill or indefinite life intangible assets.

Goodwill and Intangible Assets

Goodwill and indefinite life intangible assets are initially recorded at fair value and not amortized, but are reviewed for impairment at least annually, or more frequently if impairment indicators arise. The first day of the fourth quarter is our annual impairment assessment date for goodwill and indefinite life intangible assets. However, we could be required to evaluate the recoverability of goodwill and indefinite life intangible assets outside of the required annual assessment if, among other things, we experience disruptions to the business, unexpected significant declines in operating results, divestiture of a significant component of the business, sustained decline in market capitalization or significant changes in macro-economic factors such as increased interest and discount rates.

Our goodwill and indefinite life intangible assets are evaluated for impairment by first performing a qualitative assessment to determine whether a quantitative test is necessary. If it is determined, based on qualitative factors, the fair value of the reporting unit or indefinite life intangible asset may more likely than not be less than the carrying value, or if significant changes to macro-economic factors have occurred that could materially impact fair value, a quantitative impairment test would be required. The quantitative test is to identify if a potential impairment exists by comparing the fair value of a reporting unit or indefinite life intangible asset with its carrying value. If the carrying value of the reporting unit or indefinite life intangible asset exceeds the fair value, an impairment loss is recognized in an amount equal to that excess, not to exceed the carrying amount of goodwill or the indefinite life intangible asset.

Our qualitative assessments for the first and second quarters of fiscal 2026 did not indicate that it was more likely than not the fair value of any of our reporting units or indefinite life intangible assets was less than the carrying amount, and as such, no quantitative test was deemed necessary. We consider reporting units and indefinite life intangible assets that have 20% or less excess fair value over carrying amount to have a heightened risk of impairment. One of our International reporting units, which had goodwill of $0.2 billion at March 28, 2026, was considered at heightened risk of impairment as of the date of the most recent estimated fair value determination which was in the fourth quarter of fiscal 2025.
