Significant Judgments, Estimates and Assumptions |
Significant Judgments, Estimates and Assumptions | 3. Significant Judgments, Estimates and Assumptions The preparation of financial statements in conformity with US GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to estimates include the recoverable amounts of goodwill and the preliminary purchase price allocation for the acquisition of IAA. Accounting for business combinations requires estimates with respect to the fair value of the assets acquired and liabilities assumed. Such estimates of fair value require valuation methods, which rely on significant estimates and assumptions, especially for acquired intangible assets. In connection with the IAA purchase price allocation, the valuation of intangible assets required significant estimates and assumptions, and the valuation of property, plant, and equipment, and operating lease right-of-use assets also required estimates and assumptions. The valuation of customer relationship intangible assets was performed using a method of the income approach and required significant estimates and assumptions regarding revenue growth rates, and discount rates, and the valuation of other acquired intangible assets was performed using a method of the income approach and required estimates and assumptions regarding revenue growth rates, royalty rates, customer attrition rates and discount rates, as applicable. The Company based these estimates on historical and anticipated results, industry trends, economic analysis, and various other assumptions, including assumptions as to the occurrence of future events. The valuation of most acquired property, plant, and equipment, other than land, was performed using a method of the cost approach and required certain estimates and assumptions regarding replacement cost and adjustments to account for physical deterioration and obsolescence. The fair value of most acquired land and the off-market component of right-of-use assets were estimated using a method of the market approach and included certain estimates and assumptions with respect to market value or market rents, growth rates, and discount rates, as applicable.
