These estimates may be adjusted due to changes in future economic, industry, or customer financial conditions, as well as changes in technology or demand. Estimates are used in accounting for, among other items, inventory reserves, restructuring reserves, warranty reserves, pension and post-retirement plans, stock-based compensation, useful lives for depreciation and amortization of long-lived assets, future cash flows associated with impairment testing for goodwill, indefinite-lived intangible assets and other long-lived assets, deferred tax assets, uncertain income tax positions, changes in tax laws, and contingencies. Management uses historical experience and all available information to make these estimates, including considerations for the impact of the COVID-19 pandemic on the macroeconomic environment. The situation related to the COVID-19 pandemic continues to be complex and dynamic. The Company cannot reasonably estimate the duration of the COVID-19 pandemic or fully ascertain its impact on the Company’s future results and market capitalization, which could adversely impact estimates such as the recoverability of goodwill and long-lived assets and the realizability of deferred tax assets. Actual results may ultimately differ from estimates, although management does not believe such differences would materially affect the financial statements in any individual year. Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the Consolidated Financial Statements in the period that they are determined.</span>
