Critical Accounting Estimates
We have identified the policies below as critical to our business operations and to the understanding of our results of operations. We have discussed the impact and any associated risks on our results of operations related to these policies throughout the MD&A. For a detailed discussion on the application of these and other accounting policies, see Note 1 to the Consolidated Financial Statements.
The preparation of our financial statements in conformity with GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. These estimates include, but are not limited to, customer cancellations, bad debts, inventory obsolescence, residual values of leased assets, useful lives of long-lived assets and intangible assets, warranty obligations, restructuring, pensions and other postretirement benefits, contingencies and litigation, and allocation of purchase price to tangible and intangible assets acquired in business combinations. Our actual results could differ from those estimates and assumptions. We believe the assumptions and estimates used are reasonable and appropriate in accordance with GAAP.
