The Company uses the same accounting policies in preparing quarterly and annual financial statements. Unless otherwise noted, amounts presented within the Notes to condensed consolidated financial statements refer to the Company’s continuing operations. Note 1 Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the accompanying notes, and the reported amounts of revenue and expenses during the reported periods. Actual results could differ materially from those estimates. On an ongoing basis, management evaluates its estimates, including those related to warranty obligations, sales commission, allowance for credit losses, and sales allowances, valuation of inventories, fair value of goodwill, useful lives of property and equipment, impairment testing for long-lived-assets, incremental borrowing rates related to the Company’s leases, assumptions regarding variables used in calculating the fair value of the Company's equity awards, expected achievement of performance based vesting criteria, management performance bonuses, fair value of investments, the standalone selling price of the Company's products and services, the period of benefit used to capitalize and amortize contract acquisition costs, variable consideration, contingent liabilities, recoverability of deferred tax assets, and effective income tax rates. Management bases estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
