Consolidation, Policy [Policy Text Block]

Principles of Consolidation. The Condensed Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated. Non-controlling interest represents the minority shareholders’ proportionate share of the net assets and results of operations of the Company’s majority-owned subsidiaries.

Use of Estimates

Use of Estimates. The preparation of Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. The estimates and judgments affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to customer programs and incentives, intellectual property claims, product returns, allowance for doubtful accounts, inventories and inventory reserves, valuation and impairments of marketable securities and investments, impairments of goodwill and long-lived assets, income taxes, warranty obligations, restructuring, contingencies, share-based compensation and litigation. The Company bases estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying value of assets and liabilities when those values are not readily apparent from other sources. Actual results could materially differ from these estimates.
