Description of the Business and Significant Accounting Policies

Principles of Consolidation

Principles of Consolidation. The consolidated financial statements include the accounts of SDI, together with its wholly and majority-owned or controlled subsidiaries, after elimination of significant intercompany accounts and transactions. Noncontrolling interests represent the noncontrolling owner’s proportionate share in the equity, income, or losses of the company’s majority-owned or controlled consolidated subsidiaries.

Use of Estimates

Use of Estimates. These financial statements are prepared in conformity with accounting principles generally accepted in the United States and, accordingly, include amounts that require management to make estimates and assumptions that affect the amounts reported in the financial statements and in the notes thereto. Significant items subject to such estimates and assumptions include the carrying value of property, plant and equipment, intangible assets and goodwill; valuation allowances for trade receivables, inventories and deferred income tax assets; income taxes; unrecognized income tax benefits; potential environmental liabilities; and litigation claims and settlements. Actual results may differ from these estimates and assumptions.

In the opinion of management, these financial statements reflect all normal recurring adjustments necessary for a fair presentation of the interim period results. These financial statements and notes should be read in conjunction with the audited financial statements and notes thereto included in the company’s Annual Report on Form 10-K for the year ended December 31, 2011.
