Summary of Significant Accounting Policies
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts disclosed in the financial statements and accompanying notes. Estimates, by their nature, are based on judgment and available information. Actual results could differ materially from those estimates.

Significant estimates inherent in the preparation of the accompanying unaudited consolidated financial statements include the assumptions used in the determination of the allowance for doubtful accounts receivable, impairment assessment of goodwill and indefinite-lived intangible assets, determination of the recoverability of long-lived assets, assessment of legal contingencies and calculation of income taxes.
Reclassifications
Certain historical financial information in the prior period consolidated financial statements has been reclassified to conform to the current period presentation. Historical segment financial information has been reclassified as a result of the organizational changes announced in December 2011 to reflect the realignment of the Company's reporting segments and centralization of certain support functions previously contained in the reporting segments (see Note 12).
