Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and the instructions to Form 10-Q and, therefore, reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. These interim condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Prior period segment data has been restated to reflect the Company's revised reportable segment structure. See Note 2, "Segment Results" for a discussion of the change in reportable segments. Recent Accounting Pronouncements In July 2012, the Financial Accounting Standards Board ("FASB") issued amended guidance to simplify how entities test indefinite-lived intangible assets for impairment. The amendments permit an entity to first assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired and whether it is necessary to perform the quantitative impairment test for indefinite-lived intangible assets required under current accounting standards. The amendments are effective for annual and interim impairment tests of indefinite-lived intangible assets performed for fiscal years beginning after September 15, 2012 with early adoption permitted. The Company performs its assessment of intangible assets on an annual basis and does not expect the amended guidance to have a material impact on its consolidated financial position, results of operations, cash flows and disclosures.
