Basis of Presentation [Abstract]
Basis of Presentation	Basis of Presentation. The condensed consolidated financial statements are unaudited. Because of the nature of the Company’s operations, the results for interim periods are not necessarily indicative of results to be expected for the year. While these condensed consolidated financial statements reflect all normal recurring adjustments that are, in the opinion of management, necessary for fair presentation of the results of the interim period, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (GAAP) for complete financial statements. Therefore, the interim condensed consolidated financial statements should be read in conjunction with the consolidated balance sheets as of December 31, 2014 and 2013, and the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the three years in the period ended December 31, 2014 and the notes thereto included in the Company’s Annual Report filed on Form 10-K for the year ended December 31, 2014, and other subsequent filings with the SEC. Revisions of prior period financial statements: In the first quarter of 2014, the Company recorded an out-of-period 2013 adjustment to income taxes, which had the effect of increasing income tax expense and reducing net income and income from continuing operations by $1.6 million, or approximately $0.03 per diluted share. In the course of preparing the Company’s financial statements for the year ended December 31, 2014, the Company identified immaterial misstatements in certain deferred tax accounts related to prior periods. In connection with the correction of these misstatements, which were reflected in the Company's 2014 Form 10-K, the Company also corrected for the 2013 out-of-period income tax adjustment by retroactively adjusting income taxes for the first quarter of 2014, which increased net income and income from continuing operations by $1.6 million, or approximately $0.03 per diluted share, from the results previously reported in the Company's Form 10-Q for the quarter ended March 31, 2014. The impact of the adjustments had no impact on pre-tax income or cash flows from operating, investing or financing activities. Rounding: Amounts in the condensed consolidated financial statements and notes are rounded to the nearest tenth of a million, but per-share calculations and percentages were determined based on amounts before rounding. Accordingly, a recalculation of some per-share amounts and percentages, if based on the reported data, may be slightly different.
