Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation: The consolidated financial statements include the accounts of the company and its wholly owned subsidiaries and include all adjustments, which were of a normal recurring nature, necessary to present fairly the financial position of the company as of March 31, 2013, the results of its operations for the three months endedMarch 31, 2013 and changes in its cash flow for the three months ended March 31, 2013 and 2012, respectively. Certain foreign subsidiaries, represented by the European segment, are consolidated using a February 28 quarter end in order to meet filing deadlines. No material subsequent events have occurred related to the European segment, which would require disclosure or adjustment to the company's financial statements. All significant intercompany transactions are eliminated.  The results of operations for the three months endedMarch 31, 2013 are not necessarily indicative of the results to be expected for the full year.

Use of Estimates

Use of Estimates: The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from these estimates.

Stock-Based Compensation

Stock-Based Compensation Plans: The company accounts for share-based compensation under the provisions of Compensation-Stock Compensation, ASC 718. The company has not made any modifications to the terms of any previously granted options and no significant changes have been made regarding the valuation methodologies used to determine the fair value of options granted. The company continues to use a Black-Scholes valuation model.

The substantial majority of the options awarded have been granted at exercise prices equal to the market value of the underlying stock on the date of grant. Restricted stock awards granted without cost to the recipients are expensed on a straight-line basis over the vesting periods.

The amounts of stock-based compensation expense recognized were as follows (in thousands):

	Three Months Ended March 31,
	2013		2012
Stock-based compensation expense recognized as part of selling, general and administrative expense	$	1,160	$	1,534

The amounts above reflect compensation expense related to restricted stock awards and nonqualified stock options awarded under the 2003 Performance Plan (the “2003 Plan”). Stock-based compensation is not allocated to the business segments, but is reported as part of All Other as shown in the company's Business Segment Note to the Consolidated Financial Statements.
