Share Plans [Abstract]
Share Plans	12. Share Plans During the first quarter ended March 31, 2013, approximately 442,000 restricted stock awards vested. As permitted by the Company’s equity incentive plan, these restricted stock awards were net-share settled such that the Company withheld shares with a value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes. In effect, the Company repurchased, and classified as treasury stock, 162,819 of the issued shares at fair value (total cost of $6,543), and used the cash on behalf of the employees to satisfy the tax withholding requirements. This tax amount, together with an additional $4,716 of taxes paid related to the net share settlement of stock option exercises during the first two quarters of 2013, is reflected as a cash outflow in the financing section of the condensed consolidated statement of cash flows. Excess tax benefits of $8,401 were recorded during the first two quarters of 2013 as a result of the stock activity discussed above. This amount is reflected as a cash inflow in the financing section of the condensed consolidated statement of cash flows.
