Share-Based Compensation The Company has share-based compensation plans, which are more fully described in Note 9, Share-Based Compensation, to the Consolidated Financial Statements in the 2012 10-K. During the three months ended March 31, 2013, the Company granted stock awards subject to continued service, consisting of stock appreciation rights, or SARs, and stock units with vesting terms fully described in the 2012 10-K. There were no stock options granted during the three months ended March 31, 2013. For the three months ended March 31, 2013 and 2012, share-based compensation expense amounted to $7.9 million and $7.2 million, respectively. As of March 31, 2013, the total unrecognized compensation cost related to all non-vested stock awards was $43.2 million and the related weighted-average period over which it is expected to be recognized is approximately 1.4 years. The following tables summarize the activity under all share-based compensation plans for the three months ended March 31, 2013:

The Company recognizes excess tax benefits associated with share-based compensation to shareholders’ equity only when realized. When assessing whether excess tax benefits relating to share-based compensation have been realized, the Company follows the with-and-without approach. Under this approach, excess tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits available to the Company, which are also subject to applicable limitations. As of March 31, 2013, and December 31, 2012, the Company had $26.0 million and $25.9 million, respectively, of unrealized excess tax benefits. |
