Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | 18. Incentive Plans The Company maintains two equity participation plans, the Second Amended and Restated 1998 Equity Participation Plan (the “Prior Plan”) and the 2010 Equity Participation Plan (the “2010 Plan”) (collectively, the “Plans”). The Prior Plan provides for a maximum of 47,000,000 shares of the Company’s common stock to be issued for qualified and non-qualified options and restricted stock grants. Effective May 1, 2012, the 2010 Plan provides for a maximum of 10,000,000 shares of the Company’s common stock to be issued for qualified and non-qualified options and other awards, plus the number of shares of common stock which are or become available for issuance under the Prior Plan and which are not thereafter issued under the Prior Plan, subject to certain conditions. Unless otherwise determined by the Board of Directors at its sole discretion, options granted under the Plans generally vest ratably over a range of three to five years, expire ten years from the date of grant and are exercisable at the market price on the date of grant. Restricted stock grants generally vest (i) 100% on the fourth or fifth anniversary of the grant, (ii) ratably over three or four years, (iii) over three years, at 50% after two years and 50% after the third year or (iv) over ten years at 20% per year commencing after the fifth year. Performance share awards may provide a right to receive shares of restricted stock based on the Company’s performance relative to its peers, as defined, or based on other performance criteria as determined by the Board of Directors. In addition, the Plans provide for the granting of certain options and restricted stock to each of the Company’s non-employee directors (the “Independent Directors”) and permits such Independent Directors to elect to receive deferred stock awards in lieu of directors’ fees. The Company recognized expense associated with its equity awards of $11.7 million and $9.6 million for the six months ended June 30, 2012 and 2011, respectively. As of June 30, 2012, the Company had $38.3 million of total unrecognized compensation cost related to unvested stock compensation granted under the Plans. That cost is expected to be recognized over a weighted average period of approximately 4.0 years. The Company, from time to time, repurchases shares of its common stock in amounts that offset new issuances of common shares in connection with the exercise of stock options or the issuance of restricted stock awards. These repurchases may occur in open market purchases, privately negotiated transactions or otherwise, subject to prevailing market conditions, the Company’s liquidity requirements, contractual restrictions and other factors. During the six months ended June 30, 2012, the Company repurchased 1.5 million shares of the Company’s common stock for $29.0 million, of which $7.2 million was provided to the Company from options exercised. During the six months ended June 30, 2012, the Company expensed $3.8 million relating to severance costs associated with employees that have been terminated during 2012; $2.5 million of these severance costs related to the departure of an executive officer during January 2012.
