Stock Incentive Plans

14. Stock Incentive Plans

     Our Amended and Restated 2005 Long-Term Incentive Planauthorizes up to 6,200,000 shares of common stock to be issued at the discretion of the Compensation Committee of the Board of Directors. The 2005 Plan replaced the 1995 Stock Incentive Plan and the Stock Plan for Non-Employee Directors. The options granted to officers and key employees under the 1995 Plan continued to vest through 2010 and expire ten years from the date of grant. Our non-employee directors, officers and key employees are eligible to participate in the 2005 Plan. The 2005 Plan allows for the issuance of, among other things, stock options, restricted stock, deferred stock units and dividend equivalent rights. Vesting periods for options, deferred stock units and restricted shares generally range from three years for non-employee directors to five years for officers and key employees. Options expire ten years from the date of grant. Stock-based compensation expense totaled $2,592,000 and $ 16,229,000 for the three and nine months ended September 30, 2012 and $1,767,000 and $ 9,041,000 for the three and nine months ended in September 30, 2011. The increase is primarily attributable to the impact of special non-cash retention and performance based stock awards for executive officers.
