14. Stock Incentive Plans

     Our Amended and Restated 2005 Long-Term Incentive Plan(“2005 Plan”) authorizes 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 (“1995 Plan”) and the Stock Plan for Non-Employee Directors. The options granted to officers and key employees under the 1995 Plan vested 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 $2,186,000and $12,694,000 for the three and six months ended June 30, 2013, respectively,and $2,311,000and $13,634,000for the same periods in 2012.
