Share-based Compensation [Abstract] |
Share-Based Compensation | Share-Based Compensation In May 2005, the Company adopted the 2005 Plan which succeeded a prior plan. A maximum of 4,957,250 shares of common stock under the 2005 Plan are authorized for issuance upon exercise of options, stock appreciation rights and other awards, or upon vesting of restricted or deferred stock awards. As of December 31, 2012, only options and restricted stock awards have been granted under these plans. Beginning January 1, 2008, options granted, for which the Company has recognized share-based compensation expense become exercisable at a rate of 25% per year beginning one year from the date granted, are granted at the market price on the date of grant, and expire after 10 years. Prior to January 1, 2008, shares became exercisable at a rate of 20% per year. Cash received from option exercises was $2,492,000, $1,951,000, and $733,000 during 2012, 2011, and 2010, respectively. Total compensation costs were $168,000, $439,000, and $651,000 during 2012, 2011, and 2010, respectively. The excess tax benefit realized for the tax deduction from option exercises of the share-based payment awards totaled $86,000, $56,000, and $132,000 during 2012, 2011, and 2010, respectively. No stock options were awarded in the past three years. A summary of the stock option activity under the Company’s plans as of December 31, 2012 and changes during the year then ended is presented below:
