Stock-Based Compensation |
For the years ended December 31, 2012, 2011 and 2010, our total stock-based compensation expense was approximately $2.3 million, $3.6 million and $598,000, respectively. We have not recorded any income tax benefit related to stock-based compensation for the years ended December 31, 2012, 2011 and 2010.
A summary of the status of our stock options as of December 31, 2012, and changes during the year then ended, is presented below:
The weighted average grant-date fair value of options granted in 2012, 2011 and 2010 was $1.86, $2.22 and $1.13, respectively. During 2012, 1,232,001 stock options with an aggregate intrinsic value of $3,360,686 were exercised in exchange for issuance of 1,225,270 shares of our common stock, resulting in gross proceeds of $752,060. During 2011, 2,697,833 stock options with an aggregate intrinsic value of $9,620,085 were exercised in exchange for issuance of 1,832,673 shares of our common stock, resulting in gross proceeds of $225,010. During 2010, 491,667 stock options with an aggregate intrinsic value of $697,662 were exercised in exchange for issuance of 350,156 shares of our common stock, resulting in gross proceeds of $32,550. During 2012, 2011 and 2010, we paid tax withholdings related to stock options exercised of $9,000, $2.8 million and $133,000, respectively. During 2012, 2011 and 2010, the aggregate fair value of stock options vested was $460,000, $998,000 and $379,000, respectively.
A summary of the status of our unvested restricted stock as of December 31, 2012, and changes during the year then ended, is presented below:
During 2012 and 2011, 30,000 and 1,050,000 shares, respectively, of restricted stock vested with aggregate fair values of $85,000 and $4.2 million, respectively. No restricted stock vested during 2010.
As of December 31, 2012, there was approximately $2.2 million of total unrecognized compensation cost related to stock option and restricted stock awards, which we expect to recognize over remaining weighted average vesting terms of 2.0 years. See Note 1(e).
