During the three months ended March 31, 2012, we granted 190,886 stock options with an exercise price equal to the closing market price of a share of our Common Stock on the date of grant. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model, which resulted in a weighted average grant date fair value per share of $5.47. During the three months ended March 31, 2012, we also granted 83,489 shares of time-based restricted stock and 67,902 shares of total return-based restricted stock with weighted average grant date fair values per share of $32.18 and $38.71, respectively. We recorded stock-based compensation expense of $2.4 million and $2.0 million during the three months ended March 31, 2012 and 2011, respectively. At March 31, 2012, there was $9.4 million of total unrecognized stock-based compensation costs, which will be recognized over a weighted average remaining contractual term of 2.8 years.
