Note 7. Accounting for Stock-Based Compensation

The Company recognized stock-based compensation expense of $3.9 million and $2.0 million for the three months ended March 31, 2014, and March 31, 2013, respectively. Unrecognized compensation expense of $18.5 million as of March 31, 2014, related to unvested stock options and unsettled restricted stock units (“RSUs”), is expected to be recognized over a weighted-average period of approximately 2.06 years. The unrecognized compensation expense related to cash-settled RSUs (“CSRSUs”) totaled approximately $10.0 million at March 31, 2014 and is expected to be recognized over a weighted-average period of approximately 3.4 years. During the three months ended March 31, 2014, the Company granted approximately 0.3 million shares in the form of equity compensation, including stock options, and stock-settled RSUs, and granted approximately 0.1 million shares in the form of CSRSUs to its employees. As of March 31, 2014, the Company had approximately 1.8 million shares available for grant under its 2010 Omnibus Incentive Plan, as amended. CSRSUs have no impact on the shares available for grant under the 2010 Omnibus Incentive Plan, and have no impact on the calculated shares used in earnings per share calculations.
