The fair value of RSUs is based on the market price of the Company's common stock on the date of grant.  RSUs generally vest 25% annually over a four-year period from the date of grant. Upon vesting, the RSUs are net share settled to cover the required withholding tax with the remaining shares issued to the holder.  The Company recognizes compensation expense for such awards ratably over the corresponding vesting period.

Compensation Cost

The compensation cost that has been charged against income for stock awards under the 2009 Stock Option Plan, the 2014 Plan, the 2015 Plan, and the Company’s 2014 Employee Stock Purchase Plan, or ESPP, was $0.5 million and $0.4 million for the three months ended March 31, 2019 and 2018, respectively.  The total income tax benefit recognized in the statements of operations for share-based compensation arrangements was zero for the three months ended March 31, 2019 and 2018. Cash received from options exercised was zero for the three months ended March 31, 2019, and 2018.
