stock-based compensation

On March 13, 2015, we granted 192,589 restricted stock units with a total fair value of $6.7 million to certain employees under an existing stock-based compensation plan. The units will vest three years from the date of grant, in March 2018, and are expected to be amortized over the vesting period. We recognize compensation expense based on estimated grant date fair values for all share-based awards issued to employees and directors. The total compensation expense was $1.9 million and $5.2 million for the three and nine months ended September 30, 2015, respectively. The total compensation expense was $1.9 million and $5.6 million for the three and nine months ended September 30, 2014, respectively.
