16.          Stock Based Compensation

We account for share-based awards in accordance with ASC 718, Compensation-Stock Compensation, which requires the fair value of stock-based compensation awards to be amortized as an expense over the vesting period. Stock-based compensation awards are valued at fair value on the date of grant.

For the three and nine months ended September 30, 2014, we expensed $1.5 million and $2.7 million, respectively, for stock option grants, compared to $1.9 million and $4.7 million, respectively, during the same periods in 2013. We expensed $0.7 million and $2.0 million for restricted stock awards during the three and nine months ended September 30, 2014, respectively, compared to $1.1 million and $3.5 million, respectively, during the same periods in 2013.
