Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Compensation expense associated with common stock, RSUs and restricted stock was recognized based on the fair value of the instruments, over the instruments’ vesting period. Stock based compensation expense increased by $0.8 million for the year ended December 31, 2014 from the same period in 2013 primarily due to amortization reflecting new grants with a total fair value (net of estimated forfeitures) of $2.7 million under the 2011 LTIP in the third quarter of 2013. Stock based compensation expense for the year ended December 31, 2012 included a benefit of $0.4 million for forfeitures under the 2011 LTIP associated with the departure of two former executives and $0.2 million for the modification of the 2011 LTIP. The increase in stock based compensation expense related to the Board of Directors for the year ended December 31, 2014 from the same period in 2013 reflects the compensation increase for Board of Director members effective in the third quarter of 2013.
