We recognized gains on the change in the fair value of Equator earn out liability of $7.6 million and $37.9 million for the years ended December 31, 2015 and 2014, respectively (no comparative amount in 2013). The liability for contingent consideration is reflected at fair value and adjusted each reporting period with the change in fair value recognized in earnings. In 2015, we reached an agreement with the former owners of Equator to extinguish any liability for the Equator Earn Out. In connection with this settlement, we reduced the liability for the Equator Earn Out to $0 and recognized a $7.6 million increase in earnings. During 2014, the fair value of the contingent consideration related to the Equator acquisition was reduced by $37.9 million with a corresponding increase in earnings based on management’s revised estimates that expected earnings of Equator will be lower than projected at the time of acquisition.
