The Company recognizes excess tax benefits associated with share-based compensation to shareholders’ equity (deficit) only when realized. When assessing whether excess tax benefits relating to share-based compensation have been realized, the Company follows the with-and-without approach. Under this approach, excess tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits available to the Company, which are also subject to applicable limitations. As of both September 30, 2016 and December 31, 2015, the Company had $25.4 million of unrealized excess tax benefits.
