The Company recognizes excess tax benefits associated with share-based compensation to shareholders’ (deficit) equity 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 June 30, 2014 and December 31, 2013, the Company had $18.2 million and $15.4 million, respectively, of unrealized excess tax benefits.
