| Share-Based Payments                                                          | Share-Based PaymentsIn February 2014, we issued 0.6 million of restricted stock awards to members of our management team and our board of directors. Approximately 0.2 million of these awards contain only a service condition, while the remainder contain both a service and a performance or market condition. For the awards that include a performance or market condition, the number of shares that will ultimately be granted to employees may vary based on the Company’s performance during the applicable two-year performance measurement period. Additionally, in February 2014, we granted 0.1 million stock options to members of our management team. The fair value of these awards and options was determined using the policies described in Note 1, Summary of Significant Accounting Policies, and Note 13, Share-Based Payments, to the consolidated financial statements accompanying the 2013 Form 10-K. |
