Share-Based Compensation

In June 2015, the Company’s shareholders approved an amendment to the 2011 Stock Incentive Plan (Plan). The approved amendment increased the number of shares authorized for issuance under the Plan by 70 million and removed the limit in the Plan for shares other than options and stock-settled stock appreciation rights (SARs) that can be awarded. The Company’s outstanding share-based awards consist mainly of nonqualified stock options, SARs and restricted stock and restricted stock units (collectively, restricted shares). As of June 30, 2015, the Company had 85 million shares available for future grants of share-based awards under its share-based compensation plan.
