Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

We currently have a single stock incentive plan, the 2011 Incentive Plan, amended during the second quarter of 2013, for the granting of equity-based incentive awards. We grant time- and/or performance-vested restricted stock and/or restricted stock units, in addition to stock options, to key employees and members of our Board of Directors. The performance measures for vesting of restricted stock and restricted stock units for grants to management for the periods presented are based on earnings growth, return on invested capital, total shareholder return, income from operations as a percent of revenue and income before tax. Awards granted under the 2011 Incentive Plan were as follows:
