Share-Based Compensation | 6. Share-Based Compensation The Company maintains stock incentive plans pursuant to which it can grant restricted shares, unrestricted shares, incentive stock options, non-qualified stock options, restricted stock units (“RSU’s”), performance stock units (“PSU’s”) or stock appreciation rights (“SAR’s”).
