Stock-Based Compensation Stock-Based Compensation
The Company has historically issued three types of stock-based compensation: time-based awards, long-term incentive plan (“LTIP”) awards and performance-based stock compensation plan (“PSP”) awards. Time-based awards are equity awards that tie vesting to length of service with the Company and generally vest over a four-year period in annual and/or quarterly installments. LTIP awards are performance-based equity awards that are used to establish longer-term performance objectives and incentivize management to meet those objectives. PSP awards are performance-based equity awards which establish performance objectives related to one or two particular fiscal years. LTIP awards generally vest when revenue and/or Adjusted EBITDA targets are achieved amongst other conditions, while PSP awards generally vest upon achievement of revenue and/or Adjusted EBITDA targets and have a range of payouts amongst other conditions. All stock-based compensation awards expire seven to ten years after the grant date thereof.
