Pursuant to our Amended and Restated Incentive Compensation Plan, we can grant stock-based awards in the form of restricted stock, restricted stock units, and stock options to team members, officers, directors, and contractors. Instead of a short-term compensation program providing for rolling, annual equity awards to our executive officers and senior leaders, we utilize a multi-year compensation program that grants a one-time equity award at the beginning of the compensation program period that is intended to incentivize recipients over the multi-year compensation period. Our current compensation program for executive officers and senior leaders covers the 2025 through 2034 compensation period and included a one-time equity award in December 2024 (except in the case of our Chief Executive Officer, who received a one-time equity award in January 2025), with a vesting period of 10 years. Based on the stock-based awards that are currently outstanding, we expect to recognize future stock-based compensation expense as follows:
