During fiscal 2020, 2019 and 2018, performance-based RSU equity awards that vest at the end of three-year performance periods were granted to the Company’s executive officers. The number of units that ultimately vest depends on the Company’s relative position as compared to its peers in achieving certain performance criteria and can range from 0% to 200% of the number of units granted. The performance criteria are total shareholder return, return on investment, SG&A expense containment and gross profit.
