Retirement Plan
The Company has established a defined-contribution plan under Section 401(k) of the Internal Revenue Code (the “401(k) Plan”). The 401(k) Plan covers all employees who meet defined minimum age and service requirements, and allows participants to defer a portion of their annual compensation on a
pre-tax
basis. As currently established, the Company is not required to make any contributions to the 401(k) Plan. The Company contributed $0.2 
million during each of the three months ended March 31, 2021 and 2020.
