Note 14 — Retirement Plans

The Company maintains a defined contribution plan for the benefit of its U.S. employees. The plan is intended to be tax qualified and contains a qualified cash or deferred arrangement as described under Section 401(k) of the Internal Revenue Code. Eligible participants may elect to contribute a percentage of their base compensation, and the Company may make matching contributions, generally equal to fifty cents for every dollar employees contribute, up to three percent of the employee’s eligible compensation, as limited by current Internal Revenue Code regulations. Generally, the plan calls for vesting in the Company contributions over the initial five years of a participant’s employment. The Company provided employer contributions associated with this plan of approximately $2.6 million, $2.4 million, and $2.4 million for the years ended December 31, 2021, 2020, and 2019, respectively.
