The Company has historically made matching contributions at a rate of $1.00 for each $1.00 of employee contribution, subject to a cap of 6% of the employee’s salary and federal limits. However, on April 1, 2020, in connection with other cost savings measures undertaken in response to declining demand for frac services as a result of the impacts of the COVID-19 pandemic, the Company suspended its matching contribution. Effective January 1, 2021 the Company restored its 6% matching contribution. Contributions made by the Company were $3.9 million and $4.2 million for the three months ended March 31, 2021 and 2020, respectively.
