401(k) Savings Plan

Effective January 1, 2018, the Company adopted the 2018 401(k) Plan, a defined contribution plan under Section 401(k) of the Internal Revenue Code, whereby the Company provides matching contributions of 100% of each employee's contribution up to a maximum matching contribution of 3% of the employee's eligible compensation and at a rate of 50% of each employee's contribution in excess of 3% up to a maximum of 5% of the employee's eligible compensation.

Prior to January 1, 2018, the Company had a defined contribution plan that was managed by the CRL 401(k) Plan. Effective January 1, 2018, employees' and former employees' accounts were transitioned from the CRL 401(k) Plan to the 2018 401(k) Plan. Under the CRL 401(k) Plan, the Company provided matching contributions up to 50% of actual dollars contributed, not to exceed a maximum of 6% of gross wages, subject to certain time-based vesting requirements.

Total employer matching contributions related to these plans were $0.9 million, $0.4 million, and $0.1 million respectively, for the years ended December 31, 2019, 2018, and 2017.
