In December 2017, the Company adopted the Inari Medical, Inc. 401(k) Plan which allows eligible employees after one month of service to contribute pre-tax and Roth contributions to the plan, as allowed by law. The plan assets are held by Vanguard and the plan administrator is Ascensus Trust Company. Beginning in January 2021, the Company contributes a $1.00 match for every $1.00 contributed by a participating employee up to the greater of $3,000 or 4% of eligible compensation under the plan, with such Company's contributions becoming fully vested immediately. For the three months ended March 31, 2022 and 2021, the Company recognized $1.7 million and $0.8 million in matching contributions expense.
