We offer a defined contribution 401(k) retirement plan to substantially all of our U.S. employees. Participants may contribute from 1% to 90% of eligible compensation, inclusive of pretax and / or Roth deferrals (subject to Internal Revenue Service limitations), and we make matching contributions under this plan on the first 6% of the participant’s compensation (100% match of the first 3% employee contribution and 50% match on the next 3% contribution). Our matching contributions vest at a rate of 20% per year for each of the employee’s first five years of service and then are fully vested thereafter. We recognized expense of $0.8 million, $0.5 million and $0 related to matching contributions under our various defined contribution plans during the years ended December 31, 2019, 2018 and 2017, respectively.
