401K Plan

Our employees within the United States are eligible to participate in a 401(k) plan (the “Plan”) sponsored by us. These employees are eligible to participate upon employment hire date and obtaining the age of eighteen. All eligible employees may contribute a percentage of their compensation subject to a maximum imposed by the Internal Revenue Code. We match 100% of the first 3% of gross pay contributed by each employee and 50% of the next 4% of gross pay contributed by each employee. We may also make additional non-elective employer contributions at our discretion under the Plan. Similar benefit plans exist for employees of our foreign subsidiaries. During the three months ended June 30, 2018 and 2017, employer matching contributions totaled $0.9 million and $0.5 million, respectively. For the six months ended June 30, 2018 and 2017, employer matching contributions totaled $1.7 million and $0.9 million, respectively. Historically, we have not made non-elective employer contributions under the Plan.
