10 . | Employee Benefit Plan
We have a defined contribution 401(k) plan (the “Plan”) covering substantially all of our employees. In the past three calendar years, we made matching cash contributions equal to 50% of each participant’s contribution during the Plan year up to a maximum amount equal to the lesser of 3% of each participant’s annual compensation or $7,950, $7,950 and $7,800 for the years 2016, 2015 and 2014, respectively. Such amounts were recorded as expense in the corresponding years. We may also contribute additional discretionary amounts to the Plan as we may determine. For the years ended December 31, 2016, 2015 and 2014, we contributed to the Plan $0.6 million, $0.3 million and $0.2 million, respectively. No discretionary contributions have been made to the Plan since its inception.
