9 .	Employee Benefit Plan

We have a defined contribution 401K 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, $7,800 and $7,650 for the years 2015, 2014 and 2013, 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, 2015, 2014 and 2013, we contributed to the Plan approximately $251,000, $181,000 and $134,000, respectively. No discretionary contributions have been made to the Plan since its inception.
