The Company maintains a qualified defined-contribution plan under the provisions of the Internal Revenue Code Section 401(k), which covers substantially all employees in the United States who meet certain eligibility requirements.

The Company matches 100% of the participant’s first 3% of deferrals and 50% of the next 2% deferral percentage. The Company’s portion is 100% vested at the time of the match.

The aggregate amounts charged to expense in connection with the plan were $1,382,  $1,049 and $824 for the years ended December 31, 2016, 2015 and 2014, respectively.
