Employee Benefit Plan |
Employee Benefit Plan | 15. Employee Benefit Plan In January 2012, we adopted a 401(k) retirement and savings plan (the "401(k) Plan") covering all employees. The 401(k) Plan allows employees to make pre-tax contributions up to the maximum allowable amount set by the Internal Revenue Service. Under the 401(k) Plan, we may make discretionary contributions as approved by our board of directors. During the years ended December 31, 2014, 2013 and 2012, we made contributions to the 401(k) Plan of $0.2 million, $0.1 million, and $0.1 million, respectively.
