Retirement savings plan - Note 15 | 15. Retirement savings plan We have a retirement savings plan that qualifies under Internal Revenue Code Section 401(k). The plan covers all qualified employees. Contributions to the plan by the Company are made at the discretion of the Board of Directors. In March 2012, the Company discontinued discretionary matching contributions. Prior to March 2012, we matched 50% of employee contributions to the plan up to 6% of the employee's per pay period compensation. During 2012 and 2011, we contributed $44,000 and $242,000, respectively, to the plan under the matching program.
