| Description of defined contribution pension and other postretirement plans |
The Company sponsored a 401(k) retirement savings plan, which was categorized as a defined contribution plan. The plan was available to full time employees who met the plan’s eligibility requirements. The plan permitted employees to make contributions up to 15% of their annual salary with the Company matching up to the first 6%. The Company made monthly contributions (matching contributions) to the plan based on amounts contributed by employees. Subsequent to making the matching contributions, the Company had no further obligations. The Company might make an additional discretionary contribution annually if such a contribution was authorized by the Board of Directors. The plan was administered by an independent professional firm that specialized in providing such services.
