Cost of Benefits

The Company’s policy is to fund the pension plan at or above the minimum level required by law. The Company made $64,000 and $141,000 of contributions to its defined benefit pension plan during the nine months ended September 30, 2012 and 2011, respectively. Changes in the discount rate and actual investment returns that are lower than the long-term expected return on plan assets could result in the Company making additional contributions.
