Effective December 31, 2012, the qualified defined benefit pension plan was frozen resulting in no benefits accruing after December 31, 2012. Employees will have an accrued benefit which will be paid upon retirement, or for deferred vested participants, at the time they request and are eligible for their pension benefit.

The Corporation also maintains a retirement savings plan under Section 401(k) of the Internal Revenue Code of 1986, as amended, covering substantially all full-time and part-time employees beginning in the quarter following three months of continuous employment. The savings plan was approved for non-vested employees in the defined benefit pension plan and new hires as of January 1, 2007. Effective January 1, 2009, the Corporation suspended its matching contribution to the savings plan. Effective April 1, 2011, the Corporation reinstated its matching contribution at $.50 of each $1.00 up to 1% of an employee's qualifying salary. Starting January 1, 2013, the employer's matching contribution to the savings plan increased to 100% on the first 3% and then 50% on the next 2% of the employee's qualifying salary. Matching contributions vest in accordance with plan specifications.
