12. EMPLOYEE BENEFIT PLANS

The Company has four qualified non-contributory defined benefit pension plans covering a significant majority of its employees and an unfunded plan that provides benefits in excess of amounts allowable under current tax law in the qualified plans. The Company closed enrollment in its pension plans to salaried employees hired after December 31, 2005, to Fernandina hourly employees hired after April 30, 2006, to Jesup hourly employees hired after March 4, 2009 and to Wood Products hourly employees hired after February 28, 2011. Currently, all plans are closed to new participants. Employee benefit plan liabilities are calculated using actuarial estimates and management assumptions. These estimates are based on historical information, along with certain assumptions about future events. Changes in assumptions, as well as changes in actual experience, could cause the estimates to change.

The net pension and postretirement benefit costs that have been recognized during the stated periods are shown in the following table:
