RETIREMENT AND OTHER POSTRETIREMENT BENEFIT PLANS

The Corporation sponsors the Retirement Income Plan (RIP), a qualified noncontributory defined benefit pension plan that covered substantially all salaried employees hired prior to January 1, 2008. The RIP covers employees who satisfy minimum age and length of service requirements. During 2006, the Corporation amended the RIP such that effective January 1, 2007 benefits were earned based on the employee's compensation each year. The plan amendment resulted in a remeasurement that produced a net unrecognized service credit of $14,079, which had been amortized over the average period of future service of active employees of 13.5 years. The Corporation's funding guideline has been to make annual contributions to the RIP each year, if necessary, such that minimum funding requirements have been met. The Corporation amended the RIP on October 20, 2010 to be frozen effective December 31, 2010, at which time the Corporation recognized the remaining previously unrecognized prior service credit of $10,543 as a reduction to expense.

The Corporation also sponsors two supplemental non-qualified retirement plans. The ERISA Excess Retirement Plan provides retirement benefits equal to the difference, if any, between the maximum benefit allowable under the Internal Revenue Code and the amount that would be provided under the RIP, if no limits were applied. The Basic Retirement Plan (BRP) is applicable to certain officers whom the Board of Directors designates. Officers participating in the BRP receive a benefit based on a target benefit percentage based on years of service at retirement and a designated tier as determined by the Board of Directors. When a participant retires, the basic benefit under the BRP is a monthly benefit equal to the target benefit percentage times the participant's highest average monthly cash compensation during five consecutive calendar years within the last ten calendar years of employment. This monthly benefit was reduced by the monthly benefit the participant receives from Social Security, the RIP, the ERISA Excess Retirement Plan and the annuity equivalent of the three percent automatic contributions to the qualified 401(k) defined contribution plan and the ERISA Excess Lost Match Plan. The BRP was frozen as of December 31, 2008. The ERISA Excess Retirement Plan was frozen as of December 31, 2010.

The Corporation's subsidiaries participate in a qualified 401(k) defined contribution plan under which eligible employees may contribute a percentage of their salary. The Corporation matched 50 percent of an eligible employee's contribution on the first 6 percent that the employee deferred through December 31, 2010. Beginning in 2011, the Corporation matches 100% of the first four percent that the employee defers. Employees are eligible to participate upon their first day of employment or having attained age 21, whichever is later. In 2007, the Corporation began making an automatic two percent contribution and may make an additional contribution of up to two percent depending on the Corporation achieving its performance goals for the plan year. Effective January 1, 2008, in lieu of the RIP benefit, the automatic contribution for substantially all new full-time employees was increased from two percent to four percent. Beginning in 2011, substantially all employees will receive an automatic contribution of three percent of compensation at the end of the year. The Corporation's contribution expense was $4,069 and $2,500 for the six months ended June 30, 2011 and 2010, respectively.

The Corporation also sponsors an ERISA Excess Lost Match Plan for certain officers. This plan provides retirement benefits equal to the difference, if any, between the maximum benefit allowable under the Internal Revenue Code and the amount that would have been provided under the qualified 401(k) defined contribution plan, if no limits were applied.

The Corporation sponsors a pre-Medicare eligible postretirement medical insurance plan for retirees of certain affiliates between the ages of 62 and 65. During 2006, the Corporation amended the plan such that only employees who were age 60 or older as of January 1, 2007 are eligible for employer paid coverage. The Corporation has no plan assets attributable to this plan and funds the benefits as claims arise. Benefit costs related to this plan are recognized in the periods in which employees provide service for such benefits. The Corporation reserves the right to terminate the plan or make plan changes at any time.
