Subsequent Event

(11) Subsequent Event: In the fourth quarter of 2011, the Company adopted plan amendments to freeze its traditional defined benefit pension plan for non-bargaining unit employees. Effective January 1, 2012, the traditional defined benefit plan formula will be transitioned to a cash balance formula, and no further benefits will be accrued under the defined benefit plan formula. Under the cash balance formula, the Company provides an annual retirement benefit equal to 5 percent of an employee's eligible cash compensation, plus interest based on the 10-year U.S. Treasury Note.
