Pension Plan
Description of plan	Historically, the Company offered a noncontributory defined benefit retirement plan (the Pension Plan) that qualified under Section 401(a) of the Internal Revenue Code. The Pension Plan provided for a monthly payment, at normal retirement age of 65. Benefits were fully vested after five years of service. During the second quarter of 2009, the Company amended the Pension Plan to limit eligibility to employees hired prior to June 19, 2009. During the fourth quarter of 2012, the Company notified employees that the Pension Plan would be frozen for all participants on December 31, 2012.

SERP
Description of plan	The purpose of the SERP was to provide additional monthly pension benefits to ensure that each such senior management executive would receive lifetime monthly pension benefits equal to 3% of his or her final average compensation multiplied by his or her years of service (maximum of 20 years) to the Company or its subsidiaries, subject to a maximum of 60% of his or her final average compensation. The amount of a participant's monthly SERP benefit is reduced by (i) the amount payable under the Company's qualified Pension Plan (described above), and (ii) 50% of the participant's primary social security benefit. Final average compensation means the average of the 5 highest consecutive calendar years of earnings during the last 10 years of service prior to termination of employment. The SERP is an unfunded plan. Payments are made from the general assets of the Company. During the fourth quarter of 2012, the Company notified participants that the SERP would be frozen on December 31, 2012. Although no previously accrued benefits will be lost, participants will no longer accrue benefits for service subsequent to 2012.
