Supplemental employee retirement plan.The Company maintains supplemental employee retirement plans (each, a “SERP”) with certain of its employees (each, a “Participant”). Under the SERPs, if the Participant remains in continuous service with the Company for a period of at least 30 years, the Company will pay to the Participant a supplemental retirement benefit for the 15-year period following the Participant’s retirement equal to 50% of the Participant’s highest average annual base salary for five consecutive years in the 10-year period preceding the Participant’s retirement. If the Participant retires prior to the later of age 65 or the completion of 30 years of continuous service with the Company, but has completed at least 10 years of continuous service with the Company, the amount of the supplemental retirement benefit will be reduced by 1/360th for each month short of 30 years that the Participant was employed by the Company.
