) Employee Benefit Plans
 
Supplemental employee retirement plan
.
We have Retirement Security Agreements (each, a “SERP”) with certain of our employees (each, a “Participant”). Under the SERPs, if the Participant remains in continuous service with us for a period of at least
30
 years, we will pay them a supplemental retirement benefit for the
15
-year period following their retirement equal to
50%
of their highest average annual base salary for
five
consecutive years in the
10
-year period preceding their retirement. If the Participant retires prior to the later of age
65
or the completion of
30
 years of continuous service with us, but has completed at least
10
years of continuous service, the amount of their supplemental retirement benefit will be reduced by
1/360th
for each month short of
30
 years that they were employed by us.
 
Net periodic
pension cost for the SERPs includes the following components:
