Average Monthly Salary

When you become eligible for a Retirement Benefit, the average monthly salary is used in the calculation to determine your monthly benefit payment.

 Membership Tier 1

Highest average of 36 consecutive months of salary within the last 10 years of service.

 Membership Tier 2

Highest average of 60 consecutive months of salary within the last 10 years of service. 

 Membership Tier 3

 DB Members Only

Highest average of 60 consecutive months of salary within the last 10 years of service. 

Service Versus Credited Service

Your eligibility to receive a pension and how that benefit is calculated is based on two different service criteria:

Your eligibility to receive a normal pension is based on your service within the Plan.  Your service is all the time that is accounted for during your continuous employment and participation in the CORP.  Think of this as the running clock that starts when you first participate in the CORP and continues as long as you remain employed in a CORP designated position.

Credited service is that time while you participate in CORP that is covered by your contributions into the Plan, in addition to any redemption/transferring of eligible time.  So, any pay periods where you may have been on an unpaid leave is not considered credited service. Credited service is the time used to calculate your pension benefit.
