The Pension Plan is a defined benefit plan that uses a formula based on earnings and service to determine the monthly retirement benefit.

Earnings are determined by averaging the highest 2 of the last 5 years of employment and generally include base pay, longevity and under certain circumstances assignment pay.

Years of service are converted to a service accrual factor equal to 3% multiplied by the first 25 years of service and 2.5% for every year thereafter with a maximum accrual factor of 90%.

Service accrues from the pension entry date until the termination of employment. The accrual of service credit is prorated right down to the termination date including fractional parts of months and years. It is unnecessary to work through an anniversary date to earn a full year of service credit or a full month to receive credit for that month.

When selecting a retirement date for normal retirement benefits, termination of employment must occur on or after the first day of the month following either attainment of age 55 or completion of 30 years of service regardless of age, whichever comes first. After then employment may terminate on any day.

Examples of retirement calculations are found within the Summary Plan Description and Member's Handbook.
