Vesting determines when an employee has earned the right to receive pension benefits. The following formula must evaluate to TRUE for the employee to be vested:

service_credits >= 10

Retirement eligibility determines when an employee can begin receiving pension payouts. The following formula must evaluate to TRUE:

commencement_age >= 60 AND service_credits >= 10

Formula Variables:

  • service_credits: Years of credited service
  • commencement_age: Age when pension payments commence

The annual pension benefit is calculated as:

Annual Benefit = Final Compensation × Benefit Factor × Service Credits

Final compensation is the salary figure used in the benefit calculation, typically an average of the employee’s highest-earning years.

FieldValue
MethodHighest Consecutive Years
Years Averaged5

The benefit factor is a percentage multiplier that typically varies based on retirement age. Higher ages generally yield higher factors.

MIN(0.80 / service_credits, CASE
WHEN commencement_age < 60 OR service_credits < 10 THEN 0.0
WHEN service_credits >= 30 THEN 0.01625 +(MIN(commencement_age, 67) - 60) * 0.00125
ELSE 0.0145 +(MIN(commencement_age, 67) - 60) * 0.0015
END)

Formula Variables:

  • commencement_age: Age when pension payments commence
  • service_credits: Years of credited service

The COLA formula determines how pension benefits grow over time after retirement to keep pace with inflation.

current_pension_benefit + 0.03 * MIN(13000, current_pension_benefit)

Formula Variables:

  • initial_pension_benefit: The annual benefit amount at retirement
  • years_since_retirement: Number of years since retirement began

Pension payouts from this plan are taxable as ordinary income.
