Foundation Member Eligibility for Retirement

To be entitled to retirement benefits, a member must have a minimum of three years of contributory service. Unreduced retirement benefits are available once you reach your normal retirement age or meet the requirements for special early retirement. Under special early retirement, you become eligible for unreduced retirement benefits when certain combinations of age and years of service are met (i.e. meeting your Rule). Reduced retirement benefits can be drawn once you attain your minimum retirement age. No retirement benefits are payable to you before you attain your minimum retirement age.

Early Retirement - Percent of Benefit Payable: If you do not meet the requirements for special early retirement, you may choose to begin drawing your retirement benefit prior to reaching your normal retirement age at a reduced rate. The amount of reduction depends upon your age and years of credited service when payments begin. If you choose to retire prior to your normal retirement age, your benefits will be permanently reduced by 1/4 of 1% for each full month (or 3% for each full year) between your benefit commencement and the date you will reach your normal retirement age or the date you will meet your special early retirement requirements, if applicable.
