If I purchase Plan E Elective COLA and then decide to transfer prospectively to Plan D, what happens?
If you transfer prospectively to contributory Plan D, you retain your Plan E service credit and your Plan E Elective COLA purchase contract remains in effect. Payroll deductions on your contract continue until the contract is completed. At retirement, the allowance you are entitled to under each Plan will be calculated separately, based on service credit earned under each Plan. Your monthly retirement allowance will reflect the total of the Plan D and Plan E amounts.
