Simple Cost-Of-Living Adjustments (COLAs) are payable on July 1 for retirees who have been on the ATRS payroll for twelve months or longer.
Simple COLAs are calculated on the retirees' base amount, which is the original amount the retiree received when he or she retired, plus any ad hoc raises received as a result of legislation. The base amount does not include cost-of-living raises.
