On September 29, 2011, 4,742 Survivors were likewise “grandfathered”. The chart above depicts enrollment from the beginning of the Program, starting with “grandfathered” members and the cumulative addition of new members each quarter. The date labels correspond to the end of the quarter (i.e., September 2018 represents cumulative members through March 31, 2018). Adjustments are made each quarter to account for member records changes
