You should check the settlement terms and you will find the AWP adjustment applies to about 1442 NDCs. FDB and Medi-Span independent of the settlement announced they will adjust AWPs for all other NDCs who's markup is greater than 1.20 (about 15-20K NDCs).
Also, FDB was alleged to have inflated AWPs and Medi-Span was alleged to have continued reporting them after the SEC divested the FDB/Medi-Span merger (Medi-Span was owned by FDB during the alleged activity).
