On December 14, 2011, the FTSE Group published the results of its market consultation on the minimum free float requirements for inclusion of premium London-listed companies in the FTSE UK Index Series – one of the most recognized indices in the world, which includes the FTSE 100 Index. The key outcome of the consultation is that, as of January 1, 2012, the minimum free float required for UK-incorporated companies will increase from 15% to 25%, with grandfathering of existing FTSE companies until January 1, 2014.
