haris, I think this is because the plant was already manufacturing the aerial films before Agfa Photo's collapse, the APX films were made elsewhere. Even if they had the formulae they wouldn't have the experience to immediately manufacture APX type film without R&D and trials.

One problem with the repackaged Agfa-Gevaert - Rollei film is it isn't cheaper than existing Ilford, Fuji and Kodak B&W films and offers photographers no real advantages, except for a Tech Pan alternative.
