Quite a lot of them seem are being used for tax- or debt-dodging purposes, by enabling franchise-holders to declare bankruptcy. The key thing to look for is a near or total absence of marketing, especially when they are not situated in prime locations. They will normally have two franchises on the go, one offering English such as Scholastic Early English (USA), the other offering mathematics such as I-Wang (South Korea). Do I think the franchise-owning companies are bothered about their brands being used in such a way? I think they really don't care as long as they've got money coming in the door, be it short-term quick hits or long-term bigger bucks. Franchise-holders declare bankruptcy within 5 to 9 months, so you might not get your final salary.
