Why are licences established in this way? For example, there is AIB plc, and then there is AIB, plc. Why would they not have really distinctive names or descriptions so that no one is confused? If we are to understand that that is a different company, one notes there is only a comma in the difference. Why is it structured like that? Why not create a clearly named entity that has no confusion? Even if the term "AIB" has to be used, it could be used in a better description.
