As I understand things, the American HQ does not support financially countries once the work is 'established'. As a result if Norway ends up in the red, its will be allowed to die on the vine. And in the end we would expect the Norwegian Brothers to see more halls going up for sale and congregation mergers. But I do feel that there is a little more time before we see this happening, as the local Branch could start encouraging publisher 'donations' more ... or put higher levies on the assembly halls, to make up the difference.
Maybe they would try to move donations from Norway to another country so as to avoid paying tax on them.
They did lose charity status in France a few decades ago. They had to start paying fair 40% tax on all donations.
they sneakily moved everything to the UK and even tried to illegally move donations to the UK
