In the statement they said they were a "USA incorporated not-for-profit organization" which already manages operations between Canada (like you said) and the US. It also mentioned that the names, brand, trademark, intellectual property and anti-trust will be managed by the new belgian entity. There's nothing wrong with that. It sounds like the move is partially motivated by legal reasons. As an amateur who likes to know the details of laws, I'm interested what the differences are between their current legal entity and the new belgian one.
