Mate if 75% of something is worth 45 million , simple math must say the the other 25% is worth 15 million . Currently the other 25% being TSN . Maybe i am not seeing the forest for the trees but it seems like CX must be selling their 75% at multiple x less than its current value if some people's assertations of TSN share price projections are to have much weight . Very happy to be wrong with this train of thought however .
