Exactly my thoughts about this as well, never seen such a comment, since they haven't commented on it I guess no one never have given it much attention. I still think this could be a question at the next CC.
It's all there on page 38 in the 10-Q for Nov -15. As I read we need to pay 1.25M$ to own 75% of PF1, 9.77M$ to have 75% of PF2. For WXC businesses&NaWei wholesale center, total consideration amount isn't established(work in progress until end of -15) so no plans when the 10-Q was written. Hopefully this will be established when the 10-K arrives....next week?!
