I notice that even when the BMG JV deal was announced on 20/4 there was no trading halt. That announcement including potential funding of $81m. Still, maybe it was all tied up quickly and no halt was needed. There was no halt called for the RMS JV or any other JV. Only for the options expiry underwriting.
All very interesting nevertheless, and there may still be a takeover offer as per Focker's original post on this thread. I guess we'll find out Tuesday.
