You answered it earlier, Bay Street, Wall Street.
Your best bet would be to ask the MM, what was his directive...
And of course with the full knowledge of Mr. Fung. I'm guessing the conversation went something like this: MacQuarie: In order to get this deal to work and unload all these shares, we need to ramp up the share price ahead of news and dump into volume before retail catches wind of the bought deal. Robert Fung..."of course we will delay the public release of any information pertaining to the bought deal until after you unload your shares on retail....or maybe it was just a wink and nod.
