so, first post here. shareholder since early summer. been lurking for several months and appreciate everyone's input, and looking forward to the coming march madness, doc style. one thing i'd love to figure out is the shares outstanding question. td ameritrade says 181 million, otc markets says a whole bunch more, but that was as of 2014. so called td today, on hold for an hour, and rep claimed their info would be from market maker, and then he checked yahoo to confirm which seemed kinda odd. yahoo the gold standard? i'm much happier with the 181mm, and 14.4mm market cap, but not entirely confident they have accurate info. anyone here been able to verify current shares outstanding number?
