"Betfair Group plc Half year report for the six months ended 31 October 2010"
The Casino "Happy Hour" was mid November so no transactions would appear in these figures regardless of how they eventually chose to report it.
RE: Witholding it from Shareholders it is a Catch22 for them if they are as they claim to be innocent and not owing players anything there is no need to report it. If in fact they massively messed up, do in fact owe players £Millions, and have taken the money back illegally they would have to report it but by definition they are admiting they are in the wrong.
So they will not report it.
There is MUCH worse doctoring of figures goes on nobody bats an eye lid. I closed my (unfortunately small) short today at 1050p I think £10 will be a support level for psychological reasons. On a "value" approach I would not consider actually buying them at anything over £6 though.
