When I went I did economics at school the value of a company was 20 times the annual proft.
Because of the doubts over the future of online poker in the USA FT would be worth somewhat less than this.
I would assume if Stars did take them over they would immediately shut it down.
Possibly less, possibly more - it depends upon how "sexy" the business is, & how it fits in with current City Institutional thinking.
I think Rolls-Royce currently trades at about 15, with high street supermarket chains (mature markets, etc) at 12 or 13. It can be anything, really, but I'd assume a standalone Online Poker room would be single digits, after dicounting for lowered traffic patterns, legislative concerns, & the discount that all Gaming Companies are traded at.
I did some weird back-of-the-envelope numbers for FT whilst having a lie down just now, & I'd take a stab at 20% either side of $1 billion. That's not an offer, though. It's almost certainly complete bollox, too, but I can't be doing with numbers plucked out of the air, there has to be some foundation to them.
FT is rigged, of course. A bloke said as much next door, this week, so it must be true. He knew what he was talking about, too, he'd played live, several times, in Newcastle.
