ITV took the step of buying out all of their US shareholders (actually very few, and due to an acquisition of some sort, I believe), delisting, and deregistering from the SEC. Expensive, but less so than SOX compliance, they reckoned.
You can only do that as FPI if you can afford to ignore the American market, of course - otherwise you get seen as a niche player.
@Whomp - prolly just a terminology thing, but I guess you mean the privately owned sector, rather than the private sector ? Frankly, I think that's a wimp's approach for a CFO. If you reckon you're good enough to play in the big leagues, then you should be able to deal with Sarbanes-Oxley as a CFO. It's kind of like asking to get put back down to triple-A cos your batting average looks better.
