Like two weeks of annual vacation and casual Fridays, filing financial statements in XBRL isn't a custom likely to catch on at British companies any time soon. The Financial Services Authority—the UK's answer to the SEC—recently felt it necessary to reiterate its disinterest in the programming language. Despite "a number of regulatory bodies" (read: the SEC) championing XBRL, the "cost and risk" of introducing the technology for corporate filers do not outweigh the benefits, the FSA said.
So, it looks like XBRL superfan Christopher Cox won't enjoy the same "special relationship" with his opposite number in London, John Tiner, as that between Bush and Blair. Of course, look where that got poor Tony.
