The Sarbanes Oxley Act has driven yet another US company in to the arms of London's AIM.

According to this newspaper report, Viceroy Acquisition Corp, will list in London next month, eyeing a $200 million fund-raising as it tries to buy its way into the fast-growing U.S. biodiesel market.

Ok, they haven't said that's why they want to list in London, but it's what I consider likely. It has been an incredible turnaround from say 8 years ago, when the whole world wanted to list on NASDAQ. This shift to AIM has been quite pronounced in alternative energy where typically small firms, seeking relatively small amounts of capital, are in no need of onerous and expensive reporting requirements.

It just goes to show . . .

Whenever you raise the entry costs of doing business, you'll always drive some of it somewhere else.
