The survey is obligatory. Under the law they must, or are supposed to, respond to the survey. What we really ask for is only the first point outside the country where you invested.
Occasionally we try to look through those financial centres—whether on an island in the Caribbean, in Luxembourg, or Holland—to get information about the destination of the final investment. But we don't always get that additional information; we try to perceive it.
That's an international issue, and right now we're trying internationally to find new methods. Many other countries would like to be able to see from the ultimate investor all the way through to the final destination of investment.
I'm working on a committee at the OECD that's trying to investigate how we might find measures to do that.
