In our audit, we do all of our auditing and our testing and everything to give a level of assurance that there is not an error greater than $1 billion. But that doesn't mean there can't be an accumulation of errors that are $300,000 or $400,000. And every audit works with that, because it would be impossible for us to audit everything. We can't audit everything, so to what level of precision do you then work?
