I fully agree with the last part, that the return on actions from budget 2013 was $1.57 billion. In my remarks, I mentioned that was actually three times larger than the estimate we had at the front. I would love to say that return on investment was on a $15-million investment, but that would not be an accurate portrayal. It was largely a result of the rebuilding of our approach to audit, and in particular, under the leadership of people like Ted Gallivan, our new integrated risk assessment system to audits. This is a system within the agency that is used in our approach to large companies, those over $250 million in revenue, and it's based on a math algorithm with 200 variables.
In other words, we have gotten better and better, through business intelligence, in where we focus our audit assets, and that came into effect right around that time, so that, along with the tools, produced the kind of revenue gain you referred to, sir.
