Thank you.
What we put in the report was based on a survey that we had done of the department: the money that had already been spent and the money that they expected to spend. That was the $540 million. We asked them for their projections over a three-year time period.
Those were numbers that we put together. They weren't the numbers of the department. But even based on that, we felt that it was going to take longer. Again, remembering that what we're looking at is not just how long it's going to take to pay people the right amount on time, but also how long it's going to take to get to an efficient system. After the individual problems have been reduced, there will still be a lot of work to do to get the system to the point where it's efficient. That's why we believe it's going to cost more than the $540 million that the department told us they have either spent or plan to spend.
