To my knowledge, this is the first specific and detailed proposal we've had to cost, yes. In 2004, again, it was a general question from the committee, and we did our best in the available time.
It's important to recognize that small amounts of additional specificity can change the cost of the change by hundreds of millions of dollars. For example, whether it includes special benefits or not, what the benefit entitlement would be for the people who aren't being newly allowed into the program, these are things that weren't available at the time and we've made some assumptions about for this bill.
