I think the difficulty is that sometimes there is evidence or documentation of a liability, as it's commonly known. We've had witnesses before our committee telling us that there is an infrastructure deficit for many of the buildings the federal government owns in the amount of $4 billion. It's not accounted for anywhere. It's just a generally understood idea.
We could put that on the books. But if you don't contrast that with the current market value of those structures, you don't make wise decisions. We need to maintain the current market value estimates on the books somewhere, so that we don't make unwise decisions.
If we did a cost of purchase, all those structures may amount to $2 billion, so we say let's give these buildings away—but I'm just pulling numbers out of the air.
