Not that this is unexpected but buried within this data:

Fannie slashed its net worth, or the difference between assets and liabilities, to $9.4 billion on Sept. 30 from $44.1 billion at Dec. 31. The company said today it may fall to negative net worth by the end of next quarter, requiring it to seek government funding. Fannie said today that it hadn't tapped any federal aid through Nov. 7

Fannie Mae may have negative net worth by the end of next quarter.

Now that raises an eyebrow.

They slashed their asset evaluations by $21 Billion and I'm assuming that is after the loosing of the mark-to-market accounting rules via the SEC.
