WASHINGTON (AP) -- Mortgage giant Fannie Mae said Wednesday that it lost money in the fourth quarter and is asking the federal government for nearly $4.6 billion in aid to cover its deficit. Washington, D.C.-based Fannie said it lost roughly $2.4 billion in the October-December quarter, stung by declining home prices. Revenue was about $4.5 billion. The government rescued Fannie and sibling company Freddie Mac in September 2008 to cover their losses on soured mortgage loans. Since then, a federal regulator the Federal Housing Finance Agency has controlled their financial decisions. Taxpayers have spent more than $150 billion to prop up Fannie and Freddie, the most expensive bailout of the 2008 financial crisis. The government estimates that figure could top $259 billion to support the companies through 2014 after subtracting dividend payments. Fannie has received more than $116 billion so far from the Treasury Department, the most expensive bailout of a single company........... If only they had been better "regulated"
