Fed Line of Credit to AIG
The Fed originally created a credit-lending facility from which AIG was allowed to draw up to $85 billion. After a $40 billion loan from TARP funds, the Fed's line of credit was reduced to $60 billion.
Altogether, the Fed's actions should still achieve a total value of approximately $60 billion (minimum of $25 billion in revolving credit facility, $26 billion for in preferred interests in SPV, and $8.5 billion in new loans). The level of Fed funds currently committed through these channels is unknown.
Amount spent is current as of 1/19/2011 (http://www.federalreserve.gov/releases/h41/Current/). Activities of the Federal Reserve are not directly recorded in the federal budget. However, each year the Federal Reserve remits a portion of its earnings to the general treasury. This remittance is generally in the range of $20-$30 billion per year, but the CBO estimates that the Fed's earnings will be lower by approximately $90 billion over the next ten years.
