On October 7, 2008, the Federal Reserve further expanded the collateral it will loan against to include commercial paper using the new Commercial Paper Funding Facility (CPFF). The action made the Fed a crucial source of credit for non-financial businesses in addition to commercial banks and investment firms. Fed officials said they'll buy as much of the debt as necessary to get the market functioning again. They refused to say how much that might be, but they noted that around $1.3 trillion worth of commercial paper would qualify. There was $1.61 trillion in outstanding commercial paper, seasonally adjusted, on the market , according to the most recent data from the Fed. That was down from $1.70 trillion in the previous week. Since the summer of 2007, the market has shrunk from more than $2.2 trillion. This program lent out a total $738 billion before it was closed. Forty-five out of 81 of the companies participating in this program were foreign firms. Research shows that Troubled Asset Relief Program (TARP) recipients were twice as likely to participate in the program than other commercial paper issuers who did not take advantage of the TARP bailout. The Fed incurred no losses from the CPFF.
