One of the most successful banks in the U.S. is the Federal Reserve. The securities that it bought during the financial crisis, among other investments, are paying off.

The Fed paid an estimated $77.7 billion to the Treasury Department last year according to a news release on its website http://www.federalreserve.gov/newsevents/press/other/20140110a.htm

While this payment is less than that in 2012, the Fed has transferred funds to the Treasury every year since 1934.
