NEW YORK (CNNMoney) -- The Federal Reserve made $82 billion in income in 2010, the central bank said Tuesday.
The Fed turns over most of its profits to Treasury in weekly remittances from the 12 regional Federal Reserve Banks to the government.
In 2010, the Fed sent almost all of its profit -- $79 billion -- to Treasury, a $32 billion increase from the amount transferred in 2009.
The increase in income was driven primarily by $24 billion in interest earnings on federal agency and mortgage backed security holdings.
Audited by Deloitte & Touche, the Fed's annual statement reveals the bank holds assets of $2.4 trillion.
Overall, the balance sheet reflects the massive amounts of bond and securitized mortgage products the Fed has snapped up in an effort to spur economic growth.
Holdings of U.S. Treasury securities increased $261 billion -- no surprise given the Fed's massive bond-buying program. Meanwhile, holdings of federal agency and mortgage backed securities increased $86 billion.
In January, the Fed announced a preliminary, unaudited profit of $81 billion.
