The Federal Reserve Bank of New York has sold the last remaining securities associated with the 2008 AIG bailout, securing a healthy profit for US taxpayers.

The wind-down of the Maiden Lane III portfolio means the bank has realised a net profit of $US17.7 billion ($17 billion) with its assistance of AIG and related facilities.

“The completion of the sale of the Maiden Lane III portfolio marks the end of an important chapter – our assistance to AIG – that was undertaken to stabilise the financial system in the midst of the financial crisis,” Federal Reserve Bank of New York President William C Dudley said.

Net proceeds from past sales, plus cash flow the securities generated while held by the portfolio, allowed the full repayment of the bank’s loan, plus interest, on June 14 and AIG’s equity contribution to the portfolio, plus interest, on July 16.
