AIG is in the middle of a turnaround after almost collapsing during the financial crisis under the weight of sour derivative bets. It has since repaid the $180 billion in bailout funds it received in 2008 and has focused on its core insurance business.

Net income attributable to AIG rose to $3.07 billion, or $2.10 per share, in the second quarter ended June 30 from $2.73 billion, or $1.84 per share, a year earlier.
The U.S. insurer's net income for the quarter included a $1.4 billion after-tax gain on the sale of ILFC.
On an operating basis, the company earned $1.83 billion, or $1.25 per share. The company reported after-tax operating income of $1.12 per share a year earlier.
Analysts on average had expected earnings of $1.05 per share, according to Thomson Reuters I/B/E/S.

The company's shares were trading at $53.69 after the bell.
