AIG agreed Monday to sell its American Life Insurance Co. unit to MetLife Inc. for $15.5 billion in cash and stock, in beleaguered AIG’s second sale of an international unit in a week.

AIG said it will sell the unit, known as Alico, for $6.8 billion in cash and the remainder in MetLife equity. The deal leaves AIG as the second-largest shareholder of MetLife, with a stake of more than 20% in the company.

Selling Alico, one of its largest international life insurance businesses, will allow government-controlled AIG to take yet another step in repaying the nearly $132 billion it borrowed from the federal government beginning in 2008 to avoid collapse.

Expected to close by the end of the year, the companies said the acquisition will also help MetLife, the largest seller of life insurance in the United States, grow internationally and especially target Japan.

The deal came a week after AIG announced an agreement to sell its Asian life insurance business, American Insurance Assurance Ltd (AIA), to Britain’s Prudential PLC in a deal valued at $35.5 billion, including $25 billion in cash.

AIG said it expects to generate about $50.7 billion from these two transactions, including approximately $31.5 billion in cash to repay the New York Federal Reserve Bank and another $19.2 billion in securities that it will sell over time to repay the government.
