about buying two Japanese insurance units after talks stalled earlier this year,

A sale of AIG's Star Life and Edison Life operations may yield more than $3 billion, said one of the people, Bloomberg reports. A rival bid for the units from Manulife Financial is no longer under active discussion.

Prudential and AIG aren't close to reaching an agreement on a transaction, and the talks could fall apart, one of the people said, the news agency reports. Spokespeople for all the parties involved declined to comment.

A sale of the Japanese businesses could represent the biggest transaction since AIG was rescued from collapse by the U.S. government in September,
