Aflac said its pre-tax investment losses for the quarter were $83 million.
Certain investments, including some in European financial firms, resulted in losses of $390 million. That was offset by $307 million in pre-tax gains from the sale of U.S. and Japanese government securities and other Portuguese bank holdings.
Total revenue climbed 11 percent to $6 billion. Sales of group products to larger employers helped Aflac grow U.S. revenue 4 percent.
Premium income from Japan rose 16.3 percent, from sales growth and a stronger yen.
Japan accounts for around 70 percent of Aflac’s business, showing few signs of disruption from the island nation’s devastating March earthquakes and tsunami.
Aflac Chairman and CEO Dan Amos said the company set a fourth-quarter dividend of 33 cents, a 10 percent increase.
