Aflac Ratings Lowered by S&P Following Downgrade of Japan Debt

Aflac Inc., the largest seller of supplemental health insurance, had its credit rating cut to A+ from AA- by Standard & Poor’s, which cited the company’s investments in Japan.

S&P, which had earlier downgraded Japan’s credit rating, said more than a third of Aflac’s invested assets remain in that nation’s government bonds, according to a statement issued Wednesday.
