It doesn’t occur to many investors in the U.S. that some businesses have considerable international operations. One great example is AFLAC (NYSE: AFL), which actually offers more of its insurance-based products in the Japanese market than it does domestically. That has been a problem when the U.S. dollar is strong, but recently, the yen has strengthened, and coming into Thursday’s third-quarter financial report, Aflac investors fully expect that the company would finally reap the rewards of currency exposure.
