This year our U.S. business is poised to hit major milestones, surpassing $5 billion in earned premium and $1 billion in pretax earnings. With Dan and I committed to several more years in our existing roles, it's an opportune time to expand Paul's responsibilities. We look forward to the contributions that he will make working both with Aflac Japan – which generates more than 75 percent of our earnings – and with our global investment division." Regarding Janke, Dan Amos said: "Ken has done an outstanding job of working with Kriss as deputy CFO since September 2010.

In addition, she has a strong commitment to customer service when it comes to serving our policyholders, shareholders and sales force.
