Sun Life is no longer in the life reinsurance business. That part of its business has now been sold to Berkshire Hathaway Life.

According to Sun Life, the decision to sell was based on the company’s continued strategy of focusing “its activities and deploying capital to key businesses that can best achieve strong, sustainable growth.”

Based in Nebraska, Berkshire Hathaway is a holding company managing a number of subsidiary companies. With Warren Buffett as its chairman and CEO, Berkshire Hathaway owns everything from railroads to many electric and gas utilities.
