Burger King will soon come under Brazilian ownership in a deal valued at $4 billion (U.S.), which includes the assumption of debt. The buyout marks the largest leveraged acquisition of a fast-food chain ever, and the second for Burger King in the last eight years.

The new owner, 3G Capital, is backed by a number of wealthy Brazilians and plans to expand Burger King’s foothold internationally, especially in Latin America and Asia. The fast-food chain has struggled in North America, where it generates 70% of its revenue, Meat Trade News Daily reports.
