Burger King, the global fast food chain, third-quarter profits fell 24% on higher interest costs. However, it reported an improvement in its operating performance, with same-store sales up 1.6%, driven by international business. In Latin America, same-store sales grew by 11%, and they were up 3% across Europe, the Middle East, Africa and Asia Pacific. In the U.S. and Canada, same-store sales were relatively flat. Burger King said its profit fell to $48.1m in the latest period from $63.4m a year earlier. Revenue increased 1.4% to $608.m. However, the company's interest expenses nearly quadrupled to $48m. Income from operations, before the interest expense, was up 25% due to the higher sales and a 2.9% drop in operating costs. The company underwent a global restructuring initiative to cut costs recently.
