McDonald’s Corp. reported Monday a 5.1-percent increase in global same-store sales in May, which included a 2.8-percent bump in the United States.

Jim Skinner, president and chief executive of McDonald’s Corp., was selected as one of Brendan Wood International’s 66 TopGun CEOs, the corporate advisory firm said Friday.

McDonald’s Corp. would neither confirm nor deny on Tuesday the reported national introduction this summer of its long-tested Angus Third Pounder, a product rollout that sources say could spark some franchisee tension.
