OAK BROOK, Ill. — Global comparable sales at McDonald’s Corp. increased 3.3 percent, or 5.6 percent in constant currencies, in May.

“Our commitment to providing customers with menu variety, value and convenience delivered global comparable sales growth in May despite the increasingly challenging global economic environment,” said Jim Skinner, chief executive officer. “I am confident we will continue to deliver long-term sustainable growth as we remain focused on the opportunities that will enable brand McDonald’s to further extend our relevance to the 68 million customers who we serve around the world every day.”
