OAK BROOK, ILL. — McDonald’s Corp. on Sept. 9 said global comparable sales increased 2.2% in August and 4.2% year-to-date. System-wide sales for restaurants worldwide, meanwhile, increased 1.1%, or 4.1% in constant currencies.

"Our commitment to providing customers with menu variety, value and convenience is delivering sustained global comparable sales growth despite the current economic environment," said Jim Skinner, chief executive officer. "Our system remains aligned behind providing great service to each of the 58 million customers who visit us daily."

Comparable sales at the Oak Brook-based fast-food chain rose 1.7% in the United States in August behind the strength of the new premium Angus Third Pounders and McCafe espresso-based coffees.

European comparable sales were up 3.5% due to the company’s tiered menu approach, which includes locally relevant limited-time food offerings, and popular marketing tie-ins. Also in August, McDonald’s said comparable sales fell 0.5% in Asia/Pacific/Middle East and Africa. The segment’s performance was adversely affected by China, Japan and several other markets, McDonald’s said.
