OAK BROOK, Illinois (AP) — McDonald's Corp. says a key revenue figure edged up 0.5 percent in October, as better results in the U.S. and Europe offset a decline in Asia.

The world's biggest hamburger chain reported the gain in revenue at stores open at least 13 months for the period ended Oct. 31.

This figure is a key gauge of a retailer's health because it excludes results from stores recently opened or closed.

The metric rose 0.8 percent in Europe, led by the U.K., France and Russia. In the U.S., the metric edged up 0.2 percent on the strength of its Mighty Wings and Pumpkin Spice latte limited-time offers. It fell 2.8 percent in Asia/Pacific, the Middle East and Africa, hurt by weakness in Japan.

McDonald's shares fell 2 cents to $97.18 in premarket trading.
