extended its streak of positive same-store sales results to 20 months in a row in November, beating expectations.

The burger giant said sales at restaurants open at least a year rose 4.2% in November over the same month last year, slightly higher than consensus estimates. Comps were up 7.1% in the U.S. and 1.1% in Europe. Total sales for the month rose 9.3%.

"Our performance in the U.S. continues to be driven by multiple complimentary initiatives including new food, expanded restaurant hours, everyday value, appealing Happy Meals and better operations," the company said in a statement.

For the fourth quarter, it said it expects to record after-tax impairment charges of $85 million to $100 million, or 7 to 8 cents a share, related to South Korean assets.

The positive sales results came despite some recent turmoil in McDonald's executive offices. The author of the company's turnaround plan, CEO Jim Cantaloupo, died from a heart attack in April. His replacement, Charlie Bell, resigned earlier this month because of health complications and was replaced by the current head, Jim Skinner.

The stock was recently down 14 cents, or 0.4%, to $31.36.
