News Summary: McDonald's rolls out late-night menu

LATE NIGHT: McDonald's says participating 24-hour restaurants in the U.S. are rolling out an "After Midnight" menu this month that combines burgers with breakfast items. Customers can pick fries or hash browns as a side for a "Midnight Value Meal."

AVAILABILITY: The company, based in Oak Brook, Ill., didn't have an estimate of how many locations are participating. But it said about half its more than 14,000 U.S. locations are open around the clock.

GOING FORWARD: McDonald's has been testing a "Breakfast After Midnight" menu, as it looks to keep stores open longer. CEO Don Thompson also said in a CNBC interview earlier this year that the company is open to expanding breakfast beyond normal hours.
