McDonald's same-store sales up 1.4 percent in February

Shares in the company -- one of the restaurant industry's top performers -- were up 1.2 percent in morning trade.

The company booked higher sales despite having one fewer day in February, since 2008 was a Leap Year. The loss of that one day cut about 4 percentage points from same-store sales, the company said on Monday.

Still, McDonald's cautioned that at current currency exchange rates the stronger dollar would cut first-quarter earnings by 7 to 9 cents a share.
