The U.S. comparable sales figure includes, among other things, the effect of recent gasoline price inflation, with the average sales price per gallon of gasoline up 27% for the five-week month of December. Excluding gasoline price inflation, U.S. comparable sales would have been up 4%. In addition, foreign exchange rates, particularly in Canada and the U.K., positively impacted international comparable sales results. On a local currency basis, international comparable sales increased 5% in December.
