The U.S. comparable sales figure includes, among other things, the effect of gasoline price inflation, with the average sales price per gallon of gasoline up 17% for the four-week month of April, as compared to the year-earlier April. Excluding gasoline price inflation, U.S. comparable sales would have been up 5%. In addition, foreign exchange rates, primarily in Canada, positively impacted international comparable sales results. On a local currency basis, international comparable sales increased 6% in April.
