Bentonville, Ark., Wal-Mart Stores CEO Lee Scott said the company is adopting a cautious stance, considering that rising fuel prices could mean this year will not be easy.
"With fuel pries going up, it feels like it's going to be a challenging year," he said on Tuesday during a television interview on Fox News.
"I wouldn't say worried is the right word. But I think we're cautious thinking through what it means. Fuel prices have an impact on our basic customer," he added.
Wal-Mart has been struggling to revive sales at its U.S. store base, which have been hurt by lackluster shopper response to its efforts to sell trendy clothing and a disruptive store-remodeling program.
