Sales in the company's North American snack business rose 3 percent. The division, which accounted for 21 percent of total sales in fiscal 2013, has been a bright spot for Pepsi, helping its stock vastly outperform that of larger rival Coca-Cola in the past year.  Pepsi's chief financial officer, Hugh Johnston, told CNBC it was a "terrific quarter."  "PepsiCo really does have a lot of momentum, both in terms of our large customers and our small customers. The business is really performing well right now," he said Wednesday in an interview with "Squawk on the Street."  He also thinks lower gas prices will begin to help, but said the process is evolutionary in nature and will build slowly.  "History tells us it will take about six to eight months to fully feel that affect and I expect that will happen again this time."  However, he told Reuters macroeconomic conditions remained tough and that the stronger dollar was a challenge for everybody.  The dollar has surged about 20 percent against a basket of major currencies, making overseas sales denominated in other currencies less valuable in dollar terms.  Pepsi's net revenue for the fourth quarter ended Dec. 27 fell about 1 percent to $19.95 billion, hurt mainly by a stronger dollar.
