"All of the company's operating divisions successfully navigated through an environment of higher input costs in order to deliver balanced top- and bottom-line performance. "In PepsiCo International, broad-based volume gains in snacks and beverages coupled with foreign currency tail winds resulted in continued double-digit revenue and operating profit growth. Favorable foreign currency upsides allowed us to reinvest in several international markets in the quarter. In North America, our profit growth accelerated to 7%. Frito-Lay's strong performance continued, and 7% profit growth in our domestic beverage business marked another quarter of sequential improvement.
