Canada's Couche-Tard raises bid for Casey's

Convenience-store operator Alimentation Couche-Tard Inc. raised its bid for Casey's General Stores by almost 5 percent in its latest effort to win over shareholders.

Russian drought pushes up global food prices

International food prices have risen to their highest level in two years, fueled in part by a drought in Russia that lifted the cost of wheat, a U.N. agency said. The Rome-based U.N. Food and Agriculture Organization said its food price index shot up 5 percent between July and August. But that was still 38 percent down from its peak in June 2008. Drought in Russia -- and the country's subsequent restrictions on wheat exports -- forced a sudden sharp rise in wheat prices, the agency said.
