Bayer shares plunge on Monsanto cancer payout

Shares in Bayer plunged more than 10 percent to their lowest in almost two years after a California jury ordered the German company's subsidiary Monsanto to pay $289 million in damages last week. As David Doyle reports, a jury found Monsanto liable in a lawsuit alleging that the company's glyphosate-based weedkillers, including its Roundup brand, caused cancer.
