Syngenta AG agreed to pay more than $1.4 billion to U.S. farmers who complained that the marketing of the company’s genetically modified corn seeds shut them out of the Chinese market, according to people familiar with the deal. The settlement with more than 100,000 farmers was announced Tuesday in a Minnesota class-action trial. It resolves all farmers’ litigation in the U.S. but doesn’t include Canadian lawsuits, according to Paul Minehart, a Syngenta spokesman. Minehart wouldn’t confirm the amount of the settlement, saying the terms will be made public when the deal is presented to a judge.The pact resulted from months of negotiations between a four-lawyer team representing farmers and Syngenta’s attorneys, according to the people familiar, who said they weren’t authorized to speak publicly about the settlement. Syngenta halted the trial involving about 22,000 Minnesota farmers to announce the deal. Those farmers were seeking more than $400 million in damages over their corn losses.
