Sherwin-Williams Co., NL Industries Inc. and ConAgra Grocery Products LLC were ordered by a judge to pay $1.1 billion to replace or contain lead paint in millions of homes after losing a public-nuisance lawsuit brought by 10 California cities and counties. Superior Court Judge James Kleinberg in San Jose, California, on Tuesday tentatively ruled against the companies after a non-jury trial that lasted about five weeks. Two other defendants, Atlantic Richfield Co., a Los Angeles-based unit of BP Plc, and Wilmington, Delaware-based DuPont Co., won dismissal of the claims against them.
