US antitrust regulators OK DuPont, Dow merger

OMAHA, Neb. — The long-delayed $62 billion merger of chemical giants DuPont and Dow has been approved by U.S. antitrust regulators. The Justice Department said Thursday it would approve the deal as long as the companies sell off some herbicide and chemical units to preserve competition. The merger was originally announced in December 2015 and was initially expected to close in the first half of 2016.
