BOSTON (Reuters) - Third Point LLC has agreed to pay more than $600,000 to settle allegations the hedge fund failed to properly file for antitrust clearance when it bought DowDuPont stock two years ago, the U.S. Justice Department said on Wednesday. Third Point, which invests roughly $15 billion in securities around the world and is run by billionaire investor Daniel Loeb, will pay a civil fine of $609,810, the department said. Two years ago the hedge fund allegedly bought too much DowDuPont stock too quickly, failing to make the required Hart-Scott-Rodino filings or observe a required waiting period.
