Eversheds has sealed one of its largestever instructions for trophy client DuPont opposite Allen & Overy (A&O), advising the giant US chemicals company on the $3bn (£1.7bn) refinancing of its European arm.

The deal, which closed on 20 October, is the first major piece of finance work the firm has handled for the Fortune 500-listed client, which uses Eversheds for all of its UK advice.
