NEW YORK (AP) — Hess has reached a deal with a major investor to end a bitter fight over the management and direction of the oil and gas company.

The investor, Elliott Management, a hedge fund based in New York that holds 4.5 percent of Hess shares, accused CEO and Chairman John Hess of badly mismanaging the company’s assets and consistently making poor strategic decisions. It highlighted the personal ties of Hess board members to the Hess family, and accused the board of lax oversight of the company.
