Hyundai Oilbank Co., South Korea's fourth-largest oil refiner, is planning to list its shares on the country's main bourse next year, its chief said Thursday. "The plan still depends on market situations but we are hoping to list shares before the first half of next year," Hyundai Oilbank CEO Kwon Oh-gap told reporters after a ceremony kicking off operations at its second heavy-oil processing plant in Daesan, a coastal city 137 kilometers southwest of Seoul.
