Valvoline, an American manufacturer and distributor of Valvoline-brand automotive oil, additives, and lubricants, is set to demerge its Retail Services and Global Products businesses. Financial terms were not disclosed. "Following a comprehensive review of strategic alternatives by the Valvoline Board of Directors and executive management, we believe that a separation of our business segments will create significant and sustainable value for our shareholders, employees and other stakeholders, and will best position the Retail Services and Global Products businesses for continued long-term success," Stephen F. Kirk, Valvoline Chairman of the Board.
