Buyout firm CVC Capital Partners has reappraised its plan for a leveraged buyout of Abertis Infraestructuras due to financing difficulties, and now is seeking to acquire about 20% of the highway operator from core shareholder Actividades de Construcción y Servicios, people familiar with the negotiations said Thursday.

A person familiar with the matter said that CVC sees the stake acquisition--estimated to be worth between €1bn ($1.3bn) and €1.5bn--as a way to get board representation at the Barcelona-based company, which it believes is in need of a major restructure. CVC and Abertis declined to comment.
