An investor group led by global private equity firm Advent International has signed a definitive agreement to acquire a 22 percent interest in Colombia-based Oleoducto Central, a crude oil transportation system, from oil and gas companies Talisman Energy, Total Colombia Pipeline and Compañía Española de Petróleos. Talisman will receive US$595 million for selling its 12 percent stake. Two of Colombia’s pension funds, Sociedad Administradora de Fondos de Pensiones y Cesantías Porvenir and Administradora de Fondos de Pensiones y Cesantías Protección, will join Advent in the deal through a co-investment fund formed by Advent. The transaction is subject to customary closing conditions and is expected to take place within the next few weeks.
