RELEVANT INFORMATION

Bogotá, February 12, 2018. Grupo Aval Acciones y Valores S.A. ("Grupo Aval") informs the following with respect to the investment in Concesionaria Ruta del Sol S.A.S (“CRDS”):

Episol S.A.S. (“Episol”), a wholly-owned subsidiary of Corficolombiana S.A. carried out an impairment analysis regarding its investment in CRDS, a company in which it participates with 33% of its share capital, reflecting an adjustment in December 2017 of COP$140,691 million (approx. USD$47 million). This deterioration in the investment value is in addition to the one effected by Episol in 2016 of COP$ 102,275 million (Approx. USD$34 million). The balance of this investment after the impairment is COP$ 111,783 million (approx. USD$37 million), which is equivalent to the present value of the capital contributions made by Episol in CRDS as of December 2017.

This adjustment represents an impact on Grupo Aval's attributable net income of approximately COP$63,000 million (approx. USD$21 million), reflected in its financial statements as of December 31, 2017.

The matters referring to the request for the declaration of Ruta del Sol Sector 2 Contract ("Concession Agreement") as null and void, the mutual claims of the parties, the termination and liquidation agreement executed on February 2017, the liquidation value of the works and the amounts to be recognized are all subject to an Arbitration Tribunal that will resolve the differences between CRDS and the National Infrastructure Agency (“ANI”).

Although no award has been issued and the date on which it will be issued is uncertain, Episol considered it was appropriate to make the mentioned impairment on the value of its investment. Notwithstanding the foregoing, Episol will continue to defend its legitimate rights and interests in the arbitration proceeding, and in any other forum.
