Hereby we inform as a Relevant Information Communication that, today, during the Council Session of the Provincial Municipality of Trujillo, the project “Integrated Collection System and Fleet Control for Trujillo City” was awarded to our subsidiary GMD S.A. for a period of twenty years. This project derived from the private initiative presented by our subsidiary and declared of interest on June 17, 2014.

The concession’s objective is the operation of the Integrated Collection System for the entire city of Trujillo, which includes commercial network, bus fleet, cards, a control center for drivers, as well as inspection, user information, among others.

The estimated initial investment for the first three years is US$ 22 million. Nonetheless, we have committed to renew the equipment due to its wear down for common use. Such technological renovation is estimated at US$ 18 million, which will be paid in the following eight years.

The signing of the contract is expected to take place during the second week of December. Once the contract is signed, we will proceed to notify it as a Relevant Information Communication.
