The expectations for 2020 contained in this Annual Report did not consider the unpredictable impacts at this moment of the pandemic of the coronavirus, Covid-19. Until the date of this report publication it wasn’t clear how extent this global outbreak would affect our business and the World economy. The authorities of the countries which we operate have adopted policies referring to the pandemic declared by the World Health Organization (WHO), such as the state of emergency declared by the Peruvian government. Threfore, untill this moment, we cannot predict the extent of the policies adopted or the impact they will may have on our business and operations. So we continue with the monitoring of the advances related to this outbreak.
