Our portfolio in Mexico, counting the 760 new towers added during the year, is the largest in the country, and we have outpaced our competitors both in terms of tower construction and overall growth in recent years. In Costa Rica, since we first began operations in this country, we have added 268 towers to the portfolio and continue to work on increasing the number of co-locations.
During 2017 we also increased the number of clients, bringing in Altán, Encontrack and Total Play in Mexico, as well as Telefónica Costa Rica and the Instituto Costarricense de Electricidad. We attribute this success to our determination to diversify the client base, focusing primarily on mobile telephony operators but also seeking out opportunities with clients in other areas of business.
