1. Principal activity

Consolidated Water Co. Ltd., and its subsidiaries (collectively, the “Company”) use reverse osmosis technology to produce potable water from seawater. The Company processes and supplies water to its customers in the Cayman Islands, Belize and the Bahamas. The Company sells water to a variety of customers, including public utilities, commercial and tourist properties, residential properties and government utilities. The base prices of water supplied by the Company, and adjustments thereto, are determined by the terms of the Company’s retail license and its bulk water supply contracts, which provide for adjustments based upon the movement in the government price indices specified in the license and contracts, as well as monthly adjustments for changes in the cost of energy. The Company also provides engineering, design and construction services for water plants, and manages and operates water plants owned by others.
