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, and provides water-related products and services, to its customers in the Cayman Islands, Belize, The Bahamas, the British Virgin Islands, Indonesia and the United States. The Company sells water to a variety of customers, including public utilities, commercial and tourist properties, residential properties and government facilities. The base price of water supplied by the Company, and adjustments thereto, are determined by the terms of a retail license and 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 manufactures and services a wide range of products and provides design, engineering, management, operating and other services applicable to commercial and municipal water production, supply and treatment, and industrial water and wastewater treatment.
