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 Commonwealth of The Bahamas, the British Virgin Islands, the United States and Indonesia. 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 follows this method since it can make reasonably dependable estimates of the revenue and costs applicable to various stages of a contract. Under the percentage-of-completion method, the Company records revenue and recognizes profit or loss as work on the contract progresses. The Company estimates total project costs and profit to be earned on each long-term, fixed price contract prior to commencement of work on the contract and updates these estimates as work on the contract progresses. The cumulative amount of revenue recorded on a contract at a specified point in time is that percentage of total estimated revenue that incurred costs to date comprises of estimated total contract costs. If, as work progresses, the actual contract costs exceed estimates, the profit recognized on revenue from that contract decreases. The Company recognizes the full amount of any estimated loss on a contract at the time the estimates indicate such a loss. Any costs and estimated earnings in excess of billings are classified as current assets. Billings in excess of costs and estimated earnings on uncompleted contracts, if any, are classified as current liabilities.</div> <div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;FONT: 10pt Times New Roman, Times, Serif; MARGIN: 0pt 0px; TEXT-INDENT: 31.9pt; font-size-adjust: none; font-stretch: normal" align="justify"> </div> <div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;FONT: 10pt Times New Roman, Times, Serif; MARGIN: 0pt 0px; font-size-adjust: none; font-stretch: normal" align="justify">With respect to the plant construction contracts awarded as the result of a tender process, the Company assumes the risk that the costs associated with constructing the plant may be greater than it anticipated in preparing its bid, as the terms of such tender processes typically require the winner to guarantee the sales price for the plant at the bid amount. Because the Company bases its contracted sales price in part on its estimation of future construction costs, the profitability of its plant sales is dependent on its ability to estimate these costs accurately. The cost estimates the Company prepares in connection with the construction of plants to be sold to third parties are subject to inherent uncertainties. The cost of materials and construction may increase significantly after the Company submits its tender and accompanying bid price for a plant due to factors beyond the Company’s control, which could cause the profit margin for a plant to be less than the Company anticipated when the tender was submitted. The profit margin the Company initially expects to generate from a plant sale could be further affected by other factors, such as hydro-geologic conditions at the plant site that differ materially from those the Company believes exists, and therefore relies upon, in determining its bid price.</div> </div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table>
