Retail revenue

The Company produces and supplies water to end-users, including residential, commercial and governmental customers in the Cayman Islands under an exclusive retail license issued to Cayman Water by the Cayman Islands government to provide water in two of the three most populated and rapidly developing areas on Grand Cayman Island. Customers are billed on a monthly basis based on metered consumption and bills are typically collected within 30 to 35 days after the billing date. Receivables not collected within 45 days subject the customer to disconnection from water service. In 2019 and 2018, bad debts represented less than 1% of the Company’s total retail sales.

The Company recognizes revenue from water sales at the time water is supplied to the customer’s premises. The amount of water supplied is determined and invoiced based upon water meter readings performed at the end of each month. All retail water contracts are month-to-month contracts. The Company has elected the "right to invoice" practical expedient for revenue recognition on its retail water sale contracts and recognizes revenue in the amount to which the Company has a right to invoice.

Bulk revenue

The Company produces and supplies water to government-owned distributors in the Cayman Islands and The Bahamas.

OC-Cayman provides bulk water to the Water Authority-Cayman (“WAC”), a government-owned utility and regulatory agency, under various agreements. The WAC in turn distributes such water to properties in Grand Cayman outside of Cayman Water’s retail license area.

The Company sells bulk water in The Bahamas through its majority-owned subsidiary CW-Bahamas to the Water and Sewerage Corporation of The Bahamas (“WSC”), which distributes such water through its own pipeline system to residential, commercial and tourist properties on the Island of New Providence. The Company also sells water to a private resort on Bimini.

The Company has elected the “right to invoice” practical expedient for revenue recognition on its bulk water sale contracts and recognizes revenue in the amount to which the Company has a right to invoice.

Services and Manufacturing revenue

The Company, through its 51% owned subsidiary Aerex, is a custom and specialty manufacturer of water treatment-related systems and products and provides design, engineering, management, operating and other services applicable to commercial, municipal and industrial water production. Substantially all of Aerex’s customers are U.S. companies.

The Company also provides design, engineering and construction services for desalination projects through DesalCo, which is recognized by suppliers as an original equipment manufacturer of seawater reverse osmosis desalination plants. DesalCo also provides management and procurement services for desalination plants and engineering services relating to municipal water production, distribution and treatment.

The Company recognizes construction services and manufacturing revenue over time under the input method using costs incurred (which represents work performed) to date relative to total estimated costs at completion to measure progress toward satisfying its performance obligations as such measure best reflects the transfer of control of the promised good to the customer. Contract costs include labor, material and overhead. 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 this input 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.

The Company has elected the “right to invoice” practical expedient for revenue recognition on its management services agreements and recognizes revenue in the amount to which the Company has a right to invoice.

Practical Expedients and Exemptions

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for services performed.
