Certain information and note disclosures normally included in annual financial statements prepared in accordance with US GAAP have been condensed or omitted in these condensed financial statements pursuant to SEC rules and regulations, although the Company believes that the disclosures made herein are adequate to make the information not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

The functional currency of the Company and its foreign operating subsidiaries (other than NSC, AdR, and CW-Cooperatief) is the currency for each respective country. The functional currency for NSC, AdR, and CW-Cooperatief is the US$. NSC and AdR conduct business in US$ and Mexican pesos and CW-Cooperatief conducts business in US$ and euros. The exchange rates for the Cayman Islands dollar and the Bahamian dollar are fixed to the US$. The exchange rates for conversion of Mexican pesos and euros into US$ vary based upon market conditions.

Revenue recognition: Revenue is recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

The following table presents the Company’s revenue disaggregated by revenue source (unaudited).

	Three Months Ended March 31,
	2021		2020
Retail revenue	$	5,711,305	$	7,257,432
Bulk revenue		6,245,970		6,440,284
Services revenue		3,540,846		3,114,813
Manufacturing revenue		1,605,196		3,913,192
Total revenue	$	17,103,317	$	20,725,721

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 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 2021 and 2020, 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 two 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, under two agreements with 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. CW-Bahamas also sold water to a private resort on Bimini through December 18, 2020, which generated revenue of approximately $127,000 for the year ended December 31, 2020.

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 provides design, engineering, management, procurement and construction services for desalination infrastructure through DesalCo, which serves customers in the Cayman Islands, The Bahamas and the British Virgin Islands.

The Company also develops, builds, sells, operates and manages water, wastewater and water reuse infrastructure through PERC. All of PERC's customers are companies or governmental entities located in the U.S.

The Company, through Aerex, is a custom and specialty manufacturer of water treatment-related systems and products applicable to commercial, municipal and industrial water production. Substantially all of Aerex’s customers are U.S. companies.

The Company generates services revenue from DesalCo and PERC and generates manufacturing revenue from Aerex.

The Company recognizes revenue for its construction and specialized/custom manufacturing contracts 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 amounts payable to subcontractors. The Company follows this method since it can make reasonably dependable estimates of the revenue and costs applicable to the 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 contract assets are classified as current assets. Contract liabilities 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 services agreements and recognizes revenue in the amount to which the Company has a right to invoice.

Revenue recognized and amounts billed on contracts in progress are summarized as follows:

	March 31, 2021		December 31, 2020
Revenue recognized to date on contracts in progress	$	8,186,878	$	17,534,449
Amounts billed to date on contracts in progress		(7,977,023)		(17,791,928)
Retainage		414,011		312,130
Net contract asset	$	623,866	$	54,651

The above net balances are reflected in the accompanying condensed consolidated balance sheet as follows:

	March 31, 2021		December 31, 2020
Contract assets	$	669,419	$	516,521
Contract liabilities		(45,553)		(461,870)
Net contract asset	$	623,866	$	54,651

As of March 31, 2021, the Company had unsatisfied or partially unsatisfied performance obligations for contracts in progress representing approximately $1.4 million in aggregate transaction price for contracts with an original expected length of greater than one year. The Company expects to earn revenue as it satisfies its performance obligations under

those contracts in the amount of approximately $1.0 million during the remainder of the year ending December 31, 2021 and approximately $0.4 million thereafter.

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.

Comparative amounts: Certain amounts presented in the financial statements previously issued for 2020 have been reclassified to conform to the current periods’ presentation.
