Foreign currency: The Company’s reporting currency is the United States dollar (“US$”). The functional currency of the Company and its foreign operating subsidiaries (other than NSC, AdR, and CW-Cooperatief) is the currency for each respective country. The functional currency for NSC, AdR, and CW-Cooperatief is the US$. 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.

Net foreign currency gains arising from transactions and re-measurements were $24,397 and $6,988 for the three months ended June 30, 2023 and 2022, respectively, and $50,176 and $29,034 for the six months ended June 30, 2023 and 2022, and are included in “Other income (expense) - Other” in the accompanying condensed consolidated statements of income.

Goodwill and intangible assets

Goodwill and intangible assets: Goodwill represents the excess cost of an acquired business over the fair value of the assets and liabilities of the acquired business as of the date of acquisition. Goodwill and intangible assets recorded as a result of a business combination and determined to have an indefinite useful life are not amortized but are tested for impairment annually or upon the identification of a triggering event. Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed periodically for impairment. The Company evaluates the possible impairment of goodwill annually as part of its reporting process for the fourth quarter of each fiscal year. Management identifies the Company’s reporting units for goodwill impairment testing purposes, which consist of Cayman Water, the bulk segment (which is comprised of CW-Bahamas and OC-Cayman), PERC, and the manufacturing segment (i.e., Aerex), and determines the carrying value of each reporting unit by assigning the assets and liabilities, including the existing goodwill and intangible assets, to those reporting units. The Company determines the fair value of each reporting unit and compares these fair values to the carrying amounts of the reporting units. To the extent the carrying amount of a reporting unit exceeds the fair value of the reporting unit, an impairment loss is recorded.

As of December 31, 2022, the Company elected to assess qualitative factors to determine whether it was necessary to perform the quantitative goodwill impairment testing conducted in prior years for all goodwill reporting units other than the manufacturing reporting unit. The Company assessed relevant events and circumstances to evaluate whether it is more likely than not that the fair values of such reporting units are less than their carrying values. The events and circumstances assessed for each unit included macroeconomic conditions, industry and market conditions, cost factors, overall financial performance, and other relevant events. Based upon this qualitative assessment the Company determined that it was more likely than not that the fair values of its Cayman Water and bulk segment reporting units exceeded their carrying values as of December 31, 2022. Based upon the Company’s negotiated, arms-length purchase of the remaining 39% equity interest in PERC from its minority shareholders for $7.8 million in January 2023, the fair value of the Company’s PERC reporting unit exceeded its carrying value by 79% as of December 31, 2022.

For the year ended December 31, 2022, the Company estimated the fair value of its manufacturing reporting unit by applying the discounted cash flow method, which relied upon seven-year discrete projections of operating results, working capital and capital expenditures, along with a terminal value subsequent to the discrete period. These seven-year projections were based upon historical and anticipated future results, general economic and market conditions, and considered the impact of planned business and operational strategies. The discount rates for the calculations represented the estimated cost of capital for market participants at the time of the analysis. The Company also estimated the fair value of its manufacturing reporting unit for the year ended December 31, 2022 by applying the guideline public company method. The Company weighted the fair values estimated for its manufacturing reporting unit under each method and summed such weighted fair values to estimate the overall fair value for the reporting unit. The respective weightings the

Company applied to each method for the year ended December 31, 2022 were 80% to the discounted cash flow method and 20% to the guideline public company method.

The fair value the Company estimated for its manufacturing reporting unit exceeded its carrying amount by 63% as of December 31, 2022.

The Company believes the inherent uncertainties associated with the accounting estimates and assumptions it uses for its estimates of its manufacturing reporting unit’s fair value have increased due to the current, less predictable economic conditions, which have resulted in increasing raw material prices, extended and unexpected delays in the procurement and delivery of its raw materials, and have also, the Company believes, adversely affected its customers. Should interest rates rise significantly in the future the Company would likely be required to increase the discount rate it uses under the discounted cash flow method to estimate the fair value of this reporting unit, and such increased discount rate in and of itself could decrease the estimated fair value of the manufacturing reporting unit under the discounted cash flow method.

As noted previously, based upon the Company’s estimation prepared as of December 31, 2022, the fair value of the Company’s manufacturing reporting unit exceeded its carrying value by 63%. However, if the Company determines in the future that Aerex’s discounted future cash inflows will be less than its present expectations, the Company may be required to record additional impairment losses to reduce the remaining carrying values of its manufacturing reporting unit’s goodwill and its remaining unamortized intangible assets balances, which amounted to $1,985,211 and $707,778, respectively, as of June 30, 2023. Any such impairment losses could have a material adverse impact on the Company’s consolidated results of operations.

Income taxes: The Company accounts for the income taxes arising from the operations of its United States subsidiaries under the asset and liability method. Deferred tax assets and liabilities, if any, are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided to the extent any deferred tax asset may not be realized.

The Company is not presently subject to income taxes in the other countries in which it operates.
