Financial instruments	17. Financial instruments Credit risk: The Company is not exposed to significant credit risk on its retail customer accounts as its policy is to cease supply of water to customers’ accounts that are more than 45 days overdue. The Company’s exposure to credit risk is concentrated on receivables from its bulk water, services, and manufacturing customers. The Company considers these receivables fully collectible and therefore has not recorded a material allowance for these receivables. Interest rate risk: The Company is not subject to significant interest rate risk arising from fluctuations in interest rates. Foreign exchange risk: All relevant foreign currencies other than the Mexican peso and the euro have been fixed to the dollar for more than 50 years and as a result, the Company does not employ a hedging strategy against exchange rate risk associated with the reporting in dollars. If any of these fixed exchange rates become a floating exchange rate or if any of the foreign currencies in which the Company conducts business depreciate significantly against the dollar, the Company’s consolidated results of operations could be adversely affected. Fair values: As of December 31, 2025 and 2024, the carrying amounts of cash equivalents, accounts receivable, accounts payable, accrued expenses, accrued compensation, dividends payable and other current liabilities approximate their fair values due to the short-term maturities of these instruments. As of December 31, 2025 and 2024, the Company does not have assets and liabilities measured at fair value to present in the fair value hierarchy.
