REGULATORY LIABILITIES [Abstract] |
REGULATORY LIABILITIES | NOTE 12 – REGULATORY LIABILITIES ASC 980, Regulated Operations, stipulates generally accepted accounting principles for companies whose rates are established or subject to approvals by a third-party regulatory agency. Certain obligations are deferred and/or amortized as determined by the DEPSC, MDPSC, and PAPUC. Regulatory liabilities represent excess recovery of cost or other items that have been deferred because it is probable such amounts will be returned to customers through future regulated rates. Utility plant retirement cost obligation consists of estimated costs related to the potential removal and replacement of facilities and equipment on the Company’s water and wastewater properties. As authorized by the DEPSC, when depreciable units of utility plant are retired, any cost associated with retirement, less any salvage value or proceeds received, is charged to a regulated retirement liability. The annual amortization currently authorized by the DEPSC could be adjusted in future rate applications. Deferred settlement refunds consist of reimbursements from the Trust for Artesian Water’s past capital and operating costs, totaling approximately $10.0 million, related to the treatment costs associated with the release of contaminants from the Site in groundwater that Artesian Water uses for public potable water supply, pursuant to the Settlement Agreement. The full amount of $10.0 million has been paid to us, in four installments of approximately $2.5 million each, in August 2022, July 2023, July 2024 and July 2025. Artesian Water received approval from the DEPSC in October 2022 to refund to its customers these reimbursements for past capital and operating costs. The refund for the reimbursements was applied to customer bills in annual installments. The refunds occurred in October 2022, August 2023, August 2024 and August 2025. The amount of the credit was calculated by dividing the amount of the reimbursement by the number of eligible customers. Beginning in 2022, Artesian Water began recording recovery of capital expenditures related to treatment of contaminants from the Site as Contributions in Aid of Construction and began recording expense recovery as an offset to operations and maintenance expense, with the intention that those recoveries will be available for inclusion and consideration in any future rate applications. Pursuant to the enactment of the Tax Cuts and Jobs Act, or TCJA, on December 22, 2017, the Company adjusted its existing deferred income tax balances to reflect the decrease in the corporate income tax rate from 34% to 21% (see Note 7 – Income Taxes) resulting in a decrease in the net deferred income tax liability of $24.3 million, of which $22.8 million was reclassified to a regulatory liability related to Artesian Water and Artesian Water Maryland. The regulatory liability amount is subject to certain Internal Revenue Service, or IRS, normalization rules that require the benefits to customers be spread over the remaining useful life of the underlying assets giving rise to the associated deferred income taxes. On January 31, 2019, the DEPSC approved Artesian Water to amortize the regulatory liability amount of $22.2 million over a period of 49.5 years beginning February 1, 2018, subject to audit at a later date. In May 2022, Artesian Water received a rate order from the DEPSC instructing Artesian Water to continue amortizing the liability over a period of 49.5 years, subject to review in Artesian Water’s next base rate filing. On June 12, 2024, the DEPSC approved a settlement agreement for the Artesian Water rate application, filed on April 28, 2023, that required two changes to the deferred income tax regulatory liability effective June 12, 2024. A $7.6 million gross-up adjustment was recorded to reflect the benefit customers would receive from the implementation of new base rates and $4.0 million of the regulatory liability, which represents costs not subject to IRS normalization rules, is now required to be amortized over a six-year period rather than 49.5 years. The MDPSC has not issued a final order on the regulatory liability amount of $0.6 million regarding the effects of the TCJA on Maryland customers. Regulatory liabilities comprise:
