FAIR VALUE OF FINANCIAL INSTRUMENTS [Abstract] |
Carrying Amount and Fair Value of Long-Term Debt | As of September 30, 2025 and December 31, 2024, all of the Company’s outstanding long-term debt interest rates were a fixed rate. The fair value of the Company’s long-term debt is determined by discounting their future cash flows using current market interest rates on similar instruments with comparable maturities consistent with ASC 825, Financial Instruments. Under the fair value hierarchy, the fair value of the long-term debt in the table below is classified as Level 2 measurements. Level 2 is valued using observable inputs other than quoted prices. The fair values for long-term debt differ from the carrying values primarily due to interest rates that differ from the current market interest rates. The carrying amount and fair value of Artesian Resources' long-term debt (including current portion) are shown below:
|  | September 30, 2025 |  |  | December 31, 2024 |
Carrying amount | $ | 176,885 |  | $ | 178,676 |
Estimated fair value |  | 157,065 |  |  | 154,795 |
