7.  Fair Value of Financial Instruments

The accounting standards regarding fair value measurements establish a fair value hierarchy which indicates the extent to which inputs used in measuring fair value are observable in the market.  Level 1 inputs include quoted prices for identical instruments and are the most observable.  Level 2 inputs include quoted prices for similar assets and observable inputs such as interest rates, commodity rates and yield curves.  Level 3 inputs are not observable in the market and include management’s own judgments about the assumptions market participants would use in pricing the asset or liability.

The Company has recorded its interest rate swap liability at fair value in accordance with the standards.  The liability is recorded under the caption “Other deferred credits” on the balance sheets.  The table below illustrates the fair value of the interest rate swap as of the end of the reporting period.

Fair values are measured as the present value of all expected future cash flows based on the swap yield curve as of the date of the valuation.  These inputs to this calculation are deemed to be Level 2 inputs.  The balance sheet carrying value reflects the Company’s credit quality as of December 31, 2025.  The rate used in discounting all prospective cash flows anticipated to be made under this swap reflects a representation of the yield to maturity for 30-year debt on utilities rated A- as of December 31, 2025.  The use of the Company’s credit quality resulted in a reduction in the swap liability of $10 as of December 31, 2025.  The fair value of the swap reflecting the Company’s credit quality as of December 31, 2024 is shown in the table below.

The carrying amount of current assets and liabilities that are considered financial instruments approximates fair value as of the dates presented.  The Company’s total long-term debt, with a carrying value of $224,660 at December 31, 2025, and $208,178 at December 31, 2024, had an estimated fair value of approximately $207,000 and $189,000, respectively.  The estimated fair value of debt was calculated using a discounted cash flow technique that incorporates a market interest yield curve with adjustments for duration and risk profile.  These inputs to this calculation are deemed to be Level 2 inputs.  The Company recognized its credit rating in determining the yield curve and did not factor in third party credit enhancements including the letter of credit on the 2008 PEDFA Series A issue.

Customers’ advances for construction and note receivable have carrying values at December 31, 2025 of $22,357 and $255, respectively.  At December 31, 2024, customers’ advances for construction and note receivable had carrying values of $20,546 and $255, respectively.  The relative fair values of these amounts cannot be accurately estimated since the timing of future payment streams is dependent upon several factors, including new customer connections, customer consumption levels and future rate increases.

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
