7. | Derivatives and Hedging
The Company’s hedging and derivative policy allows management to enter into derivatives for the purpose of managing the commodity and financial market risks of its business operations, including the price of natural gas and the cost of borrowed funds. This policy specifically prohibits the use of derivatives for speculative purposes. The Company has five interest rate swaps associated with its variable rate debt as of December 31, 2023. Roanoke Gas has two variable-rate term notes in the amounts of $15 million and $10 million, with corresponding swap agreements to convert the variable interest rates into fixed rates of 2.00% and 2.49%, respectively. Midstream has three swap agreements corresponding to the variable rate term notes with original principal amounts of $14 million, $10 million, and $8 million. The swap agreements convert these three notes into fixed rate instruments with effective interest rates of 3.24%, 3.14%, and 2.443%, respectively. The swaps qualify as cash flow hedges with changes in fair value reported in other comprehensive income. No portion of the swaps were deemed ineffective during the periods presented. The fair value of the current and non-current portions of the interest rate swaps are reflected in the condensed consolidated balance sheets under the caption interest rate swaps. The table in Note 10 reflects the effect on income and other comprehensive income of the Company's cash flow hedges.
