Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivatives and Hedging | 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 three interest rate swaps associated with its variable rate debt. Roanoke Gas has a swap agreement that effectively converts the $7,000,000 term note based on LIBOR into fixed-rate debt with a 2.30% effective interest rate. Midstream has two swap agreements corresponding to the $14,000,000 variable rate term note issued on June 12, 2019 and the $10,000,000 variable rate term note issued on June 13, 2019. The swap agreements convert these two notes into fixed rate instruments with effective interest rates of 3.24% and 3.14%, 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 Company had no outstanding derivative instruments for the purchase of natural gas. 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 8 reflects the effect on income and other comprehensive income of the Company's cash flow hedges.
