Under this IRSA, we have changed the variable-rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the IRSA, we pay a fixed contractual interest rate and (i) make an additional payment if the London Interbank Offering Rate (LIBOR) variable rate payment is below a contractual rate or (ii) receive a payment if the LIBOR variable rate payment is above the contractual rate. On August 29, 2019, we entered into a second IRSA with CoBank covering an additional $42,000,000 of our aggregate indebtedness to CoBank on August 29, 2019.

Under this IRSA, we have changed the variable rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the IRSA, we pay a fixed contractual interest rate and (i) make an additional payment if the LIBOR variable rate payment is below a contractual rate or (ii) receive a payment if the LIBOR variable rate payment is above the contractual rate. Each month, we make interest payments to CoBank under its loan agreements based on the current applicable LIBOR Rate plus the contractual LIBOR margin then in effect with respect to the loan, without reflecting our IRSAs. At the end of each calendar month, CoBank adjusts our aggregate interest payments based on the difference, if any, between the amounts paid by us during the month and the current effective interest rate. Net interest payments are reported in our consolidated income statement as interest expense. Our IRSAs under our credit facilities both qualify as cash flow hedges for accounting purposes under GAAP. We reflect the effect of these hedging transactions in the financial statements. The unrealized gain/loss is reported in other comprehensive income. If we terminate our IRSAs, the cumulative change in fair value at the date of termination would be reclassified from accumulated other comprehensive income, which is classified in stockholders’ equity, into earnings on the consolidated statements of income. The fair value of the Company’s IRSAs were determined based on valuations received from CoBank and were based on the present value of expected future cash flows using discount rates appropriate with the terms of the IRSAs.

On June 30, 2022, the fair value of these swaps was $1,590,396, which has been recorded net of deferred tax of $453,899, resulting in the $1,136,497 in accumulated other comprehensive income. On June 30, 2021, the fair value liability of these swaps was $1,728,727, which has been recorded net of deferred tax benefit of $493,379, resulting in the $1,235,348 in accumulated other comprehensive loss.
