The Company enters into interest rate swaps to hedge interest rate risk. These arrangements include hedges of individual fixed rate commercial loans and also hedges of a specified portion of pools of prepayable fixed rate mortgage loans under the "last of layer" method. These relationships qualify as fair value hedges under FASB ASC 815, Derivatives and Hedging ("ASC 815"), which provides for offsetting of the recognition of gains and losses of the respective interest rate swap and the hedged items. Gains and losses on interest rate swaps designated in these hedge relationships, along with the offsetting gains and losses on the hedged items attributable to the hedged risk, are recognized in current earnings within the same income statement line item.

Upon electing to apply ASC 815 fair value hedge accounting, the carrying value of the hedged items are adjusted to reflect the cumulative impact of changes in fair value attributable to the hedged risk. The hedge basis adjustment remains with each hedged item until the hedged item is de-recognized from the balance sheet. The following tables presents the impact of fair value hedge accounting on the carrying value of the hedged items at September 30, 2023 and September 30, 2022.

At September 30, 2023, the amortized cost basis of the closed loan portfolios used in the hedging relationships was $1,780,503,000, the cumulative basis adjustment associated with the hedging relationships was $(45,622,000), and the amount of the designated hedged items was $670,000,000.

The Company has entered into interest rate swaps to convert certain short-term borrowings to fixed rate payments. The primary purpose of these hedges is to mitigate the risk of changes in future cash flows resulting from increasing interest rates. For qualifying cash flow hedges under ASC 815, gains and losses on the interest rate swaps are recorded in accumulated other comprehensive income ("AOCI") and then reclassified into earnings in the same period the hedged cash flows affect earnings and within the same
income statement line item as the hedged cash flows. As of September 30, 2023, the maturities for hedges of adjustable rate borrowings ranged from less than one year to seven years, with the weighted average being 5.5 years.

The Company periodically enters into certain interest rate swap agreements in order to provide commercial loan customers the ability to convert from variable to fixed interest rate payments, while the Company retains a variable rate loan. Under these agreements, the Company enters into a variable rate loan agreement and a swap agreement with the client. The swap agreement effectively converts the client’s variable rate loan into a fixed rate. The Company enters into a corresponding swap agreement with a third party in order to offset its exposure on the variable and fixed components of the client's swap agreement. The interest rate swaps are derivatives under ASC 815, with changes in fair value recorded in earnings. The net impact to the statement of operations for the year ended September 30, 2023 was a decrease in other income of $870,000. There was no net income to the statement of operations for the year ended September 30, 2022 as the changes in fair value of the receive fixed swap and pay fixed swap offset each other. As of September 30, 2023, none of the outstanding notional balance is associated with related party loans.
