Cash Flow Hedges
DPL previously used derivative financial instruments primarily to manage the interest rate risk associated with our long-term debt. These interest rate derivative contracts were settled in 2013, and we continue to amortize amounts out of AOCL into interest expense.

The following tables provide information concerning gains recognized in AOCI for the cash flow hedges for the three and nine months ended September 30, 2026 and 2025:
