Derivative Instruments and Hedging Activities

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

DPL previously entered into interest rate derivative contracts to manage interest rate exposure related to anticipated borrowings of fixed-rate debt. The derivative instruments were used for risk management purposes and were designated as cash flow hedges if they qualified under ASC 815 for accounting purposes. 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 on gains recognized in AOCL for the cash flow hedges for the periods indicated:
