X
- Definition The amount reclassified from regulatory assets to interest expense during the period as a result of interest rate swap settlements. The Company uses regulatory accounting treatment rather than hedge accounting to defer the unrealized gains and losses on its interest rate swap. Instead of the effective portion being recorded as other comprehensive income or loss and the ineffective portion being recognized in earnings using the cash flow hedge accounting rules provided by the derivative accounting standards, the entire unrealized swap value is recorded as a regulatory asset. Based on current ratemaking treatment, the Company expects the unrealized gains and losses to be recognized in rates as a component of interest expense as the swap settlements occur. Swap settlements are recorded in the income statement with the hedged item as interest expense. + References No definition available. + Details
