The amount of interest rate hedges included in unrealized gains on cash flow hedges, net of tax, at September 30, 2009 was a loss of $2 million.         Unrealized gains on commodity hedges included those related to Midwest Generation and EME Homer City futures and forward electricity contracts that qualify for hedge accounting. These gains arise because current forecasts of future electricity prices in these markets are lower than the contract prices. As EME's hedged positions for continuing operations are realized, $146 million, after tax, of the net unrealized gains on cash flow hedges at September 30, 2009 are expected to be reclassified into earnings during the next 12 months. Management expects that reclassification of net unrealized gains will increase energy revenue recognized at market prices. Actual amounts ultimately reclassified into earnings over the next 12 months could vary materially from this estimated amount as a result of changes in market conditions. The maximum period over which a cash flow hedge is designated is through December 31, 2011.</td></tr></table> Note 4.
