Duke Energy updates the test between annual tests if events or circumstances occur that would more likely than not reduce the fair value of a reporting unit below its carrying value. During the third quarter of 2009, in connection with the annual goodwill impairment test, Duke Energy recorded an approximate $371 million impairment charge to write-down the carrying value of Commercial Power's non-regulated Midwest generation reporting unit to its implied fair value. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">In the second quarter of 2010, based on circumstances discussed below, management determined that it was more likely than not that the fair value of Commercial Power's non-regulated Midwest generation reporting unit was below its respective carrying value. Accordingly, an interim impairment test was performed for this reporting unit. Determination of reporting unit fair value was based on a combination of the income approach, which estimates the fair value of Duke Energy's reporting units based on discounted future cash flows, and the market approach, which estimates the fair value of Duke Energy's reporting units based on market comparables within the utility and energy industries. Based on completion of step one of the second quarter 2010 impairment analysis, management determined that the fair value of Commercial Power's non-regulated Midwest generation reporting unit was less than its carrying value, which included goodwill of $500 million. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Commercial Power's non-regulated Midwest generation reporting unit includes nearly 4,000 MW of coal-fired generation capacity in Ohio dedicated to serve Ohio native load customers under the ESP through December 31, 2011. These assets also generate revenues through sales outside the native load customer base if circumstances arise that result in availability of excess capacity. Additionally, this reporting unit has approximately 3,600 MW of gas-fired generation capacity in Ohio, Pennsylvania, Illinois and Indiana which provides generation to unregulated energy markets in the Midwest. The businesses within Commercial Power's non-regulated generation reporting unit operate in market structures that are, for the most part, unregulated and allow for customer choice among suppliers. As a result, the operations within this reporting unit are subjected to competitive pressures that do not exist in any of Duke Energy's regulated jurisdictions. </font></p>

No impairment exists with respect to Commercial Power's wind generation assets. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">The fair value of the non-regulated Midwest generation reporting unit is impacted by a multitude of factors, including current and forecasted customer demand, forecasted power and commodity prices, uncertainty of environmental costs, competition, the cost of capital, valuation of peer companies and regulatory and legislative developments. Management's assumptions and views of these factors continually evolve, and certain views and assumptions used in determining the fair value of the reporting unit in the 2010 interim impairment test changed significantly from those used in the 2009 annual impairment test. These factors had a significant impact on the valuation of the non-regulated Midwest generation reporting unit.

<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><b>Duke Energy Ohio. </b>For the same reasons discussed above, during the third quarter of 2009, in connection with the annual goodwill impairment test, Duke Energy Ohio recorded an approximate $727 million goodwill impairment charge to write-down the carrying value of Duke Energy Ohio's non-regulated Midwest generation reporting unit to its implied fair value. In the second quarter of 2010 management determined that is was more likely than not that the fair value of Duke Energy Ohio's non-regulated Midwest generation reporting unit was less than its carrying value. Accordingly, Duke Energy Ohio also impaired its entire goodwill balance of $461 million related to this reporting unit during the second quarter of 2010. Also, as discussed above, Duke Energy Ohio recorded $160 million of pre-tax impairment charges related to certain generating assets and emission allowances primarily associated with these generation assets in the Midwest to write-down the value of these assets to their estimated fair value. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">In the second quarter of 2010, goodwill for Ohio T&D was also analyzed. The fair value of the Ohio T&D reporting unit is impacted by a multitude of factors, including current and forecasted customer demand, discount rates, valuation of peer companies, and regulatory and legislative developments. Management periodically updates the load forecasts to reflect current trends and expectations based on the current environment and future assumptions. The spring and summer 2010 load forecast indicated that load will not return to 2007 weather-normalized levels for several more years. Based on the results of the second quarter 2010 impairment analysis, the fair value of the Ohio T&D reporting unit was $216 million below its book value at Duke Energy Ohio and $40 million higher than its book value at Duke Energy. Accordingly, this goodwill impairment charge was only recorded by Duke Energy Ohio. </font></p>

<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><b>Duke Energy.</b> Duke Energy is required to perform an annual goodwill impairment test as of the same date each year and, accordingly, performs its annual impairment testing of goodwill as of August 31. Duke Energy updates the test between annual tests if events or circumstances occur that would more likely than not reduce the fair value of a reporting unit below its carrying value. During the third quarter of 2009, in connection with the annual goodwill impairment test, Duke Energy recorded an approximate $371 million impairment charge to write-down the carrying value of Commercial Power's non-regulated Midwest generation reporting unit to its implied fair value. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">In the second quarter of 2010, based on circumstances discussed below, management determined that it was more likely than not that the fair value of Commercial Power's non-regulated Midwest generation reporting unit was below its respective carrying value. Accordingly, an interim impairment test was performed for this reporting unit. Determination of reporting unit fair value was based on a combination of the income approach, which estimates the fair value of Duke Energy's reporting units based on discounted future cash flows, and the market approach, which estimates the fair value of Duke Energy's reporting units based on market comparables within the utility and energy industries. Based on completion of step one of the second quarter 2010 impairment analysis, management determined that the fair value of Commercial Power's non-regulated Midwest generation reporting unit was less than its carrying value, which included goodwill of $500 million. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Commercial Power's non-regulated Midwest generation reporting unit includes nearly 4,000 MW of coal-fired generation capacity in Ohio dedicated to serve Ohio native load customers under the ESP through December 31, 2011. These assets also generate revenues through sales outside the native load customer base if circumstances arise that result in availability of excess capacity. Additionally, this reporting unit has approximately 3,600 MW of gas-fired generation capacity in Ohio, Pennsylvania, Illinois and Indiana which provides generation to unregulated energy markets in the Midwest. The businesses within Commercial Power's non-regulated generation reporting unit operate in market structures that are, for the most part, unregulated and allow for customer choice among suppliers. As a result, the operations within this reporting unit are subjected to competitive pressures that do not exist in any of Duke Energy's regulated jurisdictions. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Commercial Power's other businesses, including the wind generation assets, are in a separate reporting unit for goodwill impairment testing purposes. No impairment exists with respect to Commercial Power's wind generation assets. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">The fair value of the non-regulated Midwest generation reporting unit is impacted by a multitude of factors, including current and forecasted customer demand, forecasted power and commodity prices, uncertainty of environmental costs, competition, the cost of capital, valuation of peer companies and regulatory and legislative developments. Management's assumptions and views of these factors continually evolve, and certain views and assumptions used in determining the fair value of the reporting unit in the 2010 interim impairment test changed significantly from those used in the 2009 annual impairment test.

These rates are currently above market prices for generation services, resulting in customers switching to other generation providers. Duke Energy Ohio will reset its standard service offer for native load customers for generation effective January 1, 2012, and is presently evaluating a number of alternative structures. Given forward power prices, which have declined from the time of the 2009 impairment, it is likely that the generation margin earned in 2012-2015 will be lower than present levels.</font></p></td></tr></table></td></tr></table>

In the second quarter of 2010 management determined that is was more likely than not that the fair value of Duke Energy Ohio's non-regulated Midwest generation reporting unit was less than its carrying value. Accordingly, Duke Energy Ohio also impaired its entire goodwill balance of $461 million related to this reporting unit during the second quarter of 2010. Also, as discussed above, Duke Energy Ohio recorded $160 million of pre-tax impairment charges related to certain generating assets and emission allowances primarily associated with these generation assets in the Midwest to write-down the value of these assets to their estimated fair value. </font></p>

The fair value of the Ohio T&D reporting unit is impacted by a multitude of factors, including current and forecasted customer demand, discount rates, valuation of peer companies, and regulatory and legislative developments. Management periodically updates the load forecasts to reflect current trends and expectations based on the current environment and future assumptions. The spring and summer 2010 load forecast indicated that load will not return to 2007 weather-normalized levels for several more years. Based on the results of the second quarter 2010 impairment analysis, the fair value of the Ohio T&D reporting unit was $216 million below its book value at Duke Energy Ohio and $40 million higher than its book value at Duke Energy. Accordingly, this goodwill impairment charge was only recorded by Duke Energy Ohio. </font></p>

<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><b>Duke Energy.</b> Duke Energy is required to perform an annual goodwill impairment test as of the same date each year and, accordingly, performs its annual impairment testing of goodwill as of August 31. Duke Energy updates the test between annual tests if events or circumstances occur that would more likely than not reduce the fair value of a reporting unit below its carrying value. During the third quarter of 2009, in connection with the annual goodwill impairment test, Duke Energy recorded an approximate $371 million impairment charge to write-down the carrying value of Commercial Power's non-regulated Midwest generation reporting unit to its implied fair value. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">In the second quarter of 2010, based on circumstances discussed below, management determined that it was more likely than not that the fair value of Commercial Power's non-regulated Midwest generation reporting unit was below its respective carrying value. Accordingly, an interim impairment test was performed for this reporting unit. Determination of reporting unit fair value was based on a combination of the income approach, which estimates the fair value of Duke Energy's reporting units based on discounted future cash flows, and the market approach, which estimates the fair value of Duke Energy's reporting units based on market comparables within the utility and energy industries. Based on completion of step one of the second quarter 2010 impairment analysis, management determined that the fair value of Commercial Power's non-regulated Midwest generation reporting unit was less than its carrying value, which included goodwill of $500 million. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Commercial Power's non-regulated Midwest generation reporting unit includes nearly 4,000 MW of coal-fired generation capacity in Ohio dedicated to serve Ohio native load customers under the ESP through December 31, 2011. These assets also generate revenues through sales outside the native load customer base if circumstances arise that result in availability of excess capacity. Additionally, this reporting unit has approximately 3,600 MW of gas-fired generation capacity in Ohio, Pennsylvania, Illinois and Indiana which provides generation to unregulated energy markets in the Midwest. The businesses within Commercial Power's non-regulated generation reporting unit operate in market structures that are, for the most part, unregulated and allow for customer choice among suppliers. As a result, the operations within this reporting unit are subjected to competitive pressures that do not exist in any of Duke Energy's regulated jurisdictions. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Commercial Power's other businesses, including the wind generation assets, are in a separate reporting unit for goodwill impairment testing purposes. No impairment exists with respect to Commercial Power's wind generation assets. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">The fair value of the non-regulated Midwest generation reporting unit is impacted by a multitude of factors, including current and forecasted customer demand, forecasted power and commodity prices, uncertainty of environmental costs, competition, the cost of capital, valuation of peer companies and regulatory and legislative developments. Management's assumptions and views of these factors continually evolve, and certain views and assumptions used in determining the fair value of the reporting unit in the 2010 interim impairment test changed significantly from those used in the 2009 annual impairment test. These factors had a significant impact on the valuation of the non-regulated Midwest generation reporting unit. More specifically, the following factors significantly impacted management's valuation of the reporting unit: </font></p>

Duke Energy Ohio will reset its standard service offer for native load customers for generation effective January 1, 2012, and is presently evaluating a number of alternative structures.
