We tested goodwill for impairment on an annual basis in April (through 2008), and more often if events or circumstances indicated there may have been impairment.  We historically (through the second quarter of 2009) had two reporting segments:  wholesale energy and retail energy.  Goodwill impairment testing was performed at the reporting unit level, which was consistent with our reporting segments.  We continually assessed whether any indicators of impairment existed, which required a significant amount of judgment.  Such indicators may have included a sustained significant decline in our share price and market capitalization; a decline in our expected future cash flows; a significant adverse change in legal factors or in the business climate; unanticipated competition; overall weaknesses in our industry; and slower growth rates.  Any adverse change in these factors could have had a significant impact on the recoverability of goodwill and could have had a material impact on our consolidated financial statements. During April 2008, we tested goodwill for impairment and determined that no impairments existed. During the third and fourth quarters of 2008, given adverse changes in the business climate and the credit markets, our market capitalization being lower than our book value during all of the fourth quarter and extending into 2009, our review of strategic alternatives to enhance stockholder value and reductions in our expected near-term cash flows from operations, we reviewed our goodwill for impairment.  We concluded that no goodwill impairments occurred as of September 30, 2008.  As discussed below, as of December 31, 2008, we concluded that our historical wholesale energy segment’s goodwill of $305 million was impaired. Goodwill was reviewed for impairments based on a twostep test.  In the first step, we compared the fair value of each reporting unit with its net book value.  We applied judgment in determining the fair value of our reporting units for purposes of performing our goodwill impairment tests because quoted market prices for our reporting units were not available.  In estimating the fair values of the reporting units, we used a combination of an income approach and a market-based approach. •       Income approach — We discounted the expected cash flows of each reporting unit.  The discount rate used represented the estimated weighted average cost of capital, which reflected the overall level of inherent risk involved in our operations and cash flows and the rate of return an outside investor would expect to earn.  To estimate cash flows beyond the final year of our model, we applied a terminal value multiple to the final year EBITDA. •       Market-based approach — We used the guideline public company method, which focused on comparing our risk profile and growth prospects to select reasonably similar/guideline publicly traded companies.  We also used a public transaction method, which focused on exchange prices in actual transactions as an indicator of fair value. In weighting the results of the various valuation approaches, prior to the fourth quarter of 2008, we placed more emphasis on the income approach, using management’s future cash flow projections for each reporting unit and riskadjusted discount rates.  As our earnings outlook declined, our earnings variability increased and our market capitalization declined significantly in 2008, we increased the weighting of the estimates of fair value of our reporting units determined by the marketbased approaches.  Further, the aggregate estimated fair value of our reporting units was compared to our total market capitalization, adjusted for a control premium.  A control premium was added to the market capitalization to reflect the value that existed with having control over an entire entity. If the estimated fair value of the reporting unit was higher than the recorded net book value, no impairment was considered to exist and no further testing was required.  However, if the estimated fair value of the reporting unit was below the recorded net book value, a second step must be performed to determine the goodwill impairment required, if any.  In the second step, the estimated fair value from the first step was used as the purchase price in a hypothetical acquisition of the reporting unit, which was then allocated to the reporting unit’s assets and liabilities in accordance with purchase accounting rules.  The residual amount of goodwill that resulted from this hypothetical purchase price allocation was compared to the recorded amount of goodwill for the reporting unit, and the recorded amount was written down to the hypothetical amount, if lower. Estimation of our Historical Wholesale Energy Reporting Unit’s Fair Value. We estimated the fair value of our wholesale energy reporting unit based on a number of subjective factors, including: (a) appropriate weighting of valuation approaches, as discussed above, (b) projections about the future power generation margins, (c) estimates of our future cost structure, (d) environmental assumptions, (e) riskadjusted discount rates for our estimated cash flows, (f) selection of peer group companies for the public company market approach, (g) required level of working capital, (h) assumed EBITDA multiple for terminal values and (i) time horizon of cash flow forecasts. As part of our process, we developed 15year forecasts of earnings and cash flows, assuming that demand for power grows at the rate of two percent a year.  We modeled all of our power generation facilities and those of others in the regions in which we operate, using these assumptions:  (a) the markets in which we operate will continue to be deregulated and earn a market return; (b) there will be a recovery in electricity margins over time such that companies building new generation facilities can earn a reasonable rate of return on their investment, which implies that margins and therefore cash flows in the future would be better than they are today because market prices will need to rise high enough to provide an incentive for new plants to be built, and the entire market will realize the benefit of those higher margins and (c) the long-term returns on future construction of new generation facilities will likely be driven by integrated utilities, which we expect will have a lower cost of capital than merchant generators, which implies that the revenues and margins described in (b) above will be at the level of return required for a regulated entity instead of a deregulated company.  We assumed that the aftertax rate of return on new construction was 7.5%.

We then performed the second step of the impairment test, which required an allocation of the fair value as the purchase price in a hypothetical acquisition of the reporting unit.  The significant hypothetical purchase price allocation adjustments made to the assets and liabilities of our wholesale energy reporting unit consisted of the following: •        Adjusting the carrying value of our property, plant and equipment to values that would be expected in the current credit and market environment •        Adjusting the carrying value of our emission allowances, which then traded at amounts significantly higher than our book value •        Adjusting the carrying value of our debt, which had a lower fair value than our book value <p class="MsoNormal" style="margin: 0in;
