GOODWILL AND OTHER INTANGIBLE ASSETS The accounting guidance for goodwill requires that goodwill be evaluated for impairment at the reporting unit level. A reporting unit is an operating segment, as defined by the segment reporting accounting guidance, or a component or combination of components within an operating segment with similar economic characteristics that are one level below an operating segment. Generally, each AES business constitutes a reporting unit. In the event that more than one reporting unit is acquired in a single acquisition, goodwill is assigned to the reporting units that benefit from the goodwill on a relative fair value basis. The following table summarizes the changes in the carrying amount of goodwill, by segment as of December 31, 2009, 2008 and 2007. There was no goodwill associated with our North America—Utilities segment during the years ended December 31, 2009, 2008 and 2007.   <table border="0" cellspacing="0" cellpadding="0" width="100%"

The fair value of the reporting units was determined using the income approach based on a discounted cash flow valuation model as current quoted market prices were not always available. In 2009, Kilroot, our subsidiary in the United Kingdom, reported in the Europe Generation segment, incurred goodwill impairment loss of $118 million. Kilroot is a generation plant fired primarily by coal. Factors contributing to the impairment included: reduced profit expectations based on latest estimates of future commodity prices and reduced expectations on the recovery of cash flows on the existing plant following the Company’s decision to forgo capital expenditures to meet emission allowance requirements taking effect in 2024. Additionally, one of our subsidiaries located in the Ukraine and reported within “Corporate and Other” incurred a goodwill impairment loss of $4 million. For the years ended December 31, 2008 and 2007, the Company had no goodwill impairment.
