style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Intangibles - Goodwill and Other&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, requires us to test goodwill for impairment at least annually, or sooner, if facts or circumstances between scheduled annual tests indicate that it is more likely than not that the fair value of a reporting unit that has goodwill might be less than its carrying value. Currently our operating segments and reporting units are identical. We estimate the fair value of our reporting units by referring to the price that would be received to sell the unit as whole in an orderly transaction between market participants at the measurement date. For the goodwill assessment of our systems business, we believe that a typical market participant for the sale of our systems reporting unit would be a solar module manufacturer seeking to acquire a systems business with a large pipeline of utility-scale solar power plant projects, with the intent that these projects would provide a captive outlet for additional future solar module production. Therefore, we model the systems reporting unit's future performance for purposes of applying the income method of fair value measurement to include some of the profitability associated with the solar module element of the solar power plants that it builds and sells.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:26px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:25px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;We performed our goodwill impairment test in the fourth fiscal quarter of the year ended &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;December&amp;#160;31, 2010&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;  and determined that the fair value of our goodwill substantially exceeded the carrying value for each individual reporting unit. Therefore, we concluded that our goodwill was not impaired. We have also concluded that there have been no changes in facts and circumstances since the date of that test that would trigger an interim goodwill impairment test. &lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&amp;#160;&lt;/font&gt;&lt;/div&gt;&lt;/div&gt;</NonNumbericText><NonNumericTextHeader>5.

For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported.

May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss.
