We have included the financial results of Ray Tracker in our condensed consolidated financial statements from the date of acquisition. We concluded that the impact of this acquisition was not material to our consolidated balance sheets and results of operations.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;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:left;text-indent:26px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-weight:bold;"&gt;Fiscal 2010 Acquisition&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;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:left;text-indent:26px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;NextLight Renewable Power&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;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:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;On &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;July&amp;#160;12, 2010&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, we completed the acquisition of NextLight Renewable Power, LLC (NextLight), a leading developer of utility-scale solar power projects in the southwestern United States. NextLight was formed by a private equity firm focused on investing in North America's energy infrastructure. This transaction expanded our pipeline of solar power projects in the southwestern United States and supports our expansion in the U.S. utility-scale power market. We have integrated NextLight into our systems business, which provides a complete PV solar power solution, including project development, EPC services, O&amp;amp;M services, when applicable, and project finance, when required.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:24px;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:26px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The total consideration for this acquisition was &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$296.7 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; in an all-cash transaction. In allocating the purchase price based on estimated fair values, we recorded approximately &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$146.8 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; of goodwill, &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$2.5 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; of net tangible assets, and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$147.4 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; of project assets. We have included the financial results of NextLight in our condensed consolidated financial statements beginning on the acquisition date. For the period from January 1, 2010 to March 27, 2010, NextLight did not recognize any revenue and did not incur a material net loss. Therefore, had the acquisition of NextLight occurred on December 27, 2009 (the first day of our fiscal year 2010), our reported net sales would not have changed and our reported net income would not have materially changed from the amounts previously reported.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:24px;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>4.
