Summary of Significant Accounting Policies</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which we refer to as U.S. GAAP, and pursuant to the rules and regulations of the Securities and Exchange Commission, which we refer to as the SEC. The same accounting policies are followed for preparing the quarterly and annual financial information unless otherwise disclosed in the notes below. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The following accounting policies were adopted in the six months ended June 30, 2010: </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Consolidation — </i>In June and December 2009, the Financial Accounting Standards Board, which we refer to as the FASB, issued new accounting guidance that amends the consolidation guidance applicable to variable interest entities. The amendments affect the overall consolidation analysis under current accounting guidance. We adopted the new accounting guidance on January 1, 2010. The adoption of the new accounting guidance did not have a significant effect on our financial condition or results of operations. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     <i>Fair Value Measurements — </i>In January 2010, the FASB issued new accounting guidance that requires new disclosures related to fair value measurements. The new guidance requires separate disclosure for transfers between Levels 1 and 2 fair value hierarchies and the activities in the Level 3 reconciliation presented on a gross basis rather than as one net number for a particular line item. We adopted the new accounting guidance on January 1, 2010, except for the new disclosures related to Level 3 activities, which are effective for fiscal years and interim periods beginning after December 15, 2010. The new accounting guidance only amended the disclosure requirements related to fair value measurements; therefore the adoption did not have any impact on our financial condition or results of operations. </div> <div align="left" style="font-size: 10pt; margin-top: 12pt"><b><i>Recent Accounting Pronouncements</i></b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     In October 2009, the FASB issued new accounting guidance that amends the revenue recognition for multiple-element arrangements and expands the disclosure requirements related to such arrangements. The new guidance amends the criteria for separating consideration in multiple-deliverable arrangements, establishes a selling price hierarchy for determining the selling price of a deliverable, eliminates the residual method of allocation, and requires the application of relative selling price method in allocating the arrangement consideration to all deliverables. The new accounting guidance is effective for fiscal years beginning after June 15, 2010. We are currently evaluating the impact of the new guidance on our financial condition and results of operations. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock This element may be used to describe all significant accounting policies of the reporting entity.
