New Accounting Pronouncements</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">In January 2010, the Financial Accounting Standards Board (“FASB”) issued additional authoritative guidance related to fair value measurements and disclosures. The guidance requires disclosure of details of significant transfers in and out of Level 1 and Level 2 fair value measurements. The guidance also clarifies the existing disclosure requirements for the level of disaggregation of fair value measurements and the disclosures on inputs and valuation techniques. The company adopted these provisions effective January 1, 2010. The adoption did not have a significant impact on our consolidated financial statements. In addition, the guidance also requires the presentation of purchases, sales, issuances and settlements within Level 3 on a gross basis rather than a net basis. We adopted this additional guidance pertaining to Level 3 fair value measurements effective January 1, 2011. The adoption of this guidance did not have any impact on our financial statements as it contains only disclosure requirements. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">In October 2009, the FASB issued new guidance regarding revenue arrangements with multiple deliverables. This new guidance requires companies to allocate revenue in arrangements involving multiple deliverables based on the estimated selling price of each deliverable, even though such deliverables are not sold separately either by the company or by other vendors. This new guidance is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. We adopted this pronouncement effective January 1, 2011. The adoption of this pronouncement did not have a significant impact on our financial statements. </div> </div>  <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringRepresents disclosure of any changes in an accounting principle, including a change from one generally accepted accounting principle to another generally accepted accounting principle when there are two or more generally accepted accounting principles that apply or when the accounting principle formerly used is no longer generally accepted.
