These changes require an enterprise to perform an analysis to determine whether the enterprises variable interest or interests give it a controlling financial interest in a variable interest entity; to require ongoing reassessments of whether an enterprise is the primary beneficiary of a variable interest entity; to eliminate the solely quantitative approach previously required for determining the primary beneficiary of a variable interest entity; to add an additional reconsideration event for determining whether an entity is a variable interest entity when any changes in facts and circumstances occur such that holders of the equity investment at risk, as a group, lose the power from voting rights or similar rights of those investments to direct the activities of the entity that most significantly impact the entitys economic performance; and to require enhanced disclosures that will provide users of financial statements with more transparent information about an enterprises involvement in a variable interest entity.  The adoption of these changes had no material impact on the Companys condensed consolidated financial statements.   Fair Value Measurements and Disclosures In January 2010, the FASB issued ASU 2010-06, an update to Topic 820, Fair Value Measurements and Disclosures.  ASU 2010-06 provides an update specifically to Subtopic 820-10 that requires new disclosures including, details of significant transfers in and out of Level 1 and Level 2 measurements and the reasons for the transfers and a gross presentation of activity within the Level 3 roll forward, presenting separately information about purchases, sales, issuances, and settlements.  ASU 2010-06 is effective for the first interim or annual reporting period beginning after December 15, 2009, except for the gross presentation of the Level 3 roll forward, which is required for interim and annual reporting periods beginning after December 15, 2010.  The adoption of ASU 2010-06 did not have a material impact on the Companys condensed consolidated financial statements.</td></tr></table> Note 15.  Recently Issued Accounting Standards   Consolidation of Variable Interest Entities On January 31, 2010, the Company adopted changes issued false false false us-types:textBlockItemType textblock Represents 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.
