This update also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. This guidance is effective for interim and annual periods beginning after December 15, 2009, except for the requirement to disclose information about purchases, sales, issuances and settlements in the reconciliation of Level 3 measurements, which does not become effective until interim and annual periods beginning after December 15, 2010. As this guidance clarifies and provides for additional disclosure requirements only, the adoption of this guidance does not have an impact on the Company's results of operations, financial position or cash flows. Consolidation of Variable Interest Entities In June 2009, the FASB issued authoritative guidance that replaces the quantitative-based risk and rewards calculation for determining which reporting entity has a controlling financial interest in a variable interest entity with a qualitative approach. This revised guidance also requires additional disclosures about a reporting entity's involvement in variable interest entities. This guidance is effective for the Company beginning January 1, 2010. These changes did not have an impact on the Company's results of operations, financial position or cash flows; however, these changes could impact the accounting for the Company's interests in a variable interest entity in the future. </div> Note 2: New Accounting Pronouncements Fair Value Measurements In January 2010, the Financial Accounting Standards Board ("FASB") issued authoritative 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.
