New Accounting Guidance And Adoption Of New Accounting Guidance	2. New Accounting Guidance and Adoption of New Accounting Guidance *New Accounting Guidance* In December 2011, the FASB issued ASU No. 2011-11, "Disclosures about Offsetting Assets and Liabilities" ("ASU 2011-11"). ASU 2011-11 enhances disclosures regarding financial instruments and derivative instruments and requires companies to provide both net information and gross information for these assets and liabilities in order to enhance comparability between those companies that prepare their financial statements in accordance with GAAP and those companies that prepare their financial statements in accordance with International Financial Reporting Standards. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013 and interim periods within those annual periods. Since ASU 2011-11 requires only additional disclosures, the adoption of ASU 2011-11 will not affect the consolidated financial position, results of operations or cash flows of the Company. In June 2011, the FASB issued ASU 2011-05, "Presentation of Comprehensive Income" ("ASU 2011-05"). ASU 2011-05 requires companies to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The provisions of ASU 2011-05 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Since ASU 2011-05 amends the disclosure requirements concerning comprehensive income, the adoption of ASU 2011-05 will not affect the consolidated financial position, results of operations or cash flows of the Company. In December 2011, the FASB deferred indefinitely certain provisions of ASU 2011-05 that would require companies to present reclassification adjustments by component in both the statement where net income is presented and the statement where other comprehensive income is presented for both interim and annual financial statements. *Adoption of New Accounting Guidance* In September 2011, the FASB issued ASU 2011-08, "Testing Goodwill for Impairment" ("ASU 2011-08"). ASU 2011-08 allows a company to first assess qualitative factors to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent. The provisions of ASU 2011-08 are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 with early adoption permitted. The Company elected to adopt the provisions of ASU 2011-08 in 2011, which had no impact on the consolidated financial position, results of operations or cash flows of the Company. In January 2010, the FASB issued ASU 2010-06, "Fair Value Measurements and Disclosures" ("ASU 2010-06"). ASU 2010-06 requires companies to provide additional disclosures related to transfers in and out of Level 1 and Level 2 and in the reconciliation of Level 3 fair value measurements. ASU 2010-06 was effective for the Company for interim and annual reporting periods beginning in 2010, except for the disclosures related to the reconciliation of Level 3 fair value measurements, which was effective for the Company beginning in 2011. Since ASU 2010-06 requires only additional disclosures, the adoption of ASU 2010-06 did not affect the consolidated financial position, results of operations or cash flows of the Company. In October 2009, the FASB issued ASU 2009-13, "Revenue Recognition" ("ASU 2009-13"). ASU 2009-13 requires companies to allocate revenue in multiple-element arrangements based on an element's estimated selling price if vendor-specific or other third-party evidence of value is not available. ASU 2009-13 was effective for the Company beginning in 2011. The adoption of the provisions of ASU 2009-13 did not have a material effect on the consolidated financial position, results of operations or cash flows of the Company. In June 2009, the FASB issued authoritative accounting guidance ("Guidance") that in part, amends derecognition guidance for transfers of financial assets, eliminates the exemption from consolidation for qualifying special-purpose entities and requires additional disclosures. This Guidance was effective for the Company beginning in 2010. The adoption of the provisions of this Guidance did not have a material effect on the consolidated financial position, results of operations or cash flows of the Company. In June 2009, the FASB issued Guidance that amends the consolidation guidance applicable to variable interest entities. The provisions of this Guidance require entities to perform an analysis to determine whether the enterprise's variable interest or interests give it a controlling financial interest in a variable interest entity. The Guidance also requires an enterprise to assess on an ongoing basis to determine whether it is a primary beneficiary or has an implicit responsibility to ensure that a variable interest entity operates as designed. This Guidance was effective for the Company beginning in 2010. In January 2010, the FASB indefinitely deferred certain consolidation provisions of this Guidance. The adoption of the provisions of this Guidance did not have a material effect on the consolidated financial position, results of operations or cash flows of the Company.
