New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2010, the FASB issued Accounting Standards Update (ASU) No. 2010-06, “Fair Value Measurements and Disclosures (ASC Topic 820) – Improving Disclosures About Fair Value Measurements.” This amendment requires separate disclosures about purchases, sales, issuances and settlements relating to Level 3 measurements. The new disclosures are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. We adopted this standard in the first quarter of 2012. Other than requiring additional disclosures, the adoption of this new guidance did not have a material impact on our consolidated financial statements. In December 2010, the FASB issued ASU No. 2010-28, “Intangibles - Goodwill and Other (ASC Topic 350) – When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts.” This amendment modifies the criteria for performing Step 2 of the goodwill impairment test for reporting units with zero or negative carrying amounts, and it requires performing Step 2 if qualitative factors indicate that it is more likely than not that an impairment exists. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. Any goodwill impairment resulting from the initial adoption of the amendments should be recorded as a cumulative effect adjustment to beginning retained earnings. Any goodwill impairments occurring after the initial adoption of the amendments should be included in earnings. We adopted this standard in the first quarter of 2012. The adoption of this new guidance did not have a material impact on our financial statements. In December 2010, the FASB issued ASU No. 2010-29, “Business Combinations (ASC Topic 805) – Disclosure of Supplementary Pro Forma Information for Business Combinations.” This amendment expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. This amendment is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. Early adoption is permitted. We adopted this standard in the first quarter of 2012. Other than requiring additional disclosures, the adoption of this amendment did not have a material impact on our consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement (Topic 820) – Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS.” The amendments provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. The amendments also change certain fair value measurement principles and enhance the disclosure requirements, particularly for Level 3 fair value measurements. The amendments are effective during interim and annual periods beginning after December 15, 2011 and should be applied prospectively. Early adoption is not permitted. We adopted this standard during the second quarter of 2012. Other than requiring additional disclosures, the adoption of this amendment did not have a material impact on our consolidated financial statements. In July 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220) – Presentation of Comprehensive Income.” The amendment eliminates the option to present other comprehensive income and its components in the statement of stockholders’ equity. The amendment requires all nonowner changes in stockholders’ equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendment, which must be applied retrospectively, is effective for interim and annual periods beginning after December 15, 2011, with early adoption permitted. We adopted this standard during the second quarter of 2012. Other than requiring a change in the format of our financial statement presentation, the adoption of this amendment did not have a material impact on our consolidated financial statements. In December 2011, the FASB issued ASU No. 2011-12, “Comprehensive Income (Topic 220) – Deferral of the Effective Date for Amendments of 2011-05.” The amendment allows entities to continue to report reclassifications out of accumulated other comprehensive income consistent with the guidance in place prior to the issuance of ASU No. 2011-05. While the Board is considering the operational concerns about presentation requirements for reclassification adjustments, it stated that the deferral did not affect the requirement to report comprehensive income either in a single continuous financial statement or in two separate but consecutive financial statements. The amendment, which must be applied retrospectively, is effective for interim and annual periods beginning after December 15, 2011, with early adoption permitted. We adopted this standard during the second quarter of 2012. The adoption of this amendment did not have a material impact on our consolidated financial statements.
