New accounting standards | Note 2 — New accounting standards The Company adopted the following new accounting standards as of January 1, 2012, the first day of its 2012 fiscal year: Amendment to Guidance on Fair Value Measurement: In May 2011, the FASB amended guidance relating to fair value measurement and disclosure so that the requirements under GAAP and International Financial Reporting Standards (“IFRS”) are the same. The guidance clarifies the FASB’s intent about the application of existing fair value measurements and requires enhanced disclosures, most significantly related to unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. The amendment became effective prospectively for interim and annual periods beginning after December 15, 2011. Amendment to Guidance on Comprehensive Income: In June 2011, the FASB amended guidance relating to the presentation of comprehensive income within an entity’s financial statements. Under the guidance, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income in a single continuous statement or in two separate but consecutive statements. The amended guidance eliminates the previously available option of presenting the components of other comprehensive income as part of the statement of changes in equity. The amendment became effective for fiscal years beginning after December 15, 2011 and is applied retrospectively. The Company has elected to present the total of comprehensive income and the components of other comprehensive income in a separate statement immediately following the statement of income. The Company adopted the following new accounting standard in the fourth quarter of 2012: Amendment to Guidance on Intangibles-Goodwill and Other: In July 2012, the FASB issued updated guidance on the periodic testing of indefinite-lived intangible assets, other than goodwill, for impairment. This updated guidance permits companies to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test required under applicable accounting standards. Under the amended guidance, a company is no longer required to perform the quantitative impairment tests unless the company determines, based on a qualitative assessment, that it is more likely than not that the fair value of the asset is less than its carrying amount. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted.
