FASB Accounting Standards Update No. 2011-05 [Member]
  
New Accounting Pronouncement or Change in Accounting Principle, Description In June 2011, the FASB issued the FASB Accounting Standards Update No. 2011-05 "Comprehensive Income" ("ASU 2011-05"), which was the result of a joint project with the IASB and amends the guidance in ASC 220, Comprehensive Income, by eliminating the option to present components of other comprehensive income (OCI) in the statement of stockholders' equity. Instead, the new guidance now gives entities the option to present all non-owner changes in stockholders' equity either as a single continuous statement of comprehensive income or as two separate but consecutive statements. Regardless of whether an entity chooses to present comprehensive income in a single continuous statement or in two separate but consecutive statements, the amendments require entities to present all reclassification adjustments from OCI to net income on the face of the statement of comprehensive income. The amendments in this Update should be applied retrospectively and are effective for public entity for fiscal years, and interim periods within those years, beginning after December 15, 2011.
FASB Accounting Standards Update No. 2011-08 [Member]
  
New Accounting Pronouncement or Change in Accounting Principle, Description In September 2011, the FASB issued the FASB Accounting Standards Update No. 2011-08 "Intangibles-Goodwill and Other: Testing Goodwill for Impairment" ("ASU 2011-08"). This Update is to simplify how public and nonpublic entities test goodwill for impairment. The amendments permit an entity 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 described in Topic 350. Under the amendments in this Update, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. The guidance is effective for interim and annual periods beginning on or after December 15, 2011. Early adoption is permitted.
FASB Accounting Standards Update No. 2011-11 [Member]
  
New Accounting Pronouncement or Change in Accounting Principle, Description In December 2011, the FASB issued the FASB Accounting Standards Update No. 2011-11 "Balance Sheet: Disclosures about Offsetting Assets and Liabilities" ("ASU 2011-11"). This Update requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. The objective of this disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of IFRS. The amended guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods.
FASB Accounting Standards Update No. 2012-02 [Member]
  
New Accounting Pronouncement or Change in Accounting Principle, Description In July 2012, the FASB issued the FASB Accounting Standards Update No. 2012-02 "Intangibles-Goodwill and Other (Topic 350) Testing Indefinite-Lived Intangible Assets for Impairment" ("ASU 2012-02"). This Update is intended to reduce the cost and complexity of testing indefinite-lived intangible assets other than goodwill for impairment. This guidance builds upon the guidance in ASU 2011-08, entitled Testing Goodwill for Impairment. ASU 2011-08 was issued on September 15, 2011, and feedback from stakeholders during the exposure period related to the goodwill impairment testing guidance was that the guidance also would be helpful in impairment testing for intangible assets other than goodwill. The revised standard allows an entity the option to first assess qualitatively whether it is more likely than not (that is, a likelihood of more than 50 percent) that an indefinite-lived intangible asset is impaired, thus necessitating that it perform the quantitative impairment test. An entity is not required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative impairment test unless the entity determines that it is more likely than not that the asset is impaired. This Update is effective for annual and interim impairment tests performed in fiscal years beginning after September 15, 2012. Earlier implementation is permitted.
