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.

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.
