In May 2011, the Financial Accounting Standards Board (FASB) issued guidance resulting in common fair value measurement disclosure requirements between U.S. GAAP and International Financial Reporting Standards. Consequently, the amendments change the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and disclosing information about fair value measurements. Some of the requirements clarify the FASB's intent about the application of existing fair value measurement requirements while other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The amendments in this guidance are effective prospectively for interim and annual periods beginning after December 15, 2011, with no early adoption permitted. This standard will be effective for us beginning with the quarter ending March 31, 2012. We do not expect the adoption to have a material impact on our consolidated financial statements.
 
In June 2011, the FASB issued guidance that improves the comparability, consistency, and transparency of financial reporting and increases the prominence of items reported in other comprehensive income by eliminating the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The amendments in this guidance require that all nonowner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Under either method, adjustments must be displayed for items that are reclassified from other comprehensive income to net income, in both net income and other comprehensive income. The standard does not change the current option for presenting components of other comprehensive income gross or net of the effect of income taxes, provided that such tax effects are presented in the statement in which OCI is presented or disclosed in the notes to the financial statements. Additionally, the standard does not affect the calculation or reporting of earnings per share. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 and are to be applied retrospectively, with early adoption permitted. This standard will be effective for us beginning with the quarter ending March 31, 2012. The adoption of this guidance will not have an impact on our consolidated financial statements.
 
In September 2011, the FASB issued guidance to simplify the testing of goodwill for impairment. The amendments to this guidance 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 FASB ASC Topic 350, "Intangibles-Goodwill and Other" (ASC Topic 350). The more-likely-than-not threshold is defined as having a likelihood of more than fifty percent. Previous guidance under ASC Topic 350 required an entity to test goodwill for impairment, on at least an annual basis, by comparing the fair value of a reporting unit with its carrying amount, including goodwill (step one). If the fair value of a reporting unit is less than its carrying amount, then the second step of the test must be performed to measure the amount of the impairment loss, if any. Under the amendments in this guidance, 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 amendments are effective for annual and interim impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. This standard will be effective for us beginning with the quarter ending March 31, 2012. The adoption of this guidance will not have an impact on our consolidated financial statements.
