The amendments in this accounting standard update are intended to reduce complexity and costs by allowing an entity the option to make a qualitative evaluation about the likelihood of goodwill impairment to determine whether it should calculate the fair value of a reporting unit. The amendments also improve previous guidance by expanding upon the examples of events and circumstances that an entity should consider between annual impairment tests in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendments in this accounting standard update are effective for interim and annual goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The adoption of this accounting standard update will not have an impact on our consolidated financial position, results of operations, or cash flows, as it is intended to simplify the assessment for goodwill impairment. In June 2011, the FASB issued an accounting standard update which requires the presentation of the components of other comprehensive income as either (1) a continuous statement of comprehensive income that contains two sections, net income and other comprehensive income, or (2) two separate but consecutive statements. Companies will no longer be allowed to present components of other comprehensive income as part of the statement of shareholders’ equity. This update is effective for interim and annual periods beginning after December 15, 2011. As this accounting standard is only related to presentation, we do not believe the adoption of this accounting standard update will have an impact on our consolidated financial position, results of operations, or cash flows. In May 2011, the FASB issued an accounting standard update that amends the accounting standard on fair value measurements. This update clarifies the definition and measurement of fair value to increase consistency and aligns disclosure requirements between U.S. generally accepted accounting principles and International Financial Reporting Standards. The accounting standard update changes certain fair value measurement principles, clarifies the application of existing fair value measurement, and expands the fair value measurement disclosure requirements, particularly for Level 3 fair value measurements. These changes are to be applied prospectively and are effective for interim and annual periods beginning after December 15, 2011. We do not expect the adoption of this accounting standard update to have a material effect on our consolidated financial statements.
