Accounting Standards Updates and Recently Issued Accounting Standards Updates [Abstract]
Accounting Standards Updates and Recently Issued Accounting Standards Updates	3. Accounting Standards Updates and Recently Issued Accounting Standards Updates Recently Issued Accounting Standards Updates In May 2011, an update was made to the Fair Value Measurement Topic, ASC 820, which is the result of joint efforts by the Financial Accounting Standards Board and International Accounting Standards Board to develop a single, converged fair value framework on how to measure fair value and on what disclosures to provide about fair value measurements. While the update is largely consistent with existing fair value measurement principles in GAAP, it expands ASC 820's existing disclosure requirements for fair value measurements and makes other amendments. Many of these amendments were made to eliminate unnecessary wording differences between GAAP and International Financial Reporting Standards. This update was effective for us on January 1, 2012 and did not have a material impact on our condensed consolidated financial statements. In June 2011, an update was made to the Comprehensive Income Topic, ASC 220, which provides guidance for the manner in which entities present comprehensive income in their financial statements. The update removes the presentation options in ASC 220 and requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The update does not change the items that must be reported in other comprehensive income nor does it require any additional disclosures. This update was effective for us on January 1, 2012. The adoption of this update only had an impact on the presentation of our condensed consolidated financial statements, not the financial results. In September 2011, an update was made to the Goodwill and Intangible Assets Topic, ASC 350, which amends the accounting guidance on goodwill impairment testing. The amendments in this 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. This update was effective for us on January 1, 2012 and did not have a material impact on our condensed consolidated financial statements.
