New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New accounting pronouncements	New accounting pronouncements In October 2009, the FASB issued new guidance for arrangements with multiple deliverables under which a company is required to use its best estimate of selling price for the deliverables in an arrangement when vendor specific objective evidence or third party evidence of the selling price is not available. We adopted the updated guidance, including the requirement for expanded qualitative and quantitative disclosures, effective January 1, 2011. The implementation of this new guidance did not have a material impact on our consolidated financial statements. In May 2011, the FASB issued new authoritative guidance to provide a consistent definition of fair value and ensure that fair value measurements and disclosure requirements are similar between GAAP and International Financial Reporting Standards. This guidance changes certain fair value measurement principles and enhances the disclosure requirements for fair value measurements. This guidance is effective for interim and annual periods beginning after December 15, 2011 and is applied prospectively. We are currently evaluating the impact such guidance will have on our consolidated financial statements. In June 2011, the FASB amended its guidance on the presentation of comprehensive income in financial statements to improve the comparability, consistency and transparency of financial reporting and to increase the prominence of items that are recorded in other comprehensive income. The new accounting guidance requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. This guidance is effective for interim and annual periods beginning after December 15, 2011. We do not believe this guidance will have a material impact on our consolidated financial statements. In September 2011, the FASB issued ASU 2011-08 which provides an entity the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test for goodwill impairment. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. The revised standard is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. However, an entity can choose to early adopt even if its annual test date is before the issuance of the final standard, provided that the entity has not yet performed its 2011 annual impairment test or issued its financial statements. The adoption of this ASU is not expected to significantly impact the Company’s consolidated financial statements.
