Newly Adopted Accounting Guidance [Abstract] |
Newly Adopted Accounting Guidance | 2. Newly Adopted Accounting Guidance Intangibles - Goodwill and Other In December 2010, the Financial Accounting Standards Board ("FASB") issued amended guidance to modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. We adopted the modified guidance on January 1, 2011. The adoption of the modified guidance did not have an impact on our financial position or results of operations. Multiple-Deliverable Revenue Arrangements In October 2009, the FASB issued new guidance that sets forth the requirements that must be met for an entity to recognize revenue for the sale of a delivered item that is part of a multiple-element arrangement when other elements have not yet been delivered. We adopted the new guidance on January 1, 2011. The adoption of the new guidance did not have a material impact on our financial position or results of operations. Business Combinations In December 2010, the FASB updated guidance to clarify the acquisition date that should be used for reporting the pro forma financial information disclosures when comparative financial statements are presented. We adopted the updated guidance on January 1, 2011. The adoption of the updated guidance did not have an impact on our financial statement disclosures. Fair Value Measurements and Disclosures In January 2010, the FASB updated the disclosure requirements for fair value measurements. The updated guidance requires companies to disclose separately the investments that transfer in and out of Levels 1 and 2 and the reasons for those transfers. Additionally, in the reconciliation for fair value measurements using significant unobservable inputs (Level 3), companies should present separately information about purchases, sales, issuances and settlements. We adopted the updated guidance on January 1, 2010, except for the disclosures about purchases, sales, issuances and settlements in the Level 3 reconciliation, which we adopted on January 1, 2011. The adoption of the updated guidance did not have an impact on our financial statement disclosures.
