New Accounting Pronouncements
New Accounting Pronouncements	(3) New Accounting Pronouncements The following is a summary of new accounting pronouncements that apply or may apply to our business. In September 2009, the Financial Accounting Standards Board ("FASB") issued guidance with the objective of amending revenue recognition for arrangements with multiple deliverables. The guidance eliminates one previous revenue recognition criterion so that objective and reliable evidence of fair value for undelivered item(s), in a multiple element deliverable arrangement in which the delivered item or items are considered a separate unit or units, is no longer required. The guidance also determines a hierarchy for an entity to use when estimating the selling price of deliverables that meet the other two conditions for separation as follows: (1) vendor-specific objective evidence of the selling price, (2) third-party evidence of the selling price, or (3) an estimate of the selling price. In addition, the term "selling price" replaces all references to fair value in the guidance. The guidance also has eliminated the residual allocation method and requires an entity to apply the relative selling price allocation method in all circumstances where there is an absence of objective and reliable evidence for the delivered item(s) in an arrangement. Lastly, the guidance requires enhanced disclosures about the judgments and assumptions used in evaluating arrangements. Entities may elect to apply this guidance (1) prospectively to new or materially modified arrangements after the effective date or (2) retrospectively for all periods presented. The guidance is effective for fiscal years beginning on or after June 15, 2010. We adopted this guidance on January 1, 2011 with no material impact on our consolidated financial statements. In September 2009, the FASB issued an amendment to guidance related to revenue recognition for certain revenue arrangements that include software elements. The amendment was to the scope of prior guidance, such that all tangible products containing both software and non-software components that function together to deliver the product's essential functionality will no longer be within the scope of the Software Revenue Recognition Topic of the Codification. That is, the entire product (including the software deliverables and non-software deliverables) would be outside the scope of revenue recognition guidance specific to software and would be accounted for under other accounting literature. Lastly, the guidance requires enhanced disclosures about the judgments and assumptions used in evaluating arrangements. Entities may elect to apply this guidance (1) prospectively to new or materially modified arrangements after the effective date or (2) retrospectively for all periods presented. The guidance is effective for fiscal years beginning on or after June 15, 2010. We adopted this guidance on January 1, 2011 with no material impact on our consolidated financial statements. In January 2010, the FASB issued an amendment to guidance related to fair value disclosures. The amendment adds new requirements for disclosures about (1) transfers in and out of Levels 1 and 2 fair value measurements in which a reporting entity should disclose separately the amounts of significant transfers in and out of Levels 1 and 2 fair value measurements and the reasons for the transfers, and (2) the activity in Level 3 fair value measurements, including the reconciliation for fair value measurements using significant unobservable inputs in which an entity should present separately information about purchases, sales, issuances, and settlements. This amendment provides clarification of existing disclosures for (1) the level of disaggregation for fair value measurement disclosures for each class of assets and liabilities and (2) the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements required for Levels 2 or 3. Lastly, this update amends guidance on employers' disclosures about postretirement benefit plan assets to require that disclosures be provided by classes of assets instead of by major categories of assets. The disclosure requirements for significant transfers in and out of Levels 1 and 2 are effective for periods beginning on or after December 15, 2009. We adopted this guidance on January 1, 2010 with no material impact on our consolidated financial statements. The requirement to provide the Level 3 activity of purchases, sales, issuances, and settlements on a gross basis is effective for fiscal years beginning after December 15, 2010. We adopted this guidance on January 1, 2011 with no material impact to our consolidated financial statements. In May 2011, the FASB issued guidance to develop a single, converged fair value framework, amend the requirements of fair value measurement and enhance related disclosure requirements, particularly for recurring Level 3 fair value measurements. This guidance clarifies the concepts of (i) the highest and best use and valuation premise for nonfinancial assets, (ii) application to financial assets and financial liabilities with offsetting positions in market risks or counterparty credit risk, (iii) premiums or discounts in fair value measurements and (iv) fair value measurement of an instrument classified in a reporting entity's shareholders' equity. The guidance is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2011, and must be applied prospectively. We adopted the guidance on January 1, 2012 with no material impact on our consolidated financial statements. In June 2011, and amended in December 2011, the FASB issued guidance to revise the presentation of comprehensive income by requiring entities to report components of comprehensive income in either a single continuous statement of comprehensive income or two separate but consecutive statements. The single continuous statement of comprehensive income must include the components of net income, a total for net income, the components of other comprehensive income ("OCI"), a total for OCI, and a total for comprehensive income. The separate but consecutive statements must report components of net income and total net income in the statement of net income, which must be immediately followed by a statement of OCI that must include the components of OCI, a total for OCI, and a total for comprehensive income. Each method requires entities to display adjustments for items that are reclassified from OCI to net income in both net income and OCI. The guidance is effective for the first reporting period in fiscal years beginning after December 15, 2011 and must be applied retrospectively for all periods presented in the financial statements. We retrospectively applied this guidance for all periods presented within this Form 10-K, with no material impact on our consolidated financial statements. In September 2011, the FASB issued an amendment to guidance related to testing goodwill for impairment. Under the revised guidance, entities testing goodwill for impairment have the option of performing a qualitative assessment 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 under Topic 350 of the Codification. If entities determine, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, the two-step impairment test would be required. The amendment is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We adopted the guidance for the year ended December 31, 2012, with no material impact on our consolidated financial statements. In December 2011, the FASB issued an amendment to disclosure requirements related to offsetting, whereby entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. These disclosures assist users of financial statements in evaluating the effect or potential effect of netting arrangements on a company's financial position, including the effect or potential effect of rights of setoff associated with the recognized assets and recognized liabilities within the scope. The amendment applies to a) recognized financial and derivative instruments that are offset in accordance with either ASC 210-20 or ASC 815-10 and b) financial and derivative instruments and other transactions that are subject to an enforceable master netting arrangement or similar agreement that covers similar instruments and transactions. This amendment will be effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods, and shall be applied retrospectively for all comparative periods presented. We have not yet adopted this guidance and do not expect the adoption to have a material impact on our consolidated financial statements. In July 2012, the FASB issued an amendment to guidance related to testing indefinite-lived intangible assets, other than goodwill, for impairment. Under the revised guidance, entities testing such assets for impairment have the option of first performing a qualitative assessment to determine whether it is more likely than not that the carrying amount of an indefinite-lived intangible asset exceeds its fair value. If an entity determines, on the basis of qualitative factors, that it is more likely than not that the indefinite-lived intangible asset is impaired, then the entity shall calculate the fair value of the intangible asset and perform the quantitative impairment test in accordance with the Intangibles — Goodwill and Other Topic of the Codification. The amendment is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted. We have not yet adopted this guidance and do not expect the adoption to have a material impact on our consolidated financial statements.
