16. Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2011-08, "Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment." Under the amendments in this guidance, an entity may consider qualitative factors before applying Step 1 of the goodwill impairment assessment, but may no longer be permitted to carry forward estimates of a reporting unit's fair value from a prior year when specific criteria are met. These amendments are effective for goodwill impairment tests performed in fiscal years beginning after December 15, 2011. Early adoption is permitted. We are currently evaluating the effect of this guidance on our condensed consolidated financial statements.

In June 2011, the FASB issued Accounting Standards Update 2011-05, "Comprehensive Income (Topic 220): Statement of Comprehensive Income." Under the amendments in this guidance, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. The amendments in this guidance do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. These amendments are effective for fiscal years beginning after December 15, 2011. Early adoption is permitted. We elected to adopt this guidance as of May 1, 2011, and it did not have an effect on our presentation of comprehensive income in our condensed consolidated financial statements.

In May 2011, the FASB issued Accounting Standards Update 2011-04, "Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs." Under the amendments in this guidance, an entity will be required to provide additional disclosures about the valuation processes and sensitivities of Level 3 assets and the categorization by level of the fair value hierarchy for items that are not measured at fair value in the statement of financial position, but for which the fair value is required to be disclosed These amendments are effective for interim and annual periods beginning after December 15, 2011. Early adoption is not permitted. We do not expect this guidance to have a material effect on our condensed consolidated financial statements.

In April 2011, the FASB issued Accounting Standards Update 2011-02, "Receivables (Topic 310) – A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring." This guidance assists in determining if a loan modification qualifies as a TDR and requires that creditors must determine that a concession has been made and the borrower is having financial difficulties. We adopted this guidance as of May 1, 2011. We did not identify any new TDRs attributable to this new guidance and it did not have a material effect on our condensed consolidated financial statements.

In October 2009, the FASB issued Accounting Standards Update 2009-13, "Revenue Recognition (Topic 605) – Multiple-Deliverable Revenue Arrangements." This guidance amends the criteria for separating consideration in multiple-deliverable arrangements to enable vendors to account for products or services (deliverables) separately rather than as a combined unit. This guidance establishes a selling price hierarchy for determining the selling price of a deliverable, which is based on: (1) vendor-specific objective evidence; (2) third-party evidence; or (3) estimates. This guidance also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. In addition, this guidance significantly expands required disclosures related to a vendor's new multiple-deliverable revenue arrangements. We adopted this guidance as of May 1, 2011 and it did not have a material effect on our condensed consolidated financial statements.

In December 2010, the FASB issued Accounting Standards Update 2010-28, "Intangibles – Goodwill and Other (Topic 350): When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts." The amendments affect reporting units whose carrying amount is zero or negative, and require performance of 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, a reporting unit would consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with existing guidance. The reporting unit would evaluate if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. We adopted this guidance as of May 1, 2011 and it did not have a material effect on our condensed consolidated financial statements.

In December 2010, the FASB issued Accounting Standards Update 2010-29, "Business Combinations (Topic 805): Disclosure of Supplementary Pro Forma Information for Business Combinations." The amendments in this guidance specify that if a public entity presents comparative financial statements, the entity would disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. Additionally, disclosures should be accompanied by a narrative description about the nature and amount of material, nonrecurring pro forma adjustments. We adopted this guidance as of May 1, 2011 and it did not have a material effect on our condensed consolidated financial statements.
