Recently Issued Accounting Pronouncements [Abstract]
Recently Issued Accounting Pronouncements	Note 2. Recently Issued Accounting Pronouncements In December 2010, the FASB issued ASU 2010-28, When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts (Topic 350)—Intangibles—Goodwill and Other. ASU 2010-28 amends the criteria for performing Step 2 of the goodwill impairment test for reporting units with zero or negative carrying amounts and requires performing Step 2 if qualitative factors indicate that it is more likely than not that a goodwill impairment exists. ASU 2010-28 requires any impairment to be recorded upon adoption as an adjustment to our beginning retained earnings. The adoption of ASU 2010-28 on May 1, 2011 did not have a material impact on our consolidated financial statements. In December 2010, the FASB issued ASU 2010-29, Business Combinations (Topic 805) — Disclosure of Supplementary Pro Forma Information for Business Combinations. This update clarifies that, when presenting comparative financial statements, registrants should disclose revenue and earnings of the combined entity as though the current period business combinations had occurred as of the beginning of the comparable prior annual reporting period only. The update also expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. ASU 2010-29 is effective prospectively for material (either on an individual or aggregate basis) business combinations entered into in fiscal years beginning on or after December 15, 2010, with early adoption permitted. ASU 2010-29 will be effective for us for any acquisitions we make after April 30, 2011. In May 2011, the FASB issued ASU 2011-04, Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRS, which amends ASC 820, Fair Value Measurements and Disclosures. ASU 2011-04 provides a consistent definition of fair value and ensures that the fair value measurement and disclosure requirements are similar between U.S. generally accepted accounting principles (“GAAP”) and International Financial Reporting Standards. ASU 2011-04 also changes certain fair value measurement principles and enhances the disclosure requirements particularly for level 3 fair value measurements. ASU 2011-04 is effective during interim and annual periods beginning after December 15, 2011. These new standards will be effective for us beginning in the third quarter of fiscal 2012. As ASU 2011-04 impacts presentation only, the adoption of this update will not impact our consolidated financial statements. In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income, an update to ASC 220, Comprehensive Income. ASU 2011-05 requires the components of net income and the components of other comprehensive income to be presented either in a single continuous statement of comprehensive income or in two separate but continuous statements. ASU 2011-05 eliminates the option to present components of other comprehensive income as part of the statement of changes in shareholders' equity. In addition, ASU 2011-05 requires that we present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. ASU 2011-05 is effective for annual periods beginning after December 15, 2011 and interim periods thereafter. As ASU 2011-05 impacts presentation only, the adoption of this update will not have a material impact on our consolidated financial statements.
