Recently Adopted and Recently Issued Accounting Guidance In December 2010, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2010-28, Intangibles — Goodwill and Other (Topic 350). ASU 2010-28 modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those 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. ASU 2010-28 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of this update did not impact the Consolidated Financial Statements. In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, which amends current fair value measurement and disclosure guidance to provide increased transparency around valuation inputs and investment categorization. This update became effective prospectively for the Company in the first quarter of fiscal 2012. Other than additional disclosure requirements (refer to Note 19 —Fair Value of Financial Instruments), the adoption of this update did not impact the Consolidated Financial Statements. In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income. ASU 2011-05, as amended by ASU 2011-12, increases the prominence of other comprehensive income in financial statements. Under this update, an entity has the option to present the components of net income and comprehensive income in either a single continuous statement of comprehensive income or in two separate but consecutive statements. The Company has selected to report two separate statements. The update eliminates the option to present other comprehensive income in the statement of changes in stockholders’ equity. This update was effective on a retrospective basis for fiscal years, and interim periods within those years, beginning after December 15, 2011. Other than the change in presentation, the adoption of this update did not impact the Consolidated Financial Statements. In September 2011, the FASB issued ASU No. 2011-08, Intangibles—Goodwill and Other: Testing Goodwill for Impairment, which permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test. If an entity can support the conclusion that it is more likely than not that the fair value of a reporting unit is more than its carrying amount, it would not need to perform the two-step impairment test for that reporting unit. Goodwill must be tested for impairment at least annually, and prior to the ASU, a two-step test was required to assess goodwill for impairment. In Step 1, the fair value of a reporting unit is compared to the reporting unit’s carrying amount. If the fair value is less than the carrying amount, Step 2 is used to measure the amount of goodwill impairment, if any. The update was effective for annual and interim goodwill impairment tests performed in fiscal years beginning after December 15, 2011. The adoption of this update did not impact the Consolidated Financial Statements. In July 2012, the FASB issued ASU No. 2012-02, Intangibles—Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment, which simplifies the guidance for testing the decline in the realizable value (impairment) of indefinite-lived intangible assets other than goodwill. An organization is now allowed to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. These changes become effective for the Company on January 1, 2013. Adoption of this update will have no impact on the Consolidated Financial Statements. In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income—Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, entities are required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, entities are required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. These changes become effective for the Company on January 1, 2013. Management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements.
