Under the newly issued guidance, net income and comprehensive income may only be presented either as one continuous statement or in two separate, but consecutive statements. The Company retrospectively adopted this guidance in the first quarter of fiscal year 2013, with comprehensive income shown as a separate statement immediately following the condensed consolidated statements of earnings.

The updated accounting guidance allows entities to first assess qualitative factors before performing a quantitative assessment of the fair value of a reporting unit. If it is determined 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 existing quantitative impairment test is required.

This newly issued accounting standard requires an entity to disclose both gross and net information about instruments and transactions eligible for offset in the balance sheet as well as instruments and transactions executed under a master netting or similar arrangement and was issued to enable users of financial statements to understand the effects or potential effects of those arrangements on its financial position. This accounting guidance is required to be applied retrospectively and is effective for the Company beginning in the first quarter of fiscal year 2014. Since the accounting guidance only impacts disclosure requirements, its adoption will not have a material impact on the Company's consolidated financial statements. In July 2012, the FASB updated the accounting guidance related to annual and interim indefinite-lived intangible asset impairment testing. The updated accounting guidance allows entities to first assess qualitative factors before performing a quantitative assessment of the fair value of indefinite-lived intangible assets. If it is determined on the basis of qualitative factors that the fair value of indefinite-lived intangible assets is more likely than not less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. The updated guidance is effective for the Company beginning in the first quarter of fiscal year 2014 with early adoption permitted under certain circumstances. The Company will adopt this accounting guidance in the first quarter of fiscal year 2014 and does not expect it to have a material impact on the Company's consolidated financial statements.

Recently Adopted

In June 2011, and subsequently amended in December 2011, the Financial Accounting Standards Board (FASB) issued final guidance on the presentation of comprehensive income. Under the newly issued guidance, net income and comprehensive income may only be presented either as one continuous statement or in two separate, but consecutive statements. The Company retrospectively adopted this guidance in the first quarter of fiscal year 2013, with comprehensive income shown as a separate statement immediately following the condensed consolidated statements of earnings. Since the new guidance only relates to presentation, its adoption did not impact the Company's financial position, results of operations, or cash flows.

In September 2011, the FASB updated the accounting guidance related to annual and interim goodwill impairment testing.
