Recent Accounting Pronouncements [Abstract]
Fair Value Measurement	In May 2011, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) ASU No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” ASU 2011-04 amends Topic 820 to provide common fair value measurement and disclosure requirements in U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) and International Financial Reporting Standards. Consequently, the amendments change the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements, as well as providing guidance on how fair value should be applied where its use is already required or permitted by other standards within U.S. GAAP. ASU No. 2011-04 is to be applied prospectively. For public entities, the amendments are effective during interim and annual periods beginning after December 15, 2011. The Company adopted this guidance in the first quarter of fiscal 2013 and it did not have a material impact on the Company’s financial position, results of operations or cash flows.
Presentation of Comprehensive Income	In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income. Under the amendments to Topic 220, Comprehensive Income, 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. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. This eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amendments 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. The guidance in ASU 2011-05 is effective for public companies for fiscal years, and interim periods within those years beginning after December 15, 2011. The Company adopted this guidance in the first quarter of fiscal 2013 and presented other comprehensive income (loss) in the Condensed Consolidated Statements of Income and Comprehensive Income (Loss).
Intangibles - Goodwill and Other	In September 2011, the FASB issued ASU 2011-08, “Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment.” ASU 2011-08 simplifies how entities test goodwill for impairment. ASU 2011-08 permits an entity to first assess qualitative factors 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 described in Topic 350. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The Company adopted this guidance in the first quarter of fiscal 2013. The adoption of ASU 2011-08 is not expected to have a material impact on the Company’s consolidated financial statements. In July 2012, the FASB issued ASU 2012-12, “Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment”, an update to their accounting guidance regarding indefinite-lived intangible asset impairment testing and whether it is necessary to perform the quantitative impairment test currently required. The guidance is effective for interim and annual periods beginning after September 15, 2012, with early adoption permitted. The adoption of this pronouncement will not have a material impact on the Company’s consolidated financial statements.
Comprehensive Income	In December 2011, the FASB issued ASU 2011-12, “Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” ASU 2011-12 defers the specific requirement to present items that are reclassified from accumulated other comprehensive income to net income separately with their respective components of net income and other comprehensive income. ASU 2011-12 did not defer the requirement to report comprehensive income either in a single continuous statement or in two separate but consecutive financial statements. The Company’s other comprehensive income represents foreign currency translation adjustments. The amendments are effective at the same time as the amendments in ASU 2011-05. The Company adopted this guidance in the first quarter of fiscal 2013 and it did not have any impact on the Company’s financial position, results of operations or cash flows.
Technical Corrections and Improvements	In October 2012, the FASB issued ASU 2012-04, “Technical Corrections and Improvements.” ASU 2012-04 contains amendments to clarify the ASC, correct unintended application of guidance, or make minor improvements to the ASC that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. Additionally, the amendments are intended to make the ASC easier to understand and the fair value measurement guidance easier to apply by eliminating inconsistencies and providing needed clarifications. The amendments that do not have transition guidance were effective upon issuance. The amendments that are subject to the transition guidance will be effective for fiscal periods beginning after December 15, 2012. The adoption of ASU 2012-04 will not have a material impact on the Company’s results of operations or financial position.
