Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements [Text Block]	Recent Accounting Pronouncements In December 2010, an accounting standard update was issued regarding the interpretation of the disclosure of supplementary pro forma information for business combinations. The standard clarifies that an entity is required to disclose pro forma revenue and earnings 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. In addition, this standard 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. This standard will be effective for the Company for fiscal year 2012. The Company currently complies with these disclosures and thus this standard will not have any impact on previously issued financial statements. In May 2011, an accounting standard update was issued to clarify existing fair value measurement guidance and expand the disclosure requirements for fair value measurements estimated using unobservable inputs (Level 3 inputs). New disclosures are required to report quantitative information about the unobservable inputs used in the measurement of Level 3 valuations and to include the valuation process used to determine the fair value of the item and the sensitivity of the measurement to changes in unobservable inputs. This standard will be effective for the Company for the third quarter of fiscal year 2012. The standard is unlikely to impact the fair value measurement of any of the Company’s existing assets, liabilities, or equity valuations, but additional disclosures will be required for the Company’s redeemable noncontrolling interest, which is measured using Level 3 inputs. In June 2011, an accounting standard update was issued regarding the presentation of other comprehensive income in the financial statements. The standard eliminates the option of presenting other comprehensive income as part of the statement of changes in stockholders’ equity and instead requires the entity to present other comprehensive income as either a single statement of comprehensive income combined with net income or as two separate but continuous statements. This amendment will be effective for the Company for fiscal year 2013 and interim periods therein. The Company currently reports other comprehensive income in the summary of changes in equity and comprehensive income and will be required to update the presentation of comprehensive income to be in compliance with the new standard. In September 2011, an accounting standard update was issued that simplifies how an entity tests goodwill for impairment by allowing an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. The revised standard includes examples of types of factors to consider in conducting the qualitative assessment. These include macro-economic conditions, such as a deterioration in the entity’s operating environment, entity-specific events, such as declining financial performance, and other events, such as an expectation that a reporting unit will be sold. The revised standard is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. The Company is likely to early adopt this standard for the goodwill impairment test to be performed in fiscal 2012. Upon adoption, this standard will impact how the Company assesses goodwill for impairment but will not change the measurement or recognition of a potential goodwill impairment charge. In September 2011, an accounting standard update was issued that requires additional disclosures about an employer’s participation in multiemployer pension plans. The revised disclosures provide additional information about the plans in which an employer participates, the level of its participation, the financial health of significant plans, and the nature of the employer’s commitments to the plans, including when the collective-bargaining agreements that require contributions to the significant plans are set to expire and whether those agreements require minimum contributions to be made to the plans. The revised disclosures also require additional information about significant plans from sources available outside of the basic financial statements, including the funded status of such plans. The revised standard does not change the existing recognition, measurement, and disclosure provisions for withdrawal liabilities. The revised standard will be effective for the Company for fiscal year 2012. The Company currently complies with the disclosure requirements of the revised standard.
