Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Accounting Pronouncements In December 2011, the FASB issued Accounting Standards Update (“ASU”) 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities. Under the new requirements, entities must disclose both gross information and net information about instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. ASU 2011-11 is effective for annual periods beginning January 1, 2013, and interim periods within those annual periods. The Company expects to comply with the disclosure requirements of this ASU for the quarter ending March 31, 2013. In September 2011, the FASB issued ASU 2011-09, Disclosures about an Employer's Participation in a Multiemployer Plan, an amendment to FASB ASC Subtopic 715-80, Compensation-Retirement Benefits-Multiemployer Plans. The update requires additional disclosures regarding the significant multiemployer plans in which an employer participates, the level of an employer's participation including contributions made, and whether the contributions made represent more than 5% of the total contributions made to the plan by all contributing employers. The expanded disclosures also address the financial health of significant multiemployer plans including the funded status and existence of funding improvement plans, the existence of imposed surcharges on contributions to the plan, as well as the nature of employer commitments to the plan. The Company adopted ASU 2011-09 beginning December 15, 2011 and amendments have been applied retrospectively for all prior periods presented. In September 2011, the FASB issued ASU 2011-08, Testing Goodwill for Impairment, an amendment to FASB ASC Topic 350, Intangibles - Goodwill and Other. The update provides an entity with the option to first assess qualitative factors in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. After assessing the qualitative factors, if an entity determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. If an entity concludes otherwise, then it is required to perform the first step of the two-step impairment test as described in FASB ASC Topic 350. Entities have the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step impairment test as well as resume performing the qualitative assessment in any subsequent period. The ASU is effective for the Company for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption was permitted, including for annual and interim goodwill impairment tests performed as of a date before September 15, 2011, if an entity’s financial statements for the most recent annual or interim period had not yet been issued. The Company did not early adopt the provisions of this ASU; however, the Company's annual goodwill impairment testing did not result in an impairment charge (Note 10). Accordingly, the Company does not expect the impact of adopting this ASU to be material to the Company's financial position, results of operations or cash flows. In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income, an amendment to FASB ASC Topic 220, Comprehensive Income. The update gives companies 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 separate but consecutive statements. The amendments in the update 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. This amendment also required an entity to present on the face of the financial statements adjustments for items that are reclassified from accumulated other comprehensive income to net income, however, in December 2011 the FASB issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05. The update 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. The Company adopted ASU 2011-05 and ASU 2011-12 beginning December 15, 2011 and amendments have been applied retrospectively for all prior periods presented. In May 2011, the FASB issued FASB ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, an amendment to FASB ASC Topic 820, Fair Value Measurement. The update revises the application of the valuation premise of highest and best use of an asset, the application of premiums and discounts for fair value determination, as well as the required disclosures for transfers between Level 1 and Level 2 fair value measures and the highest and best use of nonfinancial assets. The update provides additional disclosures regarding Level 3 fair value measurements and clarifies certain other existing disclosure requirements. The ASU is effective for the Company for interim and annual periods beginning after December 15, 2011. The Company does not expect the impact of adopting this ASU to have a material effect on the Company's consolidated financial statements, but the adoption of this ASU may require additional disclosures.
