New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Accounting Standards Update (“ASU”) No. 2011-08 - “Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment” (“ASU 2011-08”) In September 2011, the Financial Accounting Standards Board ("FASB") issued ASU 2011-08, which is intended to reduce the complexity and cost of performing an evaluation of impairment of goodwill. Under the new guidance, an entity will have the option of first assessing qualitative factors (events and circumstances) to determine whether it is more likely than not (meaning a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount. If, after considering all relevant events and circumstances, an entity determines 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 will be unnecessary. The amendments will be effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, although early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Company's consolidated financial statements. Accounting Standards Update No. 2011-09 - “Compensation - Retirement Benefits - Multiemployer Plans (Subtopic 715-80)” (“ASU 2011-09”) In September 2011, the FASB issued ASU 2011-09, which requires that employers provide additional separate disclosures for multiemployer pension plans and multiemployer other postretirement benefit plans. The additional quantitative and qualitative disclosures will provide users with more detailed information about an employer's involvement in multiemployer pension plans. The amendments will be effective for annual disclosures for multiemployer pension plans and multiemployer other postretirement benefit plans for fiscal years ending after December 15, 2011. The Company anticipates that the adoption of this standard will expand its consolidated financial statement footnote disclosures, but otherwise is not expected to have a material impact on our financial statements. Accounting Standards Update No. 2011-04 - “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. Generally Accepted Accounting Principles and IFRSs” (“ASU 2011-04”) ASU 2011-04 generally provides a uniform framework for fair value measurements and related disclosures between generally accepted accounting principles and international financial reporting standards (“IFRS”). Additional disclosure requirements in the update include: (1) for Level 3 fair value measurements, quantitative information about the unobservable inputs used, a description of the valuation processes used by the entity, and a qualitative discussion about the sensitivity of the measurements to changes in the unobservable inputs; (2) for an entity's use of a nonfinancial asset that is different from the asset's highest and best use, the reason for the difference; (3) for financial instruments not measured at fair value but for which disclosure of fair value is required, the fair value hierarchy level in which the fair value measurements were determined; and (4) the disclosure of all transfers between Level 1 and Level 2 of the fair value hierarchy. ASU 2011-04 will be effective for interim and annual periods beginning on or after December 15, 2011, which for the Company will be its first quarter of 2012. The Company is currently evaluating the impact that ASU 2011-04 will have on its financial statements. Accounting Standards Update No. 2011-05 - “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (“ASU 2011-05”) ASU 2011-05 amends existing guidance by allowing only two options for presenting the components of net income and other comprehensive income: (1) in a single continuous financial statement and statement of comprehensive income; or (2) in two separate but consecutive financial statements, consisting of an income statement followed by a separate statement of other comprehensive income. The FASB has decided to defer the specific requirement to present items that are reclassified from other comprehensive income to net income alongside their respective components of net income and other comprehensive income. ASU 2011-05 requires retrospective application, and it is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 (for the Company this will be its first quarter 2012), with early adoption permitted. The Company believes the adoption of this update will change the order in which certain financial statements are presented and provide additional detail on those financial statements when applicable, but will not have any other impact on its financial statements. Adoption of Accounting Standards Update No. 2010-17, “Revenue Recognition—Milestone Method” (“ASU 2010-17”) In April 2010, the FASB issued ASU 2010-17, which is included in ASC 605—Milestone Method of Revenue Recognition. This ASU codifies the consensus reached in Emerging Issues Task Force 08-09, “Milestone Method of Revenue Recognition,” and addresses the accounting when entities enter into revenue arrangements with multiple payment streams for a single deliverable or a single unit of accounting. The pronouncement shall be applied prospectively to milestones achieved in fiscal years, and interim periods within those years, beginning after June 15, 2010, with earlier application and retrospective application permitted. The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements. Adoption of ASU No. 2010-29, “Business Combinations (Topic 805): Disclosure of Supplementary Pro Forma Information for Business Combinations” (“ASU 2010-29”) In December 2010, the FASB issued ASU 2010-29. The amendments in this update are effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. The adoption of this pronouncement affected the Company's disclosure related to its acquisitions.
