New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Update ("ASU") No. 2013-02 - “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU 2013-02”) In February 2013, the Financial Accounting Standards Board ("FASB") issued ASU 2013-02, which is intended to improve the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. The adoption of this pronouncement is not expected to have a material impact on the Company's consolidated financial statements. ASU No. 2011-08 - “Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment” (“ASU 2011-08”) In September 2011, the FASB issued ASU 2011-08, which is intended to reduce the complexity and cost of performing an evaluation of impairment of goodwill. Under the 2011 guidance, an entity has 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 are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The adoption of this pronouncement did not have a material impact on the Company's consolidated financial statements. ASU 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 are effective for annual disclosures for multiemployer pension plans and multiemployer other postretirement benefit plans for fiscal years ending after December 15, 2011. The adoption of this pronouncement did not have a material impact on the Company's consolidated financial statements. ASU 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 IFRS” (“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 is effective for interim and annual periods beginning on or after December 15, 2011. The adoption of this pronouncement did not have a material impact on the Company's consolidated financial statements. ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (“ASU 2011-05”) and 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") ASU 2011-05 allows an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in equity. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. In December 2011, the FASB issued ASU 2011-12 , which deferred certain aspects of ASU 2011-05. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of this pronouncement did not have a material impact on the Company's consolidated financial statements.
