New Accounting Standards [Abstract]
Amendment To Revenue Recognition	Amendment to Revenue Recognition: In October 2009, the Financial Accounting Standards Board ("FASB") revised the criteria for multiple-deliverable revenue arrangements by establishing new guidance on how to separate deliverables and how to measure and allocate arrangement consideration to one or more units of accounting. Additionally, the guidance required companies to expand their disclosures regarding multiple-deliverable revenue arrangements. The guidance became effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The amendment did not have an impact on the Company's results of operations, cash flows or financial position.
Amendment To Intangibles-Goodwill And Other	Amendment to Intangibles-Goodwill and Other: In September 2011, the FASB revised its requirements related to an entity's approach in performing a goodwill impairment test. Under the revised requirements, an entity is permitted 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 previously required under applicable guidance. The revised requirements became effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 with early adoption permitted.
Amendment To Fair Value Measurement	Amendment to Fair Value Measurement: In May 2011, the FASB revised the fair value measurement and disclosure requirements so that the requirements under GAAP and International Financial Reporting Standards ("IFRS") are the same. The guidance clarifies the FASB's intent about the application of existing fair value measurements and requires enhanced disclosures, most significantly related to unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. The guidance is effective prospectively during interim and annual periods beginning after December 15, 2011.
Amendment To Comprehensive Income	Amendment to Comprehensive Income: In June 2011, the FASB amended guidance relating to the presentation requirements of comprehensive income within an entity's financial statements. Under the guidance, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income in a single continuous statement or in two separate but consecutive statements. The amended guidance eliminates the previously available option of presenting the components of other comprehensive income as part of the statement of changes in equity. In addition, an entity is required to present adjustments on the face of the financial statements for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The amendment is effective for fiscal years beginning after December 15, 2011 and will be applied retrospectively, with the exception of the requirement to present reclassification adjustments from other comprehensive income to net income on the face of the financial statements, which has been deferred pending further deliberation by the FASB.
