Recent Accounting Pronouncements [Abstract]
Description Of New Accounting Pronouncements Not Yet Adopted	3. Recent Accounting Pronouncements Accounting Standards Codification ("ASC") 220 "Comprehensive Income." In December 2011, Accounting Standards Update ("ASU") 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update 2011-05" was issued. This ASU defers the ASU 2011-05 requirement that companies present accumulated other comprehensive income in both net income and other comprehensive income on the face of the financial statements. The ASU also defers the requirement to report reclassification adjustments in interim periods. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Adoption of this ASU did not have a material effect on the Company's consolidated financial results. ASC 820 "Fair Value Measurement." In May 2011, ASU Update No. 2011-04, "Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs" was issued. The amendments in this ASU result in common fair value measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards ("IFRS"). Consequently, the amendments converge the fair value measurement guidance in U.S. GAAP and IFRS. Some of the amendments clarify the application of existing fair value measurement requirements, while other amendments change a particular principle in ASC 820. The amendments in this ASU that change a particular principle or requirement for measuring fair value or disclosing information about fair value measurements include the following: 1) measuring the fair value of financial instruments that are managed within a portfolio, 2) application of premiums and discounts in a fair value measurement, and 3) additional disclosures about fair value measurements. The amendments in this ASU are to be applied prospectively and are effective during interim and annual periods beginning after December 15, 2011. Adoption of this ASU did not have a material impact on the Company's consolidated financial statements. ASC 350 "Intangibles - Goodwill and Other." In September 2011, ASU No. 2011-08, "Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment" was issued. The objective of this ASU is to simplify how entities, both public and nonpublic, test goodwill for impairment. The ASU permits an entity 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 described in Topic 350. The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent. Previous guidance under Topic 350 required an entity to test goodwill for impairment, on at least an annual basis, by comparing the fair value of a reporting unit with its carrying amount, including goodwill (step one). If the fair value of a reporting unit is less than its carrying amount, then the second step of the test must be performed to measure the amount of the impairment loss, if any. Under this ASU, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This ASU is effective for annual or interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The Company did not adopt this ASU since adoption was optional.
