Notes To Financial Statements [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In May 2011, the FASB issued ASU No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” This update provides clarification on existing fair value measurement requirements, amends existing guidance primarily related to fair value measurements for financial instruments, and requires enhanced disclosures on fair value measurements. The additional disclosures are specific to Level 3 fair value measurements, transfers between Level 1 and Level 2 of the fair value hierarchy, financial instruments not measured at fair value and use of an asset measured or disclosed at fair value differing from its highest and best use. The company adopted the provisions of ASU No. 2011-04 on January 1, 2012. There was no impact to the company’s financial position, results of operations or cash flows. In June 2011 and December 2011, the FASB issued ASU No. 2011-05, “Presentation of Comprehensive Income” and ASU No. 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 No. 2011-05”, respectively. ASU No. 2011-05 eliminated the option to present the components of other comprehensive income in the statement of changes in stockholders’ equity. Instead, entities have the option to present the components of net income, the components of other comprehensive income and total comprehensive income in a single continuous statement or in two separate but consecutive statements. The guidance does not change the items reported in other comprehensive income or when an item of other comprehensive income is reclassified to net income. The company adopted the provisions of ASU No. 2011-05 on January 1, 2012. As this guidance only revises the presentation of comprehensive income, there was no impact to the company’s financial position, results of operations or cash flows. For interim reporting purposes, the company has elected to present comprehensive income in a single continuous statement now referred to as the Condensed Consolidated Statements of Comprehensive Income. In September 2011, the FASB issued ASU No. 2011-08, “Intangibles – Goodwill and Other (Topic 350).” This ASU will allow an entity the option to make a qualitative evaluation about the likelihood of goodwill impairment to determine whether it should calculate the fair value of a reporting unit. The ASU also amends previous guidance by expanding upon the examples of events and circumstances that an entity should consider between annual impairment tests in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Also, the ASU provides additional examples of events and circumstances that an entity having a reporting unit with a zero or negative carrying amount should consider in determining whether to measure an impairment loss, if any, under the second step of the goodwill impairment test. The company adopted the provisions of ASU 2011-08 on January 1, 2012. There was no impact to the company’s financial position, results of operation or cash flows. The company will determine whether to apply the qualitative evaluation allowed under this ASU in connection with the company’s annual goodwill impairment test. On July 27, 2012, the FASB issued ASU 2012-02, “Intangibles - Goodwill and Other (Topic 350)”. Similar to ASU 2011-08, this ASU amends the guidance in ASC 350-30. While ASU 2011-08 allows an entity the option to make a qualitative evaluation about the likelihood of goodwill impairment to determine whether it should calculate the fair value of a reporting unit, ASU-2012-02 allows an entity the option to make a qualitative evaluation to determine whether the existence of events and circumstances indicate that it is more likely than not the indefinite-lived intangible asset is impaired thus requiring the entity to perform quantitative impairment tests in accordance with ASC 350-30. The ASU also amends previous guidance by expanding upon the examples of events and circumstances that an entity should consider when making the qualitative evaluation. The company is currently evaluating its adoption approach to this guidance.
