New Accounting Pronouncements, Policy [Policy Text Block]	Effective January 1, 2012, the Company adopted the provisions of Accounting Standards Update, or ASU, No. 2011-05, Comprehensive Income (Topic 220) Presentation of Comprehensive Income, or ASU No. 2011-05, and began presenting the total of comprehensive income, the components of net income and the components of other comprehensive income in two separate but consecutive statements. The provisions of ASU No. 2011-05 are required to be adopted retroactively. As this guidance provides only presentation requirements, the adoption of this standard did not impact our results of operations, cash flows, or financial position. In September 2011, the Financial Accounting Standards Board issued ASU No. 2011-08, Intangibles - Goodwill and Other (Topic 350). ASU 2011-08 allows entities to first assess qualitatively whether it is necessary to perform the two-step goodwill impairment test. If an entity believes, as a result of its qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative two-step goodwill impairment test is required. An entity has the unconditional option to bypass the qualitative assessment and proceed directly to performing the first step of the goodwill impairment test. ASU 2011-08 was effective for the Company's first quarter of 2012. The Company performs its annual goodwill impairment test during the fourth quarter. The Company does not believe adoption of this standard during the fourth quarter of 2012 will have an impact on its consolidated results of operations, financial condition, or cash flows. There were no additional accounting pronouncements recently issued in the six-month period ended June 30, 2012, which are applicable to the Company or may be considered material to the Company. For a complete discussion of the impact of recent accounting pronouncements, please refer to Note 2 of the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2011.
