Impact of Recently Issued Accounting Pronouncements [Abstract]
Impact of Recently Issued Accounting Pronouncements	(2) Impact of Recently Issued Accounting Pronouncements Fair Value Measurement In May 2011, the FASB issued "Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements" that established a framework for how to measure fair value and the disclosures required about fair value measurements. The updated guidance is largely consistent with fair value measurement principles that existed prior to the update and became effective on January 1, 2012. The effect of adopting this update did not have a material impact on the Company's financial position or results of operations. Comprehensive Income In June 2011, the FASB issued "Comprehensive Income - Presentation of Comprehensive Income." This statement gives companies two options for presenting other comprehensive income ("OCI"), which currently is included as part of the statement of shareholders' equity. An OCI statement can be included within the income statement, which together will make a statement of total comprehensive income. Alternatively, companies can have an OCI statement separate from an income statement, but the two statements will have to appear consecutively within a financial report. This statement is effective for fiscal quarters and years beginning after December 15, 2011. The effect of adopting this statement did not have an impact on the Company's financial position or results of operations. Testing Goodwill for Impairment In September 2011, the FASB issued "Intangibles-Goodwill and Other: Testing Goodwill for Impairment" to simplify the goodwill impairment test. The change allows companies to first decide whether they need to do the two-step test by allowing companies 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. A business no longer has to calculate the fair value of a reporting unit unless it believes it is very likely that the unit's fair value is less than the value carried on the balance sheet. This amendment also includes examples of how the amended test should be carried out. This amendment is effective for annual and interim tests performed for fiscal years beginning after December 15, 2011. The effect of adopting this statement does not have an impact on the Company's financial position or results of operations.
