Summary of Significant Accounting Policies [Abstract]
Recent accounting prounouncements	No accounting pronouncements adopted during the nine months ended September 30, 2011 had a material impact on the Company's consolidated financial statements. No new accounting pronouncements issued during the nine months ended September 30, 2011 but not yet adopted are expected to have a material impact on the Company's consolidated financial statements. In September 2011, the Financial Accounting Standards Board ("FASB") issued amended guidance on goodwill impairment testing. The amended guidance permits an entity to first perform a qualitative assessment to determine whether it is "more likely than not" that the fair value of a reporting unit is less than its carrying amount. If it is concluded that it is "more likely than not" that the fair value of a reporting unit is less than its carrying amount, it is then necessary to perform the two-step goodwill impairment test described in the 2010 Form 10-K. Otherwise, the two-step goodwill impairment test is not required. The Company adopted this amended guidance effective September 30, 2011, prior to performing its annual goodwill impairment test and, as such, anticipates performing the qualitative assessment in connection with the annual goodwill impairment test during the fourth quarter of 2011.
