Accounting Standards Update 2011-04 [Member]
New Accounting Pronouncement or Change in Accounting Principle, Description	In May2011, the FASB issued FASB ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (" ASU 2011-04 "). ASU 2011-04 provides new guidance for fair value measurements intended to achieve common fair value measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards. The amended guidance provides a consistent definition of fair value to ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. The amended guidance changes certain fair value measurement principles and enhances the disclosure requirements, particularly for Level 3 fair value measurements. The amended guidance is effective for interim and annual periods beginning after December 15, 2011. Early adoption was not permitted. The Company conformed to the new presentation required in ASU 2011-04 beginning with Form 10-Q for the three months ended March 31, 2012.
Accounting Standards Update 2011-05 [Member]
New Accounting Pronouncement or Change in Accounting Principle, Description	In June 2011, the FASB issued Accounting Standards Update No. 2011-05, Presentation of Comprehensive Income ("ASU 2011-05"), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. The standard does not change the items which must be reported in other comprehensive income, how such items are measured or when they must be reclassified to net income. This standard is effective for interim and annual periods beginning after December 15, 2011 and is to be applied retrospectively. The FASB has deferred the requirement to present reclassification adjustments for each component of accumulated other comprehensive income in both net income and other comprehensive income. Companies are required to either present amounts reclassified out of other comprehensive income on the face of the financial statements or disclose those amounts in the notes to the financial statements. During the deferral period, there is no requirement to separately present or disclose the reclassification adjustments into net income. The effective date of this deferral will be consistent with the effective date of the ASU 2011-05. The Company adopted ASU 2011-05 in the first quarter of 2012 and disclosed comprehensive income in its unaudited consolidated statement of comprehensive income and note that this guidance affects financial statement presentation only and has no impact on the Company's consolidated financial statements.
Accounting Standards Update 2011-08 [Member]
New Accounting Pronouncement or Change in Accounting Principle, Description	In September 2011, the FASB issued ASU 2011-08, Testing for Goodwill Impairment ("ASU 2011-08"). ASU 2011-08 permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying amount before applying the two-step goodwill impairment test. If an entity concludes it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it need not perform the two-step impairment test. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 31, 2011. Early adoption was permitted. The implementation of ASU 2011-08 did not have a material impact on the Company's consolidated financial statements.
