Recent Accounting Pronouncements [Abstract]
Fair Value Measurements and Disclosures	In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS.” The ASU is the result of joint efforts by the FASB and International Accounting Standards Board to develop a single, converged fair value framework on how (not when) to measure fair value and what disclosures to provide about fair value measurements. While the ASU is largely consistent with existing fair value measurement principles in U.S. GAAP, it modifies Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”) to expand existing disclosure requirements for fair value measurements and makes other amendments. The Company adopted ASU 2011-04 on January 1, 2012 and such adoption did not have a material impact on the consolidated financial statements.
Presentation of Comprehensive Income	In June 2011, the FASB issued ASU 2011-05, “Presentation of Comprehensive Income.” This ASU revises the manner in which entities present comprehensive income in their financial statements. The new guidance removes the presentation options in ASC Topic 220, “Comprehensive Income” and requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The ASU does not change the items that must be reported in other comprehensive income. The Company adopted ASU 2011-05 on January 1, 2012 and has presented consolidated net income and consolidated comprehensive income in two separate, but consecutive, statements.
Impairment of goodwill	In September 2011, the FASB issued ASU 2011-08 “Testing Goodwill for Impairment.” This ASU 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. The Company adopted ASU 2011-08 on January 1, 2012 and such adoption did not have a material impact on the consolidated financial statements.
