Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	2. Recent Accounting Pronouncements In May 2011, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRSs”) to provide a consistent definition of fair value and ensure that fair value measurements and disclosure requirements are similar between U.S. GAAP and IFRSs. This guidance changes certain fair value measurement principles and enhances the disclosure requirements for fair value measurements. The amendments in this ASU are effective for interim and annual fiscal periods beginning after December 15, 2011 and are applied prospectively. Early adoption by public entities is not permitted. The Company does not expect adoption of ASU 2011-04 will have a material impact on the Company’s financial position, results of operations or cash flows.
