Recently Issued Accounting Guidance [Abstract]
Balance Sheet	12. Recently Issued Accounting Guidance—In December 2011, FASB issued ASU No. 2011-11, Balance Sheet. In response to the requests from financial users for comparability on the differences that resulted in offsetting assets and liabilities under U.S. generally accepted accounting principles (U.S. GAAP) requirements versus International Financial Reporting Standards (“IFRS”) requirements, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board, (“IASB”) jointly issued this update to enhance current disclosures. Entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. This scope would include derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. The objective of this disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of IFRS. The amendments in this Update affect all entities that have financial instruments and derivative instruments that are either (1) offset in accordance with either Section 210-20-45 or Section 815-10-45 or (2) subject to an enforceable master netting arrangement or similar agreement. The requirements amend the disclosure requirements on offsetting in Section 210-20-50. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Company is evaluating the effect of this guidance but does not expect it to have a significant impact on its financial statements.
