Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	Note 8 — Recent Accounting Pronouncements In June 2011, the FASB issued an Accounting Standards Update (“ASU”) ASU 2011-05, Presentation of Comprehensive Income. Under the amendments to Topic 220, Comprehensive Income, an entity has the option 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. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. This eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amendments do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The guidance in ASU 2011-05 is effective for public companies for fiscal years, and interim periods within those years beginning after December 15, 2011. The Company expects that ASU 2011-05 will not have a material impact on the Company’s consolidated financial statements.
