Recent Accounting Pronouncements [Abstract]
Description of New Accounting Pronouncements Not yet Adopted	Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2011-05, Comprehensive Income (Topic 220)—Presentation of Comprehensive Income. ASU 2011-05 requires 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. In both choices, an entity is required to present each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The amendments in this update 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. This pronouncement is effective for the Company in 2012. Early adoption of the new guidance is permitted and full retrospective application is required. As ASU 2011-05 relates only to the presentation of Comprehensive Income, the Company does not expect to adopt this new guidance early. This amendment will change the manner in which the Company presents comprehensive income.
