Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements, Policy	Adoption of New Accounting Standards In May 2011, the Financial Accounting Standards Board (FASB) issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS, to amend FASB ASC 820, Fair Value Measurement, to improve comparability of fair value measurements in both U.S. GAAP and IFRS financial statements. Under these amendments, the FASB does not intend to cause any change in the application of the requirements under Topic 820. Some amendments provide clarification on the application of existing fair value measurement requirements, while other amendments change a particular principle or requirement for measuring fair value, or change disclosure requirements about fair value measurements. This guidance became effective for us on January 1, 2012, and the adoption had no effect on our financial position, results of operations or cash flows. In September 2011, the FASB issued ASU No. 2011- 08, Intangibles-Goodwill and Other (Topic 350) (ASU 2011-08), permitting entities the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. ASU No. 2011- 08 was effective for the Company January 1, 2012 and the adoption had no effect on our financial position, results of operations or cash flows. In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220)-Presentation of Comprehensive Income, to increase the prominence of items reported in other comprehensive income and to facilitate convergence of U.S. GAAP and IFRS. This amendment requires that all nonowner changes in equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendment therefore eliminates the option to present components of other comprehensive income as part of the statement of changes in equity. This amendment does not change the items reported under other comprehensive income, it does not change when an item of other comprehensive income must be reclassified to net income and entities can choose to show line items net of tax effects or show one amount of aggregate income tax expense or benefit. This amendment must be applied retrospectively and for public entities, these amendments become effective for interim and fiscal periods beginning after December 15, 2011. We comply with the provisions of this amendment by using the two statement approach.
