Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	NOTE 2 — RECENT ACCOUNTING PRONOUNCEMENTS In May 2011, the Financial Accounting Standards Board ("FASB") issued amendments to its accounting guidance on fair value measurement. The amendments provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. The amendments change certain fair value measurement principles and enhance the disclosure requirements about fair value measurements. This guidance is effective during interim and annual periods beginning after December 15, 2011 and should be applied prospectively. There was no material impact from our adoption of this guidance to our consolidated financial statements. In June 2011, the FASB issued amendments to its accounting guidance on comprehensive income. The amendments require 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. The amendments eliminate the option to present the components of other comprehensive income as part of the statement of equity. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We have presented separate consolidated statements of comprehensive income consecutively after the consolidated income statements upon adoption of this guidance. In December 2011, the FASB issued amendments to defer the presentation on the face of the financial statements the reclassification adjustments out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented. In September 2011, the FASB issued amendments to its accounting guidance on testing goodwill for impairment. The amendments allow entities to use a qualitative approach to test goodwill for impairment. This permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that it is more likely than not that the fair value of a reporting unit is less than its carrying value, it is necessary to perform the currently prescribed two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. This guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. There was no impact from our adoption of this guidance to our consolidated financial statements. In December 2011, the FASB issued amendments to disclosures about offsetting assets and liabilities. The amendments require the disclosure of 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. This guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The disclosures required by the amendments should be provided retrospectively for all comparative periods presented. We do not anticipate any impact from our adoption of this guidance to our consolidated financial statements as these amendments only refer to enhanced disclosures.
