Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of presentation — Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. These statements are unaudited, but in the opinion of management include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the results for the interim periods. The results reported in these consolidated financial statements should not necessarily be taken as indicative of results that may be expected for the entire year. The financial information included herein should be read in conjunction with the consolidated financial statements in Item 8 of our 2012 Form 10-K.

Discontinued Operations

Discontinued operations — We classify a business component that has been disposed of or classified as held for sale as discontinued operations if the cash flows of the component have been or will be eliminated from our ongoing operations and we will no longer have any significant continuing involvement in or with the component. The results of operations of our discontinued operations, including any gains or losses on disposition, are aggregated and presented on one line in the consolidated statement of operations. See Note 3 for additional information regarding our discontinued operations.

In December 2011, the Financial Accounting Standards Board (FASB) issued guidance to enhance disclosures about offsetting assets and liabilities. 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. The guidance was effective January 1, 2013. The adoption of this guidance did not impact our financial condition or results of operations.

In March 2013, the FASB issued guidance to clarify existing requirements for the release - the recognition of an amount in the income statement - of the cumulative translation adjustment. The guidance applies to the release of cumulative translation adjustment when an entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. It also applies to the release of the cumulative translation adjustment when there is a loss of a controlling financial interest in a foreign entity or a step acquisition involving an equity method investment that is a foreign entity. The accounting for the financial interest within a foreign entity is the same regardless of the form of the transaction. The guidance will be applied to relevant transactions that occur on or after January 1, 2014. The impact related to this guidance is not presently determinable.

In February 2013, the FASB issued guidance related to obligations resulting from joint and several liability arrangements where the amount of the obligation is fixed at the reporting date. Obligations within scope include certain debt arrangements and settled litigation but not contingencies, guarantees, retirement benefits or income taxes. The guidance, which is effective January 1, 2014, is not expected to impact our financial condition or results of operations.

In July 2012, the FASB issued guidance to provide an option in a company's annual indefinite-lived intangible asset impairment test to first assess qualitative factors to determine whether the existence of events and circumstances indicate that it is more likely than not that an asset is impaired. If, after assessing all events and circumstances, it is determined that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. The changes are effective for annual and interim impairment tests performed after January 1, 2013. Adoption of this guidance will not impact our financial condition or results of operations.
