New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Adoption of New Accounting Pronouncements Joint and Several Liability Arrangements In February 2013, the FASB issued authoritative guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. The guidance was effective for our quarter ended March 31, 2014. The adoption of this guidance did not have an impact on our financial position or results from operations. Cumulative Translation Adjustment In March 2013, the FASB issued authoritative guidance on a parent's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. This update also resolves the diversity in practice for the treatment of business combinations achieved in stages (sometimes also referred to as step acquisitions) involving a foreign entity. The guidance was effective for our quarter ended March 31, 2014. The adoption of this guidance did not have an impact on our financial position or results from operations. Liquidation Basis of Accounting In April 2013, the FASB issued authoritative guidance to clarify when it is appropriate to apply the liquidation basis of accounting. Additionally, the update provides guidance for recognition and measurement of assets and liabilities and requirements for financial statements prepared using the liquidation basis of accounting. Under the amendment, entities are required to prepare their financial statements under the liquidation basis of accounting when a liquidation becomes imminent. The guidance was effective for our quarter ended March 31, 2014. The adoption of this guidance did not have an impact on our financial position or results from operations. Presentation of Unrecognized Tax Benefits In July 2013, the FASB issued authoritative guidance related to the presentation of unrecognized tax benefits. The update requires that the entity present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward in the statement of financial position. The guidance does not apply to the extent that a net operating loss carryforward or tax credit carryforward at the reporting date is not available under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position. The guidance was effective for our quarter ended March 31, 2014. As a result of adopting this guidance, we have presented deferred tax assets net of unrecognized tax benefits, as appropriate, in the consolidated balance sheets. The adoption of this guidance impacted the classification of our outstanding unrecognized tax benefits and resulted in a reclassification of $37.8 million from the unrecognized tax benefits line item within the consolidated balance sheet upon adoption in the first quarter of 2014. New Accounting Pronouncements Not Yet Adopted Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity In April 2014, the FASB issued authoritative guidance related to reporting discontinued operations and disclosures of disposals of components of an entity. The update limits discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity's operations and financial results. This update requires expanded disclosures related to assets, liabilities, revenues and expenses of discontinued operations. This update also requires the disclosure of pretax profit or loss and the financial effects of significant disposals that do not qualify for discontinued operations reporting. The guidance is effective for annual reporting periods beginning on or after December 15, 2014, and interim reporting periods thereafter. We do not anticipate that this guidance will have an impact on our financial position or results of operations. Revenue Recognition In May 2014, the FASB issued authoritative guidance related to new accounting requirements for the recognition of revenue from contracts with customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for the goods or services. The requirements of the new standard are effective for the annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. We are currently evaluating the potential impact on our financial position and results of operations upon adoption of this guidance. Share-Based Payments In June 2014, the FASB issued authoritative guidance related to share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The requirements of the new standard are effective for the annual reporting periods beginning after December 15, 2015, and interim periods within those annual periods. We do not anticipate that this guidance will have a material impact on our financial position or results of operations.
