Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Pronouncements Not Yet Adopted In January 2014, the Financial Accounting Standards Board (“FASB”) issued guidance related to service concession arrangements. A service concession arrangement is an arrangement between a public-sector entity grantor and an operating entity under which the operating entity operates the grantor's infrastructure (for example, airports, roads and bridges). The guidance states that service concession arrangements should not be accounted for under the guidance of Topic 840, Leases, but rather other guidance as deemed appropriate. This guidance is effective for fiscal years beginning December 15, 2014. We are currently evaluating the impact of the guidance on our financial condition and results of operations. In July 2013, the FASB issued guidance on the financial statement presentation of an unrecognized tax benefit. The guidance requires that an unrecognized tax benefit or a portion of an unrecognized tax benefit, be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. If an applicable deferred tax asset is not available or a company does not expect to use the applicable deferred tax asset, the unrecognized tax benefit should be presented in an entity's financial statements as a liability and should not be combined with a deferred tax asset. This guidance is effective for fiscal years beginning after December 15, 2013. The adoption of this guidance is not expected to have a material impact on our financial condition or results of operations. In March 2013, the FASB issued guidance on the release of a cumulative translation adjustment ("CTA") related to an entity's investment in a foreign entity into income. The guidance requires such CTA to be released when there has been a: (1) sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity, (2) loss of a controlling financial interest in an investment in a foreign entity or (3) step acquisition for a foreign entity. This guidance is effective for fiscal years beginning after December 15, 2013. The impact of the guidance on our financial condition and results of operations will depend on the occurrence and the significance of transactions that meet the criteria described above. In February 2013, the FASB issued guidance related to the measurement and disclosure of obligations resulting from joint and several liability arrangements. The new guidance requires companies to measure obligations resulting from joint and several liability arrangements as the sum of (1) the amount the company agreed to pay on the basis of its arrangement among co-obligors and (2) any additional amount the company expects to pay on behalf of its co-obligors. Additionally, the new guidance requires the disclosure of a description of the joint and several arrangement and the total outstanding amount of the obligation for all joint parties. This guidance is effective for fiscal years beginning after December 15, 2013. The adoption of this guidance is not expected to have a material impact on our financial condition or results of operations. Recently Adopted Pronouncements In February 2013, the FASB issued guidance regarding new disclosures for items reclassified out of accumulated other comprehensive income ("AOCI"). The guidance requires entities to present information about items reclassified out of AOCI by component. Additionally, entities are required to present either on the face of the statement where net income is presented or as a separate disclosure in the notes to the financial statements, significant amounts reclassified out of AOCI by the respective line items of net income. This guidance is effective for fiscal years beginning after December 15, 2012. The adoption of this guidance did not have a material impact on our financial statement presentation and disclosures. In July 2012, the FASB provided companies with the option to make an initial qualitative evaluation, based on events and circumstances, to determine the likelihood of an impairment of an indefinite-lived intangible asset. The results of this qualitative assessment determine whether it is necessary to perform the currently required quantitative comparison of the indefinite-lived intangible asset's fair value to its carrying amount. If it is more likely than not that the fair value of the intangible asset is less than its carrying amount, a company would be required to perform the quantitative assessment. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 with early adoption permitted. The adoption of the guidance did not have a material impact on our financial condition and results of operations. In September 2011, in conjunction with the assessment of the impairment of goodwill, the FASB provided companies with the option to make an initial qualitative evaluation, based on the entity’s events and circumstances, to determine the likelihood of goodwill impairment. The results of this qualitative assessment determine whether it is necessary to perform the currently required two-step impairment test. If it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a company would be required to perform the two-step impairment test. We adopted this new guidance effective January 1, 2012. The adoption of this guidance did not have a material impact on our financial condition and results of operations. In June 2011, the FASB issued authoritative guidance surrounding the presentation of comprehensive income, with an objective of increasing the prominence of items reported in other comprehensive income (“OCI”). The guidance requires most entities to present items of net income and other comprehensive income either in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive, statements of net income and other comprehensive income. We have adopted this guidance with retrospective application and have presented total comprehensive income in our Consolidated and Combined Statements of Comprehensive Income for all reported periods. In May 2011, the FASB issued guidance intended to achieve common fair value measurements and related disclosures between U.S. GAAP and international accounting standards. The amendments primarily clarify existing fair value guidance and are not intended to change the application of existing fair value measurement guidance. However, the amendments include certain instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. On January 1, 2012, we adopted this guidance. The adoption of the guidance did not have a material impact on our financial condition and results of operations.
