| New Accounting Pronouncements                                                     | New Accounting Pronouncements Joint and several liability arrangements – In February 2013,the Financial Accounting Standards Board (FASB) issued accounting guidance on the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements.  The guidance requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors.  The entity is also required to disclose the nature and amount of the obligation as well as any other information about those obligations.  This guidance was effective January 1, 2014, with retrospective application required.  The guidance did not have a material impact on our financial statements.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 – In March 2013, the FASB issued accounting guidance on the parent's accounting for the cumulative translation adjustment (CTA) upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity.  The new standard clarifies existing guidance regarding when the CTA should be released into earnings upon various deconsolidation and consolidation transactions.  The guidance was effective January 1, 2014.  The guidance did not have a material impact on our financial statements.Presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists – In July 2013, the FASB issued accounting guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists.  The guidance requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to 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 in the financial statements if available under the applicable tax jurisdiction.  The guidance was effective January 1, 2014.  The guidance did not have a material impact on our financial statements.Reporting discontinued operations and disclosures of disposals of components of an entity – In April 2014, the FASB  issued accounting guidance for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements.  The guidance defines a discontinued operation as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results.  This guidance is effective January 1, 2015.  We do not expect the adoption to have a material impact on our financial statements.Revenue recognition – In May 2014, the  FASB issued new revenue recognition guidance to provide a single, comprehensive revenue recognition model for all contracts with customers.  Under the new guidance, an entity will recognize revenue to depict the transfer of promised goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services.  A five step model has been introduced for an entity to apply when recognizing revenue.  The new guidance also includes enhanced disclosure requirements and is effective January 1, 2017.  Entities have the option to apply the new guidance under a retrospective approach to each prior reporting period presented, or a modified retrospective approach with the cumulative effect of initially applying the new guidance recognized at the date of initial application within the Consolidated Statement of Changes in Stockholder's Equity.  We are in the process of evaluating the application and implementation of the new guidance. |
