| New Accounting Pronouncements                                                     | New Accounting Pronouncements Reporting discontinued operations and disclosures of disposals of components of an entity – In April 2014, the Financial Accounting Standards Board (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 was effective January 1, 2015 and did not 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.Variable interest entities – In February 2015, the FASB issued accounting guidance on the consolidation of VIEs.  The new guidance revises previous guidance by establishing an analysis for determining whether a limited partnership or similar entity is a VIE and whether outsourced decision-maker fees are considered variable interests.  In addition, the new guidance revises how a reporting entity evaluates economics and related parties when assessing who should consolidate a VIE.  This guidance is effective January 1, 2016.  We do not expect the adoption to have a material impact on our financial statements.Presentation of debt issuance costs – In April 2015, the FASB issued accounting guidance which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability.  Prior to the issuance of the standard, debt issuance costs were required to be presented in the balance sheet as an asset.  This guidance is effective January 1, 2016.  We do not expect the adoption to have a material impact on our financial statements. |
