| New Accounting Pronouncements                           | New Accounting PronouncementsIn May 2014, the Financial Accounting Standards Board ("FASB") issued guidance outlining a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers that supersedes most current revenue recognition guidance.  This guidance requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  Additionally, this guidance expands related disclosure requirements.  The effective date of these revisions is for reporting periods beginning after December 15, 2016, with early application not permitted.  The Company is evaluating the impact of this revision.In June 2014, the FASB issued guidance related to accounting for share-based payments for certain performance stock awards.   The effective date of this guidance is for reporting periods beginning after December 15, 2015, with early adoption permitted.    The Company is evaluating the impact of this guidance.In August 2014, the Financial Accounting Standards Board (FASB) issued guidance regarding management's going concern evaluations. The guidance requires management to evaluate, at each interim and annual reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued, and provide related disclosures. The guidance is effective for all entities for annual periods ending after December 15, 2016, and for annual and interim periods thereafter, and early adoption is permitted. We do not believe the standard will have a material impact on our financial statement disclosures. |
