Organization Consolidation And Presentation Of Financial Statements [Abstract]
Recent Accounting Pronouncements	In April 2014, the Financial Accounting Standards Board (FASB) issued guidance that modifies the criteria used to qualify divestitures for classification as discontinued operations and expands disclosure related to disposals of significant components. The amendment will become effective for the Company in fiscal 2016, with early adoption permitted; however, the Company does not expect to early adopt the amended guidance. The amended guidance is expected to decrease the likelihood that future disposals will qualify for discontinued operations treatment, meaning that the results of operation of some future disposals may be reported as continuing operations. In May 2014, FASB amended requirements for an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is permitted. The updated standard becomes effective for the Company in the first fiscal quarter of 2019. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on consolidated financial statements and related disclosures. In April 2015, FASB amended requirements related to the presentation of debt issuance costs. The updated standard requires debt issuance costs related to recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. The recognition and measurement of debt issuance costs are not affected by this amendment. The updated standard is effective for the Company in the first fiscal quarter of 2016. The Company does not expect that the standard will have a material impact on its consolidated financial statements and related disclosures.
