Accounting Standards Update 2014-09 [Member]
Company And Summary Of Significant Accounting Policies [Line Items]
Description of new accounting pronouncements			In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to a customer. This guidance will replace most existing revenue recognition guidance and will be effective for the Company beginning in fiscal year 2019, including interim periods within that reporting period, based on the FASB decision in July 2015 (ASU 2015-14, Revenue from Contracts with Customers – Deferral of the Effective Date) to delay the effective date of the new revenue recognition standard by one year, but providing entities a choice to adopt the standard as of the original effective date. The standard permits the use of either the retrospective or cumulative effect transition method. The Company has not selected a transition method and the Company is currently evaluating the impact this standard will have on its consolidated financial statements and disclosures.

Description of new accounting pronouncements			In April 2015, the FASB issued ASU 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. ASU 2015-05 is effective for the Company in fiscal year 2017 with early adoption permitted using either of two methods: (i) prospectively to all arrangements entered into or materially modified after the effective date and represent a change in accounting principle; or (ii) retrospectively. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

Description of new accounting pronouncements			In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 limits the requirement to report discontinued operations to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. The amendments also require expanded disclosures concerning discontinued operations and disclosures of certain financial results attributable to a disposal of a significant component of an entity that does not qualify for discontinued operations reporting. This guidance became effective for the Company beginning in the first quarter of fiscal year 2016 and the authoritative guidance did not have a material impact on the Company’s consolidated financial statements and disclosures.

Description of new accounting pronouncements			In August 2015, the FASB issued ASU 2015-15, Interest – Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. ASU 2015-15 provides additional guidance to ASU 2015-03, which did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. ASU 2015-15 noted that staff of the Securities and Exchange Commission (the SEC) would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. This new guidance will be effective for the Company in fiscal year 2017, with early adoption permitted. The new guidance shall be applied on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements and disclosures.

Description of new accounting pronouncements			In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. Under current GAAP, the acquirer is required to retrospectively apply adjustments made to provisional amounts recognized in a business combination. The new standard should be applied prospectively and will become effective for the Company in fiscal year 2017, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements and disclosures.
