Accounting Policies [Abstract]
New Accounting Pronouncements, Policy	New Accounting Pronouncements or Updates Recently Adopted In April 2014, the Financial Accounting Standards Board (“FASB”) issued an update to Accounting Standards Codification (“ASC”) 205, Presentation of Financial Statements, and ASC 360, Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. Under this update, a discontinued operation may include a component of an entity or a group of components of an entity, a business, or nonprofit activity. Only those disposals of components of an entity that represent a strategic shift that has, or will have, a major effect on an entity’s operations and financial results will be reported as discontinued operations in the financial statements. This update should be applied prospectively. The Company adopted this update in the first quarter of fiscal year 2016. There was no material impact on the Company’s financial position, results of operations, or cash flows. In April 2015, the FASB issued an update to ASC 835, Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. Under this update, debt issuance costs are required to be presented as a direct deduction from the carrying amount of the related debt liability, consistent with the presentation of debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this update. This update should be applied retrospectively to all prior periods presented in the financial statements. The Company adopted this update in the first quarter of fiscal year 2016. There was no material impact on the Company’s financial position, results of operations, or cash flows. In September 2015, the FASB issued an update to ASC 805, Business Combinations: Simplifying the Accounting Measurement-Period Adjustments. This update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. Under this update, the adjustments are recognized in the reporting period in which the adjustment amounts are determined. This update should be applied prospectively. The Company adopted this update in the first quarter of fiscal year 2016. There was no material impact on the Company’s financial position, results of operations, or cash flows. In November 2015, the FASB issued an update to ASC 740, Income Taxes: Balance Sheet Classification of Deferred Taxes. This update simplifies the presentation of current and non-current deferred tax liabilities and assets. Under this update, the deferred tax liabilities and assets are classified as non-current on the balance sheet. The update does not impact the current requirement that deferred tax liabilities and assets be offset and presented as a single amount. This update may be applied either prospectively or retrospectively. The Company adopted this update in the first quarter of fiscal year 2016 and has elected to apply this update prospectively. There was no material impact on the Company’s financial position, results of operations, or cash flows. Recent Accounting Pronouncements or Updates That Are Not Yet Effective In May 2014, the FASB issued ASC 606, Revenue from Contracts with Customers, that will supersede virtually all existing revenue guidance. Under this new revenue guidance, an entity is required to recognize revenue upon transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. As such, an entity will need to use more judgment and make more estimates than under the current guidance. This new revenue guidance should be applied retrospectively either to each prior reporting period presented in the financial statements, or only to the most current reporting period presented in the financial statements with a cumulative effect adjustment recorded in retained earnings. In August 2015, the FASB issued an update to defer the effective date of this new revenue guidance by one year. This new revenue guidance becomes effective and will be adopted by the Company in the first quarter of fiscal year 2019. Early adoption is not permitted for reporting periods before the first quarter of fiscal year 2018. The Company is currently evaluating the impact of this new revenue guidance on its consolidated financial statements. In March 2016, the FASB issued an update to ASC 606, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies the implementation guidance for principal versus agent considerations. In April 2016, the FASB issued an update to ASC 606, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing, which clarifies the guidance related to identifying performance obligations and accounting for licenses of intellectual property. In May 2016, the FASB issued an update to ASC 606, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients, which clarifies the guidance related to collectibility and non-cash consideration, as well as provides practical expedients for the transition to ASC 606. The Company must adopt these updates with the adoption of ASC 606, Revenue from Contracts with Customers. The Company is currently evaluating the impact of these updates on its consolidated financial statements. In April 2015, the FASB issued an update to ASC 350, Intangibles—Goodwill and Other—Internal-Use Software: Customer’s Accounting for Fees Paid in Cloud Computing Arrangement. This update provides guidance on the accounting for fees paid in a cloud computing arrangement if the arrangement was determined to include a software license. This update will not change U.S. GAAP for a customer’s accounting for service contracts. This update may be applied either prospectively or retrospectively and will be adopted by the Company in the first quarter of fiscal year 2017. Early adoption is permitted. The Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. In July 2015, the FASB issued an update to ASC 330, Inventory: Simplifying the Measurement of Inventory. Under this update, measurement of inventory is based on the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated cost of completion and disposal. This update does not apply to inventory that is measured using last-in, first-out or the retail inventory method. This update should be applied prospectively and will be adopted by the Company in the first quarter of fiscal year 2018. Early adoption is permitted. The Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. In January 2016, the FASB issued an update to ASC 825, Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. This update consists of eight provisions that provide guidance on the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. This update should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption and prospectively for equity investments without readily determinable fair values. This update becomes effective and will be adopted by the Company in the first quarter of fiscal year 2019. Early adoption is permitted for two of the eight provisions. The Company is currently evaluating the impact of this update on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASC 842, Leases, that will supersede the existing lease guidance, including on-balance sheet recognition of operating leases for lessees. This new lease guidance should be applied using a modified retrospective approach and will be adopted by the Company in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is currently evaluating the impact of this new lease guidance on its consolidated financial statements. In March 2016, the FASB issued an update to ASC 718, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting. This update simplifies certain aspects of the accounting for share-based payment transactions, including income taxes, forfeiture rates, classification of awards, and classification in the statement of cash flows. This update becomes effective in the first quarter of fiscal year 2018. Early adoption is permitted, and the Company plans to adopt this update before the effective date. The Company is currently evaluating the impact of this update on its consolidated financial statements.
