Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	In May 2014, the FASB issued ASU 2014-9, “Revenue from Contracts with Customers (Topic 606).” This guidance requires an entity to recognize revenue to depict the transfer of 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. In August 2015, this guidance was amended deferring the effective date to annual reporting periods beginning after December 15, 2017. The Company will adopt this standard in fiscal year 2019. The Company has not yet determined the effect, if any, that the adoption of this standard will have on the Company’s financial position or results of operations. In November 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-17, “Income Taxes (Topic 740) – Balance Sheet Classification of Deferred Taxes.” This guidance eliminates the requirement to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. Instead, the update requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early adoption permitted prospectively or retrospectively. The Company early adopted this guidance prospectively beginning with the Consolidated Balance Sheet at April 30, 2016. Prior periods were not retrospectively adjusted. In April 2015, the FASB issued ASU 2015-03, “Interest (Topic 835) – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.” This guidance requires that debt issuance costs related to a recognized liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. The Company adopted this standard effective May 1, 2016. The adoption of this standard did not have a significant impact on the Company’s consolidated financial position or results of operations.
