Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	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.
