Derivative Instruments and Activities [Abstract]
Derivative Instruments and Activities	Note 15 – Derivative Instruments and Activities From time-to-time, we enter into forward exchange and interest rate swap contracts as a hedge against foreign currency asset and liability commitments, changes in interest rates, and anticipated transaction exposures, including intercompany purchases. All derivatives are recognized as assets or liabilities and measured at fair value. Derivatives that are not determined to be effective hedges are adjusted to fair value with a corresponding adjustment to earnings. We do not use financial instruments for trading or speculative purposes. Interest Rate Contracts As of April 30, 2020, we had total debt outstanding of $775.1 million, net of unamortized issuance costs of $0.7 million of which $775.8 million are variable rate loans outstanding under the Amended and Restated RCA, which approximated fair value. As of April 30, 2020 and 2019, the interest rate swap agreements we maintained were designated as fully effective cash flow hedges as defined under Accounting Standards Codification 815 “Derivatives and Hedging” ("ASC 815"). As a result, there was no impact on our Consolidated Statements of (Loss) Income from changes in the fair value of the interest rate swaps, as they were fully offset by changes in the interest expense on the underlying variable rate debt instruments. Under ASC 815, derivative instruments that are designated as cash flow hedges have changes in their fair value recorded initially within Accumulated Other Comprehensive Loss on the Consolidated Statements of Financial Position. As interest expense is recognized based on the variable rate loan agreements, the corresponding deferred gain or loss on the interest rate swaps is reclassified from Accumulated Other Comprehensive Loss to Interest Expense on the Consolidated Statements of (Loss) Income. It is management’s intention that the notional amount of interest rate swaps be less than the variable rate loans outstanding during the life of the derivatives. On February 26, 2020 we entered into two forward starting interest rate swap agreements, which fixed a portion of the variable interest due on our Amended and Restated RCA. Under the terms of the agreement, we pay a fixed rate of 1.150% and receive a variable rate of interest based on one-month LIBOR from the counterparty which is reset every month for a 3-year period ending March 15, 2023. As of April 30, 2020, the notional amount of the interest rate swaps was $100.0 million. On August 7, 2019 we entered into a forward starting interest rate swap agreement, which fixed a portion of the variable interest due on our Amended and Restated RCA. Under the terms of the agreement, we pay a fixed rate of 1.400% and receive a variable rate of interest based on one-month LIBOR from the counterparty which is reset every month for a 3-year period ending August 15, 2022. As of April 30, 2020, the notional amount of the interest rate swap was $100.0 million. On June 24, 2019 we entered into a forward starting interest rate swap agreement, which fixed a portion of the variable interest due on our Amended and Restated RCA. Under the terms of the agreement, we pay a fixed rate of 1.650% and receive a variable rate of interest based on one-month LIBOR from the counterparty which is reset every month for a 3-year period ending July 15, 2022. As of April 30, 2020, the notional amount of the interest rate swap was $100.0 million. On April 4, 2016, we entered into a forward starting interest rate swap agreement which fixed a portion of the variable interest due on a variable rate debt renewal on May 16, 2016. Under the terms of the agreement, which expired on May 15, 2019, we paid a fixed rate of 0.920% and receive a variable rate of interest based on one-month LIBOR from the counterparty which was reset every month for a three-year period ending May 15, 2019. Prior to expiration, the notional amount of the interest rate swap was $350.0 million. We record the fair value of our interest rate swaps on a recurring basis using Level 2 inputs of quoted prices for similar assets or liabilities in active markets. The fair value of the interest rate swaps as of April 30, 2020 and 2019, was a deferred loss of $8.3 million and a deferred gain of $0.5 million, respectively. Based on the maturity dates of the contracts, the entire deferred loss as of April 30, 2020 was recorded within Other Long-Term Liabilities and the entire deferred gain as of April 30, 2019 was recorded within Prepaid Expenses and Other Current Assets. The pre-tax gains that were reclassified from Accumulated Other Comprehensive Loss to Interest Expense for the years ended April 30, 2020, 2019, and 2018 were $0.4 million, $4.7 million, and $1.5 million, respectively. Based on the amount in Accumulated Other Comprehensive Loss at April 30, 2020, approximately $2.7 million, net of tax, would be reclassified into net income in the next twelve months. Foreign Currency Contracts We may enter into forward exchange contracts to manage our exposure on certain foreign currency denominated assets and liabilities. The forward exchange contracts are marked to market through Foreign Exchange Transaction Gains (Losses) on the Consolidated Statements of (Loss) Income and carried at their fair value on the Consolidated Statements of Financial Position. Foreign currency denominated assets and liabilities are remeasured at spot rates in effect on the balance sheet date, with the effects of changes in spot rates reported in Foreign Exchange Transaction Gains (Losses) on the Consolidated Statements of (Loss) Income. As of April 30, 2020 and 2019, we did not maintain any open forward contracts. In addition, we did not maintain any open forward contracts during the years ended April 30, 2020, 2019 and 2018.
