Derivative Instruments and Hedging Activities [Abstract]
Derivative Instruments and Hedging Activities	Note 16 — Derivative Instruments and Hedging 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 on our Unaudited Condensed Consolidated Statements of Financial Position. 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 October 31, 2019, we had total debt outstanding of $794.7 million, net of unamortized issuance costs of $0.8 million of which $795.5 million are variable rate loans outstanding under the Amended and Restated RCA, which approximated fair value. 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 three-year period ending August 15, 2022. As of October 31, 2019, 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 three-year period ending July 15, 2022. As of October 31, 2019, the notional amount of the interest rate swap was $100.0 million. 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 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 0.92% 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. As of October 31, 2019 and April 30, 2019, the interest rate swap agreements maintained by us were designated as cash flow hedges as defined under ASC 815 “Derivatives and Hedging.” As a result, there was no impact on our Unaudited Condensed Consolidated Statements of Income for 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. 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 October 31, 2019 and April 30, 2019 was a deferred loss of $0.7 million and a deferred gain of $0.5 million, respectively. Based on the maturity dates of the contracts, the entire deferred loss as of October 31, 2019 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 into Interest Expense for the three months ended October 31, 2019 and 2018 were $0.3 million and $1.1 million, respectively. The pre-tax gains that were reclassified from Accumulated Other Compensation Loss into Interest Expense in the Unaudited Condensed Consolidated Statements of Income for the six months ended October 31, 2019 and 2018 were $0.5 million and $2.0 million, respectively. 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 Losses in the Unaudited Condensed Consolidated Statements of Income and carried at their fair value in the Unaudited Condensed 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 Losses in the Unaudited Condensed Consolidated Statements of Income. As of October 31, 2019, and April 30, 2019, we did not maintain any open forward exchange contracts. In addition, we did not maintain any open forward contracts during the three and six months ended October 31, 2019 and 2018.
