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 sales and 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 October 31, 2021, we had total debt outstanding of $1,045.0 million, net of unamortized issuance costs of $0.4 million of which $1,045.4 million are variable rate loans outstanding under the Amended and Restated RCA, which approximated fair value. We had outstanding interest rate swap agreements with combined notional amounts of $400.0 million as of October 31, 2021 and April 30, 2021. These agreements were accounted for as cash flow hedges which fixed a portion of the variable interest due on our Amended and Restated RCA. 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, 2021 was a deferred loss of $3.2 million and a deferred gain of $0.7 million. Based on the maturity dates of the contracts, $2.1 million of the deferred loss as of October 31, 2021 was recorded within Other accrued liabilities and $1.1 million of the deferred loss was recorded within Other long-term liabilities. The deferred gain was recorded within Other non-current assets. The fair value of the interest rate swaps as of April 30, 2021 was a deferred loss of $5.6 million. Based on the maturity dates of the contracts, the entire deferred loss as of April 30, 2021 was recorded within Other long-term liabilities. The pretax losses that were reclassified from Accumulated other comprehensive loss into Interest expense for the three and six months ended October 31, 2021 were $1.1 million and $2.2 million, respectively. The pretax losses that were reclassified from Accumulated other comprehensive loss into Interest expense for the three and six months ended October 31, 2020 were $0.9 million and $1.8 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 on our Unaudited Condensed Consolidated Statements of Net Income and carried at fair value on our 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 on our Unaudited Condensed Consolidated Statements of Net Income. As of October 31, 2021, and April 30, 2021, we did not maintain any open forward exchange contracts. In addition, we did not maintain any open forward contracts during the six months ended October 31, 2021 and 2020.
