Derivative Instruments and Hedging Activities [Abstract]
Derivative Instruments and Hedging Activities	Note 14 — 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 Balance Sheets. 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 We had $633.5 million of variable rate loans outstanding at January 31, 2019, which approximated fair value. As of January 31, 2019 and 2018 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. 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, we pay a fixed rate of 0.92% 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 May 15, 2019. As of January 31, 2019 and April 30, 2018, the notional amount of the interest rate swap was $350.0 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. 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 January 31, 2019 and April 30, 2018 was a deferred gain of $1.8 million and $5.1 million, respectively. Based on the maturity dates of the contracts, the entire deferred gain as of January 31, 2019 was recorded within Prepaid Expenses and Other Current Assets and as of April 30, 2018 was recorded within Other Non-Current Assets. The pre-tax gains that were reclassified from Accumulated Other Comprehensive Loss into Interest Expense for the three months ended January 31, 2019 and 2018 were $1.3 million and $0.4 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 nine months ended January 31, 2019 and 2018 were $3.4 million and $0.8 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) Gains 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) Gains in the Unaudited Condensed Consolidated Statements of Income. As of January 31, 2019, and April 30, 2018, we did not maintain any open forward exchange contracts. In addition, we did not maintain any open forward contracts during the nine months ended January 31, 2019 and 2018.

Note 14 — 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 Balance Sheets.
