Derivative Instruments and Activities [Abstract]
Derivative Instruments and Activities	Note 14 – 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: We had $478.8 million of variable rate loans outstanding at April 30, 2019, which approximated fair value. As of April 30, 2019 and 2018, 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 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 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 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 will pay a fixed rate of 0.92% and receive a variable rate of interest based on one-month LIBOR (as defined) from the counterparty which is reset every month for a three-year period starting May 16, 2016, ending May 15, 2019. As of April 30, 2019, 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, 2019 and 2018, was a deferred gain of $0.5 million and $5.1 million, respectively. Based on the maturity dates of the contracts, the entire deferred gain as of April 30, 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) losses that were reclassified from Accumulated Other Comprehensive Loss to Interest Expense for the years ended April 30, 2019, 2018, and 2017 were $(4.7) million, $(1.5) million, and $1.1 million, respectively. Based on the amount in Accumulated Other Comprehensive Loss at April 30, 2019, approximately $0.2 million, net of tax, of unrecognized gains 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 (Losses) Gains on the Consolidated Statements of 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 (Losses) Gains on the Consolidated Statements of Income. As of April 30, 2019 and 2018, we did not maintain any open forward contracts. In addition, we did not maintain any open forward contracts during the years ended April 30, 2019 and 2018. As of April 30, 2017, we did not maintain any open forward contracts, but we did have open forward contracts during the year ended April 30, 2017. There were two open forward exchange contracts with notional amounts of 31 million euros and 274 million pounds sterling to manage foreign currency exposures on intercompany loans. These contracts matured in May 2016 and February 2017, respectively. For the year ended April 30, 2017, the gains recognized on forward contracts were $59.0 million.

Note 14 – 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:

We had $478.8 million of variable rate loans outstanding at April 30, 2019, which approximated fair value.

As of April 30, 2019 and 2018, 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 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 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 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 will pay a fixed rate of 0.92% and receive a variable rate of interest based on one-month LIBOR (as defined) from the counterparty which is reset every month for a three-year period starting May 16, 2016, ending May 15, 2019. As of April 30, 2019, 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, 2019 and 2018, was a deferred gain of $0.5 million and $5.1 million, respectively. Based on the maturity dates of the contracts, the entire deferred gain as of April 30, 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) losses that were reclassified from Accumulated Other Comprehensive Loss to Interest Expense for the years ended April 30, 2019, 2018, and 2017 were $(4.7) million, $(1.5) million, and $1.1 million, respectively. Based on the amount in Accumulated Other Comprehensive Loss at April 30, 2019, approximately $0.2 million, net of tax, of unrecognized gains 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 (Losses) Gains on the Consolidated Statements of 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 (Losses) Gains on the Consolidated Statements of Income.

As of April 30, 2019 and 2018, we did not maintain any open forward contracts. In addition, we did not maintain any open forward contracts during the years ended April 30, 2019 and 2018.

As of April 30, 2017, we did not maintain any open forward contracts, but we did have open forward contracts during the year ended April 30, 2017. There were two open forward exchange contracts with notional amounts of 31 million euros and 274 million pounds sterling to manage foreign currency exposures on intercompany loans. These contracts matured in May 2016 and February 2017, respectively. For the year ended April 30, 2017, the gains recognized on forward contracts were $59.0 million.
