Debt and Available Credit Facilities [Abstract]
Debt and Available Credit Facilities	Note 13 – Debt and Available Credit Facilities As of April 30, 2019 and 2018, our debt of $478.8 million and $360.0 million, respectively, consisted of amounts due under our revolving credit facilities. We have a revolving credit agreement (“RCA”) with a syndicated bank group led by Bank of America. The RCA consists of a $1.1 billion five-year senior revolving credit facility payable March 1, 2021. Under the RCA, which can be drawn in multiple currencies, we have the option of borrowing at the following floating interest rates: (i) at a rate based on the London Interbank Offered Rate (“LIBOR”) plus an applicable margin ranging from 0.98% to 1.50%, depending on our consolidated leverage ratio, as defined, or (ii) for U.S. dollar-denominated loans only, at the lender’s base rate plus an applicable margin ranging from zero to 0.45%, depending on our consolidated leverage ratio. The lender’s base rate is defined as the highest of (i) the U.S. federal funds effective rate plus a 0.50% margin, (ii) the Eurocurrency rate, as defined, plus a 1.00% margin, or (iii) the Bank of America prime lending rate. In addition, we pay a facility fee ranging from 0.15% to 0.25% depending on our consolidated leverage ratio. We also have the option to request an additional credit limit increase of up to $350 million in minimum increments of $50 million, subject to the approval of the lenders. The RCA contains certain restrictive covenants related to our consolidated leverage ratio and interest coverage ratio, which we were in compliance with as of April 30, 2019 and 2018. Due to the fact that there are no principal payments due until the end of the agreement in the year ended April 30, 2021, we have classified our entire debt obligation as long-term as of April 30, 2019 and 2018. We have other lines of credit aggregating $2.7 million at various interest rates. There were no outstanding borrowings under these credit lines at April 30, 2019 and 2018. Our total available lines of credit as of April 30, 2019, were approximately $1.1 billion, of which approximately $0.6 billion was unused. The weighted average interest rates on total debt outstanding during the years ended April 30, 2019 and 2018 were 2.69% and 2.44%, respectively. As of April 30, 2019 and 2018, the weighted average interest rates for total debt were 2.88% and 2.58%, respectively. Based on estimates of interest rates currently available to us for loans with similar terms and maturities, the fair value of our debt approximates its carrying value. On May 30, 2019, we entered into a credit agreement that amended and restated our existing RCA. See Note 21, Subsequent Events, for further details.

Note 13 – Debt and Available Credit Facilities

As of April 30, 2019 and 2018, our debt of $478.8 million and $360.0 million, respectively, consisted of amounts due under our revolving credit facilities.

We have a revolving credit agreement (“RCA”) with a syndicated bank group led by Bank of America. The RCA consists of a $1.1 billion five-year senior revolving credit facility payable March 1, 2021. Under the RCA, which can be drawn in multiple currencies, we have the option of borrowing at the following floating interest rates: (i) at a rate based on the London Interbank Offered Rate (“LIBOR”) plus an applicable margin ranging from 0.98% to 1.50%, depending on our consolidated leverage ratio, as defined, or (ii) for U.S. dollar-denominated loans only, at the lender’s base rate plus an applicable margin ranging from zero to 0.45%, depending on our consolidated leverage ratio. The lender’s base rate is defined as the highest of (i) the U.S. federal funds effective rate plus a 0.50% margin, (ii) the Eurocurrency rate, as defined, plus a 1.00% margin, or (iii) the Bank of America prime lending rate. In addition, we pay a facility fee ranging from 0.15% to 0.25% depending on our consolidated leverage ratio. We also have the option to request an additional credit limit increase of up to $350 million in minimum increments of $50 million, subject to the approval of the lenders. The RCA contains certain restrictive covenants related to our consolidated leverage ratio and interest coverage ratio, which we were in compliance with as of April 30, 2019 and 2018. Due to the fact that there are no principal payments due until the end of the agreement in the year ended April 30, 2021, we have classified our entire debt obligation as long-term as of April 30, 2019 and 2018.

We have other lines of credit aggregating $2.7 million at various interest rates. There were no outstanding borrowings under these credit lines at April 30, 2019 and 2018.

Our total available lines of credit as of April 30, 2019, were approximately $1.1 billion, of which approximately $0.6 billion was unused. The weighted average interest rates on total debt outstanding during the years ended April 30, 2019 and 2018 were 2.69% and 2.44%, respectively. As of April 30, 2019 and 2018, the weighted average interest rates for total debt were 2.88% and 2.58%, respectively. Based on estimates of interest rates currently available to us for loans with similar terms and maturities, the fair value of our debt approximates its carrying value.

On May 30, 2019, we entered into a credit agreement that amended and restated our existing RCA. See Note 21, Subsequent Events, for further details.
