Debt and Available Credit Facilities [Abstract]
Debt and Available Credit Facilities	Note 12 - Debt and Available Credit Facilities As of April 30, 2017 and 2016, the Company’s debt of approximately $365.0 million and $605.0 million, respectively consisted of amounts due under its revolving credit facilities. On March 1, 2016, the Company amended and extended its existing revolving credit agreement (“RCA”) with a syndicated bank group led by Bank of America. The previous RCA consisted of a $940 million senior revolving credit facility due on November 2, 2016. The new agreement consists of a $1.1 billion five-year senior revolving credit facility payable March 1, 2021. The proceeds of the amended facility will be used for general corporate purposes including seasonal operating cash requirements investments in technology systems and new businesses, and strategic acquisitions. Under the agreement, which can be drawn in multiple currencies, the Company has 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 the Company’s 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 the Company’s 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, the Company pays a facility fee ranging from 0.15% to 0.25% depending on the Company’s consolidated leverage ratio. The Company also has 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 credit agreement contains certain restrictive covenants related to the Company’s consolidated leverage ratio and interest coverage ratio, which the Company was in compliance with as of April 30, 2017. Due to the fact that there are no principal payments due until the end of the agreement in fiscal year 2021, the Company has classified its entire debt obligation as long-term as of April 30, 2017 and 2016. As part of the amendment, the Company paid $3.4 million in debt financing costs in fiscal year 2016 which were capitalized and included in the Other Assets line item in the Consolidated Statements of Financial Position. On October 31, 2015, the Company renewed its U.S. dollar facility with TD Bank, N.A. which was equally ranked with the Company’s previous agreement with Bank of America - Merrill Lynch and The Royal Bank of Scotland plc, and Santander Bank. The agreement consisted of a $50 million 364-day revolving credit facility which was drawn in fiscal year 2015. The facility was terminated and fully paid off with the proceeds of the RCA refinancing on March 1, 2016. On August 6, 2015, the Company amended its December 22, 2014 364-day U.S. dollar revolving credit facility reinstated every 30 days with Santander Bank, N.A. by increasing the facility to $100 million from $50 million. The additional $50 million was drawn during August and was used to repay a portion of the senior revolving credit facility. The facility was equally ranked with the Company’s previous agreement with Bank of America - Merrill Lynch and The Royal Bank of Scotland plc, and TD Bank, N.A. The facility was fully paid on April 29, 2016. This facility’s termination date was May 23, 2016 and was not renewed. The Company and its subsidiaries have other lines of credit aggregating $6.8 million at various interest rates. There were no outstanding borrowings under these credit lines at April 30, 2017 and 2016. The Company’s total available lines of credit as of April 30, 2017 were approximately $1.1 billion, of which approximately $0.7 billion was unused. The weighted average interest rates on total debt outstanding during fiscal years 2017 and 2016 were 2.19% and 1.88%, respectively. As of April 30, 2017 and 2016, the weighted average interest rates for the total debt were 2.74% and 2.12%, respectively. Based on estimates of interest rates currently available to the Company for loans with similar terms and maturities, the fair value of the Company’s debt approximates its carrying value.
