Income Taxes	3 Months Ended
	Jul. 31, 2019
Income Taxes [Abstract]
Income Taxes	Note 13 — Income Taxes The effective tax rate for the three months ended July 31, 2019 was 8.6%, compared to 22.8% for the three months ended July 31, 2018. The rate for the three months ended July 31, 2019 was less than the rate for the corresponding prior period due to certain net discrete items totaling $0.4 million, which had a disproportionately large impact on our rate because of our relatively small amount of pretax income. Excluding the effects of these discrete items, the rate for the three months ended July 31, 2019 would have been 22.5%.
