Income Taxes [Abstract]
Income Taxes	Note 13 — Income Taxes The effective tax rate for the three months ended July 31, 2020 was 45.1% compared to 8.6% for the three months ended July 31, 2019. The rate for the three months ended July 31, 2020 was greater than the rate for the corresponding prior period due to an increase in the UK statutory rate discussed below and a $0.5 million discrete item relating to compensation deductions from restricted stock which vested at lower values than the values at time of grant. During the first quarter of fiscal 2021, the U.K. officially enacted legislation that increased its statutory rate from 17% to 19%. This resulted in a $6.7 million non-cash deferred tax expense from the re-measurement of our applicable U.K. net deferred tax liabilities.
