Income Tax Disclosure [Abstract]
Provision for Income Taxes	Provision for Income Taxes The overall effective income tax rate for the three months ended January 31, 2021 was 20.0%, and the effective income tax rate for the six months ended January 31, 2021 was 20.4%. These rates were both favorably impacted by certain foreign rate differences which include certain interest income not subject to corporate income tax and also by certain foreign return-to-provision adjustments. The overall effective income tax rate for the three months ended January 31, 2020 was 22.5%, and the effective income tax rate for the six months ended January 31, 2020 was 23.8%. These rates were both favorably impacted by certain foreign rate differences which include certain interest income not subject to corporate income tax. This benefit for the six months ended January 31, 2020 was partially offset by additional tax expense from the vesting of share-based compensation awards. Within the next 12 months, the Company anticipates a decrease of approximately $7,900 in unrecognized tax benefits, and $2,000 in accrued interest related to unrecognized tax benefits recorded as of January 31, 2021, from expected settlements or payments of uncertain tax positions and lapses of the applicable statutes of limitations. Actual results may differ from these estimates. The Company files income tax returns in the U.S. federal jurisdiction and in many U.S. state and foreign jurisdictions. For U.S. federal income tax purposes, fiscal years 2017 through 2019 remain open and could be subject to examination. In major state and major foreign jurisdictions, fiscal years 2017 through 2019 generally remain open and could be subject to examination. The Company is currently under exam by certain U.S. state tax authorities for the fiscal years ended July 31, 2015 through 2017. The Company believes it has adequately reserved for its exposure to additional payments for uncertain tax positions in its liability for unrecognized tax benefits.
