Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The effective income tax rate for the three months ended July 31, 2020 was 35.4% versus 22.3% in the prior year. The effective income tax rate for the six months ended July 31, 2020 was 19.0% versus 20.0% in the prior year. The increase in the effective income tax rate for the three months ended July 31, 2020 was primarily due to the application of an updated estimated annual effective income tax rate, which is influenced by the jurisdictional mix of earnings taxed at the statutory tax rates applicable to each jurisdiction and an estimated increase in the Global Intangible Low-Taxed Income ("GILTI") tax, each of which reflect the impact of COVID-19 on the Company's results of operations. The effective income tax rate for the six months ended July 31, 2020 reflected the impact of certain discrete items recognized in the period. The Company's effective income tax rate could be negatively impacted to the extent earnings are lower than anticipated in countries that have lower statutory tax rates and higher than anticipated in countries that have higher statutory tax rates. The effective income tax rate for the six months ended July 31, 2019 included the recognition of an income tax benefit of $7.5 million, or 230 basis points, related to an increase in the estimated 2018 Foreign Derived Intangible Income ("FDII") benefit as a result of U.S. Treasury guidance issued during the three months ended April 30, 2019. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") was enacted. The Company has analyzed the provisions of the CARES Act, which provide for the full expensing of qualified leasehold improvements, modifications to charitable contribution and net operating loss limitations, modifications to the deductibility of business interest expense, as well as Alternative Minimum Tax ("AMT") credit acceleration. The enactment of this legislation did not have a significant impact on the effective income tax rate in the six months ended July 31, 2020. During the three and six months ended July 31, 2020, the change in the gross amount of unrecognized tax benefits and accrued interest and penalties was not significant. The Company conducts business globally and, as a result, is subject to taxation in the U.S. and various state and foreign jurisdictions. As a matter of course, tax authorities regularly audit the Company. The Company's tax filings are currently being examined by a number of tax authorities, both in the U.S. and in foreign jurisdictions. Ongoing audits where subsidiaries have a material presence include New York City (tax years 2011–2015) and New York State (tax years 2012–2018). Tax years from 2013–present are open to examination in the U.S. Federal jurisdiction and 2006–present are open in various state, local and foreign jurisdictions. As part of these audits, the Company engages in discussions with taxing authorities regarding tax positions. As of July 31, 2020, unrecognized tax benefits are not expected to change materially in the next 12 months. Future developments may result in a change in this assessment.
