Income Taxes	9 Months Ended
Income Taxes	Oct. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The effective income tax rate for the three months ended October 31, 2020 was 19.9% versus 25.4% in the prior year. The effective income tax rate for the nine months ended October 31, 2020 was 20.3% versus 21.3% in the prior year. The effective income tax rate for the three months and nine months ended October 31, 2020 was impacted by the reversal of previously established reserves for uncertain tax positions resulting from the favorable conclusion of a tax examination and the expiration of certain statutes of limitations, the impact of non-deductible transaction-related expenses, as well as 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. 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 three and nine months ended October 31, 2019 was increased by an income tax expense of $5.8 million, or 550 basis points and 130 basis points, respectively, due to a reduction in the estimated Foreign Derived Intangible Income ("FDII") benefit for fiscal 2019. The effective income tax rate for the nine months ended October 31, 2019 included the recognition of an income tax benefit of $7.5 million, or 170 basis points, related to an increase in the estimated fiscal 2018 FDII benefit as a result of U.S. Treasury guidance issued during the three months ended April 30, 2019. In March 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 nine months ended October 31, 2020. During the three and nine months ended October 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 2017–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 October 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.
