During the nine months ended January 31, 2019, the Company finalized the accounting policy decision with respect to the new Global Intangible Low-Taxed Income ("GILTI") tax rules and has concluded that GILTI will be treated as a periodic charge in the year in which it arises. Therefore, the Company will not record deferred taxes for the basis associated with GILTI earnings. The Company has included estimated tax expense related to GILTI for current year operations in the forecasted effective tax rate.
