Income Taxes

3 Months Ended

Aug. 31, 2019

The Company recognizes interest and penalties related to uncertain tax benefits through income tax expense in its Condensed Consolidated Statement of Comprehensive Income. Interest and penalties recognized in the Company's Condensed Consolidated Statement of Comprehensive Income were negligible for the three months ended August 31, 2019 and September 1, 2018.

The Company's recorded liability for potential interest and penalties related to uncertain tax benefits was:



(In millions)	August 31, 2019		June 1, 2019
Liability for interest and penalties	$	0.8	$	0.7
Liability for uncertain tax positions, current	$	2.0	$	1.9

In determining the provision for income taxes for the three months ended August 31, 2019, the Company used an estimated annual effective tax rate which was based on expected annual income and statutory tax rates across the various jurisdictions in which it operates. The effective tax rates were 21.0% and 20.0%, respectively, for the three month periods ended August 31, 2019 and September 1, 2018. The year over year increase in the effective tax rate for the three months ended August 31, 2019 resulted from a decrease in the current quarter tax deduction for certain stock based compensation awards as compared to the same quarter in the prior year. The effective tax rate for the three months ended August 31, 2019 is the same as the United States federal statutory rate. The effective tax rate for the three months ended September 1, 2018 is lower than the United States federal statutory rate due to a tax deduction for the vesting of certain stock-based compensation awards.

The Company is subject to periodic audits by domestic and foreign tax authorities. Currently, the Company is undergoing routine periodic audits in both domestic and foreign tax jurisdictions. It is reasonably possible that the amounts of unrecognized tax benefits could change in the next twelve months because of the audits. Tax payments related to these audits, if any, are not expected to be material to the Company's Condensed Consolidated Statements of Comprehensive Income.

For the majority of tax jurisdictions, the Company is no longer subject to state, local, or non-United States income tax examinations by tax authorities for fiscal years before 2016.
