INCOME TAXES

Income tax provisions for interim quarterly periods are based on an estimated annual effective income tax rate calculated separately from the effect of significant, infrequent or unusual discrete items related specifically to interim periods. The following summarizes income tax expense and the effective tax rate in each interim period:

	Three months ended December 31
(In millions)	2024			2023
Income tax expense	$	33.3		$	11.9
Effective tax rate percentage	26.2		%	26.0		%

The respective increases in income tax expense and effective tax rate for the three months ended December 31, 2024 is primarily driven by an increase in pre-tax income and unfavorable discrete items compared to favorable discrete items in the prior year.
