9. Income Taxes

The following table summarizes the Company’s income tax expense (benefit) and effective income tax rate for the three and nine months ended June 30, 2023 and 2022.

	Three Months Ended June 30,						Nine Months Ended June 30,
	2023			2022			2023			2022
Income (loss) before income taxes	$	24.4		$	15.3		$	(29.6	)	$	(1.6	)
Income tax expense (benefit)		7.6			4.5			(5.5	)		(0.3	)
Effective income tax rate		31.1	%		29.4	%		18.6	%		18.7	%

The increase in the effective tax rate for the three months ended June 30, 2023 when compared to the three months ended June 30, 2022, is primarily attributable to the increase in pre-tax book income period over period.

The decrease in the effective tax rate for the nine months ended June 30, 2023 when compared to the nine months ended June 30, 2022, is primarily attributable to the geographical distribution of pre-tax earnings across legal entities, offset by the expense related to the vesting of restricted stock units that was recorded discretely in the current period.
