Income Taxes

3 Months Ended

Mar. 31, 2021

At March 31, 2021, the Company had gross uncertain tax benefits of $110.1 million, of which $68.4 million, if recognized, would impact the effective tax rate.

The following is a reconciliation of the liability for uncertain tax positions (in millions):


Balance at December 31, 2020	$	100.7
Additions for tax positions	9.5
Reductions for tax positions	(0.1)
Balance at March 31, 2021	$	110.1

The Company recognizes interest and penalties accrued related to uncertain tax positions in income tax expense. The amounts recognized in income tax expense for interest and penalties during the three months ended March 31, 2021 and 2020 were not significant.

The effective tax rate for the three months ended March 31, 2021 was 19.5%, compared with 20.1% for the three months ended March 31, 2020. The higher rate for 2020 reflects the gain on the sale of the Reading Alloys business, resulting in an additional $31.4 million of income tax expense, at an effective rate of 22.3%.
