12.    Income Taxes

For the three-month and six-month periods ended June 30, 2022 and 2021, our income tax expense and effective income tax rates were as follows (dollars in millions):

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2022			2021			2022			2021
Income tax expense	$	38		$	15		$	59		$	30
Effective income tax rate		28	%		28	%		27	%		28	%

We estimate our differences between taxable income or loss and recorded income or loss on an annual basis. Our tax provision for each quarter is based upon these full year projections, which are revised each reporting period. These projections incorporate estimates of permanent differences between U.S. GAAP income or loss and taxable income or loss, state income taxes and adjustments to our liability for unrecognized tax benefits to adjust our statutory Federal income tax rate of 21% to our effective income tax rate. For the six-months ended June 30, 2022, these estimates increased or decreased our statutory Federal income tax rate to our effective income tax rate of 27% as follows: state income taxes added 5% and permanent differences between our U.S. GAAP income and taxable income resulted in an increase of 1%. For the six-months ended June 30, 2021, these estimates increased or decreased our statutory Federal income tax rate to our effective income tax rate of 28% as follows: state income taxes added 5% and permanent differences between our U.S. GAAP income and taxable income resulted in an increase of 2%.

During the six-months ended June 30, 2022, we made $119 million of federal and state income tax payments, net of refunds. During the remainder of 2022, we anticipate making income tax payments (net of our expected $21 million refund) of approximately $70 million to $90 million. As of June 30, 2022, we have an aggregate of approximately $337 million of various state operating loss carryforwards, of which we expect that approximately half will be utilized.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, contains modifications on the limitation of business interest for tax years beginning in 2019 and 2020, and permits net operating loss (“NOL”) carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. During 2020, we carried back certain net operating losses resulting in a refund of $21 million, that is currently outstanding.
