Summary of Tax Credit Carryforwards [Table Text Block]

The benefit relating to capital loss, net operating loss (NOL) and credit carryforwards included in the above table at December 31, 2019 consists of:

Dollar amounts in millions	Net Operating Loss		Benefit Amount		Valuation Allowance			Expiration Beginning in
Federal NOL carryforwards	$	11	$	2	$	—		No expiration
State NOL carryforwards	266		10		—			2021

			$	28	$	(5	)

We periodically review the need for valuation allowances against deferred tax assets and recognize these deferred tax assets to the extent that their realization is more likely than not. As part of our review, we consider all positive and negative evidence, including earnings history, the future reversal of deferred tax liabilities, and the relevant expirations of carryforwards. We believe that the valuation allowances provided are appropriate. If future years’ earnings differ from the estimates used to establish these valuation allowances, or other objective positive or negative evidence arises, we may be required to record an adjustment resulting in an impact on tax provision

(benefit) for that period.
