[3] The decrease in the total net deferred tax liability from December 31, 2018 to December 31, 2019 is primarily attributable to a decrease in deferred tax liabilities related to intangibles and valuation allowances representing the amounts determined to be unrecoverable, partially offset by an increase in deferred tax liabilities related to property, plant and equipment. In addition, the decrease in the total net deferred tax liability was also attributable to an increase in deferred tax assets related to prepaid/deferred items, employee benefits, partially offset by a decrease in net operating loss/credit carryforwards.
