[3] The decrease in the total net deferred tax liability from December 31, 2019 to December 31, 2020 is primarily attributable to a decrease in deferred tax liabilities related to intangibles, partially offset by an increase in valuation allowances representing the amounts determined to be unrecoverable, and 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, inventory, net operation loss/credit carry forwards, partially offset by a decrease in employee benefits.
