(4)The Company decreased a valuation allowance of $2.1 million during 2021.
(5)The Company recorded a valuation allowance of $13.1 million during 2020. The net addition is primarily attributable to the increase in the DTA for the portion of the 2020 net operating loss that is carried forward to future years and the Zyla Merger. The deduction is related to the DTL recorded in the opening balance sheet for Zyla and the carryback of the 2020 net operating loss carryback to the 2018 and 2019 years.
