(3)Represents certain environmental liabilities intended to be discharged upon effectiveness of the plan of reorganization.

(4)In accordance with the agreement in principle reached with the Opioid Claimants on September 2, 2021, and subsequently memorialized in the Amended Plan on September 29, 2021, the Company recorded an accrual of $125.0 million related to the additional payment expected to be made on the eighth anniversary of the effective date of emergence, which has been classified as LSTC in the Company's consolidated balance sheet as of December 31, 2021.

(5)The decrease in other current and non-current liabilities was attributable to (1) the Bankruptcy Court's approval of the Company's rejection of its Bedminster facility lease, which resulted in a $34.8 million adjustment to the carrying value of the respective lease liability in LSTC to reflect the estimated allowed claim amount and (2) a decrease of $15.6 million in the fair value of contingent consideration related to MNK-6105 and MNK-6106 . These decreases were partially offset by an increase of $17.3 million related to Acthar Gel royalty accruals as a result of the December 2021 Bankruptcy Court ruling, which found that the Acthar Insurance Claimants' (as defined in Note 19) administrative claims were without merit. The remaining change in other current and non-current liabilities was attributable to various increases and decreases as a result of adjustments in the ordinary course of business.
