Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. COMMITMENTS AND CONTINGENCIES The Company is involved in environmental remediation and monitoring activities at its Randolph, Wisconsin manufacturing facility and accrues for related costs, when such costs are determined to be probable and estimable. The Company currently utilizes a pump and treat remediation strategy, which includes semi-annual monitoring and reporting, consulting, and maintenance of monitoring wells. These annual remediation costs are expensed and have ranged from $38 to $131 per year over the past five years. The Company’s estimated remaining liability for these costs is $916 as of both February 28, 2025 and May 31, 2024, measured on an undiscounted basis over an estimated period of 15 years. In fiscal 2019, the Company performed an updated Corrective Measures Study on the site, per a request from the Wisconsin Department of Natural Resources ("WDNR"), and is currently working with the WDNR regarding potential alternative remediation strategies going forward. The Company believes that the current pump and treat strategy is appropriate for the site. In fiscal 2022, in collaboration with the WDNR, the Company initiated an in-situ chemical remediation pilot study, which ran over a two-year period. The results of this study were submitted to the WDNR as part of our standard annual report. If the WDNR were to require a change from the current pump and treat remediation strategy, this change could result in an increase in future costs and, ultimately, an increase in the currently recorded liability, with an offsetting charge to operations in the period recorded. The Company has recorded $100 as a current liability as of February 28, 2025, and the remaining $816 is recorded in other non-current liabilities in the condensed consolidated balance sheets. In the third quarter of fiscal year 2025, the Company recorded a gain related to a settlement regarding the Company's prior acquisition of certain fixed assets. The amount of $2,700 was received in the third quarter of fiscal year 2025. This amount was partially offset by a related fixed asset impairment of $2,055, which was due to the asset no longer being in use. The amount was recorded within General and administrative on the condensed consolidated statements of operations within the Company's Food Safety operating segment. Related to the Company's other contingent liabilities, a loss of $1,400 was recorded in the third quarter of fiscal year 2025. This contingency loss was driven by an updated valuation of the performance milestone liability for the Company's CAPInnoVet, Inc. transaction. Finally, in the third quarter of fiscal year 2025, the Company reversed a liability of $930 related to a contingent liability that was recorded as part of the Corvium, Inc. transaction. The final milestone payment was not achieved, resulting in a full reversal of the liability. In the third quarter of fiscal year 2024, the Company received $1,265 of business interruption insurance proceeds relating to fire damage that occurred in the fourth quarter of fiscal year 2023 at one of our Animal Safety lab facilities. The proceeds were recorded within Cost of Revenues in the condensed consolidated statements of operations. The Company is subject to certain legal and other proceedings in the normal course of business that, in the opinion of management, are not expected to have a material effect on its future results of operations or financial position.
