Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Insurance The Company maintains certain insurance policies that maintain large deductibles up to approximately $2 million, some with or without stop-loss limits, depending on market availability. Insurance policies at certain locations are based on a percentage of the insured assets, for which deductibles for certain property may exceed $15.0 million in the event of a catastrophic event. In addition, the Company purchased representation and warranty insurance in support of some acquisitions, in which deductibles could reach $4.0 million. Litigation On February 16, 2023, the Company was informed by the U.S. Department of Justice (DOJ) that in conjunction with the U.S. Fish and Wildlife Service (USFWS), it had commenced an investigation into the Company’s conduct regarding several shipments of non-human primates from Cambodia. On February 17, 2023 the Company received a grand jury subpoena requesting certain documents related to such investigation. The Company is aware of a parallel civil investigation being undertaken by the DOJ and USFWS. The Company is cooperating with the DOJ and the USFWS and believes that the concerns raised with respect to the Company’s conduct are without merit. The Company maintains a global supplier onboarding and oversight program incorporating risk-based due diligence, auditing, and monitoring practices to help ensure the quality of our supplier relationships and compliance with applicable U.S. and international laws and regulations, and has operated under the belief that all shipments of non-human primates it received satisfied the material requirements, documentation and related processes and procedures of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) documentation and related processes and procedures, which guides the release of each import by USFWS. Notwithstanding our efforts and good-faith belief, in connection with the civil investigation, the Company has voluntarily suspended future shipments of non-human primates from Cambodia until such time that the Company and USFWS can agree upon and implement additional procedures to reasonably ensure that non-human primates imported to the United States from Cambodia are purpose-bred. While these discussions with USFWS are ongoing, the Company has also agreed to continue to care for the Cambodia-sourced non-human primates from certain recent shipments that are now in the United States. The carrying value of the inventory related to these shipments is approximately $20 million. We are not able to predict what action, if any, might be taken in the future by the DOJ, USFWS or other governmental authorities as a result of the investigations. Neither the DOJ nor USFWS has provided the Company with any specific timeline or indication as to when these investigations or discussions regarding future processes and procedures will be concluded or resolved. Because it is in the early stages, the Company cannot predict the timing, outcome or possible impact of the investigations, including without limitation any potential fines, penalties or liabilities. Aside from the matter above, the Company believes there are no other matters pending against the Company that could have a material impact on the Company’s business, financial condition, or results of operations. Guarantees The Company enters into certain agreements with other parties in the ordinary course of business that contain indemnification provisions. These typically include agreements with directors and officers, business partners, contractors, landlords, and customers. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities. These indemnification provisions generally survive termination of the underlying agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is unlimited. However, to date the Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, the estimated fair value of these obligations is minimal. Purchase Obligations The Company enters into unconditional purchase obligations, in the ordinary course of business, that include agreements to purchase goods or services that are enforceable and legally binding and that specify all significant terms including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. These unconditional purchase obligations exclude agreements that are cancellable at any time without penalty. The aggregate amount of the Company’s unconditional purchase obligations totaled approximately $375 million as of December 31, 2022 and the majority of these obligations are expected to be settled during 2023.
