Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies We are subject to certain claims and lawsuits typically filed against the consulting and engineering profession, alleging primarily professional errors or omissions. We carry professional liability insurance, subject to certain deductibles and policy limits, against such claims. However, in some actions, parties are seeking damages that exceed our insurance coverage or for which we are not insured. While management does not believe that the resolution of these claims will have a material adverse effect, individually or in aggregate, on our financial position, results of operations or cash flows, management acknowledges the uncertainty surrounding the ultimate resolution of these matters. On July 15, 2019, following an initial January 14, 2019 filing, the Civil Division of the United States Attorney's Office of the United States Department of Justice ("the USAO") filed an amended complaint in the intervention of three qui tam actions filed against our wholly-owned subsidiary, Tetra Tech EC, Inc. ("TtEC"), in the U.S. District Court for the Northern District of California ("the Court"). The complaint alleges False Claims Act ("FCA") violations and breach of contract related to TtEC's contracts to perform environmental remediation services at the former Hunters Point Naval Shipyard in San Francisco, California (the "Covered Conduct"). On March 5, 2024, the Court granted the USAO's motion to amend the filing to include additional claims against TtEC under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") and common law. To explore whether a negotiated resolution was possible, TtEC began engaging in discussions with the USAO during the first quarter of fiscal 2025 regarding a potential resolution of all claims. On January 17, 2025, TtEC entered into a settlement agreement with the United States of America, acting through the USAO and on behalf of the Department of the Navy (collectively, the "United States") an d also fil ed a proposed consent decree with the Court, to resolve this litigation. Under the terms of the settlement agreement and consent decree, TtEC agreed to pay the United States $57 million and $40 million for FCA and CERCLA claims, respectively (the "Settlement Amounts"). In the second quarter of fiscal 2025, we paid the $57 million settlement related to the FCA claim. The $40 million CERCLA settlement was paid at the beginning of the fourth quarter of fiscal 2025. U pon entry of the consent decree by the Court and the United States' receipt of the Settlement Amounts, the United States released TtEC from any, and all civil or administrative monetary claims for the Covered Conduct under the civil FCA, the CERCLA, and other specified civil statutes and common law theories of liability. TtEC entered into the settlement agreement and consent decree to avoid delay, uncertainty and expense of protracted litigation. The settlement agreement and consent decree contain no admission of liability by TtEC. TtEC has initiated litigation with the insurance carrier with which TtEC maintained liability policies regarding the reasonably possible payment or reimbursement of a significant portion of the Settlement Amounts. TtEC can give no assurances as to what portion, if any, of the Settlement Amounts will be recovered from the insurance carrier. Several ancillary claims brought by third-party private plaintiffs arising from the same services provided by TtEC at Hunters Point are also ongoing. The settlement agreement and consent decree do not resolve these ancillary claims. As a result of the settlement agreement and consent decree with the United States and in connection with discussions regarding the ancillary claims, we recorded a $115.0 million charge to operating income ($97.0 million for the settlement and $18.0 million estimated for the ancillary claims, respectively) in the first quarter of fiscal 2025.
