Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is subject to federal, state and local environmental laws and regulations which require that it investigate and remediate the effects of the release or disposal of materials at sites associated with past and present operations, including sites at which the Company has been identified as a potentially responsible party under the federal Superfund laws and comparable state laws. In accordance with the Company’s accounting policy disclosed in Note 2, environmental liabilities are recorded when the Company’s liability is probable and the costs are reasonably estimable. In many cases, however, investigations are not yet at a stage where the Company has been able to determine whether it is liable or, if liability is probable, to reasonably estimate the loss or range of loss, or certain components thereof. Estimates of the Company’s liability are further subject to uncertainties regarding the nature and extent of site contamination, the range of remediation alternatives available, evolving remediation standards, imprecise engineering evaluations and estimates of appropriate cleanup technology, methodology and cost, the extent of corrective actions that may be required, and the number and financial condition of other potentially responsible parties, as well as the extent of their responsibility for the remediation. Accordingly, as investigation and remediation of these sites proceeds, it is likely that adjustments in the Company’s accruals will be necessary to reflect new information. The amounts of any such adjustments could have a material adverse effect on the Company’s results of operations in a given period, but the amounts, and the possible range of loss in excess of the amounts accrued, are not reasonably estimable. Based on currently available information, however, management does not believe that future environmental costs in excess of those accrued with respect to sites with which the Company has been identified are likely to have a material adverse effect on the Company’s financial condition or liquidity. At January 2, 2022, the Company’s reserves for environmental remediation obligations totaled $6.3 million, of which $1.7 million is included in current accrued liabilities with the remainder included in long-term accrued liabilities. The Company periodically evaluates whether it may be able to recover a portion of future costs for environmental liabilities from its insurance carriers and from third parties. The timing of expenditures depends on a number of factors that vary by site, including the nature and extent of contamination, the number of potentially responsible parties, the timing of regulatory approvals, the complexity of the investigation and remediation, and the standards for remediation. The Company expects that it will expend present accruals over many years, and will complete remediation of all sites with which it has been identified in up to thirty years. On April 24, 2018, FLIR entered into a Consent Agreement with the United States Department of State’s Directorate of Defense Trade Controls to resolve allegations regarding the unauthorized export of technical data and defense services to dual and third country nationals in certain of FLIR’s facilities, the failure to properly use and manage export licenses and export authorizations, and failures to report certain payments under 22 CFR Part 130 in potential violation of International Traffic in Arms Regulations (“ITAR”). The Consent Agreement has a four-year term and provides for: (i) a civil penalty of $30.0 million with $15.0 million of this amount suspended on the condition that the funds have or will be used for Department-approved Consent Agreement remedial compliance measures, (ii) the appointment of an external Special Compliance Official to oversee compliance with the Consent Agreement and the ITAR; (iii) two external audits of our ITAR compliance program; and (iv) continued implementation of ongoing remedial compliance measures and additional remedial compliance measures related to automated systems and ITAR compliance policies, procedures, and training. While FLIR has enhanced its trade compliance program more broadly, implemented and continues to implement remedial measures and has undergone its first external audit and just concluded its second external audit of FLIR’s ITAR compliance program, additional adverse disclosures and findings could materially cause incurrence of additional expenses in connection with implementation of remedial measures and result in a substantial adjustment to our revenue and net income. As of January 2, 2022, under the Consent Agreement, $3.5 million remains to be paid by April 24, 2022. FLIR’s investments to date in remedial compliance measures have been more than sufficient to cover the $15.0 million suspension amount. In June 2017, the Bureau of Industry and Security (“BIS”) of the United States Department of Commerce informed FLIR of additional export licensing requirements that restricted the FLIR’s ability to sell certain thermal products without a license to customers in China not identified on a list maintained by the United States Department of Commerce. This action was precipitated by concerns of sale without a license or potential diversion of some of FLIR’s products to prohibited end users and to countries subject to economic and other sanctions implemented by the United States. BIS subsequently favorably modified these restrictions to reduce the applicability of the restrictions to sales of FLIR's Tau camera cores (as opposed to finished products containing Tau camera cores) to customers in China not identified on a list maintained by the United States Department of Commerce and persons in a country other than those in the Export Administration Regulations (“EAR”) Country Group A:5 (Supplement No. 1 to Part 740 of the EAR). FLIR has identified certain shipments that potentially violate these license requirements and voluntary disclosed this matter to BIS. In April 2021, FLIR resolved allegations of misrepresentations made to BIS, between November 2012 and December 2013, in a commodity jurisdiction request relating to newly developed Lepton uncooled focal plane arrays by an administrative settlement and fine of $0.3 million and agreeing to perform two internal audits of its EAR export compliance programs. The first internal audit has been completed and another voluntary disclosure has been filed to report potential violations. FLIR has made other voluntary disclosures to the U.S. Department of State and U.S. Department of Commerce, including to BIS with respect to the shipments of products from non-U.S. jurisdictions which were not licensed due to incorrect de minimis calculation methodology. If FLIR is found to have violated applicable rules and regulations with respect to customers and limitations on the export and end use of its products, FLIR could be subject to substantial fines and penalties, suspension of existing licenses or other authorizations and/or loss or suspension of export privileges. At this time, based on available information, we are unable to reasonably estimate the time it may take to resolve these matters or the amount or range of potential loss, penalty or other government action, if any, that may be incurred in connection with these matters. However, an unfavorable outcome could result in substantial fines and penalties or loss or suspension of export privileges or of particular authorizations that could be material to the Company’s financial position, results of operations or cash flows in and following the period in which such an outcome becomes estimable or known. Certain provisional adjustments have been made for the FLIR historical export compliance matters in Teledyne’s current preliminary estimates of its purchase price allocation. The final acquisition accounting adjustments for these matters may be materially different, as Teledyne obtains additional information on these matters and as additional information is made known during the post-acquisition measurement period. See Note 3 to these Notes to Consolidated Financial Statements for information regarding FLIR historical tax matters that existed at the date of the acquisition, including the Swedish Tax Authority's reassessment of tax for the year ending December 31, 2012 related to one of FLIR’s non-operating subsidiaries in Sweden. Various claims (whether based on U.S. Government or Company audits and investigations or otherwise) may be asserted against the Company related to its U.S. Government contract work, including claims based on business practices and cost classifications and actions under the False Claims Act. Although such claims are generally resolved by detailed fact-finding and negotiation, on those occasions when they are not so resolved, civil or criminal legal or administrative proceedings may ensue. Depending on the circumstances and the outcome, such proceedings could result in fines, penalties, compensatory and treble damages or the cancellation or suspension of payments under one or more U.S. Government contracts. Under government regulations, a company, or one or more of its operating divisions or units, can also be suspended or debarred from government contracts based on the results of investigations. However, although the outcome of these matters cannot be predicted with certainty, management does not believe there is any audit, review or investigation currently pending against the Company of which management is aware that is likely to result in suspension or debarment of the Company, or that is otherwise likely to have a material adverse effect on the Company’s financial condition or liquidity, although the resolution in any reporting period of one or more of these matters could have a material adverse effect on the Company’s results of operations for that period. A number of other lawsuits, claims and proceedings have been or may be asserted against the Company, including those pertaining to product liability, acquisitions, patent infringement, commercial contracts, employment and employee benefits. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to the Company, management does not believe that the disposition of any such pending matters is likely to have a material adverse effect on the Company’s financial condition.
