General	General Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Teledyne Technologies Incorporated (“Teledyne” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in notes to consolidated financial statements have been condensed or omitted pursuant to such rules and regulations, but resultant disclosures are in accordance with generally accepted accounting principles in the United States (“GAAP”) as they apply to interim reporting. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes in Teledyne’s Annual Report on Form 10-K for the fiscal year ended January 2, 2022 (“2021 Form 10-K”). In the opinion of Teledyne’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, Teledyne’s consolidated financial position as of October 2, 2022 and the consolidated results of operations, consolidated comprehensive income (loss) and consolidated cash flows for the third quarter and nine months ended October 2, 2022. The results of operations and cash flows for the periods ended October 2, 2022 and cash flows for the nine months ended October 2, 2022 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year. Certain prior year amounts have been reclassified to conform to the current period presentation. In the current year, gain (loss) on debt extinguishment is presented as separate line item on the income statement. Teledyne had $118.1 million of cash equivalents at October 2, 2022 and an immaterial amount of cash equivalents at January 2, 2022.

Business Combination and Asset Acquisition [Abstract]
Business Combinations, Goodwill and Acquired Intangible Assets	Business Combinations, Goodwill and Acquired Intangible Assets Acquisition of FLIR Systems, Inc. On May 14, 2021, Teledyne acquired the outstanding stock of FLIR Systems, Inc. ( “FLIR”) for approximately $8.1 billion, comprising of net cash payments of $3.7 billion, net Teledyne share issuances of $3.9 billion, and the assumption of FLIR debt of $0.5 billion. FLIR stockholders received $28.00 per share in cash and 0.0718 shares of Teledyne common stock for each FLIR share, and Teledyne issued approximately 9.5 million shares at $409.41 per share. See Note 3 to the Notes to Consolidated Financial Statements in Teledyne’s 2021 Form 10-K for additional information regarding the FLIR acquisition. Founded in 1978, FLIR is an industrial technology company focused on intelligent sensing solutions for defense and industrial applications. FLIR technologies include thermal imaging systems, visible-light imaging systems, locater systems, measurement and diagnostic systems, and advanced threat-detection solutions. FLIR is part of the Digital Imaging segment. The significant factors that resulted in recognition of goodwill were: (a) the purchase price was based on cash flow and return on capital projections assuming integration with our businesses and (b) the calculation of the fair value of tangible and intangible assets acquired that qualified for recognition. Goodwill resulting from the FLIR acquisition will not be deductible for tax purposes. The following table presents the final purchase price allocation for FLIR, as the measurement period closed in the second quarter of 2022. We accounted for the FLIR acquisition under the acquisition method and measured identifiable assets acquired and liabilities assumed of the acquiree at the fair values on the closing date. The Company has completed the process of specifically identifying the amounts assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the FLIR acquisition. The fair values of acquired intangibles were determined based on estimates and assumptions deemed reasonable by the Company. Fair values allocated to the assets acquired and liabilities assumed - FLIR (in millions): Cash and cash equivalents $ 287.7 Accounts receivables, net 241.3 Unbilled receivables, net 72.1 Inventories, net 519.4 Prepaid expenses and other current assets 54.8 Total current assets 1,175.3 Property, plant and equipment 354.1 Goodwill 5,939.7 Acquired intangible assets 2,490.0 Other long-term assets 141.9 Total assets acquired $ 10,101.0 Accounts payable 144.7 Accrued liabilities 612.1 Total current liabilities assumed 756.8 Long-term debt, net 496.8 Long-term deferred tax liabilities 603.3 Other long-term liabilities 335.5 Total liabilities assumed 2,192.4 Consideration transferred $ 7,908.6 Consideration transferred, net of cash acquired (a) $ 7,620.9 (a) The consideration transferred included approximately $3.9 billion of Teledyne shares issued to existing shareholders of the acquired company. This $3.9 billion of equity consideration is a non-cash transaction. An immaterial portion of the cash consideration for certain vested FLIR restricted stock awards was deferred at the election of the award holder and will be paid out in future periods. During fiscal year 2018, the Swedish Tax Authority (“STA”) issued a reassessment of tax for the year ending December 31, 2012 to one of FLIR’s non-operating subsidiaries in Sweden. The total taxes, penalties and interest levied by the STA totaled SEK 3.1 billion ($364.7 million based on exchange rates as of the acquisition date). The reassessment concerned the use of tax credits applied against capital gains pursuant to European Union Council Directive 2009/133/EC, commonly referred to as the EU Merger Directive, and the reassessment levied significant taxes and penalties. In March 2020, FLIR received an adverse judgment from the First Instance Court of Sweden regarding the STA’s reassessment. FLIR appealed the decision to the Administrative Court of Appeal in Stockholm, Sweden. After completing an extensive analysis, including consultation with outside specialists, Teledyne recorded a liability for this uncertain tax position that reflected the most likely outcome for this tax matter under the acquisition method for business combinations in the third quarter of 2021, which was included within accrued liabilities on the consolidated balance sheet at January 2, 2022. On January 26, 2022, the Administrative Court of Appeal in Stockholm, Sweden generally affirmed the March 2020 ruling of the First Instance Court and determined an estimated tax liability in the amount of SEK 2.765 billion. We paid the tax on February 2, 2022 totaling $296.4 million. We have requested for permission to appeal this ruling to the Swedish Administrative Supreme Court, and we received notification in the fourth quarter of 2022 that this appeal was denied. During the second quarter of 2022, the Company finalized the measurement period including reviewing and identifying acquisition accounting adjustments for a number of acquired tax positions of FLIR that may meet the definition of an acquired uncertain tax position. In addition to the STA matter described above, the Company recorded $187.6 million of purchase accounting adjustments for the accrual of other uncertain tax positions of FLIR. These amounts are included within other long-term liabilities on the Condensed Consolidated Balance Sheet. The following table is a summary at the acquisition date of the acquired intangible assets and weighted average useful life in years for the FLIR acquisition made in 2021 (dollars in millions): Intangibles subject to amortization: Intangible Assets Weighted average useful life in years Proprietary technology $ 1,355.0 9.7 Customer list/relationships 450.0 14.4 Total intangibles subject to amortization 1,805.0 10.9 Intangibles not subject to amortization: Trademarks 685.0 Total acquired intangible assets $ 2,490.0 The unaudited proforma information below assumes that FLIR had been acquired at the beginning of the 2020 fiscal year and includes the effect of transaction accounting adjustments. These adjustments include financing and interest costs associated with debt to fund the acquisition, amortization of acquired intangible assets, depreciation of the fair value step-up of acquired property, plant and equipment, amortization of inventory fair value step-up (assumed to be fully amortized in 2020) and tax related effects as well as the issuance of Teledyne common stock in connection with the acquisition. This unaudited proforma financial information is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have resulted had the acquisition been in effect at the beginning of the 2020 fiscal year. In addition, the unaudited proforma results are not intended to be a projection of future results and do not reflect any operating efficiencies or cost savings that might be achievable. The following table presents proforma net sales, net income and earnings per share data assuming FLIR was acquired at the beginning of the 2020 fiscal year: Third Quarter (a) Nine Months (a) (unaudited - in millions, except per share amounts) 2021 2021 Net sales $ 1,311.9 $ 3,859.9 Net income $ 164.3 $ 356.8 Basic earnings per common share $ 3.53 $ 8.50 Diluted earnings per common share $ 3.44 $ 8.28 (a) The above unaudited proforma information is presented for the FLIR acquisition as it is considered a material acquisition. Acquisition of NL Acoustics During the third quarter of 2022, the Company acquired an approximate 80% majority interest in Noiseless Acoustics Oy ("NL Acoustics"), paying $11.9 million in net cash during the period, with an immaterial amount payable next year. NL Acoustics, located in Helsinki, Finland, designs and manufactures acoustics imaging instruments and predictive maintenance solutions. NL Acoustics is part of the Digital Imaging segment. The minority ownership interest in shares of NL Acoustics held by a third party is classified as a redeemable noncontrolling interest on the condensed consolidated balance sheet due to a put option under which the third party may require the Company to purchase the remaining ownership interest, with the put option exercisable beginning in the third quarter of 2025. The redeemable noncontrolling interest is measured at the greater of the amount that would be paid if settlement occurred as of the balance sheet date based on the contractually defined redemption value and its carrying amount adjusted for net income (loss) attributable to the noncontrolling interest. Adjustments to the carrying value of the redeemable noncontrolling interest are recorded through retained earnings. Changes in the redeemable noncontrolling interest balance during the period were not material. Goodwill and Acquired Intangible Assets Teledyne’s goodwill was $7,718.2 million at October 2, 2022 and $7,986.7 million at January 2, 2022, with the decrease primarily related to the impact of foreign currency translation. Teledyne’s net acquired intangible assets were $2,421.8 million at October 2, 2022 and $2,741.6 million at January 2, 2022. The decrease in the balance of net acquired intangible assets primarily reflected the impact of foreign currency translation as well amortization of acquired intangible assets. Acquired intangible assets are summarized as follows: October 2, 2022 January 2, 2022 Acquired intangible assets (in millions): Gross carrying amount Accumulated amortization Net carrying amount Gross carrying amount Accumulated amortization Net carrying amount Proprietary technology $ 1,610.4 $ 445.8 $ 1,164.6 $ 1,767.7 $ 358.2 $ 1,409.5 Customer list/relationships 577.2 163.3 413.9 616.2 141.8 474.4 Patents 0.6 0.6 — 0.6 0.6 — Non-compete agreements 0.9 0.9 — 0.9 0.9 — Trademarks 5.4 4.2 1.2 4.5 3.9 0.6 Backlog 15.4 15.4 — 16.3 16.3 — Total intangibles subject to amortization 2,209.9 630.2 1,579.7 2,406.2 521.7 1,884.5 Intangibles not subject to amortization: Trademarks 842.1 — 842.1 857.1 — 857.1 Total acquired intangible assets $ 3,052.0 $ 630.2 $ 2,421.8 $ 3,263.3 $ 521.7 $ 2,741.6

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments Teledyne transacts business in various foreign currencies and has international sales and expenses denominated in foreign currencies, subjecting the Company to foreign currency risk. The Company’s primary foreign currency risk management objective is to protect the U.S. dollar value of future cash flows and minimize the volatility of reported earnings. The Company utilizes foreign currency forward contracts to reduce the volatility of cash flows primarily related to forecasted revenues and expenses denominated in Canadian dollars for our Canadian companies, and in British pounds for our UK companies. These contracts are designated and qualify as cash flow hedges. The Company has also converted U.S. dollar denominated, variable rate and fixed rate obligations into euro fixed rate obligations using a receive float, pay fixed cross currency swap, and a receive fixed, pay fixed cross currency swap. These cross currency swaps are designated as cash flow hedges. In addition the Company has converted domestic U.S. variable rate debt to fixed rate debt using a receive variable, pay fixed interest rate swap. The interest rate swap is also designated as a cash flow hedge. During the nine months ended October 2, 2022, the Company liquidated its cross currency swap positions and replaced them with cross currency swaps reflecting current market terms. The liquidations resulted in a cash benefit of $47.8 million, which was primarily recorded in cash flow from financing activities in the condensed consolidated statement of cash flows. The effectiveness of the cash flow hedge forward contracts is assessed prospectively and retrospectively using regression analysis as well as using other timing and probability criteria. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedges, and hedges must be highly effective in offsetting changes to future cash flows on hedged transactions. The effective portion of the cash flow hedge forward contracts’ gains or losses resulting from changes in the fair value of these hedges is initially reported, net of tax, as a component of AOCI in stockholders’ equity until the underlying hedged item is reflected in our condensed consolidated statements of income, at which time the effective amount in AOCI is reclassified to revenue in our condensed consolidated statements of income. Net deferred losses recorded in AOCI, net of tax, for the forward contracts that will mature in the next twelve months total $8.0 million. These losses are expected to be offset by anticipated gains in the value of the forecasted underlying hedged item. Amounts related to the cross currency swaps and interest rate swap expected to be reclassified from AOCI into income in the next twelve months total $1.1 million. In the event that the underlying forecasted transactions do not occur, or it becomes remote that they will occur, within the defined hedge period, the gains or losses on the related cash flow hedges will be reclassified from AOCI to other income or expense. During the current reporting period, all forecasted transactions occurred and, therefore, there were no such gains or losses reclassified to other income and expense. As of October 2, 2022, Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $172.0 million. These foreign currency forward contracts have maturities ranging from December 2022 to February 2024. Teledyne had foreign currency forward contracts designated as cash flow hedges to buy British pounds and to sell U.S. dollars totaling $22.9 million. These foreign currency forward contracts have maturities ranging from December 2022 to February 2024. The cross currency swaps have notional amounts of €130.0 million and $125.0 million, and €156.0 million and $150.0 million, and mature in March 2023 and October 2024, respectively. The interest rate swap has a notional amount of $125.0 million and matures in March 2023. In addition, Teledyne manages the risk of changes in the fair value of certain monetary liabilities attributable to changes in exchange rates. Teledyne manages these risks by using currency forward contracts formally designated and effective as fair value hedges. Hedge effectiveness is generally determined by evaluating the alignment of the hedging instrument's critical terms with the critical terms of the hedged item. The forward points attributable to the hedging instruments are excluded from the assessment of effectiveness and amortized to other income or expense, net using a systematic and rational methodology. Differences between the change in the fair value of the excluded component and amounts recognized under the systematic and rational method are recognized in other comprehensive income (loss). The change in fair value of the hedging instruments attributable to the hedged risk is reported in the other income or expense, net. The change in fair value of the hedged item attributable to the hedged risk is reported as an adjustment to its carrying value and also in other income or expense, net. At October 2, 2022, Teledyne had no forward contracts designated as fair value hedges. The effect of derivative instruments designated as cash flow hedges in the condensed consolidated financial statements for the third quarter and nine months ended October 2, 2022 and October 3, 2021 was as follows (in millions): Third Quarter Nine Months 2022 2021 2022 2021 Net gain (loss) recognized in AOCI - Foreign Exchange Contracts (a) $ 10.2 $ (5.6) $ 36.0 $ 18.3 Net gain (loss) reclassified from AOCI into revenue - Foreign Exchange Contracts (a) $ (1.0) $ 1.8 $ (1.4) $ 7.8 Net gain (loss) recognized in AOCI - Interest Rate Contracts $ 0.3 $ (0.1) 2.3 $ (0.1) Net gain (loss) reclassified from AOCI into other income and expense, net - Foreign Exchange Contracts (b) $ 17.8 $ 6.4 $ 38.9 $ 14.7 Net gain reclassified from AOCI into interest expense - Foreign Exchange Contracts $ 1.6 $ 0.9 $ 3.5 $ 2.6 Net gain (loss) reclassified from AOCI into interest expense - Interest Rate Contracts $ 0.3 $ (0.4) $ (0.3) $ (1.2) (a) Effective portion, pre-tax (b) Amount reclassified to offset earnings impact of liability hedged by cross currency swap Non-Designated Hedging Activities In addition, the Company utilizes foreign currency forward contracts to mitigate foreign exchange rate risk associated with foreign currency denominated monetary assets and liabilities, including intercompany receivables and payables. As of October 2, 2022, Teledyne had non-designated foreign currency contracts of this type, primarily in the following pairs (in millions): Contracts to Buy Contracts to Sell Currency Amount Currency Amount Canadian Dollars $ 236.1 U.S. Dollars US$ 178.6 Great Britain Pounds £ 89.5 U.S. Dollars US$ 104.9 Euros € 237.4 U.S. Dollars US$ 237.2 Danish Krone DKR 74.6 U.S. Dollars US$ 10.0 Swedish Krona SEK 491.1 Euros € 46.0 U.S. Dollars US$ 15.6 Swedish Krona SEK 168.8 Norwegian Krone kr 214.7 Swedish Krona SEK 231.4 The preceding table includes non-designated hedges derived from terms contained in triggered or previously designated cash flow hedges. The gains and losses on these derivatives which are not designated as hedging instruments are intended to, at a minimum, partially offset the transaction gains and losses recognized in earnings. Teledyne does not use foreign currency forward contracts for speculative or trading purposes. The effect of derivative instruments not designated as cash flow hedges recognized in other income and expense for the third quarter and nine months ended October 2, 2022 was expense of $40.5 million and $70.9 million, respectively. The effect of derivative instruments not designated as cash flow hedges in other income and expense for the third quarter and nine months ended October 3, 2021 was expense of $11.7 million and $16.5 million, respectively. The income or expense was largely offset by losses or gains in the value of the underlying hedged item excluding the impact of forward points. Fair Value of Derivative Financial Instruments The Company has elected to use the income approach to value the derivatives, using observable Level 2 market expectations at measurement date and standard valuation techniques to convert future amounts to a single present amount. Level 2 inputs for the valuations are limited to quoted prices for similar assets or liabilities in active markets and inputs other than quoted prices that are observable for the asset or liability (specifically SOFR and EURIBOR cash and swap rates, foreign currency forward rates and cross currency basis spreads). Mid-market pricing is used as a practical expedient for fair value measurements. The fair value measurement of an asset or liability must reflect the nonperformance risk of the entity and the counterparty. Therefore, the impact of the counterparty’s creditworthiness when in an asset position and the Company’s creditworthiness when in a liability position has also been factored into the fair value measurement of the derivative instruments and did not have a material impact on the fair value of these derivative instruments. Both the counterparty and the Company are expected to continue to perform under the contractual terms of the instruments. The fair values of the Company’s derivative financial instruments are presented below. All fair values for these derivatives were measured using Level 2 information as defined by the accounting standard hierarchy (in millions): Asset/(Liability) Derivatives Balance sheet location October 2, 2022 January 2, 2022 Derivatives designated as hedging instruments: Cash flow forward contracts Other current assets $ — $ 0.3 Cash flow forward contracts Accrued liabilities (12.7) (1.2) Cash flow cross currency swap Other current assets 2.3 3.8 Cash flow cross currency swap Other non-current liabilities (2.5) (9.4) Cash flow cross currency swap Other current assets (accrued interest) 0.1 0.1 Interest rate contracts Other long-term liabilities — (0.1) Interest rate contracts Other current liabilities — (1.2) Interest rate contracts Other current assets 1.3 — Total derivatives designated as hedging instruments (11.5) (7.7) Derivatives not designated as hedging instruments: Non-designated forward contracts Other current assets 2.0 4.7 Non-designated forward contracts Accrued liabilities (19.0) (2.1) Total derivatives not designated as hedging instruments (17.0) 2.6 Total derivatives, net $ (28.5) $ (5.1)

Revenue from Contract with Customer [Abstract]
Customer Contracts	Customer Contracts Estimate at Completion Process For over time contracts using the cost-to-cost method, we have an Estimate at Completion (“EAC”) process in which management reviews the progress and execution of our performance obligations. This EAC process requires management judgment relative to assessing risks, estimating contract revenue and cost, and making assumptions for schedule and technical issues. Since certain contracts extend over multiple reporting periods, the impact of revisions in cost and revenue estimates during the progress of work may adjust the current period earnings through a cumulative catch-up basis. This method recognizes, in the current period, the cumulative effect of the changes on current and prior quarters. Additionally, if the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the period that it becomes evident. Contract cost and revenue estimates for significant contracts are reviewed and reassessed quarterly. The majority of revenue recognized over time uses an EAC process. The net aggregate effects of changes in estimates on contracts accounted for under the cost-to-cost method in the first nine months of 2022 was approximately $30.5 million of favorable operating income, primarily related to favorable changes in estimates that impacted revenue within the Digital Imaging and Aerospace and Defense Electronics segments. The net aggregate effects of changes in estimates on contracts accounted for under the cost-to-cost method in the first nine months of 2021 was approximately $16.9 million of favorable operating income, primarily related to favorable changes in estimates that impacted revenue within the Digital Imaging operating segment. None of the effects of changes in estimates on any individual contract were material to the condensed consolidated statements of income for any period presented. Contract Liabilities We recognize a liability for interim and advance payments in excess of revenue recognized and present it as a contract liability which is included within accrued liabilities and other long-term liabilities on the condensed consolidated balance sheet, which represented $155.5 million and $21.2 million as of October 2, 2022, and $186.0 million and $25.3 million as of January 2, 2022, respectively, with the decrease in contract liabilities from the beginning of the year due to timing and use of advance payments received on certain contracts within the Digital Imaging and Aerospace and Defense Electronic segments. The Company recognized revenue of $129.6 million during the nine months ended October 2, 2022 from contract liabilities that existed at the beginning of year. The Company recognizes the incremental costs of obtaining or fulfilling a contract as expense when incurred if the amortization period of the asset is one year or less. Incremental costs to obtain or fulfill contracts with an amortization period greater than one year were not material. Remaining Performance Obligations Remaining performance obligations represent the transaction price of firm orders for which work has not been performed as of the period end date and excludes unexercised contract options and potential orders under ordering-type contracts (e.g., indefinite-delivery, indefinite-quantity). As of October 2, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was $3,188.5 million. The Company expects approximately 73% of remaining performance obligations to be recognized into revenue within the next twelve months, with the remaining 27% recognized thereafter. Product Warranty Costs Some of the Company’s products are subject to specified warranties, and the Company provides for the estimated cost of product warranties. The adequacy of the warranty reserve is assessed regularly, and the reserve is adjusted as necessary based on a review of historic warranty experience with respect to the applicable business or products, as well as the length and actual terms of the warranties. The warranty reserve is included in current and long-term accrued liabilities on the Condensed Consolidated Balance Sheet.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax provision is calculated using an estimated annual effective tax rate, based upon expected annual income, permanent items, statutory rates and planned tax strategies in the various jurisdictions in which the Company operates. However, losses in certain jurisdictions and discrete items, such as the resolution of uncertain tax positions, are treated separately. The Company’s effective income tax rate for the third quarter and first nine months of 2022 was 23.0% and 14.3%, respectively. The Company's effective income tax rate for the third quarter and first nine months of 2021 was 20.1% and 21.5%, respectively. The third quarter of 2022 includes net discrete income tax benefits of $0.3 million compared with net discrete income tax benefits of $6.3 million. The first nine months of 2022 includes net discrete income tax benefits of $57.8 million compared with net discrete income tax benefits of $8.5 million. The third quarter and first nine months of 2022 net discrete income tax amounts include $0.2 million and $8.7 million, respectively, related to share-based accounting. The third quarter and first nine months of 2022 also includes non-cash income tax benefits of $0.1 million and non-cash income tax benefits of $49.1 million, with the first nine months of 2022 primarily related to the resolution of certain FLIR tax reserves. The third quarter and first nine months of 2021 net discrete income tax amounts include $3.0 million and $9.9 million, respectively, related to share-based accounting. The third quarter and first nine months of 2021 net discrete income tax amounts also include income tax benefits of $4.9 million primarily related to research and development and foreign tax credits. The first nine months of 2021 net discrete income tax amounts also include $11.5 million expense related to foreign tax rate changes and a $5.3 million income tax benefit related to the release of a valuation allowance. The 2021 foreign tax rate changes are a result of the United Kingdom Parliament enacting legislation to increase the corporate tax rate to 25% effective April 2023. Excluding the net discrete income tax items in both periods, the effective tax rates would have been 23.1% for the

Commitments and Contingencies Disclosure [Abstract]
Lawsuits, Claims, Commitments, Contingencies and Related Matters	Lawsuits, Claims, Commitments, Contingencies and Related Matters For a further description of the Company’s commitments and contingencies, reference is made to Note 14 of the Company’s financial statements as of and for the fiscal year ended January 2, 2022, included in the 2021 Form 10-K. At October 2, 2022, the Company’s reserves for environmental remediation obligations totaled $5.9 million, of which $1.6 million is included in current accrued liabilities. At January 2, 2022, the Company’s reserves for environmental remediation obligations totaled $6.3 million. The Company 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 30 years. Effective April 24, 2022, the United States Department of State’s Office of Defense Trade Controls Compliance (“DDTC”) closed the four-year Consent Agreement that had been entered into by FLIR Systems, Inc., on April 24, 2018, 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 the International Traffic in Arms Regulations (“ITAR”). On April 13, 2022, Teledyne paid $3.5 million as the final installment of the civil penalty under the Consent Agreement. While FLIR and its successor by mergers, Teledyne FLIR, have enhanced the trade compliance program more broadly, implemented remedial measures and have undergone external audits of the ITAR compliance program, future adverse disclosures and findings could cause incurrence of additional expenses in connection with implementation of remedial measures. 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. On April 22, 2022, BIS closed this voluntary disclosure with the issuance of a Warning Letter to Teledyne FLIR, LLC. 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 was completed and a voluntary disclosure was filed in October 2021 to report potential violations. The second internal audit was completed in October 2022. FLIR and its successor by mergers, Teledyne FLIR, have made other voluntary disclosures to the U.S. Department of State and the U.S. Department of Commerce, including to BIS with respect to the shipments of products by FLIR from non-U.S. jurisdictions which were not licensed due to incorrect de minimis calculation methodology, as well as to other non-U.S. government agencies. If FLIR and now Teledyne FLIR, as its successor by mergers, is found to have violated applicable rules and regulations with respect to customers and limitations on the export and end use of its products or other trade compliance matters, Teledyne 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 the above-described open 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.
