Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Fiscal Year The Company operates on a 52- or 53-week fiscal year convention ending on the Sunday nearest to December 31. Fiscal year 2023 was a 52-week fiscal year and ended on December 31, 2023. Fiscal year 2022 was a 52-week fiscal year and ended on January 1, 2023. Fiscal year 2021 was a 52-week fiscal year and ended on January 2, 2022. References to the years 2023, 2022 and 2021 are intended to refer to the respective fiscal year unless otherwise noted. Principles of Consolidation The consolidated financial statements include the accounts of Teledyne and its majority-owned subsidiaries. Intercompany accounts and intercompany transactions have been eliminated. Business Acquisitions Business acquisitions are accounted for under the acquisition method by assigning the purchase price to tangible and intangible assets acquired and liabilities assumed. Assets acquired and liabilities assumed are recorded at their fair values and the excess of the purchase price over the amounts assigned is recorded as goodwill. Foreign Currency Translation The Company’s foreign entities’ accounts are generally measured using local currency as the functional currency. Assets and liabilities of these entities are translated at the exchange rate in effect at year-end. Revenues and expenses are translated at average month end rates of exchange prevailing during the year. Unrealized translation gains and losses arising from differences in exchange rates from period to period are included as a component of accumulated other comprehensive income (loss) (“AOCI”). Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to sales returns and allowances, allowance for doubtful accounts, inventories, goodwill, intangible assets, asset valuations, income taxes, warranty obligations, pension and other postretirement benefits, long-term contracts, environmental, workers’ compensation and general liability, employee benefits and other contingencies and litigation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances at the time, the results of which form the basis for making its judgments. Actual results may differ materially from these estimates under different assumptions or conditions. Management believes that the estimates used are reasonable. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and highly liquid money-market mutual funds with maturities of three months or less when purchased. Accounts Receivable, Contract Assets and Contract Liabilities The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities). Under the typical payment terms of the Company’s over time contracts, the customer pays the Company either performance-based payments or progress payments. Amounts billed and due from the Company’s customers are classified as receivables on the consolidated balance sheets. The Company may receive interim payments as work progresses, although for some contracts, the Company may be entitled to receive an advance payment. The Company recognizes a liability for these interim and advance payments in excess of revenue recognized and present it as a contract liability. Contract liabilities typically are not considered a significant financing component because these cash advances are used to meet working capital demands that can be higher in the early stages of a contract, and these cash advances protect us from the other party failing to adequately complete some or all of its obligations under the contract. When revenue recognized exceeds the amount billed to the customer, the Company records an unbilled receivable (contract asset) for the amount entitled to be received based on an enforceable right to payment. The Company evaluates the collectability of its accounts receivable and contract assets based on a combination of factors, and judgment is required in the estimation process. If the Company becomes aware of a customer’s inability to meet its financial obligations, a specific allowance is recorded to reduce the net receivable to the amount reasonably believed to be collectible from the customer. For all other customers, the Company uses an aging schedule and recognizes allowances for doubtful accounts based on the creditworthiness of the debtor, the age and status of outstanding receivables, the current business environment and historical collection experience adjusted for current expectations for the customers or industry. Accounts receivable are written off against the allowance for uncollectible accounts when the Company determines amounts are no longer collectible. Trade credit is extended based upon evaluations of each customer’s ability to perform its obligations, which are updated periodically. Inventories Inventories are stated at the lower of cost or net realizable value and primarily valued on an average cost or first-in, first-out method. Inventory adjustments are recorded when inventory is considered to be excess or obsolete based upon an analysis of actual on-hand quantities on a part-level basis to forecasted product demand and historical usage. Property, Plant and Equipment Property, plant and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are determined using a combination of accelerated and straight-line methods over the estimated useful lives of the various asset classes. Buildings and building improvements are depreciated over periods not exceeding 45 years, equipment over 5 to 18 years, computer hardware and software over 3 to 7 years and leasehold improvements over the shorter of the estimated remaining lives or lease terms. Significant improvements are capitalized while maintenance and repairs are charged to expense as incurred. Depreciation expense on property, plant and equipment was $119.1 million in 2023, $129.8 million in 2022 and $115.2 million in 2021. Goodwill, Acquired Intangible Assets and Other Long-Lived Assets Goodwill and acquired intangible assets with indefinite lives are not amortized but tested at least annually for impairment. The Company performs an annual impairment test for goodwill and other indefinite-lived intangible assets in the fourth quarter of each year, or more often as circumstances require. The Company uses qualitative and quantitative approaches when testing goodwill for impairment. For selected reporting units under the qualitative approach, the Company performs a qualitative evaluation of events and circumstances impacting the reporting unit to determine the likelihood of goodwill impairment. Based on that qualitative evaluation, if the Company determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, no further evaluation is necessary. Otherwise, the Company performs a quantitative impairment test. A quantitative impairment test, if applicable, is used to identify potential goodwill impairment and then measure the amount of goodwill impairment loss, if any. The Company performs quantitative tests for reporting units at least once every three years. However, for certain reporting units the Company may perform a quantitative impairment test more frequently. The Company performed a quantitative impairment test for all of its reporting units in 2023. The Company reviews intangible and other long-lived assets subject to depreciation or amortization for impairment whenever events or circumstances indicate that the carrying value of the asset may not be recoverable. Acquired intangible assets with finite lives are amortized and reflected in the segment’s operating income over their estimated useful lives. The Company assesses the recoverability of the carrying value of assets held for use based on a review of projected undiscounted cash flows. Impairment losses, where identified, are determined as the excess of the carrying value over the estimated fair value of the long-lived asset, and reflected in selling, general and administrative expense at the respective business segment. Pension and Postretirement Costs The Company’s accounting for its defined benefit pension plans requires that amounts recognized in financial statements be determined on an actuarial basis, rather than as contributions are made to the plan. In consultation with actuaries, the Company determines the appropriate assumptions for use in determining the liability for future pension benefits. Net actuarial gains or losses are amortized to expense on a plan-by-plan basis when they exceed the accounting corridor. The accounting corridor is a defined range within which amortization of net gains and losses is not required and is equal to 10% of the greater of the market-related value of assets or benefit obligations. Gains or losses outside of the corridor are subject to amortization. Product Warranties Some of the Company’s products are subject to standard warranties, and the Company reserves for the estimated cost of product warranties on a product-specific basis. Facts and circumstances related to a product warranty matter and cost estimates to return, repair and/or replace the product are considered when establishing a product warranty reserve. The adequacy of preexisting warranty reserves is assessed regularly, and the reserve is adjusted as necessary based on a review of historical warranty experience with respect to the applicable business or products, as well as the length and actual terms of the warranties, which are typically one year. The product warranty reserve is included in current accrued liabilities and long-term liabilities on the consolidated balance sheets. Environmental Liabilities Costs that mitigate or prevent future environmental contamination or extend the life, increase the capacity or improve the safety or efficiency of property utilized in current operations are capitalized. Other costs that relate to current operations or an existing condition caused by past operations are expensed in the period incurred. Environmental liabilities are recorded when the Company’s liability is probable and the costs are reasonably estimable, which is generally not later than the completion of the feasibility study or the Company’s recommendation of a remedy or commitment to an appropriate plan of action. The accruals are reviewed periodically and, as investigations and remediations proceed, adjustments are made as necessary. Accruals for losses from environmental remediation obligations do not consider the effects of inflation, and anticipated expenditures are not discounted to their present value. The accruals are not reduced by possible recoveries from insurance carriers or other third parties but do reflect anticipated allocations among potentially responsible parties at federal Superfund sites or similar state-managed sites and an assessment of the likelihood that such parties will fulfill their obligations at such sites. The measurement of environmental liabilities by the Company is based on currently available facts, present laws and regulations, and current technology. Such estimates take into consideration the Company’s prior experience in site investigation and remediation, the data concerning cleanup costs available from other companies and regulatory authorities, and the professional judgment of the Company’s environmental personnel in consultation with outside environmental specialists, when necessary. Revenue Recognition The Company determines the appropriate method by which it recognizes revenue by analyzing the nature of the products or services being provided as well as the terms and conditions of contracts or arrangements entered into with our customers. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A contract’s transaction price is allocated to each distinct good or service (i.e., performance obligation) identified in the contract, and each performance obligation is valued based on its estimated relative standalone selling price. For standard products or services, list prices generally represent the standalone selling price. For performance obligations where list price is not available, the Company typically uses the expected cost plus a margin approach to estimate the standalone selling price for that performance obligation. Approximately 70% of revenue is recognized at a point in time, with the remaining 30% recognized over time. Revenue recognized at a point in time relates primarily to the sale of standard or minimally customized products, with control transferring to the customer generally upon the transfer of title. This type of revenue arrangement is typical for our commercial contracts within the Digital Imaging, Instrumentation, and Aerospace and Defense Electronics segments. In limited circumstances, customer specified acceptance criteria exist. If the Company cannot objectively demonstrate that the product meets those specifications prior to the shipment, the revenue is deferred until customer acceptance is obtained. The transaction price in these arrangements can include variable consideration, such as product returns and sales allowances. The estimation of this variable consideration and determination of whether to include estimated amounts as a reduction in the transaction price is based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company. Revenue recognized over time relates primarily to contracts to design, develop and/or manufacture highly engineered products used in both defense and commercial applications. This type of revenue arrangement is typical of the Company’s U.S. Government contracts and to a lesser extent for certain commercial contracts, with both contract types occurring across all segments. The customer typically controls the work in process as evidenced either by contractual termination clauses or by a right to payment for costs incurred to date plus a reasonable profit for products or services that do not have an alternative use. As control transfers continuously over time on these contracts, revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company generally uses the cost-to-cost measure of progress as this measure best depicts the transfer of control to the customer which occurs as the Company incurs costs on contracts. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The transaction price in these arrangements may include estimated amounts of variable consideration, including award fees, incentive fees, contract amounts not yet funded, or other provisions that can either increase or decrease the transaction price. The Company estimates variable consideration at the amount to which it expects to be entitled, and the Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the estimation uncertainty is resolved. The estimation of this variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. The majority of the Company’s over time contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Over time contracts are often modified to account for changes in contract specifications and requirements. The Company considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of the contract modifications on the Company’s over time contracts are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and the measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. For over time contracts using the cost-to-cost method, the Company has 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, determining reasonably dependable cost estimates, and making assumptions for schedule and technical issues. Since certain contracts extend over a longer period of time, 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 generally reviewed and reassessed quarterly. The majority of revenue recognized over time uses an EAC process. The net aggregate effects of these changes in estimates on contracts accounted for under the cost-to-cost method in 2023 and 2022 was approximately $3.7 million of favorable operating income and $29.9 million of favorable operating income, respectively. The 2022 amount related to favorable changes in estimates that impacted revenue, and, to a lesser degree, cost of sales within the Digital Imaging operating segment. None of the effects of changes in estimates on any individual contract were material to the consolidated statements of income for any period presented. While extended or non-customary warranties do not represent a significant portion of the Company’s revenue, the Company recognizes warranty services as a separate performance obligation when it is material to the contract. When extended or non-customary warranties represents a separate performance obligation, the revenue is deferred and recognized ratably over the extended warranty period. 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. Shipping and Handling Shipping and handling fees reimbursed by customers are classified as revenue while shipping and handling costs incurred by the Company are classified as cost of sales in the accompanying consolidated statements of income. Research and Development and Bid and Proposal Costs Selling, general and administrative expenses include research and development and bid and proposal costs which are expensed as incurred and were $365.8 million in 2023, $360.6 million in 2022 and $299.3 million in 2021. The 2021 amount includes a partial year of Teledyne FLIR research and development costs due to the timing of the acquisition. Leases The Company determines if an arrangement is a lease at inception. Operating leases are recorded as right-of-use assets in noncurrent other assets, net and the related lease liabilities in accrued liabilities and other long-term liabilities. The Company does not have material finance leases or subleases. Operating lease right-of-use assets represent a right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. Operating lease right-of-use assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term and use an implicit rate when readily available. Since most of the Company’s leases do not provide an implicit rate, the Company uses the incremental borrowing rate to determine the present value of lease payments. The rate will take into consideration the underlying asset’s economic environment, including the length of the lease term and currency that the lease is payable in. The Company’s lease agreements may include options to extend or early terminate the lease term at either a fixed cost, fixed increase or market value adjustment. The Company evaluates the likelihood of exercising each renewal option based on many factors, including the length of the renewal option and the future new lease cost, if known, or the estimated future new lease cost if it is not a fixed amount and will include those renewal options that are reasonably certain to be exercised for purposes of calculating the lease liability and corresponding right-of-use asset. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Stock Incentive Plans Teledyne has long-term incentive plans which provide its Board of Directors the flexibility to grant restricted stock, restricted stock units, non-qualified stock options, incentive stock options and stock appreciation rights to officers and employees of Teledyne. During 2023, 2022 and 2021, the Company has granted time-based stock options, time-based restricted stock unit awards, and performance-based restricted stock unit awards. Employee stock options become exercisable in one-third increments on the first, second and third anniversary of the grant and have a maximum 10-year life. Employee time-based restricted stock units vest in one-third increments on the first, second and third anniversary of the grant. Performance-based restricted stock awards granted during 2023, 2022 and 2021 may be earned based upon a time-based component and the performance of the Company’s return to stockholders over a three-year period. In 2021, the Company discontinued the Performance Share Plan (“PSP”), with an immaterial amount of compensation expense recorded in 2023 and 2022. Teledyne’s PSP provided grants of performance share units, which key officers and executives could earn if Teledyne met specified performance objectives over a three-year period. Awards were payable in cash and to the extent available, shares of Teledyne common stock. Stock-based Compensation Costs The Company recognizes compensation expense for its stock-based compensation programs, which include stock options, restricted stock and restricted stock units (RSUs). The fair value of share-based compensation is determined at the grant date and the recognition of the related expense is generally recorded over the period in which the share-based compensation vests. Since 2019, stock options granted to our Executive Chairman are expensed immediately, as stock options continue to vest after retirement. The Company issues shares of common stock upon the exercise of stock options. The fair value of stock options granted through 2022 was determined by using a lattice-based option pricing model, and the Company did not grant stock options in 2023. In recent years, the Company began granting stock options to a smaller group of employees, as the Company began granting restricted stock units to a larger group of employees. In 2024, the Company began using the Black-Scholes option pricing model to determine the fair value of stock options. The Company uses a combination of its historical stock price volatility and the volatility of exchange traded options, if any, on the Company stock to compute the expected volatility for purposes of valuing stock options granted. The period used for the historical stock price corresponded to the expected term of the options. The period used for the exchange traded options, if any, included the longest-dated options publicly available, generally three months. The expected dividend yield is based on Teledyne’s practice of not paying dividends. The risk-free rate of return is based on the yield of U.S. Treasury Strips with terms equal to the expected life of the options as of the grant date. The expected life in years is based on historical actual stock option exercise experience. Treasury Stock In January 2016, the Company’s Board of Directors authorized a stock repurchase program authorizing the Company to repurchase up to 3,000,000 shares of its common stock. The number of shares that the Company may repurchase will depend on a variety of factors, such as share price, levels of cash and borrowing capacity available, alternative investment opportunities available immediately or longer-term, and other regulatory, market or economic conditions. Although the Company has no current plans to repurchase stock, future repurchases, if any, are expected to be funded with cash on hand and borrowings under the Company’s credit facility. No repurchases were made since 2015. Preferred Stock Authorized preferred stock may be issued with designations, powers and preferences designated by the Board of Directors. There were no shares of preferred stock issued or outstanding in 2023, 2022 or 2021. Redeemable Noncontrolling Interest The minority ownership interest in shares of NL Acoustics is classified as a redeemable noncontrolling interest on the consolidated balance sheets due to a put option under which the minority owners 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. Income Taxes The Company is subject to income taxes in the Unites States and numerous foreign jurisdictions. The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for temporary differences between the tax basis of assets and liabilities and their reported amount in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating the Company’s ability to recover its deferred tax assets within the jurisdiction from which they arise, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, the Company begins with historical results adjusted for the results of discontinued operations and incorporate assumptions about the amount of future state, federal and foreign pretax operating income adjusted for items that do not have tax consequences. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates the Company is using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, the Company considers three years of cumulative operating income. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. Income tax positions must meet a more-likely-than-not recognition in order to be recognized in the financial statements. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits as income tax expense. As new information becomes available, the assessment of the recognition threshold and the measurement of the associated tax benefit of uncertain tax positions may result in financial statement recognition or derecognition. Earnings Per Common Share Basic and diluted earnings per common share are computed based on net income (loss) attributable to Teledyne. The weighted average number of common shares outstanding during the period is used in the calculation of basic earnings per share. This number of shares is increased by contingent shares that could be issued under various compensation plans as well as by the dilutive effect of stock options based on the treasury stock method in the calculation of diluted earnings per common share. Derivative Instruments and Hedging Activities 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 objective is to protect the U.S. dollar value of future cash flows and minimize the volatility of reported earnings. The Company’s foreign currency objective is achieved through the following: •The Company utilizes foreign currency forward contracts to reduce the volatility of cash flows primarily related to forecasted revenue and expenses denominated in Canadian dollars for our Canadian companies, and in British pounds for our U.K. companies. These contracts are designated and qualify as cash flow hedges. •The Company has converted a U.S. dollar denominated, variable rate and fixed rate debt obligation of a European subsidiary, into euro fixed rate obligation using a receive float, pay fixed cross currency swap, and a receive fixed, pay fixed cross currency swap. This cross currency swap is designated as a cash flow hedge. •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. The effectiveness of the cash flow hedge forward contracts is assessed prospectively and retrospectively on a monthly basis 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 must be highly effective in offsetting changes to future cash flows on hedged transactions. The effective portion of the cash flow hedge 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 consolidated statements of income, at which time the effective amount in AOCI is reclassified to revenue in our consolidated statements of income. 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 and 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, due to missed forecasts. Fair Value Measurements Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The Company considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. The fair value hierarchy comprises three levels. Level 1 relates to quoted prices in active markets for identical assets or liabilities. Level 2 relates to observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 are unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy; for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is disclosed is determined based on the lowest level input that is significant to the fair value measurement. Related Party Transactions For all periods presented, the Company had no material related party transactions that required disclosure. Recent Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This standard requires a public entity to disclose significant segment expenses and other segment items on an interim and annual basis. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker (“CODM”). The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction focuses on the rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements. Other ASU’s issued but not effective until after December 31, 2023 are not expected to have a material effect on the Company’s consolidated financial position, annual results of operations and/or cash flows.

The Company operates on a 52- or 53-week fiscal year convention ending on the Sunday nearest to December 31. Fiscal year 2023 was a 52-week fiscal year and ended on December 31, 2023. Fiscal year 2022 was a 52-week fiscal year and ended on January 1, 2023. Fiscal year 2021 was a 52-week fiscal year and ended on January 2, 2022. References to the years 2023, 2022 and 2021 are intended to refer to the respective fiscal year unless otherwise noted.

The Company’s foreign entities’ accounts are generally measured using local currency as the functional currency. Assets and liabilities of these entities are translated at the exchange rate in effect at year-end. Revenues and expenses are translated at average month end rates of exchange prevailing during the year. Unrealized translation gains and losses arising from differences in exchange rates from period to period are included as a component of accumulated other comprehensive income (loss) (“AOCI”).

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to sales returns and allowances, allowance for doubtful accounts, inventories, goodwill, intangible assets, asset valuations, income taxes, warranty obligations, pension and other postretirement benefits, long-term contracts, environmental, workers’ compensation and general liability, employee benefits and other contingencies and litigation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances at the time, the results of which form the basis for making its judgments. Actual results may differ materially from these estimates under different assumptions or conditions. Management believes that the estimates used are reasonable.

(contract assets), and customer advances and deposits (contract liabilities). Under the typical payment terms of the Company’s over time contracts, the customer pays the Company either performance-based payments or progress payments. Amounts billed and due from the Company’s customers are classified as receivables on the consolidated balance sheets. The Company may receive interim payments as work progresses, although for some contracts, the Company may be entitled to receive an advance payment. The Company recognizes a liability for these interim and advance payments in excess of revenue recognized and present it as a contract liability. Contract liabilities typically are not considered a significant financing component because these cash advances are used to meet working capital demands that can be higher in the early stages of a contract, and these cash advances protect us from the other party failing to adequately complete some or all of its obligations under the contract. When revenue recognized exceeds the amount billed to the customer, the Company records an unbilled receivable (contract asset) for the amount entitled to be received based on an enforceable right to payment.

The Company evaluates the collectability of its accounts receivable and contract assets based on a combination of factors, and judgment is required in the estimation process. If the Company becomes aware of a customer’s inability to meet its financial obligations, a specific allowance is recorded to reduce the net receivable to the amount reasonably believed to be collectible from the customer. For all other customers, the Company uses an aging schedule and recognizes allowances for doubtful accounts based on the creditworthiness of the debtor, the age and status of outstanding receivables, the current business environment and historical collection experience adjusted for current expectations for the customers or industry. Accounts receivable are written off against the allowance for uncollectible accounts when the Company determines amounts are no longer collectible. Trade credit is extended based upon evaluations of each customer’s ability to perform its obligations, which are updated periodically.

Inventories are stated at the lower of cost or net realizable value and primarily valued on an average cost or first-in, first-out method. Inventory adjustments are recorded when inventory is considered to be excess or obsolete based upon an analysis of actual on-hand quantities on a part-level basis to forecasted product demand and historical usage.

Property, plant and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are determined using a combination of accelerated and straight-line methods over the estimated useful lives of the various asset classes. Buildings and building improvements are depreciated over periods not exceeding 45 years, equipment over 5 to 18 years, computer hardware and software over 3 to 7 years and leasehold improvements over the shorter of the estimated remaining lives or lease terms. Significant improvements are capitalized while maintenance and repairs are charged to expense as incurred. Depreciation expense on property, plant and equipment was $119.1 million in 2023, $129.8 million in 2022 and $115.2 million in 2021.

Goodwill and acquired intangible assets with indefinite lives are not amortized but tested at least annually for impairment. The Company performs an annual impairment test for goodwill and other indefinite-lived intangible assets in the fourth quarter of each year, or more often as circumstances require. The Company uses qualitative and quantitative approaches when testing goodwill for impairment. For selected reporting units under the qualitative approach, the Company performs a qualitative evaluation of events and circumstances impacting the reporting unit to determine the likelihood of goodwill impairment. Based on that qualitative evaluation, if the Company determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, no further evaluation is necessary. Otherwise, the Company performs a quantitative impairment test. A quantitative impairment test, if applicable, is used to identify potential goodwill impairment and then measure the amount of goodwill impairment loss, if any. The Company performs quantitative tests for reporting units at least once every three years. However, for certain reporting units the Company may perform a quantitative impairment test more frequently. The Company performed a quantitative impairment test for all of its reporting units in 2023.

The Company reviews intangible and other long-lived assets subject to depreciation or amortization for impairment whenever events or circumstances indicate that the carrying value of the asset may not be recoverable. Acquired intangible assets with finite lives are amortized and reflected in the segment’s operating income over their estimated useful lives. The Company assesses the recoverability of the carrying value of assets held for use based on a review of projected undiscounted cash flows. Impairment losses, where identified, are determined as the excess of the carrying value over the estimated fair value of the long-lived asset, and reflected in selling, general and administrative expense at the respective business segment.

The Company’s accounting for its defined benefit pension plans requires that amounts recognized in financial statements be determined on an actuarial basis, rather than as contributions are made to the plan. In consultation with actuaries, the Company determines the appropriate assumptions for use in determining the liability for future pension benefits. Net actuarial gains or losses are amortized to expense on a plan-by-plan basis when they exceed the accounting corridor. The accounting corridor is a defined range within which amortization of net gains and losses is not required and is equal to 10% of the greater of the market-related value of assets or benefit obligations. Gains or losses outside of the corridor are subject to amortization.

Some of the Company’s products are subject to standard warranties, and the Company reserves for the estimated cost of product warranties on a product-specific basis. Facts and circumstances related to a product warranty matter and cost estimates to return, repair and/or replace the product are considered when establishing a product warranty reserve. The adequacy of preexisting warranty reserves is assessed regularly, and the reserve is adjusted as necessary based on a review of historical warranty experience with respect to the applicable business or products, as well as the length and actual terms of the warranties, which are typically one year. The product warranty reserve is included in current accrued liabilities and long-term liabilities on the consolidated balance sheets.

Costs that mitigate or prevent future environmental contamination or extend the life, increase the capacity or improve the safety or efficiency of property utilized in current operations are capitalized. Other costs that relate to current operations or an existing condition caused by past operations are expensed in the period incurred. Environmental liabilities are recorded when the Company’s liability is probable and the costs are reasonably estimable, which is generally not later than the completion of the feasibility study or the Company’s recommendation of a remedy or commitment to an appropriate plan of action. The accruals are reviewed periodically and, as investigations and remediations proceed, adjustments are made as necessary. Accruals for losses from environmental remediation obligations do not consider the effects of inflation, and anticipated expenditures are not discounted to their present value. The accruals are not reduced by possible recoveries from insurance carriers or other third parties but do reflect anticipated allocations among potentially responsible parties at federal Superfund sites or similar state-managed sites and an assessment of the likelihood that such parties will fulfill their obligations at such sites. The measurement of environmental liabilities by the Company is based on currently available facts, present laws and regulations, and current technology. Such estimates take into consideration the Company’s prior experience in site investigation and remediation, the data concerning cleanup costs available from other companies and regulatory authorities, and the professional judgment of the Company’s environmental personnel in consultation with outside environmental specialists, when necessary.

The Company determines the appropriate method by which it recognizes revenue by analyzing the nature of the products or services being provided as well as the terms and conditions of contracts or arrangements entered into with our customers. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A contract’s transaction price is allocated to each distinct good or service (i.e., performance obligation) identified in the contract, and each performance obligation is valued based on its estimated relative standalone selling price. For standard products or services, list prices generally represent the standalone selling price. For performance obligations where list price is not available, the Company typically uses the expected cost plus a margin approach to estimate the standalone selling price for that performance obligation. Approximately 70% of revenue is recognized at a point in time, with the remaining 30% recognized over time.

Revenue recognized at a point in time relates primarily to the sale of standard or minimally customized products, with control transferring to the customer generally upon the transfer of title. This type of revenue arrangement is typical for our commercial contracts within the Digital Imaging, Instrumentation, and Aerospace and Defense Electronics segments. In limited circumstances, customer specified acceptance criteria exist. If the Company cannot objectively demonstrate that the product meets those specifications prior to the shipment, the revenue is deferred until customer acceptance is obtained. The transaction price in these arrangements can include variable consideration, such as product returns and sales allowances. The estimation of this variable consideration and determination of whether to include estimated amounts as a reduction in the transaction price is based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company.

Revenue recognized over time relates primarily to contracts to design, develop and/or manufacture highly engineered products used in both defense and commercial applications. This type of revenue arrangement is typical of the Company’s U.S. Government contracts and to a lesser extent for certain commercial contracts, with both contract types occurring across all segments. The customer typically controls the work in process as evidenced either by contractual termination clauses or by a right to payment for costs incurred to date plus a reasonable profit for products or services that do not have an alternative use. As control transfers continuously over time on these contracts, revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company generally uses the cost-to-cost measure of progress as this measure best depicts the transfer of control to the customer which occurs as the Company incurs costs on contracts. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The transaction price in these arrangements may include estimated amounts of variable consideration, including award fees, incentive fees, contract amounts not yet funded, or other provisions that can either increase or decrease the transaction price. The Company estimates variable

consideration at the amount to which it expects to be entitled, and the Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the estimation uncertainty is resolved. The estimation of this variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.

The majority of the Company’s over time contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Over time contracts are often modified to account for changes in contract specifications and requirements. The Company considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of the contract modifications on the Company’s over time contracts are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and the measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

For over time contracts using the cost-to-cost method, the Company has 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, determining reasonably dependable cost estimates, and making assumptions for schedule and technical issues. Since certain contracts extend over a longer period of time, 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 generally reviewed and reassessed quarterly. The majority of revenue recognized over time uses an EAC process. The net aggregate effects of these changes in estimates on contracts accounted for under the cost-to-cost method in 2023 and 2022 was approximately $3.7 million of favorable operating income and $29.9 million of favorable operating income, respectively. The 2022 amount related to favorable changes in estimates that impacted revenue, and, to a lesser degree, cost of sales within the Digital Imaging operating segment. None of the effects of changes in estimates on any individual contract were material to the consolidated statements of income for any period presented.

While extended or non-customary warranties do not represent a significant portion of the Company’s revenue, the Company recognizes warranty services as a separate performance obligation when it is material to the contract. When extended or non-customary warranties represents a separate performance obligation, the revenue is deferred and recognized ratably over the extended warranty period.

Operating lease right-of-use assets represent a right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. Operating lease right-of-use assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term and use an implicit rate when readily available. Since most of the Company’s leases do not provide an implicit rate, the Company uses the incremental borrowing rate to determine the present value of lease payments. The rate will take into consideration the underlying asset’s economic environment, including the length of the lease term and currency that the lease is payable in. The Company’s lease agreements may include options to extend or early terminate the lease term at either a fixed cost, fixed increase or market value adjustment. The Company evaluates the likelihood of exercising each renewal option based on many factors, including the length of the renewal option and the future new lease cost, if known, or the estimated future new lease cost if it is not a fixed amount and will include those renewal options that are reasonably certain to be exercised for purposes of calculating the lease

Teledyne has long-term incentive plans which provide its Board of Directors the flexibility to grant restricted stock, restricted stock units, non-qualified stock options, incentive stock options and stock appreciation rights to officers and employees of Teledyne. During 2023, 2022 and 2021, the Company has granted time-based stock options, time-based restricted stock unit awards, and performance-based restricted stock unit awards. Employee stock options become exercisable in one-third increments on the first, second and third anniversary of the grant and have a maximum 10-year life. Employee time-based restricted stock units vest in one-third increments on the first, second and third anniversary of the grant. Performance-based restricted stock awards granted during 2023, 2022 and 2021 may be earned based upon a time-based component and the performance of the Company’s return to stockholders over a three-year period.

In 2021, the Company discontinued the Performance Share Plan (“PSP”), with an immaterial amount of compensation expense recorded in 2023 and 2022. Teledyne’s PSP provided grants of performance share units, which key officers and executives could earn if Teledyne met specified performance objectives over a three-year period. Awards were payable in cash and to the extent available, shares of Teledyne common stock.

The Company recognizes compensation expense for its stock-based compensation programs, which include stock options, restricted stock and restricted stock units (RSUs). The fair value of share-based compensation is determined at the grant date and the recognition of the related expense is generally recorded over the period in which the share-based compensation vests. Since 2019, stock options granted to our Executive Chairman are expensed immediately, as stock options continue to vest after retirement. The Company issues shares of common stock upon the exercise of stock options.

The fair value of stock options granted through 2022 was determined by using a lattice-based option pricing model, and the Company did not grant stock options in 2023. In recent years, the Company began granting stock options to a smaller group of employees, as the Company began granting restricted stock units to a larger group of employees. In 2024, the Company began using the Black-Scholes option pricing model to determine the fair value of stock options. The Company uses a combination of its historical stock price volatility and the volatility of exchange traded options, if any, on the Company stock to compute the expected volatility for purposes of valuing stock options granted. The period used for the historical stock price corresponded to the expected term of the options. The period used for the exchange traded options, if any, included the longest-dated options publicly available, generally three months. The expected dividend yield is based on Teledyne’s practice of not paying dividends. The risk-free rate of return is based on the yield of U.S. Treasury Strips with terms equal to the expected life of the options as of the grant date. The expected life in years is based on historical actual stock option exercise experience.

In January 2016, the Company’s Board of Directors authorized a stock repurchase program authorizing the Company to repurchase up to 3,000,000 shares of its common stock. The number of shares that the Company may repurchase will depend on a variety of factors, such as share price, levels of cash and borrowing capacity available, alternative investment opportunities available immediately or longer-term, and other regulatory, market or economic conditions. Although the Company has no current plans to repurchase stock, future repurchases, if any, are expected to be funded with cash on hand and borrowings under the Company’s credit facility. No repurchases were made since 2015.

The minority ownership interest in shares of NL Acoustics is classified as a redeemable noncontrolling interest on the consolidated balance sheets due to a put option under which the minority owners 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.

The Company is subject to income taxes in the Unites States and numerous foreign jurisdictions. The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for temporary differences between the tax basis of assets and liabilities and their reported amount in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating the Company’s ability to recover its deferred tax assets within the jurisdiction from which they arise, the Company considers all available positive and negative evidence, including

scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, the Company begins with historical results adjusted for the results of discontinued operations and incorporate assumptions about the amount of future state, federal and foreign pretax operating income adjusted for items that do not have tax consequences. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates the Company is using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, the Company considers three years of cumulative operating income. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized.

Income tax positions must meet a more-likely-than-not recognition in order to be recognized in the financial statements. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits as income tax expense. As new information becomes available, the assessment of the recognition threshold and the measurement of the associated tax benefit of uncertain tax positions may result in financial statement recognition or derecognition.

Basic and diluted earnings per common share are computed based on net income (loss) attributable to Teledyne. The weighted average number of common shares outstanding during the period is used in the calculation of basic earnings per share. This number of shares is increased by contingent shares that could be issued under various compensation plans as well as by the dilutive effect of stock options based on the treasury stock method in the calculation of diluted earnings per common share.

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 objective is to protect the U.S. dollar value of future cash flows and minimize the volatility of reported earnings. The Company’s foreign currency objective is achieved through the following:

The effectiveness of the cash flow hedge forward contracts is assessed prospectively and retrospectively on a monthly basis 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 must be highly effective in offsetting changes to future cash flows on hedged transactions. The effective portion of the cash flow hedge 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 consolidated statements of income, at which time the effective amount in AOCI is reclassified to revenue in our consolidated statements of income.

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 and 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, due to missed forecasts.

Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The Company considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. The fair value hierarchy comprises three levels. Level 1 relates to quoted prices in active markets for identical assets or liabilities. Level 2 relates to observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 are unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy; for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is disclosed is determined based on the lowest level input that is significant to the fair value measurement.

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This standard requires a public entity to disclose significant segment expenses and other segment items on an interim and annual basis. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker (“CODM”). The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction focuses on the rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements.
