NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

June 28, 2020

Note 1. 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 accounting principles generally accepted 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 December 29, 2019 (“2019 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 June 28, 2020 and the consolidated results of operations, consolidated comprehensive income for the second quarter and six months then ended and the consolidated cash flows for the six months then ended. The results of operations and cash flows for the periods ended June 28, 2020 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 related to the segment realignment in the third quarter of 2019.

Cash Equivalents

Cash equivalents consist of highly liquid money-market mutual funds and bank deposits with maturities of three months or less when purchased. Cash equivalents totaled $203.0 million at June 28, 2020. There were no cash equivalents at December 29, 2019.

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the computation of the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record a goodwill impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. We adopted the new guidance as of December 30, 2019 which reduced the complexity surrounding the evaluation of goodwill for impairment. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The standard replaces the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires the use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. The standard requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We adopted the new guidance as of December 30, 2019 using the modified retrospective approach related to our accounts receivables and contract assets, resulting in no cumulative adjustment to retained earnings. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.

Note 3. Business Combinations, Goodwill and Acquired Intangible Assets

Acquisition of the OakGate Technology, Inc.

On January 5, 2020, we acquired OakGate Technology, Inc. (“OakGate”) for $28.5 million in cash, net of cash acquired. Based in Loomis, California, OakGate provides software and hardware designed to test electronic data storage devices from development through manufacturing and end-use applications. The acquired business is part of the Test and Measurement product line of the Instrumentation segment.

Acquisition of Micralyne, Inc.

On August 30, 2019, we acquired Micralyne Inc. for $26.2 million in cash, net of cash acquired and including a $0.5 million purchase price adjustment paid in January 2020. Based in Edmonton, Alberta, Canada, Micralyne is a privately-owned foundry providing Micro Electro Mechanical Systems or MEMS devices. In particular, Micralyne possesses unique microfluidic technology for biotech applications, as well as capabilities in non-silicon-based MEMS (e.g. gold, polymers) often required for human body compatibility. The acquired business is part of the Digital Imaging segment.

Acquisition of the gas and flame detection business of 3M Company

On August 1, 2019, we acquired the gas and flame detection business of 3M Company for $233.5 million in cash, net of cash acquired. The gas and flame detection business includes Oldham, Simtronics, Gas Measurement Instruments, Detcon and select Scott Safety products. The gas and flame detection business provides a portfolio of fixed and portable industrial gas and flame detection instruments used in a variety of industries including petrochemical, power generation, oil and gas, food and beverage, mining and waste water treatment. Principally located in France, the United Kingdom and the United States, the acquired business is part of the Environmental product line of the Instrumentation segment.

Acquisition of the scientific imaging businesses of Roper Technologies, Inc.

On February 5, 2019, we acquired the scientific imaging businesses of Roper Technologies, Inc. for $224.8 million in cash, net of cash acquired and including a purchase price adjustment. Principally located in the United States and Canada, the acquired businesses are part of the Digital Imaging segment. The acquired businesses include Princeton Instruments, Photometrics and Lumenera. The acquired businesses provide a range of imaging solutions, primarily for life sciences, academic research and customized OEM industrial imaging solutions. Princeton Instruments and Photometrics manufacture state-of-the-art cameras, spectrographs and optics for advanced research in physical sciences, life sciences research and spectroscopy imaging. Applications and markets include materials analysis, quantum technology and cell biology imaging using fluorescence and chemiluminescence. Lumenera primarily provides rugged USB-based customized cameras for markets such as traffic management, as well as life sciences applications.

Goodwill and Acquired Intangible Assets

Teledyne’s goodwill was $2,061.3 million at June 28, 2020 and $2,050.5 million at December 29, 2019. The increase in the balance of goodwill in 2020 resulted from goodwill from recent acquisitions, mostly offset by exchange rate changes. Goodwill resulting from the acquisition of OakGate will not be deductible for tax purposes. Teledyne’s net acquired intangible assets were $409.2 million at June 28, 2020 and $430.8 million at December 29, 2019. The decrease in the balance of net acquired intangible assets resulted from amortization of acquired intangible assets and exchange rate changes. The Company completed the process of specifically identifying the amount to be assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the scientific imaging businesses acquisition. The Company is in the process of specifically identifying the amount to be assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the OakGate acquisition and the gas and flame detection business and the Micralyne acquisitions since there was insufficient time between the acquisition dates and the end of the period to finalize the analysis.

During the second quarter of 2020, the Company evaluated the effects of the COVID-19 pandemic and its negative impact on the global economy on each of the Company’s reporting units and indefinite-lived intangible assets. Management reviewed key assumptions, including revisions of projected future revenues for reporting units and the results of the previous annual impairment testing performed during the fourth quarter of 2019. The Company did not identify an indication of impairment for each of its reporting units and indefinite-lived intangible assets. Although it was determined that a triggering event had not occurred as of June 28, 2020, we will continue to monitor the impacts of the COVID-19 pandemic on the Company’s reporting units and indefinite-lived intangible assets.

Teledyne funded the acquisitions with borrowings under its credit facility and cash on hand. The results of each acquisition have been included in Teledyne’s results since the date of each respective acquisition.

Note 4. 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 a U.S. dollar denominated, variable rate obligation into a euro fixed rate obligation using a receive float, 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.

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 consolidated statements of income, at which time the effective amount in AOCI is

reclassified to revenue in our 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 $0.9 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 $2.0 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 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.

As of June 28, 2020, Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $93.1 million. These foreign currency forward contracts have maturities ranging from September 2020 to May 2021. Teledyne had foreign currency forward contracts designated as cash flow hedges to buy British pounds and to sell U.S. dollars totaling $6.5 million. These foreign currency forward contracts have maturities ranging from September 2020 to February 2021. The cross currency swaps have notional amounts of €113.0 million and $125 million, and €135.0 million and $150.0 million, and matures in March 2023 and October 2024, respectively. The interest rate swap has a notional amount of $125.0 million and matures in March 2023.

The effect of derivative instruments designated as cash flow hedges in the condensed consolidated financial statements for the second quarter and six months ended June 28, 2020 and June 30, 2019 was as follows (in millions):

	Second Quarter				Six Months

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 June 28, 2020, Teledyne had non-designated foreign currency contracts, (in excess of approximately $311.2 million) of this type in the following pairs (in millions):

Contracts to Buy			Contracts to Sell
Currency	Amount		Currency	Amount
Canadian Dollars	$	51.0	U.S. Dollars	US$	37.6
Canadian Dollars	$	15.1	Euros	€	9.9
Great Britain Pounds	£	61.8	U.S. Dollars	US$	76.9
Euros	€	31.0	U.S. Dollars	US$	34.8
Danish Krone	DKR	139.4	U.S. Dollars	US$	21.0
Great Britain Pounds	£	5.9	Euros	€	6.6

The above 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 second quarter and six months ended June 28, 2020 was income of $1.8 million and expense of $8.6 million, respectively.. The effect of derivative instruments not designated as cash flow hedges in other income and expense for the second quarter and six months

10

ended June 30, 2019 was expense of $0.7 million and income of $0.9 million, respectively. The income/expense was largely offset by losses/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 (specifically futures contracts on LIBOR and EURIBOR) and inputs other than quoted prices that are observable for the asset or liability (specifically LIBOR 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	June 28, 2020		December 29, 2019

Note 5. Earnings Per Share

For the second quarter of 2020 and first six months of 2020, 241,931 and 244,192 stock options, respectively, were excluded in the computation of diluted earnings per share because they had exercise prices that were greater than the weighted average market price of the Company’s common stock during the respective periods. For the second quarter of 2019, no stock options were excluded in the computation of earnings per share. For the first six months of 2019, 3,240 stock options were excluded in the computation of diluted earnings per share because they had exercise prices that were greater than the weighted average market price of the Company’s common stock during the period. The weighted average number of common shares used in the calculation of basic and diluted earnings per share consisted of the following (in millions):

	Second Quarter		Six Months
	2020	2019	2020	2019
Weighted average basic common shares outstanding	36.7	36.2	36.6	36.2
Effect of dilutive securities (primarily stock options)	1.1	1.2	1.2	1.1
Weighted average diluted common shares outstanding	37.8	37.4	37.8	37.3

Note 6. Stock-Based Compensation Plans

Teledyne has long-term incentive plans pursuant to which it has granted non-qualified stock options, restricted stock and performance shares to certain employees. The Company also has non-employee Board of Director stock compensation plans, pursuant to which common stock, stock options and restricted stock units have been issued to its directors.

Stock Incentive Plan

Stock option compensation expense was $5.7 million for the second quarter of 2020 and was $5.8 million for the second quarter of 2019. Stock option compensation expense was $13.1 million for the first six months of 2020 and was $14.7 million for the first six months of 2019. Employee stock option grants are charged to expense evenly over the three year vesting period except for stock options that were granted after 2018 to Teledyne’s Executive Chairman and Teledyne’s President and Chief Executive Officer which were expensed immediately. For 2020, the Company currently expects approximately $25.2 million in stock option compensation expense based on stock options outstanding at June 28, 2020. This amount can be impacted by employee retirements and terminations or stock options granted during the remainder of the year. The Company issues shares of common stock upon the exercise of stock options.

The following assumptions were used in the valuation of stock options granted in the first six months of 2020:

	2020
Expected volatility	23.7%
Risk-free interest rate range	1.50% to 1.75%
Expected life in years	6.6
Expected dividend yield	—

Based on the assumptions used in the valuation of stock options, the grant date weighted average fair value of stock options granted in the first six months of 2020 was $106.26 per share.

Stock option transactions for the second quarter and first six months of 2020 are summarized as follows:

	2020
	Second Quarter			Six Months
	Shares	Weighted Average Exercise Price		Shares	Weighted Average Exercise Price
Beginning balance	2,135,096	$	160.32	1,988,576	$	130.66

Performance Share Plan and Restricted Stock Award Program

Under the 2015 to 2017 Performance Share Plan, the Company issued 7,673 shares of Teledyne common stock in the first quarter of 2020, 8,586 shares in the first quarter of 2019 and 6,481 shares in the first quarter of 2018.

In the first quarter of 2018, the performance cycle for the three-year period ending December 31, 2020, was set.  Subject to the terms of the plan, the maximum number of shares that could be issued in three equal installments in 2021, 2022 and 2023 is 61,194.

The following table shows the restricted stock activity for the first six months of 2020:

	Shares	Weighted average fair value per share
Balance, December 29, 2019	56,412	$	158.62
Granted	10,080	$	360.33
Vested	(23,087)	$	114.74
Balance, June 28, 2020	43,405	$	228.80

Note 7. Inventories

Inventories are stated at current cost, net of reserves for excess, slow moving and obsolete inventory. Inventories are valued under the FIFO method, LIFO method or average cost method. Inventories at cost determined on the average cost or the FIFO methods were $363.4 million at June 28, 2020 and $361.2 million at December 29, 2019. The remainder of the inventories using the LIFO method is $36.3 million at June 28, 2020 and $40.0 million at December 29, 2019. Interim LIFO calculations are based on the Company’s estimates of expected year-end inventory levels and costs since an actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Because these estimates are subject to many factors beyond the Company’s control, interim results are subject to the final year-end LIFO inventory valuation.

Total inventories, net	$	392.3	$	393.4

Note 8. 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 six months of 2020 was approximately $10.2 million of favorable operating income, primarily related to favorable changes in estimates that impacted revenue within the Digital Imaging operating segment. The net aggregate effects of changes in estimates on contracts accounted for under the cost-to-cost method in the first six months of 2019 was approximately $12.6 million of favorable operating income, primarily 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 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 $123.2 million and $15.2 million as of June 28, 2020, and $126.8 million and $17.9 million as of December 29, 2019, respectively.

The Company recognized revenue of $51.9 million during the six months ended June 28, 2020 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 June 28, 2020, the aggregate amount of the transaction price allocated to remaining performance obligations was $1,806.2 million. The Company expects approximately 74% of remaining performance obligations to be recognized into revenue within the next twelve months, with the remaining 26% 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.

	Six Months
Warranty Reserve (in millions):	2020		2019
Balance at beginning of year	$	24.8	$	21.0
Accruals for product warranties charged to expense and other	0.7		5.1
Cost of product warranty claims	(5.3)		(4.6)
Acquisition	0.1		0.3
Balance at end of period	$	20.3	$	21.8

Accounts Receivable, Net

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, which are included in accrued liabilities and other long-term liabilities) on the Condensed Consolidated Balance Sheet. Under the typical payment terms of our over time contracts, the customer pays us either performance-based payments or progress payments. Amounts billed and due from our customers are classified as receivables on the Condensed Consolidated Balance Sheet. Accounts receivable is presented net of an allowance for doubtful accounts of $12.0 million at June 28, 2020, and $10.2 million at December 29, 2019.

An allowance for doubtful accounts is established for losses expected to be incurred on accounts receivable balances. Judgment is required in the estimation of the allowance and we evaluate the collectability of our accounts receivable and contract assets based on a combination of factors. If we become 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, we use an aging schedule and recognize allowances for doubtful accounts based on the creditworthiness of the debtor, the age and status of outstanding receivables, the current business environment and our historical collection experience adjusted for current expectations for the customers or industry. Accounts receivable are written off against the allowance for uncollectible accounts when we determine amounts are no longer collectible.

	Six Months
Allowance for doubtful accounts (in millions):	2020
Balance at beginning of period	$	10.2
Accruals for credit loss charged to expense	2.8
Other deductions	(1.0)
Balance at end of period	$	12.0

Note 9. 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 second quarter and first six months of 2020 was 13.2% and 15.8%, respectively. The Company's effective income tax rate for the second quarter and first six months of 2019 was 18.2% and 18.5%, respectively. The second quarter and first six months of 2020 include net discrete income tax benefits of $10.4 million and $14.6 million, respectively. The second quarter and first six months of 2020 net discrete income tax benefits include $9.8 million and $14.5 million, respectively, related to share-based accounting. The second quarter and first six months of 2019 include net discrete income tax benefits of $4.3 million and $7.4 million, respectively. The 2019 second quarter and first six months net discrete tax benefits includes $4.8 million and $7.7 million, respectively, related to share-based accounting. Excluding the net discrete income tax benefits in both periods, the effective tax rates would have been 22.8% for both the second quarter and first six months of 2020. Excluding the net discrete income tax benefits in both periods, the effective tax rates would have been 21.6% for the second quarter of 2019 and 21.9% for the first six months of 2019.

Available borrowing capacity under the $750.0 million credit facility, which is reduced by borrowings and certain outstanding letters of credit, was $614.5 million at June 28, 2020. The credit agreements require the Company to comply with various financial and operating covenants and at June 28, 2020, the Company was in compliance with these covenants. At June 28, 2020, Teledyne had $25.8 million in outstanding letters of credit.

Teledyne estimates the fair value of its long-term debt based on debt of similar type, rating and maturity and at comparable interest rates. The Company’s long-term debt is considered a level 2 fair value hierarchy and is valued based on observable market data. The estimated fair value of Teledyne’s long-term debt at June 28, 2020 and December 29, 2019, approximated the carrying value.

Note 11. Lease Commitments

At June 28, 2020, Teledyne has right-of-use assets of $120.4 million and a total lease liability for operating leases of $131.1 million of which $111.7 million is included in long-term lease liabilities and $19.4 million is included in current accrued liabilities. Operating lease expense was $6.0 million and $12.1 million for the second quarter and first six months of 2020, respectively. Operating lease expense was $5.8 million and $11.6 million for the second quarter and first six months of 2019, respectively.

Note 12. 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 December 29, 2019, included in the 2019 Form 10-K.

At June 28, 2020, the Company’s reserves for environmental remediation obligations totaled $6.6 million, of which $1.5 million is included in current accrued liabilities. At December 29, 2019, the Company’s reserves for environmental remediation obligations totaled $6.0 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.

We are currently monitoring an exposure of approximately $40.0 million related to certain receivables, inventories and additional AOS-related expenses as a result of the March 27, 2020 bankruptcy of OneWeb Global Limited and its subsidiaries (“OneWeb”). Teledyne’s customer, Airbus OneWeb Satellites, LLC (“AOS”), a joint venture of OneWeb and Airbus Defense and Space, has not declared bankruptcy. Although it is reasonably possible that we may recognize a loss, given the uncertainty of the situation at this time, a loss, if any, will depend on the outcome of future events that could impact AOS.

A number of other lawsuits, claims and proceedings have been or may be asserted against the Company, including those pertaining to product liability, acquisitions, patent infringement, contracts, environmental, employment and employee benefits matters. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to the Company, management does not believe that the disposition of any such pending matters is likely to have a material adverse effect on the Company’s financial statements.

Note 13. Pension Plans and Postretirement Benefits

Effective January 1, 2020, Teledyne restructured its domestic qualified defined benefit pension plan. The restructuring involved dividing our domestic qualified defined pension plan into two separate plans, one comprised primarily of inactive participants (the “inactive plan”) and the other comprised primarily of active participants (the “active plan”). The reorganization was made to efficiently facilitate a targeted investment strategy and to provide additional flexibility in evaluating opportunities to reduce risk and volatility. As a result of the restructuring, the Company re-measured the assets and liabilities of the two plans, based on assumptions and market conditions on the January 1, 2020 effective date. Actuarial gains and losses associated with the active plan will continue to be amortized over the average remaining service period of the active participants, while the actuarial gains and losses associated with the inactive plan will be amortized over the average remaining life expectancy of the inactive participants which is currently approximately 17.7 years.

For the domestic qualified pension plans, the weighted-average discount rate decreased to 3.41% in 2020 compared with a 4.59% discount rate used in 2019. Teledyne has not made any cash pension contributions to its domestic qualified pension plan since 2013. No cash pension contributions are planned for 2020 for the domestic qualified pension plans.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Teledyne Technologies Incorporated provides enabling technologies for industrial growth markets that require advanced technology and high reliability. These markets include aerospace and defense, factory automation, air and water quality environmental monitoring, electronics design and development, oceanographic research, deepwater oil and gas exploration and production, medical imaging and pharmaceutical research. Our products include digital imaging sensors, cameras and systems within the visible, infrared and X-ray spectra, monitoring and control instrumentation for marine and environmental applications, harsh environment interconnects, electronic test and measurement equipment, aircraft information management systems, and defense electronics and satellite communication subsystems. We also supply engineered systems for defense, space, environmental and energy applications. We differentiate ourselves from many of our direct competitors by having a customer and company-sponsored applied research center that augments our product development expertise.

Strategy/Overview

Our strategy continues to emphasize growth in our core markets of instrumentation, digital imaging, aerospace and defense electronics and engineered systems. Our core markets are characterized by high barriers to entry and include specialized products and services not likely to be commoditized. We intend to strengthen and expand our core businesses with targeted acquisitions and through product development. We continue to focus on balanced and disciplined capital deployment among capital expenditures, product development, acquisitions and share repurchases. We aggressively pursue operational excellence to continually improve our margins and earnings by emphasizing cost containment and cost reductions in all aspects of our business. At Teledyne, operational excellence includes the rapid integration of the businesses we acquire. Using complementary technology across our businesses and internal research and development, we seek to create new products to grow our company and expand our addressable markets. We continue to evaluate our businesses to ensure that they are aligned with our strategy.

COVID-19 and other matters

With regard to the COVID-19 pandemic, our first priority remains the health and safety of our employees and their families. Up to 30% of our total personnel are working from home. Our manufacturing sites remain operational, and we are practicing social distancing, enhanced cleaning protocols, usage of personal protective equipment and other preventative measures.

While no company is immune to global economic challenges, Teledyne's business portfolio is well-balanced across end markets and geographies, and includes a high degree of businesses serving critical infrastructure sectors such as the defense industrial base, water and wastewater, and healthcare and public health. Teledyne’s balance sheet is strong, with $382.8 million of cash and cash equivalents and $614.5 million available under our credit facility maturing in 2024. However, given the continuing dynamic nature of this situation, the Company may not fully estimate the impacts of COVID-19 on its financial condition, results of operations or cash flows.

We are currently monitoring an exposure of approximately $40.0 million related to certain receivables, inventories and additional AOS-related expenses as a result of the March 27, 2020 bankruptcy of OneWeb Global Limited and its subsidiaries (“OneWeb”). Teledyne’s customer, Airbus OneWeb Satellites, LLC (“AOS”), a joint venture of OneWeb and Airbus Defense and Space, has not declared bankruptcy. Although it is reasonably possible that we may recognize a loss, given the uncertainty of the situation at this time, a loss, if any, will depend on the outcome of future events that could impact AOS.

Net income per diluted share was $2.48 for the second quarter of 2020, compared with net income per diluted share of $2.80. The second quarter of 2020 included $8.6 million in severance, facility consolidation and acquisition costs compared with $1.3 million in severance, facility consolidation and acquisition costs for the second quarter of 2019. The second quarter of 2020 included net discrete income tax benefits of $10.4 million compared with $4.3 million for the second quarter of 2019.

Net Sales

The second quarter of 2020 net sales, compared with the second quarter of 2019 net sales, reflected lower net sales in each segment except the Engineered Systems segment. The second quarter of 2020 sales included $29.5 million in incremental net sales from recent acquisitions.

Cost of Sales

Cost of sales decreased $3.0 million in the second quarter of 2020 and reflected the impact of lower sales, partially offset by higher severance and facility costs. Cost of sales as a percentage of net sales increased for the second quarter of 2020 to 62.0%, from 59.3% and reflected the impact of higher severance and facility consolidation costs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses, including research and development expense, decreased $13.6 million in the second quarter of 2020 and primarily reflected the impact of lower sales. Selling, general and administrative expenses for the second quarter of 2020, as a percentage of net sales decreased to 23.2% from 23.8% and reflected the impact of lower corporate expense. Corporate expense, which is included in selling, general and administrative expenses, was $13.8 million for the second quarter of 2020, compared with $16.3 million and reflected lower consulting and travel expense. In the second quarter of 2020 and 2019, we recorded a total of $5.7 million and $5.8 million, respectively, in stock option compensation expense.

22

Pension service expense is included in both cost of sales and selling general and administrative expense. For the second quarter of 2020 pension service expense was $2.6 million compared with $2.3 million. For 2020, the weighted-average discount rate used to determine the benefit obligation for the domestic qualified pension plans was 3.41% compared with 4.59% in 2019.

Operating Income

Operating income for the second quarter of 2020 decreased 16.8%. The second quarter of 2020, compared with the second quarter of 2019, reflected lower operating income in each segment except the Engineered Systems segment. The second quarter of 2020 included $8.6 million in severance, facility consolidation and acquisition costs, compared with $1.3 million in severance, facility consolidation and acquisition costs for the second quarter of 2019. The incremental operating income included in the results for the second quarter of 2020 from recent acquisitions was $1.9 million.

Interest Expense, Non-Service Retirement Benefit Income and Other Income/Expense

Interest expense, net of interest income, was $3.7 million for the second quarter of 2020, compared with $5.4 million, and reflected the impact of lower average interest rates. Non-service retirement benefit income was $3.2 million for the second quarter of 2020, compared with $2.0 million. Other income and expense was expense of $1.4 million for the second quarter of 2020, compared with expense of $0.6 million.

Income Taxes

The income tax provision is calculated using an estimated annual effective tax rate, based upon estimates of annual income, permanent items, statutory tax rates and planned tax strategies in the various jurisdictions in which we operate except that certain loss jurisdictions and discrete items, such as the resolution of uncertain tax positions and share-based accounting income tax benefits, are treated separately.

The Company’s effective income tax rate for the second quarter of 2020 was 13.2%, compared with 18.2%. The second quarter of 2020 reflected net discrete income tax benefits of $10.4 million, which included a $9.8 million income tax benefit related to share-based accounting. The second quarter of 2019 included net discrete tax benefits of $4.3 million, which included a $4.8 million income tax benefit related to share-based accounting. Excluding the net discrete income tax benefits in both periods, the effective tax rates would have been 22.8% for the second quarter of 2020 and 21.6% for the second quarter of 2019. The Company’s annual effective tax rate for fiscal year 2020 is expected to be 22.8% before discrete tax items. In addition, we currently expect significantly less discrete tax items in 2020 compared with 2019.

First six months of 2020 compared with the first six months of 2019

Our first six months of 2020 net sales increased slightly. Net income for the first six months of 2020 decreased 2.2%. Net income per diluted share was $4.65 for the first six months of 2020 compared with net income per diluted share of $4.82. The first six months of 2020 included net discrete income tax benefits of $14.6 million compared with $7.4 million. The first six months of 2020 included $19.0 million in severance, facility consolidation, acquisition and certain changes in contract cost estimates, compared with $3.7 million in severance and facility consolidation costs for the first six months of 2019.

Net Sales

The first six months of 2020 net sales, compared with the first six months of 2019 net sales, reflected higher net sales in each segment except the Aerospace and Defense segment. The first six months of 2020 included $60.2 million in incremental net sales from recent acquisitions.

Cost of Sales

Cost of sales increased $25.7 million in the first six months of 2020 and primarily reflected the impact of severance, facility consolidation, acquisition and certain changes in contract cost estimates. Cost of sales as a percentage of net sales for the six months of 2020 increased to 62.4%, compared with 60.7% and reflected the impact of severance, facility consolidation, acquisition and certain changes in contract cost estimates.

Selling, General and Administrative Expenses

Selling, general and administrative expenses, including research and development, decreased by $9.6 million in the first six months of 2020 and reflected lower research and development expense and lower corporate expense. Selling, general and administrative expenses for the first six months of 2020, as a percentage of net sales, decreased slightly to 23.6% compared with 24.3%.

Financial Condition, Liquidity and Capital Resources

Our net cash provided by operating activities was $232.2 million for the first six months of 2020, compared with net cash provided by operating activities of $163.3 million. The higher cash provided by operating activities in the first six months of 2020 reflected improved accounts receivable collections and $33.4 million of deferred tax payments, as well as, cash flow from recent acquisitions.

Our net cash used by investing activities was $65.7 million for the first six months of 2020, compared with net cash used by investing activities of $261.6 million. The 2020 and 2019 first six months included $29.0 million and $222.5 million, respectively, for recent acquisitions. On January 5, 2020, we acquired OakGate for $28.5 million in cash. In February 2019, we acquired the scientific imaging businesses of Roper Technologies, Inc. for $224.8 million in cash. Capital expenditures for the first six months of 2020 and 2019 were $36.8 million and $39.4 million, respectively. Our goodwill was $2,061.3 million at June 28, 2020 and $2,050.5 million at December 29, 2019. Goodwill resulting from the acquisition of OakGate will not be deductible for tax purposes. Teledyne’s net acquired intangible assets were $409.2 million at June 28, 2020 and $430.8 million at December 29, 2019. The decrease in the balance of net acquired intangible assets primarily reflected amortization of acquired intangible assets. The Company is in the process of specifically identifying the amount to be assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the OakGate acquisition and the gas and flame detection business and the Micralyne acquisitions since there was insufficient time between the acquisition dates and the end of the period to finalize the analysis.

27

Financing activities provided cash of $27.8 million for the first six months of 2020, compared with cash provided by financing activities of $64.6 million. Proceeds from the exercise of stock options were $28.2 million for the first six months of 2020 compared with $20.7 million for the first six months of 2019.

Total debt at June 28, 2020 was $851.4 million. At June 28, 2020, $125.0 million was outstanding under the $750.0 million credit facility. At June 28, 2020, Teledyne had $25.8 million in outstanding letters of credit. Available borrowing capacity under the $750.0 million credit facility, which is reduced by borrowings and certain outstanding letters of credit, was $614.5 million at June 28, 2020. The credit agreements require the Company to comply with various financial and operating covenants and at June 28, 2020, the Company was in compliance with these covenants.

Our principal cash and capital requirements are to fund working capital needs, capital expenditures, income tax payments, pension contributions, debt service requirements and the stock repurchase program, as well as acquisitions. It is anticipated that operating cash flow, together with available borrowings under the credit facility described below, will be sufficient to meet these requirements over the next twelve months. We may raise debt capital, depending on financial, market and economic conditions. We may need to raise additional capital to support acquisitions. We currently expect to spend approximately $70.0 million for capital expenditures in 2020, of which $36.8 million has been spent in the first six months of 2020. No cash pension contributions have been made since 2013 or are planned for the remainder of 2020 for the domestic qualified pension plan.

As of June 28, 2020, the Company had an adequate amount of margin between required financial covenant ratios (as required by applicable credit agreements) and our actual ratios. At June 28, 2020, the required financial ratios and the actual ratios were as follows:

$750.0 million Credit Facility expires March 2024 and $150.0 million term loan due October 2024 (issued October 2019)
Financial Covenants	Requirement	Actual Measure
Consolidated Leverage Ratio (Net Debt/EBITDA) (a)	No more than 3.25 to 1	1.46 to 1
Consolidated Interest Coverage Ratio (EBITDA/Interest) (b)	No less than 3.0 to 1	32.9 to 1
$575.5 million Private Placement Senior Notes due from September 2020 to 2024
Financial Covenants	Requirement	Actual Measure
Consolidated Leverage Ratio (Net Debt/EBITDA) (a)	No more than 3.25 to 1	1.46 to 1
Consolidated Interest Coverage Ratio (EBITDA/Interest) (b)	No less than 3.0 to 1	32.9 to 1

a) The Consolidated Leverage Ratio is equal to Net Debt/EBITDA as defined in our private placement note purchase agreement and our $750.0 million credit agreement.

b) The Consolidated Interest Coverage Ratio is equal to EBITDA/Interest as defined in our private placement note purchase agreement and our $750.0 million credit agreement.

Our liquidity is not dependent upon the use of off-balance sheet financial arrangements. We have no off-balance sheet financing arrangements that incorporate the use of special purpose entities or unconsolidated entities.

Critical Accounting Policies

Our critical accounting policies are those that are reflective of significant judgments and uncertainties, and may potentially result in materially different results under different assumptions and conditions. Our critical accounting policies are the following: revenue recognition; accounting for pension plans; accounting for business combinations, goodwill, acquired intangible assets and other long-lived assets; and accounting for income taxes.

For additional discussion of the application of the critical accounting policies and other accounting policies, see Note 1 to these condensed consolidated financial statements and also Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Note 2 of the Notes to Consolidated Financial Statements included in Teledyne’s 2019 Form 10-K.

Safe Harbor Cautionary Statement Regarding Forward-Looking Information

From time to time we make, and this report contains, forward looking statements, as defined in the Private Securities Litigation Reform Act of 1995, directly or indirectly relating to sales, earnings, operating margin, growth opportunities, acquisitions, product sales, capital expenditures, pension matters, stock option compensation expense, the credit facility, interest expense, severance, relocation and facility consolidation costs, environmental remediation costs, stock repurchases, taxes, exchange rate fluctuations and strategic plans. Forward-looking statements are generally accompanied by words such as “estimate”, “project”, “predict”, “believes” or “expect”, that convey the uncertainty of future events or outcomes. All statements made in this Management’s Discussion and Analysis of Financial Condition and Results of Operations and in other sections of this Form 10-Q that are not historical in nature should be considered forward-looking.

Actual results could differ materially from these forward-looking statements. Many factors could change the anticipated results, including: disruptions in the global economy caused by the spread of the COVID-19 pandemic resulting in production, supply, contractual and other disruptions, including facility closures and furloughs and travel restrictions; customer and supplier bankruptcies; changes in demand for products sold to the defense electronics, instrumentation, digital imaging, energy exploration and production, commercial aviation, semiconductor and communications markets; funding, continuation and award of government programs; cuts to defense spending resulting from existing and future deficit reduction measures or changes to U.S. and foreign government spending and budget priorities triggered by the COVID-19 pandemic; the outcome of the OneWeb bankruptcy; impacts from the United Kingdom’s exit from the European Union; uncertainties related to the policies of the U.S. Presidential Administration and uncertainties related to the 2020 Presidential and Congressional elections; the imposition and expansion of, and responses to, trade sanctions and tariffs; escalating economic and diplomatic tension between China and the United States; and threats to the security of our confidential and proprietary information, including cyber security threats. Lower oil and natural gas prices, as well as instability in the Middle East or other oil producing regions, and new regulations or restrictions relating to energy production, could further negatively affect our businesses that supply the oil and gas industry. Disruptions from the production delay of Boeing’s 737 Max aircraft and continued weakness in the commercial aerospace industry due to the COVID-19 pandemic will negatively affect our aerospace electronics businesses. In addition, financial market fluctuations affect the value of the company's pension assets.

Changes in the policies of U.S. and foreign governments, including economic sanctions, could result, over time, in reductions or realignment in defense or other government spending and further changes in programs in which the company participates.

While the company’s growth strategy includes possible acquisitions, we cannot provide any assurance as to when, if or on what terms any acquisitions will be made. Acquisitions involve various inherent risks, such as, among others, our ability to integrate acquired businesses, retain customers and achieve identified financial and operating synergies. There are additional risks associated with acquiring, owning and operating businesses internationally, including those arising from U.S. and foreign government policy changes or actions and exchange rate fluctuations.

While we believe our internal and disclosure control systems are effective, there are inherent limitations in all control systems, and misstatements due to error or fraud may occur and not be detected.

Readers are urged to read our periodic reports filed with the Securities and Exchange Commission for a more complete description of our Company, its businesses, its strategies and the various risks that we face. Various risks are identified in Teledyne’s 2019 Form 10-K and subsequent Quarterly Reports on Form 10-Q.

We assume no duty to publicly update or revise any forward-looking statements, whether as a result of new information or otherwise.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

Except as set forth below, there were no material changes to the information provided under “Item 7A, Quantitative and Qualitative Disclosure About Market Risk” included in our 2019 Form 10-K.

Market Risk

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 objective is to protect the United States 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 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 U.S. dollar denominated, variable rate and fixed rate debt obligations of a European subsidiary, 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.

29

Foreign Currency Exchange Rate Risk

Notwithstanding our efforts to mitigate portions of our foreign currency exchange rate risks, there can be no assurance that our hedging activities will adequately protect us against the risks associated with foreign currency fluctuations. A hypothetical 10 percent price change in the U.S. dollar from its value at June 28, 2020 would result in a decrease or increase in the fair value of our foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars by approximately $9.3 million. A hypothetical 10 percent price change in the U.S. dollar from its value at June 28, 2020 would result in a decrease or increase in the fair value of our foreign currency forward contracts designated as cash flow hedges to buy British Pounds and to sell U.S. dollars by approximately $0.6 million. For additional information, see Derivative Instruments discussed in Note 4 to these condensed consolidated financial statements.

Market Risk Disclosure

We are exposed to market risk through the interest rate on our borrowings under our $750.0 million credit facility and our $150.0 million term loan. As of June 28, 2020, we had $125.0 million in outstanding under our credit facility and $150.0 million outstanding under our term loan for a total $275.0 million. A 100 basis point increase in interest rates would result in an increase in annual interest expense of approximately $2.75 million, assuming the $275.0 million in debt was outstanding for the full year. A hypothetical 10 percent price change in the U.S. dollar from its value at June 28, 2020 would result in a decrease or increase in the fair value of our Euro/U.S. Dollar cross currency swap designated as a cash flow hedge by approximately $28.9 million. A hypothetical 10 percent increase in the U.S. interest rates at March 29, 2020 would result in an increase in the fair value of our U.S. dollar interest rate swap designated as a cash flow hedge by approximately $3.0 million.

Item 4. Controls and Procedures

Our disclosure controls and procedures are designed to ensure that information required to be disclosed in reports that we file or submit under the Securities Exchange Act of 1934, are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and to provide reasonable assurance that information required to be disclosed by us in such reports is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Our Chief Executive Officer and our Senior Vice President and Chief Financial Officer, with the participation and assistance of other members of management, have reviewed the effectiveness of our disclosure controls and procedures and have concluded that the disclosure controls and procedures, as of June 28, 2020, are effective at the reasonable assurance level.

In connection with our evaluation during the quarterly period ended June 28, 2020, we have made no changes in our internal controls over financial reporting that have materially affected or are reasonably likely to materially affect our internal controls over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

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 accounting principles generally accepted 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 December 29, 2019 (“2019 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 June 28, 2020 and the consolidated results of operations, consolidated comprehensive income for the second quarter and six months then ended and the consolidated cash flows for the six months then ended. The results of operations and cash flows for the periods ended June 28, 2020 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 related to the segment realignment in the third quarter of 2019.

Cash Equivalents

Cash equivalents consist of highly liquid money-market mutual funds and bank deposits with maturities of three months or less when purchased. Cash equivalents totaled $203.0 million at June 28, 2020. There were no cash equivalents at December 29, 2019.

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the computation of the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record a goodwill impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. We adopted the new guidance as of December 30, 2019 which reduced the complexity surrounding the evaluation of goodwill for impairment. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The standard replaces the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires the use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. The standard requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We adopted the new guidance as of December 30, 2019 using the modified retrospective approach related to our accounts receivables and contract assets, resulting in no cumulative adjustment to retained earnings. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.

Goodwill and Acquired Intangible Assets

Teledyne’s goodwill was $2,061.3 million at June 28, 2020 and $2,050.5 million at December 29, 2019. The increase in the balance of goodwill in 2020 resulted from goodwill from recent acquisitions, mostly offset by exchange rate changes. Goodwill resulting from the acquisition of OakGate will not be deductible for tax purposes. Teledyne’s net acquired intangible assets were $409.2 million at June 28, 2020 and $430.8 million at December 29, 2019. The decrease in the balance of net acquired intangible assets resulted from amortization of acquired intangible assets and exchange rate changes. The Company completed the process of specifically identifying the amount to be assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the scientific imaging businesses acquisition. The Company is in the process of specifically identifying the amount to be assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the OakGate acquisition and the gas and flame detection business and the Micralyne acquisitions since there was insufficient time between the acquisition dates and the end of the period to finalize the analysis.

During the second quarter of 2020, the Company evaluated the effects of the COVID-19 pandemic and its negative impact on the global economy on each of the Company’s reporting units and indefinite-lived intangible assets. Management reviewed key assumptions, including revisions of projected future revenues for reporting units and the results of the previous annual impairment testing performed during the fourth quarter of 2019. The Company did not identify an indication of impairment for each of its reporting units and indefinite-lived intangible assets. Although it was determined that a triggering event had not occurred as of June 28, 2020, we will continue to monitor the impacts of the COVID-19 pandemic on the Company’s reporting units and indefinite-lived intangible assets.

Teledyne funded the acquisitions with borrowings under its credit facility and cash on hand. The results of each acquisition have been included in Teledyne’s results since the date of each respective acquisition.

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 a U.S. dollar denominated, variable rate obligation into a euro fixed rate obligation using a receive float, 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.

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 consolidated statements of income, at which time the effective amount in AOCI is

reclassified to revenue in our 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 $0.9 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 $2.0 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 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.

As of June 28, 2020, Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $93.1 million. These foreign currency forward contracts have maturities ranging from September 2020 to May 2021. Teledyne had foreign currency forward contracts designated as cash flow hedges to buy British pounds and to sell U.S. dollars totaling $6.5 million. These foreign currency forward contracts have maturities ranging from September 2020 to February 2021. The cross currency swaps have notional amounts of €113.0 million and $125 million, and €135.0 million and $150.0 million, and matures in March 2023 and October 2024, respectively. The interest rate swap has a notional amount of $125.0 million and matures in March 2023.

The effect of derivative instruments designated as cash flow hedges in the condensed consolidated financial statements for the second quarter and six months ended June 28, 2020 and June 30, 2019 was as follows (in millions):

	Second Quarter				Six Months

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 June 28, 2020, Teledyne had non-designated foreign currency contracts, (in excess of approximately $311.2 million) of this type in the following pairs (in millions):

Contracts to Buy			Contracts to Sell
Currency	Amount		Currency	Amount
Canadian Dollars	$	51.0	U.S. Dollars	US$	37.6
Canadian Dollars	$	15.1	Euros	€	9.9
Great Britain Pounds	£	61.8	U.S. Dollars	US$	76.9
Euros	€	31.0	U.S. Dollars	US$	34.8
Danish Krone	DKR	139.4	U.S. Dollars	US$	21.0
Great Britain Pounds	£	5.9	Euros	€	6.6

The above 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 second quarter and six months ended June 28, 2020 was income of $1.8 million and expense of $8.6 million, respectively.. The effect of derivative instruments not designated as cash flow hedges in other income and expense for the second quarter and six months

ended June 30, 2019 was expense of $0.7 million and income of $0.9 million, respectively. The income/expense was largely offset by losses/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 (specifically futures contracts on LIBOR and EURIBOR) and inputs other than quoted prices that are observable for the asset or liability (specifically LIBOR 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):

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation Plans

Stock-Based Compensation Plans

Teledyne has long-term incentive plans pursuant to which it has granted non-qualified stock options, restricted stock and performance shares to certain employees. The Company also has non-employee Board of Director stock compensation plans, pursuant to which common stock, stock options and restricted stock units have been issued to its directors.

Stock Incentive Plan

Stock option compensation expense was $5.7 million for the second quarter of 2020 and was $5.8 million for the second quarter of 2019. Stock option compensation expense was $13.1 million for the first six months of 2020 and was $14.7 million for the first six months of 2019. Employee stock option grants are charged to expense evenly over the three year vesting period except for stock options that were granted after 2018 to Teledyne’s Executive Chairman and Teledyne’s President and Chief Executive Officer which were expensed immediately. For 2020, the Company currently expects approximately $25.2 million in stock option compensation expense based on stock options outstanding at June 28, 2020. This amount can be impacted by employee retirements and terminations or stock options granted during the remainder of the year. The Company issues shares of common stock upon the exercise of stock options.

The following assumptions were used in the valuation of stock options granted in the first six months of 2020:

	2020
Expected volatility	23.7%
Risk-free interest rate range	1.50% to 1.75%
Expected life in years	6.6
Expected dividend yield	—

Based on the assumptions used in the valuation of stock options, the grant date weighted average fair value of stock options granted in the first six months of 2020 was $106.26 per share.

Stock option transactions for the second quarter and first six months of 2020 are summarized as follows:

	2020

Inventories

Inventories

Inventories are stated at current cost, net of reserves for excess, slow moving and obsolete inventory. Inventories are valued under the FIFO method, LIFO method or average cost method. Inventories at cost determined on the average cost or the FIFO methods were $363.4 million at June 28, 2020 and $361.2 million at December 29, 2019. The remainder of the inventories using the LIFO method is $36.3 million at June 28, 2020 and $40.0 million at December 29, 2019. Interim LIFO calculations are based on the Company’s estimates of expected year-end inventory levels and costs since an actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Because these estimates are subject to many factors beyond the Company’s control, interim results are subject to the final year-end LIFO inventory valuation.

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 six months of 2020 was approximately $10.2 million of favorable operating income, primarily related to favorable changes in estimates that impacted revenue within the Digital Imaging operating segment. The net aggregate effects of changes in estimates on contracts accounted for under the cost-to-cost method in the first six months of 2019 was approximately $12.6 million of favorable operating income, primarily 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 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 $123.2 million and $15.2 million as of June 28, 2020, and $126.8 million and $17.9 million as of December 29, 2019, respectively.

The Company recognized revenue of $51.9 million during the six months ended June 28, 2020 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 June 28, 2020, the aggregate amount of the transaction price allocated to remaining performance obligations was $1,806.2 million. The Company expects approximately 74% of remaining performance obligations to be recognized into revenue within the next twelve months, with the remaining 26% 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.

Accounts Receivable, Net

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, which are included in accrued liabilities and other long-term liabilities) on the Condensed Consolidated Balance Sheet. Under the typical payment terms of our over time contracts, the customer pays us either performance-based payments or progress payments. Amounts billed and due from our customers are classified as receivables on the Condensed Consolidated Balance Sheet. Accounts receivable is presented net of an allowance for doubtful accounts of $12.0 million at June 28, 2020, and $10.2 million at December 29, 2019.

An allowance for doubtful accounts is established for losses expected to be incurred on accounts receivable balances. Judgment is required in the estimation of the allowance and we evaluate the collectability of our accounts receivable and contract assets based on a combination of factors. If we become 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, we use an aging schedule and recognize allowances for doubtful accounts based on the creditworthiness of the debtor, the age and status of outstanding receivables, the current business environment and our historical collection experience adjusted for current expectations for the customers or industry. Accounts receivable are written off against the allowance for uncollectible accounts when we determine amounts are no longer collectible.

Income Taxes	Income TaxesThe 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 second quarter and first six months of 2020 was 13.2% and 15.8%, respectively. The Company's effective income tax rate for the second quarter and first six months of 2019 was 18.2% and 18.5%, respectively. The second quarter and first six months of 2020 include net discrete income tax benefits of $10.4 million and $14.6 million, respectively. The second quarter and first six months of 2020 net discrete income tax benefits include $9.8 million and $14.5 million, respectively, related to share-based accounting. The second quarter and first six months of 2019 include net discrete income tax benefits of $4.3 million and $7.4 million, respectively. The 2019 second quarter and first six months net discrete tax benefits includes $4.8 million and $7.7 million, respectively, related to share-based accounting. Excluding the net discrete income tax benefits in both periods, the effective tax rates would have been 22.8% for both the second quarter and first six months of 2020. Excluding the net discrete income tax benefits in both periods, the effective tax rates would have been 21.6% for the second quarter of 2019 and 21.9% for the first six months of 2019.

Available borrowing capacity under the $750.0 million credit facility, which is reduced by borrowings and certain outstanding letters of credit, was $614.5 million at June 28, 2020. The credit agreements require the Company to comply with various financial and operating covenants and at June 28, 2020, the Company was in compliance with these covenants. At June 28, 2020, Teledyne had $25.8 million in outstanding letters of credit.

Teledyne estimates the fair value of its long-term debt based on debt of similar type, rating and maturity and at comparable interest rates. The Company’s long-term debt is considered a level 2 fair value hierarchy and is valued based on observable market data. The estimated fair value of Teledyne’s long-term debt at June 28, 2020 and December 29, 2019, approximated the carrying value.

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 December 29, 2019, included in the 2019 Form 10-K.

At June 28, 2020, the Company’s reserves for environmental remediation obligations totaled $6.6 million, of which $1.5 million is included in current accrued liabilities. At December 29, 2019, the Company’s reserves for environmental remediation obligations totaled $6.0 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.

We are currently monitoring an exposure of approximately $40.0 million related to certain receivables, inventories and additional AOS-related expenses as a result of the March 27, 2020 bankruptcy of OneWeb Global Limited and its subsidiaries (“OneWeb”). Teledyne’s customer, Airbus OneWeb Satellites, LLC (“AOS”), a joint venture of OneWeb and Airbus Defense and Space, has not declared bankruptcy. Although it is reasonably possible that we may recognize a loss, given the uncertainty of the situation at this time, a loss, if any, will depend on the outcome of future events that could impact AOS.

A number of other lawsuits, claims and proceedings have been or may be asserted against the Company, including those pertaining to product liability, acquisitions, patent infringement, contracts, environmental, employment and employee benefits matters. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to the Company, management does not believe that the disposition of any such pending matters is likely to have a material adverse effect on the Company’s financial statements.

Retirement Benefits [Abstract]

Pension Plans and Postretirement Benefits

Pension Plans and Postretirement Benefits

Effective January 1, 2020, Teledyne restructured its domestic qualified defined benefit pension plan. The restructuring involved dividing our domestic qualified defined pension plan into two separate plans, one comprised primarily of inactive participants (the “inactive plan”) and the other comprised primarily of active participants (the “active plan”). The reorganization was made to efficiently facilitate a targeted investment strategy and to provide additional flexibility in evaluating opportunities to reduce risk and volatility. As a result of the restructuring, the Company re-measured the assets and liabilities of the two plans, based on assumptions and market conditions on the January 1, 2020 effective date. Actuarial gains and losses associated with the active plan will continue to be amortized over the average remaining service period of the active participants, while the actuarial gains and losses associated with the inactive plan will be amortized over the average remaining life expectancy of the inactive participants which is currently approximately 17.7 years.

For the domestic qualified pension plans, the weighted-average discount rate decreased to 3.41% in 2020 compared with a 4.59% discount rate used in 2019. Teledyne has not made any cash pension contributions to its domestic qualified pension plan since 2013. No cash pension contributions are planned for 2020 for the domestic qualified pension plans.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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 accounting principles generally accepted 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 December 29, 2019 (“2019 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 June 28, 2020 and the consolidated results of operations, consolidated comprehensive income for the second quarter and six months then ended and the consolidated cash flows for the six months then ended. The results of operations and cash flows for the periods ended June 28, 2020 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 related to the segment realignment in the third quarter of 2019.

Cash Equivalents

Cash EquivalentsCash equivalents consist of highly liquid money-market mutual funds and bank deposits with maturities of three months or less when purchased.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the computation of the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record a goodwill impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. We adopted the new guidance as of December 30, 2019 which reduced the complexity surrounding the evaluation of goodwill for impairment. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The standard replaces the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires the use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. The standard requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We adopted the new guidance as of December 30, 2019 using the modified retrospective approach related to our accounts receivables and contract assets, resulting in no cumulative adjustment to retained earnings. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.
