NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
July 1, 2018March 31, 2019

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 31, 201730, 2018 (“20172018 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 July 1, 2018March 31, 2019 and the consolidated results of operations, consolidated comprehensive income or the three and six months then ended andconsolidated cash flows for the sixthree months then ended. The results of operations and cash flows for the periodthree months ended July 1, 2018March 31, 2019 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year. Certain prior year amounts have been reclassified to conform to the current period presentation.
In the second quarter of 2018, we realigned the reporting structure for certain of our microwave product groupings. These products, acquired with the acquisition of e2v technologies plc (“e2v”) were formerly reported as part of the Aerospace and Defense Electronics segment and are now reported as part of the Digital Imaging segment. Previously reported segment data has been adjusted to reflect this change. Total sales for these products were $24.2 million for fiscal year 2017.
Recent Accounting Pronouncements
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new guidance will require lessees to recognize most leases on their balance sheet as a right-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. The new guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The new guidance can be adopted using either a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented or a transition method whereby companies could continue to apply existing lease guidance during the comparative periods and apply the new lease requirements through a cumulative-effect adjustment in the period of adoption rather than in the earliest period presented without adjusting historical financial statements. We plan to adopt the new standard on December 31, 2018, the beginning of our 2019 fiscal year, and are currently evaluating the impact this guidance will have on the consolidated financial statements, including the selection of a transition method, and footnote disclosures. Please refer to Note 13 of the Notes to Consolidated Financial Statements included in our 2017 Form 10-K for additional information about the Company’s leases, including the future minimum lease payments of the Company’s operating leases at December 31, 2017.
In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”, to address a specific consequence of the Tax Cuts and Jobs Act (“Tax Act”) by allowing a reclassification from accumulated other comprehensive income (“AOCI”) to retained earnings for stranded tax effects resulting from the Tax Act reduction of the U.S. federal corporate income tax rate. The guidance is effective for all entities for annual periods beginning after December 15, 2018, with early adoption permitted,permitted. In 2018, we elected to early adopt this ASU and iselected to be applied eitherreclassify, in the period of adoption or retrospectivelyenactment, stranded tax effects totaling $47.6 million from AOCI to each periodretained earnings in which the effect of the change in the U.S. federal corporateour condensed consolidated balance sheet. The reclassification amount primarily included income tax rateeffects related to our pension and postretirement benefit plans. Income tax effects remaining in AOCI will be released into earnings as the Tax Act is recognized.   Teledyne is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.related pretax amounts are reclassified to earnings.
In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities.” This ASUnew guidance better aligns an entity’s risk management activities and financial reporting for hedging relationships. This ASUrelationships and expands and refines hedge accounting for both nonfinancial and financial risk components, and this ASUcomponents. This new guidance also simplifies and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This ASUnew guidance is effective for fiscal years beginning after December 15, 2018 and for interim periods therein, with early adoption permitted. Teledyne is currently evaluatingWe adopted the new guidance as of December 31, 2018 using the modified retrospective approach, there was no cumulative adjustment to retained earnings related to hedge ineffectiveness for the year ended December 31, 2018. Additionally, as a result of the adoption, we no longer disclose the ineffective portion of the change in fair value of our derivative financial instruments.  The entire change in the fair value of the cash flow hedging instruments aside from components excluded from the assessment of hedge effectiveness will now be recorded in other comprehensive income and subsequently reclassified to earnings in the period the hedged item impacts earnings.   The adoption of this standard did not have a material impact this guidance will have on theour condensed consolidated financial statements and footnote disclosures.

statements.
In January 2017, the FASB issued 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. The new standardguidance is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We expect the adoption of this standardguidance will reduce the complexity surrounding the evaluation of goodwill for impairment. The impact of this new standardguidance for the Company will depend on the outcomes of future goodwill impairment tests.
In May 2014,
In February 2016, the FASB issued ASU No. 2014-092016-02, Leases (Topic 606), Revenue from Contracts with Customers, which provides842). The new guidance requires lessees to recognize most leases on their balance sheet as a single comprehensiveright-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, for entitiesrequiring leases to use in accounting for revenue arising from contracts with customers and superseded most current revenue recognition guidance under Topic 605, Revenue Recognition. Underbe classified as either operating or finance. We adopted the new standard, an entity recognizes revenue when or as it satisfies a performance obligation by transferring controlguidance on December 31, 2018, the beginning of a good or service to the customer, either at a point in time or over time. The new standard requires expanded disclosures, including how and when we satisfy performance obligations as well as additional disaggregated revenue information to be provided more frequently in the reporting process.
In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This ASU requires the service cost component of net benefit costs to be disaggregated from all other components and be reported in the same line item or items as other compensation costs and allow only the service cost component to be eligible for capitalization when applicable. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and before income from operations. The Company adopted the requirements of this ASU as of January 1, 2018 on a retrospective basis. As such, the Company reclassified $2.9 million and $0.5 million from cost of sales and selling, general and administrative expenses, respectively to non-service retirement benefit income for the three months ended July 2, 2017 and reclassified $5.7 million and $1.0 million from cost of sales and selling, general and administrative expenses, respectively to non-service retirement benefit income for the six months ended July 2, 2017 to conform to current period presentation.
The Company adopted the requirements of Topic 606 as of January 1, 2018,our 2019 fiscal year using the modified retrospective transition methodmethod. Prior period comparative information was not adjusted. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which requiredamong other things, allowed us to carry forward the historical lease classification. The adoption of this guidance did not have a material impact related to existing leases and as a result, a cumulative-effect adjustment aswas not recorded. Also, the adoption of the datenew guidance did not have a material impact on our results of adoption. Adoption of Topic 606 primarily impacted contracts for which revenue prior to fiscal year 2018 was recognized using the percentage of completion (“POC”), units-of-deliveryoperations or milestone methods, as these contracts are now recognized primarily using the POC cost-to-cost method to depict the transfer of control of the good or service to the customer as the work on the contractcash flows.
Lease Commitments
We determine if an arrangement is performed. Also, to a much lesser extent, certain contracts for customized goods and services, certain products sold to the U.S. Government, and product repair contracts are now recognized over time, as control of the good or service produced transfers to the customer over time in accordance with the guidance in Topic 606. For impacted contracts that were in processlease at inception. Effective December 31, 2017, we calculated the difference2018, operating leases are recorded as right-of-use assets, other long-term lease liabilities and current accrued liabilities in the life to date revenue (and related costs and expenses) between legacy accounting standards and Topic 606, with the cumulative effect of initially applying Topic 606 as an adjustment to the opening balance of retained earnings, as shown below. The prior year comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. While Topic 606 includes additional disclosures, as discussed within these Notes to the Condensed Consolidated Financial Statements, comparative disclosures with prior periods are not required in the year of adoption due to our use of the modified retrospective transition method.
The cumulative effect of the changes made to our consolidated January 1, 2018 balance sheet for the adoption ofTopic 606 were as follows (in millions):

In accordance with the requirements of Topic 606, the disclosure of the impact of adoption on our condensed consolidated income statementbalance sheets. Finance leases are included in property and equipment, other current liabilities, and other long-term liabilities in our condensed consolidated balance sheetsheets.  
Operating lease right-of-use assets represent our right to use an underlying asset for the second quarterlease term and six months ended July 1, 2018 waslease liabilities represent our 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. Since most of our leases do not provide an implicit rate, we use our incremental borrowing rate to determine the present value of lease payments at the commencement date. We use the implicit rate when readily determinable. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Many lease agreements contain renewal options at either a fixed cost, fixed increase or market value adjustment. For those leases with renewal options, we will include the renewal options that are reasonably certain to be exercised, for purposes of calculating the lease liability and corresponding right of use asset. Teledyne will evaluate 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. 
Operating Leases
Teledyne has approximately 120 operating lease agreements, which are primarily for manufacturing facilities and office space. These agreements frequently include one or more renewal options and require the Company to pay for utilities, taxes, insurance and maintenance expense. No lease agreement imposes a restriction on the Company’s ability to engage in financing transactions or enter into further lease agreements. At March 31, 2019, Teledyne has right-of-use assets of $134.3 million and a total lease liability for operating leases of $144.0 million of which $126.0 million is included in long-term lease liabilities and $18.0 million is included in current accrued liabilities.
At March 31, 2019, future minimum lease payments for operating leases with non-cancelable terms of more than one year were as follows (in millions):

Significant Accounting Policies UpdateOther
Our significant accounting policiesfinance leases and subleases are detailed in “Note 2: Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the year ended December 31, 2017. Significant changes to our accounting policies as a result of adopting Topic 606 are discussed below.

Revenue Recognition
We determine the appropriate method by which we recognize 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. We account 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, we typically use the expected cost plus a margin approach to estimate the standalone selling price for that performance obligation. Approximately 60% of our revenue is recognized at a point in time, with the remaining 40% 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 Instrumentation, Digital Imaging, and Aerospace and Defense Electronics segments, and to a lesser extent for certain commercial contracts within the Engineered Systems segment relating to the sale of standard hydrogen/oxygen gas generators. In limited circumstances, customer specified acceptance criteria exist. If we cannot objectively demonstrate that the product meets those specifications prior to the shipment, the revenue is deferred until customer acceptance is obtained. Performance obligations recognized at a point in time 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 our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.
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 our 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 our 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. We generally use the cost-to-cost measure of progress as this measure best depicts the transfer of control to the customer which occurs as we incur costs on our 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, or other provisions that can either increase or decrease the transaction price. We estimate variable consideration at the amount to which we expect to be entitled, and we include 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 our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.
The majority of our 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. We consider contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of our contract modifications on 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 our 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 cost-to-cost, 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. This EAC process requires management’s judgment to make reasonably dependable cost estimates. 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 the first six months of 2018 was less than $0.1 million of unfavorable revenue and operating income. 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.
While extended or non-customary warranties do not represent a significant portion of our revenue, we recognize warranty services as a separate performance obligations 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 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. We may receive interim payments as work progresses, although for some contracts, we may be entitled to receive an advance payment. We recognize a liability for these 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 $101.6 million and $14.0 million as of July 1, 2018, and $110.3 million and $15.5 million as of January 1, 2018, respectively. 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, we record an unbilled receivable (contract asset) for the amount we are entitled to receive based on our enforceable right to payment. The unbilled receivable balance increased from the beginning of the year by $36.5 million, or 30.7%, primarily due to work performed ahead of billings on certain over time revenue contracts primarily in our Aerospace and Defense Electronics operating segment. Contract liabilities decreased from the beginning of the year by $10.3 million, or 8.1%, primarily due to the recognition of revenue in the year on customer advances that existed at the beginning of the year. The Company recognized revenue of $48.6 million during the quarter ended July 1, 2018 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 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 July 1, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was $1,632.6 million. The Company expects approximately 83% of remaining performance obligations to be recognized into revenue within the next twelve months, with the remaining 17% recognized thereafter.

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 USU.S. dollar value of future cash flows and minimize the volatility of reported earnings. All derivatives are recorded on the balance sheet at fair value. As discussed below, the accounting for gains and losses resulting from changes in fair value depends on the use of the derivative and whether it is designated and qualifies for hedge accounting. 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, including DALSA and in British pounds for our UK companies, including e2v. These contracts are designated and qualify as cash flow hedges. The Company has converted a USU.S. dollar denominated, variable rate debt obligation into a euro fixed rate obligation using a receive-float,receive float, pay fixed cross currency swap. This cross currency swap is designated as a cash flow hedge.
Cash Flow Hedging Activities
The effectiveness of the forward contract cash flow hedge, which exclude time value, and the cross currency swap cash flow hedge 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 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 cost of sales in our consolidated statements of income. For the cross currency swap cash flow hedge, effective amounts are recorded in AOCI, and reclassified into interest expense in the consolidated statements of income. In addition, for the cross currency swap an amount is reclassified from AOCI to other income and expense each reporting period, to offset the earnings impact of the remeasurement of the hedged liability. Net deferred losses recorded in AOCI, net of tax, for the forward contracts that will mature in the next twelve months total $0.3$1.2 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 swap expected to be reclassified from AOCI into income in the comingnext twelve months total $2.8$0.1 million.
In the event that the gains or losses in AOCI are deemed to be ineffective, the ineffective portion of gains or losses resulting from changes in fair value, if any, is reclassified to other income and expense. 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 July 1, 2018,March 31, 2019, Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $102.4$80.9 million. These foreign currency forward contracts have maturities ranging from September 2018June 2019 to FebruaryMay 2020. Teledyne had foreign currency forward contracts designated as cash flow hedges to buy British pounds and to sell U.S. dollars totaling $17.4 million.

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 secondfirst quarter and six months ended July 1, 2018March 31, 2019 was expenseincome of $17.0 million and $17.8 million, respectively.$1.6 million. The effect of derivative instruments not designated as cash flow hedges in other income and expense for the secondfirst quarter and six months ended July 2, 2017April 1, 2018 was expense of $0.5 million and $6.5 million, respectively. These losses were$0.8 million. The income/expense was largely offset by losses/gains in the value of the underlying hedged item.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):

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 non-qualifiedcommon stock, stock options and common stock, and beginning in 2015 restricted stock units have been issued to its directors. After 2014, non-employee directors no longer receive non-qualified stock options.
Stock Incentive Plan
The following disclosures are based on stock options granted to Teledyne’s employees and directors.

Stock option compensation expense was $10.3$8.9 million for the first six monthsquarter of 20182019 and was $7.8$4.9 million for the first six monthsquarter of 2017.2018. Employee stock option grants are charged to expense evenly over the three year vesting period.period except for stock options that were granted in 2019 to Teledyne’s President and Chief Executive Officer and Teledyne’s Executive Chairman which were expensed immediately. For 2018,2019, the Company currently expects approximately $21.1$26.6 million in stock option compensation expense based on stock options currently outstanding. 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.

Note 7. Inventories
Inventories are stated at current cost net of reserves for excess, slow moving and obsolete inventory, less progress payments. Inventories are valued under the FIFO method, LIFO method and average cost method. Inventories at cost determined on the average cost or the FIFO methods were $342.4$360.2 million at July 1, 2018March 31, 2019 and $348.6$331.3 million at December 31, 2017.30, 2018. The remainder of the inventories using the LIFO method were $46.9$41.9 million at July 1, 2018March 31, 2019 and $63.6$42.3 million at December 31, 2017.30, 2018. 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.

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 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 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 the first three months of 2019 and 2018 was approximately $2.8 million and $0.2 million of favorable operating income, primarily related to changes in estimates that favorably impacted revenue. 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 $111.2 million and $20.5 million as of March 31, 2019, and $111.5 million and $15.3 million as of December 30, 2018, respectively.
The Company recognized revenue of $35.4 million during the three months ended March 31, 2019 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 March 31, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $1,760.0 million. The Company expects approximately 79% of remaining performance obligations to be recognized into revenue within the next twelve months, with the remaining 21% recognized thereafter.
Product Warranty ReserveCosts
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 balance sheet.Condensed Consolidated Balance Sheet.

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.
On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Act”) was enacted. The Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As a result of the Tax Act, Teledyne incurred provisional charges of $4.7 million in the fourth quarter of 2017 primarily due to the repatriation tax and the remeasurement of U.S. deferred tax assets and liabilities. The impacts of the Tax Act may differ from this estimate, possibly materially (and the amount of the provisional charge may accordingly be adjusted over the course of 2018), due to changes in interpretations and assumptions Teledyne has made, guidance that may be issued, and actions Teledyne may take as a result of the Tax Act. In the first quarter of 2018, the provisional charge was adjusted by an additional $0.6 million.
The Company’s effective income tax rate for the secondfirst quarter and first six months of 20182019 was 17.7% and 18.3%, respectively.18.9%. The Company’s effective income tax rate for the secondfirst quarter and first six months of 2017 was 21.3% and 22.6%, respectively. The second quarter and first six months of 2018 includeswas 19.1%. The first quarter of 2019 and 2018 include net discrete income tax benefits of $3.4$3.1 million and $5.5$2.1 million, respectively. The 2018 second2019 first quarter and first six months net discrete tax benefits includes $4.7$2.9 million and $7.7 million, respectively, related to share-based accounting. The first six months of 2018 includes the first quarter $0.6 million increase in the provisional charge. The second quarter and first six months of 2017 included net discrete income tax benefits of $4.6 million and $6.0 million, respectively. The 2017 second quarter and first six months net discrete tax benefits includes an $8.1$3.0 million income tax benefit related to the release of valuation allowance for which the deferred tax assets are now determined more-likely-than-not to be realizable and $4.6 million in income tax expense related to adjustments for uncertain tax positions. The 2017 second quarter and first six months net discrete tax benefits includes $1.2 million and $2.8 million, respectively, related to share-based accounting. Excluding the net discrete income tax benefits in both periods and the increase in the provisional charge, the effective tax rates would have been 21.0% for the second quarter of 2018 and 21.3% for the first six months of 2018. Excluding net discrete income tax benefits in both 2017 periods, the effective tax rates would have been 27.4% for the second quarter and 27.7% for the first six months of 2017. The decrease in the effective tax rate in both 2018 periods, primarily reflects the lower corporate income tax rates as part of the Tax Act.

On March 15, 2019, Teledyne amended its $750.0 million credit agreement to extend the maturity date from December 2020 to March 2024. While the borrowing capacity remains at $750.0 million, the amendment permits Teledyne to increase the aggregate amount of the borrowing capacity by up to $250.0 million subject to certain conditions.
Available borrowing capacity under the $750.0 million credit facility, which is reduced by borrowings and certain outstanding letters of credit, was $674.9$571.2 million at July 1, 2018.March 31, 2019. The credit agreements require the Company to comply with various financial and operating covenants and at July 1, 2018,March 31, 2019, the Company was in compliance with these covenants.

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 July 1, 2018March 31, 2019 and December 31, 2017,30, 2018, approximated the carrying value.
At July 1, 2018, the Company had $6.0 million in capital leases, of which $1.3 million is current. At DecemberMarch 31, 2017, the Company had $6.7 million in capital leases, of which $1.3 million was current. At July 1, 2018,2019, Teledyne had $27.7$34.7 million in outstanding letters of credit.
Note 11. 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 31, 2017,30, 2018, included in the 20172018 Form 10-K.
At July 1,March 31, 2019, the Company’s reserves for environmental remediation obligations totaled $6.4 million, of which $1.5 million is included in current accrued liabilities. At December 30, 2018, the Company’s reserves for environmental remediation obligations totaled $4.7 million, of which $0.6 million is included in current accrued liabilities. At December 31, 2017, the Company’s reserves for environmental remediation obligations totaled $5.1$6.0 million. The Company periodically evaluates whether it may be able to recover a portion of future costs for environmental liabilities from its insurance carriers and from third parties. The timing of expenditures depends on a number of factors that vary by site, including the nature and extent of contamination, the number of potentially responsible parties, the timing of regulatory approvals, the complexity of the investigation and remediation, and the standards for remediation. The Company expects that it will expend present accruals over many years and will complete remediation of all sites with which it has been identified in up to 30 years.
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.

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.
On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Act”) was enacted. The Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As a result of the Tax Act, Teledyne incurred provisional charges of $4.7 million in the fourth quarter of 2017 primarily due to the repatriation tax and the remeasurement of U.S. deferred tax assets and liabilities. The impacts of the Tax Act may differ from this estimate, possibly materially (and the amount of the provisional charge may accordingly be adjusted over the course of 2018), due to changes in interpretations and assumptions Teledyne has made, guidance that may be issued, and actions Teledyne may take as a result of the Tax Act. In the first quarter of 2018, the provisional charge was adjusted by an additional $0.6 million.
The Company’s effective income tax rate for the secondfirst quarter of 20182019 was 17.7%18.9%, compared with 21.3% for the second19.1%. The first quarter of 2017. The second quarter of 20182019 reflected net discrete income tax benefits of $3.4 million. This amount includes$3.1 million, which included a $4.7$2.9 million income tax benefit related to share-based accounting. The 2017 secondfirst quarter net discrete tax benefits includes an $8.1 million income tax benefit related to the release of valuation allowance for which the deferred tax assets are now determined more-likely-than-not to be realizable and $4.6 million in income tax expense related to adjustments for uncertain tax positions. The 2017 second quarter also2018 included net discrete tax benefits includes $1.2of $2.1 million, which included a $3.0 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 21.0%22.3% for the secondfirst quarter of 20182019 and 27.4%21.7% for the secondfirst quarter of 2017. The decrease in the effective tax rate in both 2018 periods, primarily reflects the lower corporate income tax rates as part of the Tax Act.2018. The Company’s annual effective tax rate for fiscal year 20182019 is expected to be 21.3%22.3%, based on the projected mix of earnings before tax by jurisdiction, excluding the impact of any matters that would be treated as discrete.

The Company completedis 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 e2vacquisition of the scientific imaging businesses of Roper Technologies, Inc. since there was insufficient time between the acquisition date and SSI acquisitions, resulting in anthe end of the period to finalize the analysis.
On March 15, 2019, Teledyne amended its $750.0 million credit agreement to extend the maturity date from December 2020 to March 2024. While the borrowing capacity remains at $750.0 million, the amendment permits Teledyne to increase the aggregate amount of the borrowing capacity by up to goodwill of $3.9$250.0 million for e2v and $4.8 million for SSI in 2018.subject to certain conditions.
Financing activities usedprovided cash of $90.9$124.3 million for the first sixthree months of 2018,2019, compared with cash providedused by financing activities of $599.6 million for the first six months of 2017.$42.6 million. Financing activities for the first sixthree months of 2019 reflected net proceeds from the $750.0 million credit facility of $120.0 million. Financing activities for the first three months of 2018 reflected net payments against the $750.0 million credit facility of $115.0$54.5 million. Financing activities for the first six months of 2017 reflected net borrowings from the $750.0 million credit facility of $255.0 million and the proceeds from a $100.0 million term loan, primarily to fund the e2v acquisition. Proceeds from the exercise of stock options were $23.8$10.2 million and $11.7$12.3 million for the first sixthree months of 2019 and 2018, and 2017, respectively. In March 2017, Teledyne entered into a $100.0 million term loan with a maturity date of October 30, 2019. Subsequently, in March 2017, Teledyne entered into a cross currency swap to effectively convert the $100.0 million term loan to a 93.0 million Euro denominated instrument with a fixed euro interest rate of 0.7055%. The proceeds from the term loan were used in connection with the acquisition of e2v. Teledyne used the proceeds of the private placement to, among other things, repay indebtedness incurred in connection with the acquisition of e2v and for general corporate purposes.
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 other forms of 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 $90.0

million for capital expenditures in 2018,2019, of which $47.2$21.3 million has been spent in the first sixthree months of 2018.2019. No cash pension contributions have been made since 2013 or are planned for the remainder of 20182019 for the domestic qualified pension plan.
Total debt including capital lease obligations, at July 1, 2018March 31, 2019 was $952.0$856.4 million.

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 20172018 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 and divestitures, product sales, capital expenditures, pension matters, stock option compensation expense, the credit facility, interest expense, severance, and 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; 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; impacts from the United Kingdom’s decision topending exit from the European Union; uncertainties related to the policies of the U.S. Presidential Administration; the imposition and expansion of, and responses to, trade sanctions and tariffs;

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, including with respect to hydraulic fracturing, could further negatively affect the Company’scompany’s businesses that supply the oil and gas industry. Increasing fuel costs and disruptions from the grounding of Boeing's 737 Max aircraft could negatively affect the markets of our commercial aviation businesses. In addition, financial market fluctuations affect the value of the Company’scompany’s pension assets.
Information regarding the impact of the Tax Act consists of preliminary estimates which are forward-looking statements and are subject to change, possibly materially, as the company completes its financial statements. Information regarding the impact of the Tax Act is based on our current calculations, as well as our current interpretations, assumptions and expectations relating to the Tax Act, which are subject to change.
Changes in the policies of U.S. and foreign governments, could result, over time, in reductions and 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 outside of the United States, 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 20172018 Form 10-K and subsequentthis Quarterly ReportsReport 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 20172018 Form 10-K.
Market Risk
We are exposed to various market risks, including changes in foreign currency exchange rates and interest rates. Foreign currency forward contracts are used primarily to hedge anticipated exposures. We do not enter into derivatives or other financial instruments for trading or speculative purposes.
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 July 1, 2018March 31, 2019 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 $10.2$8.1 million. A hypothetical 10 percent price change in the U.S. dollar from its value at July 1, 2018March 31, 2019 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 $4.8 million. A hypothetical 10 percent price change in the U.S. dollar from its value at March 31, 2019 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 $10.1$10.5 million. For additional information please see Derivative Instruments discussed in Note 4 to these condensed consolidated financial statements.
Interest Rate Exposure
We are exposed to market risk through the interest rate on our borrowings under our $750.0 million credit facility and our $275.5$100.0 million in term loans. Borrowings under our credit facility and our term loans are at variable rates which are, at our option, tied to a Eurocurrency rate equal to LIBOR (London Interbank Offered Rate) plus an applicable rate or a base rate as defined in our credit agreements. Eurocurrency rate loans may be denominated in U.S. dollars or an alternative currency as defined in the credit agreements. Eurocurrency or LIBOR based loans under the credit facility typically have terms of one, two, three or nine months and the interest rate for each such loan is subject to change if the loan is continued or converted following the applicable maturity date. The Company has not drawn any loans with a term longer than three months under the credit facility. Base rate loans have interest rates that primarily fluctuate with changes in the prime rate. Interest rates are also subject to change based on our consolidated leverage ratio as defined in the credit agreements. As of July 1, 2018,March 31, 2019, we had $325.5$249.0 million in outstanding indebtedness under our credit facility and term loans. A 100 basis point increase in interest rates would result in an increase in annual interest expense of approximately $3.3$2.5 million, assuming the $325.5$249.0 million in debt was outstanding for the full year.

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 Chairman and 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 July 1, 2018,March 31, 2019, are effective at the reasonable assurance level.
In connection with our evaluation during the quarterly period ended July 1, 2018,March 31, 2019, 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.



PART II OTHER INFORMATION
Item 1.Legal Proceedings
See Item 1 of Part 1, “Financial Statements -- Note 11 -- Lawsuits, Claims, Commitments, Contingencies and Related Matters.”
 Item 1A.Risk Factors
Other than as set forth below, thereThere are no material changes to the risk factors previously disclosed in our 20172018 Form 10-K in response to Item 1A to Part 1 of Form 10-K. See also Part I Item 3, Quantitative and Qualitative Disclosures About Market Risk, for updated disclosures about interest rate exposure and exchange rate risks.
Escalating trade tensions and the adoption or expansion of tariffs and trade restrictions could negatively impact us.
The U.S. Presidential Administration has recently announced tariffs on steel and aluminum products and materials imported into the United States. The Administration has also implemented or announced plans to impose tariffs on a wide-range of goods imported from China. Various countries and economic regions have announced plans or intentions to impose retaliatory tariffs on a wide-range of products they import from the U.S. These newly imposed or threatened U.S. tariffs and retaliatory tariffs could have the effect of increasing the cost of materials for our products, which could result in our products becoming less competitive or generating lower margins. The tariffs could also result in disruptions to our supply chain, as suppliers struggle to fill orders from companies trying to purchase goods in bulk ahead of announced tariffs. We may also need to find new suppliers and components for our products, which could result in production delays. While none of our products are currently the subject of retaliatory tariffs, they could be in the future, and customers in some countries or regions, such as China, may begin to seek domestic or non-U.S. sources for products that we sell, or be pressured or incentivized by foreign governments not to purchase U.S.-origin goods, which could harm our future sales in these markets. The Administration has also indicated its desire to renegotiate certain international trade agreements, which if carried out could result in additional disruptions to our supply chain.

Item 2.Unregistered sales of equity securities and use of proceeds
The Teledyne Technologies Incorporated Employee Stock Purchase Plan (the “Plan”) allows employees to purchase shares of Teledyne common stock through regular payroll deductions.  The Plan includes a 25% employer matching feature. The Plan administrator purchases shares of Teledyne common stock on the open market, and then allocates the shares to participants’ Plan accounts. In March 2018, we determined that participants in the Plan may have purchased more shares of Teledyne common stock than were registered under the Securities Act of 1933. We did not receive any consideration in connection with such purchases, which were funded with participants’ payroll deduction plus the employer match. On April 27, 2018, we filed a registration statement on Form S-8 to register future transactions by the Plan.

Item 5.Other Information
On August 1, 2018, Teledyne and two senior executives, including Thomas H. Reslewic, President of Teledyne’s Environmental and Electronic Measurement Instrumentation (EEMI) and Defense Electronics Groups, entered into Change in Control Severance Agreements. The Change in Control Severance Agreements, which were authorized by Teledyne’s Board with assistance from independent compensation consultants, are substantially similar to agreements entered into with Teledyne’s other named executives and certain senior executive officers. The Change in Control Severance Agreements have a three-year, automatically renewing terms. Each executive is entitled to severance benefits if (1) there is a change in control of the Company and (2) within three months before or 24 months after the change in control, either we terminate the executive’s employment for reasons other than cause or the executive terminates his employment for good reason. “Severance benefits” for each executive currently consist of:  
ŸA cash payment equal to two times the sum of (i) the executive’s highest annual base salary within the year preceding the change in control and (ii) the Annual Incentive Plan bonus target for the year in which the change in control occurs or the average actual bonus payout for the three years immediately preceding the change in control, whichever is higher.
ŸA cash payment for the current Annual Incentive Plan bonus cycle based on the fraction of the year worked times the Annual Incentive Plan target objectives at 100% (with payment of the prior year bonus if not yet paid).
ŸPayment in cash for unpaid PSP awards, assuming applicable goals are met at 100% of performance.
ŸContinued equivalent health and welfare (e.g., medical, dental, vision, life insurance and disability) benefits at our expense for a period of up to 24 after termination (with the executive bearing any portion of the cost the executive bore prior to the change in control); provided, however, such benefits would be discontinued to the extent the executive receives similar benefits from a subsequent employer.
ŸRemoval of restrictions on performance-based restricted stock issued under our restricted stock award programs.
ŸUp to $15,000 reimbursement for actual professional outplacement services.
ŸImmediate vesting of all stock options, with options being exercisable for the full remainder of the term.
ŸIn the event amounts under the agreements constitute an “excess parachute” payment as defined in Section 280G of the Internal Revenue Code, the executive will receive the better of, on an after-tax basis, (a) the unreduced excess parachute payment with no tax gross up payment, or (b) a parachute payment reduced to a level below which an excise tax is imposed.
For the purposes of the Change in Control Severance Agreement, a “change in control” will generally be deemed to occur if (1) the Company acquires actual knowledge that any person or group of persons acting together has acquired the beneficial ownership of securities of the Company entitling such person to 20% or more of the voting power of the Company, (2) a tender offer to acquire 20% or more of the voting power of the Company is completed, (3) a successful third party proxy solicitation is made relating to the election or removal of 50% or more of the members of the Board or any class of the Board, or (4) a merger, consolidation, share exchange, division or sale or other disposition of assets of the Company occurs as a result of which the stockholders of the Company immediately prior to such transaction do not hold, immediately following such transaction, a majority of the voting power of the surviving, acquiring or resulting corporation.
A copy of the Change in Control Severance Agreements with Mr. Reslewic (who is a named executive in Teledyne's 2018 Proxy Statement) is attached as Exhibit 10.1 to this Quarterly Report and incorporated herein by reference.
