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.

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.

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.

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.

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.

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.

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.

a)    Effective portion, pre-tax

b)     Amount reclassified to offset earnings impact of liability hedged by cross currency swap

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.

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.
