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 as they apply to interim reporting. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes in Teledyne’s Annual Report on Form 10-K for the fiscal year ended January 3, 2016 (“2015 Form 10-K”). In the opinion of Teledyne’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, Teledyne’s consolidated financial position as of October 2, 2016 and the consolidated results of operations and consolidated comprehensive income for the three and nine months then ended and cash flows for the nine months then ended. The results of operations and cash flows for the periods ended October 2, 2016 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 third quarter of 2016, Teledyne sold assets of the Printed Circuit Technology (“PCT”) business for $9.3 million in cash. As a result, these financial statements reflect the classification of our PCT business as a discontinued operation. See Note 14 to these condensed consolidated financial statements for additional information. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting. The ASU is intended to simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted for any entity in any interim or annual period. Teledyne elected to adopt early this ASU in the third quarter of 2016, therefore Teledyne is required to report the material impacts of this standard as though the ASU had been adopted at the beginning of the fiscal year. Accordingly, Teledyne recognized additional income tax benefits as an increase to net income of $4.0 million and $5.8 million during the third quarter and nine months ended October 2, 2016. The adjustments for the third quarter included only the quarterly impacts, whereas the adjustments for the first nine months of 2016 include the first and second quarter additional income tax benefits of $0.6 million and $1.2 million, respectively and the immaterial impact for reclassification of amounts from financing activities to operating activities in the condensed consolidated statement of cash flows. Teledyne has elected to record forfeitures as they occur, which did not have a material impact on the condensed consolidated financial results. The new guidance did not impact any periods prior to our 2016 fiscal year, as the changes were applied on a prospective basis. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. In July 2015, the FASB deferred the effective date by one year, but will allow early adoption as of the original adoption date. This new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is currently in the process of determining its implementation approach and evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new guidance will require lessees to recognize almost all 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 will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The new guidance must be adopted using a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.
