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 notes thereto in Teledyne’s Annual Report on Form 10-K for the fiscal year ended December 29, 2013 (“2013 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 29, 2014 and the consolidated results of operations and consolidated comprehensive income for the second quarter and six months then ended and consolidated cash flows for six months then ended. The results of operations and cash flows for the periods ended June 29, 2014 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year.
	Recent Accounting Pronouncements
	Effective December 30, 2013, the Company adopted accounting guidance related to the presentation of an unrecognized tax benefit when a net operating loss carryforward (“NOL”), a similar tax loss or a tax credit carryforward exists. Under the guidance, an entity will be required to present an unrecognized tax benefit as a reduction of a deferred tax asset for a NOL or tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. The Company's adoption of the guidance, did not have a material impact on its consolidated financial statements.
	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 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. This new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early application not permitted. The Company is currently in the process of determining its implementation approach and assessing the impact on the consolidated financial statements and footnote disclosures.

	Business Combinations and Investments, Goodwill and Acquired Intangible Assets
	On March 31, 2014, a subsidiary of Teledyne acquired Photon Machines, Inc. (“Photon”) for an initial payment of $3.3 million. Teledyne expects to pay an additional $0.7 million in equal installments over the next three years.
	On October 22, 2013, a subsidiary of Teledyne acquired C.D. Limited (“CDL”) for $21.8 million in cash, net of cash acquired. On August 30, 2013, a subsidiary of Teledyne acquired the assets of SD Acquisition, Inc. d/b/a CETAC Technologies (“CETAC”) for $26.4 million. Teledyne paid a $0.4 million purchase price adjustment in the fourth quarter of 2013. On July 5, 2013, a subsidiary of Teledyne purchased the remaining 49% interest in Nova Research, Inc. (“Nova Sensors”) that it did not already own for $4.9 million. On May 8, 2013, a subsidiary of Teledyne acquired Axiom IC B.V. (“Axiom”), for an initial payment of $4.0 million, net of cash acquired, with an additional $1.3 million expected to be paid in equal installments over three years. The first of the three installments was made in May 2014. On March 1, 2013, a subsidiary of Teledyne acquired all the outstanding shares of RESON A/S (“RESON”) for $69.7 million, net of cash acquired. CDL, CETAC and RESON are part of the Instrumentation segment and Nova Sensors and Axiom are part of the Digital Imaging segment.
	Teledyne funded the purchases from borrowings under its credit facility and cash on hand. The results of the acquisitions have been included in Teledyne’s results since the dates of the respective acquisition.
	For a further description of the Company’s acquisition activity for the fiscal year ended December 29, 2013, please refer to Note 3 of our 2013 Form 10-K.
	Teledyne’s goodwill was $1,042.8 million at June 29, 2014 and $1,037.8 million at December 29, 2013. The increase in the balance of goodwill in 2014 resulted from the impact of exchange rate changes and the Photon acquisition. Except for the CETAC acquisition, goodwill resulting from the acquisitions made in fiscal 2014 and 2013 will not be deductible for tax purposes. Teledyne’s net acquired intangible assets were $258.4 million at June 29, 2014 and $270.9 million at December 29, 2013. The decrease in the balance of acquired intangible assets in 2014 primarily resulted from amortization, partially offset by acquired intangibles for the Photon acquisition. The Company is in the process of specifically identifying the amounts assigned to certain assets and liabilities, acquired intangible assets and the related impact on goodwill for the Photon 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 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 revenues and expenses denominated in Canadian dollars. These contracts are designated and qualify as cash flow hedges.
	Cash Flow Hedging Activities
	The effectiveness of the cash flow hedge contracts, excluding time value, is assessed prospectively and retrospectively on a monthly basis using regression analysis, as well as using other timing and probability criteria. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedges and must be highly effective in offsetting changes to future cash flows on hedged transactions. The effective portion of the cash flow hedge contracts’ gains or losses resulting from changes in the fair value of these hedges is initially reported, net of tax, as a component of AOCI in stockholders’ equity until the underlying hedged item is reflected in our consolidated statements of income, at which time the effective amount in AOCI is reclassified to cost of sales in our consolidated statements of income. Net deferred gains recorded in AOCI, net of tax, for contracts that will mature in the next twelve months total $0.2 million. These gains are expected to be offset by anticipated losses in the value of the forecasted underlying hedged item.
	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 June 29, 2014, Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $83.7 million. These foreign currency forward contracts have maturities ranging from July 2014 to November 2015.
	Non-Designated Hedging Activities
	In addition, the Company utilizes foreign currency forward contracts to mitigate foreign exchange rate risk associated with foreign-currency-denominated monetary assets and liabilities, including intercompany receivables and payables. As of June 29, 2014, Teledyne had foreign currency contracts of this type in the following pairs (in millions):
	Contracts to Buy					Contracts to Sell
	Currency	Amount				Currency	Amount
	Canadian Dollars	C$	55.8			U.S. Dollars	US$	51.1
	Great Britain Pounds	£	14			U.S. Dollars	US$	23.5

	Singapore Dollars	S$	0.8			U.S. Dollars	US$	0.7
	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. 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. Teledyne does not use foreign currency forward contracts for speculative or trading purposes.
	The effect of derivative instruments designated as cash flow hedges in our condensed consolidated financial statements for the second quarter and six months ended June 29, 2014 and June 30, 2013 was as follows (in millions):
		Second Quarter								Six Months

	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 29, 2014 was $1.7 million and $1.2 million of gain, respectively. 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 30, 2013 was $0.7 million and $1.6 million of expense, respectively.

	Earnings Per Share
	Basic and diluted earnings per share were computed based on net earnings. The weighted average number of common shares outstanding during the period was used in the calculation of basic earnings per share. This number of shares was increased by contingent shares that could be issued under various compensation plans as well as by the dilutive effect of stock options based on the treasury stock method in the calculation of diluted earnings per share.
	For the second quarter and six months of 2014 and 2013, no stock options were excluded in the computation of diluted earnings per share. The following table sets forth the computations of basic and diluted earnings per share (amounts in millions, except per share data):

For the second quarter and first six months of 2013, the company recorded a total of $2.8 million and $4.6 million, in stock option compensation expense, respectively. Employee stock option grants are charged to expense evenly over the three year vesting period. Director stock option grants are charged to expense evenly over the one-year vesting period. For 2014, the Company currently expects approximately $14.5 million in stock option compensation expense based on stock options already granted and current assumptions regarding the estimated fair value of stock option grants expected to be issued during the remainder of the year. However, our assessment of the estimated compensation expense will be affected by our stock price, actual stock option grants during the remainder of the year and employee retirements and termination as well as assumptions regarding a number of complex and subjective variables and the related tax impact. These variables include, but are not limited to, the volatility of our stock price and employee stock option exercise behaviors. The Company issues shares of common stock upon the exercise of stock options.
	The Company uses its historical stock price volatility on the Company stock to compute the expected volatility for purposes of valuing stock options issued. The period used for the historical stock price corresponded to the expected term of the options and was seven years, five months. The expected dividend yield is based on Teledyne’s practice of not paying dividends. The risk-free rate of return is based on the yield of U. S. Treasury Strips with terms equal to the expected life of the options as of the grant date. The expected life in years is based on historical actual stock option exercise experience.
	The following assumptions will be used in the valuation of stock options granted in 2014 and 2013:
		2014		2013
	Expected dividend yield	—		—
	Expected volatility	30.7	%	31.9	%
	Risk-free interest rate	1.7	%	0.9	%
	Expected life in years	7.4		7.3
	Based on the assumptions in the table above, the grant date weighted average fair value of stock options granted in 2014 and 2013 was $36.24 and $27.17, respectively.

Inventories	'
	Inventories
	Inventories are stated at the lower of cost or market, 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 $244.4 million at June 29, 2014 and $240.2 million at December 29, 2013. The remainder of the inventories using the LIFO method were $100.8 million at June 29, 2014 and $83.4 million at December 29, 2013. 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 are subject to many factors beyond the Company’s control, interim results are subject to the final year-end LIFO inventory valuation. Inventories consist of the following (in millions):
	Balance at	29-Jun-14			29-Dec-13
	Raw materials and supplies	$	138.2		$	130.7

	During 2013, in an effort to reduce ongoing costs and improve operating performance, the Company took actions to consolidate and relocate certain facilities and reduce headcount across various businesses. The actions taken were substantially completed by year end 2013. At June 29, 2014 and December 29, 2013, the Company had $8.8 million and $11.4 million in short-term reserves related to these actions.
	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 pre-existing warranty liabilities 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, which are typically one year. The product warranty reserve is included in current and long term accrued liabilities on the balance sheet. Changes in the Company’s product warranty reserve during the first six months of 2014 and 2013 are as follows (in millions):

Income Taxes	'
	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 six months of 2014 was 28.3% and 27.2%, respectively. The Company's effective income tax rate for the second quarter and six months of 2013 was 27.6% and 26.3%, respectively. The second quarter of 2014 included net tax expense for discrete items of $0.2 million and the first six months of 2014 included net tax benefits for discrete items of $2.1 million, compared with net tax benefits for discrete items of $0.9 million and $3.6 million for the second quarter and first six months of 2013, respectively. The net tax benefits for the first six months of 2014 included the remeasurement of uncertain tax positions due to a favorable resolution of a tax matter. The net tax benefits in 2013 primarily related to the retroactive reinstatement of certain tax benefits and credits from the enactment of the American Taxpayer Relief Act of 2012 signed into law on January 2, 2013. Excluding net discrete tax benefits/expense in all periods, the effective tax rates would have been 28.1% for the second quarter and 28.7% for the first six months of 2014 and 29.1% for the second quarter of 2013 and 29.5% for the first six months of 2013.
	During the next twelve months, it is reasonably possible that expirations of the statutes of limitations could reduce unrecognized tax benefits by $4.9 million. Of the $4.9 million, $0.1 million would not impact tax expense as it would be offset by the reversal of deferred tax assets.

The credit agreement requires the Company to comply with various financial and operating covenants and at June 29, 2014, 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 estimated fair value of Teledyne’s long-term debt at June 29, 2014 and December 29, 2013, approximated the carrying value.
	As June 29, 2014, the Company has $11.9 million in capital leases, of which $1.4 million is current. At December 29, 2013, the Company had $12.3 million in capital leases, of which $1.4 million was current. At June 29, 2014, Teledyne had $15.5 million in outstanding letters of credit.

	At June 29, 2014, the Company’s reserves for environmental remediation obligations totaled $8.6 million, of which $5.5 million is included in current accrued liabilities. 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, commercial 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 condition. The resolution in any reporting period of one or more of these matters could have a material adverse effect on the Company’s results of operations for that period.

	Pension Plans and Postretirement Benefits
	Teledyne’s pension income was $0.4 million and $0.7 million for the second quarter and first six months of 2014, respectively, compared with pension expense of $4.4 million and $8.7 million for the second quarter and first six months of 2013, respectively. The change to pension income in 2014, from pension expense in 2013, primarily reflected the impact of using a 5.4 percent discount rate to determine the benefit obligation for the domestic plan in 2014 compared with a 4.4 percent discount rate used in 2013. Pension expense allocated to contracts pursuant to U.S. Government Cost Accounting Standards (“CAS”) was $3.4 million and $6.9 million for the second quarter and first six months of 2014, respectively, compared with $3.6 million and $7.2 million for the second quarter and first six months of 2013, respectively. Pension expense determined under CAS can generally be recovered through the pricing of products and services sold to the U.S. Government. Teledyne did not make any cash pension contributions to its domestic pension plan in the first six months of 2014, compared with voluntary pretax cash pension contributions totaling $83.0 million to its domestic pension plan in the first six months of 2013. No cash pension contributions are planned for 2014 for the domestic pension plan.
	The Company sponsors several postretirement defined benefit plans that provide health care and life insurance benefits for certain eligible retirees.

	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 notes thereto in Teledyne’s Annual Report on Form 10-K for the fiscal year ended December 29, 2013 (“2013 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 29, 2014 and the consolidated results of operations and consolidated comprehensive income for the second quarter and six months then ended and consolidated cash flows for six months then ended.

Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	Effective December 30, 2013, the Company adopted accounting guidance related to the presentation of an unrecognized tax benefit when a net operating loss carryforward (“NOL”), a similar tax loss or a tax credit carryforward exists. Under the guidance, an entity will be required to present an unrecognized tax benefit as a reduction of a deferred tax asset for a NOL or tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. The Company's adoption of the guidance, did not have a material impact on its consolidated financial statements.
	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 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. This new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early application not permitted. The Company is currently in the process of determining its implementation approach and assessing the impact on the consolidated financial statements and footnote disclosures.
