	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 30, 2012 (“2012 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 September 29, 2013 and the consolidated results of operations, consolidated comprehensive income third quarter and nine months then ended and consolidated cash flows for the nine months then ended. The results of operations and cash flows for the period ended September 29, 2013 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 31, 2012, the Company adopted accounting guidance on the testing of indefinite-lived intangible assets for impairment. The guidance allows entities to first perform a qualitative assessment to determine the likelihood of an impairment for an indefinite-lived intangible asset and whether it is necessary to perform the quantitative impairment assessment currently required. The Company’s adoption of this guidance did not have any impact on Teledyne's financial position, results of operations or cash flows.
	Effective December 31, 2012, the Company adopted accounting guidance which updates the presentation of reclassifications from comprehensive income to net income in consolidated financial statements. Under this guidance, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income (“AOCI”) either by the respective line items of net income or by cross-reference to other required disclosures. The guidance does not change the requirements for reporting net income or other comprehensive income in financial statements. As the guidance relates to presentation only, the adoption did not have any impact on Teledyne's financial position, results of operations or cash flows.
	The changes in AOCI by component, net of tax, for the third quarter and first nine months ended September 29, 2013 are as follows (in millions):

	Business Combinations and Investments, Goodwill and Acquired Intangible Assets
	Teledyne spent $106.4 million and $389.2 million on acquisitions in the first nine months of 2013 and 2012, respectively.
	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 expects to pay a $0.4 million purchase price adjustment in the fourth quarter. CETAC, headquartered in Omaha, Nebraska is a designer and manufacturer of automated sample handling and sample introduction equipment for laboratory instrumentation. CETAC had sales of $24.0 million for its fiscal year ended December 31, 2012, and is part of the Instrumentation segment.
	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. Nova Sensors is part of the Digital Imaging segment. In the third quarter of 2013, the Company spent $1.4 million on certain assets.
	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. Axiom is located in the Netherlands and is a fabless semiconductor company that develops high-performance CMOS mixed-signal integrated circuits and is part of the Digital Imaging segment.
	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. RESON, headquartered in Slangerup, Denmark, provides multibeam sonar systems and specialty acoustic sensors for hydrography, global marine infrastructure and offshore energy operations. RESON had sales of €50.8 million for its fiscal year ended December 31, 2012 and is part of the Instrumentation segment.
	On August 3, 2012, Teledyne acquired LeCroy Corporation (“LeCroy”) for $301.3 million, net of cash acquired. LeCroy, headquartered in Chestnut Ridge, New York is a leading supplier of oscilloscopes, protocol analyzers and signal integrity test solutions. LeCroy is part of the Instrumentation segment.
	Also on August 3, 2012, a subsidiary of Teledyne acquired the parent company of PDM Neptec Limited (“PDM Neptec”) for $7.4 million in cash, net of cash acquired.  PDM Neptec, located in Hampshire, United Kingdom, is part of the Instrumentation segment and operates as Teledyne Impulse-PDM Ltd.
	On July 2, 2012, a subsidiary of Teledyne acquired BlueView Technologies Inc. (“BlueView”) for $16.3 million in cash, net of cash acquired. BlueView, located in Seattle, Washington, is part of the Instrumentation segment and operates as Teledyne BlueView, Inc.
	On April 2, 2012, a subsidiary of Teledyne acquired a majority interest in the parent company of Optech Incorporated (“Optech”) for $27.9 million, net of $4.8 million in cash acquired. The purchase increased Teledyne’s ownership percentage to 51 percent from the original 19 percent interest purchased in the first quarter of 2011. With the April 2012 purchase, we now consolidate Optech’s financial results into Teledyne’s results with an appropriate adjustment for the minority ownership. At the time of the purchase, the value of Optech’s total equity was based on the same per share price as those shares purchased by Teledyne to obtain the majority interest in 2012 and the value of the non-controlling interest was 49.0% of Optech’s total equity and was equal to $49.8 million. The minority ownership of Optech was $49.2 million and $49.8 million at September 29, 2013 and December 30, 2012, respectively. Optech is part of the Digital Imaging segment.
	On February 25, 2012, Teledyne acquired VariSystems Inc. (“VariSystems”) for $34.9 million, net of cash acquired. Teledyne paid a $1.4 million purchase price adjustment in the second quarter of 2012. VariSystems, headquartered in Calgary, Alberta, Canada, supplies custom harsh environment interconnects used in energy exploration and production. VariSystems is part of the Digital Imaging segment.
	Teledyne funded the purchases primarily from borrowings under its credit facility and cash on hand. The results of these acquisitions have been included in Teledyne’s results since the dates of the respective acquisitions.
	Teledyne’s goodwill was $1,030.3 million at September 29, 2013 and $990.2 million at December 30, 2012. The increase in the balance of goodwill in 2013 resulted from the CETAC, RESON and Axiom acquisitions partially offset by the impact of exchange rate changes and also reflected a $4.9 million reduction related to a purchase accounting adjustment for the LeCroy acquisition. In the second quarter of 2013, the Company identified an immaterial misstatement in purchase accounting related to the 2012 LeCroy acquisition after the allocation period had ended. The Company increased long term deferred tax assets by $4.9 million and reduced goodwill by the same amount in the second quarter of 2013. Teledyne’s net acquired intangible assets were $274.2 million at September 29, 2013 and $265.7 million at December 30, 2012. The increase in the balance of acquired intangible assets in 2013 primarily resulted from the CETAC and RESON acquisitions, partially offset by amortization and the impact of exchange rate changes. The Company’s cost to acquire CETAC, RESON and Axiom has been allocated to the assets acquired and liabilities assumed based upon their respective fair values as of the date of the completion of the acquisition. The differences between the fair value of the consideration paid and the estimated fair value of the assets and liabilities acquired has been recorded as goodwill. The Company has completed the process of specifically identifying the amounts assigned to assets and liabilities and acquired intangible assets and the related impact on goodwill for the RESON and Axiom acquisitions. The Company is still in the process of specifically identifying the amount to be assigned to certain liabilities and the related impact on taxes and goodwill for the CETAC acquisition. The Company made preliminary estimates as of September 29, 2013, since there was insufficient time between the acquisition date and the end of the period to finalize the analysis.
	The following is a summary at the acquisition date of the estimated fair values allocated to the assets acquired and liabilities assumed for the acquisitions made in 2013, excluding the purchase of the remaining 49% interest in Nova Sensors. (in millions):
	Current assets	$	36
	Property, plant and equipment	5.8
	Goodwill	50.6
	Acquired intangible assets	32.8
	Current liabilities	(18.7		)
	Long-term liabilities	(5.0		)
	Net assets acquired	$	101.5
	Except for the CETAC acquisition, goodwill resulting from the acquisitions made in 2013 and 2012 will not be deductible for tax purposes.
	The following table is a summary at the acquisition date of the acquired intangible assets and weighted average useful life in years for the acquisitions made in 2013, excluding the purchase of the remaining 49% interest in Nova Sensors (dollars in millions):
		Amount			Weighted Average Useful Life in Years

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 revenue 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. The Company expects to reclassify a loss of approximately $0.1 million over the next 12 months based on the September 29, 2013 exchange rate.
	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 September 29, 2013, Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $81.1 million and these contracts had a fair value of $0.2 million. These foreign currency forward contracts have maturities ranging from December 2013 to February 2015.
	Non-Designated Hedging Activities
	In addition, the Company utilizes foreign currency forward contracts to mitigate foreign exchange rate risk associated with foreign-currency-denominated monetary assets and liabilities, including intercompany receivables and payables. As of September 29, 2013, Teledyne had foreign currency contracts of this type in the following pairs (in millions):
	Contracts to Buy						Contracts to Sell
	Currency		Amount				Currency		Amount
	Canadian Dollars		C$	35.4			U.S. Dollars		US$	34.3
	Great Britain Pounds		£	12.7			U.S. Dollars		US$	19.8
	U.S. Dollars		US$	12.2			Euros		€	9.2

	Japanese Yen		¥	86			Canadian Dollars		C$	0.9
	Singapore Dollars		S$	0.9			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 third quarter and nine months ended September 29, 2013 and September 30, 2012 was as follows (in millions):
		Third Quarter								Nine Months

	(a)	Effective portion
	(b)	Amount excluded from effectiveness testing
	The effect of derivative instruments not designated as cash flow hedges recognized in other income and expense for the third quarter and nine months ended September 29, 2013 was a benefit of $1.0 million and an expense of $0.6 million respectively. The effect of derivative instruments not designated as cash flow hedges recognized in other income and expense for the third quarter and nine months ended September 30, 2012 was a benefit of $0.6 million and $0.4 million, 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 third quarter and first nine months of 2013 and 2012, 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):

	Stock-Based Compensation Plans
	Teledyne has long-term incentive plans pursuant to which it has granted non-qualified stock options, restricted stock and performance shares to certain employees. The Company also has non-employee director stock compensation plans, pursuant to which non-qualified stock options and common stock have been issued to its directors.
	Stock Incentive Plan
	The following disclosures are based on stock options granted to Teledyne’s employees and directors. The Company recorded a total of $3.0 million and $7.6 million in stock option compensation expense for the third quarter and first nine months of 2013, respectively. For the third quarter and first nine months of 2012, the company recorded a total of $2.3 million and $5.9 million, 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. In 2013, the Company currently expects approximately $10.8 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 and actual stock option grants during the remainder of the year 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 a combination of its historical stock price volatility and the volatility of exchange traded options, if any, 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, three months. The period used for the exchange traded options, if any, included the longest-dated options publicly available, generally three 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 were used in the valuation of stock options granted in 2013 and 2012:
		2013		2012
	Expected dividend yield	—		—
	Expected volatility	31.9	%	34.1	%
	Risk-free interest rate	0.9	%	1.1	%
	Expected life in years	7.3		6.7
	Based on the assumptions in the table above, the grant date weighted average fair value of employee stock options granted in 2013 and 2012 was $27.17 and $23.90, respectively.

	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 $241.9 million at September 29, 2013 and $214.3 million at December 30, 2012. The remainder of the inventories using the LIFO method were $89.6 million at September 29, 2013 and $91.5 million at December 30, 2012. 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-Sep-13			30-Dec-12
	Raw materials and supplies	$	135.6		$	129.4

	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. In connection with these efforts, for the first nine months of 2013, the Company incurred pretax charges totaling $18.7 million for severance and facility consolidation expense and environmental reserves. The charges were comprised of $7.0 million in severance related costs, $11.7 million in facility closure and relocation costs, which included $5.3 million of environmental reserves. The actions taken should be substantially complete by year end 2013. Total costs for these actions are expected to be $22.4 million for fiscal year 2013. At September 29, 2013, the Company has $11.1 million in short-term reserves related to these actions, which includes the $5.3 million of environmental reserves.
	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 nine months of 2013 and 2012 are as follows (in millions):

	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 third quarter and first nine months of 2013 was 0.6% and 18.8%, respectively. The Company's effective income tax rate for the third quarter and first nine months of 2012 was 24.5% and 28.4%, respectively. The third quarter and first nine months of 2013 included net tax benefits for discrete items of $11.6 million and $15.2 million, respectively, compared with net tax benefits for discrete items of $3.1 million for the third quarter of 2012 and $4.3 million for the first nine months of 2012. The tax benefits for the third quarter and first nine months of 2013, included the remeasurement of uncertain tax positions, including expiration of statute of limitations and a favorable resolution of a tax matter. The tax benefits for the third quarter and first nine months of 2012, included the expiration of statute of limitations. Excluding net discrete tax benefits in all periods, the effective tax rates would have been 25.2% for the third quarter of 2013 and 28.3% for the first nine months of 2013 and 30.0% for the third quarter of 2012 and 31.0% for the first nine months of 2012. The decrease in the effective tax rates in both periods primarily reflected a change in the proportion of domestic and foreign income.
	The Company has substantially concluded on all U.S. federal income tax matters for all years through 2009, California income tax matters for all years through 2006 and all material Canadian income tax matters for all years through 2010. The Company is currently under audit in California for tax years 2007 through 2009 and in Florida for tax years 2009 through 2011. The Company does not believe that the resolution of any of the audits will have a material adverse effect on the Company’s results of operations. Substantially all other material state and foreign income tax matters have been concluded for years through 2006. The Company’s intention is to indefinitely reinvest the earnings of its material non-U.S. subsidiaries.

	Long-Term Debt and Capital Leases
	In March 2013, the Company amended its $550.0 million credit facility to increase the borrowing capacity to $750.0 million and extend the maturity date from February 2016 to March 1, 2018. The other material terms of the credit facility, including covenants, remain unchanged. Excluding interest and fees, no payments are due under the credit facility until it matures. In October 2012, Teledyne entered into $200.0 million of term loans that mature in October 2015. The proceeds were applied against the then $550.0 million revolving credit facility. The credit agreements require the Company to comply with various financial and operating covenants, including maintaining certain consolidated leverage and interest coverage ratios. Borrowings under our credit facility and 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 agreement. Eurocurrency or LIBOR based loans under the facility typically have terms of one, two, three or six 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 agreement. The credit agreement also provides for facility fees that vary between 0.125% and 0.30% of the credit line, depending on our consolidated leverage ratio as calculated from time to time.
	Available borrowing capacity under the $750.0 million credit facility, which is reduced by borrowings and certain outstanding letters of credit, was $574.8 million at September 29, 2013. The credit agreement requires the Company to comply with various financial and operating covenants and at September 29, 2013, the Company was in compliance with these covenants. Teledyne also has a $5.0 million uncommitted credit line which permits credit extensions up to $5.0 million plus an incremental $2.0 million solely for standby letters of credit. No amounts were outstanding under this credit line at September 29, 2013 or December 30, 2012. This credit line is utilized, as needed, for periodic cash needs. 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 September 29, 2013 and December 30, 2012, approximated the carrying value.
	Long-term debt consisted of the following (in millions):
	Balance at	September 29, 2013		December 30, 2012
	4.04% Notes due September 2015	$	75	$	75

	At September 29, 2013, the Company’s reserves for environmental remediation obligations totaled $8.7 million, of which $5.7 million is included in current accrued liabilities. The increase in the third quarter of 2013 includes the $5.3 million in environmental reserves recorded in connection with the facility closure and relocation costs. 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, employment and employee benefits. 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.
	In March 2009, Cold Creek Enterprises, Inc. and Bob DaSilva commenced a lawsuit against DALSA Corporation and certain related entities in the Ontario Superior Court of Justice. The claims originate from the interest of Mr. DaSilva’s company in DALSA Digital Camera Inc., a joint venture entered into in November 2004 and a discontinued business of DALSA since the third quarter of 2008. The lawsuit seeks various forms of relief, including damages in excess of CAD $20.0 million. The lawsuit is being vigorously defended, and a counterclaim has been filed against the plaintiff.

	Teledyne’s pension expense was $4.3 million and $13.0 million for the third quarter and first nine months of 2013, respectively, compared with pension expense of $1.7 million and $5.0 million the third quarter and first nine months of 2012, respectively. The increase in pension expense primarily reflected the impact of using a 4.4 percent discount rate to determine the benefit obligation for the domestic plan in 2013 compared with a 5.5 percent discount rate used in 2012. Pension expense allocated to contracts pursuant to U.S. Government Cost Accounting Standards (“CAS”) was $3.6 million and $10.8 million for the third quarter and first nine months of 2013, respectively, compared with $3.1 million and $9.0 million for the third quarter and first nine months of 2012, respectively. Pension expense determined under CAS can generally be recovered through the pricing of products and services sold to the U.S. Government. Teledyne made a voluntary cash pension contribution of $83.0 million to its domestic pension plan in the first nine months of 2013, compared with voluntary cash pension contributions totaling $92.8 million to its domestic pension plan in the first nine months of 2012. No further cash pension contributions are planned for the remainder of 2013 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.

	Industry Segments
	Teledyne is a leading provider of sophisticated instrumentation, digital imaging products and software, aerospace and defense electronics, and engineered systems. Our customers include government agencies, aerospace prime contractors, energy exploration and production companies, major industrial companies and airlines.
	In the second quarter of 2013, the Company changed the reporting structure of two of its interconnect business units. The two interconnect business units were formerly reported as part of the Aerospace and Defense Electronics segment and are now reported as part of the Instrumentation segment. These business units primarily serve energy production markets and are now managed by and integrated with our other interconnect businesses within Teledyne Oil & Gas, which is part of the marine instrumentation product line. Previously reported segment data has been restated to reflect this change. Total sales for the two business units transferred to the Instrumentation segment from the Aerospace and Defense Electronics segment were $55.3 million for fiscal year 2012.
	The Company has four reportable segments: Instrumentation; Digital Imaging; Aerospace and Defense Electronics; and Engineered Systems. The Company manages, evaluates and aggregates its operating segments for segment reporting purposes primarily on the basis of product and service type, production process, distribution methods, type of customer, management organization, sales growth potential and long-term profitability. The Instrumentation segment provides monitoring and control equipment for marine, environmental, scientific, industrial and defense applications, electronic test and measurement instruments and harsh environment interconnect products. The Digital Imaging segment includes high performance sensors, cameras and systems, within the visible, infrared and X-ray spectra, for use in industrial, government and medical applications, as well as MEMS. It also includes our sponsored and centralized research laboratories benefiting government programs and businesses. The Aerospace and Defense Electronics segment provides sophisticated electronic components and subsystems and communications products, including defense electronics, harsh environment interconnects, data acquisition and communications equipment for aircraft and components and subsystems for wireless and satellite communications, as well as general aviation batteries. The Engineered Systems segment provides innovative systems engineering and integration, advanced technology application, software development and manufacturing solutions for defense, space, environmental and energy applications. The Engineered Systems segment also designs and manufactures electrochemical energy systems and small turbine engines.
	Segment operating profit includes other income and expense directly related to the segment, but excludes noncontrolling interest, interest income and expense, gains and losses on the disposition of assets, sublease rental income and non-revenue licensing and royalty income, domestic and foreign income taxes and corporate office expenses.
	The third quarter and first nine months of 2013 reflected pretax charges totaling $14.3 million and $18.7 million, respectively, for severance and facility consolidation expense and environmental reserves. For the third quarter of 2013 the charges impacted each business segment as follows: Aerospace and Defense Electronics, $8.7 million; Engineered Systems, $2.7 million; Digital Imaging, $1.9 million; and Instrumentation, $1.0 million. The first nine months of 2013 the charges impacted each business segment as follows: Aerospace and Defense Electronics, $12.2 million; Engineered Systems, $2.9 million; Digital Imaging, $2.3 million; and Instrumentation, $1.3 million.
	The following table presents Teledyne’s interim industry segment disclosures for net sales and operating profit including other segment income. The table also provides a reconciliation of segment operating profit to total net income attributable to Teledyne (dollars in millions):

	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 30, 2012 (“2012 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 September 29, 2013 and the consolidated results of operations, consolidated comprehensive income third quarter and nine months then ended and consolidated cash flows for the nine months then ended. The results of operations and cash flows for the period ended September 29, 2013 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	'
	Recent Accounting Pronouncements
	Effective December 31, 2012, the Company adopted accounting guidance on the testing of indefinite-lived intangible assets for impairment. The guidance allows entities to first perform a qualitative assessment to determine the likelihood of an impairment for an indefinite-lived intangible asset and whether it is necessary to perform the quantitative impairment assessment currently required. The Company’s adoption of this guidance did not have any impact on Teledyne's financial position, results of operations or cash flows.
	Effective December 31, 2012, the Company adopted accounting guidance which updates the presentation of reclassifications from comprehensive income to net income in consolidated financial statements. Under this guidance, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income (“AOCI”) either by the respective line items of net income or by cross-reference to other required disclosures. The guidance does not change the requirements for reporting net income or other comprehensive income in financial statements. As the guidance relates to presentation only, the adoption did not have any impact on Teledyne's financial position, results of operations or cash flows.
