Summary of Significant Accounting Policies Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 30, 2012

The consolidated financial statements include the accounts of Teledyne and all wholly-owned and majority-owned domestic and foreign subsidiaries. Intercompany accounts and transactions have been eliminated.

Fiscal Year

The Company operates on a 52- or 53-week fiscal year convention ending on the Sunday nearest to December 31. Fiscal year 2012 was a 52-week fiscal year and ended on December 30, 2012. Fiscal year 2011 was a 52-week fiscal year and ended on January 1, 2012. Fiscal year 2010 was a 52-week fiscal year and ended on January 2, 2011. References to the years 2012, 2011 and 2010 are intended to refer to the respective fiscal year unless otherwise noted.

Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to product returns and replacements, allowance for doubtful accounts, inventories, intangible assets, income taxes, warranty obligations, pension and other postretirement benefits, long-term contracts, environmental, workers' compensation and general liability, employee dental and medical benefits and other contingencies and litigation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances at the time, the results of which form the basis for making its judgments. Actual results may differ materially from these estimates under different assumptions or conditions. Management believes that the estimates are reasonable.

Revenue Recognition

Commercial sales and revenue from U.S. Government fixed-price type contracts generally are recorded as shipments are made, as services are rendered or in some cases, on a percentage-of-completion basis. Sales under cost-reimbursement contracts are recorded as work is performed. Occasionally, for certain fixed-price type contracts that require substantial performance over a long time period (generally one or more years), revenues are recorded under the percentage-of-completion (“POC”) method. Teledyne measures the extent of progress toward completion using the units-of-delivery method, cost-to-cost method or based upon attainment of scheduled performance milestones which could be time, event or expense driven. Occasionally, invoices are submitted to be paid by the customer under a contractual agreement which has a different time schedule than the related revenue recognition. Since certain contracts extend over a long period of time, all revisions in cost and revenue estimates during the progress of work have the effect of adjusting the current period earnings on a cumulative catch-up basis. If the current contract estimate indicates a loss, provision is made for the total anticipated loss in the period that it becomes evident. Sales under cost-reimbursement contracts are recorded as allowable costs are incurred and fees are earned. For revenues recorded on contracts that require the Company to warehouse certain goods, all risks of loss is borne by the customer. Changes in estimates related to contracts accounted for under the POC method are recorded using the cumulative catch-up method of accounting.

Shipping and Handling

Shipping and handling fees charged to customers are classified as revenue while shipping and handling costs retained by Teledyne are classified as cost of sales in the accompanying consolidated statements of income.

Product Warranty and Replacement Costs

Some of the Company's products are subject to specified warranties and the Company reserves for the estimated cost of product warranties on a product-specific basis. Facts and circumstances related to a product warranty matter and cost estimates to return, repair and/or replace the product are considered when establishing a product warranty reserve. The adequacy of the preexisting 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 accrued liabilities and long-term liabilities on the balance sheet.

Research and Development

Selling, general and administrative expenses include company-funded research and development and bid and proposal costs which are expensed as incurred and were $131.6 million in 2012, $101.9 million in 2011, and $61.3 million in 2010. Costs related to customer-funded research and development contracts were $232.6 million in 2012, $213.8 million in 2011 and $258.6 million in 2010 and are charged to cost of sales as the related sales are recorded. A portion of the costs incurred for company-funded research and development is recoverable through overhead cost allocations on government contracts.

Income Taxes

Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amount in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, we begin with historical results adjusted for the results of discontinued operations and incorporate assumptions about the amount of future state, federal and foreign pretax operating income adjusted for items that do not have tax consequences. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, we consider three years of cumulative operating income. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized.

Income tax positions must meet a more-likely-than-not recognition in order to be recognized in the financial statements. We recognize potential accrued interest and penalties related to unrecognized tax benefits within operations as income tax expense. As new information becomes available, the assessment of the recognition threshold and the measurement of the associated tax benefit of uncertain tax positions may result in financial statement recognition or derecognition.

Net Income Per Common 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.

Accounts Receivable

Receivables are presented net of a reserve for doubtful accounts of $4.7 million at December 30, 2012, and $3.8 million at January 1, 2012. Expense recorded for the reserve for doubtful accounts was $1.4 million, $0.7 million, and $1.4 million for 2012, 2011, and 2010, respectively. An allowance for doubtful accounts is established for losses expected to be incurred on accounts receivable balances. Judgment is required in the estimation of the allowance and is based upon specific identification, collection history and creditworthiness of the debtor. The Company markets its products and services principally throughout the United States, Europe, Japan and Canada to commercial customers and agencies of, and prime contractors to, the U.S. Government. Trade credit is extended based upon evaluations of each customer's ability to perform its obligations, which are updated periodically.

Cash Equivalents

Cash equivalents consist of highly liquid money-market mutual funds and bank deposits with maturities of three months or less when purchased.

Inventories

Inventories are stated at the lower of cost or market, less progress payments. The majority of inventory values are principally valued on an average cost, or first-in, first-out method, while the remainder are stated at cost based on the last-in, first-out method. Costs include direct material, direct labor, applicable manufacturing and engineering overhead, and other direct costs.

Property, Plant and Equipment

Property, plant and equipment is capitalized at cost. Property, plant and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are determined using a combination of accelerated and straight-line methods over the estimated useful lives of the various asset classes. Buildings and building improvements are depreciated over periods not exceeding 45 years, equipment over 5 to 18 years, computer hardware and software over 3 to 5 years and leasehold improvements over the shorter of the estimated remaining lives or lease terms. Significant improvements are capitalized while maintenance and repairs are charged to expense as incurred.

Goodwill and Other Intangible Assets

The Company performs an annual impairment test for goodwill and other intangible assets in the fourth quarter of each year, or more often as circumstances require. The two-step impairment test is used to first identify potential goodwill impairment and then measure the amount of goodwill impairment loss, if any. When it is determined that an impairment has occurred, an appropriate charge to operations is recorded. Based on the annual impairment test completed in the fourth quarter of 2012, no impairment of goodwill or intangible assets was indicated.

Business acquisitions are accounted for under the purchase method by assigning the purchase price to tangible and intangible assets acquired and liabilities assumed. Assets acquired and liabilities assumed are recorded at their fair values and the excess of the purchase price over the amounts assigned is recorded as goodwill. Purchased intangible assets with finite lives are amortized over their estimated useful lives. Goodwill and intangible assets with indefinite lives are not amortized, but tested at least annually for impairment.

Other Long-Lived Assets

The carrying value of long-lived assets is periodically evaluated in relation to the operating performance and sum of undiscounted future cash flows of the underlying businesses. An impairment loss is recognized when the sum of expected undiscounted future net cash flows is less than book value.

Environmental

Costs that mitigate or prevent future environmental contamination or extend the life, increase the capacity or improve the safety or efficiency of property utilized in current operations are capitalized. Other costs that relate to current operations or an existing condition caused by past operations are expensed. Environmental liabilities are recorded when the Company's liability is probable and the costs are reasonably estimable, but generally not later than the completion of the feasibility study or the Company's recommendation of a remedy or commitment to an appropriate plan of action. The accruals are reviewed periodically and, as investigations and remediations proceed, adjustments are made as necessary. Accruals for losses from environmental remediation obligations do not consider the effects of inflation, and anticipated expenditures are not discounted to their present value. The accruals are not reduced by possible recoveries from insurance carriers or other third parties, but do reflect anticipated allocations among potentially responsible parties at federal Superfund sites or similar state-managed sites and an assessment of the likelihood that such parties will fulfill their obligations at such sites. The measurement of environmental liabilities by the Company is based on currently available facts, present laws and regulations, and current technology. Such estimates take into consideration the Company's prior experience in site investigation and remediation, the data concerning cleanup costs available from other companies and regulatory authorities, and the professional judgment of the Company's environmental personnel in consultation with outside environmental specialists, when necessary.

Foreign Currency Translation

The Company's foreign entities' accounts are generally measured using local currency as the functional currency. Assets and liabilities of these entities are translated at the exchange rate in effect at year-end. Revenues and expenses are translated at average month end rates of exchange prevailing during the year. Unrealized translation gains and losses arising from differences in exchange rates from period to period are included as a component of accumulated other comprehensive loss in stockholders' equity. A majority of the Company's sales are denominated in U.S. dollars which mitigates the effect of exchange rate changes.

Hedging Activities/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 objective is to protect the United States dollar value of future cash flows and minimize the volatility of reported earnings. Due to the February 2011 acquisition of DALSA, the Company began to utilize 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.

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 accumulated other comprehensive income in stockholders' equity until the underlying hedged item is reflected in our consolidated statements of income, at which time the effective amount in accumulated other comprehensive income is reclassified to cost of sales in our consolidated statements of income. The Company expects to reclassify a gain of approximately $0.5 million over the next 12 months based on the year end 2012 exchange rate.

In the event that the gains or losses in accumulated other comprehensive income ("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 December 30, 2012, Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $51.7 million and these contracts had a fair value of $0.8 million. These foreign currency forward contracts have maturities ranging from March 2013 to February 2014.

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 December 30, 2012, 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$	2.6	Euros	€	(2.0	)
Canadian Dollars	C$	26.3	U.S. Dollars	$	(26.3	)
Great Britain Pounds	£	5.5	U.S. Dollars	$	(8.9	)
U.S. Dollars	$	8.9	Euros	€	(6.8	)
U.S. Dollars	$	2.6	Japanese Yen	¥	(218.0	)
U.S. Dollars	$	1.0	Korean Won	₩	(1,126.0	)

The gains and losses on these derivatives which are not designated as hedging instruments under ASC 815, Derivatives and Hedging (“ASC 815”), are intended to, at a minimum, partially offset the transaction gains and losses recognized in earnings. Under ASC 815, 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 fiscal year 2012 and 2011 was as follows (in millions):



	2012			2011
Net gain (loss) recognized in AOCI (a)	$	2.0		$	(2.4	)
Net loss reclassified from AOCI into cost of sales (a)	$	(0.9	)	$	(0.1	)
Net foreign exchange gain recognized in other income and expense (b)	$	0.5		$	0.5

(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 fiscal year 2012 and 2011 was a loss of $0.1 million and $0.7 million of income, respectively.

The fair val

Fair Value Measurements

When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. The Company uses the following three levels of inputs in determining the fair value of the Company's assets and liabilities, focusing on the most observable inputs when available:


•	Level 1-Quoted prices in active markets for identical assets or liabilities.

•

Level 2-Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.


•	Level 3-Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is disclosed is determined based on the lowest level input that is significant to the fair value measurement.

Recent Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board ("FASB") issued new 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. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The Company does not expect the adoption of this guidance to have a material impact on Teledyne's financial position, results of operations or cash flows.

In 2011, the FASB issued new disclosure guidance related to the presentation of the Statement of Comprehensive Income. The new disclosure guidance requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Teledyne adopted the new presentation requirement effective January 2, 2012. Teledyne elected the two-statement approach presenting other comprehensive income in a separate statement immediately following the condensed consolidated statements of income.

In 2011, the FASB issued new accounting guidance that amends some fair value measurement principles and disclosure requirements. The new guidance provides a consistent definition and measurement of fair value, as well as similar disclosure requirements between U.S. GAAP and International Financial Reporting Standards. It also changes certain fair value measurement principles, clarifies the application of existing fair value measurement and expands the disclosure requirements, particularly for Level 3 fair value measurements. Teledyne's adoption of these new provisions, effective January 2, 2012, did not have an impact on our financial position or results of operations.
