| Summary of Significant Accounting Policies |
Basis of Presentation Our fiscal years are based on a 52- or 53-week period ending on the last Saturday in December. The condensed consolidated balance sheet at December 29, 2012 has been derived from our audited financial statements at that date. The interim condensed consolidated financial statements as of March 30, 2013 (also referred to as “the first quarter of fiscal 2013” and “the first three months of fiscal 2013”) and March 31, 2012 (also referred to as “the first quarter of fiscal 2012” and “the first three months of fiscal 2012”) are unaudited. However, in management’s opinion, these financial statements reflect all adjustments (consisting only of normal, recurring items) necessary to provide a fair presentation of our financial position, results of operations and cash flows for the periods presented. The first quarter of fiscal 2013 and 2012 were each comprised of 13 weeks. Our interim results are not necessarily indicative of the results that should be expected for the full year. For a better understanding of Cohu, Inc. and our financial statements, we recommend reading these interim condensed consolidated financial statements in conjunction with our audited financial statements for the year ended December 29, 2012, which are included in our 2012 Annual Report on Form 10-K, filed with the U. S. Securities and Exchange Commission (“SEC”). In the following notes to our interim condensed consolidated financial statements, Cohu, Inc. is referred to as “Cohu”, “we”, “our” and “us”. Risks and Uncertainties We are subject to a number of risks and uncertainties that may significantly impact our future operating results. These risks and uncertainties are discussed under Item 1A. “Risk Factors” included in this Form 10-Q. Understanding these risks and uncertainties is integral to the review of our interim condensed consolidated financial statements. Concentration of Credit Risk Financial instruments that potentially subject us to significant credit risk consist principally of cash equivalents, short-term investments and trade accounts receivable. We invest in a variety of financial instruments and, by policy, limit the amount of credit exposure with any one issuer. Trade accounts receivable are presented net of allowance for doubtful accounts of $0.6 million and $0.3 million at March 30, 2013 and December 29, 2012, respectively. Our customers include semiconductor manufacturers and semiconductor test subcontractors and other customers located throughout many areas of the world. While we believe that our allowance for doubtful accounts is adequate and represents our best estimate at March 30, 2013, we will continue to monitor customer liquidity and other economic conditions, which may result in changes to our estimates regarding collectability. Goodwill, Other Intangible Assets and Long-lived Assets We evaluate goodwill for impairment annually and when an event occurs or circumstances change that indicate that the carrying value may not be recoverable. We test goodwill for impairment by first comparing the book value of net assets to the fair value of the reporting units. If the fair value is determined to be less than the book value, a second step is performed to compute the amount of impairment as the difference between the estimated fair value of goodwill and the carrying value. We estimated the fair values of our reporting units primarily using the income approach valuation methodology that includes the discounted cash flow method, taking into consideration the market approach and certain market multiples as a validation of the values derived using the discounted cash flow methodology. Forecasts of future cash flows are based on our best estimate of future net sales and operating expenses, based primarily on customer forecasts, industry trade organization data and general economic conditions. We conduct our annual impairment test as of October 1 of each year. Other events and changes in circumstances may also require goodwill to be tested for impairment between annual measurement dates. While a decline in stock price and market capitalization is not specifically cited as a goodwill impairment indicator, a company’s stock price and market capitalization should be considered in determining whether it is more likely than not that the fair value of a reporting unit is less that its carrying value. Additionally, a significant decline in a company’s stock price may suggest that an adverse change in the business climate may have caused the fair value of one or more reporting units to fall below their carrying value. The financial and credit market volatility directly impacts our fair value measurement through our stock price that we use to determine our market capitalization. During times of volatility, significant judgment must be applied to determine whether credit or stock price changes are a short-term swing or a longer-term trend. As of March 30, 2013 we do not believe there have been any events or circumstances that would require us to perform an interim goodwill impairment review, however, a sustained decline in Cohu’s market capitalization below its book value could lead us to determine, in a future period, that an interim goodwill impairment review is required and may result in an impairment charge which would have a negative impact on our results of operations.
Long-lived assets, other than goodwill, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used, or any other significant adverse change that would indicate that the carrying amount of an asset or group of assets may not be recoverable. For long-lived assets, impairment losses are only recorded if the asset’s carrying amount is not recoverable through its undiscounted, probability-weighted future cash flows. We measure the impairment loss based on the difference between the carrying amount and estimated fair value. Share-Based Compensation Share-based compensation expense related to stock options is recorded based on the fair value of the award on its grant date which we estimate using the Black-Scholes valuation model. Share-based compensation expense related to restricted stock unit awards is calculated based on the market price of our common stock on the grant date, reduced by the present value of dividends expected to be paid on our common stock prior to vesting of the restricted stock unit. Reported share-based compensation is classified, in the condensed consolidated interim financial statements, as follows (in thousands):
Income (Loss) Per Share Basic income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the reporting period. Diluted income per share includes the dilutive effect of common shares potentially issuable upon the exercise of stock options, vesting of outstanding restricted stock units and issuance of stock under our employee stock purchase plan using the treasury stock method. In loss periods, potentially dilutive securities are excluded from the per share computations due to their anti-dilutive effect. For purposes of computing diluted income per share, stock options with exercise prices that exceed the average fair market value of our common stock for the period are excluded. The following table reconciles the denominators used in computing basic and diluted income (loss) per share (in thousands):
Revenue Recognition Our revenue recognition policy is disclosed in Note 1 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 29, 2012. As more fully described in that policy, revenue from products that have not previously satisfied customer acceptance requirements is recognized upon customer acceptance. The gross profit on sales that are not recognized is generally recorded as deferred profit and reflected as a current liability in our consolidated balance sheet. At March 30, 2013, we had deferred revenue totaling approximately $6.7 million and deferred profit of $5.6 million. At December 29, 2012 , we had deferred revenue totaling approximately $3.6 million and deferred profit of $2.1 million. Comprehensive Income (Loss) Our accumulated other comprehensive income (loss) balance totaled approximately $(2.2) million and $1.8 million at March 30, 2013 and December 29, 2012, respectively, and was attributed to all non-owner changes in stockholders’ equity and consists of, on an after-tax basis where applicable, foreign currency adjustments resulting from the translation of certain accounts into U.S. dollars where the functional currency is the Euro or the Swiss Franc, unrealized gains and losses on investments and adjustments related to postretirement benefits. Reclassification adjustments from accumulated other comprehensive income during the first three months of fiscal 2013 and 2012 were not significant. Retiree Medical Benefits We provide post-retirement health benefits to certain executives and directors under a noncontributory plan. The net periodic benefit cost incurred during the first three months of fiscal 2013 and 2012 was not significant. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements - In July 2012, the Financial Accounting Standards Board (“FASB”) issued guidance to simplify the testing for a drop in value of intangible assets such as trademarks, patents, and distribution rights. The amended standard reduces the cost of accounting for indefinite-lived intangible assets, especially in cases where the likelihood of impairment is low. The changes permit businesses and other organizations to first use subjective criteria to determine if an intangible asset has lost value. The amendments will be effective for fiscal years starting after September 15, 2012 with early adoption permitted. The adoption of this new guidance in the first quarter of fiscal 2013 did not have a material impact on our consolidated financial position, results of operations or cash flows. In February 2013, FASB issued authoritative guidance that will require a public entity to present in its annual and interim financial statements information about reclassification adjustments from accumulated other comprehensive income in a single note or on the face of the financial statements. The adoption of this new guidance in the first quarter of fiscal 2013 did not have a material impact on our consolidated financial position, results of operations or cash flows. Recently Issued Accounting Pronouncements - In March 2013, the FASB issued guidance on a parent company’s accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. The new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The amendments will be effective for fiscal years and interim periods starting after December 15, 2013 with early adoption permitted. We do not believe our adoption of the new guidance in the first quarter of fiscal 2014 will have an impact on our consolidated financial position, results of operations or cash flows. |

| Strategic Technology Transactions, Goodwill and Other Purchased Intangible Assets |
Ismeca On December 31, 2012, we acquired all of the outstanding share capital of Ismeca Semiconductor Holding SA (“Ismeca”). Ismeca, headquartered in La Chaux-de-Fonds, Switzerland, and with major operations in Malacca, Malaysia and Suzhou, China, designs, manufactures and sells turret-based test handling and back-end finishing equipment for integrated circuits, light emitting diodes (LEDs) and discrete components. The acquisition has been accounted for in conformity with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 805, Business Combinations (“ASC 805”). The preliminary purchase price of this acquisition was approximately $84.9 million, and was funded primarily by cash reserves ($57.1 million) and certain liabilities assumed ($27.7 million). Total consideration has been allocated to the assets acquired and liabilities assumed based on their estimated respective fair values as of the completion of the acquisition. The acquisition of Ismeca resulted in the recognition of a preliminary estimate of goodwill of approximately $19.1 million and has been assigned to our semiconductor equipment segment. Amounts allocated to intangible assets are being amortized on a straight-line basis over their useful lives of eight years.
The table below represents a preliminary allocation of purchase price based on management’s internal evaluation to estimate their respective fair values (in thousands):
The preliminary allocation of the other intangible assets is as follows (in thousands):
The preliminary value assigned to Ismeca’s unpatented complete technology was determined by discounting the estimated future cash flows associated with the existing developed and core technologies to their present value. Developed and core technology, which comprise products that have reached technological feasibility, includes the products in Ismeca’s product line. The revenue estimates used to value the unpatented complete technology were based on estimates of relevant market sizes and growth factors, expected trends in technology and the nature and expected timing of new product introductions by Ismeca and its competitors. The rates utilized to discount the net cash flows of unpatented complete technology to their present value are based on the risks associated with the respective cash flows taking into consideration the weighted average cost of capital of Cohu’s semiconductor equipment segment. The preliminary value assigned to Ismeca’s customer relationships was determined by discounting the estimated cash flows associated with the existing customers as of the acquisition date taking into consideration expected attrition of the existing customer base. The estimated cash flows were based on revenues for those existing customers net of operating expenses and net contributory asset charges associated with servicing those customers. The estimated revenues were based on revenue growth rates for the back-end semiconductor equipment industry. Operating expenses were estimated based on the supporting infrastructure expected to sustain the assumed revenue growth rates. Net contributory asset charges were based on the estimated fair value of those assets that contribute to the generation of the estimated cash flows. The primary areas of the purchase price allocation that have not been finalized relate to a pre-acquisition contingency related to contractual obligations to purchase inventory from suppliers, certain tax issues, purchased intangible assets and residual goodwill. Upon completion of the fair value assessment, Cohu anticipates that the ultimate purchase price allocation may differ from the preliminary assessment outlined above. Any changes to the initial estimates of the fair value of the assets and liabilities will be allocated primarily to intangible assets and related deferred taxes or residual goodwill.
Duma In August 2012, our microwave communication equipment segment acquired the intellectual property and certain other assets of Duma Video, Inc. (“Duma”), a distributor of low latency compression video encoding and decoding devices. The purchase price of these assets was approximately $1.0 million and the amount allocated to intangible assets is being amortized on a straight-line basis over three years. Under the terms of the purchase agreement, in addition to the up-front cash payment, we will be required to make future payments to the seller totaling a maximum of approximately $0.5 million, contingent upon the completion of certain milestone events. Goodwill Changes in the carrying value of goodwill by reportable segment during the year ended December 29, 2012 and the three-month period ended March 30, 2013 were as follows (in thousands):
Purchased Intangible Assets Purchased intangible assets, subject to amortization are as follows (in thousands):
Amortization expense related to intangible assets in the first quarter of fiscal 2013 and 2012 was approximately $1.7 million and $1.0 million, respectively. The amounts included in the table above for the period ended March 30, 2013 exclude approximately $2.2 million and $4.7 million, related to the trade names of Rasco and Ismeca, respectively, and for the period ended December 29, 2012 exclude approximately $2.3 million related to Rasco trade name which have indefinite life and are not being amortized. Changes in the carrying values of these intangible assets are a result of the impact of fluctuations in currency exchange rates. |

| Financial Instruments Measured at Fair Value |
Our financial instruments measured at fair value consisted primarily of cash, corporate debt securities, government and government agency securities, state and municipal securities, money market funds, other investment grade securities, forward exchange contracts and structured option transactions. We do not hold investment securities for trading purposes. All short-term investments are classified as available-for-sale and recorded at fair value. Investment securities are exposed to market risk due to changes in interest rates and credit risk and we monitor credit risk and attempt to mitigate exposure by making high-quality investments and through investment diversification. Gains and losses on investments are calculated using the specific-identification method and are recognized during the period in which the investment is sold or when an investment experiences an other-than-temporary decline in value. Factors that could indicate an impairment exists include, but are not limited to: earnings performance, changes in credit rating or adverse changes in the regulatory or economic environment of the asset. Gross realized gains and losses on sales of short-term investments are included in interest income. Realized gains and losses for the periods presented were not significant.
Investments that we have classified as short-term, by security type, are as follows (in thousands):
Effective maturities of short-term investments at March 30, 2013 and December 29, 2012, were as follows (in thousands):
Our municipal securities include variable rate demand notes which can be put (sold at par) typically on a daily basis with settlement periods ranging from the same day to one week and have varying contractual maturities through 2037. These securities can be used for short-term liquidity needs and are held for limited periods of time. At March 30, 2013 and December 29, 2012 these securities had amortized cost and fair value of $1.4 million and $1.5 million, respectively, and are included in “Due in one year or less” in the table above. Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. When available, we use quoted market prices to determine the fair value of our investments, and they are included in Level 1. When quoted market prices are unobservable, we use quotes from independent pricing vendors based on recent trading activity and other relevant information, and they are included in Level 2.
The following table summarizes, by major security type, our assets that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy (in thousands):
In connection with our purchase of Ismeca on December 31, 2012, we acquired forward exchange contracts and currency option contracts which are used to hedge forecasted foreign currency balances and to mitigate the effect of exchange rate fluctuations of the Swiss Franc. The maturity of the option contracts range from one week to eight months. We do not use these instruments for trading or speculative purposes and have determined these contracts fall within Level 2 of the fair value hierarchy. During the three months ended March 30, 2013, there were no transfers between Level 1 and Level 2 or into or out of Level 3 related to these instruments. We have recorded these derivative instruments on the balance sheet at their fair value with all realized and unrealized losses recognized in the statement of operations. For the three-month period ended March 30, 2013, total losses were approximately $0.4 million. |

| Employee Stock Benefit Plans |
Employee Stock Purchase Plan The Cohu, Inc. 1997 Employee Stock Purchase Plan (“the Plan”) provides for the issuance of shares of our common stock. Under the Plan, eligible employees may purchase shares of Cohu common stock through payroll deductions at a price equal to 85 percent of the lower of the fair market value of Cohu common stock at the beginning or end of each 6-month purchase period, subject to certain limits. No shares were issued under the Plan during the three-month period ended March 30, 2013 and there were 485,542 shares available for future issuance. Stock Options Under our equity incentive plans, stock options may be granted to employees, consultants and directors to purchase a fixed number of shares of our common stock. The exercise prices of options granted are at least equal to the fair market value of our common stock on the dates of grant. Options generally vest and become exercisable after one year or in four annual increments beginning one year after the grant date and expire ten years from the grant date. At March 30, 2013, there were 1,000,825 shares available for future equity grants under the 2005 Equity Plan. We have historically issued new shares of our common stock upon share option exercise. Subsequent to December 29, 2012, we awarded stock options covering 445,346 shares of our common stock to employees and at March 30, 2013, we had 3,435,701 stock options outstanding. These options had a weighted-average exercise price of $12.21 per share, an aggregate intrinsic value of approximately $1.8 million and the weighted average remaining contractual term was approximately 5.8 years.
At March 30, 2013, we had 2,454,448 stock options outstanding that were exercisable. These options had a weighted-average exercise price of $12.76 per share, an aggregate intrinsic value of $1.8 million and the weighted average remaining contractual term was approximately 4.4 years. Restricted Stock Units We issue restricted stock units to certain employees, consultants and directors. Restricted stock units vest over either a one-year or a four-year period from the date of grant. Prior to vesting, restricted stock units do not have dividend equivalent rights, do not have voting rights and the shares underlying the restricted stock units are not considered issued and outstanding. Shares of our common stock will be issued on the date the restricted stock units vest. Subsequent to December 29, 2012, we awarded restricted stock units covering 474,313 shares of our common stock to employees and at March 30, 2013, we had 991,267 restricted stock units outstanding with an aggregate intrinsic value of approximately $9.3 million and the weighted average remaining vesting period was approximately 2.0 years. Equity-Based Performance Stock Units We issue equity-based performance stock units to certain employees to reward achievement of financial performance goals set by the Board of Directors. Equity -based performance stock units vest over a three-year period from the date of grant. Prior to vesting, equity-based performance stock units do not have dividend equivalent rights, do not have voting rights and the shares underlying the restricted stock units are not considered issued and outstanding. The number of shares of stock ultimately issued to participants will depend upon the extent to which goals are met. The award measurement period is one fiscal year. Based upon the level of goal achievement, the number of shares we will issue can range from 0% up to 150% of the granted units. These outstanding units will vest over three years from the date of initial grant and upon final Board of Directors approval, shares of our common stock will be considered issued as of that date. In March 2013, we granted equity-based performance units covering 140,865 shares of our common stock to certain employees. In March 2012, we granted equity-based performance units covering 128,916 shares of our common stock to certain employees and upon completion of the award measurement period 77,455 units were issued shares based on the financial goals achieved during fiscal 2012. |

| Income Tax Disclosure [Abstract] | |||
| Income Taxes |
Ordinarily, interim tax provisions are calculated using the estimated effective tax rate (“ETR”) expected to be applicable for the full fiscal year. However, when a reliable estimate of the annual ETR cannot be made, the actual ETR for the year-to-date period may be the best estimate of the annual ETR. For the three months ended March 30, 2013 we used the actual year-to-date ETR in computing our tax benefit as a reliable estimate of the annual ETR cannot be made as relatively small changes in our projected income or loss produce a significant variance in our ETR. The ETR for the three months ended March 30, 2013 and March 31, 2012, was 6.3% and 10.8%, respectively. The tax benefit in 2013 and 2012 differs from the U.S. federal statutory rate primarily due to the inability to benefit our domestic losses, foreign income taxed at lower rates, changes in our deferred tax asset valuation allowance, state taxes and changes and interest related to unrecognized tax benefits. There was no material change to our unrecognized tax benefits and interest accrued related to unrecognized tax benefits during the three months ended March 30, 2013. |

| Industry Segments |
Our reportable segments are business units that offer different products and are managed separately because each business requires different technology and marketing strategies. Our reportable segments are: semiconductor equipment, microwave communications and video cameras. As discussed in Note 2, on December 31, 2012 we purchased Ismeca, which is included in our semiconductor equipment segment. We allocate resources and evaluate the performance of segments based on profit or loss from operations, excluding interest, corporate expenses and unusual gains or losses. Intersegment sales were not significant for any period.
Financial information by industry segment is as follows (in thousands):
A small number of customers historically have been responsible for a significant portion of our consolidated net sales. During the first quarter of fiscal 2013, one customer of the semiconductor equipment segment represented more than 10% of consolidated net sales and accounted for 20% of our total consolidated net sales. During the first quarter of fiscal 2012, two customers of the semiconductor equipment segment each represented more than 10% of consolidated net sales and, combined, they accounted for 59% of our total consolidated net sales. |

| Basis of Presentation | Basis of Presentation Our fiscal years are based on a 52- or 53-week period ending on the last Saturday in December. The condensed consolidated balance sheet at December 29, 2012 has been derived from our audited financial statements at that date. The interim condensed consolidated financial statements as of March 30, 2013 (also referred to as “the first quarter of fiscal 2013” and “the first three months of fiscal 2013”) and March 31, 2012 (also referred to as “the first quarter of fiscal 2012” and “the first three months of fiscal 2012”) are unaudited. However, in management’s opinion, these financial statements reflect all adjustments (consisting only of normal, recurring items) necessary to provide a fair presentation of our financial position, results of operations and cash flows for the periods presented. The first quarter of fiscal 2013 and 2012 were each comprised of 13 weeks. Our interim results are not necessarily indicative of the results that should be expected for the full year. For a better understanding of Cohu, Inc. and our financial statements, we recommend reading these interim condensed consolidated financial statements in conjunction with our audited financial statements for the year ended December 29, 2012, which are included in our 2012 Annual Report on Form 10-K, filed with the U. S. Securities and Exchange Commission (“SEC”). In the following notes to our interim condensed consolidated financial statements, Cohu, Inc. is referred to as “Cohu”, “we”, “our” and “us”. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risks and Uncertainties | Risks and Uncertainties We are subject to a number of risks and uncertainties that may significantly impact our future operating results. These risks and uncertainties are discussed under Item 1A. “Risk Factors” included in this Form 10-Q. Understanding these risks and uncertainties is integral to the review of our interim condensed consolidated financial statements. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject us to significant credit risk consist principally of cash equivalents, short-term investments and trade accounts receivable. We invest in a variety of financial instruments and, by policy, limit the amount of credit exposure with any one issuer. Trade accounts receivable are presented net of allowance for doubtful accounts of $0.6 million and $0.3 million at March 30, 2013 and December 29, 2012, respectively. Our customers include semiconductor manufacturers and semiconductor test subcontractors and other customers located throughout many areas of the world. While we believe that our allowance for doubtful accounts is adequate and represents our best estimate at March 30, 2013, we will continue to monitor customer liquidity and other economic conditions, which may result in changes to our estimates regarding collectability. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Goodwill, Other Intangible Assets and Long-lived Assets | Goodwill, Other Intangible Assets and Long-lived Assets We evaluate goodwill for impairment annually and when an event occurs or circumstances change that indicate that the carrying value may not be recoverable. We test goodwill for impairment by first comparing the book value of net assets to the fair value of the reporting units. If the fair value is determined to be less than the book value, a second step is performed to compute the amount of impairment as the difference between the estimated fair value of goodwill and the carrying value. We estimated the fair values of our reporting units primarily using the income approach valuation methodology that includes the discounted cash flow method, taking into consideration the market approach and certain market multiples as a validation of the values derived using the discounted cash flow methodology. Forecasts of future cash flows are based on our best estimate of future net sales and operating expenses, based primarily on customer forecasts, industry trade organization data and general economic conditions. We conduct our annual impairment test as of October 1 of each year. Other events and changes in circumstances may also require goodwill to be tested for impairment between annual measurement dates. While a decline in stock price and market capitalization is not specifically cited as a goodwill impairment indicator, a company’s stock price and market capitalization should be considered in determining whether it is more likely than not that the fair value of a reporting unit is less that its carrying value. Additionally, a significant decline in a company’s stock price may suggest that an adverse change in the business climate may have caused the fair value of one or more reporting units to fall below their carrying value. The financial and credit market volatility directly impacts our fair value measurement through our stock price that we use to determine our market capitalization. During times of volatility, significant judgment must be applied to determine whether credit or stock price changes are a short-term swing or a longer-term trend. As of March 30, 2013 we do not believe there have been any events or circumstances that would require us to perform an interim goodwill impairment review, however, a sustained decline in Cohu’s market capitalization below its book value could lead us to determine, in a future period, that an interim goodwill impairment review is required and may result in an impairment charge which would have a negative impact on our results of operations.
Long-lived assets, other than goodwill, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used, or any other significant adverse change that would indicate that the carrying amount of an asset or group of assets may not be recoverable. For long-lived assets, impairment losses are only recorded if the asset’s carrying amount is not recoverable through its undiscounted, probability-weighted future cash flows. We measure the impairment loss based on the difference between the carrying amount and estimated fair value. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Share-Based Compensation | Share-Based Compensation Share-based compensation expense related to stock options is recorded based on the fair value of the award on its grant date which we estimate using the Black-Scholes valuation model. Share-based compensation expense related to restricted stock unit awards is calculated based on the market price of our common stock on the grant date, reduced by the present value of dividends expected to be paid on our common stock prior to vesting of the restricted stock unit. Reported share-based compensation is classified, in the condensed consolidated interim financial statements, as follows (in thousands):
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income (Loss) Per Share | Income (Loss) Per Share Basic income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the reporting period. Diluted income per share includes the dilutive effect of common shares potentially issuable upon the exercise of stock options, vesting of outstanding restricted stock units and issuance of stock under our employee stock purchase plan using the treasury stock method. In loss periods, potentially dilutive securities are excluded from the per share computations due to their anti-dilutive effect. For purposes of computing diluted income per share, stock options with exercise prices that exceed the average fair market value of our common stock for the period are excluded. The following table reconciles the denominators used in computing basic and diluted income (loss) per share (in thousands):
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition | Revenue Recognition Our revenue recognition policy is disclosed in Note 1 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 29, 2012. As more fully described in that policy, revenue from products that have not previously satisfied customer acceptance requirements is recognized upon customer acceptance. The gross profit on sales that are not recognized is generally recorded as deferred profit and reflected as a current liability in our consolidated balance sheet. At March 30, 2013, we had deferred revenue totaling approximately $6.7 million and deferred profit of $5.6 million. At December 29, 2012 , we had deferred revenue totaling approximately $3.6 million and deferred profit of $2.1 million. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Comprehensive Income (Loss) | Comprehensive Income (Loss) Our accumulated other comprehensive income (loss) balance totaled approximately $(2.2) million and $1.8 million at March 30, 2013 and December 29, 2012, respectively, and was attributed to all non-owner changes in stockholders’ equity and consists of, on an after-tax basis where applicable, foreign currency adjustments resulting from the translation of certain accounts into U.S. dollars where the functional currency is the Euro or the Swiss Franc, unrealized gains and losses on investments and adjustments related to postretirement benefits. Reclassification adjustments from accumulated other comprehensive income during the first three months of fiscal 2013 and 2012 were not significant. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Retiree Medical Benefits | Retiree Medical Benefits We provide post-retirement health benefits to certain executives and directors under a noncontributory plan. The net periodic benefit cost incurred during the first three months of fiscal 2013 and 2012 was not significant. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements - In July 2012, the Financial Accounting Standards Board (“FASB”) issued guidance to simplify the testing for a drop in value of intangible assets such as trademarks, patents, and distribution rights. The amended standard reduces the cost of accounting for indefinite-lived intangible assets, especially in cases where the likelihood of impairment is low. The changes permit businesses and other organizations to first use subjective criteria to determine if an intangible asset has lost value. The amendments will be effective for fiscal years starting after September 15, 2012 with early adoption permitted. The adoption of this new guidance in the first quarter of fiscal 2013 did not have a material impact on our consolidated financial position, results of operations or cash flows. In February 2013, FASB issued authoritative guidance that will require a public entity to present in its annual and interim financial statements information about reclassification adjustments from accumulated other comprehensive income in a single note or on the face of the financial statements. The adoption of this new guidance in the first quarter of fiscal 2013 did not have a material impact on our consolidated financial position, results of operations or cash flows. Recently Issued Accounting Pronouncements - In March 2013, the FASB issued guidance on a parent company’s accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. The new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The amendments will be effective for fiscal years and interim periods starting after December 15, 2013 with early adoption permitted. We do not believe our adoption of the new guidance in the first quarter of fiscal 2014 will have an impact on our consolidated financial position, results of operations or cash flows. |

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise.

An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.
