| Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 28, 2013 has been derived from our audited financial statements at that date. The interim condensed consolidated financial statements as of March 29, 2014 (also referred to as “the first quarter of fiscal 2014” and “the first three months of fiscal 2014”) and March 30, 2013 (also referred to as “the first quarter of fiscal 2013” and “the first three months of fiscal 2013”) 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 2014 and 2013 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 28, 2013, which are included in our 2013 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 $0.7 million and $0.6 million at March 29, 2014 and December 28, 2013, 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 29, 2014, 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 1st of each year, and have determined there is no impairment as of October 1, 2013 as we determined that the estimated fair values of our semiconductor equipment and microwave communications reporting units exceeded their carrying values by approximately 31% and 11%, respectively, on that date. 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 29, 2014 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 28, 2013. 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 29, 2014, we had deferred revenue totaling approximately $9.0 million and deferred profit of $6.3 million. At December 28, 2013, we had deferred revenue totaling approximately $7.4 million and deferred profit of $6.1 million. Comprehensive Income Our accumulated other comprehensive income balance totaled approximately $7.0 million and $6.7 million at March 29, 2014 and December 28, 2013, 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 to accumulated other comprehensive income during the first three months of fiscal 2014 and 2013 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 2014 and 2013 was not significant. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements – In July 2013, the Financial Accounting Standards Board (“FASB”) issued guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This amendment to previous income tax guidance clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax benefit is disallowed. In situations where a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be netted with the deferred tax asset. These amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. The adoption of this new guidance in the first quarter of fiscal 2014 did not have a material impact on our consolidated financial position, results of operations or cash flows. 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. This 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. The adoption of this new guidance in the first quarter of fiscal 2014 did not have a material impact on our consolidated financial position, results of operations or cash flows. Recently Issued Accounting Pronouncements – In April 2014, the FASB issued guidance on reporting discontinued operations and disclosures of disposals of components of an entity. This guidance raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. We will adopt these provisions in the first quarter of 2015 and we do not expect the adoption to have a material impact on our consolidated financial statements. |

Goodwill Changes in the carrying value of goodwill by reportable segment during the year ended December 28, 2013 and the three-month period ended March 29, 2014 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 2014 and 2013 was approximately $2.1 million and $1.7 million, respectively. The amounts included in the table above for the period ended March 29, 2014 exclude approximately $2.4 million and $4.1 million, related to the trade names of Rasco and Ismeca, respectively, and for the period ended December 28, 2013 exclude approximately $2.4 million and $4.0 million for such trade names, respectively, which have indefinite lives 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. |

Our cash, cash equivalents, and short-term investments consisted primarily of cash and other investment grade securities. 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 29, 2014 and December 28, 2013, 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 29, 2014 and December 28, 2013 these securities had amortized cost and fair value of $1.1 million and $1.2 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):

| Employee Stock Benefit Plans |
Our 2005 Equity Incentive Plan is a broad-based, long-term retention program intended to attract, motivate, and retain talented employees as well as align stockholder and employee interests. Awards that may be granted under the program include, but are not limited to, non-qualified and incentive stock options, restricted stock units, and performance-based stock units. We settle employee stock option exercises, ESPP purchases, and the vesting of restricted stock units, and performance-based stock units with newly issued common shares. At March 29, 2014, there were 628,165 shares available for future equity grants under the 2005 Equity Incentive Plan. Stock Options 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 and options generally vest and become exercisable after one year or in four annual increments beginning one year after the date of grant. Stock options granted under the program have a maximum contractual term of ten years. At March 29, 2014, we had 3,004,798 stock options outstanding. These options had a weighted-average exercise price of $11.89 per share, an aggregate intrinsic value of approximately $2.8 million and the weighted average remaining contractual term was approximately 5.1 years. At March 29, 2014, we had 2,333,487 stock options outstanding that were exercisable. These options had a weighted-average exercise price of $12.26 per share, an aggregate intrinsic value of $2.5 million and the weighted average remaining contractual term was approximately 4.3 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 28, 2013, we awarded restricted stock units covering 454,538 shares of our common stock to employees and at March 29, 2014, we had 1,131,871 restricted stock units outstanding with an aggregate intrinsic value of approximately $11.9 million and the weighted average remaining vesting period was approximately 1.9 years. Equity-Based Performance Stock Units Starting in 2012, we began issuing equity-based performance stock units (“PSUs”) 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 certain performance goals are met. The award measurement period is one fiscal year and 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 and vest over three years from the date of initial grant and upon final Board of Directors approval. On March 25, 2014, we issued 192,019 equity-based performance stock units to senior executives with vesting that is contingent on the level of achievement of certain performance goals, market return and continued service (“market-based PSUs”). The market-based PSUs issued in 2014 are subject to a one-year performance period after which the number of market-based PSUs earned will be determined and will then be subject to certain adjustments resulting from performance of Cohu’s Relative Total Shareholder Return (“TSR”) to a selected peer group over a two year measurement period following the date of grant with the total adjustment ranging from 75% to 125% of the target amount based on the percentage by which our TSR exceeds or falls below the selected peer group. Market-based PSUs earned will vest at the rate of 50% on the second and third anniversary of their grant. We estimated the fair value of market-based PSUs using a Monte Carlo simulation model on the date of grant. The model incorporates assumptions for the risk-free interest rate, Cohu and the selected peer group price volatility, the correlation between Cohu and the selected index, and dividend yields. Compensation expense is recognized ratably over the measurement period.
At March 29, 2014, we had 368,875 PSUs and market based PSUs outstanding with an aggregate intrinsic value of approximately $3.9 million and the weighted average remaining vesting period was approximately 2.0 years. Employee Stock Purchase Plan (ESPP) 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 ESPP shares were sold to our employees during the three-month period ended March 29, 2014 and we have 322,422 shares available for future issuance under the Plan.

| 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 29, 2014 and 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, since relatively small changes in our projected income or loss produce a significant variance in our ETR. The actual year-to-date ETR for the three months ended March 29, 2014 and March 30, 2013, was 1.6% and 6.3%, respectively. The tax benefit in 2014 and 2013 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 29, 2014. |

| 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 28, 2013 has been derived from our audited financial statements at that date. The interim condensed consolidated financial statements as of March 29, 2014 (also referred to as “the first quarter of fiscal 2014” and “the first three months of fiscal 2014”) and March 30, 2013 (also referred to as “the first quarter of fiscal 2013” and “the first three months of fiscal 2013”) 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 2014 and 2013 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 28, 2013, which are included in our 2013 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 $0.7 million and $0.6 million at March 29, 2014 and December 28, 2013, 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 29, 2014, 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 1st of each year, and have determined there is no impairment as of October 1, 2013 as we determined that the estimated fair values of our semiconductor equipment and microwave communications reporting units exceeded their carrying values by approximately 31% and 11%, respectively, on that date. 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 29, 2014 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 28, 2013. 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 29, 2014, we had deferred revenue totaling approximately $9.0 million and deferred profit of $6.3 million. At December 28, 2013, we had deferred revenue totaling approximately $7.4 million and deferred profit of $6.1 million. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Comprehensive Income | Comprehensive Income Our accumulated other comprehensive income balance totaled approximately $7.0 million and $6.7 million at March 29, 2014 and December 28, 2013, 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 to accumulated other comprehensive income during the first three months of fiscal 2014 and 2013 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 2014 and 2013 was not significant. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements – In July 2013, the Financial Accounting Standards Board (“FASB”) issued guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This amendment to previous income tax guidance clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax benefit is disallowed. In situations where a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be netted with the deferred tax asset. These amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. The adoption of this new guidance in the first quarter of fiscal 2014 did not have a material impact on our consolidated financial position, results of operations or cash flows. 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. This 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. The adoption of this new guidance in the first quarter of fiscal 2014 did not have a material impact on our consolidated financial position, results of operations or cash flows. Recently Issued Accounting Pronouncements – In April 2014, the FASB issued guidance on reporting discontinued operations and disclosures of disposals of components of an entity. This guidance raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. We will adopt these provisions in the first quarter of 2015 and we do not expect the adoption to have a material impact on our consolidated financial statements. |
