| Significant Accounting Policies [Text Block] |
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 27, 2014 has been derived from our audited financial statements at that date. The interim condensed consolidated financial statements as of September 26, 2015 (also referred to as “the third quarter of fiscal 2015” and “the first nine months of fiscal 2015”) and September 27, 2014 (also referred to as “the third quarter of fiscal 2014” and “the first nine months of fiscal 2014”) 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 nine-month periods ended September 26, 2015 and September 27, 2014 were each comprised of 13 and 39 weeks, respectively. 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 27, 2014, which are included in our 2014 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”. Certain prior-period amounts in our condensed consolidated financial statements have been reclassified to conform to the current period presentation. These reclassifications have no effect on previously reported net income. 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. Discontinued Operations On June 10, 2015, we sold all of the outstanding stock of our mobile microwave communications equipment business, Broadcast Microwave Services, Inc. (“BMS”) and on June 6, 2014, we completed the sale of our video camera business, Cohu Electronics. The operating results of BMS and Cohu Electronics are being presented as discontinued operations and all prior period amounts have been reclassified accordingly. See Note 2, “Discontinued Operations” for additional information. Unless otherwise indicated, all amounts herein relate to continuing operations. 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 $0.1 million and $0.2 million at September 26, 2015 and December 27, 2014, respectively. Our customers include semiconductor manufacturers and semiconductor test subcontractors throughout many areas of the world. While we believe that our allowance for doubtful accounts is adequate and represents our best estimate at September 26, 2015, 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 goodwill impairment test as of October 1st of each year. As of October 1, 2014, we concluded there was no impairment as the estimated fair value of our reporting unit exceeded its carrying values by approximately 35%. 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 asset’s carrying amount and estimated fair value. Foreign Currency Translation Assets and liabilities of our wholly owned foreign subsidiaries that use the U.S. Dollar as their functional currency are translated using exchange rates in effect at the end of the period, except for nonmonetary assets, such as inventories and property, plant and equipment, which are translated using historical exchange rates. Revenues and costs are translated using average exchange rates for the period, except for costs related to those balance sheet items that are translated using historical exchange rates. Gains and losses on foreign currency transactions are recognized as incurred. Certain of our foreign subsidiaries have designated the local currency as their functional currency and, as a result, their assets and liabilities are translated at the rate of exchange at the balance sheet date, while revenue and expenses are translated using the average exchange rate for the period. During the three- and nine-month periods ended September 26, 2015, we recognized approximately $1.5 million and $1.1 million of foreign exchange gains in our consolidated statement of operations, respectively. During the three- and nine-month periods ended September 27, 2014, we recognized approximately $1.0 million and $0.9 million of foreign exchange gains in our consolidated statement of operations, respectively. Cumulative translation adjustments resulting from the translation of the financial statements are included as a separate component of stockholders’ equity. 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 (loss) 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 (loss) per share, stock options with exercise prices that exceed the average fair market value of our common stock for the period are excluded. For the three and nine months ended September 26, 2015, options to issue approximately 857,000 and 912,000 shares of common stock were excluded from the computation, respectively. For the three and nine months ended September 27, 2014, options to issue approximately 1,346,000 and 1,953,000 shares of common stock were excluded from the computation, respectively. The following table reconciles the denominators used in computing basic and diluted income (loss) per share ( in thousands) :
Cohu has utilized the “control number” concept in the computation of diluted earnings per share to determine whether potential common stock instruments are dilutive. The control number used is income from continuing operations. The control number concept requires that the same number of potentially dilutive securities applied in computing diluted earnings per share from continuing operations be applied to all other categories of income or loss, regardless of their anti-dilutive effect on such categories. 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 27, 2014. 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 September 26, 2015, we had deferred revenue totaling approximately $8.6 million and deferred profit of $5.7 million. At December 27, 2014, we had deferred revenue totaling approximately $10.7 million and deferred profit of $6.9 million. The periodic increase is primarily a result of deferrals of revenue associated with product shipments made to our customers in accordance with our revenue recognition policy. A small number of customers historically have been responsible for a significant portion of our net sales. Significant customer concentration information is as follows :
Comprehensive Loss Our accumulated other comprehensive loss balance totaled approximately $20.5 million and $10.7 million at September 26, 2015 and December 27, 2014, 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 of our subsidiary accounts where the functional currency is not the U.S. Dollar and adjustments related to postretirement benefits. Reclassification adjustments from accumulated other comprehensive income during the first nine months of fiscal 2015 and 2014 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 nine months of fiscal 2015 and 2014 was not significant. Recent Accounting Pronouncements Recently Issued Accounting Pronouncements – In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance on revenue from contracts with customers. The amended guidance outlines a single comprehensive revenue model for entities to use in accounting for revenue arising from contracts with customers. The guidance supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” Entities have the option of using either a full retrospective or modified approach to adopt the guidance. This guidance is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016. In April 2015, the FASB agreed to propose a one-year deferral of the revenue recognition standard's effective date for all entities, which would change the effectiveness to annual reporting periods beginning after December 15, 2017, with the option to adopt as early as December 15, 2016. We are currently evaluating the impact of the new guidance on our financial statements and have not yet determined which transition method we will utilize upon adoption or the potential impact of this new guidance on our consolidated financial statements.In August 2014, the FASB issued Accounting Standards Update (ASU) 2014-15, “Presentation of Financial Statements - Going Concern, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”. This standard sets forth management’s responsibility to evaluate, each reporting period, whether there is substantial doubt about an entity’s ability to continue as a going concern, and if so, to provide related footnote disclosures. The standard is effective for annual reporting periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016. The Company does not believe that the adoption of this guidance will have any material impact on its financial position or results of operations. In April 2015, the FASB issued ASU 2015-04, “Compensation - Retirement Benefits (Subtopic 715): Practical Expedient for the Measurement Date of an Employer's Defined Benefit Obligation and Plan Assets.” This update provides a practical expedient that permits a company to measure defined benefit plan assets and obligations using the month-end date that is closest to the company's fiscal year-end and apply that practical expedient consistently from year to year. The practical expedient should be applied consistently to all plans if the company has more than one plan. This ASU is effective prospectively for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11 “Simplifying the Measurement of Inventory” (ASU 2015-11). ASU 2015-11 simplifies the guidance on the subsequent measurement of inventory, excluding inventory measured using last-in, first out or the retail inventory method. Under the new standard, in scope inventory should be measured at the lower of cost and net realizable value. The new standard is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. We are evaluating the impact of the new standard on our consolidated financial statements and our timing for adoption. In September 2015, the FASB issued ASU 2015-16 “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments” (ASU 2015-16). ASU 2015-16 requires an entity to: recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined; record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date; and present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The new standard is effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted for financial statements that have not been issued. We do not expect the new standard to have a significant impact on our consolidated financial statements upon adoption. |

| Disposal Groups, Including Discontinued Operations, Disclosure [Text Block] |
In June 2015, we sold all of the outstanding stock of BMS for $8.0 million, comprised of a $5.5 million in cash and up to $2.5 million of contingent consideration. The sales price is subject to a working capital adjustment and, as a result, adjustments to the loss from sale reported below are possible. In June 2014, we sold substantially all the assets of our video camera business, Cohu Electronics for $9.5 million in cash and $0.5 million in contingent consideration. Our decision to sell these two non-core businesses resulted from management’s determination that they were no longer a strategic fit within our organization. As part of the divestiture of BMS we recorded a long-term contingent consideration receivable that has been classified as Level 3 in the fair value hierarchy. See Note 4, “Financial Instruments Measured at Fair Value” for additional information on the three-tier fair value hierarchy. The contingent consideration represents the estimated fair value of future payments we are due based on BMS achieving annual revenue targets in certain years as specified in the sale agreement. We determined the initial value of the contingent consideration by using the Monte Carlo simulation model and any future changes to the fair value of the contingent consideration will be recognized in earnings. Balance sheet information for BMS presented as discontinued operations is summarized as follows (in thousands) :
Operating results of our discontinued operations is summarized as follows (in thousands) :
During the third quarter of 2015, we recognized $0.2 million in additional loss from the disposal of BMS resulting from current period adjustments to contingent consideration and working capital as referenced above. We are still working to finalize the final working capital adjustment and additional adjustments may be required. In connection with the disposal of our two business segments we incurred divestiture-related costs that would not have been incurred otherwise. These costs consist of legal and investment banking advisory services, success based compensation arrangements and certain other items that are incremental to normal operating charges and were expensed as incurred. These costs are included in the gain (loss) from sale amounts presented above. Divestiture-related costs associated with the sale of BMS incurred in the first six months of 2015 totaled $1.0 million and similar costs associated with the sale of Cohu Electronics incurred in the first six months of 2014 totaled $0.8 million. There were no divestiture-related costs incurred during the third quarter of 2015 or 2014. |

| Goodwill and Intangible Assets Disclosure [Text Block] |
Changes in the carrying value of goodwill during the year ended December 27, 2014 and the nine-month period ended September 26, 2015 were as follows ( in thousands ):
Purchased intangible assets, subject to amortization are as follows ( in thousands ):
Amortization expense related to intangible assets was approximately $1.7 million in the third quarter of fiscal 2015 and $5.3 million in the first nine months of fiscal 2015. Amortization expense related to intangible assets was approximately $2.0 million in the third quarter of fiscal 2014 and $6.0 million in the first nine months of fiscal 2014. The amounts included in the table above for the period ended September 26, 2015 exclude approximately $1.9 million and $3.7 million, for trade names of Rasco and Ismeca, respectively. For the period ended December 27, 2014 these amounts were approximately $2.1 million and $3.6 million for Rasco and Ismeca, respectively. Changes in the carrying values of these intangible assets are a result of the impact of fluctuations in currency exchange rates. Previously, it has been our determination that the Rasco and Ismeca trade names had an indefinite life. On September 24, 2015, we introduced a rebranding initiative and unveiled a new “Cohu” logo. The primary goal of the change was to improve the cohesiveness of our organization and come to the market as one brand. We review the assessment of indefinite life for our trade names each period to determine whether the indefinite life assumption continues to be supportable. If it is deemed unsupportable the change in useful life from indefinite to finite is made and amortization is recognized on a prospective basis. As a result of the rebranding initiative, we determined that the classification of the useful life of our trade names as indefinite was no longer appropriate based on our expectations of the future period over which they will provide economic benefit to Cohu. When an intangible asset that is not being amortized is subsequently determined to have a finite useful life there is a requirement for the asset to be tested for impairment in accordance with ASC 350, “Intangibles - Goodwill and Other”. We have completed an interim impairment assessment that indicates the fair value of the Rasco and Ismeca trade names, as of September 24, 2015, exceed their carrying values by 4% and 17%, respectively. We believe the assumptions used in the interim impairment analysis are reasonable. However, the analysis is sensitive to adverse changes in the assumptions used in the valuations. In particular, changes in the projected cash flows, discount rates, royalty rates and other market based assumptions could produce significantly different results for the impairment analysis which could result in future impairment charges. |

| Fair Value, Measurement Inputs, Disclosure [Text Block] |
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 are as follows (in thousands) :
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 financial instruments that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy (in thousands) :

Our 2005 Equity Incentive Plan (the “2005 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, employee stock purchase plan purchases, and the vesting of restricted stock units, and performance-based stock units with newly issued common shares. On May 12, 2015, our stockholders approved an amendment to the 2005 Plan which increased the number of shares that may be issued under the 2005 Plan by 1,500,000 shares. Subsequent to this amendment, at September 26, 2015, there were 2,257,363 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 September 26, 2015, we had 2,031,539 stock options outstanding. These options had a weighted-average exercise price of $11.20 per share, an aggregate intrinsic value of approximately $1.3 million and the weighted average remaining contractual term was approximately 4.7 years. At September 26, 2015, we had 1,720,111 stock options outstanding that were exercisable. These options had a weighted-average exercise price of $11.43 per share, an aggregate intrinsic value of $1.2 million and the weighted average remaining contractual term was approximately 4.2 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. In the nine months ended September 26, 2015 , we awarded restricted stock units covering 482,101 shares of our common stock to employees and at September 26, 2015, we had 1,097,429 restricted stock units outstanding with an aggregate intrinsic value of approximately $10.6 million and the weighted average remaining vesting period was approximately 1.4 years. Equity-Based Performance Stock Units In March 2012, we began granting equity-based performance units covering shares of our common stock to certain employees. The number of shares of stock ultimately issued will depend upon the extent to which certain financial performance goals set by our Board of Directors are met during the one-year award measurement period. Based upon the level of achievement of performance goals the number of shares we ultimately issue can range from 0% up to 150% of the number of shares under each grant which vest over 3 years from the date of initial grant. In 2014, we began awarding 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”) and in 2015, the market-based PSUs granted are only 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 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. Compensation expense is recognized ratably over the measurement period of each vesting tranche based on our current assessment of achievement of the performance goals. New shares of our common stock will be issued on the date the equity-based performance units vest. In the nine months ended September 26, 2015 , we awarded 156,370 market-based performance stock units to senior executives, and at September 26, 2015, we had 376,374 PSUs and market based PSUs outstanding with an aggregate intrinsic value of approximately $3.6 million and the weighted average remaining vesting period was approximately 1.3 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. On May 12, 2015 our stockholders approved an amendment to the Plan which increased the number of shares that may be issued under the Plan by 750,000 shares. During the three-month period ended September 26, 2015, no shares of our common stock were sold to our employees under the Plan leaving 864,321 shares available for future issuance. |

| Income Tax Disclosure [Text Block] |
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 and nine months ended September 26, 2015 and September 27, 2014, we used the actual year-to-date ETR in computing our tax provision, as a reliable estimate of the annual ETR cannot be made, since relatively small changes in our projected income produce a significant variation in our ETR. The actual year-to-date ETR on income from continuing operations for the three months ended September 26, 2015 and September 27, 2014 , was 41.3% and 16.7%, respectively, and for the nine months ended September 26, 2015 and September 27, 2014 was 39.1% and 21.6%, respectively. The tax provision on income from continuing operations in 2015 and 2014 differs from the U.S. federal statutory rate primarily due to the lack of a provision (benefit) on our domestic income (losses) as a result of our valuation allowance on deferred tax assets, foreign income taxed at lower rates, changes in our deferred tax asset valuation allowance, state taxes and interest related to unrecognized tax benefits. Other than for foreign currency exchange rate changes, there was no material change to our unrecognized tax benefits and interest accrued related to unrecognized tax benefits during the three or nine month periods ended September 26, 2015 and September 27, 2014. |

| Commitments Contingencies and Guarantees [Text Block] |
Product Warranty Our products are generally sold with warranty periods that range from 12 to 36 months following sale or acceptance. Parts and labor are covered under the terms of the warranty agreement. The warranty provision is based on historical and projected experience by product and configuration. Changes in accrued warranty were as follows ( in thousands ):
Accrued warranty amounts expected to be incurred after one year are included in non-current other accrued liabilities in the condensed consolidated balance sheet. These amounts total $1.2 million at September 26, 2015 and $1.0 million at December 27, 2014. Prior-period long-term accrued warranty amounts have been reclassified to a long term liability in the December 31, 2014 balance sheet to conform to the current period presentation. This reclassification had no effect on previously reported net income and is considered immaterial. Standby Letters of Credit From time-to-time, during the ordinary course of business, we provide standby letters of credit for certain contingent liabilities under contractual arrangements, including customer contracts. As of September 26, 2015, the maximum potential amount of future payments that Cohu could be required to make under these standby letters of credit was approximately $0.2 million. We have not recorded any liability in connection with these guarantee arrangements beyond that required to appropriately account for the underlying transaction being guaranteed. We do not believe, based on historical experience and information currently available, that it is probable that any amounts will be required to be paid under these arrangements. |

| Disposal Groups, Including Discontinued Operations, Disclosure [Text Block] |
In June 2015, we sold all of the outstanding stock of BMS for $8.0 million, comprised of a $5.5 million in cash and up to $2.5 million of contingent consideration. The sales price is subject to a working capital adjustment and, as a result, adjustments to the loss from sale reported below are possible. In June 2014, we sold substantially all the assets of our video camera business, Cohu Electronics for $9.5 million in cash and $0.5 million in contingent consideration. Our decision to sell these two non-core businesses resulted from management’s determination that they were no longer a strategic fit within our organization. As part of the divestiture of BMS we recorded a long-term contingent consideration receivable that has been classified as Level 3 in the fair value hierarchy. See Note 4, “Financial Instruments Measured at Fair Value” for additional information on the three-tier fair value hierarchy. The contingent consideration represents the estimated fair value of future payments we are due based on BMS achieving annual revenue targets in certain years as specified in the sale agreement. We determined the initial value of the contingent consideration by using the Monte Carlo simulation model and any future changes to the fair value of the contingent consideration will be recognized in earnings. Balance sheet information for BMS presented as discontinued operations is summarized as follows (in thousands) :
Operating results of our discontinued operations is summarized as follows (in thousands) :
During the third quarter of 2015, we recognized $0.2 million in additional loss from the disposal of BMS resulting from current period adjustments to contingent consideration and working capital as referenced above. We are still working to finalize the final working capital adjustment and additional adjustments may be required. In connection with the disposal of our two business segments we incurred divestiture-related costs that would not have been incurred otherwise. These costs consist of legal and investment banking advisory services, success based compensation arrangements and certain other items that are incremental to normal operating charges and were expensed as incurred. These costs are included in the gain (loss) from sale amounts presented above. Divestiture-related costs associated with the sale of BMS incurred in the first six months of 2015 totaled $1.0 million and similar costs associated with the sale of Cohu Electronics incurred in the first six months of 2014 totaled $0.8 million. There were no divestiture-related costs incurred during the third quarter of 2015 or 2014. |

| Accounting Policies [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis of Accounting, Policy [Policy Text Block] | 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 27, 2014 has been derived from our audited financial statements at that date. The interim condensed consolidated financial statements as of September 26, 2015 (also referred to as “the third quarter of fiscal 2015” and “the first nine months of fiscal 2015”) and September 27, 2014 (also referred to as “the third quarter of fiscal 2014” and “the first nine months of fiscal 2014”) 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 nine-month periods ended September 26, 2015 and September 27, 2014 were each comprised of 13 and 39 weeks, respectively. 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 27, 2014, which are included in our 2014 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”. Certain prior-period amounts in our condensed consolidated financial statements have been reclassified to conform to the current period presentation. These reclassifications have no effect on previously reported net income. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risks and Uncertainties [Policy Text Block] | 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. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Discontinued Operations, Policy [Policy Text Block] | Discontinued Operations On June 10, 2015, we sold all of the outstanding stock of our mobile microwave communications equipment business, Broadcast Microwave Services, Inc. (“BMS”) and on June 6, 2014, we completed the sale of our video camera business, Cohu Electronics. The operating results of BMS and Cohu Electronics are being presented as discontinued operations and all prior period amounts have been reclassified accordingly. See Note 2, “Discontinued Operations” for additional information. Unless otherwise indicated, all amounts herein relate to continuing operations. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Concentration Risk, Credit Risk, Policy [Policy Text Block] | 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 $0.1 million and $0.2 million at September 26, 2015 and December 27, 2014, respectively. Our customers include semiconductor manufacturers and semiconductor test subcontractors throughout many areas of the world. While we believe that our allowance for doubtful accounts is adequate and represents our best estimate at September 26, 2015, we will continue to monitor customer liquidity and other economic conditions, which may result in changes to our estimates regarding collectability. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block] | 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 goodwill impairment test as of October 1st of each year. As of October 1, 2014, we concluded there was no impairment as the estimated fair value of our reporting unit exceeded its carrying values by approximately 35%. 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 asset’s carrying amount and estimated fair value. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currency Translation Assets and liabilities of our wholly owned foreign subsidiaries that use the U.S. Dollar as their functional currency are translated using exchange rates in effect at the end of the period, except for nonmonetary assets, such as inventories and property, plant and equipment, which are translated using historical exchange rates. Revenues and costs are translated using average exchange rates for the period, except for costs related to those balance sheet items that are translated using historical exchange rates. Gains and losses on foreign currency transactions are recognized as incurred. Certain of our foreign subsidiaries have designated the local currency as their functional currency and, as a result, their assets and liabilities are translated at the rate of exchange at the balance sheet date, while revenue and expenses are translated using the average exchange rate for the period. During the three- and nine-month periods ended September 26, 2015, we recognized approximately $1.5 million and $1.1 million of foreign exchange gains in our consolidated statement of operations, respectively. During the three- and nine-month periods ended September 27, 2014, we recognized approximately $1.0 million and $0.9 million of foreign exchange gains in our consolidated statement of operations, respectively. Cumulative translation adjustments resulting from the translation of the financial statements are included as a separate component of stockholders’ equity. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | 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) :
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Earnings Per Share, Policy [Policy Text Block] | 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 (loss) 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 (loss) per share, stock options with exercise prices that exceed the average fair market value of our common stock for the period are excluded. For the three and nine months ended September 26, 2015, options to issue approximately 857,000 and 912,000 shares of common stock were excluded from the computation, respectively. For the three and nine months ended September 27, 2014, options to issue approximately 1,346,000 and 1,953,000 shares of common stock were excluded from the computation, respectively. The following table reconciles the denominators used in computing basic and diluted income (loss) per share ( in thousands) :
Cohu has utilized the “control number” concept in the computation of diluted earnings per share to determine whether potential common stock instruments are dilutive. The control number used is income from continuing operations. The control number concept requires that the same number of potentially dilutive securities applied in computing diluted earnings per share from continuing operations be applied to all other categories of income or loss, regardless of their anti-dilutive effect on such categories. |

| Revenue Recognition, Policy [Policy Text Block] | 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 27, 2014. 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 September 26, 2015, we had deferred revenue totaling approximately $8.6 million and deferred profit of $5.7 million. At December 27, 2014, we had deferred revenue totaling approximately $10.7 million and deferred profit of $6.9 million. The periodic increase is primarily a result of deferrals of revenue associated with product shipments made to our customers in accordance with our revenue recognition policy. A small number of customers historically have been responsible for a significant portion of our net sales. Significant customer concentration information is as follows :
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Comprehensive Income, Policy [Policy Text Block] | Comprehensive Loss Our accumulated other comprehensive loss balance totaled approximately $20.5 million and $10.7 million at September 26, 2015 and December 27, 2014, 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 of our subsidiary accounts where the functional currency is not the U.S. Dollar and adjustments related to postretirement benefits. Reclassification adjustments from accumulated other comprehensive income during the first nine months of fiscal 2015 and 2014 were not significant. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Pension and Other Postretirement Plans, Policy [Policy Text Block] | 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 nine months of fiscal 2015 and 2014 was not significant. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements Recently Issued Accounting Pronouncements – In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance on revenue from contracts with customers. The amended guidance outlines a single comprehensive revenue model for entities to use in accounting for revenue arising from contracts with customers. The guidance supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” Entities have the option of using either a full retrospective or modified approach to adopt the guidance. This guidance is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016. In April 2015, the FASB agreed to propose a one-year deferral of the revenue recognition standard's effective date for all entities, which would change the effectiveness to annual reporting periods beginning after December 15, 2017, with the option to adopt as early as December 15, 2016. We are currently evaluating the impact of the new guidance on our financial statements and have not yet determined which transition method we will utilize upon adoption or the potential impact of this new guidance on our consolidated financial statements.In August 2014, the FASB issued Accounting Standards Update (ASU) 2014-15, “Presentation of Financial Statements - Going Concern, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”. This standard sets forth management’s responsibility to evaluate, each reporting period, whether there is substantial doubt about an entity’s ability to continue as a going concern, and if so, to provide related footnote disclosures. The standard is effective for annual reporting periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016. The Company does not believe that the adoption of this guidance will have any material impact on its financial position or results of operations. In April 2015, the FASB issued ASU 2015-04, “Compensation - Retirement Benefits (Subtopic 715): Practical Expedient for the Measurement Date of an Employer's Defined Benefit Obligation and Plan Assets.” This update provides a practical expedient that permits a company to measure defined benefit plan assets and obligations using the month-end date that is closest to the company's fiscal year-end and apply that practical expedient consistently from year to year. The practical expedient should be applied consistently to all plans if the company has more than one plan. This ASU is effective prospectively for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11 “Simplifying the Measurement of Inventory” (ASU 2015-11). ASU 2015-11 simplifies the guidance on the subsequent measurement of inventory, excluding inventory measured using last-in, first out or the retail inventory method. Under the new standard, in scope inventory should be measured at the lower of cost and net realizable value. The new standard is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. We are evaluating the impact of the new standard on our consolidated financial statements and our timing for adoption. In September 2015, the FASB issued ASU 2015-16 “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments” (ASU 2015-16). ASU 2015-16 requires an entity to: recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined; record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date; and present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The new standard is effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted for financial statements that have not been issued. We do not expect the new standard to have a significant impact on our consolidated financial statements upon adoption. |
