Significant Accounting Policies [Text Block]

Summary of Significant Accounting Policies

Basis of Presentation

– Cohu, Inc. (“Cohu”, “we”, “our” and “us”), through our wholly owned subsidiaries, is a provider of semiconductor test equipment. Our Consolidated Financial Statements include the accounts of Cohu and our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates.

Our fiscal years are based on a

- or

-week period ending on the last Saturday in

December.

Our current fiscal year which ended on

December 30, 2017,

consisted of

weeks. Our fiscal years ended on

December 31, 2016,

and

December 26, 2015,

consisted of

weeks and

weeks, respectively.

Discontinued Operations

– On

June 10, 2015,

we sold our mobile microwave communications equipment business, Broadcast Microwave Services, Inc. (“BMS”). See Note

11,

“Discontinued Operations

” for additional information. Unless otherwise indicated, all amounts herein relate to continuing operations.

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 and performance 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 years ended

December 30, 2017,

December 31, 2016,

and

December 26, 2015,

approximately

77,000,

697,000

and

875,000

shares of our 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)	2017		2016		2015
Weighted average common shares outstanding		27,836		26,659		26,057
Effect of dilutive stock options and restricted stock units		1,080		821		731
		28,916		27,480		26,788

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.

Cash, Cash Equivalents and Short-term Investments

– Highly liquid investments with insignificant interest rate risk and original maturities of

three

months or less are classified as cash and cash equivalents. Investments with maturities greater than

three

months are classified as short-term investments. All of our short-term investments are classified as available-for-sale and are reported at fair value, with any unrealized gains and losses, net of tax, recorded in the statement of comprehensive income (loss). We manage our cash equivalents and short-term investments as a single portfolio of highly marketable securities. We have the ability and intent, if necessary, to liquidate any of our investments in order to meet the liquidity needs of our current operations during the next

months. Accordingly, investments with contractual maturities greater than

one

year have been classified as current assets in the accompanying consolidated balance sheets.

Fair Value of Financial Instruments

– The carrying amounts of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses, approximate fair value due to the short maturities of these financial instruments.

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

$0.2

million at

December 30, 2017,

and

$0.1

million at

December 31, 2016.

Our customers primarily include semiconductor manufacturers and semiconductor test subcontractors located throughout many areas of the world. While we believe that our allowance for doubtful accounts is adequate and represents our best estimate of potential loss exposure at

December 30, 2017,

we will continue to monitor customer liquidity and other economic conditions, which

may

result in changes to our estimates regarding collectability.

Inventories

– Inventories are stated at the lower of cost, determined on a

first

-in,

first

-out basis, or net realizable value. Cost includes labor, material and overhead costs. Determining market value of inventories involves numerous estimates and judgments including projecting average selling prices and sales volumes for future periods and costs to complete and dispose of inventory. As a result of these analyses, we record a charge to cost of sales in advance of the period when the inventory is sold when estimated market values are below our costs. Charges to cost of sales for excess and obsolete inventories totaled

$1.1

million in both

2017

and

2016

and were

$2.4

million

2015.

Property, Plant and Equipment

– Depreciation and amortization of property, plant and equipment is calculated principally on the straight-line method based on estimated useful lives of

thirty

forty

years for buildings,

five

fifteen

years for building improvements and

three

ten

years for machinery, equipment and software. Land is

not

depreciated.

Property, plant and equipment, at cost, consisted of the following

Segment Information

– We applied the provisions of ASC Topic

280,

Segment Reporting

, (“ASC

280”

), which sets forth a management approach to segment reporting and establishes requirements to report selected segment information quarterly and to report annually entity-wide disclosures about products, major customers and the geographies in which the entity holds material assets and reports revenue. An operating segment is defined as a component that engages in business activities whose operating results are reviewed by the chief operating decision maker and for which discrete financial information is available. Based on the provisions of ASC

280,

we have determined that our identified operating segments, which are Digital Test Handlers (DTH), Analog Test Handlers (ATH) and Integrated Test Solutions (ITS), qualify for aggregation under ASC

280

due to similarities in their customers, their economic characteristics, and the nature of products and services provided. As a result, we report in

one

segment, semiconductor equipment.

Goodwill, Purchased Intangible Assets and Other 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 determined there was

impairment as of

October

2017

as we determined that the estimated fair values of our reporting units exceeded their carrying values on that date. Other events and changes in circumstances

may

also require goodwill to be tested for impairment between annual measurement dates. As of

December 30, 2017,

we do

not

believe there have been any events or circumstances that would require us to perform an interim goodwill impairment review. In the event we determine that an interim goodwill impairment review is required, in a future period, the review

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.

Product Warranty

– Product warranty costs are accrued in the period sales are recognized. Our products are generally sold with standard warranty periods, which differ by product, ranging from

- to

-months. Parts and labor are typically covered under the terms of the warranty agreement. Our warranty expense accruals are based on historical and estimated costs by product and configuration. From time-to-time we offer customers extended warranties beyond the standard warranty period. In those situations the revenue relating to the extended warranty is deferred at its estimated fair value and recognized on a straight-line basis over the contract period. Costs associated with our extended warranty contracts are expensed as incurred.

Income Taxes

– We assess our income tax positions and record tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances and information available at the reporting dates. For those tax positions where it is more-likely-than-

not

that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than

percent likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is

not

more-likely-than-

not

that a tax benefit will be sustained,

tax benefit has been recognized in the financial statements. Where applicable, associated interest and penalties have also been recognized and recorded, net of federal and state tax benefits, in income tax expense.

The U.S. Tax Cuts and Jobs Act (“Tax Act”

) was enacted on

December 22, 2017.

Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, we have made reasonable estimates of the effects and recorded provisional amounts in our financial statements for the year ended

December 30, 2017

as provided for in SEC Staff Accounting Bulletin

No.

118

(“SAB

118”

). As we collect and prepare necessary data, and interpret any additional guidance issued by the U.S. Treasury Department, the IRS or other standard-setting bodies, we

may

make adjustments to the provisional amounts. Those adjustments

may

materially impact the provision for income taxes and the effective tax rate in the period in which the adjustments are made. The accounting for the tax effects of the enactment of the Tax Act will be completed in

2018.

Contingencies and Litigation

– We assess the probability of adverse judgments in connection with current and threatened litigation. We would accrue the cost of an adverse judgment if, in our estimation, the adverse outcome is probable and we can reasonably estimate the ultimate cost.

Revenue Recognition

– Our net sales are derived from the sale of products and services and are adjusted for estimated returns and allowances, which historically have been insignificant. We recognize revenue when there is persuasive evidence of an arrangement, title and risk of loss have passed, delivery has occurred or the services have been rendered, the sales price is fixed or determinable and collection of the related receivable is reasonably assured. Title and risk of loss generally pass to our customers upon shipment. In circumstances where either title or risk of loss pass upon destination or acceptance, we defer revenue recognition until such events occur.

Revenue for established products that have previously satisfied a customer

’s acceptance requirements and provide for full payment tied to shipment is generally recognized upon shipment and passage of title. In certain instances, customer payment terms

may

provide that a minority portion (e.g. up to

20%

) of the equipment purchase price be paid only upon customer acceptance. In those situations, the majority portion (e.g.

80%

) of revenue where the contingent payment is tied to shipment and the entire product cost of sale are recognized upon shipment and passage of title and the minority portion of the purchase price related to customer acceptance is deferred and recognized upon receipt of customer acceptance. In cases where a prior history of customer acceptance cannot be demonstrated or from sales where customer payment dates are

not

determinable and in the case of new products, revenue is deferred until customer acceptance has been received. Our post-shipment obligations typically include installation and standard warranties. The estimated fair value of installation related revenue is recognized in the period the installation is performed. Service revenue is recognized ratably over the period of the related contract or upon completion of the services if they are short-term in nature. Spares and kit revenue is generally recognized upon shipment.

Certain of our equipment sales are accounted for as multiple-element arrangements. A multiple-element arrangement is a transaction which

may

involve the delivery or performance of multiple products, services, or rights to use assets, and performance

may

occur at different points in time or over different periods of time.

For arrangements containing multiple elements, the revenue relating to the undelivered elements is deferred using the relative selling price method utilizing estimated sales prices until delivery of the deferred elements. We limit the amount of revenue recognition for delivered elements to the amount that is

not

contingent on the future delivery of products or services, future performance obligations or subject to customer-specified return or adjustment.

On shipments where sales are

not

recognized, gross profit is generally recorded as deferred profit in our consolidated balance sheet representing the difference between the receivable recorded and the inventory shipped. In certain instances where customer payments are received prior to product shipment, the customer

’s payments are recorded as customer advances. At

December 30, 2017,

we had total deferred revenue of approximately

$10.4

million and total deferred profit of

$7.4

million. Deferred profit expected to be recognized after

one

year, totaling

$0.8

million at

December 30, 2017,

is included in noncurrent other accrued liabilities in our consolidated balance sheet. At

December 31, 2016,

we had total deferred revenue of approximately

$9.3

million and deferred profit of

$6.9

million.

December 31, 2017,

the

first

day of our fiscal

2018,

we will adopt

ASU

No.

2014

09,

Revenue from Contracts with Customers (Topic

606

)

(ASU

2014

), which amends the existing accounting standards for revenue recognition.

For additional information on the impact this new standard will have on our revenue recognition in the future see recently issued accounting pronouncements below.

Advertising Costs

– Advertising costs are expensed as incurred and were

not

material for all periods presented.

Share-based Compensation

– We measure and recognize all share-based compensation under the fair value method. Our estimate of share-based compensation expense requires a number of complex and subjective assumptions including our stock price volatility, employee exercise patterns (expected life of the options) and related tax effects. The assumptions used in calculating the fair value of share-based awards represent our best estimates, but these estimates involve inherent uncertainties and the application of management judgment. Although we believe the assumptions and estimates we have made are reasonable and appropriate, changes in assumptions could materially impact our reported financial results.

Foreign Remeasurement and Currency Translation

– Assets and liabilities of our wholly owned foreign subsidiaries that use the U.S. Dollar as their functional currency are re-measured 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 re-measured using historical exchange rates. Revenues and costs are re-measured using average exchange rates for the period, except for costs related to those balance sheet items that are re-measured using historical exchange rates. Gains and losses on foreign currency transactions are recognized as incurred.

During the year ended

December 30, 2017,

we recognized foreign exchange losses totaling

$3.0

million that are included in our consolidated statement of income. During the years ended

December 31, 2016,

and

December 26, 2015,

we recognized approximately

$2.6

million and

$1.4

million, respectively, of foreign exchange gains.

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. Cumulative translation adjustments resulting from the translation of the financial statements are included as a separate component of stockholders

’ equity.

Accumulated Other Comprehensive Loss

– Our accumulated other comprehensive loss totaled approximately

$17.8

million at

December 30, 2017,

and

$27.9

million at

December 31, 2016,

and was attributed to, net of income taxes where applicable: foreign currency adjustments resulting from the translation of certain accounts into U.S. Dollars, unrealized losses and gains on investments and adjustments to accumulated postretirement benefit obligations. The U.S. Dollar weakened relative to certain foreign currencies in countries where we have operations as of

December 30, 2017,

compared to

December 31, 2016.

Consequently, our accumulated other comprehensive loss decreased by

$11.3

million as a result of foreign currency translation during

2017.

In the previous year, strengthening of the U.S. Dollar led to an increase in our accumulated other comprehensive loss of

$5.8

million. Additional information related to accumulated other comprehensive loss, on an after-tax basis is included in Note

10.

2016.

This standard simplifies or clarifies several aspects of the accounting for equity-based payment awards, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Certain of these changes are required to be applied retrospectively, while other changes are required to be applied prospectively.

We elected to eliminate the use of an estimated forfeiture rate and recognize actual forfeitures as they occur. We adopted this amendment on a modified retrospective basis and, as a result, we recorded a

$0.2

million cumulative effect adjustment to retained earnings at

December 27, 2015,

) – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost

, which provides additional guidance on the presentation of net periodic pension and postretirement benefit costs in the income statement and on the components eligible for capitalization. The amendments in this guidance require that an employer report the service cost component of the net periodic benefit costs in the same income statement line item as other compensation costs arising from services rendered by employees during the period. The non-service-cost components of net periodic benefit costs are to be presented in the income statement separately from the service cost components and outside a subtotal of income from operations. The guidance also allows for the capitalization of the service cost components, when applicable (i.e., as a cost of internally manufactured inventory or a self-constructed asset). The guidance is effective for annual periods beginning after

December 15, 2017,

including interim periods within those annual periods; early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have

We will adopt the new standard effective

December 31, 2017,

which is the

two

methods of adoption: retrospectively to each prior reporting period presented (the full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective method).

We plan on adopting the standard using the modified retrospective method. We have completed our analysis on the impact this guidance will have on our consolidated financial statements and are still in the process of evaluating the impact on our disclosures. Based on our review of our customer agreements, our revenue will continue to be recognized at a point in time, generally upon shipment of products to customers, consistent with our current revenue recognition model. In certain instances, when customer payment terms provide that a minority portion of the equipment purchase price be paid only upon customer acceptance, recognition of revenue

may

occur sooner under the new model. When adopting the new standard, on

December 31, 2017,

approximately

$1.3

million of revenue that was

not

recognized in fiscal

2017,

because the equipment had

not

been accepted by the customer will be

recognized net of

$0.2

million related tax effect as a cumulative catch-up adjustment to the opening balance of retained earnings as opposed to being recognized as future revenue upon acceptance.

Business Acquisitions

January 4, 2017,

we completed

the acquisition of all the outstanding stock of Kita Manufacturing Co., LTD. and Kita USA, Inc. (together “Kita”) (the “Acquisition”). Kita, headquartered in Osaka, Japan, and with operations in Attleboro, Massachusetts and Kyoto, Japan, designs, manufactures and sells spring probe contacts used in final test contactors, probe cards, PCB test boards and connectors sold to customers worldwide. The acquisition of Kita was a strategic transaction to expand our total available market, extend our market leadership and broaden our product offerings. In connection with the Acquisition, during the years ended

December 30, 2017,

and

December 31, 2016,

we incurred acquisition related costs, which were expensed to selling, general and administrative, totaling

$0.4

million and

$1.8

million, respectively.

The Acquisition has been accounted for in conformity with FASB ASC

805,

Business Combinations (“ASC

). The purchase price for Kita was funded primarily by cash reserves and consisted of the following (

in thousands

Cash paid to Kita shareholders	$	15,000
Fair value of contingent consideration		823
Total purchase price	$	15,823

The contingent consideration represents the estimated fair value of future payments totaling up to

$3.0

million that we would be required to make as a result of Kita achieving annual revenue and EBITDA targets in

2017

and

2018

as specified in the purchase agreement for the Acquisition. The fair value of the contingent consideration recognized on the acquisition date and at

December 30, 2017,

was estimated using the Monte Carlo simulation model. Adjustments to the fair value of contingent consideration are reflected in selling, general, and administrative expense in our consolidated statements of income. We have classified the contingent consideration payable as level

in the fair value hierarchy. See Note

“Financial Instruments Measured at Fair Value” for additional information on the

three

-tier fair value hierarchy.

The

2017

revenue and EBITDA targets were achieved and a payment of

$1.5

2018.

The fair value of the contingent consideration is recorded in our consolidated balance sheets in both other current accrued liabilities and long term other accrued liabilities.

The Acquisition was nontaxable to Cohu and certain of the assets acquired, including goodwill and intangibles, will

not

be deductible for tax purposes. The acquired assets and liabilities of Kita were recorded at their respective fair values including an amount for goodwill representing the difference between the Acquisition consideration and the fair value of the identifiable net assets and was allocated to our ITS operating segment.

Product backlog		100	1
Trade names		400	5
Total intangible assets	$	2,100

Acquired intangible assets reported above are being amortized using the straight-line method over their estimated useful lives.

The value assigned to the developed technology was determined by using the multi-period excess earnings method under the income approach. Developed technology, which comprises products that have reached technological feasibility, includes the products in Kita

’s product line. The revenue estimates used to value the developed technology were based on estimates of relevant market sizes and growth factors, expected trends in technology and the nature and expected timing of new product introductions by Kita and its competitors. The estimated cash flows were based on revenues for the developed technology net of operating expenses and net of contributory asset charges. The discount rate utilized to discount the net cash flows of the developed technology to present value was based on the risk associated with the respective cash flows taking into consideration the perceived risk of the technology relative to the other acquired assets, the weighted average cost of capital, the internal rate of return, and the weighted average return on assets.

The value assigned to customer relationships was determined by using the with and without method under the income approach, which analyzes the difference in discounted cash flows generated with the customer relationships in place compared to the discounted cash flows generated without the customer relationships in place.

The value assigned to the covenant

not

-to-compete was estimated based upon the with and without method of the income approach. Specifically, the present value of the differential of the projected cash flows with and without the covenant in place was measured utilizing the appropriate expected rate of return.

The value assigned to backlog acquired was estimated based upon the contractual nature of the backlog as of the acquisition date, using the income approach to discount back to present value the cash flows attributable to the backlog.

The value assigned to trade names was estimated using the relief-from-royalty method of the income approach. This approach is based on the assumption that in lieu of ownership, a company would be willing to pay a royalty in order to exploit the related benefits of this intangible asset.

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

and introduces significant changes to U.S. income tax law. Effective in

2018,

the Tax Act reduces the U.S. statutory tax rate from

35%

21%

and creates new taxes on certain foreign-sourced earnings and related-party payments, which are referred to as the global intangible low-taxed income tax and the base erosion and anti-abuse tax, respectively. In addition, in

2017

we were subject to a

one

-time transition tax on accumulated foreign subsidiary earnings

not

previously subject to U.S. income tax. The Tax Act also repealed the alternative minimum tax (AMT) effective

and made changes to net operating loss provisions, expensing of certain assets and capitalization of research and development expense with such changes effective for

2018

and later years.

Provisional amounts for the following income tax effects of the Tax Act have been recorded as of

December 30, 2017,

and are subject to change during

2018.

One-time transition tax

The Tax Act requires us to pay U.S. income taxes on accumulated foreign subsidiary earnings

not

previously subject to U.S. income tax at a rate of

15.5%

to the extent of foreign cash and certain other net current assets and

on the remaining earnings. Foreign tax credits and net operating losses

may

be used to reduce this tax which is referred to as a transition or deemed repatriation tax. We recorded a provisional amount for our

one

-time transition tax liability of

$16.6

million and used foreign tax credits and net operating losses to fully offset this liability. We have recorded provisional amounts based on estimates of the effects of the Tax Act as the analysis requires significant data from our foreign subsidiaries that is

not

regularly collected or analyzed.

Deferred tax effects

The Tax Act reduces the U.S. statutory tax rate from

35%

21%

for years after

2017.

Accordingly, we have remeasured our deferred taxes as of

December 30, 2017

to reflect the reduced rate that will apply in future periods when these deferred taxes are settled or realized. We recognized a deferred tax benefit of

$4.0

million, net of a reduction in the related valuation allowance, to reflect the reduced U.S. tax rate and other effects of the Tax Act including the change in the life of NOL carryforwards from

years to indefinite. Although the tax rate reduction is known, we have

not

collected the necessary data to complete our analysis of the effect of the Tax Act on the underlying deferred taxes and as such, the amounts recorded as of

December 30, 2017

are provisional.

Beginning in

2018,

the Tax Act provides a

100%

deduction for dividends received from

-percent owned foreign corporations by U.S. corporate shareholders, subject to a

one

-year holding period. Although dividend income is now exempt from U.S. federal tax i

n the hands of U.S. corporate shareholders, companies must still apply the guidance of ASC

740

to account for the tax consequences of outside basis differences and other tax impacts of their investments in non-U.S. subsidiaries. Deferred tax liabilities are recognized for taxes payable on the unremitted earnings from foreign operations of our subsidiaries, except where it is our intention to indefinitely reinvest a portion or all of these undistributed earnings.

As we complete our analysis of the Tax Act and incorporate additional guidance that

may

be issued by the U.S. Treasury Department, the IRS or other standard-setting bodies, we

may

identify additional effects

not

reflected as of

December 30, 2017.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and tax purposes. Significant components of our deferred tax assets and liabilities were as follows:

(in thousands)	2017			2016
Deferred tax assets:
Inventory, receivable and warranty reserves	$	3,417		$	5,868
Net operating loss carryforwards		7,467			11,681
Tax credit carryforwards		14,724			13,715
Accrued employee benefits		4,796			5,002
Deferred profit and gain on facility sale		3,617			5,412
Stock-based compensation		1,897			4,189
Acquisition basis differences		1,606			1,334
Other		208			103
Gross deferred tax assets		37,732			47,304
Less valuation allowance		(31,491	)		(44,731	)
Total deferred tax assets		6,241			2,573
Deferred tax liabilities:
Depreciation and fixed asset related		120			53
Acquisition basis differences		5,518			7,423
Unremitted earnings of foreign subsidiaries		2,002			-
Other		437			662
Total deferred tax liabilities		8,077			8,138
Net deferred tax liabilities	$	(1,836	)	$	(5,565	)

Companies are required to assess whether a valuation allowance should be recorded against their deferred tax assets (“DTAs”) based on the consideration of all available evidence, using a “more likely than

not”

realization standard. The

four

sources of taxable income that must be considered in determining whether DTAs will be realized are, (

) future reversals of existing taxable temporary differences (i.e. offset of gross deferred tax assets against gross deferred tax liabilities); (

) taxable income in prior carryback years, if carryback is permitted under the tax law; (

) tax planning strategies and (

) future taxable income exclusive of reversing temporary differences and carryforwards.

In assessing whether a valuation allowance is required, significant weight is to be given to evidence that can be objectively verified. We have evaluated our DTAs each reporting period, including an assessment of our cumulative income or loss over the prior

three

-year period and future periods, to determine if a valuation allowance was required. A significant negative factor in our assessment was Cohu's

three

-year cumulative U.S. loss history at the end of various fiscal periods including

2017.

As a result of our cumulative,

three

-year U.S. GAAP pretax loss from continuing operations at the end of

2017

we were unable to conclude at

December 30, 2017,

that it was “more likely than

not”

that our U.S. DTAs would be realized. We will evaluate the realizability of our DTAs at the end of each quarterly reporting period in

2018

and should circumstances change it is possible the remaining valuation allowance, or a portion thereof, will be reversed in a future period.

Our valuation allowance on our DTAs at

December 30, 2017,

and

December 31, 2016,

was approximately

$31.5

million and

$44.7

million, respectively. The remaining gross DTAs for which a valuation allowance was

not

recorded are realizable primarily through future reversals of existing taxable temporary differences.

As the realization of DTAs is determined by tax jurisdiction, the deferred tax liabilities recorded as part of the

2008

acquisition of Rasco, a German corporation, the fiscal

2013

acquisition of Ismeca, a Swiss Corporation, and the fiscal

2017

acquisition of Kita Japan, a Japanese company were

not

a source of taxable income in assessing the realization of our DTAs in the U.S.

The reconciliation of income tax computed at the U.S. federal statutory tax rate to the provision for income taxes for continuing operations is as follows:

(in thousands)	2017			2016			2015
Tax provision at U.S. 35% statutory rate	$	12,378		$	2,102		$	2,801
Impact of Tax Act, before reduction in valuation allowance		12,397			-			-
State income taxes, net of federal tax benefit		56			168			(152	)
Settlements, adjustments and releases from statute expirations		(1,731	)		(312	)		(104	)
Federal tax credits		(371	)		(183	)		(221	)
Stock-based compensation		(2,801	)		168			156
Change in valuation allowance		(13,484	)		2,430			2,181
Non-deductible transaction related costs		577			463			-
Foreign income taxed at different rates		(4,866	)		(2,378	)		(2,601	)
Other, net		89			289			151
	$	2,244		$	2,747		$	2,211

Our effective tax rate for each of the years presented was impacted by earnings realized in foreign jurisdictions with statutory tax rates lower than the U.S. federal statutory tax rate. Included in

2017

foreign income taxed at different rates is

$2.0

million of foreign withholding tax that we accrued in the event we repatriate funds from certain of our foreign subsidiaries. Beginning in

2018,

earnings realized in foreign jurisdictions will be subject to U.S. tax in accordance with the Tax Act. State income taxes, net of federal benefit, have been reduced by research tax credits totaling approximately

$0.2

million,

$0.2

million and

$0.4

million in

2017,

2016

and

2015,

respectively.

December 30, 2017,

we had federal and state net operating loss carryforwards of approximately

$31.2

million and

$19.0

million, respectively, that expire in various tax years beginning in

2018

through

2036

or have

expiration date. We also have federal and state tax credit carryforwards at

December 30, 2017

of approximately

$7.6

million and

$14.1

million, respectively, certain of which expire in various tax years beginning in

2018

through

2037

or have

expiration date. The federal and state loss and credit carryforwards are subject to annual limitations under Sections

382

and

383

of the Internal Revenue Code and applicable state tax law. We believe the state tax credit is

not

likely to be realized.

We have certain tax holidays with respect to our operations in Malaysia and the Philippines. These holidays require compliance with certain conditions and expire at various dates through

2027.

The impact of these holidays was an increase in net income of approximately

$2.8

million or

$0.10

per share in

2017,

$1.0

million, or

$0.04

per share, in

2016

and

$0.8

million, or

$0.03

per share, in fiscal

2015.

A reconciliation of our gross unrecognized tax benefits, excluding accrued interest and penalties, is as follows:

(in thousands)	2017			2016			2015
Balance at beginning of year	$	10,075		$	10,444		$	10,841
Gross additions for tax positions of current year		200			125			215
Gross additions for tax positions of prior years		958			58			248
Reductions due to lapse of the statute of limitations		(1,148	)		(446	)		(243	)
Foreign exchange rate impact		236			(106	)		(617	)
Balance at end of year	$	10,321		$	10,075		$	10,444

The gross additions for tax positions of prior years is primarily related to the Kita acquisition.

If the unrecognized tax benefits at

December 30, 2017

are ultimately recognized, approximately

$4.3

million (

$5.2

million at

December 31, 2016)

would result in a reduction in our income tax expense and effective tax rate. It is reasonably possible that our gross unrecognized tax benefits as of

December 30, 2017,

could decrease in

2018

by approximately

$0.6

million as a result of the expiration of certain statutes of limitations.

We recognize interest and penalties related to unrecognized tax benefits in income tax expense. Cohu had approximately

$1.1

million and

$1.2

million accrued for the payment of interest and penalties at

December

30,

2017,

and

December 31, 2016,

respectively. Interest expense, net of accrued interest reversed, was $(

0.3

) million in

2017,

not

significant in

2016

and

$0.1

million in

2015.

Our U.S. federal and state income tax returns for years after

2013

and

2012,

respectively, remain open to examination, subject to the statute of limitations. Net operating loss and credit carryforwards arising prior to these years are also open to examination if and when utilized. The statute of limitations for the assessment and collection of income taxes related to our foreign tax returns varies by country. In the foreign countries where we have significant operations these time periods generally range from

four

ten

years after the year for which the tax return is due or the tax is assessed.

Employee Benefit Plans

Defined Contribution Retirement Plans

– We maintain a defined contribution

401

(k) retirement savings plan covering all salaried and hourly U.S. employees. Participation is voluntary and participants’ contributions are based on their eligible compensation. We match contributions of participants at

50%

up to

of salary contributed, up to various statutory limits. In both

2017

and

2016

we made matching contributions to the plan of

$0.6

million. In

2015

we made contributions to the plan of

$0.7

million.

Defined Benefit Retirement Plans

– As a result of the acquisition of Ismeca effective

December 31, 2012,

we took over the Ismeca Europe Semiconductor BVG Pension Plan in Switzerland (“the Swiss Plan”) and the following discussion only relates to the Swiss Plan.

Net

periodic benefit cost of the Swiss Plan was as follows

(in thousands)	2017			2016			2015
Service cost	$	907		$	868		$	856
Interest cost		198			245			311

Settlements		-			-			235
Net periodic costs	$	986		$	966		$	1,209

The following table sets forth the projected benefit obligation, the fair value of plan assets, the funded status and the liability we have recorded in our consolidated balance sheet related to the Swiss Plan:

December 30, 2017,

and

December 31, 2016,

the Swiss Plan

’s net liability is included in noncurrent accrued retirement benefits. Amounts recognized in accumulated other comprehensive income net of tax related to the Swiss Plan consisted of an unrecognized net actuarial loss totaling

$3.1

million at

December 30, 2017,

and

$2.4

million at

December 31, 2016.

Weighted-average actuarial assumptions used to determine the projected benefit obligation under the Swiss Plan

are as follows

	2017		2016
Discount rate		0.7%		0.7%
Compensation increase		1.8%		1.5%

Weighted-average assumptions used to determine net periodic benefit cost of the Swiss Plan

are as follows

	2017		2016		2015
Discount rate		0.7%		1.0%		1.3%
Rate of return on Assets		0.7%		1.0%		1.3%
Compensation increase		1.5%		1.8%		1.8%

During

2018

employer and employee contributions to the Swiss Plan are expected to total

$0.8

million. Estimated benefit payments are expected to be as follows:

2018

$0.8

million;

2019

$0.9

million;

2020

$0.9

million;

2021

$1.1

million;

2022

$0.9

million; and

$6.0

million thereafter through

2027.

As is customary with Swiss pension plans, the assets of the plan are invested in a collective fund with multiple employers. We have

investment authority over the assets of the plan that are held and invested by a Swiss insurance company. Investment holdings are made with respect to Swiss laws and target allocations for plan assets are

68%

debt securities and cash,

15%

real estate investments,

alternative investments and

equity securities. The valuation of the collective fund assets as a whole is a Level

measurement; however the individual investments of the fund are generally Level

(equity securities), Level

(fixed income) and Level

(real estate and alternative) investments. We determine the fair value of the plan assets based on information provided by the collective fund, through review of the collective fund

’s annual financial statements. See Note

“Financial Instruments Measured at Fair Value” for additional information on the

three

-tier fair value hierarchy.

We maintain

other defined benefit plans for employees located outside the U.S. for which the majority of the obligations and net periodic benefit cost were determined to be immaterial for all periods presented.

Retiree Medical Benefits

– We provide post-retirement health benefits to certain executives and directors under a noncontributory plan. The net periodic benefit cost was

$0.1

million in

2017,

2016,

and

2015.

We fund benefits as costs are incurred and as a result there are

plan assets.

The weighted average discount rate used in determining the accumulated post-retirement benefit obligation was

3.4%

2017,

3.9%

2016

and

4.2%

2015.

The annual rates of increase of the cost of health benefits was assumed to be

9.2%

2018.

This rate was then assumed to decrease

0.5%

per year to

4.5%

2027

and remain level thereafter. A

one

percent increase (decrease) in health care cost trend rates would increase (decrease) the

2017

net periodic benefit cost by approximately

$13,000

(

$11,000

) and the accumulated post-retirement benefit obligation as of

December 30, 2017,

by approximately

$419,000

(

$354,000

Contributions to the post-retirement health benefit plan are expected to total

$0.1

million in

2018.

Estimated benefit payments are expected to be as follows:

2018

$0.1

million;

2019

$0.1

million;

2020

$0.1

million;

2021

$0.1

million;

2022

$0.2

million and

$0.9

million thereafter through

2027.

Deferred Compensation

– The Cohu, Inc. Deferred Compensation Plan allows certain of our officers to defer a portion of their current compensation. We have purchased life insurance policies on the participants with Cohu as the named beneficiary. Participant contributions, distributions and investment earnings and losses are accumulated in a separate account for each participant. At

December 30, 2017,

the payroll liability to participants, included in accrued compensation and benefits in the consolidated balance sheet, was approximately

$2.3

million and the cash surrender value of the related life insurance policies included in other current assets was approximately

$2.2

million. At

December 31, 2016,

the liability totaled

$2.4

million and the corresponding assets were

$2.2

million.

Employee Stock Purchase Plan

– The Cohu, Inc.

1997

Employee Stock Purchase Plan (“the Plan”) provides for the issuance of a maximum of

2,650,000

shares of our common stock. Under the Plan, eligible employees

may

purchase shares of common stock through payroll deductions. The price paid for the common stock is equal to

85%

of the fair market value of our common stock on specified dates. During the last

three

years we issued shares under the Plan as follows:

2017

99,144;

2016

110,579

and

2015

122,528.

December 30, 2017,

there were

601,340

shares reserved for issuance under the Plan.

Stock Options

– At

December 30, 2017,

a total of

1,503,078

shares were available for future equity grants under the Cohu, Inc.

2005

Equity Incentive Plan (“the

2005

Plan”). Under the

2005

Plan stock options

may

be granted to employees, consultants and outside directors to purchase a fixed number of shares of our common stock at prices

not

less than

100%

of the fair market value at the date of grant. Options generally vest and become exercisable after

one

year or in

four

annual increments beginning

one

year after the grant date and expire

ten

years from the grant date. We have historically issued new shares of Cohu common stock upon share option exercise.

Stock option activity under our share-based compensation plans was as follows:

Restricted Stock Units

– Under our equity incentive plans, restricted stock units

may

be granted to employees, consultants and outside directors. Restricted stock units vest over a

one

-year,

two

-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. New shares of our common stock will be issued on the date the restricted stock units vest net of the statutory tax withholding requirements to be paid by us on behalf of our employees. As a result, the actual number of shares issued will be fewer than the actual number of RSUs outstanding at

December 30, 2017.

Restricted stock unit activity under our share-based compensation plans was as follows

Equity-Based Performance Stock Units

–

We grant performance stock units (“PSUs”) to certain senior executives as a part of our long-term equity compensation program. The performance criteria for the PSUs granted in

2017,

2016

and

2015

is based on a combination of the Company’s annualized Total Shareholder Return (“TSR”) for the performance period and the relative performance of the Company’s TSR compared with the annualized TSR of certain peer companies for the performance period. The PSU awards granted in

2014

had a

one

-year performance period after which the number of shares of our common stock earned, if any, was determined, subject to certain adjustments resulting from the performance of our TSR relative to a pre-selected competitor group over the

two

-year period following the date of grant. The number of shares of common stock that will ultimately be issued to settle PSUs granted over the last

four

years is as follows:

Year Grante d	Range of Award s				Performance Criteria Period (in years)
201 7		25%	-	200%		3
201 6		25%	-	200%		3
201 5		25%	-	200%		2
201 4		0%	-	150%		2

PSUs granted in

2017

and

2016

vest

100%

on the

third

anniversary of their grant and PSUs granted in

2015

and

2014

vest

50%

on the

second

and

third

anniversary of their grant, respectively.

We estimated the fair value of the PSUs using a Monte Carlo simulation model on the date of grant. Compensation expense is recognized over the derived service period. New shares of our common stock will be issued on the date the PSUs vest net of the minimum statutory tax withholding requirements to be paid by us on behalf of our employees. As a result, the actual number of shares issued will be fewer than the actual number PSUs outstanding at

December 30, 2017.

Share-based Compensation

– We estimate the fair value of each share-based award on the grant date using the Black-Scholes and the Monte Carlo simulation valuation models. Option valuation models require the input of highly subjective assumptions and changes in the assumptions used can materially affect the grant date fair value of an award. These assumptions for the Black-Scholes model include the risk-free rate of interest, expected dividend yield, expected volatility, and the expected life of the award. The risk-free rate of interest is based on the U.S. Treasury rates appropriate for the expected term of the award as of the grant date. Expected dividends are based primarily on historical factors related to our common stock. Expected volatility is based on historic weekly stock price observations of our common stock during the period immediately preceding the share-based award grant that is equal in length to the award’s expected term. We believe that historical volatility is the best estimate of future volatility. Expected life of the award is based on historical option exercise data. The Monte Carlo simulation 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. Share-based compensation expense related to restricted stock unit awards is calculated based on the market price of our common stock on the date of grant, reduced by the present value of dividends expected to be paid on our common stock prior to vesting of the restricted stock unit.

The following weighted average assumptions were used to value share-based awards granted:

Employee Stock Purchase Plan	2017	2016	2015
Dividend yield	1.4%	2.0%	2.2%
Expected volatility	33.3%	31.2%	35.3%
Risk-free interest rate	0.7%	0.3%	0.1%
Expected term (years)	0.5	0.5	0.5

We elected to early adopt ASU

in the

fourth

quarter of

2016,

which among other items, provides an accounting policy election to account for forfeitures as they occur, rather than based on an estimate of expected forfeitures. We elected to account for forfeitures as they occur and therefore, share-based compensation expense for the years ended

December 30, 2017,

and

December 31, 2016,

have been calculated based on actual forfeitures in our consolidated statement of income, rather than our previous approach where the expense was net of estimated forfeitures determined at the grant date. The net cumulative effect of this change was recognized as a

$0.2

million increase to paid-in capital and a decrease to retained earnings as of

December 27, 2015.

Share-based compensation expense for the year ended

December 26, 2015,

was recorded net of estimated forfeitures.

December 30, 2017,

we had less than

$0.1

0.2

Segment and Geographic Information

We applied the provisions of ASC

280,

which sets forth a management approach to segment reporting, establishes requirements to report selected segment information quarterly and to report annually entity-wide disclosures about products, major customers and the geographies in which the entity holds material assets and reports revenue. An operating segment is defined as a component that engages in business activities whose operating results are reviewed by the chief operating decision maker and for which discrete financial information is available. Based on the provisions of ASC

280,

we have determined that our identified operating segment

s, which are Digital Test Handlers (DTH), Analog Test Handlers (ATH) and Integrated Test Solutions (ITS), qualify for aggregation under ASC

280

due to similarities in their customers, their economic characteristics, and the nature of products and services provided and, as a result we report in

one

segment, semiconductor equipment. As a result, the financial information disclosed herein materially represents all of the financial information related to our semiconductor equipment segment.

We also assumed term loans from a series of Japanese financial institutions primarily related to the expansion of Kita

’s facility in Osaka, Japan. The loans are collateralized by the facility and land, carry interest rates ranging from

0.05%

2015,

we sold all of the outstanding stock of BMS for

$4.9

million in cash and up to

$2.5

million of contingent cash consideration. Our decision to sell this non-core business resulted from management’s determination that they were

longer a strategic fit within our organization.

As part of the divestiture of BMS we recorded a contingent consideration receivable that was been classified as Level

in the fair value hierarchy. See Note

“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

2016

and

2017

as specified in the sale agreement. We determined the value of the contingent consideration using a Monte Carlo simulation model with changes to the fair value of the contingent consideration being recognized in discontinued operations. During

Sale Leaseback Transactions [Text Block]	13. Sale-leaseback of Poway Facility On December 4, 2015, we completed the sale of our headquarters facility located in Poway, California (the “Poway Facility”) for $34.1 million. After payment of commissions and other fees associated with the sale we realized net cash proceeds of approximately $33.3 million which resulted in a total gain of $18.5 million. Concurrent with the closing of the sale, we entered into a lease, with a ten -year term through 2025, that provides for base rent of approximately $1.6 million per annum, with 3% annual adjustments for inflation and a pro rata share of property operating costs. The lease covers approximately 43% (unaudited) of the Poway Facility. This lease also contains two five -year renewal options. We accounted for this transaction in accordance with ASC subtopic 840 - 40, Sale-leaseback transactions , and recognized a gain on the sale-leaseback totaling $3.2 million for the year ended December 26, 2015. The remaining $15.3 million portion of the gain not recognized at the time of sale was deferred and is being recognized on a straight-line basis over the 10 -year lease term in line with the recognition of rental expense related to the lease. During the years ended December 30, 2017, and December 31, 2016, we amortized $1.5 million and $2.0 million of the deferred gain to income, respectively.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill, Purchased Intangible Assets and Other 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

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

We conduct our annual impairment test as of

of each year, and determined there was

impairment as of

October

may

also require goodwill to be tested for impairment between annual measurement dates. As of

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

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.

As of December 30, 2017, the cost and fair value of investments with loss positions were approximately $13.2 million. As of December 31, 2016, the cost and fair value of investments with loss positions were approximately $26.6 million. We evaluated the nature of these investments, credit worthiness of the issuer and the duration of these impairments to determine if an other-than-temporary decline in fair value had occurred and concluded that these losses were temporary and we have the ability and intent to hold these investments to maturity.
