1.	Summary of Significant Accounting Policies

Basis of Presentation

Our fiscal years are based on a 52- or 53-week period ending on the last Saturday in December. The condensed consolidated balance sheet at December 29, 2012 has been derived from our audited financial statements at that date. The interim condensed consolidated financial statements as of September 28, 2013 (also referred to as “the third quarter of fiscal 2013” and “the first nine months of fiscal 2013”) and September 29, 2012 (also referred to as “the third quarter of fiscal 2012” and “the first nine months of fiscal 2012”) are unaudited. However, in management’s opinion, these financial statements reflect all adjustments (consisting only of normal, recurring items) necessary to provide a fair presentation of our financial position, results of operations and cash flows for the periods presented. The nine-month periods ended September 28, 2013 and September 29, 2012 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 29, 2012, which are included in our 2012 Annual Report on Form 10-K, filed with the U. S. Securities and Exchange Commission (“SEC”). In the following notes to our interim condensed consolidated financial statements, Cohu, Inc. is referred to as “Cohu”, “we”, “our” and “us”.

Risks and Uncertainties

We are subject to a number of risks and uncertainties that may significantly impact our future operating results. These risks and uncertainties are discussed under Item 1A. “Risk Factors” included in this Form 10-Q. Understanding these risks and uncertainties is integral to the review of our interim condensed consolidated financial statements.

Concentration of Credit Risk

Financial instruments that potentially subject us to significant credit risk consist principally of cash equivalents, short-term investments and trade accounts receivable. We invest in a variety of financial instruments and, by policy, limit the amount of credit exposure with any one issuer.

Trade accounts receivable are presented net of allowance for doubtful accounts of $0.8 million and $0.3 million at September 28, 2013 and December 29, 2012, respectively. Our customers include semiconductor manufacturers and semiconductor test subcontractors and other customers located throughout many areas of the world. While we believe that our allowance for doubtful accounts is adequate and represents our best estimate at September 28, 2013, we will continue to monitor customer liquidity and other economic conditions, which may result in changes to our estimates regarding collectability.

Goodwill, Other Intangible Assets and Long-lived Assets

We evaluate goodwill for impairment annually and when an event occurs or circumstances change that indicate that the carrying value may not be recoverable. We test goodwill for impairment by first comparing the book value of net assets to the fair value of the reporting units. If the fair value is determined to be less than the book value, a second step is performed to compute the amount of impairment as the difference between the estimated fair value of goodwill and the carrying value. We estimated the fair values of our reporting units primarily using the income approach valuation methodology that includes the discounted cash flow method, taking into consideration the market approach and certain market multiples as a validation of the values derived using the discounted cash flow methodology. Forecasts of future cash flows are based on our best estimate of future net sales and operating expenses, based primarily on customer forecasts, industry trade organization data and general economic conditions.

We conduct our annual impairment test as of October 1st of each year. Other events and changes in circumstances may also require goodwill to be tested for impairment between annual measurement dates. While a decline in stock price and market capitalization is not specifically cited as a goodwill impairment indicator, a company’s stock price and market capitalization should be considered in determining whether it is more likely than not that the fair value of a reporting unit is less that its carrying value. Additionally, a significant decline in a company’s stock price may suggest that an adverse change in the business climate may have caused the fair value of one or more reporting units to fall below their carrying value. The financial and credit market volatility directly impacts our fair value measurement through our stock price that we use to determine our market capitalization. During times of volatility, significant judgment must be applied to determine whether credit or stock price changes are a short-term swing or a longer-term trend. As of September 28, 2013 we do not believe there have been any events or circumstances that would require us to perform an interim goodwill impairment review, however, a sustained decline in Cohu’s market capitalization below its book value could lead us to determine, in a future period, that an interim goodwill impairment review is required and may result in an impairment charge which would have a negative impact on our results of operations.

Long-lived assets, other than goodwill, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used, or any other significant adverse change that would indicate that the carrying amount of an asset or group of assets may not be recoverable. For long-lived assets, impairment losses are only recorded if the asset’s carrying amount is not recoverable through its undiscounted, probability-weighted future cash flows. We measure the impairment loss based on the difference between the assets carrying amount and estimated fair value.

Share-Based Compensation

Share-based compensation expense related to stock options is recorded based on the fair value of the award on its grant date which we estimate using the Black-Scholes valuation model. Share-based compensation expense related to restricted stock unit awards is calculated based on the market price of our common stock on the grant date, reduced by the present value of dividends expected to be paid on our common stock prior to vesting of the restricted stock unit.

Reported share-based compensation is classified, in the condensed consolidated interim financial statements, as follows (in thousands):


	Three Months Ended				Nine Months Ended
	September 28, 2013		September 29, 2012		September 28, 2013		September 29, 2012
Cost of sales	$	50	$	49	$	250	$	279
Research and development		355		291		1,236		951
Selling, general and administrative		781		619		2,476		2,024

Total share-based compensation	$	1,186	$	959	$	3,962	$	3,254

Income (Loss) Per Share

Basic income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the reporting period. Diluted income per share includes the dilutive effect of common shares potentially issuable upon the exercise of stock options, vesting of outstanding restricted stock units and issuance of stock under our employee stock purchase plan using the treasury stock method. In loss periods, potentially dilutive securities are excluded from the per share computations due to their anti-dilutive effect. For purposes of computing diluted income per share, stock options with exercise prices that exceed the average fair market value of our common stock for the period are excluded. The following table reconciles the denominators used in computing basic and diluted income (loss) per share (in thousands):


	Three Months Ended				Nine Months Ended
	September 28, 2013		September 29, 2012		September 28, 2013		September 29, 2012
Weighted average common shares		24,929		24,479		24,801		24,421
Effect of dilutive stock options		—		—		—		—

		24,929		24,479		24,801		24,421

Revenue Recognition

Our revenue recognition policy is disclosed in Note 1 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 29, 2012. As more fully described in that policy, revenue from products that have not previously satisfied customer acceptance requirements is recognized upon customer acceptance. The gross profit on sales that are not recognized is generally recorded as deferred profit and reflected as a current liability in our consolidated balance sheet.

At September 28, 2013, we had deferred revenue totaling approximately $7.2 million and deferred profit of $5.5 million. At December 29, 2012, we had deferred revenue totaling approximately $3.6 million and deferred profit of $2.1 million.

Comprehensive Income

Our accumulated other comprehensive income balance totaled approximately $3.6 million and $1.8 million at September 28, 2013 and December 29, 2012, respectively, and was attributed to all non-owner changes in stockholders’ equity and consists of, on an after-tax basis where applicable, foreign currency adjustments resulting from the translation of certain accounts into U.S. dollars where the functional currency is the Euro or the Swiss Franc, unrealized gains and losses on investments and adjustments related to postretirement benefits. Reclassification adjustments to accumulated other comprehensive income during the first nine months of fiscal 2013 and 2012 were not significant.

Retiree Medical Benefits

We provide post-retirement health benefits to certain executives and directors under a noncontributory plan. The net periodic benefit cost incurred during the first nine months of fiscal 2013 and 2012 was not significant.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements – In July 2012, the Financial Accounting Standards Board (“FASB”) issued guidance to simplify the testing for a drop in value of intangible assets such as trademarks, patents, and distribution rights. The amended standard reduces the cost of accounting for indefinite-lived intangible assets, especially in cases where the likelihood of impairment is low. The changes permit businesses and other organizations to first use subjective criteria to determine if an intangible asset has lost value. The amendments will be effective for fiscal years starting after September 15, 2012 with early adoption permitted. The adoption of this new guidance in the first quarter of fiscal 2013 did not have a material impact on our consolidated financial position, results of operations or cash flows.

In February 2013, the FASB issued authoritative guidance that will require a public entity to present in its annual and interim financial statements information about reclassification adjustments from accumulated other comprehensive income in a single note or on the face of the financial statements. The adoption of this new guidance in the first quarter of fiscal 2013 did not have a material impact on our consolidated financial position, results of operations or cash flows.

Recently Issued Accounting Pronouncements – In July 2013, the FASB issued guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This amendment to previous income tax guidance clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax benefit is disallowed. In situations where a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be netted with the deferred tax asset. These amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. We are currently evaluating the impact our adoption of this new guidance in the first quarter of fiscal 2014 will have on our consolidated financial position, results of operations or cash flows.

In March 2013, the FASB issued guidance on a parent company’s accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. This new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The amendments will be effective for fiscal years and interim periods starting after December 15, 2013 with early adoption permitted. We do not believe our adoption of the new guidance in the first quarter of fiscal 2014 will have an impact on our consolidated financial position, results of operations or cash flows.
