[1]	In the fourth quarter of fiscal 2012, we recorded an income tax benefit in the amount of $25.5 million from the release of deferred tax asset valuation allowances due to deferred tax liabilities established on the acquired identifiable intangible assets from our acquisition of MicroProbe and $3.3 million benefit from the settlement of patent litigation in conjunction with the acquisition of MicroProbe. The fourth quarter of fiscal 2012 includes the following Microprobe operating activity: $19.8 million in revenue, $5.4 million amortization of intangibles, $2.6 million release of pre-existing backlog, $3.5 million release of inventory fair value step-up and $0.2 million charge for step-up depreciation on fixed assets resulting in a net loss of $6.4 million.
[2]	In the second quarter of fiscal 2012, we recorded a tax benefit in the amount of $1.6 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2012.
[3]	In the second quarter of fiscal 2011, we recorded a tax benefit in the amount of $2.5 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2011.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Formation and Business of the Company	Formation and Business of the Company FormFactor, Inc. ("FormFactor" or the "Company" and also referred to as "we" or "our") was incorporated in Delaware on April 15, 1993 and designs, develops, manufactures, sells and supports precision, high performance advanced semiconductor wafer probe cards. We are based in Livermore, California, home to our corporate offices, research and development, and manufacturing locations. We have facilities in the United States, Singapore, Japan, Taiwan, South Korea and the People's Republic of China. Fiscal Year Our fiscal year ends on the last Saturday in December. The fiscal years ended on December 29, 2012 and December 25, 2010, respectively, consisted of 52 weeks and the fiscal year ended on December 31, 2011 consisted of 53 weeks. Business Acquisition On October 16, 2012, we completed the acquisition of Astria Semiconductor Holdings, Inc., including its major subsidiary MicroProbe (together "MicroProbe"), which we refer to as the "MicroProbe Acquisition". As part of the Acquisition, a wholly-owned subsidiary of FormFactor merged with and into MicroProbe, with MicroProbe continuing as the surviving corporation and as a wholly-owned subsidiary of FormFactor. For additional information regarding the Acquisition see Note 3. Reclassifications Certain reclassifications have been made to the prior year's Consolidated Balance Sheet to conform to the current year's presentation. Out of Period Adjustment In the third quarter of fiscal 2010, we recorded a $4.1 million adjustment to cost of revenues net of $0.5 million income tax benefit, which resulted from an error in the calculation of capitalized manufacturing variances starting in the first quarter of fiscal 2009 through the second quarter of fiscal 2010. The error caused the understatement of cost of revenues and the overstatement of the overhead capitalized in inventory for most quarters. The income tax benefit resulted from a higher net loss in 2009 due to higher costs of revenue. The increase in the 2009 loss allowed us to recover more of our prior year tax payments. Of the total adjustment of $4.1 million to cost of revenues, $2.9 million , net of $0.5 million income tax benefit, was related to fiscal 2009. Management and the Audit Committee believe that such amounts are not material to current and previously reported financial statements.

Summary of Significant Accounting Policies

Basis of Consolidation and Foreign Currency Translation

The consolidated financial statements include our accounts and those of our wholly owned subsidiaries. All material intercompany balances and transactions have been eliminated.

The functional currencies of certain of our foreign subsidiaries are the local currencies and accordingly, all assets and liabilities of these foreign operations are translated to U.S. Dollars at current period end exchange rates, and revenues and expenses are translated to U.S. Dollars using average exchange rates in effect during the period. The gains and losses from the foreign currency translation of these subsidiaries' financial statements are included as a separate component of stockholders' equity under “Accumulated other comprehensive income.”

Certain other of our foreign subsidiaries in the People's Republic of China, Taiwan, Hong Kong, South Korea and Singapore use the U.S. Dollar as their functional currency. Accordingly, monetary assets and liabilities in non-functional currencies of these subsidiaries are remeasured using exchange rates in effect at the end of the period. Revenues and costs in local currency are remeasured using average exchange rates for the period, except for costs related to those balance sheet items that are remeasured using historical exchange rates. The resulting remeasurement gains and losses are included in the Consolidated Statements of Operations as incurred.

Use of Estimates

The preparation of consolidated 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 reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates may change as new information is obtained. We believe that the estimates, assumptions and judgments involved in revenue recognition, fair value of marketable securities, allowance for doubtful accounts, reserves for product warranty, valuation of obsolete and slow moving inventory, business combinations, legal contingencies, realizability of goodwill, the assessment of recoverability of long-lived assets, valuation and recognition of stock-based compensation, provision or benefit for income taxes and related deferred tax assets, valuation and tax liabilities and accruals for other liabilities have the greatest potential impact on our consolidated financial statements. Actual results could differ from those estimates.

Business Acquisitions

Our consolidated financial statements include the operations of an acquired business after the completion of the acquisition. We account for acquired businesses using the acquisition method of accounting. The acquisition method of accounting for acquired businesses requires, among other things, that most assets acquired and liabilities assumed be recognized at their estimated fair values as of the acquisition date, and that the fair value of acquired intangibles including in-process research and development (IPR&D) be recorded on the balance sheet. Also, transaction costs are expensed as incurred. Any excess of the purchase price over the assigned values of the net assets acquired is recorded as goodwill.

Cash, Cash Equivalents and Marketable Securities

Cash and cash equivalents consist of deposits and financial instruments which are readily convertible into cash and have original maturities of 90 days or less at the time of acquisition. Marketable securities consist primarily of highly liquid investments with maturities of greater than 90 days when purchased. We generally classify our marketable securities at the date of acquisition as available-for-sale. These securities are reported at fair value with the related unrealized gains and losses included in "Accumulated other comprehensive income", a component of stockholder's equity, net of tax. Any unrealized losses which are considered to be other-than-temporary impairments are recorded in "Other income, net" in the Consolidated Statements of Operations. Realized gains (losses) on the sale of marketable securities are determined using the specific-identification method and recorded in "Other income, net" in the Consolidated Statements of Operations. We measure our cash equivalents and marketable securities at fair value.

All of our available-for-sale investments are subject to a periodic impairment review. We record a charge to earnings when a decline in fair value is significantly below cost basis and judged to be other-than-temporary, or have other indicators of impairments. If the fair value of an available-for-sale investment is less than its amortized cost basis, an other-than-temporary impairment is triggered in circumstances where (1) we intend to sell the instrument, (2) it is more likely than not that we will be required to sell the instrument before recovery of its amortized cost basis or (3) a credit loss exists where we do not expect to recover the entire amortized cost basis of the instrument. If we intend to sell or it is more likely than not that we will be required to sell the available-for-sale investment before recovery of its amortized cost basis, we recognize an other-than- temporary impairment charge equal to the entire difference between the investment's amortized cost basis and its fair value.

Fair Value of Financial Instruments

We have evaluated the estimated fair value of financial instruments using available market information and valuations as provided by third-party sources. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. The fair value of the Company's cash, cash equivalents, accounts receivable, accounts payable and other current liabilities approximate their carrying amounts due to the relatively short maturity of these items. The carrying amounts of certain of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, accrued compensation and other accrued liabilities, approximate fair value because of their short maturities. Estimates of fair value of our marketable securities are based on quoted market prices from active markets or third party, market-based pricing sources which we believe to be reliable. These estimates represent the third parties' good faith opinion as to what a buyer in the marketplace would pay for a security in a current sale.

Whenever possible, the fair values of our financial assets and liabilities are determined using quoted market prices of identical assets or quoted market prices of similar assets from active markets. The three levels of inputs that may be used to measure fair value are as follows:


•	Level 1 valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.


•	Level 2 inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices near the reporting date in markets that are less active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.


•	Level 3 valuations are based on unobservable inputs to the valuation methodology and include our own data about assumptions market participants would use in pricing the asset or liability based on the best information available under the circumstances.

Each level of input has different levels of subjectivity and difficulty involved in determining fair value.

Foreign Exchange Management

We transact business in various foreign currencies. We enter into forward foreign exchange contracts in an effort to mitigate the risks associated with currency fluctuations on certain foreign currency balance sheet exposures. Gains and losses resulting from the impact of currency exchange rate movements on forward foreign exchange contracts designated to offset certain foreign currency balance sheet exposures are recognized as "Other income (expense), net" in the Consolidated Statements of Operations in the period in which the exchange rates change. These gains and losses are intended to partially offset the foreign currency exchange gains and losses on the underlying exposures being hedged. We record the fair value of these contracts as of the end of our reporting period in the Consolidated Balance Sheet. We do not use derivative financial instruments for trading or speculative purposes.

Restricted Cash

Under the terms of one of our facility leases, we provide security to the landlord in the form of letters of credit. As of December 29, 2012 and December 31, 2011, restricted cash included $0.3 million and $0.3 million, respectively, of letters of credit secured by a certificate of deposit.

Inventories

Inventories are stated at the lower of cost (principally standard cost which approximates actual cost on a first-in, first-out basis) or market value. The provision for potentially excess and obsolete inventory is made based on management's analysis of inventory levels, past usage and forecasted future sales and market conditions. On a quarterly basis, we review inventory quantities on hand and on order under non-cancelable purchase commitments in comparison to our past usage and estimated forecast of product demand for the next six months to determine what inventory quantities, if any, may not be sellable. Based on this analysis, we write down the affected inventory value for estimated excess and obsolescence charges. At the point of loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Shipping and handling costs are classified as a component of "Cost of revenues" in the Consolidated Statements of Operations.

We design, manufacture and sell a fully custom product into a market that has been subject to cyclicality and significant demand fluctuations. Probe cards are complex products, custom to a specific chip design and have to be delivered on short lead-times. Probe cards are manufactured in low volumes, but for certain materials, the material purchases are often subject to minimum purchase order quantities in excess of the actual underlying probe card demand. It is not uncommon for us to acquire production materials and commence production activities based on estimated production yields and forecasted demand prior to or in excess of actual demand for our wafer probe cards. These factors result in normal recurring inventory valuation adjustments to cost of revenues. Aggregate inventory write downs were $7.2 million , $7.9 million and $11.4 million for fiscal 2012, 2011 and 2010, respectively. We retain a portion of the excess inventory until the customer's design is discontinued. The inventory may be used to satisfy customer warranty demand.

When our products have been delivered, but the revenue associated with that product is deferred because the related revenue recognition criteria have not been met, we defer the related inventory costs. The deferred inventory costs do not exceed the deferred revenue amounts. The deferred inventory costs are classified as a component of "Prepaid expenses and other current assets" in the Consolidated Balance Sheet.

Property, Plant, and Equipment

Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation is provided on a straight-line method over the following estimated useful lives of the assets: 1 to 5 years for machinery and equipment, 1 to 5 years for computer equipment and software and 1 to 5 years for furniture and fixtures. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the related asset. Construction-in-progress assets are not depreciated until the assets are placed in service. Upon sale or retirement of assets, the cost and related accumulated depreciation or amortization, are removed from the balance sheet and the resulting gain or loss is reflected in operations.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed. We have determined that we operate in a single segment and have a single reporting unit associated with the design, development, manufacture, sale and support of precision, high performance advanced semiconductor wafer probe cards. In September 2011, the Financial Accounting Standards Board ("FASB") amended its guidance to simplify the testing of goodwill for impairment, allowing an entity to first assess qualitative factors to determine whether it is necessary to perform a two-step quantitative goodwill impairment test. If an entity determines as a result of the qualitative assessment that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative impairment test is required. Otherwise, no further testing is required. The performance of the quantitative impairment test involves a two-step process. The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. We generally determine the fair value of our reporting units using the income approach methodology of valuation that includes the discounted cash flow method as well as other generally accepted valuation methodologies. If the carrying amount of a reporting unit exceeds the reporting unit's fair value, we perform the second step of the quantitative impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit's goodwill with the carrying value of that goodwill. We acquired MicroProbe and performed a fair value assessment as of the acquisition date, October 16, 2012 resulting in our current goodwill balance. We will perform our annual goodwill impairment test in the fourth fiscal quarter.

Intangible Assets

Intangible assets consists of acquisition related intangible assets and intellectual property. The intangible assets are being amortized over periods which reflect the pattern in which economic benefits of the assets are expected to be realized, over 1 to 10 years, utilizing either an accelerated or straight-line basis of amortization. We perform a review of intangible assets when facts and circumstances indicate that the useful life is shorter than originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances exist, we assess the recoverability of identified intangible assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets.

Impairment of Long-Lived Assets

We test long-lived assets or asset groups for recoverability when events or changes in circumstances indicate that their carrying amounts may not be recoverable. Circumstances which could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the asset; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed of before the end of its estimated useful life.

Recoverability is assessed based on the carrying amounts of the asset and its fair value which is generally determined as the sum of the undiscounted cash flows expected to result from the use and the eventual disposal of the asset, as well as specific appraisals in certain instances. An impairment loss is recognized when the carrying amount is not recoverable and exceeds fair value.

We performed an enterprise-wide impairment test in the fourth fiscal quarter of 2012. No enterprise-wide impairment charges were recorded during fiscal 2012 and fiscal 2011. We recorded an enterprise-wide charge in 2010 of $52.0 million. See Note 7 - Impairment of Long-lived Assets for additional information.

Long-Lived Assets Held For Sale

We classify long-lived assets as held for sale when certain criteria are met, including: management's commitment to a plan to sell the assets; the availability of the assets for immediate sale in their present condition; whether an active program to locate buyers and other actions to sell the assets has been initiated; whether the sale of the assets is probable and their transfer is expected to qualify for recognition as a completed sale within one year; whether the assets are being marketed at reasonable prices in relation to their fair value; and whether it is unlikely that significant changes will be made to the plan to sell the assets.

We measure long-lived assets to be disposed of by sale at the lower of the carrying amount or fair value less cost to sell. Fair value is determined using quoted market prices or the anticipated cash flows discounted at a rate commensurate with the risk involved. Changes to our estimated fair values of such assets are recorded in the periods in which such changes are identified.

Concentration of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, marketable securities, trade receivables and derivative financial instruments used in hedging activities. Our cash equivalents and marketable securities are held in safekeeping by large, creditworthy financial institutions. We invest our excess cash primarily in U.S. banks, government and agency bonds, money market funds and corporate obligations. We have established guidelines relative to credit ratings, diversification and maturities that seek to maintain safety and liquidity. Deposits in these banks may exceed the amounts of insurance provided on such deposits. To date, we have not experienced any losses on our deposits of cash and cash equivalents.

We market and sell our products to a narrow base of customers and generally do not require collateral. In fiscal 2012, two customers accounted for 29% and 12% of revenues. In fiscal 2011, three customers accounted for 16%, 11% and 10% of revenues. In fiscal 2010, three customers accounted for 20%, 13%, and 12% of revenues.

At December 29, 2012, one customer accounted for 29% of accounts receivable. At December 31, 2011, two customers accounted for 12%, and 10% of accounts receivable. We operate in the intensely competitive semiconductor industry, including the DRAM, Flash, and System-on-Chip ("SoC") markets, which have been characterized by price erosion, rapid technological change, short product life, cyclical market patterns and heightened foreign and domestic competition. Significant technological changes in the industry could affect operating results adversely.

We are exposed to non-performance risk by counterparties on the currency forward exchange contracts used in hedging activities. We seek to minimize risk by diversifying our hedging program across multiple financial institutions. These counterparties are large international financial institutions, and to date no such counterparty has failed to meet its financial obligations to us.

Certain components that meet our requirements are available only from a limited number of suppliers. The rapid rate of technological change and the necessity of developing and manufacturing products with short lifecycles may intensify these risks. The inability to obtain components as required, or to develop alternative sources, if and as required in the future, could result in delays or reductions in product shipments, which in turn could have a material adverse effect on our business, financial condition, results of operations or cash flows.

Revenue Recognition

We recognize revenue when persuasive evidence of a sales arrangement exists, title and risk of loss has transferred to the customer, the selling price is fixed or determinable and collection of the related receivable is reasonably assured. In instances where final acceptance of the deliverable is specified by the customer, revenue is deferred until all acceptance criteria have been met.

In October 2009, the FASB issued Accounting Standards Update No. 2009-13, “Multiple-Deliverable Revenue Arrangements”. The guidance eliminates the residual method of revenue recognition and allows the use of management's best estimate of selling price (“BESP”) for individual elements of an arrangement when vendor-specific objective evidence (“VSOE”) or third-party evidence (“TPE”) is unavailable. We adopted this guidance effective with the first quarter of fiscal 2011 and it has been applied on a prospective basis for revenue arrangements entered into or materially modified after December 25, 2010.

This guidance does not generally change the units of accounting for our revenue transactions. We do not have a significant number of product offerings with multiple elements. Our multiple-element arrangements generally include probe cards and product maintenance and repair services. We allocate revenue to the deliverables based upon their relative selling price. Revenue allocated to each unit of accounting is then recognized when persuasive evidence of an arrangement exists, delivery has occurred or services are rendered, the sales price or fee is fixed or determinable and collectability is reasonably assured. Product maintenance and repair services are deferred and recognized ratably over the period during which the services are performed, generally one year, and costs are recorded as incurred.

When applying the relative selling price method, we determine the selling price for each deliverable using VSOE, TPE or BESP. For the vast majority of our arrangements involving multiple deliverables, such as sales of products with services, the entire fee from the arrangement was allocated to each respective element based on its relative selling price, using VSOE. For those deliverables for which we cannot establish VSOE, we have determined our best estimate of selling price, as the Company has determined it is unable to establish TPE of selling price for the deliverables. The objective of BESP is to determine the price at which we would transact a sale if the deliverable were sold on a stand-alone basis. We determine BESP for a deliverable by considering multiple factors including, but not limited to, market conditions, competitive landscape, internal costs, gross margin objectives and pricing practices. The determination of BESP is made through consultation with and formal approval by our management, taking into consideration the go-to-market strategy.

The adoption of the new revenue recognition accounting standards did not have a material impact on our consolidated financial position, results of operations, or cash flows for the year ended December 31, 2011. The new accounting standards for revenue recognition if applied in the same manner to the year ended December 25, 2010 would not have had a material impact on total net revenues for that fiscal year.

Revenues from the licensing of our design and manufacturing technology, which have not been material to date, are recognized over the term of the license agreement or when the significant contractual obligations have been fulfilled.

Warranty Obligations

We offer warranties on certain products and record a liability for the estimated future costs associated with warranty claims at the time revenue is recognized. The warranty liability is based upon historical experience and our estimate of the level of future costs. While we engage in product quality programs and processes, our warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. We continuously monitor product returns for warranty and maintain a reserve for the related expenses based upon our historical experience and any specifically identified field failures. As we sell new products to our customers, we must exercise considerable judgment in estimating the expected failure rates. This estimating process is based on historical experience of similar products, as well as various other assumptions that we believe to be reasonable under the circumstances.

We provide for the estimated cost of product warranties at the time revenue is recognized. Warranty costs are reflected in the Statement of Operations as a cost of revenues. A reconciliation of the changes in our warranty liability is as follows (in thousands):



	Fiscal Years Ended
	December 29, 2012			December 31, 2011
Warranty accrual beginning balance	$	330		$	433
Accrual of warranties during the year	1,744			666
Settlements made during the year	(1,340		)	(769		)
Warranty accrual ending balance	$	734		$	330

Research and Development

Research and development expenses include expenses related to product development, engineering and material costs. All research and development costs are expensed as incurred.

Allowance for Doubtful Accounts

A majority of our trade receivables are derived from sales to large multinational semiconductor manufacturers throughout the world. In order to monitor potential credit losses, we perform ongoing credit evaluations of our customers' financial condition. An allowance for doubtful accounts is maintained based upon our assessment of the expected collectability of all accounts receivable. The allowance for doubtful accounts is reviewed and assessed for adequacy on a quarterly basis. We take into consideration (1) any circumstances of which we are aware of a customer's inability to meet its financial obligations and (2) our judgments as to prevailing economic conditions in the industry and their impact on our customers. If circumstances change, and the financial condition of our customers are adversely affected and they are unable to meet their financial obligations to us, we may need to take additional allowances, which would result in an increase in our net loss.

The allowance for doubtful accounts consisted of the following activity for fiscal years 2012, 2011, and 2010 (in thousands):



	Balance at Beginning of Year		Additions		Reductions			Balance at End of Year
Allowance for doubtful accounts receivable
Fiscal year ended December 25, 2010	$	9,260	$	315	$	(8,728	)	$	847
Fiscal year ended December 31, 2011	847		29		(638		)	238
Fiscal year ended December 29, 2012	238		202		(151		)	289

A description of activity recorded in our allowance for doubtful accounts is as follows:

•

Fiscal 2010: we recorded an additional allowance for doubtful accounts of $0.3 million for accounts determined to be uncollectible and we released $8.7 million of allowance for doubtful accounts primarily due to a reduction of $6.7 million related to the dismissal of a complaint against a customer resulting in the write-off of previously reserved accounts receivable, a write-off of $0.5 million uncollectible debts that was previously reserved and receipt of payments totaling $1.4 million for accounts receivable that was previously reserved.


•	Fiscal 2011: we recorded a reduction in the provision of $0.6 million primarily due to the receipt of payments totaling $0.3 million for accounts receivable previously reserved and we wrote-off previously reserved accounts receivable in the amount of $0.3 million.


•	Fiscal 2012: we recorded a provision of $0.2 million and released $0.2 million of allowance for doubtful accounts that was previously reserved.

Restructuring Charges

Restructuring charges include costs related to employee termination benefits, long-lived assets impaired or abandoned, as well as contract termination costs. The determination of when we accrue for employee termination benefits depends on whether the termination benefits are provided under a one-time benefit arrangement or under an on-going benefit arrangement. For restructuring charges recorded as an on-going benefit arrangement, a liability for post-employment benefits is recorded when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated. For restructuring charges recorded as a one-time benefit arrangement, we recognize a liability for employee termination benefits when a plan of termination, approved by management and establishing the terms of the benefit arrangement, has been communicated to employees. The timing of the recognition of one-time employee termination benefits is dependent upon the period of time the employees are required to render service after communication. If employees are not required to render service in order to receive the termination benefits or if employees will not be retained to render service beyond the minimum legal notification period, a liability for the termination benefits is recognized at the communication date. In instances where employees will be retained to render service beyond the minimum legal notification period, the liability for employee termination benefits is measured initially at the communication date based on the fair value of the liability as of the termination date and is recognized ratably over the future service period. We continually evaluate the adequacy of the remaining liabilities under our restructuring initiatives.

We record charges related to long-lived assets to be abandoned when the assets cease to be used. When we cease using a building or other asset with remaining non-cancelable lease payments continuing beyond our use period, we record a liability for remaining payments under lease arrangements, as well as for contract termination costs, that will continue to be incurred under a contract for its remaining term without economic benefit to us at the cease-use date. Given the significance of, and the timing of the execution of such activities, this process is complex and involves periodic reassessments of estimates made at the time the original decisions were made, including evaluating real estate market conditions for expected vacancy periods and sub-lease rents. Although we believe that these estimates accurately reflect the costs of our restructuring plans, actual results may differ, thereby requiring us to record additional provisions or reverse a portion of such provisions.

The Company recorded restructuring charges of $2.9 million, $0.5 million and $15.9 million for fiscal years 2012, 2011 and 2010 respectively. See Note 5 Restructuring Charges.

Income Taxes

We utilize the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse and for operating losses and tax credit carryforwards. We estimate our provision for income taxes and amounts ultimately payable or recoverable in numerous tax jurisdictions around the world. Estimates involve interpretations of regulations and are inherently complex. Resolution of income tax treatments in individual jurisdictions may not be known for many years after completion of any fiscal year. We are required to evaluate the realizability of our deferred tax assets on an ongoing basis to determine whether there is a need for a valuation allowance with respect to such deferred tax assets. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. Significant management judgment is required in determining any valuation allowance recorded against deferred tax assets. In evaluating the ability to recover deferred tax assets, we consider all available positive and negative evidence giving greater weight to our recent cumulative losses and our ability to carryback losses against prior taxable income and, commensurate with objective verifiability, the forecast of future taxable income including the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies.

We recognize and measure uncertain tax positions taken or expected to be taken in a tax return if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. We report a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate, as well as the related net interest. We recognize interest and penalties related to unrecognized tax benefits within the income tax provision. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheet.

We file annual income tax returns in multiple taxing jurisdictions around the world. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, we believe that our reserves for income taxes reflect the most likely outcome. We adjust these reserves, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position could require the use of cash.

Stock-Based Compensation

We recognize compensation expense for all stock-based awards based on the grant-date estimated fair values, net of an estimated forfeiture rate. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods in our Consolidated Statement of Operations. The fair value of stock options is measured using the Black-Scholes option pricing model while the fair value for restricted stock awards and restricted stock units is measured based on the closing market price of our common stock on the date of grant.

Net Loss Per Share

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed giving effect to all potential dilutive common stock, including stock options, restricted stock units and common stock subject to repurchase. Diluted loss per share was based only on the weighted-average number of shares outstanding during that period as the inclusion of any common stock equivalents would have been anti-dilutive.

A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share is as follows (in thousands):



	Fiscal Years Ended

Accumulated Other Comprehensive Income

Accumulated other comprehensive income includes foreign currency translation adjustments and unrealized gains (losses) on available-for-sale securities net of tax, the impact of which has been excluded from earnings and reflected as components of stockholders' equity.

Components of accumulated other comprehensive income was as follows (in thousands):

Recent Accounting Pronouncements

Fair Value

Effective December 26, 2010, as required, we adopted the guidance to amend the disclosure requirements related to recurring and nonrecurring fair value measurements. Specifically, we have adopted the guidance requiring the disclosure of the roll forward of activities on purchases, sales, issuances and settlements of the assets and liabilities measured using significant unobservable inputs (Level 3 fair value measurements). Other than requiring additional disclosures, adoption of this new guidance in the first quarter of fiscal 2011 did not impact on our consolidated financial statements.

Additionally, in May 2011, updated authoritative guidance to amend existing requirements for fair value measurements and disclosures was issued. The guidance expands the disclosure requirements around fair value measurements categorized in Level 3 of the fair value hierarchy and requires disclosure of the level in the fair value hierarchy of items that are not measured at fair value but whose fair value must be disclosed. It also clarifies and expands upon existing requirements for fair value measurements of financial assets and liabilities as well as instruments classified in stockholders' equity. The guidance was effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and was applied prospectively. This new guidance impacts how we report on fair value measurements only, and had no effect on our results of operations, financial position or liquidity upon our adoption on January 1, 2012.

Comprehensive Income

In June 2011, authoritative guidance that addresses the presentation of comprehensive income in interim and annual reporting of financial statements was issued. The standard eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. Such changes in stockholders’ equity will be required to be disclosed in either a single continuous statement of comprehensive income or in two separate but consecutive statements. We have adopted this guidance effective with the first quarter of fiscal 2012 and such adoption did not have a material impact on our consolidated financial statements.

In February 2013, the FASB issued revised guidance on “Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” The revised guidance does not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the revised guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The revised guidance is effective prospectively for reporting periods beginning after December 15, 2012 for public entities. The revised guidance will not have a material effect on the Company's financial position, results of operations or liquidity

Acquisitions

Business Combinations [Abstract]

Acquisitions

Acquisition

On October 16, 2012, pursuant to an Agreement and Plan of Merger and Reorganization, or (the “Acquisition Agreement”), dated as of August 31, 2012, as amended, a wholly-owned subsidiary of FormFactor merged with and into Astria Semiconductor Holding, Inc., including its subsidiary MicroProbe, Inc. (together “MicroProbe”), with MicroProbe continuing as the surviving corporation and as a wholly-owned subsidiary of FormFactor (the "MicroProbe acquisition").

The Acquisition was accounted for using the acquisition method of accounting under which assets and liabilities of MicroProbe 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.

The total acquisition consideration of $113.8 million was determined based on the terms of the Acquisition Agreement which consisted of a) $100.0 million in cash, subject to a $3.3 million decrease based on MicroProbe's working capital as of the consummation of the Acquisition relative to an agreed upon target and b) 3,020,944 shares of FormFactor's common stock valued at the closing market price of $4.57 per share on October 16, 2012, and c) the fair value of a settlement related to patent litigation between the two parties of $3.3 million.

Pursuant to the Acquisition Agreement, $17.8 million of the cash consideration was placed in escrow (the "Holdback") for unknown liabilities that may have existed as of the acquisition date. The Holdback, which was included as part of the acquisition consideration, will be paid for such unknown liabilities or to the former MicroProbe shareholders within 18 months from the closing date of the Acquisition.

During fiscal 2012, we incurred $2.6 million in transaction costs related to the Acquisition, which primarily consisted of investment banking, legal, accounting and valuation-related expenses. These expenses were recorded in selling, general and administrative expense in the accompanying Consolidated Statements of Operations.

The acquisition price was allocated to the tangible and identified intangible assets acquired and liabilities assumed as of the closing date of the Acquisition based upon their respective fair values. Asset categories acquired in the Acquisition included working capital, long-term assets and liabilities and identifiable intangible assets, including in-process research and development (IPR&D). The allocation of the acquisition price has been prepared on a preliminary basis and changes to that allocation may occur as additional information becomes available. The table below summarizes the assets acquired and liabilities assumed as follows (in thousands):



	Amount
Cash and cash equivalents	$	2,847
Accounts receivable (1)	21,567
Inventories	11,809
Refundable income taxes	4,885
Prepaid assets	1,544
Deferred tax asset	756
Property, plant and equipment	11,950
Other long-term assets	103
Accounts payable and accrued expenses	(20,586		)
Capital leases	(1,025		)
Deferred income taxes liabilities	(26,663		)
Other long-term liabilities	(2,008		)
Total tangible assets acquired and liabilities assumed	5,179

Intangible assets	77,600
Goodwill	30,994
Total intangible and goodwill assets acquired	108,594

Total acquisition price	$	113,773


(1)	The estimated fair value of trade receivables acquired was $21.6 million. The gross contractual amount of trade receivables was $21.8 million and was recorded net of allowances for doubtful accounts. We expect that $0.2 million of the gross contractual amount of trade receivables will be uncollectible.

The intangible assets as of the closing date of the Acquisition included (in thousands):



	Amount
Existing developed technologies	$	31,100
Trade names	4,500
Customer relationships	17,000
Backlog	3,500
Favorable lease asset	300
Non-compete agreement	100
In-process research and development	21,100
Total intangible assets	$	77,600

Indications of fair value of the intangible assets acquired in connection with the Acquisition were determined using either the income, market or replacement cost methodologies. The intangible assets are being amortized over periods which reflect the pattern in which economic benefits of the assets are expected to be realized. The existing developed technologies are being amortized on an accelerated basis over an estimated useful life of one to four years; customer relationships are being amortized on an accelerated or straight-line basis over eight years depending on the product customer base; trade names and non-compete agreements are being amortized on a straight-line basis over ten years and one year, respectively; the favorable lease asset is being amortized on a straight-line basis over the term of the related lease; and the backlog is expected to be fully amortized by the second quarter of fiscal 2013.

The excess of purchase price over the fair value amounts assigned to the assets acquired and liabilities assumed represents the amount of goodwill resulting from the Acquisition. We do not expect any portion of this goodwill to be deductible for tax purposes. The goodwill attributable to the Acquisition has been recorded as a non-current asset and is not amortized, but is subject to an annual review for impairment. We believe the factors that contributed to goodwill include synergies that are specific to our consolidated business, the acquisition of a talented workforce that expands our expertise in business development and commercializing semiconductor test products as well as other intangible assets that do not qualify for separate recognition.

The results of operations of the MicroProbe business and the estimated fair values of the assets acquired and liabilities assumed have been included in our consolidated financial statements since the date of the Acquisition. Since the closing date of the Acquisition, the contribution of the acquired MicroProbe business to our total revenues and net loss were $19.8 million and $6.4 million, respectively.

Pro forma financial information (unaudited)

The following unaudited supplemental pro forma information presents the combined historical results of operations of FormFactor and MicroProbe for the fiscal years 2012 and 2011, as if the Acquisition had been completed at the beginning of fiscal 2011. The pro forma financial information includes adjustments to reflect one time charges and amortization of fair value adjustments in the appropriate pro forma periods as though the companies were combined as of the beginning of 2011. These adjustments include:


•	An increase in amortization expense of $6.8 million and $17.4 million for the fiscal years 2012 and 2011, respectively, related to the fair value of acquired identifiable intangible assets,


•	The exclusion of transaction-related expenses of $6.0 million for the fiscal year ended 2012,


•	The exclusion of other non-recurring expenses of $8.9 million and $2.7 million for the fiscal years 2012 and 2011, respectively, primarily related to the fair value step-up to acquired inventory, fair value adjustments related to a warrant liability of MicroProbe, provision for income taxes and litigation expenses incurred between the two parties regarding a patent litigation action.


•	Exclusion of the deferred tax asset valuation release in 2012 and reflecting the valuation release in 2011 as if the Acquisition had been completed in 2011.

The unaudited pro forma results do not assume any operating efficiencies as a result of the consolidation of operations (in thousands, except per share data):

Marketable Securities

Marketable securities at December 29, 2012 consisted of the following (in thousands):



	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. Treasury	$	43,490	$	97	$	—		$	43,587
Agency securities	49,896		63		(1		)	49,958
	$	93,386	$	160	$	(1	)	$	93,545

Marketable securities at December 31, 2011 consisted of the following (in thousands):



	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. Treasury	$	76,462	$	205	$	(4	)	$	76,663
Agency securities	78,921		102		(42		)	78,981
Commercial paper	1,998		—		—			1,998
	$	157,381	$	307	$	(46	)	$	157,642

We typically invest in highly-rated securities with low probabilities of default. Our investment policy requires investments to be rated single-A or better, limits the types of acceptable investments, concentration as to security holder and duration of the investment. The net unrealized losses on the Company's investments in fiscal 2012 and 2011, respectively, were caused primarily by changes in interest rates.

Our investment portfolio consists of both corporate and government securities that have a maximum maturity of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. All unrealized losses are due to changes in market interest rates, bond yields and/or credit ratings. We do not have a foreseeable need to liquidate the portfolio and anticipate recovering the full cost of the securities either as market conditions improve, or as the securities mature. Accordingly, we believe that the unrealized losses are not other-than-temporary. When evaluating the investments for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below the amortized cost basis, review of current market liquidity, interest rate risk, the financial condition of the issuer, as well as credit rating downgrades.

As of December 29, 2012, none of our investments had been in a continuous loss position for 12 months or more.

The contractual maturities of marketable securities as of December 29, 2012 and December 31, 2011 were as follows (in thousands):



	December 29, 2012				December 31, 2011
	Amortized Cost		Fair Value		Amortized Cost		Fair Value
Due in one year or less	$	33,407	$	33,500	$	52,524	$	52,586
Due in one year to five years	59,979		60,045		104,857		105,056
	$	93,386	$	93,545	$	157,381	$	157,642

Realized gains on sales or maturities of marketable securities were $1,422, $32,000 and $0.1 million for each of the fiscal years 2012, 2011, and 2010, respectively.

Asset Retirement Obligations

We account for the fair value of a liability for an asset retirement obligation to be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset and this additional carrying amount is amortized over the life of the asset. Our asset retirement obligation is associated with our commitment to return property subject to operating leases in Taiwan, South Korea, Singapore and Japan to their original condition upon lease termination. We have estimated that as of December 29, 2012, gross expected future cash flows of $1.3 million would be required to fulfill these obligations.

The carrying amount of the leasehold improvements resulting from asset retirement obligations is being amortized over the term of the related lease. Leasehold improvements amortization expense was zero for fiscal years 2012 and 2011, and was less than $0.1 million for fiscal 2010. During fiscal 2012 we updated our estimate for our asset retirement obligation in conjunction with the renewal of leases in certain locations. As a result, we recorded a benefit of $0.2 million due to the reduction in the estimated future required cash flows related to our obligations at these locations.

In connection with our Q3 2010 Restructuring Plan, we recorded impairment charges of $1.1 million to write down the carrying amount of leasehold improvements associated with asset retirement obligations in our Singapore manufacturing facility. This impairment charge was included within "Restructuring charges, net" in the Consolidated Statements of Operations for fiscal 2010. Subsequently, in fiscal 2011 we executed an amendment to the existing lease arrangement for our facility in Singapore which released us from our obligations related to the floor previously utilized for manufacturing in this facility. As a result, our Consolidated Statements of Operations for fiscal 2011 includes a benefit of $1.1 million recorded to "Restructuring charges, net".

The following is a reconciliation of the aggregate retirement liability associated with our commitment to return property to its original condition upon lease termination included in non-current "Deferred rent and other liabilities" in the Consolidated Balance Sheets (in thousands):

In fiscal 2012 and fiscal 2011, we wrote off fully depreciated assets with an acquired cost of $0.2 million and $0.6 million, respectively.

As discussed in Note 8 - Fair Value in fiscal 2011, a building previously identified as held for sale, was returned into service at its carrying value of $0.8 million. This amount represents the lesser of its carrying amount before the building was classified as held for sale, adjusted for any depreciation that would have been recognized had the building been continuously classified as held and used, or the fair value at the date of the subsequent decision not to sell. The building is being depreciated over its estimated remaining useful life of ten years.

As discussed in Note 7 - Impairment of Long-lived Assets in fiscal 2012 and 2011, we recorded aggregated impairment charges of $0.4 million and $0.5 million in our long lived assets, respectively. In fiscal 2010, we recorded aggregated impairment charges of $56.4 million, including $55.3 million and $1.1 million to write down the carrying values of certain property and equipment and intangible assets, respectively.

Depreciation and amortization of property, plant and equipment, excluding the impairments charges discussed above, for the fiscal years 2012, 2011 and 2010 was $10.3 million, $10.8 million and $26.4 million, respectively.

Accrued Liabilities

	$	17,270	$	13,966

In November 2009, we sold all rights, title and interest in a customer's bankruptcy claim to a third party in exchange for net proceeds of less than full value of the asserted claim. The proceeds were accounted for as a secured borrowing and included as an accrued liability. On October 8, 2010, we voluntarily dismissed our complaint against this customer. As a result, we released the amounts previously recorded as a secured borrowing and recorded a gain of $3.5 million in "Other income, net" in the Consolidated Statement of Operations in fiscal 2010.

In fiscal 2010, we ceased the utilization of one facility in Livermore and our facility in Singapore that was expected to be utilized for our manufacturing operations. In connection with these decisions, we accrued liabilities totaling $0.7 million composed of the remaining lease obligations that will continue to be incurred under operating lease contracts of the Livermore and Singapore facilities of $0.3 million and $0.4 million, respectively. The charge relating to our Singapore facility of $0.4 million was recorded as additional restructuring charges in connection with our Q3 2010 Restructuring Plan, as discussed in Note 5—Restructuring Charges. Subsequently, in fiscal 2011 we executed an amendment to the existing lease arrangement for our facility in Singapore which released us from our obligations related to the space previously utilized for manufacturing in this facility. As a result, our Consolidated Statement of Operations for fiscal 2011 includes a benefit of $0.4 million recorded to "Restructuring charges, net", reflecting the reduction in the remaining liability as of the date of the newly executed arrangement.

Restructuring Charges

12 Months Ended

Dec. 29, 2012

We have undertaken several restructuring actions during fiscal 2012, 2011, and 2010, the purpose of which were to improve operating efficiency, streamline and simplify our operations and reduce our operating costs. These actions are discussed below:

2010 Restructuring Activities

We recorded $3.4 million in restructuring charges during the first quarter of fiscal 2010 as part of our then-current regionalization strategy (the “Q1 2010 Restructuring Plan”). These charges consisted of termination benefits related to reductions in work force of 106 full-time positions, which were all related to severance and related benefits. The activities related to this action were completed during fiscal 2011. Subsequently, in the second quarter of fiscal 2010 we undertook a plan to rescind the previously issued severance arrangements for certain employees impacted by this plan, resulting in the reversal of $3.3 million of the accrual for severance costs booked in conjunction with the Q1 2010 Restructuring Plan, including the accrued retention bonus to date. We completed this rescission plan in fiscal 2010.

In the second quarter of fiscal 2010, we announced a series of corporate initiatives, including a reduction in workforce, which represented a renewed focus on streamlining and simplifying our operations as well as reducing our quarterly operating costs (the “Q2 2010 Restructuring Plan”). These actions included a reduction in workforce impacting 67 employees spread across all functions of the organization, as well as a reduction in the scope of the previously contemplated manufacturing operations in Korea, resulting in a reduction of workforce of 16 employees related to the assembly and test function. We recorded $4.8 million in charges for the Q2 2010 Restructuring Plan during fiscal 2010, primarily for severance and related benefits. Additionally, in conjunction with the Q2 2010 Restructuring Plan we identified certain equipment and software assets related to our assembly and test operations in Korea that would no longer be utilized. As a result, we recorded impairment charges of $1.0 million in the fiscal 2010, representing the net book value of these assets.

In the third quarter of fiscal 2010, we announced a restructuring plan (the “Q3 2010 Restructuring Plan”) to cease the transition of manufacturing operations to Singapore. This decision resulted in a reduction in force of 58 employees at our Singapore facility. The manufacturing activities that were scheduled to be transitioned to Singapore remained in Livermore, and Livermore continued as the primary manufacturing operating location for the Company. In conjunction with the Q3 2010 Restructuring Plan, we also undertook a reduction in force that involved two additional individuals in our Livermore operations.

We recorded charges of $1.0 million for severance and related benefits and impairment charges of $7.8 million for certain equipment and leasehold improvements, including assets related to asset retirement obligations, in Singapore that would no longer be utilized as a result of the Q3 2010 Restructuring Plan. This impairment was composed primarily of $5.8 million for leasehold improvements, $0.6 million for manufacturing equipment and $0.6 million for software and system assets related to the manufacturing operations that will be taken out of service or abandoned, as well as $0.8 million to adjust the carrying amount of certain equipment determined to be held for sale. In addition, due to the combined effect of the significant change in our business strategy in connection with the Q3 2010 Restructuring Plan, recurring operating losses and the sustained decline in the Company's stock price, we reviewed the recoverability of our long-lived assets in the third quarter of fiscal 2010, as discussed in Note 7-Impairment of Long-lived Assets of the Notes to the Consolidated Financial Statements.

In the fourth quarter of fiscal 2010, we implemented a restructuring plan (the "Q4 2010 Restructuring Plan") including reducing our global workforce by 10 employees across the organization. We recorded $0.6 million in charges for severance and related benefits in fiscal 2010.

The ending restructuring accrual of $1.8 million as of December 25, 2010 reflects the unpaid amounts related to these actions as of that date. Unless otherwise noted, the activities comprising the above reductions in force were completed by the end of fiscal 2011.

2011 Restructuring Activities

In the first quarter of fiscal 2011, we implemented a restructuring plan (the “Q1 2011 Restructuring Plan”) which resulted in the reduction of our global workforce by 13 full-time employees across the organization. We recorded $1.1 million in charges for severance and related benefits related to this plan. The activities comprising this reduction in workforce were substantially completed by the end of the second quarter of fiscal 2011. As a result of the Q1 2011 Restructuring Plan, we have realized, and expect to continue to realize, quarterly savings, excluding stock-based compensation expenses, of approximately $0.6 million in subsequent quarters.

In the second quarter of fiscal 2011, we implemented a restructuring plan (the “Q2 2011 Restructuring Plan”) which resulted in the reduction of our global workforce by 13 full-time employees across the organization. We recorded $0.6 million in charges for severance and related benefits related to this plan. The activities comprising this reduction in workforce were substantially completed by the end of the third quarter of fiscal 2011. As a result of the Q2 2011 Restructuring Plan we have realized, and expect to continue to realize, quarterly savings, excluding stock-based compensation expenses, of approximately $0.4 million in subsequent quarters.

Additionally, in the second quarter of fiscal 2011 we executed an amendment to the existing lease arrangement for our facility in Singapore which released us from our obligations related to the space previously utilized for manufacturing in this facility. We were also granted a rent reduction for the remaining occupied facilities in this building. We had previously recorded certain asset retirement obligations of $1.1 million (see Note 4 - Balance Sheet Components) and accruals related to our cessation of the use of these facilities in connection with a prior restructuring action of $0.4 million. As a result, our Consolidated Statement of Operations for fiscal 2011 includes a benefit of $1.5 million recorded to "Restructuring charges, net".

In the third quarter of fiscal 2011, we implemented a restructuring plan (the “Q3 2011 Restructuring Plan”) which resulted in the reduction of our global workforce by four full-time employees primarily in our procurement and logistics organizations. We recorded $0.3 million in charges for severance and related benefits related to this plan. The activities comprising this plan were completed during fiscal 2011. As a result of the Q3 2011 Restructuring Plan, we have realized quarterly savings, excluding stock-based compensation expenses, of approximately $0.2 million in subsequent quarters.

In the fourth quarter of fiscal 2011, we implemented a restructuring plan (the “Q4 2011 Restructuring Plan”) which resulted in the reduction of our global workforce by eight full-time employees primarily in our finance and procurement and logistics organizations. We recorded $0.3 million in charges for severance and related benefits related to this plan. The activities comprising this reduction were completed in fiscal 2012. As a result of the Q4 2011 Restructuring Plan, we have realized quarterly savings, excluding stock-based compensation expenses, of approximately $0.3 million in subsequent quarters.

2012 Restructuring Activities

In the second fiscal quarter of 2012, we recorded $0.1 million in charges for severance and related benefits related to restructuring activities. This resulted in the reduction of our global workforce by 1 employee across the organization. The activities comprising this restructuring activity were completed in fiscal 2012.

In the third fiscal quarter of 2012, we implemented a restructuring plan (the "Q3 2012 Restructuring Plan") which resulted in the reduction of our global workforce by 44 employees across the organization. In conjunction with this action, we also initiated a plan to cease our assembly and test manufacturing operations in Japan. We recorded $1.8 million in severance and related benefits, $0.2 million in charges for contract termination, and other costs related to restructuring activities during the quarter related to this plan, and $0.4 million in impairment charges for certain equipment and leasehold improvements that would no longer be utilized. The activities comprising this reduction in workforce were completed by the end of fiscal 2012. As a result of the Q3 2012 Restructuring Plan, we have realized quarterly savings, excluding stock-based compensation, of approximately $2.6 million in subsequent quarters.

In the fourth fiscal quarter of 2012, we implemented a restructuring plan (the "Q4 2012 Restructuring Plan") which resulted in the reduction of our global workforce by 4 employees across the organization. We recorded $0.4 million in severance and related benefits related to restructuring activities. The activities comprising this reduction in workforce are expected to be substantially completed by the end of the first quarter of fiscal 2013. As a result of the Q4 2012 Restructuring Plan, we have realized quarterly savings, excluding stock-based compensation, of approximately $0.1 million in subsequent quarters.

The following table summarizes the activities related to the restructuring actions of fiscal 2010 to 2012 (in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

We operate and sell our products in various global markets. As a result, we are exposed to changes in foreign currency exchange rates. We utilize foreign currency forward contracts to hedge against future movements in foreign exchange rates that affect certain existing foreign currency denominated assets and liabilities. Under this program, our strategy is to have increases or decreases in our foreign currency exposures offset by gains or losses on the foreign currency forward contracts to mitigate the risks and volatility associated with foreign currency transaction gains or losses. We do not use derivative financial instruments for speculative or trading purposes. Our derivative instruments, which are generally settled in the same quarter, are not designated as hedging instruments.

Impairment of Long-lived Assets

The following table summarizes the components of the impairments that we recorded in fiscal 2012, 2011 and 2010 (in thousands):



	Fiscal Years Ended
	December 29, 2012		December 31, 2011		December 25, 2010
Impairment of long-lived assets:
Assets held for sale	$	168	$	—	$	342

Intangible assets	—		—		1,082
Enterprise-wide impairment	—		—		52,021
Total	$	421	$	549	$	56,401

Assets held for sale

In fiscal 2012, we recorded a $0.2 million charge related to certain assets which were previously held for sale that were determined to be no longer saleable and used for internal purposes.

In fiscal 2011, we did not record impairment charges related to our assets held for sale.

In fiscal 2010, we recorded aggregated impairment charges of $0.3 million in conjunction with the write down of a building held for sale to its estimated fair value and certain furniture and fixtures at our Livermore facility that were determined to be held for sale.

These impairments were included within "Impairment of long-lived assets" in the Consolidated Statement of Operations for their respective periods.

Assets to be disposed of other than by sale

In fiscal 2012, we recorded $0.2 million related to the termination of on-going construction-in-progress projects.

During fiscal 2011, we recorded impairment charges totaling $0.5 million related to certain assets to be disposed of other than by sale, all of which related to the termination of certain on-going projects that had been recorded in construction-in-progress, including aspects of certain software development for internal use.

During fiscal 2010, we recorded impairment charges totaling $3.0 million related to certain assets to be disposed of other than by sale. These charges were composed of $2.7 million related to the termination of on-going construction-in progress projects, including those related to certain projects for the development and build of manufacturing equipment, as well as additional equipment that was in-service and identified as excess capacity. Additionally, these charges included $0.3 million related to certain leasehold improvements that were abandoned as a result of the consolidation of office space in Livermore.

All of these charges are included in "Impairment of long-lived assets" in the Consolidated Statements of Operations for their respective periods.

Intangible assets

We did not record impairment charges related to our intangible assets during fiscal 2012 and 2011.

During fiscal 2010, our renewed focus on simplifying and refocusing our operations on our core competencies resulted in our decision to reduce efforts to license and market software underlying certain intangible assets that were acquired in conjunction with our acquisition of certain assets from Electroglas, Inc. in 2010 through a bankruptcy proceeding. As a result, we performed an impairment analysis of these purchased intangible assets during the third quarter of fiscal 2010 and recorded an impairment charge of $1.1 million for the carrying amount of the impaired assets. The impairment charge was included in "Impairment of long-lived assets" in the Consolidated Statements of Operations in fiscal 2010.

Enterprise-wide impairment

At the end of the third quarter of fiscal 2010, in addition to the specific impairments discussed above, we determined that an enterprise-wide impairment analysis of our long-lived assets was required due to the combined effect of a sustained decline in the Company's stock price, a significant change in our business strategy in connection with the Q3 2010 Restructuring Plan, and recurring operating losses and net cash outflows from operations. Accordingly, management reviewed the recoverability of its long-lived assets in the third quarter of fiscal 2010.

We determined our long-lived asset group to be our consolidated long-lived assets as we had determined that we operate as one reporting unit and segment. This asset group included property and equipment, as well as purchased intangible assets. The recoverability of assets to be held and used was measured by comparing the carrying amount of these assets, after adjustment for the various specific impairments discussed above, to the estimated undiscounted future cash flows expected to be generated by the assets. If the carrying amount of the asset exceeds its estimated undiscounted future net cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.

As a result, we concluded that our business was not able to fully recover the carrying amount of our assets. Accordingly, we reviewed the carrying amounts at September 25, 2010 of all of our long-lived assets for impairment. The review involved estimating the fair value in an exchange transaction of our asset group, comparing such fair value to the carrying amount of the asset group, after adjustment for the various specific impairments discussed above, and recording impairment charges to reduce the pre-impairment carrying amount of the asset group to its estimated fair value.

Determining the fair value of an asset group unit is judgmental in nature and requires the use of significant estimates and assumptions, including current replacement costs, revenue growth rates and operating margins, and discount rates, among others. Accordingly, we were required to make various estimates in determining the fair values of our asset group at September 25, 2010. Where appropriate, we utilized a market approach to estimate the fair value of our property and equipment. This approach included the identification of market prices in actual transactions for similar assets based on asking prices for assets currently available for sale, as well as obtaining and reviewing certain direct market values based quoted prices with manufacturers and secondary market participants for similar equipment. However, due to the highly customized nature of our manufacturing equipment we primarily utilized the cost approach to estimate the fair value of our property and equipment. To determine the estimated fair value of our property and equipment at September 25, 2010, adjustment factors, including cost trend factors, were applied to each individual asset's original cost in order to estimate current replacement cost. The current replacement cost was then adjusted for estimated deductions to recognize the effects of deterioration and obsolescence from all causes, as well as indirect costs such as installation.

The estimated fair value of the purchased intangible assets was determined based on a combination of two income-based approaches, as this combination was deemed to be the most indicative of the Company's fair value in an orderly transaction between market participants. Under these two income approaches we determined fair value based on both the estimated future cash flows resulting from the licensing of the technology underlying the intangible asset, as well as the estimated future cash savings achieved due to the avoidance of costs resulting from the internal use of the underlying technology. The estimated cash flows in each approach were discounted by an estimated weighted-average cost of capital which reflects the overall level of inherent risk of the enterprise and the rate of return an outside investor would expect to earn.

For each asset, we then compared the estimated fair value to the individual asset's carrying amount to determine the amount of the impairment charge. Based on this analysis, we recorded an impairment charge of $52.0 million in the third quarter of fiscal 2010. This charge, which was included in "Impairment of long-lived assets" in the Consolidated Statements of Operations, was comprised of $27.7 million for leasehold improvements, $11.2 million for manufacturing equipment, $8.5 million for computer equipment and software, $4.4 million for construction-in-progress and $0.2 million for purchased intangible assets.

Fair Value Disclosures [Abstract]

Fair Value

We use fair value measurements to record fair value adjustments to certain financial and non-financial assets and to determine fair value disclosures. The carrying amounts of certain of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, accrued compensation and other accrued liabilities, approximate fair value because of their short maturities. Our marketable securities are financial assets recorded at fair value on a recurring basis.

The accounting standards define fair value, establish a framework for measuring fair value in generally accepted accounting principles, and require disclosures about fair value measurements. Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. The accounting standard for fair value establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The standard describes a fair value hierarchy based on three levels of inputs, the first two of which are considered observable and the last unobservable, that may be used to measure fair value:


•	Level 1—Quoted prices in active markets for identical assets or liabilities.


•	Level 2—Inputs, other than the quoted prices in active markets, such as quoted prices for similar assets or liabilities, quoted prices near the reporting date in markets that are less active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.


•	Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

We utilize the market approach to measure the fair value of our fixed income securities. The market approach is a valuation technique that uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The fair value of our fixed income securities is obtained using readily-available market prices from a variety of industry standard data providers, large financial institutions, and other third-party sources for the identical underlying securities.

We obtain the fair value of our Level 1 investments in certain money market funds, which are expected to maintain a Net Asset Value of $1 per share, at the expected market price.

We obtain the fair value of our Level 2 financial instruments from several third party asset managers, custodian banks, and the accounting service providers. Independently, these service providers use professional pricing services to gather pricing data, which may include quoted market prices for identical or comparable instruments or inputs other than quoted prices that are observable either directly or indirectly.

Assets Measured at Fair Value on a Recurring Basis

We measure and report certain assets and liabilities at fair value on a recurring basis, including money market funds, U.S. government securities, agency securities, commercial papers and foreign currency derivatives. The following tables represent the fair value hierarchy for our financial assets (cash equivalents and marketable securities):

Fair value measured on a recurring basis as of December 29, 2012 (in thousands):



	Level 1		Level 2		Total
	(In thousands)
Cash equivalents
Money market funds	$	54,732	$	—	$	54,732
Marketable securities
U. S. treasury	—		43,587		43,587
Agency securities	—		49,958		49,958
	$	54,732	$	93,545	$	148,277

Fair value measured on a recurring basis as of December 31, 2011 (in thousands):



	Level 1		Level 2		Total
	(In thousands)
Cash equivalents
Money market funds	$	106,147	$	—	$	106,147
Commercial paper	—		8,999		8,999
Marketable securities
U. S. treasury	—		76,663		76,663
Agency securities	—		78,981		78,981
Commercial paper	—		1,998		1,998
	$	106,147	$	166,641	$	272,788

The Level 1 assets consist of our money market fund deposits. The Level 2 assets consist of our available-for-sale investment portfolio, which are valued utilizing a market approach. Our investments are priced by pricing vendors who provided observable inputs for their pricing without applying significant judgments. Broker's pricing is used mainly when a quoted price is not available, the investment is not priced by our pricing vendors or when a broker price is more reflective of fair values in the market in which the investment trades. Our broker-priced investments are labeled as Level 2 investments because fair values of these investments are based on similar assets without applying significant judgments. In addition, all of our investments have a sufficient level of trading volume to demonstrate that the fair values used are appropriate for these investments.

We did not have any transfers of assets measured at fair value on a recurring basis to or from Level 1 and Level 2 during fiscal 2012 and 2011.

Assets Measured at Fair Value on a Nonrecurring Basis

The following table represents the fair value hierarchy for our long-lived assets measured at fair value on a nonrecurring basis at their respective measurement dates (in thousands) at December 29, 2012:



	Level 3			Total Losses Fiscal 2012
Long-lived assets held for sale at December 31, 2011	$	389		$	—
Equipment impairment	(168		)	(168		)
Equipment returned to held and used	(155		)	—
Equipment sold	(66		)	—
Long-lived assets held for sale at December 29, 2012	$	—		$	(168	)

During fiscal 2012, equipment with a carrying value of $0.2 million was determined to be unusable and was written-off, $0.2 million of equipment was returned to held and used, and less than $0.1 million of equipment was sold.

At the end of fiscal 2010, we reflected a building in Livermore, California as held for sale, which was classified as a Level 2 asset because the estimated fair value of the building was determined using inputs developed from market data sources independent of us, that reflected the assumptions market participants would use in pricing the building. During fiscal 2011, this building was returned into service at its carrying value of $0.8 million, resulting in a reclassification of the balance from 'Prepaid expenses and other current assets' to 'Property, plant and equipment, net' in the Consolidated Balance Sheet. See Note 4 - Balance Sheets Components for more information.

Other than the building previously held for sale that was returned to service during 2011, we did not have any assets measured at fair value on a nonrecurring basis that were transferred to or from Level 2 or 3 during fiscal 2012 or 2011.

Our fair value processes include controls that are designed to ensure appropriate fair values are recorded. Such controls include model validation, review of key model inputs, and analysis of period-over-period fluctuations and independent recalculation of prices.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

The in-process research and development (“IPR&D”) intangible assets are classified as indefinite lived assets that are not currently subject to amortization but are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The IPR&D assets will be subject to amortization upon completion of their respective research projects and commercialization begins. The fair value assigned to IPR&D assets was determined using the income approach based on estimates and judgments regarding risks inherent in the development process, including the likelihood of achieving technological success and market acceptance. If an IPR&D project is abandoned, the acquired technology attributable to the project will be written-off.

We recorded $6.6 million, $1.2 million, and $1.7 million, in amortization expense related to our intangible assets in fiscal 2012, 2011, and 2010, respectively. Of the total amortization expense for fiscal 2012, 2011, and 2010, $6.0 million, $1.2 million, and $1.3 million were charged to cost of revenues, respectively, and $0.6 million, zero, and $0.4 million were charged to selling, general and administrative expense, respectively. Based on the carrying value of the finite-lived intangible assets recorded as of December 29, 2012, and assuming no subsequent additions to or impairment of the underlying assets, the remaining estimated annual amortization expense is expected to be as follows (in thousands):

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Leases

We lease facilities under non-cancellable operating leases with various expiration dates through 2021. The facilities generally require us to pay property taxes, insurance and maintenance costs. Further, several lease agreements contain rent escalation clauses or rent holidays. For purposes of recognizing minimum rental expenses on a straight-line basis over the terms of the leases, we use the date of initial possession to begin amortization. We have the option to extend or renew most of our leases which may increase the future minimum lease commitments.

Rent expense for the fiscal years 2012, 2011, and 2010, was $4.7 million, $4.8 million and $5.4 million, respectively.

We lease certain equipment under capital leases. The cost and accumulated depreciation for assets under capital leases, which were included in property, plant and equipment in the accompanying Consolidated Balance Sheets are as follows (in thousands):



	Fiscal Years Ended

Cost	$	2,367	$	—
Accumulated depreciation	255		—
Net book value	$	2,112	$	—

The depreciation expense of these leased assets was $0.2 million in fiscal 2012 and zero for both fiscal 2011 and 2010, respectively.

Future minimum payments under capital leases and non-cancelable operating leases are as follows as of December 29, 2012 (in thousands):



	Capital Leases			Operating Leases

Present value of capital lease amounts	913
Less: current portion	(573		)
Non-current portion	$	340

The current and non-current portions of the capital lease obligations are included in the accompanying Consolidated Balance Sheets.

Other Contractual Obligations

The following table sets forth our commitments to settle other contractual obligations in cash as of December 29, 2012:



	Payments Due In Fiscal Years
	2013		2014-2015		2016-2017		After 2017		Total
	(In thousands)
Purchase obligations	$	12,402	$	4,950	$	50	$	—	$	17,402

Other purchase obligations are primarily for purchases of inventory and manufacturing related service contracts. For the purposes of this table, other purchase obligations are defined as agreements that are enforceable and legally binding and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. The expected timing of payment of the obligations discussed above is estimated based on information available to us as of December 29, 2012. Timing of payments and actual amounts paid may be different depending on the time of receipt of goods or services or changes to agreed-upon amounts for some obligations.

The table above excludes our gross liability for unrecognized tax benefits, which totaled $17.2 million as of December 29, 2012 and are classified in deferred taxes and other long-term tax liabilities on our consolidated balance sheet. The timing of any payments which could result from these unrecognized tax benefits will depend upon a number of factors. Accordingly, the timing of payment cannot be estimated and has been excluded from the table above. As of December 29, 2012, the changes to our uncertain tax positions in the next 12 months, that are reasonably possible, are not expected to have a significant impact on our financial position or results of operations.

Indemnification Arrangements

We may, from time to time in the ordinary course of our business enter into contractual arrangements with third parties that include indemnification obligations. Under these contractual arrangements, we have agreed to defend, indemnify and/or hold the third party harmless from and against certain liabilities. These arrangements include indemnities in favor of customers in the event that our wafer probe cards infringe a third party's intellectual property and indemnities in favor of our lessors in connection with facility leasehold liabilities that we may cause. In addition, we have entered into indemnification agreements with our directors and certain of our officers, and our bylaws contain indemnification obligations in favor of our directors, officers and agents. These indemnity arrangements may limit the type of the claim, the total amount that we can be required to be paid in connection with the indemnification obligation and the time within which an indemnification claim can be made. The duration of the indemnification obligation may vary, and for most arrangements, survives the agreement term and is indefinite. We believe that substantially all of our indemnity arrangements provide either for limitations on the maximum potential future payments we could be obligated to make, or for limitations on the types of claims and damages we could be obligated to indemnify, or both. However, it is not possible to determine or reasonably estimate the maximum potential amount of future payments under these indemnification obligations due to the varying terms of such obligations, a lack of history of prior indemnification claims, the unique facts and circumstances involved in each particular contractual arrangement and in each potential future claim for indemnification, and the contingency of any potential liabilities upon the occurrence of events that are not reasonably determinable. We have not had any requests for indemnification under these arrangements. Our management believes that any liability for these indemnity arrangements would not be material to our accompanying consolidated financial statements. We have not recorded any liabilities for these indemnification arrangements on our consolidated balance sheet as of December 29, 2012.

Legal Matters

From time to time, we may be subject to legal proceedings and claims in the ordinary course of business. As of the filing of this Annual Report on Form 10-K, we were not involved in any material legal proceedings, other than the proceedings summarized below. In the future we may become a party to additional legal proceedings that may require us to spend significant resources, including proceedings designed to protect our intellectual property rights and to collect past due accounts receivable from our customers.

Customs and Trade Matters

From time to time, we receive communications from certain jurisdictions regarding customs and indirect tax matters such as customs duties and value added taxes. In fiscal 2011, we received inquiries from a foreign jurisdiction tax authority regarding certain indirect tax matters. We cooperated with these inquiries, which related to our prior shipping process for new product qualifications and for products for certain of our repair center activities. During fiscal 2011, we accrued $1.0 million for potential exposures related to these tax and customs matters. During the third quarter of 2012, we received what we believe are final communications on these tax and customs matters indicating we owed $0.3 million of unpaid indirect taxes and penalties. In the fourth quarter of fiscal 2012, we adjusted our accrual to reflect this final conclusion.

Patent Litigation

In July 2010, we filed a lawsuit in the United States District Court for the Northern District of California, case no. 4:10-cv-03095-PJH (the "Action"), against MicroProbe Inc. and a MicroProbe officer who was a former FormFactor employee. In the Action, we asserted patent infringement and unfair competition claims against MicroProbe, and trade secret misappropriation and breach of confidence claims against MicroProbe and the former FormFactor employee. On October 16, 2012, and in connection with an Agreement and Plan of Merger dated August 31, 2012, under which we acquired 100% of the outstanding shares of Astria Semiconductor Holdings, Inc. and its subsidiaries, see Note 3 Acquisitions for further information, FormFactor, Astria Semiconductor Holdings, MicroProbe, and a former FormFactor employee entered into a Confidential Settlement Agreement and these parties along with certain other entities entered into a Confidential Release Agreement, both to resolve the Action in favor of FormFactor for $3.3 million.

One or more third parties have initiated challenges in the U.S. Patent and Trademark Office, or USPTO, against certain of our patents, including requests for reexamination directed to all of the patents-in-suit in the Action. The USPTO granted the re-examination requests directed to U.S. Patent Nos. 6,246,247, 6,825,422, 6,441,315, and 7,225,538, and granted in part the requests directed to U.S. Patent Nos. 6,965,244, 7,227,371 and 7,671,614. Requests for reexamination of the Company's U.S. Patent Nos. 6,615,485 and 6,624,648 and 5,994,152 were also granted by the USPTO. With respect to US Patent No. 5,994,152, the re-examination proceeding has concluded and a re-examination certificate was issued. With respect to US Patent No. 6,624,648, the reexamination proceeding has concluded and a re-examination certificate was issued February 28, 2012. The Company did not appeal the adverse USPTO decision regarding US Patent No. 6,615,485. The foreign actions include proceedings in Taiwan against several of our Taiwan patents.

No provision has been made for patent-related litigation because we believe that it is not probable that a liability had been incurred as of December 29, 2012. We will incur material attorneys' fees in prosecuting and defending the various identified actions

Stockholders' Equity Note [Abstract]

Stockholders' Equity

12 Months Ended

Dec. 29, 2012

Stockholders' Equity

Preferred Stock

We have authorized 10,000,000 shares of undesignated preferred stock, $0.001 par value, none of which is issued and outstanding. Our Board of Directors shall determine the rights, preferences, privileges and restrictions of the preferred stock, including dividends rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of any series.

Common Stock

Each share of common stock has the right to one vote. The holders of common stock are also entitled to receive dividends whenever funds are legally available and when declared by the Board of Directors, subject to the prior rights of holders of all classes of stock outstanding having priority rights as to dividends. No dividends have been declared or paid as of December 29, 2012.

Common Stock Repurchase Program

On October 20, 2010, our Board of Directors authorized a program to repurchase up to $50.0 million of outstanding common stock. Under the authorized stock repurchase program, we were authorized to repurchase shares from time to time on the open market; the pace of repurchase activity depended on levels of cash generation, current stock price, and other factors. The stock repurchase program was announced on October 26, 2010 and had a scheduled expiration of October 19, 2011. The program could have been modified or discontinued at any time.

On October 12, 2011, our Board of Directors authorized the extension of this repurchase program through October 19, 2012. Under the program, we were authorized to repurchase up to a total of $40.5 million of outstanding common stock during the program period. The terms and conditions of the extended repurchase program remained the same as those in the original program approved in fiscal 2010. All of our repurchases were made under the authorized repurchase program.

During fiscal year 2010, we repurchased and retired 70,000 shares of common stock at a cost of $0.6 million. During fiscal 2011, we repurchased and retired 2,332,740 shares of common stock for $16.4 million. We did not repurchase any shares of common stock under the program during fiscal 2012.

Repurchased shares are retired upon the settlement of the related trade transactions. Our policy related to repurchases of our common stock is to charge the excess of cost over par value to additional paid-in capital. All repurchases were made in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.

The repurchase program ended effective October 19, 2012 and was not extended.

Equity Incentive Plans

During the fiscal quarter ended March 31, 2012 we had four equity incentive plans for which we have reserved shares for issuance upon the exercise of stock options: the 1996 Stock Option Plan, the Incentive Option Plan and the Management Incentive Option Plan (together, the “Prior Plans”), and the 2002 Equity Incentive Plan (the “2002 Plan”), which became effective in April 2002.

At our Annual Meeting of Stockholders on April 18, 2012 (the "2012 Annual Meeting"), our stockholders approved an amended and restated Equity Incentive Plan (the "2012 Plan"), reserving 7.4 million shares for future grants, less any shares granted between February 28, 2012 and April 18, 2012. In addition, shares underlying any outstanding stock award or stock option grant previously awarded under the Prior Plans and the 2002 Plan canceled or forfeited prior to vesting or exercise become available for use under the 2012 Plan. The 2002 Plan was terminated on April 18, 2012, except for outstanding awards. Upon the effectiveness of the 2012 Plan, we ceased granting any equity awards under the 2002 Plan. Subsequent awards have been and will be granted under the 2012 Plan.

The 2012 Plan provides for the grant of incentive stock options and nonqualified stock options, stock appreciation rights, restricted stock and restricted stock units. The incentive stock options may be granted to our employees and the nonqualified stock options, and all awards other than incentive stock options may be granted to employees, directors and consultants. The exercise price of incentive stock options must be at least equal to the fair market value of common stock on the date of grant. All options granted under the 2012 Plan will generally vest over four years and have a term of ten years, unless otherwise determined by the Compensation Committee of the Board of Directors. Stock appreciation rights, restricted stock and restricted stock units granted under the 2012 Plan will generally vest over four years in annual tranches. Additionally, restricted shares reduce the shares available for issuance at 1.55 shares for every one share issued.

At December 29, 2012, there were 6.5 million shares available for grant under the 2012 Plan.

Stock Options

Stock option activity under our equity plans is set forth below:

(1)	Options granted in fiscal 2010 included 679,864 shares of re-granted stock options with an exercise price of $8.61 per share as a result of our stock option exchange program effective October 1, 2010.


(2)	Options canceled in fiscal 2010 included 2,779,782 shares with a weighted average exercise price of $29.58 per share as a result of our stock option exchange program effective October 1, 2010.

The intrinsic value of option exercises during fiscal 2011 and 2010 was $0.2 million and $0.5 million, respectively. Cash received from stock option exercises in fiscal 2011 and 2010 was $0.9 million and $0.7 million respectively. We did not realize any gross tax benefits in connection with these exercises.

Restricted Stock Units

Restricted stock units are converted into shares of our common stock upon vesting on a one-for-one basis. The vesting of restricted stock units is subject to the employee's continuing service to us. Restricted stock unit activity under our equity plans is set forth below:



	Number of Shares		Weighted Average Grant Date Fair Value
Restricted stock units at December 26, 2009	1,491,678		$	18.51
Granted	776,318		14.57
Vested	(464,050	)	18.95
Canceled	(431,034	)	17.99
Restricted stock units at December 25, 2010	1,372,912		16.29
Granted	687,645		9.94
Vested	(510,330	)	16.70
Canceled	(242,924	)	15.82
Restricted stock units at December 31, 2011	1,307,303		12.88
Granted	1,630,210		5.50
Vested	(484,540	)	13.99
Canceled	(224,027	)	8.78
Restricted stock units at December 29, 2012	2,228,946		$	7.66

On May 4, 2012, we granted 405,000 restricted stock units to certain of our senior executives that will vest upon achievement of specified performance criteria based on the Company's 2013 operating cash flow levels. The restricted stock units will be earned only if performance targets established by the Compensation Committee are met. Compensation cost associated with these awards are recognized on an accelerated attribution model and ultimately based on whether or not satisfaction of the performance criteria is probable.

On November 6, 2012, we granted 120,000 restricted stock units to certain of our senior executives of MicroProbe that will vest upon achievement of specified performance criteria based on the Company's 2013 and 2014 revenue and gross profits levels. The restricted stock units will be earned only if the performance targets established by the Compensation Committee are met. Compensation cost associated with these awards are recognized on an accelerated attribution model and ultimately based on whether or not satisfaction of the performance criteria is probable.

During fiscal 2012, we recorded $0.4 million, of stock-based compensation expense related to these awards based on the assessed probability of attainment of the performance criteria.

The total fair value of restricted stock units vested during fiscal 2012, 2011 and 2010 was $2.9 million, $4.6 million and $6.0 million, respectively.

Employee Stock Purchase Plan

At our 2012 Annual Meeting, our stockholders also approved an amended and restated Employee Stock Purchase Plan (the "2012 ESPP"). The 2012 ESPP does not significantly change the provisions of the 2002 Employee Stock Purchase Plan (the "2002 ESPP"), however, it does remove the annual increase to shares available for issuance and fixes the number of shares reserved for issuance under the 2012 ESPP at 4.0 million shares. The offering periods under the 2012 ESPP are a 12 month fixed offering period commencing on February 1 of each calendar year and ending on January 31 of the subsequent calendar year, and a six month fixed offering period commencing on August 1 of each calendar year and ending on January 31 of the subsequent calendar year.

The price of the common stock purchased is 85% of the lesser of the fair market value of the common stock on the first day of the applicable offering period or the last day of each purchase period.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

Stock-Based Compensation

We account for all stock-based compensation to employees and directors, including grants of stock options, as stock-based compensation costs in the Consolidated Financial Statements based on the fair value measured as of the date of grant. These costs are recognized as an expense in the Consolidated Statements of Operations over the requisite service period and increase additional paid-in capital.

The table below shows the stock-based compensation expense included in the Consolidated Statement of Operations (in thousands):



	Fiscal Years Ended
	December 29, 2012		December 31, 2011		December 25, 2010
Stock-based compensation expense included in:
Cost of revenues(1)	$	2,588	$	3,473	$	3,733
Research and development	4,262		4,293		5,610
Selling, general and administrative(2)	6,199		6,083		8,270
Restructuring charges, net	—		—		190
Total stock-based compensation	13,049		13,849		17,803
Tax effect on stock-based compensation	—		—		—
Total stock-based compensation, net of tax	$	13,049	$	13,849	$	17,803


(1)	Fiscal 2011 includes $0.3 million of net stock-based compensation expense resulting from the modification and acceleration of certain stock options and restricted stock units to a former executive in conjunction with a separation agreement and mutual release.

(2)

Fiscal 2010 includes $0.5 million of stock-based compensation expense and an offsetting benefit of $0.7 million related to the reversal of previously recognized expense for unvested stock options resulting from the modification and acceleration of the vesting of certain stock options and restricted stock units awarded to our former executive members in conjunction with their departure from the Company (See Note 16—Departure of Executive Officers ). Additionally, fiscal 2010 includes $0.1 million of net stock-based compensation expense resulting from the modification and acceleration of the vesting of certain stock options and restricted stock units awarded to former members of the Board of Directors in conjunction with their departure from the Company.

Stock Options

The exercise price of each stock option equals the market price of our stock on the date of grant. Most options are scheduled to vest over three to four years and expire five to ten years from the grant date. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. In addition, we estimate forfeitures when recognizing compensation expense, and adjust our estimates of forfeitures over the requisite service period based on the extent to which actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures are recognized as a change in estimate in the period of change and will also impact the amount of compensation expense to be recognized in future periods.

The following weighted-average assumptions were used in the estimated grant-date fair value calculations for stock options granted in fiscal 2012, 2011 and 2010. The re-granted options from our stock exchange program are excluded from this table.



	Fiscal Years Ended
	December 29, 2012		December 31, 2011		December 25, 2010
Stock Options:
Dividend yield	—	%	—	%	—	%
Expected volatility	48.44	%	50.30	%	50.89	%
Risk-free interest rate	0.67	%	1.67	%	1.23	%
Expected life (in years)	4.75		4.26		4.42

Our computation of expected volatility was based on a combination of historical and market-based implied volatility from traded options on our common stock. We believe that including market-based implied volatility in the calculation of expected volatility results in a more accurate measure of the volatility expected in future periods. Risk-free interest rates are yields for zero-coupon U.S. Treasury notes maturing approximately at the end of the expected option life. We determine the expected term by considering several factors, including historical option exercise behavior, post vesting turnover rates, contractual terms and vesting periods of the options granted. In fiscal 2010, we granted 2.0 million stock options to employees with vesting periods that range from two to three years and contractual terms that range from five to seven years. Because we did not have sufficient historical data for stock options with similar vesting or contractual terms, the simplified method was applied for deriving the expected term for these stock options. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting. The mid-point between the vesting date and the expiration date is used for the expected term under this method.

During fiscal 2012, we granted 70,000 stock options under our approved plans with a weighted average grant-date fair value of $2.17 per share. During fiscal 2011, we granted 459,750 stock options under our approved plans with a weighted average grant-date fair value of $4.06 per share. Excluding the 679,864 stock options that were re-granted on October 1, 2010, we granted 2,745,445 stock options in fiscal 2010 with the weighted average grant-date fair value of $4.46 per share.

As of December 29, 2012, the unamortized stock-based compensation balance related to stock options was $3.8 million after estimated forfeitures, which will be recognized over an estimated period of 1.3 years based on the weighted average days to vest.

Stock Option Exchange

On October 1, 2010, we completed an offer to exchange certain outstanding employee stock options to purchase shares of the Company's common stock. Eligible for the exchange were outstanding options, vested or unvested, held by current employees (excluding directors and executive officers) with an exercise price greater than or equal to $13.63 per share. Subject to the terms and conditions of the exchange offer, we accepted for exchange and cancelled options to purchase an aggregate of 2,779,782 shares with a weighted average exercise price of $29.58 per share, and issued new options to purchase an aggregate of 679,864 shares with an exercise price of $8.61 per share, the closing stock price of our common stock on October 1, 2010. The new options were granted under our 2002 Plan and vest 33% on the first anniversary of the vesting commencement date and on a monthly basis thereafter for a period of an additional two years. The assumptions that were used in estimating grant-date fair value for these re-granted stock options were 0% dividend yield, 52.61% of expected volatility, 3.35 years of expected life and 0.74% of risk-free interest rate. The grant-date fair value of the re-granted stock options was $3.25 per share. The incremental compensation expense resulting from the completion of the exchange offer did not have a material impact on our consolidated financial position, results of operations and cash flows.

Employee Stock Purchase Plan

During the fiscal 2012, we issued 533,077 shares under our approved employee stock purchase plans. As of December 29, 2012, we had $0.1 million of total unrecognized stock-based compensation expense, which will be recognized over the weighted average period of approximately one month. Compensation expense is calculated using the fair value of the employees' purchase rights under the Black-Scholes model. The following assumptions were used in estimating the fair value of employees' purchase rights under the approved employee stock purchase plans:



	Fiscal Years Ended
	December 29, 2012		December 31, 2011		December 25, 2010
Employee Stock Purchase Plan:
Dividend yield	—	%	—	%	—	%
Expected volatility	46.44	%	53.47	%	41.25	%
Risk-free interest rate	0.11	%	0.23	%	0.24	%
Expected life (in years)	0.8		0.8		0.7

Restricted Stock Units

The fair value of restricted stock units is determined using the market closing price of our common stock on the grant date, and compensation cost is recognized over the vesting period on a straight line basis. The restricted stock units generally vest over four years.

During fiscal 2012, 2011 and 2010, we granted 1,630,210 shares, 687,645 shares and 776,318 shares of restricted stock units under our 2002 and 2012 Plans with the weighted average grant-date fair values of $5.50, $9.94 and $14.57 per share, respectively. As of December 29, 2012, the unamortized stock-based compensation balance related to restricted stock units was $7.8 million after estimated forfeitures, which will be recognized over an estimated period of 1.7 years based on the weighted average days to vest.

Deferred tax assets and liabilities are recognized for the future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the differences are expected to be reversed. Significant deferred tax assets and liabilities consist of the following (in thousands):

Unrealized investment gains	(42		)	(102		)
Total deferred tax liabilities	(27,921		)	(102		)
Net deferred tax assets	$	4,348		$	7,069

We are required to evaluate the realizability of our deferred tax assets in both our U.S. and non-U.S. jurisdictions on an ongoing basis in accordance with GAAP to determine whether there is a need for a valuation allowance with respect to such deferred tax assets. During fiscal 2012 and 2011, we maintained a valuation allowance against our U.S. deferred tax assets. We intend to maintain a valuation allowance until sufficient positive evidence exists to support the realization of such deferred tax assets.

Included in the $26.4 million income tax benefit for the year ended December 29, 2012 is a $25.5 million tax benefit from the release of valuation allowance of our deferred tax assets ("DTAs"). In connection with our acquisition of MicroProbe during the year ended December 29, 2012, deferred tax liabilities ("DTLs") were established on the acquired identifiable intangible assets. These DTLs exceeded the acquired DTAs by $25.5 million. These DTLs exceeded the acquired DTAs by $25.5 million and created additional sources of income to realize a tax benefit for our DTAs. As such, authoritative guidance requires the impact on the acquiring company's deferred tax assets and liabilities caused by an acquisition be recorded in the acquiring company's financial statements outside of acquisition accounting. Accordingly, the valuation allowance on a portion of our DTAs was released and resulted in an income tax benefit of $25.5 million.

During fiscal 2011, we determined that it is more likely than not that the deferred tax assets of a non-U.S. jurisdiction will be realized after considering all positive and negative evidence. Positive evidence included finalization of our current restructuring activity for the related foreign jurisdiction. It also included conclusion that such location would continue to be in operation for the foreseeable future and future taxable income sufficient to realize such deferred tax assets prior to the expiration of existing net operating loss carryforwards due to a change in the entity's structure to a cost-plus arrangement. Our conclusion that it is more likely than not that such deferred tax assets will be realized is strongly influenced by the expectation that such location will continue to be in operation for the foreseeable future. We believe such conclusion is reasonable in light of our current operational structure and forecasted operations, both for the foreign jurisdiction and our consolidated operations; however, such conclusion is inherently uncertain. Therefore, if we have material unforeseen losses or are required to restructure our non-U.S. operations to further align our operating expense structure with our expected revenues, then its ability to generate sufficient income necessary to realize a portion of the deferred tax assets may be reduced and an additional charge to increase the valuation allowance may be recorded.

The valuation allowance against deferred tax assets consisted of the following activity for the fiscal years 2012, 2011 and 2010 (in thousands):



Description	Balance at Beginning of Year		Additions		Reduction			Balance at End of Year
Allowance against deferred tax assets
Year ended December 25, 2010	$	59,097	$	68,634	$	—		$	127,731

At December 29, 2012, we had Federal research and development tax credit, net operating loss, and foreign tax credit carryforwards of $18.5 million, $284.2 million and $1.6 million, which will expire at various dates from 2016 through 2032. We had alternative minimum tax credits of $2.2 million which do not expire. We had California research credit and net operating loss carryforwards of $22.7 million and $266.7 million, respectively. The California research credit can be carried forward indefinitely while California net operating loss carryforwards will expire at various dates from 2030 through 2032. We had Singapore net operating loss carryforwards of $12.2 million which can be carried forward indefinitely.

U.S. income taxes and foreign withholding taxes associated with the repatriation of earnings of foreign subsidiaries were not provided for $6.5 million of undistributed earnings of its foreign subsidiaries. We intend to reinvest these earnings indefinitely in our foreign subsidiaries. If these earnings were distributed to the U.S. in the form of dividends or otherwise, or if the shares of the relevant foreign subsidiaries were sold or otherwise transferred, we would be subject to additional U.S. income taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes, of approximately $42,000. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable.

During fiscal 2012, 2011 and 2010, there were no tax benefits associated with the exercise of employee stock options and other employee stock programs.

The following table reflects changes in the unrecognized tax benefits (in thousands):



	Fiscal Years Ended

Settlements	—			(81		)	(2,000		)
Unrecognized tax benefit ending balance	$	17,181		$	17,752		$	17,500

At December 29, 2012, we had gross tax-effected unrecognized tax benefits of $17.2 million of which $2.7 million if recognized, would impact the effective tax rate.

We recognize interest charges and penalties related to uncertain tax positions as part of the income tax provision. We recognized interest charges and penalties of $0.3 million and $12,000 in fiscal 2012 and fiscal 2011, respectively, and an interest benefit of $0.3 million for fiscal 2010. As of December 29, 2012 and December 31, 2011, we have accrued total interest charges and penalties of $0.4 million and $0.7 million, respectively, related to uncertain tax positions.

The amount of income taxes we pay is subject to ongoing audits by Federal, state and foreign tax authorities which might result in proposed assessments. Our estimate for the potential outcome for any uncertain tax issue is judgmental in nature. However, we believe we have adequately provided for any reasonably foreseeable outcome related to those matters. Our future results may include favorable or unfavorable adjustments to our estimated tax liabilities in the period the assessments are made or resolved or when statutes of limitation on potential assessments expire. As of December 29, 2012 changes to our uncertain tax positions in the next 12 months that are reasonably possible are not expected to have a significant impact on our financial position or results of operations.

We and our subsidiaries file income tax returns in the U.S. Federal jurisdiction, various states and non U.S jurisdictions. The material jurisdictions in which we are subject to potential examination by tax authorities for the tax years after 2003 include, among others, the U.S. (Federal and California), Singapore, and Japan.

On January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which includes retroactive extension of the research credit from January 1, 2012 through December 31, 2013. This enacted tax law will result in an increase in the Company’s gross deferred tax asset by approximately $0.4 million, offset by a valuation allowance, during the first quarter of 2013.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Employee Benefit Plans	12 Months Ended
Employee Benefit Plans	Dec. 29, 2012
Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	Employee Benefit Plans We have an employee savings plan that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. We match up to 50% of an eligible employee's contributions to a maximum of the first 3% of the eligible employee's contributions through a fiscal year. As part of the acquisition, MicroProbe matches up to 25% of an eligible employee's contributions to a maximum of the first 6% of the eligible employee's contributions through a fiscal year. We also provide a tax-qualified profit sharing retirement plan for the benefit of eligible employees in the U.S. The plan is designed to provide employees with an accumulation of funds for retirement on a tax-deferred basis and provide for annual discretionary employer contributions. We suspended our match under the 401(k) plan in the second quarter of fiscal 2009 as part of our cost reduction efforts. During the third quarter of fiscal 2010, we reinstated the employer match feature due to the progress that we had made in streamlining and simplifying our operations and reducing operating costs as we continue to focus on returning the Company to profitability. The total charge to operations under the 401(k) and the profit sharing retirement plans for fiscal 2012, 2011 and 2010 aggregated $0.8 million, $0.6 million and $0.2 million, respectively.

(1)	In the second quarter of fiscal 2011, we recorded a tax benefit in the amount of $2.5 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2011.


(2)	In the second quarter of fiscal 2012, we recorded a tax benefit in the amount of $1.6 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2012.

In the fourth quarter of fiscal 2012, we recorded an income tax benefit in the amount of $25.5 million from the release of deferred tax asset valuation allowances due to deferred tax liabilities established on the acquired identifiable intangible assets from our acquisition of MicroProbe and $3.3 million benefit from the settlement of patent litigation in conjunction with the acquisition of MicroProbe. The fourth quarter of fiscal 2012 includes the following Microprobe operating activity: $19.8 million in revenue, $5.4 million amortization of intangibles, $2.6 million release of pre-existing backlog, $3.5 million release of inventory fair value step-up and $0.2 million charge for step-up depreciation on fixed assets resulting in a net loss of $6.4 million.

The entire disclosure for the quarterly financial data in the annual financial statements. The disclosure may include a tabular presentation of financial information for each fiscal quarter for the current and previous year, including revenues, gross profit, income or loss before extraordinary items and earnings per share data. It also includes an indication if the information in the note is unaudited, comments on the aggregate effect of year-end adjustments, and an explanation of matters or transactions that affect comparability or are pertinent to an understanding of the information furnished.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In the first fiscal quarter of 2013, we implemented a restructuring plan (the "Q1 2013 Restructuring Plan") which resulted in the reduction of our global workforce by32 employees across the organization. Total restructuring charges for the quarter will be in the range of $2.6 million to $3.2 million for severance and related benefits and impairment charges for certain equipment. The activities comprising this reduction in workforce will be completed by the end of second quarter fiscal 2013.

Cash and Cash Equivalents

Basis of Consolidation

The consolidated financial statements include our accounts and those of our wholly owned subsidiaries. All material intercompany balances and transactions have been eliminated.

Foreign Currency

Use of Estimates

Business Aquisitions

Cash and cash equivalents consist of deposits and financial instruments which are readily convertible into cash and have original maturities of 90 days or less at the time of acquisition

Marketable Securities

Marketable securities consist primarily of highly liquid investments with maturities of greater than 90 days when purchased. We generally classify our marketable securities at the date of acquisition as available-for-sale. These securities are reported at fair value with the related unrealized gains and losses included in "Accumulated other comprehensive income", a component of stockholder's equity, net of tax. Any unrealized losses which are considered to be other-than-temporary impairments are recorded in "Other income, net" in the Consolidated Statements of Operations. Realized gains (losses) on the sale of marketable securities are determined using the specific-identification method and recorded in "Other income, net" in the Consolidated Statements of Operations. We measure our cash equivalents and marketable securities at fair value.

Fair Value of Financial Instruments


•	Level 1 valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.


•	Level 2 inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices near the reporting date in markets that are less active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.


•	Level 3 valuations are based on unobservable inputs to the valuation methodology and include our own data about assumptions market participants would use in pricing the asset or liability based on the best information available under the circumstances.

Each level of input has different levels of subjectivity and difficulty involved in determining fair value.

Foreign Exchange Management

Restricted Cash

Under the terms of one of our facility leases, we provide security to the landlord in the form of letters of credit.

Derivatives, Methods of Accounting, Derivatives Not Designated or Qualifying as Hedges [Policy Text Block]

We do not use derivative financial instruments for speculative or trading purposes. Our derivative instruments, which are generally settled in the same quarter, are not designated as hedging instruments. We record the fair value of these contracts as of the end of our reporting period to our Consolidated Balance Sheet with changes in fair value recorded within "Other income, net" in our Consolidated Statement of Operations for both realized and unrealized gains and losses.

Fair Value


•	Level 1—Quoted prices in active markets for identical assets or liabilities.


•	Level 2—Inputs, other than the quoted prices in active markets, such as quoted prices for similar assets or liabilities, quoted prices near the reporting date in markets that are less active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.


•	Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Fiscal Period, Policy

Fiscal Year

Our fiscal year ends on the last Saturday in December. The fiscal years ended on December 29, 2012 and December 25, 2010, respectively, consisted of 52 weeks and the fiscal year ended on December 31, 2011 consisted of 53 weeks.

[1]	In the fourth quarter of fiscal 2012, we recorded an income tax benefit in the amount of $25.5 million from the release of deferred tax asset valuation allowances due to deferred tax liabilities established on the acquired identifiable intangible assets from our acquisition of MicroProbe and $3.3 million benefit from the settlement of patent litigation in conjunction with the acquisition of MicroProbe. The fourth quarter of fiscal 2012 includes the following Microprobe operating activity: $19.8 million in revenue, $5.4 million amortization of intangibles, $2.6 million release of pre-existing backlog, $3.5 million release of inventory fair value step-up and $0.2 million charge for step-up depreciation on fixed assets resulting in a net loss of $6.4 million.
[2]	In the second quarter of fiscal 2012, we recorded a tax benefit in the amount of $1.6 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2012.
[3]	In the second quarter of fiscal 2011, we recorded a tax benefit in the amount of $2.5 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2011.

The portion of profit or loss for the period, net of income taxes, which is attributable to the parent.

Number of [basic] shares or units, after adjustment for contingently issuable shares or units and other shares or units not deemed outstanding, determined by relating the portion of time within a reporting period that common shares or units have been outstanding to the total time in that period.

[1]	In the fourth quarter of fiscal 2012, we recorded an income tax benefit in the amount of $25.5 million from the release of deferred tax asset valuation allowances due to deferred tax liabilities established on the acquired identifiable intangible assets from our acquisition of MicroProbe and $3.3 million benefit from the settlement of patent litigation in conjunction with the acquisition of MicroProbe. The fourth quarter of fiscal 2012 includes the following Microprobe operating activity: $19.8 million in revenue, $5.4 million amortization of intangibles, $2.6 million release of pre-existing backlog, $3.5 million release of inventory fair value step-up and $0.2 million charge for step-up depreciation on fixed assets resulting in a net loss of $6.4 million.
[2]	In the second quarter of fiscal 2012, we recorded a tax benefit in the amount of $1.6 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2012.
[3]	In the second quarter of fiscal 2011, we recorded a tax benefit in the amount of $2.5 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2011.

[1]	In the fourth quarter of fiscal 2012, we recorded an income tax benefit in the amount of $25.5 million from the release of deferred tax asset valuation allowances due to deferred tax liabilities established on the acquired identifiable intangible assets from our acquisition of MicroProbe and $3.3 million benefit from the settlement of patent litigation in conjunction with the acquisition of MicroProbe. The fourth quarter of fiscal 2012 includes the following Microprobe operating activity: $19.8 million in revenue, $5.4 million amortization of intangibles, $2.6 million release of pre-existing backlog, $3.5 million release of inventory fair value step-up and $0.2 million charge for step-up depreciation on fixed assets resulting in a net loss of $6.4 million.
[2]	In the second quarter of fiscal 2012, we recorded a tax benefit in the amount of $1.6 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2012.
[3]	In the second quarter of fiscal 2011, we recorded a tax benefit in the amount of $2.5 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2011.

The aggregate amount of write-downs for impairments recognized during the period for long lived assets held for use (including those held for disposal by means other than sale).

[1]	In the fourth quarter of fiscal 2012, we recorded an income tax benefit in the amount of $25.5 million from the release of deferred tax asset valuation allowances due to deferred tax liabilities established on the acquired identifiable intangible assets from our acquisition of MicroProbe and $3.3 million benefit from the settlement of patent litigation in conjunction with the acquisition of MicroProbe. The fourth quarter of fiscal 2012 includes the following Microprobe operating activity: $19.8 million in revenue, $5.4 million amortization of intangibles, $2.6 million release of pre-existing backlog, $3.5 million release of inventory fair value step-up and $0.2 million charge for step-up depreciation on fixed assets resulting in a net loss of $6.4 million.
[2]	In the second quarter of fiscal 2012, we recorded a tax benefit in the amount of $1.6 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2012.
[3]	In the second quarter of fiscal 2011, we recorded a tax benefit in the amount of $2.5 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2011.

[1]	In the fourth quarter of fiscal 2012, we recorded an income tax benefit in the amount of $25.5 million from the release of deferred tax asset valuation allowances due to deferred tax liabilities established on the acquired identifiable intangible assets from our acquisition of MicroProbe and $3.3 million benefit from the settlement of patent litigation in conjunction with the acquisition of MicroProbe. The fourth quarter of fiscal 2012 includes the following Microprobe operating activity: $19.8 million in revenue, $5.4 million amortization of intangibles, $2.6 million release of pre-existing backlog, $3.5 million release of inventory fair value step-up and $0.2 million charge for step-up depreciation on fixed assets resulting in a net loss of $6.4 million.
[2]	In the second quarter of fiscal 2012, we recorded a tax benefit in the amount of $1.6 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2012.
[3]	In the second quarter of fiscal 2011, we recorded a tax benefit in the amount of $2.5 million from the release of a deferred tax valuation allowance recorded in a non-U.S. jurisdiction. This benefit resulted in an overall income tax benefit, rather than an income tax provision in the second quarter of fiscal 2011.
